1 SUMMARY OF FINDINGS
This report has been prepared in conformance with the City of Carlsbad's (City) Guidelines for
Biological Studies (TAIC 2008), Habitat Management Plan (City of Carlsbad 2004; HMP), and the
California Environmental Quality Act (CEQA) for the proposed development of nine single-family
homes (project) on a 3.79-acre parcel in the City.
The proposed project could result in a significant impact on sensitive habitats including Diegan
coastal sage scrub, non-native grassland, and eucalyptus woodland and on nesting birds.
However, it is anticipated that incorporation of mitigation measures outlined in Section 5 would
avoid significant impacts on these resources.
The-project site is within the City's HMP area. The project site is not within or adjacent to an
existing or proposed hardline or standards area as defined in the City's HMP and is not within the
Coastal Zone. The Project site does not support state and/or federally listed plants, animals, or
jurisdictional wetlands or other Waters of the U.S.
2 Introduction
The project site is located at 2200 Afton Way in the City and is bordered by Carlsbad Village Drive
on the north and residential housing on the east, south, and west. There is an existing home and
associated outbuildings on the 3.79-acre site that are no longer occupied or used. The proposed
project consists of razing the existing structures, clearing of vegetation, grading, and construction
of nine single-family homes on 10,000 square-foot minimum lots.
3 METHODS AND SURVEY LIMITATIONS
This study included the following activities:
• Review of City Guidelines for Biological Studies (2008) and HMP (2004)
• General biological survey and vegetation mapping
• Analysis of potential project impacts on biological resources
• Analysis of project conformance with local, state, and federal biological regulations
Rocks Biological Consulting (RBC) began preparations for surveys by creating field maps using
Geographic Information System (GIS) and incorporating relevant data including a color aerial
photograph and the California Department of Fish and Wildlife's (CDFW) California Natural
Diversity Database (CNDDB) information for the U.S. Geological Society 7.5' San Luis Rey
Quadrangle. The CNDDB information was used to assess the potential for sensitive species to
occur within or immediately adjacent the project site.
On September 10, 2014 RBC mapped vegetation communities/land uses within the project site
to provide a baseline of the biological resources that occur or have the potential to occur.
Vegetation mapping was conducted by walking the project site and classifying habitats based on
the dominant and characteristic plant species in accordance with Holland's Preliminary
Descriptions of the Terrestrial Natural Communities of California (Holland 1986), as modified by
Oberbauer in Draft Vegetation Communities of San Diego County (Oberbauer et al. 2008). The
vegetation and land uses were mapped on an aerial photograph at 1 :2400 scale (1 inch= 200

feet). The extent of each habitat type (delineated as a habitat polygon on the compiled vegetation
map) was calculated using GIS. Representative photographs of the project site were taken and
are included as Appendix A.
General biological surveys and/or habitat assessments for plants and animals were conducted
during the vegetation mapping effort and included a reconnaissance survey for off-site wetlands,
riparian habitat, oak woodland, nesting raptors, and/or narrow endemic species located within
100-feet of the property. Plant species observed during the field survey were identified and
recorded in field notebooks. Plant names follow the Checklist of the Vascular Plants of San Diego
County, 5th edition (Rebman and Simpson 2014); a list of the vascular plant species observed
within the project site is presented in Appendix B.
Wildlife species were detected during the field survey by sight, calls, tracks, scat, or other signs,
and were recorded in field notebooks. Binoculars (8X42 magnification) were used to aid in the
identification of wildlife. In addition to species observed during the surveys, expected wildlife use
of the BSA was determined by known habitat preferences of local species and knowledge of their
biogeographic distribution in the region. Scientific and common names of animals follow
American Ornithologists' Union (AOU 2014) for birds, Wilson and Reeder (2005) for mammals,
and Crothers (2014) for reptiles and amphibians. A list of wildlife species observed within or
adjacent the project site is presented in Appendix B.
The project site was also assessed for the presence of potential wetlands and/or jurisdictional
streambeds, but no formal jurisdictional delineation per U.S. Army Corps of Engineers was
conducted.
