INTRODUCTION
The City of Poway desires to have development in an attractive
and high quality manner. These guidelines and specifications for
landscape development will enable designers and developers to clearly
understand the City's intent with respect to landscape design and
management.
It is the intent of this design guideline not only to establish an
acceptable level of quality for approval, but to achieve harmony
with the natural landscape and bring a continuity to the existing
developed areas in the City.
In order to permit and encourage a pleasing aesthetic interaction
with the environment, a landscape design should provide a variety
of shapes, textures, and colors, as well as providing practical
applications such as lawns to walk or sit on, trees to produce
shade and block high winds, and benches. Historical and socio-
logical considerations should not be overlooked.
Wildlife is part of our environment and should be provided for by
using plants that can be utilized for food and cover. In many cases,
shrubs and trees can be grouped together to create wildlife corridors.
Even small groups of the appropriate plants can support some wildlife.
Erosion is one of the major problems facing the City today. With
the accelerated rate of construction, disturbance of our soils and
the subsequent siltation of our storm drains, streams, rivers and
lagoons has been magnified many times over the natural rate. Another
very important reason for concern about erosion and slope stabiliza-
tion is the damage erosion and soil movement can cause to property
and human safety. Plants and their root systems are the most
effective means of retarding raindrop impact and slowing the move-
ment of water over a slope surface. For these reasons, the City
has developed strict slope stabilization standards.
The City is very concerned about proper water management. The City
encourages future design efforts to be conscious of water saving
irrigation systems as well as drought tolerant plant materials.
The use of California natives is highly recommended in landscape
designs.
The judge of any design guideline is not how meticulously that
guideline is followed but in how well it can act as a framework
upon which to build high quality design. If, in that effort to
provide projects of high design caliber, variations from these
guidelines are necessary, any possible exceptions should be sub-
mitted to the City for approval.
These guidelines were adopted by the City Council of the City of
Poway, on February 1 , 1983 by Resolution No. 83-001.

General Desisn Standards
Landscaping in the City of Poway, must be economical an~meet
many needs. Below are some guidelines for sound design that will
help a growing Poway achieve its goals of bringingharmony
with the natural landscape (rather than obliterating it) and ~f
bringing continuity to the existing developed areas in the City.
A well-founded design should:
mo
Integrate with, compliment, and improve the existing permanent
landscape.
Relate to and compliment the architecture of any structures on
the site.
g.
h.
i.
Minimize grading and mitigate erosion.
Provide for screening of unsightly areas and noise as well
as provide for wind and sun control.
Minimize the use of water. Water conservation is stressed
within City limits.
Provide for variety of design elements.
Use native and drought tolerant plant materials where practical.
Make provisions for wildlife where feasible.
Reflect the needs and expectations of those persons affected by
the landscape.
Provide for human comfort by use of benches or other landscape
structures where appropriate.
Landscape Architecture Plan Submittals
Owner/consultant shall submit to the City the required documents
for all projects where landscape improvements are required as a
part of the project development. Submittals may also include model
complexes if so determined by the Planning Director and/or City
Engineer. The construction of a single family home on an individual
lot with no graded slopes does not require the submission of a
landscape plan unless specific 1-~dscape requirements were made as
a condition for approval. Single family units must still conform to
any applicable sections of the City Code and ordinances pertaining
to landscaping prior to occupancy. Ai~ plans submitted shall be
prepared under the direct supervision of a Registered Landscape
Architect, (State of California), with all drawings bearing his
signature (unless specifically waived).
(1)
Preliminary Landscape Plans
Preliminary Landscape Plans for projects requiring a landscape plan
as determined by the Planning Department shall be submitted to the
Planning Department with the project application:
1. Such plans shall clearly indicate:
a. Ail existing vegetation (native, naturalized, or ornamental
trees, shrubs and herbacous areas including street trees
and other parkway plantings).
b. Ail areas in natural state.
c. Tabulation of all vegetation to be removed to accommodate
project.
d Wildlife found on project site.
e Existing topography.
f Proposed slope gradients.
g Maintenance responsibilities designated.
h Trails, walks, fences, walls.
i Cost estimates with quantities and unit costs.
2. Preliminary Plan Submittals:
a. To Planning Department:
· Two sets preliminary landscape plan.
· One set preliminary cost estimates.
