ROMERIA STREET DRAINAGE IMPROVEMENTS
CITY OF CARLSBAD, CALIFORNIA
INTRODUCTION
The City of Carlsbad (City) proposes to remove and replace an existing concrete-lined channel
( channel), splash wall, headwall, and two brow ditches, and to install new slope protection in order to
ensure the channel functions adequately for flood control. The project is necessary to complete the
Master Drainage and Storm Water Quality Management Plan and is a covered project as listed in
Appendix B of the City of Carlsbad Habitat Management Plan (HMP). The project takes place on a
drainage easement on City-owned property. Additionally, the City will install an all-weather,
permanent maintenance access ramp and pad to replace the current access from Levante Street. The
project study area addressed in this report includes 360 linear feet of concrete channel, 130 feet of
brow ditch and a buffer of surrounding habitat approximately 200 feet west of the concrete-lined
channel that extends to the boundaries of the adjacent properties on the east side of the concrete-lined
channel. This analysis addresses the area upstream of the culvert under La Costa Avenue (Figure 1).
This report has been prepared pursuant to the California Environmental Quality Act (CEQA) and
addresses the requirements of the Federal Endangered Species Act (FESA) of 1973, the Federal Clean
Water Act (CWA), the California Fish and Game Code, the California Endangered Species Act
(CESA), and the HMP. This report has been prepared for use by the United States Army Corps of
Engineers (Corps), the Regional Water Quality Control Board (RWQCB), the California Department
of Fish and Game (CDFG), and the United States Fish and Wildlife Service (USFWS) as part of their
review of applications for permit authorization.
All biological surveys referenced in this report were conducted under contract to the City by LSA
Associates, Inc. (LSA). The findings and conclusions presented in this report, including the location
and extent of wetlands and other waters subject to regulatory jurisdiction, represent the professional
opinion ofLSA. These findings and conclusions should be considered preliminary until verified by
the appropriate regulatory agencies.
SITE DESCRIPTION AND HISTORY
The project is located near the intersection of La Costa Avenue and Romeria Street in the City of
Carlsbad, San Diego County, California, on the United States Geological Survey (USGS) Rancho
Santa Fe, California 7.5-minute topographical quadrangle map (Figure 1). Specifically, the project
is located in Section 36, Township 12 South, Range 4 West, SBBM. The project study area is located
in a natural low point with an elevation of 115 feet above mean sea level (AMSL) at the upstream
end to approximately 90 feet AMSL at the downstream end. Flows are conveyed in a concrete-lined
swale in a northerly direction. The surrounding area consists of residential development. The project
is bounded vacant lots, residential development, and Romeria Street to the east, La Costa A venue to
the north, and vacant lands and residential development to the west and south. A reinforced concrete
pipe (RCP) culvert with a 48-inch-diameter pipe conveys storm flows from the concrete drainage
under La Costa Avenue, where the drainage continues north approximately 850 feet and outlets into
San Marcos Creek (Rick Engineering 2007). The majority of the project study area is located within a
drainage easement on land owned by the City. The project is contained within a Hardline Preserve
according to the HMP (Figure 2). The channel has been subject to undermining and has deteriorated
since construction in 1972. Several portions of concrete lining are missing or severely damaged.

PROPOSED PROJECT
The City proposes to remove and replace the existing channel, splash wall, headwall, and two brow
ditches, and to install new slope protection in order to ensure the channel provides adequate flood
control for public safety and welfare. Construction and future maintenance access will be provided by
grading an all-weather access ramp and pad from La Costa A venue to the channel. Current
maintenance access is from Levante Street, approximately 1,050 feet from the culvert and is not
functional during wet weather conditions. Installation of an all-weather access road is a health, safety,
and welfare requirement of the City to protect La Costa Avenue from flooding. The project was
designed to minimize impacts to biological resources but is constrained by existing factors such as
topography, location relative to existing roads, and need for permanent maintenance access. The
project takes place on a drainage easement on City-owned property. Two test pit locations for
geological testing are proposed adjacent to the west bank of the channel (Appendix A) in the location
of the access road.
REGULATORY SETTING
United States Army Corps of Engineers
Pursuant to §404 of the CWA, the Corps regulates discharges of dredged or fill material into waters
of the United States. These waters include wetlands and nonwetland bodies of water that meet
specific criteria, as outlined in the guidelines provided in the Corps 1987 Manual and founded on a
connection, or nexus, between the water body in question and interstate commerce. The following
definition of waters of the United States is taken from the discussion provided at 33 CFR 328.3: .
The term waters of the United States means:
(1) All waters which are currently used, or were used in the past, or may be susceptible to use
in interstate or foreign commerce ... ;
(2) All interstate waters including interstate wetlands;
(3) All other waters such as intrastate lakes, rivers, streams (including intermittent streams)
... the use, degradation or destruction of which could affect interstate or foreign
commerce ... ;
( 4) All impoundments of waters otherwise defined as waters of the United States under the
definition; and
(5) Tributaries of waters defined in paragraphs (a) (1)-(4) of this section.
The Corps and Environmental Protection Agency define wetlands as follows:
"Those areas that are inundated or saturated by surface or groundwater at a frequency
and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted to life in saturated soil conditions."
In order to be considered a jurisdictional wetland under Section 404, an area must possess three
wetland characteristics: hydrophytic vegetation, hydric soils, and wetland hydrology. Each
characteristic has a specific set of mandatory criteria.

