RESOLUTION NO. 88-86
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF THE
TOWN OF LOS ALTOS HILLS AMENDING RESOLUTION NO. 1256
WHICH ADOPTED A POLICY CONCERNING LANDSCAPING,
AND SETTING OF BONDS THEREFOF
RESOLVED, by the City Council of the City of the Town of Los
Altos Hills, County of Santa Clara, State of California, that
WHEREAS, on January 2 , 1980 the City Council adopted Resolu-
tion No. 1256 entitled:
A RESOLUTION OF THE CITY COUNCIL OF THE CITY
OF
OF THE TOWN LOS ALTOS HILLS ADOPTING A
POLICY CONCERNING LANDSCAPING REQUIREMENTS
FOR SITE DEVELOPMENT AND SUBDIVISION"
and
WHEREAS, the City Council desires to amend Resolution No. 1256
to set standards for landscaping bonds and other minor amendments
to said policy,
NOW, THEREFORE, IT IS HEREBY RESOLVED ORDERED AND DETERMINED as
follows:
Resolution No. 1256 is hereby amended to read as follows :
SECTION 1. The functions of landscaping requirements in
development of a site within the City of the Town of Los Altos Hills,
herein called the "TOWN" must be viewed in connection with the pro-
vision of the General Plan calling for landscaping to create maxi-
mum compatibility of development with the, natural environment. To
this end, landscaping may be required to soften the impact of new
buildings, swimming pools, tennis courts , or driveways , and artifi-
cial cuts and fills as seen from off the site. Because of the hilly,
difficult terrain, the impact of graded roads , new buildings , tennis
courts , and swimming pools may be felt miles away as well as by the
immediate neighbors and the traveling public along the roadway.
+ • •
SECTION 2 . It is recognized that one function of landscaping
is to please the people on whose property the landscaping exists.
This function, is a matter of individual taste, for which the Town.
should not assume responsibility.
SECTION 3. Another major function of landscaping is to pro-
tect the environment, visual as well as natural. In regard to this
function, the Town has the responsibility, according to the General
Plan, .to require planting, replanting, or other measures , where
necessary, to maintain soil stability, to prevent erosion, to abate
noise, to protect the privacy of neighbors and to protect wildlife
habitat, and to retain aesthetic quality.
SECTION 4. The retention of aesthetic quality for the public
at large is a function Of landscaping in which the Town should pro-
tect scenic views and seek to mitigate the effects of large, or
unsightly structures and graded banks.
SECTION 5. The following guidelines are approved to provide
guidance to persons presenting plans for new structures or grading
plans to the Site Development Authority, or persons submitting
proposed subdivision maps to the Subdivision Committee, respectively,
namely: (a) The Town should require only the minimum number _
of plants or other measures necessary to achieve the
functions mentioned above.
A bond shall be posted to ensure that minimum screening
and landscaping requirements are installed and maintained.
•
(b) The Town' s primary interest in landscaping concerns
. the impact on the, views from off the site. The applicants '
on-site views are not the concern of the Town; the effect
of the applicants ' structures on the view of others are
the concern of the Town. The off-site views should be

• • •
considered from both near and far, from the point
of view of existing and possible residences , from road-
ways and pathways .
(c) The unnecessary obstruction of open vistas across
newly-developed property should be avoided.
(d) Plants and shrubbery shall be planted so as not
to encroach on roads and pathways.
(e) The larger the structure, the larger the plants
on other measures should be to soften the effect of the
structure.
(f) Plants placed close to a structure are much more
effective as screening than plants along the perimeter
of the property.
(g) The judicious placement of a few shrubs and trees
near the new structure (especially in meadow or orchard
areas) insures the natural or rural quality of the Town.
(h) The protection of the environment is best served
by the use of native and fire-resistant plants.
(i) . View corridors and open spaces should be considered.
(j ) Landscaping placements should accommodate .requre-
ments for both passive and active solar systems without
sacrificing the aesthetic objectives set forth in this
Resolution.
(k) The Town should address each individual case at the
time of Site Development Authority review only. At this
time, specific recommendations for landscaping should be
made to the applicant and should address those areas
identified in the Guidelines (i.e. , solar access , erosion
control, neighbors views , among others) .
Amending Reso. 1256 -3-

