Flood Zone MapA special flood hazard area is a land in the floodplain having a one percent or greater chance of flooding in any given year, as specifically identified in the Flood Insurance Study for the City.  The City of Rock hill is fortunate in having frontage on the Catawba River as well as streams and drainage ways which drain miles of water shed but can swell and inundate properties with surface water.  These conditions some times can result in property damage and potential injuries.  All property owners should be aware of precautions to protect against flooding.

The City of Rock Hill's Building/Floodplain Administrator, with decades of experience as a Floodplain Manager, provides one-on-one advice to citizens, contractors, and developers about property protection such as retrofitting techniques, and in conjunction with the Stormwater Division, drainage improvements. 

In order to fully understand the property and structures, the Building Official/Floodplain Administrator makes site visits before providing this advice.  If you are interested in taking advantage of this complimentary service, please contact Mike Nugent by email or at (803) 329-5598.

Please be advised that the City of Rock Hill can, at your request, provide Flood Zone Determinations from the most recent Flood Insurance Rate Maps (FIRM) prepared by FEMA.  The following is available upon request:

  • Which Flood Zone a property or area is located
  • The Base Flood Elevation
  • Flood Insurance basic information
  • Depth of potential flooding
  • Past flood or repetitive loss area
  • Sensitive or wetland area
  • Floodway area as shown on the Flood Insurance Rate Map (FIRM)

A complete library of development guideline materials from FEMA is available at City Hall, in the offices of Planning & Development, Suite 300, and at the York County Library, 138 East Black Street. Stream Gauge USGS provides real-time gauge information so users can see current water levels and, where available, flood height predictions. 

Completed elevation certificates for new construction and substantial renovations within flood zones are available for your review in individual property files.  Additionally, completed elevation certificates for all projects are kept in a separate file for easier access.

The City of Rock Hill also provides easy access to flood mapping information.  To view the flood map for your home's location, you may visit the Planning & Development Department located on the third floor of City Hall in Suite 300.  You can check your address online by going to Rock Hill GIS website.