In 2006, the United States Supreme Court further considered the Corps jurisdiction of "waters of the
United States" in the consolidated cases Rapanos v. United States and Carabell v. United States
(i26 S. Ct. 2208), collectively referred to as Rapanos. The Supreme Court concluded that wetlands
are "waters of the United States" if they significantly affect the chemical, physical, and biological
integrity of other covered waters more readily understood as navigable. On June 5, 2007, the Corps
issued guidance regarding the Rapanos decision. This guidance states that the Corps will continue to
assert jurisdiction over traditional navigable waters, wetlands adjacent to traditional navigable waters,
relatively permanent nonnavigable tributaries that have a continuous flow at least seasonally
(typically three months), and wetlands that directly abut relatively permanent tributaries. The Corps
also will determine jurisdiction over waters that are not relatively permanent, nonnavigable
tributaries, and over wetlands adjacent to nonnavigable tributaries that are not relatively permanent
only after making a significant nexus finding.
Furthermore, the preamble to Corps regulations (Preamble Section 328.3, Definitions) states that the
Corps does not generally consider the following waters to be waters of the United States. However,
the Corps reserves the right to regulate these waters on a case-by-case basis:
• Nontidal drainage and irrigation ditches excavated on dry land
• Artificially irrigated areas that would revert to upland if the irrigation ceased
• Artificial lakes or ponds created by excavating and/or diking dry land to collect and retain water
and used exclusively for such purposes as stock watering, irrigation, settling basins, or rice
growing
• Artificial reflecting or swimming pools or other small ornamental bodies of water created by
excavating and/or diking dry land to retain water for primarily aesthetic reasons
• Water-filled depressions created in dry land incidental to construction activity and pits excavated
in dry land for purposes of obtaining fill, sand, or gravel unless and until the construction or
excavation operation is abandoned and the resulting body of water meets the definition of waters
of the United States
Often, waters found to be isolated and not subject to CW A regulation still are regulated by the
RWQCB under the State Porter-Cologne Water Quality Control Act (Porter-Cologne Act).
Regional Water Quality Control Board
The R WQCB has regulatory authority over waters of the United States pursuant to CW A §401 and
waters of the State pursuant to the Porter-Cologne Act. The Corps cannot issue authorization for fill
or discharge into waters of the United States without a Certification of Water Quality from the
RWQCB. Additionally, isolated nonnavigable waters and wetlands excluded from Corps jurisdiction
are subject to RWQCB authority as waters of the State, and any discharge of waste (RWQCB
considers fill to be waste) may require a Report of Waste Discharge and may be subject to Waste
Discharge Requirements by the RWQCB.

The RWQCB can require mitigation measures beyond those required by the Corps or CDFG.
Typically, however, the mitigation proposed to satisfy the Corps and CDFG meets RWQCB
requirements to offset impacts to water quality.
United States Fish and Wildlife Service
The FESA sets forth a two-tiered classification scheme based on the biological health of a species.
Endangered species are those in danger of becoming extinct throughout all or a significant portion of
their range. Threatened species are those likely to become endangered in the near future; Special
Rules under Section 4(d) can be made to address threatened species. Ultimately, the FESA attempts to
bring populations of listed species to healthy levels so that they no longer need special protection.
Section 9 of the FESA prohibits the "take" of listed species by anyone unless authorized by the
USFWS. "Take" is defined as "conduct which attempts or results in the killing, harming, or harassing
of a listed species." "Harm" is defined as "significant habitat modification or degradation where it
actually kills or injures wildlife by significantly impairing essential behavior patterns, including
breeding, feeding, or sheltering." "Harass" is defined as an "intentional or negligent act or omission
which creates the likelihood of injury to wildlife by annoying it to such an extent as to significantly
disrupt normal behavioral patterns, including breeding, feeding, or sheltering." Therefore, in order to
comply with the FESA, any proposed project should be assessed prior to construction to determine
whether the project will impact listed species or, in the case of a federal action on the project,
designated critical habitats. If no federal action is associated with the proposed project, and the
project will result in take of listed species, authorization from the USFWS in the form of a Section
I0(a) take permit and an accompanying HCP is required. If a federal action exists and the project may
impact listed species or designated critical habitat, then pursuant to Section 7 of the FESA,
consultation with the USFWS is required. That consultation can result in an incidental take
authorization through a Biological Opinion.
California Department of Fish and Game
• Section 1602 of the California Fish and Game Code empowers CDFG to issue agreements for any
alteration of a river, stream, or lake where fish or wildlife resources may be adversely affected.
Streams ( and rivers) are defined by the presence of a channel bed and banks and at least an
intermittent flow of water.
CDFG regulates wetland areas only to the extent that those wetlands are part of a river, stream, or
lake as defined by CDFG. While seasonal ponds may be subject to CDFG jurisdiction, if they are not
associated with a river, stream, or lake, they are not subject to jurisdiction of CDFG under Section
1602 of the Fish and Game Code.
The CESA State Fish and Game Code (§§2050-2098) was signed into law in 1984. Intended to
parallel the federal law, the CESA prohibits the unauthorized "take" of species listed as threatened or
endangered under its provisions. However, a significant difference exists in the CESA definition of
"take," which is limited to actually or attempting to "hunt, pursue, capture, or kill." CESA provisions
for authorization of incidental take include consultation with a State agency, board, or commission
that is also a State Lead Agency pursuant to CEQA; authorization of other entities through a 2081

