REPORT OF A BIOLOGICAL SURVEY
GOLD COAST PROPERTIES, LLC
CARLSBAD
SAN DIEGO COUNTY, CALWORNIA
8 May 1996
EXECUTIVE SUMMARY
... A general biological survey of the 1.95-acre Gold Coast Properties, LLC site found
three vegetation communities: 0.55 acre of disturbed coastal sage scrub, 0.77 acre of
non-native grassland, and 0.45 acre of ruderal. The remaining 0.18 acre within the
study area has been disturbed by a singlefamily home and driveway.
The 0.55 acre of disturbed coastal sage scrub is a sensitive and regulated vegetation
community. One sensitive plant species was detected during the survey: California
adolphia (Adolphia calfomica). Forty six species of plants were found on-site (excluding
most cultivars). Forty eight percent of the floral species were non-natives. No sensitive
animals were detected during the survey, furthermore, no amphibians, reptiles, or
mammals were detected on the property. Eleven birds utilized the site during the
general survey.
The Gold Coast Properties, LLC’s development of the site will have a direct, significant
impact on approximately 0.55 acre of disturbed, low-moderate quality coastal sage
scrub. This significant direct impact is mitigatable. The California adolphia sparsely
scattered throughout the 0.55 acre of disturbed coastal sage scrub will be directly
impacted. This is an adverse but less than significant direct impact.
The preferred mitigation recommendation is the creation of a conservation easement
for the 0.55 acre of disturbed coastal sage scrub. The alternative mitigation is the off-site
purchase and preservation of coastal sage scrub.
1.0 INTRODUCTION
At the request of Gold Coast Properties, Pacific Southwest Biological Services, Inc. (Pacific Southwest)
conducted a general biological survey of the 1.95-acre site within the City of Carlsbad. This report
includes the findings of the biological survey, professional discussions, and a literature review. The
report also provides an analysis of the direct and indirect impacts to sensitive biological resources (on
and/or adjacent to the site) and the recommended mitigation measures to reduce all impacts to below
a level of significance.
2.0 PROJECT LOCATION
05/08/96 Pacific Southst Biological Services, Inc.
PSBS #T161 2
"
2.0 PROJECT LOCATION
"
The project site is located within the United States Geological Survey OJSGS) 7.5' Quadrangle of San
Luis Rey, San Diego County, City of Carlsbad, approximately 1 mile east of the Pacific Ocean and 0.57
mile east of Interstate 5, along the northern shore of Agua Hedionda Lagoon (Figures 1 & 2).
-:~ 3.0 PROJECT DESCRIPTION
Gold Coast Properties, LLC proposes an extensive remodelling and relandscaping of an existing, older,
singlefamily residence. The find plans are not complete.
4.0 SITE PHYSICAL CONDITIONS
4.1 Topography and Soils
The project site is within the immediate coastal portion of the City of Carlsbad. The property is a
combination of a low hill with moderate slopes and nearly flat terrain. The site ranges in elevation
from 47 feet above mean sea level atop the low hill where the house sits to approximately 9 feet at the
site's southern corner.
Soil types mapped as present on the existing parcel include the following members of the Marina and
Las Flores soil series (Bowman 1973):
..,
0 Marina loamy coarse sand, 9 to 30 percent slopes
0 Las Flores-Urban Land Complex, 2 to 9 percent slopes.
- 4.2 Land Uses
All of the site has been disturbed to some degree. In the past, agricultural crops were grown on the
flat land along the eastern border of the site. An older, occupied residence sits atop a pad on the
- property's hill and is surrounded by a mowed and watered "lawn".

5.0 SURVEY METHODS AND LIMITATIONS ._
The biological survey was conducted by Marcia Dustin Mann on 29 April 1996. Ail portions of the
site were walked. The vegetation communities and sensitive resources were mapped onto a 1" = 20'
scale, topographic map.
The scientific nomenclature used in this report is from the following standard references: vascular plants
(I-bckman 1993; Munz 1974; Beauchamp 1986),vegetation communities (Holland 1986), wildlife habitats
(Mayer, et af. 1988), amphibians and reptiles (Jennings 1983 and Stebbins 1966), birds (American
Ornithologists' Union 1983, 1989), and mammals (Jones, et ai. 1992).
6.0 EXISTING CONDITIONS
6.1 Vegetation Communities
Vegetation types or communities are assemblages of plant species that usually coexist in the same area.
The classification of vegetation communities is based on the life form of the dominant species within
that community and the associated flora. The vegetation types follow that of Holland (1986). In some
instances, there may be an assemblage of plant species for which there is not an adequate description
in this reference. In that case, a category was selected which reflected both the floristics and
physiognomy of that assemblage. There are three vegetation communities that occur within the study
area (Figure 3).
6.1.1 COASTAL SAGE SCRUB (0.55 ACRE)
Coastal sage scrub is one of the major shrubdominated (scrub) communities within California. This
community occurs on xeric sites with shallow soils. Sage scrub species are typically drought-deciduous
plants with shallow root systems. Both of these adaptations allow for the occurrence of sage scrub
species on these xeric sites.
The 0.55 acre of coastal sage scrub on-site has been repeatedly disturbed (Photographs 1 & 2. Appendix
3). Of the three patches of coastal sage scrub on-site, the patch in the northwestern portion of the site
has been the least disturbed (Right Section, Photograph 2. Appendix 3.) The dominant species are

