6.2 Hydrology and Water Quality 6.2 Hydrology and Water Quality 6.2 HYDROLOGY AND WATER QUALITY 6.2.1 Introduction This chapter describes water resources in the Planning Area, including major surface and groundwater resources and regulatory programs related to the protection of water quality. Water resources and infrastructure are discussed in Sections 3.1 and 3.2, respectively; and flooding issues and hazards are discussed in Section 7.2. The various sources used in the preparation of this chapter includes State, county, regional, and local resources such as the California Department of Water Resources, Los Angeles Regional Water Quality Control Board, Watersheds Coalition of Ventura County, Calleguas Municipal Water District, and the Ventura County Watershed Protection District. Calleguas Creek Watershed Simi Valley is located within the Calleguas Creek Watershed (Watershed). The Watershed encompasses approximately 343 square miles, predominantly in southern Ventura County, and is located along an east-west axis, approximately 30 miles long and 14 miles wide, as shown in Figure 6.2-1 (Groundwater Basins and Watersheds). The northern boundary is formed by South Mountain and Oak Ridge, the northeast and east boundary is formed by the Santa Susana Mountains, and the southern boundary is formed by the Simi Hills and Santa Monica Mountains. The Watershed includes Conejo Creek, Arroyo Santa Rosa, Arroyo Simi, Arroyo Las Posas, and Calleguas Creek, as well as Revolon Slough and Mugu Lagoon.159 Approximately 50 percent of the Watershed is undeveloped open space, 25 percent is agricultural, and the remaining 25 percent is urban land use.160 The Watershed is semi-arid, receiving an average of 15 inches of rainfall per year (at Moorpark) with a historical annual range of 6 inches to over 30 inches. Nearly all of the rainfall occurs between November and March.161 Simi Valley receives an average of 14.37 inches of rainfall per year.162 The upper reach of the Watershed includes Simi Valley and Las Posas Valley. The main surface water bodies are the Arroyo Simi, Arroyo Las Posas and the uppermost reach of the Calleguas Creek. The groundwater bodies include the Las Posas Basin, one of the major aquifers within the Fox Canyon Aquifer System, and the South Las Posas Basin and the Simi Valley Basin, both unconfined groundwater basins (Figure 6.2-1). Development on the northern reach includes the City of Simi Valley, the City of Moorpark, and some 19,000 acres of irrigated agriculture.163 159 Calleguas Municipal Water District. 2004.

Simi Valley General Plan Update Technical Background Report 6.2-1 Chapter 6 Natural Resources 6.2.2 Existing Conditions Surface Water The Watershed has relatively few surface water features. There are no natural lakes and no major rivers. The surface waters are primarily arroyos and creeks that have historically carried storm flows and post-storm flows from the upper watershed down to the alluvial valleys and the southeastern portion of the Oxnard Plain.164 The major drainage course through the City of Simi Valley is the Arroyo Simi. This major channel drains from the extreme limits of the watershed in the east and northeast, then westerly through the Las Posas Valley (as Arroyo Las Posas) to the Oxnard Plain (as Calleguas Creek), and finally into the Pacific Ocean through Mugu Lagoon.165 In the eastern half of the valley, the Arroyo Simi traverses close to the base of the hills on the southern edge of the valley, while in the western half it traverses diagonally across the valley to the northwest, reaching the center of the valley from which it discharges downstream toward Moorpark.166 Tributaries to Arroyo Simi from the Santa Susana Mountains on the north are, from west to east, Alamos Canyon, Brea Canyon, North Simi Drain, Dry Canyon, Tapo Canyon, Chivo Canyon, and Las Llajas Canyon. Canyons draining the Simi Hills from the south are Sycamore Canyon, Bus Canyon, Erringer Road Drain, Runkle Canyon, Meier Canyon and Black Canyon in the Santa Susana area.167 Surface Water Quality Issues Surface water quality within the City is affected by a variety of different discharges from both point and nonpoint sources. Wastewater treatment plant effluent is the largest and most common point-source discharge. Urban runoff, erosion, agricultural runoff, and other natural causes are common nonpoint sources. Pollutants from both point and nonpoint sources include total dissolved solids (TDS), suspended solids, oil, grease, nutrients (nitrogenated and phosphorated compounds), metals, bacteria, and pesticides. As discussed in the Regulatory Setting, Total Maximum Daily Loads (TMDLs) have been established to address surface water quality issues for chloride and nitrates and effects. Most of the surface waters within the Watershed have been identified by water quality regulators as impaired (conditions are inadequate to support beneficial uses as designated by the Regional Water Quality Control Board). The impaired uses include drinking water, aquatic life support, and recreation. The most significant sources of impairment are generally considered to be nonpoint sources of toxic pollutants, nitrogen, sediments, and algae. Point sources are also identified as potential sources of toxic 164 Ibid. 165 Ventura County Watershed Protection District. 2003.

