SUBJECT: Biological Resources Assessment for the Catavina Residential Project in Palm
Desert, Riverside County, California
Dear Kim Molina,
Michael Baker International is pleased to submit this technical report documenting the results of
a biological resources assessment for the proposed Catavina Residential Development Project
(Project or Project site), Assessor Parcel Number (APN) 620-170-009, in Palm Desert, Riverside
County, California. This report is intended to satisfy the requirements of the California
Environmental Quality Act (CEQA) and demonstrate consistency with the Coachella Valley
Multiple Species Habitat Conservation Plan (CVMSHCP).
1.0 PROJECT LOCATION
The 77.8-acre Project site is located south of Interstate 10 within the Coachella Valley region of
Riverside County (Attachment A: Figure 1, Regional Vicinity). The Project site is within the
northwestern portion of the City of Palm Desert, south of Frank Sinatra Drive, west of Portola
Avenue, east of Monterey Avenue, and north of Country Club Drive. The Project straddles the
Cathedral City and Myoma US Geological Survey (USGS) 7.5-minute topographic quadrangle
maps (Attachment A: Figure 2, Project Vicinity). Surrounding land uses include residential
development to the north, south, and west, and a vacant lot to the east between the Project site
and Portola Avenue (Attachment A: Figure 3, Project Area).
The Project site is within the CVMSHCP but is not in a Conservation Area or modeled habitat for
any covered species.
2.0 PROJECT DESCRIPTION
The proposed Project includes development of 546 single- and two-story residences, on-site
circulation, utility infrastructure, stormwater improvements, and open space areas (Attachment A:
Figure 4, Conceptual Site Plan). The Project is divided into four planning areas to allow for a
variety of housing product types. In the northwest portion of the Project site, 88 single-family units
would be developed on 5,000-square-foot lots. The northeast portion of the site would be

developed with 43 six-pack clustered single-family units, for a total of 255 homes on lots ranging
from 2,120 to 2,460 square feet. In the central portion of the site, 103 single-family homes would
be developed on 3,000-square-foot lots. In the southern portion, 100 single-family units would be
developed on 4,050-square-foot lots. Approximately 15.4 acres of common open space would be
distributed throughout the site, and four retention basins are proposed on 2.78 acres.
3.0 EXISTING SITE CONDITIONS
The Project site consists of a disturbed, vacant lot that was previously operated as the Santa
Rosa Country Club Golf Course from approximately 1978 until its closure in 2015. The site is
dominated by ruderal and non-native grasses and does not support any natural vegetation
communities. Elevation on-site is approximately 280 feet above sea level. There are two dried-up
artificial ponds, one in the northern and one in the central portion of the Project site, that are
associated with the former golf course. Existing remnants of a cement cart path, clubhouse, cart
storage structure, and asphalt parking lot are distributed throughout the site. Approximately 1.1
acres in the southeast portion is developed with a cell tower. Perimeter concrete block wall fencing
exists along the site’s northern boundary. The southern and western boundary were fenced with
chain link fence and concrete wall for a portion. The Project’s eastern boundary is partially fenced
but the majority is open.
Soils mapped on-site are depicted in Attachment A: Figure 5, USDA Soils, and are composed of
Myoma fine sand, 0 to 5 percent slopes (MaB), Myoma fine sand, 5 to 15 percent slopes (MaD),
and Water (W) (NRCS 2025).
4.0 METHODS
4.1 Literature Review
Prior to conducting a field survey, Michael Baker conducted a thorough literature review and
records search to characterize existing site conditions and assess the potential for special-status
biological resources to occur that might pose a constraint to Project implementation.1 Queries of
the California Natural Diversity Database (CNDDB; CNDDB 2025) and California Native Plant
Society (CNPS) Online Inventory of Rare and Endangered Plants of California (CNPS 2025) were
conducted to obtain lists of special-status plant and wildlife species occurrence records within the
USGS Seven Palms Valley, East Deception Canyon, Keys View, Cathedral City, Myoma, West
Berdoo Canyon, Rancho Mirage, La Quinta, and Indio 7.5-minute quadrangle maps. The US Fish
and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) online database
was also reviewed to identify special-status species and other resources, such as Critical Habitat,
known or expected to occur on the Project site or within the immediate vicinity (USFWS 2025a).
