ASCE Ground Snow Loads TM

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.

With the release of ASCE 7-22, the ASCE is making their Hazard Tool available for free public access. With the availability of ASCE’s Hazard Tool, we feel there is no longer a unique need for the national snow load map provided by the Medeek website, and we will be deferring to the ASCE for providing free ground snow load information. This map will be retired on Mar. 1, 2025 and may become unavailable for use at that time. Note that the state specific snow load maps will remain active and will not be retired.
* Ground snow loads derived from Figure 7-1 of ASCE 7-10, with permission from ASCE. Local codes and ammendments may govern, verify with local building department or jurisdiction.

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.
