1.3.3 REGIONAL AND LOCAL PLANS
Coachella Valley Multiple Species Habitat Conservation Plan The County of Riverside developed the CVMSHCP (Coachella Valley Association of Governments [CVAG] 2007) to enhance and maintain biological diversity and ecosystem processes while allowing future economic growth. The CVMSHCP sets Conservation Goals and Objectives to ensure conservation of the Covered Species and conserved natural communities in the CVMSHCP Reserve System. In addition to setting Conservation Goals and Objectives for the Covered Species and conserved natural communities, the CVMSHCP has designated Core Habitat, Other Conserved Habitat, Essential Ecological Processes, and Biological Corridors and Linkages. The CVMSHCP area is divided into Conservation Areas based on a combination of ecological and jurisdictional factors.
2 METHODS

2.1 Biological Resources Assessment
Prior to commencing field surveys, RBC conducted a literature and database review to assist in determining the existence or potential occurrence of special-status biological resources on and within the vicinity of the project site. RBC queried the CVMSHCP database (Figure 2; CVAG 2019), California Natural Diversity Database (CNDDB; Figure 3; CDFW 2019), USFWS database for special-status species, and USFWS database for endangered species and critical habitat (USFWS 2019a) within a five-mile radius of the project site. RBC also queried the California Native Plant Society Inventory of Rare and Endangered Plants of California (CNPS Inventory; CNPS 2019) within the nine USGS quadrangles surrounding the project site. These databases contain records of reported occurrences of state- and federally listed species or otherwise sensitive species and habitats that may occur within or within vicinity of the project site. RBC also reviewed other available technical information on the biological resources of the area, including previous surveys and recent findings on adjacent project sites.

In April and May 2019, RBC biologists conducted vegetation mapping, habitat assessments, and a general biological survey within the project site. Survey dates, times, and environmental conditions during the field surveys are presented in Table 1.

BB = Brenda Bennett, LR = Lee Ripma, TS = Taku Shiozaki During the field surveys biologists took notes on existing site conditions, vegetation, and suitability of habitat for special-status species with potential to occur on site. Wildlife species were documented during field surveys by sight, calls, tracks, or scat. Plant species were recorded and mapped in the field and, if necessary, species identification was confirmed in the lab. In addition to species observed, expected wildlife usage of the project site was determined by known habitat preferences of regional wildlife species and knowledge of their relative distributions in the area.

2.2 Aquatic Resources Delineation
RBC conducted a formal aquatic resources delineation between May 7 and May 10, 2019 in order to identify areas that may be considered jurisdictional under the Corps pursuant to Section 404 of the CWA; jurisdictional under the RWQCB pursuant to Section 401 of the CWA and the PorterCologne Act, and streambed and riparian habitats under the CDFW pursuant to Cal. Fish and Game Code (§1602). Complete methods and results are presented in the Desert Lakes Project Jurisdictional Delineation Report (RBC 2019).
3 RESULTS

3.1 Existing Site Conditions
The project site is located within the Coachella Valley within the Sonoran Desert region, a subdivision of the Colorado Desert. The site is mostly undeveloped land, consisting of gentlysloped terrain within the broad alluvial fan derived from the Little San Bernardino Mountains to the north, with the bedrock highlands of the Little San Bernardino and Orocopia Mountains to the northeast, east, and southeast. The project site includes several southwest-trending ridges of relatively low relief with alluvial drainages that drain into a larger alluvial fan. The western extent of the project site (adjacent to the Coachella Canal) has been subject to historic human disturbance, including previous agricultural use. On-site disturbances include unpaved roads, power lines, illegal dumping, and Off Highway Vehicle (OHV) use.

The project site lies within the boundary of the CVMSHCP planning area and a small portion of the EIHCA is present at the far western boundary of the site. The site is also in the immediate vicinity of the Desert Tortoise Linkage and Conservation Area (Figure 2).

3.2 Topography and Soils
Elevations on the project site range from approximately 35 to 758 feet above mean sea level (amsl).

Surface drainage generally runs from the northeast to the southwest. Per soils data from the National Resource Conservation Service (NRCS), the soils onsite consist of the following types:

Badland; Borrow pits; Carrizo stony sand (2 to 9 percent slopes); Carsitas gravelly sand (0 to 9 percent slopes); Carsitas cobbly sand (2 to 9 percent slopes); Chuckwalla very gravelly sand clay loam (2 to 5 percent slopes); and Myoma fine sand (0 to 5 percent slopes). Soil types within the project site are presented on Figure 4.

3.3 Vegetation communities and Land Uses
There are six vegetation communities and/or land uses within the project site. The site is primarily comprised of Sonoran creosote bush scrub. The numerous ephemeral washes on site generally contain a mix of desert wash scrub and Sonoran creosote bush scrub. A list of vegetation communities and land uses and their size within the project site is provided in Table 2. A list of plants observed during the field surveys is provided in Appendix B. A map of the vegetation and land uses is presented on Figure 5.

TOTAL 2812.08
Sonoran Creosote Bush Scrub
Sonoran creosote bush scrub (1855.20 acres) is the dominant habitat type within the project site.

This community occurs on upland slopes, hills, bajadas, and alluvial fans, and within the ephemeral washes on site. Sonoran creosote bush scrub is dominated by widely-spaced stands of creosote bush (Larrea tridentata) with open soil, annual plants, and other shrubs occurring between creosote bush shrubs. Other common shrubs within this community include white bursage (Ambrosia dumosa), brittlebush (Encelia farinosa), and desert-holly (Atriplex hymenelytra).

Observations of short-lived annual plant species was limited due to the timing of the field survey.

Desert Wash Scrub/Sonoran Creosote Bush Scrub
An intermixing of two vegetation types; desert wash scrub and Sonoran creosote bush scrub occur across large areas of the project site (916.00 acres) most often within, but not limited to, the numerous ephemeral washes on site. These washes contain a mix of species associated with both vegetation types including desert-lavender (Condea emoryi), smoke tree (Psorothamnus spinosus),

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

ROCKS BIOLOGICAL CONSULTING 8
indigo bush (Psorothamnus schottii), desert bird-of-paradise (Hoffmannseggia microphylla), rush sweet-bush (Bebbia juncea var. aspera), catclaw acacia (Senegalia greggii), and occasional blue palo verde (Parkinsonia florida), as well as creosote bush and white bursage.

Mesquite Hummocks
Mesquite hummocks (0.99 acre) occur only on the western portion of the project site within the EIHCA. Mesquite hummocks consist solely of mesquite (Prosopis glandulosa var. glandulosa) on a raised hummock of blown sand. These habitats are important habitat for wildlife and have a stabilizing effect on sand dunes.

Agricultural Land
Agricultural land within the project site (2.43 acres) consists of grapevines under active cultivation.

Agricultural areas are both disturbed and irrigated and provide little habitat for native plant and wildlife species.

Disturbed Habitat
Disturbed habitat within the project site (36.48 acres) consists primarily of bare soils and non-native species resulting from human disturbance. Disturbed lands have been graded, cleared, or used to the point where the land cannot support native vegetation. Disturbed areas occur mostly in the western portion of the site adjacent to agricultural land.

Tamarisk Scrub
Tamarisk scrub (0.99 acre) within the project site consists primarily of dense tamarisk (Tamarix ramosissima) shrubs. Tamarisk scrub typically occurs on sandy or gravelly soils within, or in close proximity to washes or streams and often follows major anthropogenic disturbance. Tamarisk scrub occurs in the western portion of the site in areas disturbed by both agriculture and construction of a water tower.

3.4 Wildlife
Avian species observed in the project site include mourning dove (Zenaida macroura), red-tailed hawk (Buteo jamaicensis), common raven (Corvus corax), house finch (Haemorphus mexicanus), loggerhead shrike (Lanius ludovicianus), northern mockingbird (Mimus polyglottos), verdin (Auriparus flaviceps), black-tailed gnatcatcher (Polioptila melanura), black-throated sparrow (Amphispiza bilineata), Wilson’s warbler (Cardellina pusilla), barn swallow (Hirundo rustica), and turkey vulture (Cathartes aura).

Reptile species observed within the project site include desert iguana (Dipsosaurus dorsalis) and common-side blotched lizard (Uta stansburiana). No amphibian species were observed or heard within the project site and none are expected to occur.

Mammal species observed in the project site include black-tailed jackrabbit (Lepus californicus), coyote (Canis latrans), white-tailed antelope squirrel (Ammospermophilus leucurus), and desert cottontail (Sylvilagus audubonii). A complete list of animal species observed, heard, or inferred from sign or scat is provided in Appendix C.

ROCKS BIOLOGICAL CONSULTING 9
Butterfly species observed in the project site include striated queen (Danaus gilippus strigosus) and western pygmy blue (Brephidium exilis exilis).

3.5 Special-Status Biological Resources
Special-status biological resources are those defined as follows: 1) Species that have been given special recognition by federal, state, or local conservation agencies and organizations due to limited, declining, or threatened/endangered population sizes; 2) Species and habitat types recognized by local and regional resource agencies as sensitive; 3) Habitat areas or vegetation communities that are unique, are of relatively limited distribution, or are of particular value to wildlife; 4) Wildlife corridors and habitat linkages; and/or 5) Biological resources that may or may not be considered sensitive, but are regulated under local, state, and/or federal laws.

For purposes of this report, species are considered to have special status if they meet one or more of the following criteria:
• Listed under the federal or state Endangered Species Act • USFWS Birds of Conservation Concern
• CDFW Species of Special Concern
• CDFW Fully Protected Species
• Covered as a state protected furbearing mammal (14 California Code of Regulations [14 CCR Section 460])
• Listed as having a California Rare Plant Rank (CRPR; exc. CRPR 4) • Record reported in the CNDDB and/or USFWS database
The literature review revealed 43 special-status species (13 plants, 30 animals) with the potential to occur within or immediately adjacent to the project site. The following addresses threatened/endangered species and other non-listed special-status species identified as potentially present on the project site. A list of these species and a discussion of their potential to occur within the project site is included in Appendix D.