permit; or adoption of a federal incidental take authorization pursuant to §2081.1. Similar to the
federal act, actions in compliance with the measures specified in the consultation process or 2081
permit are not prohibited.
Nesting Birds
The Migratory Bird Treaty Act (MBTA) regulations and portions of the California Fish and Game
Code prohibit the "take" of nearly all native bird species and their nests. While these laws and
regulations originally were intended to control the intentional take of birds and/or their eggs and nests
by collectors, falconers, etc., they can be applied to unintentional take (e.g., destroying an active nest
by cutting down a tree). It is sometimes possible to obtain a permit for relocating or removing a nest.
City of Carlsbad Zoning Ordinance 21.210.040 prohibits clearing or grubbing of vegetation during
wildlife breeding seasons. This includes birds and raptors. According to this ordinance, all
construction activities are prohibited within 300 feet of an active nest or territory of a listed species.
City of Carlsbad Habitat Management Plan
The City HMP is a citywide, comprehensive program that provides for coordination with the resource
agencies to preserve and protect special-status biological resources and habitats while allowing for
development within the City consistent with the General Plan and Growth Management Plan. The
HMP provides for the take of special-status species incidental to the implementation of private and
public projects consistent with the HMP. These permits are issued under the PESA, the CESA, and
the California Natural Community Conservation Planning Act. The City's Growth Management Plan
divided the City into 25 Local Facilities Management Zones (LFMZ) for planning purposes. The
project site is located within LFMZ 6. The project area is also located within an Existing Hardline
Preserve Area, as shown in Figure 2. It is not located within any Focused Planning Areas (FPA),
Standards Areas, Proposed Hardline Areas, or Exempted Areas. The HMP includes goals and policies
as guidelines for development and conservation efforts within the City. The HMP assigns values and
mitigation ratios for habitat groups and types that occur within the City.
Development located within an Existing Hardline Preserve Area is prohibited. However, exceptions
may be processed as minor or major amendments. Additionally, some management activities may be
consistent with the HMP, such as hydrology and flood control, as long as they do not impact habitat
or species. A minor amendment includes minor adjustments to hardline boundaries that result in no
net loss of the quality or quantity of habitat. Major amendments are required if lands are removed
from conserved areas or if a hardline boundary adjustment results in a net loss of habitat or reduction
in habitat quality (City of Carlsbad 2008). However, Appendix B of the HMP lists City projects that
are covered by the City Land Mitigation Bank (Lake Calavera mitigation parcel), which include
future drainage projects needed to complete the Master Drainage and Storm Water Quality
Management Plan. Therefore, this project may utilize the Lake Calavera mitigation parcel for impacts
to upland habitat, as needed, with the exception of wetland areas.

Natural Community Conservation Plans
fu an effort to respond to growing concern over the conservation of coastal sage scrub and other
special-status biological communities, federal, State, and local agencies have developed a
multispecies approach to habitat conservation planning known as the Natural Communities
Conservation Planning process. This was made possible by legislation (Assembly Bill 2172) that
authorized the CDFG to enter into agreements for the preparation and implementation of Natural
Communities Conservation Plans (NCCPs). The USFWS joined in this effort, utilizing both the
Section 4( d) Special Rule and the Habitat Conservation Plan (HCP) processes.
The goal of the Natural Communities Conservation Planning program is to identify significantly
important coastal sage scrub habitat and to develop ways and means to preserve and/or restore the
ecological value of this and associated plant communities and their attendant special-status species in
a rapidly urbanizing setting.
The North County Multiple-Habitat Conservation Program (MHCP) is a subregional Natural
Communities Conservation Planning effort encompassing the land of seven member cities (Carlsbad,
Encinitas, Escondido, Oceanside, San Marcos, Solana Beach, and Vista) that has not been adopted at
the time of this report preparation. The MHCP is being developed by a cooperative effort between the
seven member cities and the San Diego Association of Governments. The HMP is an important
component to the future adoption of the MHCP that is specific to the City.
SURVEY METHODS AND LIMITS
Literature Review and Records Search
Prior to conducting fieldwork, LSA biologists conducted a literature review and database records
search on February 21, 2008, to identify the existence or potential occurrence of special-status
biological resources (e.g., plant and animal species) in or within the vicinity of the project study area.
LSA conducted record searches in the California Natural Diversity Database (CNDDB) and
California Native Plant Society's (CNPS) electronic databases for species expected to occur within
the vicinity of the project study area. Current electronic database records reviewed by LSA included
the following:
• CNDDB information (i.e., RareFind 3.1.0), administered by the CDFG. This database covers lists
of special-status animal and plant species, as well as sensitive natural communities that occur
within California.
• CNPS Electronic Inventory of Rare and Endangered Vascular Plants of California (Skinner and
Pavlik 1994), which identifies four specific designations or "Lists" of special-status plant species
and summarizes regulations that provide for the conservation of special-status plants (see Table A
below). The following quote is excerpted from the CNPS Inventory section that deals with CEQA
and special-status plant conservation:

