BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
SECTION 1.0 - INTRODUCTION
Jennings Environmental, LLC (Jennings) was retained by Tom Dodson & Associates to conduct a literature review and reconnaissance -level survey for the proposed Serrano Estates Development on APNs 0320- 161-08, 09, & 28 (Project) in the city of Yucaipa, San Bernardino County, California. The survey identified vegetation communities, the potential for the occurrence of special status species, or habitats that could support special status wildlife species, and recorded all plants and animals observed or detected within the Project boundary. This biological resources assessment is designed to address the potential effects of the proposed project on designated critical habitats and/or any species currently listed or formally proposed for listing as endangered or threatened under the federal Endangered Species Act (ESA) and the California Endangered Species Act (CESA) or species designated as sensitive by the California Department of Fish and Wildlife (CDFW) or the California Native Plant Society (CNPS). Information contained in this document is in accordance with accepted scientific and technical standards that are consistent with the requirements of the United States Fish and Wildlife Service (USFWS) and (CDFW). Additionally, the site was surveyed for any drainage features that would meet the definition of the Waters of the US (WOUS), Waters of the State (WOS), or CDFW jurisdiction.

1.1 PROJECT LOCATION
The project is generally located on the western edge of Section 19, Township 1 South, Range 1 West, and is depicted on the Yucaipa U.S. Geological Survey's (USGS) 7.5-minute topographic map. More specifically the project is located within Assessor Parcel Numbers (APNs) 0320-161-08, 09, & 28, within the city of Yucaipa, San Bernardino County, California. The Project site is located on the northeast corner of the intersection of Crystal St. and Yucaipa Ridge Rd. The site is surrounded by vacant land to the east, residential parcels to the south and west, and vacant land and a vineyard to the north (Figures 1 and 2 in Appendix A).

1.2 PROJECT DESCRIPTION
The Developer is proposing to subdivide a portion of the 52.02 acres into 51 residential lots. The residential lots will range from 12,787 square feet to 23,759 square feet. Additional improvements include the necessary infrastructure to provide utilities to each residence, including, sewer lines, electrical lines, water lines, and communication lines. The Project also proposes the installation of two water quality basins and a multi -purpose trail surrounding the development. Figure 3 in Appendix A overlays the site plan onto a current aerial map.

2.0 — METHODOLOGY

2.1 LITERATURE REVIEW
Prior to performing the field survey, existing documentation relevant to the Project site was reviewed.

The most recent records were reviewed for the following quadrangle containing and surrounding the Project site: Yucaipa and Forest Falls, USGS 7.5-minute quadrangles. The Forest Falls quad was included in this search due to the site's proximity to its border. These databases contain records of reported occurrences of federal- or state -listed endangered or threatened species, California Species of Concern Jennings Environmental P a g e 14

(SSC), or otherwise special status species or habitats that may occur within or in the immediate vicinity of the Project site. These sources include:
• California Natural Diversity Database (CNDDB) managed by CDFW (CDFW 2021) • USFWS Critical Habitat Mapper (USFWS 2022)
• California Native Plant Society's Electronic Inventory (CNPSEI) of Rare and Endangered Vascular Plants of California (CNPS 2022)
• U.S. Fish and Wildlife (USFWS) threatened and endangered species occurrence GIS overlay; • USDA Natural Resources Conservation Service (NRCS) Web Soil Survey; • USGS National Map;
• Calwater Watershed Maps
• USFWS Designated Critical Habitat Maps
• City of Yucaipa Development Code (Chapter 5 — Oak Tree Conservation)

2.2 SOILS
Before conducting the surveys, soil maps for San Bernardino County were referenced online to determine the types of soil found within the Project site. Soils were determined in accordance with categories set forth by the United States Department of Agriculture (USDA) Soil Conservation Service and by referencing the USDA Natural Resources Conservation Service (NRCS) Web Soil Survey (USDA 2022).

2.3 BIOLOGICAL RECONNAISSANCE -LEVEL SURVEY
Jennings biologist, Gene Jennings, conducted the general reconnaissance survey within the Project site to identify the potential for the occurrence of special status species, vegetation communities, or habitats that could support special status wildlife species. The surveys were conducted on foot, throughout the Project site between 1000 and 1145 hours on June 4, 2022. Weather conditions during the survey included temperatures ranging from 65.5 to 70.6 degrees Fahrenheit, with clear skies, no precipitation, and 2.2 to

7.4 mile per hour winds. Photographs of the Project site were taken to document existing conditions (Appendix B).

2.4 JURISDICTIONAL FEATURES
A general assessment of jurisdictional waters regulated by the United States Army Corps of Engineers (USACE), Regional Water Quality Control Board (RWQCB), and CDFW was conducted for the proposed Project area. Pursuant to Section 404 of the Clean Water Act, USACE regulates the discharge of dredged and/or fill material into waters of the United States. The State of California (State) regulates the discharge of material into waters of the State pursuant to Section 401 of the Clean Water Act and the California Porter- Cologne Water Quality Control Act (California Water Code, Division 7, §13000 et seq.). Pursuant to Division 2, Chapter 6, Sections 1600-1602 of the California Fish and Game Code, CDFW regulates all diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake, which supports fish or wildlife and its' associated riparian vegetation. The assessment was conducted by a desktop survey through the USGS National Hydrography Dataset for hydrological connectivity.

Additional discussion of the regulatory framework is provided in Appendix C.

