Title

Foster City Levee Protection Planning and Improvements Project (Capital Improvement Project - CIP 301-657)

Description

The purpose of the project is to provide flood protection in accordance with updated FEMA guidelines and regain FEMA accreditation for its existing levee system. Current FEMA guidelines require the current levee elevation along the city's levee system to be raised to protect the city from flooding associated with levee overtopping from extreme high tides or storm surges. In addition, the improved levee system will be designed to adapt to future sea level rise while maintaining public access along the levee system and protections for sensitive species. The precise design and height of the project is not yet finalized; therefore, the environmental analysis studies two scenarios at an equal level, which would have different ranges of levee elevations/floodwall heights as needed to meet FEMA freeboard requirements and protect against future sea level rise. The two scenarios are: (1) FEMA Freeboard with Sea Level Rise for the year 2050, and (2) FEMA Freeboard with Sea Level rise for the year 2100. Based on currently available data, preliminary evaluations, and city council direction, the city anticipates that the project will utilize a combination of three different levee improvement types, depending on the location along the existing levee earthen levee, and (3) conventional floodwall.