The field survey was conducted under clear skies, calm winds, and warm weather (77 °F). Due to
the late season timing of the survey, faunal activity at the time was low and early spring annual
plant species were not observable. However, summer flowering species and evergreen perennial
species were documented. No focused surveys for rare, threatened, or endangered plant or
wildlife species were conducted.
4 RESULTS
4.1 Physical Setting
The approximately 3.79-acre project site is located on moderately sloping to flat ground near the
terminus of Afton Way. The site consists primarily of residential development and associated
ornamental plantings, including large patches of eucalyptus woodland. The surrounding land use
is dense residential housing with associated local roads.
4.2 Vegetation Communities and Land Uses
A total of five vegetation communities or land uses were identified within the project site as shown
in Table 1. The spatial distribution of each vegetation community and land use is presented on
the Biological Resources Map (Figure 3).

Urban/Developed 0.22
Total 3.79
Diegan Coastal Sage Scrub -Disturbed
Diegan coastal sage scrub is comprised of low growing, aromatic, drought deciduous, soft-
woody shrubs to about four feet high, many of which are facultatively drought-deciduous. The
Diegan subtype of coastal sage scrub consists of California sagebrush (Artemisia californica),
California buckwheat (Eriogonum fasciculatum), laurel sumac (Malosma laurina), lemonadeberry
(Rhus integrifolia), and black and white sage (Salvia mellifera and S. apiana). This collection of
species is typically found on dry, south-facing slopes or clay-rich soils that are slow to release
stored water.
Within the project site, the Diegan coastal sage scrub has been degraded by previous clearing or
ground disturbance likely associated with the previous residential use of the property. The small
patch still present is located near the northern boundary of the site and consists of an over story
of eucalyptus woodland in most areas further reducing its habitat value. The Diegan coastal sage
scrub -disturbed onsite is not suitable for the federally-listed threatened coastal California
gnatcatcher (Polioptila californica californica) because of its small size, highly degraded condition,
and isolation from other patches of suitable Diegan coastal sage scrub offsite.
Eucalyptus Woodland
Eucalyptus woodland is typically characterized by dense stands of gum trees (Eucalyptus spp.)
that are native to Australia. Eucalyptus trees were originally planted in groves throughout many
regions of coastal California as a source of lumber, as windbreaks, and as a horticultural novelty.
Eucalyptus trees have increased their cover through natural regeneration, particularly in moist
areas sheltered from strong coastal winds.
Within the project site, eucalyptus trees occur primarily in dense groves with a barren understory
or sparse non-native grassland. Although a non-native species, eucalyptus trees provide some
wildlife habitat value as they have the potential to support nesting birds including raptor species
because of their height and dense canopy.
Non-Native Grassland
Non-native grassland consists of a dense to sparse cover of annual grasses, often with native and
non-native annual forbs (Holland 1986). This habitat generally occurs on fine-textured loam or
clay soils that are moist to waterlogged during the winter rainy season, and very dry during the
summer and fall. This habitat is a disturbance-related community most often found in old fields or
ROCKS BIOLOGICAL CONSUL TING 6
C """"'' """" 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT
openings within native scrub habitats. This association has replaced native grassland and coastal
sage scrub at many localities throughout southern California.
The non-native grassland within the project site is comprised primarily of ripgut brome (Bromus
diandrus), slender wild oat (Avena barbata), and purple false-brome (Brachypodium distachyon).
Some broad-leaved forbs such as Russian thistle (Sa/so/a tragus), and short-pod mustard
(Hirschfeldia incana) are also present.
Ornamental
Ornamental vegetation typically consists of non-native landscape and/or garden species that are
planted in association with buildings, roads, and developments or have escaped cultivation and
occur within native habitats. San Diego County supports a wide variety of ornamental trees and
shrubs, as well as herbs that decorate urban areas.
Ornamental vegetation within the project site is primarily associated with the house and adjacent
yard. Species present include Cape leadwort (Plumbago auriculata), Italian stone pine (Pinus
pinea), mousehole tree (Myoporum /aetum), golden wattle (Acacia longifolia), eucalyptus, hottentot
fig (Carpobrotus edu/is), and desert carpet (Acacia redo/ens).