2.5 VEGETATION
All plant species observed within the Project site were recorded. Vegetation communities within the Project site were identified and qualitatively described. Plant communities were determined in accordance with the Manual of California Vegetation, Second Edition (Sawyer et al. 2009). Plant nomenclature follows that of The Jepson Manual, Second Edition (Baldwin et al. 2012). A comprehensive list of the plant species observed during the survey is provided in Appendix D.

2.6 WILDLIFE
All wildlife and wildlife signs observed and detected, including tracks, scat, carcasses, burrows, excavations, and vocalizations, were recorded. Additional survey time was spent in those habitats most likely to be utilized by wildlife (native vegetation, wildlife trails, etc.) or in habitats with the potential to support state- and/or federally listed or otherwise special status species. Notes were made on the general habitat types, species observed, and the conditions of the Project site. A comprehensive list of the wildlife species observed during the survey is provided in Appendix D.

2.7 WILDLIFE CORRIDORS AND HABITAT CONSERVATION PLAN
According to the California Essential Habitat Connectivity Project, the Project site is not mapped within an area for wildlife movement. Additionally, the Project site is not within an adopted habitat conservation plan. Therefore, the proposed Project will not have an impact on any current wildlife corridors or habitat conservation plans.

2.8 CITY OF YUCAIPA DEVELOPMENT CODE (CHAPTER 5 — OAK TREE CONSERVATION) The City of Yucaipa has a section of the development code that specifically addresses the protection of oak trees within the City. The development code was searched prior to the site visit and it states:

Further uncontrolled and indiscriminate destruction of oak trees would detrimentally affect the safety and welfare of the citizens of Yucaipa. The conservation program outlined in this chapter contributes to the welfare and aesthetics of the community and retains the great historical and environmental value of these trees. This chapter sets forth the policy of the City to require the conservation of all healthy oak trees unless reasonable and conforming use of the property justifies the removal, cutting, pruning and/or encroachment into the protected zone of an oak tree.

Any person who owns, controls, has custody or possession of any real property within the City that is improved or has been approved for development, or which is part of or associated with the City approved development of another piece of property, such as any parcel to be maintained as permanent open space or for recreational purposes, shall maintain all oak tree(s) located thereon in a state of good health pursuant to the Oak Tree Conservation and Protection Guidelines adopted by City Council resolution. Failure to do so will constitute a violation of this article.

SECTION 3.0 — RESULTS

3.1 LITERATURE REVIEW RESULTS
According to the CNDDB, CNPSEI, and other relevant literature and databases, 51 sensitive species, 9 of which are listed as threatened or endangered, and 8 sensitive habitats have been documented in the Yucaipa and Forest Falls quads. This list of sensitive species and habitats includes any State and/or federally listed threatened or endangered species, CDFW designated Species of Special Concern (SSC), and otherwise Special Animals. "Special Animals" is a general term that refers to all of the taxa the CNDDB is interested in tracking, regardless of their legal or protection status. This list is also referred to as the list of "species at risk" or "special status species." The CDFW considers the taxa on this list to be those of greatest conservation need.

An analysis of the likelihood for the occurrence of all CNDDB sensitive species documented in the Yucaipa and Forest Falls quads is provided in Table 2, in Appendix D. This analysis takes into account 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. According to the databases, no sensitive habitat, including USFWS designated critical habitat, occurs within or adjacent to the project site.

3.1.1 SOILS
After a review of the USDA Soil Conservation Service and by referencing the USDA NRCS Web Soil Survey (USDA 2022), it was determined that the Project site is located within the San Bernardino County Southwestern Area (California area CA677). Based on the results of the database search, one (1) soil type is documented in the area:

Soboba stony loamy sand, 2 to 9 percent slopes (SpC). This soil is excessively drained with a high to very high capacity to transmit water. This soil consists of alluvium derived from granite, typically ranges in elevation from 960 to 3,690 feet above mean sea level (amsl) and is not considered prime farmland.

3.1.2 SPECIAL STATUS SPECIES BACKGROUND
Of the 51 species found within the Yucaipa and Forest Falls quads, 24 have a special designation of either:
federally listed, state listed, or a species of special concern (SSC) under the California Fish and Game Code.

However, the Project site is either outside the known range for the species or suitable habitat does not occur within the Project area. Therefore, no further discussion or recommendations are required for the following species:
— Southern California legless lizard
— California glossy snake
— Coastal whiptail
— Swainson's hawk
— Northwestern San Diego pocket mouse
— Southern rubber boa
— Black swift
— San Bernardino kangaroo rat

3.1.3 DESIGNATED CRITICAL HABITAT
The site is not located within or adjacent to any USFWS designated Critical Habitat. No further action is required.

3.1.4 JURISDICTIONAL WATERS
Aerial imagery of the site was examined and compared with the surrounding USGS 7.5-minute topographic quadrangle maps to identify drainage features within the survey area as indicated from topographic changes, blue -line features, or visible drainage patterns. The U.S. Fish and Wildlife Service National Wetland Inventory and Environmental Protection Agency (EPA) Water Program "My Waters" data layers were also reviewed to determine whether any hydrologic features and wetland areas had been documented within the vicinity of the site. Similarly, the Soil maps from the U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) Web Soil Survey (USDA 2022) were reviewed to identify the soil series on -site and to check if they have been identified regionally as hydric soils. Upstream and downstream connectivity of waterways (if present) was reviewed in the field, on aerial imagery, and topographic maps to determine jurisdictional status. After review of the aerials, it appeared that there was a jurisdictional feature on the western edge of the parcel.

