Attachment 06TOWN OF Los GATOS COMMUNITY DEVELOPMENT DEPARTMENT Planning Division (408) 354-6874 Fax (408) 354-7593 December 5, 2017 David Bunn, Director California Department of Conservation Division of Land Resource Protection 801 K Street, MS 14-15 Sacramento, CA 95814-3528 CIVIC CENTER 110 E. MAIN STREET Los GATOS, CA 95030 Subject: Notice of Receipt of Petition for Cancellation of Land Conservation Contract No. 75-913 (Santa Clara Recorder's Office Document #4954827) and Preliminary Evaluation of the Required Five Consistency Findings Dear Mr. Bunn, Pursuant to Government Code Section 51284.1 (a), we are sending you this Petition for Cancellation of Williamson Act Contract No. 75-913 (Santa Cara Recorder's Office Document #4954827) for your review and comment. Enclosed are petition materials submitted by the current landowners, Surrey Farms Group, LLC (Linda Ramsbottom), Walter -Robert, LLC (Larry Dodge), and Twin Oaks Hike, LLC (Tom Dodge), for removal of an approximately 17.8-acre parcel from the Williamson Act program. The applicant is petitioning for cancellation of the contract in order to subdivide the 17.55-acre site into 12 lots for future development of 10 new single-family residences (plus one lot for private streets, and one open space lot). The following information is provided to assist you in your evaluation of the petition and in providing comments. Soil Classification; Other Land Water Availability: Water service would be provided by the San Jose Water Company. Eight - inch water lines would be extended along the proposed Private Streets, connecting with existing water lines in Twin Oaks Drive at the western project boundary, Brooke Acres Drive at the southern boundary, and Cerro Vista Court at the northern project boundary. Farming History: The site was used for orchards in the 1930s (and possibly the 1940s), but the orchards were removed by 1948. The site does not appear to have been in agricultural use since that time. The surrounding properties are all developed with single family homes, with the exception of the Hillbrook School, an elementary school which shares a portion of the property's northern boundary. 1 INCORPORATED AUGUST 10, 1887 1t, ATTACHMENT 6 Petition Documents: Also included for your review, are documents provided by the applicant and related to the cancellation process such as the petition for cancellation, a copy of Land Conservation Contract No. 75-913 (Santa Clara Recorder's Office Document #4954827), a copy of the recorded notice of non -renewal, findings prepared by the applicant, an area map, a biological memo, current market value estimate, and a shallow soil sampling report. Town Staff Evaluation: Below is our preliminary evaluation of the five required Consistency findings for cancellation of Land Conservation Contract No. 75-913 (Santa Clara Recorder's Office Document #4954827). This preliminary analysis is based on evaluating the proposed alternate use against the General Plan policies that would apply if the proposed zoning and General Plan designation were approved, as well as addressing the five Consistency findings from Town staff's perspective. 1. That the cancellation is for land on which a Notice of Nonrenewal has been served, pursuant to Section 51245 of the Government Code. A Notice of Nonrenewal for the 17.8-acre property was accepted by the Town on April 28, 2015, and recorded by the County Recorder on October 31, 2017, and was assigned Document No. 23789473. Based on the fact stated above, staff believes that Finding No. 1 can be made. 2. That the cancellation is riot likely to result in the removal of adjacent lands from agricultural use. None of the adjacent lands are under agricultural use or zone, therefore staff does not believe that removal of the 17.8-acre parcel from Contract restrictions will result in removal of adjacent land from farming; therefore, staff believes this finding can be made. 3. That the cancellation is for an alternate use that is consistent with the provisions of the Town's General Plan. The 2020 General Plan Land Use Element designates the project site as Agriculture. In 1988, the Town Council adopted Resolution No. 1988-230, which required amendment of the General Plan and Hillside Specific Plan designations to reflect rezoning of properties subject to Williamson Act contracts. Therefore, as part of a subsequent General Plan update, all Williamson Act lands were redesignated to Agriculture. Prior to this redesignation, the project site was designated in the Town's 1961 General Plan as Residential (0 to 2 families per acre). Since the Williamson Act contract is proposed to be cancelled, the project site's General Plan designation will, once again, require amendment pursuant to Resolution 1988-230 if the cancellation is approved. 2 The 2020 General Plan designates the area immediately west and southwest of the site as Low Density Residential (0 to 5 units per acre), while contiguous areas to the north, east, and southeast are designated as Hillside Residential (0 to 1 unit per acre). In connection with this petition for cancellation the Town is processing an application to change the General Plan Designation to Hillside Residential and rezone the property from Resource Conservation to Hillside Residential (0 to 1 units per acre). At 0.57 unit per acre, the proposed density would be consistent with the Hillside Residential designation. The Draft Environmental Impact Report for the project (available with other project related documents online here: http:1Jwww.losgatosca.gov/2390/T) includes the following table of applicable General Plan Policies: General Plan Policies Project Consistency Analysis Land Use Element Prior to entering into a Williamson Act contract, the Goal LU-1: To preserve, promote, and project site was designed for residential use at a density protect the existing small-town character higher than the proposed density.

