A Collaborative Review of the Coastal South Carolina LID Manual,
January 9, 2014

Summary: The ACE Basin and North Inlet-Winyah Bay National Estuarine Research Reserves, the Center for Watershed Protection, and South Carolina Sea Grant Consortium are pleased to announce a draft version for a Low Impact Development Manual for Coastal South Carolina. During the one-day workshop, 60 engineers, planners, landscape architects and other professionals from private & public organizations provided feedback on the current draft of the LID Manual. DHEC regulations related to LID were presented to attendees, as well as opportunities to incorporate LID successfully into coastal projects.  Attendees also broke into smaller groups to provide detailed critiques of the draft chapters in the manual related to planning, better site design, and technical specifications.

Participant discussion helped the project team address the following questions:

  • How does this LID manual conform with State stormwater requirements?
  • Are there any concepts in the manual that are unclear or require modifications?
  • Are the specifications for the structural BMPs sufficiently informative and appropriate for coastal application?
  • What local ordinances create incentives and opportunities for LID practices?

Workshop Agenda

Session A Notes: Review of Chapters 2 & 3

Session B Notes: Review of Chapter 4

Draft Coastal Low Impact Development Manual:

Please note that this is a draft version of the manual documents, and at this time is subject to change or additions of new material.  The draft version of the chapters, specifications, and spreadsheets are not intended for design use at this time.

Climate and Stormwater Roundtable, September 20, 2013

Summary: A group of 24 climate specialists, engineers, and coastal researchers met at the Department of Natural Resources Ft. Johnson MRRI classroom to discuss climate change, sea level rise, and their potential impacts on low impact development best management practices. At this roundtable discussion, the participants learned from climate specialists about the historical and projected climate patterns and how a particular stormwater model (SWARM) attempts to account for these changes when calculating stormwater runoff. The participants provided feedback for the best method for including information related to climate and sea level rise adaptations in the Low Impact Development Manual.

LID Research Roundtable, April 16, 2013

Summary: Nearly 20 scientists, engineers, and regulators met at the Discovery Center at the Hobcaw Barony to discuss current, local research as it pertains to low impact development practices for managing stormwater runoff in the coastal areas of South Carolina.  Research topics discussed included hydrologic impacts of urbanization, runoff predictions for coastal first-order watersheds, modified coastal streams, and pond management.  The group discussed specific physical limitations (e.g. high water tables and poorly drained soils) as well as pollutants of concern (nitrogen, phosphorus, sediment, and bacteria) as they related to LID implementation and modification.

Workshop #1, January 16, 2013

Summary: Over 50 engineers, planners, landscape architects, developers, and researchers from throughout the SC coastal zone joined the project team and advisory committee for this kick-off workshop. The workshop included an introduction of the project and project team, who addressed how stakeholder input has and will continue to inform this effort. The workshop included a brief overview of state stormwater regulations, which was followed by concurrent breakout sessions with technical and planning audiences. The project team led discussions with the attendees to further inform the content of the manual, including a discussion on case studies.
