SUMMARY OF FINDINGS
The Ocean Street project consists of the development of approximately three acres just north of
Mountain View Drive, west of the Southern Pacific railroad, and south of the Buena Vista
Lagoon in the City of Carlsbad, California. The project proposes to construct a multi-family
residential complex with associated infrastructure including parking facilities, landscaping, and a
swimming pool. Existing apartment facilities are currently present on the property and will be
removed as part of the proposed project. The local fire department reviewed the proposed
project to ensure compliance with existing policies and regulations, including proper fire
management, and it was determined that a fuel suppression/modification zone was not needed
due to the site's location within a high-density residential neighborhood and the lack of fuel in
both onsite and offsite areas.
On September 1, 2005, Dudek & Associates, Inc. (Dudek) biologists Tricia L. Wotipka and
Jeffrey D. Priest conducted a general biological survey of the three-acre property, which
included a general wildlife and botanical survey, vegetation community mapping, a sensitive
habitat assessment, and the preparation of a biological resources map. On November 8, 2005,
Dudek biologist Tricia L. Wotipka conducted a wetlands delineation of offsite areas to determine
the location of jurisdictional waters of the U.S., including wetlands, in relation to the project site.
Developed land was the only land cover type present within the project site and included an
existing multi-family apartment complex with associated infrastructure, including covered
parking structures and ornamental landscaping. No jurisdictional resources (i.e., wetlands and
non-wetland waters of the U.S.) were identified onsite.
No sensitive plant or wildlife species were detected onsite during the site visit and due to the
extent of development present onsite none are expected to occur. The lower basin of the Buena
Vista lagoon is located offsite and approximately 120 feet north of the project site. Due to the
high quality biological resources present there, the lagoon likely supports a variety of waterfowl,
fish, amphibian, and coastal avifauna) species.
The site supports a diverse assemblage of ornamental trees and shrubs, which could serve as
potential nesting habitat for resident songbirds. Breeding birds may be significantly impacted by
proposed tree/shrub removal and construction-related noise, which can result in the disruption of
foraging, nesting, and reproductive activities. If tree removal occurs during the migratory bird
nesting season (typically February through August), a focused avian nesting survey shall be
performed by a qualified wildlife biologist 72 hours prior to onsite tree removal in accordance
with the Migratory Bird Treaty Act (16 U.S.G. 703-712). Construction should not commence

until a qualified wildlife biologist has inspected all of the trees onsite for nesting birds. If any
active nests are detected, the area will be flagged, along with a buffer of 25 to 300 feet (specific
width to be determined by the project biologist) and will be avoided until the nesting cycle is

INTRODUCTION
The Ocean Street project consists of the development of approximately three acres just north of
Mountain View Drive, west of the Southern Pacific railroad, and south of the Buena Vista
Lagoon in the City of Carlsbad, California. The project proposes to construct a multi-family
residential complex with associated infrastructure including parking facilities, landscaping, and a
swimming pool. Existing apartment facilities are currently present on the property and will be
removed as part of the proposed project. The local fire department reviewed the proposed
project to ensure compliance with existing policies and regulations, including proper fire
management, and it was determined that a fuel suppression/modification zone was not needed
due to the site's location within a high-density residential neighborhood and the lack of fuel in
both onsite and offsite areas.
On September 1, 2005, Dudek & Associates, Inc. (Dudek) biologists Tricia L. Wotipka and
Jeffrey D. Priest conducted a general biological survey of the three-acre property, which
included a general wildlife and botanical survey, vegetation community mapping, a sensitive
habitat assessment, and the preparation of a biological resources map. On November 8, 2005,
Dudek biologist Tricia L. Wotipka conducted a wetlands delineation of offsite areas to determine
the location of jurisdictional waters of the U.S., including wetlands, in relation to the project site.
The purpose of the biological resource technical report is to map and assess the existing
vegetation and survey for plant and animal species recognized as sensitive by local, state, or
federal wildlife agencies and environmental organizations. Foil owing the surveys, direct,
indirect and cumulative impacts to vegetation communities and species were evaluated based on
the proposed project. This report describes the biological character of the project study area;
provides an analysis of direct, indirect and cumulative impacts based on the proposed project
scenario; analyzes the biological significance of the site with respect to regional biological
resource planning; and discusses mitigation measures which will reduce significant impacts to a
level below significant.
2.0 METHODS AND SURVEY LIMITATIONS
Data regarding biological resources present on the project site were obtained through a review of
pertinent literature and through field reconnaissance; both are described in detail below.

