Creating a Community Master Plan

A community master plan allows your community to recommend zoning strategies to guide private and public projects away from areas where they would likely put people and property at great risk. Ideally, plans would reserve the most hazardous areas (e.g., V and coastal A Zones on Flood Insurance Rate Maps, areas at risk from storm surge, floodways) for parks, greenways, golf courses,  agriculture, support of navigation or wetlands banks, or similar open space. The master plan can also identify areas that are priorities for land acquisition efforts (see the funding section).

The following sites have information on creating master plans:

Floodplain-Specific Master Plan Information

• The Federal Emergency Management Agency (FEMA) Coastal Construction Manual offers excellent information on issues associated with development in floodplains, particularly:
  • Section 2.2 and 2.3, which 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, which covers the legal requirements of compliance with the National Flood Insurance Program (NFIP), including what land uses are and are not allowed.
  • Section 6.5, which provides recommendations for exceeding NFIP minimum standards.
  • Chapter 7, which covers the importance of identifying hazards in the planning process.
  • Chapter 8, which 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 is a great source for information on how to safely use floodplains. Their NAI Toolkit (PDF, 2 MB) is particularly useful for local officials, as is their Coastal NAI Handbook.
• 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.

Planning with Historic Properties

• For communities with historic properties, FEMA publishes Integrating Historic Property and Cultural Resource Considerations Into Hazard Mitigation Planning:  State and Local Mitigation Planning How-To. This FEMA document discusses the flexibility that FEMA allows when planning how to protect historic properties and cultural resources. To obtain a free copy contact the FEMA Publications Distribution Facility at (800) 480-2520 or you can download it.
• FEMA publishes the Floodplain Management Bulletin on Historic Structures to explain how the National Flood Insurance Program (NFIP) defines historic structures and how it gives relief to historic structures from NFIP floodplain management requirements. This bulletin also provides guidance on mitigation measures that can be taken to minimize the devastating effects of flooding to historic structures.

Smart Growth in Coastal Areas

Consider adding Smart Growth techniques, such as Transfer of Development Rights (TDR), to the master plan. (TDR is a regulatory strategy that harnesses private market forces to permanently protect open space by “transferring” development from areas that a community wishes to protect to other areas more suitable for development.) In addition, Low Impact Development (LID) techniques and practices offer additional strategic advantages for inland floodplain management, such as planning to work with existing natural resources and on-site stormwater management that can reduce flooding. Whatever your planning approach, make certain that you are making appropriate choices that consider your community’s specific hazard vulnerabilities. For example, while high-density housing can reduce environmentally damaging urban sprawl, it’s not generally appropriate in a floodplain because it can expose additional structures to flood damage and adversely affect the floodplain’s natural ability to provide storm damage protection and flood control. Check out NOAA’s Coastal and Waterfront Smart Growth website for more information on how your community can guide development in ways that make it safer, nicer, and more prosperous.

For smart planning, check out the new Louisiana Land Use Toolkit site for model codes that will facilitate sustainable development (just beware that there’s no coastal component).

Your community may also want to see how its plan matches up with the goals of the Coastal Protection and Restoration Authority‘s goals and guidelines.

Notes from the folks at CRS:

“Activity 520 recognizes the importance of linking the floodplain management plan with other planning studies and with development, redevelopment and population trends. A community master plan may also include information on the impacts of flood hazards on the population, buildings, public safety, critical facilities, and the community’s economy and tax base. Usually, the master plan will also address the need to protect wetlands, sensitive areas, the habitat for rare or endangered species, and to protect the other natural and beneficial functions of the floodplain.”
