FILE #238-14-TM FROM: Cynthia Richardson, Consultant Planner t~ APPROVED BY: Suzanne Avila, Interim Planning Director 5J\ RECOMMENDATION That the Planning Commission: Forward a recommendation to the City Council for approval of the Tentative Map , including tree removal, based on the findings in Attachment #2 and subject to the Conditions of Approval in Attachment # 1. TENTATIVE MAP REVIEW In order to approve a subdivision, the Planning Commission must determine that the project is consistent with the General Plan, Subdivision and Zoning Regulations, and that none of the findings for denial can be made , as specified in Section 66474 of the State Subdivision Map Act. Staff has prepared findings for approval of the project as shown in Attachment #2 . Comments on the Tentative Map have been received from the Town Geotechnical Consultant, Santa Clara County Environmental Health Department, Santa Clara County Fire Department, PG&E, California Water Service, the Environmental Design Committee, and the Pathways Committee ; and are attached for the Planning Commission 's review (Attachment #3). Neighboring residents and property owners within 500 feet of the site have been notified of the public hearing. BACKGROUND The subject 2 .67 acre property is located at 13651 Burke Road and is bounded on three sides by Burke Road , Old Altos Road and Fremont Road. The existing parcel is currentl y developed with one single famil y residence , a swimming pool, detached garage , sheds and a second unit. Most of the structures were built in the early 1950 's while the main home was built in 1946. All of these structures have been vacant for some time and are in disrepair. The property is co vered with a variety of trees , shrubs and ground covers and according to the Arborist Report , is overgrown. PROJ E CT DESCRIPTION Th e applicant is requesting approval of a two-lot subdi v ision of an ex isting 2.67 (gross) acre parc e l located between Fremont Road , Old Altos Road and Burke Road. The property is sunounded by resid ential properties developed with a mix of one and two ESPRD -Tentative Map December 4, 2014 Page 2 of 11 story dwellings. The site is gently sloping with an average 7.60% slope that descends west to east toward Burke Road.

The Tentative Map includes 160-foot diameter building circles on each lot , showing that each contains a viable building site. Sheet TM-3 of the Tentative Map plan set shows conceptual site design, building footprints, driveways , and drainage installations . This development is conceptual and is intended to show that both lots can be developed to meet Town standards . The applicant submitted a Historical and Architectural Evaluation report prepared by Bonnie Bamburg of Urban Programmers dated June 30, 2014 (Attachment #4). This report reviewed the structures on the property to determine the potential historic or architectural significance of the buildings. It was determined, that the buildings on the property do not have significant historical associations and are not significant to the historical or architectural heritage of the Town of Los Altos Hills . Trees The applicant is requesting removal of twenty four (24) trees with the subdivision. Sixteen (16) of those trees are Heritage Oaks and eight (8) are other species with a trunk diameter of 20 inches or greater. Two Arborist reports have been prepared for the property , one by Kielty Arborist Services dated February 24 , 2014 (Attachment #5) and another by Urban Tree Management dated October 27 , 2014 (Attachment #6). The site is very overgrown with a variety of trees, shrubs and ivy. The applicant would like to clean the site and remove 24 trees as shown on sheet TRE-1 of the plan set. According to the two reports , it is necessary to remove some of the overcrowded trees for the benefit of other trees that have a higher condition rating. Some trees suggested for removal are in poor condition and some have structural problems. In addition , two of the ESPRD -Tentative Map December 4 , 2014 Page 3 of 11 Bay trees on site have tested positive for Sudden Oak Death and should be removed immediately. Staff concurs with the applicant's arborist that the removal of the listed trees would represent good h01iicultural practices. The following table illustrates the trees proposed for removal. Tree Species Size Condition Number (DBH inches) 6 Canary island pine 21 Low Vigor 8 Bay laurel 22.9 Has Sudden Oak Death 9 Canary island pine 28.1 Low vigor 11 Coast live oak 14.1, 13.3 Poor form, decay 12 Coast live oak 15.2 Prone to limb failure, leans south 15 California pepper 36 Poor form, structural faults 20 Coast live oak 16.4 Structural faults 21 Coast live oak 16 Structural faults 22 Coast live oak 31.7 Limb failure 23 Coast live oak 15 .1 Poor vigor 33 Incense cedar 21.8 Very thin, leans southwest 52 Coast live oak 15 Poor form 56 Blue oak 30.9 Fair vigor, tree falling apart 57 Coast live oak 16.3 Leans heavily, remove for density 65 Coast live oak 16.2 Remove for density 66 Coast live oak 24 Remove for density 67 Coast live oak 26.7 Remove for density 69 Deodor cedar 30.1 Structural fault, out of character 72 Douglas fir 30.1 Weak wooded, out of character 91 Coast live oak 12.4 Poor form 95 Coast live oak 28.8 Poor form 98 Coast live oak 13.9, 14.8 Poor form 114 Bay Laurel 5 , 14 Has Sudden Oak Death 116 Coast live oak 24 Poor form , leans east The heritage oaks to be removed are required to be replaced on a 2: 1 ratio with 36 inch box size oak trees. The other species are required to be replaced on a 2: 1 ratio with native 15 gallon trees. All planting shall be reviewed and approved by the Planning Director and must be planted prior to recordation of the Final Map (see Condition #3).

PG&E will provide gas and electric services, Pacific Bell will provide telephone service and Comcast will provide cable service. All utilities are required to be placed underground. Both lots will be tied into the Town 's sanitary sewer system. An encroachment permit must be obtained from the Public Works Department for all work performed within the public right-of-way (see condition #19). Access Driveway access for Lot A will come from Old Altos Road and Lot B from Burke Road . Both Old Altos and Burke Road are publically maintained roads. A 10 foot wide right- of-way easement is required to be granted along all road frontages so that a 30 foot half street can be accomplished. Geotechnical Review The Town 's Geotechnical Consultant, Cotton, Shires and Associates has reviewed the proposed Tentative Map and Geologic Investigation provided by the applicant (Romig Engineers dated July 2014). Cotton, Shires and Associates reported that the project geotechnical consultant has adequately characterized site conditions and recommended appropriate geotechnical design criteria for future residential development on the proposed lots. Cotton, Shires and Associates recommends approval of the Tentative Map with requirements related to future residential development of Lots A and B (see conditions #10 and #11). Drainage All proposed parcels naturally drain to the east over the site and will be required to maintain the existing flow patterns, using surface flow designs whenever possible. Subdivision improvement plans will be required to be submitted with the final map application lot submittal. The applicant 's engineer submitted information pertaining to Adobe Creek from Flood Insurance Rate Map Panel 3 8. A small portion of the proposed right of way easement is located within the Adobe Creek flood area. This small area falls within the proposed road right of way and will not affect the individual parcels . ESPRD -Tentativ e Map December 4 , 2014 Page 5 of 11 COMMITTEE REVIEW Subdivision Committee Conference The Subdivision Committee comprised of Commissioner Tankha, the Interim Planning Director, the Consultant Planner, the City Engineer and the Assistant Engineer convened on October 7 , 2014 to review and discuss the subdivision proposal. Pursuant to Section 9-1.509 of the Los Altos Hills Municipal Code, neighbors within 500 feet of the property were notified of the hearing. One neighbor attended the conference and spoke in favor of the project as well as stating a concern about keeping the pathways safe during construction. Staff also received emails from adjacent neighbors supp01iing the project. The hearing report is attached (Attachment #7). Environmental Design and Protection Committee The Committee commented that according to the Arborist Report, four coast live oaks (numbers 35, 39, 82 and 93) are in good condition and should be retained. The applicant intends to preserve these trees. Sixty nine trees are in fair condition and 42 trees are in poor to bad condition. The Committee requested that as many of the good trees be retained as possible because the trees are one of the parcel 's main attributes. Pathway Committee The Pathway Committee recommended that the subdi vider construct a type IIB path along the Fremont Road right of way, that the roadside path along Burke Road be restored to a ty pe IIB path standard, and that all pathways be restored as needed following construction. ENVIRONMENT AL REVIEW In compliance with the California Environmental Quality Act (CEQA), this project is Categorically Exempt per Section 15315 , Minor Land Divisions , which allows division of property into four or fewer parcels when the division is in conformance with the General Plan and Zoning , no variances or exceptions are required , all services and access to the proposed parcels to local standards are available , the parcel was not involved in a division of a larger parcel within the previous 2 years, and the parcel does not have an average slope greater than 20 percent. CONCLUSIONS Staff has concluded the proposed subdivision is in compliance with the General Plan and Subdivision Ordinance , and would allow dev elopment to occur that meets the provisions of the Zoning and Site Development Ordinances. Staff has prepared positive findings in Attachment #2. ESPRD -Tentative Map December 4 , 2014 Page 6 of 11 ATTACHMENTS 1. Recommended Conditions of Approval 2.

