Old Village Drainage Study

In 2016, the Town of Mount Pleasant funded and began a high level of service needs study of the drainage infrastructure in the Old Village/ Old Mount Pleasant area of town. After several large rain events in 2015 and 2016, the department received an increase in reports of flooding.  The Town contracted with Thomas and Hutton Engineering to assess the current level of service provided by the area drainage systems, identify changes in development patterns, and evaluate reports of flooding the study identified critical needs for this older area of Town.  With the completion of the study Town Council has funded the design for drainage improvements in two drainage basins within the project's study area; Edwards Park and Royall Avenue.  This design work is currently in progress.

Stormwater Management Plan - Water Quality Protection

In 2007, the Town of Mount Pleasant, in compliance with State and Federal Water Quality requirements, developed a "stormwater management plan" (SWMP) for implementing a water quality protection program. The Town operates this program under a state NPDES discharge permit.

Under the permit, the Town is required to implement "Minimum Control Measures" or MCM that will help to protect or improve local water quality. South Carolina requires that the Town implement six (6) MCMs. The plan is updated as needed to reflect operation, administrative, or other programmatic changes are implemented. The initial plan covered 2007-2013. The Town recently completed an program review and compiled a 5-year plan for 2014-2018, to meet new permit requirements.

Please contact the Stormwater office for any additional information.

Shem Creek Watershed Study

In 2017, the Stormwater Division conducted a high level study of the Shem Creek Watershed to review existing data and to collect new data about pollution of the creek due to bacteria.  The study resulted in a presentation on the findings, a presentation on 9-Element Plans, a recommendation to Staff and Town Council to consider funding and completing the development of a 9-Element Watershed Plan, and three information sheets to detail the study information.  A formal report was replaced with an online tool that is currently in development.
