All our work with insurance companies is focused on FEMA floodplains — with the goal of reducing insurance costs, removing flood zone designations, or mitigating flood zone exposure for your policyholders.
McMahon LaRue Associates works directly with insurance companies and their clients to evaluate FEMA flood zone designations and determine whether properties can be removed or reclassified. Our licensed engineers and surveyors have decades of experience with FEMA's Letter of Map Amendment (LOMA) and Letter of Map Revision (LOMR) processes.
When a property has been incorrectly mapped into a Special Flood Hazard Area — or when engineered drainage improvements have reduced actual flood risk — we prepare the technical documentation needed to get the designation changed. The result is reduced or eliminated flood insurance requirements for your policyholder.
FEMA-compliant elevation certificates prepared by licensed surveyors for flood insurance rating and zone challenges.
Documentation to remove a structure or lot from a Special Flood Hazard Area when it has been incorrectly mapped.
Engineering support for formal map revisions following drainage improvements or new hydrologic analysis.
Field survey and HEC-RAS hydraulic modeling to establish accurate base flood elevations for disputed properties.
Rapid assessments of flood risk and potential for zone removal before a property sale closes.
Our Professional Land Surveyors prepare elevation certificates that meet FEMA standards — required for all LOMA submissions and flood insurance policy ratings.
We perform advanced hydraulic modeling to establish or challenge base flood elevations — the technical foundation for any successful flood zone map revision.
Three decades of projects across Monroe, Wayne, Ontario, and Genesee counties means we know the local flood maps, drainage systems, and FEMA regional office processes.
Call or email us to discuss the property. We'll let you know quickly whether a LOMA or LOMR is feasible and what the process looks like.