The subdivision as proposed would create two lots: Lot A would be 1.392 acres in size, with a Lot Unit Factor of 1.392; Lot B would be 1.009 acres in size, with a Lot Unit Factor of 1.009. Each parcel would provide a viable building site. In this and all other respects, the lots conform to the Los Altos Hills Subdivision Ordinance. 2. The proposed subdivision would create two lots that would meet the General Plan guidelines for land with an average slope between 10 and 30 percent, and in all other respects will be consistent with the General Plan. 3. Access to the proposed lots will be provided from the existing public roads. Adequate services including water, gas and electric, telephone, fire protection and police protection are available to serve the subdivision as described in the staff report. Future development on the two parcels will require connection of each parcel to the public sanitary sewer system. The parcel is suitable for the proposed density. 4. All lots as proposed on the Tentative Map are physically suitable for the proposed future development. The property is relatively flat, has no creeks or streams and is not located within a special study zone. The Arborist Repo11 prepared for this property recommends removal of several trees that are in poor or declining health and proves to be good horticultural practice. 5. The design of the subdivision and the proposed improvements are not likely to cause serious public health problems. It has been determined that each of the proposed lots contains a suitable building site, and that the proposed density is consistent with the General Plan . 6. The Town Engineer has reviewed the project and has determined that the design of the subdivision and the improvements will not conflict with easements, acquired by the public at large, for access through or use of the property within the proposed subdivision. ~ COTTON, SHIRES AND ASSOCIATES, INC. ~ CONSULTING ENGINEERS AND GEOLOGISTS TO: SUBJECT: RE: Suzanne Avila Acting Planning Director TOWN OF LOS ALTOS HILLS 26379 Fremont Road Los Altos Hills, California 94022 Geotechnical Peer Review EESPRD LLC, Two Lot Subdivision #238-14-TM 13651 Burke Road ATTACHMENT 3 Se ptember 19, 2014 L5204 RECEIVED SEP 2 2 2014 TOWN OF LOS ALTOS HILLS At your request, we have completed a geotechnical peer review of the proposed subdivision and Tentative Map Application using: • Geotechnical Investigation (report) prepared b y Romig Engineers, Inc., date d July 18, 2014; · Tentative Map Exhibits (4 sheets, 20-cscale) prepared by Lea & Braze Engineering, Inc., dated June 30, 2014; and • Topographic Survey (2 sheets, 20-scale) prepare d by Lea & Braze Engineering, Inc., dated November 11, 2011.

The top of the ridge is relatively flat. The slopes of the eastern and western flanks are both gentle, however, the eastern flank (15-percent) is slightly steeper than the western flank (11-perecent). The proposed subdivision creates a property line on the eastern edge of the ridge top leaving the majority of the ridge top and western flank on Parcel A and the eastern flank on Parcel B. Drainage is generally characterized by sheetflow to the east and west. Existing improvements at the site include a residence, guest house, garage and pool. Based on the Town Geologic Map and data from the referenced geotechnical report, the majority of Parcel A is underlain at shallow depths by sandstone bedrock of the Santa Clara Formation. Parcel B is also mapped as being underlain, at depth, by Santa Clara Formation bedrock, however, the referenced report indicates that at least 8.5 feet of residual clayey soils overlie the bedrock in this location. The San Andreas Fault is located 4.6 miles to the southwest of the property and a trace of the Monta Vista Fault is mapped 1 mile to the southwest of the property. CONCLUSIONS AND RECOMMENDED ACTION The lots created by the proposed subdivision are constrained by potentially expansive earth materials and strong seismic ground shaking. Parcel B is further constrained by an undetermined potential for flooding of Adobe Creek. We w1derstand that potential flooding issues will be addressed to the satisfaction of the Town Engineer. The Project Geotechnical Consultant has completed a site investiga tion that is in general conformance with prevailing standards of geotechnical practice. The Consultant has concluded that the proposed subdivision is feasible from a geotechnical perspective, a .d W'~ conn~: ~·:it.1-i this conclusion . Consequently, \ e reccmunend geotechnical approval of the proposed Tentative Map application. In addition, the Consultant has provided recommended geotechnical design criteria for development of the subdivided lots . The Consultant recommends mat tmmdations for proposed basements and continuous spread footings for at grade portions of shuctures. Recommendations for a pier foundation are also provided specifying a minimum of 8 foot of embedment below the bottom of the associated grade beams. The Consultant's recommendations assume that development of Parcel A will include a residence with a full basement and that development of Parcel B will include a residence with a partial basement. We do not anticipate objections to site development or building pennits on Parcel A, assuming the final development plans include a COTTON, SHIRES AND ASSOCIATES, INC. Suzanne Avila Page3 September 19, 2014 L5204 residence with a full basement. If future development plans for Parcel A do not include a full basement, then modified development plans should be reviewed from a geotechnical perspective. Regarding the future residential development layout on Parcel B, we understand that the main residence may include a partial basement with an adjacent at- grade floor level. Completed borings in the vicinity of the house site did not determine the depth to bedrock, and we are concerned that a mat basement fom1dation combined with shallow spread footings (for at-grade portions of the residence) may result in differential bearing conditions and possibly adverse differential settlement across the house. If shallow footings are used for at-grade portions of the structure, then adjoining basement walls should be designed for anticipated surcharge loads. We recommend that updated geotechnical design recommendations be prepared for final proposed structures on Parcel B and that supporting documentation be reviewed by the Town Geotechnical Consultant. In summary, we recommend geotechnical approval of the subject Tentative Map with the following conditions attached to future residential development permit applications for each lot: 1. Parcel A-If future development plans do not include a full basement beneath the residence, then updated geotechnical design recommendations should be prepared and final site development permit documentation submitted to the Town for review by the Town Geotechnical Consultant prior to issuance of permits for site grading or construction. 2. Parcel B -The Project Gcotechnical Consultant should review the above noted comments regarding Parcel B and update geotechnical design recommendations as warranted to address final site development plans . The final site development lay out plan and supporting geotechnical documentation should be submitted to the Town for review by the Town Geotechnical Consultant prior to issua.."'1.c e of p ermits for sit e grading or construction. LIMITATIONS This geotechnical peer review has been performed to provide technical advice to assist the Town with its discretionary permit decisions. Our services have been limited to review of the documents previously identified, and a visual review of the property.