Other sources of information about the Project and surrounding area include the Natural
Resources Conservation Service’s (NRCS) Web Soil Survey (NRCS 2025) and the USFWS
1 As used in this report, special-status refers to plant and wildlife species that are federal or state-listed, proposed,
or candidates; plant species that have been designated a California Rare Plant Rank by the California Native Plant
Society; wildlife species that are designated by the California Department of Fish and Wildlife as Fully Protected,
or Species of Special Concern; and other state or locally rare vegetation communities.

National Wetlands Inventory (USFWS 2025b). All the information obtained informed Michael
Baker’s understanding of the Project and assisted with the field survey and subsequent analysis.
The results presented in this report provide a detailed assessment of the suitability of the habitat
on-site to support special-status plant and wildlife species and other sensitive natural resources.
4.2 Habitat Assessment/Field Survey
Michael Baker biologists Marisa Flores, Anna Jullie, and Jared McElhany conducted a general
biological resources survey and habitat assessment on January 16, 2025, between 800 and 1200
hours to document existing conditions; conduct a habitat assessment for special-status plant and
wildlife species and sensitive natural communities; and determine the presence of aquatic
resources within the Project site. Weather conditions were sunny and clear with temperatures
ranging from 62 to 85 degrees Fahrenheit and no wind. A total of 78 acres were covered during
the survey.
Classification of the on-site vegetation communities and other land uses is based on the
descriptions of terrestrial vegetation classification systems described in A Manual of California
Vegetation (Sawyer et al. 2009). In addition, site characteristics such as soil condition,
topography, hydrology, anthropogenic disturbances, indicator species, condition of on-site
vegetation communities, and the presence of potentially regulated jurisdictional features were
noted. A formal aquatic resources delineation was not conducted. Michael Baker used geographic
information systems (GIS) software to digitize the mapped vegetation communities and overlaid
the data onto an aerial photograph to further analyze existing conditions and quantify the
acreages of each vegetation community on-site.
All plant and wildlife species observed during the field survey were recorded in a field notebook.
Plant species observed were identified by visual characteristics and morphology in the field while
unusual and less familiar plant species were photographed and later identified using taxonomic
guides. Plant species nomenclature and taxonomy follows The Jepson Manual: Vascular Plants
of California (Baldwin et al. 2012) and scientific names are provided immediately following
common names of plant species (first reference only). Wildlife detections were made through
aural and visual detection, as well as observation of sign including scat, trails, tracks, burrows,
and nests. Field guides used to assist with identification of species during the field survey included
The Sibley Guide to Birds (Sibley 2014) for birds, A Field Guide to Western Reptiles and
Amphibians (Stebbins 2003) for herpetofauna, and A Field Guide to Mammals of North America
(Reid 2006) for mammals. Wildlife species taxonomy follows the North American Butterfly
Association (NABA; NABA n.d.) for butterflies, the Society for the Study of Amphibians and
Reptiles (Crother et al. 2017) for herpetofauna, the American Ornithological Society for birds
(Chesser et al. 2023), and Wilson and Reeder (2005) for mammals. Scientific names are provided
immediately following common names of wildlife species (first reference only).
4.3 Special-Status Species Assessment
The potential for special-status species to occur on the Project site was evaluated based on each
species' known geographic distribution and elevation range; species-specific habitat requirements
(e.g., vegetation communities/land covers, soils, hydrology, slope/aspect, and other
requirements); life history traits (e.g., disturbance tolerance); and Michael Baker biologists’

expertise, knowledge, and best professional judgement. Current and historical records of species
identified during the literature review were also considered during the analysis; however, a
species' potential to occur determination was not solely based on the age or location of these
previously documented records. The potential to occur categories used in this analysis are
defined as follows:
• Present: The species was observed or detected within the study area during the January
16, 2025, survey.