2.1 Literature Review
Sensitive biological resources present or potentially present onsite were identified through a
literature search using the following sources: U.S. Fish and Wildlife Service (USFWS) (2000),
California Department of Fish and Game (CDFG) (2005b-e), and California Native Plant
Society's (CNPS) Inventory of Rare and Endangered Plants of California (CNPS website, June
2005). The California Natural Diversity Database (CNDDB) (CDFG 2005a) was also reviewed
to identify sensitive species possibly occurring within the project limits. General information
regarding wildlife species present in the region was obtained from Unitt (1984) for birds, Bond
(1977) for mammals, Stebbins (2004) for reptiles and amphibians, and Emmel and Emmel
(1973) for butterflies. The Soil Survey, San Diego Area, California Part 1 (Bowman 1973) also
was reviewed to identify potentially-occurring sensitive plants based upon known soil
associations. General information regarding vegetation communities and plant species was
obtained from Holland (1986) and Hickman (1993).
In terms of regional preserve planning efforts, the proposed project is located in the Multiple
Habitat Conservation Plan (MHCP) study area as part of the City of Carlsbad (City) approved
Habitat Management Plan (HMP) area (City of Carlsbad 2004). Therefore, the City's final draft
of the HMP was consulted to ensure consistency with local conservation efforts.
2.2 Field Reconnaissance
Dudek biologists Jeffrey D. Priest and Tricia L. Wotipka conducted vegetation communities
mapping, a general botanical inventory, and a general wildlife inventory according to the
schedule in Table 1.

using ArcGIS and a Geographic Information System (GIS) coverage was created. Once in
Arc GIS, the acreage of each land cover type present onsite was determined.
Vegetation community classifications used in this report follow Holland (1986), with
modifications to accommodate the lack of conformity of the observed communities to those of
Holland.
2.2.2 Flora
All plant species encountered during the field surveys were identified and recorded. Those
species that could not be identified immediately were brought into the laboratory for further
investigation. Latin and common names of plants follow The Jepson Manual (Hickman, 1993)
or more recent published taxonomical revisions of genera. Where not listed in Hickman (1993),
common names are taken from Simpson and Rebman (2002). A list of plant species observed on
the property is presented in Appendix A.
2.2.3 Fauna
Wildlife species detected during the field surveys by sight, calls, tracks, scat, or other signs were
recorded. Binoculars (7x50 power) were used to aid in the identification of observed wildlife. In
addition to species actually detected, expected wildlife use of the site was determined by known
habitat preferences of local species and knowledge of their relative distributions in the area. A
list of wildlife species observed on the property is presented in Appendix B.
Latin and common names of animals follow Stebbins (2003) for reptiles and amphibians,
American Ornithologists' Union (2003) for birds, Jones et a!. (1997) for mammals, and Emmel
and Emmel (1973) for butterflies.
2.2.4 Jurisdictional Wetlands Delineation
On November 8, 2005, Dudek biologist Tricia L. Wotipka conducted a formal delineation of
"waters of the U.S.", including wetlands, under the jurisdiction of the U.S. Army Corps of
Engineers (ACOE), pursuant to Section 404 of the federal Clean Water Act; the Regional Water
Quality Control Board (RWQCB), pursuant to Section 401 of the federal Clean Water Act; the
CDFG, pursuant to Section 1602 of the California Fish and Game Code; and the jurisdiction of
the California Coastal Commission (CCC) pursuant to the Coastal Act of 1976. Wetlands were
delineated in accordance with the 1987 US. Army Corps of Engineers Wetlands Delineation
Manual (Technical Report Y-87-1). Special attention was paid to the offsite Buena Vista
Lagoon, located approximately 120 feet northwest of the site. The boundaries of the

