I. INTRODUCTION
This biological technical report describes existing biological conditions on the PAR 62 Project site. This
report provides the project applicant, City of Carlsbad, U.S. Fish and Wildlife Service (USFWS), California
Department of Fish and Game (CDFG), and U.S. Army Corps of Engineers (ACOE), and the public with
information necessary to assess impacts to biological resources from the project under the California
Environmental Quality Act (CEQA), state and federal Endangered Species Acts (ESAs), the federal Clean
Water Act, the California Fish and Game Code, and the City of Carlsbad's Draft Habitat Management
Plan (HMP).
A. PROJECT LOCATION AND DESCRIPTION
The study area is an approximately 62.3-acre site situated in the City of Carlsbad, in northwestern San
Diego County, California (Figures 1 and 2). It is located north of Palomar Airport Road, south of the
Carlsbad raceway, and west of Business Park Drive.
The proposed project would develop the entire property with the exception of 1.7-acres of open space set
aside for a wildlife corridor on the eastern end of the property. Proposed development includes
structures for an industrial complex and associated access roads. Additionally, a portion of the proposed
extension of Melrose Drive is planned to pass through the west side of the property. Access onto the
property will be possible from Palomar Airport Road, just to the south of the property, as well as from
the proposed extension of Poinsettia Lane, to the north of the property (fold out map).
B. SITE DESCRIPTION
The east and west portions of the PAR 62 property are relatively flat with some rolling hill topography
along the margins of the property. The majority of the site has been previously disturbed by repeated
discing for agricultural purposes and is currently dominated by non-native annual grasses and weeds.
The central portion of the property contains several small naturally-vegetated ravines. Several small
patches of natural vegetation also remain along the eastern fence line. On site elevations range from
approximately 360 feet to 450 feet.
In the context of the Draft HMP, the PAR 62 site is located within Local Facility Management Zone
(LFMZ) 18 (Figure 3). The Linkage D PPA, which goes through the far eastern portion of the PAR 62 site,
links the Core 5 PPA, to the northwest of PAR 62, with the Core 6 PPA to the southwest. This linkage is

present on site as 1.7 acres of open space and connects with linkage areas on the Carlsbad Raceway
Property to the north and, after crossing the Palomar Airport Road, the Rancho Carrillo Property to the
south.
C. SOILS
Three main soil types are present on site (Bowman 1973). Altamont clays occur on the rolling hills of the
western portion of the site. Las Flores loamy fine sand occurs in the eastern area of the property.
Altamont clay is present in the central, undisturbed portion of the site containing Diegan coastal sage
scrub and other habitats. Las Flores loamy fine sand has been described as being potentially hydric soil
in flood plains and depression areas respectively (USDA 1992). Soil depressions are known to occur on
site.
II. METHODS
A total of five site visits have been conducted by HELIX Environmental Planning, Inc. (HELIX) from May
through July 1998 for vegetation mapping, general zoological and botanical surveys, a rare plant survey,
mapping jurisdictional drainages, and focused surveys for the coastal California gnatcatcher (Table 1).
Field work was conducted by Deborah Pudoff, Fred Sproul, Sally Trnka, Larry Sward, and Barry Jones.
Site descriptions are based on these surveys. Vegetation was mapped on a topographic map of 1" = 80'
scale. A1" = 4500' aerial photograph was used on site as a reference.

Zoological survey techniques included searching all habitats for potential wildlife species and noting
species presence or evidence of presence (for example by tracks or scat). Potentially occurring sensitive
plant and animal species were determined by referencing the habitat types present on the project site
with the known distribution of sensitive species in the City of San Diego. Three U.S. Fish and Wildlife
Service protocol surveys were conducted for the coastal California gnatcatcher in the study area (USFWS
1997). Gnatcatcher habitat was surveyed on foot, and taped vocalizations of a gnatcatcher were played
intermittently to elicit response from gnatcatchers, if present.
The wetland delineation followed methods prescribed by the ACOE (Environmental Laboratory 1987).
