This includes the following trees: 25, 26, 27, 28, 106, 107, 116, 115, 114, 113. On the southern property line adjacent to the existing residential near Charter Oaks Drive we will setback parking 15’ from the property line. This will allow for the preservation of the majority of the trees along this edge of the project. This applies to the following trees: 124 – 132, 134 – 141. Along the railroad right of way the majority of our improvements will be in areas of the site that are already developed with parking and other improvements. This should allow for the preservation of many trees in this area including: 324, 326-346. Of course, if any of these trees must be removed, we will follow the tree mitigation requirements.

Air Quality & Greenhouse Gas Assessment 1 March 2011  EXECUTIVE SUMMARY    The purpose of this Air Quality and Greenhouse Gas Assessment is to evaluate potential short‐  and long‐term air quality and greenhouse gas impacts resulting from implementation of the  proposed Albright Way Development project (project).  The project is located in the Town of  Los Gatos (Town), along Albright Way, southeast of the State Route 85 (SR‐85) and Winchester  Boulevard interchange.       The project proposes a Planned Development zoning that will allow for flexibility in the  ultimate mix of land uses on the project site.  The project may consist of office alone or a mix of  office and high‐density /senior residential units.  As currently proposed, the project could  include up to a maximum of 550,000 square feet of office space, or a combination of less office  space with residential uses.  Residential uses could include up to a maximum of 516 high‐ density dwelling units or 600 senior residential uses.  This Air Quality and Greenhouse Gas  Assessment evaluates Scenario 1 as identified in the Albright Way Development Traffic Impact  Analysis (Traffic Impact Analysis), prepared by Hexagon Transportation Consultants, Inc. on  March 17, 2011.  Scenario 1 consists of the replacement of 250,000 square feet of existing office  park buildings with new office buildings totaling 550,000 square feet.  Under Scenario 1, the  new office buildings would provide an additional 300,000 square feet of office space and result  in additional 3,126 daily vehicle trips.  Three parking structures are also proposed under this  Scenario.  As noted, the Planned Development zoning will provide flexibility for mixed use  scenarios, provided that the air quality and GHG impacts of those scenarios are not  substantially more severe than the air quality and GHG impacts of Scenario 1.    Construction activities would consist of demolition of existing buildings, site grading,  trenching, paving, building construction, and architectural coating.  Staging for construction  equipment would occur within the boundaries of the project site.     Temporary Impacts.  Based upon the results of the analysis, construction emissions would not  exceed the Bay Area Air Quality Management District thresholds with implementation of  recommended mitigation measures.  Short‐term construction impacts would be considered less  than significant.     Long‐Term Impacts.  The analysis has demonstrated that project implementation would result  in less than significant long‐term impacts.  Carbon monoxide hot‐spots impacts would also be  less than significant with implementation of recommended mitigation within the project’s  Traffic Impact Analysis.  The proposed project would result in less than significant impacts for all  long‐term operational emissions.    Greenhouse Gas Emissions Impacts.  The proposed project would generate minimal amounts of  GHG emissions as a result of construction activities, and would result in a less than significant  impact.  Long‐term operational greenhouse gas emissions would be less than significant with  implementation of the recommended mitigation measure.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 2 March 2011  Cumulative Impacts.  The proposed project would be consistent with the Bay Area Air Quality  Management District’s 2010 Clean Air Plan, as the proposed project complies with the goals and  policies of the General Plan and does not exceed the Bay Area Air Quality Management District’s  short‐ and long‐term significance criteria.  The proposed project would result in a less than  significant impact for cumulative long‐ and short‐term operational emissions.                     Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 3 March 2011  1.0 INTRODUCTION    The purpose of this Air Quality and Greenhouse Gas Assessment is to evaluate potential short‐  and long‐term air quality and greenhouse gas (GHG) impacts resulting from implementation of  the proposed Albright Way Development project (project) in the Town of Los Gatos (Town).     1.1 PROJECT LOCATION    The project is located in the Town of Los Gatos, California; refer to Exhibit 1, Regional Vicinity.   Specifically, the project site is located along Albright Way, southeast of the State Route 85 (SR‐ 85) and Winchester Boulevard interchange; refer to Exhibit 2, Local Vicinity Map.      1.2 PROJECT CHARACTERISTICS    The project proposes a Planned Development zoning that will all for flexibility in the ultimate  mix of land uses on the site.  The project may consist of office alone or a mix of office and high‐ density /senior residential units.  As currently proposed, the project could include up to a  maximum of 550,000 square feet of office space, or a combination of less office space with  residential uses.  Residential uses could include up to a maximum of 516 high‐density dwelling  units or 600 senior residential uses.  This Air Quality and Greenhouse Gas Assessment  evaluates Scenario 1 as identified in the Albright Way Development Traffic Impact Analysis (Traffic  Impact Analysis), prepared by Hexagon Transportation Consultants, Inc. on March 17, 2011.  An  evaluation of each of the potential land use scenarios indicates that the development of the  project site as all office uses would result in the greatest amount of traffic being added to the  roadway system.1   Therefore, as vehicle trips are typically largest source of air quality and  greenhouse gas (GHG) emissions for development projects, this analysis evaluates the “worst‐ case” project scenario consisting of the replacement of 250,000 square feet (s.f.) of existing office  park buildings with new buildings totaling 550,000 s.f.; refer to Exhibit 3, Site Plan.      As noted, the Planned Development zoning will provide flexibility for mixed use scenarios,  provided that the air quality and GHG impacts of those scenarios are not substantially more  severe than the air quality and GHG impacts of Scenario 1. The Town has developed the  following additional illustrative land uses scenarios:    • Scenario 1: Replacement of the 250,000 s.f. of existing office park buildings on the site with  new office buildings totaling 550,000 s.f.  • Scenario 2: Minimum of 200,000 s.f. new office plus 141,000 s.f. (remaining) office  • Scenario 3: 200,000 s.f. new office plus up to 516 high‐density units   • Scenario 4: 200,000 s.f. new office plus up to 600 senior units     1   Hexagon Transportation Consultants, Inc., Albright Way Development Traffic Impact Analysis, March 17,  2011.  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 4 March 2011  Because the office use would generate more daily and peak hour trips than would residential,  this study first presents the analysis of a proposed project scenario consisting of the replacement  of the 250,000 s.f. of existing office park buildings on the site with new office buildings totaling  550,000 s.f.  Then, in order to determine whether the addition of residential uses would generate  any greater impacts than the 550,000 s.f. office scenario, supplemental analyses were completed  for the additional scenarios.    The project site is bound by Winchester Boulevard, a rail line and SR‐85 to the north and west, a  residential neighborhood and the Los Gatos Creek Trail to the east, and an office building to the  south.  The design goals for future buildings on the project site are to fit into that transitional  environment and to provide adequate density for a transit oriented development to meet the  Townʹs goals.  In order to work with the project site’s natural grades, the site design would  utilize walls, terraces, and landscaped steps in natural materials that would become an  extension of the building architecture, and create useful outdoor social gathering spaces.     Construction activities would consist of demolition of existing buildings, site grading,  trenching, paving, building construction, and architectural coating.  Staging for construction  equipment would occur within the boundaries of the project site.          PACIFIC OCEAN STANISLAUS

2.0 EXISTING AIR QUALITY SETTING    2.1  ENVIRONMENTAL SETTING     The California Air Resources Board (CARB) divides the State into 15 air basins that share  similar meteorological and topographical features.  The project site is located within the San  Francisco Bay Area Air Basin (Basin).  This Basin comprises all of Alameda, Contra Costa,  Marin, Napa, San Francisco, San Mateo, and Santa Clara counties, the southern portion of  Sonoma, and the southwestern portion of Solano County.  Air quality in this area is determined  by such natural factors as topography, meteorology, and climate, in addition to the presence of  existing air pollution sources and ambient conditions.  These factors along with applicable  regulations are discussed below.    The Town of Los Gatos is located within the Santa Clara Valley climatological subregion of the  Basin.  The Santa Clara Valley is bounded by the San Francisco Bay to the north and by  mountains to the east, south, and west.      The climate is dominated by the strength and location of a semi‐permanent, subtropical high‐ pressure cell.  During the summer, the Pacific high pressure cell is centered over the  northeastern Pacific Ocean resulting in stable meteorological conditions and a steady  northwesterly wind flow.  Upwelling of cold ocean water from below to the surface because of  the northwesterly flow produces a band of cold water off the California coast.  The cool and  moisture‐laden air approaching the coast from the Pacific Ocean is further cooled by the  presence of the cold water band resulting in condensation and the presence of fog and stratus  clouds along the Northern California coast.  In the winter, the Pacific high‐pressure cell  weakens and shifts southward resulting in wind flow offshore, the absence of upwelling, and  the occurrence of storms.  Weak inversions coupled with moderate winds result in a low air  pollution potential.    Wind Patterns    During the summer, winds flowing from the northwest are drawn inland through the Golden  Gate and over the lower portions of the San Francisco Peninsula.  Immediately south of Mount  Tamalpais, the northwesterly winds accelerate considerably and come more directly from the  west as they stream through the Golden Gate.  This channeling of wind through the Golden  Gate produces a jet that sweeps eastward and splits off to the northwest toward Richmond and  to the southwest toward San Jose when it meets the East Bay hills.    Wind speeds may be strong locally in areas where air is channeled through a narrow opening,  such as the Carquinez Strait, the Golden Gate or the San Bruno gap.  For example, the average  wind speed at San Francisco International Airport in July is about 17 knots (from 3:00 p.m. to  4:00 p.m.), compared with only seven knots at San Jose and less than six knots at the Farallon  Islands.  The air flowing in from the coast to the Central Valley, called the sea breeze, begins  developing at or near ground level along the coast in late morning or early afternoon.  As the  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 9 March 2011  day progresses, the sea breeze layer deepens and increases in velocity while spreading inland.   The depth of the sea breeze depends in large part upon the height and strength of the inversion.   If the inversion is low and strong, and hence stable, the flow of the sea breeze will be inhibited  and stagnant conditions are likely to result.    In the winter, the Basin frequently experiences stormy conditions with moderate to strong  winds, as well as periods of stagnation with very light winds.  Winter stagnation episodes are  characterized by nighttime drainage flows in coastal valleys.  Drainage is a reversal of the usual  daytime air‐flow patterns; air moves from the Central Valley toward the coast and back down  toward the Bay from the smaller valleys within the Basin.    Temperature    Summertime temperatures in the Basin are determined in large part by the effect of differential  heating between land and water surfaces. Because land tends to heat up and cool off more  quickly than water, a large‐scale gradient (differential) in temperature is often created between  the coast and the Central Valley, and small‐scale local gradients are often produced along the  shorelines of the ocean and bays.  The temperature gradient near the ocean is also exaggerated,  especially in summer, because of the upwelling of cold ocean bottom water along the coast.  On  summer afternoons the temperatures at the coast can be 35 degrees Fahrenheit (ºF) cooler than  temperatures 15 to 20 miles inland.  At night this contrast usually decreases to less than 10ºF.  In  the winter, the relationship of minimum and maximum temperatures is reversed.  During the  daytime the temperature contrast between the coast and inland areas is small, whereas at night  the variation in temperature is large.    Precipitation    The Basin is characterized by moderately wet winters and dry summers.  Winter rains account  for about 75 percent of the average annual rainfall.  The amount of annual precipitation can  vary greatly from one part of the Basin to another even within short distances.  In general, total  annual rainfall can reach 40 inches in the mountains, but it is often less than 16 inches in  sheltered valleys.  During rainy periods, ventilation (rapid horizontal movement of air and  injection of cleaner air) and vertical mixing are usually high, and thus pollution levels tend to be  low. However, frequent dry periods do occur during the winter where mixing and ventilation  are low and pollutant levels build up.    Air Pollution Potential    The potential for high pollutant concentrations developing at a given location depends upon the  quantity of pollutants emitted into the atmosphere in the surrounding area or upwind, and the  ability of the atmosphere to disperse the contaminated air.  The topographic and climatological  factors discussed above influence the atmospheric pollution potential of an area.  Atmospheric  pollution potential, as the term is used here, is independent of the location of emission sources  and is instead a function of factors described below.  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 10 March 2011  Wind Circulation    Low wind speed contributes to the buildup of air pollution because it allows more pollutants to  be emitted into the air mass per unit of time.  Light winds occur most frequently during periods  of low sun (fall and winter, and early morning) and at night.  These are also periods when air  pollutant emissions from some sources are at their peak, namely, commute traffic (early  morning) and wood burning appliances (nighttime). The problem can be compounded in  valleys, when weak flows carry the pollutants upvalley during the day, and cold air drainage  flows move the air mass downvalley at night.  Such restricted movement of trapped air  provides little opportunity for ventilation and leads to buildup of pollutants to potentially  unhealthful levels.    Inversions    An inversion is a layer of warmer air over a layer of cooler air. Inversions affect air quality  conditions significantly because they influence the mixing depth, which is the vertical depth in  the atmosphere available for diluting air contaminants near the ground.  The highest air  pollutant concentrations in the Basin generally occur during inversions.      There are two types of inversions that occur regularly in the Basin.  One is more common in the  summer and fall, while the other is most common during the winter.  The frequent occurrence  of elevated temperature inversions in summer and fall months acts to cap the mixing depth,  limiting the depth of air available for dilution.  Elevated inversions are caused by subsiding air  from the subtropical high pressure zone, and from the cool marine air layer that is drawn into  the Basin by the heated low pressure region in the Central Valley.    The inversions typical of winter, called radiation inversions, are formed as heat quickly radiates  from the earthʹs surface after sunset, causing the air in contact with it to rapidly cool.  Radiation  inversions are strongest on clear, low‐wind, cold winter nights, allowing the build‐up of such  pollutants as carbon monoxide and particulate matter.  When wind speeds are low, there is little  mechanical turbulence to mix the air, resulting in a layer of warm air over a layer of cooler air  next to the ground.  Mixing depths under these conditions can be as shallow as 50 to 100 meters,  particularly in rural areas. Urban areas usually have deeper minimum mixing layers because of  heat island effects and increased surface roughness. During radiation inversions downwind  transport is slow, the mixing depths are shallow, and turbulence is minimal, all factors which  contribute to ozone formation.    Although each type of inversion is most common during a specific season, either inversion  mechanism can occur at any time of the year.  Sometimes both occur simultaneously.   Moreover, the characteristics of an inversion often change throughout the course of a day.  The  terrain of the Basin also induces significant variations among subregions.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 11 March 2011  Solar Radiation    The frequency of hot, sunny days during the summer months in the Basin is another important  factor that affects air pollution potential.  It is at the higher temperatures that ozone is formed.   In the presence of ultraviolet sunlight and warm temperatures, reactive organic gases and  oxides of nitrogen react to form secondary photochemical pollutants, including ozone.  Because  temperatures in many of the inland valleys are so much higher than near the coast, the inland  areas are especially prone to photochemical air pollution.  In late fall and winter, solar angles  are low, resulting in insufficient ultraviolet light and warming of the atmosphere to drive the  photochemical reactions.  Ozone concentrations do not reach significant levels in the Basin  during these seasons.    Sheltered Terrain    The hills and mountains in the Basin contribute to the high pollution potential of some areas.   During the day, or at night during windy conditions, areas in the lee sides of mountains are  sheltered from the prevailing winds, thereby reducing turbulence and downwind transport.  At  night, when wind speeds are low, the upper atmospheric layers are often decoupled from the  surface layers during radiation conditions.  If elevated terrain is present, it will tend to block  pollutant transport in that direction.  Elevated terrain also can create a recirculation pattern by  inducing upvalley air flows during the day and reverse downvalley flows during the night,  allowing little inflow of fresh air.    The areas having the highest air pollution potential tend to be those that experience the highest  temperatures in the summer and the lowest temperatures in the winter.  The coastal areas are  exposed to the prevailing marine air, creating cooler temperatures in the summer, warmer  temperatures in winter, and stratus clouds all year.  The inland valleys are sheltered from the  marine air and experience hotter summers and colder winters.  Thus, the topography of the  inland valleys creates conditions conducive to high air pollution potential.    2.2 REGULATORY FRAMEWORK    U.S. ENVIRONMENTAL PROTECTION AGENCY    The EPA is responsible for implementing the Federal Clean Air Act (FCAA), which was first  enacted in 1955 and amended numerous times after.  The FCAA established Federal air quality  standards known as the National Ambient Air Quality Standards (NAAQS).  These standards  identify levels of air quality for “criteria” pollutants that are considered the maximum levels of  ambient (background) air pollutants considered safe, with an adequate margin of safety, to  protect the public health and welfare.  The criteria pollutants are ozone (O3), carbon monoxide  (CO), nitrogen dioxide (NO2, which is a form of nitrogen oxides [NOx]), sulfur dioxide (SO2,  which is a form of sulfur oxides [SOx]), particulate matter less than 10 and 2.5 microns in  diameter (PM10 and PM2.5, respectively), and lead (Pb); refer to Table 1, National and California  Ambient Air Quality Standards.   Albright Way Development Project