LU-1.3: Preserve existing trees, natural vegetation, natural topography, and riparian and wildlife habitats, and promote tasteful, high quality, well designed, environmentally conscious and diverse landscaping in new developments. Goal CD-4: To preserve existing trees, natural vegetation, natural topography, riparian corridors and wildlife habitats, and promote high quality, well designed, environmentally sensitive, and diverse landscaping in new and existing developments. CD-4.3: Trees that are protected under the Town's Tree Preservation Ordinance, as well as existing native, heritage, and specimen trees should be preserved and protected as a part of any development proposal. Project implementation would retain about 83% of the existing protected trees (about 485 out of a total of 585), removing approximately 70 protected trees (12%) and transplanting about 30 protected trees (5%). Proposed roads and lots are mostly located in areas that either have been disturbed (i.e., equestrian ring, dirt access road) or covered by less sensitive vegetation types (i.e., non-native annual grassland, ruderal). Approximately 0.51 acre of mixed oak woodland would be removed, but about 4 acres of mixed oak woodland would be retained, including the oak woodland located on the 3.62-acre parcel (proposed Common Lot B) in the southeastern portion of the site, which is proposed to be retained as open space (see Impact 4.3-10 in Section 4.3, Biological Resources, for more discussion). Implementation of Mitigation Measures 4.3-10a, Tree Protection Measures, and 4.3- 10b, Tree Mitigation and Monitoring Plan, would ensure that replacement tree plantings meet ordinance tree replacement requirements. As indicated in Impact 4.3-8, project implementation would directly impact the swale and its associated oak riparian habitat. Grading, filling or trenching within the drip line or tree protection zone of native riparian trees would be deemed a direct impact on trees within the riparian zone. Project implementation has the potential to adversely affect riparian habitat associated with Ross Creek and the swale, a potentially significant impact. However, implementation of Mitigation Measure 4.3-8, Creek Protection, would reduce these impacts to a less - than -significant level. LU-4.2: Allow development only with adequate physical infrastructure (e.g. transportation, sewers, utilities, etc.) and social services (e.g. education, public safety, etc.). LU-4.4: Project applicants shall evaluate and provide appropriate mitigation measures to reduce impacts on urban services including schools, utilities, police, and fire. Existing services and utilities are currently provided to existing adjacent surrounding residential development. The project would include extension of roadways and utilities onto and throughout the site pursuant to Town requirements and agency regulations. Project implementation would enhance secondary emergency access to residents on Twin Oaks Drive and Brooke Acres Drive. The development of each lot will be required to adhere to the Town's Architecture and Site (A&S) review process, which would reduce impacts to urban services because of recommendations, oversight, and approval authority of the Town and relevant public service agencies. For a discussion of project consistency with these policies, see policy consistency analysis in Section 4.12, Public Services and Utilities. The project would be required to pay school fees according to SB 50 and these 4 fees will reduce impacts on schools. Community Design Element Goal CD-3: To require utilities, landscaping and streetscapes to contribute to Los Gatos's high -quality character. CD-3.1: Encourage the undergrounding of utilities on substantial remodels. CD-3.2: Street and structural lighting shall be required to minimize its visual impacts by preventing glare, limiting the amount of light that falls on neighboring properties, and avoiding light pollution of the night sky. CD-3.3: Consider new street lighting only when required for safety. Prior to development of each project lot, the proposed home design and landscape plan for each residence will be subject to A&S review. A&S review will also evaluate the potential for glare, shading, and nighttime illumination impacts due to exterior lighting on future homes. General Plan Policy TRA-7.8 prohibits the installation of new public street lights on hillside streets. As indicated on the proposed Utility Plan (Figure 3-7), all required utilities would be underground. CD-5.1: Street standards shall recognize the existing character of the neighborhood, safety, and maintenance. Proposed pavement and right-of-way widths would meet Hillside standards for cul-de-sacs. Proposed Street A would have a 24-foot paved width with 46-foot right-of- way width. Proposed Street B, (providing access for up to six lots) would have a 22-foot paved width with 44-foot right-of-way width. Goal CD-6: To promote and protect the physical and other distinctive qualities of residential neighborhoods. CD-6.1: Reduce the visual impact of new construction and/or remodels on the Town and its neighborhoods. CD-6.2: Balance the size and number of units to achieve appropriate intensity. CD-6.4: New homes shall be sited to maximize privacy, livability, protection of natural plant and wildlife habitats and migration corridors, and adequate solar access and wind conditions. Siting should take advantage of scenic views but should not create significant ecological or visual impacts affecting open spaces, public places, or other properties. Future homes proposed on project lots would be subject to A&S review, and visual compatibility of proposed home designs will be considered at that time. With respect to achieving the appropriate intensity, project lots would fall within the range of lot sizes that surround the project site with lower lots smaller and upper lots larger, consistent with the lot size pattern that occurs in the immediate project vicinity. Therefore, the project would protect the quality of life for surrounding residences and blend with the established character of the area. As indicated in Impact 4.2-3, the project would not substantially degrade the visual character of the sites or its surroundings. Provision of landscape trees and shrubs along project boundaries and roads, as well as maximizing setbacks of proposed potential building envelopes from existing adjacent residences, would help to maximize privacy of adjacent residences and screen views of future homes from these residences. Maximizing setbacks of homes from the swale that traverses the site would help to protect the riparian habitat. See discussion below under the Hillside Standards and Guidelines consistency analysis table (first row) relating to solar access and wind conditions. Issues relating to taking "advantage of scenic views" would be considered during the A&S review process for each individual home. 5 Goal CD-7: To preserve the quality of the private open space throughout Los Gatos. CD-7.1: Maximize quality usable open space in all new developments. Private open space associated with the 10 single-family residences would be provided as yards and hillside on the 10 project lots. In addition, the project would provide to the public approximately 3.6 acres of open space in the southeast corner of the site and a pedestrian/ equestrian trail that would provide an important connection/link between the Shannon Road neighborhood with the Kennedy Road neighborhood. The soil of the subject parcel is classified as "Other Land" on the Santa Clara County Important Farmland Map. This classification is land that is not included in any other mapping category. Our understanding is that this category is given to this site because of the site's size under 40 acres, its current vacant state, and the fact that it has urban development on all