Check FEMA flood maps before buying property near creeks or the lake in Rockwall County

FEMA maintains official Flood Insurance Rate Maps (FIRMs) for Rockwall County. Properties in a Special Flood Hazard Area (Zone A or AE) have a 1% or greater chance of flooding each year. If you have a federally backed mortgage on such a property, your lender will require flood insurance.

Rockwall County's official website has a dedicated flood information page. You can search any address at the FEMA Flood Map Service Center (msc.fema.gov) to see what flood zone applies. Properties outside a mapped flood zone can flood too, and flood insurance is available to anyone, not only those who are required to buy it. Look at the maps before making an offer on any home near the lake shoreline, the East Fork Trinity River, or local creeks.
