And lastly, a view from the park position: (Chose this position to match that of the alignment arrows and to lessen strain on the mount)

I have a lot of work ahead of me, I am planning on routing 12g3conductor wire through either garden hose or 1" PVC underground. I want to be able to control the power from inside my home, turn on and off the lights and mount but keep power on for the computer and such. This will all be hooked up to a 20a GFI breaker to my electrical panel, not sure if I will hook it up to the GenBox panel or not, doubtful though lol.
I spoke with our municipality and was advised I do NOT need a permit for any of the work to be done, the recommended that it be footed due to frost but I am not so sure, more work, more money and I have seen plenty of floating decks without any issues at all, but then again, it should be done right.
Frostline is down 48" I want to go down 2' BELOW the frostline, just in case and the footing will be a BigFoot footing: http://www.bigfootsystems.com and will be using 10-12" sonotube for the main pier. Its not easy to get 12" here, I looked everywhere. The deck plans are here: http://db.tt/TZ7GbL2D and the hole is where the pier will go, and the plans do not show extra bracing around the hole, when I will be bracing it.
I will be using the Starizona CGEM Pier plate and the Pier height takes this into consideration. I have offset the Pier inside the pod to 8" to the south to help with Zenith issues.
Let me know what you all think? Should I go higher? It closely mimics what I have now and I never image close to the horizon.

Our frost line is only a few inches here so can't help you there but you do need to get below it with your pier and your plan sounds good there. Call some contractors on the 12" tube. Even if your local stores don't carry it in stock they are bound to be able to get it on special order.

Is it difficult to setup a switch inside the house to control lighting in the dome?