Drainages were identified on site during vegetation mapping. Non-vegetated Waters of the U.S. present
within the drainages were mapped on June 9,1998. The mapping was conducted by walking along the
drainages and recording channel widths at regular intervals. The widths of drainages in densely
vegetated areas were estimated by noting channel width upstream and downstream of the upland
vegetation. Complete details of the wetland delineation methods and results are provided in a separate
wetland delineation report.
Nomenclature for this report is from Holland (1986) for vegetation communities; Hickman, ed. (1993) for
plants; Collins (1990) for reptiles and amphibians; the American Ornithologist's Union (1983, as updated)
for birds; and Jones et al. (1992) for mammals. Sensitive animal and plant status is taken from the
California Department of Fish and Game (CDFG) (1994a) and CDFG (1994b), respectively (as updated).
III. EXISTING CONDITIONS
A. VEGETATION
The site supports three vegetation communities: Diegan coastal sage scrub, southern mixed chaparral and
non-native grassland (fold out map; Table 2). A large portion of the property has been previously disced
for agricultural purposes and currently exists as disturbed land.

Diegan Coastal Sage Scrub
Diegan coastal sage scrub is a vegetation community characterized by subshrubs with relatively shallow
root systems and open canopies. On site dominant shrubs include California sagebrush (Artemisia
californica), black sage (Salvia mellifera), California buckwheat (Eriogonum fasciculatum) and monkeyflower
(Mimulus aurantiacus). Approximately 3,2 acres of Diegan coastal sage scrub occur on site within the
central portion of the property.
Southern Mixed Chaparral
Southern mixed chaparral is composed of broad-leaved sclerophyllous shrubs that grow to about six to
ten feet tall and form dense often nearly impenetrable stands. This habitat occurs on dry, rocky, often
steep north-facing slopes with little soil. On site southern mixed chaparral is dominated by scrub oak
(Quercus dumosa). Other species present include lemonadeberry (Khus integrifolia), toyon (Heteromeles
arbutifolia), monkeyflower, California adolphia (Adolphia californica) and chamise (Adenostoma
fasciculatum). Approximately 3.3 acres of this habitat occur on site.
Non-native Grassland
Non-native grassland is a dense to sparse cover of annual grasses, often associated with numerous
species of showy-flowered native annual forbs. This association occurs on gradual slopes with deep, fine-
textured, usually clay soils. Characteristic species include wild oats (Avena sp.), bromes (Bromus sp.), and
mustard (Brassica sp.). Non-native grasslands are also important foraging areas for raptors and other
sensitive animal species. Approximately 0.4 acre of non-native grasslands occurs on site.
HELIX
Biological Technical Report for tlie PAR 62 Property /PRC-01 /January 15, 3999
Disturbed Habitat
A majority of disturbed areas include ruderal vegetation dominated by exotics, annual forbs, and grasses.
Other disturbed areas are devoid of vegetation as a result of soil compaction or past grading. Disturbed
habitat on site occurs in areas that were previously disced as well as on dirt roads. This habitat is
generally sparsely vegetated and is dominated by non-native grasses such as wild oats and other exotic
annuals such as mustard and thistle. This habitat is not considered non-native grassland because of the
high composition of weedy annuals. Approximately 55.4 acres of disturbed habitat occur on site.
Drainages
In addition to the vegetation types, several drainages containing ACOE jurisdictional non-vegetated
Waters of the U.S. exist on the property. The drainages extend from the surrounding disturbed slopes
through the naturally-vegetated small canyons in the center of the site. Approximately 0.08 of an acre of
drainages occurs on site. Measurements of the drainages are shown on the attached fold out map of
vegetation and sensitive resources.
B. SENSITIVE SPECIES
High-interest species include those listed by the USFWS (1990), CDFG (1994a, b), and California Native
Plant Society (CNPS) (Skinner and Pavlik 1994). Sensitive species are those considered unusual or limited
in that the species are: 1) only found in the San Diego region; 2) a local representative of a species or
association of species not otherwise found in the region; or 3) severely depleted within their ranges or
within the region.
