Duffield Associates was contracted by the developer of this 81 acre mixed-use project to provide “out of the box” thinking to meet their goals of a sustainable neighborhood…specifically, to provide for protection of the on-site natural areas and waterways, use of green technologies for stormwater management and creation of a pedestrian friendly, live-work-play, neighborhood.

Duffield Associates’ engineers, geologists and scientists assimilated representatives of the town, county and state regulators as well as interested neighbors and the project developer as part of the overall design team in order to develop a design that all will be proud of. In addition to green roofs, the project intends to deemphasize conventional stormwater management practices (e.g., curbs, inlets and piping to a stormwater management basin) and make use of green technologies (e.g., porous pavement, rain gardens, bio-retention facility, grass-lined swales, etc.) for the management of stormwater flows. Additionally, it is a project goal to rehabilitate an approximate 20-acre area by stabilizing an impacted stream and restoring wetlands hydrology in order to enhance a forested wetlands and to “drown out” exotic invasive species. Creating connecting trails to the nearby library, elementary and middle schools will provide for a natural classroom opportunity.

The trails will connect with the Woodlands Perryville sidewalk network to encourage a “walking” and physically fit community. Roadways will be constructed with traffic calming devices throughout in consideration of the safety of the walking pedestrian. Parking Garages will be constructed in order to minimize surface parking and maximize open space. Pick-up points for shuttling to the nearby train station are also intended in order to encourage the use of mass transportation.

In addition to the green technology stormwater management practices discussed above, below grade retention systems to encourage infiltration may be utilized in parking and green, common space areas. The goal is to encourage recharge of the groundwater aquifer and decrease the volume of direct stormwater discharge into Mill Creek. Combined with the referenced Habitat Restoration Area these green technology stormwater management practices will also assist in the reduction of suspended sediments and nutrients into the Chesapeake Bay, our Nation’s largest estuary.
