6 Diesel particulate matter was used as a surrogate for estimating cancer risk and chronic health impacts of diesel vehicle exhaust.
7 Speciated diesel exhaust emissions were used only for estimating acute health impacts of diesel vehicle exhaust. 8 Naphthalene and POM have only cancer and chronic impacts. Since DPM was used as a surrogate for estimating cancer and chronic impacts of diesel vehicle exhaust, naphthalene and POM emissions from diesel-fueled vehicles were not used to estimate health impacts in this health risk assessment.

CAMARILLO COSTCO PROJECT

BIOLOGICAL RESOURCES ASSESSMENT

CAMARILLO, CA
____________________________________________________________________________

SUMMARY
A due diligence biological resources assessment was performed for the proposed Camarillo Costco Project (Project) by Kleinfelder biologists Terry Hurt and Lisa Achter. The proposed Project entails construction of a new Costco Wholesale Warehouse, gas station, and associated parking lot on approximately 20.18 acres of a 27.12-acre parcel (APN 230-002-025) (Figure 1).

Ms. Achter conducted a preliminary desktop review of the site and Mr. Hurt performed a field verification survey to identify and characterize existing on-site biological resources and determine the potential for resources considered to be special-status by state and federal resource agencies to occur on the site. The field survey included the parcel described above (Project area), including an area of potential effect (APE) buffer extending 50 feet around the Project area. The Project area and the APE together comprise the study area.

Based on the results of the desktop review and field verification survey, one special-status wildlife species, burrowing owl (Athene cunicularia), was determined to have a moderate potential to occur within the study area and no special-status plant species were determined to have a moderate or greater potential to occur within the study area. No special-status plant or wildlife species were observed during the field survey.

This report serves to document the methods and results of the April 25, 2022, biological field survey, describes potential biological resource constraints associated with development of the site, and provides recommendations to address these constraints. 20230187.001A/LH22R140891 Page 2 of 11 May 26, 2022

1 INTRODUCTION

1.1 Objectives
The purpose of this analysis is to evaluate the study area to assess the potential for special-status plant and wildlife species and sensitive natural communities to occur at the Project site, and the potential effects to these biological resources due to Project construction. This assessment provides the methods and results of the field survey, including vegetation communities and land cover types present within the study area, special-status plant and wildlife species detected or determined to have potential to occur within the study area, the presence of wildlife movement corridors or federally designated Critical Habitat within or adjacent to the study area, and any additional focused surveys necessary to further evaluate potential impacts to biological resources at the Project site. Recommendations to avoid and minimize impacts to these resources are also provided in Section 4 of this document.

1.2 Project Location
The approximately 27.12-acre parcel is located in City of Camarillo in Ventura County, California (Figure 1). The site is bounded by U.S. Highway 101 on the north, a Home Depot shopping center on the east, West Ventura Boulevard on the south (and Camarillo Airport south of West Ventura Boulevard), and Springfield Drive and an undeveloped parcel on the west (Figure 2). The Project parcel is undeveloped in an otherwise mostly developed residential and industrial area of Ventura County. The study area is flat, with elevations remaining constant between approximately 72-87 feet above mean sea level. Adjacent land uses are primarily urban and residential, although there are undeveloped parcels similar in composition to the Project area to the west and northwest (Figure 2). There are no structures within the study area. The Project plans are depicted in Figure 3.

The study area is situated within the 7.5-minute U.S. Geological Survey (USGS) Camarillo quadrangle within the Rio de Santa Clara Land Grant. The corresponding latitude and longitude at the approximate center of Project area is 34°13'06" north latitude and 119°04'56" west longitude.

2 METHODS

2.1 Desktop Review
Special-status plant and wildlife species present or potentially present within or adjacent to the study area were identified through a desktop literature review using the following sources: U.S.

