Floodplain Maps

Floodplain Maps

OVERVIEW

Floodplain maps provide the basis for flood management, regulation and insurance requirements by identifying areas subject to flooding which threaten life safety and damage to property.  These maps then guide the community in adopting flood management programs including floodplain preservation, preparedness, education, regulation and mitigation.  The city floodplain map is available online to assist the public in identifying flood-prone properties.
