MEMORANDUM
Date May 21, 2025
To Ryan Safty, Associate Planner, Town of Los Gatos
From Patrick Kallas, Project manager
Akoni Danielsen, Principal Project Manager/President
Subject La Rinconada Country Club Redesign – CEQA Categorical Exemption Qualification
I. Introduction to Categorical Exemptions
The California Environmental Quality Act (CEQA) Guidelines contain classes of projects that have
been determined not to have a significant effect on the environment and are, therefore, exempt
from the provisions of CEQA. CEQA Guidelines Sections 15301 – 15333 constitute the list of
categorically exempt projects and contain specific criteria that must be met in order for a project to
be found exempt. CEQA Guidelines Section 15301, Existing Facilities Class 1 Categorical Exemptions,
and 15302, Replacement or Reconstruction Class 2 Categorical Exemptions set forth conditions for
projects which replace or reconstruct existing facilities that may be found categorically exempt.
Additionally, CEQA Guidelines Section 15300.2 includes a list of exceptions to exemptions, none of
which may apply to a project in order for it to qualify for a categorical exemption (i.e., if an
exception applies, a project is precluded from being found categorically exempt).
The Town of Los Gatos, serving as the Lead Agency, is completing environmental review for the La
Rinconada Country Club Modernization project (“project”) in compliance with CEQA, the CEQA
Guidelines (California Code of Regulations Section 15000 et. seq.), and the regulations and policies
of the Town of Los Gatos. This Memorandum describes the proposed project and provides analysis
and evidence to support a determination by the Town of Los Gatos that the project would be
eligible for a Categorical Exemption under CEQA.
II. Existing Conditions
La Rinconada Country Club was founded by A.P. Giannini in 1928. The first nine holes were
completed in 1928 and the second nine later in 1929. Since 1929, modest improvements have been
made to the golf course. The Country Club property is accessed by a driveway connecting to
Clearview Drive. This access point leads into a 171-space parking lot which serves the clubhouse,

country club facilities and golf course. The country club, including the golf course and associated
amenities, covers approximately 118.4 acres and is surrounded by residential neighborhoods. The
country club also borders the Rinconada Water Treatment Plant on the west. The location and
extent of the project area can be seen in Figure 1, 2, and 3.

III.Project Description
Proposed Golf Course Modernization
The proposed project would modernize the 18-hole layout and replant the entire course by
replacing fairways with more drought tolerant Bermuda grasses, adding native drought tolerant
trees, and installing a more efficient irrigation system. The adjusted course layout would leave 17 of
the 18 holes in their current locations. The only hole location that would be modified would be the
13th hole which would be slightly reoriented on the south side of the project site. All existing on-
site structures would remain unchanged and no changes are proposed for the driving range,
clubhouse, pool/fitness center, parking area, or maintenance facility. Minimal above grade work is
planned other than a slight realignment of the entrance drive to improve safety with golf play and a
small, approximately 250 square foot, restroom facility for the back 9 holes. Upon project
completion, the Country Club would continue to operate one 18-hole golf course on the property
and the membership numbers would remain unchanged. The proposed project would not expand
or increase the use of any facilities at La Rinconada Country Club. The proposed project would not
alter ingress and egress to the property.
Irrigation System and Cart Paths
As part of the proposed project, the irrigation system would be modernized, on-site drainage
systems would be upgraded, and the fairway grass would be replaced with a modern hybrid
Bermuda grass that requires 30-35 percent less irrigation water than the current course grass which
would reduce irrigation water consumption to approximately 30 million gallons per year. In addition
to the turf change and drainage upgrades, the proposed project would replace most of the existing
golf course cart paths with reduced footprint cart paths. Replacement of the cart paths would
reduce impervious surfaces on the golf course by approximately 70 percent.
Tree Removal
There are approximately 1,200 trees on the property, most of which are non-native species planted
by the Club over the past 50 years. Recently introduced coast redwoods and eucalyptus trees
would be replaced by native oaks as a part of the proposed project. The plan would remove
approximately 240 trees, most of which are redwoods and eucalyptus. The proposed project would
replace the trees removed at a one-to-one ratio, planting approximately 1ϳϯnative tree species on
the golf course and payment of in-lieu fees for the remaining tree replacement. Most of the trees
proposed for removal are on the interior of the course; only approximately 30 are on the perimeter
near homes. This would restore the property to a more natural state similar to the late 1920’s.
Construction
As part of construction activities, grading would be balanced on-site with approximately 52,780
cubic yards of cut and fill. The area of disturbance is shown in Figure 4, Project Disturbance Area. No
7
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
soil would be imported to or exported from the site. Construction of the proposed project is
estimated to take approximately seven to eight months to complete and is scheduled to begin in
early March of 2026. The proposed project would implement standard soil management
procedures to limit dust and debris on and around the project site, refer to Condition of Approval in
Section IV.(c), Air Quality Effects, below. Construction equipment and materials would be staged on
site and construction works would park on site as well during construction.

IV. Environmental Review
The purpose of this section is to document whether any of the exceptions listed in CEQA Guidelines
Section 15300.2 apply to the project, and assess the project’s eligibility for a Categorical Exemption
from CEQA under Section 15301, Existing Facilities Class 1 Categorical Exemptions, and 15302,
Replacement or Reconstruction Class 2 Categorical Exemptions.
Section 15300.2 – Exceptions
(a) Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be
located – a project that is ordinarily insignificant in its impact on the environment may in a
particularly sensitive environment be significant. Therefore, these classes are considered to
apply all instances, except where the project may impact on an environmental resource of
hazardous or critical concern where designated, precisely mapped, and officially adopted
pursuant to law by federal, state, or local agencies.
This exception only applies to Class 3, 4, 5, 6, and 11 exemptions. The proposed project is
categorically exempt under Class 1 and/or Class 2; therefore, this exception is not applicable to the
project under CEQA Guidelines Section 15300.2(a).
(b) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative
impact of successive projects of the same type in the same place, over time is significant.
The La Rinconada Country Club has undergone minor revisions for the last 100 years since it was
constructed. The timing of these changes has not been close chronologically, therefore, the impacts
associated with each modification to the country club would be far enough apart in time to not
compound with prior projects. Additionally, the La Rinconada Country Club does not anticipate
additional renovations in the near future which may result in cumulative impacts. For these
reasons, the proposed modernization of the La Rinconada Country Club would not result in
cumulative impacts.
(c) Significant Effect. A categorical exemption shall not be used for an activity where there is a
reasonable possibility that the activity will have a significant effect on the environment due to
unusual circumstances.
Air Quality Effects
The information in this section is based in part on the Construction Emissions and Health Risk
Assessment completed by Illingworth & Rodkin, Inc. This report, which evaluates project emissions
to confirm the project complies with General Plan Policy ENV-8.1: Air Quality Standards noted
below, is included for reference as Appendix A of the document.
The Town of Los Gatos has the following General Plan policies that are applicable to the project.
10
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
Policy ENV-8.1: Air Quality Standards. Federal, State, and regional air quality goals, policies,
standards, and requirements shall be addressed during environmental review for local land use and
development decisions. Applicable standards or requirements, if not already in the proposed plans,
shall be incorporated as conditions of approval.
Policy ENV-8.9: Air Pollution Impacts During Construction. Require project proponents to prepare
and implement a construction management plan that incorporates Best Available Control Measures
and all best management practices in accordance with the Air District standards to reduce criteria
pollutants.
General Plan Policy ENV-8.9: Include Bay Area Air Quality Management District (BAAQMD) basic
BMPs to control dust and exhaust during construction. During any construction period ground
disturbance, the applicant shall ensure that the project contractor implement measures to control
dust and exhaust. Implementation of the measures recommended by BAAQMD and listed below
would reduce the air quality impacts associated with grading and new construction to a less-than-
significant level.
x All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved
access roads) shall be watered two times per day.
x All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
x All visible mud/dirt track-out onto adjacent public roads shall be removed using wet power
vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
x All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).
x All roadways, driveways, and sidewalks to be paved shall be completed as soon as
practicable. Building pads shall be laid as soon as practicable after grading unless seeding or
soil binders are used.
x All excavation, grading, and/or demolition activities shall be suspended when average wind
speeds exceed 20 mph.
x All trucks and equipment, including their tires, shall be washed off prior to leaving the site.
x Unpaved roads providing access to site located 100 feet of further from a paved road shall
be treated with a six - to 12-inch layer of compacted layer of wood chips, mulch, or gravel.
Air Quality Construction Emissions
Based on the Construction Emissions and Health Risk Assessment, air pollutant emissions associated
with project construction were predicted using appropriate computer models. In addition, potential
project construction health risk impacts and the impact of existing toxic air contaminant (TAC)
sources affecting the existing nearby sensitive receptors (e.g., residents) were evaluated. The air
pollutants associated with the construction period include reactive organic gases (ROG), nitrogen
oxides (NOx), and particulate matter from exhaust (PM2.5 and PM10). The analysis was conducted
following guidance provided by the BAAQMD, the results of which are summarized below in Table
1.
11
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
The proposed project would require approximately seven months of grading and excavation work
(161 days) that would disturb 87.76 acres of ground area. Construction activities would require the
operation of heavy construction machinery and would disturb uncovered soil which would create
air quality contaminants for the entirety of the construction period. Average daily construction
emissions were estimated for the proposed project based on the equipment and operations
required for the project. These are summarized in Table 1 below.

Source: Illingworth& Rodkin, Inc. La Rinconada Country Club Redesign Construction Emissions & Health Risk
Assessment. February 7, 2025
Based on the emissions expected for the proposed project, the construction activities would not
exceed BAAQMD air quality impact thresholds for criteria air pollutants, and therefore the project
complies with Policy ENV-8.1, noted above. The proposed project, like virtually all projects which
involve ground disturbance, would also generate dust in the form of PM10 and PM2.5 through
disturbance and hauling of soils around the site. The project would implement the following
Condition of Approval to comply with Policy ENV-8.9 which requires standard best management
practices to limit fugitive dust pollutants.
Condition of Approval
During any construction period ground disturbance, the applicant shall ensure that the project
contractor implements measures to control dust and exhaust. Implementation of the measures
recommended by BAAQMD and listed below would reduce the air quality impacts associated with
grading and new construction to a less-than-significant level.
x All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved
access roads) shall be watered two times per day.
x All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
x All visible mud/dirt track-out onto adjacent public roads shall be removed using wet power
vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
x All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).
12
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
x All roadways, driveways, and sidewalks to be paved shall be completed as soon as
practicable. Building pads shall be laid as soon as practicable after grading unless seeding or
soil binders are used.
x All excavation, grading, and/or demolition activities shall be suspended when average wind
speeds exceed 20 mph.
x All trucks and equipment, including their tires, shall be washed off prior to leaving the site.
x Unpaved roads providing access to site located 100 feet of further from a paved road shall
be treated with a six - to 12-inch layer of compacted layer of wood chips, mulch, or gravel.
x Publicly visible signs shall be posted with the telephone number and name of the person to
contact at the lead agency regarding dust complaints. This person shall respond and take
corrective action within 48 hours. The Air District’s General Air Pollution Complaints number
shall be visible to ensure compliance with applicable regulations.
Therefore, the proposed project would not exceed BAAQMD thresholds for criteria pollutants or
fugitive dust and, by implementing the standard measures in Policy ENV-8.9, would have a less than
significant effect.
Air Quality Health Risk Effects
During construction of the proposed project the increase in diesel particulate matter (DPM) and
other PM2.5 can result in increased lifetime cancer risk and other health hazards. The construction
health risks were modeled for their impacts on existing residences surrounding the site and Roxbury
Elderly Care, located west of the site near the northern edge of the golf course. The effects were
modeled for impacts on all receptor types (i.e., third trimester, infants, children, and adults). The
total modeled DPM was calculated to be 0.04 tons and the fugitive dust was found to be less than
0.01 tons. Based on the modeling conducted for these emissions, the expected construction risk
impacts are shown in Table 2 below.

