Call to Order and Approval of Minutes A. Roll Call. KG called the meeting to order at 9:05 am. B. Acceptance of Meeting Minutes. PB moved to accept with minor amendments the minutes from the meeting of June 14, 2018. RC seconded and the vote was unanimously in favor (PB, GC, RC, NC, KG, SW, WW). JS not yet present. C. Announcements. i. SCVWD Program to Map Arundo in County. KG will send an email to OSC members describing the SCVWD effort to map and eventually eradicate Arundo donax (Giant reed) infestations in the county. This invasive plant degrades riparian and fish habitat, spreads downstream easily, and is a flood and fire hazard. OSC members are encouraged to report infestations at the program web site. ii. Request for proposals. KL will send email about program seeking proposals to reduce burnable materials. She proposed a program to inspect buildings in LAH post notices indicating status. 2. Planning A. OSC Site Reviews and Recommendations for Development Projects. i. 13581 Wildcrest (Lands of Sutaria and Capozzola; APN 175-36-021; #18-0013). Reason for OSC review is construction of a new residence. OSC reviewed this property at the June 14. 2018 OSC meeting with a recommendation to modify the existing OSE (CR 26-00; Attachment A) to match the location of the existing retaining wall as shown on the figure on page 2 of the 6/14/18 Draft OSC Property Review and to make a special note to protect the oaks close to the house (#6, 8, 10, 11) during construction. The project architect is present today to request a reduction in the area of the OSE to accommodate the storm water runoff dissipater, which was located outside the original existing OSE, but will be within the modified OSE recommended by OSC last month. The architect also is concerned about temporary construction activities that will have to take place within the OSE because it is close to the house. OSC reviewed the plans and discussed options. It is OSC understanding that drainage improvements, including storm water run off dissipators, are allowed in OSEs. LAH Engineer, Jeremy Koch, confirmed that these are allowed in OSEs. NC moved that the OSC 1) reaffirm the recommendation for the location of the OSE made at the June 2018 OSC meeting and to send a note to staff to remind them that drainage improvements, including storm water run off dissipators are allowed in OSEs; and 2) confirm OSC understanding that construction equipment will be needed to be used during construction within the eastern portion of the OSE that is close to the new house. WW seconded and the vote was unanimously in favor (PB, RC, NC, KG, WW, SW). ii. 27261 Sherlock Road (Lands of Sherlock; APN 182-30-013; SD18-0023). Reason for OSC review is construction of a two-story garage. The lot is on top of a ridge and slopes down steeply on two sides. Sherlock Road (private) runs through the parcel. Two small oaks will be removed. Two existing open space easements dedicated in 1996 (CR 107-96; Attachment B and C) are on the lower portions of the parcel on both sides of the ridge (i.e., on the steep northern and southern portions of the lot). RC moved that the OSC recommend the Town request the developer to show the existing open space easements on the plans and to identify the oaks that will be removed. KG seconded and the vote was unanimously in favor (PB, RC, NC, KG, WW, SW). B. Fence Permit Reviews. Not discussed. OSC FINAL_Minutes18-0712.docx 2 C.

New Business A. Guest speaker Ted Sayre, Town geologist. Mr. Sayre discussed the LAH Hazard Map and Geologic Map and other geology topics relevant to development. KG distributed a handout with policies from the LAH General plan that pertain to geology issues (Attachment D). B. Election of OSC Chairperson and Co-Chair. SW nominated KG to be re-elected as chair. WW seconded and the vote was unanimously in favor (PB, RC, NC, KG, JS, WW, SW). KG nominated RC to serve as Co-Chair. NC seconded and the vote was unanimously in favor (PB, RC, NC, KG, JS, WW, SW). 4. Continuing Business A. Town weed management. OSC discussed plans for stinkwort spraying. In June, a subcommittee (PB, RC, KG, SW) was formed to work with LAH Public Works Director, Allen Chen. OSC again discussed methods to address “private infestations (e.g., contacting residents with large infestations; using Fire District weed abatement program) and methods to map infestations and follow them year-to-year (ideally a Town-hosted GIS system). SW moved that OSC send a memo to Carl Cahill and Allen Chen describing rationale and plan for spraying stinkwort, and soliciting their input, with the expectation that the Town will spray again this year. OSC will also contact them about how the Town can address infestations on private land. JS seconded and vote was unanimously in favor (PB, RC, NC, KG, JS, WW, SW). OSC members selected areas of Town to map stinkwort infestations for spraying. Members were also encouraged to report stinkwort infestation along I-280 to the Caltrans website. (KG will send link.) GC: Moody Road (and all cul-de-sacs off it) from Page Mill to FHC KL: Canyon Road; WW: Bullis School area; J Zarcone: Central Drive. PB: SE part of Town (streets bordered by El Monte, Magdalena, Summerhill, and I-280; Magdalena south of freeway; Ravensbury, Camino Hermosa, Quarry subdivision) KG: Altamont and Elena (and all cul-de-sacs) RC: Moody to Old Snakey? SW: NW part of Town (Liddicoat loop, Paseo del Robles loop, Page Mill cul-de-sacs from Middle and Fork north; Saddle Mtn area). B. Grassroots Ecology update. Byrne Brigade workdays continue through first week of August with focus on removal of purple star thistle, teasel, and YST. Natives planted in the flood plain are doing well. Kristen Williams would like to make a short presentation to OSC in September or October. C. Updates from other Town meetings. Council approved the tentative map for the Top Elegant Investment subdivision on June 21, 2018. 5. Open Discussion A. OSC review of development projects. OSC discussed how staff decides whether or not to direct projects to OSC for review. It appears not all projects that may meet criteria for OSEs are sent. B. Future Guest speakers. KG suggested inviting Planning Director Suzanne Avila and the two new Planners to future OSC meetings to facilitate communication and clarify criteria for OSC review. 6.