Only four (4) trees, all coast live oaks, numbers 35,39 , 82 and 93, are noted as being in good condition and these should be retained at all costs. 2. Sixty nine (69) trees are in fair condition a nd forty two ( 42) are in poor to bad condition. Nevertheless, as many as possible of all the trees should be retained, because the trees as a whole are one of the main attributes of the site . 3. The lot division line should be as simple as possible with the aim of minimizing tree felling. The tree condition rating used is taken from the covering letter of Kielty Arborist Services . Pat Ley (Chair) Property decisions Pathway Committee Regular Meeting, August 25, 2014 I believe you already have the minutes for the Stirling subdivision. I would add one detail -on Lot 5, where the pathway easement joins the conservation easement, we agreed the two become the same at the point where the conservation easement becomes greater than 30 feet. a. 26644 Purissima Rd. -Repair existing IIB path on Purissima at the end of the construction period, with special attention to repairing the corner where the path meets the driveway. At present this corner just drops off over some decorative rocks. b . 25520 Deerfield Dr. -(at the corner of Burke Road and Deerfield) If no easement exists, grant easement for IIB path along Burke, within the road right of way. Because the lots appear to be substandard, no pathway path is required on the Deerfield frontage. WC moved that the Town require the developer of 25520 Deerfield Drive build a IIB path in the road right-of-way along the Burke frontage and to dedicate a pathway easement if necessary. EG seconded and the vote was unanimously in favor. c. 25608 Deerfield -Although an off-road path exits from the end of Deerfield , the lots on this street appear to be substandard (less than one acre) and the street has little traffic. The PWC "bubble map " shows the pathway in the Deerfield road right-of-way. SW moved that the Town require the developers of 25608 Deerfield Dri v e to pay a pathway in-lieu fee. WC seconded and the vote was unanimously in favor. d. 12345 Briones Way -WC moved that the Town require the owners of 12345 Briones Way to pay a pathway in-lieu fee. EG seconded and the vote was unanimously in favor. e. 26355 Esperanza Drive -Be sure there are underlying pathway easements for roadside path along Esperanza and Ascension. Re-construct IIB path beside Esperanza and construct IIB path on Ascension frontage. WC moved that the Town require the developer if 26355 Esperanza Drive 1) to build a IIB pathway in the road right-of-way using a retaining wall and/or additional easement if necessary; and 2) to build a IIB roadside path along the Ascension frontage. ND seconded and the vote was unanimously in favor. f. 13651 Burke Rd. -WC moved that the Town require the subdivider of 13651 Burke Road to 1) construct a IIB path in the Fremont Rd. right-of-way and to dedicate additional easement along Fremont if necessary ; and 2) to require the owners to restor e the roadside path along Burke Road to IIB standards after construction is completed and h av e staff confirm the Town holds a pathway easement on the Burke frontage .

EXECUTIVE SUMMARY The property known as 13651 Burke Road, Los Altos Hills has been sold and the owner has a proposed plan to subdivide the property. This may include an interest to remodel the house and ancillary buildings or remove them to redevelop the site. Because the buildings are over 50 years old there is the potential that they are significant historic resources. This study and evaluation was commissioned to understand the potential for the property to be considered a valuable historic resource in the Town of Los altos Hills or to be eligible for listing in the California Register of Historic Resources. This report considers the history and architectural values of the buildings on the parcel. Los Altos Hills, as Lead Agency, must comply with the California Environmental Quality Act (CEQA) as it pertains to historic resources. The Town may consider the information contained in this report to evaluate the proposed project according to CEQA Guidelines and historic preservation policies used by the Town. The following report describes the research into the historic associations with the owners, the architecture, construction methods and materials, which were considered and evaluated as part of the process leading to the conclusion that the main house and ancillary buildings are not significant to the history and architectural heritage of the Town of Los Altos Hills. Research was conducted in the repositories of the Los Altos Historical Museum; San Jose City Library; United States Census Records, City Directories, Santa Clara County Assessor's Records and Official Records of the County, as well as the Building Permit files maintained by the County . Site visits and photographs were also used in preparing the report and evaluation. The property has been the home, residential garden, experimental garden, and orchard of the George D. Cummings family, and their son George D. Cummings Jr . and his family . The families were involved in many interesting activities but none are considered significant to the history of Los Altos Hills, the region or the State. This report evaluated the historic and architectural significance of the main house, a barn and a caretaker's cottage on the parcel other ancillary buildings, sheds and landscaping were also considered. Findings: Based upon the research and site visits, it is concluded that the buildings on the property do not have significant historical associations and are not significant to the historical or architectural heritage of the Town of Los Altos Hills . When compared to the criteria of the California Register of Historic Resources, the property is found not eligible for listing due to a lack of significant historical associations with people or events and because it is not a representation of a significant architectural or artistic style . 5 (Jrban frogra mmers \ 1. 2.

