ITEM 3.3

TOWN OF LOS ALTOS HILLS December 3, 2015 Staff Report to the Planning Commission

SUBJECT: SITE DEVELOPMENT PERMIT FOR A NEW TWO STORY RESIDENCE WITH A BASEMENT AND A SWIMMING POOL; LANDS OF PICHA!; 25857 WESTWIND WAY; FILE #-338-ZP-SD-GD

FROM: Suzanne Avila, Planning Director SA

RECOMMENDATION: That the Planning Commission:

Approve the requested Site Development Permit, subject to the recommended conditions of approval in Attachment 1.

BACKGROUND

The subject property is a 3 .1 7 acre parcel located on the southwest comer of W estwind Way and La Paloma Road. The property was created as part of a 7-lot subdivision approved by the Town in 1980 (Tract 6928, recorded April 1981). Two of the lots were later combined to form one larger lot (Parcel Map 544, recorded March 1985). Vehicular access from Westwind Way is prohibited by the recorded maps. The property is currently developed with a residence, hardscape and pool. Access is from a shared driveway off Westwind Way that serves four lots. Surrounding properties are all developed with single family homes.

There is an existing pathway along the W estwind Way and La Paloma Road frontages. A portion of the path is located outside of the recorded pathway easement. The easement will be reconfigured so it includes the entire pathway. Other easements on the property include an ingressegress easement that includes a portion of the shared driveway, and a public utility easement along La Paloma Road.

The project complies with Fast Track criteria, however, all of the proposed floor area is within a single building that will collectively be larger than 10,000 square feet, therefore the project is governed by the Estate Home Ordinance (total proposed floor area is 10,557 square feet). Estate Homes are required to be reviewed by the Planning Commission.

CODE REQUIREMENTS

Pursuant to Section 10-1.508 (Estate Homes Ordinance) of the Municipal Code, this application for a new residence has been forwarded to the Planning Commission for review. The Zoning and Site Development Ordinances are used to evaluate proposed projects including floor and development area limitations, grading, drainage, height, setbacks, visibility and parking requirements.

The applicant is requesting approval of a Site Development Permit to construct a 9, 716 square foot two story residence with 3,651 square foot basement and an attached 840 square foot three-car garage. The total proposed floor area is 10,557 square feet exclusive of the basement which is exempt since it is entirely below ground. The new residence has been sited in the same location as the existing house.

The main floor of the residence has 6,4 73 square feet of living space consisting of a laundry room, guest bedroom, offices, 2Yi baths, kitchen, family room, dining room, living room and gym. This level also includes the 841 square foot garage.

The main level has 3,244 square feet of living space with a master bedroom and bath, two additional bedrooms, two baths and a family room.

The basement is 3,651 square feet and includes a mechanical room, storage, wine cellar, laundry room and nanny's quarters.

As required by the Estate Home Ordinance, the minimum setbacks are 44 feet from the front property line and 3 3 feet from the sides and rear property lines. The applicant has further increased three of the setbacks as follows:

Front Rear West Side East Side

62 feet 100 feet 33 feet 179 feet

The maximum building height on a vertical plane is 24 feet 6 inches and the maximum overall height of the building from the lowest point to the highest point is 31 feet. Proposed exterior materials consist of cement plaster and wood siding with limestone and wood trim. Building elevations are shown on sheets SD 9 and SDlO of the development plans, Attachment 5. The


contemporary design presents a low profile, and the variety of exterior materials including cement plaster, wood, limestone and glass will provide interest and help break up the massing of the home. Story poles have been installed to aid the Commission in reviewing the proposed project.

Green Building Ordinance

The project is required to comply with the Green Building Ordinance. The new residence is designed to achieve 131 points under Build it Green's GreenPoint Rated program where a minimum of 50 points is required for certification. Condition #15 requires the applicant to submit documentation verifying that the new residence has been constructed to meet green building certification standards prior to final inspection.

Driveway & Parking

The existing driveway will be removed and a new driveway will be constructed off the shared driveway, closer to Westwind Way. Nonconforming parking spaces off the private driveway will be removed.

Pursuant to Section 10-1.601 of the Zoning Ordinance, a total of four on-site parking spaces are required. The applicant is proposing a three car garage that is part of the main level of the house (see sheet SD4 of the development plans) and three uncovered spaces for a total of six parking spaces.

Trees & Landscaping

An arborist report was submitted that provides information on the size, health and condition of 63 trees on the property (see Attachment 3). The applicant is proposing to remove the redwoods and orchard trees as well as three olives and two mayten trees. There are 10 oaks on the site that will be retained (five are heritage oaks). A conceptual landscape plan has been provided (see sheet Ll.O of the development plans).

A landscape plan will be required after the new residence has been framed. Any landscaping required for screening or erosion control will be required to be installed, and a maintenance deposit to ensure viability of plantings will be collected, prior to final inspection and issuance of an occupancy pennit for the new residence. As required by the Estate Home Ordinance, the landscape screening plan will be forwarded to the Planning Commission for review (see condition #2).