"The CDFG recognizes that Lists lA, lB, and 2 of the CNPS Inventory consist of
plants that, in a majority of cases, would qualify for listing [pursuant to CEQA
Guidelines Section 15380], and the Department recommends they be addressed in
Environmental Impact Reports (EIR)."
In addition to these resources, other sensitive species known by LSA to occur in the general area also
were considered.
General Reconnaissance Survey and Vegetation Mapping
Field maps of the areas to be surveyed were prepared, including a 2007 aerial photograph base
overlaid with project-level topographic data and preliminary project boundaries at a scale of 1 inch=
225 feet. These field maps were used for all subsequent surveys. LSA Biologist Brianna Wood and
Principal Biologist Mike Trotta conducted a general reconnaissance survey of the site on February 25,
2008, to generally assess the existing habitat, identify potentially suitable habitat for special-status
species, and determine whether focused surveys for special-status species are warranted. Mike Trotta
conducted an additional follow-up site visit on March 4, 2008, to assess additional areas proposed for
impacts that were not previously surveyed. Vegetation communities on site were recorded on field
maps and digitized using Geographic Information Systems (GIS) software. These communities were
classified according to the HMP vegetation descriptions. Species-specific focused surveys were not
conducted due to lack of suitable habitat on site to warrant such surveys. The results of general
reconnaissance surveys are discussed further below.
Jurisdictional Delineation
LSA Delineation. LSA evaluated all areas of potential jurisdiction within the project study area
according to the 1987 Manual, Regional Supplement, and CDFG code. Channel width measurements
between the ordinary high water mark (OHWM) (Corps jurisdiction) and streambed banks (CDFG
jurisdiction) were recorded along drainage channels on site. Additionally, the limits of riparian
vegetation (CDFG jurisdiction), although recently pruned, were recorded adjacent to the drainage.
LSA biologists Dan Rosie and Brianna Wood conducted a routine wetland determination survey on
February 26, 2008. Using a 2007 aerial photograph base at a scale of 1 inch= 225 feet, they prepared
field maps of the area to be surveyed. They surveyed the project study area on foot in order to identify

and map potential jurisdictional areas and evaluate them according to Corps and CDFG criteria. Data
were recorded directly on the field maps. The only areas to be affected by the proposed project were
evaluated. Findings are reported in the Jurisdictional Delineation Report (LSA 2008). Potential
jurisdictional areas were evaluated according to the following criteria.
Areas supporting species of plant life potentially indicative of wetlands were evaluated according to
routine wetland delineation procedures described in the Regional Supplement. Representative sample
points were selected and examined in the field in those areas where wetland jurisdiction was in
question or needed to be confirmed. At each sample point, the dominant and subdominant plant
species were identified, and their wetland indicator status was noted (Reed 1988). A small sample pit
(approximately 12 to 20 inches deep) was dug at each point in order to examine soil characteristics
and composition. Soil matrix colors were classified according to the Munsell Soil Color Charts
(Munsell Color 2000). Hydrological conditions, including any surface inundation, saturated soils,
groundwater levels, and/or other wetland hydrology indicators, were recorded. General site
characteristics also were noted. Standard data forms were completed for the observation plots and are
included as an appendix to the Jurisdictional Delineation Report (LSA 2008). Photographs of the
sample pit locations are also included as an appendix to the Jurisdictional Delineation Report
(LSA 2008).
Based on these field measurements, the boundaries of the potential jurisdictional areas were mapped
on an orthographically rectified aerial photograph of the subject area. The lengths of drainages within
the project site were determined using GIS software.
RESULTS
Vegetation Mapping
Five vegetation communities and the concrete-lined channel were identified and recorded within the

