In 1999, the City applied for assistance through the National Park Service Rivers, Trails and Conservation Assistance program to create a conceptual master plan for Santiago Creek. Santiago Creek is one of the few open space corridors remaining in the City, and is a significant community resource. The purpose of creating a vision plan is to create a community vision for the creek. The plan will address three major components—greenway, floodway and trail. The role of the National Park Service will be to facilitate the public process and help create the Master Plan.
