12 Redevelopment is a Key Strategy Redevelopment of Greyfields Nelson estimated 2.8 million acres were ripe for redevelopment Enough to accommodate a large share of new housing units over the next 20 years The question How much will they actually accommodate? The answer Depends on how effective we are in supporting infill development 12

18 Atlantic Station - Outcomes Original EPA estimate = VMT 50% less than comparable greenfield sites Monitoring report surveys Regional Average = 32.4 miles/day per household Atlantic Station = 8.6 miles/day per households 19% of trips made to/from Atlantic Station are by transit, and (ARC 2008) Roughly 40% of all trips stay on site 80% of those are walk trips 18
