Subject: Biological Resources Letter Report for the De Anda Residence
Dear Ms. De Anda:
This report summarizes the results of the general biological and jurisdictional delineation surveys
conducted on the subject property and provides recommendations with respect to development
constraints and adherence to the City of Carlsbad's Habitat Management Plan (HMP), Carlsbad
Local Coastal Program (LCP), and other local, state, and federal^requirements pertaining to
biological resources.
PROPERTY LOCATION AND DESCRIPTION
The project site is generally located within the northwestern portion of San Diego County in the
City of Carlsbad (City), Califomia (Figure 1). More specifically, the project site is situated on
the western side of Jefferson Street, south of the intersection of Las Flores Drive, and is shown
on the U.S. Geological Survey 7.5-minute San Luis Rey quadrangle map in Section 36,
Township 11 South, and Range 5 West (Figures 2 and 3). The site consists of a single parcel
(Assessor's Parcel Number 155-140-41) encompassing approximately 0.38 acre.
Topography on site consists of a flat area adjacent to Jefferson Street and a steep west-facing
slope leading downhill to Buena Vista Lagoon. Elevations on site range from approximately 20
feet above mean sea level (amsl) along the western site boundary near Buena Vista Lagoon to
approximately 70 feet amsl along the eastern site boundary adjacent to Jefferson Street. The
majority of soils on site are mapped as terrace escarpments, with the extreme western edge
mapped as lagoon water (Bowman 1973). The site consists of vacant land primarily supporting
non-native vegetation communities.

Surrounding land uses consist of single- and multi-family residential development to the north
and south, and Jefferson Street immediately to the east. The eastern side of Jefferson Street has
additional single-family residential housing. The Buena Vista Lagoon lies to the west of the site.
The proposed project would develop a single-family residence on the eastern portion of the site
adjacent to Jefferson Street.
METHODS
Prior to conducting biological field surveys, searches of the Califomia Department of Fish and
Wildlife (CDFW) Califomia Natural Diversity Database (CNDDB) and U.S. Fish and Wildlife
Service (USFWS) sensitive species database were performed for information regarding sensitive
species known to occur within the vicinity of the site. Sensitive species are those that have been
given special recognition by federal, state, or local govemment agencies and organizations
because of limited, declining, or threatened populations. Focused surveys for rare plants and
listed or sensitive animal species were not conducted as part of this survey and report.
HELIX biologist Stacy Nigro conducted a general biological survey and jurisdictional
delineation of the site on June 20, 2013. Vegetation was mapped on a I'-TS' scale aerial
photograph. The site was surveyed on foot with the aid of binoculars. All plant and animal
species observed or otherwise detected during the survey were recorded in field notes and on the
aerial photograph (Appendices A and B). Animal identifications were made in the field by direct,
visual observation, or indirectly by detection of calls, burrows, tracks, or scat. All plant
identifications were made in the field or in the lab through comparison with voucher specimens
or photographs. However, the lists of species identified are not necessarily comprehensive
accounts of all species that occur on the site, as species that are nocturnal, secretive, or
seasonally restricted may not have been observed. No focused surveys for sensitive plant or
animal species have been conducted to date.
A jurisdictional delineation was conducted to identify and map potential jurisdictional waters and
wetlands, including waters of the U.S. subject to the regulatory jurisdiction of the U.S. Army
Corps of Engineers (USAGE) pursuant to Section 404 of the federal Clean Water Act (GWA);
streambed and riparian habitat subject to the regulatory jurisdiction of the CDFW pursuant to
Section 1600 ofthe Califomia Fish and Game Code; and coastal wetlands subject to the
regulatory jurisdiction of the City of Carlsbad pursuant to the Carlsbad LCP and Coastal
Resource Protection Overlay Zone (CRPOZ) Ordinance.
Potential CDFW jurisdictional boundaries were determined based on the presence of riparian
vegetation or regular surface flow. Streambeds within CDFW jurisdiction were delineated based
on the definition of streambed as "a body of water that flows at least periodically or
intermittently through a bed or channel having banks and supporting fish or other aquatic life.
This includes watercourses having a surface or subsurface flow that supports riparian vegetation"
(Title 14, Secfion 1.72). Riparian habitat is not defined in Title 14, but the section refers to
vegetation and habitat associated with a stream. CDFW jurisdictional habitat includes all
riparian shrub or tree canopy that may extend beyond the banks of a stream.

