  • Master Plan of Trails, Adopted Oct
    P.O. BOX 8, SILVERADO, CA 92676 SMRPD Draft Master Plan of Trails, Adopted Oct. 14, 2004 The Master Plan of Regional Riding and Hiking Trails Component is countywide in scope. It is a public trail system which traverses the entire county without regard for jurisdictional boundaries and, therefore, intergovernmental coordination is necessary for successful implementation. -from the Recreation Element of the Orange County General Plan The Silverado Modjeska Community Plan and EIR (DEIR 096), prepared by the Environmental Planning Agency and distributed on November 23, 1976, included a variety of non-paved multi-use riding and hiking trails which were in place and inventoried at the time of the DEIR’s adoption. The plan allowed for the addition of recreational trails as proposed by the community. In 2002, under the jurisdiction of the Silverado Modjeska Recreation and Parks District (a State sanctioned Independent Special District), the community and the SMRPD worked together to create an updated Master Plan of Riding and Hiking Trails. As a conceptual plan, it is considered a general expression of community values and is abstract in nature. Purpose The purpose of the Silverado Modjeska Master Plan of Trails is to provide goals and objectives to direct the development and operation of a District-wide public trail system that serves the recreational needs of equestrians, pedestrians (walkers, hikers and joggers), and mountain bikers (non-motorized). Goals Goal 1: Provide a useful, enjoyable, safe, and efficient riding and hiking trail system for the District and to meet the needs and desires of the community. Goal 2: Create trail linkages between open space and recreation facilities, between community, municipal, state, and federal trail systems, and create connectivity to surrounding communities.

Santiago Creek Dam is a 136-foot-high rolled earth embankment located on Santiago Creek in Orange County, CA. Santiago Creek Dam forms Irvine Lake, which provides water supply to surrounding communities for both agricultural and municipal use. The outlet works and reinforced concrete spillway at Santiago Creek Dam were constructed in 1932. The dam and the reservoir are under the regulatory jurisdiction of the California Department of Water Resources, Division of Safety of Dams (DSOD). IRWD and SWD are implementing a long-term plan to replace the dam spillway and the outlet tower. Geotechnical investigations of the site are needed to inform the upcoming design phase for those facilities. The proposed geotechnical investigations will confirm the geotechnical and geologic conditions at the site and will provide a comprehensive understanding of the underlying geologic formations.

  • 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.

  • SP 12) Based on Multiple Evidence of Watershed-Wide Improvement (Option 2B)
    Improving Newport Bay Watersheds – Nutrients and Algae REPORTING WATERSHED IMPROVEMENT (SP 12) Based on Multiple Evidence of Watershed-wide Improvement (Option 2b) Executive Summary Two Newport Bay watersheds show watershed-wide improvement for nutrient impairments to water quality. Nutrient load reductions were achieved using a watershed approach that included both regulatory and non-regulatory mechanisms. These mechanisms were targeted to the three primary sources of nutrients in the watersheds: agriculture, urban runoff and large commercial nursery operations. Water quality data show total nitrogen concentrations have been reduced from highs of 140 mg/L recorded in the 1980s down to less than 2 mg/L today. Biological indicators of watershed health have also shown improvement including reduced algal blooms and increased eel grass populations.
