Reference: Results of the Biological Survey for the Hillside Drive Residence Project, Carlsbad, California
(RECON Number 9228)
Dear Mr. Smith:
A biological survey was conducted within the proposed site for the Hillside Drive Residence Project (project
boundary) to determine the potential for sensitive biological resources. The purpose of this letter is to
provide information on the current condition of the biological resources within the project boundary and an
assessment of potential impacts and mitigation of the proposed project in accordance with federal, state, and
local laws and regulations.
Introduction
The proposed project would construct a private residence located at 4246 Hillside Drive in the city of
Carlsbad, California (Figure 1). The project boundary is located in an unsectioned portion of the Agua
Hedionda Land Grant in Range 4 West, Township 12 South, of the San Luis Rey Quadrangle U.S. Geological
Survey topographic map, and consists of .a 0.26-acre undeveloped lot surrounded by development (Figures 2
and 3). The project boundary is also located within the boundaries of the final Multiple Habitat Conservation
Plan (MHCP), which is a multi-jurisdictional habitat conservation plan that was prepared for seven north
San Diego County jurisdictions: Oceanside, Carlsbad, Encinitas, San Marcos, Vista, Solana Beach, and
Escondido (San Diego Association of Governments [SANDAG] 2003). More specifically, the project site falls
within the City of Carlsbad's MHCP Subarea Plan, which is the City of Carlsbad's Habitat Management
Plan (HMP). The project boundary is not within or adjacent to a HMP Preserve Area (Figure 4).
Methods
RECON biologist Cailin Lyons conducted a general biological survey of the project boundary on July 27,
2018. Prior to conducting surveys, species occurrence records in the California Natural Diversity Database
(CNDDB) from within two miles were reviewed. Vegetation communities were mapped on al-inch-equals-
25-foot aerial photograph flown in 2018. Vegetation community classifications follow Oberbauer et al. (2008),
which are based on Holland's 1986 Preliminary Descriptions of the Terrestrial Natural Communities of
California. All plant species observed on-site were also noted, and plants that could not be identified in the
field were identified later in the laboratory using taxonomic keys. The survey also included a directed search
for sensitive plants and wildlife that would have been apparent during the time of the survey. The project
boundary was assessed for potential sensitive biological and aquatic resources, including sensitive
vegetation communities, wetlands/waters, plants, and wildlife. Assessments for the potential occurrence of
sensitive species are based upon known ranges, habitat preferences for the species, and species occurrence
records from the CNDDB (State of California 2018).

Survey Results
Physical Characteristics
The project boundary occurs in an undeveloped lot in a neighborhood in Carlsbad, California. The
undeveloped lot shows evidence of recent grading and vegetation removal within a portion of the site. The
project site is bounded by private residences to the north and south, with a landscaped slope and residence
to the north, and Hillside Drive to the south (see Figure 3). The project boundary is further surrounded by a
mosaic of residential development and undeveloped lots.
One soil type, Corralitos loamy sand (5 to 9 percent slopes), is mapped within the project boundary.
Corralitos loamy sand consists of somewhat excessively drained, very deep loamy sands. This soil type is
formed in alluvium derived from marine sandstone and is typically located in narrow valleys and on small
alluvial fans (U.S. Department of Agriculture 1973).
Biological Resources
The project boundary contains two land cover types: disturbed land and urban/developed (Table 1; Figure 5;
Photographs 1 and 2). The urban/developed consists of an unvegetated area that was recently graded prior
to the biological survey. The disturbed land consists primarily of bare ground with ripgut grass (Bromus
diandrus), castor bean (Ricinus communis), chrysanthemum (Chrysanthemum sp.), and ice plant
(Ca,pobrotus edulis). Some scattered native shrubs, such as lemonade berry (Rhus integrifolia), laurel
sumac (Malosma laurina), and coastal California buckwheat (Eriogonum fasciculatum var. fasciculatum)
occur intermixed with the non-native vegetation but generally provide low cover and provide low habitat
value due to the isolated nature of the site. Based on aerial photography and street imagery, the
Urban/Developed land appears to have had similar vegetation composition as the Disturbed Land prior to
the recent grading activities.
Table 1
Existing Land Cover Types
within the Project Boundary
Land Cover Tvoes Acreage
Disturbed Land 0.13
Urban/Develooed 0.13
TOTAL 0.26
A total of 13 plant species were identified within the project boundary. Of these plant species, four are
considered native and nine are considered non-native. A complete list of the plant species identified within
the project site is shown in Table 2. In addition, one wildlife species, honeybee (Apis mellifera) was identified
within the project site at the time of the survey.
Sensitive Biological Resources
The presence of sensitive biological resources and their potential for occurrence were evaluated within the
project boundary. No sensitive biological resources, including sensitive plants or wildlife, were identified at
the time of the survey. Furthermore, no sensitive plants are anticipated to occur due to high levels of
disturbance within the project boundary (e.g., visible soil disturbance and prevalence of non-native species).
One sensitive wildlife species, California horned lark (Eremophila alpestris actia), has moderate potential to
nest within the disturbed habitat within the project site. Additionally, there is potential for nesting of
migratory birds to occur within the project boundary. The potential for sensitive plants and wildlife within
the project boundary are discussed further in Attachments 1 and 2.

