Trulia’s Local Info is the most user-friendly map view of FEMA flood maps. It’s also a great resource for earthquake, tornado, and other natural hazards.
The official FEMA address-based search is available at the FEMA Map Service Center, where you can create a “FIRMette”.
However, FEMA maps aren’t the only flooding hazard resource. The City of Tulsa (and possibly surrounding municipalities) has its own requirements regarding flooding.
If you’re concerned about a property in the City of Tulsa, you may contact the Customer Care Center to request a free Flood Zone Determination for any property you’re interested in. You’ll need to provide them your information (so they can deliver the report) and the subject property’s street address and legal description.
Contact information for Creek, Osage, Rogers, Tulsa, and Wagoner Counties is available at INCOG’s Floodplain Overview.
