How can someone find out what a property's full risk rate will be?

Of the many factors that determine the full risk rate of a structure, the single most important is the elevation of the structure in relation to the Base Flood Elevation (BFE). A community's Flood Insurance Rate Map (FIRM) indicates the area of the community that has a 1% or greater annual chance of flooding. That area is called the Special Flood Hazard Area, or high-risk zone. Put another way, the BFE is the elevation where there is a 1% or greater annual chance of flooding. For a property in the high-risk zone, you need to know the elevation of the structure in relation to the BFE. Generally, the higher the elevation above the BFE, the lower the flood risk. The information is shown on an Elevation Certificate, which is a form completed and signed by a licensed engineer or surveyor. So to determine the premium for a property in a high-risk zone, you first need an elevation certificate. Then, an insurance agent can calculate the premium based on the amount of coverage desired.
