Dear Mr. Plummer:•p*
I* Dudek & Associates, Inc. (Dudek) conducted vegetation mapping, a wetlands delineation,
and a protocol-level, focused California gnatcatcher (Polioptila californica) survey for the
Highland Drive Storm Drain project alignment, City of Carlsbad (City), California. This
** study was completed according to your direction. The Highland Drive Storm Drain
P, replacement project includes an approximate 0.8-acre area (for purposes of this study, a 15-
foot buffer on either side of the project alignment was included for analysis). This letter
describes the methods used to obtain biological information, results, and provides a
•» discussion of the projects impacts and suggested mitigation measures along with required
"m permitting.
SITE DESCRIPTION
IM
The project area is an approximate 0.8-acre area situated between Highland Drive and
Hospital Park in the City of Carlsbad, San Diego County, California (Figure 1). Specifically,
the project area is located on the U.S. Geological Survey 7.5 minute San Luis Rey quadrangle;
m on Section 31; T11S, R4W (Figure 2). Elevations range from approximately 40 feet above
y mean sea level (AMSL) at the northern end to 120 feet AMSL at the southern end. The
proj ect area is dominated by disturbed coastal sage scrub/southern mixed chaparral and urban
m development/ornamental plantings but also contains other vegetation communities as
ll described below. A Community Park lies at the western end and the entire proj ect alignment
is within a single residential lot.m
fi :<* The project is situated within the City's Habitat Management Plan (HMP) Local Facilities
Management Zone 1 within a Development Area outside of any HMP Core, Linkages, Special
£, Resource, Existing Hardline Conservation, Proposed Hardline Conservation, or Proposed

METHODOLOGY
Data regarding biological resources present on the project site were obtained through a review
of pertinent literature and through field reconnaissance.
Sensitive biological resources present or potentially present onsite were identified through
a literature search using the following sources: U.S. Fish and Wildlife Service (2000),
California Department of Fish and Game (2004 a-e), California Native Plant Society's
Inventory of Rare and Endangered Vascular Plants (CNPS 2001), Murphy (1990), scientific
literature, and reports. General information regarding wildlife species present in the region
was obtained from Unitt (1984) for birds, Bond (1977) for mammals, Stebbins (2003) for
reptiles and amphibians, and Emmel and Emmel (1973) for butterflies. In addition, soils maps
of San Diego County (Bowman 1973) were examined. The project area is located within the
North County Wildlife Forum's study area; hence, vegetation and sensitive species maps
generated for the Multiple Habitat Conservation Plan (MHCP) (2000) and HMP (1999) also
were reviewed.
Biological surveys of the project area were conducted by Dudek biologists Brock A. Ortega
(BAO), Cathleen M. Weigand (CMW), and Megan S. Enright (MSE), according to the
schedule illustrated in Table. 1. Plant communities were mapped in the field directly onto a
20-scale (1" = 20') engineering plan (City of Carlsbad Engineering Department 2003), which
included a topographic base. Plant community boundaries were manually drawn onto the
engineering plans. The extent of wetlands features was determined in the field by collecting
data using a Global Position System (GPS) backpack unit; this shape was transferred to a
topographic base. The plant and wetland community boundaries were digitized using
Arc View. Plant and wetland community boundaries were digitized by Dudek GIS technician
Tim Walsh using ArcCAD to calculate acreages of the habitat types and impacts of the
proposed project.
The vegetation classifications used in this report for mapping purposes follows Holland
(1986).
Botanical surveys of the site were conducted September 18, October 7, and December 1,2003.
All plant species encountered during the field surveys were identified and recorded. Latin and
common names of plants follow Thejepson Manual (Hickman 1993). A cumulative list of
plant species observed on the property during the surveys is presented in Appendix A.
A jurisdictional delineation of "waters of the United States," including wetlands, under the
jurisdiction of the Army Corps of Engineers (ACOE), the California Department of Fish and
Game (CDFG), and the Regional Water Quality Control Board (RWQCB) was conducted on

December 1, 2003. This jurisdictional wetlands delineation was conducted in accordance
with the 1987 U.S. Army Corps of Engineers Wetlands Delineation Manual (TR Y-87-1);
hydrology, vegetation and soils were examined within the adjacent open channel.
Hydrophytic vegetation associated with a stream channel was used to determine the
wetlands regulated by CDFG. The limits of areas under the jurisdiction of the RWQCB
primarily match those areas delineated as ACOE-jurisdictional. As mentioned, jurisdictional
features were mapped using a GPS unit, transferred to a topographic base and digitized using
ArcView.

