Fairfax County's Department of Public Works and Environmental Services (DPWES) generates technical reports that document the results of some of the monitoring, research, and analyses work we do to serve county residents. These reports are public information and are shared here for people to read and use.

DPWES protects people and our environment by building and maintaining public infrastructure.  Our work to create and preserve a sustainable community has been recognized across the country. DPWES staff members work together with universities, scientists and other partners like the United States Geological Survey to create and share reports, research, technical guides, and yearly update reports. 

Stormwater Management

Workers in Stormwater Management check the health of streams, rivers, and urban forests in the county. They make sure the county follows local, state, and federal rules. They take care of systems that clean and control stormwater, work to reduce flooding, and improve the urban forest and open spaces so that nature stays healthy and residents can enjoy a good quality of life.