INTRODUCTION The following report provides a brief historical background of the Town of Los Alto Hill to set the context for the background of the parcel at 13651 Burke Road (APN 175-25-004). Standard methodology for collecting the contextual information was employed in collecting the information used in this study. 2. 1. HISTORICAL CONTEXT-LOS ALTOS HILLS AREA The history of Los Altos Hills has been a series of eras, each well defined by how and who was resident and how the land was used. The following is a brief summary of the distinct eras to establish the context by which to evaluate the historical and architectural values of the property at 13561 Burke Road. The first era -1776 This era is documented to be that of the first inhabitants, the Oholone people. Part ofthe Coastonan language group they lived in small villages throughout the Santa Clara Valley. The inhabitation by the Oholne was an existence of gathering acorns, berries, and other wild plants, hunting and fishing . Their legacy is found the sites of habitation and burial that have been identified in archeological studies. The Oholne people did not survive the second phase, 1776- 1822. The Spanish Exploration and Mission era 1770-1822 This span of time was one of exploration by the Spanish seeking to settle the vast new works for the King of Spain. The first European discovery is attributed to Gaspar de Portola and the expedition of 1776, who passed through the area in search of the mouth of the Bay of San Francisco. This was followed by the development of the California Missions, Santa Clara and San Francisco by Franciscan Fathers under Fr. Juniper Serra whose charge was to convert the native population to Catholicism. During this era the Presidios of San Francisco and Monterey were established as was the first civil settlement a Pueblo at San Jose. Land grants were also given to settle the land. The primary economy of this era was based in cattle. Tragically the Spanish brought with them diseases unknown to the native Oholne population and together with trying to impose an unfamiliar life style, the two took a horrific toll. The Oholne were all by extinct by 1850. The loss of the Oholne villages was the lasting legacy of this era in the Los Altos Hills. The Mexican era 1822-1850. At the conclusion of the Mexican War of Independence the governing rule of California changed from Spain through Spanish Governors located in Mexico to Mexican rule carried out by Governors sent from Mexico. Among the many changes this brought a desire to allow trade beyond what the Spanish controlled, secularization of the Missions, and encouraged settlement by awarding many more land grants. During this era the two Ranchos-large land grants -that encompass Los Altos Hills were given. Rancho La Purissima Concepcion, 4,436 acres was 7 Urban f rogrammers I granted to Native Americans Jose Gorgonio and his son Jose Ramon in 1840 and sold to Juana Briones de Miranda in 1844 for the sum of $300; and Rancho San Antonio, 4,438 acres granted to Juan Prado Mesa. Adobe Creek served as the boundary line of the two ranchos . This period is known for its predominance of lumbering and trading and later for agriculture. The primary industry of these Ranchos remained cattle raising (meat and hides) although logging and timber exports were initiated and the value of the "red wood" and oak was realized by the early European or American settlers who arrived by ship or overland trails. American Period 1848-1900 The next 52 years brought great population and economic growth to California and to the Santa Clara Valley. The discovery of gold at Sutter's Fort and the ensuing Gold Rush of 1848-1860 brought many Americans and Europeans to California, some found gold others formed businesses or began farming. It was also the era when, in 1850 California was granted statehood. By 1852, stage coach service to San Francisco through the Peninsula to San Jose was fairly regular allowing both goods and people to travel the distance in less than half a day. In this era, the verdant hills provided the natural resources for the lumber industry to develop contributing to population (residential}, and local economic growth. Five years after statehood, Martin Murphy arrived in Santa Clara County and purchased 3,000 acres of Rancho La Purissima Concepcion from Juana Birones. Soon the Murphy family land holdings spread throughout Santa Clara County including the founding the City of Sunnyvale. While there were many changes in the economy of California the single event that brought the greatest change to the Santa Clara Valley was the 1869 arrival of the continental railroad connecting Santa Clara Valley to the rest of the Nation. This is also the era when agriculture, orchards and farms became the leading economic industry of the County. In the area of Los Altos Hills, agriculture in the form of fruit orchards filled the land that had been logged of the oak and redwood trees. Subdivision, Mansions and Mass Transit define the era 1900-1945. For the north county area, the development of a train station at Los Altos brought renewed interest in the hills to the west. Agriculture was the prime industry and events in the Fremont District, the area that became Los Altos, had an impact on growth in the adjoining hills. The area was developing a downtown-commercial canter along Main Street encouraged Paul Shoup and the Los Altos Land Company. At the insistence of Paul Shoup, President of Southern Pacific Railroad, a train station was developed in Los Altos in 1913. The Los Altos train station provided access to San Francisco and San Jose, a service that was crucial for commuters and potential residents of Los Altos and Los Altos Hills. The improved transportation access and infrastructure provided by the Southern Pacific Railroad predictably encouraged the sale of property including the lots improved by the Los Altos Land Company. Paul Shoup is credited as "The Father of Los Altos" for the development of the 100 acre Winchester tract that became the heart of the City and the commercial center for the adjacent hill community. Residential architecture of the era followed the popular styles, many influenced by the Columbia exposition in Chicago 1893. The "City Beautiful" movement brought expressions of Revival styles, even copies of European estate homes. Homes were designed by leading architects from the Bay 8 (Jrban frogrammers I Area including Charles McKenzie, John H. Powe r s (Morgan Manor), and Ernest Coxhead as well as landscape architect Emerson Knight. Incorporation and Permanent Population Growth 1945-2014 As with most incorporations, the residents of Los Altos Hills sought local control over the development of property. The overriding goals were to maintain the rural atmosphe r e and r esidential use of the community. Incorporated in 1958, the Town has maintained the original atmosphere although it has experienced some of the most luxurious residential development in the Bay Area. Some of the amenities that have been provided include the Count ry Club, a private club on the former estate of Dr . Thomas Shumante that prese rves some ofthe structures, and the Los Altos Golf and Country Club-that started in the early 1920s but had a resurgence in the 1950s-60. A lso the Los Altos Hills Heritage House Museum was designated and opened to the public. However, the largest single entity (other than r esidences) is Foothill College, one of the outstanding community colleges in California. The award winning design-a turning point in campus architecture -was by Ernest Kump, Jr. and landscape architect Hideo Sasaki. The campus opened in September 1958. Residential styles dur i ng this period include the Bay Area Traditions 1 & 2, Mid-century modern and California Ranch, Rust ic, and in recent years variations on the post-modern -historicist styles. Currently Los Altos Hills is recognized as one of the wealthiest communities in the nation and is home to many of the leaders of industry from Silicon Valley and San Francisco. 2.2 Background of the property located at13561 Burke Road, Los Altos Hills After the turn of the Century (1900), the subject property was owned by George D. Cummings who was born in 1856, in Canada and immigrated to the United States in 1871 becoming a naturalized citizen.1 The 1916 Santa Clara County Voter Roll lists George D. Cummings as a cacti orchardist in Los Altos. Alice Cummings is listed as a housekeeper . About 1925, Cummings worked to develop a thornless cacti that could be an economical feed for cattle. Unfortunately the experiment did not work out as the cacti continued to grow spines . 2 The Cumming's marriage ended in divorce with Alice continuing to live on the Burke Road property with their three children, and George is just listed as living in the Fremont Dist r ict (Los Altos) until he died in 1936. He is buried in Alta Mesa Memorial Park . Their son George D. Cummings Jr. born in 1911 lived with his mother on the Burk Road property while growing up and attending 2 years of college. The Voter Rolls for 1934 list both Alice and George D (student) living at Box 84, Los Altos. George was actually a student at Notre Dame University during this period. 3 Shortly thereafter George Jr . married as is shown in the 1940 U.S. Census which lists George D. and Jane Cummings (Dorothy Jane Riccomi) residing at 125 Castilian Way Los Altos . George is listed with the occupation of Accountant for a tannery (Legalle Tannery). The family moved to Hillsborough and during the marriage had four children, Joan, George D. Cummings Ill. Ba no and Mary. In 1946 the family engaged in building a new house to replace the older one on the subject property. In addition to the house, a linear building, the property included a swimming 1 U.S. Cens us 19 00 2 Los A lt os Town Crier, Nove mb er 2 , 2 00 4, Do na ld Mc Donad :F irst Rad io St at ion an d cactus far m . 3 No tre Dame M agaz ine , Notre Dame Co ll ege, 201 4 9 Urba n f rogra mm e rs I pool, barn, greenhouse, caretaker's cabin, stable and landscaped terraces. The barn was turned into a garage, and the caretaker's cabin was enlarged. George and Jane raised their family on the property while George maintained his work in accountancy working with trusts and other financial arrangements . Jane's death preceded George who passed away at age 99 on October 23, 2010. The site reveals that fruit trees were planted in an orchard pattern, as well as some berries and several specimen trees. For the most part these are not tended and most have been removed . Though a sale, approved by a court appointed referee, the family members who inherited the subject property sold it to Energy Efficient Sustainable Personal Residence Development, LLC on January 9, 2014.