3.1.5 HYDROLOGY AND HYDROLOGIC CONNECTIVITY
Hydrologically, the project site is located within the Crafton Hydrologic Sub -Area (HSA 801.56), as identified on the Calwater Watershed maps. This Crafton HSA area comprises a 2,697-acre drainage area within the larger Upper Santa Ana River Watershed Area (Hydrologic Unit Code [HUC10] 1807020305, US Watershed Maps) (CalTrans, 2022). The Upper Santa Ana River watershed in the Yucaipa area is bordered to the north by the Lytle Creek, West Fork Mojave River, Deep Cree, Bear Creek, and Headwaters Santa Ana River watersheds, to the east by the Headwaters Whitewater River watershed, to the south by the San Timoteo Wash watershed, and to the west by Middle Santa Ana River watershed. (Figure 4 in Appendix A).

All tree fellers, tree surgeons, or anyone using explosives within the City limits in connection with the cutting down or removal of any oak tree shall first apply to the City Manager for a permit to do so and shall furnish such bond or insurance as the City Manager shall deem necessary for the protection of the property owner or any other person from any possible damage as a result of such work.

3.2 FIELD STUDY RESULTS

3.2.1 VEGETATION
The vegetation on -site consists of a mixture of Eriogonum fosciculatum Shrubland Alliance (California buckwheat scrub), Amsinckia (menziesii, tessellata) - Phacelia spp. Herbaceous Alliance (Fiddleneck — Phacelia Fields), Brossica nigra - Centourea (solstitialis, melitensis) Herbaceous Semi -Natural Alliance (Upland mustards or star -thistle fields), and ruderal/disturbed vegetation. {Figure 5 in Appendix Al. The site is relatively undisturbed with the exception of a portion of the site, on the western edge, that is maintained for weed abatement. The site also contains a few dirt roads that transverse the property from west to east and north to south. A complete list of all plants observed is provided in Table 1 of Appendix D and Figure 5 in Appendix A details the vegetation found on -site.

3.2.2 WILDLIFE
Multiple birds and two mammals were seen or heard during the survey. Species observed or otherwise detected on or in the vicinity of the project site during the surveys included; house finch (Hoemorhous Jennings Environmental P a g e 19

mexicanus) and California ground squirrel (Otospermophilus beecheyi). A complete list of all species observed is provided in Table 1 of Appendix D.

The project site is located within a partially developed area of Yucaipa. Portions of the site showed signs of past mowing activities and foot traffic was also evident. There is no habitat within the proposed project footprint, as well as the immediate surrounding area, that is suitable for the sensitive species identified in the CNDDB search (Table 2 in Appendix D).

3.2.3 SPECIAL STATUS SPECIES
No State and/or federally listed threatened or endangered species or other sensitive species were observed on -site during surveys.

3.2.4 NESTING BIRDS
The Project site and immediate surrounding area do contain habitat suitable for nesting birds. As such the Project is subject to the following nesting bird regulations. Recommendations for avoidance and minimization are in section 4.

Miaratory Bird Treaty Act
The Migratory Bird Treaty Act of 1918. This Act implements four international conservation treaties that the U.S. entered into with Canada in 1916, Mexico in 1936, Japan in 1972, and Russia in 1976. It is intended to ensure the sustainability of populations of all protected migratory bird species. The Act has been amended with the signing of each treaty, as well as when any of the treaties were amended, such as with Mexico in 1976 and Canada in 1995. The Act prohibits the take (including killing, capturing, selling, trading, and transport) of protected migratory bird species without prior authorization by the Department of Interior U.S. Fish and Wildlife Service.

California Fish and Game Code
The Project site is also subject to Sections 3503 and 3503.5 of the Fish and Game Code. Section 3503 states, "It is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this code or any regulation made pursuant thereto". And Section 3503.5 states, "It is unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds -of - prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant thereto".

3.2.4 JURISDICTIONAL WATERS
Waters of the United States and Waters of the State
The USACE has the authority to permit the discharge of dredged or fill material in Waters of the U.S. (WOUS) under Section 404 CWA. While the Regional Water Quality Board has authority overthe discharge of dredged or fill material in Waters of the State under Section 401 CWA as well as the Porter -Cologne Water Quality Control Act. The Project area was surveyed with 100 percent visual coverage and no drainage features were present on site that met the definition for WOUS. As such, the subject parcel does not contain any wetlands, Waters of the U.S., or Waters of the State.

Fish and Game Code Section 1602 - State Lake and/or Streambed The CDFW asserts jurisdiction over any drainage feature that contains a definable bed and bank or associated riparian vegetation. The Project area was surveyed with 100 percent visual coverage and the Project Site does contain a drainage feature that is considered jurisdictional. Table 1 below describes the limits of CDFW jurisdiction within the Project site.

Although Drainage A is jurisdictional under the Fish and Game Code, the project has been designed to avoid this area. Figure 6 in Appendix A shows the site plan in relation to the jurisdictional feature.

3.2.5 CITY OF YUCAIPA DEVELOPMENT CODE (CHAPTER 5 — OAK TREE CONSERVATION) The site does not contain any oak trees as described in Section 89.0505 of the City's Development Code as detailed above. Therefore, the proposed Project does not have any impacts on any oak trees. No further studies or surveys are recommended.

Section 4.0 - CONCLUSIONS AND RECOMMENDATIONS
Based on the literature review and personal observations made in the immediate vicinity, no State and/or federally listed threatened or endangered species are documented/or expected to occur within the Project site. Additionally, no plant species with the California Rare Plant Rank (CRPR) of 1 or 2 were observed on -site or documented to occur on -site in the relevant databases. No other sensitive species were observed within the project area or buffer area.

