A number of indices measure walkability, affordability, and environmental performance, including CNT's H+T Index, Walkscore, and IMI's Walkability Index. But they may not be measuring livability quite yet. Hazel Borys invites you to add to the Collaborative Google Maps that currently track Form-Based Codes and Traditional Neighborhood Developments. Borys says:
"At the macro level, a livable project is one that embodies the CNU Charter. However, there are few metrics associated with the Charter. Many projects can look great from satellite view, as seen on the following maps: Eastern US | Western US | Canada. Turn on satellite view, zoom in, and analyze. Still, when walking down these streets, the neighborhoods have various levels of authenticity, immersiveness, and livability."
"Similarly, the SmartCode is a starting point for urban metrics, with significant changes to the numbers based on local character. On top of that discussion, you could layer on environmental impacts of TNDs. They may provide great examples of urban form, but have dismal H+T Index performance. Form-based codes (FBCs) remove barriers to entry for walkable infill and redevelopment that can deliver better housing and transportation affordability. Collaborative Google Maps are part of the Code Study: SmartCodes Adopted | SmartCodes in Progress | Other Form-Based Codes."
