Note: The activities described above are part of a demolition and site-preparation project covering a total 12.5-acre project site, with only approximately 3 acres taking place within the Commission’s jurisdiction. The applicants are the project proponents for the Peninsula Crossing project, a proposed biotechnology and office project for which a future BCDC major permit application is anticipated. The Peninsula Crossing project has received local discretionary approvals, including certification of an Environmental Impact Report pursuant to the California Environmental Quality Act, and is currently undergoing permitting with the Regional Water Quality Control Board and the California Department of Fish and Wildlife for proposed work along Easton Creek.

As part of the Peninsula Crossing project, the applicants plan to raise site elevations to account for potential sea level rise impacts, which will require time for the site to settle before construction could begin. The applicants are seeking authorization for demolition and site preparation activities in advance of the major permit application in order to reduce the overall amount of time between future permit approvals (if received) and completion of the project, including a number of public access improvements. The work associated with Application No. M2024.005.00 will result in the demolition of all existing site features, excavations at the sites of the buildings proposed in the Peninsula Crossing project, and the placement of lightweight fill and imported soils to raise site elevations. It will also create an expanded public access area adjacent to and replacing a portion of an existing Bay Trail segment. If a permit for this work is issued prior to Commission’s consideration of a major permit for the Peninsula Crossing project, it would not preclude the Commission’s ability to seek changes to, condition, or deny the future major permit application, including with respect to required maximum feasible public access, associated with the project.
