III. RECENT PUBLIC WORKSHOPS During the workshops, County staff from the Building Department again explained and clarified proposed changes to the Hawai'i County Building Code. The primary presenters during the most recent workshops were: • Neil Erickson, Architect and Plans Examiner for DPW. • Ray Tanabe, Meteorologist in Charge of the NOAA National Weather Service Forecast office in Honolulu. • Gary Y.K. Chock, S.E., author of Modeling of Topographic Wind Effects in Hawai'i and Modeling of Hurricane Damage for Hawai'i Residential Construction and Topographic Wind Speed -up and Directionality Factors for Use in the City and County of Honolulu Building Code and the Multi- Hazard Pre - Disaster Mitigation Plan for the City & County of Honolulu; former president of the Structural Engineers Association of Hawai'i; and member of the State Building Code Council. Neil Erickson compared administrative changes to the current code, chapter 5 regarding wind -load, partially enclosed structures, emergency preparedness, specifications & plans, violations, permits, and pre- approved package homes. Mr. Erickson's presentation materials from the most recent public workshops are included as Attachment 1. Ray Tanabe briefed the audience on "Central Pacific Hurricane Center and 2011 Hurricane Preparedness." Mr. Tanabe addressed the history of tropical cyclones, tropical cyclone impacts, and typical "myths" regarding tropical cyclones. Mr. Tanabe also stated: 1) all islands in Hawai'i are at equal risk; 2) there is a 1 out of 15 chance of hurricane winds somewhere in Hawai'i every year; 3) the islands do not have enough land mass to draw energy from a tropical cyclone to weaken the storm system. Mr. Tanabe's presentation materials from the most recent public workshops are included as Attachment 2. Gary Y.K. Chock, S.E. spoke on "Hawaii Wind Design Requirements for Hurricanes." Mr. Chock explained how technical committees collaborated in the creation and evolution of the technical language of the building code and ASCE7 in regards to wind design. Mr. Chock also addressed the obsolete calculations and formulas relied upon by the Uniform Building Code and the best modern methods of calculation relating to wind design that are a part of the IBC. According to Mr. Chock, the national model codes have adopted accredited national standards like ASCE 7 so that detailed technical provisions can be developed in a non - political environment and be subject to peer review by those with nationally recognized expertise. The International Code Council adopts such standards by reference and sometimes extracts key portion of text to include in the codes. Mr. Chock's presentation materials from the most recent public workshops are included as Attachment 3. County of Hawai' i is an Equal Opportunity Provider and Employer.