Jurisdictional Features
The Project Site does contain a jurisdictional feature, Drainage A. However, the Proposed Project does not include any modifications or alterations to this drainage. As such the Project will not need to obtain a 404 permit from the US Army Corps of Engineers, a 401 Water Quality Certification from the Santa Ana Regional Water Quality Board, or a 1602 Agreement from the California Department of Fish and Wildlife.

Should the scope of the Project change and modifications or alterations to Drainage A become necessary, the District will need to obtain the necessary approvals from CDFW prior to disturbing the drainage.

Nesting Birds
Since there is some habitat within the project site and adjacent area that is suitable for nesting birds in general, the following mitigation measure should be implemented.

Nesting bird nesting season generally extends from February 1 through September 15 in southern California and specifically, March 15 through August 31 for migratory passerine birds. To avoid impacts to nesting birds (common and special status) during the nesting Jennings Environmental P a g e 1 11

BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
season, a qualified Avian Biologist will conduct pre -construction Nesting Bird Surveys (NBS) prior to project -related disturbance to nestable vegetation to identify any active nests. If no active nests are found, no further action will be required. If an active nest is found, the biologist will set appropriate no -work buffers around the nest which will be based upon the nesting species, its sensitivity to disturbance, nesting stage, and expected types, intensity, and duration of the disturbance. The nests and buffer zones shall be field -checked weekly by a qualified biological monitor. The approved no -work buffer zone shall be clearly marked in the field, within which no disturbance activity shall commence until the qualified biologist has determined the young birds have successfully fledged and the nest is inactive.

City of Yucaipa Development Code (Chapter 5 — Oak Tree Conservation) The Project site does not contain any of the species that are covered under the Development Code.

Therefore, the Project is consistent with Chapter 5 of the City of Yucaipa's Development Code.

BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT

1.1 FEDERAL JURISDICTION

1.1.1 United States Army Corps of Engineers
Activities within inland streams, wetlands, and riparian areas in California are regulated by agencies at the federal, state, and regional levels. At the federal level, the U.S. Army Corps of Engineers (USACE) Regulatory Program regulates activities within wetlands and waters of the US pursuant to Section 404 of the Federal Clean Water Act (CWA).

At the state level, the California Department of Fish and Wildlife (CDFW) regulates activities within the bed, bank, and associated habitat of a stream under the Fish and Game Code §§ 1600- 1616. The California State Water Resources Board (SWRB) delegates authority at the regional level to Regional Water Quality Control Boards (RWQCB) that are responsible for regulating discharge into waters of the US under Section 401 of the federal CWA and waters of the State under the California Porter -Cologne Water Quality Act.

The CWA was implemented to maintain and restore the chemical, physical, and biological integrity of the Waters of the United States (33 Code of Federal Regulations [CFR] Part 328 Section 328.3). "Waters of the US" are defined as follows:
(a) Jurisdictional waters. For purposes of the Clean Water Act, 33 U.S.C. 1251 et seq. and its implementing regulations, subject to the exclusions in paragraph (b) of this section, the term "waters of the United States" means:
(1) The territorial seas, and waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including waters which are subject to the ebb and flow of the tide; (2) Tributaries;
(3) Lakes and ponds, and impoundments of jurisdictional waters; and (4) Adjacent wetlands.
(b) Non jurisdictional waters. The following are not "waters of the United States":
(1) Waters or water features that are not identified in paragraph (a)(1), (2), (3), or (4) of this section;
(2) Groundwater, including groundwater drained through subsurface drainage systems;
(3) Ephemeral features, including ephemeral streams, swales, gullies, rills, and pools;
(4) Diffuse stormwater run-off and directional sheet flow over upland; (5) Ditches that are not waters identified in paragraph (a)(1) or (2) of this section, and those portions of ditches constructed in waters identified in paragraph (a)(4) of this section that do not satisfy the conditions of paragraph (c)(1) of this section; (6) Prior converted cropland;
(7) Artificially irrigated areas, including fields flooded for agricultural production, that would revert to upland should application of irrigation water to that area cease;Artificial lakes and ponds, including water storage reservoirs and farm, irrigation, stock watering, and log cleaning ponds, constructed or excavated in upland or in nonjurisdictional waters, so long as those artificial lakes and ponds Jennings Environmental P a g e 129

BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
are not impoundments of jurisdictional waters that meet the conditions of paragraph (c)(6) of this section;
(8) Water -filled depressions constructed or excavated in upland or in non - jurisdictional waters incidental to mining or construction activity, and pits excavated in upland or in nonjurisdictional waters for the purpose of obtaining fill, sand, or gravel;
(9) Stormwater control features constructed or excavated in upland or in non - jurisdictional waters to convey, treat, infiltrate, or store stormwater runoff; (10) Groundwater recharge, water reuse, and wastewater recycling structures, including detention, retention, and infiltration basins and ponds, constructed or excavated in upland or in non -jurisdictional waters; and (11) Waste treatment systems.
(c) Definitions. In this section, the following definitions apply:
(1) Adjacent wetlands. The term adjacent wetlands means wetlands that:
(i) Abut, meaning to touch at least at one point or side of, a water identified in paragraph (a)(1), (2), or (3) of this section; (ii) Are inundated by flooding from a water identified in paragraph (a)(1), (2), or (3) of this section in a typical year;
(iii) Are physically separated from a water identified in paragraph (a)(1), (2), or (3) of this section only by a natural berm, bank, dune, or similar natural feature; or
(iv) Are physically separated from a water identified in paragraph (a)(1), (2), or (3) of this section only by an artificial dike, barrier, or similar artificial structure so long as that structure allows for a direct hydrologic surface connection between the wetlands and the water identified in paragraph (a)(1), (2), or (3) of this section in a typical year, such as through a culvert, flood or tide gate, pump, or similar artificial feature. An adjacent wetland is jurisdictional in its entirety when a road or similar artificial structure divides the wetland, as long as the structure allows for a direct hydrologic surface connection through or over that structure in a typical year. (2) Ditch. The term ditch means a constructed or excavated channel used to convey water.
(3) Ephemeral. The term ephemeral means surface water flowing or pooling only in direct response to precipitation (e.g., rain or snow fall). (4) High tide line. The term high tide line means the line of intersection of the land with the water's surface at the maximum height reached by a rising tide. The high tide line may be determined, in the absence of actual data, by a line of oil or scum along shore objects, a more or less continuous deposit of fine shell or debris on the foreshore or berm, other physical markings or characteristics, vegetation lines, tidal gages, or other suitable means that delineate the general height reached by a rising tide. The line encompasses spring high tides and other high tides that occur with periodic frequency but does not include storm surges in which there is a departure from the normal or predicted reach of the tide due to the piling up of Jennings Environmental P a g e 130

Page 609 ends

BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
water against a coast by strong winds, such as those accompanying a hurricane or other intense storm.
(5) Intermittent. The term intermittent means surface water flowing continuously during certain times of the year and more than in direct response to precipitation (e.g., seasonally when the groundwater table is elevated or when snowpack melts).
(6) Lakes and ponds, and impoundments of jurisdictional waters. The term lakes and ponds, and impoundments of jurisdictional waters means standing bodies of open water that contribute surface water flow to a water identified in paragraph (a)(1) of this section in a typical year either directly or through one or more waters identified in paragraph (a)(2), (3), or (4) of this section. A lake, pond, or impoundment of a jurisdictional water does not lose its jurisdictional status if it contributes surface water flow to a downstream jurisdictional water in a typical year through a channelized non -jurisdictional surface water feature, through a culvert, dike, spillway, or similar artificial feature, or through a debris pile, boulder field, or similar natural feature. A lake or pond, or impoundment of a jurisdictional water Start Printed Page 22339is also jurisdictional if it is inundated by flooding from a water identified in paragraph (a)(1), (2), or (3) of this section in a typical year.
(7) Ordinary high watermark. The term ordinary high watermark means 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 soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.
(8) Perennial. The term perennial means surface water flowing continuously year- round.
(9) Prior converted cropland. The term prior converted cropland means any area that, prior to December 23, 1985, was drained or otherwise manipulated for the purpose, or having the effect, of making production of an agricultural product possible. EPA and the Corps will recognize designations of prior converted cropland made by the Secretary of Agriculture. An area is no longer considered prior converted cropland for purposes of the Clean Water Act when the area is abandoned and has reverted to wetlands, as defined in paragraph (c)(16) of this section. Abandonment occurs when prior converted cropland is not used for, or in support of, agricultural purposes at least once in the immediately preceding five years. For the purposes of the Clean Water Act, the EPA Administrator shall have the final authority to determine whether prior converted cropland has been abandoned.
(10) Snowpack. The term snowpack means layers of snow that accumulate over extended periods of time in certain geographic regions or at high elevation (e.g., in northern climes or mountainous regions).
(11) Tidal waters and waters subject to the ebb and flow of the tide. The terms tidal waters and waters subject to the ebb and flow of the tide mean those Jennings Environmental P a g e 131

Page 610 ends

BIOLOGICAL RESOURCES ASSESSMENT AND JURISDICTIONAL DELINEATION

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
waters that rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun. Tidal waters and waters subject to the ebb and flow of the tide end where the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by hydrologic, wind, or other effects.
(12) Tributary. The term tributary means a river, stream, or similar naturally occurring surface water channel that contributes surface water flow to a water identified in paragraph (a)(1) of this section in a typical year either directly or through one or more waters identified in paragraph (a)(2), (3), or (4) of this section. A tributary must be perennial or intermittent in a typical year. The alteration or relocation of a tributary does not modify its jurisdictional status as long as it continues to satisfy the flow conditions of this definition. A tributary does not lose its jurisdictional status if it contributes surface water flow to a downstream jurisdictional water in a typical year through a channelized non - jurisdictional surface water feature, through a subterranean river, through a culvert, dam, tunnel, or similar artificial feature, or through a debris pile, boulder field, or similar natural feature. The term tributary includes a ditch that either relocates a tributary, is constructed in a tributary, or is constructed in an adjacent wetland as long as the ditch satisfies the flow conditions of this definition. (13) Typical year. The term typical year means when precipitation and other climatic variables are within the normal periodic range (e.g., seasonally, annually) for the geographic area of the applicable aquatic resource based on a rolling thirty- year period.
(14) Upland. The term upland means any land area that under normal circumstances does not satisfy all three wetland factors (i.e., hydrology, hydrophytic vegetation, hydric soils) identified in paragraph (c)(16) of this section, and does not lie below the ordinary high water mark or the high tide line of a jurisdictional water.
(15) Waste treatment system. The term waste treatment system includes all components, including lagoons and treatment ponds (such as settling or cooling ponds), designed to either convey or retain, concentrate, settle, reduce, or remove pollutants, either actively or passively, from wastewater prior to discharge (or eliminating any such discharge).
(16) Wetlands. The term wetlands means areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.

