EXECUTIVE SUMMARY
LSA was retained by CM Wave Development, LLC to prepare a Biological Resources Assessment and
to conduct a Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) Consistency
Analysis. This report has been prepared for compliance with the California Environmental Quality
Act, the CVMSHCP, and the Federal and California Endangered Species Acts.
The study area lies within the planning boundaries of the CVMSHCP. The CVMSHCP provides take
coverage for covered species, which include both listed and non -listed species that are adequately
conserved by the CVMSHCP. To ensure adequate conservation of covered species, CVMSHCP
Conservation Areas provide habitat and other ecological elements. The study area does not lie
within a CVMSHCP Conservation Area.
The study area contains suitable habitat for the burrowing owl (Athene cunicularia hypugaea) and
other nesting birds protected by the Migratory Bird Treaty Act and the California Fish and Game
Code. A burrowing owl pre -construction survey will be required to ensure any direct impacts to this
species will be avoided. In addition, it is recommended that vegetation removal be conducted
between September 1 and January 15 (outside the general bird nesting season) to avoid impacts to
nesting birds. If vegetation cannot be removed outside the bird nesting season, a pre -construction
nesting bird survey by a qualified biologist is required prior to vegetation removal.
The study area contains suitable roosting and foraging habitat for multiple bat species. Suitable
roosting sites are present in native and non-native ornamental palms, rock outcrops associated with
Coral Mountain, and an abandoned adobe structure. Roosting bats were confirmed in the rock
outcrops during early -maternity season surveys performed in April 2021. Additional maternity -
season surveys will be performed in June 2021 to maximize the probability of detection of maternity
roosts for all bat species that may occur in the proposed project area and to gather more precise
data on numbers and species of bats in roosts identified during the April 2021 survey. If maternity
roosts are identified within the project area, the biologist will coordinate with the California
Department of Fish and Wildlife (CDFW) to implement avoidance measures during the bat maternity
season in accordance with CDFW's established standards. With implementation of this and other
mitigation measures, impacts to roosting bats will be less than significant.
At least one year prior to construction, a qualified bat biologist will conduct a habitat assessment
and acoustic surveys for roosting bats. If maternity roosts or hibernacula are found, the biologist will
coordinate with CDFW to implement avoidance measures where possible. If avoidance of the
roost(s) is not feasible, the biologist will prepare a site-specific bat avoidance and mitigation plan
and coordinate with CDFW. This avoidance and mitigation plan would include mitigation strategies
to minimize and/or mitigate adverse effects to bats, post -implementation monitoring, and
performance standards.
No potential jurisdictional waters regulated pursuant to the Federal Clean Water Act by the U.S.
Army Corps of Engineers or the Regional Water Quality Control Board, and no lake, rivers, or
streambeds regulated pursuant to the California Fish and Game Code by CDFW are present within
the study area.

INTRODUCTION
LSA was retained by CM Wave Development, LLC to prepare a Biological Resources Assessment and
Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) Consistency Analysis. This
report evaluates the approximately 385 -acre proposed Wave at Coral Mountain Development
Project (project) located in the City of La Quinta, Riverside County, California. Specifically, the
project lies south of 58th Avenue and directly west of Madison Street. The project study area is
depicted on the United States Geological Survey (USGS) La Quinta, Indio, Martinez Mountain, and
Valerie, California 7.5 -minute topographic quadrangles in Sections 27 and 28, Township 6 South,
Range 7 East (Figure 1).
PROJECT DESCRIPTION
The project proposes mixed-use residential, resort, and recreational development.
METHODS
Literature Review
A literature review was conducted to assist in determining the existence or potential occurrence of
special-interest plant and animal species within the study area and in the project vicinity. A records
search of the California Department of Fish and Wildlife (CDFW) Natural Diversity Data Base (NDDB)
Rarefind 5 (2019), and California Native Plant Society's Online Inventory of Rare and Endangered
Plants (California Native Plant Society [CNPS] v7-18) for the La Quinta, Indio, Martinez Mountain,
and Valerie, California USGS 7.5 -minute quadrangles was conducted on August 16, 2019.
Additionally a subsequent literature search was conducted on April 27, 2021. A review of the Final
Recirculated CVMSHCP (CVAG 2007) was also conducted in order to determine CVMSHCP
consistency and conservation measures that apply to the proposed project, and to reference
vegetation types within the study area. Geographic Information System software was used to map
the project location, habitat types, land uses, etc.
Field Surveys
LSA Biologist Jodi Ross -Borrego conducted a general field survey within the study area on
September 11, 2019, from 8:00 am to 1:35 pm. Weather conditions consisted of clear skies,
temperatures ranging from 73 to 91 degrees Fahrenheit, and winds ranging from 3 to 5 miles per
hour. Additionally, a follow up general biological field survey was conducted on April 28, 2021 from
6:00 am to 12:40 p.m. Weather conditions consisted of clear skies, temperatures ranging from 58 to
89 degrees Fahrenheit, and winds ranging from 3 to 5 miles per hour. The entire study area was
surveyed on foot. Notes were taken on general site conditions, vegetation, and suitability of habitat
for various special-interest elements.
A bat habitat assessment was performed in November 2020 by LSA bat specialist Jill Carpenter, and
focused nighttime acoustic and emergence surveys were conducted by LSA biologists in April 2021.
The detailed results of the focused bat surveys are provided in a separate report. All plant and
animal species observed or otherwise detected during all field surveys were noted and are listed in
Appendix A. Appendix B summarizes the special-interest plant and animal species potentially
present within the study area.

