A. THE ENVIRONMENTAL IMPACT OF THE PROPOSED ACTION
The proposed project, El Camino Glens, is a subdivision of
311 acres of land. With the exception of a small ranch complex,
the project site is primarily undeveloped land. It is located at
the intersection of El Camino Real and Olivenhain Road, southwest
of the City of Carlsbad.
The developer, La Costa.Land Company, is presently applying
for approval of a pre-annexational zone change. Following
annexation to the City of Carlsbad, tentative maps and specific plans
will be submitted for approval, leading to development on the
project site.
The small parcel of land which is located northeast of the
intersection of Olivenhain. Road and El Camino Real, but is not
included within the project boundaries for El Camino Glens, will be
considered for annexation concurrent with the proposed project.
This property is owned by Rancho La Costa, a partnership (Don
Ayres). The environmental setting of this parcel will be similar to that of
El Camino Glens. The impacts of its annextion will also be similar.
1. Project Description
The development of El Camino Glens will involve grading of
lots, construction of streets, and installation of improvements for
the future construction of 1450 single-family and multiple-family
residential units. The propo-sed plan intends to create a balanced
1
" ^"'"ij^i;te^^^^«^^m^^m^^^M^
££ CAMfNP^GLENS
Pivu^?SvrP/ \ \ W ?Xv^
community with residential, recreational and commercial facilities,
reflecting the needs of the population it will house. This will be
accomplished through a planned variety of density patterns, open
spaces, traffic patterns, and a neighborhood commercial area.
By initiating protective conditions and deed restrictions, the
La Costa Land Company will insure that future construction within
the project will adhere to certain minimum standards. Such conditions
as prior approval of structure and landscape plans, and the style,
design, appearance and location of the structure, will insure a
quality development. Alterations to the structure or to the landscaping
also require approval. Conditions have also been established to
insure maintenance of the lots.
The residential areas of El Camino Glens will be developed at
an overall density of 4.75 dwelling units per gross acre. The types
of units, lot sizes, or street configurations are not known at this
time. The proposed development plan contemplates a community
comprised of a mixture of garden homes, townhouses, and
condominium apartments with related commercial and recreational
facilities. A six acre commercial site will be set aside for future
construction of a neighborhood shopping center.
Areas of open space and parkways with bicycle and walking
paths will be provided in each portion of the development. A 150 foot
easement for San Diego Gas and Electric lines parallels the site along
the western boundary of the project. This easement will remain in
its natural state although some additional landscaping improvements
will be made to create a pleasant entry to the development.
Access to the property is at present from El Camino Real, which
runs in a north/south direction along the western boundary, and from
Olivenhain Road, which runs in an east/west direction along the
southern boundary. Proposed for construction as part of this project
is an access road from Santa Fe Glens, which would link Rancho
Santa Fe Road and El Camino Real.
Development of El Camino Glens will require grading of the project.
Grading of the project will be kept to a minimum. Cut and fill slopes
will be planted with ground cover to stabilize the slopes and reduce
erosion.
Utility service will be provided to all lots. Gas and electric
service for the proposed project are located within El Camino Real
adjacent to the project boundary. Sewer service will require
construction of a main north to the sewage treatment and pumping
plant at the intersection of El Camino Real and La Costa Drive. Water
service for the project will be from an existing main at the northern
boundary of the project. All utilities, with the exception of the
existing power lines within the San Diego Gas and Electric easement,
will be placed underground.
2. Environmental Setting Without the Project
The proposed project, El Camino Glens, is located in the county
of San Diego southwest of the City of Carlsbad. The property is
situated north of Olivenhain Road between El Camino Real and
Rancho Santa Fe Road with portions of the property contiguous to
El Camino Real and Olivenhain Road.
a. Topography
The project site is a 311 acre, irregularly shaped parcel of land.
