|Use our ASCE Ground Snow Loads map to easily obtain the ground snow load (Figure 7-1 of ASCE 7-10) for any location in the contiguous United States. You can click on the map below to determine the design ground snow load, latitude and longitude and elevation for that location.
Non-shaded (CS) areas require site-specific Case Studies to establish ground snow loads. Extreme local variations in ground snow loads in these areas preclude mapping at this scale.
Site-specific case studies are also required to establish ground snow loads at elevations not covered.
If you need to gather ground snow load data programmatically, please consider our API Service.
Use our Roof Snow Load Calculator to determine your design roof snow loads.
Please review our State Snow Loads page to investigate state specific snow load requirements.
For additional questions or concerns about specific ground snow loads please call us at 1-425-741-5555.
