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 -

Initial Study with Proposed Mitigated Negative Declaration/Environmental Assessment for the SR 55 Improvement Project Between I
Chapter 2 Affected Environment, Environmental Consequences, and Avoidance, Minimization, and/or Mitigation Measures PHYSICAL ENVIRONMENT 2.8 Hydrology and Floodplains 2.8.1 Regulatory Setting EO 11988 (Floodplain Management) directs all federal agencies to refrain from conducting, supporting, or allowing actions in floodplains unless it is the only practicable alternative. The FHWA requirements for compliance are outlined in 23 CFR 650 Subpart A. To comply, the following must be analyzed: • The practicability of alternatives to any longitudinal encroachments • Risks of the action • Impacts on natural and beneficial floodplain values • Support of incompatible floodplain development • Measures to minimize floodplain impacts and to preserve/restore any beneficial floodplain values affected by the project The base floodplain is defined as “the area subject to flooding by the flood or tide having a one percent chance of being exceeded in any given year.” An encroachment is defined as “an action within the limits of the base floodplain.” 2.8.2 Affected Environment This section is based on the Location Hydraulic Study State Route 55 Improvement Project From Interstate 5 to State Route 91 (LHS) (April 2018), the Water Quality Technical Memorandum (November 2018), Stormwater Data Report (March 2019), and the Preliminary Drainage Report State Route 55 Widening Project (October 2018) prepared for the proposed project. 2.8.2.1 Regional Hydrology The proposed project is located within the Santa Ana River hydrologic unit and within two subhydrologic areas: the Lower Santa Ana River and San Diego Creek, both of which are part of the East Coastal Plain Hydrologic Sub-Area (801.11). In addition, the proposed project is located within three watersheds: the Lower Santa River Watershed, Santiago Creek Watershed, and San Diego Creek Watershed. -

5.4 Hydrology and Water Quality City of Lake Forest Portola Center Project Subsequent Environmental Impact Report 5.4 HYDROLOGY AND WATER QUALITY This section analyzes potential project impacts on existing drainage patterns, surface hydrology, and flood control facilities and water quality conditions in the project area. Mitigation measures are recommended to avoid potential impacts or reduce them to a less than significant level. The discussion in this section is based on information and conclusions contained in the following studies: . Hydrology Study for TTM 15353 & 17300 (Hydrology Study), prepared by Hunsaker & Associates Irvine, Inc., dated February 19, 2013; refer to Appendix 11.4, Hydrology and Water Quality Assessment. Water Quality Management Plan (WQMP) for Portola Center Tentative Tract Map No. 15353 Lake Forest, CA (WQMP TTM 15353) prepared by Hunsaker and Associates Irvine, Inc., dated March 18, 2013; refer to Appendix 11.4, Hydrology and Water Quality Assessment. Water Quality Management Plan (WQMP) for Portola Center Tentative Tract Map No. 17300 Lake Forest, CA (WQMP TTM 17300) prepared by Hunsaker and Associates Irvine, Inc., dated March 18, 2013; refer to Appendix 11.4, Hydrology and Water Quality Assessment. 5.4.1 EXISTING SETTING HYDROLOGY AND DRAINAGE CONDITIONS The project site is located within the Aliso Creek and San Diego Creek (also referred to as the Newport Bay) Watersheds. TTM 15353 is located completely within the Aliso Creek Watershed. A majority of TTM 17300 (approximately 98.1 acres) is located within the Aliso Creek Watershed and the remaining area (1.4 acres) is located within the San Diego Creek Watershed. More specifically, the 1.4 acres is in the Serrano Creek drainage area of Watershed F, San Diego Creek Subwatershed. -
LWHC Once Upon Laguna Woods
Once Upon Laguna Woods by Dean O. Dixon Once upon a time in a magical land there were fiery volcanos, roiling seas, and fearsome animals. Then came warriors, conquerors, banishment, empires, slaves, wars, pirates, corruption, bandits, posses, lynching, ghosts, invasion, exploitation, riches, scandal and, yes, even happily ever after. Fiction? No. These are true stories about the land right under your feet in and around Laguna Woods. So what did happen once upon Laguna Woods? Well, are you up for some time travel? The beloved natural vistas from Laguna Woods reflect decades of conservation efforts that preserved tens of thousands of pristine acres from any future human development. You get to enjoy this in perpetuity without it ever being disturbed. Woods End Wilderness Preserve, Laguna Coast Wilderness Park, Aliso & Wood Canyons Wilderness Park, Crystal Cove State Park, Laguna Niguel Regional Park, and City of Irvine Open Space Preserve are contiguous in a synergistic display of your natural history. But what exactly do you see? Once Upon Laguna Woods February 27, 2016 page !2 of !60 Natural erosion has exposed up to 65 million years of rock strata laid down and compressed one layer atop another by eons of changes in the earth’s crust as influenced by climate, flora and fauna. Sand from deserts and beaches, mud from swamps and rivers, skeletons of sea and land creatures, recurrences of these, and still more are solidified and revealed like layers in a slice of cake for the delight of geologists and further study by anyone so inclined. Related tectonics further changed and are changing your area even today as the Atlantic Plate pushes the North American Plate westward into the Pacific Plate along that constant worry of yours, the San Andreas Fault. -
3.4 Biological Resources
3.4 Biological Resources 3.4 BIOLOGICAL RESOURCES 3.4.1 Introduction This section evaluates the potential for implementation of the Proposed Project to have impacts on biological resources, including sensitive plants, animals, and habitats. The Notice of Preparation (NOP) (Appendix A) identified the potential for impacts associated to candidate, sensitive, or special status species (as defined in Section 3.4.6 below), sensitive natural communities, jurisdictional waters of the United States, wildlife corridors or other significant migratory pathway, and a potential to conflict with local policies and ordinances protecting biological resources. Data used to prepare this section were taken from the Orange County General Plan, the City of Lake Forest General Plan, Lake Forest Municipal Code, field observations, and other sources, referenced within this section, for background information. Full bibliographic references are noted in Section 3.4.12 (References). No comments with respect to biological resources were received during the NOP comment period. The Proposed Project includes a General Plan Amendment (GPA) and zone change for development of Sites 1 to 6 and creation of public facilities overlay on Site 7. 3.4.2 Environmental Setting Regional Characteristics The City of Lake Forest, with a population of approximately 77,700 as of January 2004, is an area of 16.6 square miles located in the heart of South Orange County and Saddleback Valley, between the coastal floodplain and the Santa Ana Mountains (see Figure 2-1, Regional Location). The western portion of the City is near sea level, while the northeastern portion reaches elevations of up to 1,500 feet. -