variously California sagebrush (Artemisiacufifomicu), laurel sumac (Mufosma farina), toyon (Heteromefes
arbutiffia), lemonadeberry (Rhus integrifofia), California adolphia (Adofphia cafifomica), San Diego
monkeyflower (Mimufus auruntiacus), and coyote brush (Buccharis pifufuris). The understory is
composed primarily of non-native, annual grasses with a componenet of naiive, perennial grasses in the
less disturbed areas.
6.1.2 NON-NATIVE GRASSLAND (0.77 ACRE)
The 0.24 acre of non-native grassland on the property is dominated by slender wild oat (Avena barbata),
barley (Hordeum mun'num), and ripgut grass (Bromus diandrus). In coastal San Diego County, these
invasive, non-native grasses are indicators of disturbance.
6.1.3 RUDERAL (0.45 ACRE)
Ruderal refers to land recently or regularly disturbed in which the earliest successional species are
dominant. In coastal San Diego County these species tend to be non-native, often invasive, annuals.
On-site the dominant ruderal species are Crete hedypnois (Hedypnois cretica), barley (Hordeum
murinum), white-stem filaree (Erodium moschutum), and pineapple weed (Charnomiffu suaveofens).
6.2 Flora
Forty six species of plants were observed during the surveys. Twenty two of these species,
approximately 48 percent, are plants that are not native to California. The high percentage of non-
native species on-site is expected on disturbed land. See Appendix 1 for a complete floral list. The
horticultural plants on-site were generally not included in the species list.
6.3 Wildlife Habitats
Wildlife habitats differ from vegetation communities since a wildlife habitat may contain several
vegetation communities which will be similar in structure but different in their plant species
composition, location, and soil substrate. This distinction becomes an important factor when assessing
the sensitivity of a particular wildlife habitat. An example of this would be a shrubland habitat

"
composed of a non-sensitive vegetation community (e.g., chamise chaparral) versus a shrubland habitat
composed of a sensitive vegetation community (e.g., coastal sage scrub). I
The disturbed coastal sage scrub on-site is not dense enough to be considered scrub habitat for wildlife.
The entire site is classified as suburban wildlife habitat (Mayer 1988).
6.4 Fauna
Eleven species were observed on-site (Appendix 2).
6.4.1 AMPHIBIANS
No amphibians were observed during the 29 April 1996 survey.
No reptiles were observed during the 29 April 1996 survey.
6.4.3 BIRDS
During the 29 April 1996 survey of the site, 11 species of birds were observed utilizing the property.
A complete list is presented in Appendix 2. Surveys conducted during different times of the year
would undoubtedly encounter additional species, but none of these would be considered to raise
sensitive issues.
"- 6.4.4 MAMMALS
No mammals were observed during the 29 April 1996 survey.

6.5 Wildlife Connectivity
This site's disturbed coastal sage scrub is more or less an isolated patch in the midst of suburban
development. Cove Drive and Multi-story apartment complexes form the northern and eastern
boundary of the property; Adams Avenue and residential homes border to the west; and a soon-to-be-
developed residential parcel lies to the southwest and west. The nearest significant block of coastal sage
scrub is a hillside across Cove Drive to the northeast and behind a row of multi-story apartment
complexes (Photograph 2).
7.0 SENSITIVE BIOLOGICAL RESOURCES
7.1 Sensitive Vegetation Communities
Sensitive habitats are those which are considered rare within the region, are considered sensitive by the
County of San Diego or the California Department of Fish and Game (CDFG), or support sensitive
plants or animals.
7.1.1 COASTAL SAGE SCRUB
Coastal sage scrub is considered a sensitive habitat by several agencies, including, the County of San
Diego (1991 b) and the California Department Fish and Game (Holland 1986) because this community
supports a number of sensitive species. Oberbauer and Vanderwier (1991) estimate that only about
130,000 acres of sage scrub remain in San Diego County. This represents a 69% loss of this community
in the County from the pre-European era. These estimates were based on 1988 vegetation coverage
estimates and additional losses have accrued since. Loss of sage scrub within California is due primarily
to grazing and urbanization.
The 0.55 acre of disturbed coastal sage scrub which occurs on-site is of low-moderate quality due to the
repeated disturbance of the site. The one patch of coastal sage scrub in the northwestern section of the
property is of moderate quality. The other two patches are more distrubed and are of low quality.

