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 PICHAI; 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 3:17 acre parcel located on the southwest corner of Westwind 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 1;981). .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 Westwind 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 ingress-
egress 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.

would be insignificant in size and to the trees health.
pimpacts tree#28 This tree is expected to have no im acts f rom
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 removedto facilitate
construction. These are allsmallimported 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 othem have an abundance o ecay. These tree have a short life span and wil.
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

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 25850 Westwind Way,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
i Hills. We are very supportive of their plans,and we welcome them to the neighborhood.
Sincerely,

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 26000 Westwind Way 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 compatibleaddition 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 andseveral 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
