STONERIDGE HEIGHTS TRAFFIC ANALYSIS
I.
INTRODUCTION
An analysis has been conducted to determine the traffic issues related to the
development of the Stoneridge Heights project in North Poway. The primary
objective of the analysis was to identify development constraints with regard to
traffic and 'access. In the following sections, the results of the analysis are
summarized. First is a description of the existing and planned transportation
system. Next is a discussion of the existing and future traffic conditions on the
streets and highways in the project vicinity. Finally the traffic - related constraints
are identified and mitigation measures are outlined.

DESCRIPTION OF EXISTING AND PLANNED
TRANSPORTATION SYSTEM
Access to the Stoneridge Heights study area is provided by Espola Road on the
south and Highland Valley Road on the north, as shown on Figure 1. Old Coach
Road extends northerly into the project site from Espola Road, while Sycamore
Creek Road extends toward the project site from Highland Valley Road. Other key
roadways in the area include Pomerado Road, Rancho Bernardo Road (which is
essentially an extension of Espola Road), Bernardo Center Drive, Bernardo Heights
Parkway, and Camino del Norte. Martincoit Road and Stone Canyon Road provide
access to the residential area south of Espola Road. Regional access is provided by
Interstate 15 (Escondido Freeway), which has interchanges at Pomerado Road,
Rancho Bernardo Road, Bernardo Center Drive, and Camino del Norte.
There are three current planning documents which have circulation elements
relating to the Stoneridge Heights study area: the City of Poway Comprehensive
Plan, the City of San Diego General Plan, and the Rancho Bernardo Community
Plan. Each of these documents has a functional classification plan by which the
area's streets and highways are categorized as to the primary circulation function.
Table 1 indicates the functional classification of each facility, as designated in the
three planning documents. The three plans are not necessarily consistent among
themselves. The design standards for each street classification are summarized on
Table 2.
® The right -of -way widths, pavement widths, and numbers of lanes designated in the
® planning documents cited above reflect the ultimate design of the streets and
highways in the study area. There are several locations at which the existing
roadways have not yet been constructed to their full width. Figure 2 indicates the
existing number of lanes and the planned number of lanes for each segment of
roadway in the study area.

iThere are several proposed roadway improvements which will have an effect on the
study area transportation system. In conjunction with the development proposed
along Espola Road south of the project site, Espola Road will be widened to four
lanes within the limits of the development. As additional development occurs
along Espola Road, it will likewise be widened such that Espola Road will
ultimately be a four lane facility throughout its length. Another planned highway
project which will affect the .area's traffic patterns, if implemented, is the
Route 125 project. The north end of the proposed freeway /expressway would
traverse the City of Poway and connect with Interstate 15 at the Camino del Norte
interchange.

EXISTING AND PROJECTED TRAFFIC CONDITIONS
1
Traffic conditions on the study area roadway network have been quantified by
collecting and assembling traffic volume data and determining the volume to
capacity ratios and levels of service at critical locations. Existing average daily
traffic volumes which were obtained from SANDAG and represent the year 1985,
are shown on Figure 3. Figure 4 shows the future traffic volume projections,
representing the year at which the general plan land uses would be built out. Data
for the future traffic volumes were not as extensive as for existing conditions. The
source of the projected traffic data is the SANDAG Route 125 North Location
IAnalysis traffic model.
1 An important indicator of traffic conditions on, a highway network is the ratio
between traffic volumes and the theoretical capacity of each roadway segment.
Roadway capacity is generally defined as the number of vehicles which can
reasonably be expected to pass over a section of road in a given time period.
Congestion, accident rates, quality of traffic flow, and environmental acceptability
1
are criteria used in defining a particular roadway's effective capacity. The
desirable daily capacities assumed for the facilities in this study area are
45,000 vehicles per day (vpd) for a six -lane Primary Arterial; 30,000 vpd for a four -
lane Major Street; 20,000 vpd for a four -lane Secondary Street; and 10,000 vpd for
a two -lane Collector Street. These daily capacity figures represent estimates of
the amount of daily traffic which will result in the maximum desirable peak hour
traffic volumes (level of service C). Table 3 indicates the volume to capacity
ratios for each roadway segment in the study area, based on existing ADT's and
number of lanes. The table indicates that every roadway segment currently
operates below the desirable daily capacity of 1.00. This does not imply, however,
that there is no congestion along these routes during the peak periods, because the
peak hour intersection analysis does indicate that there is congestion at certain
intersections. The volume to capacity analysis indicates that the basic number of
lanes on each facility is adequate for accommodating the existing traffic volumes.

A volume /capacity analysis has also been conducted for the projected (year 2005)
traffic volumes and the planned roadway network, the results of which are shown
on Table 4. Several facilities will have exceeded the daily roadway capacity, as
indicated by volume /capacity ratios which are 1.00 or greater. The problem
segments include Rancho Bernardo Road, Bernardo Center Drive, Camino del
Norte, and Interstate 15. It must be kept in mind that the assumptions used in
forecasting these traffic volumes were based on full buildout of the land uses
designated in the general plan, including the Stoneridge Heights project area.
rA
hour intersection to the
peak analysis was conducted evaluate conditions under
which the nearby signalized intersections currently operate during the peak period.
Data were obtained at three critical intersections along Rancho Bernardo Drive, as
these intersections would be directly affected by a development at Stoneridge
Heights. The results of the level of service analysis are shown on Table 5. Level
of service is a qualitative indicator of intersection conditions as determined by
such criteria as delay, congestion, lane configurations, signal phasing, and
volume /capacity ratios. It is measured from A to F (best to worst) with A, B,
and C representing acceptable conditions; D and E approaching the capacity of the
intersection; and F representing severe congestion. Table 5 indicates that the
intersection of Rancho Bernardo Road at Bernardo Center Drive operates near
capacity (level of service E), while the intersection of Rancho Bernardo Road at
Pomerado Road is severely congested during the peak hour (level of Service F).

CONSTRAINTS TO SITE DEVELOPMENT
As a result of the technical analysis summarized in Sections II and III, several
issues regarding traffic and access have been identified as possible constraints to
development at Stoneridge Heights. Each issue is presented below with a brief
description of the constraints and a discussion of potential means for alleviating
the severity of the constraints.
® DIRECT ACCESS TO THE PROJECT SITE
Access to the site is currently provided by a single two -lane road, which is Old
Coach Road. Old Coach Road intersects with Espola Road at an unsignalized "tee"
intersection on the southern boundary of the project site. Site access must be
upgraded so that it does not become a constraint to the level of development.
Access could be improved with one or more of the following measures:
• Widen Old Coach Road
• Improve the intersection of Old Coach Road at Espola Road
• Provide additional access points onto Espola Road
• Provide a northerly access route to connect to Highland Valley Road
• Connect the Stoneridge Heights internal circulation system with the
existing street network to the west, thus providing, an additional outlet
via Cloudcroft Drive and Valle Verde Drive.
The last two measures create additional constraints as they could each be a
controversial idea. There may be problems in providing a northerly connection
because the site does not abut an existing public street right -of -way. A new route
would cross private property and would involve two jurisdictions: the Cities of
Poway and San Diego. Access via the existing streets would be controversial
because it would increase traffic volumes on neighborhood streets.

ROADWAY CAPACITY ON THE STREET NETWORK
The street network providing access to the project vicinity acts as a constraint
because development at Stoneridge Heights would increase traffic volumes on the
roadway network. Development would be limited to a level at which the resulting
traffic volumes remain below the capacity of the roadway system. Figure-5
indicates the. unused capacity of each highway segment, as- determined by
subtracting the existing daily traffic volumes from the desirable capacity. The
numbers on Figure 5 represent the number of daily trips which could be added to
each street without exceeding the street's capacity.
A similar analysis has been conducted using the projected 2005 traffic volumes and
capacities. The unused steet capacities for this scenario are shown on Figure 6.
A bottleneck analysis of the unused capacity numbers on Figures 5 and 6 reveals
that the street network could accommodate approximately 20,000 additional trips
from the Stoneridge Heights development under existing conditions (assuming that
no other development would occur), and 15,000 additional trips in the future
(ignoring the fact that the freeway is over capacity in the future).
INTERSECTION CAPACITY DURING THE PEAK HOUR
The intersection level of service analysis indicates that the intersection of Rancho
Bernardo Road at Pomerado. Road currently operates at its capacity during the peak
hour, and would therefore be a constraint to development. The intersection could
relatively easily be improved by providing double left turn lanes on the southbound
and eastbound approaches. Such an improvement could be accomplished within the
existing pavement width by restriping the pavement. With this improvement the
intersection would operate at level of service C.

Attention Mr. George Hallstein
SUBJECT GEOTECHNICAL SITE REVIEW
Stoneridge East
Poway, California
Gentlemen
In accordance with your'request we have completed a geotechnical review
of the site, to be utilized in development planning. The major factors
affecting development include non - rippable bedrock, and compressible
alluvium or colluvium.
For our investigation, we were provided with 200 -scale topographic maps,
prepared by PRC Engineering..
1.0 INTRODUCTION
1.1 Proposed Development
It is our understanding the development of the site will be primarily
medium to low density residential. Development will be limited
by steep terrain and the feasibility of excavating the granitic
bedrock. At the time of this report no specific plans are available.
1.2 Scope of Work
The scope of services provided for this geotechnical investigation
included

U
2.0 SITE DESCRIPTION
The subject site i.s located in a mountainous relatively undeveloped
portion of northern Poway. Access to the site is from Espola
Road to Old Coach Road. Old Coach Road traverses the site from north
to south. The approximate site boundaries are shown on the attached
Location Map, Figure 1.
Topographically the site is characterized by moderate to steeply
sloping mountainous terrain. The major drainage patterns trend
north -west and drain into the San Dieguito River Valley Site
elevations range from approximately 400 feet adjacent to the
river valley,. to 1,180 feet for the northern mountain peaks. (See
Geotechnical Maps, Plates 1 and 2).
r
Vegetation on the site varies from thick chaparral to grasses,
with scattered groves of trees in the canyons.
Improvements on the site consist of a north -south traversing
electric transmission line, a small portion of the San Diego
aqueduct crossing the south corner of the -site, and numerous
dirt roads and trails.

Geologic Setting
The subject site is located in the Peninsular Ranges Geomorphic
Province of California near the western margin of the southern
California batholith. The batholith, consisting of Mesozoic
granitic and metavolcanic rocks,underlies the entire site. The
topography within the site displays the typically rugged landforms
developed over these rocks.
Specifically, the site is underlain by granitics and surfical
alluvial and colluvial deposits. The distribution of these units
is shown on the Geotechnical Maps, Plates 1 and 2.

