9.A.4. PUBLIC HEARING - ORDINANCE NO. 2002-008 DESIGNATING A WIND BORNE DEBRIS REGION THAT COINCIDES WITH FIGURE 1606 OF THE FLORIDA BUILDING CODE AND ADOPTING A BASIC WIND SPEED MAP (Legislative) PROOF OF PUBLICATION IS ON FILE IN THE OFFICE OF THE CLERK TO THE BOARD The Board reviewed a Memorandum of February 26, 2002: TO: James E. Chandler County Administrator D v ON HE'D CONCURRENCE: obert M. Keating, ICP Community Develop nt Di ctor FROM: Wayne H. Russ, C.B.O. Building Official DATE:Tuesday, February 26, 2002 SUBJECT: Request to adopt Indian River County Wind Speed Map. It is requested that the data herein presented be given formal consideration by the Board of County Commissioners at its regular meeting of March 5, 2002. BACKGROUND: On March 1, 2002, the new Florida Building Code went into effect statewide. This new code significantly changes building regulations throughout the state. Among those changes are new requirements associated with wind loads and wind-borne debris. To ensure consistent statewide application of wind requirements, the Florida Building Code includes Figure 1606(see "Exhibit 1 Wind" attached). Although Figure 1606 establishes wind speed contours for the entire state, the new Florida Building Code states that the exact location of wind speed lines shall be established by local ordinance using recognized physical landmarks such as major roads, canals, rivers, and lake shores, wherever possible. Recently passed legislation now requires that local jurisdictions bisected or otherwise divided by a line separating wind speed zones must by January 1, 2002, enact an ordinance specifying the exact location of wind speed lines, using recognized physical landmarks such as major roads, canals, rivers, and lake shores wherever possible. As shown in Figure 1606, Indian River County is bisected by three wind contours and therefore must adopt a Wind Speed Map. March 5, 2002 90 c r
