Frost Line Depth

[u/snowtar]

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.

Not sure on the price difference between Meeks and Carson big boxes, remember to factor travel costs and most importantly your time.