Fish and Wildlife Service (USFWS) Information, Planning, and Consultation (IPaC) Trust Resource Report; California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB); and the California Native Plant Society (CNPS) Online Inventory of Rare and Endangered Vascular Plants. Additionally, the Natural Resources Conservation Service (NRCS), Web Soil Survey (WSS) was queried to determine soil types that exist within the boundary of the study area (USDA 2022), as well as the USFWS National Wetlands Inventory (NWI) database (USFWS 2022a). The CNDDB and CNPS database searches included the 7.5-minute USGS Camarillo quadrangle and the IPaC search included the study area and a two-mile buffer surrounding the site. Special-status species include those that are considered threatened, endangered, candidate for listing, species of special concern or fully protected by CDFW, USFWS, or CNPS. California Rare Plant Rank (CRPR) 1 and 2 plant species were included in the CNPS search. Following a review of these resources, Kleinfelder also reviewed relevant life history information on those species documented as occurring in the region, including habitat type, soils, and elevation preferences.

2.2 Definition of Special-Status Species
Although threatened and endangered species are protected by specific federal and state statutes, California Environmental Quality Act (CEQA) Guidelines Section 15380(b) provides that a species not listed on the federal or state list of protected species may be considered rare or endangered if the species can be shown to meet certain criteria. These criteria have been modeled after the definition in the federal Endangered Species Act (FESA) and the section of the California Fish and Game Code dealing with rare or endangered plants and animals, and allows a public agency to undertake a review to determine if a significant effect on a species that has not yet been listed by either the USFWS or CDFW (i.e., species of special concern) would occur. Whether a species is rare, threatened, or endangered can be legally significant because, under CEQA Guidelines, Section 15065, an agency must find an impact to be significant if a project would “substantially reduce the number or restrict the range of an endangered, rare, or threatened 20230187.001A/LH22R140891 Page 4 of 11 May 26, 2022
© 2022 Kleinfelder www.kleinfelder.com
species.” Thus, CEQA provides an agency with the ability to protect a species from a project’s potential impacts until the respective government agencies have an opportunity to designate the species as protected, if warranted.

2.2.1 Special-Status Wildlife Species
Special-status wildlife species include taxa designated as follows:
 Threatened, endangered, or candidate for listing under FESA;  Threatened, endangered, or rare under the California Endangered Species Act (CESA);
 CDFW species of special concern or fully protected species.

2.2.2 Special-Status Plant Species
Special-status plant species include taxa designated as follows:
 Threatened, endangered, or candidate for listing under the FESA;  Threatened, endangered, or rare under the CESA;
 Species with CRPRs as described below (CNPS 2022):
 1A – Plants presumed extinct in California
 1B – Plants considered rare, threatened, or endangered in California and elsewhere.
 2 – Plants considered rare, threatened, or endangered in California, but more common elsewhere.

2.3 Field Surveys
A field survey was performed by Kleinfelder biologist Terry Hurt on April 25, 2022, to evaluate botanical and wildlife resources within the study area, including habitat suitability for special-status species.

The survey consisted of walking through the Project area and along its periphery, where possible, to map and characterize vegetation communities, collect data on the relative quality of, and potential for, existing habitats to support the special-status species identified during the preliminary database and resources review, and to identify any other sensitive biological resources present or potentially present within the site. An aerial photograph (Google Earth 2022) and georeferenced mobile map with an overlay of the Project boundary was utilized to map 20230187.001A/LH22R140891 Page 5 of 11 May 26, 2022
© 2022 Kleinfelder www.kleinfelder.com
vegetation communities and record any special-status or sensitive biological resources while in the field. Protocol-level surveys for special-status plant and wildlife species were not conducted during this time; however, any incidental observations of such species were documented.

Kleinfelder conducted a constraints-level analysis for potentially jurisdictional wetlands and waters based on current and historic aerial photography signatures and field observations. The analysis was based on criteria provided by the following agencies:
 Waters of the U.S., including wetlands, under the jurisdiction of the U.S. Army Corps of Engineers (ACOE), pursuant to Section 404 of the federal Clean Water Act (CWA).  Wetlands under the jurisdiction of the Regional Water Quality Control Board (RWQCB), pursuant to Section 401 of the CWA and the Porter-Cologne Water Quality Control Act (Porter-Cologne Act).
 Wetlands under the jurisdiction of CDFW, pursuant to Section 1602 of the California Fish and Game Code.

3 RESULTS

3.1 Biological Setting
The biological setting surrounding the study area is primarily developed with residences, industrial areas, and strip malls. The area south of the Camarillo Airport is primarily developed with agriculture.

