   I'm not an engineer but if I was building it, I would use 2 posts (6x6 notched to accept the double 2x10 beam) spaced 9 feet apart with the beam cantilevering 1 foot past the posts on each side.  An engineer really should make the call though.  The footings are just as important and should be sized according to the bearin capacity of your soil.

   I agree, soil conditions, freeze/thaw can play into it.

   we live in a mild climate, this may not help you

   currently building a house. 14x22 deck. Engineering for house and deck came back with posts not to exceed 7' o.c. hitting concrete pads  (with simpson brackets )no smaller then 2x2x1 witht the bottom no less then 1 foot below native undisturbed soil.