RESULTS
Existing Site Conditions
The study area is south of 58th Avenue and west of Madison Street. Other surrounding land uses
include residential development to the north and east, vacant land to the west, and settling ponds
to the south. The project falls within the boundaries of the CVMSHCP, as discussed in further detail
below.
Topography and Soils
The study area is situated on relatively flat land within elevations ranging from approximately 72
feet below mean sea level to 65 feet above mean sea level.
A mosaic of soils occurs within the study area and is mapped by the Soil Conservation Service
(Knecht 1980) as the following types:
• CdC: Carsitas gravelly sand, 0 to 9 percent slopes;
• CpA: Coachella fine sand, 0 to 2 percent slopes;
• CsA: Coachella fine sand, 0 to 2 percent slopes;
• GaB: Gilman loamy fine sand, 0 to 5 percent slopes;
• GbA: Gilman find sandy loam, 0 to 2 percent slopes;
• Ip: Indio fine sandy loam;
• Ir: Indio fine sandy loam, wet;
• Is: Indio very fine sandy loam;
• It: Indio very fine sandy loam, wet;
• MaB: Myoma fine sand, 0 to 5 percent slopes; and
• RO: Rock outcrop.
Vegetation
Vegetation within the study area is best described as Desert Saltbush scrub, Tamarisk scrub, and
Mesquite Hummock (CVMSHCP 2007). Land is disturbed in southern and northeast portions of the
study area and a stand of blue palo verde (Parkinsonia florida) is present in the eastern portion of
the study area. Dominant species include fourwind saltbush (Atriplex canescens), bush seepweed
(Suaeda nigra), athel (Tamarix aphylla), and common Mediterranean grass (Schismus barbatus).
The majority of the study area was previously agricultural land. As a result, the Desert Saltbush
scrub is fairly disturbed throughout the study area.

Wildlife
Common wildlife species observed within the study area during the field survey include common
raven (Corvus corax), mourning dove (Zenaida macroura), house finch (Haemorhous mexicanus),
and greater roadrunner (Geococcyx californianus).
Figure 2 shows vegetation and photograph key locations. Figure 3 shows site photographs. A
complete list of plant and wildlife species observed is provided in Appendix A.
Coachella Valley Multiple Species Habitat Conservation Plan
The CVMSHCP is a comprehensive, multi -jurisdictional habitat conservation plan focusing on
conservation of species and their associated habitats in the Coachella Valley region of Riverside
County. The overall goal of the CVMSHCP is to maintain and enhance biological diversity and
ecosystem processes within the region, while allowing for future economic growth. The CVMSHCP
covers 27 sensitive plant and wildlife species (Covered Species) as well as 27 natural communities.
Covered Species include both listed and non -listed species that are adequately conserved by the
CVMSHCP. The overall provisions for the plan are subdivided according to specific resource
conservation goals that have been organized according to geographic areas defined as Conservation
Areas.
The proposed project is within the boundaries of the CVMSHCP; however, it is not within any
conservation areas identified in the CVMSHCP.
Special -Status Species
This section discusses special -status species observed or potentially occurring within the limits of the
study area. Legal protection for special-interest species varies widely, from the comprehensive
protection extended to listed threatened/endangered species, to no legal interest at present. The
CDFW, U.S. Fish and Wildlife Service (USFWS), local agencies, and special-interest groups, such as
the CNPS, publish watch lists of declining species. Species on watch lists can be included as part of
the special-interest species assessment. Species that are candidates for State and/or Federal listing
and species on watch lists are included in the special-interest species list. Inclusion of species
described in the special-interest species analysis is based on the following criteria:
• Direct observation of the species or its sign in the study area or immediate vicinity during
previous biological studies;
• Sighting by other qualified observers;
• Record reported by the NDDB, published by the CDFW;
• Presence or location information for specific species provided by private groups (e.g., CNPS);
and/or
• Study area lies within known distribution of a given species and contains appropriate habitat.

