Main Street Los Gatos, CA 95030 Re: 19 Highland Avenue – Response to Comments on Mitigated Negative Declaration Addendum Dear Sally: Kimley-Horn and Associates, Inc. (Kimley-Horn), acting as an “extension of Town staff” for the 19 Highland Avenue Project, has prepared the following responses to address the general comments raised in the comment letter prepared by Lisa Roberts and dated September 22, 2016. These responses address the comments from Sections II, III, and IV of the letter. The comment heading from each of these sections is provided in bold text below with the Town’s response following. Section II. The 2010 MND is no longer relevant and a new initial study is required. The Town does not concur that the 2010 MND is no longer relevant. The following text has been added to the MND Addendum: The 2010 MND is the relevant environmental document for the proposed project for the following reasons: The 2010 MND evaluated the construction of one single-family residence at 19 Highland Avenue in generally the same location within the property as the proposed project; and There have been no significant changes with regard to the surrounding land uses that would result in new impacts from what was previously disclosed in the MND; and There have been no changes to the Town’s General Plan designation or zoning classification on the project site from what was previously evaluated in the 2010 MND; and There have been no changes in circumstances in which significant new information is now available that was not available at the time the 2010 MND was adopted such Page 2 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 that new or more significant impacts would occur. Therefore, the MND adopted in 2010 by the Town retains informational value regarding the potential impacts associated with the proposed development of one single-family residence at the 19 Highland Avenue site. The Town is the Lead Agency under CEQA and has prepared this Addendum to address the potential for new or more severe environmental impacts as a result of the proposed project changes when compared to the baseline assuming buildout of the original project. A new Initial Study is not required because the information provided in the 2010 study is still applicable to the proposed project given the similarity between the two proposals; and because there have been no significant changes to the baseline conditions evaluated in the 2010 MND. Section III. An EIR is required because the there is substantial evidence that the proposed project may have significant environmental effects. While additional project-specific technical reports have been submitted by the applicant and peer- reviewed by the Town as part of project review, the Town has found that there is no substantial evidence that the project may have significant effects on the environment. As noted in Table 1 of the Addendum, the proposed project will have a smaller overall footprint, increased setbacks from the creek, and will remove fewer trees than the project evaluated in the 2010 MND. No changes in the baseline conditions have been identified that would result in new impacts or increase the severity of previously identified impacts. This section of the comment letter does not identify any potential for new significant impacts. Section IV. The Application must be denied for two separate and independent reasons: (A) There is substantial evidence that the 2010 MND prepared for the Orphan Project is not relevant to the Pearson Project and (B) There is substantial evidence – a fair argument – that the Pearson Project may have adverse environmental impacts. A. The addendum is incomplete, misleading, biased, and otherwise insufficient and improper. While the MND Addendum does explain changes in the project description as compared to the original project, the Town does not concur that the MND Addendum document is incomplete, misleading, biased, and otherwise insufficient and improper. The comment does not outline how any of the changes in the proposed project or additional project-specific information submitted as part of project review, would result in new or more significant impacts. Page 3 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 The MND Addendum is not misleading because it does not include or address public comment letters that provide contrary opinion to the conclusions in the Addendum analysis. This is not a requirement for an Addendum. The letters and reports submitted to the Town by members of the public are included as part of the administrative record and are provided to the Town’s decision making bodies for their consideration when considering a project application. A consultation with the California Department of Fish and Wildlife (CDFW) and the Regional Water Quality Control Board (RWQCB) is not required. The 2010 MND was circulated for public agency and public review prior to its adoption by the Town. The proposed project does not result in any new or additional impacts on resources managed by either the CDFW or the RWQCB. In fact, the proposed project has a smaller development footprint and creates larger setbacks from the creek and removes fewer trees than the 2010 original project. Similar to the 2010 original project the proposed project would not result in any impacts below the top of the creek channel. Therefore, no permits from CDFW are required. The addendum has found that the information in the 2010 MND is relevant, applicable to the proposed project and that no new CEQA document is required. Therefore, no new or additional CEQA analysis, including consultation with responsible agencies is required. B. Based on Evidence, the Application must be Denied on CEQA Grounds The Town does not concur that 2010 MND is not relevant to the proposed project. Please see Response 1 above. No evidence has been identified that the proposed project would result in new previously unidentified significant environmental impacts or would increase the severity of previously identified significant effects. Pursuant to CEQA State Guidelines Section 15064(f)(7), “Under case law, the fair argument standard does not apply to determinations of significance pursuant to section 15162, 15163, and 15164.” Woodland and Trees Neither the habitat nor the trees onsite have been identified as special status plant species that would require avoidance or additional mitigation. The habitat is identified as coast live oak/California bay woodland. This habitat type is not a critical habitat of a sensitive plant or animal species and has not been designated as sensitive habitat by any regional, state, of federal agencies. Information concerning threatened, endangered, and other special-status species that could occur in the project region was reviewed by a qualified biologist, including information from the following sources:  California Natural Diversity Database (CNDDB) and its associated species accounts (CNDDB 2016)  Federally listed species information for the vicinity from the website of the U.S. Fish and Wildlife Service (USFWS) (https://ecos.fws.gov/ipac/) Page 4 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130  California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants of California (CNPS 2016)  Relevant scientific literature, technical databases, and resource agency reports Visual confirmation of the absence of any sensitive plant species was conducted by a qualified biologist as part of the project biological resources report and confirmed by a peer review (including a site visit) by the Town’s biologist. The proposed removal of seven trees onsite is in compliance with the Town’s Tree Preservation Ordinance in which the intent of the ordinance is to, “regulate the removal of trees within the Town in order to retain as many trees as possible consistent with the purpose of this section and the reasonable use of private property.” Additionally, Mitigation Measure 2 requires that the applicant implement the recommendations under the Design Guidelines of the Arbor Resources Tree Report (February 15, 2010) section addressing tree retention and relocation, soil disturbance, mulching, trenching, drainage, facilities, and installation of new trees. The report also provides recommendations for Protection Measures before and during development, encompassing fencing, removal of hardscape, demolition, work within tree canopies, etc. The 2010 MND assumed that the original project would remove a total of 31 trees. A total of 18 trees were removed from the property by the previous owner. The proposed project would remove a total of seven additional trees. This would make a total of 25 trees to be removed which is less than the 31 proposed with the original project. