NFIP Policy Index
Encroachments are activities or construction within the floodway including fill, new construction, substantial improvements, and other development. These activities are prohibited within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses that the proposed encroachment would not result in any increase in flood levels.
The community is responsible to review and maintain record of the documentation demonstrating that any permitted floodway encroachment meets NFIP requirements. A "no-rise certification" for floodways may be used to document the analyses.
