The Crossings at Carlsbad Holes No. 2 and 3
Emergency Golf Access Path
1.0 BACKGROUND
This biological equivalency analysis report examines the removal of land from Carlsbad Habitat
Management Plan (HMP) lands to provide for emergency vehicle access to Hole No. 3 at The
Crossings at Carlsbad. In accordance with the Carlsbad HMP, lands removed from the preserved
lands must be replaced with land of equivalent acreage and biological resources to maintain
HMP lands at a constant size and habitat quality. This report demonstrates equivalency for minor
adjustments to City of Carlsbad (City) HMP lands at The Crossings at Carlsbad to establish
emergency access to the golf course under the flight path ofthe McClellan Palomar Airport.
Prior to constmction of The Crossings at Carlsbad, the project site contained a network of dirt
roads used by the property owner for agricultural operations and by San Diego Gas and Electric
Company to monitor and maintain the high-tension power lines and high-pressure gas lines
crossing the property. The approved plans for the golf course called for the access road between
Golf Holes No. 2 and 3 to be abandoned and revegetated with a seed mix called "enhanced
revegetation" containing several native annuals and the perennial exotic weed Australian
saltbush (Atriplex semibaccata).
On July 3, 2007, an airplane crashed on take-off from the adjacent McClellan Palomar Airport.
The plane and buming fuel crashed on and around the No. 3 green. This disasttous event
revealed the need for emergency access to a portion of the golf course that was accessible to
emergency vehicles. The City proposes to remove the area of an existing unpaved road from the
HMP lands to provide emergency access to Hole No. 3 that lies under the Carlsbad airport flight
path. In exchange, an equivalent area will be added to the HMP lands to compensate for the lost
acreage and biological values.
The proposed emergency access plan calls for the existing unpaved access road between Golf
Holes No. 2 and 3 to be paved with concrete to provide an all-weather access path. The distance
between the Hole No. 2 tees and the Hole No. 3 green is approximately 600 feet by way of the
old dirt access road. The area to be removed from the HMP will be 14 feet wide to provide for a
12-foot-wide paved access path and two 1-foot shoulders. Minimal grading may be required to
prepare the existing roadbed for paving. Any grading that does occur shall not extend beyond the
14-foot-wide area and will not impact any sensitive resources, such as the adjacent patch of
Diegan coastal sage scmb. There will be no significant topographical changes to the hillside, nor
are there any changes to the basic drainage pattems for the area. The path will be curbed on the
downhill edge to direct mnoff to the golf course area at Hole No. 2.
The Carlsbad HMP contains provisions that allow for minor changes such as the one proposed
by the City for the emergency access path between Golf Holes No. 2 and 3. The proposed golf
course change results in minor adjustments to HMP lands, project habitat impact acreages, and
4821-07
DUDEK 1 October 2008
The Crossings at Carlsbad Holes No. 2 and 3
Emergency Golf Access Path
will result in a minor increase in Diegan coastal sage scmb revegetation acreage in the HMP
(Figure 1). The changes do not result in a reduction of HMP lands within the golf course, nor is
there any net loss of habitat values, corridor linkages, or reduce long-term viability ofthe habitat.
As such, these modifications are consistent with the intent of the HMP and the policies and
agreements the City has made with the various wildlife agencies.
In November 2007, the Califomia Coastal Commission approved Coastal Development Permh
Amendment No. 1 for the project that made similar minor adjustments to the HMP lands. That
amendment removed 1.87 acres and added 1.902 acres of equivalent area to the HMP to increase
the distance of Hole No. 18 and to provide an emergency access and maintenance path between
Holes No. 13 and 16.
The Crossings at Carlsbad Golf Course is considered a "hardline" area. Minor changes are
approved through an Equivalency Finding, as outlined in Section 20.1 (4) of the Implementing
Agreement by and among The City of Carlsbad, The California Department of Fish and Game,
and the U.S. Fish and Wildlife Service to Establish the Habitat Management Plan for the
Conservation of Threatened, Endangered and Other Species in the City of Carlsbad, California
(City of Carisbad 2004).
