If not, how about building a small berm on your side of the road to again 'deflect' the runoff
Please make sure that you don't deflect the water onto someone else's property, though, as it could possibly cause you some liability issues depending on your local ordinances.

Great idea
As dyzzypyxxy said, though, the town council may be your best bet. If you cannot get any satisfaction from them, then slowing the water down (you can also use a creative planting scheme to slow water) may be your best option.
Could a french drain at the top of your hill be of help, perhaps?
