Stormwater can pick up debris, chemicals, dirt and other pollutants and flow into a storm sewer system or directly into a lake, stream, river, wetland or coastal water. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing and providing drinking water.
Every few years, the Federal Emergency Management Agency (FEMA) prepares maps of areas susceptible to flooding. The latest version of Union County’s flood zone maps can be viewed by stopping by the planning office or viewing the 2014 FEMA Zones map on the County’s GIS/Maps webpage. To view the FEMA flood zones, click on the GoMaps 4.0 link on the County's GIS/Maps webpage. Open the 'map layers' dialog box, and select the 2014 FEMA zones layer under the Natural map layers heading. Then zoom in to the area on the map which you want to observe.
The regulations that apply to land within designated flood-prone areas can be found in Article 65 of the Union County Development Ordinance.

The stormwater section strives to protect local water quality, control flooding and reduce impacts to private properties from developments by informing developers of federal, state and local regulations related to stormwater and floodplain management and as well as assistance through the plan approval process. This section’s responsibilities include stormwater plan review, FEMA floodplain development review and site inspections for subdivisions in unincorporated Union County and the Town of Hemby Bridge. This section recommends policy development and provides technical assistance regarding stormwater management and floodplain development within The Planning Division and to other Union County departments. Staff also responds to drainage complaints from the public as required and coordinates stormwater public education efforts.
