Manassas Regional Stormwater Management
Manassas, Virginia
Dewberry prepared feasibility studies for 19 possible regional stormwater management facilities at various locations in the City of Manassas. Dewberry evaluated the feasibility of each pond site for detention benefits, water quality controls, cost, land acquisition costs and environmental permitting. To ensure against fatal flaws with the environmental permitting, detailed wetlands evaluations were conducted along with early permit coordination with the regulatory agencies. |

Franconia-Springfield Transportation Center and Metrorail Line
Springfield, Virginia
Dewberry designed the extension of the Metro system into Springfield. The project site included a significant amount of wetlands, and two large floodplains within a 1,170-acre highly developed watershed. To meet stormwater management detention requirements, and the need to provide mitigation for wetlands affected by the transportation center, Dewberry designed four extended detention dry ponds to provide regional stormwater management within 18 acres of created wetlands. |