No state- and/or federally listed threatened or endangered species were observed onsite during the general biological field survey. However, the search of the CNDDB and USFWS databases shows three listed species have been documented within a five-mile radius of the project site as follows:
• Desert tortoise (Gopherus agassizii); federally listed threatened and state-listed threatened; CVMSHCP covered species
• Coachella Valley fringe-toed lizard (Uma inornata); federally listed threatened and statelisted endangered; CVMSHCP covered species • Coachella Valley milk-vetch (Astragalus lentiginosus var. coachellae); federally listed endangered; CVMSHCP covered species
Habitat on the project site is moderately suitable for Coachella Valley milk vetch and desert tortoise. No suitable habitat for the Coachella Valley fringe-toed lizard is present on the project site.

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 10
Additionally, the project site is not within any USFWS-designated Critical Habitat for the Coachella Valley milk-vetch, desert tortoise, or Coachella Valley fringe-toed lizard.

Two non-listed special-status species; loggerhead shrike and black-tailed gnatcatcher were observed during the general biological surveys (Figure 5). Based on review of the CNDDB, USFWS database, and CNPS Inventory, 39 non-listed special-status species (12 plants and 27 animals) have been documented within a five-mile radius of the project site or have the potential to occur on the project site.

An analysis of the likelihood for occurrence of each special-status species documented within a 5- mile radius of the project site or potential to occur is provided in Appendix D. This analysis considers species range as well as documentation within the vicinity of the project area and includes the habitat requirements for each species and the potential for their occurrence on the site, based on required habitat elements and range relative to the current site conditions.

3.6 Burrowing Owl and Nesting Birds
Highly suitable habitat for burrowing owl (Athene cunicularia) and other special-status species such as Le Conte’s thrasher (Toxostoma lecontei), loggerhead shrike (observed), and black-tailed gnatcatcher (observed), as well as numerous more common bird species is present within the project site and adjacent areas. These birds (common and special-status) are protected by Cal.

Fish and Game Code, which make it unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed under 50 CFR 10.13, including feathers or other parts, nests, eggs, or products, except as allowed by implementing regulations (50 CFR 21). The MBTA prohibits ‘take’ of nearly all native birds.

3.7 Jurisdictional Waters and Streambeds
The aquatic resources delineation determined that the project site supports Corps-jurisdictional non-wetland waters of the U.S., RWQCB-jurisdictional non-wetland waters of the State, and CDFW-jurisdictional non-wetland streambed, associated riparian habitat, and/or watercourse (RBC 2019). The total acreage and linear feet of each resource type is summarized in Table 3 below.

Table 3. Jurisdictional Resources within Project Site
Agency Resource Type Total Acreage Total Linear Feet
Corps Non-wetland waters of the U.S. 2.72 2,957
RWQCB Non-wetland waters of the U.S./State 637.37 282,372 CDFW
Streambed (Bank) 637.37 282,372
Riparian Vegetation 0.20 n/a
Estimated jurisdictional features observed within the project survey area during the formal jurisdictional delineation field effort include Feature (F) 1 to F16 and the Coachella Canal (Figure 6).

Each named/numbered feature represents a separate watercourse, and as such, includes all functionally related and connected single-thread channels, compound channels, braided channels,

Item 25.

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 11
and floodplains. Features that may connect outside of the project survey boundary were not deemed to be functionally related or connected for purposes of naming each on-site feature.

The Coachella Canal would be considered a Corps-jurisdictional non-wetland waters of the U.S. as a tributary (i.e., 33 CFR 328.3(a)(5)) to the Whitewater River and ultimately the Salton Sea. The Coachella Canal and F1 to F16 (excluding F1 – Tamarisk Scrub and F13 – Tamarisk Scrub) would be considered non-wetland waters of the State/surface waters per the RWQCB. RBC also expects the Coachella Canal and F1 to F16 would be considered CDFW streambed, associated riparian habitat, and/or watercourse as defined by the Mapping Episodic Stream Activity (MESA) Field Guide (Vyverberg et. al. 2013). Generally, areas deemed as jurisdictional by the RWQCB and CDFW consist of watercourses comprised of ephemeral desert wash.

3.8 CVMSHCP Conservation Areas
As shown in Figure 2, the western portion of the project site is within the EIHCA and the project site shares a common boundary along the north and northeastern frontage with the Desert Tortoise and Linkage Conservation Area. Approximately 61 acres of the project site are within the EIHCA. This area within the EIHCA consists of Sonoran creosote bush scrub, mesquite hummocks, tamarisk scrub, disturbed habitat, and agricultural land. This portion of the project site is mapped as Other Conserved Habitat for LeConte’s thrasher, Coachella Valley round-tailed ground squirrel (Spermophilus tereticaudus chlorus), and flat-tailed horned lizard (Phrynosoma mcallii), which are all Covered Species under the CVMSHCP. The EIHCA is part of the watershed for mesquite hummocks and provides potential habitat connectivity with the Thousand Palms Conservation Area through the Indio Hills Palms Conservation Area to the west.

3.9 CVMSHCP Modeled Habitat
The project site supports modeled habitat (CVAG 2019) for the following special-status species:
• desert tortoise; federally and state endangered, CVMSHCP Covered Species • Coachella Valley [Palm Springs] round-tailed ground squirrel; CDFW SSC, CVMSHCP Covered Species
• crissal thrasher; CDFW SSC, CVMSHCP Covered Species
• flat-tailed horned lizard; CDFW SSC, CVMSHCP Covered Species • least Bell’s vireo; federally and state endangered, CVMSHCP Covered Species • LeConte’s thrasher; USFWS BCC, CDFW SSC, CVMSHCP Covered Species • Palm Springs pocket mouse; CDFW SSC, CVMSHCP Covered Species • summer tanager; CDFW SSC, CVMSHCP Covered Species
• yellow warbler; USFWS BCC, CDFW SSC, CVMSHCP Covered Species • yellow-breasted chat; CDFW SSC, CVMSHCP Covered Species

4 IMPACTS

4.1 Threatened and Endangered Species
No state- or federally threatened or endangered species were observed during the general biological field survey. There is moderate potential for the federally and state-threatened desert tortoise to occur within the project site and low potential for the federally endangered Coachella Valley milk-vetch and the federally endangered and state-threatened Coachella Valley fringe-toed lizard to occur. In addition, suitable migration habitat for the federally and state-endangered least Bell’s vireo is present onsite, but no breeding habitat is present, and this species is unlikely to nest within the project site. All four of these species are covered by the CVMSHCP. Any potential impacts on these species will be covered through compliance with the CVMSHCP.

Please note that while impacts on desert tortoise and their habitat are covered through participation in the CVMSHCP (and pre-established mitigation measures), the USFWS Permit Conditions for the CVMSHCP require that the USFWS be notified 45 days prior to the issuance of a grading permit to allow for the potential salvage of adult tortoises within the notification time period or that desert tortoise clearance surveys be conducted per USFWS protocol.

4.2 Non-Listed Special Status Species
Two non-listed special-status species; loggerhead shrike and black-tailed gnatcatcher were observed during the general biological field survey. RBC identified 39 non-listed special-status species that have a low, moderate, or high potential to occur within the project site (Appendix D).

These species have no official state or federal protection status; however, they are required to be considered under CEQA. Of the non-listed special status species with potential to occur on the project site 13 are covered by the CVMSHCP while 26 species are not covered.

Through implementation of the CVMSHCP Reserve System and conservation objectives, the covered species are considered protected and adequately conserved through the CVMSHCP’s pre-established Conservation Areas and avoidance, minimization, and mitigation measures. The non-listed special status species that are not covered by the CVMSHCP occur within the same habitats as the covered species and still considered relatively common within the Reserve System and across the Coachella Valley. Therefore, the project would not have significant impacts on any of the non-listed special species that could potentially occur onsite.

4.3 Special-status Plant Communities/California Desert Native Plants Act
There will be no impacts on special-status plant communities as no such habitats occur on the project site.

4.4 Burrowing Owl and Migratory Birds
The burrowing owl, a species protected under the MBTA and the Cal. Fish and Game Code and covered under the CVMSHCP has high potential to occur on the project site. Impacts on burrowing owl would be considered less than significant through participation in the CVMSHCP;

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 13
however, under the MBTA, project-related impacts on burrowing owl will require mitigation to ensure compliance with the MBTA and Cal. Fish and Game Code. Activities that cause destruction of active nests, or that cause nest abandonment and subsequent death of eggs or young may constitute violations of one or both of these laws. In order to comply with these state and federal regulations, a pre-construction survey for the burrowing owl is required on the project site 30 days prior to site disturbance. If burrowing owl is found to be present, avoidance measures will be required following accepted protocols. If burrowing owl is found to be present during the breeding season (February 1 to August 31), no ground disturbance can begin within the occupied area until after the breeding season (i.e., after August 31) and/or until the burrowing owl have completed their nesting activities. Any relocation efforts must be coordinated with CDFW and/or USFWS.

Additionally, the project has the potential to impact active bird nests if vegetation is removed or ground disturbing activities are initiated during the nesting season (February 1 to August 31). The existing habitat on site supports special-status species loggerhead shrike and black-tailed gnatcatcher and has potential to support nesting bird species such as Le Conte’s thrasher and several raptor species. Impacts on nesting birds are prohibited by the MBTA and Cal. Fish and Game Code, as such, ground-disturbing activities, including vegetation clearing, should be conducted outside of the nesting season. If avoidance of the nesting season is not feasible then a qualified biologist should conduct a nesting bird survey within three days prior to any disturbance of the project site, including disking, excavation, and grading. If active nests are identified, the qualified biologist shall establish suitable buffers around the nests depending on the level of activity within the buffer and sensitivity of the species observed. The buffer areas shall be avoided until the nests are no longer occupied and juvenile birds can survive independently from the nest.

