The Colonial Town Park Development in Seminole County, Florida, is a 175-acre campus that includes more than one million square feet of office space, a 534-unit multi-family development, and more than 60 acres of open green areas. As both a Development of Regional Impact (DRI) and a Planned Urban Development (PUD), we helped guide the permitting through a series of state-mandated reviews to determine pollution creation/alleviation levels, vehicle and pedestrian traffic, energy-grid consumption, and the prospective resident estimates.
