The effort to change a former military aircraft taxiway along San Francisco Bay into wetlands has gotten a setback after the City Council balked at setting aside money to create a master plan for the $14 million project. Known as “DePave,” the park is proposed for the former Alameda Naval Air Station. It’s expected to feature walking paths and overlooks, where people can watch birds and harbor seals resting on floating platforms. Last year, the city’s Recreation and Parks Commission unanimously endorsed a draft “vision plan” for the future 16-acre park. The council also has broadly supported it, at least vocally.