California standards for ozone, carbon monoxide (except Lake Tahoe), sulfur dioxide (1- and 24-hour), nitrogen dioxide, suspended particulate matter-PM10 and visibility-reducing particles are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations. In 1990, the California Air Resources Board (CARB) identified vinyl chloride as a toxic air contaminant, but determined that there was not sufficient available scientific evidence to support the identification of a threshold exposure level. This action allows the implementation of health-protective control measures at levels below the 0.010 parts per million ambient concentration specified in the 1978 standard. 2. National standards (other than ozone, particulate matter and those based on annual averages or annual arithmetic mean) are not to be exceeded more than once a year. EPA also may designate an area as attainment/unclassifiable, if: (1) it has monitored air quality data that show that the area has not violated the ozone standard over a three-year period; or (2) there is not enough information to determine the air quality in the area. For PM10, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 μg/m3 is equal to or less than one. For PM2.5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. 3. Concentration is expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 mm of mercury. Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 mm of mercury (1,013.2 millibar); ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas. 4. National Primary Standards: The levels of air quality necessary, with an adequate margin of safety, to protect the public health. 5. The Federal 1-hour ozone standard was revoked on June 15, 2005 in all areas except the 14 8-hour ozone nonattainment Early Action Compact (EAC) areas. 6. The Environmental Protection Agency revoked the annual PM10 standard in 2006 (effective December 16, 2006). 7. To attain this standard, the 3-year average of the 98th percentile of the daily maximum 1-hour average at each monitor within an area must not exceed 0.100 ppm (effective January 22, 2010). Note that EPA standards are in units of ppb and California standards are in units of ppm. Source: California Air Resources Board and U.S. Environmental Protection Agency, September 8, 2010. Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 13 March 2011  CALIFORNIA AIR RESOURCES BOARD    CARB administers the air quality policy in California.  The California Ambient Air Quality  Standards (CAAQS) were established in 1969 pursuant to the Mulford‐Carrell Act.  These  standards, included with the NAAQS in Table 1, are generally more stringent and apply to  more pollutants than the NAAQS.  In addition to the criteria pollutants, CAAQS have been  established for visibility reducing particulates, hydrogen sulfide, and sulfates.      The California Clean Air Act (CCAA), which was approved in 1988, requires that each local air  district prepare and maintain an Air Quality Management Plan (AQMP) to achieve compliance  with CAAQS.  These AQMP’s also serve as the basis for the preparation of the State  Implementation Plan (SIP) for the State of California.  Like the EPA, CARB also designates areas  within California as either attainment or nonattainment for each criteria pollutant based on  whether the CAAQS have been achieved.  Under the CCAA, areas are designated as  nonattainment for a pollutant if air quality data shows that a State standard for the pollutant  was violated at least once during the previous three calendar years.  Exceedances that are  affected by highly irregular or infrequent events are not considered violations of a State  standard, and are not used as a basis for designating areas as nonattainment.      BAY AREA AIR QUALITY MANAGEMENT DISTRICT    The Bay Area Air Quality Management District (BAAQMD) is the regional agency with  jurisdiction over the nine‐county region located in the Basin.  The Association of Bay Area  Governments (ABAG), the Metropolitan Transportation Commission (MTC), county  transportation agencies, cities and counties, and various nongovernmental organizations also  join in the efforts to improve air quality through a variety of programs.  These programs include  the adoption of regulations and policies, as well as implementation of extensive education and  public outreach programs.    The BAAQMD is responsible for attaining and/or maintaining air quality in the Basin within  Federal and State air quality standards.  Specifically, the BAAQMD has the responsibility to  monitor ambient air pollutant levels throughout the Basin and to develop and implement  strategies to attain the applicable Federal and State standards.    In June 2010, the BAAQMD adopted its updated California Environmental Quality Act (CEQA)  Air Quality Guidelines as a guidance document to provide lead government agencies,  consultants, and project proponents with uniform procedures for assessing air quality impacts  and preparing the air quality sections of environmental documents for projects subject to  CEQA.  The CEQA Air Quality Guidelines include methodologies and thresholds for addressing  project and program level air quality and GHG emissions.      In March 2010, the BAAQMD, in cooperation with the MTC and ABAG, published the draft  2010 Bay Area Clean Air Plan, which, supersedes the Bay Area 2005 Ozone Strategy.   The 2010 Bay  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 14 March 2011  Area Clean Air Plan updates the 2005 Ozone Strategy in accordance with the requirements of the  CCAA to achieve the following:    • Implement all feasible measures to reduce ozone; provide a control strategy to reduce  ozone, particulate matter, toxic air contaminants, and GHGs in a single, integrated plan;   • Review progress in improving air quality in recent years; and   • Establish emission control measures to be adopted or implemented in the 2010 to 2012  time frame.     The control strategy includes stationary‐source control measures to be implemented through  BAAQMD regulations; mobile‐source control measures to be implemented through incentive  programs and other activities; and transportation control measures to be implemented through  transportation programs in cooperation with the MTC, local governments, transit agencies, and  others.  The 2010 Bay Area Clean Air Plan also represents the Bay Area’s most recent triennial  assessment of the region’s strategy to attain the State one‐hour ozone standard.      GLOBAL CLIMATE CHANGE REGULATORY PROGRAMS     Federal    The FCAA requires the EPA to define national ambient air quality standards (national  standards) to protect public health and welfare in the United States.  The FCAA does not  specifically regulate GHG emissions; however, on April 2, 2007 the U.S. Supreme Court in  Massachusetts v. U.S. Environmental Protection Agency, determined that GHGs are pollutants that  can be regulated under the FCAA.  The EPA adopted an endangerment finding and cause or  contribute finding for GHGs on December 7, 2009.  Under the endangerment finding, the  Administrator found that the current and projected atmospheric concentrations of the six, key,  well‐mixed GHGs (CO2, CH4, N2O, HFCs, PFCs, and SF6) threaten the public health and welfare  of current and future generations.  Under the cause of contribute finding, the Administrator  found that the combined emissions of these well‐mixed GHGs from new motor vehicles and  new motor vehicle engines contribute to the GHG pollution which threatens public health and  welfare.    Based on these findings, on April 1, 2010, the EPA finalized the light‐duty vehicle rule  controlling GHG emissions.  This rule confirmed that January 2, 2011, is the earliest date that a  2012 model year vehicle meeting these rule requirements may be sold in the United States.  On  May 13, 2010, the EPA issued the final GHG Tailoring Rule.  This rule set thresholds for GHG  emissions that define when permits under the Prevention of Significant Deterioration and Title  V Operating Permit programs are required for new and existing industrial facilities.   Implementation of the Federal rules is expected to reduce the level of emissions from new  motor vehicles and large stationary sources.      Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 15 March 2011  State    Various statewide and local initiatives to reduce California’s contribution to GHG emissions  have raised awareness that, even though the various contributors to and consequences of global  climate change are not yet fully understood, global climate change is occurring, and that there is  a real potential for severe adverse environmental, social, and economic effects in the long term.   Every nation emits GHGs and as a result makes an incremental cumulative contribution to  global climate change; therefore, global cooperation will be required to reduce the rate of GHG  emissions enough to slow or stop the human‐caused increase in average global temperatures  and associated changes in climatic conditions.    Executive Order S‐1‐07.  Executive Order S‐1‐07 proclaims that the transportation sector is the  main source of GHG emissions in California, generating more than 40 percent of statewide  emissions.  It establishes a goal to reduce the carbon intensity of transportation fuels sold in  California by at least ten percent by 2020.  This order also directs CARB to determine whether  this Low Carbon Fuel Standard (LCFS) could be adopted as a discrete early‐action measure as  part of the effort to meet the mandates in AB 32.    Executive Order S‐3‐05.  Executive Order S‐3‐05 set forth a series of target dates by which  statewide emissions of GHGs would be progressively reduced, as follows:    • By 2010, reduce GHG emissions to 2000 levels;  • By 2020, reduce GHG emissions to 1990 levels; and  • By 2050, reduce GHG emissions to 80 percent below 1990 levels.    The Executive Order directed the secretary of the California Environmental Protection Agency  (Cal/EPA) to coordinate a multi‐agency effort to reduce GHG emissions to the target levels.  The  secretary will also submit biannual reports to the governor and California Legislature  describing the progress made toward the emissions targets, the impacts of global climate  change on California’s resources, and mitigation and adaptation plans to combat these impacts.   To comply with the executive order, the secretary of Cal/EPA created the California Climate  Action Team (CAT), made up of members from various State agencies and commissions.  The  team released its first report in March 2006.  The report proposed to achieve the targets by  building on the voluntary actions of California businesses, local governments, and communities  and through State incentive and regulatory programs.    Executive Order S‐13‐08.  Executive Order S‐13‐08 seeks to enhance the Stateʹs management of  climate impacts including sea level rise, increased temperatures, shifting precipitation, and  extreme weather events by facilitating the development of State’s first climate adaptation  strategy.  This will result in consistent guidance from experts on how to address climate change  impacts in the State of California.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 16 March 2011  Executive Order S‐14‐08.  Executive Order S‐14‐08 expands the Stateʹs Renewable Energy  Standard to 33 percent renewable power by 2020.  Additionally, Executive Order S‐21‐09  (signed on September 15, 2009) directs CARB to adopt regulations requiring 33 percent of  electricity sold in the State come from renewable energy by 2020.  CARB adopted the  “Renewable Electricity Standard” on September 23, 2010, which requires 33 percent renewable  energy by 2020 for most publicly owned electricity retailers.    Executive Order S‐20‐04.  Executive Order S‐20‐04, the California Green Building Initiative,  (signed into law on December 14, 2004), establishes a goal of reducing energy use in State‐ owned buildings by 20 percent from a 2003 baseline by 2015.  It also encourages the private  commercial sector to set the same goal.  The initiative places the California Energy Commission  (CEC) in charge of developing a building efficiency benchmarking system, commissioning and  retro‐commissioning (commissioning for existing commercial buildings) guidelines, and  developing and refining building energy efficiency standards under Title 24 to meet this goal.     Executive Order S‐21‐09.  Executive Order S‐21‐09, 33 percent Renewable Energy for California,  directs CARB to adopt regulations to increase Californiaʹs Renewable Portfolio Standard (RPS)  to 33 percent by 2020.  This builds upon SB 1078 (2002) which established the California RPS  program, requiring 20 percent renewable energy by 2017, and SB 107 (2006) which advanced the  20 percent deadline to 2010, a goal which was expanded to 33 percent by 2020 in the 2005  Energy Action Plan II.     Assembly Bill 32 (California Global Warming Solutions Act of 2006).  California passed the  California Global Warming Solutions Act of 2006 (AB 32; California Health and Safety Code  Division 25.5, Sections 38500 ‐ 38599).  AB 32 establishes regulatory, reporting, and market  mechanisms to achieve quantifiable reductions in GHG emissions and establishes a cap on  statewide GHG emissions.  AB 32 requires that statewide GHG emissions be reduced to 1990  levels by 2020.  AB 32 specifies that regulations adopted in response to AB 1493 should be used  to address GHG emissions from vehicles.  However, AB 32 also includes language stating that if  the AB 1493 regulations cannot be implemented, then CARB should develop new regulations to  control vehicle GHG emissions under the authorization of AB 32.    Assembly Bill 1493.  AB 1493 (also known as the Pavley Bill) requires that CARB develop and  adopt, by January 1, 2005, regulations that achieve “the maximum feasible reduction of GHG  emitted by passenger vehicles and light‐duty trucks and other vehicles determined by CARB to  be vehicles whose primary use is noncommercial personal transportation in the State.”    To meet the requirements of AB 1493, CARB approved amendments to the California Code of  Regulations (CCR) in 2004 by adding GHG emissions standards to California’s existing  standards for motor vehicle emissions.  Amendments to CCR Title 13, Sections 1900 and 1961  and adoption of 13 CCR Section 1961.1 require automobile manufacturers to meet fleet‐average  GHG emissions limits for all passenger cars, light‐duty trucks within various weight criteria,  and medium‐duty weight classes for passenger vehicles (i.e., any medium‐duty vehicle with a  gross vehicle weight rating less than 10,000 pounds that is designed primarily to transport  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 17 March 2011  people), beginning with the 2009 model year.  Emissions limits are reduced further in each  model year through 2016.  When fully phased in, the near‐term standards will result in a  reduction of about 22 percent in GHG emissions compared to the emissions from the 2002 fleet,  while the mid‐term standards will result in a reduction of about 30 percent.    Assembly Bill 3018.  AB 3018 established the Green Collar Jobs Council (GCJC) under the  California Workforce Investment Board (CWIB).  The GCJC will develop a comprehensive  approach to address California’s emerging workforce needs associated with the emerging green  economy.  This bill will ignite the development of job training programs in the clean and green  technology sectors.       Senate Bill 97.  SB 97, signed in August 2007 (Chapter 185, Statutes of 2007; PRC Sections  21083.05 and 21097), acknowledges that climate change is a prominent environmental issue that  requires analysis under CEQA.  This bill directs the Governor’s Office of Planning and Research  (OPR), which is part of the State Natural Resources Agency, to prepare, develop, and transmit  to CARB guidelines for the feasible mitigation of GHG emissions (or the effects of GHG  emissions), as required by CEQA.      OPR published a technical advisory recommending that CEQA lead agencies make a good‐faith  effort to estimate the quantity of GHG emissions that would be generated by a proposed  project.  Specifically, based on available information, CEQA lead agencies should estimate the  emissions associated with project‐related vehicular traffic, energy consumption, water usage,  and construction activities to determine whether project‐level or cumulative impacts could  occur, and should mitigate the impacts where feasible. OPR requested CARB technical staff to  recommend a method for setting CEQA thresholds of significance as described in CEQA  Guidelines Section 15064.7 that will encourage consistency and uniformity in the CEQA analysis  of GHG emissions throughout the State.    The Natural Resources Agency adopted the CEQA Guidelines Amendments prepared by OPR,  as directed by SB 97.  On February 16, 2010, the Office of Administration Law approved the  CEQA Guidelines Amendments, and filed them with the Secretary of State for inclusion in the  California Code of Regulations.  The CEQA Guidelines Amendments became effective on  March 18, 2010.      Senate Bill 375.  SB 375, signed in September 2008 (Chapter 728, Statutes of 2008), aligns regional  transportation planning efforts, regional GHG reduction targets, and land use and housing  allocation.  SB 375 requires Metropolitan Planning Organizations (MPOs) to adopt a sustainable  communities strategy (SCS) or alternative planning strategy (APS) that will prescribe land use  allocation in that MPOs regional transportation plan.  CARB, in consultation with MPOs, will  provide each affected region with reduction targets for GHGs emitted by passenger cars and  light trucks in the region for the years 2020 and 2035.  These reduction targets will be updated  every eight years but can be updated every four years if advancements in emissions  technologies affect the reduction strategies to achieve the targets.  CARB is also charged with  reviewing each MPO’s SCS or APS for consistency with its assigned targets.  If MPOs do not  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 18 March 2011  meet the GHG reduction targets, transportation projects may not be eligible for funding  programmed after January 1, 2012.    Senate Bills 1078 and 107.  SB 1078 (Chapter 516, Statutes of 2002) requires retail sellers of  electricity, including investor‐owned utilities and community choice aggregators, to provide at  least 20 percent of their supply from renewable sources by 2017.  SB 107 (Chapter 464, Statutes  of 2006) changed the target date to 2010.    Senate Bill 1368.  SB 1368 (Chapter 598, Statutes of 2006) is the companion bill of AB 32 and was  signed into law in September 2006.  SB 1368 required the California Public Utilities Commission  (CPUC) to establish a performance standard for baseload generation of GHG emissions by  investor‐owned utilities by February 1, 2007.  SB 1368 also required the CEC to establish a  similar standard for local publicly owned utilities by June 30, 2007.  These standards could not  exceed the GHG emissions rate from a baseload combined‐cycle, natural gas–fired plant.   Furthermore, the legislation states that all electricity provided to California, including imported  electricity, must be generated by plants that meet the standards set by CPUC and CEC.    CARB Scoping Plan    On December 11, 2008, CARB adopted its Scoping Plan, which functions as a roadmap to  achieve GHG reductions in California required by AB 32 through subsequently enacted  regulations.  CARB’s Scoping Plan contains the main strategies California will implement to  reduce CO2eq emissions by 174 million metric tons (MT), or approximately 30 percent, from the  State’s projected 2020 emissions level of 596 million MT CO2eq2  under a business as usual  (BAU)3  scenario.  This is a reduction of 42 million MT CO2eq, or almost ten percent, from 2002 to  2004 average emissions, but requires the reductions in the face of population and economic  growth through 2020.     CARB’s Scoping Plan calculates 2020 BAU emissions as the emissions that would be expected to  occur in the absence of any GHG reduction measures.  The 2020 BAU emissions estimate was  derived by projecting emissions from a past baseline year using growth factors specific to each  of the different economic sectors (e.g., transportation, electrical power, commercial and  residential, industrial, etc.).  CARB used three‐year average emissions, by sector, for 2002 to  2004 to forecast emissions to 2020.  At the time CARB’s Scoping Plan process was initiated, 2004  was the most recent year for which actual data was available.  The measures described in  CARB’s Scoping Plan are intended to reduce the projected 2020 BAU to 1990 levels, as required  by AB 32.  However, the San Francisco Superior Court has recently issued a tentative ruling,  that if issued as proposed, would suspend the implementation of the Scoping Plan pending  additional CEQA review.      2   Carbon Dioxide Equivalent (CO2eq) ‐ A metric measure used to compare the emissions from various  greenhouse gases based upon their global warming potential.  3   “Business as Usual” refers to emissions that would be expected to occur in the absence of GHG reductions.   See http://www.arb.ca.gov/cc/inventory/data/forecast.htm.  Note that there is significant controversy as to what BAU  means.  In determining the GHG 2020 limit, CARB used the above as the “definition.”  It is broad enough to allow for  design features to be counted as reductions. Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 19 March 2011  In Association of Irritated Residents, et al. v. California Air Resources Board, et al., the Superior  Court of California for the County of San Francisco (Superior Court) issued a ʺtentative  statement of decisionʺ (Tentative Decision) that prevents CARB from implementing a state‐wide  GHG regulatory program under AB 32 until the agency complies with the requirements of  CEQA.  The Tentative Decision partially grants a petition for a writ of mandate brought by a  coalition of environmental justice organizations (Petitioners) that alleged that CARBʹs Scoping  Plan violated both AB 32 and CEQA.  Although the Superior Court denied all claims related to  AB 32, the court found that CARB: 1) failed to adequately discuss and analyze the impacts of  alternatives in its proposed Scoping Plan as required by its CEQA implementing regulations;  and 2) improperly approved the Scoping Plan prior to completing the environmental review  required by CEQA.  In upholding the Petitionersʹ challenge on these two CEQA issues, the  Superior Court issued a Peremptory Writ of Mandate and enjoined CARB from further  implementation of the Scoping Plan until it complies with all CEQA requirements.  Parties to  the case had 15 days from the issuance of the Tentative Decision to file objections before the  Superior Court issued a final decision in the case.      On March 18, 2011, the Superior Court issued its Final Statement of Decision, which is  substantially similar to the Tentative Decision.  The Superior Court ruled in favor of CARB  concerning AB 32 mandates and how to best reach the GHG reduction goals set by AB 32.   However, the Superior Court determined that CARB failed to conduct adequate CEQA review  for the Scoping Plan.  Specifically, the Superior Court concluded that CARB failed to consider  adequate alternatives to the mix of measures adopted in the Scoping Plan, including especially  alternatives to cap‐and‐trade measures, and that CARB improperly began implementing the  Scoping Plan measures before its CEQA review process was complete.  Therefore, the Superior  Court has suspended any further implementation of the measures contained in the Scoping  Plan until the State has complied with CEQA.        2.3 SENSITIVE RECEPTORS    Sensitive populations are more susceptible to the effects of air pollution than is the general  population.  Sensitive populations (sensitive receptors) that are in proximity to localized  sources of toxics and CO are of particular concern.  Land uses considered sensitive receptors  include residences, schools, playgrounds, childcare centers, long‐term health care facilities,  rehabilitation centers, convalescent centers, and retirement homes.  Table 2, Sensitive Receptors,  lists the distances and locations of sensitive receptors within the project vicinity.      Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 20 March 2011  Table 2  Sensitive Receptors  Type Name Distance from Project Site (feet) Direction from Project Site 475 North 875 Northeast 230 East 1,660 Southeast Adjoining East/South 1,200 South 900 Southwest 130 West Residential Residential Uses 600 Northwest Schools Yavneh Day School 820 Southeast Los Gatos Swim and Racquet Club 1,000 East Parks/Recreation Courtside Club 350 Southwest Addison Penzack Jewish Community Center 820 Southeast First Assembly of God 1,400 South Places of Worship Congregation Tsemach Adonai 1,450 South Hospitals El Camino Hospital Los Gatos 1,900 Northwest Source: Google Earth 2010.

Air Quality & Greenhouse Gas Assessment 22 March 2011  CARBON MONOXIDE (CO)      CO is an odorless, colorless toxic gas that is emitted by mobile and stationary sources as a result  of incomplete combustion of hydrocarbons or other carbon‐based fuels.  In cities, automobile  exhaust can cause as much as 95 percent of all CO emissions.  At high concentrations, CO can  reduce the oxygen‐carrying capacity of the blood and cause headaches, dizziness, and  unconsciousness.      OZONE (O3)      O3 occurs in two layers of the atmosphere.  The layer surrounding the earthʹs surface is the  troposphere.  The troposphere extends approximately 10 miles above ground level, where it  meets the second layer, the stratosphere.  The stratospheric (the “good” ozone) layer extends  upward from about ten to 30 miles and protects life on earth from the sunʹs harmful ultraviolet  rays (UV‐B).  “Bad” ozone is a photochemical pollutant, and needs VOCs, NOX and sunlight to  form.  Therefore, VOCs and NOX are ozone precursors.  VOCs and NOX are emitted from  various sources throughout the Town.  Significant ozone formation generally requires an  adequate amount of precursors in the atmosphere and several hours in a stable atmosphere  with strong sunlight.  High ozone concentrations can form over large regions when emissions  from motor vehicles and stationary sources are carried hundreds of miles from their origins.      Many respiratory ailments, as well as cardiovascular disease, are aggravated by exposure to  high O3 levels.  O3 also damages natural ecosystems (such as forests and foothill plant  communities) and damages agricultural crops and some man‐made materials (such as rubber,  paint and plastics).  Societal costs from ozone damage include increased healthcare costs, the  loss of human and animal life, accelerated replacement of industrial equipment and reduced  crop yields.      NITROGEN DIOXIDE (NO2)    NOX are a family of highly reactive gases that are a primary precursor to the formation of  ground‐level O3, and react in the atmosphere to form acid rain.  NO2 (often used  interchangeably with NOX) is a reddish‐brown gas that can cause breathing difficulties at high  levels.  Peak readings of NO2 occur in areas that have a high concentration of combustion  sources (e.g., motor vehicle engines, power plants, refineries, and other industrial operations).  NO2 can irritate and damage the lungs, and lower resistance to respiratory infections such as  influenza.  The health effects of short‐term exposure are still unclear.  However, continued or  frequent exposure to NO2 concentrations that are typically much higher than those normally  found in the ambient air may increase acute respiratory illnesses in children and increase the  incidence of chronic bronchitis and lung irritation.  Chronic exposure to NO2 may aggravate  eyes and mucus membranes and cause pulmonary dysfunction.        Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 23 March 2011  COARSE PARTICULATE MATTER (PM10)      PM10 refers to suspended particulate matter, which is smaller than ten microns or ten one‐ millionths of a meter.  PM10 arises from sources such as road dust, diesel soot, combustion  products, construction operations, and dust storms.  PM10 scatters light and significantly  reduces visibility.  In addition, these particulates penetrate the lungs and can potentially  damage the respiratory tract.  On June 19, 2003, CARB adopted amendments to the statewide  24‐hour particulate matter standards based upon requirements set forth in the Children’s  Environmental Health Protection Act (SB 25).      FINE PARTICULATE MATTER (PM2.5)      Due to recent increased concerns over health impacts related to fine particulate matter  (particulate matter 2.5 microns in diameter or less), both State and Federal PM2.5 standards have  been created.  Particulate matter impacts primarily affect infants, children, the elderly, and  those with pre‐existing cardiopulmonary disease.  In 1997, the EPA announced new PM2.5  standards.  Industry groups challenged the new standard in court and the implementation of  the standard was blocked.  However, upon appeal by the EPA, the U.S. Supreme Court  reversed this decision and upheld the EPA’s new standards.      On June 20, 2002, CARB adopted amendments for statewide annual ambient particulate matter  air quality standards.  These standards were revised/established due to increasing concerns by  CARB that previous standards were inadequate, as almost everyone in California is exposed to  levels at or above the current State standards during some parts of the year, and the statewide  potential for significant health impacts associated with particulate matter exposure was  determined to be large and wide‐ranging.      VOLATILE ORGANIC COMPOUNDS (VOCs or Reactive Organic Gases [ROG])     Hydrocarbons are organic gases that are formed solely of hydrogen and carbon.  There are  several subsets of organic gases including ROGs and VOCs.  Both ROGs and VOCs are emitted  from the incomplete combustion of hydrocarbons or other carbon‐based fuels.  The major  sources of hydrocarbons are combustion engine exhaust, oil refineries, and oil‐fueled power  plants; other common sources are petroleum fuels, solvents, dry cleaning solutions, and paint  (via evaporation).    LEAD (Pb)      In the Basin, atmospheric lead is generated almost entirely by the combustion of leaded gasoline  and contributes less than one percent of the material collected as total suspended particulate.   Atmospheric lead concentrations have been reduced substantially in recent years due to the  lowering of average lead content in gasoline.  Exceedances of the State air quality standard for  lead (monthly average concentration of 1.50 μg/m3 ) now are confined to densely populated  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 24 March 2011  areas, where vehicle traffic is greatest.  Lead was not monitored at the nearby monitoring  locations.  The Basin has achieved attainment for lead under both State and Federal standards.      GLOBAL CLIMATE CHANGE GASES The natural process through which heat is retained in the troposphere is called the “greenhouse  effect.”4   The greenhouse effect traps heat in the troposphere through a three‐fold process,  summarized as follows:  short wave radiation emitted by the Sun is absorbed by the Earth; the  Earth emits a portion of this energy in the form of long wave radiation; and GHGs in the upper  atmosphere absorb this long wave radiation and emit this long wave radiation into space and  toward the Earth.  This “trapping” of the long wave (thermal) radiation emitted back toward  the Earth is the underlying process of the greenhouse effect.      The most abundant GHGs are water vapor and carbon dioxide.  Many other trace gases have  greater ability to absorb and re‐radiate long wave radiation; however, these gases are not as  plentiful.  For this reason, and to gauge the potency of GHGs, scientists have established a  Global Warming Potential (GWP) for each GHG based on its ability to absorb and re‐radiate  long wave radiation.  The GWP of a gas is determined using carbon dioxide as the reference gas  with a GWP of one (1).    GHGs normally associated with the proposed project include the following:5     • Water Vapor (H2O).  Although water vapor has not received the scrutiny of other  GHGs, it is the primary contributor to the greenhouse effect.  Natural processes, such  as evaporation from oceans and rivers, and transpiration from plants, contribute 90  percent and 10 percent of the water vapor in our atmosphere, respectively.  The  primary human related source of water vapor comes from fuel combustion in motor  vehicles; however, this is not believed to contribute a significant amount (less than  one percent) to atmospheric concentrations of water vapor.  The Intergovernmental  Panel on Climate Change (IPCC) has not determined a GWP for water vapor.  • Carbon Dioxide (CO2).  CO2 is primarily generated by fossil fuel combustion in  stationary and mobile sources.  Due to the emergence of industrial facilities and  mobile sources in the past 250 years, the concentration of CO2 in the atmosphere has  increased 36 percent.6  CO2 is the most widely emitted GHG and is the reference gas  (GWP of 1) for determining GWPs for other GHGs.    4  The troposphere is the bottom layer of the atmosphere, which varies in height from the Earth’s surface to 10  to 12 kilometers.  5  All Global Warming Potentials are given as 100 year GWP. Unless noted otherwise, all Global Warming  Potentials were obtained from the Intergovernmental Panel on Climate Change. Climate Change (Intergovernmental  Panel on Climate Change, Climate Change, The Science of Climate Change – Contribution of Working Group I to the Second  Assessment Report of the IPCC, 1996).  6

Air Quality & Greenhouse Gas Assessment 25 March 2011  • Methane (CH4).  CH4 is emitted from biogenic sources, incomplete combustion in  forest fires, landfills, manure management, and leaks in natural gas pipelines.  In the  United States, the top three sources of CH4 are landfills, natural gas systems, and  enteric fermentation.  CH4 is the primary component of natural gas, which is used for  space and water heating, steam production, and power generation.  The GWP of CH4  is 21.  • Nitrous Oxide (N2O).  N2O is produced by both natural and human related sources.   Primary human related sources include agricultural soil management, animal  manure management, sewage treatment, mobile and stationary combustion of fossil  fuel, adipic acid production, and nitric acid production.  The GWP of N2O is 310.  • Hydrofluorocarbons (HFCs).  HFCs are typically used as refrigerants for both  stationary refrigeration and mobile air conditioning.  The use of HFCs for cooling  and foam blowing is growing, as the continued phase out of chlorofluorocarbons  (CFCs) and hydrochlorofluorocarbons (HCFCs) gains momentum.  The GWP of  HFCs range from 140 for HFC‐152a to 11,700 for HFC‐23.7   • Perfluorocarbons (PFCs).  PFCs are compounds consisting of carbon and fluorine.   They are primarily created as a byproduct of aluminum production and semi  conductor manufacturing.  PFCs are potent GHGs with a GWP several thousand  times that of CO2, depending on the specific PFC.  Another area of concern regarding  PFCs is their long atmospheric lifetime (up to 50,000 years).8   The GWP of PFCs  range from 6,500 to 9,200.  • Sulfur hexafluoride (SF6).  SF6 is a colorless, odorless, nontoxic, nonflammable gas.  It  is most commonly used as an electrical insulator in high voltage equipment that  transmits and distributes electricity.  SF6 is the most potent GHG that has been  evaluated by the Intergovernmental Panel on Climate Change with a GWP of 23,900.   However, its global warming contribution is not as high as the GWP would indicate  due to its low mixing ratio compared to carbon dioxide (4 parts per trillion [ppt] in  1990 versus 365 parts per million [ppm], respectively).9     In addition to the six major GHGs discussed above (excluding water vapor), many other  compounds have the potential to contribute to the greenhouse effect.  Some of these substances  were previously identified as stratospheric O3 depletors; therefore, their gradual phase out is  currently in effect.  The following is a listing of these compounds:    • Hydrochlorofluorocarbons (HCFCs).  HCFCs are solvents, similar in use and chemical  composition to CFCs.  The main uses of HCFCs are for refrigerant products and air  conditioning systems.  As part of the Montreal Protocol, all developed countries that  adhere to the Montreal Protocol are subject to a consumption cap and gradual phase  out of HCFCs.  The United States is scheduled to achieve a 100 percent reduction to  7