Based on the health risks associated with the project at the most sensitive receptor, the proposed
project would not exceed BAQQMD thresholds, and accordingly, would comply with Policy ENV-8.1,
and the project would have a less than significant health risk effect.
Noise and Vibration Effects
The information in this section is based in part on the Construction Noise and Vibration Assessment
completed by Illingworth & Rodkin, Inc. This report is included for reference as Appendix B of the
document.
Noise Effects
The Town of Los Gatos Code of Ordinances Section 16.20.035 limits construction activities to the
hours of 8:00 am to 6:00 pm on weekdays and between the hours of 9:00 am and 4:00 pm on
Saturdays. No construction is permitted on Sundays or holidays. Section 16.20.035 also states that
at least one of the following conditions shall be met:
x construction noise limits of 85 dBA at a distance of 25 feet for any single piece of equipment
and
x noise level at any point outside of the property plane of the project site is limited to 85 A-
weighted sound level (dBA)
Construction of the proposed project is estimated to take approximately seven to eight months to
be completed, beginning in March of 2026. Construction would progress across the country club
from hole to hole, and only portions of the property will experience construction activity at any
single point in time. In general, the construction activity would last approximately two to four
weeks per hole, depending on where the hole is located. The proposed hours of construction are
8:00 am to 6:00 pm on weekdays and 9:00 am to 4:00 pm on Saturdays. No construction would
occur on Sundays or holidays.
The construction activities that would be a part of the proposed project include earth-moving
activities with heavy equipment and hauling of primarily landscape construction materials. Based on
this activity, the proposed project would be expected to generate maximum noise levels of 70 to 90
dBA at a distance of 50 feet. A summary of the expected noise levels at receptors within 25 feet of
the construction activities is summarized below in Table 3.

Noise and Vibration Assessment. January 30, 2025
As shown in Table 3, average construction noise levels would range from 87 to 88 dBA Leq when the
two loudest pieces of construction equipment operate simultaneously, 25 feet from an individual
receptor. These predicted noise levels represent worst-case conditions, and under these conditions,
noise levels would be reduced to 84 to 85 dBA Leq if the two loudest pieces of construction
equipment per phase operate 35 feet or further from sensitive receptors. Therefore, the
construction would conflict with the policy requirement to keep noise below 85 dBA outside the
property plane as some places on the 8th, 16th, and 18th holes for the golf course if the two loudest
pieces of equipment were operating simultaneously. Therefore, with the following conditions of
approval, included in the project, the proposed project would further reduce noise effect during
construction. These actions are standard construction measures applied to most construction
projects in urban areas.
Conditions of Approval
x Construction activities shall be limited to the hours of 8:00 a.m. to 6:00 pm on weekdays
and between the hours of 9:00 am and 4:00 pm on Saturdays. No construction is permitted
on Sundays or holidays.
x Equip all internal combustion engine-driven equipment with intake and exhaust mufflers
that are in good condition and appropriate for the equipment.
x Prohibit unnecessary idling of internal combustion engines.
x Locate stationary noise-generating equipment, such as air compressors or portable power
generators, as far as possible from sensitive receptors as feasible. If they must be located
near receptors, adequate muffling (with enclosures where feasible and appropriate) shall be
used to reduce noise levels at the adjacent sensitive receptors. Any enclosure openings or
venting shall face away from sensitive receptors.
15
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
x Locate construction staging areas at locations that will create the greatest distance between
the construction-related noise sources and noise-sensitive receptors nearest the project site
during all project construction.
x Locate material stockpiles, as well as maintenance/equipment staging and parking areas, as
far as feasible from residential receptors.
x Designate a "disturbance coordinator" who would be responsible for responding to any
complaints about construction noise. The disturbance coordinator will determine the cause
of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be
implemented to correct the problem. Conspicuously post a telephone number for the
disturbance coordinator at the construction site and include in it the notice sent to
neighbors regarding the construction schedule.
The implementation of these reasonable controls would minimize disturbance at existing noise-
sensitive receptors in the project vicinity. Additionally, the majority of residences adjacent to the
project site are set back further than 35 feet from any work areas and only a small area of the back
yards would be exposed to elevated noise levels near the 8th, 16th, and 18th holes for the golf
course. Considering that the construction activity would last approximately two to four weeks per
hole, and less than one construction season in total, and that the majority of construction would
occur more than 35 feet from nearby receptors, the potential temporary exceedances of the Town’s
Code of Ordinances for a single piece of equipment over 85 dBA would result in a less than
significant effect.
Vibration Effect
The California Department of Transportation (Caltrans) recommends a vibration limit of 0.5 in/sec
peak particle velocity (PPV) for new residential and modern commercial/industrial structures, a
vibration limit of 0.3 in/sec PPV for older residential structures, and a vibration limit of 0.25 in/sec
PPV for historic buildings. The Town of Los Gatos recognizes a structure as historic if any one of the
following apply:
x Any structure / site that is located within a historic district
x Any structure / site that is historically designated within the LHP overlay
x Any primary structure constructed prior to 1941, unless the Town has specifically
determined the structure has no historic significance or architectural merit.
Based on the Town’s definition of historic structures, this analysis uses a vibration limit of 0.25
in/sec PPV to conservatively assess the potential for vibration impacts because the clubhouse and
homes in the surrounding area could be old enough, i.e. prior to 1941, to be considered historic
structures.
Based on the construction equipment planned to be used for the proposed project, the vibratory
levels in Table 4 would be expected.

Source: Illingworth& Rodkin, Inc. La Rinconada Country Club Golf Course Modernization Project Construction
Noise and Vibration Assessment. January 30, 2025
The proposed project could exceed vibratory impact levels if vibratory rollers are used within 20
feet of vibration sensitive buildings built before 1941. To reduce any potential vibration effects the
following Conditions of Approval are expected for the proposed project.
Condition of Approval
x Smaller equipment (less than 18,000 pounds) shall be used near the property lines adjacent
to the residential buildings to minimize vibration levels. For example, a smaller vibratory
roller similar to a Caterpillar model CP433E vibratory compactor could be used when
compacting materials within 25 feet of vibration-sensitive buildings.
x Small tractors/loaders/backhoes shall be used within 10 feet of vibration-sensitive buildings
instead of excavators.
x Designate a Disturbance Coordinator responsible for registering and investigating claims of
excessive vibration. The contact information of such person shall be clearly posted on the
construction site.
Based on the distance of residential structures from the edge of the golf course and the location of
construction activities on the project site, the vibratory equipment would not be used for long
periods of time near any structure which could be damaged by vibration along the 8th, 16th, and 18th
holes of the golf course. Therefore, by implementing the best management practices above,
primarily around the clubhouse area, the proposed project would result in less than significant
vibratory effect during construction.
Biological Effects
The proposed project would disturb up to approximately 87.76 acres of vegetated areas landscaped
for use as a golf course. This includes non-native grasses covering a majority of the area and trees
lining the golf course hole boundaries. The site is not mapped as habitat for special status plants or
17
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
animals, and does not contain regulated habitats, i.e. riparian areas or wetlands or waters of the US
or the state, as the ornamental ponds are man-made features subject to regular irrigation and
maintenance. The proposed project would remove and replace this landscaping which would
disturb any animals that are using the trees or other landscaped areas as habitat. Additionally, the
proposed project would be required to comply with the Tree Replacement Standards identified in
Table 3-1 of the Town of Los Gatos Zoning Regulations.
The proposed project would remove up to 240 trees across the golf course area. The full list of trees
removed as a part of the project is included in Appendix C. To protect birds that may be nesting in
the trees, the project would implement standard nesting survey requirements as required by the
Migratory Bird Treaty Act and California Department of Fish and Wildlife Code. These requirements
are summarized below. Through inclusion of this standard condition of approval the project would
avoid negative effects on birds.
Condition of Approval
x Construction shall be scheduled to avoid the nesting season to the extent feasible. The
nesting season for most birds, including most raptors, in the San Francisco Bay Area extends
from February 1st through August 31st.
If it is not possible to schedule construction and tree removal between September 1 and
January 31, then pre-construction surveys for nesting birds shall be completed by a qualified
ornithologist to ensure that no nests are disturbed during project implementation. This
survey shall be completed no more than 14 days prior to the initiation of grading, tree
removal, or other construction activities during the early part of the breeding season
(February through April) and no more than 30 days prior to the initiation of these activities
during the late part of the breeding season (May through August).
During this survey, the ornithologist shall inspect trees and other possible nesting habitats
within and immediately adjacent to the construction area for nests. If an active nest is found
sufficiently close to work areas to be disturbed by construction, the qualified ornithologist,
in consultation with California Department of Fish and Wildlife (CDFW), shall determine the
extent of a construction-free buffer zone to be established around the nest to ensure that
raptor or migratory bird nests shall not be disturbed during project construction.
(d) Scenic Highways. A categorical exemption shall not be used for a project which may result in
damage to scenic resources, including but not limited to, trees, historic buildings, rock
outcroppings, or similar resources, within a highway officially designated as a state scenic
highway. This does not apply to improvements which are required as mitigation by an adopted
negative declaration or certified EIR.
18
1871 The Alameda, Suite 200 x San José, CA 95126 x Tel: (408) 248-3500 x www.davidjpowers.com
There are no officially designated state scenic highways in the project area. The nearest officially
designated state highway is State Route 9, which is located approximately 1.25 miles southwest of
the project site and is not visible from the project site.1 The project, therefore, would not damage
scenic resources within a highway officially designated as a state scenic highway, and no exception
to the exemption applies under 15300.2(d).
(e) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site
which is included on any list compiled pursuant to Section 65962.5 of the Government Code.
The provisions in California Government Code Section 65962.5 are commonly referred to as the
“Cortese List”. Properties considered to be on the Cortese List include current and closed leaking
underground storage tank (LUST) case sites, in addition to sites with other hazardous conditions.
The California Government Code does not provide a provision for the removal of an affected
property from the Cortese List. Therefore, even properties with closed LUST cases in which no
further work is required are still considered to be on the Cortese List.
The project site is recorded on the Cortese List Geotracker database for two closed LUST cases,
which are associated with an area of the site in which no work is proposed. Due to the case closure,
and to confirm if there are any hazards present on the portion of the site where the proposed golf
course modernization would occur, Cornerstone Earth Group prepared a memorandum to evaluate
the status of the closed LUST cases and the potential for the proposed project to disturb areas
covered by the closed LUST cases.2
Based on the case information, a 500-gallon gasoline underground storage tank (UST) was removed
from the Site in 1993. In 1998, an additional 500-gallon diesel UST and a 1,000-gallon gasoline UST
were removed. All three USTs were located at the golf course maintenance facility on the furthest
southern portion of the project site, a small triangular area southeast of the 16th and 17th holes that
is not included within the area of proposed modernization work.
As a part of the case closure, sampling was conducted at the location of each of the three USTs. Soil
and groundwater samples detected only low concentrations of petroleum hydrocarbons, diesel
range petroleum hydrocarbons, and xylene. These detected concentrations did not exceed current
residential or commercial environmental screening levels (ESLs). The associated LUST cases were
closed by the Santa Clara Valley Water District (SCVWD) in 1997 and 1998.
While the LUST cases technically remain on the Cortese list for record keeping, the maintenance
facility area which includes the area of the closed LUST cases, is not part of the golf course
renovation plan. In addition, based on the Grading Plan, no earthwork activities are planned near