Urban/Developed
Urban/developed areas within the project site support no native vegetation and are comprised of
human-made structures such as buildings and roads. The level of soil disturbance is so high that
only ruderal plant species can persist. The developed areas onsite include the existing house,
outbuildings, and paved driveway and Afton Way.
4.3 Flora
The project site supports a low diversity of vegetation types and plant species due to the
developed and disturbed nature of the site. In addition, observations of annual plant species were
likely low due to the late season timing of the field survey. Most of the floral diversity onsite is due
to the large number of ornamental plantings associated with the residential landscaping. No
sensitive plant species, including City narrow endemic species, were observed or have the
potential to occur onsite. A list of plant species observed during the field survey is included as
Appendix B.
4. 4 Wildlife
The project site supports a low diversity of wildlife due to the urban setting of the site, the
developed and degraded nature of the vegetation communities, and isolation from large
vegetated open space areas. In addition, observations of wildlife species were likely low due to
the late season timing of the field survey. Also, a nighttime survey was not conducted so
nocturnal animals were not documented. No sensitive wildlife species, including City Narrow
Endemic Species, were observed or have the potential to occur onsite. A list of wildlife species
observed during the field survey is included as Appendix B.
4.5 Sensitive Species and Habitats
Sensitive biological resources are those defined as follows: 1) Species that have been given
special recognition by federal, state, or local conservation agencies and organizations due to
ROCKS BIOLOGICAL CONSUL TING 7
.....,,
2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT
limited, declining, or threatened/endangered population sizes; 2) Species and habitat types
recognized by local and regional resource agencies as sensitive; 3) Habitat areas or vegetation
communities that are unique, are of relatively limited distribution, or are of particular value to
wildlife; 4) Wildlife corridors and habitat linkages; and/or 5) Biological resources that may or may
not be considered sensitive, but are regulated under local, state, and/or federal laws.
For the purposes of this report, species are considered to be sensitive if they meet one or more of
the following criteria:
• Listed under the federal or state Endangered Species Act (CDFW 2014; USFWS 2014).
• City of Carlsbad HMP Covered Species (2004)
• USFWS Birds of Conservation Concern (USFWS 2014)
• CDFW Special Animals List (CDFW 2011)
• CDFW Species of Special Concern (CDFW 2014).
• CDFW Fully Protected Species (CDFW 2014).
• Covered as a state protected furbearing mammal (California Code of Regulations [14
CCR Section 460]).
• Listed as having a California Rare Plant Rank (CRPR; formerly CNPS List, CNPS 2014).
No sensitive plant or animal species were observed and none are expected due to the developed
and disturbed nature of the project site.
4.6 Jurisdictional Wetlands
The project site does not support jurisdictional wetlands or other Waters of the U.S. or state such
as intermittent or ephemeral streambeds. A concrete-lined brow ditch is present along the
northern and eastern boundaries of the site. These features are not jurisdictional because they
were constructed in upland areas for the purpose of conveying storm water runoff and do not
represent or replace a naturally occurring streambed or other wetland area.
4.7 Wildlife Movement Corridors
A wildlife corridor can be defined as a link of wildlife habitat, usually consisting of native vegetation
that joins two or more larger areas of similar wildlife habitat. Corridors are critical for the
maintenance of ecological processes including allowing for the movement of animals and the
continuation of viable populations. Corridors enable migration, colonization and interbreeding of
plants and animals. Corridors can consist of large, linear stretches of connected habitat (such as
riparian vegetation) or as a sequence of stepping-stones across the landscape (discontinuous
areas of habitat such as wetlands and ornamental vegetation), or corridors can be larger habitat
areas with known or likely importance to local fauna.
Regional corridors are defined as those linking two or more large patches of habitat, and local
corridors are defined as those allowing resident animals to access critical resources (food, cover,
and water) in a smaller area that might otherwise be isolated by urban development.