3.2 Existing Conditions
A discussion of the results of the desktop review and the general characteristics observed within the study area during the field survey are presented below.

3.2.1 Soils
According to the NRCS (USDA 2022), two soil types have been mapped within the Project area, including Camarillo loam and Hueneme sandy loam (Figure 4).

Camarillo loam consists of poorly drained soils that formed in material weathered from alluvium derived from sedimentary rock. Camarillo loam occurs on uplands (alluvial fans and toeslopes).

Hueneme sandy loam is a poorly drained, very slightly saline to slightly saline soils that formed in material weathered from stratified alluvium derived from sedimentary rock. It is found on toeslopes and basin floors.

3.2.2 Vegetation Communities
Using the classifications described in A Manual of California Vegetation (Sawyer Keeler-Wolf 2009), one vegetation community, non-native annual grassland, was mapped within the Project area.

Non-Native Annual Grassland. This vegetation type is found throughout the Project area and is comprised of naturalized annual and perennial grassland (Figure 5). This vegetation community is generally dominated by non-native species, including introduced forbs. Native grasses and forbs may be present, but usually constitute less than 10 percent relative cover in the herbaceous layer. Species that were observed in this vegetation community during the field survey include wild oats (Avena sp.), Italian ryegrass (Festuca perennis), ricegrass (Piptatherum sp.), brome (Bromus sp.), mustard (Brassica sp.), wild radish (Raphanus raphanistrum), cheeseweed (Malva sp.), chrysanthemum (Chrysanthemum sp.), stinging nettle (Urtica dioica), epizote (Dysphania ambrosioides), Russian thistle (Salsola sp.), and castor bean (Ricinus communis). 20230187.001A/LH22R140891 Page 7 of 11 May 26, 2022
© 2022 Kleinfelder www.kleinfelder.com
Just outside of the eastern boundary of the parcel, there is a row of large ornamental landscape trees within the Home Depot lot.

3.2.3 Wetlands and Water Features
Although a formal wetland delineation was not performed during the field survey, no aquatic features were observed within the study area that are likely to fall under jurisdiction of the ACOE, CDFW, of RWQCB. Additionally, the NWI did not depict any aquatic resources within or adjacent to the study area.

3.3 Special-Status Wildlife Species with Potential To Occur in the Study Area Results of the CNDDB and IPaC searches indicated 14 special-status wildlife species known to occur within the one-quad/two-mile search radius of the Project area (CDFW 2022; USFWS 2022b). Of these, 13 species are not expected to occur or have a low potential to occur within the Project area due to a lack of suitable habitat, or the site is outside of the species’ known range; therefore, these 13 species were removed from further consideration. The remaining species, burrowing owl, has a moderate potential to occur at the site and is discussed further below.

Burrowing owl utilizes abandoned California ground squirrel (Otospermophilus beecheyi) burrows in open habitats, grasslands, and disturbed areas, typically on levees, mounds or areas where there are unobstructed views of possible predators such as raptors or foxes. Prey items include insects, small mammals, reptiles and amphibians. Although no California ground squirrel burrows were detected during the survey, there is suitable foraging habitat in the vicinity of the Project area, and there are five documented occurrences of this species within 1.3 miles of the Project area, one of which is located within the northwestern portion of the parcel (CDFW 2022).

No raptor nests, wildlife dens, or burrows were incidentally observed during the field survey. A list of wildlife species with potential to occur in the vicinity of the Project area is included in Appendix A. Recommendations to avoid and/or minimize impacts to burrowing owls that may occur in the Project area are provided in Section 4.

3.4 Special-Status Plant Species with Potential to Occur in the Study Area Results of the CNDDB and CNPS searches indicated 12 special-status plant species known to occur within the one-quad/two-mile search radius of the Project area (CNPS 2022). None of these species are expected to occur within or adjacent to the Project area due to a lack of suitable habitat, a lack of occurrences in the vicinity of the Project area, or the Project area is outside of 20230187.001A/LH22R140891 Page 8 of 11 May 26, 2022

the species’ known range; therefore, special-status plants are not discussed further in this document. A list of plant species with potential to occur in the vicinity of the Project area is included in Appendix B.

