Climatic and Geographic Design Criteria (Table R301.2(1)). <br /> <br /> Table R301.2(1) is revised to read: <br /> <br /> TABLE R301.2(1) <br /> CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA <br /> WIND DESIGN SUBJECT TO DAMAGE FROM <br /> GROUND Speed SEISMIC Frost WINTER ICE BARRIER AIR MEAN <br /> SNOW ° Topographic DESIGN line DESIGN UNDERLAYMENT FLOOD FREEZING ANNUAL <br /> LOAD (mph) effects" CATEGORY' Weathering ' Depth b ermite TEMP° REQUIRED" HAZARDS° INDEX' TEMP) <br /> Very See <br /> Zero 85 No D2 or E Negligible 12-24" Heavy 43 No Exhibit B 0 60 <br /> For SI: 1 pound per square foot = <br /> p 0.0479 kPa, 1 mile per hour _ 0.447 m/s. <br /> a. Weathering may require a higher strength concrete or grade of <br /> masonry than necessary to satisfy the structural requirements of this code. <br /> The weathering column shall be filled in with the weathering index (i.e., <br /> negligible, moderate or severe) for concrete as determined from the <br /> Weathering Probability Map [Figure R301.2(3)]. The grade of masonry <br /> units shall be determined from ASTM C 34, C 55, C 62, C 73, C 90, C <br /> 129, C 145, C 216 or C 652. <br /> <br /> b. The frost line depth may require deeper footings than indicated in <br /> Figure R403.1(1). The jurisdiction shall fill in the frost line depth column <br /> with the minimum depth of footing below finish grade. <br /> C. The jurisdiction shall fill in this part of the table to indicate the need <br /> for protection depending on whether there has been a history of local <br /> subterranean termite damage. <br /> <br /> d. The jurisdiction shall fill in this part of the table with the wind speed <br /> from the basic wind speed map [Figure R301.2( 4)].Wind exposure <br /> category shall be determined on a site-specific basis in accordance with <br /> Section R301.2.1.4. <br /> <br /> e. Temperatures shall be permitted to reflect local climates or local <br /> weather experience as determined by the building official. <br /> <br /> f. The jurisdiction shall fill in this part of the table with the seismic <br /> design category determined from Section R301.2.2.1. <br /> <br /> g. The jurisdiction shall fill in this part of the table with (a) the date of <br /> the jurisdiction's entry into the National Flood Insurance Program (date of <br /> adoption of the first code or ordinance for management of flood hazard <br /> <br /> <br /> Ordinance No. NSAXXX <br /> 11 A-24 Page 24 of 43 <br />
