City of Rock Hill

The City of Rock Hill is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Rock Hill will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. Post-construction stormwater regulations will also be enforced and applicable stormwater fees will be collected. The City of Rock Hill offers stormwater credits for properties with installed and maintained stormwater runoff control facilities, Best Management Practices (BMPs), and/or water quality controls. The City of Rock Hill, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite.