It is in an area where over the last 15-20 years, many of the irregular shaped parcels of land have been realigned and redeveloped with new houses and tailored landscaping, often concealed from the street by perimeter bushes and trees. The area is wooded with native second growth trees and native bushes in addition to those intentionally planted and the large landscaped yards. The subject parcel, shielded from the road by mature trees and bushes is on a slope putting the house above Burke Road. 3.2 BUILDINGS AND LANDSCAPING The property that is the subject of this study and evaluation is shown as APN175-25-004 and was recorded with Santa Clara County as Map M page 33 Block 39, Lotl, Subdivision Map 4 Town of Los Altos Hills. It is bounded on three sides by public roads, Burke Road (considered the front of the property}, Old Los Altos Road and Road. The irregular shaped parcel is 2.6 acres on a sloping hill side. The primary house was constructed in 1946, however a barn and caretaker's cabin on the property appear to be 25 or more years older. The main house is a wood frame, linear, rectangular shaped building that conforms to the terrain and is accessed by steps in the center of the front fa~ade leading to the recessed front porch. The entry door is flanked by walls constructed in "used" brick the material that outlines the base of the building and appears to be the foundation for the addition, and is used for a planter box on the front fa~ade. A temporary ramp has been installed to access the entry. On the south side a projecting section has a large square, multi-pane window with a planting box at the bottom that is centered in the wall. In the recess created by this projection is a ground level planter that is formed with used brick. The remainder of the fa~ade includes two square windows with multi -pane glazing matching the one on the other side of the entry. On the far south, behind the body of the building is an addition c. 1970, which creates a new room on the house by creating a pitched roof section that is extended with glass panels forming a rounded wall. This glass panels are set between vertical wood posts with a separate roof structure over this element . The original walls of the house are horizontal board with a red stain and this is continued in the additions. The roof is a low pitch that is uniform the length of the building with eaves that overhang showing exposed rafter tails. The north fa~ade maintains the same theme as the front and rest of the building using horizontal flush board siding. A second entry is accessed by steps on this end. The rear fa~ade (west) is notable for the broad pergola that covers a patio and the entire length of the fa~ade. On this fa~ade the building has banks of windows that extend the length of the building and doorways, but follows the theme without additional ornamentation. 11 Urban r rogrammers I Overall the building is identified as a Mid-century, Second Bay Region Tradition, bringing the outside into the interior through large expanses of glass often covered with a screen or pergola. The design is really a transitional and vernacular design. The design is pleasing, giving a nod to a lodge style, in the linear form, but is not a significant or highly artistic design or use of materials. The next building in order of size is the square barn/garage that sits to the north of the house and is oriented on an angle. This building appears to be c. 1930s although there have been modifications and even a section that appears to be an addition. A lean-to open shed is on the south side. Notable about the building are the large doors which are double wide and slide on a rail, with window panels at the top, unusually artistic for a utilitarian barn or pre 1950 garage. It appears that an addition was added to the side of the building. This has more mundane double doors with diagonal boards and diamond cut-out windows in each door. The pitched roof extends with eaves that have exposed rafter tails. Covering the roof is sheet metal. A remodeled and enlarged cabin type building set away from the main house is rustic in design and construction. This is also in poor condition with obvious deterioration from lack of maintenance and both water and insect intrusions. The building is set above the grade and accessed by wood stairs. The building has multiple additions and alterations that appear to more than double the original size. It has a pitched roofs over most of the additions, however a shed roof covers one section, and there is no ornamentation, design detail or even a attempt of coordinate the additions. This building has had several additions, note by the change in roof structures and materials . The building has so many alterations that it has lost integrity. At the north end of the house a children's play house is constructed to match the main house. This small wood structure has a pitched roof and single door at the end. The last building on the property is a wood frame and glass panel greenhouse c. 1950 with a pitched roof and operable panels. The building is not large enough for a commercial operation and does not appear to be old enough to have been used by George D. Cummings for his experiments with cacti. West of the house is the swimming pool terrace. This appears to have been constructed some 10 years after the main house, c 1955. The rectangular pool and surrounding deck are constructed of concrete. This area shows a lack of recent maintenance and is gives evidence of more extensive planting. Set away from the residential complex is a small stable and a second support building. The stable appears to be c. 1950 or later, and is a typical design with a pitched roof that extends to provide a shaded tie up space. The second is of plywood and is more of a shed. Landscaping on the site includes rock lined walkways that surround the main house and extend in to the swimming pool, green house and to the barn/garage . The planting appears to be mature with few annual or other high maintenance plants . Trees include a few orchard verities 12 Urban F rogrammers I in addition to the mature native redwood and a variety of other species. Away from the residential complex the property and paddock are lined with split rail fences. It does not appear, and no evidence was found, that a landscape architect planned the site prior to putting in the swimming pool. The complex presents the impression of a Mid-century country home with ancillary features for swimming, horses and gardening . The number of trees and bushes indicates the work of George D. Cummings and his enjoyment of plants. Many appear to have been distressed over the past few years. It does not display significant architecture in any of the buildings and collectively the the only architectural theme is found on the main house-horizontal board siding and used brick. Otherwise there is not a cohesive theme to the enclave .

