Why Snow Load Information?
A great deal of confusion currently exists among engineers, architects,
recreation specialists, and maintenance personnel concerning the proper
snow loading to use for the design and maintenance of trail bridges,
building roofs, and other structures in mountainous, high snow load
Snow loads are influenced by elevation, general weather and moisture
patterns, slope direction, exposure, roof (or trail bridge) configuration,
and wind direction and severity.
Overestimation of snow loads can unnecessarily increase the cost
of construction. Underestimation of snow loads can result in premature
failure, high maintenance costs, resource damage, and, in some cases,

Purpose of This Web Site
The purpose of this Web site is to provide ground
snow load analysis
information and data gathered from all 50 States. Each state has
a listing of
building code and applicable guidelines for snow loads, as well as
details about where the snow load information may be found or purchased.
Please refer to the International Building Code (IBC) (http://www.iccsafe.org/e/category.html)
or ASCE 7, Minimum Design Loads for Buildings and Other Structures
for roof snow load determination and
