Does the County have a map that shows floodplain?
FEMA (Federal Emergency Management Agency) maps delineating flood hazard areas can be viewed or purchased at the FEMA map center. The Permit Centers also has copies of these maps available. In addition, Henrico County has a floodplain layer in our GIS system showing the approximate limits of floodplains. Many lending and insurance institutions require a homeowner to submit an elevation certificate showing the FEMA Floodplain elevation. Often, this will require contacting a professional engineer or a certified land surveyor.