*To be evaluated and incorporated into the design review
process. Appropriate items will then become a part of the
conditions of approval as a part of the final tract map
acceptance by the City.
Landscape Plan Submittal and Review Procedures
1. Landscaping or the installation of an irrigation system in the
City of Poway shall not be undertaken until the City Land-
scape Architect and the City Engineer have reviewed and approved
plan submittals and specifications, covering the proposed use of
plant materials and irrigation systems in order to determine:
a. That proposed plant material will be suitable aesthetically,
physiologically, and ecologically for the particular planting
situation.
b. That proposals for soil preparation are adequate as pro-
vided by a certified soils engineer report.
c. That proposed planting will meet minimum requirements as
set forth in Ordinance No. 77, Section 87.208, and will not
violate any provisions of the City of Poway, Grading
Ordinance.
d. That proposed irrigation system will be adequate to properly
irrigate proposed planting and is.in accordance with City of
~oway details and specifications.Ior landscape development.
e. That improvements are permanent and of a nature and quality
to insure low maintenance and operation costs.
f. That all open space and landscaping requirements are met.
2..Plan Check Procedur.es:
a. Initial Landscape Plan Review Submittal
To City Landscape Architect:
· Two sets bluelines
· Two sets specifications
· Two sets irrigation calculations
· Two sets soil analysis report
· Two sets cost estimate
*Allow twelve (12) working days for initial Landscape Plan
Check.
**All contract documents are subject to review (plans, general
conditions of contract, specifications, etc.).
b. Subsequent Review Submittals
To City Landscape Architect:
· Two sets bluelines (corrected if required)
· Two sets specifications (corrected if required)
· Return marked set of plans and specifications if corrections
were required.
Allow six (6) working days for subsequent Landscape Plan Check.
(3)
c. Final Plans for Approval
· One mylar of title sheet for signature.
d. Approved Drawings
· Upon City approval of plans, Owner/Developer shall
deliver to City Landscape Architect two (2) signed
sets of bluelines.
Record Set of Drawings for Public Improvements
a. Prior to the City acceptance of landscape improvements
within public areas (i.e., commencement of one (1) year
maintenance period), Owner/Developer shall provide to
the City:
· One set mylar reproducibles of landscape construction,
irrigation and planting.
Bonding Requirements
Slope stabilization planting and irrigation is bonded as a portion
of the overall grading bond required by the Engineering Department
prior to issuance of grading permits. As certain planting pro-
cedures are bonded at different rates, it is recommended that the
applicant/owner check with the Engineering Department for the current
bonding schedule.
Inspection and Acceptance of Planting and Irrigation System
Installations
Revisions of the landscape plan must be approved by the City
Landscape Architect before any plant materials are installed
inconsistent with the original plan. Submit two sets of the
revised plans to the City Landscape Architect for review.
2. After installation, but prior to backfill, an inspection of the
irrigation system shall be made by the Landscape Inspector of
all points of connection, backflow protection devices, mainlines,
electrical connections, automatic controllers, and control valves.
Contact the City Landscape Architect to arrange inspection sche-
dule at least 48 hours in advance of the desired inspection.
3. Prior to the release for occupancy, an inspection of the com-
pleted landscape installation shall be arranged. This inspection
will include, but not be limited to:
a. An irrigation coverage test.
b. Compliance to approved landscape plans.
c. Condition of plant materials (including street trees and
slope plantings).
d. Any special conditions or approval attached to the project
by the Planning Commission and/or City Council.
Work Performed in Maintenance Assessment District or Public Area
Final acceptance of Landscape Improvements will be made at such time
as all planting is in place and established in a healthy condition
and irrigation systems are installed as shown on approved plans and
in accordance with Poway city standard details and soecifications.
Owner or agent in control of the property shall maintain landscaping
and irrigation systems to the satisfaction of the City Landscape
Architect for one (1) calendar year. After acceptance of improve-
ments by City Council, at which time the Maintenance Assessment
District will be available to service area for continuing mainten-
ance, formally relieving the Contractor of his maintenance responsi-
bilities.
Slope Stabilization
Slope stabilization is a primary concern in the City of Poway
All cut or fill slopes in excess of five (S) feet vertical h~{ght
shall be landscaped and irrigated. This may be waived at the
discretion of the City Landscape Architect. Plant materials on
slopes must be established prior to release of landscape bonds.