1,1,1 trichloroethane.  1,1,1 trichloroethane or methyl chloroform is a solvent and  degreasing agent commonly used by manufacturers.  The GWP of methyl  chloroform is 110 times that of CO2.11   • Chlorofluorocarbons (CFCs).  CFCs are used as refrigerants, cleaning solvents, and  aerosols spray propellants.  CFCs were also part of the U.S. Environmental  Protection Agency’s (EPA) Final Rule (57 FR 3374) for the phase out of O3 depleting  substances.  Currently, CFCs have been replaced by HFCs in cooling systems and a  variety of alternatives for cleaning solvents.  Nevertheless, CFCs remain suspended  in the atmosphere contributing to the greenhouse effect.  CFCs are potent GHGs  with GWPs ranging from 4,600 for CFC 11 to 14,000 for CFC 13.12   10  U.S. Environmental Protection Agency, Protection of Stratospheric Ozone: Listing of Global Warming Potential for

Under CEQA, the BAAQMD is a commenting responsible agency on air quality within its  jurisdiction or impacting its jurisdiction.  The BAAQMD reviews projects to ensure that they  would: (1) support the primary goals of the latest Air Quality Plan; (2) include applicable  control measures from the Air Quality Plan; and (3) not disrupt or hinder implementation of  any Air Quality Plan control measures.    As described above, the BAAQMD adopted their CEQA Air Quality Guidelines to assist lead  agencies in evaluating air quality impacts of projects and plans proposed in the Basin.  The  CEQA Air Quality Guidelines provide BAAQMD‐recommended procedures for evaluating  potential air quality and GHG impacts during the environmental review process consistent with  CEQA requirements.  In addition to providing new thresholds for GHG emissions, the 2010  CEQA Air Quality Guidelines provide updated significance thresholds for criteria pollutants and  supersede the BAAQMD’s previous CEQA guidance titled BAAQMD CEQA Guidelines:  Assessing the Air Quality Impacts of Projects and Plans (1999).    If the project proposes development in excess of the established thresholds, as illustrated in  Table 4, BAAQMD Emission Thresholds, a significant air quality impact may occur and additional  analysis is warranted to fully assess the significance of impacts.      Table 4

The BAAQMD does not have an adopted threshold of significance for construction‐related  GHG emissions.  However, the BAAQMD CEQA Air Quality Guidelines recommend  quantification and disclosure of construction GHG emissions.  The BAAQMD also recommends  that the Lead Agency should make a determination on the significance of these construction  generated GHG emission impacts in relation to meeting AB 32 GHG reduction goals, as  required by the Public Resources Code, Section 21082.2.  The Lead Agency is encouraged to

The environmental analysis in this section is patterned after the Initial Study Checklist  recommended by the CEQA Guidelines, as amended.  The issues presented in the Initial Study  Checklist have been utilized as thresholds of significance in this section.  Accordingly, a project  may create a significant environmental impact if it causes one or more of the following to occur:    • Conflict with or obstruct implementation of the applicable air quality plan (refer to  Impact Statement AQ‐1);   • Violate any air quality standard or contribute substantially to an existing or projected air  quality violation (refer to Impact Statement AQ‐2);   • Result in a cumulatively considerable net increase of any criteria pollutant for which the  project region is in nonattainment under an applicable Federal or State ambient air  quality standard (including releasing emissions that exceed quantitative thresholds for  O3 precursors) (refer to Impact Statement AQ‐3);   • Expose sensitive receptors to substantial pollutant concentrations (refer to Impact  Statement AQ‐4);   • Create objectionable odors affecting a substantial number of people (refer to Impact  Statement AQ‐5);  • Generate greenhouse gas emissions, either directly or indirectly, that may have a  significant impact on the environment (refer to Impact Statement GHG‐1); and/or  • Conflict with an applicable plan, policy or regulation adopted for the purpose of  reducing the emissions of greenhouse gases (refer to Impact Statement GHG‐2).    Based on these standards and thresholds, the effects of the proposed project have been  categorized as either a “less than significant impact” or a “potentially significant impact.”   Mitigation measures are recommended for potentially significant impacts.      AQ‐1 CONFLICT WITH OR OBSTRUCT IMPLEMENTATION OF THE  APPLICABLE AIR QUALITY PLAN?    Level of Significance Before Mitigation:  Potentially Significant.     Scenario 1    The most recently adopted air quality plan in the Basin is the 2010 Bay Area Clean Air Plan (Clean  Air Plan).  This Clean Air Plan outlines how the San Francisco Bay Area will attain air quality  standards, reduce population exposure and protect public health, and reduce GHG emissions.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 31 March 2011  Scenario 1 proposes to remove and replace existing buildings (which currently total 250,000 s.f.)  with 550,000 s.f. of office development (net total of 300,000 s.f.).         The Town’s General Plan designates the project site as Office/Professional and Light Industrial.   The project would not conflict with the Town’s General Plan designations.  The  Office/Professional designation allows for professional and business offices, and the Light  Industrial designation allows for large‐scale office development and well‐controlled research  and development uses.  As indicated in the analysis below, the proposed project would not  result in significant long‐term operational air quality impacts regarding ROG, NOX, and PM  emissions.  Additionally, the project would incorporate transportation demand management  features (included as project design features required by Mitigation Measure GHG‐1) that  would be consistent with those of the Clean Air Plan.  Construction‐related air quality impacts  would be reduced to less than significant levels with implementation of Mitigation Measures  AQ‐1 through AQ‐3.  Therefore, the project would not hinder the region’s ability achieve  compliance with the State ozone standards.  Therefore, the proposed project would not conflict  with the Clean Air Plan, and impacts would be less than significant.     Scenario 2    Similar to Scenario 1, the development of Scenario 2 would result in commercial office space at  the project site.  Scenario 2 would not conflict with the Town’s General Plan designations.   Scenario 2 would not result in significant long‐term operational air quality impacts regarding  ROG, NOX, and PM emissions.  Additionally, the project would incorporate transportation  demand management features (included as project design features required by Mitigation  Measure GHG‐1) that would be consistent with those of the Clean Air Plan.  Construction‐ related air quality impacts would be reduced to less than significant levels with implementation  of Mitigation Measures AQ‐1 through AQ‐3.  Therefore, as with Scenario 1, Scenario 2 would  not conflict with the Clean Air Plan, and impacts would be less than significant.     Scenario 3    The development of Scenario 3 would result in less commercial office space than considered  under Scenario 1.  However, Scenario 3 also includes up to 516 high‐density units.  Scenario 3  would not conflict with the Town’s General Plan designations.  Also, Scenario 3 would not result  in significant long‐term operational air quality impacts regarding ROG, NOX, and PM  emissions.  Construction‐related air quality impacts would be reduced to less than significant  levels with implementation of Mitigation Measures AQ‐1 through AQ‐3.  Therefore, as with  Scenario 1, Scenario 3 would not conflict with the Clean Air Plan, and impacts would be less  than significant.     Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 32 March 2011  Scenario 4    The development of Scenario 4 would result in a similar development plan as Scenario 3;  however, Scenario 4 proposes 600 senior units instead of 516 high‐density units.  Scenario 4  would not conflict with the Town’s General Plan designations.  Also, Scenario 4 would not result  in significant long‐term operational air quality impacts regarding ROG, NOX, and PM  emissions.  Construction‐related air quality impacts would be reduced to less than significant  levels with implementation of Mitigation Measures AQ‐1 through AQ‐3.  Therefore, as with  Scenario 1, Scenario 4 would not conflict with the Clean Air Plan, and impacts would be less  than significant.       Mitigation Measures:  Refer to Mitigation Measures AQ‐1 through AQ‐3, GHG‐1.    Level of Significance After Mitigation:  Less Than Significant.    AQ‐2 VIOLATE ANY AIR QUALITY STANDARD OR CONTRIBUTE  SUBSTANTIALLY TO AN EXISTING OR PROJECTED AIR QUALITY  VIOLATION?    Level of Significance Before Mitigation: Potentially Significant.      SHORT‐TERM EMISSIONS    Scenario 1    Short‐term air quality impacts are predicted to occur during demolition, grading and  construction operations associated with implementation of the proposed project.  Temporary air  emissions would result from the following activities:    • Particulate (fugitive dust) emissions from demolition, grading, and building  construction; and  • Exhaust emissions from the construction equipment and the motor vehicles of the  construction crew.    Potential odors could arise from the diesel construction equipment used on‐site, as well as from  architectural coatings and asphalt off‐gassing.  Odors generated during construction activities  would be temporary and are not considered to be a significant impact.  Emissions produced  during demolition, grading, and construction activities are short‐term, as they would exist only  during construction.    Construction activities for the proposed project would include demolition, grading, trenching,  construction of buildings, paving, and architectural coatings.  Project construction would result  in approximately 1.61 acres of site grading per day with up to 2,730 cubic yards per day of cut  and fill during mass grading.  Grading for the site would require the export of 95,500 cubic  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 33 March 2011  and fill during mass grading.  Grading for the site would require the export of 95,500 cubic  yards.  The analysis of daily construction emissions has been prepared utilizing the URBEMIS  2007 computer model; refer to Appendix A, Air Modeling Data.  Table 6, Construction Emissions,  presents the anticipated daily short‐term construction emissions.  Where emissions exceed the  BAAQMD thresholds, the Basic mitigation measures required by the BAAQMD have been  analyzed and quantified.  Should emissions still exceed the BAAQMD thresholds, enhanced

The reduction/credits for construction emission mitigations are based on mitigation included in the URBEMIS2007 version 9.2.4 computer model and as typically required by the BAAQMD (Basic Control Measures and Regulation 6: Particulate Matter and Visible Emissions). The mitigation includes the following: replace ground cover on disturbed areas quickly, water exposed surfaces twice daily, and proper loading/unloading of mobile and other construction equipment. 2. Enhanced Mitigation involves compliance with an additional control measure requiring the use of low volatile organic compound (VOC) coatings (compliance with BAAQMD Regulation 8, Rule 3; Architectural Coatings). Specifically, the VOX content in coatings shall not exceed 150 grams per liter. 3. Enhanced Mitigation accounts for the VMT reduction during soil hauling, as required by Mitigation Measure AQ-3. 4. Phase 1 and Phase 2 would have construction activities occurring in Year 2. However, the construction activities in each phase would not overlap. Therefore, the maximum daily emissions occurring in Year 2 are reported. Refer to Appendix A, Air Modeling Data, for assumptions used in this analysis.     Fugitive Dust Emissions    Construction activities are a source of fugitive dust (also known as PM10 and PM2.5) emissions  that may have a substantial, temporary impact on local air quality.  Fugitive dust is often a  nuisance to those living and working within the vicinity of the project site.  Fugitive dust  emissions are associated with demolition, land clearing, ground evacuation, cut and fill  operations, and truck travel on unpaved roadways.  Fugitive dust emissions also vary  substantially from day to day, depending on the level of activity, the specific operations, and  weather conditions.   Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 35 March 2011  PM10 and PM2.5 are both emitted during construction activities and as a result of wind erosion  over exposed soil surfaces.  Clearing and grading activities comprise the major sources of  construction dust emissions, but traffic and general disturbance of the soil also generates  significant dust emissions.  PM10 and PM2.5 emissions can vary greatly depending on the level of  activity, the specific operations taking place, the equipment being operated, local soils, weather  conditions, and other factors making quantification difficult.  The highest potential for  construction dust impacts would occur during the dry late spring, summer, and early fall  months when soils are dry.  Despite this variability in emissions, experience has shown that  there are a number of feasible control measures that can be reasonably implemented to  significantly reduce PM10 and PM2.5 emissions from construction activities.  The BAAQMD  recommends the implementation of all Basic Construction Mitigation Measures, whether or not  construction‐related emissions exceed applicable significance thresholds.  As shown in Table 6,  above, unmitigated fugitive dust emissions would exceed the BAAQMD thresholds for PM10  and PM2.5.  However, implementation of the BAAQMD’s Basic Construction Mitigation  Measures would be required for the proposed project; refer to Mitigation Measure AQ‐1.   Implementation of the BAAQMD Basic Construction Mitigation (included in Mitigation  Measure AQ‐1) would reduce fugitive dust impacts to a less than significant level.       ROG Emissions     In addition to gaseous and particulate emissions, the application of asphalt and surface coatings  creates ROG emissions, which are O3 precursors.  In accordance with the methodology  prescribed by the BAAQMD, the ROG emissions associated with paving have been quantified  with the URBEMIS 2007 model.  In addition, based upon the size of the buildings, architectural  coatings were also quantified within the URBEMIS 2007 model.     The highest concentration of ROG emissions would be generated during the application of  architectural coatings towards the end of construction.  As required by law, all architectural  coatings for the proposed project structures would comply with BAAQMD Regulation 8, Rule 3:  Architectural Coating.  Regulation 8, Rule 3 provides specifications on painting practices as well  as regulates the ROG content of paint.  As indicated in Table 6, the project construction would  result in an exceedance of ROG emissions and compliance with BAAQMD Additional Control  Measures to reduce ROG emissions is required.  Specifically, the VOC content for coatings shall  not exceed 150 grams per liter.  Therefore, implementation of Mitigation Measure AQ‐2  (compliance with BAAQMD Additional Control Measures [i.e., Regulation 8, Rule 3]) would be  required to reduce ROG emissions from architectural coatings.  With implementation of  Mitigation Measures AQ‐2, impacts would be reduced to a less than significant level.     Construction Equipment and Worker Vehicle Exhaust    Exhaust emission factors for typical diesel‐powered heavy equipment are based on the  URBEMIS 2007 program defaults.  Variables factored into estimating the total construction  emissions include: level of activity, length of construction period, number of pieces/types of  equipment in use, site characteristics, weather conditions, number of construction personnel,  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 36 March 2011  and the amount of materials to be transported on‐site or off‐site.  A listing of mobile and  stationary construction equipment is included in Appendix A, Air Modeling Data.      Exhaust emissions from construction activities include emissions associated with the transport  of machinery and supplies to and from the project site, emissions produced on‐site as the  equipment is used, and emissions from trucks transporting materials to and from the site.   Emitted pollutants would include ROG, NOX, PM10, and PM2.5.  Thresholds for ROG, PM10, and  PM2.5 would not be exceeded by exhaust emissions (note that exhaust emissions are included in  total ROG, PM10, and PM2.5 emissions in Table 6), as the majority of these emissions are  attributed to fugitive dust and architectural coatings.  However, due to the amount of soil  hauling required for the proposed project, NOX thresholds would be exceeded in all three  construction phases.  Therefore, implementation of Mitigation Measure AQ‐3 would limit the  vehicle miles traveled (VMT) from soil hauling trucks during grading to ensure NOX emissions  would not exceed the BAAQMD thresholds.  As indicated in Table 6, NOX emissions would be  less than significant with implementation of Mitigation Measure AQ‐3.     Naturally Occurring Asbestos    Pursuant to guidance issued by the Governor’s Office of Planning and Research, State  Clearinghouse, Lead Agencies are encouraged to analyze potential impacts related to naturally  occurring asbestos.  Naturally occurring asbestos can be released from serpentinite and  ultramafic rocks when the rock is broken or crushed.  At the point of release, the asbestos fibers  may become airborne, causing air quality and human health hazards.  These rocks have been  commonly used for unpaved gravel roads, landscaping, fill projects, and other improvement  projects in some localities.  Asbestos may be released to the atmosphere due to vehicular traffic  on unpaved roads, during grading for development projects, and at quarry operations.    Serpentinite and/or ultramafic rock are known to be present in 44 of Californiaʹs 58 counties.   These rocks are particularly abundant in the counties associated with the Sierra Nevada  foothills, the Klamath Mountains, and Coast Ranges.  According to the Department of  Conservation Division of Mines and Geology, A General Location Guide for Ultramafic Rocks in  California – Areas More Likely to Contain Naturally Occurring Asbestos Report (August 2000), the  project site is not located in an area where naturally occurring asbestos is likely to be present.   Therefore, impacts are less than significant in this regard.    Structural Asbestos    Asbestos is a strong, incombustible, and corrosion resistant material, which was used in many  commercial products since prior to the 1940s and up until the early 1970s.  If inhaled, asbestos  fibers can result in serious health problems.  Asbestos Containing Materials (ACMs) are  building materials containing more than one percent asbestos (some state and regional  regulators impose a one‐tenth of one percent threshold).  Multiple on‐site structures requiring  demolition exist within the boundaries of the project site; therefore, the potential for ACMs to  be found on‐site is considered likely.  The BAAQMD regulates the demolition of buildings and  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 37 March 2011  structures containing asbestos.  On‐site demolition activities would be conducted in accordance  with BAAQMD Regulation 11, Rule 2 (Asbestos Demolition, Renovation and Manufacturing).        Total Daily Construction Emissions    In accordance with the BAAQMD Guidelines, URBEMIS 2007 was utilized to model  construction emissions for ROG, NOX, PM10, and PM2.5.  Construction would occur over a five  year period, with the greatest amount of fugitive dust emissions being generated during the  initial stages of each construction phase.  Additionally, the greatest amount of ROG emissions  would typically occur during the final stages of each construction phase due to the application  of architectural coatings.      The URBEMIS 2007 model allows the user to input mitigation measures such as watering the  construction area to limit fugitive dust in the project area.  Mitigation measures inputted within  the URBEMIS 2007 model allow for certain reduction credits and result in a decrease of  pollutant emissions.  Reduction credits are based upon various land use and transportation  studies and were programmed within the URBEMIS 2007 model.13   As indicated in Table 6, the  URBEMIS 2007 model calculates the reduction associated with recommended mitigation  measures for ROG.  With the implementation of Mitigation Measures AQ‐1 through AQ‐3  construction‐related impacts would be less than significant.    LONG‐TERM EMISSIONS    Operational emissions generated by both stationary and mobile sources would result from  normal daily activities on the project site after occupation (i.e., increased loads of O3, PM10, and  CO).  Stationary area source emissions would be generated by the consumption of natural gas  for space and water heating devices, the operation of landscape maintenance equipment, and  the use of consumer products.  Mobile emissions would be generated by the motor vehicles  traveling to and from the project site.  Emissions associated with each of these sources were  calculated and are discussed below.     Scenario 1    Mobile Source Emissions    Mobile sources are emissions from motor vehicles, including tailpipe and evaporative  emissions.  Depending upon the pollutant being discussed, the potential air quality impact may  be of either regional or local concern.  For example, ROG, NOX, SOX, PM10, and PM2.5 are all  pollutants of regional concern (NOX and ROG react with sunlight to form O3 [photochemical  smog], and wind currents readily transport SOX, PM10, and PM2.5).  However, CO tends to be a  localized pollutant, dispersing rapidly at the source.      13  Jones and Stokes Associates, Software User’s Guide: URBEMIS2007 for Windows User’s Guide Appendices,  November 2007.  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 38 March 2011  Project‐generated vehicle emissions have been estimated using the URBEMIS 2007 model.  This  model predicts ROG, NOX, PM10, and PM2.5 emissions from motor vehicle traffic associated with  new or modified land uses; refer to Appendix A, Air Modeling Data.  According to the project’s  Traffic Impact Analysis, the proposed project would generate a net 3,126 daily trips.  Table 7,  Long‐Term Operational Air Emissions presents the anticipated mobile source emissions.  As  shown in Table 7, emissions generated by vehicle traffic associated with the proposed project  would not exceed established BAAQMD thresholds for ROG, NOX, and PM10.  Therefore,  impacts from vehicle emissions would be less than significant.     Table 7  Long‐Term Operational Air Emissions    Pollutant (lbs/day)1 Project Emissions ROG NOX PM10 PM2.5 Area Source Emissions 2.03

No No No No ROG = reactive organic gases; NOX = nitrogen oxides; CO = carbon monoxide; SO2 = sulfur dioxide; PM10 = particulate matter; less than 10 microns; PM2.5 = particulate matter; less than 2.5 microns; lbs/day = pounds per day. Notes: 1. Based on URBEMIS 2007 modeling results, worst-case seasonal emissions for area and mobile emissions have been modeled.     Area Source Emissions    Area source emissions would be generated due to an increased demand for electrical energy  and natural gas with the development of the proposed project.  This assumption is based on the  supposition that those power plants supplying electricity to the site are utilizing fossil fuels.   Electric power generating plants are distributed throughout the Basin and western United  States, and their emissions contribute to the total regional pollutant burden.  The primary use of  natural gas by the proposed land uses would be for combustion to produce space heating, water  heating, other miscellaneous heating, or air conditioning, consumer products, and landscaping.   As indicated in Table 7, area source emissions from the proposed project would not exceed  BAAQMD thresholds.  If stationary sources, such as backup generators, are installed on‐site,  they would be required to obtain the applicable permits from BAAQMD for operation of such  equipment.  The BAAQMD is responsible for issuing permits for the operation of stationary  sources in order to reduce air pollution, and to attain and maintain the national and California  ambient air quality standards in the Basin.  Newly modified or constructed stationary sources  subject to BAAQMD permitting may be required to implement Best Available Control  Technology (BACT), which may include the installation of emissions control equipment or the  implementation of administrative practices that would result in the lowest achievable emission  rate.  Backup generators would be used only in emergency situations, and would not contribute  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 39 March 2011  a substantial amount of emissions capable of exceeding BAAQMD thresholds.  Thus, impacts  from area source emissions would be less than significant.    Scenario 2    The development of Scenario 2 would result in less commercial office space than considered  under Scenario 1.  Construction related air quality impacts would be reduced due to the  reduction in required construction activities.  However, Mitigation Measures AQ‐1 through  AQ‐3 would still be required to ensure construction air emissions are reduced to less than the  BAAQMD thresholds.  It is noted that Mitigation Measure AQ‐1 is required by the BAAQMD,  and Mitigation Measures AQ‐2 and AQ‐3 have been formulated based upon the “worst case”  construction scenario (Scenario 1).  Therefore, although emissions are expected to be less under  Scenario 2, implementation of Mitigation Measures AQ‐2 and AQ‐3 would ensure emissions are  reduced below BAAQMD thresholds.  As with Scenario 1, impacts would be less than  significant with the incorporation of the recommended construction mitigation.    At full development, Scenario 2 would result in 948 daily net new trips (as opposed to 3,126 for  Scenario 1).  Therefore, as the majority of operational emissions are attributed to mobile sources,  Scenario 2 would result in fewer emissions than Scenario 1 (which do not exceed the BAAQMD  thresholds).  As with Scenario 1, operational impacts under Scenario 2 would be less than  significant.      Scenario 3    The development of Scenario 3 would result in less commercial office space than considered  under Scenario 1.  However, Scenario 3 also includes up to 516 high‐density units.  Construction  related air quality impacts would be similar to that presented for Scenario 1.  Therefore, as with  Scenario 1, construction air quality impacts would be less than significant with the  incorporation of Mitigation Measures AQ‐1 through AQ‐3.    At full development, Scenario 3 would result in 2,000 daily net new trips (as opposed to 3,126  for Scenario 1).  Therefore, as the majority of operational emissions are attributed to mobile  sources, Scenario 3 would result in fewer emissions than Scenario 1 (which do not exceed the  BAAQMD thresholds).  As with Scenario 1, operational impacts under Scenario 3 would be less  than significant.      Scenario 4    The development of Scenario 4 would result in a similar development plan as envisioned within  Scenario 3.  The primary difference would be that Scenario 4 proposes 600 senior units instead  of 516 high‐density units.  Construction related air quality impacts would be similar to that  presented for Scenario 3.  Therefore, as with Scenario 1, construction air quality impacts would  be less than significant with the incorporation of Mitigation Measures AQ‐1 through AQ‐3.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 40 March 2011  At full development, Scenario 4 would result in 1,442 daily net new trips (as opposed to 3,126  for Scenario 1).  Therefore, as the majority of operational emissions are attributed to mobile  sources, Scenario 4 would result in fewer emissions than Scenario 1 (which do not exceed the  BAAQMD thresholds).  As with Scenario 1, operational impacts under Scenario 4 would be less  than significant.     Mitigation Measures:

