"About twelve years ago, I started the Codes Study to analyze cities, towns, and counties taking proactive steps toward zoning to encourage livable places. And by livable, I mean mixed-use, economically vibrant, convivial, walkable, bikeable, and transit-friendly. Many places are using form-based codes to encourage livability, in jurisdictions covering over 45 million people worldwide."

"Such code responds to today’s market pressures of families and corporations alike wanting to dwell in walkable urban places. It saves critical infrastructure dollars because of building in more compact forms. It can let us preserve more wilderness and productive farm and range lands with less sprawling development. It encourages wellness by making it easier to connect with others, instead of isolating us in single-use pods. It reinjects nature into cities in keeping with the character of its surroundings."

Hazel Borys gives us an update on the latest Codes Study, and points out recent zoning and subdivision trends including lean codes, unified codes, codes with no parking requirements, and codes that are cash cows.