Wildlife species detected during field surveys by sight, vocalizations, burrows, tracks, scat,
or other sign were recorded. Binoculars (8 x 32 power) were used to aid in the identification
of observed wildlife. In addition to species actually observed, expected wildlife use of the site
was determined by known habitat preferences of local animal species and knowledge of their
relative distributions in the area. Latin and common names of animals referred to in this
report follow Stebbins (2003) for reptiles and amphibians, American Ornithologists' Union
(1983, 2003) for birds, Jones et al. (1992) for mammals, and Emmel and Emmel (1973) for
butterflies.
A focused survey for California gnatcatcher was completed in September 2003 following the
most recent U.S. Fish and Wildlife Service (USFWS) protocol (1997), under the authority of
USFWS permit #TE813545-4. The survey consisted of three visits, separated by seven to
10 days. Each visit consisted of walking all portions of the proposed project alignment within

suitable habitat while listening for California gnatcatcher "mewing" or "pish" calls. A tape
recording of a male California gnatcatcher was played approximately every 50 feet depending
on sound attenuation due to topography. The surveys were conducted under appropriate
field conditions (Table -/).
RESULTS
BOTANICAL RESOURCES
Based on species composition and general physiognomy, seven associations (sparse coastal
sage scrub and coastal sage scrub are considered one plant association) were identified within
the project study area (Table 2). Figure 3 depicts their spatial distribution and discussions
specific to each are provided in the following sections.

Coastal Sage Scrub & Variations
Coastal sage scrub is a native plant community composed of a variety of soft, low, aromatic
shrubs characteristically dominated by drought-deciduous species. Typical species include
black sage (Salvia mdlifera), California sagebrush (Artemisia californica), California bush
sunflower (Encelia californica), and flat-topped buckwheat (Eriogonum fasciculatum). Scattered
evergreen shrubs, including lemonadeberry (Rhus integrifolia), laurel sumac (Malosma laurina),
and toyon (Heteromeles arbutifolia), are present throughout the coastal sage scrub and tend to
dominate in the more mesic areas, such as north-facing slopes.
Onsite the sparse coastal sage scrub is similar in composition to coastal sage scrub but has
been invaded by ornamental and non-native species, and disturbed by erosion and human

activities within the canyon. Non-native and/or ornamental species include black mustard
(Brassica nigra), wild oat (Avena fatua), bromes (Bromus diandrus, B. madritensis, B. hordeaceus),
hottentot-fig (Carpobrotus edulis], and bougainvillea (Bougainvillea sp.). Approximately 0.07
acre of coastal sage scrub and 0.06 acre of sparse coastal sage scrub was identified and mapped
within the study area.
Disturbed Coastal Sage Scrub/Southern Mixed Chaparral
Disturbed coastal sage scrub/southern mixed chaparral is similar in composition to coastal
sage scrub mixed with typical southern mixed chaparral habitat species. Southern mixed
chaparral species onsite include chamise (Adenostoma fasciculatum), mission manzanita
(Xylococcus bicolor), lemonadeberry and toyon. This area was mapped as "disturbed coastal
sage scrub/southern mixed chaparral" because it represents a transitional area or ecotone
between these two vegetation communities. Approximately 0.4 acre of disturbed coastal sage
scrub/southern mixed chaparral was identified and mapped within the study area
Eucalyptus Woodland
Eucalyptus woodland is not recognized as a native plant community by Holland (1986).
Nonetheless, it is a distinct vegetational association within the study area dominated by
eucalyptus trees (Eucalyptus sp.). This association is characterized onsite by a canopy of
eucalyptus with an understory of sparse non-native shrubs, herbs and grasses such as western
ragweed (Ambrosia, psihstachya var. californica), jade plant (Crassula argentea), wild oat, foxtail
barley (Hordeumjubatuni), and purple needlegrass (Naselta pulchra). Approximately 0.02 acre
of eucalyptus woodland was identified and mapped within the study area.
Open Channel
Open channel refers to jurisdictional waters characterized as an intermittent stream channel
that is barren or sparsely vegetated; it is not a jurisdictional wetlands because of the lack of
hydrophytic vegetation. Within the project site, the area identified as open channel is highly
disturbed due to human activities, erosion and scouring during infrequent flood and rain
events. This unvegetated stream channel is regulated by the CDFG, pursuant to Section
1601-1603 of the California Fish and Game Code; the ACOE, pursuant to Section 404 of the
Clean Water Act; and the RWQCB pursuant to Section 401 of the federal Clean Water Act.
Approximately 0.06 acre (approximately 225 linear feet) of open channel was identified and
mapped within the study area.