AQ‐3 RESULT IN A CUMULATIVELY CONSIDERABLE NET INCREASE OF  ANY CRITERIA POLLUTANT FOR WHICH THE AIR BASIN IS  NONATTAINMENT UNDER AN APPLICABLE FEDERAL OR STATE  AMBIENT AIR QUALITY STANDARD (INCLUDING RELEASING  EMISSIONS, WHICH EXCEED QUANTITATIVE THRESHOLDS FOR  OZONE PRECURSORS)?    Level of Significance Before Mitigation:  Potentially Significant.         Scenario 1    CUMULATIVE SHORT‐TERM EMISSIONS    As discussed above, the project’s construction‐related emissions would not exceed any of the  BAAQMD thresholds of significance with implementation of Mitigation Measures AQ‐1  through AQ‐3.  The BAAQMD CEQA Air Quality Guidelines do not include significance  thresholds for cumulative construction emissions.  However, due to the temporary nature of  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 42 March 2011  construction emissions, if the project’s emissions would be less than significant based on the  project‐level thresholds of significance, it can be expected that the project would not be a  cumulatively considerable contributor to a significant cumulative impact.  In addition, the  project would be required to implement the proposed BAAQMD Basic Construction Mitigation  Measures (Mitigation Measure AQ‐1), which are recommended for all projects whether or not  construction‐related emissions exceed the thresholds of significance.  The project would also  implement an Additional Control Mitigation Measure (AQ‐2) to reduce VOC/ROG emissions  from architectural coatings.  NOX emissions are reduced by Mitigation Measure AQ‐3.   Therefore, construction emissions associated with the proposed project would not result in a  cumulatively considerable contribution to cumulative air quality impacts.     CUMULATIVE LONG‐TERM EMISSIONS    The BAAQMD CEQA Air Quality Guidelines do not include separate significance thresholds for  cumulative operational emissions.  The BAAQMD CEQA Air Quality Guidelines note that the  nature of air emissions is largely a cumulative impact.  As a result, no single project is sufficient  in size to, by itself, result in nonattainment of ambient air quality standards.  Instead, a project’s  individual emissions contribute to existing cumulatively significant adverse air quality impacts.   The BAAQMD developed the operational thresholds of significance based on the level above  which a project’s individual emissions would result in a cumulatively considerable contribution  to the Basin’s existing air quality conditions.  Therefore, a project that exceeds the BAAQMD  operational thresholds would also be a cumulatively considerable contributor to a significant  cumulative impact.  As depicted in Table 7, above, the proposed project’s operational emissions  would not exceed BAAQMD thresholds for ROG, NOX, and PM.  Therefore, the impact of the  proposed project, in conjunction with related cumulative projects would not be cumulatively  considerable.  Impacts in this regard would be less than significant.    Scenario 1    With regards to cumulative health risks and hazards (further discuss below under Impact  Statement AQ‐4), the project would be located within 1,000 feet of SR‐85.  However, no other  sources of air toxics are located within the 1,000‐foot screening distance of the project site.     Further, Scenario 1 proposes all commercial uses, which the BAAQMD does not consider to be  sensitive receptors.  Additionally, Scenario 1 does not propose any uses that would be  considered a significant source of air toxics.  Therefore, the project would not be cumulatively  considerable and a less than significant impact would occur.        Scenario 2    As discussed above, Scenario 2 would result in fewer construction‐related emissions than  Scenario 1.  Implementation of Mitigation Measures AQ‐1 through AQ‐3 would ensure Scenario  2 would not exceed any of the BAAQMD thresholds of significance for construction.   Additionally, operational emissions under Scenario 2 would be less than those of Scenario 1  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 43 March 2011  (which do not exceed BAAQMD thresholds).  Therefore, Scenario 2 would not result in a  cumulatively considerable contribution to a significant cumulative impact.    With regards to cumulative health risks and hazards, although the project would be located  within 1,000 feet of SR‐85, Scenario 2 proposes all commercial uses, which the BAAQMD does  not consider to be sensitive receptors.  Scenario 2 does not propose any uses that would be  considered a significant source of air toxics.  Therefore, the project would not be cumulatively  considerable and a less than significant impact would occur.        Scenario 3    As discussed above, Scenario 3 would result in fewer construction‐related emissions than  Scenario 1.  Implementation of Mitigation Measures AQ‐1 through AQ‐3 would ensure Scenario  3 would not exceed any of the BAAQMD thresholds of significance for construction.   Additionally, operational emissions under Scenario 3 would be less than those of Scenario 1  (which do not exceed BAAQMD thresholds).  Therefore, Scenario 3 would not result in a  cumulatively considerable contribution to a significant cumulative impact.    With regards to cumulative health risks and hazards (further discuss below under Impact  Statement AQ‐4), the project would be located within 1,000 feet of SR‐85.  Scenario 3 proposes  commercial uses as well as high‐density residential units, which the BAAQMD considers to be  sensitive receptors.  Detailed modeling (which included cumulative traffic conditions) indicated  that residents on‐site within 261 feet of SR‐85 would be subject to health risk.  With  incorporation of Mitigation Measure AQ‐5, on‐site residents would not be subject to air toxics  from SR‐85 (refer to Impact Statement AQ‐4).  No other sources of air toxics are located within  the 1,000‐foot screening distance of the project site.  Additionally, Scenario 3 does not propose  any uses that would be considered a significant source of air toxics.  Therefore, the project  would not be cumulatively considerable and a less than significant impact would occur.        Scenario 4    As discussed above, Scenario 4 would result in fewer construction‐related emissions than  Scenario 1.  Implementation of Mitigation Measures AQ‐1 through AQ‐3 would ensure Scenario  4 would not exceed any of the BAAQMD thresholds of significance for construction.   Additionally, operational emissions under Scenario 4 would be less than those of Scenario 1  (which do not exceed BAAQMD thresholds).  Therefore, Scenario 4 would not result in a  cumulatively considerable contribution to a significant cumulative impact.    With regards to cumulative health risks and hazards (further discuss below under Impact  Statement AQ‐4), the project would be located within 1,000 feet of SR‐85.  Similar to Scenario 3,  Scenario 4 proposes commercial uses as well as senior living units, which the BAAQMD  considers to be sensitive receptors.  Detailed modeling (which included cumulative traffic  conditions) indicated that residents on‐site within 261 feet of SR‐85 would be subject to health  risk.  With incorporation of Mitigation Measure AQ‐5, on‐site residents would not be subject to  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 44 March 2011  air toxics from SR‐85 (refer to Impact Statement AQ‐4).  No other sources of air toxics are  located within the 1,000‐foot screening distance of the project site.  Additionally, Scenario 4 does  not propose any uses that would be considered a significant source of air toxics.  Therefore, the  project would not be cumulatively considerable and a less than significant impact would occur.        Mitigation Measures:  Refer to Mitigation Measures AQ‐1 through AQ‐3 and AQ‐5.     Level of Significance After Mitigation:  Less Than Significant.      AQ‐4 EXPOSE SENSITIVE RECEPTORS TO SUBSTANTIAL POLLUTANT  CONCENTRATIONS?    Level of Significance Before Mitigation:  Potentially Significant.        Sensitive receptors are defined as facilities or land uses that include members of the population  that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and  people with illnesses.  Examples of these sensitive receptors are residences, schools, hospitals,  and daycare centers.  CARB has identified the following groups of individuals as the most  likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and  persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and  bronchitis.  Sensitive receptors within the immediate vicinity of the project site are the existing  residences to the east, south, and west; also refer to Table 2.  Localized impacts from project  construction and operations are analyzed below.    Scenario 1    Localized Carbon Monoxide Hotspots    The Basin is designated as attainment for carbon monoxide (CO).  As indicated in the  BAAQMD CEQA Air Quality Guidelines, emissions and ambient concentrations of CO have  decreased dramatically in the Basin with the introduction of the catalytic converter in 1975.  No  exceedances of the CAAQS or NAAQS for CO have been recorded at nearby monitoring  stations since 1991.14   As a result, the screening criteria in the BAAQMD CEQA Air Quality  Guidelines note that that CO impacts may be determined to be less than significant if a project is  consistent with the applicable congestion management plan (CMP) and would not increase  traffic volumes at local intersections to more than 24,000 vehicles per hour for locations in  heavily urban areas, where “urban canyons” formed by buildings tend to reduce air circulation.      The project’s Traffic Impact Analysis has determined that the unsignalized intersections of  Winchester Boulevard/Albright Way and University Avenue/Lark Avenue would be impacted  with project implementation.  These intersections are expected to operate at unacceptable LOS E  and F during peak hours under background conditions.  The addition of project traffic would  14   Bay Area Air Quality Management District, BAAQMD CEQA Air Quality Guidelines (page 6‐1), June 2010.  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 45 March 2011  cause the intersections to degrade to LOS E and F during both peak hours with project  implementation.  The intersections also would meet signal warrants with the addition of project  traffic, which constitutes a significant impact by the Town standards.  Therefore, the Traffic  Impact Analysis includes mitigation requiring the signalization of the Winchester  Boulevard/Albright Way and University Avenue/Lark Avenue intersections to improve both  intersections to LOS B.  Additionally, the project would not violate the CMP criteria at any of  the CMP intersections, as noted in the Traffic Impact Analysis.  Therefore, the project would be  consistent with the CMP.  With implementation of the Traffic Impact Analysis mitigation, the  project would not significantly increase the delay or LOS at the study intersections, and would  not increase traffic volumes at local intersections to more than 24,000 vehicles per hour.   Therefore, effects related to CO concentrations would be less than significant.    Construction Toxic Air Contaminants    Construction‐related activities could result in the generation of toxic air contaminants (TACs),  specifically diesel particulate matter (DPM), from on‐road haul trucks and off‐road equipment  exhaust emissions.  Due to the variable nature of the proposed construction activity, the  generation of TAC emissions would be temporary, especially considering the short amount of  time such equipment is typically within an influential distance that would result in the  exposure of sensitive receptors to substantial concentrations.      The project construction period would occur over three phases and would require various types  of heavy equipment throughout each construction phase.  Specifically, demolition activities  would require tractors, dozers, and concrete/industrial saws.  Grading activities would require  tractors, graders, rubber tired dozers, and water trucks.  Trenching activities would require  excavators.  Paving activities would include cement and mortar mixers, pavers, rollers, and  other pieces of paving equipment.  The building phase would require one crane, two forklifts,  one tractor, three welders, and one generator set.  As indicated in the URBEMIS 2007 model  outputs (refer to Appendix A) for the proposed project, construction activities would generate a  maximum of 2.41 pounds of diesel PM2.5 exhaust per day.  Additionally, the project would  implement the BAAQMD’s Basic Construction Mitigation Measures (Mitigation Measure AQ‐ 1), which would also reduce DPM exhaust emissions.     As noted above, the closest sensitive receptors are the residential uses adjacent to the project site  to the south and east.  However, construction equipment during project construction would  move about the project site and would not be concentrated in one area or near one sensitive  receptor for an excessive duration of time capable of causing health effects.  Additionally, health  risks are associated with longer‐term exposure periods of nine, 40, and 70 years, which do not  correlate well with the temporary and highly variable nature of construction activities.15    Construction staging areas are generally planned to be concentrated toward the center of the  project site.  However, to ensure that sensitive uses in the vicinity of the project site are not  exposed to substantial TACs, Mitigation Measure AQ‐4 would require the implementation of  additional construction mitigation measures for off‐road equipment to reduce the exposure of  15   Bay Area Air Quality Management District, CEQA Air Quality Guidelines, June 2010.  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 46 March 2011  sensitive uses to TACs from construction emissions. The specific types of emission reduction  features identified in Mitigation Measure AQ‐4 would be determined based on the acreage  disturbed in a particular construction phase as well as the proximity of the construction activity  to sensitive uses.  With implementation of Mitigation Measures AQ‐1 and AQ‐4, impacts would  be reduced to less than significant levels.     Risk and Health Hazards    It is noted that the BAAQMD has revised the effective date for the risk and hazards thresholds  for new receptors from January 1, 2011 to May 1, 2011.  However, the BAAQMD CEQA Air  Quality Guidelines recommend that all toxic air contaminant (TAC) and particulate matter less  than 2.5 microns (PM2.5) sources located within a 1,000 foot radius of the proposed project site  be identified to determine any risk and health hazards.  There are no stationary TAC and PM2.5  sources located within 1,000 feet of the project site.16   However, SR‐85 is located to the north of  the project site with annual average daily traffic (AADT) of approximately 106,00017 , which  requires a risk and hazard screening analysis; refer to Exhibit 4, Phased Approach for Estimating  Community Risks and Hazards.      The BAAQMD CEQA Air Quality Guidelines defines a receptor to be “a place where people live,  play, or convalesce”.  These types of receptors would include residences, schools, school yards,  parks, daycare centers, nursing homes, and medical facilities.  Scenario 1 consists of all office  development, which the BAAQMD does not consider a sensitive receptor.  Therefore, risk and  health hazards from SR‐85 would be less than significant.      Scenario 2     The Winchester Boulevard/Albright Way and University Avenue/Lark Avenue intersections are  expected to operate at an unacceptable LOS during both peak hours under background  conditions and with implementation of Scenario 1.  Scenario 2 would result in fewer daily trips  than Scenario 1; however, it is anticipated that the intersection would still decrease to LOS F  and also meet signal warrants with the addition of project traffic, which constitutes a significant  impact by the Town standards.  Therefore, the mitigation requiring the signalization of the  intersection with protected left‐turn phasing on Winchester Boulevard (which would improve  the intersection LOS to LOS B) would also be required under Scenario 2.  Therefore, effects  related to CO concentrations would be less than significant under Scenario 2.     16

Guidelines, June 2010 Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 48 March 2011  Similar to Scenario 1, construction equipment during Scenario 2 construction would move  about the project site and would not be concentrated in one area or near one sensitive receptor  long enough to cause health effects.  Additionally, the project would implement the BAAQMD’s  Basic Construction Mitigation Measures (Mitigation Measure AQ‐1), which would also reduce  DPM exhaust emissions.  To ensure that sensitive uses in the vicinity of the project site are not  exposed to substantial TACs, Mitigation Measure AQ‐4 requires the implementation of  additional construction mitigation measures for off‐road equipment to reduce the exposure of  sensitive uses to TACs from construction emissions.  The specific types of reduction features

uses.  Similar to Scenario 1, implementation of Mitigation Measures AQ‐1 and AQ‐4 would  reduce impacts to less than significant levels.    As with Scenario 1, Scenario 2 consists of all office development, which the BAAQMD does not  consider a sensitive receptor.  Therefore, risk and health hazards from SR‐85 would be less than  significant.      Scenario 3    The intersections of Winchester Boulevard/Albright Way and University Avenue/Lark Avenue  are expected to operate at an unacceptable LOS during both peak hours under background  conditions and with implementation of Scenario 1.  Scenario 3 would result in fewer daily trips

impact by the Town standards.  Therefore, the mitigation within the Traffic Impact Analysis  requiring the signalization of the intersection with protected left‐turn phasing on Winchester  Boulevard (which would improve the intersection LOS to LOS B) would also be required under  Scenario 3.  Therefore, effects related to CO concentrations would be less than significant under  Scenario 3.    Similar to Scenario 1, construction equipment during Scenario 3 construction would move  about the project site and would not be concentrated in one area or near one sensitive receptor  long enough to cause health effects.  The project would implement the BAAQMD’s Basic  Construction Mitigation Measures (Mitigation Measure AQ‐1), which would also reduce DPM

additional construction mitigation measures for off‐road equipment to reduce the exposure of  sensitive uses to TACs from construction emissions.  The specific reduction features identified

uses.  Similar to Scenario 1, implementation of Mitigation Measures AQ‐1 and AQ‐4 would  reduce impacts to less than significant levels.    Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 49 March 2011  Scenario 3 consists of office development as well as residential uses, which could be located  within the 1,000‐foot screening distance of SR‐85.  Following the BAAQMD risk and hazard  screening analysis process, Scenario 3 would exceed the initial and advanced screening criteria  for PM2.5 and lifetime excess cancer risk, requiring further analysis and modeling.  Utilizing the  BAAQMD screening tables and criteria (from the BAAQMD’s Recommended Methods for  Screening and Modeling Local Risks and Hazards), a 300‐foot buffer for PM2.5 and a 265‐foot buffer  for lifetime excess cancer risk would be required between the centerline of SR‐85 and proposed  residential uses.  Because the Scenario 3 would exceed the screening criteria, consistent with the  BAAQMD CEQA Guidelines, a refined dispersion modeling analysis was conducted utilizing  local meteorology, emission rates, and highway estimates.  Refined dispersion modeling was  performed using the Breeze Roads GIS Pro interface for the EPA’s CAL3QHCR model, which is  a roadway model that predicts air pollutant concentrations from motor vehicles.  The dispersion  modeling utilized traffic data from Caltrans, as well as emissions rates and vehicle fleet data  from the EMFAC2007 model.18   Based on the results of the screening analysis described above,  receptors were modeled at 100‐foot increments from the SR‐85 centerline.  Table 8, Risk and  Health Hazards from State Route 85, depicts the results of the modeling.  As indicated in Table 8, a  300‐foot buffer would ensure that BAAQMD significance thresholds would not be exceeded.   However, it should be noted that Table 8 also indicates that at 261 feet from the SR‐85  centerline, the projected cancer risk would be just below the BAAQMD threshold; refer to

BAAQMD reductions are presented in percentage ranges for specific sectors (i.e., transportation, natural gas). Each sector’s reduction percentages are scaled proportionally to their sector of the project-generated emissions. For example, transportation emissions account for 53.56 percent of the total emissions, and a 39.40 percent reduction would apply to transportation related emissions. Therefore, the reduction is calculated by multiplying 0.5356 by 0.3940 for a scaled reduction of 0.2110 (21.10 percent). This was completed for each sector. The total emissions reduction applied to the project is a sum of the scaled sector reduction percentages (44.34 percent).     BAAQMD Sector Reduction Methodology    The BAAQMD provides GHG reduction measures and associated reduction percentages in  their CEQA Air Quality Guidelines.  Reductions are presented in percentage ranges for each  measure, and apply specifically to mobile, electricity, and natural gas sectors.  Reductions from  BAAQMD measures are scaled proportionally to their sector of project‐generated emissions.   For example, if measures would result in a 39.40 percent reduction in transportation‐related  emissions, and transportation accounts for 53.56 percent of the total emissions, then the scaled  reduction would be 21.10 percent (0.5356 x 0.3940 = 0.2110).  This process is completed for each  sector.  The total emission reductions are summed and applied to the overall total project‐ related GHG emissions.  As presented in Table 10 and Table 11, Scenario 1 Greenhouse Gas  Emissions With BAAQMD Sector Reductions, the overall reduction percentages total 44.34  percent.  Applying the BAAQMD reduction percentages, GHG emissions from the proposed  project would be reduced by 3,104.36 MTCO2eq/yr, which equates to 4.56 MT CO2eq/SP/yr.  A  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 57 March 2011  service population of 857 employees is used (based on one employee per 350 square feet of  office space).  Thus, the project would not exceed the 4.6 MT CO2eq/SP/yr threshold utilizing the  BAAQMD scaled reduction methodology.     Table 11  Scenario 1 Greenhouse Gas Emissions With BAAQMD Sector Reductions    Sector Reductions Breakdown % of Total GHG Business as Usual Emissions % of Sector Reductions Scaled Reductions Calculation4 Scaled Reduction % Transportation 53.56 39.40 0.5356 x 0.3940 = 0.2110 21.10 Natural Gas 6.00 25.00 0.0600 x 0.2500 = 0.0150 1.50 Electricity 36.84 59.00 0.3684 x 0.5900 = 0.2174 21.74 Total Scaled % Reduction 44.34 Total Project-Related Business as Usual Emissions1,3 7,001.26 MT CO2eq/yr Total Project-Related GHG Emissions WITH 48.26% Reduction1,3 3,897.02 MT CO2eq/yr = 4.56 MT CO2eq/SP2 /yr BAAQMD GHG Threshold 4.6 MT CO2eq/SP/yr Mitigated GHG Emissions Exceed Threshold? No Notes: 1. Total project-related GHG emissions = total direct emissions + total indirect emissions (in MT CO2eq/yr). 2. SP = service population. The SP for the project is assumed to be 857 employees, based on one employee per 350 square feet of office space. The total project-related GHG emissions were divided by the SP of 857 for the annual GHG emissions per SP. 3. Totals may be off due to rounding. 4. BAAQMD reductions are presented in percentage ranges for specific sectors (i.e., transportation, natural gas). Each sector’s reduction percentages are scaled proportionally to their sector of the project-generated emissions. For example, transportation emissions account for 53.56 percent of the total emissions, and a 39.40 percent reduction would apply to transportation related emissions. Therefore, the reduction is calculated by multiplying 0.5356 by 0.3940 for a scaled reduction of 0.2110 (21.10 percent). This was completed for each sector. The total emissions reduction applied to the project is a sum of the scaled sector reduction percentages (44.34 percent).     Conclusion    As shown in Table 9, operational‐related emissions under Scenario 1 would be 7,001.26  MTCO2eq/yr (8.17 MTCO2eq/SP/yr) without reductions from project design features, which  exceeds the BAAQMD GHG significance threshold of 4.6 MT CO2eq/SP/yr.  URBEMIS 2007 and  the BAAQMD CEQA Air Quality Guidelines were used to quantify GHG emissions reductions  associated with project design features from project operations.  With implementation of project  design features (which are required by Mitigation Measure GHG‐1), the project would  incorporate sustainable practices which include water, energy, solid waste, and transportation  efficiency measures that are summarized in Table 10.  Based on the reduction measures in Table  10, Scenario 1 would reduce its GHG emissions 44.34 percent below the business as usual  scenario, and would reduce the project’s operational GHG emissions to 3,897.02 MT CO2eq/yr.   The project would have a service population of 857 employees and the total GHG emissions  after reductions would equate to 4.56 MT CO2eq/SP/yr.  Therefore, the project would not exceed  the 4.6 MT CO2eq/SP/yr threshold utilizing the BAAQMD scaled reduction methodology.   Impacts in this regard would be less than significant.    Albright Way Development Project