4.2.2 Alluvium (Map Symbol Qal)
Alluvial soils are present in the stream channels and rivers, and
overlie the granitic bedrock The river crossing the site from
the southeast to the center - western boundry will contain the
most significant (locally deeper than 20 feet) amount of alluvial
sediments on the site. The alluvial soils should "consist of silty
fine to coarse sand, generally derived from the granitic bedrock.
The approximate geologic boundaries of alluvial sediments are
shown on the Geotechnical Maps, Plates 1 and 2.
4.2.3 Colluvium (Not Shown on Map)
Colluvial soils consist of surface deposits of slope washed
sediments The sediments are usually located at the base of
slopes and adjoin alluvial sediments. Colluvium generally
consists of a mixture of topsoils and weathered bedrock
materials. The thickness usually varies from a few feet
to the depth of adjacent alluvial soils.
4.3 Groundwater
Groundwater on the site will be primarily located in the alluvial
sediments of the major valleys Groundwater may also be located
in fractured granitic bedrock, however, the depth, quantity and
location are highly variable. Springs or seeps are likely to occur
in the steeper granitic terrain.
5.0 SEISMICITY
No active or potentially- active faults have been previously mapped
on the site. The nearest active faults capable of causing an
earthquake significant enough to effect the subject s.ite are
the Elsinore and San Jacinto fault zones, located 20 and 41 miles
east of the site, respectively

GEOTECHNICAL EVALUATION AND CONSTRAINTS

Upon completion of our geotechnical review, anticipated
conditions were analyzed with regard to proposed site de-
velopment. A discussion of constraints and possible mitiga-
tive measures follows.
Rippability
Seismic refraction traverses were conducted on the granitic
bedrock to estimate the relative rippabi -lity for potential
grading. Woodward - Gizienski and Associates performed 33
seismic traverses as a part of their report on the southern
portion of the site (see reference). We performed 5 seismic
traverses in the northern - central portion of the site.
Ripping estimates are based on Caterpillar Ripping Charts
utilizing a single shank D -9 bulldozer. Ripping effort and
depth might be increased using heavier equipment.
bE�
E�',
U
Rippability can generally be related to the topography The
steep boulder strewn slopes are usually marginally rippable or
non - rippable and may require blasting. The moderate slopes
and valleys are usually rippable to depths ranging from 10 to
20 feet.
The 5 seismic traverses located in the north - central portion of
the site indicated that area may be rippable to approximately
20 feet. The steep mountainous terrain surrounding the north-
,
central area is probably non - rippable to marginally rippable
in weathered areas.
Ripping estimates are based on Caterpillar Ripping Charts
utilizing a single shank D -9 bulldozer. Ripping effort and
depth might be increased using heavier equipment.

6.2 Oversize Rock and Fill Materials
Grading in hard rock terrain will generate large rock fragments
unsuitable for reuse in fills without special handling or process-
ing. The lack of soils on the higher elevation will result in
fill generated from cut areas being composed primarily of rock
fragments. Large rocks (to 4 -feet) may be disposed in canyon fills
deeper than 10 feet or in non - structural areas (open space):
Smaller rocks, less than 12 ", may be placed in compacted fill when
mixed with fill soils.
Blasting may be planned to generate smaller rock fragments if shot
points are closely spaced. Selective grading should be considered
where possible to retain soils for reuse in fills. Selective
grading would consist of stockpiling soils to allow mixing with
rock fragments.
6.3 Compressable Soil
Alluvial and coll.uvial deposits are generally unconsolidated and
will be susceptible to settlement under structural or fill loads.
Removal and recompaction of these materials is usually necessary.
The major drainage in the south - central portion of the site may
contain alluvial deposits that are too deep or saturated to remove
completely. Grading in these areas may require additional work such
as dewatering, or partial removal of the alluvium and surcharge fills.
6.4 Wastewater Disposal
If on -site sewage disposal is considered as an-alternative to a
city provided sewer, permiability and groundwater pollution will
need to be addressed. The granitic bedrock usually does not have
acceptable permiability for the various conditions of the building
sites, for a project of this size.

6.5 Trenches and Footings
Job No. 25045 -00
Log No. 3874
Page Seven
Cut lots and streets will probably expose materials that will be
difficult to impossible to trench with conventional equipment
Overshooting streets and pads and refilling to grade with
compacted fill will alleviate this condition.
6.6 Select Fill
Crushing of on -site rock could provide non - expansive select
material for reuse as fill. Crushed rock will provide an on -site
source for road base and trench bedding. Crushed rock would
also be suitable to be sold as a resource if grading will
produce an excess amount of material.
6.7 Land Use Planning
Because of the difficult grading conditions at the site, earthwork
costs may be greatly reduced by minimizing grading in.the non - rippable
areas and maximizing grading where earthwork will be less difficult.
6.8 Limitations
Our investigation was performed using the degree of care and skill
ordinarily exercised, under similar circumstances, by reputable
Soils Engineers and Geologists practicing in this or similar
localities. No other warranty, expressed or implied, is made as
to the conclusions and professional advice included in this report
Our conclusions, opinions and recommendations are based on a few
widely spaced seismic surveys. Conditions can vary widely between
test sites and material exposures. We believe, however, that the
findings summarized herein are representative of the site.

Attent i on Mr Lawrence Mal anfant
In accordance with your request we have made a preliminary engineering
geological study of the subject site, located north of Espola Road and
west of Old Coach Road in San Diego County, California The purpose
of our studies is to make a geological reconnaissance and preliminary
soil study of the subject site which would provide a basis for conclusions
and recommendations regarding the following
(1) Presence of possible geological and soil hazards on the site
(2) The suitability of the site for the proposed development
(3) An evaluation of the excavation characteristics of the subsurface
materials
(4) An evaluation of the relative stability of anticipated cut
and fill slopes.

In addition to these items preliminary foundation criteria regarding
allowable soil bearing pressures and pressures on retaining walls is presented
The results of our study indicate that there are no major adverse soil
1
or geologic conditions on the site which would preclude the further development
of plans for the subject project The site is underlain by granitic
rock of Cretaceous Age which is weathered and decomposed to varying depths
In general, our studies have indicated that with the exception of rock
outcrop areas, materials may be excavated by conventional heavy duty grading
equipment to depths of 10 feet and i:n selected places to depths of 20 feet
Locally, excavation may extend without blasting to depths of 30 feet
The materials expected to be excavated are generally suitable for purposes
of structural fill construction and slopes will have adequate factors
of safety against deep- seated failure to heights of up to 30 feet on
'
inclinations of 2 to 1 Cut slopes composes of granitic rock will be
similarly stable on inclinations of 1 -1/2 to 1 to heights of 50 feet
The attached report includes our conclusions and recommendations pertaining
to this site and the results of the field investigation and laboratory

Maximum cuts and fill slopes on the order of 50 and 30 ft, respectively,
are anticipated.
REVIEW OF AVAILABLE LITERATURE AND DATA ON FILE
Prior to starting field work on the subject site, a review
was made of available maps, geologic literature, aerial photographs,
and reports prepared by our firm on nearby projects having similar geologic
settings Topographic maps of the area were made available to our firm
by E F. Cook and Associates, Ltd , including three maps drawn to

The subject site encompasses approximately 685 acres in an
irregular shaped area measuring approximately 9,450 ft from north to
south and averaging approximately 3,100 ft from east to west in maximum
plan dimension In general the property lies between the Stoneridge
Development on the west and Old Coach Road on the east, and extends north
of Espola Road It is our understanding that tentative plans call for
the construction of both multiple unit condominium structures at certain
locations and single family residential lots bordering an 18 Hole Golf
Course Clubhouse and related facilities A preliminary development plan
prepared by Stephen G Oppenheim, AIA and Associates and dated September 10, 1973
indicates that the golf course will generally occupy the valley areas
with the condominium and apartment sites occupying the valley side slopes
and elevatEd hills and ridges The single family lots are generally
located on the side hill areas surrounding the condominium and apartment
development areas
It is our understanding that the proposed grading will generally
be nominal and will blend to the existing topography as much as possible.
Maximum cuts and fill slopes on the order of 50 and 30 ft, respectively,
are anticipated.

FIELD INVESTIGATION
The field work for this study was done during the period of
November 7 through November 23, 1973, under the supervision of a Project
Engineering Geologist from our firm Following a field geologic reconnaissance
of the site and surrounding area, refraction seismograph traverses and
test borings were made in representative areas Thirty -three seismograph
traverses, approximately 100 ft in length, were run with a Bison Model
1570B seismograph, and twenty -eight 6 -in diameter test borings, ranging
in depth from 2 to 43 ft, were made with a truck- mounted continuous flight
power auger A summary of the seismograph traverse results is found on
Table I Logs of the test borings were prepared by the geologist based on
our examination of the excavated material and the samples secured The Logs
of Test Borings found on Figs. 2 through 19 are based on examination of the

The soils encountered in the field were visually classified
in the laboratory and representative samples evaluated with respect
to strength, grain size, plasticity characteristics, dry density and
moisture content The classification was substantiated by the grain
size analyses and plasticity tests on the finer grained soils. The strength
of the soils was evaluated by means of soaked direct shear tests on both
relatively undisturbed and compacted samples and a consideration of
the density and moisture content of the samples, the penetration resistance
of the sampler, and the geologic characteristics of the formational soils
Fill tests, including soaked
suitability grain s -ize analyses,
remolded direct shear tests, and laboratory compaction tests, were performed
on samples of the probable predominant fill soils
The results of tests on relatively undisturbed samples are
found at the corresponding sample location on the Log of Test Borings The

southeastward from the Los Angeles Basin to the tip of Baja California
The property is situated in an area of crystalline igneous rock on the
western flanks of the - Peninsular Range, approximately two and one half
miles east, southeast of Battle Mountain and approximately 5 miles
northeast of Black Mountain (USGS Topographic Maps).
Topography and Surface Features
The major topographic features on the site consist of a series
of relatively high relief granitic peaks and a system of relatively steep
sided canyons which drain the property to the west Elevations across
the site range from below 420 ft in the main canyon bottom at the western
property line to over 975 ft (MSL) near a mountain peak at the northwest
corner of the property. Inclinations of the side slopes of the canyons
and ridges range from approximately 2 1 to 8 1, probably averaging about
4 1 overall The bottoms of the major canyons are relatively flat and
range in width from approximately 100 to 500 ft. Tributaries to these
major canyons are generally steep sloped and IT' shaped The entire
site is characterized by rock outcrops of, for the most part, irregular
size and shape Some of the outcrops indicated a certain lineation This
lineation appears to be major in the east west direction and minor in
the north south direction
At the time of our inspection., the surface of the site was
covered by vegetation consisting of a relatively sparse growth of native
chaparral and grasses Oak and a few sycamore trees and a relatively
dense growth of grasses covers the flat bottoms of the major canyons
and the tributaries at the lower elevations A few acres on the lower
hill slopes in the north central portion of the site have been used for

agricultural purposes
Man made structures observed on the property include a steel
water tank on a peak in the south central-part of the site, San Diego
Gas and Electric Company power lines, an aquaduct easement, and fencing,
roads and dirt trails which cross the property in various directions
There are also an abandoned orchard and farm house ruins in the northern
portion of the site An old cistern was noted in the area of the abandoned
farm house, however no hell was-noted. it ShoU',d ho antir�inated that an
N
old well exists in this area A septic leach may also be associated with
this area but was not located
Overburden and Lithology
In general, the soil mantle on the subject site consists of
topsoil, minor residual clay and colluvial soils underlying the peaks
and canyon side slopes and alluvium in the bottoms of the major canyons
Underlying these "overburden" soils is granitic rock of probable Cretaceous
Age which extends to significant depths on the site
The topsoil typically consists of 1 to 6 -1/2 ft of loose, dry,
porous silty sands with minor rock fragments which has an average thickness
on the order of 2 -1/2 ft. As indicated by one of the borings and an
examination of road cuts in the area, a patchy irregular clayey zone
exists in places between the topsoil and the underlying decomposed rock
These "residual" clays appear to be somewhat expansive in nature, but
are relatively limited in extent. On the lower slopes, the topsoil and
rock fragments have accumulated under the influence of gravity and form a
colluvium deposit which extends to depths on the order of 10 ft. In the
bottoms of the larger valleys, alluvial soils consist of silty sand with