Section 404 (b)(1) compliance must be demonstrated before a Section 404 permit can be issued. Guidelines for a Section 404(b)(1) analysis were developed by the EPA in conjunction with USACE (40 CFR Parts 230). The guidelines allow the discharge of dredged or fill material into the aquatic system only if there is no practicable alternative that would have less adverse impacts.

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT

1.2 STATE JURISDICTION
The State of California (State) regulates discharge of material into waters of the State pursuant to Section 401 of the CWA as well as the California Porter -Cologne Water Quality Control Act (Porter -Cologne; California Water Code, Division 7, §13000 et seq.). Waters of the State are defined by Porter -Cologne as "any surface water or groundwater, including saline waters, within the boundaries of the state" (Water Code Section 13050(e)). Waters of the State broadly includes all waters within the State's boundaries (public or private), including waters in both natural and artificial channels.

1.2.1 Regional Water Quality Control Board
Under Porter -Cologne, the State Water Resources Control Board (SWRCB) and the local Regional Water Quality Control Boards (RWQCB) regulate the discharge of waste into waters of the State.

Discharges of waste include "fill, any material resulting from human activity, or any other 'discharge' that may directly or indirectly impact 'waters of the state."' Porter -Cologne reserves the right for the State to regulate activities that could affect the quantity and/or quality of surface and/or groundwaters, including isolated wetlands, within the State. Wetlands were defined as waters of the State if they demonstrated both wetland hydrology and hydric soils. Waters of the State determined to be jurisdictional for these purposes require, if impacted, waste discharge requirements (WDRs).

When an activity results in fill or discharge directly below the OHWM of jurisdictional waters of the United States (federal jurisdiction), including wetlands, a CWA Section 401 Water Quality Certification is required. If a proposed project is not subject to CWA Section 401 certification but involves activities that may result in a discharge to waters of the State, the project may still be regulated under Porter -Cologne and may be subject to waste discharge requirements. In cases where waters apply to both CWA and Porter -Cologne, RWQCB may consolidate permitting requirements to one permit.

1.2.2 California Department of Fish and Wildlife
Pursuant to Division 2, Chapter 6, Sections 1600-1602 of the California Fish and Game Code, the California Department of Fish and Wildlife (CDFW) regulates all diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake, which supports fish or wildlife.

CDFW defines a "stream" (including creeks and rivers) as "a body of water that flows at least periodically or intermittently through a bed or channel having banks and supports fish or other aquatic life. This includes watercourses having surface or subsurface flow that supports or has supported riparian vegetation" (California Code of Regulations, Title 14, Section 1.72). The jurisdiction of CDFW may include areas in or near intermittent streams, ephemeral streams, rivers, creeks, dry washes, sloughs, blue -line streams that are indicated on USGS maps, watercourses that may contain subsurface flows, or within the flood plain of a water body.

FOR THE PROPOSED SERRANO ESTATES DEVELOPMENT PROJECT
CDFW's definition of "lake" includes "natural lakes or man-made reservoirs." CDFW limits of jurisdiction typically include the maximum extents of the uppermost bank -to -bank distance and/or the outermost extent of riparian vegetation dripline, whichever measurement is greater.

In a CDFW guidance of stream processes and forms in dryland watersheds (Vyverberg 2010), streams are identified as having one or more channels that may all be active or receive water only during some high flow event. Subordinate features, such as low flow channels, active channels, banks associated with secondary channels, floodplains, and stream -associated vegetation, may occur within the bounds of a single, larger channel. The water course is defined by the topography or elevations of land that confine a stream to a definite course when its waters rise to their highest level. A watercourse is defined as a stream with boundaries defined by the maximal extent or expression on the landscape even though flow may otherwise be intermittent or ephemeral.

Artificial waterways such as ditches (including roadside ditches), canals, aqueducts, irrigation ditches, and other artificially created water conveyance systems also may be under the jurisdiction of CDFW. CDFW may claim jurisdiction over these features based on the presence of habitat characteristics suitable to support aquatic life, riparian vegetation, and/or stream - dependent terrestrial wildlife. As with natural waterways, the limit of CDFW jurisdiction of artificial waterways includes the uppermost bank -to -bank distance and/or the outermost extent of riparian vegetation dripline, whichever measurement is greater.

CDFW does not have jurisdiction over wetlands but has jurisdiction to protect against a net loss of wetlands. CDFW supports the wetland criteria recognized by USFWS; one or more indicators of wetland conditions must exist for wetlands conditions to be considered present. The following is the USFWS accepted definition of a wetland:

Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. For purposes of this classification, wetlands must have one or more of the following three attributes:
(1) at least periodically, the lands supports hydrophytes, (2) the substrate is predominantly undrained hydric soil; and (3) the substrate is nonsoil and is saturated withwater or covered by shallow water at some time during the growing season of each year (Cowardin et al. 1979).

In A Clarification of the U.S. Fish and Wildlife Service's Wetland Definition (Tiner 1989), the USFWS definition was further clarified "that in order for any area to be classified as wetland by the Service, the area must be periodically saturated or covered by shallow water, whether wetland vegetation and/or hydric soils are present or not; this hydrologic requirement is addressed in the first sentence of the definition." When considering whether an action would result in a net loss of wetlands, CDFW will extend jurisdiction to USFWS-defined wetland conditions where such conditions exist within the riparian vegetation that is associated with a stream or lake and does not depend on whether those features meet the three -parameter USACE methodology of wetland determination. If impacts to wetlands under the jurisdiction of CDFW Jennings Environmental P a g e 134

are unavoidable, a mitigation plan will be implemented in coordination with CDFW to support the CDFW policy of "no net loss" of wetland habitat.