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum. Habitats and Special Status Species The Town does not concur that the project site has the potential to contain habitat and Special Status Species. The project-specific HT Harvey Report (March 31, 2016, page 8) determined that the presence of sensitive bat species (both Townsend’s big-eared bat and pallid bat) were not expected to occur on the site after conducting focused surveys for roosting habitat. The Pacific Biology Report (June 2, 2016) simply states, “Finally, the proposed project includes the removal of numerous trees, including one particularly large oak tree (of compromised health) with numerous cavities. This tree could be used as a roost by bats, including special-status bats species such as pallid bat (Antrozous pallidus)…” but provides no further evidence that the tree is suitable for bat habitat. In response to this comment, the Town’s biologist visually inspected this tree and concluded (July 21, 2016 Letter Report), based on evidence from the site, that the tree is not suitable roosting habitat. As a result, the following text has been added to the addendum analysis: Page 5 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 As a result of public comment, the Town’s biologist (Live Oak Associates) visually evaluated tree #56, a large coast live oak tree, in July 2016. The tree was inspected with binoculars for the presence of features such as hollows, exfoliating bark or deep bark fissures that may potentially be used by bats for day roosting or maternity habitat. The tree was relatively easy to evaluate since it is in the process of succumbing to a bark beetle infestation and may also be highly drought-stressed, and therefore is almost barren of foliage. There are less than a half dozen places where limbs have fallen that have created small, relatively shallow hollows, ranging in diameter from about 6 to 8 inches. There are also a few areas of exfoliating bark as a result of the bark beetle infestation. These features do not provide potential maternity or roosting habitat for special status bats such as the Townsend’s big-eared bat or the pallid bat as these latter species do not use these types of features. Townsend’s big-eared bats require large cavernous areas such as buildings, mines, caves, and less frequently large hollows in the bases of trees; while the pallid bat typically uses buildings, caves, and rock crevices, so removal of tree #56 is not expected to affect either of these special status bat species that could potentially occur in the project vicinity. The small hollows and areas of peeling bark could be used as day roosts by certain common bat species, although these features wouldn’t provide maternity habitat for any of these species. Subsequently, Pacific Biology submitted a letter dated September 22, 2016 stating that pallid bats could roost onsite in tree #56 as pallid bats have been known to roost in oak trees elsewhere. The Town does not concur that the project has the potential to adversely impact sensitive bat species. The March 31, 2016 Biological Resources report, prepared for the project provides the following information regarding potential bat species, including focus surveys for sensitive bat species:  The Townsend’s big-eared bat (Corynorhinus townsendii), a State candidate for listing, historically occurred in the Project region. Unlike other bat species which seek refuge in crevices, the Townsend’s big-eared bat normally roosts in open, cavernous spaces, hanging in the top of a natural cavity, or in the top corner of ceilings and walls of an undisturbed room (this species is easily disturbed while roosting in buildings). A focused survey for suitable bat habitat on the Project site did not detect any large cavities suitable for roosting Townsend’s big-eared bats. Therefore, this species is not expected to occur on the Project site.  The pallid bat (Antrozous pallidus), a California species of special concern, historically occurred in the Project region. However, a focused search for bat roosting habitat during the site visit located no suitable habitat for pallid bat maternity roosts or large day roosts in trees within the Project site. Therefore, this species is not expected to occur on the Project site. The July 21, 2016 Live Oak report was focused on whether there was substantial evidence as to whether pallid bats would use the tree #56. Based on all the evidence provided in the technical reports, including Page 6 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 specific observations of tree #56, no evidence has been identified that pallid pats occupy this project site including tree #56. Nonetheless, the Town has required as a condition of approval, the recommendation provided in the July 21, 2016 letter from Live Oak Associates to remove tree #56 in a two -step process. The condition would require the tree to be removed outside of the bat winter torpor (hibernation) season with a qualified bat biologist present to avoid adverse impacts on non-special status bat species. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum. Creek The Town does not concur that the proposed project provides inadequate setbacks or is not consistent with the Guidelines and Standards for Land Use Near Streams (Guidelines). It should be noted that the setbacks recommended in Chapter 3 of the (Guidelines) are for the protection of creek bank slope stability. The proposed project maintains a minimum setback of 20 feet for the house structure and 10 feet for the driveway which is within the most conservative setback range of the 20-25-foot slope stability protection area established by the Guidelines. The Town will determine the appropriate setback, based on site conditions, and exceptions may be granted to allow a structure to be located within the slope stability protection area where a slope stability analysis is provided and maintenance of the stream will be provided. Within this range, the creek setbacks of the proposed project are consistent with the intermittent creek designation provided on page 3.8 of the Guidelines. With regard to the creek bank slope stability, a letter from the applicant’s geotechnical engineer (Upp Geotechnology, February 2016) notes that the proposed project would not present a slope stability hazard with a setback of 15 feet for the proposed structure (the structure has since been moved to a minimum 20-foot setback) and a 10-foot setback for the driveway. Additionally, the Town biologist (Live Oak Associates) has determined that a 20-foot setback is an adequate setback to preserve biological functions and values of the creek on the site. The Town biologist had also previously determined that a few areas of encroachment would result in less than significant impacts on the creek. The Guidelines were adopted by the Town in 2007 prior to the adoption of the 2010 MND. As such, the Town found the setbacks of the original project satisfactory for slope stability including the removal of up to 31 trees. The proposed project has increased the minimum setbacks from the top of bank compared to the original project and reduced the number of trees that are to be removed. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum. Page 7 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 Grading, Erosion, Size, Footprint, Relocation The Town does not concur that the changes in the project design would result in significant impacts on grading, or erosion. As noted in the project addendum, the proposed building footprint has been moved to increase the setback from the creek. As such, the proposed house has reduced the area outside of the Least Restrictive Development Area (LRDA) established by the Town’s Hillside Development Standards and Guidelines (HDSG). The HDSG are a relevant performance standard to reference in the analysis because the project site is located within the area to which these standards and guidelines apply. Development on this site must meet the requirements of the HDSG which seeks to minimize the amount of grading, soil disturbance, and manufactured slopes. While the total grading amounts for the proposed project increase by approximately 97 cubic yards, the proposed grading is able to be balanced onsite and eliminates the need for approximately 154 yards to be exported offsite. By moving the structure and driveway away from the creek, the total amount of retaining walls is reduced by 54% (from approximately 457 lineal feet to approximately 210 lineal feet) and reduces the overall height of the walls as no wall is proposed to be over six feet in height. These adjustments combined with the fact that the proposed project has reduced its lot coverage by more than 1,000 square feet means that more of the project site is left in its natural state and results in less soil disturbance during construction and fewer trees would have to be removed, particularly trees closer to the drainage. These changes would reduce the potential for erosion because there is less soil disturbance and the limits of construction are moved farther from the creek. None of the proposed design changes have been identified to result in increased adverse effects from grading or increased erosion. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum. Storm Drainage The proposed project results in a reduced need for bioswales because the project reduced the lot coverage by 1,000 square feet and included pervious pavers in the driveway. This reduced the amount of impervious surface on the project site and subsequently reduced the amount of the bioswale area needed. No other changes as a result of the proposed project were identified that would result in significant adverse changes to hydrological or water quality conditions from what was analyzed in the 2010 MND. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum. Page 8 kimley-horn.com 100 West San Fernando Street, Suite 250, San José, California 92113 (669) 800-4130 Other Aesthetic and Environmental Changes No changes to the aesthetic conditions evaluated as part of the 2010 MND have been identified. The architecture of the building as well as building materials, building size, and building setbacks is reviewed by the Town’s Consulting Architect as part of the Town’s Architecture and Site Permit process. All lighting on the exterior of the homes must comply with the Town’s buildings codes which prohibit light trespass over the property line. Exterior lights must be shielded to reflect the light downward and not outward. Light fixtures are reviewed by Town staff during the review of the building plans prior to the issuance of a building permit stage. No new potential adverse effects as a result of the drought conditions in California have been identified. Therefore, no new or more significant impacts as a result of the proposed project have been identified and the analysis within the 2010 MND is relevant to the analysis in the MND Addendum.

Jewell, AICP, LEED AP Senior Project Manager Town of Los Gatos Addendum to the Previously Adopted Mitigated Negative Declaration 19 Highland Avenue Architecture and Site Application S-15-077 October 2016 Prepared for: Town of Los Gatos Community Development Department 110 E. Main Street Los Gatos, CA 95030 Prepared by: Kimley-Horn and Associates 100 West San Fernando Street, Suite 250 San Jose, CA 95113 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 1 1.0 INTRODUCTION A. Determination This document constitutes an Addendum to the December 10, 2010 Initial Study/Mitigated Negative Declaration (2010 IS/MND, included in this document as Attachment 1) (Geier & Geier Consulting, Inc., 2010) originally prepared and adopted by the Town of Los Gatos (Town) for approval of the 19 Highland Avenue Project (hereafter referred to as the Original Project). This Addendum evaluates whether modifications/refinements to the proposed single-family residential home design, as revised July 11, 2016, (hereafter referred to as the proposed project) would result in any new or substantially more significant effects or require any new mitigation measures not identified in the 2010 MND. Similar to the Original Project, the proposed project would consist of the development of one single-family-home and driveway at 19 Highland Avenue. The proposed project differs from the Original Project because of changes to the architectural design of the proposed house and modifications to the project footprint to increase setbacks from the adjacent stream, reduce the number of trees to be removed, and avoid the need to export soils from the project site. As verified in this Addendum, the analyses and the conclusions in the 2010 MND remain current and valid. The proposed revisions to the Original Project, in the form of minor changes to the project design, would not cause new significant effects not identified in the MND nor increase the level of environmental effect to substantial or significant, and, hence, no new mitigation measures would be necessary to reduce significant effects. No change has occurred with respect to circumstances surrounding the proposed project that would cause new or substantially more severe significant environmental effects than were identified in the 2010 MND. In addition, no new information has become available that shows that the project would cause new or substantially more severe significant environmental effects which have not already been analyzed in the 2010 MND. Therefore, no further environmental review is required beyond this Addendum. This Addendum incorporates the mitigation measures detailed in the 20 10 MND. With this Addendum, the proposed project would still be within the framework of the evaluation for the Original Project as documented in the 2010 MND. B. Background An IS/MND was circulated based on the requirements of the California Environmental Quality Act (CEQA) in 2010. No comments were received on the document and the Planning Commission adopted the MND and the Mitigation Monitoring and Reporting Program when th e Original Project was approved on December 8, 2010. The Town approved a time extension in 2012 after which the property owner passed away and the property was placed on the market. The applicant 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 2 and current property owner purchased the property in 2015 an d submitted a new application derived from the previously approved project plans. Refinements to the project design constitute minor modifications to the original project that was evaluated in the 2010 MND, which necessitate subsequent environmental review/documentation under CEQA. Section 15164(b) of the CEQA Guidelines states that an Addendum to an adopted Mitigated Negative Declaration may be prepared if only minor technical changes or additions are necessary or none of the conditions described in Section 15162 (further described below under Section 4) apply. The 2010 MND is the relevant environmental document for the proposed project for the following reasons:  The 2010 MND evaluated the construction of one single family residence at 19 Highland Avenue in generally the same location within the property as the proposed project; and  There have been no significant changes with regard to the surrounding land uses that would result in new impacts from what was previously disclosed in the MND; and  There have been no changes to the Town’s General Plan designation or zoning classification on the project site from what was previously evaluated in the 2010 MND; and  There have been no changes in circumstances in which new information is now available that was not available at the time the 2010 MND was adopted such that new or more significant impacts would occur. Therefore, the MND adopted in 2010 by the Town retains informational value regarding the potential impacts associated with the proposed development of one single-family residence at the 19 Highland Avenue site. The Town is the Lead Agency under CEQA and has prepared this Addendum to address the potential for new or more severe environmental impacts as a result of the proposed project changes when compared to the baseline assuming buildout of the original project. C. Purpose of This Addendum The purpose of this Addendum is to evaluate whether the proposed project as currently proposed would result in any new or substantially greater significant effects or require any new mitigation measures not identified in the 2010 MND prepared for the original project. This Addendum, together with the 2010 MND will be used by the Town when considering approval of the proposed project. D. CEQA Framework for Addendum 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 3 For a proposed project with modification from an original approved project, State CEQA Guidelines (Sections 15162 and 15164) provide that an Addendum to an adopted Mitigated Negative Declaration (MND) may be prepared if only minor technical changes or additions are necessary or none of the following conditions calling for the preparation of a subsequent MND have occurred:  Substantial changes in the project which require major revisions to the MND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects;  Substantial changes with respect to the circumstances under which the project is undertaken which require major revisions to the MND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or  New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time of MND adoption, shows any of the following: A. The project will have one or more significant effects not discussed in the MND, B. The project will result in impacts substantially more severe than those disclosed in the MND, C. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponent declines to adopt the mitigation measure or alternative, or D. Mitigation measures or alternatives that are considerably different from those analyzed in the MND would substantially reduce one or more significant effects on the environment, but the project proponent declines to adopt the mitigation measure or alternative. Based on the analysis and evaluation provided in this Addendum, no new significant impacts would occur as a result of the proposed project, nor would there be any substantial increase in the severity of any previously-identified significant environmental impact. In addition, no new information of substantial importance shows that mitigation measures or alternatives that were previously found not to be feasible or that are considerably different from those analyzed in the 2010 MND would substantially reduce one or more significant effects on the environment. Therefore, no conditions described in Section 15162 of the CEQA Guidelines has occurred . For this reason, an addendum is the appropriate document that will comply with CEQA requirements for the proposed project. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 4 E. Adoption and Availability of the Addendum In accordance with CEQA Guidelines Section 15164(c), an addendum to an adopted MND need not be circulated for public review but can be included in or attached to the adopted MND and presented to the decision-making body. The decision-making body shall consider the Addendum with the adopted MND prior to making a decision on the project (CEQA Guidelines Section 15164(d)). Although not required, this Addendum is also available for public review at the Town of Los Gatos Community Development Department, 110 East Main Street, Los Gatos, California 95030, and will be made available as an Attachment to the Staff Report that will be provided when the project is scheduled for consideration by the decision-making body. 2.0 Project Description A. Project Location The project is located at 19 Highland Avenue in the Town of Los Gatos, within Santa Clara County (Assessor’s Parcel Number: 537-11-030). Please see Figures 1 and 2: Regional Map, and Vicinity Map, respectively. B. Proposed Project Components The proposed single-family residence would have three levels with the garage set to the lowest grade, stepping up to two floors of living space. The first floor of living space exits at grade to a dirt patio at the rear of the residence. The residence has a mode rn/contemporary architecture with roof forms that slope with the hillside. The proposed materials include: cedar siding and smooth finish stucco, with a standing seam metal roof . The proposed project is in compliance with the Town’s Hillside Development Standards and Guidelines (HDS&G) inclusive of grading and drainage criteria, allowable floor area, height, and architectural and landscape design. The only exception requested is in regard to development on slopes greater than 30 percent. The limited area of development on slopes greater than 30 percent is consistent with the approved placement of the residence from 2010. The proposed project has reduced HDS&G exception requests compared to the 2010 original project. The layout of the proposed project is shown in Figure 3 : Site Plan, the proposed grading for the site is shown in Figure 4: Grading and Drainage Plan, and the trees that are proposed to be removed are shown in Figure 5: Tree Inventory Plan. The proposed project includes landscaping along the perimeter of the development envelope, including trees to replace those trees that are proposed to be removed. The proposed landscape plan is shown in Figure 6 : Landscape Plan. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 5 C. Comparison of the 2010 Original and 2016 Proposed Projects The proposed project includes changes to the project design that reduce the overall impact of the proposed project compared to the original design. Examples of the design features that minimize the physical impacts on the project site include a reduction in the overall lot coverage by 1,065 square feet (approximately 14%); an increase in the creek setbacks to the garage and residence, and driveway; elimination of the need to export soil; a reduction in the overall length of retaining walls by 54%, and a reduction in the number of trees to be removed from 16 to 7 (a 56% decrease). These changes are tabulated in Table 1: Comparison of Project Components which provides a comparison of the 2010 original project and the 2016 proposed project. Although the floor area of the proposed project is approximately 211 square feet more than the original project, the proposed floor area is consistent with other homes in the vicinity. Moreover, the modified footprint of the home is 270 square feet less than the original project. The maximum proposed height is the same as the original project. Similar to the original project, the modified residence has been designed to conform to the natural topography of the site and run with the contours. The proposed project includes non-reflective colors and materials. The colors and materials of the proposed project residence (dark and light brown tones) are more compatible with the natural surroundings than the original project’s colors and materials which included taupe, “ochre” (yellowish or orange-brown), and “terra cotta” (brownish red). The proposed project would use stone and wood, a more natural element, compared to the original project which was planned to be stucco (with the exception of the stone wall covering the crawl space). 3.0 Analysis of Potential Environmental Effects The 2010 MND identified mitigation measures that would reduce or eliminate potential environmental effects of the original project to a less than significant level. All of the mitigation measures approved for the original project would also apply to the proposed project and no new mitigation measures are necessary. No new or substantially more significant adverse impact has been identified. 1) AESTHETICS The 2010 MND found that the project would have less than significant effects on scenic vistas, scenic resources, and the existing visual character of the site and its surroundings. The proposed project would remove 7 of the existing 86 protected trees onsite (nine fewer trees than originally proposed). The proposed design refinements would not result in additional impacts to aesthetic resources beyond those identified in the 2010 MND. Despite the minor changes proposed in the house and driveway locations, the overall nature and intensity of construction would not be substantially different than under the proposed project, and all construction activities would occur within the project site as was also evaluated in the 2010 MND. No mitigation measures are required for either the 2010 original or the proposed project. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 6 Table 1: Comparison of Project Components 1The difference in earthwork quantities account for soil shrinkage during the compaction process. 2010 Original Project 2016 Proposed Project Lot Size 1.04 acre 1.04 acre General Plan Hillside Residential, 0-1 unit/acre Hillside Residential, 0-1 unit/acre Zoning HR-2 ½, Hillside Residential Zone (2 ½ to 10 acres per dwelling with a minimum lot size of one acre) HR-2 ½, Hillside Residential Zone (2 ½ to 10 acres per dwelling with a minimum lot size of one acre) Floor Area: Main Level: Upper Level: Garage/Storage: Subtotal: (garage credit) Total Floor Area: 2,310 square feet 1,535 square feet 592 square feet 4,437 square feet -400 square feet 4,037 square feet 2,379 square feet 1,652 square feet 617 square feet 4,648 square feet -400 square feet 4,248 square feet Maximum Height Maximum Elevation: 25-feet 35-feet 25-feet 35-feet Lot Coverage - Residence - Driveway - Deck/Patios Total Lot Coverage ~ 2,642 square feet ~ 2,880 square feet ~ 1,927 square feet 7,449 square feet 2,372 square feet 3,583 square feet ~ 429 square feet 6,384 square feet Property Setbacks - Front: - North (left) Side: - South (right) Side: - Rear 190.0-feet 20.0-feet 24.0-feet 63.5-feet 185.0-feet 21.0 feet 25.0 feet 65.0 feet Creek Setbacks: - Residence/Garage: - Driveway: Minimum 10-feet Minimum 1-foot Minimum 20-feet Minimum 10-feet Area outside LRDA: ~1,363 square feet 1,182 square feet Grading: 342 cubic yards cut 188 cubic yards fill 154 cubic yards of export 439 cubic yards cut 429 cubic yards fill 0 cubic yards of export1 Retaining Wall Height: < 3 feet height: 0 feet 3-6 feet height: 394-feet > 6 feet height: 63-feet < 3 feet height: 106-feet 3-6 feet height: 104-feet > 6 feet height: 0-feet Retaining Wall Length: ~457-feet ~210-feet Tree Removal Proposed: 31 trees Removed: 15 trees Remaining to Remove: 16 trees Proposed: 7 trees (including one dying tree) 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 7 2) AGRICULTURE The proposed design refinements would not result in additional impacts to agriculture beyond those identified in the 2010 MND because there are no prime, unique, or statewide important farmlands in the project study area. The 2010 MND did not identify any impacts to agricultural uses; therefore, mitigation was not required. No new mitigation measures are required for the proposed refinements to the project design. No mitigation measures are required for either the 2010 original or the proposed project. 