4.5 Jurisdictional Waters and Streambeds
RBC expects that the Corps, RWQCB, and CDFW would take jurisdiction over aquatic resources on the project site as follows:
• Corps Jurisdiction - one non-wetland waters of the U.S., the Coachella Canal, totaling 2.72 acres (2,957 linear feet)
• RWQCB Jurisdiction - the Coachella Canal and non-wetland waters of the State/surface waters F1 to F16 (excluding F1 – Tamarisk Scrub and F13 – Tamarisk Scrub), totaling 637.37 acres (282,372 linear feet)
• CDFW Jurisdiction - the Coachella Canal and non-wetland streambed, associated riparian habitat, and/or watercourse F1 to F16, totaling 637.57 acres (282,372 linear feet) Assuming the Corps finalizes the Approved Jurisdictional Determination (AJD) and concludes that F1 to F16 are not jurisdictional, no Corps permitting would be required for the project assuming the proposed project will not impact the Coachella Canal. Impacts on jurisdictional features per other agencies (if deemed jurisdictional) would require Waste Discharge Requirements (WDR) from RWQCB and a Streambed Alteration Agreement (SAA) from CDFW. The RWQCB and/or CDFW may also require a functional assessment (e.g., California Rapid Assessment Method [CRAM]) to quantitatively estimate the stream condition for the evaluation of the proposed project. Additionally,

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 14
compensatory mitigation would be required by the regulatory agencies to offset the proposed project impacts.

4.6 Wildlife Corridors
The western-most area of the project site lies within the EIHCA which serves as a biological corridor and linkage to the Indio Hills Conservation Area through the Thousand Palms Conservation Area, which ultimately links with Joshua Tree National Park. The adjacent Desert Tortoise Linkage and Conservation Area provides biological corridors and linkages to the Little San Bernardino Mountains and their associated canyon mouths and alluvial fans, which provide a linkage to the central part of the Plan Area.

A wildlife corridor can be defined as a physical feature that links wildlife habitat, often consisting of native vegetation that joins two or more larger areas of similar wildlife habitat. Corridors enable migration, colonization, and genetic diversity through interbreeding and are therefore critical for the movement of animals and the continuation of viable populations. Through avoidance of impacts on the portion of the EIHCA that occurs on site and compliance with the CVMSHCP the project will not have a significant impact on regional wildlife movement.

4.7 Local Policies and Ordinances
The project would not conflict with local policies or ordinances because the project will adhere to CVMSHCP guidelines and procedures. The project will be required to adhere to CVMSHCP Section 4.5 Lan Use Adjacency Guidelines (Guidelines; CVAG 2007), which state:

The purpose of [Guidelines] is to avoid or minimize indirect effects from [d]evelopment adjacent to or within the Conservation Areas. Adjacent means sharing a common boundary with any parcel in a Conservation Area. Such indirect effects are commonly referred to as edge effects, and may include noise, lighting, drainage, intrusion of people, and the introduction of non-native plants and non-native predators, such as dogs and cats. Edge effects will also be addressed through reserve management activities such as fencing.

These Guidelines include:

Drainage – Proposed [d]evelopment adjacent to or within a Conservation Area shall incorporate plans to ensure that the quantity and quality of runoff discharged to the adjacent Conservation Area is not altered in an adverse way when compared to existing conditions. Stormwater systems shall be designed to prevent the release of toxins, chemicals, petroleum products, exotic plant materials or other elements that might degrade or harm biological resources or ecosystem processes within the adjacent Conservation Area.

Toxics – Land uses proposed adjacent to or within a Conservation Area that use chemicals or generate bio-products such as manure that are potentially toxic or may adversely affect wildlife and plant species, Habitat, or water quality shall incorporate measures to ensure that application of such chemicals does not result in any discharge to the adjacent Conservation Area.

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 15
Lighting – For proposed [d]evelopment adjacent to or within a Conservation Area, lighting shall be shielded and directed toward the developed area. Landscape shielding or other appropriate methods shall be incorporated in project designs to minimize effects of lighting adjacent to or within the adjacent Conservation Area in accordance with the guidelines to be included in the Implementation Manual.

Noise – Proposed [d]evelopment adjacent to or within a Conservation Area that generates noise in excess of 75 dBA Leq hourly shall incorporate setbacks, berms, or walls, as appropriate, to minimize the effects of noise on the adjacent Conservation Area in accordance with the guidelines included in the Implementation Manual.

Invasives – Invasive, non-native plant species shall not be incorporated in the landscape for land uses adjacent to or within a Conservation Area. Landscape treatments within or adjacent to a Conservation Area shall incorporate native plant materials listed in Table 4- 112 of the CVMSHCP to the maximum extent [f]easible. The plants listed in Table 4-113 of the CVMSHCP are considered invasive and shall not be used within or adjacent to a Conservation Area. This list may be amended from time to time through a Minor Amendment with Wildlife Agency Concurrence.

Barriers – Land uses adjacent to or within a Conservation Area shall incorporate barriers in individual project designs to minimize unauthorized public access, domestic animal predation, illegal trespass, or dumping in a Conservation Area. Such barriers may include native landscaping, rocks/boulders, fencing, walls and/or signage.

Grading/Land Development – Manufactured slopes associated with site [d]evelopment shall not extend into adjacent land in a Conservation Area.

4.8 Cumulative Impacts
Cumulative impacts refer to incremental individual environmental effects of two or more projects when considered together. Such impacts taken individually may be minor but are collectively significant in light of regional impacts. The CVMSHCP has analyzed cumulative effects within the region of the project under CEQA, NEPA, CESA, and ESA. Because the project will comply with the CVMSHCP any cumulative project impacts would be less than significant. 5 REQUIRED AVOIDANCE, MINIMIZATION, AND MITIGATION

MEASURES
The following discussion provides project-specific avoidance, minimization, and mitigation measures that may be required by the lead agency for impacts on special-status resources.

5.1 Desert Tortoise
Moderately suitable habitat for the desert tortoise is present on the project site and modeled habitat per the CVMSHCP GIS data is present across the entire project site. While impacts on desert tortoise and their habitat will be covered through participation in the CVMSHCP, the USFWS Permit Conditions for the CVMSHCP require that the USFWS be notified 45 days prior to the

Item 25.

KPC COACHELLA BIOLOGICAL RESOURCES ASSESSMENT AND

CVMSHCP CONSISTENCY REPORT
ROCKS BIOLOGICAL CONSULTING 16
issuance of a grading permit to allow for the potential salvage of adult tortoises within this notification time period or that desert tortoise clearance surveys are conducted per USFWS protocol.

5.2 Burrowing Owl
Suitable habitat for the CDFW SSC burrowing owl is present on site and the potential for this species to occur is high. The direct take of a burrowing owl, or any raptor, must be avoided. In accordance with CDFW’s Staff Report on Burrowing Owl Mitigation (CDFG 2012) two preconstruction take avoidance surveys should be conducted prior to any vegetation removal, ground disturbance, or similar activity as follows:

No less than thirty days prior to the onset of ground disturbance, a qualified biologist shall survey the construction limits of the Project and 500-foot buffer for the presence of burrowing owls and occupied nest burrows, in accordance with the Staff Report on Burrowing Owl Mitigation (CDFG 2012). A final survey shall be conducted within 24 hours prior to ground disturbance.

If nesting and/or activity is present at any burrow site, then the active burrow shall be protected until nesting activity has ended to ensure compliance with Section 3503.5 of the California Fish and Game Code. Nesting activity for burrowing owls normally occurs from February 1 to August 31. To protect any burrow site, the following restrictions on construction are required between February 1 to August 31:
1) Clearing limits will be established a minimum of 300 feet in any direction from any occupied burrow; and
2) Access and surveying will not be allowed within 50 feet of any occupied burrow. Any occupied burrows found during the survey efforts shall be mapped on the construction plans and an ESA avoidance buffer shall be established. Construction during the non-nesting season can occur only at the sites if a qualified biologist has determined that the burrows are no longer active. If an active burrow is observed during the non-nesting period, the burrow site will be monitored by a qualified biologist, and when the owl is outside the burrow entrance, the biologist will flush any owl to open space areas. The biologist will then excavate the burrow site with tools or fill the burrow with soil so owls cannot return to the burrow site.

Note that any relocation efforts must be coordinated with the CDFW and/or USFWS. If a burrowing owl is found to be present during the breeding season (February 1 to August 31), no ground disturbance can begin within the occupied area until after the breeding season (i.e., after August 31) and/or until the burrowing owl have completed their nesting activities. Generally, a 300- to 500- foot buffer is required around nesting owls during construction activities.

5.3 Nesting Birds
To avoid direct impacts to raptors and/or native/migratory birds, removal of habitat that supports active nests in the proposed area of disturbance should occur outside of the breeding season for these species (February 1 to September 15). If removal of habitat in the proposed area of disturbance must occur during the breeding season, a qualified avian biologist shall conduct a preconstruction survey to determine the presence or absence of nesting birds in the proposed area of disturbance. The pre-construction survey shall be conducted three calendar days prior to the start of construction activities (including removal of vegetation). If nesting birds are observed, a letter report or mitigation plan in conformance with applicable state and federal law (i.e. appropriate follow-up surveys, monitoring schedules, construction and noise barriers/buffers, etc.) shall be prepared and include proposed measures to be implemented to ensure that take of birds or eggs or disturbance of breeding activities is avoided. The report or mitigation plan shall be submitted to CDFW and/or USFWS, as applicable, for review and approval and implemented to the satisfaction of the agency(ies). The project biologist shall verify and approve that all measures identified in the report or mitigation plan are in place prior to and/or during construction. If nesting birds are not observed during the pre-construction survey, no further mitigation is required.

5.4 Jurisdictional Waters and Streambeds
If there are no impacts on the Coachella Canal, no Corps permit would be required. Impacts on jurisdictional features per RWQCB and CDFW (if deemed jurisdictional) would require WDR from RWQCB and SAA from CDFW. The RWQCB and/or CDFW may also require a functional assessment (e.g., CRAM) to quantitatively estimate the stream condition for the evaluation of the proposed project. Additionally, compensatory mitigation would be required by the regulatory agencies to offset the proposed project impacts. We recommend consulting with the regulatory agencies as soon as possible in the project planning process to avoid/reduce processing delays.