Because the access path between Golf Holes No. 2 and 3 and the replacement HMP lands lie
within the Coastal Zone, the City is submitting an application for an amendment to Coastal
Development Permh No. 6-CII-00-087-A2 to modify HMP hardlines. The City Planning
Department, Califomia Department of Fish and Game, and the U.S. Fish and Wildlife Service
shall also be given the opportunity to review the findings, and comment if they choose to do so,
before the proposed changes are final.
This report has been prepared to demonstrate that policies to protect environmentally sensitive
species and habitat area are satisfied by the equivalency findings analysis and are in compliance
with the Califomia Coastal Act, the Carlsbad Local Coastal Program (LCP), and the Carlsbad
HMP.
2.0 BIOLOGICAL ANALYSIS OF THE AREA REMOVED FROM THE
HMP
The following analysis provides a comparison of biological resources present at the proposed
emergency access path and on the land proposed to be added to the HMP lands.

Emergency Golf Access Path
2.1 Vegetation
Vegetation mapping for the Crossings at Carlsbad Golf Course project was conducted according
to Holland, and the same vegetation community classifications are used in the HMP for Natural
Communities in the City. These vegetation community classifications are used in this report for
consistency.
Vegetation communities mapped in the vicinity of the golf course emergency access path
between Golf Holes No. 2 and 3 and the proposed replacement acreage include non-native
annual grassland and Diegan coastal sage scmb.
Non-native annual grassland. This plant community is disturbance-related, in this case, from
previous agricultural activities. The vegetation is usually dominated by annual grasses, such as
bromes (Bromus spp.) and wild oats (Avena spp.), and other dismrbance-tolerant broadleaved
species such as filarees (Erodium spp.), telegraph weed (Heterotheca grandiflora), and
doveweed (Eremocarpus setigerus), among others. Non-native grassland is not considered a
sensitive habitat type in the HMP.
Diegan coastal sage scrub. This is a native plant community characterized by a variety of soft,
low, aromatic, drought-deciduous shmbs, such as Califomia sagebmsh (Artemisia californica),
Califomia buckwheat (Eriogonum fasciculatum), Califomia bush sunflower (Encelia
califomica), and sages (Salvia spp.), with scattered evergreen shmbs, including lemonadeberry
(Rhus integrifolia), laurel sumac (Malosma laurina), and toyon (Heteromeles arbutifolia).
Diegan coastal sage scmb typically develops on south-facing slopes and other xeric situations.
Diegan coastal sage scmb is considered a sensitive habitat type because of its depleted nature
and the large number of sensitive plant and wildlife species that it supports, such as the federally
listed threatened coastal Califomia gnatcatcher (Polioptila californica californica).
2.2 Existing Vegetation Resources
The golf course emergency assess path between golf holes No. 2 and 3 to be removed from the
HMP consists of an existing, abandoned San Diego Gas and Electric Company unpaved dirt
road. Though the road was and remains non-vegetated, it was mapped as non-native grassland in
the vegetation mapping that was performed for the project (P&D Environmental 2005). A patch
of Diegan coastal sage scmb is adjacent to the access road on the east side, along with non-native
grassland. Dudek documented a pair of coastal Califomia gnatcatchers with three juveniles in
this area in July 2008 (Dudek 2008a). The observed gnatcatcher use area is shown on Figure I.
The area west of the access road has been planted with coastal sage scmb species as part of the
golf course constmction work. The golf course constmction plans originally called for the road
to be planted with a seed mix called "enhanced revegetation" that contained both annual native

species and Australian saltbush, a perennial exotic weed. The seed mix was modified to contain
only native coastal sage scmb species during golf course constmction. Figure 2 shows photo
views of the access road between Golf Holes No. 2 and 3 taken in August 2008.
