Hi folks. I'm planning a 8'x12' shed for our cabin. We are on the high plains and regularly get 50mph winds and 70mph gusts during storms. I'm wondering a couple of things for my construction...
First, we have a 42" frost line but very hard to dig dirt that doesn't seem particularly prone to frost heaves, I'm wondering how deep of footings I really need? On a small shed its really no great crime if it ends up a little off level.
Second, I'm not sure how to best anchor it to the ground. My first thought was to try to auger holes and set the shed on 4x4 posts. That allows me to easily level it and to anchor it. But since the ground is such a pain I'm wondering if mobile home anchors wouldn't be better. Just build it on concrete blocks for level and anchor it down.
What are your thoughts on keeping my shed from blowing to Kansas?
Thanks!
Mark

I did a shed in a high wind area, higher than yours (125 mph in storms, gusts to 135 being reported). I dug holes about 2 feet deep, used 6x6 posts with several 4" spike nails in them to help hold in the concrete, then mixed and poured a bag or two of concrete in each hole. Its been fine.
Augers don't always work that well here, hand dug or a small excavator or backhoe is what we usually do ($45/hr for a small excavator can save a LOT of hand digging!). The ground is tightly packed rock and gravel, with enough larger rocks to throw the auger off center once in the ground.

Sounds like our ground. Did you put the concrete on your posts or under? Not technically supposed to concrete pt posts unless they are rated for burial, but really I wonder if it even matters in shed construction, it's not like I'm making a house to last 100 years