3) AIR QUALITY The proposed project design refinements would not result in additional impacts to air quality beyond those identified in the 2010 MND. The 2010 original project proposed a total cut of 342 cubic yards and total fill of 188 cubic yards of soil, resulting in the need to export approximately 154 cubic yards of material. The proposed project proposes a total cut of 439 cubic yards and total fill of 429 cubic yards. No export of earthwork would be required resulting in fewer construction trucks coming to and from the site during grading activities. It should be noted the additional grading is proposed to recess the home into the hillside in compliance with the Hillside Development Standards and Guidelines. The background conditions, construction equipment mix, and construction work hours identified in the 2010 MND have not notably changed and the proposed refinements would not result in any substantial change in the way the way the proposed house would be constructed . The modifications to the construction plan would not substantially change the intensity or duration of total construction activities identified in the 2010 MND. Therefore, as described in the 2010 MND, the proposed project would not exceed any Bay Area Air Quality Management District (BAAQMD) standards or contribute to air quality deterioration beyond BAAQMD projections. As was the case for the 2010 original project, mitigation is required to limit the proposed project’s construction-related dust, criteria pollutant, and precursor emissions, per BAAQMD- recommended Basic Construction Mitigation Measures. Mitigation Measure 1: To limit the project's construction-related dust, criteria pollutant, and precursor emissions, the following BAAQMD-recommended Basic Construction Mitigation Measures shall be implemented: a. All exposed surfaces (e.g. parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. b. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. c. All visible mud or 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. d. All vehicle speeds on unpaved roads shall be limited to 15 mph. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 8 e. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. f. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne taxies control measure Title 13, Section 2485 of California Code of Regulations). Clear signage shall be provided for construction workers at all access points. g. All construction equipment shall be maintained and properly tuned in accordance with manufacturer's specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. h. A publicly visible sign with the telephone number and person to contact at the Lead Agency regarding dust complaints shall be posted at the site. This person shall respond and take corrective action within 48 hours. The Air District's phone number shall also be visible to ensure compliance with applicable regulations. 4) BIOLOGY The proposed project design refinements would not result in additional impacts on biological resources beyond those identified in the 2010 MND. The proposed project has increased the setbacks of the house and driveway from the creek that traverses the project site. In March 2016, HT Harvey updated their previous biological resources report prepared in 1997 for the project site. The biological resources report determined that the proposed project did not result in any new or more significant impacts to biological resources. This report was peer reviewed by Live Oak Associates. Both HT Harvey and Live Oak Associates recommend a project condition with regards to completing a pre-construction tree-survey and pre-construction survey for migratory birds be included. As no special status plant or animal species were identified onsite, the project condition is proposed to ensure compliance with the Town’s Tree Protection Ordinance, and the Migratory Bird Treaty Act. Live Oak Associates also recommended a project condition relative to potential day-time roosting bat habitat of non-special status bat species that could utilize tree #56 to further address neighborhood concerns regarding the potential for bat species onsite . Inclusion of these project conditions is not a result of a new or more significant impact. No new impact has been identified because potential project impacts on non-sensitive upland habitats and associated common (non-sensitive) plant and animal communities do not meet the CEQA standard of having a substantial adverse effect, and are considered less than significant and no mitigation is required under CEQA. Tree Protection The proposed project has been redesigned to preserve nine (9) trees that were previously approved for removal in 2010. Comprehensive Tree Inventory Table(s) and Arborist Report(s) 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 9 were prepared for the subject property in 2010 and in 2016. The 2010 Arborist Report inventoried “protected” trees in proximity to the original project’s proposed development and located on the subject site or overhanging the subject site from neighboring properties. Under the “review of potential tree impacts” the 2010 Arborist Report identified 29 protected trees that “would either be removed or considered a loss” (#3-8, 12, 13, 15-17, 19, 21, 22, 24-28, 30, 37-40, 60-62, 64 and 68). The 2010 Arborist Report recommended that an additional two (2) trees be removed due to their failing health (#s 10, 46) for a total of 31 trees. Based on a site survey comparison with the 2010 Arborist Report, it appears that the property owner of the original project removed 15 trees that were previously approved for removal (tree #s 3-7, 10, 12, 15, 19, 24, 26, 28, 37, 64, 68) and three (3) trees which were not previously approved for removal (#s 55, 58, 67), for a total of 18 trees. The site survey also revealed that 16 of the 31 trees that were previously proposed for removal remain on the site. A Tree Inventory was prepared by Monarch Consulting Arborists LLC on May 10, 2016 and then revised on July 10, 2016 for the proposed project. Per the 2016 Inventory, the subject property contains a total of 86 trees1, including a grove of undisturbed trees on the nort herly portion of the lot that were not previously considered. Per the proposed project, seventy-nine (79) existing mature trees (92%) are to be retained while seven (7) trees will need to be removed. This includes tree #56, and while not directly affected by the proposed project, this tree also requires removal as it is infested with ambrosia (bark) beetles, is half-dead, and poses an unreasonable risk for failure. Additional trees would be planted to replace removed trees in accordance with the Town’s Tree Protection Ordinance. A landscape architect that is familiar with riparian and creek settings will recommend species and locations appropriate for the subject site. Potential impacts are considered less than significant and no additional mitigation is required. Creek Protection There are conflicting conclusions regarding the classification of the un-named tributary as either ephemeral or intermittent. This classification has been used as a benchmark for determining what the appropriate setback to the top of bank should be. Creek setbacks are at the discretion of the Town since no impacts to the creek channel below the top of bank would occur that would require a permit from either the Santa Clara Valley Water District or the Regional Water Quality Control Board. The Guidelines and Standards for Land Use Near Streams recommends setbacks for slope stability2, ranging from 10- to 15-feet for ephemeral streams and 20- to 25-feet for intermittent streams. In addition, establishment of a 10-foot wide setback between the top of bank and paved surfaces3 is also consistent with regional and state guidelines, provided 1 Tree count: 41 trees not previously inventoried + 45 trees previously inventoried (63 minus 18 removed). 2 Page 3.8, Chapter 3 of Guidelines and Standards for Land Use Near Streams, August 2005 and revised July 2006 3 The project will use permeable paver construction for the driveway surface. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 10 appropriate construction and post construction Best Management Practices (BMPs) are designed, implemented and maintained. Where a range is given, the Local Agency will determine the appropriate setback based on their existing priorities, permitting processes, and on-site conditions. Exceptions may be granted to allow a structure to be located within the slope stability protection area where a slope stability analysis is provided and maintenance of the stream will be provided, as is the case with this project. A letter from Upp Geotechnology, dated February 2016, notes that the proposed project would not present a slope stability hazard with a setback of 15 feet for the proposed structure (the structure has since been moved to a minimum 20-foot setback) and a 10-foot setback for the driveway. Additionally, the Town biologist (Live Oak Associates) has determined that a 20- foot setback is an adequate setback to preserve biological functions and values of the creek on the site. The Town biologist had also previously determined that a few areas of encroachment to within 16 feet from the top of the bank for the home and less than 10-feet for the driveway would result in less than significant impacts on the creek. The proposed project will provide a minimum setback of 20-feet from the top of bank with a majority of the home being setback further than 20 feet. A small portion of the home is cantilevered above the ground with a minimum setback of 16 feet. The driveway will have a minimum setback of 10 feet from the top of the creek bank. The proposed project would increase the setbacks from the Original Project which proposed minimum setbacks of 10 feet from the top of bank and 1 foot from the top of bank to the driveway. As such, the creek setbacks included with the proposed project are consistent with the Guidelines and Standards for Land Use Near Streams and would increase the amount of setback distance compared to the Original Project. Therefore, the proposed project would have no impact on the existing creek and no mitigation is required. Sensitive Bat Species As a result of public comment, the Town’s biologist (Live Oak Associates) visually evaluated tree #56, a large coast live oak tree, in July 2016. The tree was inspected with binoculars for the presence of features such as hollows, exfoliating bark or deep bark fissures that may potentially be used by bats for day roosting or ma ternity habitat. The tree was relatively easy to evaluate since it is in the process of succumbing to a bark beetle infestation and may also be highly drought-stressed, and therefore is almost barren of foliage. There are less than a half dozen places where limbs have fallen that have created small, relatively shallow hollows, ranging in diameter from about 6 to 8 inches. There are also a few areas of exfoliating bark as a result of the bark beetle infestation. These features do not provide potential maternity or roosting habitat for special status bats such as the Townsend’s big-eared bat or the pallid bat as these latter species do not use these types of features. Townsend’s big-eared bats require large cavernous areas such as buildings, mines, caves, and less frequently large hollows in the bases of trees; while the pallid bat typically uses buildings, caves, and rock crevices, so removal of tree #56 is not expected to affect either of these special status bat species that could potentially occur in the project vicinity. The small hollows and areas of peeling bark could be used as day roosts by 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 11 certain common bat species, although these features wouldn’t provide maternity habitat for any of these species. In conclusion, the changes between the original project and the modified project would not trigger any of the conditions listed in CEQA Guidelines Sections 15162 and 15164, requiring preparation of a subsequent or supplemental Mitigated Negative Declaration. While new information regarding the creek location has become available, the modified project will have a 20-foot setback from the top of the creek bank, such that there would be no significant environmental effects not already mitigated in the 2010 IS/MND. Overall, the modified project would result in fewer environmental impacts than the original project, due to the increased setback from the creek (from 15-feet in the original project to 20-feet in the modified project). The conclusions in the 2010 IS/MND remain current and valid. The mitigation measures included in the 2010 IS/MND remain applicable and would be applied to the modified project. Therefore, an Addendum prepared by the Town of Los Gatos would satisfy the requirements of CEQA. Mitigation Measure 2: With review and approval by the Town, all recommendations made by Arbor Resources (February 15, 2010) will be implemented to eliminate or minimize construction-related impacts on the trees to be retained. Recommendations are listed under Section 5.0, Recommendations, of the arborist’s report. These include recommendations under the Design Guidelines section addressing tree retention and relocation, soil disturbance, mulching, trenching, drainage, facilities, and installation of new trees. The report also provides recommendations for Protection Measures before and during development, encompassing fencing, removal of hardscape, demolition, work within tree canopies, etc. The report’s recommendations are included as Attachment 1 of the Initial Study. 5) CULTURAL RESOURCES The extent and intensity of construction activities would not vary substantially relative to that evaluated in the 2010 MND, and mitigation measures prescribed in the 2010 MND would still be applicable and necessary to reduce potentially significant of impacts under the proposed project. The 2010 MND found that the project would have less‐than‐significant effects with mitigation on archaeological resources and human remains. While the proposed project would include increased excavation for building foundations and bioswales, the potential effects on archaeological resources and human remains would be the same as the original project and would be reduced to less than significant with implementation of Mitigation Measures 3 through 6 which would remain the same for the proposed project. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 12 Mitigation Measure 3: In the event that archaeological traces are encountered, all construction within a 50-meter radius of the find shall be halted, the Community Development Director shall be notified, and an archaeologist shall be retained to examine the find and make appropriate recommendations. Mitigation Measure 4: If human remains are discovered, the Santa Clara County Coroner shall be notified. The Coroner will determine whether or not the remains are Native American. If the Coroner determines that the remains are not subject to his authority, he will notify the Native American Heritage Commission, who shall attempt to identify descendants of the deceased Native Americans. Mitigation Measure 5: If the Community Development Director finds th at the archaeological find is not a significant resource, work will resume only after the submittal of a preliminary archaeological report and after provisions for reburial and ongoing monitoring are accepted. Provisions for identifying descendants of a deceased Native American and for reburial will follow the protocol set forth in CEQA Guidelines Section 15064.S(e). If the site is found to be a significant archaeological site, a mitigation program shall be prepared and submitted to the Community Developmen t Director for consideration and approval, in conformance with the protocol set forth in Public Resources Code Section 21083.2. Mitigation Measure 6: A final report shall be prepared when a find is determined to be a significant archaeological site, and/or when Native American remains are found on the site. The final report shall include background information on the completed work, a description and list of identified resources, the disposition and curation of these resources, any testing, other recovered information, and conclusions. 6) GEOLOGY The proposed refinements would not result in substantially different geophysical impacts beyond those identified in the 2010 MND. While the proposed project involves proposed changes to the timing and location of some construction activities, these changes do not represent a substantial deviation from the project analyzed in the 2010 MND, and the conclusions of the 2010 MND remain valid. A Geotechnical Memo by UPP Geotechnology was submitted for the proposed project in 2016 and peer reviewed by Amec Foster Wheeler Environment & Infrastructure, Inc. Implementation of Mitigation Measure 7 would remain the same for the proposed project. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 13 Mitigation Measure 7: A design-level geotechnical investigation and final construction plans shall be completed and reviewed as specified by Geomatrix, Inc. (see Attachment 2 of the Initial Study for detailed recommendations). 7) GREENHOUSE GAS EMISSIONS The proposed project would result in a similar (or potentially reduced) duration and intensity of construction activities relative to the original project, and both the original and proposed project would be operationally identical. As such, the proposed construction modifications would not result in an increase in greenhouse gas emissions or related impacts to global climate change or conflicts with applicable climate change plans, policies, or regulations. The 2010 MND found the project would have a less than significant effect on greenhouse gas emissions. The proposed changes to the project would not result in any new or substantially more severe effects due to greenhouse gas emissions. 8) HAZARDS AND HAZARDOUS MATERIALS The proposed design refinements would not result in additional impacts to hazards or hazardous materials beyond those identified in the 2010 MND because there are no hazardous wastes or hazardous materials at the project site. The 2010 MND did not identify any impacts from hazardous materials or lack of defensible space for project located within a fire hazard area. Therefore, mitigation was not required. No new mitigation measures are required for the proposed refinements to the project design. No mitigation measures are required for either the 2010 original or the proposed project. 9) HYDROLOGY AND WATER QUALITY The proposed project would be required, as under the original project, to comply with all applicable water quality regulations during and following construction activities. The project site is not located within a 100-year flood plain. As is the case with the 2010 MND, compliance with stormwater regulations would preclude the potential for significant impacts to receiving water bodies, including the creek at the project site. No mitigation measures are required for either the original or the proposed project. 10) LAND USE AND PLANNING The proposed project would require the same entitlements, permits, and other approvals as the original project. No mitigation measures are required for either the original or the proposed project. 11) MINERAL RESOURCES The proposed refinements would not result in additional impacts to mineral resources beyond those identified in the 2010 MND and because the project site is not located within an area of 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 14 known mineral resources, either of regional or local value, the 2010 MND did not identify any impacts to mineral resources; therefore, mitigation was not required. No new mitigation measures are required for the changes to the original project. No mitigation measures are required for either the original or the proposed project. 12) NOISE The proposed project would not result in additional impacts to noise beyond those identified in the 2010 MND. The proposed not result in design or operational changes to the project site or surrounding area from that analyzed in the 2010 MND. The overall intensity, equipment mix, duration, and proximity to sensitive receptors would not be notably different than under the original project. The 2010 MND found that the project would have less‐than‐significant impacts related to noise. The proposed project would have no change on the project’s noise operations; therefore, it would not affect the MND noise analysis of the original project. No mitigation measures needed for either the original or the proposed project. 13) POPULATION AND HOUSING The proposed project would not have any effect on population, housing, or employment in the Town or region at large, as is the case for the original project. No adverse impacts would occur in this regard. No mitigation measures are required for either the original or the proposed project. 14) PUBLIC SERVICES The proposed project would not result in additional impacts to public services/utilities beyond those identified in the 2010 MND because they would not result in changes to existing public services those evaluated in the 2010 MND for the original project. The 2010 MND did not identify any potentially significant impacts to public services; therefore, mitigation was not required. No new mitigation measures are required for the proposed project. 15) RECREATION The proposed design modifications would not result in additional impacts to recreational facilities beyond those identified in the 2010 MND. The 2010 MND did not identify any permanent impacts to recreational resources or facilities. No mitigation measures area required for either the original or the proposed project. 16) TRANSPORTATION The 2010 MND found that the project would have less‐than‐significant effects on transportation and circulation. The proposed project would result in no changes to operational trip generation; therefore, it would not affect the 2010 MND analysis related to transportation and circulation. No mitigation measures area required for either the original or the proposed project. 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 15 17) UTILITIES AND SERVICE SYSTEMS The proposed project would not require or result in the construction or expansion of any public utilities beyond those required for the original project. Temporary short‐term and operational demands on public utilities or other infrastructure would not measurably change under the proposed project and therefore impacts would be less than significant and no mitigation measures are required. 18) MANDATORY FINDINGS OF SIGNIFICANCE The potential impacts of the proposed project with regard to biological resources, cultural resources, and direct and indirect effects on human beings would be comparable to the original project, and potentially reduced with regard to biological resources given the reduction in trees to be removed and increased setbacks from the creek under the proposed project. As impacts under the proposed project would be similar to or reduced relative to the original project, impacts would be less than significant in this regard and no mitigation measures are required. 4.0 Recommendation That the Town of Los Gatos Planning Commission finds on the basis of substantial evidence in the light of the whole record that the proposed modifications to the original project are within the scope of the original 2010 MND analysis and will not cause any new significant environmental impacts, substantially increase previously identified impacts, nor require any new or modified mitigation. In making this finding, the Planning Commission has considered evidence presented by Town Staff, the applicant, and other interested parties and has determined that: (1) NO substantial changes are proposed in the project which will require major revisions of the previously adopted Mitigated Negative Declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; (2) NO substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previously adopted Mitigated Negative Declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or (3) New information which was not known and could not have been known with the exercise of reasonable diligence at the time the previously adopted Mitigated Negative Declaration was adopted, does NOT show any of the following: (A) The project will have one or more significant effects not discussed in the previously adopted Mitigated Negative Declaration; 19 Highland Avenue – S-15-077 Town of Los Gatos Addendum – Mitigated Negative Declaration October 2016 16 (B) Significant effects previously examined will be substantially more severe than shown in the previously adopted Mitigated Negative Declaration; (C) Mitigation measures or alternatives previously found not to be feasib le would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or (D) Mitigation measures or alternatives which are considerabl y different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative. Based on the foregoing, it is concluded that the analyses conducted and the conclusions reached in the Final MND adopted on December 10, 2010 remain valid. The proposed revisions to the project would not cause new significant impacts not identified in the 2010 MND, and no new mitigation measures would be necessary to reduce significant impacts.

