The Sierra Vista Landowner Group proposes to implement a large-scale, mixed-use, mixed-density master planned community with residential, commercial, office, public/quasi-public, and open space land uses, and parks. The Sierra Vista Specific Plan would include approximately 1,148 acres of residential uses; 281 acres of commercial, office, and commercial-mixed uses; 162 acres of parks and paseos; 83 acres of public/quasi-public land uses; 31 acres of urban reserve; and 190 acres of roadways and landscape corridors. The Specific Plan would also include 244 acres of open space; of these, 38 acres would be graded as part of the project and the remaining 206 acres would be preservation areas. The Specific Plan would include 9,995 dwelling units (in a mix of low, medium, and high densities) and approximately 2,419,113 square feet of retail and office uses. The project would also provide four elementary schools, one middle school, and a fire station. The proposed project is expected to generate about 25,219 new residents and 5,821 jobs. It is anticipated that construction would begin in spring 2010. The duration of construction would depend on market conditions; full buildout would likely be completed within 20 years from construction commencement. The proposed project site is approximately 2,138 acres and contains 51.87 acres of waters of the United States. The project, as proposed, would result in direct impacts to approximately 37.74 acres of waters of the United States. These acreages do not include indirect impacts from the proposed action or impacts anticipated to result from offsite infrastructure that may be determined to be required as part of the project through the Environmental Impact Statement (EIS) process.