jurisdictional resources were delineated using a Global Positioning System (GPS) backpack unit
with sub-meter accuracy. Jurisdictional resources were mapped directly onto a I"= I 00' scale
aerial photograph (Air Photo USA, January 2005). Vegetation, hydrology and soils were
examined at each of the potential wetland sites. The U.S. Fish and Wildlife Service National List
of Plant Species that Occur in Wetlands: California (Region 0) was used to determine the
indicator status of plant species. The channel banks of the lagoon were examined for evidence of
an ordinary high water mark (OHWM), including sediment deposition and water marks. Drift
Jines were noted, where present. Munsell soil color charts were used to determine soil chroma
and value. Two soil pits were prepared along the lagoon boundary to determine the extent of
ACOE-, CCC-and RWQCB-jurisdictional areas at this location. The soil pits were each dug to a
depth of approximately eight inches. Excavated soils were examined for evidence of hydric
conditions, including low chroma values and mottling, vertical streaking and high organic matter
content in the upper horizon. Data forms for each data station are attached to this document
(Appendix C).
Following completion of the wetlands delineation, all vegetation polygons were transferred to a
topographic base and digitized using ArcGIS and a GIS coverage was created. Once in ArcGIS,
the extent of wetland communities in proximity to the site was determined.
2.2.5 Sensitive/Regulated Biological Resources
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
limited, declining, or threatened 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; and (4)
wildlife corridors and habitat linkages. Regulated biological resources may or may not be
considered sensitive, but are regulated under local, state, and/or federal laws.
Notes gathered from the field concerning biotic components were compared with lists of
sensitive plants and animals from the CDFG, USFWS, and CNPS. Appendix D contains a
discussion of the various degrees of sensitivity recognized by each of these organizations.
2.3 Survey Limitations
Survey limitations include seasonal constraints, a diurnal bias and the absence of focused
trapping for mammals and reptiles. As shown in Table 1, the site visit was conducted in late
summer/early fall which would not allow for the detection of sensitive spring annual species.

However, due to the extent of disturbance onsite and in areas immediately offsite and adjacent to
the property, the potential for sensitive species to occur is low. Therefore, it was concluded that
a spring rare plant survey was not necessary.
Climatic conditions during the surveys were favorable for the identification of flora and fauna.
Surveys were conducted during the daytime to maximize visibility for the detection of plants and
most animals. Birds represent the largest component of the vertebrate fauna, and because most
are active in the daytime, diurnal surveys maximize the number of observations of this portion of
the fauna. In contrast, daytime surveys usually result in few observations of mammals, many of
which may be active at night. In addition, many species of reptiles and amphibians are nocturnal
or cryptic in their habits and are difficult to observe using standard meandering transects.
3.0 PHYSICAL CHARACTERISTICS
3.1 Site Description
The property is located just north of Mountain View Drive and the Carlsbad Army and Navy
Academy, west of the Southern Pacific railroad, and south of the Buena Vista Lagoon in the City
of Carlsbad, California (Figure 1). The property is situated on the U.S. Geological Survey
(USGS) 7.5 minute San Luis Rey quadrangle in Section I; Township 12 South; Range 5 West;
latitude 33° 09' SS''N and longitude 117° 21' 25"W (Figure 2).
3.1.1 Topography
The project site is not topographically diverse, with relatively flat lowland areas comprising most
of the site. Topographic relief ranges from approximately 10 feet above mean sea level (AMSL)
to approximately 40 feet AMSL. The property currently supports an existing, gated multi-family
apartment complex with associated infrastructure including covered parking structures and
ornamental landscaping. Two concrete staircases on the east and west ends of the complex lead
residences from the building complex down to a flat terrace that most likely supported picnic
tables and other recreational uses. The site is bound by residential development and the Pacific
Ocean to the west, residential development and the Carlsbad Army and Navy Academy to the
south, the Southern Pacific Railroad and State Highway I 0 I to the east, and the lower basin of
the Buena Vista Lagoon to the north and east.

