Can a LOMA Remove a Property From a Floodplain?

A property owner may ask, “can LOMA remove floodplain status?” The practical answer is yes, in some situations - but a LOMA does not physically remove land from a floodplain or change how water moves across a site. It is FEMA’s determination that a specific structure or legally defined parcel was incorrectly shown within the Special Flood Hazard Area on the current Flood Insurance Rate Map.

That distinction matters in Sarasota and throughout coastal Florida. A FEMA flood map is a broad mapping tool, while a survey measures the actual ground elevation at a specific property. When accurate elevation data shows that the lowest adjacent grade is at or above the Base Flood Elevation, a property owner may have grounds to request a Letter of Map Amendment, commonly called a LOMA.

What a LOMA Can Remove From a Floodplain Map

A LOMA can remove a structure, a parcel, or both from the mapped Special Flood Hazard Area, also called the SFHA. The SFHA is generally identified on FEMA maps by zones beginning with A or V. Properties in these zones may be subject to a lender’s federal flood-insurance requirement when the building is financed through a federally regulated lender.

FEMA issues a LOMA when the property’s natural ground elevation supports the conclusion that it is outside the area subject to the mapped base flood. The key word is natural. A standard LOMA is intended for property that is above the Base Flood Elevation without the placement of fill.

The result is often significant. If FEMA grants the LOMA and the structure is removed from the SFHA, the federal requirement for flood insurance generally no longer applies. A lender makes the final determination for its loan, however, so owners should provide the approved LOMA to the lender and insurance agent rather than assuming a policy can be canceled immediately.

A LOMA does not erase the possibility of flooding. Heavy rainfall, drainage limitations, storm surge, and changing coastal conditions can affect properties outside the SFHA. It also does not automatically change local construction requirements, community floodplain rules, or private insurance decisions.

When Can a LOMA Remove Floodplain Status?

A LOMA may be appropriate when FEMA’s mapped boundary does not match the property’s surveyed elevations. This can happen because FEMA maps are prepared using available topographic information and are not a site-specific elevation determination for every lot or building.

For an individual structure, FEMA generally considers whether the lowest adjacent grade - the lowest ground touching the building - is at or above the Base Flood Elevation. For a parcel request, the relevant question is whether the lowest ground elevation on the entire legally described parcel is at or above that elevation. The parcel standard is broader and can be more difficult to meet, particularly on larger or uneven sites.

A home can qualify for a LOMA even when neighboring homes do not. A few inches of elevation difference, the location of the mapped flood boundary, or a change in ground elevation across a subdivision can produce different results from one lot to the next. That is why a site-specific survey is more useful than relying on a neighborhood’s general flood-zone reputation.

A LOMA is not the right path when a building pad or lot was raised with fill to reach the required elevation. In that situation, a Letter of Map Revision Based on Fill, or LOMR-F, may be the appropriate FEMA request. The documentation and eligibility requirements differ, so identifying whether the ground is natural or filled is an early and necessary step.

The Survey Evidence FEMA Needs

A successful LOMA application depends on accurate, defensible information. FEMA needs enough documentation to compare the property’s measured elevations with the applicable Base Flood Elevation and the current map panel.

For many residential requests, a licensed land surveyor prepares an Elevation Certificate or other FEMA-required elevation documentation. The survey work establishes the building location, relevant ground elevations, flood-zone information, and vertical datum used for the comparison. Using the correct datum is critical. Elevations cannot be evaluated reliably if a survey uses a different reference system than FEMA’s published flood data without an appropriate conversion.

The application may also require the recorded deed or legal description, tax parcel information, photographs, plat information, and other supporting materials. FEMA’s current application process and form requirements can vary based on the type of request. A complete submittal reduces delays caused by missing legal descriptions, unclear property identification, or elevations that do not support the requested determination.

An Elevation Certificate by itself does not grant a LOMA. It is technical evidence that may support the application. FEMA must review the submitted information and issue the official determination before the map status changes for the identified property or structure.

Why field work matters

Online flood maps are useful for an initial review, but they cannot establish whether a particular foundation, finished lot, or parcel boundary is above the Base Flood Elevation. Map lines are not property lines. A boundary survey, recorded plat, or legal description may be needed to confirm that the surveyed area is the same property identified in the FEMA request.

This is especially relevant for homes near a flood-zone boundary. A building may sit outside the SFHA while part of the lot extends into it. Conversely, the mapped boundary may cross a structure even though surveyed grades show the structure qualifies for removal. The requested scope should match the owner’s objective: removing a building from the SFHA is different from seeking removal of an entire parcel.

What Changes After FEMA Issues a LOMA

Once FEMA approves a LOMA, the determination applies to the structure or parcel specifically identified in the letter. It does not revise the flood designation for every nearby property. Owners should retain the letter with their closing documents, survey records, insurance information, and any future permit documentation.

For a mortgaged structure removed from the SFHA, the lender may discontinue the mandatory flood-insurance requirement. The lender is not required to do so automatically, and it may still require coverage as a condition of the loan. Flood insurance can also remain a sensible risk-management choice, particularly in Florida, where flooding can occur outside FEMA’s mapped high-risk zones.

The insurance effect depends on the policy, lender, carrier, and property’s continuing risk profile. An owner may be eligible for different coverage options or premiums after a LOMA, but should discuss the approved determination with a qualified insurance professional before changing coverage. Do not allow a policy to lapse simply because an application has been submitted or a survey appears favorable.

A LOMA also does not override local regulations. A municipality or county may still apply floodplain-management standards, drainage rules, elevation requirements, or permit conditions based on its own adopted ordinances. For additions, substantial improvements, new construction, or redevelopment, verify project requirements with the local permitting authority early in the planning process.

A Practical Way to Evaluate Your Property

Start by confirming the property’s current FEMA map designation and locating the structure in relation to the SFHA boundary. Then obtain a professional review of the site elevations and available property records. If the ground elevations appear to meet FEMA’s criteria, a surveyor can advise whether a LOMA, a LOMR-F, or no map amendment is the appropriate route.

For a purchase or refinance, begin this review before the final insurance and lending decisions are due. A LOMA application can affect cost, timing, and negotiations, but it should not be treated as guaranteed until FEMA issues its written determination. Buyers should also understand whether the request covers only the house, the entire parcel, or neither.

CDB Surveying helps property owners and real estate professionals assemble the precise elevation and property documentation needed to evaluate a FEMA map amendment request. The goal is not simply to produce a form. It is to give the owner, lender, insurer, or buyer reliable information about the property’s mapped flood status.

If your property is near a FEMA flood-zone line, the most useful next step is a site-specific review before making insurance, lending, or construction decisions. Clear survey evidence can show whether a map amendment is justified and, just as importantly, when the existing designation should be treated as the controlling condition.
