Capital Improvement Program
The District primarily accomplishes structural flood hazard mitigation through its five-year Capital Improvement Program (CIP) which is the revolving funding plan for accomplishing capital projects.
-
Small Project Assistance Program
The District has recognized that, particularly in urban areas, localized flooding hazards exist where large structural solutions would be impractical. The Small Project Assistance Program provides a mechanism for the District to commit funding, on a limited basis, to advancing localized solutions in these situations.
-
Floodprone Property Assistance Program
Similar to the Small Project Assistance Program, the Floodprone Property Assistance Program provides a tool to mitigate flood hazards where structural solutions are impractical.