Ail slopes or natural areas with elevation differences greater than
40 feet vertical rise, or slopes greater than 10 feet vertical rise
along public streets or areas separated by a fence, wall or other
barrier from the structure, shall be maintained by a Homeowner's
Association, Maintenance Assessment District, or other method
acceptable to the City.
Extreme Erosion Hazards
Extreme erosion hazards such as steep slopes of highly erodable soils,
soils poor in nutrients or impermeable soils, etc., may necessitate
the use of more stringent control measures as determined by the City
Engineer and/or the City Landscape Architect. Such measures may in-
clude, but are not necessarily limited to:
a. Erosion control planting by hydroseeding, plant pots, or cuttings
beyond normal requirements.
b. Placement of erosion control matting.
c. Reduction of slope cuts and embankments.
d. Construction of brow ditches and downdrains.
e. Construction of extension of retaining walls.
f. Soil stabilization treatment.
g. Provisions for subsurface drainage.
h. Special requirements for irrigation.
Fire Prevention
In high fire hazard areas, such as in the suburbs near Chaparral, land-
scaping should include efforts to prevent the spread of fire to struc-
tures. Research by the Fire Retardant Plant Research Project, Los
Angeles State County Arboretum, has shown some plants to be relatively
non-flammable since they withstand high temperatures for prolonged
periods without igniting and do not support open flames when ignited.
Where development occurs adjacent to areas identified as being fire
hazardous, owner shall comply with all appropriate recommendations for:
a. Fire Prevention
b. Fuel Management and Hazard Reduction
c. Fire Control
d. Fire Retardant Plantings
These measures are contained in "Background Report and Recommendations
for the Reduction of Fire Hazard at the Natural Open Space/Urban
Development Interface," Orange County, California, prepared by the
Fire Protection Planning Task Force, September 1976. Refer to the
Slope Planting List for Fire Retardent Plant Materials.

in those flats until transplanting. The flat's soil
shall contain sufficient moisture so that it will not
fall apart when lifting the plants. If plants from
peat pots are used, the pots shall be protected at all
times prior to planting to prevent unnecessary drying
of the root ball.
Ground covers shall be planted in straight rows and
evenly spaced, unless otherwise noted, and at intervals
called out in the drawings. Triangular spacings shall
be used unless otherwise noted on the plan.
(4)
To avoid drying out, plantings shall be immediately
sprinkled after planting until the entire area is
soaked to the full depth of each hole. Evenly spread
ammoniated redwood shavings or other approved mulching
material in the area planted with ground cover to a
depth of 1/2".
C. Planting of Trees, Shrubs and Vines
(1)
Excavation for Planting - Excavation for planting shall
include the stripping and stacking of all acceptable
topsoil encountered within the areas to be excavated
for trenches, tree holes, plant pits, and planting beds.
(a)
All excavated holes shall have vertical sides
with roughened surfaces and shall be of a size
that is at least two times the width and one and
one half times the depth of the original plant
container. The holes shall be, in all cases,
large enough to permit handling and planting
without injury or breakage to the roots or root
ball. Refer to Standard Planting Details #206-209.
(b)
Excavated holes for slope plantings shall be dug
two times original plant container depth, pro-
viding a permanent 6 inch berm around plant pit.

NOTE:
No more plants shall be distributed in the
planting area on any day than can be planted
and watered on that day.
Containers shall be cut and plants shall be
removed in such a manner that the ball of
earth surrounding the roots is not broken,
and they shall be planted and watered as
herein specified immediately after the
removal from the containers. Containers
shall not be cut prior to placing the plants
in the planting area.
Acceptable topsoil which was salvaged during
the digging of planting holes may be used for
backfill. Backfill mix for all container
plants shall consist of the following:
3 parts by volume ammoniated
redwood shavings
6 parts by volume on-site soil
17 lbs.. "Gro-Power" per cu. yd. of mix
Agricultural gypsum (per soil report)
The proportions/contents of this mix may be
altered based on soil report recommendations.