3.1.2 Soils
Biological Resources Technical Report
Ocean Street Property
The project site supports one distinct soil type, Marina loamy coarse sand, two to nine percent
slopes (MlC). According to Bowman (1973), soils in the Marina series form on old beach ridges
and are comprised of very deep, loamy coarse sands derived from weakly consolidated to
noncoherent ferruginous eolian sand. This soil type is known to support sensitive plant taxa
within the MHCP.
4.0 RESULTS OF SURVEY
4.1 Botany -Plant Communities and Floral Diversity
Results of the biological survey indicate that one land cover type, developed land, occurs onsite.
A description of this land cover is provided below and the spatial distribution is shown in Figure
3.
4.1.1 Developed Land (3.00 acres)
Developed land typically refers to areas supporting man-made structures including homes, yards,
roadways, ornamentally-landscaped areas, and other highly modified lands supporting structures
associated with dwellings or other permanent structures. Such structures typically support little
to no natural vegetation growth and are not considered sensitive by local, state, or federal
agencies.
Onsite, developed land encompasses the entire 3.00-acre site and refers to an existing multi-
family residential complex with attendant features including covered parking structures, paved
walkways and parking lots, and ornamental landscaping associated with the complex (Figure 3).
Some scattered patches of non-native grasses and herbs occur along an existing fence line to the
north including hottentot fig ( Carpobrotus edulis ), Bermuda grass ( Cynodon dactyl on), ripgut
brome (Bromus diandrus), soft chess (Bromus hordeaceus), and slender wild oat (Avena
barbata). However, due to the small patch size and predominance of ornamental species these
areas were not mapped out separately.
4.1.2 Jurisdictional Waters ofthe U.S., Including Wetlands
No jurisdictional waters of the U.S., including wetlands, were identified onsite. The lower basin
of the Buena Vista lagoon is located approximately 120 feet north and offsite of the project site
(Figure 3).

Biological Resources Technical Report
Ocean Street Property
Floral Diversity
A total of 19 species of vascular plants, including four native (21 percent) and 15 non-native (79
percent) species, were recorded from the site. The recorded flora of the site and the proportion
of native species are limited as a consequence of the lack of native plant communities onsite.
The complete list of plant species identified onsite is provided as Appendix A.
4.2 Zoology-Wildlife Diversity
A total of 17 species of wildlife were observed onsite and in offsite areas during the site visit
(Appendix B). The largest concentration of wildlife species was noted near the lower basin of the
Buena Vista Lagoon. Due to the extent of developed land onsite, the project site itself provides
little to no habitat value for local wildlife species. Wildlife species observed offsite are noted as
such in Appendix B in order to accurately characterize the existing conditions.
4.2.1 Birds
Fifteen species of birds were observed during the survey. No state-or federally-listed threatened
or endangered bird species were observed onsite and due to the lack of quality habitat onsite,
none are expected to occur there.
Common species observed onsite include Anna's hummingbird (Calypte anna), mourning dove
(Zenaida macroura), common raven (Corvus corax), American crow (Corvus brachyrhynchos)
black phoebe (Sayornis nigricans), and European starling (Sturnus vulgaris).
4.2.2 Reptiles and Amphibians
No reptile species were observed onsite.
4.2.3 Mammals
Two species of mammals were detected onsite: Botta's pocket gopher (Thomomys bottae) and
California ground squirrel (Spermopholis beecheyi).
4.2.4 Invertebrates
No invertebrates were observed onsite.

4.3 Sens itive Biological Resources
The following resources are discussed in this section: (1) plant and animal species present in the
project vicinity that are given special recognition by federal, state, or local conservation agencies
and organizations owing to declining, limited, or threatened populations, that are the result, in
most cases, of habitat reduction; and (2) habitat areas that are unique, are of relatively limited
distribution, or are of particular value to wildlife.
4.3.1 Sensitive Plant Species
No state-or federally-listed endangered or threatened species or species considered sensitive by
the CNPS were observed onsite and due to the extent of developed land present, none are
expected to occur.
Table 2 lists several sensitive plant species that have a potential to occur onsite based on the
location of the site and general soils mapping. For each species listed, a determination is made
regarding the potential for the species to occur onsite, based on the location of the site, habitats
present, degree of disturbance to the vegetation on the site, and extent of surveys already
conducted.