Developed (Concrete-Lined Channel). The channel width is approximately 8.5 feet and extends
approximately 360 feet from culvert to culvert. Perennial flows, presumably from urban runoff are
conveyed generally from south to north, where they eventually end up in San Marcos Creek.
The OHWM averages approximately one (1) foot in width. The channel is concrete-lined throughout
the entire length; however, portions of the concrete lining are missing or severely degraded. Sediment
has built up in portions of the channel that support vegetation dominated by cattails (Typha sp.) and
ripgut brome (Bromus diandrus).
Coastal Sage Scrub. Coastal sage scrub occurs along the northern edge of the project site, west of the
culvert inlet. This type of coastal sage scrub can be further defined as Diegan coastal sage scrub,
which is considered a special-status habitat under California regulations and policies. It is given the
highest inventory priority in the CNDDB (City of Carlsbad 1999). In the project study area, this
community is composed primarily of California sagebrush (Artemisia californica), coyote bush
(Baccharis pilularis), California buckwheat (Eriogonumfasciculatum), and California adolphia
(Adolphia californica) (CNPS 2), deer weed (Lotus scoparius), and coast goldenbush (Jsocoma
menziesii).
Disturbed Habitat. This designation applies to areas that have been repeatedly disturbed by human
activity and have been left as bare ground (access roads) or have been colonized by nonnative plants.
This classification is not included in the HMP classification scheme. Common plant species in these
areas include tocalote (Centaurea melitensis), mustard (Brassica sp.), clover ( Oxalis sp.), Hottentot
fig (Carpobrotus edulis), and Russian thistle (Salsola tragus). Disturbed habitat occurs scattered
throughout the project study area, but is concentrated on the western side of the channel at the
southern terminus (upstream end) parallel to the channel. At present, this area is the maintenance
access road.
Disturbed Wetlands. Disturbed wetlands are not considered a native plant community. This habitat
typically occurs where the natural wetland vegetation has been degraded by mechanical activities or
invaded by weedy, nonnative species. This habitat is characterized by open and patchy vegetation that
includes both native and introduced species (City of Carlsbad 1999). The disturbed wetlands within
the project study area occur on the western side of and directly adjacent to the channel. The area
appears to be perennially saturated due to seepage from the adjacent slope and is characterized by
heavy clay soils. Dominant species include tamarisk (Tamarix sp.) and cattails (Typha sp.); however,
vegetation in this area has been pruned recently. This area historically served as maintenance access
to a drainage channel.
Nonnative Grassland. This designation applies to grassland dominated by introduced Mediterranean
grasses in portions of the project study area that have been cleared or otherwise disturbed by human
maintenance activities for fire prevention. These areas exist on the upper slope on the western portion
of the project study area, as well as a strip along the entire eastern boundary of the project study area.
The nonnative grasslands also include some floral components of disturbed habitat, as described
above.

Native Grassland. This community is generally characterized by perennial bunch grasses. Nonnative
and introduced annuals occur between the perennials. This community generally occurs on fine-
textured (often clay) soils. This community is located on the slope of the west side of the channel
where soils have not been disturbed. The dominant species within this community include purple
needlegrass (Nase/la pulchra), blue-eyed grass (Sisyrinchium helium), bladder pod (Jsomeris
arborea), sweet fennel (Foeniculum vulgare), soap plant (Chlorogalum sp.), and bindweed
(Calystegia macrostegia).
Under California regulations and policies, native grassland is considered a special-status habitat. This
status reflects its limited distribution, potential to support sensitive plant species, use as raptor
foraging habitat, and continuing decline due to development and agricultural activities. Areas with at
least 10 percent cover of purple needlegrass or foothill needlegrass (Nassella lepida) are identified in
the CNDDB as priority areas for monitoring and restoration efforts. In the project area, the native
grassland can be further defined as valley needle grass grassland with greater than 10 percent cover of
purple needlegrass. This native habitat is extremely limited in Carlsbad (City of Carlsbad 1999).
Inventory of Plants and Wildlife
Lists of observed vascular plants and wildlife species can be found in Appendices D and E,
respectively. Observed plants are discussed in detail above and included many nonnative species as
well as components of coastal sage scrub and native grasslands. Wildlife observed in the project area
consisted mainly of commensal species known to utilize developed areas. Special-status plants and
animals are discussed below.
Special-Status Species
Special-status species include "listed species," which are termed threatened, endangered, or candidate
by the USFWS or CDFG, as well as "nonlisted species." Nonlisted special-status species include
California Species of Concern (CSC) and California Fully Protected (CFP) species, as designated by
the CDFG, as well as plant species in the HMP, and CNPS Lists 1 and 2, which include species that
are rare or endangered in California.
The CDFG maintains additional information for species with the designation of "Special Animal"
(SA) and "Special Plant" (SP). This designation does not afford specific protection for the species and
is not an indicator of rarity of the species. Additionally, the CNPS maintains List 3 (species about
which more information is needed) and List 4 (a watch list). These lists also do not afford any specific
protection or status to the species. These species are not considered special-status species, but known
and probable occurrences of SA species and observations of CNPS List 3 and List 4 species are
documented in this report for purposes of full disclosure under CEQA. Appendix B contains the
species lists collected from the literature/records review.
Appendix C provides a summary of information regarding the species identified from literature
sources and field observations during the February 2008 surveys as having a moderate or higher
potential to occur in the project vicinity. For a complete list of the special-status species that were