• Expected: The study area is within the known geographic distribution and elevation range
of the species; suitable habitat (considering vegetation, soils, and other factors) is present;
and there is viable landscape connectivity to a local, known extant population(s) or
sighting(s).
• Moderate: The study area is within the known geographic distribution and elevation range
of the species; however, habitat within the study area (considering vegetation, soils, and
other factors) is marginal or limited and landscape connectivity to a local, known, extant
population or detection is compromised or nonexistent.
• Not Expected: The species is not expected to occur within the study area due to the lack
of suitable habitat; the location of the study area is outside of the species' elevation range
or known geographic distribution; or there is no connectivity to known, extant populations.
• Absent: The species was not detected during focused or agency-approved protocol
surveys.
5.0 RESULTS
5.1 Vegetation Communities and Land Covers
The Project site supports the following land cover types: Mediterranean grass grasslands,
developed land, and disturbed land. These are summarized in Table 1, Vegetation Communities
and Land Cover Types, and depicted in Attachment A: Figure 6, Vegetation Communities and
Other Land Uses. No native vegetation communities occur on the Project site. The surrounding
area consists of mixed-use suburban development. A total of 21 species of native or naturalized
plants, 10 native (48 percent) and 11 non-native (52 percent), were recorded on-site. Attachment
B contains photographs of the Project site and Attachment C, Species Compendiums, contains a
list of observed plant species.
Mediterranean Grass Grasslands
Mediterranean grass grasslands, a non-native vegetation type, is located across most of the
Project site. This vegetation type was disturbed and consisted of common Mediterranean grass
(Schismus barbatus) and non-native mustards including Sarahan mustard (Brassica tournefortii)
and London rocket (Sisymbrium irio). A number of shrubs and trees were scattered across the
Project site within this vegetation community, including desert twinbugs (Dicoria canescens),
shrubby tiquilia (Tiquilia canescens), desert broom (Baccharis sarothroides), and river red gum
(Eucalyptus camaldulensis).

Disturbed
The disturbed land cover mapping unit includes the two existing pond areas. This is dominated
mostly by non-native species including Saharan mustard, London rocket, and Spanish needles
(Bidens alba).
Developed
The developed land cover mapping unit consists of the clubhouse, parking lot, and other ancillary
buildings across the Project site. Several ornamental tree species along the site boundaries within
these areas include Chinese banyan (Ficus microcarpa), sweet acacia (Vachellia farnesiana), and
Mexican fan palm (Washingtonia robusta).

5.2 General Floral Inventory
As described in Section 5.1, the Project site primarily supports non-native vegetation, and is
largely dominated by Mediterranean grasslands, London rocket, and Sarahan mustard. The
primary native species observed included fourwing saltbush (Atriplex canescens), cheesebush
(Ambrosia salsola), desert twinbugs, brittlebush (Encelia farinosa), and creosote bush (Larrea
tridentata). The Project site also supports a variety of ornamental trees throughout the site,
including shoestring acacia (Acacia stenophylla), sweet acacia, Chinese banyan, Mexican fan
palm, and river red gum. Attachment C contains a full list of plant species detected on the Project
site.
5.3 General Wildlife Inventory
Eleven wildlife species were observed or detected during the field survey, all of which are native
species: house finch (Haemorhous mexicanus), American crow (Corvus brachyrhynchos),
Costa’s hummingbird (Calypte costae), mourning dove (Zenaida macroura), lesser goldfinch
(Spinus psaltria), verdin (Auriparus flaviceps), greater roadrunner (Geococcyx californianus),
Say’s phoebe (Sayornis saya), coyote (Canis latrans), desert cottontail (Sylvilagus audubonii),

and raccoon (Procyon lotor). Attachment C contains a full list of wildlife species observed or
detected on the Project site.
5.4 Special-Status Biological Resources
Sensitive Natural Communities
One natural community considered sensitive by the California Department of Fish and Wildlife
(CDFW) was reported in the CNDDB from the nine USGS 7.5-minute quadrangle map region:
Desert Fan Palm Oasis Woodland. The study area consists primarily of non-native vegetation and
disturbed and developed land cover types. It does not support native vegetation communities;
therefore, there are no sensitive natural communities present.
