We provide elevation surveys throughout the state. An elevation survey is needed in order to prepare an Elevation Certificate and/or an eLOMA or LOMA. An elevation survey determines the elevation of a building’s lowest floor, first floor, lowest adjacent grade (LAG) and highest adjacent grade (HAG), as well as an attached garage. These elevations are based on a known elevation benchmark, and are referenced to the North American Vertical Datum of 1988 (NAVD88).
An Elevation Certificate is the result of an elevation survey. This document is needed to determine a structure’s current risk and flood insurance premium. If the elevation survey reveals the LAG to be above the Base Flood Elevation (BFE), it is possible for that building to be removed from the Special Flood Hazard Area (SFHA). This is accomplished through a Letter of Map Ammedment (LOMA or eLOMA).
