Driveway &Parking
In addition to retaining the existing driveway access from the ingress egress easement on
the west side of the property, the applicant is proposing a new, secondary driveway access
at the end of the Fremont Pine Lane cul-de-sac. The driveway on the west side will
provide access to the basement garage while the driveway on the north side will lead to an
auto court in front of the new residence.
The basement garage will provide three (3) covered parking spaces with standard
dimensions of 10' x 20'. One (1) additional outdoor parking space is provided in the auto
court in front of the house outside of the required setbacks.
Trees &Landscapes
The property is heavily vegetated with various mature trees and shrubs. A total of twenty
(20) trees, mostly eucalyptus and pines, will be removed as part of this site development
project. Two multi-trunk heritage oak trees located within the vicinity of the new
building are proposed to be removed and replaced with two (2) 60" box oak trees at the
driveway entrance. (Condition #5) The size, type, and location of the trees to be removed
are shown on the attached tree status plan.
After completion of rough framing and prior to the time of the pre-rough framing
inspection by the Planning and Engineering Departments, the applicant will be required to
submit a landscape screening and erosion control plan for Site Development Committee
review and any planting required for screening or erosion control will be required to be
planted prior to final inspection. (Condition# 2)
To ensure the protection and preservation of the remaining oak trees on the site, staff is
recommending the implementation of the tree protection plan provided in the arborist
report prepared by McClenahan Consulting, LLC dated August 31, 2005. (Attachment 6)
Outdoor Lighting
All proposed outdoor lighting are located outside the setbacks except for two (2)
driveway column lights and five (5) step lights on the driveway retaining wall and stairs.
The step lights on the driveway retaining wall and stairs are required for safety and will
be louvered to minimize their visibility. Staff has included condition #8 requiring light
fixtures to be down shielded, low wattage, and the source of the lighting not be directly
visible from off-site.

Grading
Total grading quantities include 2,290 cubic yards of cut (basement, house, and
swimming pool) and 450 cubic yards of fill (driveway and auto court). The Engineering
Department report states that the applicant is proposing up to 13 of cut in an area of
1,200 square feet. This exceeds the Town's maximum allowable cut differential of 8' for
driveways. The grading involves approximately 375 cubic yards of soil excavation and up
to 13' of cut at contour elevation 239 to accommodate the driveway that leads to the
basement garage.

West (Side) Elevation
The Town's Grading Policy states that "driveway cut may be increased up to a maximum
of eight feet (8') for the portion of the driveway or backup area which is adjacent to a
garage that has been lowered with a similar amount of cut." Additionally, requirements
for building siting is addressed in Section 10-2.702.c of the Los Altos Hills Municipal
Code:
"The location of all structures should create as little disturbance as
possible to the natural landscape. The amount of grading, excavation, or
fill shall be the minimum necessary to accommodate proposed structures,
unless grading is proposed to lower the profile of buildings. Additional
grading may be allowed for the purpose of lowering the profile of the
building provided that at the completion of the project the visual
alteration of the natural terrain is minimized. The removal of vegetation
and alteration of drainage patterns shall be the minimum necessary to
accommodate the proposed structure."
The Grading Policy is intended to be used by staff in evaluating and making
recommendations to the Planning Commission and/or City Council regarding site
development applications, and as guidance for applicants. Individual sites may dictate a

