Hamilton County Storm Water District

Flood plain managementThe City of Sharonville is a partner with the Hamilton County Storm Water District (HAMCO SWD), which was created to fund compliance with the US EPA National Storm Water Quality Permit. The on-going project includes:

  • Continued GIS mapping by CT Consultants
  • USGS stream gauges and related expenses
  • Payment to the HAMCO SWD for their part in EPA permit processing
  • Creation of a district storm water plan
  • Detention facility inspections
  • Dry weather screening outfall inspections


Storm Water District activities include board membership with the Hamilton County Storm Water District and the Mill Creek Alliance (MCA).

The Community Development Department conducts periodic inspections of all private (commercial/industrial) storm water detention facilities- such as storm water detention/retention. There are over 150 storm water facilities located in Sharonville. Inspection results may require enforcement notices to correct deficiencies and/or maintenance violations. 

Storm water drainage issues are a common complaint received by the City. Important storm water drainage information for Sharonville residents can be found here.

FEMA Flood Plain 

The City of Sharonville administers the Flood Damage Reduction Ordinance, which applies to all properties in the City of Sharonville that are located in the FEMA 100-year designated flood plain. A quick visual estimate appears to show that approximately 20% or more of Sharonville is in the flood plain. The city also assists and advises property owners with Elevation Certificates, processes and approves Special Flood Hazard Area (SFHA) permits for work in the designated flood plain. The City also partners with the Mill Creek Alliance to highlight the Mill Creek corridor and the creek itself as a natural asset for the region.
