Wind, Snow and Seismic Zones for Clallam County

Area	Wind Speed	Wind Exposure	Average Snow Load (≤600' elev)	Seismic Design Category
	ASCE 7-16 2018 IBC, 2018 IRC		GROUND
Diamond Point	110 MPH	C/(D**)	25 PSF	D2
Sequim	110 MPH	C/(D**)	25 PSF	D2
Port Angeles (Blue Mtn. - Joyce / Lake Crescent)	110 MPH	C/(D**)	25 PSF	D, E
Lake Dawn/Foothills	110 MPH	C	*	D2
Pillar Point	120 MPH	C/(D**)	25 PSF	D2
Beaver	120 MPH	C	30 PSF	D2
Clallam Bay/Sekiu	120 MPH	C/(D**)	25 PSF	D2
Forks	120 MPH	C	30 PSF	D2
La Push	130 MPH	C/(D**)	25 PSF	D2

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.