EVALUATION OF HISTORICAL AND ARCHITECTURAL SIGNIFICANCE For purposes of this report the criteria used to evaluate the property is that of the California Register of Historic Resources . The Los Altos General within the Conservation Element, Sections 338 and 339 and 340 and Goal 10 sets forth statements, policies and programs for the public good to preserve the community:S heritage. The following is copied from the Los Altos General Plan 2009 (italics). 338. The preservation of historic sites and structures helps maintain and enhance the unique character of Los Altos Hills. Some of the sites listed below have already been recognized for their historic importance and are registered state historic landmarks. However, the historic importance of all sites listed below should be preserved in a manner most appropriate to the individual site. 339. The Town should explore the possibility of having existing historic structures designated as state historical landmarks. Historic sites without structures may have to be purchased if the Town determines that historic significance warrants preservation in a natural state. In any case, the historic significance of all sites should be evaluated prior to development. 19 (Jrban f rogrammers I At minimum, if the site is found to be of some historic significance, provision for historic commemoration should be required as part of development. In addition, the Town should establish a program for the evaluation and preservation of historical sites. 340. While it is the intent to preserve identified resources for the benefit of the Town, it is recognized that there will be circumstances where it will not always be possible to achieve preservation . Such determinations cannot always be made in advance and therefore prudent decisions must be made when individual resources are before the Town for action. These policies are carried forth in the following goal. Goal 10 Encourage both public and private efforts to preserve and enhance historic resources. Policy 10.1 Preserve, protect and enhance the historic resources of the planning area because they are unique and valuable assets for the community and region. Policy 10.2 Promote community awareness of local history and historic resources for the education, pleasure and welfare of the people of the Town. Program 10.1 Continue to develop a comprehensive inventory and map of historically significant sites and structures. Review Appendix A at least every five years and update the inventory as appropriate. Consider adding the following sites and structures: Heritage House, Finn House, Westwind Community Barn, Packard House, Hidden Villa, Ginzton House, Lois Crozier Hogle House, Hills Country Club Water Tower, Jensen House and Barn, Eshner House, and Stegner House on South Fork. However, the document does not include criteria for evaluating historic resources. Therefore the criteria of the California Register of Historic Resources, as the threshold for identifying significant historic resources under CEQA is used for this evaluation . 4.1 Relevant Historical Context: The area of Santa Clara County that became Los Altos Hills was developed in the mid 1800's through the turn of the century in response to the natural resources that were harvested, lumber, fur, water and agriculture. This activity brought awareness of the attractiveness of the area and the lure of a resort stay or of a country home to those primarily from the San Francisco metropolitan area who spent the summer months surrounded by fog. The acquisition by Martin Murphy began the transition to American ownership and the agricultural economy that followed. Within the first quarter of the new century (1900), tracts of land were subdivided for "second" homes with sales and construction marking a new era in the area . The years from 1900 -1941 is the period when the division of land for second homes or agricultural estates defines this historical context in the Fremont District that includes Los Altos Hills. Beginning after WWII the subdivisions began to attract more permanent residents to the area and development pressures for even smaller parcels caused the community to consider incorporation. Wishing to retain the "lifestyle" of a rural residential village, the citizens of Los Altos Hills began the process of incorporation which took until January 27, 1956, to complete. 20 (jrban f rogrammers I The parcel at 13651 Burke Road was part of subdivided land at the turn of the century and was occupied with buildings that are no longer extant. The buildings that are considered in this study and evaluation begin with the This occurs at the beginning of the historical period identified as the Incorporation and Permanent Population Growth 1945-2014, with the house evaluated under the theme of residential architecture. The association with the subdivision was part of a broad pattern of early century land divisions that marked an increase in development within the Fremont District in the latter part of the nineteenth century. However, this lot and the subsequent buildings were only part of the pattern of subdivisions, and are not defining or individually significant to that broad pattern . George D. Cummings appears to have been an inventor and general entrepreneur dabbling in several areas of potential industries. It does not appear that his work resulted in a significant advance in any of the areas. George D. Cummings Jr. {II), is the developer of the main house on the property . Like his father he seems to have had wide ranging interests although his business followed the accounting path that began his career. Research did not identify events or activities that were significant in the development or history of Los Altos Hills. 4.2 Evaluation-California Register of Historic Resources The criteria for listing historical resources in the California Register of Cultural Resources are similar to those of the National Register of Historic Places, but have been modified {broadened) for state use in order to include a range of historical resources which better reflect the history of California. An historical resource must be retain architectural integrity to communicate the reason for its significance at the local, state or national level under one or more of the following four criteria: Criterion 1. It is associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. The property was divided as one of the early subdivisions in the Fremont District, however the current parcel is not the same acreage as the original subdivision for Lot# 1 and the property is not significantly associated with broad patterns that have made a significant contribution to local, regional or state history or cultural heritage. The property does not meet the definition of criterion 1. Criterion 2. It is associated with the lives of persons important to local, California, or national history The history of the property described that it was home to a succession of men George E. Cummings, his son, and grandson who appear to have broad interests, but the property does not show a direct and significant association with persons important to the history of Los Altos Hills, Santa Clara County, the State of California, or nation. The property does not meet criterion 2. Criteria 3. It embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master or possesses high artistic values~ The property includes a house and barn/garage that are the primary buildings on the property. The house is designed in a vernacular style, a transition of Mid-century and Second Bay Region Tradition. 21 (Jrban f rogrammers [ However, the result is not distinctive for the period, or region nor does it exhibit a unique method of construction. The house and barn are not eligible for listing under criterion 3. Criteria 4 . It has yielded, or is likely to yield, information important to the prehistory or history of the local area, California, or the nations. During the agricultural use, excavation and development of the property, the native soils have been disturbed. It is unlikely that significant information important to prehistory or history would be found on this site. The site does not appear eligible for listing under Criterion 4 . Should Native American remains or artifacts be found during any construction, State law will be followed. 5.0 CEQA REVIEW The California Environmental Quality Act (CEQA) is the principal statute mandating environmental assessment of projects in California, and as such. it is part of the Public Resources Code, sections 2100 et.seq. The purpose of CEQA is to evaluate whether a proposed project may have an adverse impact on the environment and, if so, if that effect can be reduced or eliminated by pursuing an alternative course of action or through mitigations. CEQA requires the Lead Agency to determine if a project will have a significant impact on the state's historic resources. Historic Resources are defined as any resource eligible or listed in the California Register of Historic Resources or are locally significant and have been designated by a local preservation ordinance or that have been identified in a local historical resources inventory may be eligible for listing in the California Register of Historic Resources and are presumed eligible for purposes of CEQA unless a preponderance of evidence indicates otherwise, (PRC s. 5024.1.14 CCR S.4850) However, a resource does not need to have been identified previously to be considered significant under CEQA. Lead Agencies have the responsibility to evaluate potential resources against the California Register Criteria prior to making a finding as to a proposed project's impact to historical resources . (PRC s 21084 .1, 14CCR s 15064 .5(3)) Further, section 15064.S(b)(l) and (2) of the California Environmental Quality Act (CEQA) forbids the "demolition or the destruction, relocation, or alteration activities that would impair the significance of a historic resource that results in a substantial adverse change. Substantial adverse change includes demolition, destruction, relocation, or alteration such that the significance of an historical resource would be impaired (PRC s . 5020.l(q). When the Lead Agency determines that the proposed project does not include a historic resource, then, demolition, relocation, alteration or destruction of a building (that is not eligible for listing in the California Register of Historical Resources) does not constitute a significant adverse change under the CEQA Guidelines. Finding/Recommendation : The property listed at 13651 Burke Road in Los Altos Hills does not meet the criteria for listing in the California Register of Historic Resources and is not a significant historic resources under CEQA . 22 Urban f rogrammers I A project has been proposed to subdivide the property. If or when subdivision of the property is approved if is likely that the existing buildings would not be retained and that new residential buildings would be developed on the subdivided lots. The alteration or removal of buildings that are not eligible for listing in the California Register of Historic Resources does not require mitigation for the elements of historic preservation found in the CEQA Guidelines. 6.0 SOURCES CONSULTED: 6.1 Repositories used and persons consulted include: Santa Clara County Building and Planning Dept.

