1608.2 Ground snow loads. The ground snow loads to be used in determining the design snow loads for roofs are given in Figure 1608.2 for sites at elevations up to 1,000 feet (304 m) in elevation. Sites at elevations above 1,000 feet (304 m) shall have their ground snow load increased from the mapped value by 2 psf (0.095 kN/m2) for every 100 feet (30 480 mm) above 1,000 feet (304 m). Site-specific case studies may be made in lieu of snow loads in Figure 1608.2. Ground snow load determination for site-specific case studies shall be based on an extreme value statistical analysis of data available in the vicinity of the site using a value with a 2-percent annual probability of being exceeded (50-year mean recurrence interval).





For Si: 1 foot = 304.8 mm, 1 pound per square foot = 0.0479 kN/m2.