(d)
Backfill shall be placed at the bottom of each
hole and thoroughly compacted to a height that
when a plant is placed in the hole its root
crown is slightly above the established final
grade. Any plants which settle deeper than
specified above shall be raised back to the
correct level. After the plant has been placed,
additional backfill shall be added to the hole
to cover approximately one-half the height of
the root ball. At this stage, water shall be
added to the top of the partly filled hole to
thoroughly saturate the root ball and adjacent

After the water has completely drained,
fertilizer tablets shall be placed as
indicated below:
2 tablets per 1 gallon container
S tablets per S gallon container
4 tablets per iS gallon container
6 tablets per 24" box
8 tablets per $0" box
10 tablets per $6" box
12 tablets per 42" box
14 tablets per 48" box and those box
sizes which are larger
The remainder of the hole shall then be
backfilled.
Set the tablets to be used with each plant
on top of the root ball while the plants
are still in their containers so the re-
quired number of tablets to be used in each
hole can be easily verified.
After backfilling, an earthen basin shall
be constructed around each plant. Each
basin shall be of a depth sufficient to
hold at least six inches of water. Basins
shall be the same size as the container
size of each individual plant. The basins
shall be constructed of amended backfill
material.
Immediately after planting, apply water
to each tree and shrub by means of a hose.
Apply water in a moderate stream in the
planting hole until the material around
the roots is completely saturated from
the bottom of the hole to the top of the
ground.
Apply water in sufficient quantities and
as often as seasonal conditions require
to keep the planted areas moist at all
times, well below the root system of grass
and plants. Generally, water once each
day for 7 days in cool seasons, and for
14 days in hot weather. Berms around
shrubs and trees on slopes shall be
permanently maintained. Maintenance efforts
shall include periodic inspection to prohibit
siltation of material around plant crown. In
turf areas, berms shall be maintained for 30
days following tree planting.
(SS)
Do
(e)
Vine Planting - Vines shall have
wood stake support removed, without
damage to plant and the vine trained
upon the adjacent posts and walls
as directed by the plan, or Landscape
Architect. Vines shall be held to
posts and overheads by plastic green
ribbon - "heavy duty" and plastic
adhesive vine tabs, no nails - as
directed by the City Landscape
Architect.
(f)
Pruning - Pruning shall be limited
to the minimum necessary to remove
injured twigs and branches, and to
compensate for loss of roots during
transplanting, but never to exceed
one-third of the branching structurel
Upon approval of the City Landscape
Architect, pruning may be done before
delivery of plants, but not before
plants have been inspected and
approved. Cuts over three-quarters
of an inch in diameter shall be painted
with an approved tree wound paint.
(g)
Where street trees occur within tree-
wells or are adjacent to a substantial
amount of pavement, a sub-surface
planter box ["Deep-Root" or approved
equal) shall be used. Box shall be
installed per Standard Details #210-212.
Lawn
Lawn will be planted by hand seeding, hydroseeding, and/
or sodding as indicated on the plans.
(1)
After preparation of soil in accordance with the
section on "Grading and Soil Preparation", the
areas to be planted to lawn shall be rolled,
raked, and floated to finish grade by any acceptable
method with the finish grade being smooth and even,
free of rocks and clods and reasonably well firmed.
Prior to planting, the surface of the area shall be
sufficiently loose and'liable to receive the seeds,
or sod.
Pre-fertilization - Just prior to the planting
of turf, evenly broadcast, Gro-Power at rates as
approved in plans and specifications and as
specified under "Materials".
Method
Seed - A satisfactory method of sowing
shall be employed, using an approved
mechanical power drain driller seeder,
mechanical hand seeder, or other
approved equipment. The rate of appli-
cation of seed will be specified
on the plans and in the specifications.
The seed shall be covered by means
of a wire drag, spiked toothed
harrow, cultipacker or other approved
device. Seeded areas shall immediately
be compacted by means of a cultipacker,
roller or other approved equipment
weighing 60 to 90 pounds per linear
foot of roller. Final rolling shall
be at right angles to slopes to prevent
erosion wherever possible.
(bi
Sodding - Soil preparation, finish
grading and fertilization shall be
as specified for seeded lawns,
except that the sub-soil finish grade
shall be two inches below final grade
to allow for the thickness of sod.
Lay sod in one direction only, with
close fitted butt joints. The ends
of each strip shall be staggered to
eliminate continuous joining. Staple
sod on steep slopes with metal staples
typical of those used on erosion
control matting, if necessary.
(S?)
(4)
Watering - Immediately following planting or
top dressing, if applied, apply a light, fine
mist spray to anchor the seed, and/or dressing
to the soil, forming a protective crust to
prevent wind erosion and drying of the seed.