Outdoor Lighting

The applicant is proposing shielded and down directed lights on the exterior of the residence (see sheet SD13 of the development plans for proposed locations and lighting details). Condition #10 requires outdoor lighting fixtures to be in compliance with the Town's Outdoor Lighting Policy.


Drainage

The drainage system for the new development includes storm drain piping and area drains around the residence, with an earthen swale along the front of the residence. Pursuant to Section 10-2.503 of the Municipal Code (Drainage Facilities Standards), the Engineering Department has reviewed and determined that the proposed drainage design complies with Town requirements. The Engineering Department will review and approve the final drainage plan prior to acceptance of plans for building plan check. Final "as-built" grading and drainage will be inspected by the Engineering Department and any deficiencies will be required to be corrected prior to final inspection.

Grading

Proposed grading incudes 2,350 cubic yards of cut and 800 cubic yards of fill, with export of 1,550 cubic yards. Most of the earthwork is excavation for the basement. Cut and fill depths are in compliance with the Town's Grading Policy.

Fire Department Review

The Santa Clara County Fire Department has reviewed the plans and is requiring a sprinkler system throughout all portions of the new residence and garage. The property is located within the Wildland Urban Interface Fire Area and will be required to comply with the provisions of Chapter 7A of the California Building Code. Fire Department requirements are included in the conditions of approval in Attachment 1.

Geotechnical Review

The Town's Geotechnical Consultant, Cotton, Shires & Associates, reviewed the plans and geotechnical report and determined that the project geotechnical consultant's recommendations are in confonnance with prevailing professional standards. The Town Geotechnical Consultant recommends that one of two proposed stormwater energy dissipaters be relocated to reduce potential erosion and slope instability. The project consultant will review the construction and drainage plans to ensure that their recommendations have been incorporated. The project consultant is also required to submit a final letter verifying that they have done any necessary site observation and inspections, and that the as-built conditions are consistent with their recommendations (see condition #17).

Committee Review

The Environmental Design and Protection Committee commented that no irrigation should be placed within five feet of the pathway, and that the 48-inch oak located near the house should be protected. The applicant intends to retain the large oak.

The Pathways Committee recommended that the existing pathway be restored at the end of construction, and that water bars be installed along W estwind to prevent erosion. In addition, the Committee asked that the pathway easement be modified to align with the existing pathway.


Condition #28 requires dedication of a new pathway easement. Condition #29 requires the pathway to be restored at the end of construction, prior to occupancy of the new residence.

Neighbor Comments

The applicant and project architect met with surrounding neighbors and shared the plans for the new residence. One neighbor that did not meet with the owners or architect contacted staff and expressed concern that the proposed residence will affect a portion of their view. Four neighbors have submitted letters of support for the proposed project (see Attachment 4).

CEQASTATUS

The project is categorically exempt from CEQA pursuant to Sections 15303(a) which allows for the construction of one single-family residence and Section 15303(e) which allows for accessory structures inclusive of swimming pools.

TOWN OF LOS ALTOS HILLS

As requesteclon Tuesday, July 14, 2015, I visited the above site to inspect and comment on the trees. A new home and landscape is being designed for this site and your concern as to the future health and safety of the trees has prompted this visit.

Method: The significant trees on this site were located on a map provided by you. Each tree was given an identification number. This number was inscribed on a metal foil tag and nailed to the trees at eye level. The trees were then measured for diameter at 54 inches above ground level (DBH or diameter at bi;east height). Each tree was assigned a condition rating from 1 to 100 for form and vitality using the following scale;

1 - 29 Very Poor 30 "." . 49 .Poor 50 - 69 Fair 70 89 Good 90 - 100 Excellent

The height of t:<ach tree was'.c;stimated and the spread was paced off. Lastly, a comments section is provided.

Oak tree#28

(7)

Summary: The trees on site are a mix of native oaks and several species of imported trees. There are 12 native oak speCies on site with a diameter over 8 inches. All of these native oak trees are planned to be retained as they are assets to the property. Valley oak tree #28 has a diameter of 44.6 inches. This tree is a magnificent tree, with a great deal of maintenance applied to the tree in the past. There is multiple cables installed in the canopy of the tree, to ensure the trees safety, as well as a constant maintenance trimming done in the past to lighten the heavy lateral limbs. This tree is the main focal point of the property and will be well protected during construction activities. The new proposed building deck and overhang will be located 43 feet away from valley oak #28. The construction will not affect the oak as the work being done is of considerable distance away from the tree. Any roots found here would be insignificant in size and to the trees health. This tree is expected to have no impacts from construction activities.

There are 28 redwood trees on the property. These trees are not native to this section of Los Altos hills. Redwood trees around town have been showing symptoms of drought stress, although a majority of these redwoods seem to be in good health, a few of them have begun to show minor symptoms of drought stress. These symptoms may be reversed by deep water fertilizing the trees and putting them on an irrigation schedule. A few of these redwood trees will need to be removed to facilitate the new driveway and parking area for the new proposed home.

