You might look into what's being done in Sweden then, here there are
municipality networks who dig up the streets and does fiber to the
individual house in "suburbia" (you have to trench your own land though,
4dm deep, 1-2dm wide, they only dig in the street put down the pipe in
your trench).
Common cost for the house owner to get this done is in the 2-4kUSD range
per house, then you can choose between multiple ISPs to purchase your bw
from. 100/100 (symmetric speed) seems to cost 40 USD per month, 10/10 is
5-10 USD/month cheaper.
I've been trying to run the text thru google translate, but the web magic
seems to prohibit this from working.
If someone can figure it out better than me, the URL is here (in swedish):

I'd look more to what they're doing in Rochester, NY:
http://rocwiki.org/Sewer_Fiber_Optic_Network
Run it in the sewers. The sewer system runs to every building and
household in the municipality. No need to re-trench anything.