need to deviate from the criteria, to the extent permitted by the Planning Commission
and/or City Council.
If the proposed grading were to occur on a hillside or ridgeline property, the excavation
for the driveway and basement garage would result in massive retaining walls that are
highly visible and substantial visual alteration of the natural terrain in violation of Section
10-2.702.c of the Site Development Code. However, in this case, the lot is relatively flat
and the proposed grading will help lower the profile of the new home. Furthermore, the
driveway retaining walls will be below natural grade and will not be highly visible from
surrounding properties and streets.
If the Commission decides to approve the project as proposed, findings for approval of
the Grading Policy Exception should be cited. (Attachment 2)
Drainage
Pursuant to Section 10-2.503, Drainage Facilities Standards, of the Municipal Code, the
Engineering Department has reviewed and determined that the proposed drainage design
complies with Town requirements. Water runoff generated from the new development
will be collected and carried to a detention basin and dissipates to a grassy swale at the
northern portion of the property. The applicant's engineer has provided storm flow
analysis and calculations showing that the proposed drainage improvements will mitigate
impacts of the site development and the quantity and flow rate of onsite surface runoff
will not increase.
Fire Department Review
The Santa Clara County Fire Department is requiring standard conditions including
premise identification and the installation of fire sprinklers throughout the building. The
requirements are included as conditions#s 27-30.
Committee Review
Pathways Committee-The Pathways Committee recommends dedication of a path
Y
easement over the existing 32' ingress egress easement along the west property line for
public access. (Condition #25) In determining whether a path easement should be
required on the property, questions have been raised on whether the area on the west side
of the property is a private driveway or a private road. Staff researched the property
records and found the following:

2. The Engineering Department's Public and Private Road Records dated March 20,
1998 refer to this easement as a "shared private driveway". This easement was
granted to Town for ingress and egress per Grant Deed No. 1702583 recorded in
Book 4561 of Official Records, page 482 on October 1, 1959. (Attachment 5)
3. The Town's Master Path Plan approved by the City Council on March 8, 2005 does
not show a designated off-road path over the subject property.
If the Commission determines that a path easement is not required on this property, staff
should be directed to modify condition #25 and require the property owner to pay the
pathway in-lieu fee as established by the City Council.
Environmental Design Committee-The Environmental Design Committee noted that
landscape mitigation will be needed along the west property line to replace the grove of
eucalyptus trees that will be removed as part of this site development proposal.

RECOM ENDED FINDINGS FOR GRADING POLICY EXCEPTION
LANDS OF CORRIGAN, 13920 FREMONT PINES LANE
File#7-06-ZP-SD-GD
1. The proposed grading is- in substantial conformance with the General Plan
Land Use Element General Principle#1 which states that"Uses of land should
maintain the rural atmosphere, minimize disturbance to natural terrain,
minimize removal of the natural vegetation and create the maximum
compatibility of development with the natural environment through site
design, architecture and landscaping."
2. Consistent with Section 10-2.702.c of the Los Altos Hills Municipal Code, the
proposed grading will help lower the profile of a portion of the structure and
render it less visible from off-site.
3. The proposed area of grading is not on a hillside and will not result in the
substantial visual alteration of the natural terrain. The property's existing
contours and basic landform are retained.
ro osed grading will not result in the placement of retaining walls that
4. Thep p gr g p g
are visible from off-site.
5. The proposed grading will not result in the removal of any substantial
vegetation or alteration of existing drainage patterns.
6. The Grading Policy emphasizes cut to lower the profile of structures over fill
or foundation walls, which tend to raise the profile of the structure. The
proposed underground garage requires no fill.

RE: 13920 Fremont Pines Lane
Los Altos Hills, California
Assiqnment
As requested, I inspected 25 trees to determine species, size, condition, impacts from
proposed site improvements and provide Tree Preservation Guidelines.
Summary
The site consists of an old house and accessory structures scheduled to be demolished.
Proposed plans include new home construction, landscape improvements and removal
of 17 trees (#1-11, 13-16, 18 and 23). Adoption of Tree Preservation Guidelines will
enhance the prognosis of trees to remain.
Methodology
No root crown exploration, climbing or plant tissue analysis was performed as part of
this survey.
In determining Tree Condition several factors have been considered which include:
Rate of growth over several seasons;
Structural decays or weaknesses;
Presence of disease or insects; and
Life expectancy.
The following guide for interpretation of Tree Condition as related to Life Expectancy is
submitted for your information.
0 - 5 Years = Poor
5 - 10 Years = Poor to Fair
10 - 15 Years = Fair
15 - 20 Years = Fair to Good
20 + Years = Good