The special-interest species analysis revealed 49 special-interest species with the potential to occur
within the limits of the study area. Appendix B lists these species with a data summary and
determination of the likelihood of each species occurring within the study area.
Threatened/Endangered Species
The following seven federally/State listed species were identified as potentially present (Appendix B)
in the project vicinity:
• Coachella Valley milkvetch (Astragalus lentiginosus var. coachellae [CVMV]): Federally listed as
Endangered and CVMSHCP covered species;
• Triple -ribbed milkvetch (Astragalus tricarinatus): Federally listed as Endangered and CVMSHCP
covered species;
• Casey's June beetle (Dinacoma caseyi): Federally listed as Endangered;
• Desert pupfish (Cyprinodon macularius): Federally and State -listed as Endangered and CVMSHCP
covered species;
• Desert slender salamander (Batrachoseps major aridus) Federally and State -listed as
Endangered;
• Coachella Valley fringe -toed lizard (Uma inornata): Federally listed as Threatened, State listed as
Endangered, and CVMSHCP covered species; and
• Peninsular bighorn sheep (Ovis Canadensis nelsonii) (peninsular Distinct Population Segment):
Federally listed as Endangered, State listed as threatened, California Fully Protected Species, and
CVMSHCP covered species.
Habitat within the study area is considered unsuitable for six of the seven species identified above.
Marginally suitable habitat for CVMV was found to be present within the study area.
Non -Listed Special -Interest Species
Of the 42 other non -listed special-interest species identified and discussed in Appendix B, 18 species
are considered absent based on lack of suitable habitat, seven species are considered to have a low
probability of occurrence, seven species are considered to have a moderate probability of
occurrence, five species are considered to have a high probability of occurrence, and five species
were detected within the study area during field surveys. The following non -listed special-interest
species have a moderate to high probability to occur, or were detected, within the study area:
• Slender cottonheads (Nemacaulis denudata var gracilis);
• Flat -tailed horned lizard (Phryosoma macalli);
• Burrowing owl (Athene cunicularia);
• Ferruginous hawk (Buteo regalis);
• Prairie falcon (Falco mexicanus);
• Black -tailed gnatcatcher (Polioptila melanura);

• Le Conte's thrasher (Toxostoma lecontei);
• California leaf -nosed bat (Macrotus californicus);
• Western yellow bat (Lasiurus xanthinus);
• Yuma myotis (Myotis yumanensis);
• Pallid bat (Antrozous pallidus);
• Western mastiff bat (Eumops perotis);
• Pocketed free -tailed bat (Nyctinomops femorosaccus);
• Big free -tailed bat (Nyctinomops macrotis);
• Pallid San Diego pocket mouse (Chaetodipus fallax pallidus); and
• Palm Springs round -tailed ground squirrel (Xerospermophilus tereticaudus chlorus).
Nesting bird species, including special-interest species identified in Appendix B, with potential to
occur are protected by California Fish and Game Code Sections 3503, 3503.5, and 3800, and by the
Migratory Bird Treaty Act (MBTA) (16 USC 703-711). These laws regulate the take, possession, or
destruction of the nest or eggs of any migratory bird or bird of prey. However, the USFWS has
recently determined that the MBTA should apply only to "... affirmative actions that have as their
purpose the taking or killing of migratory birds, their nests, or their eggs" and will not be applied to
incidental take of migratory birds pursuant to otherwise lawful activities.
Critical Habitat
The study area does not lie within federally designated critical habitat.
Jurisdictional Waters
No potential jurisdictional waters regulated pursuant to the Federal Clean Water Act (CWA) by the
U.S. Army Corps of Engineers (USACE) or the Regional Water Quality Control Board (RWQCB), and no
lake, rivers, or streambeds regulated pursuant to the California Fish and Game Code by the CDFW
are present within the limits of the proposed project.
IMPACTS AND RECOMMENDATIONS
Following is a discussion of potential disturbances and recommendations for avoidance,
minimization, and mitigation measures per applicable local, State, and Federal policy.
Threatened and Endangered Species
Coachella Valley Milkvetch
CVMV is a covered species under the CVMSHCP. The CVMSHCP does not require avoidance and
minimization measures for CVMV. Through participation in the CVMSHCP via payment of
development fees, the project would mitigate for any impacts to CVMV.

