3.12 Hydrology and Water Quality
3.12 HYDROLOGY AND WATER QUALITY EXECUTIVE SUMMARY This section describes the drainage features, stormwater quality, flooding hazards, and flood-protection improvements within the City’s Planning Area. Regulatory agencies governing stormwater quality and flooding hazards are also discussed. The City’s Planning Area is comprised of the City’s boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is outside the City’s boundaries and adopted SOI. Together the City and County Planning Areas comprise the OVOV Planning Area. With implementation of the proposed General Plan goals, objectives, and policies potential impacts on hydrology and water quality would be less than significant. EXISTING CONDITIONS Surface Water Drainage Patterns within City’s Planning Area Surface water drainage patterns are dependent on topography, the amount and location of impervious surfaces, and the type of flood control that is located in an area. The size, or magnitude, of a flood is described by a term called a “recurrence interval.” By studying a long period of flow record for a stream, hydrologists estimate the size of a flood that would have a likelihood of occurring during various intervals. For example, a five-year flood event would occur, on the average, once every five years (and would have a 20 percent chance of occurring in any one year). Although a 100-year flood event is expected to happen only once in a century, there is a 1 percent chance that a flood of that size could happen during any year. -
History: Before the Poppy Reserve
History: Before the Poppy Reserve The Kitanemuk, members of the Shoshonean Linguistic Group lived in the area between Fairmont and Antelope Buttes: “one of the largest and most significant archaeological sites in the Antelope Valley” • Source: http://www.avim.parks.ca.gov/people/ph_kitanemuk.s html The Kitanemuk, like other groups on the mountain margins of the Mojave Desert, lived in permanent winter villages of 50 to 80 people or more. These people dispersed into smaller mobile gathering groups during the late spring, summer, and fall months. The smaller groups made use of temporary camps for relatively short times, visiting different "environmental niches" as the important food-producing plants in them became ready to harvest. The Kitanemuk spoke a language that appears to have been a dialect of Serrano, which was spoken by groups located as far distant as modern Yucca Valley and Twenty- nine Palms, east of the San Bernardino Mountains.

A series of tables are presented below, organized first by jurisdiction and then by watershed. Index maps of the subwatershed IDs are presented in Appendix 7.B. The following color-gradients and symbol legend applies to all tables in Appendix 7A: RED = Subwatersheds with highest required % load reductions BLUE = Subwatersheds with highest BMP capacities within a BMP category --- = BMP opportunity was either not available or not selected for the subwatershed (a value of 0.00 means that BMP capacity is non-zero but less than 0.004).

Appendix a - Special Designation Overlays - Angeles National Forest
Appendix A - Special Designation Overlays - Angeles National Forest Monument Existing National Monuments Saint Francis Dam Disaster Places: Santa Clara Canyon 353 Acres Located within San Francisquito Canyon, the Saint Francis Dam Disaster National Memorial and Monument was designated on March 12, 2019 by the John D. Dingell, Jr. Conservation, Management, and Recreation Act, Sec. 1111, which also authorized the establishment of a future Saint Francis Dam Disaster National Memorial. This legislation was signed exactly 91 years after the 200-foot high Saint Francis Dam broke, sweeping away over 400 victims and scouring the floodplain for 52 miles until it emptied into the Pacific Ocean. The purpose of the Monument is to conserve and enhance for the benefit and enjoyment of the public the cultural, archaeological, historical, watershed, educational, and recreational resources and values of the Monument. The Memorial would be the first national memorial managed by the Forest Service and is intended to honor the victims and memorialize the history of the Saint Francis Dam Disaster. San Francisquito Canyon is known for its significant historical associations and values, not only from a Tribal and Native American historical context, but because of the important use of this area during the Spanish, Mexican, and Early American periods. The first anthropologic and ethnographic recording of Native American communities identified the Tataviam as occupying the San Francisquito Canyon. While early physical evidence of their occupation of the area is scarce, early ethnographic and mission records, along with some archaeological evidence indicates their presence and use of the area ranges from 3,500 to 7,500 years ago, and likely even earlier. -

Sites Reservoir Project Public Draft EIR/EIS
6. Surface Water Resources 6.1 Introduction This chapter describes Existing Conditions (the environmental setting) and Sites Reservoir Project (Project)-related changes to surface water resources in the Extended, Secondary, and Primary study areas. Detailed descriptions and maps of these three study areas are provided in Chapter 1 Introduction, and summarized descriptions are included in this chapter. Surface water resources generally include reservoirs, rivers, and diversions. Permits and authorizations for surface water resources are presented in Chapter 4 Environmental Compliance and Permit Summary. The regulatory setting for surface water resources is presented in Appendix 4A Environmental Compliance. This chapter also includes a description of the surface water supply facilities operations and resulting surface water resources characteristics of California’s major water systems that are relevant to the Project: the Central Valley Project (CVP), a federal project that is operated and maintained by the Bureau of Reclamation (Reclamation), the State Water Project (SWP), operated and maintained by the California Department of Water Resources (DWR), and associated tributary rivers and streams. A schematic showing the layout of these two water systems, with the relative location of the Project, is shown in Figures 6-1A, 6-1B, and 6-1C. A comparison of these characteristics has been made between the Existing Conditions/No Project/No Action Condition, and the four action alternatives (Alternatives A, B, C, and D). Unless noted, all numbers shown related to storages, flows, exports, and deliveries in this chapter are generated from the CALSIM II computer simulation model. Appendix 6A Modeling of Alternatives, Appendix 6B Water Resources System Modeling, and Appendix 6C Upper Sacramento River Daily River Flow and Operations Modeling describe the assumptions and the analytical framework used in the surface water modeling analyses. -
Iv. Environmental Impact Analysis I. Public Utilities 1
IV. ENVIRONMENTAL IMPACT ANALYSIS I. PUBLIC UTILITIES 1. WATER ENVIRONMENTAL SETTING Regional Water Supply Water is currently supplied to the Project Site by the City of Los Angeles Department of Water and Power (LADWP). The LADWP is responsible for ensuring that water demands within the City are met and that State and Federal water quality standards are achieved. For the fiscal year of 2003-2004, City water supplies were derived from the following sources: (1) the Los Angeles Aqueduct, approximately 33 percent; (2) groundwater, approximately 14 percent; (3) purchases from the Metropolitan Water District (MWD), approximately 53 percent; and (4) recycled water, less than 1%.1 The amount of water obtained from these sources varies from year to year, and is primarily dependent on weather conditions and demand. In addition, reclamation of wastewater is utilized for certain irrigation purposes. Water storage is essential for the LADWP to supply water during high demand conditions and provide for firefighting and emergencies. The City water system has 104 tanks and reservoirs ranging in size from ten thousand to 60 billion gallons with a total capacity of 109 billion gallons.2 The LADWP has instituted significant water conservation measures in addition to State level regulations including: • City Ordinance 165,004 – Reduces water consumption by requiring new buildings to install water conservation fixtures, such as ultra low-flush toilets, urinals, taps, and showerheads, and plumbing fixtures that reduce water loss from leakage in order to obtain building permits in the City of Los Angeles. In addition, there are provisions requiring xeriscaping – the use of low- maintenance, drought-resistant plants. -