under Scenario 1.  Construction impacts would be less than those associated with Scenario 1, as  less development is proposed.  At full development, Scenario 2 would result in 948 daily net  new trips (69.67 percent reduction from 3,126 for Scenario 1).  Proportionately reducing GHG  emissions by 69.67 percent (proportion that Scenario 2 square footage is reduced by compared  to Scenario 1) results in a total BAU emissions total of approximately 2,123.71 MT CO2eq/yr.   Utilizing a SP of 260 (350 s.f. per employee), Scenario 2 would result in 8.17 MT CO2eq/SP/yr,  which would exceed the BAAQMD GHG threshold.      Therefore, Scenario 2 would be required to incorporate BAAQMD GHG mitigation measures to  be below the 4.6 MT CO2eq/SP/yr threshold.  Scenario 2 would be required to incorporate  Mitigation Measure GHG‐1.  With implementation of Mitigation Measure GHG‐1, Scenario 2  would reduce its GHG emissions by a scaled 44.34 percent, which equates to 1,182.05 MT  CO2eq/yr and 4.55 MT CO2eq/SP/yr, which falls below the BAAQMD GHG threshold.  With  implementation of Mitigation Measure GHG‐1, impacts would be reduced to less than  significant levels.     Scenario 3    The development of Scenario 3 would consist of 200,000 s.f. of commercial office space as well  as up to 516 high‐density units.  Utilizing the URBEMIS 2007 and BGM models, the total GHG  emissions associated with Scenario 3 would be 6,870.34 MT CO2eq/yr.  Utilizing a SP of 1,223  (based on 350 s.f. per employee [with a net decrease of 50,000 s.f. of office space] and 2.39  persons per household), Scenario 3 would result in 5.61 MT CO2eq/SP/yr, which is above the 4.6  MT CO2eq/SP/yr GHG threshold.  Therefore, Scenario 3 would be required to incorporate  BAAQMD GHG mitigation measures to be below the 4.6 MT CO2eq/SP/yr threshold.  Scenario 3  would be required to incorporate Mitigation Measure GHG‐1.  With implementation of  Mitigation Measure GHG‐1, Scenario 3 would reduce its GHG emissions by a scaled 18.5  percent, which equates to 5,599.33 MT CO2eq/yr and 4.58 MT CO2eq/SP/yr, which falls below  the BAAQMD GHG threshold.  With implementation of Mitigation Measure GHG‐1, impacts  would be reduced to less than significant levels.     Scenario 4    The development of Scenario 4 consists of 200,000 s.f. of commercial office space as well as up to  600 senior living units.  Utilizing the URBEMIS 2007 and BGM models, the total GHG emissions  associated with Scenario 4 would be 8,994.56 MT CO2eq/yr.  Utilizing a SP of 1,057 (based on  350 s.f. per employee [with a net decrease of 50,000 s.f. of office space] and 2.0 persons per  household), Scenario 4 would result in 8.46 MT CO2eq/SP/yr, which is above the 4.6 MT  CO2eq/SP/yr GHG threshold.  Therefore, Scenario 4 would be required to incorporate  BAAQMD GHG mitigation measures to be below the 4.6 MT CO2eq/SP/yr threshold.  Scenario 4  would be required to incorporate Mitigation Measure GHG‐1.  With implementation of  Mitigation Measure GHG‐1, Scenario 4 would reduce its GHG emissions by a scaled 46 percent,  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 59 March 2011  which equates to 4,857.06 MT CO2eq/yr and 4.59 MT CO2eq/SP/yr, which falls below the  BAAQMD GHG threshold.  With implementation of Mitigation Measure GHG‐1, impacts  would be reduced to less than significant levels.    Mitigation Measures:      GHG‐1 A combination of the following is a list of sustainability and design features that  shall be incorporated into Scenarios 1, 2, 3, or 4 to achieve the overall scaled  reduction in GHG emissions to ensure a less than significant GHG impact (Scenarios  1 and 2 require a 44.34 percent scaled reduction, Scenario 3 requires an 18.5 percent  scaled reduction, and Scenario 4 requires a 46 percent scaled reduction in GHG  emissions).  Prior to the issuance of building permits, the applicant shall demonstrate  the incorporation of a combination (one or more) of sustainable project design  features that would reduce the project’s GHG emissions by the percentage required  above.  Each measure and the associated GHG reduction shall be identified and  included on all project plans and specifications.  One or more of the following  sustainability and design features, or other measures that may be available in the  future, shall be included to achieve the reduction in GHG emissions:    • Provide secure on‐site bike parking (ratio shall be at least one space per 20  vehicle spaces).  • Provide information on transportation alternatives (i.e., bus schedules and  maps) accessible to employees within each proposed building.  • Provide preferential on‐site carpool/vanpool parking.  • Increase energy efficiency beyond Title 24 by 20 percent.  • Install smart meters and programmable thermostats.  • Plant shade trees within 40 feet of the south side or within 60 feet of the west  sides of the buildings.  • Install roofs with highly reflective materials (albedo of at least 30) to reduce  cooling load.  • Meet 2010 Green Building Code Standards.  • Seal heating, ventilation, and air conditioning (HVAC) ducts to enhance  efficiency and reduce energy loss.  • Include solar photovoltaic or other technology to generate electricity on‐site  to reduce consumption from the electrical grid.    • Implement an employee telecommuting program.  • Provide showers/changing facilities on‐site for employee use.  • Implement an on‐site carpool matching program for employees.  • Provide on‐site amenities (i.e., eating and other establishments).  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 60 March 2011  • Increase the project design by 100 percent (i.e., presence of transit oriented  development design guidelines, complete streets standards).  • Work with the Bay Area Air Quality Management District (BAAQMD) to  implement acceptable off‐site mitigation.  This involves an agreement with  the BAAQMD and payment of fees or the purchase of carbon credits.  The  BAAQMD would commit to reducing the type and amount of emissions  identified in the agreement.    Also refer to Mitigation Measures AQ‐1 and AQ‐3.    Level of Significance After Mitigation:  Less Than Significant.      GHG‐2  CONFLICT WITH AN APPLICABLE PLAN, POLICY OR REGULATION  ADOPTED FOR THE PURPOSE OF REDUCING THE EMISSIONS OF  GREENHOUSE GASES?    Level of Significance Before Mitigation:  Less Than Significant.      Scenario 1    According to the BAAQMD, a GHG reduction plan should:    • Quantify GHG emissions, both existing and projected over a specified time period,  resulting from activities within a defined geographic area;  • Establish a level, based on substantial evidence, below which the contribution to GHG  emissions from activities covered by the plan would not be cumulatively considerable;  • Identify and analyze the GHG emissions resulting from specific actions or categories of  actions anticipated within the geographic area;  • Specify measures or a group of measures, including performance standards, that  substantial evidence demonstrates, if implemented on a project‐by‐project basis, would  collectively achieve the specified emissions level;  • Establish a mechanism to monitor the plan’s progress toward achieving the level and to  require amendment if the plan is not achieving specified levels; and  • Be adopted in a public process following environmental review.    The GHG reduction plan should identify goals, policies, and implementation measures that  would achieve the goals of AB 32 for the entire community.  The Town of Los Gatos does not  currently have an applicable plan, policy, or regulation adopted for the purpose of reducing the  emissions of GHGs.  Therefore, the proposed project would not conflict with an adopted plan,  policy, or regulation pertaining to GHGs.  Also, as described above, the proposed project would  comply with the 2010 California Green Building Code and would include design features to  reduce energy and water consumption and reduce vehicle trips.  The project would not hinder  Albright Way Development Project      Air Quality & Greenhouse Gas Assessment 61 March 2011  the Stateʹs GHG reduction goals established by AB 32.  Thus, a less than significant impact  would occur in this regard.    Scenario 2    Refer to the discussion under Scenario 1.     Scenario 3    Refer to the discussion under Scenario 1.     Scenario 4

I also spent several hours at the site on February 16, looking at the trees and referring to the previous documents. My assignment for this project is as follows: 1. Review the previous Arborist Report and Tree Location Exhibit (page 2) 2. Develop specific tree protection measures for those trees proposed to be retained (page 2) 3. Identify key specimen trees to retain on the site (if possible), and prepare tree protection measures for these trees. (page 6) 4. Develop tree protection measures for any other tree that it may be possible to retain (page 10) ****************************** I certify that the information contained in this report is correct to the best of my knowledge, and that this report was prepared in good faith.

Review of previous Arborist Report and Tree Location Exhibit: There are 440 existing trees described in the previous arborist report. The majority these (391 trees) are tentatively proposed for removal, as part of a “worst case scenario” for CEQA purposes. There are three groups of trees along the perimeter of the property that the developer proposes to save at this time, totaling 49 trees. The condition of the great majority of the trees on this site is listed as “Fair” or less, as per the July 10 Arborist Report. Only one tree on the site is listed as having “Good” condition, and this is tree #283, a 7-inch trunk diameter Chinese pistache tree. The next-best category of trees in terms of tree condition is “Fair to Good”. There are 118 trees in this category, which is 27% of the entire tree population. Although these “Fair to Good” trees are scattered throughout the site, the majority of them are located in the west-central portion of the site including most of the trees that are proposed to be saved along Winchester Boulevard. I have highlighted and labeled this area on the Tree Location Exhibit Plan on the next page. I did not recheck every tree and the tree data listed in the previous Arborist Report. Based upon spending several hours at the site and referencing the information in the report on a dozen or so trees, I can say that I agree with the tree condition ratings. The tree trunk diameters and tree sizes listed also seem to be correct. In my opinion the Arborist Report by McClenahan is a good report and it will be a useful tool in helping to make final decisions on which specific trees to save or remove. 2. Develop specific tree protection measures for those trees proposed to be retained a) The Town of Los Gatos General Tree Protection Directions are included on page 11. These minimum standards will apply to all trees that will be retained on the site, and involve primarily tree protection fencing. In these directions either 5 or 6-foot high chain link fencing is allowed. In order to provide maximum protection for trees to be retained I require that only 6-foot high chain link fencing be used. b) In addition I have provided some Supplemental Tree Protection Specifications that address construction zone/tree protection topics other than tree protection fencing; for example dealing with tree roots, tree irrigation, pruning for construction clearance, etc. These Supplemental Specifications begin on page 12. c) There are 3 main groups of trees that are proposed to be saved; all located along the perimeter of the project. I have labeled these trees as Groups A, B and C in the Tree Exhibit Location Plan on the next page. I have also attached a separate, larger copy of this plan for your convenience. To follow is a short description of each group, and the main tree protection considerations for that group.

Ellis, 2/17/11) A separate, larger copy of this plan is also enclosed 1) Group A on the southern property line adjacent to the existing residential area near Charter Oaks Drive includes 17 trees (#124 – 132, 134 - 141): This row of trees includes mostly coast redwoods with several deodar cedars and one red gum (#141). All trees are listed as having “Fair” or less condition. Trunk diameters of the trees range from 8 to 25 inches, with most in the 12 to 18 inch range. These trees serve as screen trees between adjacent properties. There is a deep drainage swale between the trees and the adjacent property to the south. This swale will make installing tree protection fencing on both sides of the trees difficult. Since there will not be any construction on the neighboring property (and there may have to be a perimeter construction fence along the property line anyway) the tree protection fencing may be placed on the project (North) side and at each end of the tree row (East and West) sides. Spacing will be tight between the tree protection fence and the existing buildings and PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 4 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 other improvements, but it can be done. Fencing should be placed as far from the tree trunks as possible while still allowing demolition to proceed. After demolition is completed, the tree protection fencing may need to be moved farther from the tree trunks; the setback for proposed parking will be 15 feet from the property line. Before this location is finalized I want to check and make sure this will be far enough from the trees. It is possible that some trees may be recommended for removal if grading will be too close to the trunk. The final tree protection fencing should be placed as far from the tree trunks as possible while still allowing construction to take place. The project consulting arborist must assist in the fencing location process in order to make sure that the fencing is not located unnecessarily close to the tree trunks. This will depend somewhat on whether or not the existing swale will be filled in between the trees and the proposed parking lot. Group A trees to save, the east end of the tree row with red gum #141.

There are also a few coast live oaks and one Aristocrat pear. Trunk diameters range from 7 to 23 inches. All of the trees are listed as having “Fair” or less condition. These trees are located within or on the perimeter of an existing parking area, adjacent to a residential area to the south. Recommendations for tree protection fencing are the same as for Group A trees. I will also need to check the actual distances from tree trunks to improvements to make sure all of the trees can actually be saved. Group B trees to save.

There are 22 trees in this tree row; mostly redwoods and deodar cedars. The applicant states that the majority of the site improvements will be in areas of the site that are already developed with parking and other improvements, so it will be possible to save these trees. Most of these trees are listed as having “Fair to Good” condition, a lesser number in “Fair” condition and a few trees in “Fair to Poor” condition. Recommendations for tree protection fencing are also the same as for Group A trees, and I will also need to check the distances to improvements to make sure all of the trees can actually be saved. 3. Identify key specimen trees to retain on the site (if possible), and prepare tree protection measures for these trees. There are a lot of nice trees on this site, and although many of these trees are not perfect, they are worth saving if possible. The best trees on site seem to be the large Canary Island pines, coast redwoods and deodar cedars. There are also many nice smaller trees such as crape myrtles and flowering pears. There are many similar trees to these and other species in various areas of the site, Group C trees to save starting with Coast redwood #346 at the North end and progressing South to #324. PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 7 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 and it is difficult to differentiate between them in order to pick out “key” trees. So instead I recommend trying to save as many trees in “Fair to Good” to “Good” condition as possible, with a lesser number of trees in “Fair” condition. Trees listed in “Fair to Poor” condition should probably be removed. Trees in “Poor” condition should definitely be removed. It is important to understand that by “save” I mean designing improvements and landscaping around these trees so that the trees can survive for a long time, for example 20 years or more. Do not try to fit the trees into too-small spaces where they will quickly decline, die or fail. How much room does an individual tree need? We never really know, but we (by we, I mean arborists including myself) have some guidelines that we start with, for planning purposes. More on this in Section #4 of this report. Some of the larger and most impressive trees on site (the numbers and locations of these trees are included in the Tree Exhibit map in this report): • Red oak #93: I think this is probably a pin oak (Quercus palustris) or another eastern U.S. oak species. The tree’s trunk diameter is 16. 8 inches, overall tree size 50 feet tall by 20 feet wide, “Fair to Good” condition, canopy overlaps with canopies of other trees. This is a very large specimen for this oak in this area. Its relatively large size and fair to good condition on this site; probably due to the large uncovered (no buildings or pavement) ground surface around the tree. I strongly encourage you to design around this tree in order to save it. Right now it is scheduled to be removed. Root protection distances: This tree should have a minimum of 7 feet undisturbed of soil all around the trunk, including any over- excavation margins required beyond improvements. This means 7’ + 7’ + 2’ trunk width = 16 foot diameter circle, with the trunk in the center. Use this as a preliminary planning guideline only – I will work with the architects to come up with a final plan for this tree. Distances to buildings or other improvements that might interfere with the canopy of this tree must also be taken into consideration. Don’t locate a building close to the tree so that a large amount of the tree’s canopy will have to be removed – this will ruin the aesthetic appeal of this fine oak. On the Tree Exhibit Plan this oak may be located far away enough from a proposed parking lot and other improvements, if this plan is implemented. This oak species is from to the eastern United States and does require summer irrigation in this area, as receives now. PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 8 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 • Valley oak #268: This is the largest tree on the site in terms of trunk diameter, at 44.6 inches. It is 55 feet in height with a canopy spread of 60 feet. Condition is listed as “Fair”, and I would agree with this rating. This is an impressive tree, and it is a native, natural-growth oak that pre-existed site development. So far this old oak has survived less-than-ideal environmental changes around it – such as an irrigated landscape area filled with English ivy. The reason for the tree’s survival is probably due at least in part to the relatively large uncovered ground-surface area in which is it located. I would not make a final decision to keep this tree until it is evaluated in greater detail; especially to see if there are any obvious root problems close to the trunk (because the tree has been located in an irrigated area). For such an investigation a root collar excavation1 would be necessary. I also advise a thorough aerial inspection2 of the tree. If after these tests the tree is a candidate for saving, the landscape area in which it is located should not be made any smaller width-wise, and it should be at least as long as the dripline of the tree length-wise. Preferably the uncovered ground area around the tree should be made larger. This tree really deserves a “mini-park” around it in order to do it justice. McClenahan listed this tree as in only “Fair” condition for a good reason – it is in “so-so” condition and if there is something significantly wrong with it now or if it will be mistreated through development and relandscaping in the future, then it should not be saved. Another important consideration is whether or not this tree will be located in a frequently used high- target area. Right now it is located alongside a proposed parking lot area and is shown to be removed. If the tree remains, it should preferably be located in a large, unplanted, non-irrigated and mulched area with none to infrequent irrigation. The tree should receive infrequent summer irrigation for the first few years after relandscaping in order to wean it off the irrigation it is receiving now. 1 Root collar excavation and examination: The root collar (junction between trunk and roots) is critical to whole-tree health and stability. A root collar excavation carefully uncovers this area (with hand digging tools, water or pressurized air). The area is then examined to assess its health and structural stability. 2 Aerial inspection: an experienced tree climber climbs into the tree and looks for and examines in greater detail, any structural defects and concerns from within the tree canopy. Such defects may not be visible or may not be visible enough from the ground in order to make a more accurate assessment of their significance. If reporting back to another consulting arborist, the climber may notes, take photographs or perform certain tests (such as advanced decay detection tests with certain decay detection instrumentation). PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 9 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 • Deodar cedars #118, 119 and 120: These trees have trunk diameters of 26.6, 22.6 and 28.5 inches respectively, heights of 50, 48 and 45 feet and canopy spreads of 40, 35 and 45 feet. Functionally these trees are a grove3 which should be preserved intact. They are a very nice large group of trees of a different species than most of the larger trees on site, which are redwoods, Canary Island pines and ash trees. The condition rating for all three deodar cedars is “Fair” with tree #119 and 120 listed as being somewhat chlorotic4 . Chlorosis can be caused by many things, but with these trees it may something very minor. It may be worthwhile to further evaluate these trees and their present environment in more detail, to determine whether it would be worthwhile to try to save them. I would start first with a root collar excavation. If that checks out alright then I would investigate soil pH5 in the planting area. If the trees will remain, the landscape area in which they are located should not be reduced in size. The size of the present landscape area probably has much to do with the size and relatively good condition of the trees. 3 Grove: is a group of trees that located close together that shelter each other from wind and the elements, having “knit” canopies. If of the same species, there is usually root grafting between trees, which lends support from the ground, as well as water and mineral sharing. Removal of one or some grove members could cause remaining members to be unstable due to a reduction of previous shelter. Grove trees often have asymmetrical canopies when viewed as individuals. 4 Chlorotic: a plant symptom of discolored (yellowish) plant tissue that should (usually) be green in color. The loss of green color is due to the destruction of the green pigment chlorophyll, which can be due to many causes including certain plant diseases. A high soil pH is a common cause of chlorosis in this area. 5 pH: a measure of acidity or alkalinity ranging from 1 to 14, on a logarithmic scale. A measurement of 1 is most acidic, 14 is most alkaline, and 7 is neutral. Soil pH influences the availability of plant nutrients. Most plants prefer soils with pH between 6 and 7. Many acid soil adapted plants prefer soil pH in the 4 – 5 range, and plants adapted to alkaline conditions prefer soil pH above 7, often 8 to 10. Few plants grow at the extreme ends of the pH scale (3 or less, or greater than 10).

Develop tree protection measures for any other tree that it may be possible to retain I have provided some specific tree protection measures for the Group A, B and C trees, as well as for the specimen trees mentioned previously in Section 3. If other trees are retained I may develop more specific measures for them as well, including minimum root and canopy protection zones. In general however, the Town of Los Gatos Tree Protection Directions (page 11) must be followed, as well as the more detailed Supplemental Tree Protection Specifications I have included beginning on page 12. For planning purposes I recommend keeping in mind the following information regarding tree protection distances, which I use: 3 to 5 X DBH No one can estimate and predict with absolute certainty how far a soil disturbance such as an excavation must be from the edge of the trunk of an individual tree to affect tree stability or health at a low, moderate or severe degree -- there are simply too many variable involved that we cannot see or anticipate. 3xDBH however, is a reasonable “rule of thumb” minimum distance (in feet) any excavation should be from the edge of the trunk on one side of the trunk. This is supported by several separate research studies including (Smiley, Fraedrich, & Hendrickson 2002, Bartlett Tree Research Laboratories. DBH is trunk “diameter at breast height” (4.5 feet above the ground). This distance is often used during the design and planning phases of a construction project in order to estimate root damage to a tree due to the proposed construction. It tends to correlate reasonably well with the zone of rapid taper, which is the area in which the large buttress roots (main support roots close to the trunk) rapidly decrease in diameter with increasing distance from the trunk. For example, using the 3X DBH guideline an excavation should be no closer than 4.5 feet from the trunk of an 18-inch DBH tree. Such distances are guidelines only, and should be increased for trees with heavy canopies, significant leans, decay, structural problems, etc. It is also important to understand that in actual field conditions we often find that much less root damage occurs than was anticipated by the guidelines. 3xDBH may be more of an aid in preserving tree stability and not necessarily long-term tree health. 5X DBH or greater is the “preferred” minimum distance which should be strived for, and this distance or greater should probably be used when there are multiple trenches on more than one side of the trunk. The roots beyond the zone of rapid taper form an extensive network of long, rope-like roots one to two inches in diameter. These woody perennial roots are referred to as transport roots because they function primarily to transport water and minerals. Maintaining a 5xDBH tree protection zone or greater around a tree will preserve more of these transport roots, which will have less of an impact on tree health than if the excavation were closer to the trunk. OTPZ (Optimum Tree Protection Zone) OTPZ is the distance in feet from the trunk of the tree, all around the tree, that construction or other disturbance should not encroach within. If this zone is respected, then chances of the tree surviving construction disturbance are very good. This method takes into account tree age and the particular species tolerance to root disturbance. Although there are no scientifically based methods to determine the minimum distance for construction (for example, root severance) from trees to assure their survival and stability, there are some guidelines that are often used in the arboricultural industry. The most current guideline comes from the text, Trees & Development, Matheny et al., International Society of Arboriculture, 1998. The tree protection zone calculation method in this text was used to obtain the OTPZ’s provided in this report. Due to the crowded, constrained nature of many building sites it is often not be possible to maintain the OPTZ distance recommended for many of the trees -- therefore I have also listed alternate distances of 3 and 5X DBH (see paragraph above).

For paving area that will not be demolished and when stipulated in a tree preservation plan, posts may be supported by a concrete base. 2) Area type to be fenced. Type I: Enclosure with chain link fencing of either the entire dripline area or at the tree protection zone (TPZ), when specified by a certified or consulting arborist. Type II: Enclosure for street trees located in a planter strip: chain link fence around the entire planter strip to the outer branches. Type III: Protection for a tree located in a small planter cutout only (such as downtown): orange plastic fencing shall be wrapped around the trunk from the ground to the first branch with 2-inch wooden boards bound securely on the outside. Caution shall be used to avoid damaging any bark or branches. 3) Duration of Type I, II, III fencing. Fencing shall be erected before demolition, grading or construction begins and remain in place until final landscaping is required. Contractor shall first obtain the approval of the project arborist on record prior to removing a tree protection fence. 4) Warning sign. Each tree fence shall have prominently displayed an 8.5 x 11-inch sign stating: "Warning—Tree Protection Zone-this fence shall not be removed and is subject to penalty according to Town Code 29.10.1025". b) All persons, shall comply with the following precautions: 1) Prior to the commencement of construction, install the fence at the dripline, or tree protection zone (TPZ) when specified in an approved arborist report, around any tree and/or vegetation to be retained which could be affected by the construction and prohibit any storage of construction materials or other materials or vehicles inside the fence. The dripline shall not be altered in any way so as to increase the encroachment of the construction. 2) Prohibit excavation, grading, drainage and leveling within the dripline of the tree unless approved by the director. 3) Prohibit disposal or depositing of oil, gasoline, chemicals or other harmful materials within the dripline of or in drainage channels, swales or areas that may lead to the dripline of a protected tree 4) Prohibit the attachment of wires, signs or ropes to any protected tree. 5) Design utility services and irrigation lines to be located outside of the dripline when feasible. 6) Retain the services of the certified or consulting arborist for periodic monitoring of the project site and the health of those trees to be preserved. The certified or consulting arborist shall be present whenever activities occur that pose a potential threat to the health of the trees to be preserved. 7) The director and project arborist shall be notified of any damage that occurs to a protected tree during construction so that proper treatment may be administered.

Consulting Arborist & Horticulturist, 2/17/11) 1) GENERAL: a Read and understand these entire Specifications prior to the beginning of any work on site. Call the project arborist if you have any questions or concerns before any site work begins. b These Tree Protection Specifications Apply To Any Existing Tree On Site That Will Not Be Removed And Will Be Within Or Near Any Area Where Demo Or Construction Will Occur. This includes any tree that is not located in an area that is completely fenced off from construction with a perimeter construction fence. If any portion of the canopy of a tree outside the construction zone overhangs a perimeter construction fence, these specifications shall apply to such trees as well. c The consulting arborist for this project may be Deborah Ellis or another consulting arborist pre-approved by Deborah Ellis. The project arborist will be in charge of tree protection site inspections and other arborist services on an as needed basis for the duration of the project. The project arborist must be either an International Society of Arboriculture (ISA) Board-Certified Master Arborist or an American Society of Consulting Arborists (ASCA) Registered Consulting Arborist. d The general contractor or owner should arrange to hire laborers who’s specific job it will be to carry out the tree protection work; for example installing (and moving if necessary) tree protection fencing, obtaining and spreading mulch, watering trees, etc. Qualified tree services (recommended by the project arborist) can do some of this work such as watering trees (e.g. water jet irrigation), and other specialized tasks such as pruning. This recommendation is designed to avoid the problem of not having the labor to do tree protection tasks as written in these Specifications and also any additional work requested by the project arborist. a The contractor shall include a separate line item in their Schedule of Values for Tree Protection e Unexpected conditions occur and changes are necessary on all construction projects. Such situations may necessitate that changes or modifications be made to these Tree Protection Specifications. Any concerns or conflicts with these Specifications should be brought to the attention of the project arborist immediately so that alternate methods may be agreed upon. f Notify the arborist as soon as there are changes in site and construction management, for example a new site superintendent, a different construction management company and/or contact, a different City planner working on the project, etc. The arborist must always be provided with current contact information for the parties who are involved with the project.