Giant reed (Arundo donax] dominates a small area on the northwestern slope of the canyon.
This area is completely dominated by giant reed with no other canopy or understory species
present. Giant reed is a highly invasive non-native species that often displaces native wetland
vegetation, especially in areas of frequent scouring. This unvegetated stream channel is
regulated by the CDFG only, pursuant to Section 1601-1603 of the California Fish and Game
Code. This patch of giant reed is above the ordinary high mark and not under the j urisdiction
of the ACOE or RWQCB. Less than 0.01 acre (147 square feet) of giant reed was identified
and mapped within the study area.
Developed/Ornamental
Developed/Ornamental describes areas occupied by structures, paving and other impermeable
surfaces, and areas where ornamental plant species and landscaping have been installed
and/or are maintained. Within the study area, developed/ornamental occurs on the southern
portion of the project area. Ornamental plantings onsite consist of ornamental shrubs, herbs
and grasses such as hottentot-fig, bougainvillea, and jumper (Junipems sp.). Approximately
0.2 acre of developed/ornamental planting was identified and mapped within the study area.
Disturbed Habitat
Disturbed habitat is not recognized as a vegetation community by Holland (1986). Disturbed
habitat areas generally are the result of frequent, often mechanical disturbance, allowing the
invasion of non-native species. The disturbed habitat onsite is sparsely vegetated and is
characterized by non-native plants species such as black mustard, wild oat, bromes,
hottentot-fig, bougainvillea, Australian saltbush (Atriplex semibaccata), Russian-thistle, and
tocalote (Centaurea melitensis).
Floral Diversity
A total of 52 vascular plant species were recorded in the project area. Of the 52 species
identified, 29 species (58%) are native. The full list of plant species identified onsite is
provided as Appendix A.

WILDLIFE RESOURCES
A list of wildlife species detected by Dudek is included in Appendix B. A total of 20 species
of birds was observed onsite. The most commonly encountered species include mourning
dove (Zenaida. macroura) and California towhee (Pipilo crissilis). Based on the habitats present
onsite, a number of migratory birds, raptors, and disturbance tolerant songbirds probably use
the area. Additionally, night birds such as owls and nighthawks probably use the project
area.
No amphibian species and two reptile species were detected including side-blotched lizard
(Uta stansburiand) and western fence lizard (Scelopoms occidentalis). Other reptile and
amphibian species which may be present include southern alligator lizard (Gerrhonotus
multicarinatus webbit), orange-throated whiptail (Cnemidophoms hyperythrus), western skink
(Eutneces skiltonianus), ringneck snake (Diadolphis punctatus), gopher snake (Pituophis
melanoleucus), northern red-diamond rattlesnake (Crotalus ruber ruber], Pacific slender
salamander (Batrachosepspacificus], and western toad (Bufo boreas). None of these species are
federally- or state-listed and none are expected to occur.
Three mammal species were detected onsite including, brush rabbit (Sylvilagus bachmannii),
California ground squirrel (Spermophilus beecheyf), and Botta's pocket gopher (Thomomys
hottae). Other mammals which may use the site include, Virginia opossum (Didelphis
virginiana), striped skunk (Mephitis mephitis), bats, and rodents. None of these species are
state- or federally-listed and none are expected to occur.
SENSITIVE BIOLOGICAL RESOURCES
Sensitive biological resources are those defined as follows: (1) species that have been given
special recognition by federal, state, or local conservation agencies and organizations due to
limited, declining, or threatened population sizes; and (2) habitat areas or plant communities
that are unique, are of relatively limited distribution, or are of particular value to wildlife.
During the field surveys a special effort was made to identify and survey those areas
suspected to support sensitive resources.
This section includes discussions of plant and animal species present in the project vicinity
that are given special recognition by federal, state, or local conservation agencies and
organizations owing to declining, limited, or threatened populations. Sources used for
determination of sensitive biological resources are as follows: wildlife - USFWS (2000),
CDFG (2000 a and e), Remsen (1978), McGurty (1980), and Murphy (1990); plants - USFWS
(2000), CDFG (2000 b and d), and CNPS (2001); habitats - Holland (1986).