the maintenance facility area and former UST locations at the golf course maintenance facility.
Thus, the former UST locations should not have an adverse impact on the planned golf course
renovation work, and no exception to the exemption applies under 15300.2, as there are no current
conditions affecting the property that warrant inclusion on the Cortese list.3
(f) Historical Resources. A categorical exemption shall not be used for a project which may cause a
substantial adverse change in the significance of a historical resource.
The project site is a country club which was established in 1928, approximately 97 years ago. The
golf course was modified in 1989, including reconstruction of greens, replanting of grasses,
regrading of some fairways, and changes to drainage of the course. The property is not included on
the California Register of Historic Places, nor has it been determined eligible for listing on the
California Register by the State Historical Resources Commission. The country club is also not
identified in the Los Gatos General Plan as a registered historic place, nor has it been identified by
the County of Santa Clara in its historic register as a historic property. Therefore, the property is not
considered a mandatory historic resource under Guidelines Section 15064.5(a)(1) or a presumptive
historic resource under Section 15064.5(a)(2).
The proposed project would primarily replace the grass and some trees on the project site and
would only require the relocation of one golf hole for the country club. This improvement would be
similar to the improvements conducted in the 1990’s and would not change any of the uses of the
country club facilities. No physical changes are proposed to the clubhouse or any other structures.
Therefore, given the property is not listed as a historic resource by the state, county, or Town of Los
Gatos, the modifications proposed as a part of the modernization project would not create a
change in the significance of any historic resource.
Section 15301 – Existing Facilities
Section 15301, or Class 1, applies to projects consisting of the operation, repair, maintenance,
permitting, leasing, licensing, or minor alteration of existing public or private structures,
facilities, mechanical equipment, or topographical features, involving negligible or no expansion
of existing or former use. The key consideration is whether the project involves negligible or no
expansion of use. These conditions, along with the project’s consistency with them, are described
below.
The proposed modernization project would encompass grading of the site and reconstruction of the
golf course which would reduce the water consumption on-site and allow for greater water
infiltration due to reduced impervious surfaces. The changes to the golf course area would not
expand the number of players, the frequency or magnitude/intensity of events, or overall utility of
the project site. Therefore, the proposed project would not result in an expansion of use and would

only perform minor alteration of the existing facility and would meet the requirements for a Section
15301 exemption.
Section 15302 – Replacement and Reconstruction
Section 15302, or Class 2, applies to projects consisting of replacement or reconstruction of
existing structures, facilities where the new structure will be located on the same site as the
structure replaced and will have substantially the same purpose and capacity as the structure
replaced. These conditions, along with the project’s consistency with them, are described below.
The proposed project would regrade the golf course area of the project site and reorganize the golf
course layout. The reorganization of the site would construct the same uses within the existing
boundary of the facilities of the country club. Additionally, the proposed project would not alter any
of the structures on site other than a minor realignment of the primary access road for the project
site and a new 250-square foot bathroom structure in the middle of the course. Therefore, the
proposed project would be consistent with the conditions for a Section 15302 exemption because
the country club would replace the existing course area in kind, and would not change the purpose
or capacity of the La Rinconada Country Club.
V. Conclusion
As documented in Section IV. Environmental Review, with the incorporation of the City’s standard
conditions of approval, none of the exceptions contained in CEQA Guidelines Section 15300.2 apply
to the project and the project is consistent with the criteria in CEQA Guidelines Section 15301 and
15302. The project, therefore, qualifies as exempt from the provisions of CEQA under Class 1 and
Class 2 of the CEQA Guidelines.

SUBJECT:La Rinconada Country Club Redesign Project Biological Constraints Assessment
1.0 PURPOSE
The purpose of this memorandum is to provide an analysis of biological resources at the La
Rinconada Country Club (Study Area) in Los Gatos, Santa Clara County, California. The report is
intended to support a review of the La Rinconada Country Club Redesign Project (Project) per
the California Environmental Quality Act (CEQA). As part of that review, the memorandum
addresses potential Project affects in accordance with Appendix G of the CEQA guidelines.
Provided herein are descriptions of habitats present, and a discussion of potential environmental
constraints.
2.0 BACKGROUND AND EXISTING CONDITIONS
The La Rinconada Country Club (Study Area) is an approximately 129-acre complex which
includes an 18-hole golf course, tennis courts, private recreation areas, ornamental ponds, pools,
and other buildings and facilities. The Study Area is situated approximately 0.25 miles south of
Highway 85 within an urbanized area in Los Gatos, California with private access driveways to
the east from Clearview Drive and La Rinconada Drive. The Study Area is surrounded on all sides
by residential development. The site has been used for recreation since the late 1920’s and
contains a network of well-maintained paved roads and pathways throughout the site.
3.0 PROJECT DESCRIPTION
The proposed Project will be composed of a redesign of the existing golf course on site. Golf
course modifications will be implemented through scattered earthwork on approximately 37
acres of existing course holes and ornamental ponds (Project Area; Figure 1). Additional Project
components will include upgrades to irrigation systems and concrete pathways, turf lawn
replacement, and removal and replacement of approximately 190 trees within the Project Area.
Following the completion of construction, the proposed land-use will be equivalent to the
existing use as recreation.
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 2
3.1 Project Layout
The Project would incur only slight changes modifications in grade of the existing golf course and
make no major modifications in existing land cover. All existing on-site structures would remain
unchanged but two ornamental ponds will be de-watered and re-graded to slightly different
specifications. Upon project completion, the Country Club will continue to operate one 18-hole
golf course and the membership capacity will remain unchanged. The Project would not expand
or increase the use of any facilities at the Country Club, nor alter ingress and egress routes to
the property. A Project Master Plan including Grading limits are provided in Attachment A..
3.2 Irrigation System and Cart Paths
As part of the proposed Project, the existing irrigation system will be modernized, existing
drainage systems will be upgraded, and the fairway grass will be replaced with hybrid
bermudagrass (Cynodon dactylon); the hybrid bermudagrass will require 35 percent less
irrigation water than the current course grass. In addition to the turf change and drainage
upgrades, the Project would reduce the number of existing golf course cart paths which will
decrease the impervious surface area on the golf course by approximately 70 percent.
3.3 Tree Removal
There are approximately 1,200 trees on the property, most of which are non-native species
planted by the Country Club over the past 50 years. A total of 256 trees will be removed as part
of the Project; most of which are recently planted redwoods (Sequoia sempervirens) and
eucalyptus (Eucalyptus sp.) trees. The Country Club will obtain all necessary permits associated
with the removal of trees including heritage trees as defined by the City of Los Gatos (City) Code
of Ordinances. Removed trees will be replaced at a 1:1 ratio by native oak trees (Quercus sp.)
or other regionally appropriate native tree species. Details for trees to be removed and a
proposed re-planting plan to City compliance are provided in Attachment A.
3.4 Construction
As part of construction activities, grading would be balanced on-site with approximately 60,000
cubic yards of cut and fill. No soil would be imported to or exported from the site. Construction
of the proposed Project is estimated to take approximately seven months to complete and is
scheduled to begin in March of 2026.

4.0 METHODS
This evaluation is based on a review of literature and database sources as well as a site visit
completed by WRA, Inc. (WRA) on January 24, 2025. Prior to the site visit, WRA biologists
reviewed literature resources and performed database searches to assess the potential for
sensitive land cover types (e.g., wetlands) and special-status species (e.g., endangered plants),
including:
x SoilWeb (CSRL 2025)
x Contemporary aerial photographs (Google Earth 2025)
x Historical aerial photographs (NETR 2025)
x National Wetlands Inventory (USFWS 2025a)
x California Natural Diversity Database (CNDDB; CDFW 2025a)
x California Native Plant Society Rare Plant Inventory (CNPS 2025a)
x Consortium of California Herbaria 2 (CCH2 2025)
x USFWS Information Planning and Consultation database (USFWS 2025b)
x eBird Online Database (eBird 2025)
x California Bird Species of Special Concern in California (Shuford and Gardali 2008)
x California Amphibian and Reptile Species of Special Concern (Thomson et al. 2016)
x A Field Guide to Western Reptiles and Amphibians (Stebbins 2003)
x A Manual of California Vegetation, Online Edition (CNPS 2025b)
x California Natural Community List (CDFW 2025)
On January 24, 2025, WRA biologists Daniel Elting and Maya Avendano conducted a field
assessment of the 129-acre Study Area to observe conditions for the presence of sensitive land
cover types and the potential to support habitat for special-status plant and wildlife species.
Potentially jurisdictional areas and sensitive habitats were mapped using a combination of
mapping-grade GPS devices and hand-drawn boundaries on high-resolution aerial imagery.
5.0 RESULTS
5.1 Vegetation Communities and Other Land Cover
WRA observed six land cover types within the Study Area. Non-sensitive land cover types include
developed and ornamental ponds, and potentially sensitive land covers include intermittent
stream, seasonal wetland swale, oak woodland and riparian woodland. Land cover types within
the Study Area are mapped in Figure 1.
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 4
5.1.1 Non-Sensitive Land Cover Types
DEVELOPED
Developed areas comprise the majority of the Study Area
and consist of meticulously maintained fairway lawns and
putting greens, sand bunkers, paved roads and concrete
areas, buildings, swimming pool facilities, and ornamental
landscaping. Mowed lawns are fields of non-native turf
grasses with scattered non-native forbs such as English
plantain (Plantago lanceolata), common sowthistle (Sonchus
oleraceus), with planted stands of coast redwoods, coast live
oaks (Quercus agrifolia), valley oak (Quercus lobata), and
eucalyptus. This land cover type is not considered sensitive
by any regulatory entities.
ORNAMENTAL PONDS
The Study Area contains two manmade ornamental ponds
which were created sometime in the mid 1960’s and
1970’s (NETR 2025). The ponds are managed and filled
with water year-round. The banks of the ponds are
artificially hardscaped with rocks and concrete, with some
areas having a more gradual, vegetated bank. While
minimal, there are some areas on the fringes of the ponds
with sparse, emergent aquatic vegetation encroaching
into the water from the bank. The ponds were created
through excavation of dry land and artificially filled with
diverted water. These water features are unlikely to be
recognized as sensitive by federal or state agencies.
Sensitive Habitats.
5.1.2 Sensitive Habitats
INTERMITTENT STREAM
An intermittent stream flows from south to north in the central
portion of the Study Area into an artificial drain. Intermittent
streams exhibit flow during portions of the year but do not
convey water during the dry season. The stream ordinary high-
water mark (OHWM) was determined by scour, water staining,
debris build up, and changes in vegetation. Flowing water was
present in the stream at the time of the January 24, 2025, site
visit. The stream is surrounded by riparian woodland
vegetation including arroyo willow (Salix lasiolepis) and curly
dock (Rumex crispus). Intermittent stream may be considered
sensitive by the California Department of Fish and Wildlife
(CDFW), Regional Water Quality Control Board (RWQCB), and
the United States Army Corps. of Engineers (Corps.)

www.wra-ca.com · ph: 415.454.8868 5
RIPARIAN WOODLAND
Riparian woodland occurs in the central portion of the Study
Area adjacent to the main office building of the Country Club.
Riparian habitat consists of woody-species-dominated
vegetation that grows because of, or contributes organic
material to, the intermittent stream within the Study Area.
Riparian woodland is primarily dominated by coast live oak,
with ash trees (Fraxinus sp.), elderberry (Sambucus sp.) and
willows (Salix sp.) co-dominant. Poison oak (Toxicodendron
diversilobum)and French broom (Genista monspessulana)
largely dominate the midstory, with sparse herbs growing
through the leaf litter, such as Italian arum (Arum italicum).
Riparian woodland land cover type is considered sensitive by
CDFW. The Project Area will not be within Riparian Woodland
and no affects or disturbance to Riparian Woodland will occur.
SEASONAL WETLAND SWALE
A potential seasonal wetland exists in the central portion
of the Study Area in a heavily modified drainage area
immediately north of the central ornamental pond. The
wetland serves as a drainage basin for coneyance
structures to both the north and south. South of the
wetland an artificial swale drains into the wetland from
the nearby pond. North of the wetland a culvert outlet
drains into the wetland originating from underground
segments of stormwater conveyance beneath roadways.
Some inundation was present in the wetland during the
January 24, 2025 site visit near the northern most culvert.
Vegetation in the seasonal wetland swale was dominated
by wetland plants including cattail (Typha sp.), watercress
(Nasturtium officinale), curly dock (Rumex crispus), and
pale knotweed (Persicaria lapathifolia). Boundaries of the potential seasonal wetland were
mapped based on changes in dominant vegetation and topography but were not formally
assessed for the three wetland parameters used by the Corps. to delineate wetland boundaries.
This seasonal wetland is unlikely to meet the definition of Waters of the U.S. by the Corps. but
may be considered sensitive by CDFW and the RWQCB.