While adjacent to Diegan coastal sage scmb habitat, the non-vegetated dirt road between Golf
Holes No. 2 and 3 is of little value for most of the typical Diegan coastal sage scmb wildlife
species and contains no sensitive plant species. The area lacks the constiment habitat components
to support the primary biological needs (such as communicating, roosting, foraging, nesting,
reproduction, rearing of young, dispersal, or sheltering) of the coastal Califomia gnatcatcher and
other wildlife species that utilize sage scmb. As such, the area is unlikely to be used by coastal
Califomia gnatcatchers and would not be considered an Environmentally Sensitive Habitat Area
(ESHA), as defined by Public Resources Code Section 30107.5. Because the golf course plans
identified the area for "enhanced revegetation" and did not call for this area to be used for
Diegan coastal sage scmb mitigation or revegetation, it would likely have remained in its non-
vegetated condition for the foreseeable future.
2.3 Existing Wildlife Resources
The golf course design avoided and minimized impacts to wildlife habitat and species of concem
to the maximum extent practicable. Prior to golf course constmction there were no sensitive
wildlife resources in the area around the proposed golf course emergency access path between
golf holes No. 2 and 3. Coastal Califomia gnatcatcher sightings were observed approximately
800 feet to the northwest across College Boulevard, approximately 1,400 feet to the northeast,
and 1,600 feet to the southwest (P&D Environmental 2003). The patch of Diegan coastal sage
scmb adjacent to the emergency access path between golf holes No. 2 and 3 was not occupied by
coastal Califomia gnatcatcher.
In 2008, a pair of Califomia gnatcatcher established a breeding territory in coastal sage scmb
habitat immediately adjacent to the proposed emergency access path. The road essentially forms
the westem boundary of the territory. However, the area to be removed from HMP land does not
support gnatcatcher habitat nor does it provide any biological functions and services for this
gnatcatcher pair.
2.4 Buffers
Only the riparian areas of the golf course were required to have a biological buffer zone between
the course play areas and native habitat, consistent with Section 7-13 of the second addendum of
the Carlsbad HMP. Buffers for upland habitat are not required. No buildings, parking lots, or
other hard development features typically requiring biological buffers are planned for the access

path between Golf Holes No. 2 and 3. Because the closest wetiand is approximately 1,500 feet
from the proposed access path between Golf Holes No. 2 and 3, a biological buffer would not be
required to protect wetland resources at this location.
The Diegan coastal sage scmb and non-native annual grassland adjacent to the access path
between Golf Holes No. 2 and 3 could be considered ESHA, as defined by Public Resources
Code Section 30107.5, but this low-intensity emergency access path through open space would
not significantly dismpt habitat functions and values. The access path will not be used by golf
patrons. The access path between Golf Holes No. 2 and 3 without any biological buffers is in
conformance with Public Resources Code Sections 30240 (a) and (b). The absence of a buffer
would also be consistent with other golf course turf and dirt or paved path areas that abut
sensitive upland habitat throughout the project.
3.0 BIOLOGICAL ANALYSIS OF THE AREA TO BE ADDED TO THE
HMP
This section presents the biological resources that are present within the area proposed to be
added to the HMP lands in compensation for the removal of the emergency access path. The
inclusion area of 0.23 acre will be added to the HMP to compensate for the 0.15 acre removed
for the emergency access path between Golf Holes No. 2 and 3 (Figure 1). Figure 3 shows photo
views of the areas that are being added to the HMP in place of the acreage lost due to the golf
maintenance and emergency access path between Golf Holes No. 2 and 3.
3.1 Existing Vegetation Resources
The new HMP area was originally mapped as non-native annual grassland, but has been planted
with coastal sage scmb species and is being actively maintained and monitored as part of the
project's habitat mitigation. The area currently is in an early stage of conversion to coastal sage
scmb and consists of a mixmre of non-native annual grasses, annual weeds, and young coastal
sage scmb plants. Over the next few years the area will become Diegan coastal sage scmb as the
plants grow and mature, crowding out most of the annual grasses and other annual weed species.
The replacement acreage planted with coastal sage scmb species provides higher habitat
functions and values than non-native annual grassland, especially for sage scmb dependent
species as the coastal Califomia gnatcatcher.