5.5 East Indio Hills Conservation Area
The project is within the EIHCA and adjacent to the Desert Tortoise Linkage and Conservation Area. In order to avoid direct impacts on the EIHCA, it is recommended the project dedicate the entire portion of the project site within the EIHCA as conserved open space. Dedication of this portion of the project site would ensure that the project would not conflict with the CVMSHCP Conservation Objectives. The project would comply with CVMSHCP Section 4.5 Land Use Adjacency Guidelines to avoid and minimize indirect effects to the adjacent Desert Tortoise Linkage and Conservation Area.

5.6 Development Mitigation Fee
Per the CVMSHCP Section 5.2.1.1 Local Development Mitigation Fee, the project will be conditioned by the lead agency to pay a mitigation fee for the costs of mitigating impacts of the project. See Table 4 below for the Local Development Mitigation Fee per building type.

6 CONCLUSIONS
In summary, the 2,812-acre project site supports sensitive biological resources including jurisdictional waters of the state and U.S., two non-listed special-status bird species, moderate potential to support the state and federally-threatened desert tortoise, low potential to support the federally endangered Coachella Valley milk-vetch, and moderate to high potential to support numerous non-listed special-status species including burrowing owl. In addition, 61 acres of the project site is within the EIHCA.

The CVMSHCP was developed to enhance and maintain biological diversity by protecting critical Core Habitat while allowing development in other areas. The CVMSHCP sets Conservation Goals and Objectives to ensure conservation of the Covered Species and conserved natural communities in the CVMSHCP Reserve System. Protection of large areas of habitat across the Plan Area provides coverage for a variety of special-status biological resources including those on the project site and with potential to occur. If the project complies with CVMSHCP guidelines and the recommended measures outlined in section 6.0 are implemented, the project would be consistent with the goals and objectives of the CVMSHCP.

KPC COACHELLA PROJECT JURISDICTIONAL DELINEATION REPORT

ROCKS BIOLOGICAL CONSULTING

1 1 Introduction
Rocks Biological Consulting (RBC) conducted a formal jurisdictional delineation for the KPC Coachella Project (project) to identify areas that may be considered jurisdictional under the U.S.

Army Corps of Engineers (Corps) pursuant to Section 404 of the Clean Water Act; the Regional Water Quality Control Board (RWQCB) pursuant to Section 401 of the Clean Water Act and the Porter-Cologne Act; and streambed and riparian habitats under California Department of Fish and Wildlife (CDFW) pursuant to California Fish and Game Code (§1602). This information is necessary to evaluate estimated jurisdictional impacts and permit requirements associated with the project, can be used by the agencies to assess project conformance with state and federal regulations, and serves as a request for the Corps to complete an Approved Jurisdictional Determination (AJD) based on the information provided in this report. Furthermore, Appendix A provides a checklist of the information contained in this report in compliance with the Corps Los Angeles District’s Minimum Standards for Acceptance of Aquatic Resources Delineation Reports (Corps 2017b).

1.1 Project Location
The project site for the proposed project is located along the western foothills of the Little San Bernardino Mountains immediately north of Interstate 10 (I-10) and east of Coachella Canal Road within the City of Coachella and an unincorporated area of Riverside County, California (Figure 1). The Coachella Canal runs north to south through the westernmost portion of the project site. State Route 86 is located approximately two miles west of the project site.

The latitude and longitude of the approximate center of the site is 33.711629, -116.108462.

The project site sits on Township 5 South, Range 8 East, Sections 24, 25, 26, 27, and 28 and Township 5 South, Range 9 East, Section 30 within the Thermal Canyon and Indio 7.5-minute quadrangles, as mapped by the U.S. Geological Survey (USGS; Figure 2).

1.2 Project Description
The proposed project consists of a Specific Plan for a new master planned community located at the eastern entrance to the City of Coachella. The 2,800-acre project site will provide a mixture of land uses intended to create a cohesive entrance to the City of Coachella, with unique residential components that will be compatible with the surrounding existing and planned neighboring areas. The proposed project will provide additional commercial, residential, educational, employment, and recreational opportunities for residents and visitors within the City of Coachella, including a hotel and casino.

1.3 Regulatory Background
Several regulations have been established by federal, state, and local agencies to protect and conserve aquatic resources. The descriptions below provide a brief overview of agency regulations that may be applicable to the project. Regulatory agencies make the final determination of whether a project requires authorization pursuant to these regulations.

Item 25.

ROCKS BIOLOGICAL CONSULTING

2 1.3.1 Applicable Aquatic Resource Protection Regulations Clean Water Act
Pursuant to Section 404 of the Clean Water Act (33 U.S. Code [USC] § 1251 et seq.; CWA), the Corps is authorized to regulate any activity that would result in the discharge of dredged or fill material into waters of the U.S. (including wetlands), which include those waters listed in 33 Code of Federal Regulations (CFR) 328.3 (as amended at 80 Federal Register [FR] 37104, June 29, 2015; also referred to as the 2015 Clean Water Rule). The Corps, with oversight from the U.S. Environmental Protection Agency (USEPA), has the principal authority to issue CWA Section 404 permits. The Corps would require a Standard Individual Permit (SIP) for more than minimal impacts to waters of the U.S. as determined by the Corps. Projects with minimal individual and cumulative adverse effects on the environment may meet the conditions of an existing Nationwide Permit (NWP).

Under the 2015 Clean Water Rule applicable on the date of this report, the Corps defines waters of the U.S. as follows:
a. [T]he term “waters of the United States” means:
1) All waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide;
2) All interstate waters, including interstate wetlands; 3) The territorial seas;
4) All impoundments of waters otherwise identified as waters of the United States under this section;
5) All tributaries, as defined in paragraph (c)(3) of this section, of waters identified in paragraphs (a)(1) through (3) of this section; and
6) All waters adjacent to a water identified in paragraphs (a)(1) through (5) of this section, including wetlands, ponds, lakes, oxbows, impoundments, and similar waters.

Additionally, under the 2015 Clean Water Rule, waters of the U.S. also include all waters noted in 33 CFR 328.3 (a)(7) (i.e., prairie potholes, Carolina bays and Delmarva bays, pocosins, western vernal pools, and Texas coastal prairie wetlands) and all waters noted in 33 CFR 328.3 (a)(8) (i.e., “waters located within the 100-year floodplain” of a water identified in 33 CFR 328.3 (a)(1) through (3) and all waters “within 4,000 feet of the high tide line or OHWM” of a water identified in 33 CFR 328.3 (a)(1) through (5)) where they are determined to have a significant nexus to a water identified above in 33 CFR 328.3 (a)(1) through (a)(3).

A repeal of the 2015 Clean Water Rule was published on October 22, 2019. As a result, the following definition of waters of the U.S., per pre-2015 regulations, is anticipated to go into effect on December 23, 2019 per 33 CFR 328.3 (51 FR 41217; 53 FR 20764). a. The term waters of the United States means:

Item 25.

KPC COACHELLA PROJECT JURISDICTIONAL DELINEATION REPORT

ROCKS BIOLOGICAL CONSULTING

3 1) All waters which are currently used, or were used in the past or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide;
2) All interstate waters including interstate wetlands; 3) All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters:
i. Which are or could be used by interstate or foreign travelers for recreational or other purposes; or
ii. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or
iii. Which are used or could be used for industrial purpose by industries in interstate commerce;
4) All impoundments of waters otherwise defined as waters of the United States under the definition;
5) Tributaries of waters identified in paragraphs (a)(1) through (4) of this section; 6) The territorial seas;
7) Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs (a)(1) through (6) of this section.

The pre-2015 definition of waters of the U.S. was further defined by two Supreme Court cases, namely the 2001 Solid Waste Agency of Northern Cook County decision (Solid Waste Agency of Northern Cook County [SWANCC] v. U.S. Army Corps of Engineers et al., 2001) and the 2006 Rapanos decisions (Rapanos v. United States, 2006).

A water quality certification or waiver pursuant to Section 401 of the CWA is required for all Section 404 permitted actions. The RWQCB, a division of the State Water Resources Control Board, provides oversight of the 401-certification process in California. The RWQCB is required to provide “certification that there is reasonable assurance that an activity that may result in the discharge to waters of the United States will not violate water quality standards.” Water Quality Certification must be based on the finding that proposed discharge will comply with applicable water quality standards.

The National Pollutant Discharge Elimination System (NPDES) is the permitting program for discharge of pollutants into surface waters of the U.S. under Section 402 of the CWA.

Porter-Cologne Water Quality Control Act
The Porter-Cologne Water Quality Control Act (Water Code Section 13000 et seq.) provides for statewide coordination of water quality regulations. The State Water Resources Control Board was established as the statewide authority and nine separate RWQCBs were developed to oversee water quality on a day-to-day basis. The RWQCB is the primary agency responsible for protecting water quality in California. As discussed above, the RWQCB regulates discharges to

Item 25.

KPC COACHELLA PROJECT JURISDICTIONAL DELINEATION REPORT

ROCKS BIOLOGICAL CONSULTING

4 surface waters under the federal CWA. In addition, the RWQCB is responsible for administering the Porter-Cologne Water Quality Control Act.

Pursuant to the Porter-Cologne Water Quality Control Act, the state is given authority to regulate waters of the state, which are defined as any surface water or groundwater, including saline waters. As such, any person proposing to discharge waste into a water body that could affect its water quality must first file a Report of Waste Discharge if Section 404 is not required for the activity. “Waste” is partially defined as any waste substance associated with human habitation, including fill material discharged into water bodies.

California Fish and Game Code Section 1600-1602
Pursuant to Division 2, Chapter 6, Section 1602 of the California Fish and Game Code (CFGC), CDFW regulates all diversions, obstructions, or changes to the natural flow or bed, channel or bank of any river, stream or lake that supports fish or wildlife. A Notification of Lake or Streambed Alteration must be submitted to CDFW for “any activity that may substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake.” CDFW has jurisdiction over riparian habitats associated with watercourses and wetland habitats supported by a river, lake, or stream. Jurisdictional waters are delineated by the outer edge of riparian vegetation (i.e., drip line) or at the top of the bank of streams or lakes, whichever is wider. CDFW jurisdiction does not include tidal areas or isolated resources. CDFW reviews the proposed actions and, if necessary, submits (to the applicant) a proposal that includes measures to protect affected fish and wildlife resources. The final proposal that is mutually agreed upon by CDFW and applicant is the Lake or Streambed Alteration Agreement.

