Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, Califomia
Dear Mr. Farrow:
In response to comments received during the preliminary review application with the City of
Carlsbad (City), this letter report provides a description of the current site conditions, an assessment
of potential biological resources associated with the subject property (i.e., Assessor's Parcel Number
155-221-12-00), and a discussion of any potential biological resources that may be subject to
regulation under the California Coastal Act. This letter report is prepared in accordance with the
City's Habitat Management Plan (HMP)for Natural Communities in the City of Carlsbad (City of
Carlsbad 2004) and Guidelines for Biological Studies (City of Carlsbad 2008). The project site is
located within the coastal zone; the northwest comer of the project site is within Core Area 1
according to the City HMP, but it does not fall within a hardline area (Buena Vista Lagoon; City of
Carlsbad 2004). Dudek conducted a biological study of the property on November 2, 2017, and
February 2, 2018; the methods, details, and results of the investigations are provided herein.
The property (i.e., site) occupies 0.75 acres and is located along the north side of Laguna Drive
approximately 0.5 miles west of Interstate 5 and 0.4 miles east of the Pacific Ocean (Figure 1 ).
The site is located in Section 01 in Township 12 South, Range 5 West in the U.S. Geological
Service 7.5-minute series topographic San Luis Rey quadrangle map. The site is bordered by the
Buena Vista Lagoon to the north/northwest, by Laguna Drive to the south, and development to
the east and west (Figure 1 ).
PROJECT DESCRIPTION
The proposed project includes the demolition of an existing office building and single-family dwelling,
and construction of 13 new detached three-story, single family homes (average of 1,644 square feet
each) with roof decks on an approximately 0.75-acre site. The lot will be subdivided into 13 individual
air space site condominiums. All lots will have individual water, gas, electricity, telecom, and sewer
services that are brought into the site via the driveway, which will serve as a shared access and mutual
maintenance/utility easement. There are no common areas proposed as part of the project. The project
emphasizes sustainability and walkability by recognizing its location as not being car dependent with

mass transit nearby. Garage spaces are provided and will include a lift to allow for a second private
vehicle. The proposed project also includes an open space easement and a 25-foot public access
easement within the open space. The California Coastal Commission (CCC) requested that the public
access easement be located at the bottom of the slope to be consistent with nearby properties. While
this location is not consistent with the HMP Coastal Zone Standards, the City will defer to the CCC.
The proposed project would remove non-native plants in the wetland buffer and restoration of this area
with native plants. While not formally required by the Fire Department, there is a fuel modification
zone (FMZ) B-3 within a portion of the open space.
REGULATORY CONTEXT
California Endangered Species Act
The California Department of Fish and Wildlife (CDFW) administers the California Endangered
Species Act (CESA), which prohibits the "take" of plant and animal species designated by the
California Fish and Game Commission as endangered or threatened in the state of California.
Under CESA Section 86, take is defined as "hunt, pursue, catch, capture, or kill, or attempt to hunt,
pursue, catch, capture, or kill." CESA Section 2053 stipulates that state agencies may not approve
projects that will 'jeopardize the continued existence of any endangered species or threatened
species, or result in the destruction or adverse modification of habitat essential to the continued
existence of those species, ifthere are reasonable and prudent alternatives available consistent with
conserving the species or its habitat which would prevent jeopardy."
CESA defines an endangered species as "a native species or subspecies of a bird, mammal, fish,
amphibian, reptile, or plant which is in serious danger of becoming extinct throughout all, or a
significant portion, of its range due to one or more causes, including loss of habitat, change in habitat,
overexploitation, predation, competition, or disease." CESA defines a threatened species as "a native
species or subspecies of a bird, mammal, fish, amphibian, reptile, or plant that, although not presently
threatened with extinction, is likely to become an endangered species in the foreseeable future in the
absence of the special protection and management efforts required by this chapter. Any animal
determined by the [California Fish and Game] Commission as rare on or before January 1, 1985, is a
threatened species." A candidate species is defined as "a native species or subspecies of a bird,
mammal, fish, amphibian, reptile, or plant that the Commission has formally noticed as being under
review by the department for addition to either the list of endangered species or the list of threatened
species, or a species for which the Commission has published a notice of proposed regulation to add
the species to either list." CESA does not list invertebrate species.
CESA authorizes the taking of threatened, endangered, or candidate species if take is incidental to
otherwise lawful activity and if specific criteria are met. These provisions also require CDFW to
coordinate consultations with U.S. Fish and Wildlife Service (USFWS) for actions involving federally

listed species that are also state-listed species. In certain circumstances, CESA allows CDFW to adopt
a CESA incidental take authorization as satisfactory for California Environmental Quality Act (CEQA)
purposes based on finding that the federal permit adequately protects the species and is consistent with
state law.
A CESA permit may not authorize the take of fully protected species that are protected in other
provisions of the California Fish and Game Code, discussed further as follows.
Federal Endangered Species Act
The federal Endangered Species Act (ESA) of 1973 (16 U.S.C. 1531 et seq.), as amended, is
administered by USFWS for most plant and animal species, and by the National Oceanic and
Atmospheric Administration National Marine Fisheries Service for certain marine species. This
legislation is intended to provide a means to conserve the ecosystems upon which endangered and
threatened species depend and provide programs for the conservation of those species, thus
preventing extinction of plants and wildlife. ESA defines an endangered species as "any species
that is in danger of extinction throughout all or a significant portion of its range." A threatened
species is defined as "any species that is likely to become an endangered species within the
foreseeable future throughout all or a significant portion of its range." Under the federal ESA, it is
unlawful to take any listed species, and take is defined as "harass, harm, pursue, hunt, shoot,
wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct."
ESA allows for the issuance of incidental take permits for listed species under Section 7, which is
generally available for projects that also require other federal agency permits or other approvals,
and under Section 10, which provides for the approval of habitat conservation plans (HCPs) on
private property without any other federal agency involvement. Upon development of an HCP,
USFWS can issue incidental take permits for listed species.
Migratory Bird Treaty Act
The Migratory Bird Treaty Act was originally passed in 1918 as four bilateral treaties, or
conventions, for the protection of a shared migratory bird resource. The primary motivation for
the international negotiations was to stop the "indiscriminate slaughter" of migratory birds by
market hunters and others. Each of the treaties protects selected species of birds and provides for
closed and open seasons for hunting game birds. The Migratory Bird Treaty Act protects over 800
species of birds (16 U.S.C. 703-712). Two species of eagles that are native to the United States,
the bald eagle (Haliaeetus leucocephalus) and golden eagle (Aquila chrysaetos), were granted
additional protection within the United States under the Bald and Golden Eagle Protection Act (16
U.S.C. 668-668d) to prevent the species from becoming extinct.

