BUILDING ADAPTATION SUMMARY

The following slides show the recommended floodproofing measures that could be deployed at each building site as well as the high-level benefits and costs. The red line on each building represents current day (May 2023) floodproofing requirement for this flood zone.

Current day FEMA floodproofing requirement

The following assumptions were made in the BCA:

 Due to multiple buildings had varying uses and types due to having multiple store fronts in a single structure. The least beneficial building use and type were used to produce more conservative benefits.

 For the Elevation Action in Alternative 1, it was assumed that the buildings would be acquired and demolished, the businesses relocated, and that redevelopment would be part of a private investment. Redevelopment and relocation costs were not included in the BCA.

 For the Acquisition Action in Alternative 2, it was assumed that the buildings would be acquired and demolished, the businesses relocated, and the property redeveloped into a greenspace. Relocation costs were not included in the BCA.

 For the greenspace in Alternative 2, it was assumed that all acquired properties’ land and the parking lot behind them would turn into a greenspace.

 Additional assumptions and generalizations were made and can be refined if this BCA is submitted as part of a FEMA grant application. The assumptions and generalizations were made to provide a more conservative BCR and are listed in further detail the Benefit-Cost Analysis Summary Memo.