Special-Status Plant Species
A total of 36 special-status plant species were reported in the CNDDB and CNPS Online Inventory
of Rare and Endangered Plants of California from the nine USGS 7.5-minute quadrangle map
region. One federally listed endangered plant species, Coachella Valley milk-vetch (Astragalus
lentiginosus var. coachellae), was also recorded in the vicinity by IPaC. After a review of specific
habitat preferences, known distributions, and elevation ranges, no special-status plant species
have the potential to occur on the Project site due to lack of suitable native habitat. Attachment D
contains a summary of special-status species with their potential to occur on the Project site.
The Project site does not fall within any USFWS-designated critical habitat for federally listed
plant species (USFWS 2025a).
The Project site does not fall within CVMSHCP modeled habitat; however, the northeastern
boundary of the site is adjacent to modeled habitat for the Coachella Valley milk-vetch
(Attachment A: Figure 7, CVMSHCP Modeled Habitat).
Special-Status Wildlife Species
A total of 31 special-status wildlife species were reported in the CNDDB from the nine USGS 7.5-
minute quadrangle map region. In addition, monarch (Danaus plexippus) was recorded in the
vicinity by IPaC. No special-status wildlife species were observed during the field survey.
However, seven species have a moderate potential to occur: red-diamond rattlesnake (Crotalus
ruber, CDFW Species of Special Concern [SSC]), coast horned lizard (Phrynosoma blainvillii,
SSC), golden eagle (Aquila chrysaetos, CDFW Fully Protected), burrowing owl (Athene
cunicularia, state candidate endangered [SCE], SSC, CVMSHCP Covered), loggerhead shrike
(Lanius ludovicianus, SSC), vermilion flycatcher (Pyrocephalus rubinus, SSC), and western
yellow bat (Lasiurus xanthinus, SSC). The remaining 24 special-status species are not expected
to occur on the Project site due to a lack of suitable habitat. Attachment D contains a summary of
the special-status species with their potential to occur on the Project site.
The Project site does not fall within any USFWS-designated critical habitat for federally listed
wildlife species (USFWS 2025a).
INTERNATIONAL

The Project site does not fall within CVMSHCP modeled habitat; however, the eastern boundary
of the site is adjacent to modeled habitat for the Coachella Valley giant sand-treader cricket
(Macrobaenetes valgum), Coachella Valley fringe-toed lizard (Uma inornata), flat-tailed horned
lizard (Phrynosoma mcallii), LeConte’s thrasher (Toxostoma lecontei), Coachella Valley round-
tailed ground squirrel (Xerospermophilus tereticaudus chlorus), and Palm Springs pocket mouse
(Perognathus longimembris bangsi) (Attachment A: Figure 7).
State and Federal Jurisdictional Aquatic Features
Three key agencies regulate activities within inland lakes, streams, wetlands, and riparian areas
in California. The US Army Corps of Engineers (USACE) Regulatory Branch regulates activities
that result in the discharge of dredged or fill material into waters of the US, including wetlands,
pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act. Of
the state agencies, the Regional Water Quality Control Board regulates discharges to waters of
the State, including wetlands, pursuant to Section 401 of the Clean Water Act, Section 13263 of
the California Porter-Cologne Water Quality Control Act, State Wetland Definition and Procedures
for Discharges of Dredged or Fill Material to Waters of the State; the CDFW regulates alterations
to lakes, streambeds, and associated riparian habitat pursuant to Section 1600 et seq. of the
California Fish and Game Code (CFGC).
Based on a review of aerial photographs, USGS 7.5-minute quadrangle maps, USFWS National
Wetlands Inventory maps, and observations made during the field survey, there are no drainage
features within and in the immediate vicinity of the Project site that would be considered potentially
jurisdictional. The Whitewater River occurs approximately 1.75 miles south of the site. The
National Wetlands Inventory map shows two freshwater ponds on-site; however, the locations of
these features correspond to the dried-up former golf course ponds. The ponds are human-made,
isolated features that do not support wetland vegetation, hydrology, or soils (Attachment A: Figure
8, National Wetlands Inventory).