Coding and Terms
E = Endangered T = Threatened C = Candidate FP = Fully Protected WL = Watch List SSC = Species of Special Concern R = Rare State Species of Special Concern: An administrative designation given to vertebrate species that appear to be vulnerable to extinction because of declining populations, limited acreages, and/or continuing threats. Raptor and owls are protected under section 3502.5 of the California Fish and Game code: "It is unlawful to take, possess or destroy any birds in the orders Falconiformes or Strigiformes or to take, possess or destroy the nest or eggs of any such bird."
State Fully Protected: The classification of Fully Protected was the State's initial effort in the 1960's to identify and provide additional protection to those animals that were rare or faced possible extinction. Lists were created for fish, mammals, amphibians and reptiles. Fully Protected species may not be taken or possessed at any time and no licenses or permits may be issued for their take except for collecting these species for necessary scientific research and relocation of the bird species for the protection of livestock.

Global Rankings (Species or Natural Community Level):

GI = Critically Imperiled — At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors.

G2 = Imperiled — At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors.

G3 = Vulnerable — At moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors.

G4 = Apparently Secure — Uncommon but not rare; some cause for long-term concern due to declines or other factors.

G5 = Secure — Common; widespread and abundant.
? = Uncertainty in the exact status of an element (could move up or down one direction from current rank) Subspecies Level: Taxa which are subspecies or varieties receive a taxon rank (T-rank) attached to their G-rank. Where the G-rank reflects the condition of the entire species, the T-rank reflects the global situation of just the subspecies. For example: the Point Reyes mountain beaver, Aplodontia rufa ssp. phaea is ranked G512. The G-rank refers to the whole species range i.e., Aplodontia rufa. The T-rank refers only to the global condition of ssp. phaea.

State Ranking:

S I = Critically Imperiled — Critically imperiled in the State because of extreme rarity (often 5 or fewer populations) or because of factor(s) such as very steep declines making it especially vulnerable to extirpation from the State.

S2 = Imperiled — Imperiled in the State because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the State.

S3 = Vulnerable — Vulnerable in the State due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation from the State.

S4 = Apparently Secure — Uncommon but not rare in the State; some cause for long-term concern due to declines or other factors.

S5 = Secure — Common, widespread, and abundant in the State.

California Rare Plant Rankings (CNPS List):

IA = Plants presumed extirpated in California and either rare or extinct elsewhere. lB = Plants rare, threatened, or endangered in California and elsewhere. 2A = Plants presumed extirpated in California, but common elsewhere. 213 = Plants rare, threatened, or endangered in California, but more common elsewhere. 3 = Plants about which more information is needed; a review list. 4 = Plants of limited distribution; a watch list.

Threat Ranks:
.1 = Seriously threatened in California (over 80% of occurrences threatened / high degree and immediacy of threat) .2 = Moderately threatened in California (20-80% occurrences threatened / moderate degree and immediacy of threat) .3 = Not very threatened in California (less than 20% of occurrences threatened / low degree and immediacy of threat or no current threats known) Jennings Environmental P a g e 157

Review and Comment: Phase I Cultural Resources Assessment of Tentative Tract 14297, 52.51 acres located just north of Ivy Street and immediately south of the San Bernardino National Forest boundary, Yucaipa, San Bernardion County (Pertinent to Tract 20375-Currently Processing).

Dear Mr. Kreidel:

I am writing to you with the results of our review of the Phase I Cultural Resources Assessment entitled: "A Cultural Assessment of a 52.51 Acre Tract of Land Designated as Tentative Tract 14297 Located Near the Community of Yucaipa, San Bernardino County, California" (1989 Swanson & de Munck). Mark Swanson and Victor de Munck, Ph.D. are experienced, professional archaeologists/anthropologists that are qualified to undertake cultural resource investigations. The methodology employed in the field investigation is sound and meets current standards. Their study, prepared in 1989 met all acceptable standards for Phase I Cultural Resources studies at that time.

After thoroughly reviewing their report, I concur with their findings and recommendations.

For the purpose of the current CEQA process, this information is reliable. However, it is recommended that prior to the onset of any future earth -disturbing activities in connection with the project, an updated report should be produced. This would include a new records search and Native American Scoping. I would not recommended a new field study unless the results of the new records search indicated that it was necessary.

I hope this brief letter is adequate for your current needs. Please do not hesitate to contact me if you have questions.

Very truly yours,

'-W;ACEMENT SU-1-2uk?Y
In March _939, Research Associates conducted a cultural resource assessment of Tentative Tract No. 14297, a 52.51 acre tract of land, located near the community of Yucaipa, San Bernardino County, California.

The obiective of this study was to locate, identify and evaluate cultural resources within the boundaries of the subject property. --his stuc:; included a records check conducted by the Archaeological Information Center ac the San Bernardino County Museum in Redlands, a review of the pertinent literature and an intensive field investigation of the subject property.

The field investigation was limited to potential surface findings.

Results of the field survey were negative and development is not expected to adversely impact on cultural resources. If subsurface cultural deposits are exposed during development, a qualified archaeologist should be con- sulted to evaluate these resources and to implement data recovery/?rotec- t ion measures.