Potential Carlsbad LCP coastal wetland boundaries were determined using the wetland definition
in Section 30121 of the Cahfomia Coastal Act. "Wetland" means lands within the coastal zone
which may be covered periodically or permanently with shallow water and include saltwater
marshes, freshwater marshes, open or closed brackish water marshes, swamps, mudflats, and
fens. Coastal wetland boundaries were determined based on the presence of a single wetland
criterion, meaning that a dominance of hydrophytic vegetation, hydric soils, or wetland
hydrology was present.
For the purposes of this study, potential USAGE jurisdictional boundaries were determined based
on a dominance of hydrophytic vegetation, presumed hydric soil conditions, and presence of
wetland hydrology indicators within suspected wetlands that abut and are immediately adjacent
to Buena Vista Lagoon, which is a traditional navigable water (TNW).
Plants were identified according to Baldwin et al. (2012), and Galflora (2013) was used to
augment common names. Wetland affiliations of plant species follow The National Wetland
Plant List (Lichvar 2012). Nomenclature used in this report follows Holland (1986) or
Oberbauer (2008) for vegetation communities. Heath (2004) for butterflies, Crother (2008) for
reptiles, the American Ornithologists' Union (2011) for birds, and Baker et al. (2003) for
mammals.

Southern Willow Scrub
Southem willow scmb consists of dense, broadleaved, winter-deciduous stands of trees
dominated by shmbby willows (Salix sp.), usually in association with mule fat {Baccharis
salicifolia). This habitat occurs on loose, sandy or fine gravelly alluvium deposited near stream
channels during flood flows. The southem willow scmb occurs on site is dominated by arroyo
willow {Salix lasiolepis), but also contains non-native species including castor-bean (Ricinus
communis), garden nasturtium {Tropaeolum majus), and wild radish (Raphanus sativus).
Southem willow scmb occurs in the westernmost portion ofthe site at the base of the slope near
the edge of Buena Vista Lagoon and encompasses approximately 0.01 acre (Table 2).
Non-native Grassland
Non-native grassland is dominated by non-native grass species but can also contain native
grasses and native and non-native forbs. Non-native grassland on site consists primarily of
non-native species, predominately rip gut grass (Bromus diandrus) and wild oats (Avena sp.),
with lesser coverage by barley {Hordeum sp.), cheeseweed {Malva parviflord), black mustard
{Brassica nigra), and wild radish. Four native species also were observed: calabazilla
{Cucurbita foetidissima), westem ragweed {Ambrosiapsilostacyha), jimsoimeed {Datura
wrightii), and lemonadeberry {Rhus integrifolia [one individual]). Non-native grassland covers
the majority ofthe site, totaling approximately 0.26 acre (Table 2).

August 5,2013
Non-native Vegetation
Non-native vegetation consists of cultivated plants that have naturalized into otherwise native
habitat areas or were put in place by humans, usually for the purpose of beautification,
windbreaks, or other related purposes, and are no longer maintained. Non-native vegetation on
site consists of a patch of hottentot-fig {Carpobrotus edulis) in the southwestern comer. This
community occupies approximately 0.03 acre on site (Table 2).
Disturbed Land
Disturbed land is devoid of vegetation due to soil disturbance (dirt roads and/or grading) or is
dominated by exotic, annual forbs without a major grass component. Disturbed land on site
consists of bare areas as well as areas supporting a variety of weedy non-natives, including
cheeseweed, Russian thistle {Salsola tragus), spotted spurge {Chamaesyce maculata), filaree
{Erodium sp.), fleabane {Erigeron bonariensis), and castor-bean. Disturbed land comprises
approximately 0.6 acre on site (Table 2).
Developed
Developed land is that where either permanent stmctures and/or pavement have been placed or
maintained landscaping occurs. Approximately 0.02 acre of developed land occurs in the eastem
portion of the site, consisting of a concrete pad (Table 2).
Sensitive Biological Resources
Sensitive biological resources are those generally defined as (1) habitat areas or vegetation
communities that are unique, of relatively limited distribution, or of particular value to wildlife;
and (2) species that have been given special recognition by federal, state, or local govemment
agencies and organizations due to limited, declining, or threatened populations.
Sensitive Vegetation Communities
A single sensitive vegetation community, southem willow scmb, comprises 0.01 acre along the
westem boundary of the site (Figure 4; Table 1).
Sensitive Plant Species
A total of 25 plant species were observed on site during the June 20, 2013 general biological
survey, none of which are federal, state, or HMP sensitive plant species (Attachment A).