sides. Based on these facts, staff believes that the proposed alternate use is not inconsistent with the Town's General Plan policies and therefore, believes Finding No. 3 can be made. 4. That the cancellation will not result in discontiguous patterns of urban development. The surrounding parcels are located in a developed residential area of the Town of Los Gatos. Zoning of adjacent properties include Single Family Residential (R-1) and Hillside Residential (HR), including the Hillbrook School which shares part of the property's northern boundary. No vacant, undeveloped, or agricultural lands are adjacent to the subject property. Therefore, staff believes the proposed cancellation will not result in discontiguous patterns of urban development. Based on the facts stated above, staff believes Finding No. 4 can be made. 5. That there is no proximate, non -contracted land which is both available and suitable for the use to which it is proposed that the contracted land be put, or that development of the contracted land would provide more contiguous patterns of urban development than development of proximate non -contracted land. The applicant provided a map and a list identifying similar sized non -contracted parcels within a 3-mile radius of the subject parcel, and addressed utilizing any of the non - contracted parcels for the proposed use. The applicant included information on the map regarding the suitability of those parcels. Staff believes that the applicant has done a reasonable search to find a non -contracted parcel that can be used for the alternate use and therefore Finding No. 5 can be made. We request that you send us your comments regarding the proposed cancellation within 30- days from the receipt of this letter. 6 If you have any questions, 1 can be contacted by phone at (408) 399-5706 or by email at jarmer@losgatosca.gov.

The Town Council may grant tentative approval for cancellation of a WAC only if it makes one of the following findings: (1) That the WAG cancellation is consistent with the purposes of the Williamson Act. (2) That the WAC cancellation is in the public interest. For purposes of Government Code section 51282(a)(1) cancellation of a WAC shall be consistent with the purposes of the Williamson Act only if the Town Council makes all of the following findings: A. That the WAC cancellation is for land on which a notice of nonrenewal has been served pursuant to Section 51245. The notice of nonrenewal was filed and recorded on October 31, 2017 (Document #23789473) by the landowners and is consistent with the Williamson Act. B. That the WAC cancellation will not result in the removal of adjacent lands from agricultural use. The subject property (APN 532-16-006) ("Property") is owned by Surrey Farms Estates, LLC. The Property is surrounded by lands that are not designated prime agricultural land and are not under WACs. Therefore, the cancellation is not likely to result in removal of adjacent lands from agricultural use. C. That the WAC cancellation is for a proposed alternative use, which is a single-family residential subdivision that includes 10 single-family lots and one open space lot ("Project"), As discussed below, the Project is consistent with the applicable provisions of the Town's General Plan and zoning. Prior to entering into a WAC, the Property was designed for residential use at a density higher than the Project's density. With the proposed cancellation of the WAC, the Project is proposed to be developed with single-family residences at a density that is less than or equal to adjacent residential densities. The Project's overall density of 0.57 unit per acre would be consistent with the proposed General Plan's density of 0 to 1 unit per acre and lower than the density that was specified for the site in the 1961 General Plan (prior to establishment of the WAC). 1 4828-5594-1457v1 J-1123008001 The current General Plan Land Use Element designation for the Property is "Agriculture" and the zoning designation is RC (Resource Conservation) in Chapter 29 of the Los Gatos Town Code. Single- family residential dwellings are permitted in the RC zoning district. The Project will require a General Plan Amendment to Hillside Residential and rezoning Hillside Residential (HR-1. However, this will be consistent with the General Plan and zoning designation of adjacent lands. The re -designation of the Property to Hillside Residential would be consistent with Policy LU-1.5 of the General Plan, which states that "Infill projects shall de designed in context with the neighborhood and surrounding zoning with respect to the existing scale and character of surrounding structures, and should blend rather than compete with the established character of the area." Therefore rezoning of the Property would be considered consistent with the Town's General Plan. The Property is surrounded by hillside residential properties and one school property and is considered to be an in -fill development. Adjacent lands to the west are zoned R-1- 10, whereby the minimum lot area is 10,000 sq. ft. Adjacent lands to the southwest, east and north are zoned HR-1 whereby the minimum lot area is 1-5 acres. The Project includes 10 single-family lots and one open space lot. Five lots are in the vicinity of the existing R-1-10 zoned properties and range in size from 0.94 acres (40,912 sq. ft.) to .98 acres (42,648 sq. ft.). The remaining 5 lots range from 1.03 acres (44,698 sq. ft.) to 2.67 (116,327 sq. ft.) that are adjacent to properties, which are zoned HR-1 (minimum lot area is 1 — 5 acres). The Project will include a 3.32 acre open space area. When compared to existing lots in the Project vicinity, the Project lots would fall within the range of lot sizes that surround the Project site with lower lots smaller and upper lots larger, consistent with the lot size pattern that occurs in the immediate Project vicinity. Therefore, the Project would protect the quality of life for surrounding residences and blend with the established character of the area. This price range property has been underserved from 2008 — 2017. The draft 2015 - 2023 Housing element has identified a total of 174 "Above Moderate" income -housing units required to meet the Regional Housing Needs Allocation (RHNA) for this category of housing. This development provides 10 lots towards the 132 homes in this income category that need to be developed during the 2020 General Plan build out period. This project would contribute to the town's proportion of regional housing supply requirements and also be consistent with the development of 1,600 new housing units as anticipated by the 2020 General Plan. D. That the WAC cancellation will not result in discontinuous patterns of urban development. The WAC cancellation for the existing agriculturally designated ground will not result in the removal of adjacent lands from agricultural use to a more urbanized environment. The Project is surrounded by hillside residential properties. Therefore, the Project and the subdivision of the land to hillside residential homes would not encourage removal of nearby lands nor encourage "leap frog" development of urban uses. 2 4828-5594-1457v1 JH\23008001 E. That there is no non -contracted vacant land within three -miles of the subject property — see attached map) of the subject Property which is both available and suitable for the use to which it is proposed the contracted land be put or that development of proximate non -contracted land. The term "suitable" for the proposed use means that the salient features of the proposed use can be served by land not restricted land may be single parcel or may be a combination of contiguous or discontinuous. No proximate non -contract lands that are available and/or suitable for the development of 10 single-family homes and an open space parcel within Three -miles of the property.