considered, including those with a low potential to occur, refer to Appendix B. They are addressed in
this particular analysis based on the habitat types present in the immediate project study area.
Each special-status species with the potential to be present in the project vicinity and project site is
discussed. The potential for species of special-status to occur within the project site was ranked as
absent, low, moderate, high, or present. The occurrence potential was determined using the following
criteria:
Low Existing populations are not known to occur near the site, and any potential habitat is of
marginal quality; or, the species is known to occur near the site but suitable habitat is
not present on site. This category also applies to bird species that migrate through the
project site, but would not be present during the nesting season ( or for which no
suitable nesting habitat is present), and for species with moderate potential to occur but
were not detected during focused surveys.
Moderate The species is not known to occur near the site, but suitable habitat is present within or
near the project site.
High The species is known to occur near the site, and suitable habitat occurs within the
project site.
Present The species is reported by natural resource agencies as present within the project site,
and suitable habitat is found to occur within the project site, or the species was
observed during the survey. The designation "Foraging Birds Present" indicates species
that were observed on the site, but are not expected to nest on the site.
No special-status species were observed in or near the project site with the exception of California
adolphia as noted above. California adolphia is a CNPS list 2 species as well as a CDFG SP and is a
dominant component of the coastal sage scrub community on the project site.
Special-status wildlife species with the potential to occur on site due to the presence of suitable
habitat within the project area include coastal California gnatcatcher (Polioptila californica
californica). This species relies on coastal sage scrub habitat, and 0.3 acre of coastal sage scrub is
present on site. However, the coastal sage scrub on site consists of fragmented habitat that is isolated
from larger patches of coastal sage scrub, and coastal California gnatcatchers are unlikely to utilize
the area and have not been observed. Coastal sage scrub habitat requires 2: 1 mitigation for areas
occupied by the coastal California gnatcatcher and 1: 1 for unoccupied coastal sage scrub. Raptors
may forage over the native and nonnative grassland habitat present on site; however, no raptors are
expected to nest in the project area due to lack of suitable nesting habitat. No other habitat capable of
supporting special-status species was observed in the project area. Mitigation ratios required by the
HMP for all habitat types in the project area are discussed under "Impacts" below.
Jurisdictional Delineation
Corps Section 404 Jurisdiction. Flows from the channel, which can be considered relatively
permanent water (RPW) are conveyed under La Costa A venue through a 48-inch diameter RCP
culvert where the drainage continues north for approximately 850 feet and outlets into San Marcos
Creek (Rick Engineering 2007). San Marcos Creek, also considered a RPW, carries flows west into

Batiquitos Lagoon (an RPW), which has a tidal connection with the Pacific Ocean. Because of the
direct connection to the ocean, a traditional navigable waterway, the channel itself is subject to Corps
jurisdiction as nonwetland waters of the United States. The limits of Corps jurisdiction were
determined using the OHWM of the channel.
The hydrophytic vegetation criterion for Corps jurisdictional wetlands is satisfied by a prevalence of
wetland vegetation. The areas mapped by LSA as disturbed wetland habitat are dominated by
hydrophytic vegetation, some of which has been subject to disturbances. The dominant plant species
associated with the potential wetland portions of the Romeria Street Drainage Improvement project
study area include cattails, tamarisk, and coastal goldenbush.
Two sample pits bordering the channel in areas with hydro logic indicators that were dominated by
hydrophytic vegetation produced soils with hydric indicators, thus satisfying all three criteria for
Corps jurisdictional wetlands. Under Corps guidance, agencies will assert jurisdiction over navigable
waters and their adjacent wetlands, where adjacent is defined as "bordering, contiguous, or
neighboring." Therefore, finding a surface connection is not required to determine adjacency under
this definition. Please refer to the Jurisdictional Delineation Report (LSA 2008) for a full description
of the delineation results.
The impact area has a direct connection to a designated navigable water of the United States.
Therefore, the Corps likely will verify that a "significant nexus determination" is not required. Under
Corps guidance, agencies will assert jurisdiction over navigable waters and their adjacent wetlands,
where "adjacent" is defined as "bordering, contiguous, or neighboring." Therefore, finding a surface
connection is not required to determine adjacency under this definition.
There is a total of0.098-7 acre of waters potentially subject to Corps jurisdiction, of which 0.0083
acre is nonwetland waters of the United States and 0.0904 acre is wetland waters (Figure 4).
CDFG. The drainage channel within the project study area and associated riparian vegetation meet
the CDFG definition of a streambed. LSA biologists assumed the limits of the disturbed tamarisk
scrub associated with the drainage channel to map the extent of potential CDFGjurisdiction in the
project study area.
The area delineated as potential CDFG jurisdiction was greater than, but entirely inclusive of, all
areas mapped as potentially subject to Corps jurisdiction and totaled 0.1504 acre (Figure 5).
A summary of potential jurisdictional areas is provided in Table C.