Jurisdictional Waters of the United States, including Wetlands
U.S. Army Corps of Engineers
Pursuant to Section 404 of the Clean Water Act, the U.S. Army Corps of Engineers (ACOE)
regulates the discharge of dredged and/or fill material into "waters of the United States." The term
waters of the United States is defined in the in ACOE regulations as follows:
• All waters which are currently used, or were used in the past, or may be susceptible to
use in interstate or foreign commerce, including all waters which are subject to the ebb
and flow of the tide
• All interstate waters including interstate wetlands
• All other waters such as intrastate lakes, rivers, streams (including intermittent
streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa
lakes, or natural ponds, the use, degradation or destruction of which could affect foreign
commerce, including any such waters:
a. Which are or could be used by interstate or foreign travelers for recreational or
other purposes
b. From which fish or shellfish are or could be taken and sold in interstate or
foreign commerce
c. Which are used or could be used for industrial purpose by industries in interstate
commerce
• All impoundments of waters otherwise defined as waters of the United States under the
definition
• Tributaries of waters identified in paragraphs (a) (I) through (4) of this section
• The territorial seas
• Wetlands adjacent to waters ( other than waters that are themselves wetlands) identified
in paragraphs (a)(l) through (6) of this section (33 CFR 328.3(a)).
The term "wetlands" (a subset of waters) is defined in 33 CFR 328.3(b) as "those areas that are
inundated or saturated by surface water or groundwater at a frequency and duration sufficient to
support, and that under normal circumstances do support, a prevalence of vegetation typically
adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs,
and similar areas."

Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
In the absence of wetlands, the limits of ACOE jurisdiction in non-tidal waters, such as intermittent
streams, extend to the ordinary high water mark, which is defined in 33 CFR 328.3(e) as "that line
on the shore established by the fluctuations of water and indicated by physical characteristics such
as a clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction
of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider
the characteristics of the surrounding areas."
On June 5, 2007, ACOE and the U.S. Environmental Protection Agency (EPA) released guidance
on the geographic extent of jurisdiction under the federal Clean Water Act, based on the U.S.
Supreme Court's interpretation of the Clean Water Act in Rapanos v. United States and Carabell
v. Army Corps of Engineers, 126 S. Ct. 2208 (2006) (ACOE and EPA 2008). The ACOE/EPA
guidance states that ACOE will regulate traditional navigable waters (TNWs), adjacent wetlands
(directly abutting TNWs), and relatively permanent waters tributary to TNWs and adjacent
wetlands. Non-navigable tributaries that are not relatively permanent nor are wetlands adjacent to
such tributaries will be assessed on a case-by-case basis to determine whether they have a
"significant nexus" to a TNW. A significant nexus occurs when waters, including adjacent
wetlands, affect the chemical, physical, or biological integrity ofTNWs. Factors considered during
the significant nexus evaluation include:
1. Flow characteristics and functions of the tributary itself in combination with the functions
performed by any wetlands adjacent to the tributary
2. Hydrologic characteristics, including but not limited to volume, duration, and frequency of
flow; proximity to TNW; size of the watershed; average annual rainfall; and average annual
winter snow pack
3. Ecological characteristics including but not limited to the ability of tributaries to carry
pollutants and flood waters to TNW s, provide aquatic habitat that support TNW s, trap and
filter pollutants or store flood waters, and maintain water quality
The discharge of dredge or fill material into waters, including wetlands, requires authorization
from ACOE prior to impacts.
For impacts to wetlands or waters under ACOE jurisdiction, either an Individual Permit or a
Nationwide Permit (NWP) would be required in accordance with Section 404 of the Clean Water
Act. The NWP is issued for a variety of projects having minimal impacts to jurisdictional waters
of the United States, including wetlands. If it is determined that the project qualifies for use of the
NWP program, a Pre-Construction Notification must be submitted to ACOE, if required, that
includes a project description, a purpose and need statement for the project, a description of efforts
to avoid and minimize impacts to jurisdictional areas, and a conceptual mitigation and monitoring

plan. Additional environmental review under the National Environmental Policy Act (NEPA) is
not required for a NWP. As a result, once ACOE has determined that the application is complete
and the project meets the requirements of the NWP, authorization to use the NWP can be issued.
If a project fails to comply with the terms and regulations specified in the NWP guidelines, then
an Individual Permit application to ACOE must be prepared. The application for the Individual
Permit includes a project description, a purpose and need statement for the project, a description
of efforts to avoid and minimize impacts to jurisdictional areas, and a conceptual mitigation and
monitoring plan. The Individual Permit application also must include an alternatives analysis that
would be completed to allow ACOE to make findings in accordance with Section 404(b )(1 ). Once
the application is determined to be complete and ACOE accepts the 404(b )( 1) alternatives analysis,
ACOE will issue a public notice for the Individual Permit. The NEPA-required public comment
period lasts for 45 days, and all responsible federal agencies and adjacent property owners are
notified. When the public comment period is closed, the applicant has 30 days to respond to the
comments received by ACOE. Prior to issuance of the Individual Permit, ACOE must complete
an environmental assessment to comply with the requirements of NEPA. The environmental
assessment and Finding of No Significant Impact is usually completed by the applicant's
consultant and finalized by ACOE staff. Following ACOE internal review of the environmental
assessment, ACOE will issue the permit.
California Department of Fish and Wildlife
Pursuant to Section 1602 of the California Fish and Game Code, CDFW regulates all diversions,
obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake
that supports fish or wildlife.
In 14 CCR 1.72, CDFW defines a "stream" (including creeks and rivers) as "a body of water that
flows at least periodically or intermittently through a bed or channel having banks and supports
fish or other aquatic life. This includes watercourses having surface or subsurface flow that
supports or has supported riparian vegetation."
In 14 CCR 1.56, CDFW's definition of "lake" includes "natural lakes or man-made reservoirs."
Diversion, obstruction, or changes to the natural flow or bed, channel, or bank of any river, stream,
or lake that supports fish or wildlife requires authorization from CDFW by means of entering into
an agreement pursuant to Section 1602 of the California Fish and Game Code.
California Regional Water Quality Control Board
Pursuant to Section 401 of the federal Clean Water Act, the Regional Water Quality Control Board
(RWQCB) regulates discharging waste, or proposing to discharge waste, within any region that
DUDEK 6
10746

Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
could affect a "water of the state" (California Water Code, Section 13260(a)), pursuant to
provisions of the Porter-Cologne Water Quality Control Act (Porter-Cologne Act). Waters of the
state are defined as "any surface water or groundwater, including saline waters, within the
boundaries of the state" (California Water Code, Section 13050(e)). Before ACOE will issue a
Clean Water Act Section 404 permit, applicants must receive a Clean Water Act Section 401 Water
Quality Certification from the RWQCB. If a Clean Water Act Section 404 permit is not required
for the project, the RWQCB may still require a permit (i.e., Waste Discharge Requirement) for
impacts to waters of the state under the Porter-Cologne Act.
California Coastal Act
Under the California Coastal Act, the CCC regulates the "coastal zone" and requires a coastal
development permit for almost all development within this zone. From 3 miles seaward, the coastal
zone generally extends approximately 1,000 miles inland. In less developed areas, it can extend
up to 5 miles inland from mean high-tide line but can also be considerably less than 1,000 yards
inland in developed areas.
The California Coastal Act also protects designated sensitive coastal areas by providing additional
review and approvals for proposed actions in these areas. The act defines wetlands as " .. .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 ... " The California Coastal Act allows diking, filling, or dredging of wetlands
for certain uses, such as restoration. The act also directs each city or county within the coastal zone
to prepare a local coastal permit (LCP) for CCC certification (CERES 2010). Under approved
LCPs, jurisdictions can independently approve LCPs for projects developed consistent with the
approved LCP. The City has an approved LCP.
Local Conservation Plans
North County Multiple Habitat Conservation Program
The North County Multiple Habitat Conservation Program (MHCP) is a long-term regional
conservation plan established to protect sensitive species and habitats in northern San Diego
County. The MHCP is divided into seven subarea plans-----one for each jurisdiction within the
MHCP-that are permitted and implemented separately from one another. The City of Carlsbad
is the only city under the MHCP that has an approved and permitted subarea plan (i.e., the City of
Carlsbad HMP (City of Carlsbad 2004)).
DUDEK 7

Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
The MHCP sets forth general and subarea conditions of coverage that must be met for each covered
species for the City to obtain take authorization. These conditions can be found in Appendix C of
the Carlsbad HMP.
City of Carlsbad Habitat Management Plan
The Carlsbad HMP was adopted by the City in December 1999, and the final approvals from USFWS
and CDFW, including implementing agreement and terms and conditions, were granted in November
2004. The purpose of the HMP is to guide the design, management, monitoring, and public use of the
preserve system. The HMP calls for 6,478 acres of natural habitat to be preserved within the City, as
well as an additional 308 acres of habitat for the coastal California gnatcatcher (Polioptila californica
californica) within the City of Carlsbad's or the county's gnatcatcher core area. The Carlsbad HMP
identifies local facility management zones, which were developed based on the distribution of existing
vegetation communities and sensitive species. The zones were further broken down into HMP cores,
linkages, and special resource areas.
The project site is located within Local Facility Management Zone 1, and the northwest portion
of the site is within the HMP Core 1 Focus Planning Area (Figure 2). The Core 1 U.S. Focus
Planning Area is approximately 206 acres in size and includes the Buena Vista Lagoon and
adjoining wetland and upland habitats in northwest Carlsbad. The HMP describes Core 1 as
almost entirely developed but containing scattered fragments of natural vegetation, including
major and critical stands of riparian, as well as some scattered patches of coastal sage scrub,
non-native grassland, maritime succulent scrub, saltmarsh, and freshwater marsh. Some coastal
sage scrub areas within Core 1 support California gnatcatchers. Much of the remaining
vegetation is on slopes adjoining Buena Vista and Agua Hedionda Lagoons, thus contributing to
the biological value of the lagoon watersheds. Buena Vista and Agua Hedionda Lagoons support
major or critical populations of western pond turtle (Actinemys marmorata), white-faced ibis
(Plegadis chihi), western snowy plover (Charadrius alexandrinus nivosus), and California least
tern (Sternula antillarum browni). The lagoons also provide foraging habitat for the American
peregrine falcon (Falco peregrinus anatum) and California brown pelican (Pelecanus
occidentalis californicus). The HMP Goals for the Core 1 are as follows:
Conserve the majority of sensitive habitats in or contiguous with biological core
areas, including no net loss of wetland habitat, and preserve, coastal sage scrub and
maritime succulent scrub adjacent to the lagoons. Retain and manage natural
habitats adjacent to lagoons to buffer wetland resources from adverse effects and
provide upland nesting habitat for pond turtles and other HMP species.

The project site is not located within an existing or proposed hardline conservation area; however,
the site is located adjacent to an existing hardline conservation area associated with the Buena
Vista Lagoon. Buffers within the Coastal Zone shall be provided between all habitat from the
delineated edge of wetland or riparian areas.
The HMP's conditions for coverage provide the following guidelines for projects adjacent to
habitat occupied by least Bell's vireo (Vireo bellii pusillus) (City of Carlsbad 2004, Section
6.A(f)). As stated in the HMP:
Biological buffer of at least 100 feet shall be maintained adjacent to occupied least
Bell's vireo habitat, measured from the outer edge of riparian vegetation. For
wetlands and riparian areas possessing an unvegetated bank or steep slope (greater
than 25 per cent), the buffer shall be measured from the top of the bank or steep
slope rather than the edge of habitat, unless there is at least 50 feet between the
riparian or wetland area and the toe of the slope. If the toe of the slope is less than
50 feet from the wetland or riparian area, the buffer shall be measured from the top
of the slope. Within this 100-foot buffer, no new development shall be allowed, and
the area shall be managed for natural biological values as part of the preserve
system. Buffers less than 100 feet shall require written concurrence of the USFWS
and CDFG within 30 days ofreceipt of written request for concurrence by the local
jurisdiction.
Wetland Buffers
Wetland buffers generally refer to an area that extends perpendicularly into upland areas from the
delineated edge of wetland or riparian areas. Wetland buffer areas establish an upland zone
adjacent to wetlands designed to avoid and minimize indirect effects on wetland functions ( e.g.,
species habitat, water quality maintenance, flood capacity). The Carlsbad HMP and LCP include
the following provisions requiring wetland buffers.
Buffers shall be provided between all preserved habitat areas and development.
Minimum buffer widths shall be provided as follows:
DUDEK
a. 100 feet for wetlands
b. 50 feet for riparian areas
c. 20 feet for all other native habitats ( coastal sage scrub, southern maritime
chaparral, maritime succulent scrub, southern mixed chaparral, native
grassland, oak woodland).

Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
Any proposed reductions in buffer widths for a specific site shall require sufficient information to
determine that a buffer of lesser width will protect the identified resources. Such information shall
include, but is not limited to, the size and type of the development and/or proposed mitigation
( e.g., planting of vegetation or the construction of fencing) that will also achieve the purposes of
the buffer. The City, CDFW, the USFWS, and the CCC staff shall be consulted in such buffer
reduction determinations.
City Guidelines for Riparian and Wetland Buffers provides additional guidance for the planning
of wetland buffers. Within the coastal zone, protective buffers shall be a minimum of 50 feet in
width surrounding riparian habitats and 100 feet in width surrounding jurisdictional wetlands. As
previously noted and in accordance with Condition 7-11 of the HMP, the protective buffer for
wetlands and riparian areas possessing an unvegetated bank or steep slope (more than 2-5%) shall
be measured from the top of the bank or steep slope rather than the edge of habitat. Buffers should
be 100 feet from the edge of riparian or oak habitat occupied by the least Bell's vireo, southwestern
willow flycatcher (Empidonax traillii extimus), or Harbison dun skipper butterfly (Euphyes vestris
harbisoni) (HMP D-91). The City designates three potential zones within wetland buffers:
protection zone ( extending a minimum of 50 feet from the wetland/riparian edge), separation zone
(if required, extending from 50 feet to 100 feet from the wetland/riparian edge), and transition zone
(if required). The following uses are considered allowable in the wetland buffer: habitat
restoration, stormwater control and flood control facilities and associated access roads, bridge
crossings, utilities, trails, and passive recreation facilities. A process for identifying alternative
buffer configurations is also identified in the guidelines. The guidelines for projects in the coastal
zone are the same as those previously listed.
Buffer widths shall be measured from the edge of preserved habitat nearest the development to the
closest point of development. For wetlands and riparian areas possessing an unvegetated bank or
steep slope (greater than 40% with a 25-foot elevation differential), the buffer shall be measured
from the top of the bank or steep slope rather than the edge of habitat, unless there is at least 50
feet between the riparian or wetland area and the toe of slope. If the toe of the slope is less than 50
feet from the wetland or riparian area, the buffer shall be measured from the top of the slope. As
previously discussed, in circumstances where application of this buffer would preclude reasonable
use of a property, alternative buffer solutions may be negotiated with the City, CCC, and wildlife
agencies.

California Environmental Quality Act
California Environmental Quality Act Guidelines 15380
CEQA requires identification of a project's potentially significant impacts on biological
resources and ways that such impacts can be avoided, minimized, or mitigated. The act also
provides guidelines and thresholds for use by lead agencies for evaluating the significance
of proposed impacts.
CEQA Guideline 15380(b)(l) defines endangered animals or plants as species or subspecies
whose "survival and reproduction in the wild are in immediate jeopardy from one or more
causes, including loss of habitat, change in habitat, overexploitation, predation, competition,
disease, or other factors" ( 14 CCR 15000 et seq.). A rare animal or plant is defined in CEQA
Guideline 15 3 80(b )(2) as a species that, although not presently threatened with extinction,
exists "in such small numbers throughout all or a significant portion of its range that it may
become endangered if its environment worsens; or ... [t]he species is likely to become
endangered within the foreseeable future throughout all or a significant portion of its range
and may be considered 'threatened' as that term is used in the federal Endangered Species
Act." Additionally, an animal or plant may be presumed to be endangered, rare, or threatened
if it meets the criteria for listing, as defined further in CEQA Guideline 15380( c ).
CDFW recognizes that all plants with California Rare Plant Rank IA, 1B, and 2 of the CNPS
Inventory of Rare and Endangered Plants in California (CNPS 2018) may meet the criteria for
listing as threatened or endangered and should be considered under CEQA (CDFW 2018). Some
of the California Rare Plant Rank 3 and 4 plants meet the criteria for determination as "rare" or
"endangered" as defined in Section 1901, Chapter 10 (Native Plant Protection Act), Division 2, of
the California Fish and Game Code, as well as Section 2062 and Section 2067, Chapter 1.5
(CESA), Division 3. Therefore, consideration under CEQA for these California Rare Plant Rank
3 and 4 species is strongly recommended by CNPS (CNPS 2018).
The criteria used to determine the significance of impacts to biological resources under CEQA are
provided in Chapter 5, Anticipated Project Impacts.
Special-Status Plants and Wildlife
Species that are federally listed or state-listed as endangered or threatened are considered special-
status species within this draft conceptual alternatives screening analysis for biological resources.
Some mammals and birds are protected by the state as fully protected species, as described in the
California Fish and Game Code, Sections 4700 and 3511, respectively. Fully protected species

may not be taken or possessed without a permit from the California Fish and Game Commission,
and no permit is available for the incidental take of a fully protected species. Species considered
state candidates for listing as threatened or endangered are subject to the taking prohibitions and
provisions under CESA as if the species were listed.
Special-Status Vegetation Communities
Section IV, Appendix G (Environmental Checklist Form) of the CEQA Guidelines (14 CCR 15000
et seq.) requires an evaluation of impacts to "any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations, or by the California
Department of Fish and Game or the U.S. Fish and Wildlife Service." For purposes of this analysis,
riparian is defined by the National Research Council's 2002 publication Riparian Areas: Functions
and Strategies for Management:
Riparian areas are transitional between terrestrial and aquatic ecosystems and are
distinguished by gradients in biophysical conditions, ecological processes, and biota.
They are areas through which surface and subsurface hydrology connect waterbodies
with their adjacent uplands. They include those portions of terrestrial ecosystems that
significantly influence exchanges of energy and matter with aquatic ecosystems (i.e.,
a zone of influence). Riparian areas are adjacent to perennial, intermittent, and
ephemeral streams, lakes, and estuarine-marine shorelines.
SURVEY METHODS
Literature Review
The following data sources were reviewed to assist with biological and jurisdictional efforts:
• U.S. Department of Agriculture Natural Resource Conservation Service (USDA 2018)
• CDFW California Natural Diversity Database (CDFW 2018)
• California Native Plant Society Inventory of Rare and Endangered Plants (CNPS 2018)
• USFWS Species Occurrence Data (USFWS 2018)
Biological Survey
An initial biological assessment was conducted by Dudek Biologist Callie Ford on November 2,
2017; during this survey, Trimble GeoXT Global Positioning System (GPS) was used to delineate
the border of the Buena Vista Lagoon to the adjacent upland habitat. Following completion of this