Prior to the on-site delineation, field maps were created using a Geographic Information System (GIS) and a color aerial photograph at a 1:400 scale. RBC staff also reviewed U.S. Geological Survey (USGS) National Hydrography Dataset (NHD) and topography data (Figure 2) and U.S.

Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) data (Figure 4) to further determine the potential locations of jurisdictional aquatic resources. Google Earth was also utilized to assess current and historic presence or absence of flow in the project area.

RBC regulatory specialists Shanti Santulli, Emily Trevino, and Sarah Krejca conducted the jurisdictional delineation field visit from May 7, 2019 to May 10, 2019. Shanti Santulli and Brenda Bennett conducted an additional jurisdictional delineation field visit from October 29, 2019 to October 30, 2019. Field survey conditions are shown below in Table 1.

The project survey area included the proposed project area with a 100-foot buffer for a total of approximately 2,970 acres. Field staff utilized modeled hydrology data/figures for the project survey area provided by the project hydrologist, Q3 Consulting, to assist in focusing the field effort within the large project survey area (Appendix B). Areas with depressions, drainage patterns, and/or wetland vegetation within the project impact area were evaluated for potential jurisdictional status, with focus on the presence of defined channels and/or wetland vegetation, soils, and hydrology. Field staff examined potential Corps- and RWQCB-jurisdictional wetland areas using the routine determination methods set forth in Part IV, Section D, Subsection 2 of the Corps 1987 Wetland Delineation Manual (Wetland Manual) (Environmental Laboratory 1987) and the 2008 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region Version 2.0 (Arid West Supplement) (Corps 2008a).

6 Areas that met the three parameters per the Arid West Supplement (i.e., hydrophytic vegetation, hydric soils, and wetland hydrology) were considered wetland waters of the U.S./State. RBC staff based wetland plant indicator status (i.e., Obligate [OBL], occurs 99+% in wetlands; Facultative Wetland [FACW], occurs 67-99% in wetlands; Facultative [FAC], occurs 34-66% in wetlands; Facultative Upland [FACU], occurs 1-33% in wetlands; Upland [UPL], occurs 99+% in uplands) on the National Wetland Plant List (NWPL; Corps 2016) and hydric soils indicators on Field Indicators of Hydric Soils in the United States, Version 8.2 (NRCS 2018). Soil chromas were identified in the field according to Munsell's Soil Color Charts (Munsell Color 2015) and using protocols per the Arid West Supplement.

Note that in April 2019 the State Water Resources Control Board adopted the State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State (the Procedures) which will become effective on May 28, 2020, nine months after the Office of Administrative Law approved the Procedures on August 28, 2019. As detailed in the Procedures, the State Water Resources Control Board and RWQCBs (Water Boards) define a wetland as follows: “An area is wetland if, under normal circumstances, (1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or shallow surface water, or both; (2) the duration of such saturation is sufficient to cause anaerobic conditions in the upper substrate; and (3) the area’s vegetation is dominated by hydrophytes or the area lacks vegetation.”
Although the Procedures are not yet applicable to this project, the Procedures provide that RWQCB shall rely on a wetland area delineation from a final aquatic resource report verified by the Corps to determine the extent of wetland waters of the State. If any potential wetland areas have not been delineated in a final aquatic resources report verified by the Corps, the limits of such potential wetland waters of the State shall be identified using the same wetland delineation methods per the Corps as described above, except that a lack of vegetation (i.e., less than 5 percent areal coverage of plants during the peak of the growing season) does not preclude an area from meeting the definition of a wetland waters of the State.

Lateral limits of potential non-wetland waters of the U.S./State for the Corps and RWQCB, respectively, were identified using field indicators of an ordinary high water mark (OHWM). An OHWM is defined in 33 CFR 329.11 as “that line on the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the presence of litter or debris; or other appropriate means that consider the characteristics of the surrounding areas.” RBC staff used A Field Guide to the Identification of the Ordinary High Water Mark in the Arid West Region of the Western United States (OHWM Field Guide; Corps 2008b) to estimate the extent of an OHWM in the field. For each feature exhibiting the potential presence of an OHWM, RBC completed a 2010 Arid West Ephemeral and Intermittent Streams OHWM Datasheet following the guidance provided in the Updated Datasheet for the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States (OHWM Datasheet; Corps 2010). Per the 2010 OHWM Datasheet, common indicators of an OHWM include a break in slope (i.e., abrupt cut in bank slope created by hydrogeomorphic processes across the landscape), changes in average sediment texture between floodplain units (i.e., low-flow, active floodplain, low terrace), and changes in vegetation species and/or cover between floodplain units.

7 CDFW potential jurisdictional boundaries were determined based on the presence of streambed and associated riparian habitat and/or wetland areas. Streambeds considered within CDFW jurisdiction were delineated based on the definition of streambed as "a body of water that flows at least periodically or intermittently through a bed or channel having banks and supporting fish or other aquatic life. This includes watercourses having a surface or subsurface flow that supports riparian vegetation" (Title 14, Section 1.72). Riparian habitat refers to vegetation and habitat associated with a stream. The CDFW jurisdictional habitat includes all riparian shrub or tree canopy that may extend beyond the banks of a stream. Isolated riparian habitat (i.e., where riparian vegetation did not appear associated with an ephemeral wash) were not considered CDFW-jurisdictional. CDFW follows the USFWS wetland definition and classification system, which defines a wetland as transitional land between terrestrial and aquatic systems having one or more of the following attributes: “(1) at least periodically, the land supports predominantly hydrophytes; (2) the substrate is predominantly undrained hydric soil; and (3) the substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season of each year” (USFWS 1979). A wetland is presumed when all three attributes are present; if less than three attributes are present the presumption of a wetland must be supported by “the demonstrable use of wetland areas by wetland associated fish or wildlife resources, related biological activity, and wetland habitat values” (CFGC 1994).

Furthermore, to assist in assessing CDFW streambed limits in desert areas, RBC staff utilized the methods outlined in the Mapping Episodic Stream Activity (MESA) Field Guide (Vyverberg et al. 2013). The MESA Field Guide was developed to describe methodology for delineating episodic streams within the arid and semi-arid California desert regions. The MESA guidelines indicate streams extend beyond an OHWM and can consist of associated features such as lowflow, active, and braided channels and banks associated with islands, secondary channels, and streambed within the bounds of a larger channel complex defined as the “watercourse” (Vyverberg et al. 2013).

While in the field, potentially jurisdictional features were recorded using a hand-held Global Positioning System (GPS) unit with a level of accuracy ranging from four to 20 feet. RBC staff refined the data using aerial photographs and topo maps with two-foot contours to ensure accuracy. Plants were identified according to The Jepson Manual 2nd edition (Baldwin et al. 2012). A plant list compiled by RBC biologists during the May 1, 2, 8, and 9, 2019 field surveys, with each plant’s wetland indicator status per the NWPL, is included as Appendix C. RBC staff used the vegetation community classifications mapped by RBC biologists during the May 1, 2, 8, and 9, 2019 field surveys. The vegetation community classifications follow Holland (1986) and nomenclature follows Jepson eFlora (Jepson Flora Project 2019).

All figures generated for this jurisdictional delineation report follow the Corps’ Updated Map and Drawing Standards for the South Pacific Division Regulatory Program (Corps 2016). 3 Results

3.1 Topography
The proposed project area consists of steep, hilly terrain associated with the Little San Bernardino foothills with interspersed, flatter alluvial fans and desert washes. Elevations within the project area range from 512 to 1,420 feet above mean sea level (Figure 2).

8 3.2 Watershed
The proposed project area is within the Whitewater River Hydrologic Unit Code [HUC] 8 (18100201), Middle Whitewater River HUC 10 (1810020107), and City of Indio – Whitewater River HUC 12 (181002010705) watersheds (Figure 3).

The Whitewater River watershed is approximately 4,500 square miles. The Whitewater River headwaters originate in the San Bernardino Mountains, and continue southeast to the Salton Sea and Sonoran Desert (Riverside County Watershed Protection [RCWP] 2018). The Middle Whitewater River HUC 10 encompasses approximately 177 square miles and the City of Indio – Whitewater River HUC 12 encompasses approximately 74 square miles.

3.3 Hydrology
USGS NHD maps several “blue-line streams” within the project survey area, which are all ephemeral washes (Figure 2). USGS NHD also maps the Coachella Canal as a “green-line canal/ditch,” along the western boundary of the project boundary. USFWS NWI maps several features with a designation of “Riverine” and two features with a designation of “Freshwater Forested/Shrub Wetland” within the project boundary and survey area (Figure 4). The two features designated as “Freshwater Forested/Shrub Wetland” appear to receive flows from a storm drain outfall (Figure 5).

The Coachella Canal, which is partially located on site, flows in the northwesterly direction, continuing into Lake Cahuilla, then the Whitewater River, which ultimately connects to the Salton Sea.

The known hydrologic sources for the other observed on-site aquatic features (i.e., ephemeral washes), discussed further below, are direct precipitation, including surface flows from the higher elevations, and from the agricultural operation runoff to the north of the western portion of the project survey area. Based on field observations, the ephemeral washes on site are topographically disconnected from and cannot connect to the Coachella Canal given the presence of a large 40- to 50-foot high levee along the north bank of the canal. On-site aquatic features generally flow in a southwesterly direction through the project survey area. Several onsite aquatic features are confined and/or redirected by several manmade berms, as shown on Figure 5. On-site ephemeral washes eventually flow toward the southern boundary of the property where they are directed under the I-10 through a number of culverts and undercrossings to the undeveloped property to the south. The La Entrada Specific Plan (La Entrada) is a master-planned residential community slated to occur on the undeveloped property to the south of the KPC Coachella property. Because any flows that leave the KPC Coachella property end up on the La Entrada site, RBC reviewed the La Entrada Specific Plan, City of Coachella, California, Delineation of State and Federal Jurisdictional Waters (La Entrada JDR; RBF Consulting 2013) for information regarding the hydrology in the area and downstream connectivity.

