Sediment and Erosion Control

Background

Development and redevelopment converts former pervious surface soils to non-pervious man-made surfaces, which then produces increased runoff volumes and flows. The physical problems resulting from this increased runoff includes, but are not limited to, flooding, soil erosion, sedimentation, and the pollution of lands and surrounding water bodies.

Construction sites must adhere to the Town of Bluffton’s Stormwater Ordinance as outlined in the Unified Development Ordinance (UDO) and the Stormwater Design Manual and utilize appropriate Best Management Practices (BMPs) to ensure control of soil erosion.

Enforcement

Construction site inspections for sediment, erosion, and stormwater runoff controls are conducted by an inspector, bearing proper credentials and identification, to ensure that the construction adheres to the approved plans to curb and/or remediate the physical effects of land disturbance. 

Any deficiencies or non-compliance issues identified during a Town inspection will be reported to the project contractor, on-site supervisor, and/or engineer for addressing. Some corrective measures may require immediate, 2-5 days’ time frame depending on the nature of the violation. 

Failure to address concerns or implement and corrective measures will result in the issuance of Notices of Violation, Stop Work Orders and/or fines. To find out more information about the enforcement of the sediment and erosion control program, see the Erosion and Sediment Control Enforcement Response Plan (ERP).

BMPs that have frequent failures can be required to be replaced with alternative control methods. All changes should be communicated with the Watershed Management Division and documentation in the On-Site Stormwater Pollution Prevention Plan (OS-SWPPP).

Education

The Town of Bluffton’s Watershed Management Division developed two (2) handouts to educate builders, subcontractors, and developers on the importance of stormwater BMPs at active construction sites. These handouts are:

  1. Sediment and Erosion Control Practices for Single Family Home Builders and 
  2. Stormwater BMPs for Contractors and Subcontractors