1 gravels which in one of the borings, reached a thickness of 26 ft. Other
' WOODWARD GIZIENSKI & ASSOCIATES
CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGISTS
borings in the alluvium did not reach the underlying rock
Underlying
the overburden soils are granitic rocks which are
decomposed and weathered to varying depths Refusal to drVI ing equipment
was generally reached at depths ranging from 2 ft to 35 -1/2 ft One
boring reached a depth of 43 ft without refusal. Hard rock underlies
the decomposed rock at depth and consists primarily of coarse crystalline
quartz diorite and granodiorite Outcrops in portions of the north central
parts of the site appear to be finer grained gabbroic rocks, some of
which exhibit a slight schistosity
Geologic Structure
Geologic structural features such as joints, fractures, bedding
attitude, faults and landslide features comprise this section. In general,
the granitic rocks are massive and exhibit no bedding The dominant
strike and dip (the strike is defined as the direction of a level line
' WOODWARD GIZIENSKI & ASSOCIATES
CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGISTS
in the joint plane, the dip is defined as the angle from the horizontal
of a line on the joint plane perpendicular to the strike) of systematic joints
and fractures is north - northwest to south - southeast and east to west
both with near vertical dips. These trends are evident in exposures
in road cuts and are emphasized by numerous veins, dikes and other intrusive
bodies of light colored fine grained material (probably apiite) which has
intruded along the fracture and joint partings
Our geological reconnaissance of the site and the review of
the available topographic and geologic maps did not reveal the presence
of landslides on the site. Further study, including a review of current
published data relating to known mapped faults in the general area, reveals
no major faults on or adjacent to the site

CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGISTS
Project No 73 -269 Page 7
Groundwater
No groundwater was encountered in any of the test borings above
the valley bottoms at the time of drilling No marshy areas, springs or
water seeps were noted during our reconnaissance of the site. Groundwater
was encountered in the borings below the mayor canyon bottoms at depths
tranging from,9 to 16 ft at time of drilling
DISCUSSION - SITE DEVELOPMENT
From a soil and geologic standpoint a discussion of the suitability
WOODWARD GIZIENSKI & ASSOCIATES
CONSULTING SOIL AND FOUNOATION ENGINEERS AND GEOLOGISTS
of the site for the proposed development should include
(A) The presence of geologic hazards such as faults,
shear zones or existing landslides
(6) The treatment of potentially compressible overburden
soils such as topsoils, alluvium and colluvium.
(C) The presence and effect of potentially expansive
soils (clayey soils)
t(D)
The stability of proposed cut and fill slopes
(E) The excavation characteristics of the geologic
formations, and the handling of oversized rock materials
In regard to the first 4 items outlined above, our study has
revealed no major adverse problems The potentially compressible soils
such as topsoil and colluvium which may exist in fill foundations and
building areas, can be excavated.and recompacted during grading prior
tto
placing structures. Expansive residual clay soils appear to be very
minor in occurrence and there should be no trouble in replacing these
(if they occur at finish grade) with nonexpansive granular materials
which should be available in sufficient quantities in cut areas The

materials expected to be used in fills, the decomposed granitic rock,
will be suitable for fill and slope construction and should be stable
in cut slopes to moderate heights
The major criteria, from design as well as grading standpoint,
consist of the excavation characteristics of the underlying rock formations
WOODWARD GIZPENSKI 8 ASSOCIATES
CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGIS S
In order to provide a basis for rippability guidelines, we have considered
the following criteria
(1) The presence and nature of existing rock outcrops
(2) Refusal to boring with drilling equipment
(3) Seismic wave velocity of the rock
(4) Our experience with similar materials in adjacent areas
The presence of large rock outcrops in most cases indicate
surface blasting Some of the smaller outcrops, however, may be "float"
rock which has moved down slope from higher elevations and become embedded
in the topsoil or col'luvium or may be a "boulder of decomposition" surrounded
by ripplble material It is sometimes difficult to distingu=ish between
the different types of outcrops. At the site some of the outcrops appear
to be dikes of intrusive material and these appear to be quite fractured,
it may be possible to excavate these materials with heavy duty single shank
ripping equipment and skilled operators; however, it may be time consuming
and large amounts of oversized rock will probably be generated
Our experience has shown that refusal to drilling with the
equipment used in investigation generally indicates that blasting will
be required at that depth in the particular area.of drilling, however,
q p
it should be noted that refusal to drilling could be experienced on the
top of a large boulder of decomposition as well as "rooted" hard rock
For seismic wave velocities, we have developed general guidelines
WOODWARD GIZPENSKI 8 ASSOCIATES
CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGIS S
�1
n
Project No 73 -269 Page 9
for the types of rock at the site. Rock with seismic wave velocities
up to 5,000 feet per second can generally be excavated by heavy duty
excavating equipment Seismic wave velocities between 5,000 and 6,000
feet per second constitute borderline material, the excavation of which,
depends on the fracturing of the rock, the condition of the equipment, and
the skill of the operator Rock material with velocities greater than
6,000 feet per second generally requires blasting prior to excavation
A corollary criterion to rippability is the handling of over
sized rock materials generated by the rock excavation Rock materials
may be handled generally in four ways
(1) Oversized pieces (rock greater than 2 ft in size
is considered oversized) may be collected and disposed of off site.,
(2) Rock up to certain sizes may be properly placed in
compacted fills in predesignated areas in accordance with specifications,
(3) A properly constructed rock fill incorporating
rock to rock contact could be built, however, these fills are generally
considered nonstructural in nature, or,
(4) The rocks may be used for decorating purposes.
In general, rocks up to 2 ft in size may be used in any fill
up to within 4 ft of grade or depth of utilities, whichever is greater,
provided they are properly placed and compacted around with fines Rocks
up to 4 ft in size may be used in special areas such as in golf course
fills and other non structural areas, in slope areas and below streets.
Problems with pure rock fills include difficulties in controlling construction
and piping of soil down between the rock interstices if sufficient cover
over the rock fill is not provided

SUMMARY OF FINDINGS
(1) Our studies have revealed no adverse geologic hazards on the
site such as faults, landslides, weak formational units or adverse jointings
on bedding. No evidence of groundwater at significant depth was noted in
areas above the major valley bottom. Groundwater was encountered in the major
valley alluvium at depths rang ng from 9 to 16 ft No mineral resources are
indicated however the granitic rock could be a source of base material but
this would require further study
(2) Based on the results of our studies it is our opinion
that there are no major adverse soil or geologic conditions on the site
which would preclude the further development of plans for the subject
project. There is, however, a limit to which excavation can extend without
blasting and this should be considered in design. There are also porous
potentially compressible overburden soils which will require treatment prior
to.placing fills on structures
WOODWARD GIZIENSKI At ASSOCIATES
CONSULTING SOIL AND FOUNDATION ENGINEERS AND GEOLOGISTS
(3) The subsurface soils and geologic formations consist of
an overburden of topsoil, patchy residual clay, colluvium on the lower
slopes and alluvium underlying the bottoms of the major canyons, all of
which are underlain by granitic rock of probable Cretaceous Age, which
is decomposed to various depths
The topsoil, colluvial and alluvial soils. are considered potentially
compressible and will require excavation and compaction in areas where
fills or structures are proposed Clay soils are anticipated only locally
and are not expected'to present a great problem.
(4) In general it is our opinion that the granitic rocks on
site can be excavated to depths ranging from 10 to 30 ft except in the
area of large rock outcrops

RECOMMENDATIONS
(1) In areas that will be graded for use as building pads, it
is recommended that all porous surface soils be excavated, replaced and
recompacted prior to placing fill or foundations The maximum depth
of these soils is anticipated to be on the order of 10 ft, however the
actual depth of excavation and compaction should be controlled in the
field at the time of grading when the soils are exposed

a minimum depth and width of 12 in The pressures may be increased by
one-third for loads that include wind or seismic forces.
It should be noted that San Diego County minimum requirements
consist of an 18 in deep 1-5 in wide footing for two -story structures.
In order to, resist lateral forces it is recommended that friction
between the bottom of the footing and the underlying soil be used. A friction
value of 45 may be utilized in designs, with a suggested factor of safety
of 1.5
Retaining walls not restrained from movement at the top and
having a level backfill surface may be designed for pressures exerted
by an allowable equivalent fluid weight of 35 pcf.

SPECIFICATIONS FOR CONTROLLED FILL
I GENERAL
These specifications cover preparation of existing surfaces to receive fills,
the tvpe of soil suitable for use in fills, the control of compaction and the
methods of testing compacted fills. It shall be the Contractor's responsibility;
to place, spread, water and compact the fill in strict accordance with these
specifications. A Soil Engineer shall be the Owner's representative to inspect
the construction of fills Excavation and the placing of fill shall be under
the direct inspection of the Soil Engineer, and he shall give written notice
of conformance with the specifications upon completion of grading Deviations
from these specifications will be permitted only upon written authorization
from the Soil Engineer A soil investigation has been made for this project,
any recolumendations made in the report of the soil investigation or subsequent
reports shall become an addendum to these specifications '
II SCOPE
The placement of controlled fill by the Contractor shall include all clearing
and grubbing, removal of existing unsatisfactory material,, preparation of the
areas to be filled, spreading and compaction of fill in the areas to be filled,
and all other work necessary to complete the grading-of the filled areas
III MATERIALS
1 Materials for compacted fill shall consist of any material imported or
excavated from the cut areas that, in the opinion of the Soil Engineer, is
suitable for use in constructing fills The material shall contain no rocks
or hard lumps greater than 24 inches in size and shall contain at least 40
of material smaller than 1/4 inch in size. (Materials greater than 6 inches
in size shall be placed by the Contractor so that they are surrounded by com-
pacted fines, no nesting of rocks shall be permitted.) No material of a perish-
able, spongy, or otherwise of an improper nature shall be used in filling.
2. Material placed within 24 inches of rough grade shall be select material
that contains no rocks or hard lumps greater than 6 inches 'in size and that
swells less than 3 when compacted as hereinafter specified for compacted
fill and when subjected to an axial pressure of 160 psf.
3. Representative samples of material to be used for fill.shall be tested
in the laboratory by the Soil Engineer in order to determine the maximum -
density, optimum moisture content and classification of the soil. In addition,
the Soil Engineer shall deter-mine the approximate bearing value of a recom
pacted, saturated sample by direct shear tests or other tests applicable to
the particular soil.
4. During grading operations, soil types other than those analyzed in the
report of the soil investigation may be encountered by the Contractor. The
Soil Engineer shall be consulted to determine the suitability of these soils.

COMPACTED FILLS
1. General
Attachment I
page 2 of 4
(a) Unless otherwise specified, fill material shall be compacted by the
Contractor while at a moisture content near the optimum moisture content
and to a density that is not less than 90 of the maximum.density deter-
mined in accordance with ASTM Test No. D1557 -70T, or other density methods
that will obtain equivalent results.
(b) Potentially expansive soils may be used in fills below a depth of
24 inches and shall be compacted at a moisture content greater than the
optimum moisture content for the material.
2. Clearino and Preparing Areas to be Filled
(a) All trees, brush, grass, and other objectionable material shall be
collected, piled and burned or otherwise disposed of by the Contractor
so as to leave the areas that have been cleared with.a neat and finished
appearance free from unsightly debris.
(b) All vegetable matter and objectionable material shall be removed by
the Contractor from the surface upon which the fill is to be placed and
any loose and porous soils shall be removed or compacted to the depth
shown on the plans unless otherwise specified in writing by the Soil
Engineer The surface-shall than be plowed or scarified to a minimum
depth of 6 inches until the surface is free from uneven features that
would tend to prevent- uniform _compaction by the equipment to be used.
(c) Where fills are constructed on hillsides or slopes, the slope or
of the
original ground on which the fill is to be placed shall be stepped
keyed by the Contractor as shown on the attached Figure. The steps shall
extend completely through the soil mantle and into the underlying for -
mation materials.
(d) After the foundation for the fill has been cleared., plowed or scari-
fied, it shall be disced or bladed by the Contractor until it is uniform
and free from large clods, brought to the proper moisture content and com-
pacted as specified for fill
. 3. Placing, Spreading, and Compacting Fill Material
(a) The fill material shall be placed by the Contractor in layers that
when compacted shall not exceed 6 inches Each layer shall be spread
evenly and shall be thoroughly mixed during the spreading to obtain uni-
formity of material in each layer.
(b) When the moisture content of the fill material is below that speci-
fied by the Soil Engineer, water shall be added by the Contractor until
the moisture content is as specified.
(c) When the moisture content of the fill material is above that speci=
fied by the Soil Engineer, the fill material shall be aerated by the Con-
tractor by blading, mixing, or other satisfactory methods until the moisture
content is as specified.