The Web Soil Survey shows that the Project site supports Myoma fine sand as listed in Section
3.0, above, and water, which also corresponds to the former golf course ponds (Attachment A:
Figure 5). Soils observed on the Project site were confirmed as fine sands.
5.5 Wildlife Corridors and Habitat Linkages
Wildlife corridors link areas of suitable habitat that are otherwise separated by areas of non-
suitable habitat such as rugged terrain, changes in vegetation, or human disturbance. Wildlife
corridors are essential to the regional ecology of a species because they provide avenues of
genetic exchange and allow animals to access alternative territories as dictated by fluctuating
population densities. Fragmentation of open space areas by urbanization creates “islands” of
wildlife habitat that are more or less isolated from each other. Corridors mitigate the effects of this
fragmentation by (1) allowing animals to move between remaining habitats, thereby permitting
depleted populations to be replenished and promoting genetic exchange; (2) providing escape
routes from fire, predators, and human disturbances, thus reducing the risk of catastrophic events
(such as fire or disease) that could lead to local extinction; and (3) serving as travel routes for
individual animals as they move within their home ranges in search of food, water, mates, and
INTERNATIONAL

Biological Resources Technical Report August 21, 2025
Catavina Residential Development Page 8
shelter. Wildlife corridors are usually bounded by urban land areas or other areas unsuitable for
wildlife. The corridor generally contains suitable cover, food, and/or water to support species and
facilitate movement while in the corridor. Larger, landscape-level corridors (often referred to as
“habitat or landscape linkages”) can provide both transitory and resident habitat for a variety of
species. Although it is commonly used as a synonym for wildlife corridor, a habitat linkage refers
to a more substantial, or wider, land connection between two habitat areas. Habitat linkages allow
for the periodic exchange of animals between habitat areas, which is essential to maintain
adequate gene pools.
The Project site is within a highly developed area of the Coachella Valley in the City of Palm
Desert. Because the Project site is surrounded by development in all directions, it does not serve
as a wildlife corridor or a travel route or linkage to a wildlife corridor. However, because the site
has been abandoned, it may be used periodically by more ubiquitous species that are adapted to
urban areas such as coyote, numerous birds, and common rodents and reptiles.
6.0 IMPACT ANALYSIS
The following discussion examines the impacts to biological resources that may occur as a result
of the proposed Project. The determination of impacts is based on both the features of the
proposed Project and the biological values of the habitat and sensitivity of plant and wildlife
species potentially affected. Impacts to biological resources are assessed using impact
significance threshold criteria, which mirror the policy statement contained in CEQA, Section
21001(c) of the California Public Resources Code. The questions below model those included in
the checklist of questions listed in Appendix G of the CEQA guidelines and that are considered to
determine if the Project would have significant impacts to biological resources.
6.1 Impacts to Special-Status Species
a) Would the project have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or special status species in
local or regional plans, policies, or regulations, or by the California Department of Fish and
Game or U.S. Fish and Wildlife Service?
Less than significant impact. The Project site consists of a former golf course that has been
abandoned and is no longer irrigated or maintained. Some native shrubs have reestablished
themselves over the years; however, the majority of the Project site is dominated by
Mediterranean grasses and non-native mustards.
As detailed in Section 5.4, the Project site does not support suitable habitat for any special-status
plant species. Therefore, the Project would have no impact on special-status plants. Seven
special-status wildlife species have a moderate potential to occur on-site: red-diamond
rattlesnake, coast horned lizard, golden eagle, burrowing owl, loggerhead shrike, vermilion
flycatcher, and western yellow bat.
Burrowing owl and western yellow bat are CVMSHCP-covered species and potential impacts are
addressed in Section 6.6. Golden eagle may be observed foraging over the Project site but would
not be directly impacted by the proposed Project. Loggerhead shrike and vermilion flycatcher may

Biological Resources Technical Report August 21, 2025
Catavina Residential Development Page 9
utilize the site for foraging but are not expected to nest on-site or be present in large numbers due
to the disturbed nature of the site; therefore, potential impacts are considered less than significant.