Dear Ms. Ramsbottom: The following memo evaluates impacts to regulated habitats (i.e., Waters of the U.S. and State) on both the proposed project and the new Two Access Alternative relying on new information provided by the U.S. Army Corps of Engineers (Corps) as to their jurisdiction on the project site. The primary objective is to incorporate this updated data and analysis into a revised DEIR for the Surrey Farm Estates Project. We have also recommended some additional small changes to better reflect CEQA requirements. The mitigations provided for the bats are somewhat inconsistent with bat biology and timing of various types of surveys. We recommend to replace those mitigations with the following, which ensures that the project would not impact roosting bats nor disturb any active maternity colonies, if present. These mitigations would be consistent with either the proposed project, or the new Two Access Road Project. See the recommended changes below: Mitigation Measure 4.3-4, Protection of Roosting Bats Implementation of these measures would reduce impacts to maternity colonies or roosting bats to a less than significant level. a. A habitat assessment (e.g., visual inspection of trees for sign or evidence of bats) for roosting bats should be conducted prior to any demolition or tree removal. The explicit purpose of these surveys is to identify potentially suitable roosting habitat in the trees and outbuilding onsite. For example, not all trees or structures support potential roosting habitat, and many of these features can be excluded from further consideration by a thorough habitat assessment by a qualified biologist. In addition, a qualified biologist can also employ a lift to visually inspect potential tree cavities to more definitively determine if roosting bats are present. b. For any trees and/or the single outbuilding that are found not to be suitable roosting San Jose: 6840 Via del Oro, Suite 220. San Jose, CA 95119 . Phone: (408) 224-8300.

Bakersfield, CA 93311 habitat or for any tree or outbuilding definitively determined that roosting bats are absent, may be removed with no further action. c. For any trees and/or the single outbuilding that are found to be potentially suitable for roosting bats, different measures are required depending on the season they are to be removed. 1. From March 1- April 15 and August 15-October 15 a two-step removal process should be in place under the direction of a qualified biologist. 2. From October 16-February 28 the two-step removal process should not occur so as to avoid take of overwintering bats. 3. From April 15-August 14, the two-step removal should not occur if a maternity colony is detected or suspected. At this time, nighttime emergence surveys can be conducted to determine if bats are using these trees or the outbuilding. i. If nighttime emergence surveys determine that the tree(s) or outbuilding do not support roosting bats, these can be removed within 2 days of the survey. ii. If on the other hand, nighttime emergence surveys determine that the tree(s) or outbuilding do support a maternity colony, then tree removal or demolition would have to wait until August 15 or until a qualified biologist has determined the maternity colony is no longer present. iii. if nighttime emergence surveys determine that the tree(s) or outbuilding does support roosting bats but does not support a maternity colony, a two-step removal process may commence under the direction of a qualified biologist. IMPACTS TO WATERS OF THE U.S. AND STATE FOR THE PROPOSED PROJECT The DEIR (August 2015) notes that Ross Creek, an intermittent "blue line" stream course, abuts the project site at the southwestern corner. Ross Creek crosses the property via a buried 36" corrugated metal pipe built sometime prior to 1920, and daylights well off the project site, some 650' downstream from Hillbrook School campus. The DEIR identifies an ephemeral drainage swale crossing the site from southwest to northwest. This swale is incised for only short reaches in the upper portions of the site. Apparently, surface flows from the ephemeral drainage swale are picked up at a culvert inlet located near the property's northwestern corner and conveyed via a buried pipe approximately 200 feet to the west, where it empties into the buried culvert associated with Ross Creek. LOA, wetland ecologist Pam Peterson, visited the site with Mr. Keith Hess from the Corps on June 30, 2016 for the explicit purpose of establishing what if any features on site met the definition of Waters of the U.S. and would then be regulated by them. Mr. Hess from the Corps determined that the only area falling under their jurisdiction was a 340 ft2 seasonal wetland in the northwest corner of the site. His wetland verification visit found that the ephemeral drainage swale crossing the site failed to meet the Corps technical definition of Waters of the U.S. Therefore, the only feature regulated by the Corps on the project site is the 340 ft2 seasonal wetland in the northwest corner of the site. The Corps does not consider the ephemeral drainage swale as a Waters of the U.S. and therefore it would not regulate impacts to this feature, nor any other area on site. However, for the purposes of evaluating impacts in the DEIR, it has been assumed that the Regional Water Quality Control Board (RWQCB) under Section 401 of the Clean Water Act and the State Porter Cologne Act, and the California Department of Fish and Wildlife (CDFW) under Fish and Game Code Section 1602, may regulate impacts to this drainage swale. While the RWQCB would also regulate actions that result in discharge or fill of the seasonal wetland in the northwest corner of the site, the California Department of Fish and Wildlife (CDFW) would not as this feature does not have a defined bed and bank as required by Fish and Game Code. The project will avoid impacts to the single small wetland in the northwest corner of the site by constructing the bioswale and detention basin to the southeast of this wetland and by jacking and boring under the wetland