Oak Woodland
The western portion of the Study Area contains a stand of
valley oak woodland surrounding a private park/recreation
area with trails and tennis courts. This habitat primarily
contains valley oak with sparse blue oak (Quercus
douglasii) with minimal understory due to regular mowing
and maintenance of walking trails. Oak woodland and
associated trees may be considered sensitive at state and
local levels.
6.0 SPECIAL-STATUS SPECIES
6.1 Special-status Plant Species
Based upon a review of the resource databases listed in Section 3.0, 76 special-status plant
species have been documented in the vicinity of the Study Area. All special-status plant species
are unlikely or have no potential to occur within the Study Area because suitable conditions are
lacking (e.g., edaphic [soil] conditions, topography, unique pH, associated natural communities,
low levels of disturbance). No special-status plant species were observed within the Study Area
on the January 24, 2025 survey.
6.2 Special-status Wildlife Species
Based upon a review of the resource databases listed in Section 4.0, 40 special-status wildlife
species have been documented in the vicinity of the Study Area. Of these species, most are
excluded based on a lack of habitat features (e.g., tidal marsh, old growth redwood or fir forest,
grassland, sandy beaches or alkaline flats, and the presence of specific host plants). Additional
species are excluded due to the lack of hydrological connection with streams that could support
breeding populations of amphibians, and absence of quality foraging habitat within the Study
Area. As such, most special-status wildlife species documented from the vicinity do not have the
potential to occur within the Study Area.
6.2.1 Species Discussion
Northwestern Pond Turtle (NWPT; Actinemys marmorata) is a federally proposed threatened
reptile that is known to occur within the vicinity of the Study Area. The nearest recorded
occurrence of pond NWPT is in the Vascona Reservoir approximately 0.75 miles southeast of the
Study Area (CNDDB 2024). Within the Study Area, the southeast ornamental pond provides
potential habitat for NWPT due to the presence of minimal aquatic foraging vegetation and
sparse basking sites in the form of above-surface rocks. However, the surrounding urban areas,
heavy human disturbance, and fragmentation of suitable aquatic corridors surrounding the Study
Area make the potential for establishment of pond turtles low. No NWPT were observed on the
January 24, 2025 survey and they were determined to be unlikely to occur in the Study Area.

San Francisco dusky-footed woodrat (SFDFWR;
Neotoma fuscipes annectens)is a regional subspecies of
dusky footed woodrat that is a CDFW Species of Special
Concern. SFDFWR use habitats with dense canopy cover
including oak woodland, chaparral, and riparian
woodlands. Mound shaped dens or “middens” are
constructed by SFDWR using large twigs and
occasionally anthropogenic items such as trash or debris
(Kelly 1990). The nearest recorded occurrence of SFDWR
is approximately 7 miles north of the Study Area along
Saratoga Creek in Cupertino, California. During the site
visit on January 24, 2025, three San Francisco dusky-
footed woodrat nests were observed within riparian
woodland surrounding the intermittent stream in the
northeast portion of the Study Area. The presence of presumed active dens within the Study Area
indicates that SFDFR are present in the Study Area. However they are only present within
Riparian Woodland areas which are to be completed avoided by Project activities.
6.2.2 Protected Nesting Birds and Roosting Bats
species protected by the Migratory Bird Treaty Act (MBTA) as well as by California Fish and
Game Codes (CFGC) have potential to nest in trees, vegetation, or on structures within or
adjacent to the Study Area. No active nests were observed in the January survey as the survey
was outside of the breeding season of most species (Feb – Sep). Additionally, no inactive raptor
nest structures from previous seasons were observed in any of the trees on site. Additionally
special-status bats including CDFW Species of Special Concern (SSC) Townsend’s big-eared bat
(Corynorhinus townsendii,) and pallid bat (Antrozous pallidus) have a potential to roost in
mature trees in the Study Area, although the frequent level of day-time disturbance make this
unlikely.

7.0 ANALYTICAL METHODOLOGY AND SIGNIFICANCE
THRESHOLD CRITERIA
Pursuant to Appendix G, Section IV of the State CEQA Guidelines, a project would have a
significant affect on biological resources if it would:
a) Have a substantial adverse effect, either directly or through habitat modifications, on
any species identified as a candidate, sensitive, or special-status species in local or
regional plans, policies, or regulations, or by the California Department of Fish and
Game or U.S. Fish and Wildlife Service.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations, or by the California
Department of Fish and Game or U.S. Fish and Wildlife Service.
c) Have a substantial adverse effect on federally protected wetlands as defined by
Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool,
coastal, etc.) through direct removal, filling, hydrological interruption, or other means.
d) Interfere substantially with the movement of any native resident or migratory fish or
wildlife species or with established native resident or migratory wildlife corridors, or
impede the use of native wildlife nursery sites.
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan.
These thresholds were utilized in completing the analysis of potential Project affects for CEQA
purposes. For the purposes of this analysis, a “substantial adverse effect” is generally interpreted
to mean that a potential affect could directly or indirectly affect the resiliency or presence of a
local biological community or species population. Potential affects to natural processes that
support biological communities and special-status species populations that can produce similar
effects are also considered potentially significant. Affects to individuals of a species or small
areas of existing biological communities may be considered less than significant if those affects
are speculative, beneficial, de minimis, and/or would not affect the resiliency of a local
population.
8.0 POTENTIAL AFFECTS AND AVOIDANCE MEASURES
The purpose of this assessment is to evaluate the potential affects of Project construction and
operation on existing conditions for biological resources within the Project Area. This section is
structured to specifically address each significance threshold for biological resources from CEQA
Appendix G. Recommendations for avoidance and minimization measures are detailed for affects
that area determined to be potentially significant (Table 1).

8.1 Project Affect and Minimizatino Evaluation for Special-status Species
8.1.1 Special-Status Wildlife
This section analyzes the Project’s potential effects and potential minimization measures for
special-status species in reference to the significance threshold outlined in CEQA Appendix G,
Part IV (a):
a)Does the project have the potential to have a substantial adverse effect, either directly
or through habitat modifications, on any species identified as a candidate, sensitive, or
special-status species in local or regional plans, policies, or regulations, or by the
California Department of Fish and Game or U.S. Fish and Wildlife Service?
Potential for potentially significant effects to special-status species are discussed below.
Potential Affect BIO-1:The southeastern ornamental pond has limited potential to support
northwestern pond turtle, a federal proposed species. While no turtles were
observed on the January 2025 site visit, there are sparse basking sites in the form
of above surface rocks, but corridors for turtles to reach the ponds are virtually
absent.
To reduce potential effects to northwestern pond turtle to a less-than-significant level, the
following measures shall be implemented:
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 11
Avoidance Measure BIO-1: Prior to de-watering or grading of existing ornamental ponds, a
qualified biologist shall conduct a pre-activity survey of the ponds to ensure no
NWPT are present and will be affected. If turtles are discovered, a federally-
approved biologist shall capture and re-locate the turtles to nearby suitable
habitat in consultation with the United States Fish and Wildlife Service (USFWS).
NESTING BIRDS
Special-status and non-status nesting birds protected under the CFGC have the potential to nest
in trees, shrubs, herbaceous vegetation, and on bare ground and man-made structures within
and adjacent to the Project Area Project construction activities have the potential to affect nests
in these areas if construction is initiated during the breeding bird season (typically February 1
through August 31). Potential effects include direct destruction of nests as well as indirect visual
and acoustic disturbance to nesting birds from construction in adjacent areas that have the
potential to result in nest abandonment. Destruction of nests or indirect disturbance from
construction that results in nest abandonment are considered potentially significant affects
under CEQA.
Potential Affect BIO-2: Project construction activities have the potential to directly or indirectly
affect special-status nesting birds and other native nesting birds protected by the
MBTA and CFGC. Construction could directly destroy active nests or cause
disturbance that results in nest abandonment.
To reduce potential for affecting nesting birds to a less-than-significant level, the following
measures shall be implemented:
Avoidance Measure BIO-2:Initiation of construction activities during the avian nesting season
(typically February 1 through August 31) will be avoided to the extent feasible. If
construction initiation during the nesting season cannot be avoided, pre-
construction nesting bird surveys will be conducted within 14 days of initial
ground disturbance or vegetation removal to avoid disturbance to active nests,
eggs, and/or young of nesting birds. Surveys can be used to detect the nests of
special-status as well as non-special-status birds. Surveys will encompass the
entire construction area and the surrounding 500 feet. An exclusion zone where no
construction would be allowed will be established around any active nests of any
protected avian species found in the Project Area until a qualified biologist has
determined that all young have fledged and are independent of the nest.
Suggested exclusion zone distances differ depending on species, location, and
placement of nest, and will be at the discretion of the biologist and, if necessary,
the CDFW. These surveys would remain valid as long as construction activity is
consistently occurring in a given area and will be completed again if there is a
lapse in construction activities of more than 14 consecutive days during the
breeding bird season.
ROOSTING BATS
Special-status and non-status bat species have the potential to be present in redwood or oak
trees throughout the Project Area. Project construction activities have the potential to affect
nests in these areas if construction is initiated during the bat maternity season (generally April
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 12
through October). Potential effects include direct destruction of roosts as well as indirect visual
and acoustic disturbance to roosting bats from construction in adjacent areas. Destruction of
roosts or indirect disturbance from construction that results in roost abandonment are
considered potentially significant effects under CEQA. Based on extensive development within
and adjacent to the Study Area, the area of lost potential roosting habitat is considered a less
than significant effect.
Potential Affect BIO-3: Project construction activities have the potential directly or indirectly
disturb special-status and non-status roosting bats. Construction could directly
destroy active roosts or cause disturbance that results in roost abandonment.
To reduce potential effects of roosting bats to a less-than-significant level, the following
measures shall be implemented:
Avoidance Measure BIO-3: Initiation of construction activities during the bat maternity season
(generally April through October) will be avoided to the extent feasible, any tree
removal or trimming should be conducted outside of the bat maternity season
(generally April through October). If this work window is not feasible, pre-
construction bat roost assessments conducted by a qualified biologist at least 14
days and no more than 30 days prior to removal are recommended to determine
if bats roosts are present that may be affected by Project activities. If special-
status bat species or maternity roosts are detected during these surveys,
additional measures including avoidance of the roost sites until the end of the
maternity roosting season may be recommended.
8.1.2 Sensitive Natural Communities Affects and Avoidance Evaluation
This section addresses the question outlined in CEQA Appendix G, Part IV (b):
b) Does the Project have a substantial adverse effect on any riparian habitat or other
sensitive natural community identified in local or regional plans, policies, regulations, or
by the California Department of Fish and Game or U.S. Fish and Wildlife Service.
While there is sensitive habitat mapped within the Study Area, such as potential seasonal
wetland swale, intermittent stream, oak woodland and riparian woodland, there is no sensitive
habitat within the proposed Project footprint and Project activities will be well isolated from
sensitive areas. The Project will not adversely affect sensitive natural communities.
8.1.3 Affects and Avoidance Evaluation for Wetlands and Other Areas Regulated by Section
404 of the Clean Water Act
This section analyzes the Project’s potential to affect and minimization for wetlands and other
areas presumed or determined to be within the jurisdiction of the Corps. in reference to the
significance threshold outlined in CEQA Appendix G, Part IV (c):
c) Does the Project have the potential to have a substantial adverse effect on state or
federally protected wetlands as defined by Section 404 of the Clean Water Act (including,
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 13
but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling,
hydrological interruption, or other means;
While there is a potential seasonal wetland swale and an intermittent stream within the Study
Area, there are no wetlands and waters within the Project footprint. The Project will not adversely
affect jurisdictional wetlands.
8.1.4 Affects and Minimization Evaluation for Habitat Corridors and Linkages
This section analyzes the Project’s potential to affect and minimization for habitat corridors and
linkages in reference to the significance threshold outlined in CEQA Appendix G, Part IV (d):
d) Does the Project have the potential to interfere substantially with the movement of any
native resident or migratory fish or wildlife species or with established native resident or
migratory wildlife corridors, or impede the use of native wildlife nursery sites;
Movement and migratory corridors are segments of land that provide a link between core habitat
areas (Beier 1992, Soule and Terborgh 1999). The majority of the Study Area is developed or
previously disturbed and is within a densely developed urban area. The site does not contain
sufficient natural features to function as a wildlife movement corridor. The Project will not
adversely effect movement or migratory corridors resulting from the Project because no movement
or migratory corridors are present on the site.
8.1.5 Affects and Minimization Evaluation for Local Policies and Ordinances
This section analyzes the Project’s potential to affect conflicts with local policies and ordinances
in reference to the significance threshold outlined in CEQA Appendix G, Part IV (e):
e) Does the Project have the potential to conflict with any local policies or ordinances
protecting biological resources, such as a tree preservation policy or ordinance;
The Project may affect trees protected by the Town of Los Gatos’s Tree Removal and Pruning
Permit. A tree removal permit will be obtained from the City of Los Gatos prior to the removal of
such trees, in compliance with the City codes.A tree re-planting plan will be implemented as a
condition of the permit to replace all removals at a 1:1 with native oak trees or other regionally
appropriate species. Tree removal and re-planting plans including data on all trees on site are
provided in Attachment A.
The Project will not adversely affect or conflict with local codes and ordinances protecting
biological resources.
8.1.6 Habitat Conservation Plans
This section analyzes the Project’s potential effects and minimization based on conflicts with any
adopted local, regional, and state habitat conservation plans in reference to the significance
threshold outlined in CEQA Appendix G, Part IV (f):
WRA, Inc.| 2169 G East Francisco Blvd., San Rafael, CA 94901
www.wra-ca.com · ph: 415.454.8868 14
f) Does the Project have the potential to conflict with the provisions of an adopted Habitat
Conservation Plan, Natural Community Conservation Plan, or other approved local,
regional, or state habitat conservation plan.
The Study Area is mapped outside of the Habitat Plan Study Area in the Santa Clara County
Habitat Plan. Additionally, the Study Area is surrounded by fully developed residential uses and
would not affect special-status species habitat or other sensitive habitats or involve a change in
use type of the existing land cover. Therefore, the Project would not adversely affect or conflict
with the Santa Clara County Habitat Plan.