The proposed project would impact a total of 0.13 acre of disturbed land and 0.13 acre of urban/developed
(Figure 6). Impacts to disturbed land and urban/developed are not considered significant, as these land cover
types are not considered sensitive biological resources. Although these land cover types are not considered
sensitive, mitigation is required by the City of Carlsbad's HMP for impacts to disturbed land. The
urban/developed land that was previously graded will also require mitigation, as it was likely comprised of
disturbed land prior to grading.
No direct impacts to sensitive plant are expected to occur, as no sensitive plants were identified within the
project boundary and none are expected to occur. There is a potential for direct and indirect impacts to
migratory or nesting birds, including California horned lark, within the project boundary should vegetation
removal and/or grading occur during the general bird breeding season (February 15-September 15).
Mitigation for potentially significant direct impacts to nesting and migratory birds are required under the
California Fish and Game Code 3503 (California Department of Fish and Wildlife 1991).

Mitigation
Mitigation is required for impacts that are considered significant under the California Environmental
Quality Act. All impacts to sensitive biological resources should be avoided to the maximum extent feasible
and minimized when possible. Mitigation for potential impacts to land cover types and nesting birds,
including California horned lark, are discussed in further detail below.
Sensitive Biological Resources
Vegetation Communities/Land Cover Types. Prior to the issuance of any permits for land disturbance or
grading, the project applicant shall pay the per acre in lieu mitigation fee to the City of Carlsbad for impacts
to 0.13 acre of disturbed land (including the 0.13 acre of urban/developed that was previously graded).
Nesting Birds. To conform to the California Fish and Game Code, no impacts shall occur to any nesting birds
or their eggs, chicks, or nests during the breeding season (i.e., February 15-September 15). If vegetation
removal and/or grading are proposed during the bird breeding season, a qualified biologist shall conduct a
survey for active nests within the project boundary and an addition 500-foot survey buffer within three days
of construction. If nests of sensitive birds or migratory birds are located, they will be fenced with a protective
buffer of at least 500 feet from active nests of listed species, and 300 feet from other sensitive bird species
(City of Carlsbad 2008). All construction activity will be prohibited within this area.
Conclusion
The aforementioned mitigation measures would mitigate potential impacts to vegetation communities,
horned lark, and nesting birds to below a level of significance. For any questions related to this biological
report, please contact me at (619) 308-9333 ext. 130 or clyons@reconenvironmental.com.