(1) In connection with a subdivision, , the.'Subdivision
Committee should address itself to those aspects, of
landscaping that are broadly stated in the General
Plan, including but not limited to. the following state-
, ment. in the Regional Content, to wit:
" . . .because the planning area is located in .
hillsides visible from a significant part of
the region, the natural characteristics of the.
slopes provide visual relief from the conges-
tion of the mor a -urban areas for a' largenum-.
ber of Bay Area residents. "
The Subdivision Committee also should be concerned with
the off-site view of the hillside, recommending mitigat-
ing landscaping procedures if .needed (e..g terracing cut
hillsides and planting with natural vegetation in addi-
tion to hydromuiching by other measures) , and those areas
which the Town has designated as fire risk areas.
SECTION 6 . The foregoing policy and guidelines shall be imple-
mented as follows:
(a) A checklist (See Exhibit "A Checklist for Prepara-
tion and Submission- of Landscape Plans) (attached hereto '
and incorporated herein) has been developed for use by
the Site Development Authority or Subdivision Committee,
as the case may be, in consultation with the Environmental
Design Committee, and which shall be included in the file
for each application. Individual checklists shall
itemize areas of concern and provide specific suggestions
for mitigation, for example, native vegetation for mini-
mally developed areas, blending schemes for more highly
developed areas , appropriate cover and screening for cut
and fill areas , fire resistant plants for. high fire
hazard areas, among others.
Amending Reso.1256 -4-

(b) Concerning a subdivision, specific conditions re-
lated to landscaping would be included among the condi-
tions adopted when a tentative map for the subdivision is
approved.
(c) Concerning Site Development, if the required land-
scaping is not completed at the time of Final Inspection,
the Site Development Authority shall determine the amount
of the cash deposit of which will be required with a six
(6) month time limit for compliance. The amount of the
cash depositor bond will be based upon the Site Develop-
ments Committee' s determination of the amount of land-
scaping mitigation needed regarding the subject plans.
The amount of the cash deposit or bond shall be as
follows:
(i) Minor mitigation - one thousand dollars
($1,000 . 00)
(ii) Average mitigation - two thousand five
hundred dollars ($2,500 . 00)
(iii) Major. mitigation - five thousand dollars
($5 ,000 . 00) .
If the landscaping is not installed prior to the expira-
tion of the six (6) month period, the Town will use the
cash deposit to complete the landscaping work through
a contract with an independent contractor qualified to
do the required work.

(d) Site Development Authority. The Site Development
Authority may refer any landscape plan to the full
Planning Commission with the request that certain speci-
fic mitigation measures be required to be accomplished
prior to Final Inspection.

CHECKLIST FOR. PREPARATION( AND
SUBMISSION OF LANDSCAPING PLANS: .
To assist you in preparing landscape plans that may be approved with a
minimum of delay or change, the following guidelines have been pre-
pared. Please refer to Article 8 of the Site Development Ordinance,
attached, which contains guidelines and regulations used to evaluate
landscape plans. You or your representative's attendance is "required
at the time the , Site Development Committee discusses your plan, to
answer questions 'and to hear comments.
Plan Requirements :
All landscaping plans submitted for Site Development Committee approval
should have the following format. A modified copy of the grading and
drainage plan (from your Site Development permit application) that fits
these criteria may be used.
-Show the entire property including all improvements; with
particular attention paid to road edges, property lines,
pathways and road easements.
-Scale should:be 1" - 20! .
-Final grades are to be shown in five foot (5) maximum
contours if the lot averages over five (5) percent slope,
and two •(2) foot contours if less than five (5) percent
slope. -
-Building footprint, decks , driveways, installed surfaces,
existing or approved pools, tennis courts , and allother
structures are to be shown,.
-Future or planned pools, tennis courts and building additions
are not to be shown on the landscape plan except for concept
reference. These structures must be clearly labeled as
"future" or "planned" .
-All property lines, pathways , easements, and right-of-ways
are to be indicated.
-Relation of roadway (e.g. , pavement) to property line
shall be shown.
-Streets adjacent to site must be labeled.. .
-The north compass reference is to be shown.
Landscaping:
Landscaping to render structures, unobtrusive fromoff-site and in
conformancewith the provisions of the Site ,Development Ordinance
shall be required by the Site Development Authority as a condition
of approval of a Site Development application. The Town shall _ _
require only the amount of landscaping--necessary to imple--
ment Article 8 of the Site Development Ordinance and the Town's
landscape policy. (Resolution 188-86 -attached) . The amount of
Exhibit "A"
410
landscaping required by the Town shall be determined by the size of
the structure, the types of materials , and the colors proposed for
structures . Applicants should keep the following information in
mind when preparing their landscape plan:
-Applicant' s Plan must show the location and size at maturity
of all plants proposed to meet the requirements of the Site
Development Ordinance, and shall include elevations in suffi-
cient detail for the Site Development Committee to evaluate
the adequacy of proposed landscaping.
-Applicant should review Resolution #88-86, Article 8 and the
list of recommended drought resistant plants prior to prepar-
ing the Landscape Plan. This information is attached, and is
available at Town Hall.
-Plants selected for landscaping must have both their common
English name and their . Latin genus and species shown and
their planting size.
-Applicant' s plan must consider landscaping for front, back
and sides of all structures, pools , and tennis courts (i.e.
front yard landscapingalone is generally inadequate. )
-No structures (e.g. , gateposts , monument style mail boxes,
etc.) are allowed in road rights-of-way. Ordinances that
apply to fence height are interpreted to apply to gateposts .
Zoning Permits are required for any fences or monuments pro-
posed.
-No landscaping or sprinklers are to be permitted in dedicated
pathway easements .
-Existing trees and plantings are to be shown and labeled as
"existing" on the plan.
-Placement of landscaping plants must be sufficiently distant
from roadways and pathways so as not to cause future obstruc-
tion. Road right-of-way extends generally beyond surfaced
roadway; landscaping may be subject to control by the Town.
-Structures along scenic highways will require additional levels
of mitigation.
Administrative:
-It is the applicant' s responsibility to submit landscapingplans
for approval at least six to eight weeks before final inspection
is required.
-While the applicant may submit the Landscape Plan at any time,
the Site Development Committee, as a rule, will delay action on
Landscape Plan for houses until the roof and framing has been
installed, which will allow the Site Development Committee to
assess the impact of the structure from off-site.