Introduction
The purpose of this report is to address the potential construction air quality and health risk impacts
associated with the redesign of the existing La Rinconada Country Club Golf Course located at
14595 Clearview Drive in Los Gatos, California. Air quality impacts would be associated with the
restoration of the golf course and relocation of one of the holes. Air pollutant emissions associated
with construction of the project were estimated using appropriate computer models. In addition,
the potential project health risks and the impact of existing toxic air contaminant (TAC) sources
affecting the nearby sensitive receptors were evaluated. The analysis was conducted following
guidance provided by the Bay Area Air Quality Management District (BAAQMD).1
Project Description
The approximately 87.67-acre project site is the La Rinconada Country Club. The project proposes
restoring seventeen of the eighteen golf holes, modernizing the irrigation and drainage systems,
replace the fairway grass, and replace most of the existing golf course cart paths with reduced
footprint cart paths. The only hole location that would be modified would be the 13th hole, which
would move from the edge of the project site to an internal location on the south side of the project
site. No new or renovated structures are proposed. Construction is proposed to begin in late March
of 2026 and be completed by September 2026.
Setting
The project is located in Santa Clara County, which is in the San Francisco Bay Area Air Basin.
Ambient air quality standards have been established at both the State and federal level. The Bay
Area meets all ambient air quality standards with the exception of ground-level ozone, respirable
particulate matter (PM10), and fine particulate matter (PM2.5).
Air Pollutants of Concern
High ozone concentrations in the air basin are caused by the cumulative emissions of reactive
organic gases (ROG) and nitrogen oxides (NOX). These precursor pollutants react under certain
meteorological conditions to form ozone concentrations. Controlling the emissions of these
precursor pollutants is the focus of the Bay Area’s attempts to reduce ambient ozone
concentrations. The highest ozone concentrations in the Bay Area occur in the eastern and southern
inland valleys that are downwind of air pollutant sources. High ozone concentrations aggravate
respiratory and cardiovascular diseases, reduced lung function, and increase coughing and chest
discomfort.
Particulate matter is another problematic air pollutant in the air basin. Particulate matter is assessed
and measured in terms of respirable particulate matter or particles that have a diameter of 10
micrometers or less (PM10) and fine particulate matter where particles have a diameter of 2.5
micrometers or less (PM2.5). Elevated concentrations of PM10 and PM2.5 are the result of both
region-wide (or cumulative) emissions and localized emissions. High particulate matter

concentrations aggravate respiratory and cardiovascular diseases, reduce lung function, increase
mortality (e.g., lung cancer), and result in reduced lung function growth in children.
Toxic Air Contaminants
TACs are a broad class of compounds known to cause morbidity or mortality, often because they
cause cancer. TACs are found in ambient air, especially in urban areas, and are caused by industry,
agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically
found in low concentrations, even near their source (e.g., diesel particulate matter [DPM] near a
freeway). Because chronic exposure of TACs can result in adverse health effects, they are
regulated at the regional, State, and federal level.
Diesel exhaust is the predominant TAC in urban air and is estimated to represent about three-
quarters of the cancer risk from TACs (based on the Bay Area average). According to the
California Air Resources Board (CARB), diesel exhaust is a complex mixture of gases, vapors,
and fine particles. This complexity makes the evaluation of health effects from diesel exhaust
exposure a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and
formaldehyde, have been previously identified as TACs by the CARB, and are listed as
carcinogens either under the State's Proposition 65 or under the Federal Hazardous Air Pollutants
programs. Health risks from TACs are estimated using the Office of Environmental Health Hazard
Assessment (OEHHA) risk assessment guidelines, which were published in February of 2015 and
incorporated in BAAQMD’s current CEQA guidance.2
PM2.5 emissions can include TACs. Due to the adverse health effects caused by PM2.5 exposure
even at low concentrations, BAAQMD developed assessing methods and health risk thresholds to
address exposure to increased concentrations caused by project PM2.5 emissions.3
Sensitive Receptors
There are groups of people more affected by air pollution than others. CARB has identified the
following persons who are most likely to be affected by air pollution: children under 16, the elderly
over 65, athletes, and people with cardiovascular and chronic respiratory diseases. These groups
are classified as sensitive receptors. Locations that may contain a high concentration of these
sensitive population groups include residential areas, hospitals, daycare facilities, elder care
facilities, and elementary schools. For cancer risk assessments, infants and small children are the
most sensitive receptors, since they are more susceptible to cancer causing TACs. Residential
locations are assumed to include infants and small children. The closest sensitive receptors to the
project site would be located in the adjacent single-family residences surrounding the golf course.
Roxbury Elderly Care is located to the west of the project site. There are additional single-family
residences surrounding the site at further distances. This project would not introduce new sensitive
receptors (i.e., residents) to the area.

Bay Area Air Quality Management District (BAAQMD)
BAAQMD has jurisdiction over an approximately 5,600-square mile area, commonly referred to
as the San Francisco Bay Area (Bay Area). The District’s boundary encompasses the nine San
Francisco Bay Area counties, including Alameda County, Contra Costa County, Marin County,
San Francisco County, San Mateo County, Santa Clara County, Napa County, southwestern
Solano County, and southern Sonoma County.
BAAQMD is the lead agency in developing plans to address attainment and maintenance of the
National Ambient Air Quality Standards and California Ambient Air Quality Standards. The
District also has permit authority over most types of stationary equipment utilized for the proposed
project. The BAAQMD is responsible for permitting and inspection of stationary sources;
enforcement of regulations, including setting fees, levying fines, and enforcement actions; and
ensuring that public nuisances are minimized.
BAAQMD’s Community Air Risk Evaluation (CARE) program was initiated in 2004 to evaluate
and reduce health risks associated with exposures to outdoor TACs in the Bay Area.4 The program
examines TAC emissions from point sources, area sources, and on-road and off-road mobile
sources with an emphasis on diesel exhaust, which is a major contributor to airborne health risk in
California. The CARE program is an on-going program that encourages community involvement
and input. The technical analysis portion of the CARE program has been implemented in three
phases that includes an assessment of the sources of TAC emissions, modeling and measurement
programs to estimate concentrations of TAC, and an assessment of exposures and health risks.
Throughout the program, information derived from the technical analyses has been used to develop
emission reduction activities in areas with high TAC exposures and high density of sensitive
populations. Risk reduction activities associated with the CARE program are focused on the most
at-risk communities in the Bay Area. Seven areas have been identified by BAAQMD as impacted
communities. They include Eastern San Francisco, Richmond/San Pablo, Western Alameda, San
José, Vallejo, Concord, and Pittsburgh/Antioch. The project site is not located within any of the
BAAQMD CARE areas.
Overburdened communities are areas located (i) within a census tract identified by the California
Communities Environmental Health Screening Tool (CalEnviroScreen), Version 4.0 implemented
by OEHHA, as having an overall score at or above the 70th percentile, or (ii) within 1,000 feet of
any such census tract.5 The BAAQMD has identified several overburdened areas within its
boundaries. However, the project site is not within an overburdened area as the Project site is
scored at the 15th percentile on CalEnviroScreen.6

BAAQMD CEQA Air Quality Guidelines
In June 2010, BAAQMD adopted thresholds of significance to assist in the review of projects
under CEQA. In 2023, the BAAQMD revised the California Environmental Quality Act (CEQA)
Air Quality Guidelines that include significance thresholds to assist in the evaluation of air quality
impacts of projects and plans proposed within the Bay Area. The current BAAQMD guidelines
provide recommended procedures for evaluating potential air impacts during the environmental
review process consistent with CEQA requirements including thresholds of significance,
mitigation measures, and background air quality information. They include assessment
methodologies for criteria air pollutants, air toxics, odors, and GHG emissions as shown in Table
1.7 Air quality impacts and health risks are considered potentially significant if they exceed these
thresholds.
The BAAQMD recommends all projects include a “basic” set of best management practices
(BMPs) to manage fugitive dust and consider impacts from dust (i.e., fugitive PM10 and PM2.5) to
be less than significant if BMPs are implemented (listed below). BAAQMD strongly encourages
enhanced BMPs for construction sites near schools, residential areas, other sensitive land uses, or
if air quality impacts were found to be significant.

