The Brookfield Park Wet Pond construction project in Fairfax County was completed on November 14, 2014, aiming to rebuild a failing wet pond for improved stormwater management and water quality. Key improvements include a new riser structure, wetland forebay, and enhanced landscaping, resulting in significant reductions in nitrogen, phosphorus, and sediment runoff. The project was a collaborative effort involving multiple divisions and contractors to restore the pond and surrounding infrastructure.