24: Modesto ash (Fraxinus velutina `Modesto)
Diameter: 26.5"
Height: 45' Spread: 40'
Condition: Poor to Fair '
Observation:
Foliar canopy is sparse with a moderate accumulation of deadwood. Bifurcation at four
feet creates an inherent structural defect. Proposed driveway is approximately 12 feet
from the trunk. Due to existing conditions, the prognosis is questionable. Adoption of
Tree Preservation Guidelines will enhance prognosis.
Conclusion
Proposed plans will require removal of 17 trees (#1-11, 13-16, 18 and 23). Adoption of
Tree Preservation Guidelines will enhance the prognosis of trees to remain. The
designated Tree Protection Zones are a minimum distance of five times the trunk
diameter. A qualified arborist must monitor any excavation or other work to encroach
within the TPZ.
TREE PRESERVATION GUIDELINES
Tree Preservation and Protection Plan
In providing recommendations for tree preservation, we recognize that injury to trees as
a result of construction include mechanical injuries to trunks, roots and branches, and
injury as a result of changes that occur in the growing environment.
To minimize these injuries, we recommend grading operations encroach no closer than
five times the trunk diameter, (i.e. 30" diameter tree x 5=150" distance). At this
distance, buttress/anchoring roots would be preserved and minimal injury to the
functional root area would be anticipated. Should encroachment within the area
become necessary, hand digging is mandatory.
Barricades
Prior to initiation of construction activity, temporary barricades should be installed
around all trees in the construction area. Six-foot high, chain link fences are to be
mounted on steel posts, driven 2 feet into the ground, at no more than 10-foot spacing.
The fences shall enclose the entire area under the dripline of the trees or as close to the
drip line area as practical. These barricades will be placed around individual trees
and/or groups of trees as the existing environment dictates.

Mr. Sean Corrigan
Page 8 August 31, 2005
The temporary barricades will serve to protect trunks, roots and branches from
mechanical injuries, will inhibit stockpiling of construction materials or debris within the
sensitive 'dripline' areas and will prevent soil compaction from increased
vehicular/pedestrian traffic. No storage of material, topsoil, vehicles or equipment shall
be permitted within the tree enclosure area. The ground around the tree canopy shall
not be altered. These barricades should remain in place until final inspection of the
building permit, except for work specifically required in the approved plans to be done
under the trees to be protected. Designated areas beyond the driplines of any trees
should be provided for construction materials and on site parking.
Root Pruning (if necessary)
During and upon completion of any trenching/grading operation within a tree's dripline,
should any.roots greater than one inch (1") in diameter be damaged, broken or severed,
root pruning to include flush cutting and sealing of exposed roots should be
accomplished under the supervision of a qualified Arborist to minimize root deterioration
beyond the soil line within twenty-four(24) hours.
Pruning
Pruning of the foliar canopies to include removal of deadwood is recommended and
should be initiated prior to construction operations. Such pruning will provide any
necessary construction clearance, will lessen the likelihood or potential for limb
breakage, reduce 'windsail' effect and provide an environment suitable for healthy and
vigorous growth.
Fertilization
A program of fertilization by means of deep root soil injection is recommended with
applications in spring and summer for those trees to be impacted by construction.
Such fertilization will serve to stimulate feeder root development, offset shock/stress as
related to construction and/or environmental factors, encourage vigor, alleviate soil
compaction and compensate for any encroachment of natural feeding root areas.
Inception of this fertilizing program is recommended prior to the initiation of-construction
activity.
Mulch
Mulching with wood chips (maximum depth 3") within tree environments (outer foliar
perimeter) will lessen moisture evaporation from soil, protect and encourage
adventitious roots and minimize possible soil compaction.

Inspection
Periodic inspections by the Site Arborist are recommended during construction
activities, particularly as trees are impacted by trenching/grading operations.
Inspections at approximate four(4) week intervals would be sufficient to assess and
monitor the effectiveness of the Tree Preservation Plan and to provide
recommendations for any additional care or treatment.