Biologists Shana Carey and Monique O'Conner conducted a second biological study on February
2, 2018; this study included jurisdictional delineation, vegetation mapping, and a botanical and
wildlife inventory of species occurring on site.
The vegetation communities and land covers were mapped according to Holland (1986) and
Oberbauer et al. (2008). An aerial photograph map (Google Earth 2018) with a digital overlay of
the project boundary was utilized to record vegetation and any sensitive biological resources
directly in the field. All plant species and animal species encountered during the survey were
identified and recorded directly into a field notebook. In addition to species actually detected
during the surveys, expected wildlife use of the site was evaluated by known habitat preferences
of local species and knowledge of their relative distributions in the area. A compiled list of the
plant and animal species detected on site during the survey is attached to this letter report as
Appendix A and Appendix B, respectively.
The jurisdictional delineation of waters of the United States, including wetlands, under the
jurisdiction of the ACOE, CDFW, RWQCB, and county was conducted in accordance with the
1987 U.S. Army Corps of Engineers Wetland Delineation Manual (TR Y-87-1) (ACOE 1987) and
the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West
Region (Version 2.0) (ACOE 2008). Data were recorded directly onto the Wetland Determination
Data Form -Arid West Region (Appendix C), and a Timble GeoXT GPS was used to document
the location of data stations (Figure 3).
SURVEY RESULTS
The site currently includes a small commercial building and paved parking lot in the southern and
eastern portion. The northern and western portion consists primarily of disturbed habitat composed
of ornamental and non-native plant species; the northern portion of the site has a north-facing slope
that intersects the edge of Buena Vista Lagoon at the base of the slope.
Flora
The site is composed entirely of non-native vegetation, with the exception of one native species
within Buena Vista lagoon: broadleaf cattail (Typha latifolia). The site does not provide good
quality habitat for native plant species; a total of 19 plants were identified on site, of which 1 was
native (5%), and 18 were non-native (95%). The most common non-native plants identified include
Bermuda buttercup ( Oxalis pes-caprae ), myoporum (Myoporum laetum ), and Brazilian peppertree
(Schinus terebinthifolius). Using the recognized San Diego County vegetation mapping systems
(Holland 1986; Oberbauer et al. 2008), the site consists of coastal and valley freshwater marsh,
developed/urban, and disturbed habitat (Figure 3). The acreages of the vegetation communities

and land covers are listed in Table 1, and mitigation ratios are based on the City's HMP and
Biology Guidelines. On-site vegetation and land cover mapping is defined and described as
follows.

Coastal and Valley Freshwater Marsh (FM) is a habitat type that develops where the water
table is at or just above the ground surface such as around the margins of lakes, ponds, slow-
moving streams, ditches, and seepages (Holland 1986; Oberbauer et al. 2008). The portion of
Buena Vista Lagoon extending into the site at the northwestern edge was classified as a
freshwater marsh community, dominated almost entirely by broadleaf cattail, with some
encroaching myoporum.
Urban/Developed (DEV) is land that is currently developed or on which construction is currently
underway. Whether the structures are permanent, semi-permanent, pavement, hardscape, or
irrigated landscape, the land no longer has the ability to support native vegetation due to the extent
of its physical modifications (Holland 1986; Oberbauer et al. 2008). On site, urban/developed land
occurs in the southeastern portion, where a small commercial building, paved parking lot, and
adjacent ornamental plantings exist.
Disturbed Habitat (DH) is a land cover type that is characterized by a predominance of non-
native species, often introduced and established through human action. Disturbed habitat has been
physically disturbed and is no longer recognizable as native or naturalized vegetation, while
retaining a soil substrate (Holland 1986; Oberbauer et al. 2008). On site, disturbed habitat occurs
in the northwestern portion between the existing structures and the lagoon, and is dominated by
Bermuda buttercup, Brazilian peppertree, jade plant (Crassula ovata), Canary Island date palm
(Phoenix canariensis), and cape honeysuckle (Tecoma capensis).
Fauna
Due to the predominance of non-native vegetation and site disturbance characteristics, the site has
limited potential to provide habitat that supports wildlife species. The project site is mostly
DUDEK 14
10746
January 2019
Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
surrounded by existing development that has no connectivity to habitat areas, with the exception
of the northwest corner, which connects to the Buena Vista Lagoon freshwater marsh.
Furthermore, given the residential and commercial surroundings, the site is unlikely to serve as a
wildlife corridor. Several non-native trees exist within the project site; however, they are small,
and it is unlikely that special-status birds (including raptors) would use the site for nesting. There
are no prominent rocks, boulders, or features on site that could be used by special-status reptiles.
The few wildlife species detected during the survey are listed in Appendix B of this letter report.
Four wildlife species were identified on site: Anna's hummingbird (Calypte anna), bushtit
(Psaltriparus minimus), western gull (Larus occidentalis), and song sparrow (Melospiza melodia).
Jurisdictional Wetland Resources
Hydrology, vegetation, and soils were examined at two geographically distinct sampling locations,
and results were recorded on wetland determination data forms to determine the presence or
absence of wetland field indicators. The overall area was assessed for evidence of an ordinary high
water mark, hydrology indicators, wetland vegetation, and nexus to TNWs of the United States.
The extent of wetland features was determined in the field by collecting data using a GPS unit;
these shapes were transferred to topographic base, and a geographic information system (GIS)
coverage was created.
The 0.01 acres of freshwater marsh is considered a wetland under the jurisdiction of the ACOE,
RWQCB, CDFW, and the CCC. The extent of the freshwater marsh was determined based on
the presence of all three wetland indicators from the ACOE delineation manual-hydrology,
hydrophytic vegetation, and hydric soils. Figure 3 shows the data station locations, and Appendix
C includes the data station forms. Hydrophytic vegetation classifications follow Lichvar et al.
2016.
Special-Status Species
Special-Status Plants
No special-status plant species considered endangered, rare, or threatened under the CEQA
Guidelines (14 CCR 15380) were identified during the site visits. Special-status plants known to
occur in the area are described in Appendix D; however, based on the disturbed habitat and highly
urbanized area, as well as elevation and soils, no special-status plants are expected to occur on site.
One wetland species, southwestern spiny rush (Juncus acutus ssp. leopoldii), has potential to occur
in the lagoon; however, it was not observed on site.

