Flood mapping for residential properties

Understand the risk around your home with FRA Flood Mapping

Flood maps are intended to incorporate the latest and most accurate information into the maps so that they better reflect the risk that communities face. Flood maps show the extent to which areas are at risk for flooding, and are used to help determine flood insurance and building requirements, but they aren’t always correct and at times they need to be updated. Flood Risk America’s unique services are specifically developed for property lending for banks and insurance agents. FRA’s services are customized for all levels and sizes of property portfolios.

We first determine whether a large development track is inside, outside, or in neighboring flood zone areas using out Flood risk analysis service. When getting a true analysis, FEMA maps may not always be accurate and up to date. Flood Risk America gives you a chance to get a better flood coverage for your property by taking advantage of our advanced Flood Re-Mapping Program.

From the date of receipt, we track and share the status changes from map revisions. FRA uses a web-based system that is staffed by nationally certified flood plain managers dedicated to provide a real-time and thorough assessment. Quality data is guaranteed, audited, and must meet a 99.9% accuracy standard.With our highly skilled engineers and flood specialists, we find alternative ways using our re-mapping services to re-rate flood insurance policies, giving this company a competitive edge.

How do we create new flood maps?

We use what is called LiDAR (Light Detection and Ranging Technology). LiDAR uses a pulsed laser to calculate an object’s variable distances from the earth surface. These light pulses are put together with the information collected by the airborne system and generate accurate 3D information about the earth surface and the target object or property in question to create an accurate model of the flood zone and map. In a LiDAR system, a laser emits light that travels to the ground and reflects off objects like buildings and trees. The reflected light energy returns to the sensor, whereby the time interval is recorded. Since the conventional methods cannot produce high-resolution digital elevation model (DEM) data, which results in low accuracy of flood simulation results, LiDAR data is what we extensively use as an alternative.

The benefits of Flood Mapping with LiDAR

The reason why Flood Risk America uses the LiDAR is because of its ability of the LiDAR systems to provide higher-resolution and centimeter-accuracy outcomes which diversifies their use in wide-ranging applications of flood studies and re-mapping abilities. LiDAR provides detailed information on the elevation of the ground surface for predicting flood inundation from rivers and coastal sources. Detailed LiDAR measurements not only offer higher resolution elevation for floodplain modeling, but they also provide a source of high-resolution surface roughness information. High resolution and high accuracy of a topographic dataset are important in predicting flood inundation and occurrence of flood disasters in the world.

Flood Risk America uses different types of LiDAR systems to accurately record the land and property in question to gather the data needed in order to precisely map the recorded information and challenge FEMA on ground elevations using this new available data.
