Description from store
FloodScope is a powerful Chrome extension that seamlessly integrates FEMA flood zone data directly into popular real estate websites including HAR.com, Homes.com, and Realtor.com. With a simple installation, users can instantly access critical flood risk information while browsing properties, eliminating the need to switch between multiple sites or perform separate searches.
Key Features
Multi-Platform Support: Works natively on HAR.com, Homes.com, and Realtor.com property listings
Instant Flood Zone Assessment: View a property's FEMA flood zone designation and risk level directly within property listings
Interactive Maps: Color-coded flood zone maps embedded in property pages showing:
High-risk A Zones (blue)
Coastal V Zones (red)
Low-risk X Zones (green)
Floodways (dark blue)
0.2% Annual Chance Flood Areas (orange)
Comprehensive Risk Information: Clear explanations of each flood zone type, insurance requirements, and potential risks
FEMA Integration: One-click access to official FEMA flood maps for any property address
Address Search: Check flood zones for any address, even if not currently viewing a property listing
Cached Results: Faster loading for previously checked properties
How It Works
FloodScope seamlessly integrates into supported real estate websites. When you visit a property listing, the extension:
Automatically detects and extracts the property address
Queries FEMA's National Flood Hazard Layer (NFHL) data
Displays a clean, informative flood zone panel showing:
The specific flood zone designation (A, AE, X, etc.)
Whether the property is in a Special Flood Hazard Area (SFHA)
An interactive map highlighting flood zones around the property
A detailed interpretation of what the zone means for homeowners
For HAR.com users, the extension even works when clicking properties on the map view, displaying flood information in the popup overlay.
