What to do
1. Check the property’s zone in the Property Information Map
Search for the address. Select the “Environmental Information” tab.
Scroll down to “Flooding: FEMA FIRM Flood Hazards (Coastal).”
Check if the property is considered to be in a Special Flood Hazard Area.
Ignore the “Flooding: 100-Year Storm Flood Risk Zone (Stormwater)” section. The ordinance does not apply to properties located only in the stormwater flood risk zone.
2. Hire a licensed design professional to fill out the Flood Hazard Zone Protection Checklist
3. Submit the checklist and other documents when you apply for a building permit
After plan review