The topography is characterized by a flat cultivated valley which runs
the entire length of the property in an east/west direction. The balance
of the land slopes gently upward from the valley to the northern property
line and to the eastern half of the southern property line. The land to
the southwest is higher in elevation and is separated from the valley
by a gradual slope.
The project site slopes and drains westerly into Encinitas Creek.
Elevations vary from 250 feet on a slope in the southeast to 70 feet
in the valley bottom in the westernmost portion of the site.
b. Land Use
The property is undeveloped except for the Wiegand Ranch complex
which is located approximately 600 feet east of El Camino Real in
the central portion of the property. A few dwellings and agricultural
structures are also located on the southern portion of the property.
There are a number of dirt roads on the project site. Most of
these roads are access roads for the ranch complex and its various
agricultural outbuildings. These roads also provide access to the
San Diego Gas and Electric lines which traverse the site. The area
has not been extensively used by off-road vehicles and some areas
C
still remain in a natural state.
The project site is bounded on the south by Rancho Del Ponderosa,
a proposed 120 acre development of 420 single family residences, and
by Olivenhain Road, beyond which lies largely undeveloped land
(zoned LC) . Beyond this temporary zone lies Village Park, a large
residential and commercial development (zoned R-l-A, R-l-B, R-2,
R-3, and C). This project, estimated to be completed by 1976, will
encompass an area of 900 acres. The development plan calls for
3761 units to be constructed at a density of 6.0 dwelling units per
gross acre.
To the northeast, El Camino Glens is bounded by La Costa South,
which is a residential subdivision composed predominately of
single-family units (zoned R-l-7500). The land east and northwest
of the project site is currently undeveloped (zoned PC) but is planned
for development as part of the La Costa Development. These
undeveloped areas are known as Santa Fe Glens and Spanish Village,
respectively.
The site is bounded on the west by El Camino Real. Agricultural
land (zoned A-2-8) lies beyond El Camino Real to the west.
Co Biology
The major vegetation assemblage on this site is made up of
grasslands, chamise chaparral., and coastal sage scrub. Also located
on this site are scattered small stands of coast live oak, scrub oak,
willow, and eucalyptus.
The grasslands, which comprise the majority of the vegetation,
are located in the central and northern portions of the site. They are
characterized by weedy, herbaceous dicots and grasses. The
chamise chaparral, located in the southwest and northeast portions
of the site typically contains chamise and mission manzanita. The
coastal sage scrub is the predominant vegetation in the southwestern
and northwestern portions of the property. It is characterized by
California sage brush, California buckwheat, laurel sumac, black
sage, and lemonade berry.
Two endemic species, or species which are restricted to a
particular region, which occur on the site are the mission manzanita
and the California adolphis.
The grasslands and various brush communities support a variety
of wildlife species which include small mammals and rodents, larger
vertebrates including predators, reptiles, and a variety of birds.
-The small mammals and rodents observed,or normally expected
to occur on the project site,were ground squirrel, cottontail rabbit,
jackrabbit, pocket mouse, and other rodents such as wood and
kangaroo rats. The larger vertibrates observed, or for which direct
evidence was found, include coyote, grey fox, badgers, striped
skunk, and spotted skunk.
Bird species observed at this site include Anna's hummingbird,
brown towhee, California thrasher, hermit thrush/ red-tailed hawk,
and assorted sparrows.
No reptiles were observed during the biological investigation
of the site because of their restricted activity during the winter
months. Reptiles to be expected in this habitat would include
rattlesnakes, gopher, garter and king snakes as well as several
types of lizards, toads and frogs.
No endangered species of plant or animal life were observed on
the project site and none are known to be dependent upon the area,
d. Geology
The project site is underlain entirely by the Eocene Del Mar
formation. This formation consits primarily of silty clay stone and
clayey to silty sandstone, with local concentrations of pebble-size
material. The sandstones are usually light buff to tan and the
mudstones are a grayish-green. These soils are generally quite
friable; individual grains are held together by the relatively high
clay content of the rock. Locally, thin beds are strongly indurated
by a calcareous cement.
