  9. 9.  Continue acquisition of land if/when available and install dunes  Continue dune grass planting & fencing  Planning & Zoning: local enforcement of existing state barrier beach regulations & exploration of other zoning regulations including Beach Overlay Districts  Incentives for developers to build “climate smart”, e.g. raising buildings Salisbury Beach at Broadway Future Adaptation Strategies
  10. 10.  Education of property owners and renters  Engagement with business owners and citizens groups such as the Salisbury Beach Partnership & Merrimack River Beach Alliance  Establish a Salisbury Resiliency Committee Salisbury Beach at Broadway Community engagement is critical & zoning is critical!

  19. 19.  Incorporate climate projections into master planning & future development  Business owner engagement  Better overall stormwater management & best practices  Explore building retrofits (e.g. drop-in flood barriers & longer term floodproofing) to reduce impacts of flooding  Explore opportunities for hybrid adaptation strategies in “hardened” areas of riverbank (e.g. Joppa Park) Future Adaptation Strategies Central Waterfront

  26. 26. Low-lying houses Future Adaptation Strategies  Enhanced property owner education, including the benefits of specific building retrofits such as “freeboard” (raising homes on stilts)  Freeboard incentives  Restoring flow with improved culverts, raising roads if possible Photo Credit: Pamela Merrill
  27. 27. Low-lying houses Future Adaptation Strategies  Establish conservancy district zoning overlay to prevent future development in flood-prone areas and to create a long-term buffer between development and flooding  Incorporate climate projections into long-term planning Research “rolling easements” as way to deal with the need in some low-lying places to retreat (if/when there is no other option)