Sensitive Habitats/Regulated Resources
Sensitive habitats are those that are considered to support unique vegetation commurut1es,
sensitive plant and wildlife species, or function as corridors for wildlife movement. Unique
vegetation communities include habitats found only in the San Diego region, a local
representative of species not generally found in San Diego County, or are outstanding examples
of CDFG sensitive plant communities. Regulated biological resources may or may not be
considered sensitive, but are regulated under local, state, and/or federal laws.
Developed land is not a sensitive and/or regulated resource by local, state, and federal agencies. I Therefore, no sensitive resources are present onsite.

4.3.4 Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide
avenues for the migration of animals. Wildlife corridors contribute to population viability by
assuring continual exchange of genes between populations, providing access to adjacent habitat
areas for foraging and mating, and providing routes for recolonization of habitat after local
extirpation or ecological catastrophes (e.g., fires).
Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse
effects of habitat fragmentation. Habitat linkages provide a potential route for gene flow and
long-term dispersal of plants and animals and may also serve as primary habitat for smaller
animals, such as reptiles and amphibians. Habitat linkages may be continuous habitat or discrete
habitat islands that function as stepping stones for dispersal.
Although the site is adjacent to habitat associated with the Buena Vista Lagoon, the site itself is
developed and disturbed, which precludes it from functioning as a wildlife corridor or habitat
linkage.
4.4 Regional Resource Planning Context
In San Diego County, several conservation planning efforts have been completed or are currently
in progress with the long-term goal of establishing a regional reserve system that will protect
native habitat lands and their associated biota. The ultimate goals of these plans are the
establishment of biological reserve areas in conformance with the State Natural Communities
Conservation Plan (NCCP) Act, and to contribute to the preserve system already established by
the approved Multiple Species Conservation Plan (MSCP) in southwestern San Diego County.

Pursuant to the NCCP Act, the City prepared a draft HMP and submitted it to the USFWS and
the CDFG in December 1999. In November 2004, the draft HMP was approved.
The City's HMP is designed to provide guidance for preserving habitat diversity and protecting
sensitive biological resources while still permitting development in accordance with the Carlsbad
General Plan and Growth Management Plan (City of Carlsbad 2004).
To help achieve this goal, certain areas, known as focused planning areas (FPAs), have been
designated as lands with high biological value that will be considered for conservation or
development. These areas include HMP Cores, Linkage Areas, and Special Resources, as
defined in the HMP. In terms of regional preserve planning efforts, the project site is located
within an urbanized region of the City of Carlsbad and is currently supporting high-density
residential development with ornamental landscaping.
However, the site is located just south of an existing hardline conservation area (see Figure 4)
and the Core 1 FP A, a core conservation area encompassing approximately 206 acres of land
comprised of mostly open water and riparian habitats associated with the Buena Vista Lagoon
(City of Carlsbad 2004). The Core 1 FPA links riparian habitats and associated upland habitats
to the Core 2 FPA, a 352-acre conservation area, via Buena Vista Creek. The project site is not
located within a FP A, special resource core area, existing hardline conservation area, proposed I hard line conservation area, or proposed standards area.

5.0 ANTICIPATED PROJECT IMPACTS
This section addresses direct, indirect, and cumulative impacts to biological resources resulting
from implementation of the proposed project.
Direct impacts were quantified by overlaying the proposed project design on the biological
resources map of the site. For the purposes of this assessment, all biological resources within the
limits of grading were considered directly impacted.
Indirect impacts result primarily from adverse "edge effects," and may be short-term in nature,
related to construction, or long-term in nature, associated with development in proximity to
biological resources within natural open space. For the proposed project, short-term indirect
impacts to adjacent communities may include dust and noise, which could temporarily disrupt
habitat and species vitality, and construction-related soil erosion and runoff.