Expansive silty clay and sandy clay were also encountered at
relatively shallow depths along the lower valley areas.
There are no adverse geological conditions within the project
area which would preclude development of the project. No evidence
of major subsidence or mudflows was observed on the site and none
are anticipated to occur during development. The only potentially
active fault near the site is located 8 miles southwest under the
Pacific Ocean.
e. Archeology
The site records at the San Diego Museum of Man were examined
to see if any sites had ever been recorded on the project site. It was
determined that no sites were ever recorded.
An archeological investigation of the El Camino Glens revealed
the presence of four small archeological sites. The first site contained
a thin deposit of La Jollan shell material. It is located on the
southwestern corner of a major ridge, at about 140-150 feet in elevation,
along the western margin of the project site.
The second site is part of a cluster of three closely related San
Dieguito III occupations about 500 feet apart along the southern margin
of El Camino Glens. This site is located on a west-north west trending
nose at an elevation of 180 feet. It consists of a scatter of crude
flakes and scrapers.
These first two archeological sites were determined to be of only
minor importance. The loss of these sites would not be scientifically
significant.
The third site located on El Camino Glens lies just south of a
small check dam and ranges in elevation from 150 to 180 feet. In
addition to crude flakes and scrapers, a knife blade (which is unusual)
was found on this site. This site was determined to be of virtually
no scientific value.
The final San Dieguito III site on El Camino Glens is located
*
between the 180 and 200 feet-contours, about 500 feet south of the
previous site. A test pit excavated in this site showed that it did
w
not extend below the surface. Among the tools found here were an
unusually large concentration of discoidal scrapers. This site
has already been salvaged as part of the archgeological investigation
of Rancho Del Ponderosa.
f. History
A historical investigation of the project site did not reveal the
existence of any sites of historical significance.
3. Environmental Impacts
a. Land Use
'
The proposed project, El Camino Glens, will allow a maximum
of 1450 families to move into a modern residential development which
utilizes the best principles of land use and design. Past history at
La Costa indicates that multi-family lots contained within the development
will be developed to a lower density than the maximum permitted,
resulting in a lower development population.
b. Geology - Grading
The nature of the soils found on El Camino Glens indicate they
can support the proposed development. Grading on this site will
change the natural land form of the project site from undeveloped terrain
into a residential community. The visual impact of the raw earth
exposed by grading will remain only until housing units are constructed
and landscaping is complete. Cut and fill slopes will be planted with
ground cover to stabilize the slopes and reduce erosion.
No adverse effects should result from grading of the site in
accordance with accepted engineering practices.
10
c. Biology
Development of the project will require the complete removal
of all vegetation from the graded portion of the project site.
Accompanying this loss of vegetation will be the displacement of bird
and animal populations which currently occupy the site.
This wildlife will be displaced either to undeveloped areas on
the site, or undeveloped areas off the proposed site. The larger
predators will face a reduction in their hunting territories because of
loss of habitat from development of this site. Competition for food
sources will increase with the introduction of unfenced domestic
animals.
\
No endangered species of plants or animals will be affected
by the proposed project.
New species of plants will be introduced into the area through
landscaping of the project site.
d. Archeology
It has been determined that the proposed site offers no
archeological resource of any significant value, thus there will be no
archeological impact resulting from the development of the site.
e. History
It has been determined that no historical sites are located on this
proposed development site.
f. Drainage - Water Quality
The drainage of the project site will change from overland sheet
11
flow in natural channels to flow in street gutters and underground
storm drains. Design of the storm drain system for the project will
be in accordance with current standards of the City of Carlsbad.
Runoff from the project site will increase with development.
The total drainage area of Batiquitos Lagoon is 52.3 square miles.
The project site represents less than one percent of the drainage
area, thus the increased runoff will have an insignificant effect on the
lagoon system.
