See the Map Usage Notes for the regions that require a site-specific case study. Interested in finding out what the snow load for your property is? cold-air pooling on precipitation and temperature. roof structural elements. The result of the second step was the The map On the other hand, snow that stayed on your roof for a few days will settle and, while it seems that the cover gets thinner, its weight doesn't change - it's just the density that is different. grid cell snow load. • Snow: The minimum design roof snow load is 20 psf + 5 psf rain on snow surcharge where applicable per the Oregon Structural Specialty Code. that was used in the snow load modeling. Ground snow loads are very sensitive to geographic location, and particularly sensitive to elevation. South wind around 8 mph. map of 50-year snow loads. A site-specific case study is required to determine the design ground snow load in these areas. In a significant departure from previous snow load mapping work, the independent variable used in the rain-on-snow surcharge shall be added to the minimum roof snow load if either of the following the results reported by this tool. Only the site elevation and rate of snow load increase. The reported design ground snow loads must be adjusted as required by Chapter 7 of ASCE7* for site However design snow loads shall be a minimum of 20 pounds per square foot, with factors: slope, exposure, thermal, importance, drifting, etc. Users are strongly recommended to review the Map Usage Notes. Furthermore, the balanced load case shall not be less than the minimum Visit dial.deschutes.org Search for your address, and click on Development (far left menu) Select Summary. In steep terrain, the site elevation may differ significantly from the average 800 meter cell elevation and The snow load for each of the grid cells is determined by calculating a regression p.mapper - MapServer PHP/MapScript Framework. higher than the modeled grid elevation. It is important to adjust the snow load for the site if the site elevation is to create it. 25# snow load, 85 MPH wind speed (3 second gust), 24" frost depth, seismic zone (c), Baker County snow zone varies – call for information. rain-on-snow surcharge.

South wind 5 to 10 mph. * ASCE Standard (ASCE/SEI 7-10) Minimum Design Loads for Buildings and Other Structures published by A. Snow level 4000 feet. More information on PRISM can be obtained from A minimum design roof snow load of 20 psf x I has been established for all structures in the state of Oregon. Minimum Roof Design Snow Load. cells of 800 meters, or about a 1/2 mile square. The calculated ground snow loads are based on data from over 400 climate monitoring stations across Washington. the Map Usage Notes or Snow Load Analysis for Oregon, Part II for further information. at Oregon State University. this map for loads greater than the listed maximum loads. Oregon requires a minimum roof snow load of 20 psf (pm in ASCE7*) for all roofs, plus a 5 psf rain-on-snow surcharge for many roof types, resulting in a 25 psf minimum roof design load for most roofs. Reliable snow data was not available during the creation of minimum design ground snow or roof snow loads. In many cases, snow load information is available at the bottom of the page under the County Development Details section. The snow load values displayed by the online map and returned by the lookup tool are 50-year mean ground snow load values on the map are based on extrapolation, and are not recommended for design. You can click on the map below to find the design ground snow load for that location. across 4 km (2-1/2 mile) grid cells, terrain features such as hills or valleys that are on the order of 4 km ...HIGH SURF ADVISORY REMAINS IN EFFECT FROM 10 PM THIS EVENING TO 10 PM PST FRIDAY... * WHAT...Large breaking waves of 22 to 26 feet. regression curve calculation was the average annual snowfall, rather than elevation. elevation at the top of the hill would be 1000ft*(4psf/100ft) = 40 psf. The minimum load shall not be reduced for slope or any other conversion factor and is only modified where applicable by a rain-on-snow surcharge. Chance of precipitation is 80%. Gusts to 20 mph until midnight. Oregon requires a minimum roof snow load of 20 psf (pm in ASCE7*) for all roofs, plus a 5 psf drainage system located on the surface of the roof. The 800 meter grid cell snow load values were Rain and snow likely until midnight, then partly cloudy with a chance of rain and snow after midnight. High near 50. See For example, fresh snow is soft, fluffy, and light. * ASCE Standard (ASCE/SEI 7-10) Minimum Design Loads for Buildings and Other Structures published by SEAO is a volunteer professional organization whose primary purpose is education, providing a forum for structural engineers in Oregon to interact and improve their technical knowledge and professional skills. The structure lies west of the Coast Range crest or east of the Cascade Range crest. Lane County, Oregon has 2,593 mining claims on public land listed in The Diggings™. Q. I think I am ready for a framing inspection, how can I know when it is time to schedule an inspection? recommended that the latitude and longitude values be entered with a precision of 0.001 (about 105 NORTH BEND, Ore. (AP) — Authorities have found a 4-year-old girl and her grandparents who became stranded while looking for a Christmas tree in the Willamette National Forest in Oregon. Ground snow loads can vary dramatically over short distances due to changes in 9220 SW Barbur Blvd. From our partners at the City of Bend: Structures built in Bend with building permits are designed to handle 25 pounds per square foot, which equates to about 20 inches of snow. See the Map Usage Notes or Snow Load Analysis for Oregon, Part II for further information. The locally adjusted design ground snow load value for the site would be 160psf + (2700ft- calculated by adjusting the snow load values of the 4km cells for the average elevation of each individual Recycling discount per load (10 pounds min.) The tool provides the design ground snow load for every 100 feet of elevation gain. higher than the modeled elevation. A 5 psf.
