Frequently asked questions about Maryland

Can a property in Maryland qualify for a FEMA LOMA?

Yes, many Maryland properties qualify when the structure or parcel sits on natural high ground above the Base Flood Elevation. Urban corridor LOMA files often involve older parcels mapped inside generalized Zone A areas. A specialist review can confirm whether the property matches the LOMA pattern before you order new survey work.

When is a LOMR-F the right path in Maryland?

A LOMR-F applies when earthen fill created the elevation difference. LOMR-F activity appears in coastal waterfront developments on engineered fill. If fill was used, packaging the file as a LOMA usually creates delay.

Who can prepare an Elevation Certificate in Maryland?

A Maryland-licensed Professional Land Surveyor or Property Line Surveyor must prepare elevation documents. FloodMapReview.com can review an existing Elevation Certificate or connect you with a qualified professional if new survey work is needed.

Which Maryland counties see the most LOMA and LOMR-F activity?

Activity is concentrated in Baltimore County, Montgomery County, Anne Arundel County, driven by chesapeake bay flooding and urban stormwater.

Does a LOMA in Maryland automatically remove flood insurance?

Not automatically. A LOMA can change the federal mandatory-purchase requirement, but Maryland lenders and insurance carriers still make underwriting decisions. A Maryland homeowner may still choose to keep voluntary coverage.

How long does a Maryland LOMA typically take?

Timing depends on document readiness and whether the case qualifies for the faster professional-submitted eLOMA route. Most Maryland files move faster when the Elevation Certificate and FEMA correspondence are gathered before submission.