The site has very low potential to support any sensitive plant species, and no listed plant species
are expected to occur. Refer to Attachment C for additional discussion regarding the potential
for sensitive plant species to occur.

Sensitive Animal Species
Page 6 of 14
A total of 18 animal species were observed or detected during the June 20, 2013 general
biological survey, including 4 insect, 1 amphibian, 10 bird, and 3 mammal species (Attachment
B). None of the observed or detected species are federal, state, or HMP sensitive animal species
The potential for sensitive animal species to occur on site is considered low due to its small size,
poor habitat quality, and adjacency to existing development on 3 sides. Attachment D further
discusses the potential for sensitive animal species to occur on site. Attachment E provides a
listing and explanation of status codes for both plant and animal species.
Jurisdictional Waters and Wetlands
The information provided below presents HELIX's best efforts to quantify the amount of
potential USAGE, CDFW, and Carlsbad LCP jurisdictional habitats on the project site using
current regulations, written policies, and guidance from the regulatory agencies. Only the
regulating agencies can make a final determination of jurisdictional boundaries.
The 0.01 acre of southem willow scmb occurring on site is considered potential USAGE, CDFW,
and Carlsbad LCP jurisdictional wetland and riparian habitat (Figure 5; Table 3). No other
potential jurisdictional waters or wetlands occur on site.

REGIONAL AND REGULATORY CONTEXT
Biological resources within the project site are subject to federal. State, and local regulations, as
described in fiirther detail below.
Federal
Administered by the USFWS, the federal Endangered Species Act (ESA) provides the legal
framework for listing and protection of species (and their habitats) that are identified as being
threatened or endangered with extinction. Actions that jeopardize threatened or endangered
species and the habitats upon which they rely are considered "take," which ESA Section 9(a)
defines as "to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt
to engage in any such conduct." "Harm" and "harass" are further defined in federal regulations
Enmonmenlal Planning
Letter to Ms. Veronica De Anda Page 7 of 14
August 5, 2013
and case law to include actions that adversely impair or dismpt a listed species' behavioral
patterns.
Federal ESA Sections 4(d)7 and 10(a) regulate actions that could jeopardize threatened or
endangered species. Section 10(a) allows issuance of permits for "incidental" take of threatened
or endangered species, which applies if the taking of a listed species is incidental to and not the
purpose of an otherwise lawful activity. The Carlsbad HMP has been formally approved, which
provides take authorization under Section 10(a). No threatened or endangered species were
observed and none are expected to occur on site.
All migratory bird species that are native to the United States or its territories are protected under
the federal Migratory Bird Treaty Act (MBTA) as amended under the Migratory Bird Treaty
Reform Act (MBTRA) of 2004 (FR Doc. 05-5127). The MBTA is generally protective of
migratory birds but does not actually stipulate the type of protection required. In common
practice, the MBTA is used to place restrictions on disturbance of active bird nests during the
nesting season (generally Febmary 15 to August 31). In addition, the USFWS commonly places
restrictions on disturbances allowed near active raptor nests. The project site does not support
suitable habitat for nesting raptors, as no large trees were observed on site and on site grassland
is too small and disturbed for ground-nesting raptors. The site may support nesting habitat for
other bird species, particularly in shmb habitat along the edge of the lagoon. However, nesting
birds are unlikely to use the proposed development area as it supports only herbaceous
vegetation, and is highly disturbed, often being used by nearby residents as a place to walk their
dogs.
Federal wetland regulation applicable to the project site is guided by the Clean Water Act (GWA).
The purpose of the GWA is to restore and maintain the chemical, physical, and biological
integrity of all waters of the U.S. Permitting for projects filling waters of the U.S. (including
wetlands) is overseen by the USAGE under Section 404 of the GWA. Projects are typically
permitted on an individual basis or are covered under one of several approved general or
Nationwide Permits. Southem willow scmb occurring on site may fall under the jurisdiction of
the USAGE.
State
Primary environmental legislation in California is found in the California Environmental Quality
Act (CEQA) and its implementing guidelines (State CEQA Guidelines), requiring that projects
with potential adverse effects or impacts on the environment undergo environmental review.
Adverse impacts to the environment are typically mitigated as a result of the environmental
review process in accordance with existing laws and regulations. Under CEQA, impacts
associated with a proposed project or program are assessed with regard to significance criteria
determined by the CEQA Lead Agency and pursuant to State CEQA Guidelines. The City is the
Lead Agency under CEQA for the proposed project.