The project site does not function as a wildlife corridor because it is surrounded on all sides by
dense residential development. The nearest sizable open space habitats are associated with
ROCKS BIOLOGICAL CONSUL TING 8
""""' 2200 AFTON WAY PROJECT BIOLOGICAL ~OURCES TECHNICAL REPORT
Buena Vista Creek and Lagoon to the north and west that are approximately 0.6 to 1 mile from
the project site. There is no continuous connection or corridor between the project site and these
open space areas. The project site is not included as a Core or Linkage area under the City's
HMP.
5 PROJECT IMPACTS
This section describes the proposed project's potential direct, indirect, and/or cumulative impacts
on sensitive biological resources that could occur with implementation of the proposed project.
The following thresholds of significance have been used to determine whether project
implementation would result in a significant direct, indirect, and/or cumulative impact. These
thresholds are based on Appendix G of the state CEQA Guidelines (CCR Title 14, Division 6,
Chapter 3, Sections 15000-15387). A significant biological resources impact would occur if the
project would:
• Have a substantial adverse effect, either directly or through habitat modifications, on any
species identified as a candidate, sensitive, or special status species in local or regional
plans, policies, or regulations, or by CDFW or USFWS;
• Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, or regulations or by CDFW or
USFWS;
• Have a substantial adverse effect on federal protected wetlands as defined by Section 404
of the Clean Water Act (CWA) (including, but not limited to, marshes, vernal pools, and
coastal areas) or any state-protected jurisdictional areas not subject to regulation under
Section 404 of the CWA through direct removal, filling, hydrological interruption, or other
means;
• Interfere substantially with the movement of any native resident or migratory fish or wildlife
species or with established native resident or migratory wildlife corridors, or impede the
use of native wildlife nursery sites;
• Conflict with any local policies or ordinances protecting biological resources, such as a
tree preservation policy, or ordinance;
• Conflict with the provisions of an adopted habitat conservation plan; natural community
conservation plan; or other approved local, regional, or state habitat conservation plan; or
• Substantially reduce the habitat of a fish or wildlife species; cause a fish or wildlife
population to drop below self-sustaining levels; threaten to eliminate a plant or animal
community; or substantially reduce the number or restrict the range of an endangered,
rare, or threatened species.
5.1 Direct impacts
Direct impacts include actions that result in removal or disturbance of sensitive habitat; incidental
take of sensitive species; and degradation of habitats due to construction-related activities. Direct
project impacts were quantified by overlaying the project plan or 'footprint' on the Biological
ROCKS BIOLOGICAL CONSUL TING 9
,-., '-:) 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT
Resources Map (Figure 3). Direct impacts on habitats or land uses are listed in Table 2 and
shown on Figure 3.
Table 2. Proposed Project Impacts on Vegetation Communities and Land Uses
Existing Proposed
Vegetation Community Acreage Impact Acreage
Diegan coastal sage scrub -disturbed 0.18 0.18
Non-native grassland 1.27 1.20
Ornamental 1.22 1.03
Eucalyptus Woodland 0.91 0.88
Urban/Developed 0.22 0.22
Total 3.79 3.50
Permanent direct impacts on Diegan coastal sage scrub, non-native grassland, and eucalyptus
woodland are considered potentially significant under the City's Guidelines for Biological Studies
and HMP and would require mitigation to offset the impact. Impacts on ornamental and
urban/developed areas onsite are not considered significant and would not require mitigation.
Habitats within the project site have the potential to support nests that would be protected under
the Migratory Bird Treaty Act and/or the California Fish and Game Code (§3503) under which it is
unlawful to "take, possess, or needlessly destroy" avian nests or eggs. Thus potential direct
impacts could occur if vegetation clearing is undertaken during the breeding season (February 15
-September 15).
There would be no significant impacts on sensitive species including HMP Covered Species as
none are present onsite. There would be no significant impacts on wildlife movement as the
project site does not serve as a local or regional wildlife corridor.
5.2 Indirect impacts
Indirect impacts include short-term impacts that may occur during construction, such as
sediment or other discharges that could impact water quality; noise impacts; lighting impacts;
increase in human activity during construction; and project operations.