Aquatic life in both Mugu Lagoon and the inland streams of this Watershed has been impacted by pollutants from nonpoint sources. Chemicals such as DDT, PCBs, other pesticides, and some metals have been detected in both sediment and biota collected from surface waterbodies of this Watershed. Additionally, ambient toxicity has been revealed in several studies from periodic toxicity testing in the Watershed [ammonia from Publicly Owned Treatment Works (POTWs) and pesticides such as diazinon and chlorpyrifos are implicated]. Fish collected from Calleguas Creek and Revolon Slough exhibit skin lesions and have been found to have other histopathologic abnormalities. High levels of minerals and nitrates are common in the water column as well as in the groundwater. Sediment toxicity is also elevated in some parts of the lagoon.

  • A History of Mexican Workers on the Oxnard Plain 1930-1980
    LABOR, MIGRATION, AND ACTIVISM: A HISTORY OF MEXICAN WORKERS ON THE OXNARD PLAIN 1930-1980 By Louie Herrera Moreno III A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for a degree of DOCTOR OF PHILOSOPHY Chicano/Latino Studies 2012 ABSTRACT LABOR, MIGRATION, AND ACTIVISM: A HISTORY OF MEXICAN WORKERS ON THE OXNARD PLAIN 1930-1980 By Louie Herrera Moreno III First and foremost, this dissertation focuses on the relationship between labor and migration in the development of the City of Oxnard and La Colonia neighborhood. Labor and migration on the Oxnard Plain have played an important part in shaping and constructing the Mexican working-class community and its relationship to the power structure of the city and the agri-business interests of Ventura County. This migration led to many conflicts between Mexicans and Whites. I focus on those conflicts and activism between 1930 and 1980. Secondly, this dissertation expands on early research conducted on Mexicans in Ventura County. The Oxnard Plain has been a key location of struggles for equality and justice. In those struggles, Mexican residents of Oxnard, the majority being working- class have played a key role in demanding better work conditions, housing, and wages. This dissertation continues the research of Tomas Almaguer, Frank P. Barajas, and Martha Menchaca, who focused on class, race, work, leisure, and conflict in Ventura County. Thirdly, this dissertation is connected to a broader history of Mexican workers in California. This dissertation is influenced by important research conducted by Carey McWilliams, Gilbert Gonzalez, Vicki Ruiz, and other historians on the relationship between labor, migration, and activism among the Mexican working-class community in Southern California.

  • Three Chumash-Style Pictograph Sites in Fernandeño Territory
    THREE CHUMASH-STYLE PICTOGRAPH SITES IN FERNANDEÑO TERRITORY ALBERT KNIGHT SANTA BARBARA MUSEUM OF NATURAL HISTORY There are three significant archaeology sites in the eastern Simi Hills that have an elaborate polychrome pictograph component. Numerous additional small loci of rock art and major midden deposits that are rich in artifacts also characterize these three sites. One of these sites, the “Burro Flats” site, has the most colorful, elaborate, and well-preserved pictographs in the region south of the Santa Clara River and west of the Los Angeles Basin and the San Fernando Valley. Almost all other painted rock art in this region consists of red-only paintings. During the pre-contact era, the eastern Simi Hills/west San Fernando Valley area was inhabited by a mix of Eastern Coastal Chumash and Fernandeño. The style of the paintings at the three sites (CA-VEN-1072, VEN-149, and LAN-357) is clearly the same as that found in Chumash territory. If the quantity and the quality of rock art are good indicators, then it is probable that these three sites were some of the most important ceremonial sites for the region. An examination of these sites has the potential to help us better understand this area of cultural interaction. This article discusses the polychrome rock art at the Burro Flats site (VEN-1072), the Lake Manor site (VEN-148/149), and the Chatsworth site (LAN-357). All three of these sites are located in rock shelters in the eastern Simi Hills. The Simi Hills are mostly located in southeast Ventura County, although the eastern end is in Los Angeles County (Figure 1).

  • 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

  • Practice Areas in the Los Angeles Basin
    Practice Areas in the Los Angeles Basin •The Los Angeles TERMINAL CHART includes 13 Flight Training areas indicated by a magenta CAUTION BLOCK containing the area title, altitude, and frequency. •The boundaries of these areas are not charted. However, SCAUWG has drawn candidate or general guideline boundaries in this presentation. These boundaries are shown in many FAAST seminars. •These data are provided solely as a guide for pilots flying in the Los Angeles Basin. They do not represent fixed boundaries or other regulatory airspace designated or defined by the FAA. The “legal stuff” … There are 13 areas in the Los Angeles Basin used for practice by students as well as pilots working on enhanced ratings – and in at least three cases, aerobatic training. This presentation was developed by Al German, CFI (retired), while working with Orange County Flight Center. The reference lines that designate the practice areas are general in nature and represent discussions by Mr. German with flight schools in each of the areas designated. This data is provided solely as a guide for pilots flying in the Los Angeles Basin and in no way, represents fixed boundaries or other regulatory airspace designated by the FAA. It is made available for use by pilots by Mr. German and the Southern California Airspace Users Working Group. Original: 26 Feb 2001 Revised: : January 2012 Generally speaking, these practice areas are on the perimeters of various Class B or Class C airspace. So pilots in training must not only look out for each other; but must be aware of the traffic routes to-and-from these high-use designated airspaces.
