(Grade 40) <br />4. <br />Vertical reinforcement shall be placed nearest the inside face of the wall a distance d from the outside face <br />(soil side) of the wall where d equals 4” for a 5.5” wall, 5.5” for a 7.5” wall, 7” for a 9.5” wall and 9” for a <br />11.5” wall. The reinforcement shall be placed within a tolerance of +/- ½ inch. In no instance shall concrete <br />cover for reinforcement be less than 1 inch from the inside face of the wall, nor less than 3 inches from the <br />outside face of the wall. <br />5. <br />Soil classes are in accordance with the United Soil Classification System. Refer to Table R405.1. Group IV <br />soils require a design prepared by a registered design professional. <br />6. <br />Unbalanced backfill height is the difference in height of the exterior and interior finish ground levels. <br />Where there is an interior concrete slab, the unbalanced backfill height shall be measured from the exterior <br />finish ground level to the top of the interior concrete slab. <br />7 <br />. Concrete stem walls not exceeding 5 feet in height, supporting less than 4 feet of unbalanced backfill, are <br />exempt from the lateral bracing requirements of Section R404.1. <br />8 <br />. Concrete stem walls exceeding 5 feet in height, or supporting more than 4 feet of unbalanced backfill, shall <br />comply with the lateral bracing requirements of Section R404.1. (All 10 foot high walls shall be braced in <br /> <br />accordance with Table R404.1(1) as shown for 9’ walls with 9’ of unbalanced backfill.) <br />The County of Hawai‘i is an Equal Opportunity Provider and Employer <br /> <br /> <br />101 Pauahi Street, Suite 107 74-5044 Ane Keohoklole Hwy <br />ā <br />Hilo, Hawai‘i 96720 Kailua-Kona, Hawai’i 96740 <br /> <br />Tel: (808) 961-8331 Page 22 Tel: (808) 323-4720 <br /> <br />