Jewell, AICP, LEED AP Kimley-Horn 555 Capitol Mall, Suite 300 Sacramento, CA 95814 RE: Biological Evaluation Peer Review for the 19 Highland Avenue project, located in the Town of Los Gatos, Santa Clara County, California (PN 2035-01). Dear Mr. Jewell: At the Town of Los Gatos’ request, Live Oak Associates’ (LOA) ecologist Pamela Peterson conducted an additional site visit on July 19, 2016 to the approximately one-acre 19 Highland Avenue project site. The one-acre site is located approximately 0.5 miles east of the Highway 17/Los Gatos Blvd. interchange at 19 Highland Avenue (APN 529-37-033) in the Town of Los Gatos, Santa Clara County, California. The additional site visit was for the purpose of evaluating a large coast live oak (Tree Tag #56) for potential bat habitat and to evaluate a small reach of the on-site creek where the alignment appears to have moved locations sometime in the period between 1996 and 2015 based on current and previous site plans for the property. For the latter, we were requested to evaluate the existing condition of this reach of the creek and determine whether the potential change in the creek’s alignment has resulted in, or could in the future result in, any potential biological issues. Background Review. Prior to the site visit, LOA reviewed two site plans provided to the Town by the project proponent, one that was prepared in 1996 by Westfall Engineers and one prepared in 2015 by Peoples Associates. Additionally, we reviewed the Appellant’s biological report with regard to their assertion that a single large coast live oak (Tag #56) provided habitat for bats, including the pallid bat (Antrozous pallidus) which is a state species of concern. Habitat for Special Status and Non Special Status Bats. The large coast live oak tree was evaluated visually and with binoculars for the presence of features such as hollows, exfoliating bark or deep bark fissures that may potentially be used by bats for day roosting or maternity habitat. The tree was relatively easy to evaluate since it is in the process of succumbing to a bark beetle infestation and may also be highly drought-stressed, and therefore is almost barren of foliage. There are less than a half dozen places where limbs have fallen that have created small, relatively shallow hollows, ranging in diameter from about 6 to 8 inches. There are also a few areas of exfoliating bark as a result of the bark beetle infestation. These features do not provide potential maternity or roosting habitat for special status bats such as the Townsend’s big-eared bat or the pallid bat as these latter species do not use these types of features. Townsend’s big- eared bats require large cavernous areas such as buildings, mines, caves and less frequently large Appendix A hollows in the bases of trees; while the pallid bat typically uses buildings, caves, and rock crevices, so removal of the tree is not expected to affect either of these special status bat species that potentially occur in the project vicinity. The small hollows and areas of peeling bark could be used as day roosts by certain common bat species, although these features wouldn’t provide maternity habitat for any of these species. The removal of the tree would not represent a significant loss of bat roosting habitat, however removal could impact a few individuals (based on the limited availability of roosting features, this number would be extremely low) of more common bat species, in the unlikely event individuals are roosting at the time the tree is removed. This potential impact could be avoided simply by removing the tree via a two-step process over two consecutive days outside of the bat winter torpor season, i.e. outside of the time period from mid-October through the end of March, under the supervision of a qualified biologist. To implement the two-step process, in the afternoon of the first day, limbs and branches would be removed by a tree cutter using chainsaws only and chipped on the site to create noise and disturbance. Limbs with cavities, crevices, exfoliating bark or deep bark fissures would be avoided, and only branches or limbs without those features would be removed. This action would allow bats to leave during the night after the first day of the two-step removal process, thus increasing their chances of finding new roosts with a minimum of potential predation during daylight hours. The tree would then be removed the second day. The bat biologist would not be required to be present on the second day (i.e., day of actual tree removal), as the activity, noise, and vibrations of the chainsaw and chipping activity as well as the physical and visual change of the tree would deter bats from returning to the tree after their nightly flight. Creek Alignment Evaluation. LOA also evaluated a short reach of the on-site creek. According to the 1996 site plan (Westfall Engineers), the creek alignment for this reach used to occur further to the north than its present location as depicted in the 2015 site plan (People’s Associates). In the field, it appeared that the change may have been a natural process which occurred as a result of the erosion of a steep bank on the adjacent property to the north which subsequently resulted in the channel following a new alignment around that area to the south. It appears that this occurred quite some time ago as the area of the old alignment is now densely vegetated and the creek channel itself in this location is undifferentiated from those reaches immediately up and down stream of this area. In LOA’s opinion, the change in the creek alignment does not result in any current or future potential biological issues for the site or for the proposed project. Thank you once again for allowing us to assist you in this matter. If you wish to discuss any of our findings, conclusions or recommendations, please feel free to contact me at 408-281-5884 or Rick Hopkins at 408-281-5885.

Creek Bank Stability Mr. Ryan Do provided additional peer review comments via email dated 12 February 2016 regarding the proximity of the proposed home and driveway to a creek bank and the stability of the creek bank. The email included the following review comments: Comment: Regarding the structure, the report should provide a stability analysis for Section C-C' where the structure is within 20 feet of the adjacent creek, or add language indicating foundations within this zone must extend to an elevation that is lower than the bottom elevation of the adjacent creek. Based on our review, the proposed residence is about 15 feet (measured horizontally) from the bottom of the creek bank at its closest point. The relative elevation difference between the ground surface and the bottom of the creek channel at that location is about 5 feet. Based on our subsurface exploration, we anticipate about 3'/2 to 4 feet of non - supportive soil mantling the supportive Santa Clara formation materials/Franciscan assemblage bedrock. We recommended that footings for the residence be constructed at least 1 foot into the Santa Clara formation or Franciscan assemblage. Thus, the bottom of footings will be within about 6 inches above the bottom of the creek channel. In our opinion, an elevation rise of 6 inches over a horizontal distance of 15 feet (or an incline of about 2 degrees from the bottom of the creek channel) does not present a slope stability hazard. Comment: Regarding the driveway, the report should include a stability analysis or otherwise discuss the depth and steepness of the creek bank adjacent to the driveway at critical locations (where driveway is closest to the creek and/or where steepest creek banks are). We also evaluated the slope stability and proximity of the creek bank at several locations along the driveway. The downslope side of the driveway is shown to be supported by block retaining walls up to a maximum retained height of 4 feet. We recommend that the wall extend below grade, such that the bottom course of block is founded in the underlying Santa Clara formation or Franciscan assemblage bedrock. Based on our subsurface study, we anticipate supportive materials to be about 2 to 3 feet below existing ground surface along the alignment. Taking these depths to support into account, we anticipate that the retaining wall around the proposed fire -truck turnaround at the entrance to the site will be founded at or below the elevation of the bottom of the creek bank. Near the middle of the driveway where the creek gets closest (bottom of the channel will be about 10 feet horizontally from the driveway retaining wall), we anticipate that the bottom course of blocks will be about 1 foot above the bottom of the creek channel. In our opinion, an elevation rise of 1 foot over a horizontal distance of 10 feet (or an incline of about 6 degrees from the bottom of the creek channel) does not present a slope stability hazard.
