Common reasons LOMA requests fail
A guide to the mistakes and weak assumptions that often derail LOMA-related files.
Many LOMA requests fail because the property was really a fill case, the evidence package was incomplete, or the file tried to answer the wrong property question.

Frequently asked questions
What is the single biggest cause of failure?
Filing the wrong request type is the most common root cause we see. A property that actually sits on fill gets routed as a LOMA, or a lot case gets filed as a structure case, and the file stalls. A short triage step before submission prevents most of these losses.
Can a denied LOMA be re-submitted?
Yes. FEMA's denial letter usually identifies what was missing or inconsistent, and the file can be corrected and resubmitted. Depending on the issue, the resubmission may need a new Elevation Certificate, additional survey work, or a change of request type. Treating the denial as diagnostic rather than final is the right mindset.
What role does the Elevation Certificate play in denials?
Elevation Certificates are the single most scrutinized document in a LOMA file. Errors in the datum, building diagram, or lowest adjacent grade can sink an otherwise strong case. A quick review by an experienced surveyor or engineer before submission catches most of these issues.
Does missing the right scope (structure vs lot) cause failure?
Yes. A structure LOMA and a lot LOMA answer different questions and use different elevation references, so filing at the wrong scope can lead to a technical denial even when the ground is actually high. Confirming what the requester actually needs, usually driven by lender or insurance context, avoids this mistake.
Can an older FIRM panel cause problems?
Older panels sometimes lack the precision of modern mapping, which can make the zone boundary harder to interpret. A LOMA request tied to an older panel may need extra supporting data to show the property's actual elevation clearly. Checking whether a newer FIRM is effective or pending is part of the intake.
What if the lot was partially flooded during a storm — does that disqualify a LOMA?
Not on its own. A LOMA decision is based on mapped base flood elevations and documented ground elevations, not on whether a specific storm caused water on the lot. Historic flooding can complicate the discussion with lenders or insurers, but it does not automatically block the determination.
