Watershed Planning and Management

Watershed Planning

Versar is the preeminent watershed-planning firm in the mid-Atlantic region. We have carried out watershed plans for Anne Arundel, Baltimore, Fairfax, Frederick, Howard, and Montgomery Counties in Maryland; for the Fairfax County Park Authority in Virginia; the Columbia Association in Maryland; Fort Lee, Virginia; and the Baltimore and Philadelphia Districts of USACE. Versar has been deeply involved in the evolution of watershed planning since 1993, including developing watershed implementation plans to meet impervious cover and TMDL targets in MS4 permits. Our expertise includes the latest environment site design, geo database tools, modeling, and ecological science founded in our 20 years supporting the Maryland Biological Stream Survey.