The Multiple Habitat Conservation Plan (MHCP) (SANDAG 1997) has identified a group of priority
animal species, which includes those listed or proposed for listing at the state or federal levels or that
were designated as Natural Community Conservation Program (NCCP) target species. The City of
Carlsbad Draft HMP (Carlsbad HMP 1997) is consistent with the goals and standards of the MHCP and
for its planning purposes has divided species into four groups based on the authorizations and
assurances that the City is seeking from the USFWS and CDFG. The four HMP species groups are
divided as follows:
HELIX
Biological Technical Report for the PAR 62 Property /PRC-01 /January 15,1999
Group 1 includes already listed species and species currently proposed for listing for which the City is
seeking:
• citywide authorization for take, and
• approval of the plan as mitigation for all impacts to the species from projects covered by the
HMP.
Group 2 includes non-listed species for which the City is seeking:
• approval of the plan as mitigation for all impacts to the species from projects covered by the
HMP, and
• assurance that citywide authorization for take will automatically be given if the species are listed
in the future.
Group 3 includes non-listed species for which the City is seeking:
• approval of the HMP as a mitigation for impacts to the species' foraging habitat, and
• to the degree that impacts to foraging habitat might constitute take under existing federal
regulations, authorization for such take (direct harm to the species and impacts to nest sites
would not be covered).
Group 4 includes species:
• that the City may propose for inclusion in Group 1,2, or 3, and
• for which implementation of the HMP measures is intended to be advance mitigation for future
impacts from projects within the City.
The following subsections describe the sensitive plant and animal species observed on site and their
federal, state, MHCP, and HMP listings (as applicable).

Plants
General botanical and rare plant surveys were conducted on May 28, 1998 (Table 1). A total of ninety
plant species were observed on site during the surveys (Appendix A). Sensitive plant species observed
on site include Nuttall's scrub oak (Quercus dumosa), California adolphia (Adolphia californica) and
Western dichondra (Dichondria occidentalis). These species occurred in the southern mixed chaparral
habitat on site. None of these species are listed as endangered or threatened by the CDFG or USFWS.
Nuttall's scrub oak is an HMP Group 4 species (Carlsbad HMP 1997). None of these species are listed as
endangered or threatened by the CDFG or USFWS.
Nuttall's scrub oak (Quercus dumosa)
Status: Regionally Sensitive/CNPS List IB; R-E-D 2-3-2/HMP Group 4 species.
Distribution: Baja California, Mexico and San Diego, Orange, and Santa Barbara counties in California.
Habitat(s): Chaparral, coastal scrub with sandy or clay loam soils.
Status on site: It is estimated that approximately 2,000 individuals are present throughout the southern
mixed chaparral community on site.
California adolphia (Adolphia californica)
Status: CNPS List 2; R-E-D 1-2-1.
Distribution: Below 1,000 feet in elevation in western San Diego County and northwestern Baja
California, Mexico.
Habitat(s): Clay soils in dry canyons and washes in coastal sage scrub and chaparral.
Status on site: Approximately 25 individuals occur in small patches throughout the southern mixed
chaparral community on site.
Western dichondra (Dichondra occidentalis)
Status: Regionally Sensitive/CNPS List 4; R-E-D 1-2-1
Distribution: Santa Barbara County to Baja California, Mexico and on San Miguel Island.
Habitat(s): Dry, sandy banks in coastal sage scrub, chaparral, or southern oak woodland; often
proliferates on recently burned slopes.
Status on site: A small population of this species was observed in the southwest corner of the southern
mixed chaparral community on site.
In addition to the species listed above, nineteen plant species have the potential to occur on site
(Appendix B). This list is based on habitat types present on site and the distribution of sensitive plant
species in the City of Carlsbad.
Animals
General zoological surveys were conducted on June 24 and July 9,1998 (Table 1). A total of twenty-one
animal species were observed or detected on site during site surveys (Appendix C). The only sensitive
species observed on site was the white-tailed kite (Elanus leucurus). No coastal California gnatcatchers
were observed during focused surveys for these species.