3.5 Critical Habitat
Critical habitat is a term defined and used in the federal Endangered Species Act to specify geographic areas that contain features essential to the conservation of an endangered or threatened species, and that may require special management and protection. Critical habitat may also include areas that are not currently occupied by the species but will be needed for its recovery.

The Project area does not fall within or adjacent to Critical Habitat limits for any listed plant or wildlife species.

3.6 Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the migration of animals. Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat fragmentation; they may be continuous habitat or discrete habitat islands that function as stepping stones for wildlife dispersal.

The study area is not recognized as an important wildlife corridor by any regional or state agency or jurisdiction and is not considered critical to the ecological functioning of adjoining open space areas. However, it likely supports local movement patterns of terrestrial wildlife species and provides food and cover resources for common and some special-status avian and reptile species. Temporary effects due to noise and increased human activity during project activities would not interfere with these local movement patterns over time or affect the ability of these species to forage or reproduce.

3.7 Common Wildlife Species
Five bird species were detected during the field survey, including red-winged blackbird (Agelaius phoeniceus), American crow (Corvus brachyrhynchos), cliff swallow (Petrochelidon pyrrhonota, which were observed nesting on the southern wall face of the existing Home Depot), mourning dove (Zenaida macroura), and northern mockingbird (Mimus polyglottos). Numerous red-winged blackbirds were observed feeding throughout the site on seeds of some of the weedy vegetation 20230187.001A/LH22R140891 Page 9 of 11 May 26, 2022

and were displaying potential nesting behavior; however, no nests were detected during the field survey. No common mammals, amphibians, or reptiles were detected during the field survey.

Common wildlife species adapted to life in proximity to human development, such as raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), and striped skunk (Mephitis mephitis) are likely to move through the study area on a regular basis to find food and cover. Several common native and non-native bird species are likely to use the study area for nesting and foraging (Figure 5).

4 RECOMMENDATIONS
This section addresses potential constraints to approval of the proposed Project as a result of the presence of sensitive biological resources and potential impacts to such resources that would result from Project activities. Recommendations to address potential biological resource constraints are described below.

BIO-1: Preconstruction Nesting Bird Survey. All native birds in California are protected by the federal Migratory Bird Treaty Act (MBTA) and provisions of Section 3503.5 of the California Fish and Game Code, which specifically protects raptors. Ground disturbance, noise, or removal of vegetation that would result in destruction of active bird nests or disruption of breeding/nesting activity could be a violation of the MBTA and the California Fish and Game Code, as well as a significant impact under CEQA.

Kleinfelder recommends a nesting bird survey be completed by a qualified biologist no earlier than one week prior to any construction during the nesting season (February 15–August 31) to determine if any native birds are nesting on or near the site (including a 250-foot buffer for burrowing owl and other raptors). If any active nests are observed during surveys, a suitable avoidance buffer from the nests should be determined by the qualified biologist based on species, location, and extent and type of planned construction activity. These nests would be avoided until the chicks have fledged and the nests are no longer active, as determined by the qualified biologist. Kleinfelder also recommends removing any suitable nesting habitat (i.e., trees and vegetation) outside of the bird breeding season to avoid impacts to nesting birds.

BIO-2: Trash Receptacles. Impacts to special-status species due to increased predation from construction activities could be considered a significant impact in the context of CEQA. All trash and waste items generated by construction or crew activities should be properly contained in a covered trash receptacle and removed from the Project area daily. This includes biodegradable items, such as apple cores and banana peels, that attract predators such as raccoons and American crows that could prey upon sensitive wildlife species. 20230187.001A/LH22R140891 Page 11 of 11 May 26, 2022

monarch –
California
overwintering
population
Danaus plexippus Candidate
Threatened/None
Monarch adults make massive, multi-generation migrations from August-October, flying south thousands of miles to hibernate along the California coast and in central Mexico. Monarchs stop to feed on flower nectar and to roost together at night. During warm winter days, the butterflies may take moisture and flower nectar. Most mating happens before they journey north in the spring, when females lay single eggs along the way under host plant leaves (Asclepias sp.); caterpillars eat flowers and leaves. Overwintering sites along the California coast are important for conservation of this species.

