Spa on Deck

| I know the usual answer to this question is "speak to a structural engineer." However, I am building a new deck and would like the possibility to add a hot tub in the extended future. We may never install one. I already spoke to a local structural engineering firm and they wanted ~$1,000 just to look at the plans. When I pull the hot tub permit later I'll need a structural engineer to sign off on the plans. I would just hate later if an engineer says, "You could have installed a hot tub if the footer was 1 inch bigger!"
I researched and ran some calculations to come up with footer sizes and I was hoping the community could take a look and let me know the plans look adequate to support a basic Costco tub I found.
Parameters I used:
2000 psf soil bearing capacity
130 psf for the entire deck
Tub details:
7'7" x 7'7"
4100lbs filled
See the plans at the following link:

Thanks. |

| Consider pouring a concrete slab and designing the deck such that you can later cut away and install the hot tub more flush with the deck level. |

| We're required to design to 200lb/sqft for hot tubs or spas on a wood deck. |

| Money-gomery County, Maryland? You are NOT going to get around the red tape associated with having an engineer's stamp. Bite the bullet and pay for the consult now. |

| Thanks for the feedback. Wow 200lb/sqft? Snow country? Yeah I hear you on the engineers stamp. And I have no intention of installing a hot tub without the engineers stamp and proper permits. The big issue I have with paying 750-1000 now is I may never install the tub. Thanks again. |
