Every year hurricanes and storms hit the Roanoke Valley, posing a potential danger of rising water levels in our streams and rivers.

Most of the flooding is caused by flash flooding. Flash flooding occurs when natural and engineered drainage courses overflow, causing serious flooding in a short time. The storm water can flood buildings, yards, bridges, and streets.

Elevation Certificates

An Elevation Certificate is a document that provides information necessary to verify that the building is in compliance with local floodplain management ordinances and aids in the proper evaluation of an insurance premium. The elevation certificate also can be used to support a request for a Letter of Map Amendment or Revision (LOMA OR LOMR-F).
