Keep in mind any elevations above 1,000 feet, the ground snow load shall be increased from the mapped value by 2 psf for every 100 feet above 1,000 feet. Then if feasible a hard copy map can then be generated with NGSL isolines similar to the Idaho Ground Snow Load map. For sites in these states, users are directed to individual state tables with elevation and ground snow load for … Exposure. Elevation. To mitigate this "peak effect", the predictions in the map are not allowed to extend beyond the highest 50-year station ground snow load, which is approximately 429 psf. Infrequent, irregular, short duration snowfalls and single isolated very heavy snowfalls need to be taken into account when determining the characteristic values of ground snow loads for use in structural design. Ground and Roof Snow Loads for Idaho. The latitude and longitude of the site may be entered on the top line. Since values are extrapolated rather than interpolated, the estimated values for snow loads at elevations significantly higher than nearby stations sometimes lead to unreasonably high snow load estimates. 3. Use this information as a guide in constructing a building that will hold up for many years in our rugged climate. Warren County Human Services Building 3 rd Floor 1340 State Route 9 Lake George NY 12845. Permitting & Land Use Maps. Comprehensive Plan Maps.