INTRODUCTION
At the request of fir. Lydell Lambeth, Research Associates conducted a cultural resource assessment of a 52.51 acre tract of land designated as Tentative Tract No. 14297. The subject property is located approximately two miles north of downtown Yucaipa and is bounded by the San Bernardino

Page 640 ends

2 National Forest along its northernboundary. The southern border of the subject property is approximately 400 feet north of and parallel to Ivy Street, the western and eastern borders are approximately coterminous with to dirt roads. 19-hicz plastic stakes also mark portions of s_:'jer_t pro-perty boundaries. The property is situated in SW 1/4 and N;d 1/4 of the 7 1/4 of Section 19, Township 1S, Range 1W, SBM as shown on the CiSGS Yucaipa Calif. 7.5' series quadrangle (Figure 1).

The proposed development of the subject property involves a subdivision of the 52.51 acre tract of land into a residential tract containing 41 lots. Each lot will consist of a minimum of one acre.

The purpose of this study is to satisfy San Bernardino C6unty and federal regulations regarding cultural resource management of land proposed for development. Significance of resources was evaluated with reference to eligibility for nomination to the National Register o- Historic Places.

CULTURAL HISTORY
This section of the report is divided into a review of the prehistory and ethnohistory and recent history of the area as revealed in the pertinent literature.

Preiistory
Human populations have occupied Southern California for at least the last 12,000 years. The earliest sites (12,000-8,500 B.P.) have been designated as the Early Hunting Stage, characterized by fluted or Leaf -shaped projectile points, crescents, core tools, scrapers and

4 choDDers. The absence cf milling tools suZgests an orientation to hunting. The onset of the Early Millingstone Stage (8,500 to 5,000 E.P.) is marked by increases in plant exploitation and population size.

Typical artifact assemblages of this period consist of manos, metates, choppers and scraper planes. Projectile points are rare. Further population growth and adaptations to various ecological niches typify the Regional Specialization Stage (5,000-300 B.P.). In southern California, a heavy dependence on both hunting and gathering of wild plant foods continued into the historic period (Meighan 1978).

Ethnohistory
The area in which zl:e subject property is located was populated by the Serrano Indians at the time of contact. Other Indian groups such as the Cahuilla and Gabrielino may also have lived or used the area for resource procurement. 'These aboriginal Indian groups are part of the southern California branch of the Shoshonean language stock (Bean and Smith 1978).

The Serrano Indians were primarily hunters and gatherers and, like most aboriginal groups, settlement Locations were determined by t . availability and accessibility of water. The name "Serrano" comes from the Spanish term meaning "mountaineer" or "highlander." They lived in small villages that included individual and extended family dwellings as well as a ceremonial house where the lineage leader lived. The Serrano were organized into exogamous patrilineal clans, with village leadership determined by heredity and seniority within the dominant patriline (Gifford 1951). Settlements ranged in size from 10 to 20 dwellings, circular in shape and composed of a framework of poles and tules or brush

5 (Schuiling 1984). Trading and cooperative inter -clan networks were established through marriage.

Food sources depended on seasonal availability. The primary pant food sources were acorns, pine nuts, wild berries, cactus fruit, mesquite beans, and various bulbs, roots and grass seeds. Animals hunted were -leer, antelope, ducks, rabbits, quail, birds, rodents and insects.

History
At the time of contact, in the late 1700's, an estimated 1500 Serranos inhabited the San Bernardino Valley (Schuiling 1984). The Serrano settlements, called rancherlas by the Spanish, came under the influence of the San Gabriel *fission and its outlying auxiliary missions (asiscenc as) in the 1770's.

The Mission system was intended to "Christianize" and "civilize" aboriginal populations; it also developed into an extensive agricu' t,:.ra'_ and pastoral empire which relied on Indian labor.

Under Father Jose Maria Zalvidea, the San Gabriel Mission set uo pastoral and ranching outposts in the San Bernardino Valley. These outposts were typically located near t'ze Tndian rancherias from which they recruited their labor.

On May 10, 1810 Father Dumetz established a temporary chapel which he called San Bernardino, and so the valley was named. ':.ie location of the chapel is disputed, some argue that it was located along the Rialto Bench while others claim it was located near the Guachama Rancheria in Old San Bernardino along Cottonwood Sow (Robinson 1958:10; Schuiling 1984:26).

Page 644 ends

6 Rancho San Bernardino was established in 1819. It was possibly the most economically productive ranch in the California Mission system with land used primarily for cantle grazing, fruit orchards, and vineyards. In 1830, an estimated 25,000 cattle were on the ranch (Schuiling 1984:27).

The Mexican government implemented a secularization program in 1833 whic`1 abruptly put a halt to Mission economic activities. "fission lands were turned over to the government and then redistributed as land grants to Mexican citizens. This led to the economic disenfranchise-ment of ":fission Indians" who had become dependent on the missions for their livelihood. Many joined Indian groups who raided nearby ranches for livestock and goods; others stayed on and worked on land grant ranchos.

The Mexican Period extended from 1834 to 1848 and is alternatively referred to as the Rancho Period. Land grants were limited to 11 leagues per applicant (about 48,000 acres). The most important Spanish Dons were the Lugos, Sepulveda, Yorba, Bandini, Tapio, Palomares, Pico and Waite (or Blanco) families. Land grant boundaries were based on vague descriptions of trees, streams or other geographical landmarks.

The Yucaipa portion of Ranch San Bernardino did not include the study area. Yucaipa received its name from the Yucaipat rancherfe, located approximately three miles south of the study area. The rancheria was inhabited by Serranos as late as 1852. This village site was excavated in 1976 and has been formally recorded as Ca-SBr-1000. This site is documentd to have both a late prehistoric and ethnohi.storic component and an earlier ?tilling Stone Horizon component (Hicks 1958; Martz 1977).
