POLICY

•ALLOWABLE BAY FILL •Public Benefit vs. Detriment – Water-oriented uses

•Meets the ‘recreation’ and ‘ public assembly’ criteria •No alternative upland location •Minimum fill through design approach•Minimal negative effect on Bay resources •Designed for “end of century” SLR projections (66”) + 100-year

storm event (~30”)

I

POLICY

•MAXIMUM FEASIBLE PUBLIC ACCESS •Creates new public access to the shoreline and over the water •Connects to existing public access networks •Synergizes with long-term public access developments
