In the aftermath of Harvey, a great deal of attention is being paid to flood-prone areas of the country – specifically, the FEMA maps that show a location’s annual flood risk. These maps are important – beyond showing flooding risk, they determine whether federally-funded mortgages will require flood insurance or not.
It’s also useful to know if you’re building a chemical plant that might explode if it gets flooded.
(Spoiler alert: pretty much anywhere near a river or the coast is at significant risk of flooding.)
If you’re interested in knowing whether your house is in a flood zone (and you should be), FEMA has an online tool for viewing the flood map of an address here. You can also download a layer for viewing on google earth here.