at a minimum depth of 30 inches in order to install a 27-inch stormwater line that will connect to an existing underground line that occurs northwest of the wetland, approximately 5 ft. below grade. However, the construction of Streets A and B of the proposed project would impact portions of the ephemeral drainage channel. Impacts to the ephemeral drainage swale from the construction of Street A and B are considered a significant impact to sensitive aquatic habitat for the purpose of this analysis. Impacts to this drainage swale, while not regulated by the Corps, may be regulated the RWQCB and CDFW. The following mitigation is proposed to reduce impacts to the ephemeral drainage swale to a less than significant impact. Mitigation. Avoidance, minimization, and/or compensation measures should be implemented to reduce to the ephemeral drainage swale to a Tess -than -significant level. Mitigation 4.3-7a (Avoidance). The preferred method of mitigation would be avoidance of ail impacts to the ephemeral drainage swale. As the proposed project is designed, it is not possible to avoid all regulated habitats because of the current road design. Thus, full avoidance of the drainage swale is not feasible. Mitigation 4.3-7b (Minimization). Because full avoidance is not possible, actions should be taken to minimize impacts to the ephemeral channel (e.g., potentially waters of the State and under the jurisdiction of both RWQCB and CDFW). Measures taken during construction activities should include placing construction fencing around the riparian habitat and ephemeral channel to be preserved to ensure that construction activities do not inadvertently impact these areas. Mitigation 4.3-7c (Compensation). The Proposed Project would impact some small areas of an ephemeral drainage swale resulting from construction of Streets A and B. Therefore, the project should replace the lost habitat value resulting from this impact through the creation, restoration, and/or enhancement of riparian habitat at the impact location or at one or more appropriate locations near the impacted areas at a minimum of a 1:1 replacement -to -loss ratio and no more than 3:1 for permanent acreage impacts (up to 3 acres created for each acre permanently impacted) as well as reseeding or replanting of vegetation in temporarily disturbed areas according to a site -specific mitigation plan. The final mitigation amounts will be based on actual impacts to be determined during the design phase. If impacts are lessened, then the amount of mitigation should be appropriately reduced. It is expected that all compensation measures can be accommodated onsite within the existing ephemeral channel. An onsite habitat mitigation and monitoring plan (HMMP) would need to be developed with the goal of creating, restoring, and/or enhancing riparian habitats with habitat functions and values greater than or equal to those existing in the impact zone. As such, compensation measures should include, but would not be limited to: • Replacement of all riparian trees (i.e., trees typically associated with riparian woodland habitats) at a replacement -to -removal ratio that conforms with the Town's tree replacement standard. To the maximum extent practicable, removed trees should be replaced with like species or, if such trees are non- native, with species that are known to occur naturally within riparian habitats in the region. These trees should be planted along the ephemeral channel for riparian restoration. Replacement trees should be grown from seeds, acorns, or other planting stock collected from the site or from nearby creeks within the same watershed. • Reseeding or replanting of riparian or vegetation (i.e., a combination of trees, shrubs, and herbaceous vegetation) in temporarily impacted areas and designated habitat restoration areas. At a minimum, the HMMP should include: • The location of all enhancement and/or restoration activities; • Evidence of a suitable water budget to support any created habitats; • Planting specifications; • Site maintenance and management requirements; • Monitoring requirements; • Final success criteria; • Adaptive management procedures; and • A long-term funding mechanism for site management into perpetuity. The monitoring period should be a minimum of five years to ensure that the success criteria have been achieved. Regulatory Framework: Impacts to the ephemeral drainage channel, while not regulated by the Corps, may be regulated by the RWQCB and CDFW. The applicant should therefore, seek authorization from the RWQCB or CDFW for any impacts to the ephemeral drainage channel that cannot be avoided. If the project is able to implement an avoidance strategy, that would vacate the need to obtain permits from either agency. IMPACTS TO WATERS OF THE U.S. AND STATE FOR THE NEW TWO ACCESS ROAD ALTERNATIVE PROJECT The new Two Access Road Alternative Project will avoid all impacts to the seasonal wetland and the ephemeral drainage swale. Therefore, this Alternative vacates the need to obtain permits from the Corps, RWQCB and CDFW as it employs a total avoidance strategy — the preferred option by the agencies. The single small wetland in the northwest corner of the site will be avoided by constructing the bioswale and detention basin to the southeast of this wetland and by jacking and boring under the wetland at a minimum depth of 30 inches in order to install a 27-inch stormwater line that will connect to an existing underground line that occurs northwest of the wetland, approximately 5 ft. below grade. Access roads have in this Alternative been designed specifically to avoid the entire drainage swale, thereby resulting in a total avoidance scenario. Therefore, this Alternative results in a less than significant impact to sensitive aquatic and wetland features as it avoids all impacts to them. Mitigation. As the project avoids impacts to these sensitive habitats no mitigation is warranted. Regulatory Framework: No regulatory permits are required nor applicable for this Alternative as all potential features are being avoided.

