  • 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.