Box 6187 San Mateo, CA 94403 650-515-9783 Site: 13651 Burke, Los Altos Hills, CA Dear Mr. Badros, ATTACHMENT 5 RECEIVED AUG 4 2014 TOWN OF LOS ALTOS HILLS At your request on Friday, February 19 , 2014 , I visited the above site for the purpose of inspecting and commenting on the trees. New construction is planned for this site and your concerns as to the future health and safety of the trees has prompted this visit. Method: The trees on site were located on a map provided by you. Each tree was given an identification number. This number was printed on a round metal tag and nailed to the trees near ground level. The trees were then measured for diameter at 54 inches above ground level (DBH or diameter at breast height). Each tree was given a condition rating for form and vitality. The trees' condition rating is based on 50 percent vitality and 50 percent form , using the following scale. 1 -29 Very Poor 30 -49 Poor 50 -69 Fair 70 -89 Good 90 -100 Excellent The height of each tree was estimated and the spread was paced off. Comments and recommendations are included. Summary: The trees on site are a mix of native oaks and bays and several species of imported trees. The lot is heavily wooded with many of the trees growing with poor form as they compete for available light. The suppressed growth is common for trees growing in crowded landscapes. Removal of the imported trees and the bay trees will help to re-establish the proper tree spacing. The bay laurels are the alternate host of sudden oak death and their removal is the most effective method to reduce the spread of the disease. The deodar #69 and the olives on site contribute to 13651 Burke/2/24/14 (2) the property and their retention should be considered. Removal of the oaks with a condition rating under 50 should also be considered. Several native oaks will be removed from the site to facilitate the construction. Some of the removed oaks will be removed to allow other over-crowded trees to thrive. Trees #22 and #24 are an example of this. If one of the two trees were removed the remaining tree would thrive with the reduced competition. The percentage of oaks on this site to be removed will be low and will not have a negative effect on the surrounding environment. The Los Altos Hills Fire District has removed the dead trees and the eucalyptus trees on site. The removal of these trees are directly related to fire danger. The following tree protection plan will help preserve the trees to be retained. Tree Protection Plan: Tree protection zones should be installed and maintained throughout the entire length of the project. Fencing for tree protection should be 6' tall, orange plastic fencing supported by metal stakes pounded into the ground. The location for the protective fencing should be as close to the dripline of desired trees as possible, still allowing room for construction to safely continue . No equipment or materials shall be stored or cleaned inside the protection zones . Areas outside protection fence, but still beneath the tree 's driplines , where foot traffic is expected to be heavy , should be mulched with 4-6" of chipper chips covered with plywood. The spreading of chips will help to reduce compaction and improve soil structure . Four foot tall orange plastic fencing supported by metal stakes will suffice for tree protection in the areas away from the buildings . Demolition and Staging Prior to the start of the demolition process, all tree protection measures must be in place. An inspection prior to the start of the demolition is required. A pre-demolition meeting with the site arborist will be required . All vehicles must remain on paved surfaces if possible. Existing pavement should remain and should be used for staging. If vehicles are to stray from paved surfaces , 4 to 6 inches of chips shall be spread and plywood laid over the mulch layer. This type of landscape buffer will help reduce compaction of desired trees. Parking will not be allowed off the paved surfaces. The removal of foundation materials , when inside the driplines of protected trees , should be carried out with care. Hand excavation may be required in areas of heavy rooting. Exposed or damaged roots should be repaired and covered with native soil. Tree protection fencing may need to be moved after the demolition. The site arborist should be notified and the relocated fence should be inspected. Root Cutting Any roots to be cut shall be monitored and documented . Large roots (over 2" diameter) or large masses of roots to be cut must be inspected by the site arborist. The site arborist , at this time , may recommend irrigation or fertilization of the root zone. All root s needing to be cut should be cut clean with a s aw or lopper. Roots to be left exposed for a period of time should be covered with layers of burlap and kept moist. The over dig for the foundation should be reduced a much as possible when roots are encountered. The site arborist will be on site for all excavation when within the dripline of the trees listed above. 13651 Burke/2/24/14 (3) Trenching Trenching for in-igation, drainage, electrical or any other reason shall be done by hand when inside the dripline of a protected tree. Hand digging and the careful placement of pipes below or besides protected roots will significantly reduce root loss , thus reducing trauma to the tree. All trenches shall be backfilled with native materials and compacted to near its original level , as soon as possible. Trenches to be left open for a period of time (24 hours), will require the covering of all exposed roots with burlap and be kept moist. The trenches will also need to be covered with plywood to help protect the exposed roots . The information included in this report is believed to be true and based on sound arboricultural principles and practices. Sincerely, Kevin R.

At that time he rated the Condition of the trees. As a benchmark, all trees rated 44 and below were in unquestionably Poor Condition and their immediate removal is obvious. It was therefore my assignment to review all Protected Trees (Oaks with 12"+ trunk diameters and all non-Oaks with 20"+ diameters with a Condition rating of 45+) and make further comments as to their status. Summary This is a 2. 7 acre lot that has been abandoned for a long time. The trees and structures are in Poor Condition with some exceptions in some of the Oaks on site. The new owners have a lot line adjustment and development plan that is site sensitive to retaining the majority of the Good Oaks on site. Many more trees will be planted as part of their overall development plans. At this time there are many small and some Protected trees that should be removed to get this property ready for development and up to a standard befitting the new plans. The new owners are land stewards with sensitivity to the site and the environment that I rarely see. Removal of the designated trees will make way for sensible development and the planting of the next generation of trees. There are 18 trees that fall into the scope of my report. In several instances images of the trees are used to further illustrate the point. The Trees Sudden Oak Death (SOD-Phytophthora ramorum) is a threat to Coast Live Oaks (Quercus agrifolia) across the Bay Area. Bay Trees (Umbellularia californica) are a host to SOD. The disease is hosted on the Bay trees and falls onto the Oaks, and kills them. Our company has tested several Bay trees on client's properties and found positive results for SOD. We highly recommend that all Bay trees be removed in order to protect the Oaks from contracting SOD. This includes tree #8 (CRSS). Oak #114 has Sudden Oak Death on site. Tree #6 Canary Island Pine (Condition Rating [CR] of 45) and #9 Canary Island Pine (CR 55) are both thin canopied trees with Low Vigor. These trees are so thin and that if they were to have ll Pa g e t650+321 +0202 I f408+399+8063 I po box 971 los gatos ca 95031 I urban tree monogement.co m controctors license # 7 55989 • certified orborist WC ISA # 623 I certified tree risk osse uor # 1399 their dead wood removal removed', they would be unacceptable all together. Their removal would be a benefit to the property. Oak #12 (CR 50) leans South and has a co~dominant stem. Co-dominant stems are trees with poorly attached limbs with narrow angles of attachment. Co-dominant stems are highly prone to limb failures . Pepper Tree #15 (CR 55) is also a co-dominant stemmed tree (see image to right). This is the only Pepper on site and it should be expected to fail at some time in the next 5 -10 years due to its species and the structural fault of the co-dominant limbs. Oaks #20 (CR SO) & #21 (CR 45) both have major structural issues. Tree #20 has thin foliage (indicating overall tree stress) and a large dead limb. Tree #21 has a dead limb in the center of the tree, co-dominant stems and a Poor overall form. Oak #22 (CR 55 -image to right) has two co-dominant stems, suffered a limb failure. The removal of Oak #22 will remove the hazards of the co- dominant limbs in this tree. Incense Cedar #33 (CR 55) is very thin and need to be removed. Blue Oak #56 (CR 55 -image to right) has lost some major limbs since Mr. Kielty wrote his report. This tree is in the process of falling apart and needs to be removed. 21 Page Oak #57 (CR SO) leans heavily as with several Oaks in this area. The density of the trees in this area has the trees reaching for light in a manner that is not sustainable for long-term stability. Removal of some select t rees will allow for the proper growth of the remaining Oaks. Oaks #65 (CR SS), #66 (CRSS) & # 67 (CR 45) also fall into this category. Deodar Cedar #69 (CR 65) has three co-dominant leaders at 35'. I would give this tree a condition rating much lower than Mr. Kielty due to the severity of the structural fault in this tree. This tree is also somewhat out of character for the property and detracts from the Native Oak Woodland. I recommend removal of this tree. Douglas Fir #72 (CR SS) is a tree that should be up i n the steep hills o n the Coastal Range and not on the flats of Los Altos Hills. This tree species is weak wooded and should be removed to enhance the Oak Woodland . Oak #95 (CR 50) has a thin canopy and no chance of recovery. This t r ee is very close to the building, which probably caused the initial stress in the tree. This tree needs removal and replacement at this time. Oak #116 (CR 45) leans so severely that t here is no way this tree will be able to hold itself up or develop a normal/safe structure. I recommend this tree be removed and replaced. Please contact me should you have any further quest ions. Respectfully, ;'! / I I . -1 .. ·• . r_.-·// I . ,. I ! I • . ·' t / r . __,,,~,. ; I : l~ .,_,. I • v Michael P.

