Document Description
This proposed project would provide an outdoor recreational facility in the San Francisco Bay Area for The Mosaic Project’s primary program, its Outdoor Project. The Mosaic Project’s mission with The Outdoor Project Camp is to work toward a peaceful future by uniting children of diverse backgrounds, providing them with community building skills, and empowering them to become peacemakers through a multi-day nature-oriented experience. The proposed project would consist of demolishing an existing 7,500-square-foot garage, improving trails and miscellaneous dirt or gravel roads, and constructing components critical to the proposed project’s mission. These components include twelve 400-square-foot camping cabins; an 8,500-square-foot central meeting and dining hall; a 1,025-square-foot restroom/shower building; a two-story 2,600-square-foot staff housing building; and sewer infrastructure that includes an on-site septic tank with a leach field dispersal system. An existing 1,200-square-foot caretaker’s unit would continue to be utilized, as well as on-site groundwater wells. The proposed project, including all recreational facilities and caretaker residences, would encompass an area totaling 2 acres.
