Weather-related flooding is already the most common and costly natural disaster across the United States. Fairfax County continues its efforts to mitigate flooding problems for residents through the latest Floodplain Management Plan (FMP). The current plan, recently released by the DPWES Stormwater Management Program, provides an annual update on the implementation of flood mitigation actions and is a key requirement for the County’s participation in FEMA’s Community Rating System (CRS).

The Department of Public Works and Environmental Services in Fairfax County in collaboration with Operation Stream Shield crew from The Lamb Center rolled up their sleeves and dove into a spring cleaning mission. With the guidance of DPWES’ talented landscape architects, Suzie Foster and Sarah Roth, from the Stormwater Management Division, we focused on giving our native plants some much-needed TLC after the winter. Our efforts included deadheading spent blooms to make way for new growth and planting "live sticks" to encourage more greenery around our tranquil pond area. It's all about creating a thriving habitat for our local wildlife and a serene space for everyone to enjoy.