The lawn areas shall be kept moist until fully
germinated.
Fully germinated lawn areas shall be allowed to
dry sufficiently to permit rolling with approximately
two hundred to three hundred pound water weighted
roller to satisfactorily compact the soil around
the grass roots and to provide a firm, smooth
mowing surface.
E. Hydroseeding Installation/Weed Abatement Program
(i)
Weed Control - Upon the completion of the irrigation
system and after all existing weeds and growth
have been removed from the planting area, apply
200 pounds of a commercial fertilizer 16.6.8 per acre,
as per manufacturer's instructions.
Water ali areas four (4) times daily for fourteen
[14) consecutive days and until weed seeds have
germinated. Cease watering for three [3) days. Spray
a non-selective herbicide "Round-up," to eradicate
the germinated weeds. Translocation period should
be 7-10 days.
Allow herbicide to kill all weeds. Rake or hoe
off all dead weeds to a depth of 1/4 inch below
the surface of the soil.
If perennial weeds or grasses still exist, rewater
four [4) times daily for fourteen (14) consecutive
days, until the new growth appears. Reapply a
non-selective herbicide. Remove weeds after herbicide
has had sufficient time to kill.
(2)
Equipment - Hydraulic equipment used for the application
of the fertilizer, seed and slurry of prepared wood
pulp shall be of the "Super Hydroseeder" type as
approved by the Landscape Architect. All seed will be
delivered to site in sealed bags with guaranteed analysis.
(58)
(3) Preparation - The slurry preparation shall take
place at the site of work and shall begin by
adding water to the tank when the engine is at
half throttle. Then the water level has
reached the height of the agitator shaft, good
re-circulation shall be established and the
fertilizer shall then be added to the mixture
when the tank. is at least one-third filled with
water.
The engine throttle shall be opened to full speed
when the tank is half filled with water. Ail the
wood pulp mulch shall be added by the time the
tank is two-thirds to three-quarters full. At
this time the seed shall be added ~praying shall
~commence ~mmediatelywhen the tank is full.
Application - The operator shall spray the planting
areas with a uniform, visible coat by using the
green color of the wood pulp as a guide. THe
slurry shall be applied in a sweeping motion,
in an arched stream so as to fall like rain
allowing the wood fibres to build on each other
until a good coat is achieved and the material
is spread at the required rate per acre.
(S) Time Limit - All slurry mixture which has not
been applied to the slopes within four hours
after mixing will be rejected and removed from
the project at the Contractor's expense.
(6) Protection - Special care should be exercised
by the Contractor in preventing any of the
slurry to be sprayed inside any reservoir basin
or onto drainage ditches and channels which
may impede the free flow of rain or irrigation
water. Any slurry spilled into restricted
areas shall be cleaned up at the Contractor's
expense to the satisfaction of the owner or
City.
Ail areas designated for hydroseeding shall be
thoroughly watered prior to the hydroseeding.
The Contractor shall note any discrepancy for
complete water coverage and correct. The
Contractor shall at this time note wind and
weather conditions and submit a watering program
to the Landscape Architect for approval prior
to hydroseeding.
(S9)
(7)
Reseeding - Ail bare spots shall be reseeded
by the Contractor within 10 days. The Contractor
will be responsible for all reseeded areas for
as long after seeding as necessary until an
acceptable stand of hydroseeded material is
realized and approved by the City.
(8) Watering
(a)
A balanced full-coverage watering
program shall be maintained to ensure
proper germination and until the
acceptance of work.
Plants which cannot be watered
efficiently with the existing water
system shall be watered by means of
a hose.
(9)
Fertilization (turf) - Apply 25 lbs. "Gro-
Power" per 1000 square feet 4S days after the
first mowing. Continue every 190-120 days.
F. Erosion Control
Erosion control installation will be required in
locations specifically delineated on the drawings
or as necessary due to field conditions.
(i)
Surface of the slopes shall be uniformly smooth
and even with all debris and rocks raked out.
The soil shall be sufficiently moist to permit
the firm laying of erosion control matting and
to prevent sloughing of topsoil.
(2)
The erosion control matting shall be laid with
the direction of flow of surface drainage, and in
accordance with the manufacturer's directions.
The matting shall be cut to provide a visually
pleasing slope.
The matting shall be stapled in place and firmly
embedded by means of tamping or rolling, as
approved by the City Landscape Architect,
to insure that the matting is in contact with
the soil and that no erosion can take place under
the matting.