Sensitive Habitats
Sensitive habitats are those that are considered rare or declining in the region or support
sensitive plant and/or wildlife species. The following habitat types are considered sensitive
and require mitigation: coastal sage scrub (disturbed, sparse, and areas with southern mixed
chaparral), open channel, and giant reed.
Coastal sage scrub habitat has been the focus of numerous conservation planning efforts in
southern California. This plant community, along with its associated plant and animal
constituents, has been seriously affected by development and other human-related activities.
In the late 1980s, it was estimated that upwards of 85 percent of coastal sage scrub had been
lost. As a result, in 1991 the state of California initiated its first habitat-based conservation
planning effort, the NCCP program, selecting coastal sage scrub as its pilot community type.
Approximately 75 sensitive plant and animal species are associated with coastal sage scrub,
the most notable of which is the federally-listed threatened California gnatcatcher. As such,
this plant community is considered to be sensitive by state and federal resource agencies,
most southern California jurisdictions, and local conservation organizations. Coastal sage
scrub variations, including sparse coastal sage scrub and the ecotone with southern mixed
chaparral, is included as a sage scrub habitat because it functions in much the same way as
coastal sage scrub, especially when it is intermixed with coastal sage scrub. It provides
habitat for a number of sensitive plant and animal species, including the California
gnatcatcher the NCCP "target species".
As mentioned, the open channel is habitat are under the jurisdiction of the CDFG, pursuant
to Section 1601-1603 of the California Fish and Game Code, the ACOE, pursuant to
Section 404 of the Clean Water Act, and the RWQCB pursuant to Section 401 of the federal
Clean Water Act. The giant reed is under the jurisdiction of CDFG only pursuant to Section
1601-1603 of the California Fish and Game Code.
PROJECT IMPACTS
This section addresses impacts to biological resources that would result from the project and
provides analysis of significance for each potential impact. Impacts to biological resources
can be direct - resulting from the permanent removal of habitat, or indirect - resulting from
changes in land use adjacent to natural habitat (e.g., increased light, noise, and urban runoff,
interruption of wildlife movement, etc.). Both of these types of impacts and their levels of
significance are discussed in this section.
The following criteria are used to determine the significance of an impact:

Substantial effect on a rare or endangered plant or animal or habitat of that species
is considered a significant impact.
Substantial interference with the movement of any resident or migratory fish or
wildlife species is considered a significant impact.
Substantial reduction of habitat for fish, wildlife, or plants is considered a
significant impact.
Impacts require the issuance of specific resource agency permits, waivers, or
coordination.

Indirect impacts to adjacent vegetation communities, such as coastal sage scrub, primarily
would result from adverse "edge effects" as cited above. For the proposed project, the
potential indirect impacts resulting from construction activities include dust, noise, and
general human presence that may temporarily disrupt species and habitat vitality and lead
to construction-related soil erosion and runoff. However, all project grading will be subject
to the typical restrictions (e.g., Best Management Practices (BMPs)) and requirements that
address erosion and runoff, including the federal Clean Water Act, NPDES, and preparation
of a SWPPP. BMPs would include, but are not limited to, placement of silt fencing, haybales,
and/or sandbags in potential drainage areas, periodic watering of the grading area, and snow

Due to the nature of the project, there would not be long-term, indirect impacts to
vegetation communities onsite including impacts associated with increased human presence,
lighting, etc.
The proposed alignment project would not impact the adjacent open channel. However, due
to the proposed project's proximity to the open channel, rip-rap shall be installed by hand
(outside of the channel only), silt fencing will be installed, and a biological monitor is
recommended to be present during construction in this area to ensure no impacts occur to
downstream waters.
Impacts to Sensitive Plants
No sensitive plant species were identified during the field survey. Although surveys were
conducted late in the season, the nature of the habitats onsite are disturbed, which appears
to be the result of erosion, human disturbance, and the invasion of non-native and
ornamental species. Due to the existing conditions of the project area and continued
activities that have occurred within the majority of the surrounding area, it is highly unlikely
that any sensitive plant species would occur on the property; therefore, implementation of
the proposed project would not directly impact any sensitive plant species. Likewise, no
indirect impacts to sensitive plant species are expected.
Impacts to Sensitive Wildlife
The only potential listed species which might occur on site is the California gnatcatcher;
however focused surveys were negative. Therefore, the proposed project will not have a
direct impact on federally- or state-listed wildlife. There is some potential for other sensitive
species to occur on site; however, these species are likely to temporarily vacate the area once
work begins and no direct impacts would occur.
Indirect impacts to breeding birds may occur if activities occur during the breeding season.
These impacts would be associated with grading activities and temporary. These indirect
impacts can be avoided by constructing outside the breeding season (February 15th - August
31st) or assuring that construction activity will not result in noise levels above 60 dBA leq at
the nest site.