Use the least-damaging improvements possible when working near trees, for example pier on grade beam foundation (with no excavation for grade beam) instead of slab with concrete perimeter foundation, or a cantilevered foundation, or pathways constructed on existing grade with little or no excavation and comprised of porous material such as gold fines. Alterations of natural grade must ensure that water drains away rather than toward tree trunks. b Landscaping should be compatible with existing trees. Refrain from rototilling within tree driplines. Any planting within this area should be done by hand and not using power equipment such as soil augers. Plants and new irrigation including irrigation trenching are best kept at least 5 to 10 feet away from the trunks of existing trees (or 3xDBH6 , whichever is greater), depending upon the size and type of tree, and the environmental conditions. Farther is better. Some established tree species should have no planting or irrigation in their vicinity, for example California native oaks. Refrain from making any major changes to the present landscape environment, as large mature trees often cannot adapt so such changes and may decline and die over time because of them. Contact the project arborist for assistance in the landscape design phase if necessary. c Underground utilities: Deborah Ellis has not reviewed the utility plans. Every attempt should be made to keep underground utility lines outside tree protection zones. If any utility lines will pass through tree protection zones, Deborah Ellis or the project arborist must review these plans and prescribe any mitigation procedures that will reduce damage to trees such as tunneling below or between roots to remain, air spade7 excavation of trenches, hand digging or a combination of such methods. It utilities must pass through tree protection zones, the project arborist must be on site to supervise this work and assist in dealing with roots. Abandoned pipes and utilities should be cut at existing grade and not pulled out, if their removal would damage tree roots. d Bioswales are very “green” but they can also be very damaging to tree roots, which is not green. Please do not locate bioswales near trees and especially not within tree protection zones. e Construction Vehicle Access: There should be a defined route for construction vehicles and large equipment, in order to reduce damage to trees and other vegetation. Clearly show and label 6 DBH is tree trunk diameter in inches “at breast height”, measured at 4.5 feet above ground level. This is the forestry and arboricultural standard measurement height that is also used in many tree-related calculations. 7 Air spade: a commercial grade, hand-held metal probe attached to a large air compressor by a hose. This equipment is specialized, industrial equipment that is intended for use by trained professionals. Pressurized air is discharged from the tip of the probe. The air is used to excavate soil away from items such as tree roots, or to dig trenches or remove soil with minimal damage to tree roots (compared to traditional soil removal methods). Information for horticultural uses of the air spade is available at on line at: http://www.air-spade.com/market_arboriculture.html. Pre-irrigation to soften the soil a few days before is recommended, and is often done by the company that is providing the service. In addition it is also helpful to use a pickaxe to loosen very hard surface soil before and often during the use of an air spade. Air spade works is somewhat expensive, but it may be economical if a root collar or other excavation is extensive, difficult, the tree species is very sensitive to root damage, if many roots must be exposed, the undersides of roots must be exposed, or multiple excavations will occur. You may contact me for referrals to companies that provide this service.

Preferably there should be one entrance and one exit to the site. f Designated Storage & Parking Areas: There must be designated storage and parking areas on site, away from protected trees. Such areas must be shown on the Tree Protection Plan as well as grading and other applicable construction plans. g The existing trees that will be retained on the project site must be shown and numbered (with the tree numbers used in the arborist report for this project) on all applicable construction plans such as the general site plan, demo plan, grading/drainage/utility plan, landscape and irrigation plans. Tree Protection Fencing locations for the trees must be shown on the Demolition and Grading plans. h These specifications must be included in their entirety on a separate, dedicated plan sheet in the general plans. The plan sheet shall be entitled EXISTING TREE PROTECTION. 3) PRE-DEMOLITION/CONSTRUCTION: a Pre-Demolition/Construction Meeting at the site shall be conducted with the project arborist, the developer, and the general contractor. The general contractor is responsible to see that these tree protection specifications are implemented and that all people working at the site are aware and adhere to these specifications. A copy of these Specifications is to remain and be accessible at the site at all times. Additional meetings on site with workers may be necessary and should be organized with the project arborist. Tail-gate meetings may be recommended to include review of unusual circumstances, conditions or procedures to be followed. b Irrigation. Make sure that any trees that will be near construction or demo disturbance are well hydrated before any demo or construction work begins. Irrigate the trees if necessary approximately 2 weeks before any work will begin if the soil is not moist to at least 12 inches below the surface8 . This will help the trees go into the project strong and not drought-stressed, so they will be better able to weather any damage they may experience. The frequency and amount of water will depend upon the weather, the damage to the tree, and the soil moisture status. The project arborist should provide directions for irrigation depending upon tree condition just prior to construction, site conditions, weather and other factors. Be prepared to supply the trees with non- recycled water from a water truck at least several times per week during the normally rainless months, as well as if there is insufficient rain during the normal wet season. c Pruning for Site Access and Construction Clearance. Tree pruning should be as little as possible, and only what is required to allow site access, demo and construction. An exception to this would be pruning to mitigate an acute hazardous condition, which should always be done as soon as possible. Aesthetic or other pruning can be done after the project has been completed so do not mix this with site access or construction pruning. Prior any work begins on site perform site access clearance pruning only. Do not do any construction clearance pruning until improvements have been staked in the field, in order to avoid unnecessary pruning. Branches 8 At the Project Arborist’s discretion, such irrigation may include drought tolerant trees which should normally be “summer dry” such as native California oaks, if they are expected to experience root damage during construction.

Use a qualified tree service with an ISA Certified Arborist on staff, in a supervisory position for the work, and pre-approved by the project arborist. The tree pruner shall follow the most current version of the arboriculture industry standards: i) Tree Pruning Standards: • Best Management Practices, Tree Pruning. 2008. International Society of Arboriculture, PO Box 3129, Champaign, IL 61826-3129. 217-355-9411. • ANSI Z1331 American National Standards for Tree Care Operations. 2006 Edition. Secretariat: National Arborist Association, Inc. American National Standards Institute, 11 West 42nd St., New York, New York, 10036. (Covers safety). • ANSI A300 Pruning Standards. 2008 Edition. Ibid. (Covers tree care methodology). o If urgent pruning is necessary for immediate construction clearance this may be done by the general or demo contractor. In this case a short stub should be left which can be removed by a qualified tree service at a later time. Please consult with the project arborist prior to such pruning. d Fencing (see also Town of Los Gatos General Tree Protection Directions, page 11. i) The arborist must meet with the general contractor prior to any work beginning on site, to discuss tree protection fencing requirements and to agree upon tree protection fencing. The arborist must also inspect tree protection fencing after it has been installed and before any work begins, and sign-off on the fencing before any work may begin on site, including demolition. After inspection of the fencing the arborist must supply a letter stating that the fencing is either adequate or inadequate. If the fencing is adequate, work may begin on site. If the fencing is inadequate then directions to make the fencing adequate will be included in the letter. Any changes to original tree protection fencing maps or directions must be included in the letter from the arborist. ii) Install Tree Protection Fencing BEFORE any demolition or construction begins. The area inside the fencing is termed the TPZ (Tree Protection Zone). In all cases place the fencing as far from protected tree’s trunks as possible, in order to provide the maximum amount of protected space for each tree or group of trees as well as future landscape areas in general, while still allowing for site work to progress. The fencing shall not be taken down or moved without the project arborist’s permission. The arborist should be on site during demo near the trees and should also supervise any necessary work inside the fencing. iii) Tree Protection Fencing and all Tree Protection Practices must also remain in place and in effect during landscape installation to the greatest extent possible. A great deal of damage can occur to trees during the landscaping phase of a project. Do not remove fencing to begin landscape work until the project arborist approves fence removal or moving. It is likely that some of the tree protection will need to remain in place during landscaping. The arborist should be on site to supervise landscape work within the vicinity of protected existing trees. The landscape contractor should meet on site with the project arborist to review the Tree Protection Specifications and discuss how existing tree protection will continue to be carried out during landscaping. iv) Four-foot high orange plastic fencing may be used for tree protection fencing in certain areas where the terrain makes the use of the required cyclone fencing PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 16 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 difficult, or in certain other situations as approved by the project arborist. The project arborist must pre-approve any plastic fencing locations. If plastic fencing is used, it must be installed as follows: (1) Metal T-posts shall be used as the fencing posts. These posts shall be driven at least 12 inches into the ground and shall extend up to the top of the 4-foot orange plastic fencing. Stakes must be placed no further than 6 feet apart (closer if necessary to keep the fencing taught). The plastic fencing must be attached to the metal posts with plastic wire ties – one tie around fencing and post at the top, bottom and middle of the length of the post above the ground. A top wire must be strung through the fencing and must loop around near the top of the post to additionally stabilize the fencing. v) Tree Protection Fencing locations for the trees must be shown on the Demolition and Grading plans. vi) Durable neon-colored flagging tape can be woven through the top of the fence, or about 12 inches of orange plastic ski fencing can be attached to the top of the cyclone fencing to increase visibility to vehicle operators. vii) If it is not possible to fence off a particular tree, then the trunk of the tree must be wrapped spirally with a commercial straw wattle roll from the ground up to at least the height of the lowest branches or 10 feet, whichever is less. The wattling is then wrapped with orange plastic fencing so that it covers the entire wattling. Meet with the project arborist to determine how each tree will be specifically dealt with in this manner. Such trees also require ground protection underneath as much of the dripline as possible as specified in item # 4.b. viii) Alternate fencing for small areas: ¾ or 1” thick plywood, 4 or 5 feet tall can be supported with an above-ground from constructed from 2x4” lumber, as tree protection for a small area such as a cut-out planter in a paved area. ix) Fencing Phases & Locations: x) Pre-Demo: Install this phase of tree protection fencing before any demolition begins. The fencing shall be installed 1 to 2 feet beyond existing structures or pavement to be removed (or slightly more if necessary to allow for work) required for each improvement. In all cases place the fencing as far from protected tree’s trunks as possible, in order to provide the maximum amount of protected space. For this particular project, the easiest thing to do would be to fence off as much of the project from the trees, where this is possible, instead of fencing off individual trees from construction. Of course, do fence off individual trees or groups of trees, when necessary to protect them. xi) Post-Demo, Pre-Construction: Move the fencing outward to 1 to 2 feet beyond proposed structures or other improvement (or more if necessary to allow for work) required for each improvement, otherwise at or beyond the dripline of the tree (or groups of trees), whichever is greater. In all cases place the fencing as far from protected tree’s trunks as possible, in order to provide the maximum amount of protected space the trees as well as any additional future landscaping. As with pre-demo fencing, the fencing should enclose as much of the site outside of the construction zone as possible, not just a small area around the trunk, or the driplines of individual trees. You will need additional fencing for this phase, since the fencing will have to enclose a larger area than for demo.

If any portion of the canopy of a tree on adjacent property or on jobsite property overhangs the construction zone and/or perimeter construction zone fencing, these specifications shall apply to such trees as well. The portion of the canopy that overhangs the job site must be fenced off at the dripline or as close to this distance as possible while allowing for construction work. xiii) Tree Protection Signage shall be posted on the fencing every 25 feet or in each cardinal direction (whichever is less), clearly proclaiming that there is to be no unauthorized work or persons within the tree protection zone, no dumping of chemicals or storage of materials or equipment, and who to contact regarding this. Use the template sign that I have provided. Signs must be either laminated or metal. For more durable and reusable signs, you may send the template and explanatory sheet (also available from me) to a sign company to have the appropriate number of durable aluminum signs made for the project. Signs must be attached to the fencing with plastic wire ties – 1 wire tie at each of the 4 corners. e Mulching. No supplemental mulching is required for existing trees to remain on this project – however; the existing natural topsoil, surface plant litter and live vegetation must remain in place until landscaping, in order to protect the root system of the trees. No site clearing or grubbing (e.g. scraping of surface of soil to remove vegetation and plant debris) shall occur except in the distinct areas where improvements will be located. Depending upon tree and site conditions, the project arborist may call for mulch material (tree trimming chippings from a local tree service) to be delivered to the site and spread around trees as the project progresses. 4) DURING DEMO/CONSTRUCTION a) Except in the distinct areas where improvements will be located and soil disturbance is necessary for construction, the existing natural topsoil, surface plant litter and live vegetation must remain in place until landscaping, in order to protect the root system of the trees. No site clearing or grubbing (e.g. scraping of surface of soil to remove vegetation and plant debris) shall occur except in those areas approved for soil disturbance. Depending upon tree and site conditions, the project arborist may call for mulch material (tree trimming chippings from a local tree service) to be delivered to the site and spread around trees as the project progresses. b) Unavoidable Vehicle Traffic within Tree Protection Zones: Where vehicles or equipment must travel within tree protection zones, protection of the soil to reduce compaction must be accomplished through one of the following: i) Apply 6-12 inches of woodchip mulch to the area ii) Lay ¾ inch thick plywood or 4 x 4 inch wood beams over a 4+ inch thick layer of mulch iii) Apply 4 to 6 inches of gravel over a taut, staked geotextile fabric iv) Placing commercial logging or road mats on top of a 4+ inch thick mulch layer v) Note that stone, geotextile and mulch exceeding 4 inches in depth will need to be removed after work in the area has been completed. c) Unavoidable foot traffic or worker access for construction within tree protection zones: The ground surface should be cushioned with flakes taken from bales of hay and overlain with ¾ or 1” thick sheets of plywood. Use at least 2 layers of flakes (or as many as needed to provide PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 18 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 a 4 to 6 inch height. Move this protection as needed to build the addition, but keep as much of this protection in place as possible. Usually I specify 6-inches of mulch overlain by plywood, but the hay bale flakes will provide a more uniform height and stable surface for the construction workers. d) Do Not Dump Cement Tailings, Chemicals or Other Waste Products into any Future Landscape Area, not just within tree protection zones. Preferably, have a designated washout pit far from landscape areas. e) Liming of the soil for soil compaction is not allowed near trees. Liming is toxic to plant roots! If there will be any liming on site consult with the project arborist long beforehand in order to make sure that the lime is not anywhere near trees or other vegetation that is planned to be saved. A very large lime-free buffer zone should be maintained between vegetation and liming. f) Dealing with Roots that are exposed, must be removed or are damaged: i) Covering Roots: Exposed roots 2-inches in diameter or larger within the Tree Protection Zone shall be covered (either by backfilling or with other permanent covering) as soon as possible. If possible spray uncovered exposed roots within one hour of uncovering with non- recycled water to thoroughly moisten the roots and the surrounding soil. Trench walls must be covered with draping at least 2 layers of non-synthetic burlap or bed sheets or carpet sections (carpet surface facing roots) or cardboard over the upper 3 feet of trench walls. The covering materials must be kept wet until backfilled to reduce evaporation from trench walls. Horizontal cuts or root exposure on the soil surface: Spray with water within 1 hour of uncovering. If possible spread mulch over the exposed surface and wet the mulch thoroughly with water after spreading. Alternatively two or more layers of non-synthetic burlap, carpet sections, cardboard or other material approved by the Project Arborist may be used for soil covering. ii) Cutting Roots: Damaged roots 2-inches in diameter or larger shall be cut back to undamaged root tissue whenever possible and practical. Damaged roots less than 2 inches in diameter in the Tree Protection Zone may (and are encouraged) to be cut back to undamaged tissue. Damaged roots 4 inches or greater in diameter may not be cut without the Project Arborist’s approval – try to tunnel underneath or otherwise preserve these roots if possible. Exposed roots that are not damaged but must be removed follow the same procedures as above. Root cutting should be done with sharp tools, at a right angle and as close to the soil line as possible. Cut back to a lateral root when possible when this will not increase the extent of root loss or damage. It is strongly recommended that the Project Arborist (with their own root cutting equipment) be on site during these times to assist with root assessment and cutting and to document and make recommendations regarding root damage. (1) Place all cut root sections in a pile near where the roots have been cut, so the Project Arborist can review and document. (2) Sometimes less root damage will occur if roots are precut 6 to 12 inches beyond the planned excavation. Specialized root-pruning equipment such as a Vermeer™ or Dosco™ root pruner machine can be used. If roots are not precut, then encountered roots that must be removed must be cut cleanly and at a right angle if possible. If you are uncertain about the size or status of roots and what to do about them, contact the Project Arborist for assistance. (3) Methods of root pruning (in descending order of preference): PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 19 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 (a) Soil excavation using (1) air spade or pressurized water (hydro-excavation)9 (b) Hand digging with hand tools. Followed by selective root cutting, and leaving roots intact (digging underneath) when possible. (c) Using a root cutting machine (e.g. Dosco™ or Vermeer™ Root Pruner) cutting along predetermined line on the soil surface. These machines cut roots cleanly, but indiscriminately. (d) Mechanically excavating (e.g. with trencher or backhoe) and hand pruning what is left of roots. Preferably use backhoe, work slowly and have ground person cleanly cut roots as soon as possible after encountered. (4) The following root cutting tools are mandatory for the contractor: (a) Round-blade shovel (b) Large mattock (c) Tree pruning saws designed for root cutting (d) Pruning loppers with 1-inch diameter capacity (5) The following root cutting tools are recommended for the contractor : (a) Hand mattock (b) Hand trowel shovel (c) Recipro-saw with wood cutting blades (especially pruning blades – have several new blades on hand) (d) Concrete circular saw (rock or root cutting saw, e.g. Stihl TS-400 with a 12-inch blade, preferably carbon or diamond-tipped – start with a new blade and have extra blades on hand). (e) Chain saws (for large roots, e.g. over 4 inches in diameter start with a new chain and have extra chains on hand) iii) Management of construction activities that impact roots: (1) If heavy equipment is used for grading, a ground person (preferably the project Arborist) listens and watches for roots as does the equipment operator. When roots are encountered that must be removed, grading stops and the roots are cut right away rather than tearing them back toward the trunk by continuing to operate the heavy equipment. If hand digging is used for grading the same procedure is followed. Use appropriate tools for the root(s) in question. In order to properly cut roots you may have to carefully dig back into the soil by hand with a shovel, hand trowel or mattock behind the root, so have these tools on hand as well. Digging back behind or underneath roots may be necessary in order to have room to operate the saw and cut the root. Grade cuts must be kept moist by spraying frequently with water until they are covered or backfilled. (2) Trench excavations: must be dug by hand, air spade or by mechanically tunneling under roots within the area underneath the canopy of trees or the 3xDBH distance for that tree, whichever is greater. Any exceptions to this requirement require written permission from the Project Arborist. (3) When mechanical tunneling (boring) is substituted for open trenching, maintain the following depths per trunk DBH in Table 1 below. The nearest edge of the excavation for launching and recovery pits must be located a minimum of 3xDBH distance from the edge 9 Hydro-excavation requires that the soil/water slurry be vacuumed up and placed somewhere. A temporary holding area can be constructed with double-stacked railroad ties lined with polyethylene plastic. The slurry can be left to dry and then picked up more easily. PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 20 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 of the trunk of the tree. Less root damage will occur if the tunnel is located directly underneath the trunk versus to the side of the trunk. Table 1 4) When using a backhoe to remove soil near trees: The backhoe or other equipment must sit on existing pavement (if available) and work backwards so as to remain on the pavement or otherwise outside tree protection zones, or at least as far away from tree trunks as is possible. Work very slowly with the backhoe, removing soil in no greater than 6 inch lifts, and have 2 workers on the ground with shovels and a large and small mattock (preferably one of the workers is the Project Arborist) watching for roots. The backhoe operator should “feel” for roots as well. As roots are uncovered and/or contacted the ground workers cut roots cleanly with a saw as directed in item #4.c. above 5) For basement or underground garage excavations use soil nailing and shotcrete construction to avoid over-excavation. 6) Structure demolition: structures should be collapsed inward and/or away from adjacent trees. Demolition equipment must sit outside tree protection zones. 7) Pavement removal: This may be done with a backhoe if done carefully so as not to damage the trunk of the tree, and to disturb the roots of the tree as little as possible. The backhoe or other equipment must sit on existing pavement and work backwards so as to remain on the pavement or otherwise outside tree protection zones. Alternatively, pavement may be broken into manageable pieces (e.g. by hand with jackhammer) and hand placed onto a loader. Where roots larger than 2 inches in diameter have grown into the existing base course material, use the existing material as the new material and do not remove and replace it. 8) Trees to be removed: Trees to be removed must be removed without damaging trees that will remain. If tree canopies are knit together (branches from more than one tree intermingle with each other) then the demo contractor may NOT remove these trees – they must instead be removed by a qualified tree service that will cut the trees down carefully in order to avoid PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 21 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 damage to adjacent trees. If trees to be removed are far away from trees that will remain, the demo contractor may remove these trees by pulling or pushing them over as long as roots or aboveground portions of nearby remaining trees will not be damaged. Alternatively grind the stumps of trees to be removed to 12 inches below grade, again if this grinding will not be near trees that will remain. If trees to be removed are close to trees that will remain then do not push or pull over the tree or grind the stump, but rather cut the trunk to a stump that is as flush with the ground as possible. The method of tree removal should be agreed upon at the site on a tree by tree basis between the Project Arborist and contractor prior to any tree removals. 9) Damage to trees : Any damage or injury to trees shall be reported within 6-hours to the Project Arborist, if applicable. All mechanical or chemical injury to branches, trunk or to roots over 2- inches in diameter shall be reported in the monthly Tree Protection Inspection Report. In the event of injury, the Project Arborist shall prescribe mitigation measures such as: • Root injury: Bark or trunk wounding: Current bark tracing and treatment methods shall be performed by a qualified tree care specialist within two days. • Scaffold branch or leaf canopy injury: Remove broken or torn branches back to an appropriate branch capable of resuming terminal growth within five days. If leaves are heat scorched from equipment exhaust pipes, consult the Project Arborist within 6 hours. • Penalty for damage to street trees: In the event that street trees or their roots have been damaged, the contractor shall be subject to the penalty rate of $100.00 per inch of damage Measurement of the damage shall be the width of the wound measured across the grain at the widest point. Penalty fee shall be paid to the Town and deposited to the general fund as required. 5) OTHER: a No herbicides are allowed to be used underneath pavement or in any other area on site. b Dust Control Program. During periods of extended drought, wind or grading, spray wash trunk, limbs and foliage to remove accumulated construction dust. The Project Arborist may request that this be done at their discretion. c Trees shall not be fertilized before, during or after the construction process unless specifically prescribed by the Project Arborist. Most fertilizer applications to established trees in this area are unnecessary and often cause more harm than good. For example, nitrogen increases plant metabolism and can put additional stress on trees that are already under stress from site (environment) changes and root damage such as commonly occurs during construction projects. Fertilization can also promote unnecessary growth of foliage which removes energy reserves from roots and increases the tree water requirement. Fertilizers are salts that increase the osmotic potential of the soil and can magnify drought stress injury to plants. d Moving/Transplanting Trees: i) Use a qualified tree moving service pre-approved by the Project Arborist. The tree moving service should irrigate the trees thoroughly 1 to 2 weeks prior to digging, move and replant the trees, construct an 8-inch high water berm 12 inches beyond the edge of the newly planted tree rootballs, irrigate the transplanted trees thoroughly after moving by hand with a hose and hose- end watering wand, set up a temporary drip irrigation system for the newly planted trees, install a PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 22 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 4 inch depth of coarse wood chip mulch within the planting hole, and be hired by the contractor or to inspect and maintain the trees during the duration of construction and until landscaping is completed. ii) If possible, it will assist the tree’s establishment in its new location to pre-cut roots 6 to 12 inches inside the root ball that will be dug when the tree is planted. Precutting should preferably be done about 6 month prior to digging, but no later than 3 months prior to digging. iii) If trees will be stored prior to planting there must be a designated storage area for the trees on site, where non-recycled water is available. The trees must be fenced off (as a group if necessary or as individual trees) from construction as per the previous fencing directions with the addition that the fencing must be placed outside the dripline of the tree(s). During storage and preferably at planting orient the tree in the same direction as it was positioned in the landscape. To assist proper orientation draw a red `N’ (for North) with a construction crayon on the trunk of the tree. iv) If the trees will be planted immediately after digging, tree root collars must remain at the same elevation above grade as existed prior to digging. Immediately after replanting into the landscape construct an 8-inch high water berm 12 inches beyond the edge of the newly planted tree rootball, irrigate the transplanted tree thoroughly after moving by hand with a hose and hose- end watering wand, set up an adequate irrigation system for the newly planted tree and install a 4 inch depth of coarse wood chip mulch within the planting hole. v) Tree protection fencing must be placed beyond the planting hole and also beyond the canopy of the replanted tree. 6) TREE PROTECTION SUPERVISION a Tree Protection Inspections & Documentation: The Project Arborist must supervise any work within the tree protection zone, or when roots or branches of the tree are encountered or are expected to be encountered – whether or not these are within or above the TPZ. The Project Arborist will inspect the site for tree protection specification compliance at least monthly from prior to demolition until immediately after construction is completed. Immediately after each tree protection inspection an inspection report should be submitted to the Project Manager for distribution. The inspection report shall include status of the following: i) Inspector name and contact information ii) Date and time of inspection: iii) Date of last inspection iv) Reason for inspection v) Weather (approximate temperature, any rainfall, etc.) vi) Current demolition or construction work on site vii) Additional demolition or construction work completed since last inspection viii) Tree protection fencing status (including tree protection signage) ix) Mulching status (if required) x) Tree work done within last inspection period (pruning, irrigation, etc.) xi) Grading, trenching, excavations, cut or exposed roots, root recutting and protection xii) Other b The following Project Arborist site inspections are mandatory and must be documented as per the items listed in Tree Protection Inspections & Documentation, item 6.a. above: PO Box 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. 90-160 Albright Way & 14600 Winchester Blvd. Page 23 of 23 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 i) Tree Protection Fencing. The project contractor and City Planning Department planner assigned to the project shall be in receipt of a written statement from the Project Arborist verifying that he/she has conducted a field inspection of the trees and that the protective tree fencing is in place. ii) Pre-Construction Meeting. Prior to commencement of demolition or construction, the Project Arborist shall conduct a pre-demolition/construction meeting to discuss tree protection with the site superintendent, grading equipment operators and the owner’s representatives. iii) Inspections of Rough Grading or Trenching. The Project Arborist shall perform an inspection during the course of rough grading adjacent to the Tree Protection Zone to ensure trees will not be injured by compaction, but or fill, drainage and trenching, and if required, inspect tree wells, drains and special paving. The contractor shall provide the Project Arborist at least 48 hours advance notice of such activity. iv) Monthly General Tree Protection Inspections: The Project Arborist shall perform monthly inspections to monitor changing site and tree condition. These inspections should preferably be unannounced. The City Planning Department planner assigned to the project, the general contractor and the job superintendent shall be in receipt of the monthly inspection reports containing status of the topics listed in item 6.a. above. v) Special Activity within the Tree Protection Zone. Work within this area requires the direct onsite supervision of the Project Arborist. 7) Enclosures: a Tree Protection Sign Template (D.

