Flood mapping is a system built on engineering, policy, and public record — most of it accessible to any property owner willing to look. The problem is that almost nobody explains it in plain language. This library does. Start with what you need to know, go as deep as you want.
Flood risk involves your zone, your insurance, your property's history, and your options. Each affects the others. Here's how to orient yourself depending on where you're starting from.
Start with Flood Zones, then Flood Insurance
Start with Flood Zones, then Elevation Certificates
Start with LOMAs & LOMRs, then FIS & FIRM
Start with Substantial Improvement Rules
Start with Risk Rating 2.0 Guide

Every FEMA flood zone designation — AE, VE, AO, AH, A, X Shaded, X Unshaded, Floodway — explained in plain language. What each means for insurance, mortgages, and development.

Read FAQ →Everything here is general — flood zones as a concept, insurance as a system, LOMAs as a process. Your property has a specific zone with a specific history. Your insurance has specific gaps. Your LOMA eligibility is a specific yes or no based on specific data.
A Flood Risk Intelligence™ report closes that gap — pulling the records, interpreting the data, and giving you the property-specific analysis that turns general knowledge into a decision you can actually make.