Based on the La Entrada JDR, flows from the La Entrada site are directed southwest to an evacuation outlet (i.e., culvert) under the Coachella Canal which serves as the only floodconveyance facility for flows that continue south/downstream. After travelling through the evacuation outlet, flows are conveyed through Wasteway Channel No. 2 for approximately 2.2 miles before discharging into the Whitewater River. Based on hydrologic studies (conducted by the same project hydrologists for both the La Entrada site and the KPC Coachella property), it

9 would take nearly a 50-year storm event for waters to flow from the La Entrada site through the evacuation outlet (RBF Consulting 2013). Since the on-site features that flow under the I-10 from the KPC Coachella property are upstream and discharge onto the La Entrada site, Q3 Consulting determined that a similar assumption can be made for the KPC Coachella property.

That is, the KPC Coachella Project will not change the analyzed hydrologic condition per the La Entrada JDR; therefore, flows from the KPC Coachella property would not discharge to the Whitewater River during a storm event below the 50-year annual return frequency (John McCarthy [Q3 Consulting], personal communication, June 14, 2019). Section 3.8 provides additional information regarding downstream connectivity of the on-site ephemeral washes.

RBC utilized the Natural Resources Conservation Service (NRCS) Agricultural Applied Climate Information System (AgACIS) database for the Indio Fire Station, California National Weather Service (NWS) station in Riverside County to access precipitation and Wetlands (WETS) Climate Tables data. WETS tables are utilized to define the range of normal precipitation and growing season for NWS stations. WETS tables define the “normal” range at the 30th and 70th percentile of all the data in the precipitation record for that station. RBC requested data for the past 30 years (1988-2019) to provide the pertinent pre-site visit precipitation data. Appendix D and Table 2 utilize the Indio Fire Station, California station due to its comprehensive historical data and proximity to the project site (i.e., approximately 3 miles northwest).

Riverside County is characterized by hot, dry summers and mild, relatively wet winters. The Indio Fire Station, California NWS station lists the highest averaged daily maximum temperature over the past 30 years as 106.9o
F for the month of July and the lowest averaged daily minimum temperature over the past 30 years as 44.2o
F for the month of December (NRCS 2019). The
NRCS does not calculate a growing season length for this station since insufficient data is available for the 30-year period.

Table 2 describes the estimated monthly total precipitation for the proposed project area from November 2018 to October 2019 to provide the pertinent pre-site visit precipitation data from the NRCS AgACIS database for the Indio Fire Station, California NWS station.

10 3.4 Soils
The NRCS Web Soil Survey does not provide soils data for the eastern portion of the project area. Based on the NRCS map of the portion of the project area for which soils data is available (Figure 4), the following soils occur within the project site boundary and are described below per the USDA’s Official Soil Series Description and Series Classification database (NRCS n.d. a) and the Soil Survey of Riverside County, California, Coachella Valley Area (USDA 1980):

Badland – Badland consists of very steep, excessively drained, severely eroded areas broken by numerous deeply entrenched channels and steep side drainages with raw bands or freshly exposed material. Badland is composed of slightly consolidated sandy alluvium capped with a very thin mantle of loose sand and is primarily used for watershed, wildlife habitat, and recreation. The NRCS does not list Badland, which occurs on site, as hydric.

Borrow pits – Borrow pits result from the removal of soil and underlying material. The NRCS lists Borrow pits, which occurs on site, as hydric under Criteria 3, meaning this soil map unit contains “components that are frequently ponded for long duration or very long duration during the growing season that: a) Based on the range of characteristics for the soil series, will at least in part meet one or more Field Indicators of Hydric Soils in the United States, or b) Show evidence that the soil meets the definition of a hydric soil” (NRCS n.d. b).

Carrizo stony sand, 2 to 9 percent slopes – The Carrizo series consists of very deep, excessively drained soils formed in mixed igneous alluvium. These soils are found primarily on numerous landforms on flood plains, fan piedmonts, and bolson floors in the Mojave Desert of southeastern California, western Arizona, and southern Nevada. These soils are primarily used for rangeland, recreation, and wildlife habitat. The NRCS does not list Carrizo stony sand, 2 to 9 percent slopes, which occurs within the 50-foot buffer and possibly occurs within the eastern portion of the project site, as hydric.

Carsitas gravelly sand, 0 to 9 percent slopes – The Carsitas series consists of very deep, somewhat excessively drained soils formed in alluvium from granitoid and/or gneissic rocks.

These soils are found primarily on alluvial fans, fan aprons, valley fills, and dissected remnants of alluvial fans and in drainageways in the Colorado Desert of southeastern California. These soils are primarily used for watershed, wildlife habitat, and recreation. The NRCS lists Carsitas gravelly sand, 0 to 9 percent slopes, which occurs on site, as hydric under Criteria 4, meaning this soil map unit contains “components that are frequently ponded for long duration or very long duration during the growing season that: a) Based on the range of characteristics for the soil series, will at least in part meet one or more Field Indicators of Hydric Soils in the United States, or b) Show evidence that the soil meets the definition of a hydric soil” (NRCS n.d. b).

Carsitas cobbly sand, 2 to 9 percent slopes – The Carsitas series consists of very deep, somewhat excessively drained soils formed in alluvium from granitoid and/or gneissic rocks.

These soils are found primarily on alluvial fans, fan aprons, valley fills, and dissected remnants of alluvial fans and in drainageways in the Colorado Desert of southeastern California. These soils are primarily used for watershed, wildlife habitat, and recreation. The NRCS lists Carsitas cobbly sand, 2 to 9 percent slopes, which occurs on site, as hydric under Criteria 4, meaning this soil map unit contains “components that are frequently ponded for long duration or very long duration during the growing season that: a) Based on the range of characteristics for the soil

11 series, will at least in part meet one or more Field Indicators of Hydric Soils in the United States, or b) Show evidence that the soil meets the definition of a hydric soil” (NRCS n.d. b).

Chuckawalla very gravelly sandy clay loam, 2 to 5 percent slopes – The Chuckawalla series consists of very deep, well drained soils formed in stratified mixed alluvium. These soils are found primarily on fan terraces in low desert areas of southern California and southwestern Arizona, and used for recreation and watershed. The NRCS does not list Chuckawalla very gravelly sandy clay loam, 2 to 5 percent slopes, which occurs on site, as hydric.

Myoma fine sand, 0 to 5 percent slopes – The Myoma series consists of moderately alkaline fine and very fine sands to a depth of about 31 inches, below 31 inches they are strongly alkaline very fine sands. These soils are found in southern California and primarily used for growing citrus fruits, grapes, alfalfa, dates, and truck crops under irrigation. The NRCS lists Myoma fine sand, 0 to 5 percent slopes, which occurs on site, as hydric under Criteria 4, meaning this soil map unit contains “components that are frequently ponded for long duration or very long duration during the growing season that: a) Based on the range of characteristics for the soil series, will at least in part meet one or more Field Indicators of Hydric Soils in the United States, or b) Show evidence that the soil meets the definition of a hydric soil” (NRCS n.d. b).

As stated in the Arid West Supplement, RBC used the hydric soils list as a tool and made final hydric soils determinations based on field-collected data at representative wetland delineation sample points deemed appropriate on site as recorded on the attached Arid West Wetland Delineation Forms (Appendix E) discussed further below.

3.5 Vegetation
Based on field surveys conducted by RBC biologists on April 13 and May 1, 2, 8, and 9, 2019, the following vegetation communities occur within the project survey area.

Agricultural Land – Agricultural land within the project survey area (3.84 acres) is under current cultivation. Agricultural areas are both disturbed and irrigated and provide little habitat for native plant and wildlife species. Agicultural land occurs in the western portion of the project survey area.

Desert Wash Scrub/Sonoran Creosote Bush Scrub – An intermixing of two vegetation types; desert wash scrub and Sonoran creosote bush scrub occurs across large areas of the project survey area most often within, but not limited to, the numerous ephemeral washes on site. These washes contain a mix of species associated with both vegetation types including desert-lavender (Condea emoryi), smoke tree (Psorothamnus spinosus), indigo bush (Psorothamnus schottii), desert bird-of-paradise (Hoffmannseggia microphylla), rush sweet-bush (Bebbia juncea var. aspera), catclaw acacia (Senegalia greggii), and occasional blue palo verde (Parkinsonia florida), as well as creosote bush (Larrea tridentata) and white bursage (Ambrosia dumosa).

Disturbed Habitat – Disturbed habitat within the project survey area (39.99 acres) consists primarily of bare soils and non-native species that are a result of human disturbance. Disturbed lands have been graded, cleared, or used to the point where the land cannot support native vegetation.

Disturbed areas occur mostly in the western portion of the project survey area adjacent to agricultural land.

ROCKS BIOLOGICAL CONSULTING

12 Mesquite Hummocks – Mesquite hummocks (1.28 acres) occur only on the western portion of the project survey area within the Coachella Valley Multiple Species Habitat Conservation Plan’s (CVMSHCP) East Indio Hills Conservation Area. Mesquite hummocks consist solely of mesquite (Prosopis glandulosa var. glandulosa) on a raised hummock of blown sand. This habitat is important for wildlife and has a stabilizing effect on sand dunes.

Sonoran Creosote Bush Scrub – Sonoran creosote bush scrub (1,955.75) is the dominant habitat type within the project survey area. This community occurs on upland slopes, hills, bajadas, and alluvial fans, and within the ephemeral washes on site. Sonoran creosote bush scrub is dominated by widely-spaced stands of creosote bush with open soil, annual plants, and other shrubs occurring between creosote bush shrubs. Other common shrubs within this community include white bursage, brittlebush (Encelia farinose), and desert-holly (Atriplex hymenelytra). Observation of short-lived annual plant species was limited due to the timing of the field survey.

Tamarisk Scrub – Tamarisk scrub within the project survey area (1.10 acres) primarily consists of dense tamarisk (Tamarix ramosissima) shrubs. Tamarisk scrub typically occurs on sandy or gravelly soils within or in close proximity to washes or streams and often follows major anthropogenic disturbance. Tamarisk scrub occurs on the western portion of the project survey area in areas disturbed by both agriculture and construction of a water tower.

