Stormwater Management

What is Stormwater Management?

Stormwater management deals with efforts to handle the runoff of rainwater from streets and lawns, and reducing pollutants in waterways.

In urban areas, roofs and pavement prevent rainwater from soaking into the ground, so it can build up rapidly, causing flooding and other issues. This excess stormwater can carry pollutants and bacteria as it washes over surfaces and into drains instead of being absorbed into the soil and filtered naturally.

The S.C Sea Grant Consortium provides communities and decision-makers with science-based information and best practices on the management of stormwater.

Stormwater Ponds

Report cover.

Stormwater Ponds in South Carolina State of Knowledge Report (2018)

This comprehensive report contains up-to-date scientific findings on stormwater ponds, their effectiveness as a control measure, pollutant levels, public perception, and best management practices. Full report available soon.

S.C. Stormwater Pond Research and Management Collaborative

A collaboration to further investigate and address the challenges associated with stormwater ponds in our coastal areas. In late 2014, the Consortium initiated support for a series of seven studies related to stormwater ponds.

Stormwater Pollution

Polluted Stormwater in South Carolina

This publication explains nonpoint source pollution, or runoff pollution for the general public. It explains where stormwater pollution comes from and what can be done to reduce its impacts. It is also available at no cost as a printed brochure for distribution. Contact Susan Ferris Hill (Susan.Ferris.Hill@scseagrant.org) to request copies.

Research Reports

Runoff Volume Sensitivities of Tidal Headwaters (2015)

Nonpoint source pollution from stormwater runoff associated with large-scale land use changes threatens the integrity of ecologically and economically valuable estuarine ecosystems. Beaufort County, S.C. implemented volume-based stormwater regulations on the rationale that if volume discharge is controlled, contaminant loading will also be controlled. The County sought to identify which of their tidal creeks and what portions of the creeks are most sensitive to stormwater runoff.

Assessment of Stormwater Management in Coastal South Carolina: A Focus on Stormwater Ponds and Low Impact Development (LID) Practices (2010)

This report covers the strengths and weaknesses of two stormwater management strategies in coastal South Carolina: stormwater ponds and LID practices. Based on interviews of stormwater professionals and input from workshops, the report assists coastal communities with decision-making about the selection and implementation of stormwater managements strategies.

Chemical and Biological Contamination of Stormwater Detention Pond Sediments in Coastal South Carolina (2008)

This technical report characterizes the chemical and biological contaminants from sediment of 16 stormwater ponds located in suburban areas of Myrtle Beach, Georgetown, Charleston, and Beaufort.

Stormwater Education

S.C. Coastal Information Network

SCCIN provides education and training for community officials on topics such as water resources, stormwater ponds, and low impact development. The website features a wealth of handbooks and resources as well as a calendar of current training events.

Community Associations and Stormwater Management: A Coastal South Carolina Perspective

This publication provides practical insights for community associations that want to protect and improve their natural resources. Strategies covered include managing coastal runoff by using vegetated buffers and rain gardens, maintaining stormwater ponds, and other actions homeowners can take to improve water quality. Contains a helpful glossary of terms, web resources, native plant lists, and a maintenance checklist.