Long-term indirect impacts may include noise, lighting, invasion by exotic plant and wildlife
species, effects of toxic chemicals (e.g., fertilizers, pesticides, herbicides, and other hazardous
materials), urban runoff from developed areas, soil erosion, litter, fire, and hydrological changes
(e.g., groundwater level and quality).
Cumulative impacts refer to incremental individual environmental effects of two or more
projects when considered together. These impacts taken individually may be minor, but
collectively significant as they occur over a period of time.
5.1 Direct Impacts
5.1.1 Vegetation Communities/Land Cover Types
As previously indicated, it is assumed that the entire site will be directly impacted. Therefore,
implementation of the proposed project would result in direct impacts to 3.00 acres of developed
land. Figure 3 illustrates the distribution of biological resources on the project site and the
locations where proposed impacts would occur.
5.1.2 Sensitive Plants
No sensitive plants were detected onsite during the general biological survey and due to the
extent of development and lack of suitable native habitats onsite, sensitive plant species are not
expected to occur. Therefore, implementation of the proposed project would not result in direct
impacts to sensitive plant species.
5.1.3 Sensitive Wildlife
No sensitive wildlife species were detected onsite during the general biological survey and due to
the extent of developed land and lack of native habitat, sensitive wildlife species are not expected
to occur. However, tall trees and shrubs present onsite may provide occasional perching and
nesting habitat for a variety of avian species. If construction commences during the bird nesting
season (i.e., February 15 through August 31 for most bird species; and January I through August
31 for raptors) potentially-breeding birds could be directly impacted by vegetation clearing
activities. Therefore, implementation of the proposed project may result in direct impacts to
nesting birds.

5.1.4 Habitat Linkages/Wildlife Corridors
The Buena Vista Lagoon, located approximately 120 feet north of the project site, is the only
biological resource in the project vicinity that serves as a wildlife movement corridor connecting
suitable wildlife habitat in the lower basin of the lagoon east toward Buena Vista Creek. The
project site itself is not located within a designated wildlife movement corridor and it is not
expected to aid in the movement of wildlife species due to the urbanization onsite and due to its
close proximity to other disturbed and developed sites. Thus, implementation of the proposed
project would not alter wildlife movement.
5.2 Indirect Impacts
Because the entire property would be impacted, potential indirect impacts would affect adjacent
lands. Adjacent offsite lands are comprised of existing residential development to the south,
east, and west, and disturbed lands to the north comprised of mostly non-native herbs and forbs
with scattered low-growing shrubs including notch-leaf marsh-rosemary (Limonium sinuatum)
and deerweed (Lotus scoparius). The Buena Vista Lagoon is located approximately 120 feet
offsite and to the north of the project and is not expected to be indirectly impacted by the project.
5.2.1 Vegetation Communities/Land Cover Types
Although short-term indirect impacts have the potential to occur, measures will be taken during
construction to minimize adverse edge effects including the implementation of best management
practices (BMPs) such as straw bales, silt fencing, and gravel bags. Also, all project grading will
be subject to the typical restrictions and requirements that address erosion and runoff, including
the federal Clean Water Act, National Pollution Discharge Elimination System (NPDES), and
the preparation of a Storm Water Pollution Prevention Plan (SWPPP). Noise impacts will be
temporary in nature and will be subject to the City's local ordinance regarding construction-
generated noise. Thus, no long-term indirect impacts to vegetation communities are anticipated.
5.2.2 Sensitive Plants
No sensitive plant species were found in the project site and are unlikely to be present
immediately offsite. Therefore, indirect impacts to sensitive plants are not expected to occur.

5.2.3 Sensitive Wildlife
Breeding birds using the ornamental trees and shrubs onsite can be significantly affected by
short-tenn construction-related noise, which can result in the disruption of foraging, nesting, and
reproductive activities.
Therefore, indirect impacts to nesting birds onsite due to construction-related noise may occur as
a result of the proposed project.
5.2.4 Habitat Linkages/Movement Corridors
Because the project site does not serve as a potential wildlife corridor and the lagoon is located
approximately 120 feet to the north, development of the property is unlikely to affect wildlife
movement. Thus, given the restrictions above, there are no indirect impacts associated with
project implementation.
5.2.5 Adjacent Offsite Lands
Because all project grading will be subject to the typical restrictions and requirements that
address erosion and runoff, including the federal Clean Water Act, NPDES, and the preparation
of a SWPPP, no indirect impacts to adjacent offsite lands are anticipated to occur.
5.3 Cumulative Impacts
Because no sensitive biological resources will be directly impacted by the proposed project,
implementation of the project in conjunction with other planned projects within the City of
Carlsbad would not result in cumulative impacts to biological resources.
6.0 ANALYSIS OF SIGNIFICANCE
6.1 Explanation of Findings of Significance
Impacts to sensitive habitats, sensitive plants, and sensitive wildlife species must be quantified
and analyzed to determine whether such impacts are significant under the California
Environmental Quality Act (CEQA). CEQA Guidelines section 15064(b) states that an ironclad
definition of "significant" effect is not possible because the significance of an activity may vary
with the setting. Appendix G of the Guidelines, however, does provide "examples of