7.2 Sensitive Flora
Sensitive flora include those listed by the United States Fish and Wildlife Service (USFWS) and/or
CDFG, candidates for listing by USFWS and/or CDFG, species considered sensitive by CDFG, floral
species considered sensitive by the California Native Plant Society (CNPS), and/or species considered
sensitive by the San Diego Association of Governments (SANDAG). See Appendix 4 for an
explanation of the USFWS, CDFG, and CNPS designations. One sensitive plant species was observed
during the survey (Figure 3). This species and its status on-site are described below.

Coastal San Diego County; Baja California, Mexico
This short shrub is often intermixed with Diegan sage scrub, but occasionally
occurs in peripheral chaparral habitats, particularly hillsides near creeks. The
California Adolphia (sometimes called California Spinebush) is usually associated
with Eriogonum fasciculatum and Artemisia californica in xeric locales where shrub
canopy reaches four or five feet in height. During late summer and fall it may be
virtually leafless.
California Adolphia is still found at a variety of coastal San Diego County locales.
California Adolphia is substantially declining due to urban growth; still healthy
populations are extant. This spiny shrub is sometimes a dominant shrub on
hillsides, and such sites should be protected. Although Adolphia is not uncommon
in southwestern San Diego County, a decade of continued urbanization along the
coast could significantly reduce the populations now extant. California Adolphia
should be considered for native revegetation projects in suitable habitat.
7.3 Sensitive Fauna
Sensitive fauna includes those listed by USFWS and CDFG; candidates for listing by USFWS or
CDFG; species considered sensitive by CDFG; and species considered sensitive by SANDAG. See
Appendix 4 for an explanation of the USFWS and CDFG designations.
No sensitive fauna was detected on-site. Although this site may be within the historical range of the

isolation of the site and the long-time presence of domestic cats makes the likelihood of occurrence
extremely low.
8.0 IMPACT ANALYSIS
Several types of impacts are assessed: direct, indirect, and cumulative.
. ".
8.1 Direct Impacts
Direct impacts are caused by the project activity and occur at the same time and place of the project
activity. These direct impacts can be short-term or long-term.
8.1.1 VEGETATION COMMWWTES
The development of the Gold Coast Properties, LLC site will directly impact approximately 0.55 acre
of coastal sage scrub. Direct impacts to the coastal sage scrub are considered significant due to the
sensitivity of this community.
8.1.2 SENSmvE FLORA
The development of the Gold Coast Properties, LLC site will directly impact the California adolphia
in the disturbed coastal sage scrub. This is an adverse, but less than significant, direct impact.
8.1.3 SENSnrvE FAUNA
No sensitive fauna occurs on-site, and none is expected.
8.2 Indirect Impacts
Indirect or secondary effects are caused by the project activity and are later in time or farther removed
in distance, but are still reasonably foreseeable. Indirect or secondary effects may include related effects
on air and water and other natural systems, including ecosystems. Examples of indirect effects are
05/08/96 Pucific Southwest Biologicul Services, Inc.
PSBS #T161 12
increases in exotic species invasion, increased animal mortality due to increased traffk along roads in
occupied habitats, fugitive dust covering vegetation which results in decreased photosynthetic capacity,
etc.
8.2.1 VEGETATION COMMUNITIES
No indirect impacts to sensitive vegetation communities are likely to occur due to this project.
8.2.2 SENSITIVE FLORA
No indirect impacts to sensitive fauna are likely to occur due to this project.
8.3 Cumulative Impacts
As defined in CEQA, "Cumulative impacts refer to two or more individual effects which, when
considered together, are considerable or which compound or increase other environmental impacts
(CEQA 1970)." An example of a cumulative impact would be the incremental loss of small amounts
of a sensitive habitat occurring as an impact of several adjacent or locally occurring projects. The
individual loss of small amounts of this sensitive habitat may be considered adverse, but not significant,
but the cumulative loss among all of the projects would be considered a cumulatively significant impact.
Cumulative impacts are assessed to determine the long term cumulative effects of project
implementation on biological resources on a regional scale (e.g., incremental habitat or species
reduction).
8.3.1 VEGETATION COMMUNITIES
Direct impacts to the one sensitive habitat, coastal sage scrub, which occurs within the property
boundaries will result in cumulative impacts that are considered cumulatively adverse, but less than
significant.
05/08/96 Pacific Southwest Biological Services, Inc.
PSBS #T161 13