Los Gatos 2040 General Plan
The Los Gatos 2040 General Plan was adopted by the Los Gatos Town Council on June 30, 2022.
The following air quality policies are applicable to the project:
Policy ENV-8.1 Air Quality Standards. Federal, State, and regional air quality goals,
policies, standards, and requirements shall be addressed during
environmental review for local land use and development decisions.
Applicable standards or requirements, if not already in the proposed plans,
shall be incorporated as conditions of approval.
Policy ENV-8.7 Reduce Effects of High Air Pollutant Concentrations. Require
developments to incorporate site planning techniques that reduce exposure
of people to the impacts of high air pollutants from adjacent roadways.
Policy ENV-8.9 Air Pollution Impacts During Construction. Require project proponents
to prepare and implement a construction management plan that incorporates
Best Available Control Measures and all best management practices in
accordance with the Air District standards to reduce criteria pollutants.
Construction Period Emissions
The California Emissions Estimator Model (CalEEMod) Version 2022 was used to estimate
emissions from on-site construction activity, construction vehicle trips, and evaporative emissions.
The project land use types and size were input to CalEEMod. The CalEEMod model output along
with construction inputs are included in Attachment 1.
CalEEMod Inputs
Land Uses
The proposed project land uses were entered into CalEEMod as described in Table 2.
Table 2. Summary of Project Land Use Inputs
Project Land Uses Size Units Square Feet (sf) Acreage
Golf Course 87.67 Acre - 87.67
Construction Inputs
CalEEMod computes annual emissions for construction that are based on the project type, size,
and acreage. The model provides emission estimates for both on-site and off-site construction
activities. On-site activities are primarily made up of construction equipment emissions, while off-
site activity includes worker, hauling, and vendor traffic. The construction build-out scenario,
including equipment quantities, average hours per day, total number of workdays, and schedule,
were based on information provided by the project applicant (included in Attachment 1). The
project applicant estimates the earliest possible start date to be March 2026, and the project would
be built out over a period of approximately 7 months, or 161 construction workdays.
Construction Traffic Emissions
Construction would produce traffic in the form of worker trips and truck traffic. The traffic-related
emissions are based on worker and vendor trip estimates produced by CalEEMod and haul trips
that were computed based on the amount of asphalt truck trips to and from the site. CalEEMod
provides daily estimates of worker and vendor trips for each applicable phase. The amount of
asphalt was provided and converted to daily one-way trips, assuming two trips per delivery. There
is no planned export or import of soil material as the cut and grade will be balanced.
Summary of Computed Construction Period Emissions
Average daily construction emissions were estimated for the total duration of the project (161
days). Table 3 shows the average daily construction emissions of ROG, NOX, PM10 exhaust, and
PM2.5 exhaust during construction of the project. As indicated in Table 3, the predicted project
unmitigated construction emissions would not exceed the BAAQMD significance thresholds
during any year of construction.

Construction activities, particularly during site preparation and grading, would temporarily
generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include
disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly
controlled, vehicles leaving the site would deposit mud on local streets, which could be an
additional source of airborne dust after it dries. The BAAQMD recommends all projects include a
“basic” set of best management practices (BMPs) to manage fugitive dust and consider impacts
from dust (i.e. fugitive PM10 and PM2.5) to be less than significant BMPs are implemented. The
project would be required to implement the BMPs recommended by BAAQMD during all phases
of construction to reduce dust and other particulate matter emissions, per the Town’s General Plan
policy ENV-8.9.
General Plan Policy ENV-8.9: Include BAAQMD basic BMPs to control dust and
exhaust during construction.
During any construction period ground disturbance, the applicant shall ensure that the project
contractor implement measures to control dust and exhaust. Implementation of the measures
recommended by BAAQMD and listed below would reduce the air quality impacts associated with
grading and new construction to a less-than-significant level.
1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and
unpaved access roads) shall be watered two times per day.
2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
3. All visible mud/dirt track-out onto adjacent public roads shall be removed using wet power
vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
4. All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).
5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as
practicable. Building pads shall be laid as soon as practicable after grading unless seeding
or soil binders are used.
6. All excavation, grading, and/or demolition activities shall be suspended when average wind
speeds exceed 20 mph.
7. All trucks and equipment, including their tires, shall be washed off prior to leaving the site.
8. Unpaved roads providing access to site located 100 feet of further from a paved road shall
be treated with a 6- to 12-inch layer of compacted layer of wood chips, mulch, or gravel.
9. Publicly visible signs shall be posted with the telephone number and name of the person to
contact at the lead agency regarding dust complaints. This person shall respond and take
corrective action within 48 hours. The Air District’s General Air Pollution Complaints
number shall be visible to ensure compliance with applicable regulations.
The Town’s General Plan Policy ENV-8.9 is consistent with BAAQMD-recommended basic
BMPs for reducing fugitive dust contained in the BAAQMD CEQA Air Quality Guidelines. For
this analysis, only the basic set of BMPs are required as the Project emissions and PM2.5 impacts
were below the BAAQMD thresholds. Enhanced BMPs would be required as mitigation if air
quality impacts were found to be significant.
Construction Health Risk Impacts
Health risk impacts were addressed by predicting increased lifetime cancer risk, the increase in
annual PM2.5 concentrations, and computing the Hazard Index (HI) for non-cancer health risks.
Construction activity is the only source of TAC emissions from the Project that would have health
risk impacts. Construction equipment and associated heavy-duty truck traffic generates diesel
exhaust, which is a known TAC. These exhaust emissions pose health risks for sensitive receptors
such as surrounding residents. The primary health risk impact issues associated with construction
emissions are cancer risk and exposure to PM2.5. A health risk assessment of the project
construction activities was conducted that evaluated potential health effects to nearby sensitive
receptors from construction emissions of DPM and PM2.5.8 This assessment included dispersion
modeling to predict the off-site concentrations resulting from project construction, so that lifetime
cancer risks and non-cancer health effects could be evaluated.
Modeled Sensitive Receptors
Receptors for this assessment included locations where sensitive populations would be present for
extended periods of time (i.e., chronic exposures). This includes the existing residences
surrounding the site and Roxbury Elderly Care as shown in Figure 1. Residential receptors are
assumed to include all receptor groups (i.e., third trimester, infants, children, and adults) with
almost continuous exposure to project emissions. Roxbury Elderly Care is assumed to be adults
only with almost continuous exposure to project emissions. While there are additional receptors
within 1,000 feet of the project site, the receptors chosen are adequate to identify maximum
impacts from the project.
Construction Emissions
The CalEEMod model provided total uncontrolled annual PM10 exhaust emissions (assumed to be
DPM) for the off-road construction equipment and for exhaust emissions from on-road vehicles.
Total DPM emissions were estimated to be 0.04 tons (81 pounds). Fugitive dust emissions (PM2.5),
which reflect the application of BMPs, are less than 0.01 tons (1 pound) from all construction
stages. The on-road emissions are a result of haul truck travel during grading activities, worker
travel, and vendor deliveries during construction. A trip length of one mile was used to represent
vehicle travel while at or near the construction site. It was assumed that the emissions from on-
road vehicles traveling at or near the site would occur at the construction site.
Dispersion Modeling
The U.S. EPA AERMOD dispersion model was used to predict DPM and PM2.5 concentrations at
sensitive receptors (i.e., residences) in the vicinity of the project construction area. The AERMOD
dispersion model is a BAAQMD-recommended model for use in modeling analysis of these types
of emission activities for CEQA projects.9 Emission sources for the construction site were grouped
into two categories: exhaust emissions of DPM and fugitive PM2.5 dust emissions.
8 DPM is identified by California as a toxic air contaminant due to the potential to cause cancer.
9 BAAQMD, 2023, Appendix E of the 2022 BAAQMD CEQA Guidelines. April.
Construction Sources
To represent the construction equipment exhaust emissions, an area source was used with an
emission release height of 20 feet (6 meters).10 The release height incorporates both the physical
release height from the construction equipment (i.e., the height of the exhaust pipe) and plume rise
after it leaves the exhaust pipe. Plume rise is due to both the high temperature of the exhaust and
the high velocity of the exhaust gas. It should be noted that when modeling an area source, plume
rise is not calculated by the AERMOD dispersion model as it would do for a point source (exhaust
stack). Therefore, the release height from an area source used to represent emissions from sources
with plume rise, such as construction equipment, was based on the height the exhaust plume is
expected to achieve, not just the height of the top of the exhaust pipe.
For modeling fugitive PM2.5 emissions, an area source with a near-ground level release height of
7 feet (2 meters) was used. Fugitive dust emissions at construction sites come from a variety of
sources, including truck and equipment travel, grading activities, truck loading (with loaders) and
unloading (rear or bottom dumping), loaders and excavators moving and transferring soil and other
materials, etc. All of these activities result in fugitive dust emissions at various heights at the
point(s) of generation. Once generated, the dust plume will tend to rise as it moves downwind
across the site and exit the site at a higher elevation than when it was generated. For all these
reasons, a 7-foot release height was used as the average release height across the construction site.
Emissions from the construction equipment and on-road vehicle travel were distributed throughout
the modeled area sources.
AERMOD Inputs and Meteorological Data
The modeling used a five-year meteorological data set (2013-2017) from the San José Airport
prepared for use with the AERMOD model by the BAAQMD. Construction emissions were
modeled as occurring Monday through Friday between 7:00 a.m. to 5:30 p.m. and on Saturdays
between 9:00 a.m. to 5:30 p.m., when the majority of construction is expected to occur according to
the project applicant. Annual DPM and PM2.5 concentrations from construction activities during
the 2026 period were calculated at nearby sensitive receptors using the model. Receptor heights
of 5 feet (1.5 meters) were used to represent the breathing height on the first floor of nearby
residences and at Roxbury Elderly Care.11
Summary of Construction Health Risk Impacts
The maximum increased cancer risks were calculated using the modeled TAC concentrations
combined with BAAQMD CEQA guidance for age sensitivity factors and exposure parameters.
Age-sensitivity factors reflect the greater sensitivity of infants and small children to cancer causing
TACs. Third trimester, infant, child, and adult exposures were assumed to occur at all residences

during the entire construction period, while adult exposures were assumed at Roxbury Elderly
Care.
Non-cancer health hazards and maximum PM2.5 concentrations were also calculated. The
maximum modeled annual PM2.5 concentration was calculated based on combined exhaust and
fugitive concentrations. The maximum computed HI value was based on the ratio of the maximum
DPM concentration modeled and the chronic inhalation DPM reference exposure level of 5 μg/m3.
The modeled maximum annual DPM and PM2.5 concentrations were identified at nearby sensitive
receptors to find the MEI. Results of this assessment indicated that the construction MEI was
located on the first floor (5 feet above the ground) of a single-family residence east of the project
site. The location of the MEI and nearby sensitive receptors are shown in Figure 1. Table 4
summarizes the maximum cancer risks, PM2.5 concentrations, and health hazard indexes for project
related construction activities. Attachment 2 to this report includes the emission calculations used
for construction modeling and the cancer risk calculations.
As shown in Table 4, the project’s uncontrolled construction maximum cancer risk, annual PM2.5
concentration, and HI do not exceed their respective BAAQMD single-source significance
threshold.
Additionally, modeling was conducted to predict the cancer risks, non-cancer health hazards, and
maximum PM2.5 concentrations associated with construction activities at the nearby Roxbury

The cancer risk, PM2.5 concentration, and HI did not exceed their respective BAAQMD single-
source significance thresholds, as shown in Table 4.