Special-Status Wildlife
No special-status wildlife species were detected during the surveys. Special-status wildlife species
known to occur in the area are described in Appendix E.
Considering the limited native habitat on site and the disturbed nature of the habitat, there are few
special-status wildlife species that have the potential to occur within the project area (Appendix
E). There is a moderate potential for eight wildlife species to occur on site during some stage of
their life cycle ( e.g., foraging, migration, or breeding). These species are associated with the
lagoon, which the project is completely avoiding.
ANTICIPATED PROJECT IMPACTS
This section addresses direct, indirect, and cumulative impacts to biological resources that would
result from implementation of the proposed project.
Direct impacts were quantified by overlaying the proposed project grading impact limits on the
biological resources map of the site. For purposes of this assessment, all biological resources in
the areas to be graded were considered directly impacted.
Indirect impacts primarily result from adverse "edge effects" as either short-term indirect impacts
related to maintenance activities or long-term, chronic indirect impacts associated with increased
noise or the introduction of invasive species due to the proximity of houses to open space areas.
During construction activities, indirect impacts may include dust and noise, which could
temporarily disrupt habitat and species vitality. However, all project work will be subject to the
typical restrictions and requirements that address erosion, runoff, and water quality, including the
federal Clean Water Act and National Pollution Discharge Elimination System.
Cumulative impacts refer to incremental individual environmental effects over the long-term
implementation of the proposed project when considered together with other impacts from other
projects in the area. These impacts taken individually may be minor, but they are considered
collectively si gnificant as they occur over a period oftime.
Direct Impacts
The impact analysis includes an overlay of the limits of grading for the project as well as the review
of the proposed site plan. Figure 3, Biological Resources Impacts, provides the illustration of the
proposed impact limits of grading area on the biological resources. Proposed impacts will result
from the construction of the proposed project development. No impacts to the wetland buffer or
native habitat will occur from project construction (Figure 4 ).

Vegetation Communities
The proposed project has been designed to concentrate development in areas that were previously
developed or that were previously graded and are mapped as disturbed habitat. Areas within the
riparian habitat of Buena Vista Lagoon as well as the riparian buffers will not be impacted except
for uses allowed within the buffers (public trail within the 25-foot public access easement) and the
proposed FMZ B-3 . The areas of previously disturbed or developed land on the project site that
are not part of construction impact footprint will be revegetated with native habitat prior to
construction, in accordance with the City HMP Coastal Policy 7-11 (B10-2).
Vegetation Impacts
Implementation of the proposed project would result in the direct and complete loss of all land covers,
in accordance with the group designations of the Carlsbad HMP, presented in detail in Table 2 and
shown in Figure 4. Approximately 0.40 acres would be impacted as a result of the proposed project
due to grading and would occur entirely within disturbed land (BI0-1) and developed areas. No direct
impacts would occur within the 100-foot wetland buffer (Figure 4). The function of the wetland buffer
as protection for the existing native habitat will be implemented by the proposed installation of fencing
and signage to protect the habitat and preclude human access (BI0-4). The details of each impact type,
including impacts to existing riparian and upland buffers, are presented and described below.

Special-Status Plants
Special-status plant species were not detected during surveys; and a full list of species present
was prepared (Appendix D). Species with moderate potential to occur would have been
observed during the visits to the site. Additionally, impacts are not anticipated to occur in the
habitat where the potentially present riparian species would occur. Therefore, no impacts to
special status plants are anticipated.
DUDEK 17

Subject: Biology Letter Report for 5 70-580 Laguna Drive, City of Carlsbad, California
Special-Status Wildlife Species
Special-status wildlife species were not detected during surveys; and a full list of species
present was prepared (Appendix E). The only special-status wildlife species determined to have
a moderate to high potential to occur on the project was the two-striped garter snake (Thamnophis
hammondii). The following species are HMP covered species: California gnatcatcher, Cooper's
hawk, least Bell 's vireo, Southern California rufous-crowned sparrow, yellow-breasted chat. Since
the proposed impacts to the site are limited to previously disturbed or developed land covers and
there would be no impacts within the 100-foot wetland buffer, no impacts to special status species
are anticipated.
Indirect Impacts
The project site is bordered by development to the east and west, Laguna Drive to the south, and
Carlsbad HMP hardline preserve (Buena Vista Lagoon) to the north and northwest. As previously
discussed, the project proposes to incorporate a wetland buffer along the northern border into the
Carlsbad HMP Preserve (Figure 3). The proposed project would include open space adjacent to
the preserve to the north as well as a 25-foot proposed public access easement (Figure 4).
Therefore, edge effects could potentially occur along the development-preservation interface to
the north.
The preserve edge is proposed to be provided protection by signage and/or fencing. All
landscaping adjacent to the preserve is proposed to be native. There will be no lighting within the
preserve.
Indirect impacts are addressed in the HMP by compliance with the Adjacency Standards or by
avoidance of impacts to nesting birds. The HMP adjacency standards only apply to areas directly
adjacent to the preserve which include the northern and northwestern boundaries.
Vegetation Communities
Indirect impacts to vegetation communities would primarily result from adverse "edge effects."
During construction of the proposed project, edge effects may include dust, which could disrupt
plant vitality in the short term, and/or construction-related soil erosion and runoff. However,
typical construction practices, including dust control, erosion control, and water quality protection
measures, will be implemented to reduce these effects (B10-4).
Potential long-term indirect impacts on vegetation could include trampling by humans traveling
off trail, invasion by exotic plants and animals, exposure to urban pollutants (fertilizers, pesticides,
herbicides, and other hazardous materials), increase or decrease in natural fire regime, soil erosion,
DUDEK 18
10746

Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
and hydrologic changes (e.g., surface and groundwater level and quality). Although the project is
designed to minimize preserve edge effects, long-term indirect impacts could occur. Long-term
indirect impacts are anticipated to be reduced to vegetation communities because the proposed
open space, which includes the wetland habitat and the area within the 100-foot wetland buffer
including the revegetated native habitat, will be preserved. For the existing HMP Preserve off site
to the north, indirect impacts are proposed to be prevented by adherence to the Adjacency
Standards (B10-5) and the fencing that exists or is proposed. Finally, vegetation within the open
space wetland buffer will be protected by the planting of native plant species, in accordance with
the HMP Coastal Zone Standards Section 7-11 (B10-2). Implementation of these measures are
expected to reduce indirect impacts to vegetation communities to a level below significant.
Special-Status Plants
Most of the indirect impacts to vegetation communities cited previously can also affect special-
status plants. It should be noted that no special status plants were detected on site and none are
anticipated; however, if there are plants that occur off site within adjacent areas, these standard
measures provide protection. During construction of the proposed project, indirect effects may
include dust which could disrupt plant vitality in the short term and/or construction-related soil
erosion and drainage runoff. However, it is assumed that typical construction practices,
including dust and erosion control and water quality BMPs, will be implemented and will
reduce these effects. Implementation of appropriate mitigation measures (B10-4) and adherence
to the adjacency standards addressed in the Carlsbad HMP (B10-5) are expected to reduce
indirect impacts to special-status plants to a level below significant.
Special-Status Wildlife
Most of the indirect impacts to vegetation communities mentioned previously can also affect
special-status wildlife in adjacent undeveloped areas. In addition, wildlife may be indirectly
affected in the short term and long term by noise, which can disrupt normal activities. Also, adverse
indirect impacts to vegetation communities, such as trampling of vegetation, can cause degradation
of habitat quality. Implementation of appropriate mitigation measures (B10-4) and adherence to
the adjacency standards addressed in the Carlsbad HMP (B10-5) is expected to reduce indirect
impacts to special-status wildlife to a level below significant.
Indirect impacts include potential disruption of breeding birds, including potentially occurring
special-status species and other wildlife species that may use the riparian habitat for nesting.
Indirect impacts from construction-related noise may occur to special-status wildlife if construction
occurs during the breeding season (February 15 through August 31 for most species, and January 1
DUDEK 19
10746
January 2019
Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
through August 31 for raptors. However, with implementation of mitigation measures to protection
indirect impacts to nesting birds (B10-3), the impacts will be less than significant.
Long-term adverse impacts to wildlife, such as predation by urban pest species (e.g., American
crows (Corvus brachyrhynchos), raccoons, striped skunks) and human presence, would likely
occur despite the design of a consolidated preserve.
MITIGATION MEASURES
The following land cover is not considered sensitive and does not require mitigation:
urban/developed. However, disturbed habitat will require mitigation in the form of an in-lieu
mitigation fee to fund the acquisition of the MHCP core area.
A number of mitigation measures or conditions are required in order to protect nesting birds and
special-status species from direct and indirect impacts. Mitigation measures are provided for direct
and indirect impacts as summarized below.
Mitigation for Direct Impacts
Mitigation Fee
Vegetation communities or land covers that do not require mitigation or that are not proposed to
be impacted are not included.
B10-1 Mitigation requirements for permanent impacts are set forth in the Carlsbad HMP
and mitigation fee will be paid for impacts to disturbed habitat in accordance with
these requirements.
Mitigation for Indirect Impacts
On-Site Restoration
Areas proposed to be restored within the 100-foot wetland buffer, in accordance with the City's
HMP Coastal Policy 7-11, are currently urban developed land or disturbed habitat dominated by
non-native invasive species. The areas are in direct proximity to existing native habitat and will be
highly suitable for restoration to native habitat. It is envisioned that the restoration area can be
restored to native habitat within the year and may require monitoring for the standard 5-year
period.

Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
the City and/or Agencies for review at least 30 days prior to initiating project
impacts. The HMMP and Restoration Landscape Plan shall be prepared and
implemented consistent with MHCP Volume II, Appendix C (Revegetation
Guidelines), and Vol. III; HMP pp. F-8 to F-11; and Open Space Management Plan
Sec. 3.1.5. The HMMP should, at a minimum, include an evaluation of restoration
suitability specific to proposed habitat types, soil and plant material
salvage/translocation, planting and seeding lists, discussion of irrigation,
maintenance and monitoring program, and success criteria. All areas should be
monitored for a minimum of 5 years to ensure establishment of intended plant
communities.
Restoration techniques, as specified in the HMMP, may include hydroseeding,
hand-seeding, imprinting, and soil and plant salvage. The HMMP shall also include
criteria to measure success and describe how monitoring of revegetation efforts will
be implemented.
The HMMP shall include a description of appropriate plantings within the 25-foot
public access easement and FMZ B-3. Allowable plantings include native, low fuel
species that do not require long-term irrigation.
Mitigation Measures to Avoid Indirect Impacts to Nesting Birds
B10-3
DUDEK
Clearing and grading activities should be avoided during the bird breeding season
(February 15 -September 15) to reduce indirect impacts will occur to nesting birds
that may be present within the construction footprint or restoration areas. Other
construction activities will also be avoided during the breeding season, if feasible.
If this cannot be avoided, the following measures will be taken:
• Nesting bird surveys will be conducted by a qualified biologist in appropriate
habitat for nesting raptors and migratory birds and within a 500-foot survey buffer
within three days of construction.
• If nests of listed birds, migratory birds, raptors, or other special-status species
are located, they will be fenced with a protective buffer of at least 500 feet from
active nests oflisted species, and 300 feet from other special-status bird species.
All construction activity will be prohibited within this area. Reduced buffers
can be requested from the City if the project biologist can demonstrate that the
nesting success will not be affected.

