CityBldr launches Public demo using zoning data from 100 U.S. cities to map public land and housing potential

Bellevue-based CityBldr has launched a free demo site, Public, that uses its five-year-built zoning and land database covering 100 U.S. cities to map underutilized publicly owned parcels and estimate how many people each could house under current zoning. The company plans a sponsorship program for corporations to fund affordable-housing nonprofits in exchange for full access to the complete dataset.