HELIX ,
Biological Technical Report for tlie PAR 62 Property /PRC-01 /January 15,1999 1
White-tailed kite (Elanus leucurus)
Status: Nesting—CDFG Special Animal.
Distribution: Breeds in the Pacific U.S. Winters to South America as far south as Chile.
Habitat(s): Nesting typically occurs in riparian or oak woodlands adjacent to grasslands where small
mammals are hunted.
Status on site: Two individuals were observed hunting over the site.
In addition to the species observed, twenty-two sensitive animal species have the potential to occur on
site, including two federally listed species, the coastal California gnatcatcher (Polioptila californica
californica) and the Quino checkerspot butterfly (Euphydryas editha quind) (Appendix D). This list is based
on habitat types present on site and the distribution of sensitive plant species in San Diego County.
IV. REGIONAL CONTEXT
The significance of biological resources occurring within the Project site are assessed based on the species'
or habitats' importance to the region as a whole, relative quality, and degree of connection to larger open
space or preservation areas. This section presents biological resource issues within the broader context of
the region including considerations such as corridors and preserve design.
A. MHCP,HMP AND NCCP EVALUATIONS
One of the primary objectives of large scale planning efforts such as the MHCP (and the subarea HMP) is
to create a preserve system which allows animals and plants to maintain their existence at both local and
regional levels. The preserve system will be a network composed of core biological resource areas (large
blocks of habitat) and linkages/wildlife corridors. The City of Carlsbad's Draft HMP is consistent with
the goals, standards, and guidelines of the subregional MHCP.
A habitat evaluation model was created for qualifying the lands within the HMP. Qualitative values
were assigned to habitats according to a number of parameters including wildlife, vegetation, and
biogeography. Using this information, the HMP has identified core biological resource areas which are
large blocks of native habitats having the ability to support diverse plant and animal life. Linkages also
provide movement between the core areas. These linkages usually occur in river valleys or along stream
courses, but they can also cross hillsides. The system of evaluating habitats can be used to prioritize
which sites have the highest biological value.
HELIX
Biological Technical Report for tlie PAR 62 Property /PRC-01 /January 15,1999 8
In the context of the Draft HMP, the site is located within Local Facility Management Zone (LFMZ) 18.
The Core 5 Preserve Planning Area (PPA) is located to the northwest of the site. The Linkage D PPA,
which goes through the far eastern portion of the PAR 62 site, links the Core 5 PPA with the Core 6 PPA
to the southwest. This linkage is present on site as 1.7 acres of open space and connects with linkage
areas on the Carlsbad Raceway Property to the north and, after crossing the Palomar Airport Road, the
Rancho Carrillo Property to the south.
The NCCP Process Guidelines provide an evaluation logic flow chart for defining the long-term
conservation potential of sage scrub habitat (CDFG and California Resources Agency 1993). Following
this flow chart, sage scrub is present on the Project site, but does not comprise the densest sage scrub
habitat in the subregion. Areas such as the Chang property to the northwest support large contiguous
blocks of high quality sage scrub habitat within the same region as the Project. However, the Project does
provide a key linkage between areas of high habitat value to the northwest and to the south. No
significant populations of target species are present on site. The guidelines define a significant
gnatcatcher population as any area having five or more pairs. The Project site does not appear to support
any gnatcatcher pairs. Therefore, the site does not qualify as a high value district, but on-site habitat is
considered to have a moderate potential for long-term conservation.
B. RESOURCE SPECIFIC ANALYSIS
The most significant resources on site are the non-vegetated Waters of the U.S. and the Diegan coastal
sage scrub in the central portion of the property. Impacts to these habitats are regulated by federal and
state law.
Individual sensitive plant species may sometimes be considered significant, depending upon population
numbers on site and relative abundance in the species' ranges. None of the plant populations found on
site are considered significant because of their small population size and/or lower sensitivity.
Additionally, the sensitive bird species found on site is of low sensitivity and is not considered
significant.