The project would entail demolition of existing structures, earthwork, and single-family home
construction activities with the potential to generate dust and noise. Ground disturbance during
construction also has the potential to result in accelerated erosion. However, the project will
incorporate measures to address and reduce these types of impacts, including implementation of
standard dust control measures and compliance with City residential noise regulations. With
these in place, and given the temporary nature of dust and noise-generating activities,
construction dust and noise are not anticipated to result in significant impacts on biological
resources. In addition, the project will require a Stormwater Pollution Prevention Plan (SWPPP),
which will include measures to control erosion during and following construction. With the
SWPPP in place, significant impacts associated with accelerated erosion of disturbed ground are
not expected.
ROCKS BIOLOGICAL CONSUL TING 10

~ 2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT
5.3 Cumulative impacts
Cumulative impacts include both the potential regional (long-term, additive) effects of a project
and the ways a project, in combination with other projects and conditions in a region, may affect
an ecosystem or one of its components beyond the project limits and on a regional scale.
Because the project would be consistent with the City of Carlsbad's HMP, a regional conservation
plan, there would be no cumulatively significant biological impacts.
6 MITIGATION MEASURES
This section describes the mitigation measures that, if implemented, would reduce the proposed
project's potential direct, indirect, and/or cumulative impacts on sensitive biological resources to
below the level of significant.
6.1 Habitat Mitigation
Under the City's Guidelines for Biological Studies (2008), project impacts on sensitive HMP habitats must
be mitigated. Project mitigation must occur at ratios outlined in Table 3, which also itemizes the proposed
impacts on each habitat type and the resulting mitigation requirement.
Pursuant to City regulations, mitigation for impacts on HMP habitats may be achieved by conserving lands
on or off-site, or through payment of in lieu fees to the City's HMP. As shown in Table 3, the City currently
charges a per acre fee based on the habitat group and type. Project impacts on Diegan coastal sage scrub
-disturbed, non-native grassland, and eucalyptus woodland can be mitigated by payment of the in-lieu fee.
Lands designated as urban/developed and ornamental are not considered to have significant habitat value
and would not require mitigation. With the payment of in lieu fees the project will provide adequate
mitigation for impacted habitats.

Urban/Developed 0.22 ----
Total 3.50 --$17,395.92
Note: Mitigation ratios and fees per City of Carlsbad's development fee schedule (September 1, 2014)
6.2 Nesting Bird Mitigation
Within the City's HMP area, clearing and grubbing activities are generally prohibited during the
bird breeding season (February 15 -September 15) to avoid direct impacts on raptors and/or
native/migratory birds. If construction activities cannot be avoided during the breeding season, a
ROCKS BIOLOGICAL CONSUL TING 11
~· "'""\
'-"' -.,I
2200 AFTON WAY PROJECT BIOLOGICAL RESOURCES TECHNICAL REPORT
qualified biologist shall conduct a pre-construction (precon) survey to determine the presence or
absence of nesting birds within the proposed impact area and an additional 500-foot survey
buffer within three days of construction (including removal of vegetation).
If nests of listed birds, migratory birds, raptors, or other sensitive species are located they will be
fenced with a buffer of at least 500 feet of active nests of listed species and 300 feet from other
sensitive bird species. All construction activity will be prohibited within this area. If nesting birds
are not observed during the precon survey, no further mitigation is required.
7 DISCUSSION
The project site is not within or adjacent to an existing or proposed hardline or standards area as
defined in the City's HMP and is not within the Coastal Zone. The project site does not support
state and/or federally listed plants, animals, or jurisdictional wetlands or other Waters of the U.S.
or state. The site does not support City Narrow Endemic or Covered Species.
The proposed project could result in a significant impact on habitats including Diegan coastal
sage scrub, non-native grassland, and eucalyptus woodland and on nesting birds. However,
through incorporation of the mitigation measures outlined in Section 5, impacts would be reduced
to below a level of significance.
In addition to the mitigation requirements listed above, the project will require a Carlsbad HMP
Permit and must comply with the Standard Impact Mitigation Measures listed in Appendix A in the
City's Guidelines for Biological Studies. These guidelines provide project design, pre-
construction, and construction related mitigation measures that should be addressed before and
during project implementation.
