Nonstructural Projects in the 2017 Coastal Master Plan

Several types of structures were evaluated including both residential and non-residential structures. Residential buildings included single family, multi-family, and manufactured homes. Non-residential buildings included commercial, industrial, and institutional structures.

  • Floodproofing: Recommended for non-residential structures in areas with flood depths of 3 feet or less.
  • Elevation: Recommended for residential structures in areas with flood depths between 3 and 14 feet (including two feet of freeboard).
  • Voluntary Acquisition: Recommended for residential structures which would need to be elevated greater than 14 feet .

CPRA’s Flood Risk and Resilience Program is envisioned as a state-led, coast wide, nonstructural flood mitigation program for coastal Louisiana parishes. CPRA developed a risk reduction strategy that coordinates state resources and prioritizes areas of high risk, while parishes will play a lead role in implementing projects and selecting specific structures to be mitigated. The program is intended to take advantage of nonstructural project funding outside federal grant programs in order to maximize flexibility and speed the implementation of “shovel ready” projects that further comprehensive coastal risk reduction goals. The 2017 Coastal Master Plan recommends 32 nonstructural project areas that include the mitigation 26,569 structures at a cost of $6.06 billion over the next 50 years. It should be noted that these recommendations are general and do not address any specific structures. Feedback from our working partnerships with the Community Focus Group, Parish Floodplain Managers Group, Flood Risk and Resilience Stakeholder Group and other coastal citizens was essential in developing this effort.