The Califomia Endangered Species Act (CESA) is similar to the federal ESA in that it contains a
process for listing of species and regulating potential impacts to listed species. Section 2081 of
HELIX
Environmental f^anning
Letter to Ms. Veronica De Anda Page 8 of 14
August 5,2013
the CESA authorizes the CDFW to enter into a memorandum of agreement for take of listed
species for scientific, educational, or management purposes. No state-listed plant or animal
species are expected to occur on site.
The Native Plant Protection Act (NPPA) enacted a process by which plants are listed as rare or
endangered. The NPPA regulates collection, transport, and commerce in listed plants. The
Califomia ESA followed the NPPA and covers both plants and animals determined to be
threatened or endangered with extinction. Plants listed as rare xmder the NPPA were designated
threatened under the Califomia ESA. The site is not likely to support any listed plants.
Pursuant to Califomia Fish and Game Code Section 3503, it is tmlawfiil to take, possess, or
needlessly destroy the nest or eggs of any bird, except as otherwise provided by the code or any
regulation made pursuant thereto. Raptors (birds of prey) and owls and their active nests are
protected by California Fish and Game Code Section 3503.5, which states that it is unlawfiil to
take, possess, or destroy any birds of prey or to take, possess, or destroy the nest or eggs of any
such bird unless authorized by the CDFW. In common practice, CDFW places timing
restrictions on clearing of vegetation, as well as restrictions on disturbances allowed near active
raptor nests.
Under Section 401 of the federal GWA, an applicant for a federal permit that may result in a
discharge to a water body must obtain certification fi-om the state that the proposed activity will
comply with state water quality standards and water quality objectives. Section 401 provides the
Regional Water Quality Control Board (RWQGB) with regulatory authority to certify or deny the
proposed activity. A Section 401 Certification must be obtained prior to issuance of a 404 Permit.
The CDFW regulates alterations or impacts to streambeds or lakes under Califomia Fish and
Game Code 1602. The CDFW requires a Streambed/Lake Alteration Agreement (SAA) for
projects that will divert or obstmct the natural flow of water; change the bed, chaimel, or bank of
any stream; or use any material from a streambed. The SAA is a contract between the applicant
and CDFW stating what can be done in the riparian zone and stream course (Califomia
Association of Resource Conservation Districts 2002). Any impacts to CDFW habitat would be
regulated under Califomia Fish and Game Code 1602 and require an SAA. The project would be
set back at least 100 feet from the edge of CDFW habitat (southem willow scmb) and would not
require an SAA.
The Califomia Coastal Act provides for the protection of environmentally sensitive habitat
identified by the CDFW from developments in the coastal zone. The California Coastal Act is
Califomia's coastal zone management program under the federal Coastal Zone Management Act.
The Califomia Coastal Act establishes the California Coastal Commission (CGG) as having
jurisdiction over Califomia's coastal zone. The California Coastal Act identifies environmentally
sensitive habitat areas (ESHA) as any area in which plant or animal life or their habitats are
either rare 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. Compliance
with the Califomia Coastal Act is ensured for specific development projects in the coastal zone
through issuance of a Coastal Development Permit (GDP). In most incorporated areas within the
HELIX
Entimnmenlal Plannina
Letter to Ms. Veronica De Anda Page 9 of 14
Augusts, 2013
coastal zone, compliance with the Coastal Act is regulated by local govemment through the
implementation of a certified LCP. The local govemment typically issues CDPs, unless a project
is located within a deferred certification area, such as the Agua Hedionda Lagoon segment ofthe
Carlsbad LCP. CDPs are issued by the CGG in deferred certification areas of the certified LCP.
The City implements their approved Carlsbad LCP in regulating developments within the coastal
zone according to the Coastal Resource Protection Overlay Zone Ordinance, as discussed below.
The CDPs issued by the City are appealable to the CGG only if they are located within an
appeals area. Mitigation would be required for impacts to coastal wetlands and ESHA protected
under the Carlsbad LCP and Coastal Resource Protection Overlay Zone Ordinance.
Local
Multiple Habitat Conservation Program
The Multiple Habitat Conservation Program (MHCP) is a regional, comprehensive, jurisdictional
plaiming program designed to develop an ecosystem preserve in the incorporated areas of
northwestem San Diego County. The overall goal of the plan is to "maintain biodiversity and
ecosystem health in the region while maintaining quality of life and economic growth
opportunities." The MHCP Plan was adopted by the San Diego Association of Govemments
(SANDAG) in 2003. Within this plan, city-wide subarea plans describe the specific
implementing mechanisms each city will institute for the MHCP. Carlsbad's MHCP Subarea
Plan, the Carlsbad HMP, was approved in 2004 and is further discussed below.