(d) After each layer has been placed, mixed and spread evenly, it shall
be thoroughly compacted by the Contractor to the specified density. Com-
paction shall be accomplished by sheepsfoot rollers, vibratory rollers,
multiple -wheel pneumatic -tired rollers or other types of acceptable com-
pacting equipment Equipm ,_nt shall be of such design that it will be able
' to compact the fill to the specified density. Compaction shall be con-
tinuous over the entire area and the equipment shall make sufficient trips
to insure that the desired density has been obtained.
(e) Surface of fill slopes shall be compacted so that the slopes are
stable and there shall be no excessive loose soil on the slopes.
INSPECTION
1. Observation and compaction tests shall be made by the Soil Engineer during
the filling and compacting operations so that he can state his opinion that the
fill was constructed in accordance with the specifications.
2. The Soil Engineer shall make field density tests in accordance with ASTM
Test No. D1556 -64T Density tests shall be made in the compacted materials
beloly the surface v%,here the surface is disturbed When these tests indicate
that the density of any layer of fill or portion thereof is below the speci-
fied density, the particular layer or portion shall be reworked until the
specified density has been obtained.

PROTECTION OF WORK
1. Durinq construction the Contractor shall properly grade all excavated
surfaces to provide positive drainage and prevent ponding of water. He shall
control surface water to avoid damage to adjoining properties or to finished
work on the site. The Contractor shall take remedial measures to prevent
erosion of freshly graded areas and until such time as permanent drainage
and erosion control features have been installed.
2. After completion of grading and the Soil Engineer has finished his obser-
vation of the work, no further excavation of filling shall be done except under
the observation of the Soil Engineer.

nt.
The project area or portions of the project area have
been the subject of several biological inventories from
which reports have been generated. The E.F. Cook and
Associates (1973) report was the most comprehensive in terms
of subject areas covered, although their survey was not
entirely coincident with this site. It dealt with
terrestrial vegetation, flora, and fauna and it was
performed by a team of biologists which, considering the
nascent stave of the environmental review process, were
unusually well skilled and provided very thorough and
relevant information. The team consisted of Dr. James
fienrickson, Dr. Gerald Collier, and Dr. Ross Dingman, Julian
Lee and Peter V. August. One of the most significant
revelations of the report is that the ornithologists sighted
a number of Least Bell's Vireos on the site during their
survey. ;-Missing from this report are a habitat map,
acreages of vegetation types, lack of information on Black -
tailed Gnatcatchers, Artemisia Palmeri and other sensitive
plants. The report is out of date relative to sensitive
species designations, which proliferated mostly in the years
subsequent to their work. The LISA, Inc. (1981) report was

The lowest point (approximately 400 feet above MSL) occurs
in the northwestern corner of the property (I:). Large
boulders are common throughout the site, particularly on
steep slopes as at the northeast and east - central parts of
the property. A major northwest- southeast oriented drainage
system (1) is present in thelsouthern part of the site, with
several minor tributaries. This drainage system, which runs
through Green Valley and continues off -site to the east
toward its headwaters, is perennially wet and supports well -
developed woodland habitat. A smaller drainage system
transects the northern part of the property (3), but lacks
the well - developed woodland habitat found to the south. A
washed -out dam occurs at the northwest end of this drainage
(J). Most minor drainages on -site were dry at the time of
survey, although surface water was present in the north -
south oriented drainage along the east - central boundary of
the property (2), and in some of the drainages in the
northern portion of the property (4).

ion and Flora
Although it is possible to recognize and map numerous
vegetation types and stands of vegetation on this site, 3
types have been identified for use in this discussion (see
Vegetation map). The most albundant type is Coastal Sage
Scrub, a low, brushy plant community. A "field" habitat
resulting from past disturbance, and wooded areas along the
streams are about equal in coverage. Chaparral and natural
grassland are rare on this site.
Coastal Sage Scrub covers about 1076 acres or 85.8% of
the site. Dominant species are California Sagebrush
(Artemisia californica), Flat -top Buckwheat (Eriogonum
fasciculatum) and Laurel Sumac (Rhus laurina). Coastal Sage
Scrub in the northern part of the property is additionally
characterized by the presence of White Sage (Salvia liana)
which, in a few locations, forms almost monotypic stands or
at least is clearly the dominant component of the
DJ11
jThe margins of the two stream systems in the southern
part of the property contain dense gallery forests dominated
by Coast Live Oak (Quercus agrifolia). Black willow (Salix
gooddingii) locally forms groves among the oaks, and many,
very large Western Sycamores (Platanus racemosa) contribute
to the overstory. A very dense, diverse understory is
characterized by numerous native shrubs including
(primarily) Poison -Oak (Toxicodendron diversilobum), but
vegetation. On the southern exposure in the southwestern
corner of the northern part of the site (N), species typical
of drier habitats are present, such as Odora (Porophyllum
gracile) and Alderson's Rush rose (Helianthemum sconarium
var. aldersonii). Throughout the property, Coastal Sage
Scrub exists o-n all slope exposures, and shows evidence of
almost no disturbance in some areas, and heavy disturbance
in others. The least disturbed vegetation is on the steep
east and north- facing slopes along Old Coach Road and above
the stream (C), as well as most of the northern part of the
property. The plant cover in the central part of the site
(E) is lower, has a sparser shrub coverage, and has more
introduced species in the vegetation. Some areas have
recently burned and are in a state of natural recovery (F).
Where is disturbed, by dry
the property most apparently
farming in the flatter part of the central portion of the
site (E), Coastal Sage Scrub has been converted to a
disturbed grassland -like habitat dominated by introduced,
weedy annuals such as Red -Stem Filaree (Erodium cicutarium),
Black Mustard (Brassica geniculata), Red Maids (Calandrinia
ciliata) and non- native, annual grasses. Disturbed habitat
types, including roads, cover about 80 acres or 6.4Z of the
site.
Three types of arborescent vegetation (trees) occur on
the property. Although they mace up only abou.t 67 of the
cover, the woodlands are visually and biologically dominant.
Riparian Woodland covers about 25 acres, Southern Oak
Woodland covers about 48 acres, and Eucalyptus Woodland
covers about 2.9 acres. Additionally, a small area mapped
as Riparian Scrub occurs in the northern part of the
1
property.
Riparian woodland and Southern Oak woodland occur side -
1
by -side in the southern part of the property, ecologically
separated by a moisture gradient along the slope.
"Riparian," meaning literally "streamside," includes the
habitat under direct influence of the stream. It was mapped
as the stream bed proper, or any area where the vegetation
is characterized by hydrophytes. (In addition, there are
about 2 acres of unvegetated or disturbed riparian habitat
on both sides of the Old Coach Road crossing). Southern Oak
Woodland, -by contrast, is located upslope of the immediate
stream bed area, and is a drier habitat.
jThe margins of the two stream systems in the southern
part of the property contain dense gallery forests dominated
by Coast Live Oak (Quercus agrifolia). Black willow (Salix
gooddingii) locally forms groves among the oaks, and many,
very large Western Sycamores (Platanus racemosa) contribute
to the overstory. A very dense, diverse understory is

In the northern part oflthe property, Riparian habitat
is not particularly well - developed. Arborescent vegetation
is composed almost entirely of 1111ule -fat (Baccharis
glutinosa) and Arroyo Willow (Salix lasiolepis), with
willows being common only in the vicinity of the old. dam.
Understory vegetation includes Giant Ryegrass (Elvmus
condensatus), Many - flowered Figwort (Scrophularia
californica) and Curly Dock (R.umex crispus). Although some
oaxs are present near the dam, this vegetation type lacks
the large trees and complex canopy structure characteristic
of riparian habitat to the south.
Riparian Scrub, composed almost primarily of ,1ule -fat,
also occurs in the northern part of the property, and
accounts for 3.1 acres or 0.3% of the cover on -site. This
habitat occurs in drier locations than Riparian Woodland
Southern Oak Woodland is represented throughout the
northern part of the property by individual oak trees or
small stands of oaks, but is best developed in the western
part of this area, particularly on the western slope of the
large, southwestern ridge (north A). Here, groves typically
consist of many large, mature trees along with a well -
developed understory typical of such woodlands. Three
species of oak are present in the area. Coast Live Oak
(liuercus agrifolia), Lngelmann's Oak (Ouercus engelmannii)
and Scrub Oak ( uercus dumosa).

that Engelmann Oak can also occur as a component of Coast

Scrub Oak is not common in the northern part of t'he
property, and usually occurs in drier areas than the other
two oak species, such as on eastern or southern exposures,
or in association with Chaparral.
One large Eucalyptus grove occurs on -site, in the
south - central portion of t* northern part of the property.
This grove is composed of mature trees to about 20 -25 meters
in height. The primary species is Blue Gum (Eucalyptus
globulus). The understory of Eucalyptus Woodland is
generally poorly developed due to a combination of factors
which act to inhibit plant growth, including the
accumulation of large amounts of leaf litter and the
allelopathic (toxic) effect of the leaves, which result in
1
sterile soil conditions. Although elements of Coastal Sage
Scrub such as Lemonadeoerry (Rhus integrifolia) and Spiny
Redberry (Rhamnus crocea) are present in low numbers, the
understory is composed primarily of weedy species from the
adjacent, disturbed grassland -like habitat.
Chaparral, dominated by Chamise (Adenos.toma
fasciculatum) and Scrub Oak ( uercus dumosa), occurs in the
southeastern corner of the site (D), where it covers about
12 acres, and in a small area in the southwestern portion of
the northern part of the site (0), where it covers 4 acres.
Chaparral may also occur .as occasional, small stands in some
of the northern ravines. This is a dense brush vegetation
about 1.5 to 2 meters tall. It appears to be relatively low
in plant species diversity. Overall, Chaparral covers 16
acres or about 1.30 of the property.
A small, native grassland (about 0.8 acre) dominated by
Western Ragweed (Ambrosia psilostachya var, californica) and
other perennial herbs occurs between Southern Oak Woodland
and Riparian Woodland in the southern part of the property.
Small areas of native grassland (0.9 acre) also occur in the
northern part of the site, where the dominant species is
Giant Stipa (Stipa coronata)j Illative grassland accounts for
0.1% of the cover on -site. I
Dr. James Flenrickson, in E.F. Cook (1973), repor.ted 171
vascular plant species, 34 (200) of which were introduced,
naturalized species. The more recent survey added 62 plant
species to the list, some of them important to the
environmental process, such as Caulanthus stenocarous,
Artemisia Palmeri, Haplopappus palm,eri ssp. palrneri and
Haplopanous._junceus. The total recorded flora of 233
species is a large number which indicates the diversity of
habitats and the low level of disturbance, which in turn
promotes the retention of many native species. Past
t
disturbances, primarily including
agriculture, have promoted
non - native plant species at
the expense of coverage by
natives, but it may not have
I resulted in the extirpation of
any native species from the
site.
Wildlife Habitat
The wildlife habitat o0his
property can only
accurately be considered in
the context of the region. The
habitat value is affected byithe
proximitv of human
activities and land uses (such
as the change from shrublands
to golf courses and houses), by the proximity and quality of
adjacent natural areas, and by the intrinsic nature and
quality of the on -site resources. The property is composed
of several high - quality habitat types which lie literally at
the urban -rural interface. Habitat to the west is mostly
intensively developed, and it is rapidly developing toward
the southwest, whereas in all other directions low levels of
development allow for free movement of wildlife and
retention of important amounts of habitat. The upper end of
Lake Hodges and agricultural open space in San Pasqual
Valley is connected to the site via Green Valley and steep,
brush - covered slopes. To the
east lie steep, rocky and
brushy slopes and canyons.
The brushland vegetation quality in the central part of
the site (E) is relatively low, given apparent past
disturbance which probably affects the carrying capacity of
the habitat. However, this part of the site exhibits
numerous rock outcrops, some Iof which are quite large, and
ravines which are useful to wildlife, particularly reptiles
and small mammals. Ravines in this area, and elsewhere on
the property, provide valuable connections to similar tracts
of habitat off -site. The brushy areas along Old Coach Road
and Espola Road (B), in the southern part of the site,
although somewhat disturbed in places, are of high value to
wildlife. Of particular value is habitat for several pairs
of Black- tailed Gnatcatcher,
I and the proximity of the scrub
to the riparian corridor. Brushland in the northern part of
the site is largely undisturbed. Certain areas are of
particularly high value to Black- tailed Gnatcatchers and
other bird species of concern, due largely to a combination
of topography and vegetation
structure.
Disturbed grasslands probably
are of relatively low
value to wildlife, particularly since these areas receive
off -road vehicle and shooting usage. They do serve as
foraging area for birds of prey, which as a group is
composed of sensitive animals.
The most valuable habitats on the site are the Riparian
6,ioodlands and Southern Oak Noodlands associated with the
principal streams. In the southern part of the site, these
habitats are truly exemplary
in their natural character, it

