Improvement Opportunities
The plans identify areas of opportunity for implementing both structural and non-structural improvement projects such as stream restorations, stormwater facility retrofits, community education and stewardship, streamside buffer enhancements and installation of green stormwater infrastructure (GSI). Proposed projects in the plans have recommended priorities. These lists should not be interpreted as specific implementation schedules or a guarantee that the project will be implemented through the planned Capital Improvement Program (CIP). A full list of active or completed Stormwater projects is available online on at Stormwater Improvement Projects or through Jade (Fairfax County's Comprehensive Mapping Application).
