What is a FEMA Map Study? A FEMA map study is a study used to determine how high the water will rise in a particular water course.  In the study, storm surge levels are determined for the 100-year storm and the areas within the storm surge are considered floodplains.  This information is then used to determine high risk, flood areas and whether or not flood insurance will be required for a particular property.

What does a FEMA Map Study entail?

We use a program called HEC-RAS, which allows us to simulate a storm and view the floodplain boundaries.  The program generates a 2-D cross section of a tributary and the flood levels associated to that area of the tributary.  We can then delineate the floodplain boundaries on a map.

Why should you contact D.L. Howell & Associates for FEMA Map Study services?

D. L. Howell and Associates has been working with FEMA doing floodplain analysis studies for more than ten years, which makes us very familiar with the work required to get these analyses approved.