Table 3 provides vegetation community acreages within the project survey area (Figure 6).

Total 2,970.40

3.6 Features Observed
The project survey area consists of hilly desert land with many braided dry, sandy washes. The western portion of the project survey area also includes one earthen levee and five earthen berms which confine or redirect flows throughout the project survey area, as shown on Figure

5. As further supported by the aerial imagery analysis provided in Appendix F, the western portion of the project survey area was heavily manipulated between 1940 and 1953 with the construction of the Coachella Canal, an adjacent earthen levee, and several earthen berms to obstruct or redirect flows. The locations of the earthen berms changed throughout the years, with the present-day locations first appearing in 2002 aerials (Appendix F).

Estimated jurisdictional features observed within the project survey area during the formal jurisdictional delineation field effort, further discussed in Section 3.7, include Feature (F) 1 to F16

Item 25.

ROCKS BIOLOGICAL CONSULTING

13 (which includes F1 – Disturbed Ephemeral Drainage Area, F1 – Tamarisk Scrub/Ephemeral Drainage, F1 – Tamarisk Scrub, and F13 – Tamarisk Scrub in this report unless otherwise specified) and the Coachella Canal (Figure 5, 5A-5J). Each named/numbered feature represents a separate watercourse, and as such, includes all functionally related and connected singlethread channels, compound channels, braided channels, and floodplains. Features that may connect outside of the project survey boundary were not deemed to be functionally related or connected for purposes of naming each on-site feature. Some on-site delineated features may not be jurisdictional by an agency or agencies as detailed in Section 3.8.

RBC investigated two wetland sample points to determine the presence or absence of federally jurisdictional wetlands (Figure 5, 5A-5J; Appendix E) in areas displaying potential wetland landscape position (e.g., minimal slope and/or depressional) and hydrology (e.g., surface soil cracks). RBC also completed five OHWM Datasheets at representative sample points in areas observed to have defined drainage patterns in the project survey area since there were multiple dry washes (i.e., features) with similar hydrology/OHWM characteristics in the project survey area (Figure 5, 5A-5J; Appendix E). Note that RBC is able to provide the Figure 5 series, which shows the estimated jurisdictional resources on site, at a smaller scale, if requested by the resource agencies.

Wetland Sample Point (WSP 1) was taken within the relatively flat F1 – Disturbed Ephemeral Drainage Area in an area primarily dominated by nettle-leaf goosefoot (Chenopodium murale; FACU) blue palo verde (Not Listed [NL]/UPL), and London rocket (Sisymbrium irio; NL/UPL).

WSP 1 met the wetland hydrology parameter based on the presence of surface soil cracks; the hydrophytic vegetation and hydric soils parameters, however, were not met (Appendix E). Note that there was also evidence of recent surface manipulation within this area due to the presence of large tire tracks; therefore, the vegetation and top soil layer appeared disturbed.

WSP 2 was taken within F1 – Tamarisk Scrub/Ephemeral Drainage in an area that was primarily dominated by tamarisk/salt cedar (Tamarix sp.). The Tamarix sp. was likely Tamarix ramosissima (NL/UPL), but is understood to hybridize and function similarly to Tamarix chinensis (FAC). Assuming Tamarix chinensis as the dominant vegetation, WSP 2 met the hydrophytic vegetation parameter; the wetland hydrology and hydric soils parameters, however, were not met (Appendix E).

RBC determined the presence of an OHWM and bed and bank in the following representative locations within the project survey area: three locations within F8 (OHWM 1, 3, and 4), one location within F1 (OHWM 2), and one location within F3 (OHWM 5). OHWM 2 and 4 were taken as representative OHWM data points for the large watercourses (i.e., F4, F8, and F16); OHWM 1, 3, and 5 were taken as representative OHWM data points for the smaller watercourses and tributaries (i.e., F1 - F3, F5 - F7, and F9 - F15).

Table G-1 within Appendix G provides a summary of the existing characteristics of each of the observed on-site aquatic resources, F1 to F16 and the Coachella Canal. Overall, the watercourses observed on site consisted of generally unvegetated, dry, braided low-flow channels within sparsely vegetated active floodplains, which transitioned to low terraces generally dominated by creosote bush (NL/UPL), or pebble pincushion (Chaenactis carphoclinia var. carphoclinia; NL/UPL). Sediment was generally finer in the low-flow channels than within the active floodplains. The features varied in width from 3 to 1,650 feet (Appendix G, Table G-1).

RBC utilized on-site field observations and a kmz file of the GIS limits of the jurisdictional

14 delineation site visit to define estimated minimum and maximum feature limits on Google Earth imagery. Indicators of an OHWM for the observed features within the project survey area included a change in vegetation cover, vegetation species, and sediment texture between the active floodplain and upland areas as well as a small break in slope along the active channel (Appendix E, OHWM 1-5). The extent of the mapped OHWM also matched the delineated bed and bank of each feature (Figure 5). Please note that some of the islands located within a delineated feature were CDFW-jurisdictional areas that would not have been included within the OHWM per the OHWM Field Guide; however, calling out CDFW-jurisdictional islands between the delineated washes would have taken a substantial effort so RBC included these CDFWjurisdictional islands as part of the OHWM.

Note that F1 – Disturbed Ephemeral Drainage Area is located within the CVMSHCP’s East Indio Hills Conservation Area, which is part of the watershed for mesquite hummocks. This area also has a general plan land use designation of Open Space and will be preserved as open space with project implementation.

Appendix H provides site photographs of the features and Figure 7 displays representative photo points.

3.7 Jurisdictional Resources and Analyses
The Coachella Canal would be considered a Corps-jurisdictional, non-wetland waters of the U.S. as a tributary (i.e., 33 CFR 328.3(a)(5)) to the Whitewater River and ultimately the Salton Sea. However, all other on-site features would not be considered Corps-jurisdictional as detailed in Section 3.8 below.

The Coachella Canal and F1 to F16 (excluding F1 – Tamarisk Scrub and F13 – Tamarisk Scrub) would be considered non-wetland waters of the State/surface waters per the RWQCB. RBC also expects the Coachella Canal and F1 to F16 would be considered CDFW streambed, associated riparian habitat, and/or watercourse as defined by the MESA Guidelines. Generally, areas deemed as jurisdictional by the RWQCB and CDFW consisted of watercourses comprised of ephemeral desert wash.

Table 4, below, provides the total acreages of estimated jurisdictional resources. Tables I-1, I-2, and I-3 in Appendix I provide additional information regarding the Coachella Canal and F1 through F16 including acreages, linear feet, and dominant vegetation. None of the features within the project survey area met the three parameters per the Arid West Supplement; therefore, no Corps-/RWQCB-jurisdictional wetlands occur within the project survey area.

Although WSP 1 taken within F1 – Disturbed Ephemeral Drainage did meet the wetland hydrology parameter based on the presence of surface soil cracks, the area does not support any wetland associated fish or wildlife resources, related biological activity, or wetland habitat values. Similarly, although WSP 2 taken within F1 – Tamarisk Scrub/Ephemeral Drainage did meet the hydrophytic vegetation parameter, based on the assumption that the Tamarix ramosissima, an NL/UPL species, was functioning similar to Tamarix chinensis, a FAC species, the area does not support any wetland associated fish or wildlife resources, related biological activity, or wetland habitat values. Further, none of the other features within the project survey area exhibited any of the three wetland parameters. Therefore, RBC expects that none of the features within the project survey area would be considered jurisidictional wetlands per CDFW.

15 As estimated overall, the project survey area supports 2.72 acres (2,957 linear feet) of Corpsjurisdictional, non-wetland waters of the U.S.; 637.37 acres (282,372 linear feet) of RWQCBjurisdictional, non-wetland waters of the State; and 637.57 acres (282,372 linear feet) of CDFWjurisdictional, non-wetland streambed, associated riparian habitat, and/or watercourse as summarized in Table 4 below. Appendix I, Tables I-1, I-2, and I-3, provide details on the delineated on-site features per agency jurisdiction.

Section 3.8 provides details on why F1 to are not expected to be considered jurisdictional by the Corps.

3.8 Non-Jurisdictional Resources and Analyses
RBC anticipates this report will be submitted to the agencies after changes to the Corps’ waters of the U.S. regulations go into effect on December 23, 2019 (i.e., pre-2015 regulations and guidance will apply instead of the current 2015 Clean Water Rule). Furthermore, a revised definition of waters of the U.S. is anticipated to be published as early as January 2020, but its effective date, if applicable, remains uncertain. Given the above, for purposes of this jurisdictional delineation report, the non-jurisdictional status of F1 to F16 is analyzed under the pre-2015 regulations and guidance that will be effective on December 23, 2019.

While potentially jurisidictional per CDFW and/or the RWQCB, F1 to F16 (including F1 – Disturbed Ephemeral Drainage Area, F1 – Tamarisk Scrub/Ephemeral Drainage, and riparian habitat areas F1 – Tamarisk Scrub and F13 – Tamarisk Scrub) located within the project survey area do not meet the Corps’ definition of waters of the U.S. per pre-2015 regulations and guidance.F1 to F16 either terminate on site or ultimately flow to the southern boundary of the proposed project site where they are directed under the I-10 through a number of culverts and undercrossings to the undeveloped property to the south. In general, flows are isolated on this neighboring undeveloped property by the Coachella Canal.

Furthermore, as discussed above in Section 3.3 and based on hydrologic studies performed for the downstream La Entrada site and an AJD completed by the Corps in May 2018, flows from the La Entrada site are directed southwest to an evacuation outlet (i.e., culvert) under the Coachella Canal which serves as the only flood-conveyance facility for flows that continue south/downstream. After travelling through the evacuation outlet, flows are conveyed through Wasteway Channel No. 2 for approximately 2.2 miles before discharging into the Whitewater River. Runoff from the La Entrada site would not discharge through Wasteway Channel No. 2 to the Whitewater River for a storm event below the 50-year annual return frequency, which also

16 would apply to the ephemeral washes that flow from the KPC Coachella property onto the La Entrada site (John McCarthy [Q3 Consulting], personal communication, June 14, 2019). Flows that would reach the Whitewater River in at least a 50-year event would then travel approximately 13 miles before ultimately flowing into the Salton Sea. Given the above, flow events connecting the ephemeral washes on the KPC Coachella property to the Whitewater River are of such infrequent duration that they would only have a “speculative or insubstantial” effect on the “chemical, physical, or biological integrity” on the applicable traditionally navigable water (TNW), the Salton Sea.