Habitat Fragmentation and Wildlife Movement
BIOLOGICAL RESOURCES REPORT
ROMERIA STREET DRAINAGE IMPROVEMENTS
CITY OF CARLSBAD, CALIFORNIA
Wildlife movement and habitat fragmentation are important issues in assessing impacts to wildlife.
Habitat fragmentation occurs when a proposed action results in a single, unified habitat area being
divided into two or more areas, such that the division isolates the two new areas from each other.
Habitat' isolation occurs when wildlife cannot move freely from one portion of the habitat to another,
or from one habitat type to another (e.g., the fragmentation of habitats within and around clustered
residential development). Habitat fragmentation also can occur when a portion of one or more
habitats is converted into another habitat, as when scrub habitats are converted into annual grassland
habitat by frequent burning. Fragmentation reduces the amount of habitat available to local wildlife
populations. In general, a reduction in available habitat is followed by a reduction in wildlife
populations because the remaining areas are too small to support prefragmentation population levels.
If the fragmentation is too great, wildlife populations will not be able to subsist, and some or all of the
species in a fragmented habitat area will disappear. This can occur on a local or regional scale,
depending upon the degree and type of fragmentation occurring. Fragmentation is particularly critical
for species that occupy already limited habitats, such as coastal sage scrub. If various stands of
coastal sage scrub are too fragmented to provide sufficient continuous cover, or are too isolated from
each other for an animal to move freely among various stands, that particular portion of the overall
habitat may be lost to use by certain species.
Based on the fragmented nature of the habitat within the project study area, the minimal nature of the
proposed impacts, and the location of the impacts within the project study area (i.e., the adjacency of
La Costa Avenue and residential development), LSA contends that the proposed project will neither
limit wildlife movement substantially nor contribute substantially to fragmentation of habitat.
IMPACTS
Temporary Impacts
Temporary impacts that may result from implementation of the proposed project include noise and
dust disturbance to birds and other wildlife utilizing habitat in and adjacent to the project impact area.
These disturbances will occur during construction activities for a limited duration. Existing conditions
include close proximity to a heavily traveled street (La Costa A venue) and associated vehicle noise.
Fugitive dust generated during construction will be reduced to appropriate levels according to
applicable ordinances and implementation of Best Management Practices (BMPs). Therefore, no
adverse effects on biological resources due to fugitive dust are anticipated. hnpacts associated with
noise generation are minimal and temporary in nature and do not constitute a significant change from
existing conditions.
Permanent Impacts
Permanent impacts include construction of an all-weather access road and turnaround pad to replace
the current access area from Levante Street. The impacts associated with installation of the access
road and pad are discussed in the following sections. Removal and replacement of the existing
concrete drainage, headwall, splash wall, and two brow ditches will not result in new additional
permanent impacts to the project area because they will retain the existing footprint.

Indirect Impacts
BIOLOGICAL RESOURCES REPORT
ROMERIA STREET DRAINAGE IMPROVEMENTS
CITY OF CARLSBAD, CALIFORNIA
Indirect impacts include disturbance to nesting birds or wildlife occupying habitat within or adjacent
to the project site due to construction noise and dust generation as discussed above. There is potential
for construction-related sediment to enter the water course and indirectly impact downstream habitat.
However, the project will be compliant with all applicable ordinances pertaining to stormwater
runoff, and the project design will implement BMPs during construction to minimize potential
impacts, which are discussed in more detail below.
Direct Impacts
Direct impacts to habitat are expected from construction of a maintenance road and pad off of La
Costa A venue to replace the current access from Levante Street. Vegetation in and around the
concrete-lined channel will be directly impacted during project construction. These direct impacts are
analyzed in more detail below.
Direct and permanent impacts to biological resources will occur as the result of the demolition of the
existing channel, brow ditches, and headwall, and construction of a new channel, brow ditches, a
debris barrier, a splash wall, riprap slope protection, a maintenance access road, and a turn-around
pad. These impacts are discussed in further detail below.
Vegetation Communities
The vast majority of direct project impacts will occur to areas classified as disturbed habitat;
however, impacts to coastal sage scrub, disturbed wetlands, and native and nonnative grasslands may
require mitigation according to the HMP. Table D lists the impacts of each project component to
vegetation communities on site and HMP-required mitigation ratios. Figure 3 shows the impacts to
vegetation communities.

CITY OF CARLSBAD, CALIFORNIA
Wildlife
Appendix C addresses the potential for special-status species to occur within the project study area.
Nesting Birds. Nesting birds may be affected if construction activities occur during the breeding
season (February 1 through August 31), either due to direct removal of the nest or disruption of
breeding activities by human-induced disturbance. Most species that nest in vegetation and structures
on the site tolerate the high levels of human activity occurring in the surrounding areas. However, to
ensure that project implementation will not impact nesting birds, recommended mitigation measures
to protect these creatures are detailed below.
Listed Species. The project will impact California adolphia, a CNPS List 2 plant species, which was
observed on site as a component of the coastal sage scrub vegetation community. No protections are
afforded to CNPS List 2 species or species with a CDFG SP designation under the HMP.
No special-status wildlife species were identified on site. Potentially suitable habitat for coastal
California gnatcatcher was identified on-site. Indirect impacts to coastal California gnatcatcher could
occur due to construction disturbance and loss of CSS habitat. The project area is not located in a
Core or linkage area and no observations of coastal California gnatcatchers have been recorded in the
project study area. However, to be consistent with the goals of the HMP, impacts to habitat within a
hardline preserve area that potentially could support the coastal California gnatcatcher will be subject
to HMP mitigation requirements described in Table D above.
Local and Regional Significance
The habitat within the project site is within a hardline preserve area, but is not part of a core or
linkage within the HMP. It is isolated from contiguous habitat and disturbed due to the proximity of
development. Because it is part of a hardline preserve area, the City of Carlsbad will consult with the
applicable resource agencies and obtain approval for the HMP compliance (i.e., Consistency
Findings) prior to the HMP compliance determination (i.e., Equivalency Findings).
Wildlife Movement Corridors
The project study area is highly fragmented and surrounded by roads and residential housing. The
project study area is not within a core area or linkage area as defined by the HMP. Currently, the
drainage is conveyed under La Costa A venue through a 48-inch diameter pipe that extends for
850 feet to an outfall structure. Wildlife species are not likely to use the culvert as a movement
corridor. There is potential for temporary impacts to wildlife movement during construction;
however, the short duration of construction is not expected to result in substantial impedances to
wildlife movement. Upon completion of construction, the site will provide the same wildlife
movement function as the existing situation. The project will not result in impacts to wildlife
movement beyond the existing conditions on site.