consequences which may be deemed to be a significant effect on the environment" (Guidelines
section 15064[ e ]). These effects include substantial effects on rare or endangered species of
animal or plant or the habitat of the species. Guidelines section 1 5065(a) is also helpful in
defining whether a project may have "a significant effect on the environment." Under that
section, a proposed project may have a significant effect on the environment if the project has the
potential to: (1) substantially degrade the quality of the environment; (2) substantially reduce the
habitat of a fish or wildlife species; (3) cause a fish or wildlife population to drop below self-
sustaining levels; (4) threaten to eliminate a plant or animal community; (5) reduce the number
or restrict the range of a rare or endangered plant or animal; or (6) eliminate important examples
of the major period of California history or prehistory.
The evaluation of whether or not an impact to a particular biological resource is significant must
consider both the resource itself and the role of that resource in a regional context. Substantial
impacts are those that contribute to, or result in, permanent loss of an important resource, such as
a population of a rare plant or animal. Impacts may be important locally because they result in
an adverse alteration of existing site conditions, but considered not significant because they do
not contribute substantially to the permanent loss of that resource regionally. The severity of an
impact is the primary determinant of whether or not that impact can be mitigated to a level below
significant.
6.2 Vegetation Communities/Land Cover Types
6.2.1 Developed Land (3.00 acres)
Direct impacts to 3.00 acres of developed land is not considered significant because this land
cover has no biological resource value and it provides very limited to no habitat value for most
native species. Also, developed land is not considered sensitive by local, state, and federal
agencies and does not require mitigation under the City's approved HMP.
6.3 Sensitive Plants
As previously stated, no sensitive plant species will be impacted by the proposed project.
Therefore, potential impacts to sensitive plants are not significant.
6.4 Sensitive Wildlife
No sensitive wildlife species were detected onsite and none are expected to occur. Potential
impacts to sensitive wildlife are therefore not significant. However, if construction takes place

I
Biological Resources Technical Report
Ocean Street Property
during the bird-nesting season (i.e., January I through August 31), potential impacts to nesting
birds would be a significant but mitigable impact.
6.5 Habitat Linkages/Wildlife Corridors
Construction of the proposed development would not preclude the use of adjacent habitat by
wildlife or hinder its suitability as a wildlife corridor or habitat linkage. Therefore, there would
be no significant impacts to habitat linkages or wildlife corridors.
6.6 Adjacent Offsite Lands
Provided BMPs are incorporated into the project to avoid impacts to adjacent offsite properties
during construction, no significant direct or indirect impacts are anticipated to occur on adjacent
offsite lands. For a discussion of the City's HMP adjacency guidelines and standards in relation
to the proposed project please refer to Section 8. 0.
6.7 Relationship to Regional Resource Plan
The site currently supports existing residential uses and will continue to support residential uses
upon implementation of the proposed project. In addition, the project will recognize the
minimum required 100-foot buffer to protect offsite adjacent wetland preserve areas (i.e., the
Buena Vista Lagoon) from the proposed development, as mandated in the City's final HMP.
Therefore, development of the project site will not conflict with the goals, standards and policies
of the City's HMP and will proceed in accordance with the final HMP guidelines.
6.8 Cumulative Impacts
The proposed project will impact existing developed lands and will not result in the loss of
sensitive biological resources in the City of Carlsbad. Therefore, the proposed impacts are not
considered significant.

