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 new development would include commercial office/R&D buildings, a four-story supportive amenities building (Building 2) totaling approximately 88,200 square feet, approximately 3,064 underground parking spaces at various locations throughout the Specific Plan area, a nine-story parking structure with approximately 2,705 spaces (Parking Structure C), a new east–west connection road (Southline Avenue; provisionally named for the purpose of the Specific Plan and California Environmental Quality Act [CEQA] review), supportive utilities and related infrastructure, and up to 341,800 square feet (7.8 acres), of open space. Commercial building heights would range from four to seven stories, subject to maximum building height limits in accordance with Federal Aviation Administration (FAA) and Airport Land Use Compatibility Plan (ALUCP) requirements. 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 is anticipated. Phase 1 would include construction of the new Southline Avenue east–west connection road and the following development, generally located south of the new road: two new office buildings (Buildings 1 and 7), with a total building area of up to approximately 612,715 square feet; the four-story, approximately 88,200-square foot amenities building (Building 2); landscaping and open space amenities; and approximately up to 2,664 parking spaces in a combination of below-grade parking and the eastern portion of the nine-story parking structure located north of the new Southline Avenue (Parking Structure C). Phase 1 would require approval of a detailed Precise Plan; future development phases would be approved as subsequent precise plans.
