Quality Workplan ("Watershed Workplan") has been developed in compliance with Directive G of the San Diego Regional Water Quality Control Board's (Regional Board) Order No. R9‐2010‐0016. The Watershed Workplan addresses the Santa Margarita Region, which is that portion of the Upper Santa Margarita River Watershed within Riverside County. Order No. R9‐2010‐ 0016 was adopted on November 10, 2010 and provides the Waste Discharge Requirements for Discharges from the Municipal Separate Storm Sewer Systems (MS4s) for the County of Riverside (County), the City of Temecula, the City of Murrieta, the City of Wildomar, and the Riverside County Flood Control and Water Conservation District (District), referred to simply as the "2010 MS4 Permit" in the remainder of this document.

(Photo credit: American Red Cross) Opposite Page: Painting of Harris Fire by Kate Dore, based on photo by Wes Schultz. 2 Introductory Statement In October of 2007, a series of large wildfires ignited and burned hundreds of thousands of acres in Southern California. The fires displaced nearly one million residents, destroyed thousands of homes, and sadly took the lives of 10 people. Shortly after the fire siege began, a team was commissioned by CAL FIRE, the U.S. Forest Service and OES to gather data and measure the response from the numerous fire agencies involved. This report is the result of the team’s efforts and is based upon the best available information and all known facts that have been accumulated. In addition to outlining the fire conditions leading up to the 2007 siege, this report presents statistics —including availability of firefighting resources, acreage engaged, and weather conditions—alongside the strategies that were employed by fire commanders to create a complete day-by-day account of the firefighting effort. The ability to protect the lives, property, and natural resources of the residents of California is contingent upon the strength of cooperation and coordination among federal, state and local firefighting agencies.

  • 4 Tribal Nations of San Diego County This Chapter Presents an Overall Summary of the Tribal Nations of San Diego County and the Water Resources on Their Reservations
    4 Tribal Nations of San Diego County This chapter presents an overall summary of the Tribal Nations of San Diego County and the water resources on their reservations. A brief description of each Tribe, along with a summary of available information on each Tribe’s water resources, is provided. The water management issues provided by the Tribe’s representatives at the San Diego IRWM outreach meetings are also presented. 4.1 Reservations San Diego County features the largest number of Tribes and Reservations of any county in the United States. There are 18 federally-recognized Tribal Nation Reservations and 17 Tribal Governments, because the Barona and Viejas Bands share joint-trust and administrative responsibility for the Capitan Grande Reservation. All of the Tribes within the San Diego IRWM Region are also recognized as California Native American Tribes. These Reservation lands, which are governed by Tribal Nations, total approximately 127,000 acres or 198 square miles. The locations of the Tribal Reservations are presented in Figure 4-1 and summarized in Table 4-1. Two additional Tribal Governments do not have federally recognized lands: 1) the San Luis Rey Band of Luiseño Indians (though the Band remains active in the San Diego region) and 2) the Mount Laguna Band of Luiseño Indians. Note that there may appear to be inconsistencies related to population sizes of tribes in Table 4-1. This is because not all Tribes may choose to participate in population surveys, or may identify with multiple heritages. 4.2 Cultural Groups Native Americans within the San Diego IRWM Region generally comprise four distinct cultural groups (Kumeyaay/Diegueno, Luiseño, Cahuilla, and Cupeño), which are from two distinct language families (Uto-Aztecan and Yuman-Cochimi).

  • Introduction
    Chapter 1: Introduction 1.1 OVERVIEW The Murrieta General Plan is a document required by California law that provides a foundation for City policies and actions. It guides both the physical development of Murrieta and the provision of public infrastructure and services. This General Plan places particular emphasis on economic development and keeps Murrieta in front of current policy topics, including sustainability and health. It is rooted in ten community priorities that were developed through an extensive community involvement process. 1.2 ABOUT THE GENERAL PLAN GENERAL PLAN TOPICS California law requires each city and county to have an adopted General Plan. State law specifies that each jurisdiction’s General Plan address seven “elements,” or topics: land use, circulation, housing, conservation, open space, noise, and safety. Cities are also allowed to include additional elements on matters of particular importance within that community. The Murrieta General Plan includes the following chapters: Introduction: Purpose and contents of the General Plan, its relationship to California law, background on Murrieta, the planning process that was followed for the General Plan Update, and the community priorities that shaped the General Plan goals and policies. Vision: Context for the General Plan, including major policy initiatives behind the General Plan Update. Land Use Element: Growth, development, redevelopment, conservation, and preservation. Parameters and desired locations for land uses such as residential, commercial, industrial, civic/institutional, parks, and open space are mapped and described. Economic Development Element: Strength and diversity of the economy, jobs, retail, and revenue for public services. 1-1 Circulation Element: Transportation systems within the City that provide for automobile, truck, transit, bicycle, and pedestrian movement.

Groundwater basins that may be 16 affected by implementation of the alternatives are in the Trinity River Region, 17 Central Valley Region, San Francisco Bay Area Region, Central Coast Region, 18 and Southern California Region. 19 Actions located on public agency lands or implemented, funded, or approved by 20 Federal and state agencies would need to be compliant with appropriate Federal 21 and state agency policies and regulations, as summarized in Chapter 4, Approach 22 to Environmental Analyses. 23 Several of the state policies and regulations described in Chapter 4 have resulted 24 in specific institutional and operational conditions in California groundwater 25 basins, including the basin adjudication process, California Statewide 26 Groundwater Elevation Monitoring Program (CASGEM), California Sustainable 27 Groundwater Management Act (SGMA), and local groundwater management 28 ordinances, as summarized below.
