Well-meaning but antiquated local regulations often encourage or even require land use practices inappropriate for coastal floodplains. For example, regulations requiring curbs and wide paved roads may increase flooding and erosion in coastal floodplains.
The resources below provide information on how communities can allow development while reducing pressure on municipal services, infrastructure, and budgets. The practices that your community adopts should be compatible with floodplain development, and shouldn’t, for example, create higher housing density in areas prone to flooding.
- FEMA’s Coastal Construction Manual offers excellent background on the challenges of development in floodplains, as well as specific recommended practices—check to see if your community allows and encourages them. See, in particular, these sections:
- Section 2.2 and 2.3 provide an excellent overview of historic storm events and their often forgotten effects, as well as lessons learned that can inform future planning for development and redevelopment.
- Section 6.4.3 covers the legal requirements of compliance with the National Flood Insurance Program, including what land uses are and are not allowed (see incorporating National Flood Insurance Program (NFIP) requirements into local ordinances and regulations).
- Section 6.5 provides recommendations for exceeding NFIP minimum standards.
- Chapter 8 gives recommendations on how to develop “raw” land, as well as redeveloping land. (Figure 8-5 provides a simple “Do & Don’t” list for land use in coastal areas.)
To obtain a free copy of the Coastal Construction Manual (in print or on a CD), contact the FEMA Publications Distribution Facility at (800) 480-2520.
- The Association of State Floodplain Managers’ Coastal NAI Handbook has specific regulatory recommendations.
- The Resilient Coast: Policy Frameworks for Adapting the Built Environment to Climate Change and Growth in Coastal Areas of the U.S. Gulf of Mexico (PDF, 3.1 MB), is a publication examining existing legal and policy frameworks that might hinder or facilitate adaptation to changes brought about by global climate change and population growth in coastal communities along the U.S. Gulf Coast.
* Your community needs only 500 points to qualify for reduced flood insurance premiums through the Community Rating System (CRS). For more information (including how to apply for the CRS program), see our Community Rating System (CRS) primer.
Notes from the folks at CRS:
“Many communities have discovered that NFIP’s minimum standards do not provide adequate protection from their flood risk. CRS recognizes higher construction standards including freeboard, coastal A Zone standards, enclosure restrictions and coastal erosion setback regulations.”
