895 if site elevation is within 100 feet of the listed elevation."
896 (8) IRC, Section R301.6, is deleted and replaced with the following: "R301.6 Utah
897 Snow Loads. The ground snow load, Pg, to be used in the determination of design snow loads
898 for buildings and other structures shall be determined by using the following formula: Pg = (Po2
899 + S2(A-Ao)2)0.5 for A greater than Ao, and Pg = Po for A less than or equal to Ao.
900 WHERE:
901 Pg = Ground snow load at a given elevation (psf);
902 Po = Base ground snow load (psf) from Table No. R301.2(5a);
903 S = Change in ground snow load with elevation (psf/100 ft.) From Table No. R301.2(5a);
904 A = Elevation above sea level at the site (ft./1000);

905 Ao = Base ground snow elevation from Table R301.2(5a) (ft./1000).
906 The building official may round the roof snow load to the nearest 5 psf. The ground snow load,
907 Pg, may be adjusted by the building official when a licensed engineer or architect submits data
908 substantiating the adjustments. A record of such action together with the substantiating data
909 shall be provided to the division for a permanent record.
910 The building official may also directly adopt roof snow loads in accordance with Table
911 R301.2(5b), provided the site is no more than 100 ft. higher than the listed elevation.
912 Where the minimum roof live load in accordance with Table R301.6 is greater than the design
913 roof snow load, such roof live load shall be used for design, however, it shall not be reduced to
914 a load lower than the design roof snow load. Drifting need not be considered for roof snow
915 loads less than 20 psf."
