(2) This table is informational only in that actual site elevations may vary. Table is only
valid if site elevation is within 100 feet of the listed elevation."
197 Utah Snow Loads. The ground snow load, Pg, to be used in the determination of design snow
198 loads for buildings and other structures shall be determined by using the following formula: Pg
199 = (Po2 + S2(A-Ao)2)0.5 for A greater than Ao, and Pg = Po for A less than or equal to Ao.
201 Pg = Ground snow load at a given elevation (psf);
202 Po = Base ground snow load (psf) from Table No. R301.2(5a);
203 S = Change in ground snow load with elevation (psf/100 ft.) From Table No. R301.2(5a);
204 A = Elevation above sea level at the site (ft./1,000);
205 Ao = Base ground snow elevation from Table R301.2(5a) (ft./1,000).
206 The building official may round the roof snow load to the nearest 5 psf. The ground snow
207 load, Pg, may be adjusted by the building official when a licensed engineer or architect submits
208 data substantiating the adjustments. A record of such action together with the substantiating
209 data shall be provided to the division for a permanent record.
210 The building official may also directly adopt roof snow loads in accordance with Table
211 R301.2(5b), provided the site is no more than 100 ft. higher than the listed elevation.
212 Where the minimum roof live load in accordance with Table R301.6 is greater than the design
213 roof snow load, such roof live load shall be used for design, however, it shall not be reduced to
214 a load lower than the design roof snow load. Drifting need not be considered for roof snow
215 loads less than 20 psf."