The north east side of the property is on a slope. On this slope is what appears to be an old apricot orchard. All of the fruit trees on this orchard are over mature and are in decline. A majority of them are decaying at a rapid rate. There are no existing plans at this time for this area.

All of the trees in the courtyard where the existing pool is located will be removed to facilitate construction. These are all small imported trees under 10 inches in diameter. There are 2 nice Japanese maples in the pool area that can be moved and saved if needed or wanted.

There are flowering plum trees that line the existing driveway. All of these trees are in decline as a majority of them have an abundance of decay. These tree have a short life span and will need to be replaced soon. A few trees located close to the existing home are not expected to survive demolition of the home and will need to be removed. None of these trees are of heritage size. The following tree protection plan will help to insure the future health of the retained trees.

25857 Westwind Way /8/4/15 (8)

Tree Protection Plan: Tree protection zones should be established and maintained throughout the entire length of the project. Fencing for the protection zones should be 6 foot tall metal chain link type supported my 2 inch metal poles pounded into the ground by no less than 2 feet. The support poles should be spaced no more than 10 feet apart on center. The location for the protection fencing should be as close to the dripline as possible still allowing room for construction to safely continue. Signs should be placed on fencing signifying "Tree Protection Zone - Keep Out". No materials or equipment should be stored or cleaned inside the tree protection zones.

Any roots to be cut should be monitored and documented. Large roots or large masses of roots to be cut should be inspected by the site arborist. The site arborist may recommend fertilizing or irrigation if root cutting is significant. Cut all roots clean with a saw or loppers. Roots to be left exposed for a period of time should be covered with layers of burlap and kept moist. The site arborist will be on site for the excavation the foundation.

Trenching for irrigation, electrical, drainage or any other reason should be hand dug when beneath the driplines of protected trees. Hand digging and carefully laying pipes below or beside protected roots will dramatically reduce root loss of desired trees thus reducing trauma to the entire tree. Trenches should be backfilled as soon as possible with native material and compacted to near its original level. Trenches that must be left exposed for a period of time should also be covered with layers of burlap and kept moist. Plywood over the top of the trench will also help protect exposed roots below.

Normal irrigation should be maintained throughout the entire length of the project. The imported trees on this site and any oaks near the construction will require irrigation during the warm season months. Some irrigation may be required during the winter months depending on the seasonal rainfall. During the summer months the trees on this site should receive heavy flood type irrigation 2 times a month. During the fall and winter 1 time a month should suffice. Mulching the root zone of protected trees will help the soil retain moisture, thus reducing water consumption.

An inspection of the tree protection fencing may be required. Other inspections will be on an as needed basis.

This information should be kept on site at all times. The information included in this report is believed to be true and based on sound arboricultural principles and practices.

Sincerely,

Kevin R. Kielty David P. Beckham Certified Arborist WE#04 7 6A Certified Arborist WE#10724A

Subject: 25857 Westwind Way, Los Altos Hills, CA 94022

We understand that Mr. and Mrs. Pichai have purchased the above property and are planning to build a new home on it. We live on , right across from their property. The Pichai's home will be very visible to us.

Last week, the Pichais and their architect from Swatt Meier Architects held a review meeting with the neighbors. They shared details of their plan, selected building materials, and a preliminary landscape plan. We found their plans to be respectful of the environment and they observe the building ordinance of Los Altos Hills. We are very supportive of their plans, and we welcome them to the neighborhood.

RE: 25857 Westwind Way-Pichai

To Whom It May Concern:

I am writing this letter in support of the proposed residential project of Anjali and Sundar Pichai at 25857 Westwind Way.

As the owner of the house at and the three (3) smaller adjacent 1.8 acre parcels (apricot orchards) I was very pleased to see the proposed plans. The family residence Swatt Meirs Architects designed will be a beautiful, appropriate and compatible addition to our neighborhood.

We are very much in favor of the planning commission's approval of this project as it will improve the entire neighborhood as well as add a very nice neighbor to our small Westwind Way community.

If I may be of further assistance, please do not hesitate to let me know.

Very truly yours,

Dear Members of the Los Altos Hills Planning Commission,

I am writing in support of the home being planned for the Pichai family at 25857 Westwind Way. I attended a presentation by the architects from Swatt Miers at the property and was very impressed with the beauty and appropriateness of the design. Tasteful, organic, clean lines, warm materials, and with careful attention to how it is situated on the gently sloping property, the design is one I can fully support. While it is a large home, they are within all of the square foot guidelines and several feet below the maximum height. I feel it will blend beautifully into the natural environment.

They did not have a landscaping plan at the time of the presentation, but from what I saw from the other Swatt Miers properties that they showed, and with the architects' vision of warmth and naturalness within a modern sensibility, I can imagine it will thoughtfully designed. I do hope they continue to maintain the existing orchard and incorporate the mature trees into the landscape plan.

Sincerely,

Christine Abraham Lane