There will be a minimal decrease in water quality because of runoff
from the project site. This decrease in water quality is caused by
various impurities such as hydrocarbons, fertilizers, dissolved
minerals and chemicals which are associated with runoff from urban
developments. This decrease in water quality is typical of development
and cannot be eliminated. The water quality in the project area has
already been effected through the use of chemical fertilizers on
agricultural lands,
g. Traffic
Traffic in the La Costa area will increase as a result of the
proposed development. The circulation system has been designed to
accommodate this anticipated traffic increase. El Camino Real is
indicated on the Circulation Element as a prime arterial, with an ultimate
capacity of 30,000 to 40,000 vehicles per day. The Circulation
Element of the San Diego County Plan, 1990, calls for construction
12
of a road, El Camino del Norte (SA 680), from Interstate 5 east, just
to the south of Olivenhain Road, to Poway. It is designated as a
prime arterial with an ultimate capacity of 30,000 to 40,000 vehicles
per day.
The amount of traffic generated by El Camino Glens will be
dependent on the nature of the future residents. Residents will be of
several broad groups including retired, second-home owners, and the
single home owners. This diversity of homeowners makes accurate
traffic predictions difficult. Traffic studies may be conducted to
evaluate changing conditions as they arise,
h. Noise
The existing noise level in the El Camino Glens area is low
because of the moderate volume of traffic on El Camino Real and
Olivenhain Road. The San Diego Gas and Electric easement bounding
El Camino Real will act as a buffer zone to reduce the effect of the
noise from El Camino Real on the project site.
Aircraft noise will occur occasionally, but it is not considered
to be a significant factor. The development is outside normal landing
and departure patterns of existing or planned airports.
Noise from the contractor's equipment and other construction
noises cannot be eliminated. This noise will be temporary, lasting
only until the project is completed.
i. Air Quality
The increase in air pollution resulting from this project will be
13
minimal. The main source of air pollution created by the project
will be from motor vehicles. In comparison with the total vehicle
emissions in the Carlsbad area, auto emissions and the resulting
pollutants from this project will be insignificant because of the
small number of vehicles involved. The quality of emissions from
vehicles cannot be controlled by the developer, but are regulated
by State and Federal Standards „
Pollutants from the exhaust of the contractor's equipment will
be within existing emission standards and will be of a temporary
nature.
j. Utilities
. Gas and electric service to the development will be provided
by SDG&E. These facilities are located in El Camino Real adjacent
to the project site.
The Leucadia County Water District is in the process of having
additional facilities built at its treatment plant site at La Costa
Avenue and El Camino Real, and from there to connect to the Encinitas
Treatment Plant. Sewer service for the project will require
construction of a main north along El Camino Real to the treatment
plant site.
Water is to be supplied by the Olivenhain Municipal Water District.
Sufficient capacity is available to provide water to the proposed
project.
Water service for the project will be provided from an existing main
14
along the northern boundary of the property,
k. Community Services
El Camino Glens is located within the San Dieguito Union High
School District. The developer is working with the school district to
insure the provision of adequate facilities for students from the project.
El Camino Glens is also located within the Encinitas Union
Elementary School District. Elementary schools are being provided
within the framework of the Master Development Plan for La Costa.
Sites for future construction of eight elementary schools are included
within the Master Plan. Two junior high school sites will also be
provided.
The City of Carlsbad Police Department services all areas within the
corporate limits of the City of Carlsbad and at present one patrol car
is on duty 24 hours a day in the La Costa area.. This patrolman would also
patrol the proposed site.
The City of Carlsbad Fire Department has a substation in La Costa
which will serve the proposed project. The substation is 2.8 miles
to the north of the project site.

B. ANY ADVERSE ENVIRONMENTAL EFFECTS WHICH CANNOT BE AVOIDED
SHOULD THE PROPOSAL BE IMPLEMENTED
The unavoidable adverse environmental effects resulting from the
development of El Camino Glens are typical impacts resulting from
construction of a residential development. There are no unique adverse
environmental effects which would result from development of the project.
