Environmental & Emergency Management
Natural Functions
Under natural conditions, a flood causes little or no damage. Nature ensures that floodplain flora and fauna can survive the most frequent flooding. Natural areas (those without development) help reduce our flood damage by allowing flood waters to spread over a large area. This reduces water velocities and provides flood storage to reduce peak flows downstream. It is our job to preserve natural areas in the floodplain whenever possible. The city has adopted ordinances to reduce future development in our natural floodplain areas. The city also has an ongoing commitment to work with its surrounding jurisdictions because of the impact that development in these areas has on flooding in Roanoke.