is remarkable to find such high- quality, relatively
undisturbed habitats this near the coast.. These woodlands
are valuable to wildlife since they provide essential
habitat for certain species (i.e., Bell's Vireo), and
because they are highly productive in terms of the number of
individual animals they can support. Woodlands elsewhere
on -site also provide valuable habitat for certain species of
wildlife, nowhere are they as well - developed as along the
major stream in the southern part of the property (1),
however. Riparian habitat in the northern part of the site
is not expected to support Least Bell's Vireos, for example,
due to its small size and unsuitable canopy structure for
that species.
Woodlands on -site are valuable for other reasons,
including their "regulatory" status as habitat for the
endangered Bell's Vireo, birds of prey and other sensitive
species, but are particularly valuable when considered at
the ecosystem level. Coastal habitats in general are
declining, among them Coastal Sage Scrub (70° reduced from
its primeval extent in San Diego County) and Riparian and
Oak i,,00dlands. While Coastal Sage Scrub is still relatively
abundant although increasingly threatened by urbanization,
riparian habitats are already at extremely low levels and
are mostly quite disturbed where they still exist (Riparian
',Ioodland constitutes less than 0.5% of the County area)
SENSITIVE SPECIES - Plants
Five sensitive plant species were found on the site.
One of these species is considered rare by the State of
California. Although none of the other species are
considered rare or endangered by the State of California or
the United States Fish and Wildlife Service, all are subject
to consideration in the environmental review process, and
could affect a determination of significance by the lead
agency. In addition, Chorizanthe seedlings potentially
ascribable to another sensitive species were detected.
Caulanthus stenocarpus (Slender -pod Caulanthus) is a
candidate for' Federal listing (C2), listed as rare by tze
State of California, and on List 1 of the California dative
Plant Society's Inventory oflRare and Endangered Vascular
Plants of California with a P, -E -D rating'of 2 -2 -2 (Smith and
York 1984). Slender -pod Caulanthus is a small annual which
occurs on dry slopes, particularly on burns, in San Diego
County and northern Baja California (Munz 1974, t- 7iggins
1980). The species is endangered in a portion of its range
and rare outside California (Smith and York 1984). Slender -
pod Caulanthus is difficult to distinguish from the more
common, closely - related taxon, Streptanthus heterophyllus
(placed in the genus Caulanthus in some treatments).
Specimens collected during this survey appear intermediate
between the two taxa with respect to many morphological

characters. Final determination of this taxon was based on
certain key characters which Iindicate that these specimens
are best ascribable to Caulanthus stenocarpus. While
recognizing the rarity of Caulanthus stenocarpus in San
Diego County, it should also be pointed out that the type
locality for this species is Bernardo.
Slender -pod Caulanthus was found in two places on -site,
and in both cases was exceedingly rare, with only 2
individuals observed in each location. The small population
size on -site and its occurrence in seemingly undevelopable
areas reduce the probable threats to this species
Artemisia palmeri or Palmer's Sagebrush (CLAPS List 2,
R -E -D Code 1 -1 -1, no State or Federal status). This plant
is a tall, weak shrub with inconspicuous flowers. It occurs
in riparian and other mesic habitats of San Diego County anc_
northwestern Baja Californial, Mexico (Wiggins 1980). It was
found almost the entire length of the stream through Green
Valley (1), where it is a common plant at the edges of the
riparian habitat. The on -site population is very large and
should be considered significant. Of possible scientific
interest is the presence of several hybrid individuals of
Artemisia palmeri X Artemisia douglasiana east of the
junction of Old Coach Road and Old Coach [-lay.
Chorizanthe procumbens war. albiflora or Fallbrook
Spine-flower (GIPS List 4, R -E -D Code 1 -1 -3, no State or
Federal status). This annual plant was found by the E F.
Cook team. Henrickson (with E. F. Cook) did not indicate
the species as sensitive, since the report was prior to the
first edition of the CNPS Inventory (Powell 197-), and he
therefore did not comment onlits distribution.
Several Chorizanthe see'dlinas were observed in tine
northern part of the property. A number of Chorizanthe
species are potentially occurring in the area, Chorizanthe
procumbens var. albiflora isIdistinguishable to varietal
level only when in flower, so a positive identification
could not be made during this survey. If this taxon is
Fallbrook Spineflower, its population would probably not be
considered significant unless it occurred in large
quantities. Nevertheless, Chorizanthe seedlings were
observed only in one location, near the northwestern
boundary (0) near the pine t.ree nursery. This plant should
be searched for in spring, since fresh flowers are needed
for proper identification.
Haplopappus junceus or 1Rush -like Bristleweed (CLAPS List
2, R -E -D Code 1 -1 -1). This weak, inconspicuous shrub was
found in one location west of Old Coach Road, near the fire
station. It probably occursielsewhere on the site and could
be common. It would probably not be considered' significant.

Haplopappus palmeri ssp1
nalmeri (listed as Ericameria
p. ssp. p. by CLAPS) or Palmer's
Ericameria (CLAPS List 2, R-
E-D Code 2 -2 -1, no State or
Federal status). This plant is
a robust shrub with very small,
yellow flowers. It grows in
southern San Diego County and
northwestern Baja California,
therefore within the U.S. it
is limited to San Diego County.
In San Diego County it is rare,
with probably fewer than 10
known populations in places
such as Jamaeha, Sinning Hills,
and Adobe Falls. It was found in two locations on -site and
is considered significant. A total of about 15 plants were
found.
Animals
r
The earlier surveys by E.F. Cook, PISA, PRC TouDs and
Wier had limitations of scope, intensity or season which
prevents at this time a comprehensive, precise evaluation of
sensitive animal species. However, from these reports and
an understanding of similar sites, some conclusions can be
made.
There are numerous sensitive animal species either
known to occur on the site or which are highly likely to
occur there. This includes species of various levels of
sensitivity, including one which is "endangered." The
potentially most - constraining wildlife species from a
regulatory standpoint is thelLeast Bell's Vireo (Vireo
bellii pusillus). This species is listed as "endangered" by
the State of California and is proposed for "endangered"
status with the federal government (U.S. Fish and wildlife
Service).
The Least Bell's Vireo Baas observed on the site in 1973
by the E.F. Cook team. A total of 7 birds were observed,
with adults seen feeding fledglings. In our opinion, it
seems unlikely that any habitat changes which have occurred
in the last 13 years would be responsible for potential
cessation of site usage by this species. This opinion
cannot be confirmed until spring (April -July) because the
bird is highly migratory, spending only spring and summer in
this area.
The habitat on -site is not typical for Bell's Vireos in
San Diego County. Generally! they are found in dense,
willow- dominated habitat such as along the larger rivers.
Recently, however, with morelsurveys
being conducted on
smaller streams, the species
is being detected in habitat
areas similar to this. The nearest
known, substantial Least
Bell's Vireo population is at the upper end of San Pasqual
Vallev at the Highway 788 bridge.
The Least Bell's Vireo was proposed for endangered
st.atus last IMay by the federal government which cited its
greatly reduced range and population size, nest parasitism

The Black— tailed Gnatcatcher is a tiny gray songbird
(half the size of a sparrow) which is permanently resident

Scrub. It is found only in northwestern Baia California and
coastal southern California, and it is estimated there are
fewer than 1000 pairs in the U.S. (Atwood 1930). Its
distribution is largely coincident with urbanizing areas,
and its range has been reduced in proportion to the loss of
Coastal Sage Scrub. Its locall distribution includes much of
the undeveloped parts of the City of Poway, lending a
perception in this area that it is indeed not a "rare" bird

local perception of this species' endangerment is
understandable, yet incorrect when one considers the
Datterns and projections for urban and agricultural growth
superimposed upon the distribution of the Black— tailed
Gnatcatcher throughout southelrn California.
On the property, there are several pairs on both the
northern and southern parts. The northern part has at least
6 pairs and the south has at least 7 pairs. The total,

potential number is probably on the order of 15 -20 pairs,
which could be found throughout Coastal Sage Scrub here.
This amount of gnatcatcher habitat would be considered
significant. Good information on the locations of nesting
pairs is essential to the determination of impacts and as an
input to good planning.
Among numerous sensitive bird species that have been
observed on -site are the birds of prey Turkey Vulture
(Cathartes aura), Black- shouldered Kite (Elanus caerulea),
Northern Harrier (Circus cyaneus), Cooper's Hawk (Accipter
cooperi), Red - shouldered Hawk (Buteo lineatus), Red- tailed
Hawk (Buteo jamaicensis), American Kestrel (Falco
sparverius) and Golden Eagle (Aquila chrysaetos). Golden
Eagle nests (both active and historic) are known from
Crane's Peak, Starvation Mountain and Bandy Canyon (Thomas
A. Scott, personal communication), and the site is surely
part of t'he foraging area of these animals. Two Golden
Eagles were observed flying over and successfully foraging
on the northern part of the site, and perched on Crane's
Peak, where they may nest.
The property and environs are suitable foraging habitat
for all of the above mentioned birds of prey, plus at least
four species of owl (Screech Barn, .Long -eared and Great
Horned), and other hawk species (Merlin, Peregrine Falcon,
Prairie Falcon and Sharp- shinned Hawk).
Suitable nesting habitat exists for many of the bird of
prey species mentioned. As an example of coastal - foothill
riparian habitat, and a nesting resource for birds of nrev,
the property and its environs are exceptional. Nests of the
following species have been observed, or are likely Red -
tailed Hawk, Red - shouldered Mawk, American Kestrel, Black -
shouldered Kite, Cooper's Hawk, Screech Owl, Barn Owl, Great
Horned Owl. Nesting by Golden Eagle is very unlikely.
Two other bird species of concern occur on the site
Sage Sparrow (Amphispiza belli) and Rufous - crowned Sparrov
(Aimophila ruficeps lambi). (Both species are found in

approximately 150 acres of habitat in the southern part of
the property, a like amount in the north, and the stream
area would probably conserve most or all of these species.
No mammal species listed as sensitive are expected on
the site, however some species of high public interest
probably do occur. These would include Bobcat (Felis

(Odocoileus hemionus), Badger (Taxidea ta:us), Long — tailed

These animals, being large, more visible and better known,
are noticed by the public despite their non - sensitive
status. Their presence would be indicative of good 'habitat
quality.

to be the minimum
carrying capacity for one pair of Gnatcatchers (Atwood
1980), and be designed to accompany the largest density of
Black- tailed Gnatcatchers possible. Some effort should also
be made to include known locations of Sa,,e Sparrows and
Rufous- crowned Sparrows within or near this preserve.
3. Concentrate developments

5. Conserve as many as possible of the oak groves (or other

6. Landscaping should be done with non - invasive exotic

RECOHMENDATIO dS FOR FUTURE STUDY
1. Census between late April and late May for Least Bell's

2. Census in April and May for nest locations of Black-

picture of important habitat for these animals.
3. Identify precisely wetland habitats that would be under
jurisdiction of the Army Corps of Engineers and the
California Department of Fish and Game.
4. Identify nest locations of birds of prey throughout the
project area. It is also advisable to determine the recent
and current status of nearbylGolden Eagle pairs.
5. Survey suitable areas in the northeast and east- central
portion of the property between April and June for the
presence of the sensitive plant species Chorizanthe
procumbens var. albiflor.a. This survey would be
particularly important if these areas will be disturbed by
any development activities (such as the placement of roads).