Not expected to occur. Suitable habitat
for this species is not present within or
adjacent to the Project area, and there
are no known winter roosts in the vicinity
of the Project area.

Riverside fairy
shrimp
Streptocephalus
woottoni
Endangered/None Riverside fairy shrimp have narrow habitat requirements and are restricted to deep lowland vernal pools that retain water for 2-8 months, and are generally 12 in or deeper. They will not hatch in shallow vernal pools or in vernal pools that receive cooler waters from early winter rains.

Not expected to occur. Suitable aquatic
habitat for this species is not present
within or adjacent to the Project area.
vernal pool fairy
shrimp
Branchinecta
lynchi
Threatened/None Vernal pool fairy shrimp is adapted to seasonally inundated aquatic features and occur primarily in vernal pools and seasonal wetlands that fill with water during fall and winter rains, then dry up in spring and summer. Typically, the majority of pools in any vernal pool complex are not inhabited by the species at any one time. Different pools within or between complexes may provide habitat for the fairy shrimp in alternative years, as climatic conditions vary.

Not expected to occur. Suitable aquatic
habitat for this species is not present
within the Project area.

Status¹ Habitat Associations Potential to Occur in the Project Area² Fish
arroyo chub Gila orcuttii None/SSC Arroyo chub are native to the streams and rivers of the Los Angeles plain in southern California, including the Los Angeles, San Gabriel, San Luis Rey, Santa Ana, and Santa Margarita Rivers, and Malibu and San Juan Creeks. They have been extirpated from much of their native range, but have been introduced to streams along the coast as far north as Chorro Creek in San Luis Obispo County. Arroyo chub are adapted to survive in cool to warm (10-24°C) streams that fluctuate between large winter storm flows, and low summer flows, and the low dissolved oxygen and wide temperature fluctuations associated with this flow regime. They are most common in slow flowing or backwater areas with sand or mud substrate, but may also inhabit areas with velocities in excess of 80 cm/s over coarse substrate. They feed on plants such as algae and water fern (Azolla sp.), and on invertebrates such as insects and mollusks.

Not expected to occur. Suitable aquatic
habitat for this species is not present
within or adjacent to the Project area.

Amphibians and Reptiles
southern California
legless lizard
Anniella stebbinsi None/SSC Often locally abundant, this species is found in coastal sand dunes and a variety of interior habitats, including sandy washes and alluvial fans. Much of the preferred coastal dune habitat has been destroyed by coastal development between Ventura County and the Mexican Border.

Not expected to occur. Suitable aquatic
habitat for this species is not present
within or adjacent to the Project area.
two-striped
gartersnake
Thamnophis
hammondii
None/SSC Two-striped gartersnake is generally found near water sources such as pools, creeks, cattle tanks, and other aquatic features, often in rocky areas. Associated vegetation includes oak woodland, willow, coastal sage scrub, scrub oak, sparse pine, chaparral, and brushland.

Not expected to occur. Suitable
habitat for this species is not present
within or adjacent to the Project area.
western pond turtle Emys marmorata None/SSC Western pond turtles are found in rivers, lakes, streams, ponds, wetlands, ephemeral creeks, reservoirs, agricultural ditches, estuaries, and brackish waters. Western pond turtles prefer areas that provide cover from predators, such as vegetation and algae, as well as basking sites for thermoregulation. Adults tend to favor deeper, slow-moving water, whereas hatchlings search for slow and shallow water that is slightly warmer. Terrestrial habitats are used for egg laying and wintering and usually consist of burrows in leaves and soil. They are rarely found at altitudes above 1,500 meters.

Low potential to occur. Although
suitable aquatic habitat for this species is
present within Revelon Slough
approximately 700 feet south of the
Project area, and there is a documented
occurrence from 2013 in the slough, this
species is unlikely to cross West Ventura
Boulevard to access potential nesting
habitat on the site.

burrowing owl Athene
cunicularia
None/SSC Burrowing owl utilizes abandoned ground squirrel burrows in open habitats, grasslands, and disturbed areas, typically on levees, mounds or areas where there are unobstructed views of possible predators such as raptors or foxes. Prey items include insects, small mammals, reptiles and amphibians.