7.0 MITIGATION
7.1 Vegetation Communities/Land Cover Types
7.1.1 Developed Land Mitigation Requirements
The proposed project will impact 3.00 acres of developed land onsite. In accordance with the
City's HMP, mitigation is not required for impacts to this land cover type.
7.2 Sensitive Plants
No mitigation is proposed as impacts to sensitive plants are not expected to occur.
7.3 Sensitive Wildlife
To avoid impacts to nesting birds, construction should be timed, wherever feasible, to avoid the
bird nesting season (i.e., January I through August 31 for most species, including raptors).
However, if tree removal occurs during this time period, a focused avian nesting survey shall be
performed by a qualified wildlife biologist within 72 hours prior to tree removal in accordance
with the Migratory Bird Treaty Act (16 U.S.G. 703-712). Construction should not commence
until a qualified wildlife biologist has inspected all of the trees onsite for nesting birds. If any
active nests are detected, the area will be flagged, along with a buffer ranging from 25 to 300 feet
(specific width to be determined by the project biologist) and will be avoided until the nesting
cycle is complete.
7.4 Habitat Linkages/Wildlife Corridors
No mitigation is proposed for impacts to habitat linkages/wildlife corridors because the proposed
impacts are not considered significant.
8.0 HMP ADJACENCY STANDARDS
Although the proposed development is not immediately adjacent to the hard-lined conserved
habitat areas of the HMP, the adjacency standards and guidelines were reviewed with respect to
the proposed development. The HMP addresses the following topics: fire management, erosion
control, landscaping restrictions, fencing, signs, and lighting, and predator and exotic species
control (City of Carlsbad 2004).

Short-term indirect impacts to immediately adjacent lands may include dust, noise, and
construction-related soil erosion and drainage runoff. However, it is anticipated that all project
grading will be subjected to the typical restrictions and requirements that address these issues,
including the federal Clean Water Act, NPDES, and the preparation of a SWPPP. Noise impacts
will be temporary in nature and will be subject to the City's local ordinance regarding
construction-generated noise. In addition, no surface drainage from this project will be directed
to preserve areas. Therefore, the offsite preserve areas are not expected to be impacted by the
project.
Due to the project's location within an urban neighborhood and the lack of fuel resources offsite,
no fuel modification zones are proposed by the project. Because the proposed project is not
immediately adjacent to preserve areas, the use of non-native landscaping is not expected to
result in adverse effects to the offsite preserve areas. In addition, no fencing or signage is
proposed because the project is located at least 120 feet from any designated preserve area.
Lighting from the project will not be directed toward the preserve. Regarding predators and
exotic species control, the project site is currently fenced and will likely remain fenced as part of
the proposed project. In addition, the site is located approximately 120 feet south of the preserve.
Therefore, predators and exotic species issues are not expected to negatively affect the offsite
preserve.

Sensitive Species Categories
Taxa threatened throughout all or a significant portion of
their range.
Taxa likely to become endangered in the foreseeable future.
Taxa for which the USFWS currently has on file substantial
information on biological vulnerability and threat( s) to
support the appropriateness of proposing to list them as
endangered or threatened species.
Federal Species of Concern Taxa that were formerly Category 2 Candidates for listing
as threatened or endangered. This category is an
"unofficial" designation for species that may warrant
listing, but for which substantial information to support the
listing is lacking.
State of California
Endangered
Threatened
Rare
Taxa which are in serious danger of becoming extinct
throughout all, or a significant portion, of their range due to
one or more causes including loss of habitat, change in
habitat, over exploitation, predation, competition, or
disease (Section 2062 of the Fish and Game Code).
Taxa which, although not presently threatened with
extinction, are likely to become endangered species in the
foreseeable future (Section 2067 of the Fish and Game
Code).
Taxa which, although not presently threatened with
extinction, are present in such small numbers throughout
their range that they may become endangered if the present
environment worsens (Section 1901 of the Fish and Game
Code).

Lists
I A: Presumed Extinct in California
IB: Rare or Endangered in California and Elsewhere
2: Rare or Endangered in California, More Common Elsewhere
3: Need More Information
4: Plants of Limited Distribution
Note: Plants on CNPS list 1B meet California Department of Fish and Game Criteria for
Rare or Endangered listing.
R-E-D code
R (Rarity)
1-Rare, but found in sufficient numbers and distributed widely enough that the
potential for extinction or extirpation is low at this time.
2-Occurrence confined to several populations or to one extended population.
3-Occurrence limited to one or a few highly restricted populations, or present in such
small numbers that it is seldom reported.
E (Endangerment)
1-Not endangered
2-Endangered in a portion of its range
3-Endangered throughout its range
D (Distribution)
1-More or less widespread outside of California
2-Rare outside California
3-Endemic to California