Lastly, due to the disturbed nature of the Project site and lack of native habitat, red-diamond
rattlesnake and coast horned lizard are not expected to be present in large numbers, if at all;
therefore, potential impacts would not drop regional populations below self-sustaining levels and
are considered less than significant. No mitigation is required for this potential impact.
6.2 Impacts to Sensitive Natural Communities
b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive
natural community identified in local or regional plans, policies, regulations or by the California
Department of Fish and Game or U.S. Fish and Wildlife Service?
No impact. The Project site has been developed since the late 1970s and does not support
riparian habitat or other native vegetation communities. One sensitive natural community, Desert
Fan Palm Oasis, was recorded in the CNDDB from the region; however, this plant community
does not occur on-site. Therefore, no impacts to sensitive plant communities would occur.
6.3 Impacts to State or Federal Wetlands
c) Would the project have a substantial adverse effect on state or federally protected wetlands
(including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling,
hydrological interruption, or other means?
No impact. The Project site has been developed since the late 1970s and does not support any
state or federally protected wetlands. Two dried-up pond features on the Project site are remnant
golf course ponds. The features do not support wetland indicators and no longer retain water.
Therefore, there would be no impact on state or federally protected wetlands.
6.4 Impacts to Wildlife Movement or Wildlife Corridors
d) Would the project interfere substantially with the movement of any native resident or migratory
fish or wildlife species or with established native resident or migratory wildlife corridors, or
impede the use of native wildlife nursery sites?
Less than significant with mitigation. The Project site is highly disturbed and surrounded on
all sides by existing development and disturbance. The Project site has no connectivity to any
natural habitats that would serve as migration corridors, nor do adjacent areas. There would be
no impact to native wildlife movement or wildlife corridors.
Nesting birds are protected pursuant to the federal Migratory Bird Treaty Act (MBTA) of 1918 and

otherwise provided by CFGC or any regulation made pursuant thereto; Section 3503.5 makes it unlawful to take,

Michael Baker
Biological Resources Technical Report August 21, 2025
Catavina Residential Development Page 10
required during the breeding season (generally February 1 to August 31 but as early as January
1 for raptors) prior to any ground disturbance or vegetation removal activities to avoid direct and
indirect impacts to active bird nests and/or nesting birds. Consequently, if an active bird nest is
destroyed or if Project activities result in indirect impacts to nesting birds (e.g., nest abandonment,
loss of reproductive effort), it is considered “take” and is potentially punishable by fines and/or
imprisonment. Although no nests were observed during the field survey, the vegetation within and
adjacent to the Project site provides suitable nesting opportunities for a variety of bird species.
Disturbing or destroying active nests is a violation of the MBTA. In addition, nests and eggs are
protected under CFGC Section 3503. The removal of vegetation supporting an active nest during
the breeding season is considered a potentially significant impact. Mitigation Measure BIO-1
would reduce this impact to a less than significant level.
The unmaintained palm trees around the perimeter of the Project site have the potential to support
maternity colonies of foliar roosting bats within the palm skirts (i.e., dead hanging fronds). The
removal or trimming of trees supporting maternity roosts within the maternity season (March 1
through September 30) is a potentially significant impact. Tree removal and trimming may occur
outside of the bat maternity season (October 1 through February 28). Implementation of
Mitigation Measure BIO-2 would reduce this impact to less than significant.
6.5 Conflicts with Local Policies or Ordinances
e) Would the project conflict with any local policies or ordinances protecting biological resources,
such as a tree preservation policy or ordinance?
No impact. The City of Palm Desert does not have a policy or ordinance protecting biological
resources such as a tree preservation policy or ordinance. Therefore, there would be no conflict
and no impact would occur.
6.6 Conflicts with Adopted Habitat Conservation Plan
f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional, or state habitat conservation
plan?