Carlsbad HMP
The Carlsbad HMP provides property owners with take authorizations for HMP-covered listed
species. The HMP addresses potential impacts to native species and habitats (and some
non-native habitats) and provides mitigation options that satisfy ESA and CESA. The primary
objective ofthe HMP is to preserve the diversity of habitat and protect sensitive biological
resources within the City while allowing for additional development. The plan identifies and
maintains a preserve system that allows for the sustained existence of animals and plants at both
the local and regional levels. The HMP preserve is a network of large habitat blocks with
interconnecting linkages. The areas covered by the Carlsbad HMP include hard-line preserve
areas. Core Areas 1 through 8, Linkages A through F, and Local Facility Management Zones
(LFMZ) 1 through 25.
The site is located with LFMZ 1 of the Carlsbad HMP, just outside of the Core Area 1 boundary
(Figure 6). Gore 1 consists of Buena Vista Lagoon and adjoining wetland and upland habitat.
Buena Vista Lagoon and its surrounding vegetation provide habitat for critical populations of
Califomia least tern {Sterna antillarum browni), westem snowy plover {Charadrius alexandrinus
nivosus), light-footed clapper rail {Rallus longirostris levipes), American peregrine falcon {Falco
peregrinus anatum), and white-faced ibis {Plegadis chihi). As a result, the lagoon and its
associated vegetation have been designated "Hardline Preserve Areas" by the City and
"Conserved Lands" by the CDFW
HELIX
Enviimmental Plarnilrm
Letter to Ms. Veronica De Anda Page 10 of 14
August 5, 2013
Pursuant to the Carlsbad HMP, LFMZ 1 is almost entirely developed, containing scattered
fragments of natural vegetation, including major and critical stands of riparian habitat and
scattered patches of coastal sage scmb, non-native grassland, maritime succulent scmb, salt
marsh, and freshwater marsh.
Conservation of the majority of sensitive habitats in or contiguous with biological core areas is
the primary HMP Conservation Goal for LFMZ 1. These include:
• No net loss of wetland habitat;
• Preserving coastal sage scmb and maritime succulent scmb adjacent to Buena Vista and Agua
Hedionda Lagoons; and
• Retaining and managing natural habitats adjacent to the lagoons to buffer wetland resources
from adverse effects and to provide upland nesting habitat for pond turtles and other HMP
species.
HMP Coastal Zone Standards
Pursuant to the Carlsbad HMP, additional conservation standards apply to projects in the coastal
zone. This project is within the coastal zone and the following standards are applicable to the
project.
Upland Habitat Mitigation Requirements
Mitigation for impacts to upland vegetation communities must be consistent with the Carlsbad
HMP. Standard mitigation ratios are outlined in Table 11 of the HMP.
Buffers and Fuel Modification Zones
Buffers shall be provided between preserved areas and development. The minimum buffer width
for riparian areas is SO feet and wetlands require a 100-foot buffer width. No development,
grading, or alterations, including clearing of vegetation, shall occur in the buffer area with two
exceptions: no fuel modification shall take place within 50 feet of riparian areas or wetlands,
and recreation trails and public pathways may occur within the 15 feet closest to the
development provided it is consistent with the preservation goals of the preserved habitat and
appropriate measures are taken for physical separation from sensitive areas. Buffer areas that do
not contain native habitat shall be landscaped with native plants. Signage and barriers shall be
required to minimize edge effects.
Grading and Landscaping Requirements
Grading activity shall be prohibited during the rainy season (October 1 to April 1). The City
Engineer may extend the October 1 deadline if specific provisions are met regarding special
erosion control measures. A coastal development permit or permit amendment would allow
grading activities during the winter if resource agencies prohibit grading on site during the
summer to protect endangered or rare species. All graded areas shall have temporary or
HELIX
Eaviranmenta! Planning
Letter to Ms. Veronica De Anda Page 11 of 14
Augusts, 2013
permanent landscaping installed prior to October 1 and shall be maintained and replanted if not
well-established by December 1 following the initial planting.
