Few civic projects offer to bring new energy to Tampa’s downtown-area neighborhoods like the city’s plan to replace the North Boulevard Homes and Mary Bethune public housing complexes. These monuments to blight are aging symbols of all that’s wrong with warehousing poor people in dehumanizing conditions. The city has a chance to provide thousands of residents a safer, healthier and dignified living environment. And it could rebuild a riverfront community in the process. The city is working with the Tampa Housing Authority to solicit development proposals to remake 120 acres in West Tampa, north of downtown and west of the Hillsborough River. The goal is to find a developer to plan and oversee the rebuilding of the entire tract, which includes the two public housing complexes, Riverfront Park, a city truck yard and four public schools.
