How will the new levee protect the city from wave run-up and future sea level rise?

The levee design elevation has accounted for wave run-up, and the outer walls at the access points (AP) adjacent to the bay will provide protection from wave run-up and are designed with a concrete floodwall on the bay side of the AP, to be sufficiently long to break the waves before the water finds its way through the AP openings. Elevations along the new trail (bottom of the openings) are generally at least four feet above the current 100-year water level in San Francisco Bay, allowing for future sea level rise. The top of the walls are designed for the wave run-up associated with high winds and high tide levels. Flood barriers are also located at three different locations along the levee:  (1) at the Egress bridge (near Rock Harbor Lane); (2) at Baffin Bridge; and (3) on the levee pedway south of San Mateo Bridge.
