An alternative interpretation is that "last contour" refers to the last <br />contour within a jurisdiction as depicted on Figure 1606. Since the last <br />contour on Figure 1606 in most of Indian River County is the 130 mile per <br />hour contour located at 82nd Avenue, this interpretation would allow the <br />area east of 82nd Avenue, where there is no 140 mile per hour contour <br />eastward, to use the 130 mile per hour wind speed. Consequently, the wind <br />speed for this area under this interpretation would be 130 miles per hour, <br />compared to the staff interpretation of this being 140 miles per hour. <br />To resolve this issue, staff has filed a Petition for Declaratory Statement <br />with the Florida Building Commission, the only entity with the authority to <br />make an official definition. Although this petition will not be considered <br />for several weeks, staff recommends that the Board adopt the Wind Speed Map <br />as proposed. <br />RECOMMENDATION: <br />Staff recommends that the Board of County Commissioners adopt the proposed <br />Ordinance. <br />ATTACHMENTS: <br />1. Proposed Ordinance 2002- <br />2. A. Exhibit 1 Wind - FBC Figure 1606. <br />B. Exhibit 2 Wind - DCA Wind Line Map Indian River County. <br />C. Exhibit 3 Wind - Indian River County Wind Speed Map <br />Building Division Director Wayne Kuss mtroauced his assistant "Buddy" Akins who <br />made a presentation concerning this proposed ordinance. <br />Deputy Building Official James "Buddy" Akins reviewed the above memorandum, <br />comprehensively explained the evolutions of the contour maps, and gave information about <br />the ` interim" map for Indian River County. He pointed out the wind contours and how <br />those wind speeds could be interpolated between the contours and are allowed within the <br />code. He explained how the Indian River County map is designed as a tool for the builder, <br />developer; or designer to determine the basic speed for the location of his project. If the <br />buildings are designed to the values presented on that map, they will meet the code <br />requirement. We will accept documentation of interpolation between the contours from their <br />engineer should they desire to use a lower wind speed. He explained in detail the lines and <br />the controversy which has arisen because of the interpolation and the reasons why it has <br />arisen. For these reasons, the Building Division's staff has been telling people to build <br />March 5, 2002 <br />92 <br />BK P G 9 <br />
