Publications Offer Alternative Stormwater Management Strategies

Feb 2, 2010 | News

Some innovative developments have installed low-impact development (LID) technologies to capture rainfall and treat it by filtration onsite, as close to where it falls on the ground as possible. In this way, rainfall is filtered before it ever reaches detention ponds or waterways.

Now a new brochure that highlights LID strategies for residential communities is available. The brochure is part of a stormwater series focusing on stormwater-management practices such as pocket parks, bioretention swales, and pervious pavement implemented in North Charleston’s Oak Terrace Preserve residential community.

This publication is a collaborative effort of the S.C. Sea Grant Extension Program, the University of South Carolina, the Noisette Company, and the City of North Charleston.

In addition, after a two-year study of LID strategies at Oak Terrace Preserve, S.C. Sea Grant Consortium researchers Dwayne Porter and Lisa Vandiver, of the University of South Carolina Department of Environmental Health Sciences, provided a summary of “lessons learned” for homeowners.

From Consortium research results, a LID maintenance manual providing guidance to homeowners associations was created. The guidance document provides general information about inspecting and maintaining bioretention swales, pervious alleys and walkways, and pocket parks. Many homeowners associations are responsible for maintaining these technologies.

Finally, a new research project report, An Assessment of Stormwater Management in Coastal South Carolina: A Focus on Stormwater Ponds and Low Impact Development (LID) Practices, is available.

The report addresses issues of water quality, the permitting process, and stormwater management project design, construction and maintenance, strengths and weaknesses of stormwater ponds, and LID practices. The report is based on information gathered through interviews with stormwater professionals and from participants of a January 2009 coastal South Carolina stormwater management workshop.

The report is intended to assist coastal communities and others in making decisions regarding the selection and implementation of stormwater management strategies.
