National Flood Insurance Program (NFIP)

The NFIP is a Federal government program that enables property owners in participating communities such as Johnson City to purchase flood insurance protection. Participation requires that the communities adopt and enforce a floodplain management ordinance to reduce flood damage risk especially for properties in the Special Flood Hazard areas or floodplain. Click here for information on how to buy or renew flood insurance, how to reduce cost, understand your risk, file a claim, etc.

If you don't have flood insurance, talk to your insurance agent or shop around. Homeowner's insurance policies do not cover damage from floods. However, because Johnson City participates in the National Flood Insurance Program, you can purchase a separate flood insurance policy, but there is a 30-day waiting period. This insurance is backed by the Federal government and is available to everyone, even for properties that have been flooded. Johnson City currently has a Class 9 Community Rating System, which provides homeowners a 5% discount on their flood insurance.

Flood Permits

Developments in the floodplain require a Flood Permit. Erecting structures in the floodway is prohibited. To determine if your property is in the City’s regulated floodplain, access the Land Development Map Viewer
