Town of Mount Pleasant
The Town of Mount Pleasant has developed a Stormwater Management Program in order to reduce the discharge of pollutants from the Town of Mount Pleasant’s Small Municipal Separate Storm Sewer System (SMS4) to the maximum extent practicable, to protect water quality and to satisfy the appropriate requirements of the Clean Water Act. The Town of Mount Pleasant 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 Town of Mount Pleasant 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, including regular inspections. Charleston County will handle the collection of stormwater fees within Mount Pleasant. The Town of Mount Pleasant, 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.
4.2.5 Post-Construction Stormwater Management for New Development and Redevelopment
188.8.131.52 Minimum Measure #5 Permit Requirements
The post construction stormwater management program is designed to give The Town of Mount Pleasant the authority to require structural and non-structural stormwater quality BMPs on sites being developed. The Town of Mount Pleasant currently provides design requirements to control stormwater discharges from new development and redeveloped sites and has established performance standards for addressing the first inch of runoff. The Town of Mount Pleasant will improve the post construction program by developing additional or revising existing site performance standards and ensuring post construction BMPs are inspected and maintained appropriately.
184.108.40.206 Long-term maintenance of post-construction stormwater control measures:
All structural stormwater control measures installed and implemented to meet the site performance standards will be maintained in perpetuity. The Town of Mount Pleasant will ensure the long-term maintenance of structural stormwater control measures installed.
The Town of Mount Pleasant will require that property owners or operators of any new development or redeveloped site subject to the site performance standards will provide verification of maintenance for the approved structural stormwater control measures used to comply with the performance standards.
220.127.116.11 Inspections and enforcement:
18.104.22.168.1 Inspection procedures:

22.214.171.124.3 Inspection reports:
The Town of Mount Pleasant will document its inspection findings in an inspection report. The Town of Mount Pleasant will document and maintain records of inspection findings and enforcement actions and make them available for review by the permitting authority.
