An article in PD&R Edge highlights progress on the National Zoning Atlas, an effort to consolidate nationwide zoning data into one GIS database to let researchers analyze and compare zoning policies and their effects. “The purpose of the atlas is to offer insight into zoning’s effects and democratize land use decisionmaking through comprehensive, digitized, and user-friendly zoning information.”

The creators of the Zoning Atlas say “the decentralization of zoning laws has hindered the identification of problems arising from land use regulations.” The effort is already underway in 21 states, and almost complete in New Hampshire. 

“An ongoing challenge that the atlas can help address is the obfuscating effects of complex and competing land use interests to reform.” As the article explains, “Aggregating this information makes the scale of statewide challenges more readily apparent and could bring stakeholders on board to address the collective action problems that intricate zoning systems pose.”