The adverse environmental effects of El Camino Glens are:
1. To decrease the amount of agricultural and undeveloped land
in the City of Carlsbad and County of San Diego by 311 acres.
2. A minimal decrease in water quality associated with urban
areas (hydrocarbons, fertilizers, chemicals, dissolved
minerals, etc.)
3. To increase traffic on El Camino Real, Olivenhain Road, and
other roads.
4. A minimal increase in air and noise pollution associated with
the increased traffic.
5. A temporary increase in noise associated with construction
of the project.
6. A minimal increase in the demand for public utilities.
7. To decrease the available wildlife habitat in the area and to
displace wildlife from the graded portions of the project site.
Beneficial environmental effects resulting from the development of
the proposed project will be:
1. To provide a maximum of 1450 homes for families in the City
of Carlsbad. These homes will be located in the La Costa
Planned Development,which includes provisions for
recreational, service, educational, and commercial facilities.
2. An increased tax base in the City of Carlsbad.
3. An improvement of access routes for fire and police protection
and an expansion of water service to the project site and the
surrounding area for fire protection.
16
4. The long-term stabilization of the terrain resulting in
reduced erosion of the project site.
5. A substantial increase in the number of trees on the
project site.
6. An overall increase in vegetation on the project site.
17
W
C. MITIGATING MEASURES PROPOSED TO MINIMIZE THE IMPACT
Various measures will be taken to minimize the environmental
effects of the proposed development. Grading of the project site
will be kept to a minimum. Lot pads will be graded to slope away from
the lips of fill slopes, or drainage facilities will be constructed to
avoid damage to the slopes by storm runoff. Cut and fill slopes will
be planted as early as possible to stabilize the slopes and reduce
erosion. This will also reduce the visual impact of the project until
the individual lots can be landscaped by their owners.
By initiating protective conditions and deed restrictions,the
La Costa Land Company will insure that future construction within the
project will adhere to certain minimum standards. Conditions such as
prior approval of structure or landscape plans,and the style, design,
appearance and location of the plans will insure a quality development,
Other conditions include the exclusion of external television
antennas, trailers,temporary buildings,boats and signs.
The natural vegetation of the SDG&E easement will be retained
and some additional improvements will be made creating a pleasant
entry to the development.
An investigation of the project site was conducted to determine
the existence of archeological or historical resources on the site.
No historical sites were discovered and only four minor archeological
sites were uncovered. Since they were judged to tie of minor
significance, no further mitigating measures are required.
18
c o%*•
All utilities, except the power lines in the San Diego Gas and
Electric easement, will be placed underground to eliminate their
visual impact.
Additional mitigating measures are the result of the total La Costa
Development Plan. Over thirteen percent of La Costa can be classified
as Open Space. Some of this area is devoted to specific recreational
usage (the golf course,country club, spa,and riding facilities),
while most is left undeveloped to be part of an area-wide hiking,
equestrian, and picnic resource for the residents of the area. La
Costa also has provided approximately 200 acres of land for commercial
usage, including 110 acres for a regional shopping center.
19
r. . D
D. ALTERNATIVES TO THE PROPOSED ACTION
Many alternatives are always available regarding land use
decisions. The determination of the density of dwelling units and
their relationship to transportation facilities, utilities,community
services, and other land uses involves an infinite number of variables.
One alternative which is always available is to leave the property
under private ownership in its undeveloped condition. The property
was originally purchased with the intent of developing the land.
Additional funds were expended in the areas of engineering, planning,
and payment of city fees and assessments. The developers, unable
to recover their investment from the property, would suffer financial loss.
None of the environmental impacts discussed in this report
would occur if the "no-project" alternative is selected. However,
other impacts would occur to the site through human and vehicular
activity on the site. This activity would result in displacement of
wildlife and disruption of the vegetation.