During the Tentative Map process the Subdivision Committee prepares recommendations to the Plam1ing Commission. The recommendations include input from neighbors , standing committees, utility companies, Town Geologist, City Engineer and the Fire Department. (LAHMC 9-1.509 Subdivision Committee conference) On August 4, 2014 , the Town received a Tentative Parcel Map application for the property at 13651 Burke Road. A Subdivision Committee Conference was held on September 24, 2014 . The owner's Engineer was present along with , one neighbors, one Planning Commissioner and a representative from the Environmental Design and Protection Committee. The one neighbor who attended the meeting lives on Fremont Road and has concerns about the pathways being safe during construction. She indicated that she and her children use the pathway system on a daily basis and would like it to be safe . She also indicated her support for the project. Staff requested additional information from the applicant concerning lot configuration and additional information for clarification of the Tentative Parcel Map. The Town Geologist recommends: 1. That the project Geotechnical Consultant provide additional information at the time of site development of each parcel. The Environmental Design and Protection Committee recommends: 1. Four (4) coast live oaks, numbers 35 , 39 , 82 and 93 , are noted as being in good condition and these should be retained at all costs. E ESPRD Tentative Parcel Map Subdivision Committee Conference Memo October 7, 2014 Page 2 2. Sixty nin e (69) trees are in fair condition and forty two ( 42) are in poor to bad condition. Nevertheless , as many as possible of all the trees should be retained , because the trees as a whole are one of the main attributes of the site. 3. The lot division line should be as simple as possible with the aim of minimizing tree remo val. The Pathway Committee recommends: 1. Recommend construction of a type II2B path along Fremont Road and to restore the roadside path along Burke Road to a type II2B standard after construction is completed . 2. The Committee also wanted to confirm the Town holds a pathway easement on the Burke road frontage . Complete information can be reviewed in the subdivision file at Town Hall. x33JM6HjgPRP5vA39vL5mHmFNwKFvZl6b97ZmosxmRh6aV1EUXJ4f0VwLUHPWr. ..

Your diligence and out reach to us is commendable. We are both particularly thrilled that you are going to be placing your house at pretty much the same spot as the Cummings. We also love your ideas for screening & fencing around the tennis court. Nice job! After reviewing the maps you showed us for your lot subdivision, our first preference would be option B. Either of the options A or B are okay as they would ensure that we would always have only one neighbor along our lot line. We have been spoiled having all that open land next door. We always new this day would come and we are supportive of you subdividing the property into two lots. We would just rather have one neighbor as opposed to two. You have done a really good job of placing the structures on the site so as to keep the rural feeling of the lot intact. Sorry, but we aren't able to attend tomorrow's meeting . Let us know how it goes. If you need us to write a letter or attend the next meeting, let us know. Thanks for keeping us apprised of your progress.

Please let us introduce ourselves and our project: Ginny, Greg, Jax (2 years old) and Alexis (9 months old). We moved to Los Altos in 2009 {just the two of us back then), and soon realized that this was where we wanted to build our dream and raise a family. After four years searching for a lot, in November 2013 we finally found the perfect place that was walking distance to Town and large and flat enough for a tennis court. (Greg is an avid player since age 7, and Ginny has quickly gotten good in recent years ... we hope the kids will find the same love for tennis!) The tree-laden lot reminds us of our childhood homes in rural Wicomico County, Maryland and outside of Atlanta. For the closing of the property, we created Energy-Efficient Sustainable Personal Residence Development company (EESPRD--an unfortunately austere sounding abbreviation) to ensure everyone we work with understands our goals for our new home: a modern, passive, solar-powered residence that we can grow old together in, and that we, our neighbors, and the Town can be proud of. From the start, we worked with our architect Matthew Mosey and arborist Kevin Kielty to work with the land to find the best possible location for the tennis court, the home, and other structures on the lot. Kevin's detailed report of the over one hundred mature trees on the densely-forested property was instrumental in guiding our selection of the south setback as the location of the tennis court: although not the optimal north-south orientation for playability that we hoped for, that location preserves the most trees including all trees in good health and the vast majority of all Oaks, minimizes grading, and nestles the court deep on the lot to avoid disrupting the rural character of the Town. We worked with the immediate neighbors , John and Cathi Lerch, to coordinate a screening plan and are grateful for their support of the tennis court and our plans overall. We've met and have the support of other neighbors too --it's truly been a pleasure to be so warmly greeted by everyone! RECEIVED OCT 0 7 2014 lOWN OF LOS ALTOS HILLS We then considered a subdivision of the lot because we have no need for the 16,200sf MFA and over 40,000sf MDA that the 2.7 acre property allows. Working with the Town's planning department staff, we propose a fully-conforming property line that uses the natural subtle ridge as a separator to create two beautiful lots: a 1.5 acre western lot on the modest plateau and a 1.2 acre eastern lot. For easements on all three surrounding roads for expanded right-of-ways, we'll dedicate about 12,000sf of gross lot (over~ acre) and end up with net lot sizes that are roughly 1.4 acres and just over 1 acre. When permitted, we will be deconstructing and donating the existing older structures on the lot and are developing plans for parcel A as our primary residence. We show the anticipated development areas for that (including the main residence, a tennis court, swimming pool, pool house, and partially detached garage) on the tentative map. We've engaged Peter Rumsey as our energy and sustainability consultant --we were impressed with his thoughtful attention to the environment with his work on the Packard Foundation Building in Los Altos . The plans for Parcel Bare less far along, but we show a rough footprint for a residence and a guest house on that lot and are hoping to coax friends or family to move in next door (we intend to maintain ownership of that lot indefinitely as well). We 're excited to be a new part of the Los Altos Hills community and cannot wait to get started improving these two lots to make them wonderful additions to the Town! We've put a great deal of thought into our subdivision proposal and our intended improvements already and are happy to answer any questions. Yours, hrr/0JU / Ginny and Greg Badros badros@gmail.com, 415.738-8336
