1.5 inches of top coat

I am hearing on average 1.50 per square foot. .  If the road is 852.50 feet long by 22 feet wide that equates to 18,755 square feet

Times that by 1.50 per square foot and we are in the $27,000 range.  Even if we over pay at $2 per square foot, we are under $40,000?

We need to petition this section of Stark Rd to remain private even with the premise we will put an inch and half top coat?    How can this possibly be rejected?    

This will save all of us a ton of money and keep a betterment charge hanging over us...
