Where weathering requires a higher strength concrete or grade of masonry than <br /> necessary to satisfy the structural requirements of this code, the frost line depth <br /> strength required for weathering shall govern, The weathering column shall be filled in <br /> with the weathering index, "negligible," "moderate" or "severe" for concrete as <br /> determined from Figure R301.2(1). The grade of masonry units shall be determined <br /> from ASTM C34, ASTM C55, ASTM C62, ASTM C73, ASTM C90, ASTM C129, ASTM <br /> C145, ASTM C216 or ASTM C652. <br /> b. Where the frost line depth requires deeper footings than indicated in Figure R403.1(1), <br /> the frost line depth strength required for weathering shall govern. The jurisdiction shall <br /> fill in the frost line depth column 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 for protection <br /> depending on whether there has been a history of local subterranean termite damage. <br /> Ordinance No. NS-3088 <br /> Page 7 of 27 <br />
