From Email to President Joseph Pluta (and other individuals) from County of Maui Maui Emergency Management Agency (MEMA)
"...below you will find some information about retrofitting homes to withstand major hurricane strength winds.
In 2010, FEMA developed guidance on retroftting your home to withstand a major hurricane to encourage mitigation of existing buildings in hurricane-prone areas. According to the ASCE (American Society of Civil Engineers) 7-05, the entire state of Hawaii is in hurricane-prone area. There are three (3) levels of mitigation measures when selecting a retrofit project for your home. They are: Basic, Intermediate, and Advanced.
Basic (or Intermediate) Retrofit: This measure focuses mainly on the building envelope such as enhancing the roof system, attic ventilation, wall structure, integrity, openings (windows, skylights, doors...etc.) and other attached structures.
Some examples of Basic and Intermediate retrofits are:
Some examples of the Advanced retrofits are:
(see: http://www.fema.gov/media-library-data/1424368115734-86cfbaeb456f7c1d57a05d3e8e08a4bd/FINAL_WindRetrofit_BCA_JobAid_13FEB15_508complete.pdf) they estimate a cost of an intermediate retrofit to be ~$24,000 (roof retrofit included). MEMA would strongly encourage the adoption of these FEMA guidelines into the future Lahaina building code. We also hope the county as a whole will adopt these guidelines in conjunction with a modern building code.
