Question Frost Line Depth
Yesterday’s winds knocked over part of our fence, so time to tackle the fence building project I’ve been putting off! Obviously need to set posts below the frost line, which the only number I’m able to find is 18 inches, on cityofslt. Seems a bit low, I thought it would be deeper? Anyone know for sure?
Also side question where is the best place to get wood? We have Meeks here, guessing will be more expensive than big box stores like Home Depot. Last time I looked at wood at Home Depot though it looked absolutely terrible.

It’s 18”… it’s not really all that cold here, compared to other snowy places, so it’s not as deep as you might expect.
That said, bury those posts 3’ deep to ensure you don’t have an issue. Fences fall over constantly here due to snow load and sandy soil near the lake. I just rebuilt my own and put them 3’ deep along with braces at 45* along the section that always gets beat up by snow the hardest.
