A few overlapping phenomena quickly became clear during the early days of COVID: a need to remain physically distanced from others outside our immediate household; a need for more outdoor space close to home in every part of every community to access and enjoy; a need for… Read More

Reducing VMT, Encouraging Walk Trips, and Facilitating Efficient Trip Chains through Polycentric Development

As the antidote to sprawling suburbs, compact centers can encourage all the things that sprawl discourages: public health, environmental sustainability, social cohesion, and economic diversity.