This investigation was completed in general accordance with the authorized scope of services outlined in our signed proposal number 32200-B dated September 21, 2012. 2.0 SITE DESCRIPTION The site consists of 16.37 acres of partially wooded, undeveloped former orchard land east of Twin Oaks Drive in Los Gatos. The property has been divided into 11 parcels for a proposed development. A 1939 aerial photograph shows the property as being under orchard cultivation. The property varies in elevation from a high of 945 feet above mean seal level (amsl) on a knoll in the southeast corner of the property to 425 at the western edge of the property. 3.0 BACKGROUND AND PURPOSE AEI was requested to perform shallow soil sampling for chlorinated herbicides, chlorinated pesticides, dioxins/furans, and CA Title 22 metals (Cam 17) to confirm the presence or absence of these chemicals which may have been used on the site during operation of the former orchard. 4.0 INVESTIGATIVE EFFORTS Permits & Clearances No boring permits are required from the Santa Clara County Water District as the soil borings were shallower than 45 feet bgs. The work area was clearly identified with white marking paint and Underground Service Alert North (USAN) was notified in compliance with state law. Health & Safety AEI prepared a site specific Health and Safety Plan (HASP). On November 7, 2012, prior to the start of field activities drilling, a tailgate safety meeting was held at entrance of the work area to review the HASP. Working hazards and emergency procedures were discussed at this meeting, including an explanation of the hazards of the known or suspected chemicals of interest as well as the location and route to the nearest hospital. All site personnel wore modified Level D personal protection equipment. San Francisco (HQ) ' Atlanta Chicago , Costa Mesa 1 Dallas Denver y Los Angeles Miami { New York Phoeni Portland 1 San Jose www.aeiconsultants.com Soil Sampling 4.3.1 Sample Locations The subject property is undeveloped but has been divided into 10 lots to be developed and one lot designated "open space" lot (see Figure 2). Three (3) soil sampling locations (A, B, and C) were selected on each lot and two samples were collected from each location. Surface soil samples were collected from a depth of 0.0 — 0,5 feet below the ground surface (bgs) and were labeled with the letter suffix added as shown below: • SS-1-A, SS-1-B, SS-1-C and SS-2-A, SS-2-B, SS-2-C, etc. Soil samples were also collected from a depth of 1.0 - 1.5 feet bgs and labeled in the same manner as surface samples with the letter suffix added as shown below: • SS-1-D, SS-1-E, SS-1-F and SS-2-D, SS-2-E, SS-2-F, etc. 4.3.2 Sample collection A total of 33 surface (0.0 — 0.5 feet bgs) and 33 deeper (1.0 — 1.5 feet bgs) samples were collected at the site on November 7, 2012. Where accessible, samples were collected using a Geoprobe® 5400 series, truck mounted, direct push, four wheel drive, drilling rig operated by Environmental Control Associates, of Aptos, CA, California C-57 (drilling) License 695970. Samples were collected using a standard 2.25-inch outside diameter by 4-feet long Geoprobe Macro -Core® soil sampler. The Macro -Core® sampler is Tined with an inert plastic sample liner to collect the continuous sediment core. At each accessible location, the sampler was driven to depth of approximately 2.0 feet bgs, to allow recovery of at least 18-inches of soil in the sampler. The sampler was then retrieved, disassembled, and the sample liner containing the core removed and transferred to the onsite AEI geologist. Samples from several locations on steep hillsides that were inaccessible by truck were collected manually using hand tools. A detailed description of the soil cores was not made, however the soil present on the site typically consisted of light brown sandy clayey silt to silty clay with common gravel, pebbles and cobbles of igneous and metamorphic origin. The coarser sediment appears to represents fag deposit derived from the igneous and metamorphic rocks outcropping in the hills to the south of the site. Soil samples were retained from the intervals of 0.0-feet to 0.5-feet bgs and 1.0-feet to 1.5 feet bgs. The shallow soil samples were placed into laboratory supplied 4-ounce (oz) glass jars. Samples from the depth of 1.0-feet bgs were cut from the liner. The ends of each liner were sealed with Teflon® tape and plastic end caps. Each sample was labeled with a unique identifier, project number, time, date and sampler ID. The samples were then entered on a chain of custody record, and placed in a pre -chilled cooler on water ice pending transportation to the laboratory. Samples were transported by the sampler under chain of custody protocol to McCampbell Analytical, Inc. of Pittsburg, California (DHS Certification #1644). The surface soil samples were composited into 3 point composites by the laboratory and analyzed for Organochlorine Pesticides by GC-ECD (8080 Basic Target List) by Method SW8081A; for Chlorinated Herbicides by GC-ECD (Basic Target List) by method SW8151A; for Polychlorinated Dibenzo-p-Dioxins (Dioxins) and Polychlorinated Dibenzofurans (Furans) by method SW8280A; and for CAM/CCR Project No. 313883 December 12, 2012 Page 2 of 6 AEI Consultants 17 Metals (Title 22 Metals) by method SW6020. The deeper soil samples were held for possible analysis following evaluation of the shallow soil samples. Copies of the analytical reports with chain of custody documentation are included in Appendix A. Boring Destruction Following completion of sampling, each soil boring was backfilled filled with compacted native soil. 5.0 FINDINGS The San Francisco Bay Regional Water Quality Control Board (SFB-RWQCB) and California Department of Toxic Substance Control (DISC) have the responsibility for overseeing soil and groundwater cleanups which are managed under a variety of different regulatory programs. The results of this investigation were compared with the RWQCB Environmental Screening Levels (ESLs) for Shallow Soil Screening Levels (<3 meters bgs) for Residential Land Use where groundwater is not a potential drinking water resource and the DTSC California Human Health Screening Levels (CHHSLs) to evaluate the potentialfor impact to the environment and human health. The RWQCB ESLs which are designed primarily for protection of the groundwater are typically used by Santa Clara County Environmental Health (SCCEH) at petroleum based sites while the CHHSLs are typically used to evaluate human health concerns with regard to surface occupancy. 