3.2 Existing Wildlife Resources
Dudek has been monitoring coastal Califomia gnatcatchers at the Crossings Golf Course since
the completion of golf course constmction in 2007. In 2007, Dudek documented 8 pairs of
coastal Califomia gnatcatchers, which produced 3 fledglings (Dudek 2007). In 2008, Dudek
documented 10 pairs of coastal Califomia gnatcatchers, which produced 16 fledglings. One of
the pairs is located within the canyon that is immediately west of the proposed HMP land
addition (Dudek 2008a). Based on Dudek's experience at the Tmmp National Golf Club in Los
Angeles (Dudek 2008b and 2008c), the number of coastal Califomia gnatcatchers will continue
to increase at the Crossings at Carlsbad Golf Course as the 40 plus acres of coastal sage scmb
vegetation planted as mitigation and revegetation continues to mature and provide suitable
habitat.
4.0 EQUIVALENCY ANALYSIS
The comparison of biological resources to be added and removed from HMP lands is
summarized in Table I. The lands being added to the HMP will provide additional Diegan
coastal sage scmb habitat to the HMP, consistent with HMP goals for the coastal Califomia
gnatcatcher. The new HMP lands will solidify and improve wildlife corridor connectivity, and
are consistent with Mello II LUP and the Carlsbad HMP Section 7-13. No adverse impact to
coastal resources will result from this action and it is consistent with the resource protection
policies of Chapter 3 of the Coastal Act and the certified Mello II LUP Land Use Plan.

4.1 Vegetation Resources
The replacement acreage will be suitable for coastal Califomia gnatcatcher use as it matures and
attains the necessary stmcmre and biomass. There is a high probability the replacement area will
successfully provide biological functions and services that are beneficial to Califomia
gnatcatcher because the area is mitigation land that will be actively maintained and monitored for
a five year period. Performance criteria established for mitigation areas of the golf course require
minimum standards of habitat maturity before maintenance and monitoring is allowed to end. In
contrast, the emergency access road will likely remain unvegetated due to soil compaction and
4821-07

the loss of topsoil from historic road uses. Therefore, the land being added to the HMP will be of
equal or greater habitat value suitable for sensitive species, such as coastal Califomia
gnatcatcher, than the land removed for the emergency access path between Golf Holes No. 2 and
3.
4.2 Wildlife Resources
Although a Califomia gnatcatcher breeding territory is located adjacent to the area to be
removed, no habitat will be removed because there is presently an unpaved road where the new
emergency access will be built. The road creates an edge to the existing habitat, but is not
expected to create any barrier to gnatcatcher movement, especially after enhanced revegetation
areas mamre with coastal sage scmb vegetation.
The mitigation area to be added to the HMP will develop into mature coastal sage scmb habitat
under the guidance of the five-year monitoring and maintenance program. Therefore, this area
will provide new biological resources for dispersing gnatcatcher fledglings for forage and nesting
activities.
4.3 Buffer
Biological buffers were not required for upland habitats in the HMP and other environmental
permits, only wetland habitats were required to have buffers. Because the lands being removed
and added are uplands, there are no buffer zones required with the area being added to HMP.
This is consistent with Section 7-13 of the second addendum of the Carlsbad HMP. In addition,
experience at Tmmp National Golf Club demonstrates that gnatcatchers are capable to over fly
golf cart paths that experience greater frequency of use than the proposed emergency access road
and similar to the cart path adjacent to the area being added.
4.4 Critical Habitat Corridor Size and Value
There are no changes in any critical habitat corridor size or value that would negatively impact
the coastal California gnatcatcher or any other sensitive species in the area. Coastal Califomia
gnatcatcher has been documented to successfully occupy suitable habitat located within and
around golf courses. At the Tmmp National Golf Club in Rancho Palos Verdes, coastal
Califomia gnatcatchers have been documented to utilize restored interior golf course habitats
from 2005-2008 (Dudek 2006, 2008b, 2008c). In 2005, utilization of interior habitat slopes and
pockets primarily consisted of foraging and movement with the exception of two pairs, which
utilized restored habitat for breeding. In 2006, five pairs all utilized breeding territories on
narrow habitat slopes, surrounded by golf course greens and cart paths. In 2007 and 2008,
v^l iff^E IX 4821-07
UUUbK 14 October 2008
The Crossings at Carlsbad Holes No. 2 and 3
Emergency Golf Access Path
gnatcatchers have continued to utilize interior golf course habitat slopes for foraging and
breeding.