Figure 1. Location of Project Construction Site, Off-Site Sensitive Receptors, and
Maximum TAC Impact (MEI)
Cumulative Health Risk Impacts
Cumulative health risk assessments look at all substantial sources of TACs located within 1,000
feet of a project site (i.e., influence area) that can affect sensitive receptors. These sources include
rail lines, highways, busy surface streets, and stationary sources identified by BAAQMD.
A review of the project area using BAAQMD’s geographic information systems (GIS) screening
maps identified the existing health risks from nearby roadway and stationary sources at the MEI.
Local roadways and five stationary sources within the 1,000-foot influence area could have
cumulative health risk impacts at the MEI. Figure 2 shows the locations of the sources affecting
the MEIs within the influence area. Health risk impacts from these sources upon the MEI are
reported in Table 5. Details of the cumulative screening and health risk calculations are included
in Attachment 3.
Figure 2. Project Site and Nearby TAC and PM2.5 Sources
Nearby Local Roadways
The project site is located near multiple intersecting streets. Cancer risk, PM2.5 concentrations, and
HI associated with traffic on the nearby roadways were estimated using BAAQMD screening
values provided via GIS data files (i.e., raster files).12 BAAQMD raster files provide screening-
level cancer risk, PM2.5 concentrations, and HI for roadways within the Bay Area and were
produced using AERMOD and 20x20-meter emissions grid. The raster file uses EMFAC2021 data
for vehicle emissions and fleet mix for roadways and includes Appendix E of the Air District’s
CEQA Air Quality Guidance for risk assessment assumptions. These estimates represent
conservative risks reflective of 2022 conditions and are meant to provide a conservative estimate
of future conditions, which do not reflect the increased proportion of zero emission motor vehicles
that will result in lower future emissions.13 These screening values are considered higher than
values that would be obtained with refined modeling methods. These raster data are based on
region-wide emissions rather than just those that occur within 1,000 feet of the project. More
information regarding the assumptions used to develop the screening layers can be found in
Sections 6 and 7 in Appendix E of BAAQMD’s 2022 CEQA guidance.14 Screening-level cancer

risk, PM2.5 concentration, and HI for the cumulative roadway impacts at the construction MEI are
listed in Table 5.
BAAQMD Permitted Stationary Sources
Permitted stationary sources of air pollution near the project site were identified using BAAQMD’s
Permitted Stationary Sources 2022 GIS website,15 which identifies the location of nearby
stationary sources and their estimated risk and hazard impacts, including emissions and
adjustments to account for OEHHA guidance. Five sources were identified using this tool, two gas
dispensing facilities (GDF), and three emergency diesel generators. While these sources are within
1,000 feet from the edge of the project site, the closest source to the MEI is approximately 1,500
feet away with others over 3,000 feet away. Risks from these existing stationary sources would be
negligible as the distance between source and MEI is too great for any meaningful TAC
concentration to affect the MEI. Building downwash, wind interaction with terrain, and other
environmental factors would assist in diluting any airborne TAC concentration. As a result, risks
from existing stationary sources upon the MEI are considered negligible and are not included in
this analysis.
Summary of Cumulative Health Risk Impact at Construction MEIs
Table 5 reports both the project and cumulative health risk impacts at the sensitive receptor most
affected by construction (i.e., the MEI). As shown in Table 5, the project does not exceed any
BAAQMD single-source or cumulative source threshold.

25-007 La Rinconada Country Club, Los Gatos BMPs T4F Detailed Report, 1/28/202548 / 54Temperature and Extreme Heat 12.6 annual days of extreme heatExtreme Precipitation 5.85 annual days with precipitation above 20 mmSea Level Rise — meters of inundation depthWildfire 0.00 annual hectares burnedTemperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures fromobserved historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall ifreceived over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radkeet al., 2017, CEC-500-2017-008), andconsider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled withextreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: Norise, 0.5 meter, 1.0 meter, 1.41 metersWildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical dataof climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. Thefour simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5),Average conditions (CanESM2), Range ofdifferent rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.6.2.

INTRODUCTION
This report addresses the potential for temporary noise or vibration impacts resulting from the La
Rinconada Country Club Golf Course Modernization Project at 14595 Clearview Drive in Los
Gatos, California. The report presents the project description and background information on
environmental noise and vibration, the applicable regulatory criteria used in the assessment, and
the evaluation of construction-related noise and vibration impacts.
PROJECT DESCRIPTION
Proposed Layout
The proposed project would leave 17 of the 18 holes in their current locations. The only hole
location that would be modified would be the 13th hole, which would move from the edge of the
project site to an internal location on the south side of the project site. All existing on-site structures
would remain unchanged. Upon project completion, the Country Club would continue to operate
one 18-hole golf course on the property, and the membership numbers would remain unchanged.
The proposed project would not expand or increase the use of any facilities at La Rinconada
Country Club. The proposed project would not alter ingress and egress to the property.
Irrigation System and Cart Paths
As part of the proposed project, the irrigation system would be modernized; on-site drainage
systems would be upgraded; and the fairway grass would be replaced with a modern hybrid
bermudagrass that requires 35 percent less irrigation water than the current course grass. In
addition to the turf change and drainage upgrades, the proposed project would replace most of the
existing golf course cart paths with reduced footprint cart paths. Replacement of the cart paths
would reduce impervious surfaces on the golf course by approximately 70 percent.
Tree Removal
There are approximately 1,200 trees on the property, most of which are non-native species planted
by the Club over the past 50 years. Recently introduced redwoods and eucalyptus trees would be
replaced by native oaks as a part of the proposed project. The plan would remove approximately
240 trees, most of which are redwoods and eucalyptus. The proposed project would replace the
trees removed at a one-to-one ratio, planting approximately 240 native oak trees on the golf course.
This would restore the property to a more natural state similar to the late 1920’s.
Construction
As part of construction activities, grading would be balanced on-site with approximately 52,780
cubic yards of cut and fill. No soil would be imported to or exported from the site. Construction
of the proposed project is estimated to take approximately seven months to complete and is
scheduled to begin in late March of 2026.

SETTING
Fundamentals of Environmental Noise
Noise may be defined as unwanted sound. Noise is usually objectionable because it is disturbing
or annoying. The objectionable nature of sound could be caused by its pitch or its loudness. Pitch
is the height or depth of a tone or sound, depending on the relative rapidity (frequency) of the
vibrations by which it is produced. Higher pitched signals sound louder to humans than sounds
with a lower pitch. Loudness is intensity of sound waves combined with the reception
characteristics of the ear. Intensity may be compared with the height of an ocean wave in that it is
a measure of the amplitude of the sound wave.
In addition to the concepts of pitch and loudness, there are several noise measurement scales which
are used to describe noise in a particular location. A decibel (dB) is a unit of measurement which
indicates the relative amplitude of a sound. The zero on the decibel scale is based on the lowest
sound level that the healthy, unimpaired human ear can detect. Sound levels in decibels are
calculated on a logarithmic basis. An increase of 10 decibels represents a ten-fold increase in
acoustic energy, while 20 decibels is 100 times more intense, 30 decibels is 1,000 times more
intense, etc. There is a relationship between the subjective noisiness or loudness of a sound and its
intensity. Each 10 decibel increase in sound level is perceived as approximately a doubling of
loudness over a fairly wide range of intensities. Technical terms are defined in Table 1.
There are several methods of characterizing sound. The most common in California is the A-
weighted sound level (dBA). This scale gives greater weight to the frequencies of sound to which
the human ear is most sensitive. Representative outdoor and indoor noise levels in units of dBA
are shown in Table 2. Because sound levels can vary markedly over a short period of time, a
method for describing either the average character of the sound or the statistical behavior of the
variations must be utilized. Most commonly, environmental sounds are described in terms of an
average level that has the same acoustical energy as the summation of all the time-varying events.
This energy-equivalent sound/noise descriptor is called Leq. The most common averaging period
is hourly, but Leq can describe any series of noise events of arbitrary duration.
The scientific instrument used to measure noise is the sound level meter. Sound level meters can
accurately measure environmental noise levels to within plus or minus 1 dBA. Various computer
models are used to predict environmental noise levels from sources, such as roadways and airports.
The accuracy of the predicted models depends upon the distance the receptor is from the noise
source. Close to the noise source, the models are accurate to within about plus or minus 1 to 2
dBA.

TABLE 1 Definition of Acoustical Terms Used in this Report
Term Definition
Decibel, dB A unit describing the amplitude of sound, equal to 20 times the logarithm
to the base 10 of the ratio of the pressure of the sound measured to the
reference pressure. The reference pressure for air is 20 micro Pascals.
Sound Pressure Level Sound pressure is the sound force per unit area, usually expressed in micro
Pascals (or 20 micro Newtons per square meter), where 1 Pascal is the
pressure resulting from a force of 1 Newton exerted over an area of 1 square
meter. The sound pressure level is expressed in decibels as 20 times the
logarithm to the base 10 of the ratio between the pressures exerted by the
sound to a reference sound pressure (e. g., 20 micro Pascals). Sound
pressure level is the quantity that is directly measured by a sound level
meter.
Frequency, Hz The number of complete pressure fluctuations per second above and below
atmospheric pressure. Normal human hearing is between 20 Hz and 20,000
Hz. Infrasonic sound are below 20 Hz and Ultrasonic sounds are above
20,000 Hz.
A-Weighted Sound
Level, dBA
The sound pressure level in decibels as measured on a sound level meter
using the A-weighting filter network. The A-weighting filter de-emphasizes
the very low and very high frequency components of the sound in a manner
similar to the frequency response of the human ear and correlates well with
subjective reactions to noise.
Equivalent Noise Level,
Leq
The average A-weighted noise level during the measurement period.
Lmax, Lmin The maximum and minimum A-weighted noise level during the
measurement period.
L01, L10, L50, L90 The A-weighted noise levels that are exceeded 1%, 10%, 50%, and 90% of
the time during the measurement period.
Day/Night Noise Level,
Ldn or DNL
The average A-weighted noise level during a 24-hour day, obtained after
addition of 10 decibels to levels measured in the night between 10:00 pm and
7:00 am.
Community Noise
Equivalent Level,
CNEL
The average A-weighted noise level during a 24-hour day, obtained after
addition of 5 decibels in the evening from 7:00 pm to 10:00 pm and after
addition of 10 decibels to sound levels measured in the night between 10:00
pm and 7:00 am.
Ambient Noise Level The composite of noise from all sources near and far. The normal or existing
level of environmental noise at a given location.
Intrusive That noise which intrudes over and above the existing ambient noise at a
given location. The relative intrusiveness of a sound depends upon its
amplitude, duration, frequency, and time of occurrence and tonal or
informational content as well as the prevailing ambient noise level.

Fundamentals of Groundborne Vibration
Ground vibration consists of rapidly fluctuating motions or waves with an average motion of zero.
Several different methods are typically used to quantify vibration amplitude. One method is the
Peak Particle Velocity (PPV). The PPV is defined as the maximum instantaneous positive or
negative peak of the vibration wave. In this report, a PPV descriptor with units of mm/sec or in/sec
is used to evaluate construction generated vibration for building damage and human complaints.
Table 3 displays the reactions of people and the effects on buildings that continuous or frequent
intermittent vibration levels produce. The guidelines in Table 3 represent syntheses of vibration
criteria for human response and potential damage to buildings resulting from construction
vibration.
Construction activities can cause vibration that varies in intensity depending on several factors.
The use of pile driving and vibratory compaction equipment typically generates the highest
construction related groundborne vibration levels. Because of the impulsive nature of such
activities, the use of the PPV descriptor has been routinely used to measure and assess groundborne
vibration and almost exclusively to assess the potential of vibration to cause damage and the degree
of annoyance for humans.
The two primary concerns with construction-induced vibration, the potential to damage a structure
and the potential to interfere with the enjoyment of life, are evaluated against different vibration
limits. Human perception to vibration varies with the individual and is a function of physical
setting and the type of vibration. Persons exposed to elevated ambient vibration levels, such as
people in an urban environment, may tolerate a higher vibration level.
Structural damage can be classified as cosmetic only, such as paint flaking or minimal extension
of cracks in building surfaces; minor, including limited surface cracking; or major, that may
threaten the structural integrity of the building. Safe vibration limits that can be applied to assess
the potential for damaging a structure vary by researcher. The damage criteria presented in Table
3 include several categories for ancient, fragile, and historic structures, the types of structures most
at risk to damage. Most buildings are included within the categories ranging from “Historic and
some old buildings” to “Modern industrial/commercial buildings”. Construction-induced vibration
that can be detrimental to the building is very rare and has only been observed in instances where
the structure is at a high state of disrepair and the construction activity occurs immediately adjacent
to the structure.
The annoyance levels shown in Table 3 should be interpreted with care since vibration may be
found to be annoying at lower levels than those shown, depending on the level of activity or the
sensitivity of the individual. To sensitive individuals, vibrations approaching the threshold of
perception can be annoying. Low-level vibrations frequently cause irritating secondary vibration,
such as a slight rattling of windows, doors, or stacked dishes. The rattling sound can give rise to
exaggerated vibration complaints, even though there is very little risk of actual structural damage.