8.3.2 SENSITIVE FLORA
Direct impacts to the one sensitive plant, California adolphia, which occurs on-site will result in a
cumulative impact that is adverse, but less than significant.
9.0 RECOMMENDED MITIGATION MEASURES
The following mitigation measures are recommended to reduce impacts to biological resources from
the proposed development to below a level of significance.
9.1 Sensitive Vegetation Communities
9.1.1 COASTAL SAGE SCRUB
The recommended mitigation for direct impacts to the 0.55 acres of coastal sage scrub is creation of a
conservation easement. An alternative mitigation measure is the off-site acquisition and preservation
of coastal sage scrub. The proposed mitigation replacement ratio for direct impacts to the coastal sage
scrub ranges from 1-2:1, depending upon the quality of the habitat impacted. Since the disturbed
coastal sage scrub on-site is of low-moderate quality, mitigation would likely be a 1:l replacement.
Using the mitigation ratios discussed above, the impacts to the coastal sage scrub would require a total
of 0.55 acre to be purchased and preserved off-site.

G (Global Ranking) The global rank (Grank) is a reflection of the overall condition of an element
throughout its global range.
SPECIES OR NATURAL COMMUNITY LEVEL
G1 Less than 6 viable EOs or less than 1,000 individuals or less than 2,000 acres
G2 6-20 EOs or 1,000-3,000 individuals or 2,000-10,000 acres
G3 21-100 EOs or 3,000-10,000 individuals or 10,000-50,000 acres
G4 Apparently secure; this rank is clearly lower than G3 but factors exist to cause some concern;
i.e. there is some threat, or somewhat narrow habitat.
G5 Population or stand demonstrably secure to ineradicable due to being commonly found in the
world.
SUBsPECIEs LEVEL
Subspecies receive a T-rank attached to the G-rank. With the subspecies, the G-rank reflects
the condition of the entire species, whereas the T-rank reflects the global situation of just the
subspecies.
For example: Chorizanthe robusts var. hartwegii.
This plant is ranked G2T1. The G-rank refers to the whole species range i.e. Chorizanthe
robusts. The T-rank refers only to the global condition of var. hartwegzi.
S (State ranking) The state rank is assigned much the same way as the global rank, except state
ranks in California often also contain a threat designation attached to the S-
rank.
s1 Less than 6 EOs or less than 1,000 individuals or less than 2,000 acres
S1.1 = very threatened
S2.2 = threatened
S3.3 = no current threats known

APPENDIX 4. PLANT AND ANIMAL SENSmVrrY GUIDEUNFS (CONTINUED)
S2 6-20 EOs or 1,000-3,000 individuals or 2,000-10,000 acres S2.1 = very threatened
S2.2 = threatened
S2.3 - no current threats known
. -.
s3 21-100 EOs or 3,000.10,OOO individuals or 10,000-50,000 acres S3.1 = very threatened
S3.2 = threatened
S3.3 = no current threats known
S4 Apparently secure within California; this rank is clearly lower than S3 but factors exist to cause
some concern; i.e. there is com threat, or somewhat narrow habitat. NO THREAT RANK.
S5 Demonstrably secure to ineradicable in California. NO THREAT RANK.
NOTES:
1. Other considerations used when ranking a species or natural community include the pattern of
distribution of the element on the landscape, fragmentation of the populatiodstands, and historical
extent as compared to its modern range. It is important to take a bird’s eye or aerial view when
ranking sensitive elements rather than simply counting EOs.
2. Uncertainty about the rank of an element is expressed in two major ways:
By expressing the rank as a range of values.
For example: S2S3 means the rank is somewhere between S2 and S3.
By adding a n?n to the rank.
For example: S2? represents more certainty than S2S3, but is less than S2.
3. Other symbols
GH All sites are historical; the element has not been seen for at least 20 years but suitable
habitat still exists (SH = All California sites are historical).
GX All sites are extirpated; this element is extinct in the wild (SX = All California sites are
extirpated).
GXC Extinct in the wild; exists in cultivation.
G1Q The element is very rare, but there is a taxonomic question associated with it.

Considered sensitive in San Diego County.
A species or subspecies which has undergone dramatic, non-cyclic, long-
term population declines, to the point where the situation has reached
the critical level throughout their range. Many of these species have
been recognized and protected by state or federal legislation. A species whose local breeding populations have been steadily reduced,
or in some cases extirpated. A species for which declines have not been documented, but are
regarded as sensitive because of: 1) extremely localized or limited
distribution, 2) sensitivity to disturbance, 3) actual or impending
destruction of essential habitat, or 4) lack of sufficient data on current
or past status which significantly increased the potential for serious
reduction of a local population.
Considered sensitive in San Diego County.
Considered sensitive by local biologists. No official status.
