The Bayshore Bikeway Resiliency Project (Project) will retrofit a 1.2 segment of the San Diego Bayshore Bikeway (Bikeway). The project seeks to repurpose the existing bikeway into a multi-benefit coastal resilience corridor that protects multiple vulnerable communities, a state highway, and the Bikeway itself from current and future coastal flooding while improving coastal access and adding transitional habitat areas along the bay edge. 

To accomplish these objectives, the project will develop concepts using a variety of nature-based features and adaptation strategies including a Living Levee: Elevate the Bikeway using a living levee concept and ecotone slope to increase community and ecosystem resilience to sea level rise. 

It also foresees the construction of a stormwater treatment wetland. An evaluation will be conducted on the use of a stormwater treatment system to accommodate excessive rainfall that will be increasingly difficult to manage within the disadvantaged residential community. The system may include a wet pond, treatment wetland/detention basin and pump station.

This project also includes coastal access trail enhancements which consist in adding multi-use paths alongside the Bikeway to provide connectivity and reduce conflicts between bikes and pedestrians.

The project provides for habitat enhancements measures. Hence, it will evaluate opportunities for existing tidal marsh enhancements and restoration within the context of other Project goals and objectives. For example, the Project may evaluate elevating the flood-prone bikeway on a pile-supported causeway to improve hydraulic connectivity of an existing tidal marsh (Pond 10A) – if determined to be a benefit to the tidal marsh.

Development of alternatives will be informed by stakeholder and community outreach events throughout the process. The final deliverable of this Project will be preliminary design drawings (30%) of the preferred alternative with sufficient detail to progress the Project into the next phase (CEQA, permitting, final engineering and construction). The Project will develop resilient strategies within the 1.2-mile reach will provide a proof-of-concept that could be applied along other segments of the 24-mile bikeway corridor to protect communities with similar needs.