The responsibilities o (the California Department of
Fish and Game and the U.S. Fish and Wildlife Service are to
protect habitat, wildlife and sensitive species. They are
not concerned with other impacts that the development may
have, unless they would affect wildlife and sensitive
species This is somewhat different than the
responsibilities of the City of Poway, the lead agency,
which must implement C70A and balance many environmental,
economic and political factors. The first aim of the CDFG
and USF'-?S will be to reduce impacts to biological resources
to the extent possible under the two Endangered Species
Acts, the 1603 Agreement and the Clean Water Act. Tiey will
try to achieve no net loss of habitat value, and no impact
to endangered species. No net loss of habitat value can
also occur through compensation or replacement of habitat
values, such as by revegetaton after disturbance for a
road. The agencies regularly accept native plant
revegetation as a component of mitigation. Some habitats
are easier to replace than others, however replacement of
mature, 250 year -old oaks and huge sycamores is arguably
impossible. 'Management is also sometimes accepted as a
component of mitigation, such as Cowbird trapping to enhance
Least bell's Vireos populati�lns.
The Corps of Engineers, when seeking mitigation for
wetland impacts under Section 404, may require habitat
replacement at 5 acres for every 1 acre of willoc ✓- dominated
habitat affected. The Corps may require higher levels for
the loss of mature oak and sycamore trees, since they are
slower- growing than willows, and their habitat value
equivalency would be achieved through revegetation much
later. An alternative is off -site mitigation. This concept
relies on protecting a habitat of equal or greater value
than the one being impacted. Essential to this type of
mitigation is the demonstration that the compensation area
is indeed threatened and could not be protected under
existing laws and policies. Potential impacts to endangere�
species and wetlands are beslt avoided altogether, or to the
absolute greatest extent possible.

Report on birds identified in the "North Stoneridge" project area
Philip Unitt
3411 Felton Street
Sari Diego, California 92104
I visited the "North Stoneridge" project area on 26 January
and 1 February 1986, spending from 7:00 A.M. to 1:00 P.M. on the
former date and 7 00 A.M. to noon on the latter. On 26 Jan I
searched the soutnern and western sections of the property, and
on 1 Feb the northeastern. Some southern, central, and northwest-
' ern sections I visited on both dates. Although I could not census
for birds exhaustively in the time allotted for this survey, by
common plants are Eriogonum fasciculatum, Artemisia californica,
and Rnus laurina. Most birds seen there were characteristic of
this haoitat. Although there are several dozen oak trees on the
site, they are apparently too small and few to support birds
cnaracteristic of the oak woodland community. Plain Titmice,

walking through the property in such a way that I was at some
time within 0.1 mile of any point within it, I believe I saw an

The most important area on the property for birds was the allu-
vial fan encompassing the northwestern and western perimeter.
Within this, the low ridge leading toward the small isolated hill
just outside the property was home to the largest number (three
pairs) of gnatcatcaers.

Tne only true woodland birds seen on the site were two Nuttall's
Woodpeckers on 1 February. The scrub in some parts of the prop-
erty is dense enough that a few birds more characteristic of
chaparral, (Canon Wren, Hermit Thrush, and Fox Sparrow) were
present in small numbers. The avifaunal composition of coastal
sage scrub and chaparral in San Diego County is very similar,

southwestern California. It occurs,. although no more commonly,
in other habitats as well, and is not known to differ taxonomi-
cally tnroughout its range. The two roadrunners heard calling on
1 February were on the same low ridge in the northwestern section
of the property discussed below under California (Black - tailed)
Gnatcatcher.
On 26 January I saw two Sage Sparrows (Aimophila belli
belli) together in the central southern section of the property
(see green dot on map) . On 1 February I saw a single Sage
Sparrow singing at the same spot. I interpret this as indicating
the presence of one territorial pair. Sage Sparrows are not
restrictea to coastal sage scrub (they are actually more common
in chaparral) but they merit attention because of a another
aspect of their habitat preference - -a predilection for mesa tops
and other areas of nearly flat topography. The pair on the
"North Stor;eridge" site was in a gently sloping area. The pauci-
ty of Sage Sparrows on this site probably reflects its generally
1 rugged relief, among other, unidentified, factors. Historical
data indicate that Sage Sparrows were once common in the San
Diego metropolitan area, where they are now nearly or quite
extirpated. In addition,. 11 years of data from Christmas Bird
Counts indicate that this species does not occur regularly in the
vicinity of Oceanside, Vista, or Carlsbad. The Sage Spar-
row's status in central western San Diego County is not well
;mown. I have identified only two areas in the county where A.
o. belli is common: Barona Mesa 6 miles southeast of Ramona and
A cCain Valley northeast of Boulevard (A. b. nevadensis and.possi-

bly A. b. cane,scens occur commonly and winter visitors in the
Borrego Valley). Because A. b. belli prefers a habitat and
topography easily developed for human use and is already absent
from large sections of the coastal zone, I infer that it is in
danger of being eliminated completely from western Sari Diego
County.
I found Rufous- crowned Sparrows (Aimophila ruficeps lambi)
in a aensity high for that species on 1 February in two areas in
the northwestern section of the "North Stoneridge" property,
indicated on the map by red shading. The physical environmental
features preferred by Rufous - crowned Sparrows, rugged and rocky
terrain, are essentially the opposite of those sought by Sage
Sparrows. A mixture of boulders, sage scrub, and grass is ideal
habitat for Rufous - crowned Sparrow. Therefore the occurrence of a
substantial population of this species on the site should have
been expected. Because Rufous- crowned Sparrows prefer a habitat
that is more difficult to develop and because they often colonize
the early successional stages of sage scrub following a fire,
their population in western San Diego County is probaoly larger
than that of Sage Sparrows. However, the species is restricted
almost entirely to the region west of the 1500 -foot contour; only
a few scattered pairs occur above this elevation. Also, Rufous-
crowned Sparrows were absent from the northeastern section of the
"North Stoneridge" property, where the vegetation was in an early
successional stage following a fire, indicating a limit to the
species' ecological flexibility. The vegetation in the north-
eastern section of the property consisted of low grass and -other
nerbaceous ground - covering plants with scattered laurel sumacs

and almost no low, dense shrubs such as Artemisia californica or
Eriogonum fasciculatum. I believe the absence of such low, dense
vegetation accounts for the current absence of Rufous- crowned
Sparrows from this northeastern. section. Because this subspecies
of Rufous - crowned Sparrow is nearly restricted to the. region of
southern California subject to the greatest demand for human
cevelopment and comparison of current with historical data indi-
cate that a sunstantial reduction of its population has occurred
already, I suggest that areas such as the northwestern section of
the "North Stoneridge" property supporting appreciable numbers of
Rufous - crowned Sparrows be retained with their natural vegetative
cover.
Tne most critical sage scrub species I identified during my
two visits was the California (Black - tailed) Gnatcatcher, Polio -
ptila (melanura) californica. The six pairs found were at the
places indicated with black dots on the map. Three of these were
near the northwestern perimeter of the property on a low ridge
leaaing toward a small isolated hill just outside the property
boundary. I found two of these three pairs on 2.6 January. On 1
February, after I had found the third pair, I returned to the
area where I had found the first two pairs and relocated them in
the same places. Two of the other pairs were along the alluvial
fan forming the western and northwestern margins of the property.
The sixth pair, seen only on 1 February, was near the center of
the property just northeast of the grove of eucalyptus trees.
Four of the six pairs were in dense low scrub consisting of a
mixture of about equal nuumbers of Artemisia californica and

Eriogonum fasciculatum, one pair (near the northern boundary) was
in essentially pure Eriogonum, the sixth (central) was in essen-
tially pure Artemisia. All were on gently sloping or nearly flat
ground. California (Black- tailed) Gnatcatchers merit special
attention since they occur north of the Mexican border only in
southwestern California, occur in this area only in coastal sage
scrub dominated by Artemisia californica, favor level or gently
sloping terrain, may suffer from brood parasitism by Brown- headed
Cowoiras, and have evidently already suffered a substantial popu-
lation. reduction. I recommend that the alluvial fan encompassing
the entire western and northwestern perimeters of the property be
left as natural coastal sage scrub habitat. If this is not
possiole, then at least the low ridge where three of the six
pairs occurred snould be reserved.
I conclude that the alluvial fan on the northwestern and
western edges of the "North Stoneridge" property is the most
critical bird habitat [five pairs of California (Black - tailed)
Gnatcatchers, two Greater Roaarunners, most Rufous - crowned Spar-
rows], the gently sloping areas in the center of the property are
of intermediate significance (one pair of gnatcatchers, one pair
of Sage Sparrows, some Rufous - crowned Sparrows), and the steep
hills in the southwestern and northeastern corners ate of least
importance. The dearth of birds on the northeastern hill is due.
prooanly to to the fact that the hill was burned rather recently
anu the vegetation on it is still sparse.
Proper habitat manacement for preserving coastal sage scrub
oirds cannot be scientifically based because some fundamental
questions remain, to my knowledge, unanswered. These questions
n.
I
include
1. What extent of habitat is necessary for each species to main-
tain a self - sustaining, genetically viable population?
2. Should a sage scrub habitat reserve be burned in its entirety
(an inevitable event), how close must the next nearest population
oe to ensure that birds will oe able to disperse across unfavora-
ble habitat and recolonize the reserve after vegetation regenera-
tion?
3. How much disturbance from human civilization (off -road vehi-
cles, chilaren playing, dogs being walked, feral cats), an
inevitable accompaniment of nearby development, is each species
aol.e to tolerate?
4. To what extent will erosion from construction activities
disrupt nearby habitat left in its natural state?

