The project consists of a proposal to develop an approximately 237.25 gross acre property as a master-planned community comprised of 753 single family residential lots, two neighborhood park sites, and an open space area serving storm water detention and water quality filtration purposes. The proposed five residential neighborhoods (planning areas A, B, C, D, and E) would accommodate a max of 753 single family residential homes at a gross density of 3.2 dwelling units per acre. Two neighborhood parks are designed to serve as activity nodes and social gathering spaces, sized at 4.1 and 6.3 acres. Proposed along the west side of the proposed 65th Street west in the center of the community is a 12.1-acre open space area, which would serve storm water detention and water quality filtration purposes. The principal discretionary actions required of the City of Lancaster to implement the proposed Project include the approval of: the Avanti North Specific Plan that would authorize a master-planned community in accordance with the City of Lancaster's General Plan "Urban Residential with Specific Plan overlay" designation. The Avanti North Specific Plan would accommodate a maximum of 753 single-family residential homes, two private parks, and open space proposed for the use of stormwater detention, on 237.25 gross-acres with an average residential density of 3.17 (rounded up to 3.2) dwelling units per acre (du/ac); and Tentative Tract Map No. 73507 that would implement the Avanti North Specific Plan.