5.1 Soil Sample Analytical Results Pesticides and Herbicides No organochlorine pesticides or chlorinated herbicides were reported at or above laboratory reporting limits. The analytical results for organochlorine pesticides and chlorinated herbicides are summarized on Tables 1 and 2, respectively. Dioxins The least toxic of the dioxins, Octachlorodibenzodioxin (OCDD), was reported in samples SS-1- A,-B,-C and SS-3- A,-B,-C through SS-11 A,-B,-C at concentrations ranging from 10.2 nano - grams per kilogram (ng/kg) (SS-3-A,-B,-C) to 43.4 ng/kg (SS-8-A,-B,-C). OCDD was reported as non detectable in sample SS-2 at a reporting limit of 5.0 ng/kg. The most toxic of the dioxins, 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) was reported as non detectable at a reporting limit of 1.0 ng/kg. All other dioxins were reported as non detectable at their respective reporting limits. Furans No furans were reported at or above laboratory reporting limits. The analytical results for dioxins and furans are summarized on Tables 3. Meta Is Arsenic was reported in all samples at concentrations ranging from 2.3 mg/kg to 7.0 mg/kg. All of these values exceed both the CHHSL of 0.07 mg/kg and RWQCB ESL 0.39 mg/kg. However; back ground levels of arsenic commonly exceed these established guidelines. The 1996 Kearney Foundation report, Background Concentrations of Trace and Major Elements in California Soils, reported arsenic concentrations ranging from 0.6 mg/kg to 11 mg/kg. As a Project No. 313883 December 12, 2012 Page 3 of 6 AEI Consultants consequence of high background levels in the area, Santa Clara County Environmental Health commonly accepts concentrations of arsenic up to 14 mg/kg for residential property. AEI does not consider the reported concentrations of arsenic as significant. Mercury was reported in one sample (SS-4-A) at a concentration of 1.4 mg/kg which is above the ESL of 1.3 mg/kg but below the CHHSL of 18 mg/kg, Re -extraction and analysis of sample SS-4-A reported a concentration of 0.11 mg/kg which gives an average mercury concentration for the lot of 0.76 mg/kg. All other samples reported mercury at concentrations below the ESL and CHHSL. AEI believes all mercury concentrations reported are within the range of normal background for the area and does not consider the reported concentrations of mercury as significant. Nickel was reported in one sample (SS-1-A) at a concentration of 330 mg/kg which is above the ESL of 300 mg/kg but below the CHHSL of 1,600 mg/kg. All other samples reported nickel at concentrations below the ESL and CHHSL. AEI believes all nickel concentrations reported are within the range of normal background and does not consider the reported concentrations of nickel as significant. Vanadium was reported at concentrations ranging of 39 mg/kg to 80 mg/kg. All of these reported concentrations are above the ESL of 16 mg/kg but below the CHHSL of 530 mg/kg. All of the concentrations reported are within the background concentrations reported in the Kearney report. AEI believes all vanadium concentrations reported are within the range of normal background and does not consider the reported concentrations of vanadium as significant. The standard CAM 17 analysis reports total chromium, which includes both chromium III and chromium VI, while the regulatory guidelines have been established for both species of chromium. Typically chromium VI represents a small fraction of the total chromium. Following the common practice, the samples with total chromium concentrations at or above 100 mg/kg, were analyzed for chromium VI. AD these samples reported chromium VI as non -detectable at the laboratory reporting limit of 4.0 mg/kg. AEI believes all chromium concentrations reported are within the range of normal background and does not consider the reported concentrations of chromium as significant. Concentrations of antimony, barium, beryllium, cadmium, cobalt, copper, lead, molybdenum, selenium, silver, thallium, and zinc were reported below both the RWQCB ESL and the DTSC CHHSLs. 6.0 SUMMARY AND CONCLUSIONS No organochlorine pesticides or chlorinated herbicides were reported in the soil samples. All metals except for arsenic, mercury, and vanadium were reported below both the RWQCBs ESLs and CHHSLs. Vanadium and mercury concentrations are within expected background concentrations and below the CHHSLs. Arsenic was reported at concentrations above the RWQCBs ESLs and Project No. 313883 December 12, 2012 Page 4 of 6 AEI Consultants CHHSLs but is within normal background concentrations and below the Santa Clara County Environmental Health's arsenic standard of 14 mg/kg. No furans were reported at or above the laboratory reporting limits and no dioxins except OCCD were reported at or above laboratory reporting limits. No ESL or CHHSL has been established for OCDD. Toxic Equivalency Factors (TEF) for dioxins are listed in Department of Toxic Substances Control (DTSC) Human Health Risk Assessment (HHRA), Note 2 (attached in appendix A). TTCD which has an ESL and CHHSL of 4.5 ng/kg and 4.6 ng/kg, respectively, is the most toxic of the dioxins listed and has a TEF of 1.0. OCDD with a TEF of 0.0003 is the least toxic dioxin on the list. The ratio of TEFs and the TCCD ESL can be used to establish an equivalent ESL for OCDD. 4.5 ng/kg divided by 0.0003 gives an equivalent ESL for OCDD of 15,000 ng/kg. For this reason, the reported concentrations of OCDD are not considered significant. Based on a comparison of the laboratory analytical results and the CHSLs, the subject site will meet the established DISC criteria for residential development. 7.0 REFERENCES G. R. Bradford, A. C.