B. Properties reviewed for a recommendation are as follows:
i. 13080 Alta Tierra Rd. (Lands of Gruenholz) The committee recommended

easement and path should continue around the corner onto the side of the
property along La Paloma. Here the easement and path should be separated
from the road, with the drainage ditch running between the easement/path and
the road. A culvert will need to be installed to bring the path back to the
roadside to connect with the path on adjacent property on La Paloma.
Ginzton moved, Brunzell seconded. 7 yes, 1 no, 1 abstain.
ii. 13920 Fremont Pines Lane. (Lands of Corrigan) A private road now extends
from the cul de sac to the top of the hill, serving this property and 4 additional
houses. The committee recommended an easement adjacent to the road be
granted for public access along this private road.
Duwe moved, ? seconded. 7 yes, 1 no. (Corrigan excused herself from
voting.)

2B path, separated from the Miranda Road surface.
Ginzton moved, Stutz seconded. Unanimous.
iv. 25045 Oneonta. (Lands of Boynton). It was noted that Foothill College and
the Town are working on major pathway improvements on the Foothill
College side of El Monte. Since El Monte is designated as a 2-sided road for
pathway purposes, the committee recommended an easement along the El
Monte side of the property. The easement must run well back from the top of
the bank sloping down to El Monte.
Duwe moved, ? seconded. 5 yes. 1 no. 3 abstain.
v. 27641 Purissima Road. (Mad Manor subdivision). On Saturday's walk the

POLICE'REGARDING GRADING
Policy Re: Grading
Code Sections and Design Guidelines:
Section 10-2.702(c) of the Site Development Ordinance states that: "The amount of-
grading, excavation, or fill shall be the minimum necessary to accommodate proposed
structures, unless grading is proposed to lower the profile of buildings." Section 10-
2.703(a) requires that: "Type II foundations - step=on-contour, daylight, pole foundations,
or a combination thereof- shall be used on building sites with natural slopes in excess of
fourteen percent'(14%)." Policy A-2 of Goal I of the Design Guidelines (p. 5) indicates
that construction should "blend with the contour of the land." Policy A-2 of Goal If (p.
14) indicates that: "On a sloping site, the structure should be stepped down the hill
utilizing one story building elements. Avoid cantilevers and stilts over downhill slopes.
Cut foundations should be used instead of fill on hilly terrain."
Intent:
The purpose of this policy is to outline desired criteria for grading which assure that
construction retains .the existing contours and basic landform of the site to the greatest
extent feasible. It is also intended that the policy provide guidance for "stepping"
structures down sloped hillsides, and emphasizes cut to lower the profile of structures
over fill or foundation walls, which tend to raise the profile of the structure. While
balanced cut and fill is desirable to minimize import or export of soil to.onfrom a site, it
is recognized that the Town's policies and the guidelines below may encourage export as
cut is generally preferred over fill.
These policies are intended to be used by staff in evaluating and making
recommendations to the Planning Commission and/or City Council regarding site
development applications, and as guidance for applicants. Individual sites may dictate a
need to deviate from the criteria, to the extent permitted by the Planning Commission
and/or City Council.
Policy Re: Grading
page 2
Policies:
1. Cuts and fills in excess of the following levels generally will be considered
excessive and contrary to Town ordinances and policies to grade only to the
minimum-extent necessary to accommodate strictures and to site structures
consistent with slope contours,i.e.,"step down" the hill*:
Cut Fill,
House 8'** Y
Accessory Bldg. 41 Y
Tennis Court 61 39
Pool 4'*** Y
Driveways 4' Y
Other (decks,yards) 49 Y
Combined depths of cut plus fill for development other than the main
residence should be limited to 6 feet,except that for tennis courts cut
plus M may be permitted up to a maximum of 8 feet.
Excludes basements meeting Code definition.
Excludes excavation for pool.
2. The height of the lowest finished floor(s) of a structure should generally not
be set in excess of three (3) feet above the existing grade, to assure that
structures step with the slope.
3. Driveway cut may be increased up to a maximum of eight feet (8') for the
portion of the driveway or backup area which is adjacent to a garage that
has been lowered with a similar amount of cut.
4. Cat and/or fill for drainage shall be limited consistent with the guidelines set
forth above for each type of structure, but shall, be the minimum grading
needed for drainage purposes, as determined by the City Engq*ne* er-
