Deck Building Specifications on Pacific Coast
I am a member of an RV association that allows year long parking of our 5th wheel. The association is located on the Washington State Pacific coast. The wind zone is 105 mph (3 second gust).
I want to build a detached deck with a roof. The county is requiring 6x6 posts, 4' below grade in 18" dia. concrete, 8' by 12' on center. Snow load is 25 psf. This seems like a bit much. How is this properly sized?