ESRA shall be protected against significant disruption
of habitat values. Only uses dependent on those
resources shall be allowed within those areas. ESRA is
defined as "any area in which plant or animal life or
their habitats are either 1·are or especially valuable
because of their special nature or role in an ecosystem
and which could be easily disturbed or degraded by
human activities and developments.
Conserve a minimum of 67% of the coastal sage scrub
habitat and 75% of the gnatcatchers on-site.
No impacts to wetlands are allowed except where
stated in California Public Resources Code Section
30233.
If impacts to wetlands a.re allowed, mitigation shall be
provided at a ratio of 3: 1 for riparian impacts and 4: 1
for impacts to saltwater or freshwater wetland, or
marsh
A no net loss standard applies to coastal sage scrub,
maritin1e succulent scrub, southern maritime
chaparral, southern mixed chaparral, native
grassland, and oak woodland. Mitigation shall include
a creation component that achieves the no-net-loss
standard. Substantial restoration may be substituted
for creation if approved by wildlife agencies and
California Coastal Commission.

The project site consists of two non-sensitive
land cover types: disturbed land and
urban/developed, and is restricted by
residential development on all sides. No
sensitive plant or wildlife species were
observed at the time of the survey. Though
the project site has potential to supp01t one
sensitive species that is adapted to disturbed
lands, California horned lark (Eremophila
alpestris), the project site as a whole
provides low habitat value. As such, the
project site would not meet the c1·iteria for
ESRA as defined in the California Coastal
Act and thus complies with this standard.
The project site does not contain coastal sage
scrub habitat; thus, the project meets this
standard.
The project site does not contain wetlands;
thus, the project meets this standard.

Mitigation will typically include creation at a ratio of

mitigation credit in the Coastal Zone. On-site or off-
site areas may be used for mitigation if habitat is
disturbed and suitable for 1·esto1·ation 01· enhancement,
or if habitat is devoid of habitat value and therefore
eligible for the 1: 1 creation/substantial restoration
mitigation component. Mitigation should be provided
within the Coastal Zone. Refer to 7-9 for more details,
including mitigation ratios and habitat creation
requirements (summarized in Table 6 below)
(a) If more than 80% of property is covered with ESHA,
at least 75% of the pmperty shall be conserved, OR (b)
If the City approves a hardline preserve bounda1-y for
these properties as part of the Habitat Management
Plan, the amount of on-site prese1·vation as identified
in the hardline boundary will apply.
Mininrnm buffers between all preserved habitat and
development are (a) 100 feet for wetlands; (b) 50 feet
for riparian areas; (c) 20 feet for native uplands
No development, grading, or alteration shall occur
within a buffer except (a) Fuel modification in Zone 3
to max of 20 feet fo1· upland and non-riparian habitat,
and not within 50 feet of riparian, wetland or oak
woodland habitat; (b) some recreational trails and

Proiect Comnliance
The project site is comprised of disturbed
land and urban/developed, which is not
considered a sensitive habitat type requiring
the creation or restoration of habitat. The
project will comply with the fee in lieu
requirement for disturbed lands, as detailed
in the project's mitigation.
The pmject site does not contain ESHA 01· a
Habitat Management Plan hardline preserve
boundary that would require on-site
preservation. Thus, the project is consistent
with this standard.
The project site is not adjacent to any
wetlands, riparian, oak woodland, 01· native
upland habitat that would requii·e a buffet
area. Thus, the project is consistent with this
standard.

See model grading ordinance in Carlsbad Maste1·
Drainage Plan; (a) Grading in the Coastal Zone has
generally been prohibited during the rainy season,
October 1 to Ap1·il l; (however, pursuant to revisions to
the City Zoning Ordinance processed through a Local
Coastal Plan Amendment, grading is allowed if
appropriate Best Management Practices (BMPs) are
established); (b) All graded areas will be landscaped by
October 1 to reduce el'Osion. Exceptions to these
guidelines may be approved as described in 7-12. For
example, habitat should not be cleared during the bird
breeding season (September 15 -March 15) unless
birds are cleared from the habitat fi.l'St.
The following pl'Operties have parcel specific
standards: (a) city owned lands adjacent to Macario
Canyon and Veterans Memorial Park, and (b) specific
parcels in Zones 20 and 21 that are located within
biological core and linkage areas; see Habitat

grading plans, as approved by the City of
Carlsbad.
The project site does not consist of city
owned lands adjacent to Macario Canyon or