If construction activity is to take place during the breeding season (i.e., January through
September), a one-time biological survey for nesting bird species must be conducted within
the proposed impact area at least 72 hours prior to construction. This survey is necessary to
assure avoidance of impacts to nesting native birds (per the federal Migratory Bird Treaty
Act). If nesting birds are detected within vegetation which is to be impacted, the nest
location(s) shall be protected until fledging of young is complete.
SUMMARY OF SIGNIFICANCE AND SUGGESTED MITIGATION & PERMITTING
As mentioned, coastal sage scrub is considered a sensitive habitat by local, state and federal
agencies and is covered by the City of Carlsbad's HMP. Loss of 0.2 acre of coastal sage scrub,
sparse coastal sage scrub, and coastal sage scrub/southern mixed chaparral is considered
significant and would require mitigation.
Impacts to 0.01 acre of eucalyptus woodland is not considered significant because this
vegetation community is a non-native, invasive vegetation community that provides little
biological resource value.
Non-developed lands, including eucalyptus woodland, are covered under the HMP. In
accordance with the HMP, proposed impacts to this habitat type require an in-lieu fee as
determined by the City Council.
Coastal Sage Scrub & Upland Habitats Mitigation Strategy
The HMP was approved by City Council on 17 June 2003, and has also been approved by the
Coastal Commission. However, the USFWS has not processed a Biological Opinion on it yet,
so in effect it has not been implemented. Under the HMP, as approved by the City and
Coastal Commission, the City would require that project pay a fee to the City on a per acre
basis for impacts to non-developed lands (i.e., eucalyptus woodland). Impacts to unoccupied
coastal sage scrub would be either mitigated off site at a 1:1 ratio or through paying an in-liew
fee determined by the City Council. Assuming that the City would like to follow the HMP
standards, mitigation for coastal sage scrub habitats will occur by preserving comparable
acreage at the City-owned Calaveras Lake Mitigation Bank.
If the City does not wish to wait for the USFWS Biological Opinion, then it may pursue a
Section 4(d) Deminimus Exepmtion under the federal Endangered Species Act. This allows the
City to exceed its 5% coastal sage scrub take allowance. In order to utilize the exemption,
the City must prove 1) that the project will impact less than an acre of coastal sage scrub; 2)
coastal sage scrub habitat is not occupied by California gnatcatcher, and; 3) that impacts to
habitat will not affect California gnatcatcher recovery. All of these conclusions can be made
for this project.

Assuming that the City will utilize the strategy outlined for the HMP, mitigation for impacts
to disturbed coastal sage scrub/southern mixed chaparral and sparse coastal sage
include setting aside 0.2 acre of coastal sage scrub specific habitat at the Lake
scrub will
Calaveras
Mitigation Bank. Impacts to other non-developed lands (i.e., eucalyptus woodland) shall be
mitigated through the payment of a fee to the City on a per acre basis.

Species Sensitivity Categories
APPENDIX C
SPECIES SENSITIVITY CATEGORIES
Federal (1996)
Endangered. Taxa threatened throughout all or a significant portion of their
range.
Threatened. Taxa likely to become endangered in the foreseeable future.
Category 1. Taxa for which the USFWS has enough information on
biological vulnerability and threat(s) to support listing them as
endangered or threatened species.
Category 2. A category formerly used for taxa for which information in
possession of the USFWS indicated that listing as endangered or
threatened may be appropriate but for which sufficient data to
support the preparation of rules were unavailable. This category
has been eliminated owing to its frequent misinterpretation.
Category 3. Taxa that were once considered for listing as endangered or
threatened, but are currently not receiving such consideration.
These taxa are included in one of the following three
subcategories.
Subcategory 3A: Taxa presumed to be extinct.
Subcategory 3B: Taxa whose names do not meet the Endangered Species Act's
legal definition of species.
Subcategory 3C: Taxa now considered to be more widespread that originally
thought.
Note: The taxa in Categories 1 and 2 are candidates for possible addition to the list of
endangered and threatened species. The USFWS encourages their consideration in
environmental planning.

Endangered. Taxa which are in serious danger of becoming extinct throughout all, or
a significant portion, of their range due to one or more causes including
loss of habitat, change in habitat, over exploitation, predation,
competition, or disease (Section 2062 of the Fish and Game Code).
Threatened. Taxa which, although not presently threatened with extinction, are likely
to become endangered species in the foreseeable future (Section 2067 of
the Fish and Game Code).
Rare. Taxa which, although not presently threatened with extinction, are
present in such small numbers throughout their range that they may
become endangered if the present environment worsens (Section 1901 of
the Fish and Game Code).
Candidate. Taxa which the Fish and Game Commission has formally noticed as being
under review by the Department in addition to the list of threatened and
endangered species.