A second alternative is public acquisition of the site to either
retain it as an open space area or develop it as a park. No public
!
agency has expressed a desire to purchase the project site for
retention as open space or development as a park. There is nothing
unique about the project that would require its preservation.
Any other form of residential development would have impacts
similar to the proposed project. Development at a higher density
would place a greater demand on utilities and public services, and
20
more traffic would be generated. Development at a lower density
would require less utilities and public services, and less traffic
would be generated.
o
E. THE RELATIONSHIP BETWEEN LOCAL SHORT-TERM USES OF MAN'S
ENVIRONMENT AND THE MAINTENANCE AND ENHANCEMENT OF
LONG-TERM ENVIRONMENTAL PRODUCTIVITY
The basic long-term effect of the proposed project on the
environment is the loss of 311 acres of agricultural and undeveloped land,
The agricultural portion of this site, when developed, would preclude
any further use of this land for agricultural purposes. Accompanying
this irreversible loss would be the removal of a wildlife habitat.
There is nothing unique about the project site which would require its
preservation in its natural state.
The approval of the project is the commitment of the project site
to residential use. The project will permit a maximum of 1450 families
to move into a modern, adequate housing development. The predicted
growth of the entire San Diego County area requires further residential
development. Until growth of the population can be controlled,
either expansion or congestion must occur.
22
c
F. ANY IRREVERSIBLE ENVIRONMENTAL CHANGES WHICH WOULD BE
INVOLVED IN THE PROPOSED ACTION SHOULD IT BE IMPLEMENTED
The direct environmental effect of the proposed project is the
commitment of 311 acres of agricultural and undeveloped land to
urbanization. The property will be altered to accommodate
residential housing and in the process its physical and biological
characteristics will be changed.
The indirect effect of the project is the construction of housing
units and its resultant consumption of building materials and natural
resources. Public services and utilities will have greater demand
placed upon them.
23
c
G. THE GROWTH INDUCING IMPACTS OF THE PROPOSED ACTIVITY
UPON THE NEIGHBORHOOD AND/OR COMMUNITY
The growth inducing aspects of the proposed zone change,
and subsequent construction of the development, reflect an orderly
growth of residential use of land adjacent to already developed
La Costa residential property to the north. This growth will supplant
the existing agricultural use of the land. Further growth inducement
occurs on properties adjoining the subject property in the same manner
as the successful La Costa Development has already induced the
development of this property. Development of properties now occuring
to the south,notably the Village Park project in the Encinitas area,
also has growth inducing effects on the surrounding property.
Denial of this project would not appreciably diminish the present
growth inducements in the area, in part due to public facilities and
utilities which have been constructed at a rapid rate in the area..
El Camino Real has recently been improved to accommodate the
increasing traffic in the area. Sewage facilities have been or are
being installed which anticipate the use of the property for
residential use. The Leucadia County Water District is in the process
of having additional facilities built at its treatment and pumping
plant site at the intersection of La Costa Avenue and El Camino Real.
The offsite sewer line which is required by this project will have
a growth inducing impact on the areas to the south and east of the
project. Construction of this offsite sewer will provide sewer service
24
closer to areas which were previously undeveloped, making off site
sewer requirements for these undeveloped properties less extensive,
25
C
H. THE BOUNDARIES OF THE AREA WHICH MAY BE SIGNIFICANTLY
AFFECTED BY THE PROPOSED ACTIVITY
The boundaries of the areas which are affected by the project
are dependent on the environmental effect being considered. The
effects of traffic generated by this project and its air and noise pollution
problems are probably limited to a three mile range. Beyond that limit,
the traffic is sufficiently dispersed so that the effects would be negligible
The effects of the project on the biological component of the
environment will generally be limited to the immediate vicinity of the
project site, but may range as far as the Batiquitos Lagoon. The area
affected by the changed visual appearance of the project site will be
limited by the ridges to the north,south and east.