WAVE AT CORAL MOUNTAIN DEVELOPMENT PROJECT C A
CITY OF LA QUINTA, CALIFORNIA J At`
Non -Listed Special -Interest Species
The 42 special-interest species identified in Appendix B as having a low to high probability of
occurrence in the study area have limited population distribution in Southern California and
development is further reducing their ranges and numbers. These species have no official State or
Federal protection status, but they merit consideration under the California Environmental Quality
Act (CEQA). Due to the disturbed nature of the site, surrounding development, and through
compliance with the CVMSHCP, impacts from the project are anticipated to have a less than
significant effect on these non -listed special-interest species.
In addition, to ensure compliance with California Fish and Game Code and to avoid potential impacts
to nesting birds, it is recommended that the vegetation removal activities be conducted outside the
general bird nesting season (January 15 through August 31). If vegetation cannot be removed
outside the bird nesting season, a pre -construction nesting bird survey by a qualified biologist is
required prior to vegetation removal.
Burrowing Owl
A pre -construction burrowing owl survey would be required using an accepted protocol (as
determined by the Coachella Valley Conservation Commission in coordination with the permittees
and the wildlife agencies). Prior to construction, a qualified biologist will survey the construction
area and, as feasible, up to a 500 -foot buffer outside the project limits for burrows that could be
used by burrowing owl. If a burrow is located, the biologist will determine whether an owl is present
in the burrow. If the burrow is determined to be occupied, the burrow will be flagged and a 160 -foot
diameter buffer will be established during the non -breeding season or a 250 -foot diameter buffer
during the breeding season. The buffer area will be staked and flagged. No development activities
will be permitted within the buffer until the young are no longer dependent on the burrow.
Bats
Early season nighttime acoustic and emergence surveys in April 2021 confirmed the presence of at
least eight bat species, including four with special status, within the study area. Additional
maternity -season surveys will be performed in June 2021 to maximize the probability of detection of
maternity roosts, which are native wildlife nursery sites, for all bat species that may occur in the
proposed project area and to gather more precise data on numbers and species of bats in roosts
identified during the April 2021 survey. If maternity roosts are identified within the project area, the
biologist will coordinate with the CDFW to implement avoidance measures during the bat maternity
season in accordance with CDFW's established standards. No construction will occur within a 300 -
foot buffer of maternity roost sites during the bat maternity season unless concurrence is received
from CDFW to reduce that buffer distance based upon the bat species present and the activities
occurring. Other mitigation measures include two-step tree removal protocols, minimization of light
overspill, and humane bat exclusion.
Critical Habitat
No federally designated critical habitat is present within the study area; therefore, there will be no
project -related effects to critical habitat.

CITY OF LA QUINTA, CALIFORNIA J At`
Jurisdictional Waters
No potential jurisdictional waters of the United States regulated by the USACE or RWQCB, or CDFW
jurisdictional lakes, rivers, or streams are present on the proposed project site. Thus, there will be
no project -related effects to jurisdictional waters.
Habitat Fragmentation and Wildlife Movement
Wildlife movement and habitat fragmentation are important issues in assessing effects 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.
Isolation of habitat occurs when wildlife cannot move freely from one portion of the habitat to
another or from one habitat type to another. An example is the fragmentation of habitats within
and around "checkerboard" residential development. Habitat fragmentation can also occur when a
portion of one or more habitats is converted into another habitat, as when scrub habitats are
converted into annual grassland habitat because of frequent burning.
Because the study area does not lie within a CVMSHCP-designated wildlife corridor and the study
area is adjacent to residential development, the proposed project is not anticipated to have
significant impacts related to habitat fragmentation and regional wildlife movement.
Local Policies and Ordinances
With participation in the CVMSHCP, the project would not conflict with any local policies or
ordinances.
Coachella Valley Multiple Species Habitat Conservation Plan
The study area lies within the planning area of the CVMSHCP; however, it does not lie within a
Conservation Area identified in the CVMSHCP. The proposed project is subject to the requirements
of the CVMSHCP (e.g., development fees).
MITIGATION MEASURES
BIO -1: A burrowing owl clearance survey shall be performed by a qualified biologist not more than
30 days prior to any site disturbance (grubbing, grading, and construction). The pre -construction
survey is required to use accepted protocol (as determined CDFW). Prior to construction, a qualified
biologist will survey the construction area and an area up to a 500 -feet outside the project limits for
burrows that could be used by burrowing owls. lithe burrow is determined to be occupied, the burrow
will be flagged, and a 160 -foot diameter buffer will be established during non -breeding season or a
250 -foot diameter buffer during the breeding season. The buffer area will be staked and flagged. No
development activities will be permitted within the buffer until the young are no longer dependent
on the burrow.
If the burrow is unoccupied, the burrow will be made inaccessible to owls, and construction may
proceed. If either a nesting or escape burrow is occupied, owls shall be relocated pursuant to accepted
Wildlife Agency protocols. A burrow is assumed occupied if records indicate that, based on surveys
conducted following protocol, at least one burrowing owl has been observed occupying a burrow on