Moderate potential to occur. There is
suitable habitat for this species within the
Project area and five documented
occurrences of this species within 1.3
miles of the Project area, one of which is
located on the northwest portion of the
Project parcel (the adjacent lot).
coastal California
gnatcatcher
Polioptila
californica
californica
Threatened/SSC California Gnatcatchers live in coastal sage scrub, desert scrub, and coastal dune scrub year-round. In California they occur along the coast in areas dominated by California sagebrush. They generally occur in areas less than 1,600 feet in elevation, but sometimes occur at higher elevation at inland scrub sites.

Not expected to occur. Suitable habitat
for this species is not present within or
adjacent to the Project area.
least Bell’s vireo Vireo bellii
pusillus
Endangered/Endangered Least Bell's vireo primarily occupies riverine riparian habitats, including dry portions of intermittent streams that typically provide dense cover within 3-6 feet of the ground, often adjacent to a complex, stratified canopy. Least Bell’s vireo prey items include bugs, beetles, grasshoppers, moths, spiders, and caterpillars. They glean insects from leaves, twigs, and branches by hovering and picking prey off these stationary objects, and also utilize aerial pursuit.

Not expected to occur. Suitable habitat
for this species is not present within or
adjacent to the Project area.
marbled murrelet Brachyramphus
marmoratus
Threatened/Endangered Marbled murrelet generally occurs on calm protected waters near the coast, including bays, inlets, and among islands. Most foraging occurs in fairly shallow water. Marbled murrelet breeds inland on mountains near the coast, and nests on mountainsides well inland in mature forest habitat. It is sometimes found on lakes near the coast.

Not expected to occur. Suitable habitat
for this species is not present within or
adjacent to the Project area.
southwestern
willow flycatcher
Empidonax traillii
extimus
Endangered/Endangered Willow flycatcher is found in bushes, willow thickets, brushy fields, and upland groves. It breeds in thickets of deciduous trees and shrubs, especially willows, or along woodland edges. It is often found near streams or marshes (especially in southern part of range).

Not expected to occur. Suitable habitat
for this species is not present within or
adjacent to the Project area.
white-tailed kite Elanus leucurus None/FP White-tailed kite nests in woodlands, riparian habitat, and individual trees near open land. It forages opportunistically in grassland, meadows, scrub, agriculture, emergent wetland, savanna, and disturbed habitat.

Low potential to occur. Although
suitable habitat for this species is
present within and adjacent to the
Project area, the nearest documented
occurrence is five miles southeast of the
site and is from 2009.

Status¹ Habitat Associations Potential to Occur in the Project Area² Mammals
American badger Taxidea taxus None/SSC American badger is most abundant in drier open stages of most shrub, forest and grassland habitats with friable soils. It digs burrows for cover and will reuse burrows occasionally but may also dig new burrows each night in the summer. Its diet consists of rodents, small mammals, reptiles, insects, birds and carrion.

Low potential to occur. Although
potentially suitable habitat exists for this
species on the site, there are no
documented occurrences of this species
within three miles of the Project area,
and development surrounding the site
likely precludes this species from
occurring. 1Status Legend
SSC: Species of Special Concern (CDFW)

2 Definitions Regarding Potential for Occurrence
• Not expected to occur – Habitat within and adjacent to the Project site is unsuitable for the species life history requirements (foraging, breeding, cover, range, elevation, hydrology, vegetation community, site history, and/or disturbance regime) There are no documented occurrences of the species in the vicinity of the Project site. • Low – Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the Project site is unsuitable or of poor quality. The species is not likely to found within the Project site. Any documented occurrences are farther than likely possible for the species to occur in the Project site. • Moderate – Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the Project site is unsuitable. There are documented occurrences in the near vicinity of the Project site and therefore, the species has a moderate probability of being found within the Project site. • High – All of the habitat components meeting the species requirements are present, and/or most of the habitat on or adjacent to the Project site is highly suitable. There are documented occurrences of the species on or immediately adjacent to the Project site and therefore, the species has a high probability of being found within the Project site. • Present – Species was observed within the Project site or has been recorded (i.e., CNDDB, or other reports) within the Project site recently.