1.0 Abstract
The archaeological reconnaissance of the 1,300 —acre
Stoneridge East property resulted in both the discovery of new
sites and the relocation of previously recorded sites. In all,
27 resource locations are now known to exist on the project,
including ten milling sites, four surface scatters of artifacts,
four isolates, four artifact scatters with possible midden
deposits, two historic sites, two previously recorded sites which
had been mismapped and which were not relocated (the recorded
locations of these sites have been noted on the Resource Location
Map on page 8), and one previously recorded site that w -as
destroyed during the improvement of Old Coach Road. In general,
the resources on the property comprise a moderately significant
group of sites that represent parts of a food collecting and
processing pattern, principally associated with the late
prehistoric Indians. From the standpoint of the constraints
analysis, six of the sites have the potential (albeit small) to
be significant and would likely be impacted by any development.
The evaluation of these six sites for significance would require
further testing and analysis. The remaining 19 site locations
are not projected to be potentially significant, and would not be
likely to represent a.concern for future development.
2.0 Introduction
2.1 Existing Setting
The Stoneridge East property contains a variety of
topographic characteristics, from steep slopes and narrow

n
ridgelines to flat valley floors. The topographic setting would
have been a contributing factor to the pattern of occupation by
prehistoric people. In general,, inaccessible or rugged terrain
was ignored or bypassed by prehistoric Indian groups in favor of
water and food sources along the valley floor. Steep and rugged
terrain accounts for approximately 900 acres, or three- fourths of
the project. The remaining acreage is either flat or moderately
sloping, and this one - fourth of the project contains nearly all
of the resources recorded within the property.
The biological setting at the property corresponds to the
topography. The lush and varied plant species are generally
located in the one - fourth of the project which consists of richer
soil and higher water concentrations in the valley bottom and
adjacent moderate slopes. This area also includes the locations
of the recorded archaeological sites. The three- fourths of the
project comprised of steep, rugged terrain is typified by a
sparse chaparral environment, except in the narrow drainages,
where the chaparral becomes very dense. The sparse chaparral
environment contained only one milling site, reflecting the
minimal importance of this biological resource area.
2.2 Archaeological Site Files Record Searches
Archaeological site files record searches were obtained from
the Cultural Resource Management Center at San Diego State
University and the San Diego Museum of Man. These records have
been included in the appendix to this report. A total of six
sites had been previously recorded within the Stoneridge East
property. These sites include W -1295, W -2024, SDi -807, SDi -808,

W -1738 and SDi -4569. During the course of the survey, each of
these sites was the subject of a relocation effort; however, W-
2024, recorded by Malcolm Rogers in 1924, could not be relocated,
and SDi -4569, noted by G. Fink in 1973 as an adobe, was also not
relocated where it had been recorded. In all likelihood, SDi-
4569 was mismapped and should actually be located where the adobe
ruins were recorded during the present survey.
1
3.0 Field Reconnaissance
The project was surveyed in its entirety. The level of
effort varied and was dependent on the terrain and vegetation.
In the areas of steep and rugged terrain, the survey was
completed intuitively, focusing on specific locations such as
bedrock outcrops or strategic terraces. The greatest
concentration of effort was expended on the moderate slopes and
valley bottom, where expectations were greatest for the discovery
of cultural resources.
3.1 Results of Field Reconnaissance
The record search information (provided in the appendix)
denoted the presence of six sites on the property. As stated
previously, Sites W -2024 and SDi -4569 were not relocated. The
description of SDi -4569 matches that of Site SR -3 discovered
during the survey and identified as the Green Valley Stagecoach
Station. However, Site SR -3 will be re- recorded with a new
number from the Museum of Man and San Diego State University,
rather than attributing the site designation, SDi -4569, to it.
The sites discovered during the survey are listed on page 7

and plotted on the map on page 8. Temporary site designations
(SR - for Stoneridge) have been used for sites identified during
the reconnaissance which lack formal site numbers. The most
numerous type of resource consisted of eleven milling sites.
These areas denote the processing of seeds, usually acorns, for
food and are generally located adjacent to waterways and oak
trees (riparian habitats) . The next most numerous type of site
consisted of seven artifact scatter /midden locations. These
sites often represent areas of temporary occupation during
periods when food collecting and processing activities were being
conducted. The final group of prehistoric sites includes four
isolated artifact 1-ocations. In addition to the 23 prehistoric
sites noted, two historic sites are .present within the property.
The final three sites include SDi -808, which has been destroyed,
and Sites W -2024 and SDi -4569, which could not be relocated.
The collection of prehistoric sites included within the
project, on the whole, represent a relatively minor resource
group when compared to the size and significance of
archaeological sites in the near vicinity. In Table 1, each of
the sites has been assigned an initial evaluation of potential
significance -- low, medium, or high. These ratings are based
solely upon data gathered during the survey and lack sufficient
detailed information for verification. They are, however,
reasonably accurate for the purposes of the constraints study.
The evaluation of potential listed in the table on page 7
illustrates that Site SR -3, SR -6, and SDi -807 are considered
4
potentially important. This reflects that fact that the three
sites had characteristics which implied significant data
potential. If this were to be verified by testing, then these
sites would require mitigation plans prior to development.
Four sites are included in the category which reflects a
medium potential for significance. These include SR -4, SR -7, SR-
9 and SR -14. The level of potential for these sites would be
rdetermined by a testing program; however, the characteristics
observed indicated that these sites would not be likely to
represent significant resources.
The lowest rating of projected potential has been given to
Sites SDi -805 SDi -4569 W -2024, W -1295, 11-1738, SR -1, SR -2, SR-
5, SR -8, SR -10, SR -11, SR -12, SR -13, SR -15, SR -16, SR -17, SR -18,
SR -19, SR -20 and SR -21. Each of these sites lacks the
characteristics of significance and would not be expected to be a
potential constraint on the project.
In summary, seven sites have been preliminarily evaluated as
having a high to medium level of potential for significance. The
definitive evaluation will require detailed surface analysis and
subsurface testing, and would be part of an environmental impact
report., as this type of substantial evaluation is required by
law. The testing could be completed during the early planning
stages also, in order to provide development planners with
rinsights concerning. the potential of any of these sites to affect
the project layout.
Of the resources present at the Stoneridg.e East project,
Site SR -3 has the greatest potential to be a sensitive location.
1
J
1 This site consists of the remains of the Green Valley Stagecoach
Station, a part of the Butterfield Stagecoach Company circuit.
such historic sites often represent objects of deep public
interest because of their association with the development of the
"backcountry" in this area. Although the significance of the
site has not been evaluated through a historic archaeological
approach, public interest in its investigation should be
anticipated.
5.0 Conclusion
From the standpoint of this constraints analysis, the
cultural resources at the Stoneridge East project do not appear
to be a serious threat to the progress of the development. The
resources will require additional testing to verify the
preliminary evaluations, and may require mitigation measures in
some cases prior to final map approval. None of these programs
should be a major constraint to the development. The majority of
potentially important sites are situated in the center of the
project, near the course of the creek which drains through Green
Valley. It is much less likely that the remainder of the
project, especially the northern 600 acres, contains any
sensitive sites.

CULTURES:_ SD -II and III and
Lit . II ?, Y -III (We Diegueno )
WATEIR CONDITIONS: Long narrow
ceinaga with water holes.
LOCATION: Greater part of Greer.
Valley. Elev. 5001.
NAME: Green Valley.
AREA: Practically all the rolling
hills of the valley involved.
Equals la miles x 2 miles.
ARCHITECTURE: Some Lit. II TYPE: Open camps on rolling hills
or Y -III cobble hearths. At and one in big group of
W-208 -A area few boulders, wind granite boulder shelters.
break walls between the shelters. Some sites permanent.
B::RIALS: At W -208 -B a relic hunter claims to have dug up a cinerary
urn in a flat between the boulders. The big Y -III camps have been
plowed down to hardpan level so long that any cremation had they
existed would long ago have been scattered beyond recognition.
PETROS: This valley contains the greatest number of pictographs I
have seen. They are on white granite outcrops of great boulders on
the hill tops. There are four main groups. At W -208 -B there are 2
boulders with petroglyphs on them which run principally to punctates.
INTRUSIVES:
HISTDRY: SD -II people first came into this valley and camped on every
rolling hill in the region without creating concentrations to any extent.
W -208 -A was the richest site. The area was abandoned apparently in
early SD -III times as very little of this pattern is present. After
them there is a doubtful Lit. II occupation as no stratigraphy exists
and the idea is based on a few sherdless area. During Y -III times a
very strong occupation by W. Dieguenos occured, specially at the (B)
and (H) sub - areas.
REMARILS: Bedrock mortars and metates occur but not in the nub-n6rs
one would expect for the degree of occupation. This site marks, the
most southeasterly occurance of the so- called bowling stones, also the
most southwesterly occurrence of more pictographs. It shows strong
Luiseno acculturation archaeologically.

boulder perched on the east side of
the creek valley upon wriic_•! are 2
groups of pictographs. On the east undercut side is a living shelter
with a group of crude black pictographs (manganese) most of them being
merel; parallel streaks. On the west side in a pocriet in the bo:zlder
31 in diameter is another group in red and one reddish brown picto.
This is typical Diegueno work in that they and especially the E. Dieguenos
placed their pictos in their living abodes such as rock shelters.and
caves. Some worked stone and sherds were in this shelt.er..
IN-, ., S I ti'..S:
HISTORY: The main camp and the pictograph site were pure Diegueno
sites and no earlier cultural material wa -s found in the can -yon.
Scattered occupati -on exists all the way downy the canyon to its junc-
tion with the San Pasqual or San Dieguito River.
Rr S: Very little archaeology exists on the camp site and it
is considerable eroded. Bedrock metates and - ortars present.

SITE DESCRIPTION Surface indications suggest the site may represent a
resource procurement or resource manipulation area. The site is located
on the southern slope of the property overlooking the intermittent stream
Surface artifact inventory includes quartzite and granite manos, one hammer -
stone and various slightly patinated flakes of quartzite and basalt One
bedrock mortar exists on the western part of the site.
CULTURAL ASSOCIATIONS. Pottery was lacking, suggesting a preceramic
occupation.- The presence of patina on the flakes suggests some degree
of antiquity for the site. However, lack of pottery may also suggest that
specialized activities occurred here that didn't require the use of ceramics
Other suggestions are also possible, however, site testing and analysis
of the material would be necessary to make positive cultural associations
PREVIOUS.SITE DISTURBANCE The site area has been plowed over in the past.
Several small erosional arroyos have. been formed on the side - slopes. Also,
a large ditch has been cut along the contour of the hillside to prevent water
from running down onto the golf course.
SITE DEPTH Only one indication of site depth was noted. One basaltic
flake was exposed in a bulldozer cut at a depth of 20 cm , located at the
easternmost boundary of the site
SAMPLING STRATEGY. No collections were taken No diagnostic material
was noted.

PROPERTY AND LOCATION ANALYSIS
In this section is a description of the subject site and, an
analysis of essential physical characteristics.
SITE DESCRIPTION
The subject site is a 1,285 -acre irregularly shaped parcel of
undeveloped land within the incorporated City of Poway, California. It is
bounded by Espola Road to the south and the StoneRidge Country Club to the
west.
REGIONAL LOCATION AND ACCESS
Poway is located in northern San Diego County approximately 20
miles north of downtown San Diego and more than 100 miles south of Los
Angeles. Interstate 15 is the main north /south arterial connecting Poway
with Escondido to the north and leading to San Diego to the south. See
Exhibits III -1 and III -2.
CIRCULATION
Circulation in Poway is primarily provided by four major roads
Espola, Pomerado, Poway and Twin Peaks.
Espola Road, the southern property boundary, is the main route
serving the northern residential areas and its extension, known as Rancho
Bernardo Road, provides access to I -15. It runs east /west in the
StoneRidge area and north /south in the Twin Peaks Road area. Espola Road
is designated as a local scenic roadway.

U!"
Pomerado Road is a main north /south route for Poway. It turns
westward and connects with I -15 at its northern and southern ends. It
connects Rancho Bernardo to the north and Scripps- Miramar Ranch to the
south.
Poway Road is the main east /west road in Poway and is the City's
primary commercial corridor. It has full on /off access to I -15.
iTwin Peaks Road is an east /west access route connecting with I -15
and is designed to alleviate congestion on Poway Road.
Old Coach Road; now paved for a short distance, is an access route
within the subject property. One proposal is to extend Old Coach Road
northwest and connect it with Highland Valley Road. This or a similar
alternative is intended to serve as the main internal route. The subject
development is intended to have one major access road.
SURROUNDING AND PROXIMATE LAND USES
The southwest portion of the property borders on StoneRidge, a
residential community with a country club focus. A residential develop-
ment is immediately to the south and a smaller one is located to the
east. Vacant land borders the remainder of the property. StoneRidge
Country Club is controlled by one of the joint venture partners and there
is an opportunity to tie -in with the existing golf course. The area on
the north boundary is used for agriculture.
1 TOPOGRAPHY
The property has interesting and varied topography offering oppor-
tunities for expansive views. Areas with steep-slopes unsuitable for
development can be left as open space.

