<br />No supplemental concrete foundation pours which create a hidden cold joint shall be used without
<br />supplemental treatment in the foundation unless there is an approved physical barrier. An approval
<br />physical barrier shall also be installed from below the wall sill plate or first block course horizontally to
<br />embed in a mortar joint. If masonry veneer extends below grade, a termite protective treatment must
<br />be applied to the cavity created between the veneer and the foundation, in lieu of a physical barrier.
<br />Exception: Veneer supported by a structural member secured to the foundation sidewall in
<br />accordance with ACI 530/ASCE 5/TMS 402, provided at least 6 inch (152 mm) clear inspection space
<br />of the foundation sidewall exterior exists between the veneer and the top of any soil, sod, mulch or
<br />other landscaping component, deck, apron, porch, walk or any other work immediately adjacent to or
<br />adding the structure.

<br />Condensate lines, irrigation / sprinkler system risers for spray heads, and roof downspouts shall
<br />discharge at {east 1 foot (305 mm) away from the structural sidewall, weather by underground piping,
<br />tail extensions or splash blocks. Gutters with downspouts are required on all buildings with eves of
<br />less than 6 inches (152 mm) horizontal projection except for gable end rakes or on a roof above
<br />another roof.

<br />R 318.6.1 All building sites shall be graded to provide drainage under all portions of the building not
<br />occupied by basements.

<br />vegetation, stumps, dead roots cardboard, trash and foreign material removed and the fill material
<br />shall be free of vegetation and foreign material. The fill shall be compacted to assure adequate
