The design�riteria used include camponei�ts a�nd cladding elements, an assumed importAnce factor of <br /> 1.0,a maximum mean roof height of 35',and buildings both enclosed or partially enclosed. <br /> 7. Exposure categories(A, B,C,D) � - <br /> Exposure A—Large city centers with at least 50 percent of the buildings having a height in excess of <br /> 70 feet. Use of this exposure category shall be limited to tliose areas for which terrain representative <br /> of Exposure A prevails in the upwind direction for a distance af at Ieast 0.5 mile or I O times the <br /> height of ihe building or other structure,wl�iehever is greater. Possible channeling effects or <br /> increased velocity pressures due to the building or structure being located in the wake of adjacent <br /> buildings shall be taken iiito account. <br /> Exposure B—Urban and suburban areas,wooded areas,or other terrain with numerous closely <br /> spaced ubstructions having the size of single-family dwelEings or larger. Exposure B shall be <br /> assumed unless the site meets the definition af another type exposure. <br /> Exaosure C—Open terrain with scattered obstructions, including starface undulations or other <br /> irreguiarities, having heights generalty less tl�an 30 feet extending more tban 1,540 feet from the <br /> building site in any quadrant. This exposure shall also apply to any bailding located within exposure <br /> B type terrain where the building is directly adjacent to open areas of Exposure C type tenain in any <br /> quadrant for a distance of more than 600 fect. This catcgory includes flat open covntry,grasslands <br /> � � and shorelines in hvrricane-prone regions. <br /> 6-17 <br /> Issued on: 10/!/2003 <br /> Rclease: p <br />