site during the past three years. If there are no records for the site, surveys must be conducted to
determine, prior to construction, if burrowing owls are present. Determination of the appropriate
method of relocation, such as eviction/passive relocation or active relocation, shall be based on the
specific site conditions (e.g., distance to nearest suitable habitat and presence of burrows within that
habitat) in coordination with the Wildlife Agencies. Active relocation and eviction/passive relocation
require the preservation and maintenance of suitable burrowing owl habitat determined through
coordination with the Wildlife Agencies.
BIO -2: In June 2021, a qualified bat biologist will conduct a second round of focused nighttime surveys
for roosting bats at locations where suitable roosting habitat is identified. The nighttime survey will
include a combination of acoustic and exit count methods, and will take place during the bat maternity
season (March 15—August 31 in the Coachella Valley) to enable detection of maternity -roosting bats.
If maternity roosts are identified within the project area, the biologist will coordinate with CDFW to
implement avoidance measures during the bat maternity season in accordance with CDFW's
established standards. No construction activities will occur within a 300 -foot buffer of maternity roost
sites during the bat maternity season unless concurrence is received from CDFW to reduce that buffer
distance based upon the bat species present and the activities occurring.
BIO -3: Removal of trees (including palm trees) shall occur outside the maternity season (March 15—
August 31 in the Coachella Valley), which coincides with the bird nesting season, to avoid the potential
for "take" of nonvolant (flightless) young. Trees and snags that have been identified as confirmed or
potential roost sites require a two-step removal process and the involvement of a bat biologist to
ensure that no roosting bats are killed during this activity. Consistent with CDFW protocols this two-
step removal shall occur over two consecutive days as follows: on Day 1, branches and limbs not
containing cavities, as identified by a qualified bat biologist, will be removed. On Day 2, the remainder
of the tree may be removed without supervision by a bat biologist. The disturbance caused by limb
removal, followed by an interval of one evening, will allow bats to safely abandon the roost.
BIO -4: Although no construction will occur at the rock outcrops where occupied bat roosts were
identified during the April 2021 surveys, bats roosting in that area could be subject to potential
adverse effects from project -related light overspill. To avoid permanent impacts to roosting bats from
the installation of new light fixtures associated with the proposed development, all lighting fixtures
shall have light shields or similar devices (e.g., dark sky compliant lighting) installed to minimize light
overspill on to Coral Mountain and surrounding open space.
BIO -5: A qualified bat biologist shall confirm the absence of roosting bats prior to any removal of the
adobe. If bats are found or if the absence of bats cannot be confirmed, the bat biologist will install or
directly supervise installation of humane eviction devices and exclusionary material to prevent bats
from roosting in the building. Implementation of the humane eviction/exclusions is typically
performed in the fall (September or October) preceding construction activity at each structure to
avoid impacts to hibernating bats during the winter months or during the maternity season (March
15—August 31 in the Coachella Valley), when nonvolant (flightless) young are present. Any humane
eviction/exclusion devices must be installed at least 10 days prior to the demolition of a structure
housing bats to allow sufficient time for the bats to vacate the roost(s).

BIO -6: To ensure compliance with California Fish and Game Code and the MBTA and to avoid
potential impacts to nesting birds, vegetation removal activities shall be conducted outside the
general bird nesting season (January 15 through August 31). Any vegetation removal and/or
construction activities that occur during the nesting season will require that all suitable habitats be
thoroughly surveyed for the presence of nesting birds by a qualified biologist. Prior to commencement
of clearing, a qualified biologist shall conduct preconstruction surveys within 14 days and repeated 3
days prior to ground -disturbing activities. . If any active nests are detected a buffer of 300 feet (500
feet for raptors) around the nest adjacent to construction will be delineated, flagged, and avoided
until the nesting cycle is complete. The buffer may be modified and/or other recommendations
proposed as determined appropriate by the biologist to minimize impacts.
CUMULATIVE IMPACTS
According to Section 15130 of the CEQA Guidelines, "cumulative impacts" refers to incremental
effects of an individual project when viewed in connection with the effects of past projects, current
projects, and probable future projects. Due to the relatively disturbed nature of the study area, its
proximity to residential development, and through compliance with the CVMSHCP, impacts are not
considered to be cumulatively significant.
