We recently completed a project for the Structural Engineers Association of Colorado (SEAC) to create a map of the average snow load across the state of Colorado. They provided an Excel spreadsheet of 400 sample locations each with the latitude and longitude and average snow load (pounds per square foot). We plotted this data and then interpolated the points into a surface from which we could create contour lines. The map was printed at 24″ x 36″ and we were very pleased with the results.
If you would like more information about obtaining a copy of the map, please contact SEAC directly.



Where can you purchase a copy of the snow load map?Thanks

Would like to know if you would be so kind as to donate a copy of your snow load map to my company. We have the hardest time assisting our customers in thier building needs because of the extreem differance in ground snow loads in the state of Colorado.
Thank you

@Shaun – You would have to contact the Structural Engineer Association of Colorado directly. We don’t have any copies of the map.
This is a Great idea for the GIS Community
What is the snow load for a slanted roof in Carbondale, CO. zip code 81623? If the roof of a house is 110 Lb./SF base, is that high enough?
Thank you. L.K
The map is useful , but could you provide the exact data listing all details of ice loading and snowfall rate or leave a hint to trace them. Thank you.
