The Curtain Wall Repairs and Stormwater Improvements at B Street Pier Project is a structural rehabilitation and stormwater infrastructure upgrade for the Port of San Diego’s B Street Pier. The project consists of two phases; curtain wall repairs and backfilling at B Street Pier and stormwater infrastructure improvements at B Street Pier that will be constructed in sequence.
The phase 1 curtain wall repairs and backfilling contract work will upgrade the mole pier’s structural and seismic capacity with new sheet pile and pavement, modify soil characteristics using Deep Soil Mixing (DSM) techniques and replace select portions of existing utilities as well as produce updated utility bulkhead crossings including the pier’s drainage system outfalls.
The phase 2 stormwater infrastructure improvements contract work will introduce permanent Best Management Practices (BMPs) to the B Street Pier drainage system to improve water quality of storm water runoff from B Street Pier into the San Diego Bay. Improvements will be in conformance with the Port’s BMP Design Manual and will consist of runoff interception structural treatment devices and supporting drainage system modifications intended to capture and treat within a tributary range of 9% to 60% of the pier’s surface area.