(4)
Planting of turf, ground covers, shrubs and/or
vines may be required in areas protected by
erosion control matting as specified in the plans
or as become necessary.
(60)
Natural Planted Areas

CITY OF POWAY
GUIDELINES & SPECIFICATIONS FOR
LANDSCAPE DEVELOPMENT
APPROVED SLOPE PLANT MATERIALS
Slope planting design within publicly maintained areas shall
conform to the following guidelines:
(a)
Ail trees shall be hand-planted. Fast growing
types may be used for erosion control, but root-
bound plants will not be accepted. Fast growing
tree material shall be planted from 1 gallon and
5 gallon containers (maximum size). Use of hydro-
seeded tree materials shall receive the approval
of the City.
Mass planting of informal shrubs, drought tolerant
in nature and well adapted to slope conditions,
shall be encouraged throughout the City. Use of
California natives with ground covers with com-
patible water requirements is recommended.
Ground cover shall be hand-planted or hydroseeded.
The use of native or introduced grasses and ground
cover on slopes is encouraged. Tall growing annual
material shall not be used.
(d)
Desirable overall appearance shall consist of
masse~ shrubs (large and small scale), erosion
control ground cover, and trees. Designer shall
attempt tcrelieve the "planed" appearance of manu-
factured slopes through effective slope planting
design.
(e)
Hydroseed mixes shall be designed such that com-
ponent mixture presents no particular maintenance
problems (excessive hand-weeding among newly
germinated plants). The intent here is to keep
seed mixes as simple as possible in order to
achieve the proposed results.
(f)
Hand planted slope materials shall be selected with
consideration for particular environmental/soil
conditions as they occur:
1. Fire retardance
2. Difficult soil types (shale, sterile, etc.)
3. Drought tolerance
4. Aesthetic appearance to the public
5. Slope gradient
6. Economy of materials and construction
Major slope areas, privately owned but clearly within
public view (adjacent to major public access), shall
generally conform to the above guidelines.
(68)
SOIL COORDINATED PLANTINGS FOR POWAY
The geology of the Poway area consists of a series of soil and
rock formations, which though occur in close proximity laterally
and vertically, differ significantly in appearance, composition,
stability and erosion susceptability, and reception to the
introduction of plant material. Due to the frequent variation in
significantly different soil types throughout the City, and even
within a project area, comprehensive soils reports must be prepared
to guide proper selections of plant material, planting techniques,
and complementary irrigation systems.
SOIL TYPES
General soil types and brief characteristics of each are summarized
as follows:
(a) Basal Rock the general rock formations in the area appearing
as a grey-green dioritic rock or a reddish cast iron oxide
composition is visible as large out-croppings and boulders.
(b) Decomposed Granite - a product of erosion of the granite, it
occurs in pockets throughout the Poway area, and is characterized
as physically unstable. It has a mineral nutrient content, and
supports the Coastal Sage Community. Plant selections must
include adequate groundcover plantings to stabilize surface
erosion.
(c) Friars Formation - appearing as grey-green clay lenses typically
occurring on the lower slopes of hills, it is relatively
resistant to erosion. Due to its poor drainage, it supports
limited plant growth other than seasonal grasses.
(d) Weathered alluvium - composed of sands rich in iron giving it
a distinct red color, it occurs at the base of hills and as
valley soil and has typically developed into fairly hospitable
soil for plants, supporting the Valley Grassland and Oak
Woodland communities.
(e) Stadium Conglomerage - is a water-deposited formation of rounded
cobblestones appearing as the top layer of many of the hills in
the Powa¥ area. The formation is marked very clearly by the
sudden beginning of the Coastal Sage Scrub Community.
(f) Lusardi Formation - obvious as patches of very large slightly
rounded boulders near the crest of several local hills. It is
not a vegetation-supporting material.
Because of the extremes in drainage and fertility characteristics of thc
local soils; plant selection, soils preparation, planting techniques,
and irrigation practices must be properly analyzed and incorporated int(
the plans and specifications.
The ease in which submittals of plans and specifications reach city
approval will be significantly influenced by the thoroughness of the
Landscape Architect in identifying and properly executing the above
referenced procedures. The plan reference to "typical Powa¥ soils" will
not be found acceptable; but rather returned to the designer for
proper execution.
