  • Section 5.15: Water Supply
    General Plan Update Section 5.15: Water Supply This section analyzes projected impacts to water supplies and distribution systems that may result from the implementation of the proposed General Plan 2035. The purpose of this analysis is to document and describe the existing water supply, water consumption, and distribution infrastructure in the City of Murrieta, and to evaluate impacts associated with buildout of the proposed General Plan 2035. This section is based upon information from the Eastern Municipal Water District (refer to Appendix L1); Elsinore Valley Water District (refer to Appendices M1, M2, and M3); Rancho California Water District (refer to Appendices N1, N2, and N3); and Western Municipal Water District (refer to Appendices O1 and O2). The Clean Water Act (CWA) is a Federal law intended to protect surface waters of the United States (U.S.), which include lakes, rivers, coastal wetlands, and “waters of the U.S.” The CWA regulates all discharges to waters, which are considered illegal unless authorized by an appropriate permit. Discharge of dredged and fill materials, construction-related storm water discharges, and other activities that may result in discharges of pollutants to waters of the U.S. are regulated by the permit. If waters of the U.S. are located on a project site, the project is likely to discharge to them, due to site topography and/or drainage characteristics. Potential discharges to such waters would be considered an impact, and the applicant would be required to obtain a CWA Section 401 Water Quality Certification from the appropriate Regional Water Quality Control Board (RWQCB).

  • Environmental Setting 2
    2.0 Environmental Setting 2 Chapter 2 Environmental Setting 2.1 Planning Context 2.1.1 Project Location The city of Moreno Valley (city) is located within the northwestern portion of Riverside County in the southern Inland Empire portion of the state of California. Moreno Valley is located approximately 63 miles east of downtown Los Angeles, 49 miles east of the city of Irvine, and 43 miles west of the city of Palm Springs. State Route 60 (SR-60), which runs in an east and west direction through the northern portion of Moreno Valley (east and west direction), and Interstate 215 (I-215), which runs in proximity to the westerly city limits (north and south direction), serve to connect the city to other communities throughout the southern California region. The city is accessible via public transportation by rail, through Metrolink located approximately one-half mile west of the city limits, and the city is accessible via aircraft at the Inland Port Airport located at the March Air Reserve Base (MARB), which is situated south and west of the city limits. The city’s picturesque valley setting is bounded to the north by the Box Springs Mountains, the Badlands to the east, and the mountains of the Lake Perris Recreation Area, Mystic Lake floodplain, and San Jacinto Wildlife Area to the south. The city is also bounded by MARB to the southwest and the city of Riverside to the west. Moreno Valley is a diverse and growing community of approximately 207,000 people. It has a relatively young and dynamic majority Latino population.

  • The Status and Distribution of the Freshwater Fishes of Southern California
    Bull. Southern California Acad. Sci. 92(3), 1993, pp. 101-167 CO Southern California Academy of Sciences, 1993 The Status and Distribution of the Freshwater Fishes of Southern California Camm C. Swift,' Thomas R. Haglund,2 Mario Ruiz,' and Robert N. Fisher3 Section of Fishes, Natural History Museum, 900 Exposition Boulevard, Los Angeles, California 90007 2Department of Biology, University of California, Los Angeles, California 90024-1606 r 3 Section of Zoology and Center for Population Biology, • 4 iTh University of California, Davis, California 95616 Abstract. —The fresh and low salinity waters of southern California include the Owens, Mohave, Colorado, and coastal drainages south of Monterey Bay to -the Mexican border. The youthful topography presents a strong dichotomy between steep rocky streams abruptly meeting relatively flat deserts or coastal plains. Little or no intermediate, foothill habitat exists. Thirty-eight native freshwater and 23 estuarine fishes have been recorded from this area. In addition, at least 100 species have been introduced, with widely varying success. Since the late 1940s and 1950s the native fishes of the Owens, Colorado, and Mohave drainages have been in jeopardy or extirpated in California. At the same time, the lowland fishes in coastal drainages, particularly on the Los Angeles Basin, also disappeared. Upland species of the coastal drainages still remain in a few isolated areas but are so reduced that special protection is needed. Only one estuarine species, Eucyclogobius newberryi, is threatened. Some tropical estuarine species of extreme southern California were last collected 50 to 80 years ago, and are very rare or extirpated here. If the remaining elements of the fish fauna are to survive, immediate action is needed to preserve the remaining habitat and to restore areas within the native range.

  • Upper Santa Margarita Watershed IRWM Plan Update FINAL
    Region Description 2 Region Description The purpose of this chapter is to define the USMW Region through descriptions of its boundaries, water demands, supply sources, water quality, ecological and environmental processes, land uses, social characteristics, and economic trends and conditions. Understanding the unique nature of the USMW Region is key to developing truly meaningful IRWM planning needs, goals and objectives, resource strategies, and projects as described in subsequent chapters of this 2014 IRWM Plan Update. 2.1 Regional Boundaries 2.1.1 IRWM Boundaries The USMW IRWM Region covers an area of approximately 640 square miles (410,000 acres) in southwestern Riverside County, as shown in Figure 2-1. Its boundary is defined as the portions of the Santa Margarita River Watershed and the San Mateo Watershed that lie within Riverside County. The remaining portion of the Santa Margarita River Watershed lies within the adjacent San Diego IRWM Region to the south, and the remaining portion of the San Mateo Watershed lies within the adjacent South Orange IRWM Region to the west. The IRWM boundaries allow for full coverage of these watersheds without over-expanding the size of the planning area beyond stakeholders’ ability to participate. All three of these IRWM Regions compose the entire San Diego Funding Area. Figure 2-1: IRWM Region Location 2 - 1 2014 Upper Santa Margarita Watershed IRWM Plan Update FINAL Region Description 2.1.2 Watershed Boundaries Drainage in the basin is provided by the Upper Santa Margarita Watershed with flows from Temecula and Murrieta Creeks, and by portions of the Upper San Mateo Watershed with flows primarily from San Mateo Creek.

  • Hydrology, Drainage, and Water Quality
    General Plan Update Section 5.13: Hydrology, Drainage, and Water Quality This section describes the existing conditions related to hydrology, drainage, and water quality within the City of Murrieta. Hydrologic and drainage impacts that could result from implementation of the proposed General Plan 2035 are identified. The Clean Water Act (CWA) is a Federal law intended to protect surface waters of the United States (U.S.), which include lakes, rivers, coastal wetlands, and “waters of the U.S.” The CWA regulates all discharges to waters, which are considered illegal unless authorized by an appropriate permit. Discharge of dredged and fill materials, construction-related storm water discharges, and other activities that may result in discharges of pollutants to waters of the U.S. are regulated by the permit. If waters of the U.S. are located on a project site, the project is likely to discharge to them, due to site topography and/or drainage characteristics. Potential discharges to such waters would be considered an impact, and the applicant would be required to obtain a CWA Section 401 Water Quality Certification from the appropriate Regional Water Quality Control Board (RWQCB). The CWA specifies that discharges to waters are illegal, unless authorized by an appropriate permit. The permits regulate the discharge of dredged and fill materials, construction-related storm water discharges, and activities that may result in discharges of pollutants to “waters of the U.S.”. Section 404 of the CWA establishes a permit program for the discharge of dredge or fill materials into waters of the U.S. This permit program is administered by the U.S.
