Transit town is a new PURL initiative intended to help Phoenix visualize the future possibilities of development around the Light Rail corridor. We are investigating the redevelopment potential of areas served by Phoenix’s Light Rail Transit system. The project is an investigation of the possibilities of accommodating 30% of Phoenix’s projected 2020 population in walkable, transit serviced neighborhoods. To make this assessment, we are mapping the areas around the light rail, investigating retrofitting potential, and developing a taxonomy of development types appropriate for different contexts and scales. This is both an urban design study, as well as an analysis of the planning, policy and regulatory requirements needed for successful accommodation of 30% of Phoenix’s future population. We are investigating the needs of “complete” neighborhoods that are open to people of all ages and income levels. This project is in progress.