Given the above rationale, F1 to F16 are not jurisdictional by the Corps as these ephemeral washes and riparian areas do not meet the criteria of jurisdictional waters per 33 CFR 328.3(a)(1) – (a)(7) (51 FR 41217; 53 FR 20764) and do not have significant nexus analysis to the nearest TNW, the Salton Sea. Table I-4 in Appendix I provides additional information regarding those features RBC expects the Corps would not deem jurisdictional.

Additionally, F1 – Tamarisk Scrub and F13 – Tamarisk Scrub are not jurisdictional by the RWQCB as these features are associated riparian habitat not considered non-wetland or wetland waters of the State/surface waters. Table I-5 in Appendix I provides additional information regarding those features RBC expects the RWQCB would not deem jurisdictional.

Appendix L includes the ORM Bulk Upload Aquatic Resources or Consolidated Excel spreadsheet.
4 Conclusion
Based on RBC’s field and desktop analysis of the project survey area, RBC expects that the Coachella Canal would be considered a Corps-jurisdictional, non-wetland waters of the U.S. (Appendix I, Table I-1); an RWQCB-jurisditional, non-wetland waters of the State/surface waters (Appendix I, Table I-2); and a CDFW-jurisdictional, non-wetland streambed and/or watercourse (Appendix I, Table I-3).

F1 to F16 would not be considered jurisdictional by the Corps (Appendix I, Table I-4). F1 to F16 (excluding F1 – Tamarisk Scrub and F13 – Tamarisk Scrub) would be considered RWQCBjurisdictional non-wetland waters of the State/surface waters (Appendix I, Table I-2), while F1 – Tamarisk Scrub and F13 – Tamarisk Scrub would not be considered jurisdictional by the RWQCB as these features are associated riparian habitat not considered non-wetland or wetland waters of the State/surface waters (Appendix I, Table I-5). F1 to F16 would be considered CDFW-jurisdictional, non-wetland streambed, associated riparian habitat, and/or watercourse (Appendix I, Table I-3).

Assuming the Corps finalizes the AJD and concludes that F1 to F16 are not jurisdictional, no Corps permitting would be required for the project assuming the proposed project will not impact the Coachella Canal. Impacts on jurisdictional features per other agencies (if deemed jurisdictional) would require Waste Discharge Requirements (WDR) from RWQCB and a Streambed Alteration Agreement (SAA) from CDFW. The RWQCB and/or CDFW may also require a functional assessment (e.g., California Rapid Assessment Method [CRAM]) to quantitatively estimate the stream condition for the evaluation of the proposed project.

Additionally, compensatory mitigation would be required by the regulatory agencies to offset the proposed project impacts.

17 Please note that the applicable agencies will make final jurisdictional determinations. RBC recommends early coordination with the resource agencies to determine the final jurisdictional boundaries, applicable permitting processes, compensatory mitigation requirements, and other potential permitting issues specific to the proposed project. Agency representatives may request to access the site to field-verify the results of this jurisdictional delineation report with the project applicant, or a designated representative.

The information provided in this report should remain valid for up to five years from the date of the field effort for the jurisdictional delineation unless site conditions change substantially, or a regulatory agency requires an updated report.

Item 25.

CHECKLIST: MINIMUM STANDARDS FOR ACCEPTANCE OF AQUATIC RESOURCES DELINEATION REPORTS, LOS ANGELES DISTRICT REGULATORY DIVISION, USACE, MARCH 16, 2017 1 REPORT SECTION/

PAGE NUMBER MINIMUM STANDARDS FOR ACCEPTANCE OF AQUATIC RESOURCES DELINEATION REPORTS ADDITIONAL NOTES Section 1; Appendix J
JD REQUEST AND FORMS: A cover letter indicating whether you are requesting a jurisdictional determination (JD). If you are requesting a JD, you must complete, sign, and return the Request for Corps Jurisdictional Determination (JD) sheet. For preliminary jurisdictional determinations the Preliminary Jurisdictional Determination Form must be signed and submitted.

Section 1.4 CONTACT INFORMATION: Contact information for the applicant(s), property owner(s), and agent(s).

N/A
SITE ACCESS: If the property owner or their representatives will not accompany the Corps to the site, a signed statement from the property owner(s) allowing Corps personnel to enter the property and to collect samples during normal business hours. If the property lacks direct access by public roads (in other words, access requires passage through private property not owned by the applicant), the owner or proponent must obtain permission from the adjacent property owner(s) to provide access for Corps personnel.

Property
owner and/or
representatives
will
accompany
the Corps for a
site visit upon
request.

Section 1.1 LOCATION: Directions to the survey area, an address (if available) and one or more set of geographic coordinates expressed in decimal degrees.

Section 2,
Paragraphs 3 and 7
DELINEATION MANUAL CONFIRMATION: A statement confirming the delineation has been conducted in accordance with the 1987 Corps of Engineers Wetlands Delineation Manual and applicable regional supplement(s). The regional supplement(s) used must be identified. For OHWM delineations, a statement must be included confirming the use of the OHWM field guide or that it is not applicable.

Section 3.6
AQUATIC RESOURCE(S) DESCRIPTION: A narrative describing all aquatic resources on-site and an explanation of the mapped boundaries and any complex transition zones. If the site contains resources that only meet one or two of the three wetland criteria or do not exhibit a clear OHWM, describe the rationale for their inclusion or exclusion from the delineation. Also explain if any erosional features, upland swales, ditches and other potential aquatic features were considered but not included in the delineation.

Figure 5; Appendix G,
Table G-1; Appendix I,
Tables I-1, I-2, I-3, I-4,
I-5
AQUATIC RESOURCE MAPPING AND ACREAGE: Map the outside survey boundary, total extent of aquatic and proposed non-aquatic features, type of feature(s) (waters of the United States or wetland), and include the total acreage for each polygon.

Section 2,
Paragraph 2; Table 1 FIELD WORK DATES: Date(s) field work was completed.

Appendix G, Table G1; Appendix I, Tables
I-1, I-2, I-3, I-4, I-5
AQUATIC RESOURCE TABLE: A table listing all aquatic resources. The table must include the name of each aquatic resource (actual or arbitrary), its Cowardin type, acreage, summary of OHWM/wetland presence, dominant vegetation for each, and location (latitude/longitude in decimal degrees). For linear features, the table must show both acreage and linear feet as well as channel measurements (active channel width).

Item 25.

CHECKLIST: MINIMUM STANDARDS FOR ACCEPTANCE OF AQUATIC RESOURCES DELINEATION REPORTS, LOS ANGELES DISTRICT REGULATORY DIVISION, USACE, MARCH 16, 2017 2 Section 1.1 and 2;
Table 1
FIELD CONDITIONS: A description of existing field conditions, including current land use, normal conditions, flood/drought conditions, irrigation practices, past or recent manipulation to the site, and characteristics considered atypical (for criteria see OHWM and wetland supplement guides). Include WETS tables or pre-site visit precipitation data as appropriate:
https://www.wcc.nrcs.usda.gov/climate/wets_doc.html.

Section 3.3
HYDROLOGY: A discussion of the hydrology at the site, including all known surface or subsurface sources, drainage gradients, downstream connections to the nearest traditional navigable waterway or interstate water, and any influence from manmade water sources such as irrigation.

N/A
REMOTE SENSING: If remote sensing was used in the delineation, provide an explanation of how it was used and include the name, date and source of the tools and data used and copies of the maps/photographs.

Section 3.4;
Figure 4; Appendix H
SOILS: Soil descriptions, soil map(s), soil photos, and a discussion of hydric soils (for wetland delineations only).

Figure 2
USGS QUADRANGLE: A site location map on a 7.5-minute USGS quadrangle. The map must provide the name of the USGS quadrangle, Section, Township, Range, and the latitude and longitude in decimal degree format.

Appendix L BULK UPLOAD FORM: For sites with 3 or more separate aquatic features a completed copy of the ORM Bulk Upload Aquatic Resources or Consolidated Excel spreadsheet must be submitted.

Figure 5
FIGURES: Map(s) of all delineated aquatic resources in accordance with the Final Map and Drawing Standards for the South Pacific Division Regulatory Program, available at:
http://www.spd.usace.army.mil/Missions/Regulatory/Public-Notices-andReferences/Article/651327/updated-map-and-drawing-standards/ Figure 7 and Appendix
H
SITE PHOTOGRAPHS: Ground photographs showing representative aquatic resource sites (or lack of), as well as an accompanying map of photo-points and table of photographic information (see Final Map and Drawing Standards for the South Pacific Division Regulatory Program item no. 8 a-c).

Appendix E
DATA FORMS: Completed data forms including all essential information to make a jurisdictional determination [e.g. 2006 Wetland Determination Data Form -- Arid West Supplement; 2010 Arid West Ephemeral and Intermittent Streams OHWM Datasheet].

Section 2
METHODS: A description of the methods used to survey the aquatic resource boundaries. If GPS data is used, the level of accuracy must be included. Ideally, the GPS equipment should have the capability of sub-meter (<=1 meter) level horizontal accuracy.

Appendix K
GIS DATA: Digital data for the site, aquatic resource boundaries, and data point locations must be provided in a geographic information system (GIS) format, preferably either ESRI shapefiles or Geodatabase format, but GoogleEarth KMZ or KML files may be acceptable non-complex projects. Each GIS data file must be accompanied by a metadata file containing the appropriate geographic coordinate system, projection, datum, and labeling description. If GIS data is unavailable or otherwise cannot be produced and the Corps determines a site visit is necessary, the aquatic resource boundaries should be physically marked with numbered flags or stakes to facilitate verification by the Corps.
