This half-mile long bayfront roadway improvement project involved resolution of several complex issues, including public access, landfill capping, roadway engineering, agency approvals, and creation of shellfish habitat as mitigation. Callander Associates' responsibilities included master planning the public access improvements, processing permits through the San Francisco Bay Conservation and Development Commission and the U.S. Army Corps of Engineers, and preparation of construction documents. Specification of planting and irrigation improvements to be installed on top of a clay cap leachate barrier was among many challenges unique to the project. A specially-designed sloping substrate for shellfish habitat was developed by Callander Associates' staff in conjunction with the California Fish and Game Department. As installation was completed in 1992, the design intent became apparent: a bayfront promenade linking seating areas and providing for substantially more public use and enjoyment than before.
