5.4 Hydrology and Water Quality
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. -

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. -

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 -

District County (Prefix, Agency Code, Project No.) Location 12 ORA BRLO-5955 (087) Ladd Canyon and Santiago Road, Community of Silverado For Local Assistance projects off the highway system, use headers in italics Project Description: Orange County Public Works proposes to remove and replace the existing Silverado Canyon Road over Ladd Creek Bridge (Ladd Canyon Bridge) (Bridge Number 55C0175) at a location slightly east of the intersection of Ladd Canyon Road and Silverado Canyon Road (proposed Project). The proposed Project will remove the existing Ladd Canyon Bridge and replace with a new bridge, perform required grading within the vicinity of the bridge in order to tie into the existing slopes, and provide drainage improvements where feasible. In order to provide for the temporary parking of construction equipment and construction employee vehicles and the storage of construction supplies, the proposed Project includes three staging areas along Silverado Canyon Road to the west of the existing bridge. Silverado Canyon Road will be used to transfer the supplies from the staging areas to the Project area. Based on the findings of an in-depth inspection of the bridge conducted by the County, in coordination with Caltrans, the existing Ladd Canyon Bridge has been classified as consist of a pre-cast concrete bridge that provides an expansion from the existing bridge width to provide safe conditions for vehicular traffic and pedestrian access. -

Section 5.8 Hydrology, Drainage, and Water Quality
Section 5.8 Hydrology, Drainage, and Water Quality SECTION 5.8 HYDROLOGY, DRAINAGE, AND WATER QUALITY This section describes the existing hydrological and water quality conditions within the City of Buena Park. The potential impacts that could result from implementation of the proposed General Plan Update are analyzed, and where significant impacts are identified, mitigation measures are recommended to avoid or reduce these impacts to a less than significant level. This section includes information contained in the Hydrology Impact and Water Quality Assessment prepared by RBF Consulting (February 2010) (Appendix F). 5.8.1 EXISTING SETTING GROUNDWATER The City relies on two major water supply sources, which include imported water from the Metropolitan Water District (MWD) and local groundwater from the Orange County Groundwater Basin, managed by the Orange County Water District (OCWD). The groundwater basin receives water via the Santa Ana River. Each year OCWD sets a basin production percentage (BPP) for the agencies that pump from the basin. The BPP is the ratio of water produced from the groundwater to all water produced by the agency. The BPP provides a limit on how much each agency can pump from the Orange County Groundwater Basin without paying a penalty. According to the City of Buena Park 2005 Water Master Plan Study Final Report (Water Master Plan) (February 2007), the City’s basin pumping percentage is 66 percent and is anticipated to increase to the historical value of 75 percent. However, water supply conditions have changed over recent years and according to the City’s Public Works Department, the current BPP is 62 percent and the BPP is not anticipated to rise above the current rate for a number of years.