Acoustical Assessment iii March 2011  DEFINITIONS OF COMMONLY USED TERMS IN NOISE CONTROL    The definitions that follow are in general agreement with those contained in publications of  various professional organizations, including the American National Standards Institute  (ANSI); the American Society for Testing and Materials (ASTM); the American Society of  Heating, Refrigerating and Air‐Conditioning Engineers (ASHRAE); the International  Organization for Standardization (ISO); and the International Electrotechnical Commission  (IEC).      TERMINOLOGY    acoustic; acoustical:  Acoustic is usually used when the term being qualified designates  something that has the properties, dimensions, or physical characteristics associated with sound  waves (e.g., acoustic power); acoustical is usually used when the term which it modifies does not  explicitly designate something that has the properties, dimensions, or physical characteristics of  sound (e.g., acoustical material).    ambient noise:  The all‐encompassing noise associated with a given environment at a specified  time, usually being a composite of sound from many sources arriving from many directions,  near and far; no particular sound is dominant.      attenuation:  The decrease in level of sound, usually from absorption, divergence, scattering, or  the cancellation of the sound waves.    average sound level (Leq):  The level of a steady sound which, in a stated time period and at a  stated location, has the same A‐weighted sound energy as the time‐varying sound.   Unit: decibel.    A‐weighted sound level (LA):  The sound level measured with a sound‐level meter using A‐  weighting.  Unit: decibel (dBA).      background noise:  The total noise from all sources other than a particular sound that is of  interest (e.g., other than the noise being measured or other than the speech or music being  listened to).    decibel (dB):  A unit of level which denotes the ratio between two quantities that are  proportional to power; the number of decibels correspond to the logarithm (to the base 10) of  this ratio.  [In many sound fields, the sound pressure ratios are not proportional to the  corresponding power ratios, but it is common practice to extend the use of the decibel to such  cases.  One decibel equals one‐tenth of a bel.]    equivalent continuous sound level (average sound level) (Leq):  The level of a steady sound

impacts resulting from implementation of the proposed Albright Way Development Project  (project).  The project is located in the Town of Los Gatos (Town), along Albright Way,  southeast of the State Route 85 (SR‐85) and Winchester Boulevard interchange.       The project proposes a Planned Development zoning that will all for flexibility in the ultimate  mix of land uses on the site.  The project may consist of office alone or a mix of office and high‐ density /senior residential units.  As currently proposed, the project could include up to a  maximum of 550,000 square feet of office space, or a combination of less office space with  residential uses.  Residential uses could include up to a maximum of 516 high‐density dwelling  units or 600 senior residential uses.  This Acoustical Assessment evaluates Scenario 1 as  identified in the March 17, 2011 Albright Way Development Traffic Impact Analysis.  Scenario 1  consists of the replacement of 250,000 square feet of existing office park buildings with new  office buildings totaling 550,000 square feet.  Under Scenario 1, the new office buildings would  provide an additional 300,000 square feet of office space and result in additional 3,126 daily  vehicle trips.  Three parking structures are also proposed under this Scenario.  As noted, the  Planned Development zoning will provide flexibility for mixed use scenarios, provided that the  noise impacts of those scenarios are not substantially more severe than the noise impacts of  Scenario 1.    Temporary Impacts.  Based upon the results of the analysis, construction activities would be  perceptible at nearby sensitive receptors.  However, the Town’s Municipal Code exempts  construction activities during permitted hours.  Implementation of the recommended mitigation  measures would further reduce short‐term noise impacts.  Temporary noise impacts would be  less than significant for each scenario.    Long‐Term Impacts.  The analysis has concluded that project implementation would result in less  than significant impacts in regard to mobile and stationary sources for each scenario.    Cumulative Impacts.  The proposed project would increase traffic noise levels on local roadways  when comparing the “Existing” to “Cumulative With Project” scenario.  However, the proposed  project would result in less than significant cumulative impacts to noise levels along local  roadway segments for each scenario.             Albright Way Development Project   Acoustical Assessment 2 March 2011  1.0 INTRODUCTION AND PROJECT SUMMARY    The purpose of this Acoustical Assessment is to evaluate potential short‐ and long‐term noise  impacts resulting from implementation of the Albright Way Development Project (project),  located in the Town of Los Gatos (Town).       1.1 PROJECT LOCATION    The project is located in the Town of Los Gatos, California; refer to Exhibit 1, Regional Vicinity.   Specifically, the project site is located along Albright Way, southeast of the State Route 85 (SR‐ 85) and Winchester Boulevard interchange; refer to Exhibit 2, Local Vicinity Map.      1.2 PROJECT CHARACTERISTICS    The project proposes a Planned Development zoning that will all for flexibility in the ultimate mix of  land uses on the site.  The project may consist of office alone or a mix of office and high‐density  /senior residential units.  As currently proposed, the project could include up to a maximum of  550,000 square feet of office space, or a combination of less office space with residential uses.   Residential uses could include up to a maximum of 516 high‐density dwelling units or 600 senior  residential uses.  An evaluation of each of the potential land use scenarios indicates that the  development of the project site as all office uses would result in the greatest amount of traffic being  added to the roadway system.1   Therefore, as vehicle trips are typically largest source of noise for  development projects of this type, this analysis evaluates the Scenario 1 as identified  in the March 17,  2011 Albright Way Development Traffic Impact Analysis.  Scenario 1 consists of the replacement of  250,000 square feet (s.f.) of existing office park buildings with new office buildings totaling 550,000  s.f.; refer to Exhibit 3, Conceptual Site Layout.      It should be noted that the project may ultimately consist of office alone or a mix of office and high‐ density/senior residential uses. The Town has developed additional illustrative land use scenarios:    • Scenario 1: Replacement of the 250,000 s.f. of existing office park buildings on the site with  new office buildings totaling 550,000 s.f.  • Scenario 2: Minimum of 200,000 s.f. new office plus 141,000 s.f. (remaining) office  • Scenario 3: 200,000 s.f. new office plus up to 516 high‐density units   • Scenario 4: 200,000 s.f. new office plus up to 600 senior units     Because the office use would generate more daily and peak hour trips than would residential, this  study first presents the analysis of a proposed project scenario consisting of the replacement of the  250,000 s.f. of existing office park buildings on the site with new office buildings totaling 550,000 s.f.   Then, in order to determine whether the addition of residential uses would generate any greater  impacts than the 550,000 s.f. office scenario, supplemental analyses were completed for the three  additional scenarios.   1   Hexagon Transportation Consultants, Inc., Albright Way Development Traffic Impact Analysis, March 17, 2011.  PACIFIC OCEAN STANISLAUS COUNTY SANTA CLARA COUNTY ALAMEDA

Albright Way Development Project   Acoustical Assessment 6 March 2011  2.0 DESCRIPTION OF NOISE METRICS    2.1 STANDARD UNIT OF MEASUREMENT    Sound is described in terms of the loudness (amplitude) of the sound and frequency (pitch) of  the sound.  The standard unit of measurement of the loudness of sound is the decibel (dB).   Since the human ear is not equally sensitive to sound at all frequencies, a special frequency‐ dependent rating scale has been devised to relate noise to human sensitivity.  The A‐weighted  decibel scale (dBA) performs this compensation by differentiating among frequencies in a  manner approximating the sensitivity of the human ear.    Decibels are based on the logarithmic scale.  The logarithmic scale compresses the wide range in  sound pressure levels to a more usable range of numbers in a manner similar to the Richter  scale used to measure earthquakes.  In terms of human response to noise, a sound 10 dBA  higher than another is perceived to be twice as loud and 20 dBA higher is perceived to be four  times as loud, and so forth.  Everyday sounds normally range from 30 dBA (very quiet) to 100  dBA (very loud).  Examples of various sound levels in different environments are illustrated on  Exhibit 4, Common Environmental Noise Levels.    Many methods have been developed for evaluating community noise to account for, among  other things:    • The variation of noise levels over time;  • The influence of periodic individual loud events; and  • The community response to changes in the community noise environment.    Table 1, Noise Descriptors, provides a listing of methods to measure sound over a period of time.    2.2 HEALTH EFFECTS OF NOISE    Human response to sound is highly individualized.  Annoyance is the most common issue  regarding community noise.  The percentage of people claiming to be annoyed by noise  generally increases with the environmental sound level.  However, many factors also influence  people’s response to noise.  The factors can include the character of the noise, the variability of  the sound level, the presence of tones or impulses, and the time of day of the occurrence.   Additionally, non‐acoustical factors, such as the person’s opinion of the noise source, the ability  to adapt to the noise, the attitude towards the source and those associated with it, and the  predictability of the noise, all influence people’s response.  As such, response to noise varies  widely from one person to another and with any particular noise, individual responses would  range from “not annoyed” to “highly annoyed.”  1/26/11 JN 40-100419-17193 MAS Exhibit 4 Common Environmental Noise Levels ALBRIGHT WAY DEVELOPMENT PROJECT ACOUSTICAL ASSESSMENT Albright Way Development Project   Acoustical Assessment 8 March 2011  Table 1  Noise Descriptors    Term Definition Decibel (dB) The unit for measuring the volume of sound equal to 10 times the logarithm (base 10) of the ratio of the pressure of a measured sound to a reference pressure (20 micropascals). A-Weighted Decibel (dBA) A sound measurement scale that adjusts the pressure of individual frequencies according to human sensitivities. The scale accounts for the fact that the region of highest sensitivity for the human ear is between 2,000 and 4,000 cycles per second (hertz). Equivalent Sound Level (Leq) The sound level containing the same total energy as a time varying signal over a given time period. The Leq is the value that expresses the time averaged total energy of a fluctuating sound level. Maximum Sound Level (Lmax) The highest individual sound level (dBA) occurring over a given time period. Minimum Sound Level (Lmin) The lowest individual sound level (dBA) occurring over a given time period. Community Noise Equivalent Level (CNEL) A rating of community noise exposure to all sources of sound that differentiates between daytime, evening, and nighttime noise exposure. These adjustments are +5 dBA for the evening, 7:00 PM to 10:00 PM, and +10 dBA for the night, 10:00 PM to 7:00 AM. Day/Night Average (Ldn) The Ldn is a measure of the 24-hour average noise level at a given location. It was adopted by the U.S. Environmental Protection Agency for developing criteria for the evaluation of community noise exposure. It is based on a measure of the average noise level over a given time period called the Leq. The Ldn is calculated by averaging the Leq’s for each hour of the day at a given location after penalizing the “sleeping hours” (defined as 10:00 PM to 7:00 AM) by 10 dBA to account for the increased sensitivity of people to noises that occur at night. Exceedance Level (Ln) The A-weighted noise levels that are exceeded 1%, 10%, 50%, and 90% (L01, L10, L50, L90, respectively) of the time during the measurement period. Source: Cyril M. Harris, Handbook of Noise Control, 1979.     When the noise level of an activity rises above 70 dBA, the chance of receiving a complaint is  possible, and as the noise level rises, dissatisfaction among the public steadily increases.  However, an individual’s reaction to a particular noise depends on many factors, such as the  source of the sound, its loudness relative to the background noise, and the time of day.  The  reaction to noise can also be highly subjective; the perceived effect of a particular noise can vary  widely among individuals in a community.      The effects of noise are often only transitory, but adverse effects can be cumulative with  prolonged or repeated exposure.  The effects of noise on the community can be organized into  six broad categories:    • Noise‐Induced Hearing Loss;  • Interference with Communication;  • Effects of Noise on Sleep;  • Effects on Performance and Behavior;  Albright Way Development Project   Acoustical Assessment 9 March 2011  • Extra‐Auditory Health Effects; and  • Annoyance.    Although it often causes discomfort and sometimes pain, noise‐induced hearing loss usually  takes years to develop.  Noise‐induced hearing loss can impair the quality of life through a  reduction in the ability to hear important sounds and to communicate with family and friends.   Hearing loss is one of the most obvious and easily quantified effects of excessive exposure to  noise.  While the loss may be temporary at first, it could become permanent after continued  exposure.  When combined with hearing loss associated with aging, the amount of hearing loss  directly caused by the environment is difficult to quantify.  Although the major cause of noise‐ induced hearing loss is occupational, substantial damage can be caused by non‐occupational  sources.    According to the United States Public Health Service, nearly ten million of the estimated 21  million Americans with hearing impairments owe their losses to noise exposure.  Noise can  mask important sounds and disrupt communication between individuals in a variety of  settings.  This process can cause anything from a slight irritation to a serious safety hazard,  depending on the circumstance.  Noise can disrupt face‐to‐face communication and telephone  communication, and the enjoyment of music and television in the home.  It can also disrupt  effective communication between teachers and pupils in schools, and can cause fatigue and  vocal strain in those who need to communicate in spite of the noise.    Interference with communication has proved to be one of the most important components of  noise‐related annoyance.  Noise‐induced sleep interference is one of the critical components of  community annoyance.  Sound level, frequency distribution, duration, repetition, and  variability can make it difficult to fall asleep and may cause momentary shifts in the natural  sleep pattern, or level of sleep.  It can produce short‐term adverse effects on mood changes and  job performance, with the possibility of more serious effects on health if it continues over long  periods.  Noise can cause adverse effects on task performance and behavior at work, and non‐ occupational and social settings.  These effects are the subject of some controversy, since the  presence and degree of effects depends on a variety of intervening variables.  Most research in  this area has focused mainly on occupational settings, where noise levels must be sufficiently  high and the task sufficiently complex for effects on performance to occur.      Recent research indicates that more moderate noise levels can produce disruptive after‐effects,  commonly manifested as a reduced tolerance for frustration, increased anxiety, decreased  incidence of “helping” behavior, and increased incidence of “hostile” behavior.  Noise has been  implicated in the development or exacerbation of a variety of health problems, ranging from  hypertension to psychosis.  As with other categories, quantifying these effects is difficult due to  the amount of variables that need to be considered in each situation.  As a biological stressor,  noise can influence the entire physiological system.  Most effects seem to be transitory, but with  continued exposure some effects have been shown to be chronic in laboratory animals.      Albright Way Development Project   Acoustical Assessment 10 March 2011  Annoyance can be viewed as the expression of negative feelings resulting from interference  with activities, as well as the disruption of one’s peace of mind and the enjoyment of one’s  environment.  Field evaluations of community annoyance are useful for predicting the  consequences of planned actions involving highways, airports, road traffic, railroads, or other  noise sources.  The consequences of noise‐induced annoyance are privately held dissatisfaction,  publicly expressed complaints to authorities, and potential adverse health effects, as discussed  above.  In a study conducted by the United States Department of Transportation, the effects of  annoyance to the community were quantified.  In areas where noise levels were consistently  above 60 dBA CNEL, approximately nine percent of the community is highly annoyed.  When  levels exceed 65 dBA CNEL, that percentage rises to 15 percent.  Although evidence for the  various effects of noise have differing levels of certainty, it is clear that noise can affect human  health.  Most of the effects are, to a varying degree, stress related.           Albright Way Development Project   Acoustical Assessment 11 March 2011  3.0 LAWS, ORDINANCES, REGULATIONS, AND STANDARDS    Land uses deemed sensitive by the State of California (State) include schools, hospitals, rest  homes, and long‐term care and mental care facilities.  Many jurisdictions also consider  residential uses particularly noise‐sensitive because families and individuals expect to use time  in the home for rest and relaxation, and noise can interfere with those activities.  Some  jurisdictions may also identify other noise‐sensitive uses such as churches, libraries, and parks.  Land uses that are relatively insensitive to noise include office, commercial, and retail  developments.  There is a range of insensitive noise receptors that include uses that generate  significant noise levels and that typically have a low level of human occupancy.      This noise analysis was conducted in accordance with Federal, State, and local criteria described  in the following sections.    3.1 U.S. ENVIRONMENTAL PROTECTION AGENCY    The U.S. Environmental Protection Agency (EPA) offers guidelines for community noise  exposure in the publication Noise Effects Handbook – A Desk Reference to Health and Welfare Effects  of Noise.  These guidelines consider occupational noise exposure as well as noise exposure in  homes.  The EPA recognizes an exterior noise level of 55 decibels day‐night level (dB Ldn) as a  general goal to protect the public from hearing loss, activity interference, sleep disturbance, and  annoyance.  The EPA and other Federal agencies have adopted suggested land use  compatibility guidelines that indicate that residential noise exposures of 55 to 65 dB Ldn are  acceptable.  However, the EPA notes that these levels are not regulatory goals, but are levels  defined by a negotiated scientific consensus, without concern for economic and technological  feasibility or the needs and desires of any particular community.    3.2 CALIFORNIA ENVIRONMENTAL QUALITY ACT    The California Environmental Quality Act (CEQA) was enacted in 1970 and requires that all  known environmental effects of a project be analyzed, including environmental noise impacts.   Under CEQA, a project has a potentially significant impact if the project exposes people to noise  levels in excess of standards established in the local general plan or noise ordinance.   Additionally, under CEQA, a project has a potentially significant impact if the project creates a  substantial increase in the ambient noise levels in the project vicinity above levels existing  without the project.  If a project has a potentially significant impact, mitigation measures must  be considered.  If mitigation measures to reduce the impact to less than significant are not  feasible due to economic, social, environmental, legal, or other conditions, the most feasible

policies for reducing noise levels in the Town.  Policies aimed at reducing noise levels must  address specific sources of unwanted noise, as well as noise‐sensitive receptors.  Noise level  generation, intensity, and related impacts should be considered in determining the placement of  housing, open space areas, and other noise‐sensitive land uses.      The State of California Office of Planning and Research Noise Element Guidelines (Guidelines) include  recommended interior and exterior noise level standards for local jurisdictions to identify and  prevent the creation of incompatible land uses due to noise.  These Guidelines describe the  compatibility of various land uses with a range of environmental noise levels in terms of dBA  CNEL, as explained in Table 1, above.      According to the State, a noise environment of 50 dBA CNEL to 60 dBA CNEL is considered to  be “normally acceptable” for residential uses.  Therefore, locating residential units, parks, and  institutions (such as churches, schools, libraries, and hospitals) in areas where exterior ambient  noise levels exceed 65 dBA CNEL is undesirable.  Additionally, more restrictive standards for  quiet suburban and rural communities may be reduced by 5 to 10 dB to reflect their lower  existing outdoor noise levels in comparison with urban environments.      Title 25, Section 1092 of the California Code of Regulations also sets forth requirements for the  insulation of multiple‐family residential dwelling units from excessive and potentially harmful  noise.  Whenever multiple‐family residential dwelling units are proposed in areas with  excessive noise exposure, the developer must incorporate construction features into the  building’s design that reduce interior noise levels to 45 dBA CNEL.    Table 2, Land Use Compatibility for Community Noise Environments, depicts the State guidelines  established by the State Department of Health Services for acceptable noise levels for each  jurisdiction.  These standards and criteria are incorporated into the land use planning process to  reduce future noise and land use incompatibilities.  These guidelines help the Town ensure  integrated planning for compatibility between land uses and outdoor noise.  Albright Way Development Project   Acoustical Assessment 13 March 2011  Table 2

insulation requirements. CONDITIONALLY ACCEPTABLE: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is made and needed noise insulation features have been included in the design. Conventional construction, but with closed windows and fresh air supply systems or air conditioning, will normally suffice. NORMALLY UNACCEPTABLE: New construction or development should be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise-insulation features must be included in the design. CLEARLY UNACCEPTABLE: New construction or development should generally not be undertaken.

