Dana Reserve Specific Plan

The 2024 Dana Reserve Specific Plan  would allow for the phased development of a 288-acre master-planned community with up to 1,370 residential units, 110,000-203,000 square feet of commercial and non-residential (Visitor Serving/Hotel, Education) floor area, a minimum of 55.6 acres of open space and 6.3 acres of recreation, and related circulation and infrastructure. The project also includes a County-initiated General Plan and Ordinance Amendment to change the land use categories within the specific plan area and to incorporate the property into the Nipomo Urban Reserve Line (URL), and to ensure the General Plan is consistent with the DRSP. The project would require annexation into the Nipomo Community Services District service area to facilitate the provision of water and wastewater services to the project. The project site is located in the Residential Rural land use category, west of US 101, east of Hetrick Avenue, and adjacent to the Nipomo URL. The project is located within the South County Inland Sub Area of the South County Planning Area.