MITIGATION
BIOLOGICAL RESOURCES REPORT
ROMERIA STREET DRAINAGE IMPROVEMENTS
CITY OF CARLSBAD, CALIFORNIA
To avoid, minimize, and mitigate potential impacts to biological resources, the following mitigation
measures are recommended:
• Habitat restoration or enhancement will be performed to meet the HMP requirements for impacts
to coastal sage scrub, native grasslands, and nonnative grasslands. Mitigation will be required on
site or off site through preservation, creation, or restoration of habitat in accordance with the
mitigation ratios in Table D, above. Mitigation for impacts to unoccupied coastal sage scrub,
nonnative grassland, and disturbed lands may be fulfilled with out-of-kind mitigation if they are
contributing to assembly of a large contiguous habitat parcel, as discussed in Table 11 of the
HMP.
o The City will be responsible for providing mitigation for impacts to 0.099 acre of coastal sage
scrub habitat at a 1: 1 ratio (0.099 acre, or approximately 4,312 square feet) for scrub
unoccupied by coastal California gnatcatcher, or a 2: 1 ratio (0.198 acre, or approximately
8,625 square feet) for occupied coastal sage scrub pursuant to requirements of the HMP.
o For 0.003 acre of impacts to native grassland, the City will provide mitigation at a 3: 1 ratio
(0.009 acre, or approximately 392 square feet) of mitigation pursuant to the requirements of
theHMP.
o 0 .14 3 acre of impacts to nonnative grasslands will be offset by mitigation at a 0 .5: 1 ratio
(0.072 acre, or approximately 3,136 square feet) of mitigation pursuant to the requirements of
theHMP.
o 0.098 acre of impacts to disturbed habitat will be offset by mitigation at a 0.1: 1 ratio
(0.0098 acre, or approximately 427 square feet) at the Lake Calavera Mitigation Parcel
(personal communication with City Engineering Department, July 2008), which may involve
creation, preservation, or restoration of habitat.
• Implementation of construction or clearing of vegetation within the project impact footprint shall
occur outside of breeding season (February 15 through September 15). The USFWS will be
notified at least seven days before clearing and grubbing begins. During construction conducted
outside of the breeding season, a qualified biologist shall walk the area directly ahead of
construction equipment to flush birds from the area. The biologist will immediately report to the
USFWS the number and location of any federally listed birds disturbed by clearing and grubbing.
No gnatcatchers will be injured or killed. If construction must commence during breeding season,
then the City shall have a qualified biologist conduct a preconstruction survey for nesting birds,
including raptors, within three days of construction. Should nesting birds be detected within
100 feet of the project impact footprint, the USFWS will be notified immediately of any federally
listed species that are located during the preconstruction survey. A qualified biologist shall then
establish suitable buffer area (at least 300 feet) within which no construction activity may take
place until the nest is no longer active. Alternatively, the City can conduct surveys for coastal
California gnatcatcher to determine presence during the breeding season as described below.
Work may be allowed if no gnatcatchers are present.

o If construction activities are necessary during the breeding season, a qualified biologist will
conduct a focused species coastal California gnatcatcher survey in appropriate habitat within
and surrounding the project area. The surveys will consist of three visits, one week apart; the
last of these will be conducted no more than three days prior to construction, as required by
the draft Guidelines for Biological Studies (City of Carlsbad 2008).
• During the breeding season, construction noise shall be monitored regularly to maintain a
threshold at or below 60 dBA hourly Leq within 300 feet of breeding habitat occupied by listed
species. If noise levels supersede the threshold, the construction array will be changed or noise
attenuation measures will be implemented, as recommended in the draft Guidelines for Biological
Studies (City of Carlsbad 2008).
• Wetlands and jurisdictional habitat impacted by project construction will be replaced to ensure no
net loss of wetland resources. The City will comply with requirements of the HMP to mitigate
impacts to disturbed wetlands. An in-lieu mitigation fee or a commitment to wetland creation,
preservation, or restoration either on site or off site will be required per the HMP prior to project
approval. Wetland creation on site is not considered to be feasible due to the location of the
proposed project footprint. The City will be responsible for mitigating 0.077 acre of impacts to
ensure no net loss of disturbed wetlands. This measure will be required by the resource agencies
as a condition of the environmental permits.
• An MMRP will be prepared by the City prior to approval of the project and will be included with
resource agency permit application packages.
CONCLUSION
With incorporation of mitigation measures listed above, the project will be consistent with the HMP,
and federal and State requirements, and will have a minimal impact on biological resources within the
project study area.
