Document Description
The proposed project consists of buildout of the proposed Southline Specific Plan (Specific Plan). The EIR will provide a program-level analysis of the potential effects on the environment that could occur from implementation of the proposed project. The EIR will also provide a project-level analysis of the initial development phase of the Specific Plan (Phase 1), which is a component of the proposed project. The EIR will be used to provide CEQA clearance for adoption of the Specific Plan and entitlement of Phase 1. Following is a brief description of the proposed project, including Phase 1. The proposed project includes a new office/research and development (R&D) campus with a maximum anticipated building area of up to 2.8 million square feet. The proposed project would demolish all existing on-site uses and construct seven office buildings, an amenities building, underground parking throughout the site, a parking structure, a new east-west connection road, and approximately 369,000 square feet of open space. Building heights would range from four to seven stories. Development associated with the proposed project would be implemented under the proposed Specific Plan, which would establish new land use development standards and design guidelines for the project site. A phased development process with three phases is anticipated. Phase 1 would include construction of the new east-west connection road described above and the following development south of the new road: three buildings totaling approximately 972,700 square feet of office, amenity, and retail space; approximately 2,000 parking spaces in a combination of below-grade parking and a temporary surface lot; and landscaping and open space amenities. Phase 1 would require approval of a detailed Precise Plan; future development phases would be approved as subsequent precise plans.