C. REGULATORY ISSUES
Regulations that apply to the Project include the federal Endangered Species Act (ESA), California Fish
and Game Code, federal Clean Water Act, and California Environmental Quality Act (CEQA). The
HELIX
Biological Technical Report for the PAR 62 Property /PRC-01 /January 15,1999 ?
federal ESA provides the legal framework for protection of species (and their habitats) which are
identified as being in danger of extinction or which are threatened at a regional level. Impacts to
protected species (those listed as endangered or threatened) are considered a take under the federal ESA.
For purposes of the federal ESA, if gnatcatchers are present on a site, then contiguous and nearby suitable
habitat is generally considered to be "occupied" as well. Additionally, all Diegan coastal sage scrub
occurring within jurisdictions enrolled in the NCCP, including the City of Carlsbad, is considered
occupied habitat. Any impact to occupied habitat would normally be considered a take under the federal
ESA which is prohibited except by appropriate permit by the USFWS.
The ACOE regulates impacts to jurisdictional Waters of the U.S. including wetlands. Jurisdictional
wetlands are defined by areas which meet ACOE standards for hydrology, vegetation, and soils. The
"waters of the U.S." on site are jurisdictional, and any alteration to them would be subject to regulation
by the ACOE in the form of a permit pursuant to Section 404 of the federal Clean Water Act. The CDFG
also regulates impacts to the drainages on site under Section 1600 of the Fish and Game Code. A section
401 certification/waiver from the California Regional Water Quality Control Board is also required for
impacts to drainages.
V. IMPACTS
Two types of impacts will be assessed in the following subsections: direct and indirect. Analysis of
project impacts was based on limits of grading. All fuel modification is assumed to occur within the
areas proposed for permanent development.
Direct impacts are those that immediately alter the affected biological resources such that those resources
are not expected to recover to their pre-impacted state. An assumption of this impact assessment is that
all areas within the "edge of disturbance," as defined by the grading limits for the project, will be
interpreted as direct impacts.
Direct impacts resulting from the project total 60.6 of the 62.3 acres on site (fold out map, Table 3). The
majority of these impacts are to disturbed (55.4 acres) areas. Native habitats impacted include southern
mixed chaparral (3.3 acres), Diegan coastal sage scrub (3.2 acres), and non-native grassland (0.4 acre).
Impacts to Diegan coastal sage scrub are considered significant.

All of the Nuttall's scrub oak, California adolphia, and western dichondra will be lost as a result of the
project. These impacts are considered adverse but not significant.
Some loss of foraging habitat for raptors will occur as a result of the project. This impact is considered
adverse but not significant.
Indirect impacts are impacts to the biological resources that occur over short or long periods of time due
to the project action. Although biological resources may not initially be directly impacted, over time they
may be affected indirectly due to the relative proximity of development. Examples of indirect impacts
include habitat insularization, edge effect, exotic species invasion, domestic pets, increased human
intrusion, lighting, and noise impacts. Indirect impacts associated with this project based on proposed
land uses will be primarily habitat insularization, the potential for exotic species invasion, and lighting
impacts.
The project would potentially constrict wildlife movement across the site. A corridor with a minimum
width of 400 feet will be provided to insure continued wildlife movement consistent with the Draft HMP.
Impacts to wildlife movement are considered adverse but not significant.
HELIX
Biological Technical Report for the PAR 62 Property /PRC-01 /January 15,1999
VI. MITIGATION
The mitigation program is currently being developed through ongoing discussions with the resource
agencies and city staff. Outlined below are general guidelines currently being considered.
All impacts to Waters of the U.S. will be mitigated at a minimum 1:1 replacement ratio. Mitigation will
occur off site within the area identified as potential preserve area by the HMP. One potential off-site
mitigation area is the Carlsbad Raceway property immediately to the north. Diegan coastal sage scrub
will be mitigated by on-site restoration of the wildlife corridor and by off-site preservation or mitigation
in an area identified as potential preserve area by the HMP.
The mitigation measures outlined above will mitigate all impacts to biological resources to below a level
of significance.