Regulatory Background - Noise
The State of California Environmental Quality Act (CEQA) Guidelines, Appendix G, are used to
assess the potential significance of impacts pursuant to local General Plan policies, Municipal
Code standards, or the applicable standards of other agencies. A summary of the applicable
regulatory criteria is provided below.
State of California
State CEQA Guidelines. CEQA contains guidelines to evaluate the significance of effects of
environmental noise attributable to a proposed project. Under CEQA, construction noise or
vibration impacts would be considered significant if the project would result in:
(a) Generation of a substantial temporary or permanent increase in ambient noise levels in the
vicinity of the project in excess of standards established in the local General Plan or Noise
Ordinance, or applicable standards of other agencies;
(b) Generation of excessive groundborne vibration or groundborne noise levels; or

Town of Los Gatos
Town of Los Gatos 2040 General Plan. The Town of Los Gatos identifies the following policies
applicable to the proposed development:
ENV 21 - Ensure that construction and maintenance equipment noise does not adversely affect
land uses.
ENV 21.1 Noise Attenuation, Town Equipment
All Town-owned and operated construction and maintenance equipment, and
equipment for these activities operated under contract with the Town, shall contain
state-of-the-art noise attenuation equipment.
ENV 21.2 Noise Attenuation, Private Equipment
Monitor and modify Town ordinances, as appropriate, to control nuisance noise
from maintenance equipment used in the community.
Town of Los Gatos Code of Ordinances The Town Noise Ordinance (Chapter 16 of the Town
Municipal Code) specifies noise limits to protect the peace, health, and safety of its citizens from
such noise and vibration. The following policies would be applicable to the project.
Sec. 16.20.035. - Construction
(a) Notwithstanding any other provision of this chapter, between the hours of 8:00 a.m. to
6:00 p.m. weekdays, and 9:00 a.m. to 4:00 p.m. Saturdays, construction, alteration or repair
activities which are authorized by a valid Town permit or as otherwise allowed by Town
permit, shall be allowed if they meet at least one of the following noise limitations:
(1) No individual piece of equipment shall produce a noise level exceeding eighty-
five (85) dBA at twenty-five (25) feet. If the device is located within a structure on
the property, the measurement shall be made at distances as close to twenty-five
(25) feet from the device as possible.
(2) The noise level at any point outside of the property plane shall not exceed
eighty-five (85) dBA.
Regulatory Background – Vibration
California Department of Transportation. The California Department of Transportation
recommends a vibration limit of 0.5 in/sec PPV for buildings structurally sound and designed to
modern engineering standards, which typically consist of buildings constructed since the 1990s.
Conservative vibration limits of 0.3 in/sec PPV is used for buildings that are found to be
structurally sound but where structural damage is a major concern (see Table 3 above for further
explanation). For historical buildings or some older buildings, a vibration limit of 0.25 in/sec PPV
would apply.

NOISE IMPACTS AND AVOIDANCE MEASURES
Significance Criteria
The following criteria were used to evaluate the significance of noise and vibration resulting from
the project:
(a) Generation of a substantial temporary or permanent increase in ambient noise levels
in the vicinity of the project in excess of standards established in the local general
plan or noise ordinance, or applicable standards of other agencies;
(b) Generation of excessive groundborne vibration or groundborne noise levels;
Impact 1: Temporary Construction Noise. Existing receptors may temporarily be exposed
to construction noise levels exceeding the Town of Los Gatos construction noise
thresholds, but the short-term noise would result in a less-than-significant impact.
For construction noise, the potential for noise impacts was assessed by considering several factors,
including the proximity of Project-related noise sources to noise-sensitive land uses (i.e., “sensitive
receptors”), typical noise levels associated with construction equipment, the potential for
construction noise levels to interfere with daytime activities, the duration that sensitive receptors
would be affected, and whether proposed activities would occur outside the construction time
limits or noise limits established in the local ordinance. For purposes of this analysis, temporary
exposure to noise during the daytime is generally not considered significant if it is for short
durations even if the noise is above the thresholds discussed herein, which is based on the
reasonable assumption that most people would expect and accept short-term noise associated with
a nearby construction project.
Construction of the proposed project is estimated to take approximately seven months to complete
and is scheduled to begin in late March of 2026. Construction would progress sequentially from
hole to hole; so, only portions of the property will experience construction activity at any single
point in time during the construction period. In general, the modernization activity would last
approximately two to four weeks per hole, depending on hole location. Proposed hours of
construction are 7:00 a.m. to 5:30 p.m. on weekdays and 9:00 a.m. to 5:30 p.m. on Saturdays. No
construction would occur on Sundays or holidays.
Construction phases would include site preparation, grading/excavation, trenching/foundation, and
paving. During each phase of construction, there would be a different mix of equipment operating,
and noise levels would vary by phase and vary within phases, based on the amount of equipment
in operation and the location at which the equipment is operating.
Noise impacts resulting from construction depend upon the noise generated by various pieces of
construction equipment, the timing and duration of noise-generating activities, and the distance
between construction noise sources and noise-sensitive areas. Construction noise impacts
primarily result when construction activities occur during noise-sensitive times of the day (e.g.,
9
early morning, evening, or nighttime hours), the construction occurs in areas immediately
adjoining noise-sensitive land uses, or when construction lasts over extended periods of time.
The Town’s Code of Ordinances Section 16.20.035 limits construction activities to the hours of
8:00 a.m. to 6:00 p.m. on weekdays and between the hours of 9:00 a.m. and 4:00 p.m. on Saturdays.
No construction is permitted on Sundays or holidays. Section 16.20.035 also states that at least
one of the following conditions should be met; (1) construction noise limits of 85 dBA at a distance
of 25 feet for any single piece of equipment and (2) noise level at any point outside of the property
plane of the project site is limited to 85 dBA.
Construction activities generate considerable amounts of noise, especially during earth-moving
activities when heavy equipment is used. The hauling of excavated materials and construction
materials would generate truck trips on local roadways, as well. For the proposed development,
pile driving is not anticipated. The typical range of maximum instantaneous noise levels for the
proposed project would be 70 to 90 dBA Lmax at a distance of 50 feet (see Table 4) from the
equipment.
Table 5 shows the hourly average noise level ranges, by construction phase, typical for various
types of projects. Hourly average noise levels generated by construction are about 71 to 89 dBA
Leq for recreation projects, measured at a distance of 50 feet from the center of a busy construction
site. Construction-generated noise levels drop off at a rate of about 6 dBA per doubling of the
distance between the source and receptor. Shielding by buildings or terrain often results in lower
construction noise levels at distant receptors.
Equipment expected to be used in each construction stage are summarized in Table 6, along with
the quantity of each type of equipment and the reference noise level at 25 feet, assuming the
operation of the two loudest pieces of construction equipment for each construction phase.
Federal Highway Administration’s (FHWA’s) Roadway Construction Noise Model (RCNM) was
used to calculate the hourly average noise levels for each phase of construction, assuming the two
loudest pieces of equipment would operate simultaneously, as recommended by the FTA for
construction noise evaluations. This construction noise model includes representative sound levels
for the most common types of construction equipment and the approximate usage factors of such
equipment that were developed based on an extensive database of information gathered during the
construction of the Central Artery/Tunnel Project in Boston, Massachusetts (CA/T Project or "Big
Dig"). The usage factors represent the percentage of time that the equipment would be operating
at full power.

As shown in Table 6, construction noise levels would range from 87 to 88 dBA Leq when the two
loudest pieces of construction equipment per phase operate 25 feet from an individual receptor.
These predicted noise levels credibly represent worst-case conditions. Construction noise levels
under credible worst-case conditions would be reduced to 84 to 85 dBA Leq when the two loudest
pieces of construction equipment per phase operate 35 feet or further from an individual receptors.

and between the hours of 9:00 a.m. and 4:00 p.m. on Saturdays. No construction is
permitted on Sundays or holidays.
x Equip all internal combustion engine-driven equipment with intake and exhaust mufflers
that are in good condition and appropriate for the equipment.
x Prohibit unnecessary idling of internal combustion engines.
x Locate stationary noise-generating equipment, such as air compressors or portable power
generators, as far as possible from sensitive receptors as feasible. If they must be located
near receptors, adequate muffling (with enclosures where feasible and appropriate) shall
be used to reduce noise levels at the adjacent sensitive receptors. Any enclosure openings
or venting shall face away from sensitive receptors.
x Locate construction staging areas at locations that will create the greatest distance between
the construction-related noise sources and noise-sensitive receptors nearest the project site
during all project construction.
x Locate material stockpiles, as well as maintenance/equipment staging and parking areas,
as far as feasible from residential receptors.
x Designate a "disturbance coordinator" who would be responsible for responding to any
complaints about construction noise. The disturbance coordinator will determine the cause
of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be
implemented to correct the problem. Conspicuously post a telephone number for the
disturbance coordinator at the construction site and include in it the notice sent to neighbors
regarding the construction schedule.
The implementation of these reasonable controls would minimize disruption and annoyance at
existing noise-sensitive receptors in the project vicinity. Considering that the modernization
activity would last approximately two to four weeks per hole, and less than one construction season
in total, and that the vast majority of construction would occur more than 35 feet from nearby
receptors, the temporary exceedances of the Town’s Code of Ordinances would result in a less-
than-significant impact.
Impact 2: Exposure to Excessive Groundborne Vibration. Construction of the project
would potentially generate vibration levels exceeding the 0.25 in/sec PPV threshold
at historic homes adjoining the project site. The implementation of best
management practices would reduce the potential impact to a less-than-significant
level.
The California Department of Transportation (Caltrans) recommends a vibration limit of 0.5 in/sec
PPV for new residential and modern commercial/industrial structures, a vibration limit of 0.3
13
in/sec PPV for older residential structures, and a vibration limit of 0.25 in/sec PPV for historic
buildings. The Town recognizes a structure as historic if any one of the following apply:
x Any structure / site that is located within an historic district
x Any structure / site that is historically designated within the LHP overlay
x Any primary structure constructed prior to 1941, unless the Town has specifically
determined the structure has no historic significance or architectural merit.
Based on the Town’s definition of historic structures, this analysis uses a vibration limit of 0.25
in/sec PPV to conservatively assess the potential for vibration impacts.
Table 7 presents typical vibration levels that could be expected from construction equipment at a
distance of 25 feet. Project construction activities, such as drilling, the use of jackhammers, rock
drills, other high-power or vibratory tools, and rolling stock equipment (tracked vehicles,
compactors, etc.), may generate substantial vibration in the immediate vicinity. Jackhammers
typically generate vibration levels of 0.035 in/sec PPV, and drilling typically generates vibration
levels of 0.09 in/sec PPV at a distance of 25 feet. Vibration levels would vary depending on soil
conditions, construction methods, and equipment used.
Vibration levels are highest close to the source and then attenuate with increasing distance from
the source. Vibration levels at various distances can be calculated as follows1:
PPVEquipment = PPVRef (25/D)n (in/sec)
Where: PPVRef = reference PPV at 25 ft.
D = distance from equipment to the receiver in ft.
n = 1.1 ( the value related to the attenuation rate through ground)

Table 8 provides a summary of vibration levels expected from project construction equipment in
five-foot increments to show how vibration levels attenuate with distance from the source. The
construction of the project would generate vibration levels exceeding the 0.25 in/sec PPV threshold
at vibration-sensitive buildings when vibratory rollers are used within 25 feet. The 0.25 in/sec PPV
threshold would also be exceeded at vibration-sensitive buildings when excavators are used within
10 feet. The use of small tractors/loaders/backhoes, pavers, and other paving equipment would not
be expected to generate vibration levels exceeding the thresholds.

The following best management practices are assumed in this analysis:
x Smaller equipment (less than 18,000 pounds) shall be used near the property lines adjacent
to the residential buildings to minimize vibration levels. For example, a smaller vibratory
roller similar to a Caterpillar model CP433E vibratory compactor could be used when
compacting materials within 25 feet of vibration-sensitive buildings. Small
tractors/loaders/backhoes shall be used within 10 feet of vibration-sensitive buildings
instead of excavators.
x Designate a Disturbance Coordinator responsible for registering and investigating claims
of excessive vibration. The contact information of such person shall be clearly posted on
the construction site.
The implementation of these best management practices would reduce the potential vibration
impact to a less-than-significant level.
