Non-Structural Shore Protection

Because of the many problems with flood and erosion control structures, there has been a shift in recent years toward non-structural shore stabilization techniques. Non-structural shore protection measures generally seek to enhance the natural ability of shorelines to absorb and dissipate storm energy without interfering with natural beach, dune, and bank processes.

For an overview table of shore protection options in Massachusetts, see the Massachusetts Coastal Hazards Commission’s final report–Preparing for the Storm: Recommendations for Management of Risk from Coastal Hazards in Massachusetts, Appendix C.

Some non-structural shore protection techniques for your community to consider include:

• Renourishing beaches and dunes. See the Massachusetts Department of Environmental Protection’s (MassDEP) best management guidance (PDF, 1.6 MB) and technical attachments (PDF, 1.15 MB).
• Stabilizing dunes with fences and vegetation. (This approach may be prohibited in endangered species habitat. For more information see the Massachusetts Office of Coastal Zone Management’s [CZM] Barrier Beach Management in Massachusetts webpage and consult the MassWildlife Natural Heritage and Endangered Species Program). For detailed information on techniques, see the University of Massachusetts (Umass) Extension’s brochure Selection and Maintenance of Plant Materials for Coastal Landscapes (PDF, 69 KB) for ideas on which plants might be most appropriate. Be sure to avoid invasive species, which may create their own problems. Check to see if a plant is potentially invasive at the Invasive Plant Atlas of New England webpage.
• Protecting, nourishing, or constructing dunes. See CZM’s Barrier Beach Management in Massachusetts webpage and the Massachusetts Department of Environmental Protection's Guide to Best Management Practices for Projects in Massachusetts (PDF, 1.6MB) and the guide's technical attachments (PDF, 1.15 MB).
• Re-vegetating/stabilizing shorelines and/or riparian (river) corridors with native plants. See UMass Extension’s brochure Selection and Maintenance of Plant Materials for Coastal Landscapes (PDF, 69 KB).
• Creating or restoring wetlands. See the Massachusetts Wetlands Restoration site.
• Prohibiting or more stringently restricting the infill of wetlands. Your community may wish to adopt a local wetlands bylaw or ordinance to do this. See the Massachusetts Association of Conservation Commission’s model wetlands bylaw/ordinance.