Carlsbad LCP
The City uses its Carlsbad LCP as a planning tool to guide development in the coastal zone, in
partnership with the CGG. The LCP contains the ground mles for fixture development and the
protection of coastal resources. The Carlsbad LCP includes two main components: a land use
plan, and related implementing measures including a zoning map and zoning ordinance. In
particular, the local coastal land use plans include measures specifically intended to protect
natural open space resources, scenic resources, agricultural lands, and public access rights.
Carlsbad's LCP is consistent with the Carlsbad General Plan, but it is a separate document
containing separate land use policies and implementation measures which must also be complied
with in addition to the General Plan. The City's coastal zone has been divided into 6 segments
and each segment is regulated by separate LCPs. Nearly all development proposals within the
coastal zone, from removal of natural vegetation to the constmction of master planned
communities, require the approval of a GDP in addition to any other permits or entitlements. The
City issues CDPs in all adopted Carlsbad LCP segments within their jurisdictional boundaries
with the exception of the Agua Hedionda Lagoon segment of the Carlsbad LCP, which is a
deferred certification area. CDPs in the Agua Hedionda Lagoon segment of the Carlsbad LCP
are issued by the CGG. CDPs issued by the City are appealable to the CGG only if they are
located within an appeals area. In conformance with the LCP, the City of Carlsbad regulates
developments within the coastal zone, including pipelines, according to the CRPOZ
Ordinance. The CRPOZ Ordinance requires that project applicants obtain a GDP.
According to the Carlsbad LCP Policy 7-6, an access trail is required to be provided along the
southem shoreline of Buena Vista Lagoon (City 1996). Each parcel adjacent to the lagoon is
required to make an offer of dedication of lateral accessways, irrevocable for a term of 21 years,
and shall be of at least 25 feet in width upland from environmentally sensitive area and any
required buffers thereto.
According to the Mello II segment of the Carlsbad LCP, the site itself has been planned and
zoned for residential use, but the LCP requires that development be set back a minimum of 100
feet from coastal wetlands in order to buffer sensitive habitat areas (City 1996). The southem
willow scmb that occurs in the extreme westem portion ofthe project site would qualify as
coastal wetlands requiring a minimum 100-foot development setback.

FINDINGS AND RECOMMENDATIONS
Carlsbad HMP Consistency
Constmction of the proposed single-family residence would be consistent with the primary HMP
Conservation Goal for LFMZ 1, in that the project would not result in the loss of wetland habitat,
would not impact sage scmb or maritime succulent scmb adjacent to Buena Vista Lagoon, and
would not otherwise impact natural habitats adjacent to the lagoon.
Project development would be set back a minimum of 100 feet upslope from the edge of wetland
habitat (i.e. southem willow scmb; Figures 4 and 5), thus being consistent with the HMP
requirement for a minimum 100-foot buffer width between wetlands and development.
No HMP species were observed or are expected on site, and the project site is not expected to
provide suitable nesting habitat for any HMP species, thus there are no specific management
recommendations for HMP species that apply to the project.
No sensitive vegetation communities occur within the proposed impact area. In accordance with
the Carlsbad HMP, the applicant shall pay a per-acre in-lieu mitigation fee for impacts to
non-native grassland and disturbed lands on the project site, in an amount to be determined by
the City Council. Current HMP mitigation fees are $14,878 per acre for non-native grassland
and $2,976 per acre for disturbed lands (pursuant to City of Carlsbad Development Fees,
effective September 1, 2012 and revised March 14, 2013).
Buffer areas that do not contain native habitat shall be landscaped with native plants. Signage
and barriers are required to minimize edge effects.
Carlsbad LCP Consistency
Consistent with the Carlsbad LCP, development on the project site would be set back a minimum
of 100 feet from wetland habitat.
Other Applicable Regulations
In order to comply with the MBTA and California Fish and Game Code, it is recommended that
the project clear vegetation outside of the nesting bird season (generally Febmary 1 through
August 31), or that a preconstmction nesting bird survey be conducted within three days prior to
any clearing, gmbbing, or grading activities. The pre-constmction nesting bird survey would
identify the locations of any active nests within the proposed development area. Active nests
would need to be avoided until the young have fledged or the nest is otherwise abandoned.

CONCLUSION
The project site would implement required setbacks from wetland vegetation along Buena Vista
Lagoon and would not impact wetlands, sensitive upland habitat, or sensitive plant or animal
species. Mitigation for impacts to non-native grassland and disturbed lands would be through
the City's in-lieu mitigation fee as designated in the HMP.
