Document Description
Elworthy West, LLC proposes the development of a portion of a 459-acre site located on the west side of San Ramon Valley Boulevard in the southwest quadrant of Danville. The project would develop approximately 12 acres of the project site with 84 two-story single-family residences and two two-story buildings containing a total of 12 multi-family apartment units, including five units that would be affordable to very low income households. Included within the 12-acre development area would be a community pool, barbecue area and tot-lot. An existing single-family residence would be retained on a separate five-acre parcel. Of the remaining 442 acres, 232 acres would be offered for dedication to the East Bay Regional Park District (EBRPD), 186 acres would have a scenic easement established to preserve the area for open space and limited recreational use, and 24 acres would be set aside as a mitigation site. A trailhead parking area as well as a private equestrian facility, proposed on approximately five acres, would be located within the scenic easement area. Frontage improvements, including widening along San Ramon Valley Boulevard are also proposed.