ARTICLE 8. LANDSCAPING_
Section 10-2.801. Purpose.
The purposes of this Article. are to create the maximum compatibility of
development with the natural environment; to preserve the rural quali-
ties of the Town; to insure that structures, as viewed from off-site,
blend harmoniously with the natural landscape and are unobtrusive; to
maintain soil stability; to abate noises; to protect wildlife habitats;
to retain aesthetic quality; and to protect properties against fire and
other natural forces.
Section 10-2.802. Landscaping Policies.
(a) Erosion. Landscaping shall be required to control erosion, retard
soil creep, and reduce the potential for landslides.
(b) Noise. Landscaping and berms may be required to shield Town
residents from unnatural noises, such as those from freeways,
arterial streets, and nonresidential land uses.
(c) Visual Effects. Landscaping shall be required to mitigate the
visual effects of development from off the site.
(d) Preferred Plants. Landscaping should utilize fire retardant
species. Native or naturalized plants or other plant species that
blend naturally with the landscape should generally be favored.
(e) Maintenance. Landscaping shall be maintained in healthy condition
by property owners and shall not intrude into easements, paths, or
the lines-of-sight required at intersections and along roads.
(f) Tree Preservation. Every feasible attempt should be made to
preserve existing trees.
(g) Views. In order to prevent blockage of scenic views and vistas,
the height at maturity of proposed plants and trees shall be con-
sidered in determining the appropriateness of landscaping plans.
(h) Amount Required. The Town shall require only the minimum amount of
landscaping necessary to implement the above policies. The amount
of landscaping required by the Town shall be determined by the size
of structure, the types of materials, and the colors proposed for
structures. Structures that blend with the natural landscape will
normally require less landscaping for screening purposes than will
structures composed of non-natural materials and bright colors.
Where slopes are too steep to support continuous ground cover,
niches and ledges may be required for planting. Landscaping may be
required for cuts and fills along public roads.
Section 10-2.803. Site Development.
Landscaping to render structures inconspicuous from off-site and in
conformance with the provisions of this Chapter shall be
—21—
S
required by the Site Development Authority as a condition of approval
of a site development application.
Section 10-2.804.. Preferred Species List.
The Zoning Administrator shall maintain a preferred species list for
distribution to applicants. The list shall note any special qualities
of. particular plant species, such as size at maturity, drought or fire
resistance, soil requirements,. etc.
Section 10-2.805. Size and Placement.
The number and size at maturity of plants used to screen and break up
the outline of structures should be scaled to the size of the struc-
tures and the siting angles from prospective viewing points, the types
of building materials used, and the color scheme of the structure. In
evaluating the adequacy of proposed landscaping, the following guide-
lines shall be considered:
(a) The shape, outline, color, and form of all structures shall be
rendered unobtrusive when viewed from any location off-site at the
time landscaping has matured .
(b) The type of landscaping used shall be sensitive to the natural
topography. For example, on steep slopes, plants that will
maximize erosion control should be selected.
(c) The type of landscaping shall be appropriate for the composition of
the soil in which the plantings are to be located. Required
landscaping should thrive with as little maintenance as possible.
Section 10-2.806. Irrigation Systems.
Sprinklers and other landscape irrigation systems shall not be allowed
in any public right-of-way without an encroachment permit.
Section 10-2.807. Maintenance of Landscaping.
Landscaping shall be maintained in a natural , healthy condition.
Diseased or dead plants shall be replaced. Combustible brush shall be
removed from the site. A minimum of twelve feet (12' ) vertical clear-
ance shall be maintained over driveways, public pathways and public
rights-of-way. Landscaping shall be maintained according to the
conditions of any performance bond filed with the Town.
Section 10-2.808. Fences and Walls.
Any wall or fence may be required to be landscaped.