These goals may be revised in the future, as new scientific information becomes available. HERD ISSUE CONTACT PERSONS: David L. Berry, Ph.D., Senior Toxicologist (916) 255-6625 dberry@dtsc.ca.gov Kimiko Klein, Ph.D., Staff Toxicologist (916) 255-6643 kklein@dtsc.ca.gov DTSC/HERD - Dioxin Remedial Goals Table 1 - Dioxin-TEQ Remedial Goals for Sites in California INTERIM 5/2009 Landscape Scenario ng WHO-TEQ/kg dry matter (ppt) (11) Comments Residential" 50 • 10-6 risk level • 95%© UCL Commercial/Industrial° 200 -1000 • 10° risk level — HI of 1 • 95% UCL Agricultural" <40 • Based on Germany Guideline (6) • Ceiling value a) Based on the California Human Health Screening Level (CHHSL) (3). The CHHSL is adjusted, multiplied by 10, to account for the minimal contribution of soil and dust to the dioxin human body burden as shown in the University of Michigan Dioxin Exposure Study (7, 8). In this study of 946 persons, it was found that less than 0.01% of the variation in serum dioxin concentrations could be attributed to soil and household dust polychlorinated dibenzo-p-dioxins (PCDDs). Similar observations were made in a study of women in West Virginia (4). EPA SW-846 screening level bioanalytical assays (4000 series) may be considered in initial site investigation activities, if this remedial goal is used. b) The suggested residential remedial goal should only be considered if no farming (raising food animals and/or the majority of the food supply of families) is likely to take place at the site. c) A range is proposed from a 10-6 risk, based on the commercial/industrial CHHSL (3) to a concentration based on a Hazard Index of 1 (see below). This risk range should be adequately protective, given the results of the dioxin exposure studies (7, 8, 4). d) Use of this remedial goal as a ceiling value should result in 95% UCL concentrations close to 10 ppt, the guideline for dairy farming in The Netherlands and sensitive uses in Sweden (6). Dioxin remedial goals based on non -cancer effects: A non -cancer remedial goal of 78 ppt is calculated for the residential child based on 1 pg/kg/day (the Minimum Risk Level, MRL, based on neurological effects in monkeys) (1, 10). Therefore, the suggested residential remedial goal of 50 ppt should be protective of non -cancer adverse health effects. The non -cancer commercial/industrial remedial goal is 1,000 ppt, based on the same MRL. Dioxin remedial goals based on the protection of ecological health: This is variable depending on the ecological receptors of concern at the site but may drive a risk -based cleanup. 2 DTSC/HERD - Dioxin Remedial Goals INTERIM 5/2009 Table 2 — 2005 World Health Organization Human Toxic Equivalency Factors for Dioxins and Dioxin -like Compounds WHO-TEQ II Compound WHO 2005 TEF Chlorinated dibenzo-p-dioxins 2,3,7,8-TCDD 1 1,2,3,7,8-PeCDD 1 1,2,3,4,7,8-HxCDD 0.1 1,2,3,6,7,8,-HxCDD 0,1 1,2,3,7,8,9-HxCDD 0.1 1,2,3,4,6,7,8-HpCDD 0.01 OCDD 0.0003 Chlorinated dibenzofurans 2,3,7,8-TCDF 0.1 1,2,3,7,8-PeCDF 0.03 2,3,4,7,8-PeCDF 0.3 1,2,3,4,7,8-HxCDF 0.1 1,2,3,6,7,8-HxCDF 0.1 1,2,3,7,8,9-HxCDF 0.1 2,3,4,6,7,8-HxCDF 0.1 1,2,3,4,6,7 8-HpCDF 0.01 1,2,3,6,7,8,9-HpCDF 0.01 OCDF 0.0003 Non-ortho substituted PCBs PCB 77 0.0001 PCB 81 0.0003 PCB 126 0.1 PCB 169 0.03 mono-ortho substituted PCBs 105 0.00003 114 0,00003 118 0.00003 123 0.00003 156 0,00003 157 0.00003 167 0.00003 189 0.00003 The TEQ concentrations shown in Table 1 are calculated by converting the measured congener concentration in a soil or sediment sample by its TEQ, shown in Table 2, and adding these converted values to get a Dioxin-TEQ concentration for the sample.