Less than significant with mitigation. The Project site is within the CVMSHCP but is not in a
Conservation Area. The Project site is also not within CVMSHCP modeled habitat for covered
species; however, modeled habitat is adjacent to the eastern boundary. There is a moderate
potential for two CVMSHCP-covered species, burrowing owl and western yellow bat, to occur on-
site and be impacted by the Project.
possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds-of-prey); and Section 3513 makes
it unlawful to take or possess any migratory non-game bird except as provided by the rules and regulations adopted
by the Secretary of the Interior under provisions of the MBTA, as amended (16 U.S.C. § 703 et seq).
INTERNATIONAL
Michael Baker
Biological Resources Technical Report August 21, 2025
Catavina Residential Development Page 11
According to Section 5.2.1.1 of the CVMSHCP, payment of the Local Development Mitigation Fee
(LDMF) is required for MSHCP compliance and will be included by the city as a condition of project
approval. The current rate, last updated by the Coachella Valley Conservation Commission on
July 1, 2025, is $1,720 per dwelling unit for residential projects with a density of 0-8 units per acre.
There is a potential for two covered species to occur on the project site: western yellow bat and
burrowing owl. Impacts on a maternity roost for western yellow bat may be considered a significant
impact. Mitigation Measure BIO-2 would avoid impacts on bat species during project
construction; therefore, impacts are considered less than significant. Although previously
developed, the Project site could be used by burrowing owl. Although there were no suitable
burrow structures observed that could support this species, due to the presence of suitable
foraging habitat and potential for burrowing owls to occupy the project site between the time the
habitat assessment was conducted and project implementation, impacts to burrowing owl are
considered potentially significant. Mitigation Measure BIO-3 would ensure there are no direct
impacts on burrowing owl and would reduce this impact to less than significant.
7.0 MITIGATION MEASURES
• BIO-1: Within three days prior to ground-disturbing activities associated with Project
implementation that would occur during the nesting/breeding season of native bird species
potentially nesting on the site (typically February 1 through August 31 in the Project region,
or as determined by a qualified biologist), a nesting bird survey will be conducted by a
qualified biologist to determine if active nests protected by the Migratory Bird Treaty Act
and/or the California Fish and Game Code are present and could be potentially directly or
indirectly impacted by the proposed Project. If active nests are found, clearing and
construction within 100 feet of the nest (300 feet for raptors) shall be postponed or halted
at the discretion of the biologist, or until the biologist has confirmed the nest is vacated
and juveniles have fledged.
• BIO-2: To the greatest extent practicable, tree trimming and removal activities shall be
performed outside of the bat maternity season, i.e., October 1 through February 28, to
avoid direct impacts to nonvolant (flightless) young bats that may roost in trees. If tree
removal and trimming occur during the maternity season, which is March 1 through
September 30, a preconstruction bat survey shall be conducted by a qualified biologist
within seven days prior to these activities. Each potentially suitable tree shall be closely
inspected by a qualified biologist to determine the presence of maternity roosts. If bats are
not detected, the tree(s) may be removed in the presence of a qualified biological monitor.
If bats are detected, the occupied tree(s) shall be left in place and an appropriate buffer
(as determined by the qualified biologist) shall be placed around the tree until the end of
the maternity season or until otherwise directed by the qualified biologist.
• BIO-3: Within 30 days prior to any ground disturbing activities, a burrowing owl
preconstruction survey shall be conducted by a qualified biologist to determine the
INTERNATIONAL
Michael Baker
Biological Resources Technical Report August 21, 2025
Catavina Residential Development Page 12
presence/absence of burrowing owls on the project site and within a 500-foot buffer.
Walking transects will be spaced no greater than 30 meters apart to ensure 100 percent
visual coverage of the survey area. The location of all burrowing owls or burrows with
burrowing owl sign shall be recorded and mapped. A written report documenting the
survey shall be prepared following the survey. If burrowing owl individuals or burrowing
owl sign are detected during the preconstruction survey, then CDFW shall be notified to
discuss appropriate avoidance measures. If avoidance is not feasible, a Burrowing Owl
Mitigation and Monitoring Plan (BOMMP) shall be developed to ensure there are no direct
impacts on burrowing owl. The BOMMP shall be approved by CDFW prior to project
implementation.