Albright Way Development Project   Acoustical Assessment 18 March 2011  4.0  EXISTING CONDITIONS    4.1 NOISE MEASUREMENTS     In order to quantify existing ambient noise levels in the project area, RBF Consulting conducted  four noise measurements on December 3, 2010; refer to Table 4, Noise Measurements.  The noise  measurement sites were representative of typical existing noise exposure within and  immediately adjacent to the project site.  Ten‐minute measurements were taken, between 1:00  PM and 2:15 PM, at each site during the day.  Short‐term (Leq) measurements are considered  representative of the noise levels throughout the day and relate closely with the Town’s noise  standards which are expressed in Ldn.  Ldn values are calculated from hourly Leq values, with  penalties for the nighttime period (10:00 PM to 7:00 AM) to reflect the greater disturbance  potential from nighttime noise.  Noise sources in the project area (i.e., traffic and mechanical  equipment) become less active and generate less noise in the project area during the nighttime  period.  As a result, the variance between Leq and Ldn is typically less than one dBA in areas such  as the project site.      Meteorological conditions were clear skies, cool temperatures, with light wind speeds (0 to 5  miles per hour), and low humidity.  Measured noise levels during the daytime measurements  ranged from 52.3 to 67.4 dBA Leq.  Noise monitoring equipment used for the ambient noise  survey consisted of a Brüel & Kjær Hand‐held Analyzer Type 2250 equipped with a Type 4189  pre‐polarized microphone.  The monitoring equipment complies with applicable requirements  of the American National Standards Institute (ANSI) for Type I (precision) sound level meters.   The results of the field measurements are included in Appendix A, Noise Measurement Sheets.   Refer to Exhibit 5, Noise Measurement Locations for the noise measurements sites.      Table 4

In order to assess the potential for mobile source noise impacts, it is necessary to determine the  noise currently generated by vehicles traveling through the project area.  Noise models were  run using the Federal Highway Administration’s Highway Noise Prediction Model (FHWA‐ RD‐77‐108) together with several roadway and site parameters; please refer to Appendix B,  Modeling Data.  These parameters determine the projected impact of vehicular traffic noise and  include the roadway cross‐section (e.g., number of lanes), roadway width, average daily traffic  (ADT), vehicle travel speed, percentages of auto and truck traffic, roadway grade, angle‐of‐ view, and site conditions (“hard” or “soft”).  The model does not account for ambient noise  levels (i.e., noise from adjacent land uses) or topographical differences between the roadway  and adjacent land uses.      Noise projections are based on modeled vehicular traffic as derived from the Albright Way  Development Traffic Impact Analysis, prepared by Hexagon Transportation Consultants, Inc. on  March 17, 2011.  The posted speed limits are 35 miles per hour (mph) on Winchester Boulevard,  30 mph on Lark Avenue, and 25 mph on Wimbledon Drive.  Existing modeled traffic noise

HVAC units and off‐site residential uses.    Albright Way Development Project   Acoustical Assessment 22 March 2011  5.0 POTENTIAL ACOUSTICAL IMPACTS    CEQA THRESHOLDS  Appendix G of the CEQA Guidelines contains analysis guidelines related to the assessment of  noise impacts.  These guidelines have been utilized as thresholds of significance for this  analysis.  As stated in Appendix G, a project would create a significant environmental impact if  it would:      • Expose persons to, or generate noise levels in excess of standards established in the local  general plan or noise ordinance, or applicable standards of other agencies (refer to  Impact Statements NOI‐1);  • Expose persons to or generate excessive ground borne vibration or ground borne noise  levels (refer to Impact Statement NOI‐2);     • Result in a substantial permanent increase in ambient noise levels in the project vicinity  above levels existing without the project (refer to Impact Statement NOI‐1);    • Result in a substantial temporary or periodic increase in ambient noise levels in the  project vicinity above levels existing without the project (refer to Impact Statement NOI‐ 1);   • For a project located within an airport land use plan or, where such a plan has not been  adopted, within two miles of a public airport or public use airport, expose people  residing or working in the project area to excessive noise levels (refer to Impact  Statement NOI‐3); and    • For a project within the vicinity of a private airstrip, expose people residing or working  in the project area to excessive noise levels (refer to Impact Statement NOI‐3).    Based on these standards and thresholds, the effects of the proposed project have been  categorized as either a “less than significant impact” or a “potentially significant impact.”   Mitigation measures are recommended for potentially significant impacts.      SIGNIFICANCE OF CHANGES IN TRAFFIC NOISE LEVELS  If the ambient noise environment is quiet and the new noise source greatly increases the noise  exposure, an impact may occur even though a criterion level might not be exceeded.  The  project would create a significant impact for traffic noise levels when the following occurs:    • An increase of the existing ambient noise levels by 5 dBA or more, where the ambient  level is less than 60 dBA CNEL;   Albright Way Development Project   Acoustical Assessment 23 March 2011  • An increase of the existing ambient noise level by 3 dBA or more, where the ambient

SIGNIFICANCE OF CHANGES IN CUMULATIVE TRAFFIC NOISE LEVELS    The project’s contribution to a cumulative traffic noise increase would be considered  cumulatively considerable when the combined effect exceeds perception level (i.e., auditory  level increase) threshold.  The combined effect compares the “cumulative with project”  condition to “existing” conditions.  This comparison accounts for the traffic noise increase from  the project generated in combination with traffic generated by projects in the cumulative  projects list.  The following criteria have been utilized to evaluate the combined effect of the  cumulative noise increase.      Combined Effects:  The cumulative with project noise level (“Cumulative With Project”) causes  the following:    • An increase of the existing noise level by 5 dBA or more, where the existing level is less  than 60 dBA CNEL;  • An increase of the existing noise level by 3 dBA or more, where the existing level is 60 to  65 CNEL; or  • An increase of the existing noise level by 1.5 dBA or more, where the existing level is  greater than 65 dBA CNEL.    Although there may be a significant noise increase due to the proposed project in combination  with other related projects (combined effects), it must also be demonstrated that the project has  an incremental effect.  In other words, a significant portion of the noise increase must be due to  the proposed project.  The following criteria have been utilized to evaluate the incremental  effect of the cumulative noise increase.    Incremental Effects:  The “Cumulative With Project” causes a 1 dBA increase in noise over the  “Cumulative Without Project” noise level.    A significant impact would result only if both the combined and incremental effects criteria  have been exceeded.    NOI‐1     • EXPOSE PERSONS TO, OR GENERATE NOISE LEVELS IN EXCESS OF

NOISE LEVELS IN THE PROJECT VICINITY ABOVE LEVELS EXISTING  WITHOUT THE PROJECT?    Level of Significance Before Mitigation:  Potentially Significant.     Scenario 1    SHORT‐TERM CONSTRUCTION    Construction activities are generally temporary and short in duration, resulting in periodic  increases in the ambient noise environment.  Project construction would occur over six phases,  including demolition of existing buildings, site grading, trenching, paving, building  construction, and architectural coating.  Staging for construction equipment would occur within  the boundaries of the project site.  Groundborne noise and other types of construction‐related  noise impacts would typically occur during the initial site preparation, which can create the  highest levels of noise.  However, site preparation typically has the shortest duration of all  construction phases.  Activities that occur during this phase include demolition, earthmoving,  and soils compaction.  High groundborne noise levels and other miscellaneous noise levels can  be created during this phase due to the operation of heavy‐duty trucks, backhoes, and front‐end  loaders.  A reasonable worst‐case assumption is that the three loudest pieces of equipment  would operate simultaneously within a focused area and occur continuously over at least one  hour.      Table 7, Maximum Noise Levels Generated by Construction Equipment, indicates the anticipated  noise levels of construction equipment based on a distance of 50 feet between the equipment  and noise receptor.  It should be noted that the noise levels identified in Table 7 are maximum  sound levels (Lmax) which are the highest individual sound occurring at an individual time  period.  The Town’s noise ordinance limits construction noise to 85 dBA at the property line and  is based on the on the Ldn scale which is a noise level over a 24‐hour period.  The Lmax values  presented in Table 7 would be lower on the Ldn scale.  Operating cycles for these types of  construction equipment may involve one or two minutes of full power operation followed by  three or four minutes at lower power settings.  The site preparation phase, which includes  grading of the site, tends to generate the highest noise levels.  Albright Way Development Project

It should be noted that the TNM 2.5 model has a tolerance standard deviation of +/-0.5 dBA. 3. A 20 dBA noise attenuation rate was utilized to determine the interior noise standards.     Mobile noise sources may also occur from adjacent rail operations.  Past noise measurements  collected on properties to the west and north of the project site (also adjacent to SR‐85 and  Winchester Boulevard) indicate similar relationships between daytime Leq and Ldn.  Noise  measurements taken on the property west of the site also indicate that train operations on the  tracks along the west side of the site increase Ldn noise levels by up to 2 dBA in proximity to  the railroad tracks along Winchester Boulevard.  With train operations, noise levels could reach  70 dBA along the western site boundary on the days when train operations occur.  The planned  Vasona Light Rail Station would be located on Winchester Boulevard, approximately 550 feet to  the north of the site and SR‐85.  Since the route for the light rail train ends at this station and this  would be the closest distance between the site and these rail operations, noise from light rail  operations or the station is not expected to affect noise levels at the project site.    Using the future traffic volumes on Winchester Boulevard (between SR‐85 and Wimbledon  Drive) and the FHWA TNM 2.5 model, noise levels were estimated at eight potential receptor  locations on the site; refer to Table 10. The highest levels (58 to 65 dBA) would be located  adjacent to SR‐85, while future noise levels along Winchester Boulevard would be 55 to 62 dBA  without train operations and 55 to 64 dBA along Winchester Boulevard with train operations.  Standard building construction practices typically result in approximately 20 dBA of noise  attenuation with windows closed, which would result in interior noise levels of less than 45  dBA.  Therefore, noise impacts to on‐site sensitive uses (residents) from rail operations would  be less than significant.      As with Scenario 1, stationary noise sources associated with the Scenario 3 would include noise  from delivery truck loading and unloading, truck movements on driveways, and parking  lot/structure activities.  Noise impacts from these sources associated with office and residential  Albright Way Development Project   Acoustical Assessment 32 March 2011  uses would be infrequent and intermittent.  HVAC systems installed for the proposed office  uses would result in noise levels that average between 40 and 50 dBA Leq at 50 feet from the  equipment, which are within the Town’s noise standards.  Although Scenario 3 proposes a mix  of commercial and residential uses, the residential uses would be more than 50 feet from the  potential locations of the HVAC equipment based on distances required for building setbacks  and drive aisles.  Pursuant to Section 16 (Noise) of the Town’s Municipal Code, any new  stationary noise source would be required to provide adequate sound attenuation such that  Town noise standards are achieved.  This can be achieved through the use of HVAC silencers,  acoustical enclosures, and/or locating mechanical equipment away from sensitive receptors.   Compliance with the Town’s standards would reduce potential stationary source noise impacts  to less than significant levels.    On‐site stationary sources or activities would be shielded by on‐ and off‐site buildings,  vegetation, and traffic along adjacent streets and not occur at distances closer to any existing or  proposed residential uses in the project vicinity, noise associated with these stationary sources  would result in a less than significant impact.      Scenario 4    The development of Scenario 4 would result in a similar development plan as envisioned within  Scenario 3.  The primary difference would be that Scenario 3 proposes 516 high‐density units  instead of 600 senior units.  Although the proposed residential dwelling units would increase  by 84, impacts would not increase because Scenario 3 analyzed a worst‐case noise scenario  when modeling traffic noise impacts to on‐site residents.  At full development, Scenario 4  would result in 1,442 daily net new trips (as opposed to 2,000 for Scenario 3).   Thus, operational  noise impacts would be proportionately reduced.  Therefore, impacts would be less than  significant with the incorporation of the recommended mitigation.    Exposure of on‐site residents to noise from adjacent rail operations would be similar to that  described for Scenario 3.  Senior units would not be exposed to interior noise levels in excess of  45 dBA from rail operations.  Therefore, noise impacts to on‐site sensitive uses (senior unit  residents) from rail operations would be less than significant.      Stationary source noise generally produced in mixed‐use districts includes slow‐moving truck  deliveries, traffic in parking areas and equipment noise from landscape maintenance.  HVAC  systems installed for the proposed office uses would result in noise levels that average between  40 and 50 dBA Leq at 50 feet from the equipment.  As with Scenario 3, Scenario 4 proposes a mix  of commercial and residential uses.  The residential uses would be more than 50 feet from the  potential locations of the HVAC equipment due to requirements for building setbacks and drive  aisles.  On‐site buildings, adjacent streets, street trees, and vegetation would serve as a buffer  between the project site and nearby sensitive receptors.  Pursuant to Section 16 (Noise) of the  Town’s Municipal Code, these noise levels would not exceed the Town of Los Gatos’ exterior  noise standards.  Any new stationary noise source would be required to provide adequate  sound attenuation such that Town noise standards are achieved.  Impacts would be less than  significant.  Albright Way Development Project   Acoustical Assessment 33 March 2011  Mitigation Measures:      NOI‐1 Prior to Grading Permit issuance, the Contractor shall demonstrate, to the satisfaction of  the Town of Los Gatos Public Works Department that the project complies with the  following:    • Construction contracts specify that all construction equipment, fixed or mobile,  shall be equipped with properly operating and maintained mufflers and other  state required noise attenuation devices.    • Property occupants located adjacent to the project boundary shall be sent a notice,  at least 15 days prior to commencement of construction of each phase, regarding  the construction schedule of the proposed project.  A sign, legible at a distance of  50 feet shall also be posted at the project construction site.  All notices and signs  shall be reviewed and approved by the Town of Los Gatos Public Works  Department prior to mailing or posting and shall indicate the dates and duration  of construction activities, as well as provide a contact name and a telephone  number where residents can inquire about the construction process and register  complaints.    • The Contractor shall provide, to the satisfaction of the Town of Los Gatos Public  Works Department, a qualified “Noise Disturbance Coordinator.”  The  Disturbance Coordinator shall be responsible for responding to any local  complaints about construction noise.  When a complaint is received, the  Disturbance Coordinator shall notify the Town within 24‐hours of the complaint  and determine the cause of the noise complaint (e.g., starting too early, bad  muffler, etc.) and shall implement reasonable measures to resolve the complaint,  as deemed acceptable by the Public Works Department.  All notices that are sent  to residential units immediately surrounding the construction site and all signs  posted at the construction site shall include the contact name and the telephone  number for the Disturbance Coordinator.    • Construction haul routes shall be designed to avoid noise sensitive uses (e.g.,  residences, convalescent homes, etc.).    • During construction, stationary construction equipment shall be placed such that  emitted noise is directed away from sensitive noise receivers.    • Pursuant to the Town of Los Gatos Municipal Code Section 16.20.035, construction  activities shall occur between the hours of 8:00 AM and 8:00 PM on weekdays  and 9:00 AM and 7:00 PM on weekends and holidays.  Additionally, pursuant to  Municipal Code Section 16.20.035(2) the Contractor shall demonstrate, to the  satisfaction of the Town of Los Gatos Public Works Department, that construction  noise shall not exceed 85 dBA outside of the property line.  This shall be  accomplished with implementation of methods previously described in this  mitigation measure, above.  Albright Way Development Project   Acoustical Assessment 34 March 2011  Level of Significance After Mitigation:  Less Than Significant.    NOI‐2 EXPOSURE OF PERSONS TO OR GENERATION OF EXCESSIVE  GROUNDBORNE VIBRATION OR GROUNDBORNE NOISE LEVELS?    Level of Significance Before Mitigation:  Less Than Significant.     Scenario 1    Short‐Term (Construction) Impacts    Project construction can generate varying degrees of groundborne vibration, depending on the  construction procedure and the construction equipment used.  Operation of construction  equipment generates vibrations that spread through the ground and diminish in amplitude  with distance from the source.  The effect on buildings located in the vicinity of the construction  site often varies depending on soil type, ground strata, and construction characteristics of the  receiver building(s).  The results from vibration can range from no perceptible effects at the  lowest vibration levels, to low rumbling sounds and perceptible vibration at moderate levels, to  slight damage at the highest levels.  Groundborne vibrations from construction activities rarely  reach levels that damage structures.    The types of construction vibration impact include human annoyance and building damage.   Human annoyance occurs when construction vibration rises significantly above the threshold  of human perception for extended periods of time.  Building damage can be cosmetic or  structural.  Ordinary buildings that are not particularly fragile would not experience any  cosmetic damage (e.g., plaster cracks) at distances beyond 30 feet.  This distance can vary  substantially depending on the soil composition and underground geological layer between  vibration source and receiver.  In addition, not all buildings respond similarly to vibration  generated by construction equipment.  The vibration produced by construction equipment is  illustrated in Table 11, Typical Vibration Levels for Construction Equipment.    Table 11  Typical Vibration Levels for Construction Equipment  Equipment Approximate peak particle velocity at 25 feet (inches/second) Approximate peak particle velocity at 75 feet (inches/second) Large bulldozer 0.089 0.017 Loaded trucks 0.076 0.015 Small bulldozer 0.003 0.001 Notes: 1 - Peak particle ground velocity measured at 25 feet unless noted otherwise. 2 - Root mean square amplitude ground velocity in decibels (VdB) referenced to 1 micro-inch/second. Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Guidelines, May 2006.     Albright Way Development Project   Acoustical Assessment 35 March 2011  Groundborne vibration decreases rapidly with distance.  As indicated in Table 11, based on the  Federal Transit Administration (FTA) data, vibration velocities from typical heavy construction  equipment operation that would be used during project construction range from 0.003 to 0.089  inch‐per‐second peak particle velocity (PPV) at 25 feet from the source of activity.  At 75 feet  from the source activity, vibration velocities range from 0.001 to 0.017 inch‐per‐second peak  PPV.  With regard to the proposed project, groundborne vibration would be generated  primarily during site clearing and grading activities on‐site and by off‐site haul‐truck travel.   Although the closest occupied residential uses are located within 25 feet of the project site  (adjacent to the south), the proposed construction activities would not be capable of exceeding  the 0.2 inch‐per‐second PPV significance threshold for vibration.  Therefore, vibration impacts  would be less than significant.    Long‐Term (Operational) Impacts    The project site is located adjacent to the east of the Union Pacific Railroad (UPRR) alignment.   The freight operations along UPRR currently operate at or below what it did 10 years ago (three  times per week, twice per day).  The sharp turn across Winchester Boulevard requires freight  trains to reduce their speed significantly, which results in lower noise and vibration levels.   According to the Federal Transit System’s Transit Noise and Vibration Impact Assessment (April  1995), typical transit vibration levels are approximately 70 VdB at 50 feet, and heavy  locomotives average approximately five to 10 decibels higher than rail transit vehicles.   Therefore, freight operations adjacent to the project site to the west would result in vibration  levels of 75 to 80 VdB at 50 feet.  However, it is noted that the levels are expected to be lower  due to the sharp turn across Winchester Boulevard and the reduced speed of the trains.   According to the Federal Transit Administration (FTA) (Transit Noise and Vibration Impact  Assessment, May 2006) and Federal Railroad Administration (High‐Speed Ground Transportation  Noise and Vibration Impact Assessment, December 1998), vibration levels of 85 VdB are acceptable  if there are an infrequent number of events per day.  The FTA screening procedure for vibration  impacts in the Transit Noise and Vibration Impact Assessment applies to FTA‐assisted projects only  and is intended to apply only to transit and commuter rail with 30 or more vibration events per  day.  Therefore, as the proposed project does not FTA assistance and would not be exposed to  more than two vibration events per day, the FTA’s screening procedure does not apply.  As  freight trains pass by the project site very infrequently (up to three times per week, twice per  day), and the trains would not result in vibration levels exceeding 85 VdB, no significant  vibration impacts would occur.    Scenario 2    The development of Scenario 2 would result in less commercial office space than considered  under Scenario 1.  Construction related vibration impacts would be reduced due to the reduced  construction activities required.  Therefore, construction related activities associated with  Scenario 2 would not be capable of exceeding the 0.2 inch‐per‐second PPV significance  threshold at the residential uses to the south.  Operational vibration impacts from freight  operations along the adjacent UPRR alignment would be similar to those identified in  Albright Way Development Project   Acoustical Assessment 36 March 2011  Scenario 1.  As with Scenario 1, vibration impacts for Scenario 2 would be less than significant,  and no mitigation would be required.           Scenario 3    The development of Scenario 3 would result in less commercial office space than considered  under Scenario 1.   However, Scenario 3 also includes up to 516 high‐density units.  These high‐ density units could be developed and occupied while construction of the commercial  component is in progress.  However, the proposed residential units would not be within 25 feet  of the construction areas for the office uses.  Additionally, the majority of construction activities  would occur throughout the project site, and would not occur immediately adjacent to the  residential dwelling units.  Construction related vibration impacts would be similar to that  presented for Scenario 1.  Operational vibration impacts from freight operations along the  adjacent UPRR alignment would also be similar to those identified in Scenario 1.  Therefore, as  with Scenario 1, vibration impacts would be less than significant and no mitigation is required.      Scenario 4    The development of Scenario 4 would result in a similar development plan as envisioned within  Scenario 3.  The primary difference would be that Scenario 3 proposes 516 high‐density units  instead of 600 senior units.  As a result, construction related vibration impacts would be similar  to that presented for Scenario 1 and Scenario 3.  No significant construction activity associated  with construction of the proposed office uses would occur within 25 feet of any previously  developed senior units on‐site.  Additionally, the majority of construction activities would occur  throughout the project site, and would not occur immediately adjacent to the residential  dwelling units.  Therefore, construction vibration impacts would be less than significant and no  mitigation is required.    Operational vibration impacts from freight operations along the adjacent UPRR alignment  would be similar to those identified in Scenario 1.  Therefore, vibration impacts would be less  than significant and no mitigation is required.    Mitigation Measures:  No mitigation measures are required.    Level of Significance After Mitigation:  Not Applicable.    NOI‐3     • FOR A PROJECT LOCATED WITHIN AN AIRPORT LAND USE PLAN OR,

NOISE LEVELS?    Level of Significance Before Mitigation:  Less Than Significant.     Scenario 1    The proposed project is not located within an airport land use plan.  There is no public airport,  public use airport, or private airstrip located within the Town’s boundaries or within two miles  of the project site.  For air travel, the closest international airports are San Jose International  Airport (SJC), San Francisco International Airport (SFO), and Oakland International Airport.   The proposed project would not expose people residing or working in the area to excessive  noise levels.  Therefore, impacts in this regard would be less than significant.    Scenario 2    Development of Scenario 2 would not change the location of the project site.  There is no public  or private airport within two miles of the project site and Scenario 2 would not expose people to  excessive noise levels.  Therefore, impacts would be less than significant in this regard.     Scenario 3    Development of Scenario 3 would not expose people to excessive noise levels, as there is no

Development of Scenario 4 would not expose people to excessive noise levels.  There is no  public or private airport within two miles of the project site and Scenario 4.  Therefore, impacts  would be less than significant in this regard.     Mitigation Measures: No mitigation measures are required.    Level of Significance After Mitigation:  Not Applicable.    Albright Way Development Project   Acoustical Assessment 38 March 2011  CUMULATIVE IMPACTS    Level of Significance Before Mitigation:  Less Than Significant.     Scenario 1    Cumulative Operational Noise    Scenario 1 would introduce the use of stationary equipment that would increase noise levels  within the area.  Based on the long‐term stationary noise impacts analysis above under Impact  NOI‐1, impacts would be less than significant.  Additionally, Scenario 1 would not result in  stationary long‐term equipment that would significantly affect surrounding sensitive receptors.   Furthermore, future development proposals, other than the project, within the Town would  require separate discretionary approval and CEQA assessment, which would address potential  noise impacts and identify necessary attenuation measures, where appropriate.  Thus,  cumulative noise exposure for long‐term operations would result in a less than significant  impact.       Cumulative Mobile Noise    The cumulative condition is defined as the background conditions plus pending (but not yet  approved) project trips.  The cumulative mobile noise analysis is conducted in a two step  process.  First, the combined effects from both the proposed project and other projects are  compared.  Second, for combined effects that are determined to be cumulatively significant, the  project’s incremental effects then are analyzed.  The project’s cumulatively considerable  contribution to a cumulative traffic noise increase would be considered significant when the  combined effect exceeds perception level (i.e., auditory level increase) threshold.  The combined  effect compares the “cumulative with project” condition to “existing” conditions.  This  comparison accounts for the traffic noise increase from the project generated in combination  with traffic generated by projects in the cumulative projects list.  The following criteria have  been utilized to evaluate the combined effect of the cumulative noise increase.    Combined Effects:  The cumulative with project noise level (“Cumulative With Project”) causes  the following:    • An increase of the existing noise level by 5 dBA or more, where the existing level is less  than 60 dBA CNEL;  • An increase of the existing noise level by 3 dBA or more, where the existing level is 60 to  65 dBA CNEL; or  • An increase of the existing noise level by 1.5 dBA or more, where the existing level is  greater than 65 dBA CNEL.    Albright Way Development Project   Acoustical Assessment 39 March 2011  Although there may be a significant noise increase due to the proposed project in combination  with other related projects (combined effects), it must also be demonstrated that the project has  an incremental effect.  In other words, a significant portion of the noise increase must be due to  the proposed project.  The following criteria have been utilized to evaluate the incremental  effect of the cumulative noise increase.    Incremental Effects:  The “Cumulative With Project” causes a 1 dBA increase in noise over the  “Cumulative Without Project” noise level.    A significant impact would result only if both the combined and incremental effects criteria  have been exceeded.    Noise by definition is a localized phenomenon, and drastically reduces as distance from the  source increases.  Consequently, only proposed projects and growth due to occur in the general  vicinity of the project site would contribute to cumulative noise impacts.  Table 12, Cumulative  Noise Scenario, lists the traffic noise effects along roadway segments in the project vicinity for  “Existing,” “Cumulative Without Project,” and “Cumulative With Project,” including  incremental and net cumulative impacts.    First, it must be determined whether the Cumulative With Project Increase Above Existing  Conditions (Combined Effects) is exceeded.  Per Table 12, this criteria is not exceeded.     Under the Incremental Effects criteria, cumulative noise impacts are defined by determining if the  ambient (“Cumulative Without Project”) noise level is increased by 1 dBA or more.  Per Table  12, this criteria is not exceeded.    Based on the results of Table 12, the maximum noise increase for combined effects criteria  would be 1.8 dBA and 0.8 dBA for incremental effects criteria.  Under the “Cumulative With  Project” scenario noise levels at a distance of 100 feet from the centerline for Lark Avenue,  between Winchester Boulevard and Oka Road are 62.2 dBA, which is below the Town’s  standard of 65 dBA for residential exterior land uses.  Furthermore, there would not be any  roadway segments that would result in significant impacts, as they would not exceed the  combined and incremental effects criteria.  Therefore, the proposed project, in combination with  cumulative background traffic noise levels, implementation of recommended mitigation  measures, and compliance with Town noise standards, would not result in a cumulatively  considerable contribution to noise in the area.  Impacts in this regard would be less than  significant.    Albright Way Development Project   Acoustical Assessment 40 March 2011  Table 12