OSC Site Review 13581 Wildcrest.docx 8/18/18 1 To: Los Altos Hills Planning Department From: Open Space Committee Date: June 14, 2018 Property address: 13581 Wildcrest Drive Date of Site Visit: May 31, 2018 Lands of Sutaria & Capozzola APN 175-36-021 Town Planner Suzanne Availa Project Number SD18-0013 Reason for review (check one) ü New Residence Second Unit Addition/Major Remodel Fence Permit OSC RECOMMENDATION FOR THIS PROPERTY Date of OSC review: June 14, 2018 Voting of review: Unanimously in favor (RC, WW, NC, SW, JS, RC, PB, KG) Absent (GC) Final OSC recommendation: The property is a steep (~40%) 1.15 net acre lot that has had significant cut & fill & retaining wall construction. The plan proposes to cut and export ~3400 cy of soil and redo retaining walls. A tributary to Robelda Creek traverses the southern boundary. An open space easement exists on the lower southern third of the property but with a loopy boundary that does not correspond with existing cut/filled contours. There are swales and open spaces easements on west and east boundaries of the property covering steep slopes and established oak woodlands. Two significant oaks trees (#7, #9) are planned for removal. Swales near western and southern boundary drains to Robleda Creek. Recommendations: 1. Redraw the Open Space Easement to match the existing fill contours at the border of lower retaining wall and oak canopy; approximately between elevation lines 340 & 350. 2. Riparian setback 25 feet from southern border. 3. Remove chain link fence at western boundary. The fence appears to be connected to this site but is just outside the property boundary. 4. How will proposed drainage system traverse lower retaining wall? Will this wall be removed? 5. Concerns about eastern building abutting edge of OSE and under oak canopy – how can oaks be protected?

Conservation Goal 3: Maintain and enhance the integrity of wildlife habitat. Conservation Program 3.3: Assess the potential for development patterns to fragment and isolate significant wildlife habitats. Conservation Section 315: Planning for natural movement of wildlife can help avoid, minimize and compensate for serious negative impacts on wildlife and humans. Areas that link wildlife habitat have become vital because native animals such as deer, fox, bobcat, and coyote are prevented by roads, fences, homes and other development from moving freely as they once did. Municipal Code 10-1.507 (d) Prohibited Fences, Walls, Gates, and Column Types. The following fences are prohibited: (1) Chain-link or cyclone fences, including any fence with bare lengths of wire stretched between metal poles, with the exception of dark green, black, or brown vinyl- coated chain-linked fences with matching vinyl-coated cross bars and caps.

charter is to make open space easement recommendations based on the General Plan to properties under development. Below are some of the General Plan policies that pertain to geology and open space easements. LOS ALTOS HILLS GENERAL PLAN GEOLOGY REFERENCES: Safety Element Policy 1.1 Open space easements, zoning and other land use regulations shall be used to limit and, in some cases, prohibit development in areas of unstable terrain, active fault traces, water channels, flood plains, excessively steep slopes and other areas determined to be hazardous to public welfare and safety. Safety Element Policy 1.2 Unstable terrain, active fault traceso water channels, flood plains, excessively steep slopes and other areas determined hazardous to public welfare and safety shall not be developed unless unobtrusive corrective measures can assure public safety. Safety Element Policy 2,2 Locate development so as to avoid geologic hazardso including slope instability, to the maximum extent feasible. Safety Element Policy 3.1 Leave natural channels and flood plains in a natural state, unencumbered by development to the maximum extent feasible. Exceptions shall be made only in situations where it is essential to protect established property values or for public safety. Land Use Element Policy 2.5 Steep slopes, canyons and ravines generally in excess of 30% slope, as well as natural swales and drainage channels, and geologic hazard areas within areas designated for residential development shall be left undisturbed and preserved in their natural condition to the maximum extent feasible. Land Use Element Policy 2.6 Limits on the development of inpividual residential lots shall be determined based on evaluation of such factors as natural vegetbtion, topographic characteristicsn soils and geology. Open Space Element Policy 1.2: Protect and maintain those areas ltecessary to the integrity of natural resources and processes, with special emphasis on, but not limited to, the groundwater recharge and drainage system, open spaces vital for wildlife habitat, open spaces suitable for agriculture, and other areas of major or unique ecological significance. Conservation Element Policy 5.1 Keep or restore major drainage courses in their natural condition insofar as possible because of their importance in supplying major vegetation, land forms and wildlife habitat, and storm drainage. Conservation Element Program 5.2 In the planning, environmental impact review, and completion of all land development or land alteration projects, direct particular attention toward the protection of the natural water system. Conservation Element Policy 11.5 Ensure that development projects are designed to conserve the natural slope, preserve existing native vegetation, limit invasive species, and conserve natural drainage channels and swales.