Additional Measures for Mitigating Indirect Impacts
B10-4
DUDEK
The potential for significant indirect impacts during construction should be
mitigated through implementation of the following standard measures as stated in
the City's Biology Guidelines and Grading and Landscaping Requirements.
• The footprint of disturbance shall be specified in the construction plans.
Construction limits will be delineated with orange fencing, and in areas
potentially subject to project related runoff, silt fencing will be used to delineate
the impact footprint. All fencing will be maintained until the completion of all
construction activities, at which time all fencing will be removed. All
construction personnel and associates shall be instructed that their activities,
vehicles, equipment, and construction materials are restricted to the proposed
project footprint, designated staging areas, and routes of travel. If any impacts
shall occur beyond the approved impact footprint, all work in the immediate
vicinity shall cease until the disturbance limit breach has been addressed to the
satisfaction of the City.
• The qualified project biologist shall review grading plans (e.g., all access routes
and staging areas), and monitor construction activities throughout the duration
of grading/ground disturbance associated with the project to ensure that all
practicable measures are being employed to avoid incidental disturbance of
habitat and any target species of concern outside the project footprint.
• Any habitat that is impacted that is not in the identified project footprint shall
be disclosed immediately to the City, USFWS, CDFW, and CCC and shall be
compensated at a minimum ratio of 5: 1.
• Construction employees will limit their activities, vehicles, equipment, and
construction materials to the fenced project footprint.
• Equipment storage, fueling, and staging areas shall be located on disturbed
upland sites with minimal risk of direct drainage into riparian areas or other
sensitive habitats, and at least 100 feet from waters of the United States. These
designated areas shall be located in such a manner as to prevent any runoff from
entering sensitive habitat. All necessary precautions shall be taken to prevent
the release of cement or other toxic substances into surface waters. All project-
related spills of hazardous materials shall be reported to the City and shall be
22
10746

DUDEK
cleaned up immediately and contaminated soils removed to approved disposal
areas.
• Lighting in or adjacent to the preserve will not be used, except where essential for
roadway, facility use, and safety. If nighttime construction lights are necessary, all
lighting adjacent to natural habitat will be shielded and/or directed away from
habitat.
• Fugitive dust will be avoided and minimized through watering and other
appropriate measures.
• Exotic species that prey upon or displace target species of concern should be
permanently removed from the site.
• To avoid attracting predators of the native wildlife species, the project site
shall be kept as clean of debris as possible. All food related trash items shall
be enclosed in sealed containers and regularly removed from the site(s). Pets
of project personnel shall not be allowed on site where they may come into
contact with any native species.
• The City of Carlsbad has the right to access and inspect any sites of approved
projects including any restoration/enhancement area for compliance with
project approval conditions including these BMPs. The USFWS and CDFW
may accompany City representatives on this inspection.
• Grading activity shall be prohibited during the rainy season: from October 1st
through April 1st of each year.
• All graded areas shall be landscaped prior to October 1st of each year with either
temporary or permanent landscaping materials, to reduce erosion potential.
Such landscaping shall be maintained and replanted if not well-established by
December 1st following the initial planting.
• The October 1st grading season deadline may be extended with the approval of
the City Engineer subject to implementation by October 1st of special erosion
control measures designed to prohibit discharge of sediments off-site during
and after the grading operation. Extensions beyond November 15th may be
allowed in areas of very low risk of impact to sensitive coastal resources and
may be approved either as part of the original coastal development permit or as
an amendment to an existing coastal development permit.
23
10746

Mr. Farrow
Subject: Biology Letter Report for 570-580 Laguna Drive, City of Carlsbad, California
• If any of the responsible resource agencies prohibit grading operations during
the summer grading period in order to protect endangered or rare species or
sensitive environmental resources, then grading activities may be allowed
during the winter by a coastal development permit or permit amendment,
provided that appropriate best management practices are adopted.
Adjacency Standards
B10-5
DUDEK
In order to prevent impacts of the proposed development on the HMP preserve area off
site and to the north and northwest of the project site, the proposed project would
comply with the adjacency standards outlined in the Carlsbad HMP.
Fire Management
Existing non-native plants will be removed and replaced with native species. This
will reduce the risk from fire through reduction in adjacent fuel loads. A FMZ B-3
will be established from the structures outward and shall be maintained to be clear
of dead and dying combustible material.
Erosion Control
Erosion control, for some areas of the City, is needed where there are erodible soils,
steep slopes, soils with low water-holding capacity, sparse to no vegetation, and
hydrologic soil conditions. Standard BMPs will be implemented to slow surface flow
and dampen initial precipitation flow in the development area. In addition, no new
surface drainage is proposed to be directed into the open space areas.
Landscaping Restrictions
Landscape practices may be of concern where landscaping is in conflict with the
management and maintenance of undeveloped areas. Landscape planting palettes
for the proposed project will prohibit non-native, invasive plant species in the areas
adjacent to the riparian or upland habitat or adjacent to the HMP preserve off site
to the north or northwest. In addition, because the site is within the Coastal Zone,
no invasive plant species will be used in the landscaping of the development. These
plant species are identified in the Carlsbad HMP but the list of invasive species that
will be avoided is not limited to the species on the Carlsbad HMP list. Irrigation of
the landscaping will be designed and scheduled to avoid runoff into the proposed
open space. This will also prevent movement of fertilizer and pesticides into the

SUMMARY
open space area. The wetland buffer will be restored with native habitat (refer to
B10-2).
Fencing, Signs, and Lighting
To prevent entry into the riparian habitat (open space area protected by the
restrictive covenant) by people and pets, the area will be fenced in accordance with
requirements of the City and resource agencies and as appropriate. Signs will be
attached to the fence at intermittent intervals to alert the residents of the sensitive
nature of the open space area. A trail is proposed to be located within the 15 feet
closest to development and the fencing will preclude people from passing beyond
the trail into the habitat. No lighting is proposed for the areas adjacent to the HMP
preserve or the riparian habitat. Lighting that may potentially intrude into the
riparian habitat will be shielded or directed away from the open space area.
Predator and Exotic Species Control
Similar to the issue for landscaping described previously, there are concerns
related to non-native species when native areas are adjacent to development areas.
The property owner of the proposed development will alert the residents to the
potential effects that domestic animals may have on the native fauna and flora.
The riparian habitat will be fenced to discourage the entry of domestic animals
into the open space.
The majority of the project site consists of developed areas and disturbed habitat. There is a clear
distinction between the lagoon and the upland slopes. The dense cattail marsh area in the northwest
corner of the parcel remains an undisturbed and functional part of the Buena Vista Lagoon. This
portion of the project site has potential to support wildlife species, including special-status species
that are associated with the overall lagoon habitat. However, based on the steep slopes and highly
disturbed area between the lagoon and the existing developed areas, the potential for species to
occur outside of the lagoon is low. The proposed project is located outside of the lagoon and
associated 100-foot buffer. The wetland buffer will be restored with native plants. All direct and
indirect impacts are reduced through implementation of mitigation measures.
