Background/Overview
A road and trail management plan provides specific direction for the long term construction, maintenance, and management of the road and trail system in a park. The need for the plan at Mount Diablo State Park was identified in the 1989 General Plan as follows:
To accommodate increase visitation at the park, and to manage and protect resource values, the Department of Parks and Recreation needs to undertake major programs of resource management, building restoration, and interpretation, to enhance existing facilities, and to open up other areas for visitor enjoyment. The department must also develop new opportunities and facilities for optimizing public enjoyment of the park’s natural, cultural, and recreational resources.
Mount Diablo SP has nearly 200 miles of official roads and trails and many miles of unofficial trails created over the years by park visitors. The plan provides the following information:RTMP Maps