Research shows that coastal California gnatcatcher uses a variety of plant species that make up
what is commonly referred to as Diegan coastal sage scmb. The assemblages of plant species
that make up any particular patch of coastal sage scmb are largely dependant on site specific
environmental conditions related to soil type and depth, slope, aspect, distance from the coast,
elevation, etc. The coastal Califomia gnatcatcher adapts to and successfully utilizes a wide
variety of coastal sage scmb species compositions, so long as they are not overly dominated by
black sage.
According to DeSimone (1995), shifts in species composition in coastal sage scmb can be seen
in very short distances due to variations in topography, slope aspect, soil type and depth, etc.
Coastal sage scmb is often characterized by a high degree of species patchiness; high cover of a
single species such as Califomia sagebmsh (Artemisia californica), black sage (Salvia mellifera),
or purple sage (Salvia leucophylla).
Nest placement is a function of availability and there does not appear to be a species preference
for nesting so long as the appropriate physical stmcture is present (Ogden 1992). Another smdy
found that Califomia gnatcatcher nests primarily in Califomia sagebmsh (Artemisia californica)
near the coast, but other species are used as well, including Califomia buckwheat (Eriogonum
fasciculatum), black sage, white sage (Salvia apiana), San Diego sunflower (Viguiera laciniata),
coast cholla (Opuntia prolifera), and chemise (Adenostoma fasciculatum). Califomia sagebmsh
is the most important species and the habitat stmcmre may be as important as which plant
species are present (Pacific Southwest Biological Services 1993).
Weaver (1998) determined that climate and soil type greatly influence which species are present
in coastal sage scmb, a widely variable habitat. Other factors, such as slope aspect also play a
role. Califomia sagebmsh is pervasive in most locations. Califomia gnatcatcher frequencies and
densities are greatest on Califomia buckwheat dominated coastal sage scmb with an open or
broken canopy. Coastal sage scmb dominated by Califomia buckwheat is typically found in the
hot inland valleys 12 to 30 miles from the coast, and is found on thin, granodiorite or
metasedimentary rock derived soils. Coastal sage scmb dominated by Califomia sagebmsh and
Califomia encelia have the second highest frequencies and densities of Califomia gnatcatcher.
This subassociation is typically found on marine terraces along the coast and up to eight miles
inland.
What these studies show is that the coastal California gnatcatcher is widely adaptable to
whatever coastal sage scmb habitat is present so long as it has the necessary stmcture to provide
food and shelter.

4.5 Modifications to Buffer Location/SizeA/alue
There are no buffer zones added or lost associated with the removed or added HMP lands.
4.6 Potential Alteration to Drainage Patterns
There are no significant changes to drainage pattems associated with the emergency access path
between Golf Holes No. 2 and 3. The general lay of the land will not be altered by the project
changes and any grading done to prepare the base for paving will be minor. A low concrete curb
will be built on the low side of the access path to catch and direct water mnoff into the golf
course drainage system. Therefore, any additional mnoff created by the impermeable path
surface will not affect the namral hillside.
5.0 CONCLUSIONS
The HMP boundary modifications proposed for the emergency access path between Golf Holes
No. 2 and 3 will have no significant impact on ESHA, as defined by Public Resources Code
Section 30107.5, nor would it have any negative impact on sensitive species such as the coastal
Califomia gnatcatcher. The emergency access path between Golf Holes No. 2 and 3 is consistent
with and in conformance with Public Resources Code Sections 30240 (a) and (b). Therefore, the
laws, regulations, and policies to protect environmentally sensitive species and habitat area are
satisfied, and are in compliance with the Califomia Coastal Act and Carlsbad LCP.
