Soil bearing pressure: 1500 PSF
Frost depth: 12 inch minimum
* For elevations greater than 600 ft above sea level, snow load = elevation x 0.04.
Example: 800 ft elevation = (800 x 0.04 = 32 PSF snow load).
Roof snow load shall not be reduced below 30 PSF in Beaver, Forks or Neah Bay and not below 25 PSF for the remainder of Clallam County.
** All areas within 600 feet of the marine shoreline are exposure "D", and/or a body of water 5000 feet (.95 of a mile) across, are exposure D.