IV -1
This section presents a general description and overview of popula-
tion trends and economic factors in the San Diego metropolitan area.

States, encompasses 4,280 square miles. Virtually all of the population
inhabits the western third of the county.
The City of San Diego is the second largest city in California and
the county seat, and offers educational facilities, major tourist.attrac-
firms
tions and a convention center. The region headquarters electronic
and is a mecca for oceanographic research and development.
DEMOGRAPHIC OVERVIEW

The City of Poway is projected to grow commensurate with the County
at a 2.03 percent compound annual growth rate over the next 15 years.
While population is expected to grow 46.6 percent, housing units are to
grow even faster, 60.6 percent, resulting in a declining household size
from 3.21 to 2.93. (See Exhibit IV -1.)
Nonagricultural employment for the San Diego SMSA is 791,600,
representing 7.2 percent of California's total. There are some distinct
differences in the employment distribution of San Diego vis -a -vis that of
the state. For example, 15.1 percent of the San Diego labor force is in
manufacturing versus 18.6 percent for the state. San Diego is heavily
weighted in government: 18.9 percent versus 16.1 percent. (See Exhibit

California.
HOUSING STARTS
As measured by housing starts, San Diego is the third fastest
growing area in the nation: housing starts are expected to grow 63 per-
' cent in the 1985 -1989 period, compared with the preceding five years. The

CITY GOVERNMENT
Poway has the council - manager type of city government.
REGIONAL FACTORS IMPINGING ON SUPPLY
On November 5, 1985, the citizens of San Diego voted on and passed
Proposition A, an amendment to the Progress Guide and General Plan.
Section 1 of Proposition reads as follows.
"No property shall be changed from 'future urbanizing' land
use designation in the Progress Guide and General Plan to
any other land use designation and the provisions restrict-
ing development in the future urbanizing area shall not be
amended except by majority vote of the people voting on the
change or amendment at a Citywide election thereon."
The purpose of the initiative is to preclude premature development
and to guide urbanization. San Diego City planners feel that-the initia-
tive will not have an immediate effect because there is now sufficient
land available in the City for urbanization. The effect might be felt in
unincorporated areas which may have wanted to annex to the City in order
to gain utilities and services. The long -range effect may be to increase
demand for housing in other cities in the county.

November 1985, and Economics Research Associates.
The proposed supply of 149,000 units will take almost ten years to
absorb at the 1985 rate of 15,500 units .per year. The proposed supply
does not necessarily imply an excess of planned product for the following
reasons:
1. Sales of new units over the next few years could be consider-
ably higher than experienced during the depressed levels {of the
past few years -- early indications for 1986 are very
encouraging.
V -3
P'
a
2. Some of these units are new projects and additional phases of
existing projects and many will never be built.
3. Because of the very long and extended periods required to gain
subdivision approval, developers must start the planning pro -
cess way in advance of anticipated construction.
4. Countywide.statistics do not necessarily reflect the conditions
in local markets and cities — some markets and.submarkets
could be undersupplied in the years to come.
5. The free - market mechanism works best when the consumer has a
great number of choices.
RESIDENTIAL PRODUCTS CONSIDERED
The following products were considered for development on the
subject property.
Custom homesites 2 acres or more in size. These sites can be
located on hillside lots offering panoramic views.
Golf- oriented lots are smaller than custom sites and offer golf
ifrontage and views. These are 6,000 square feet or more.
Detached tract lots one - quarter to 1 acre in size.
Zero lot line lots varying in size from 3,500 to 5,000 square
feet.
Attached lots varying in size from 3,500 to 5,000 square feet.
Condominium -- air space subdivision for stacked flat development.
High- density rental -- apartment house development.
tLow- income housing consisting of high- density, low -cost
® construction.

Conventional senior housing -- lots appropriate for,smalier homes.
Senior individuals, i.e., those over 55 years old live in any type
of home but tend to move into smaller homes requiring less
maintenance.
Institutional senior housing -- retirement homes and continuing —
care facilities.
r PRODUCT SUITABILITY RANKINGS
i U
Each
of the nine products were rated for suitability with respect
to 16 factors. The first four factors are considered primary and the
remaining 12 secondary. (See Exhibit V -1.)
1.
Local government attitudes and expectations favor low- density
housing conserving the rural character'of the.area as
stipulated in the General Plan.
2.
Absorption potential is relative to the product and greatest
for low - density housing and senior housing, and unsuitable for
low- income housing.
3.
Topography is varied and steep in some areas affording
hillside sites which are suitable for low- density products.
Development for low - income housing would be cost - ineffective.
The more level areas are more suitable for higher density
products.
4.
Low density, - be
- golf oriented products would compatible with
surrounding land uses.
5.
Community attitudes are somewhat reflected in the General Plan
and favor low- density, rural development.
6.
Employment opportunities are generally located within
commuting distances to areas with office concentrations and
1
industrial concentrations. People living in low- income
housing and rental housing prefer to live closer to employment
centers.

RESIDENTIAL PROJECT CHARACTERISTICS
There are numerous residential projects within. the market area.
The closest is Bridlewood by R.B. McComic on the south side of Espola
Road. This is a successful project featuring homes on 20,000- square -foot
sites and custom lots from 27,000 square feet to more than 3 acres.
Prices for homes have increased about 6 percent since inception on October
1985 and now range from $155,000 to $215,000.
Woodside Arbolitos by Standard Pacific, also in Poway., is a 760 -
acre project with a total of 900 units planned in various phases. Lots
are 10,000 square feet, homes range in size from 1,588 -3,073 square feet
and prices range from $144,000 to $239,000.
Other selected projects are listed in Exhibit V -2. Generally,
there is broad acceptance of upscale large -lot housing in the market
area.

how the subject property may offer an opportunity for this type of
development.
SENIOR HOUSING STAGES AND REQUIREMENTS
As individuals age, their housing needs change as described by the

following four
stages.
Stage 1
— Children leave home and parents, as empty nesters, need
smaller homes. These individuals are active and have
more time and disposable income for recreation and
travel. Zero lot line and attached homes are
particularly suitable at this stage.
Stage 2
-- Now retired, they have much more time for recreation and
travel. Zero lot line, attached and condominiums are
suitable at this stage.
Stage 3
-- A slight decline in health or concern that it may, a
spouse's death, a desire to reside with peers and have
basic cooking /cleaning services provided are all reasons
motivating an individual to elect a retirement home for
the ambulatory.

Conventional senior housing demand can be satisfied with higher
density product types in either an open or age- restricted environment.
Conventional senior community housing is generally age- restricted and
offers an active recreational environment. To comply with State law for
age restriction, the communities have gated entrances, and the streets and

Section VII
NEIGHBORHOOD SHOPPING CENTER ANALYSIS
This section contains a discussion of the suitability for develop-
ing a neighborhood shopping center on the site.
NEIGHBORHOOD SHOPPING CENTER OVERVIEW
F
I VII -1
Neighborhood centers cater to the daily needs of the surrounding
neighborhood. The primary tenant is usually a supermarket and other
tenants may include a drugstore, variety store, dry cleaners, beauty
parlor, post office, employment office, and real estate office.
The neighborhood center is 2 to 10 acres in size and, designed to
serve from 5,000 to 40,000 people living within 1 to 2 miles from the
center. The primary market area for the center is dependent on population
density, visibility, access, and competing centers.
COMPETITIVE CENTERS IN POWAY
There are six neighborhood centers that currently serve the Poway
area. (See Exhibit VII-1.)
Bernardo Road, 2.5
1. Safeway Center -- Pomerado Road and Rancho
miles west of the site.
3/4
2. Rancho Bernardo Center — South side Rancho Bernardo Road,
mile west of Pomerado Road.
3. Ralphs -- Road.
NWC Pomerado Road and Bernardo Heights
4. Vons — NWC Poway Road and Pomerado Road.
5. Food Basket — NWC Poway Road and Silver Lake Drive.
6. Safeway Super Store -- NEC Poway Road and community.

SUITABILITY FOR NEIGHBORHOOD CENTER
We have evaluated three alternative sites for developing a neigh-
' borhood center (Exhibit VII -1).
A. Corner of Espola Road and Old Coach Road.
B. One hundred yards north of Espola Road on Old Coach Road with a
natural buffer between the center and Espola Road.
C. One -half or more miles north of Espola Road on extended Old
Coach Road.
1 The following is a brief evaluation of these sites.

Proximity to Residential Base 3 3 3
Average 3 2.5 2.3
Note: 5 most suitable; 1 = least suitable.
Source: Economics Research Associates.
Site A, offering visibility and access, is the site most suitable
for locating a neighborhood center. Site B may be more acceptable by the
community and by the City of Poway but is somewhat hampered by lack of
visibility and access from Espola Road. Site C, located farther from
Espola, may be most acceptable to the community and City but would be at a
great disadvantage in attracting the necessary market support. A center
in a good location would have a higher probability of success, provide
tconvenient shopping to the neighborhood and increase the tax base of the

City. A center in an inferior location would have difficulty in
attracting a high - quality supermarket anchor tenant.
A neighborhood center strategically located on the site is worthy
of consideration and would greatly benefit residents who now have to drive
almost 2 miles to the nearest supermarket.

Section VIII
ANALYSIS FOR RESORT HOTEL
This section contains a brief analysis of the suitability for
developing a resort hotel on the site.
RESORT HOTEL OVERVIEW
Resort hotels in San Diego County benefit primarily from three
attributes: exceptional climate, natural aesthetics and ocean access.
Inland resorts feature golf and tennis and some equestrian facilities.
(See Exhibit VIII -1.)
The closest resort hotel to the subject site is the Rancho Bernardo
Inn. This 236 -room complex offers golf, tennis and swimming pool in a
beautifully landscaped setting. The in- season rack rate for double occu-
pancy ranges from $130 to $150 per night. Rancho Bernardo has a signifi-
cant concentration of office and industrial occupants which is a good
business base for local lodging. Existing downtown motels are not resort -
oriented and would not compete directly with the proposed high -end lodging
facility.
RESORT LODGING SUITABILITY
The suitability for a resort hotel featuring golf, tennis, swimming
pools and health club is evaluated as follows

Section IX
OFFICE AND INDUSTRIAL ANALYSIS
This section contains an analysis of the potential for developing
office and industrial land uses on the subject property.
OFFICE MARKET OVERVIEW
Office users have provided a powerful driving force to San Diego's
economy. The demand for office space reflects exceptional employment
growth in professional services. During 1985, over 2 million square feet
were absorbed, with approximately one -fifth taking place downtown.
The highest concentration of space is downtown with 6.8 million
square feet comprising 29 percent of the region total. The I -15 corridor
is closest to the subject site and represents 11 percent of the region
(see Exhibit IX -1).
INDUSTRIAL MARKET OVERVIEW
San Diego's economy, once dependent on military and aerospace, has
now a broad economic base with emphasis on high - technology and services.
San Diego has renowned research and manufacturing capabilities in bio-
medics, electronics, aerospace, computers and oceanographics. The
University of California at San Diego, the Salk Institute for Biological
Studies, and the Scripps Clinic and Research Foundation are world class
research and educational institutions.
The San Diego industrial market consisting of warehouse and dis-
tribution, manufacturing, and RED is essentially concentrated in 12 sub -
markets and contains a total of 31.2 million square feet. The five
largest concentrations are Miramar with 5.5 million square feet, Kearny

Mesa with 5.2 million square feet, South Bay with 3.3 million square feet,
Sorrento Valley with 3.2 million square feet and the I -15 corridor with
2.9 million square feet. (See Exhibit IX -2.)
The I -15 corridor is closest to Poway and bounded by Rancho
Bernardo on the north and Scripps Ranch to the south. Development began
in this area as available land in Kearny Mesa became scarce. Most of the
space is occupied by major high - technology users including NCR, Hewlett -
Packard, Sony, Burroughs and TRW.
