Geomorphic Setting
DRAFT NCCP/MSAA/HCP CHAPTER 3: EXISTING BIOLOGICAL AND HYDROLOGIC/ GEOMORPHIC SETTING This Chapter describes the biological setting of the approximately 131,600-acre Southern NCCP/MSAA/HCP study area, including portions of the CNF (Figure 3-M). Within the study area, the approximately 91,660 acres of non-federal land defines the planning area for the NCCP/MSAA/HCP. Management of resources in the CNF is the responsibility of the USFS. Therefore, the description of the biological and hydrologic/geomorphic setting includes a general description of the CNF, but the main focus of this section is the 91,660-acre planning area. The 91,660-acre planning area is further subdivided into the four Subarea Plan areas described in Chapter 1 (Figure 3-M). The Subareas total approximately 86,339 acres. The remaining 5,321 acres are comprised on the cities of Lake Forest and Dana Point, and internal areas that are “not a part” of the Subareas, such as Ladera Ranch, Las Flores, the wastewater treatment plant in lower Chiquita, Tesoro High School, FTC-North, and the Nichols Institute bounded by Caspers Wilderness Park. To describe the biological setting of the NCCP/MSAA/HCP planning area, this Chapter includes the following sections: Section 3.1 Database development methods; Section 3.2 Vegetation communities that make up theplanning area and the key wildlife species that are typical of, or indicate, high quality vegetation communities; Section 3.3 Existing geomorphic and hydrologic conditions and processes; Section 3.4 Sensitive wildlife and plant species distribution in the planning areaand subarea plan areas; and Section 3.5 Regional and subregional wildlife habitat linkages. -
Sec 05 11 Tribal and Cultural Resources
Tribal and Cultural Resources 5.11 TRIBAL AND CULTURAL RESOURCES 5.11.1 PURPOSE This section identifies existing cultural (including historic and archeological resources), paleontological and tribal resources within the Study Area, and provides an analysis of potential impacts associated with implementation of the General Plan Update. Potential impacts are identified and mitigation measures to address potentially significant impacts are recommended, as necessary. This section is primarily based upon the Cultural and Tribal Cultural Resources Technical Report for the Rancho Santa Margarita General Plan Update, Rancho Santa Margarita, Orange County, California (Cultural Study), and the Paleontological Resources Impact Assessment Report for the Rancho Santa Margarita General Plan Update, Orange County, California (Paleontological Assessment), both prepared by SWCA Environmental Consultants (SWCA) and dated April 2019; refer to Appendix F, Cultural/ Paleontological Resources Assessment. 5.11.2 EXISTING REGULATORY SETTING Numerous laws and regulations require Federal, State, and local agencies to consider the effects a project may have on cultural resources. These laws and regulations establish a process for compliance, define the responsibilities of the various agencies proposing the action, and prescribe the relationship among other involved agencies (i.e., State Historic Preservation Office and the Advisory Council on Historic Preservation). The National Historic Preservation Act (NHPA) of 1966, as amended, the California Environmental -
Watershed Summaries
Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working -
Southern Steelhead Populations Are in Danger of Extinction Within the Next 25-50 Years, Due to Anthropogenic and Environmental Impacts That Threaten Recovery
SOUTHERN CALIFORNIA STEELHEAD Oncorhynchus mykiss irideus Critical Concern. Status Score = 1.9 out of 5.0. Southern steelhead populations are in danger of extinction within the next 25-50 years, due to anthropogenic and environmental impacts that threaten recovery. Since its listing as an Endangered Species in 1997, southern steelhead abundance remains precariously low. Description: Southern steelhead are similar to other steelhead and are distinguished primarily by genetic and physiological differences that reflect their evolutionary history. They also exhibit morphometric differences that distinguish them from other coastal steelhead in California such as longer, more streamlined bodies that facilitate passage more easily in Southern California’s characteristic low flow, flashy streams (Bajjaliya et al. 2014). Taxonomic Relationships: Rainbow trout (Oncorhynchus mykiss) historically populated all coastal streams of Southern California with permanent flows, as either resident or anadromous trout, or both. Due to natural events such as fire and debris flows, and more recently due to anthropogenic forces such as urbanization and dam construction, many rainbow trout populations are isolated in remote headwaters of their native basins and exhibit a resident life history. In streams with access to the ocean, anadromous forms are present, which have a complex relationship with the resident forms (see Life History section). Southern California steelhead, or southern steelhead, is our informal name for the anadromous form of the formally designated Southern California Coast Steelhead Distinct Population Segment (DPS). Southern steelhead occurring below man-made or natural barriers were distinguished from resident trout in the Endangered Species Act (ESA) listing, and are under different jurisdictions for purposes of fisheries management although the two forms typically constitute one interbreeding population. -

Holy Fire Watershed Report
Burned Area Emergency Response Holy Fire Cleveland National Forest Hydrology and Watershed Specialist Report August 25, 2018 Overview of Horsethief Canyon above Interstate 15 Submitted by: Kelsha L. Anderson, Angeles National Forest Hydrologist I. Objectives This report summarizes the results from the hydrologic assessment of the Holy Fire in the center of the Santa Ana Mountains as part of the Burned Area Emergency Response (BAER). II Potential Values at Risk Values at Risk (VARs) on Forest Service land (FS) are addressed in Appendix D. Many VARs that could be impacted by the fire are on adjacent private, state, county, or local government lands. The State Watershed Emergency Response Team conducted a detailed analysis of non-FS VARs that will be published in a separate document. The FS BAER team and State WERT team collaborate and share information during post-fire assessments to ensure VARs are identified. On private lands, the primary contact for treatments is the USDA Natural Resources Conservation Service (NRCS). III. Resource Condition Assessment Fire and Site Description The Holy Fire started on August 06, 2018 at 1:30pm (suspected arson). As of August 21, 2018 the fire had burned 22,982 acres (90% contained). The burn occurred adjacent to California State Highway 74 and Interstate 15. Much of the Holy Fire last burned between 1940-80’s.

Lower San Juan Creek Watershed
Lower San Juan Creek Watershed Hydrologic Water Acreage Flows to Groundwater Jurisdictions Unit Name Planning Basin(s) Area Estrella Rafael/ Big 114,329 Salinas River via Paso Robles County of San Luis 17 Spring acres Estrella River – to Obispo WPA 11, Pacific Ocean Shandon (ptn) Salinas/ (Monterey Bay Los Padres National Estrella National Marine Forest Sanctuary) WPA 14 Description: The Lower San Juan Creek watershed is located in the eastern portion of the county to the north- west of the Carrizo Plains. The headwaters are located in the La Panza range with the highest point at approximately 3600-feet. The confluence of San Juan Creek with the Estrella River occurs at Shandon. The dominant land use is agriculture. The San Juan Creek Valley is generally used most intensively for agriculture because of better soils and water availability. Irrigated production has increased during the last 10 years, particularly in vineyards and alfalfa. Dry farming and grazing operations encompass the rest of the agricultural uses. The riparian forest and a portion of the adjacent upland areas associated with the Estrella River and San Juan Creek in the vicinity of Shandon are important wildlife habitat, and serve as important corridors for wildlife movement. San Joaquin kit fox and Western burrowing owl occur in open grasslands. Another important wildlife movement corridor is located near the base of the hillside near the eastern edge of Shandon.
