Interesting thread. My opinions, and only worth that:
Your contract was with the seller/developer, not with the contractor that did the roadwork. Not really fair for us to badmouth the contractor. I suspect he did what he was told to do for between $5-10,000 and tha's all he could do.
While there may be a reference to 'all-weather road' in law, it's a very open term, and will not stand up in court, and so it really has no meaning. You got a trail of some sort, so I think the terms of the contract were fullfilled legally, and you will be out of luck persuing this. Does your county or state have a minimum code as to the width of an access road to a dwelling? _That_ could possibly be used to get more work done, as your road is rather narrow. About the only way to try to follow this up legally, in my opinion.
It is very naive to think a 3/4 mile road can be built for $10,000. I spent almost that just getting gravel down on my 750 foot road & turn around yard several years ago. No grading at all. While 'a contract is a contract' at some point the buyer needs to be aware of the realities, and it would appear there is about $10,000 worth of road there, so again, in court this would not go too far. You got what you got, which is what you agreed to, which is a cheap road dug in to the place.
Once the road was made, it needs to be maintained. A fresh road needs traffic on it to pack it down (it is unrealistic to expect packing of a private road during construction when it is obviously done for cheap, when common practice is to allow traffic to pack such a private road), and it needs landscaping/ sodding/ seeding to hold the road ditches in place. A good argument can be made that this is _not_ part of the road building, but part of the maintenence of the road. I think the buyer really dropped the ball by not doing this part, not looking it over, not maintaining his road. Again, in court, this would be examined, and there would be a fair amount of fault on the buyer's side for not taking care of the road he was given. This stuck out from the very first message - why were these normal things not done???? Not driving on the road for months after having it freshly built is just a terrible thing....
As others say, all is not lost, you got a pretty good basic trail built in.
It needs the side ditches and some form of crowning, and then about 3x as much gravel hauled onto it, and then seed down the ditches with old straw to keep them from washing away. That might be another $15,000. A road grader could perobably do that from this point, and what I would look to hire. See if he can somehow save the dribble of gravel on top, perhaps he can push it to one side as he works over the ditch & crowning operations.
I think you would do very well if you got the 'developer' to kick in $5000, and you take on the rest. Going through court and all, I think you might come out worse than that, plus lose the lawyer fees. Don't really see you coming out that good either in court or just negociating, but who knows.
I will agree you did not get what you wanted or expected, and it should have been handled better than it was, a better road with real ditches should have been built.
But here you are, and the ball was dropped back in August when you agreed it was a good road and released the money; then you did nothing to maintain the road all winter, didn't even inspect it. Now it's pretty late in the game to get anywhere with that - think the court would say what's up with you?
Time to move on and get a good road built from the trail you have so far. They did a fair job, and you don't need _all_ the expensive stuff folks are mentioning.
You can expect to put $500 into the road every year after it is perfect - just grading the washboards and erosion back onto the crown, and adding gravel now and then. Normal maintenence.
You got messed with for sure, but you kinda set yourself up for it with unrealistic expectations and no follow through on your side.
Not good or right, but how it is, we've all been there, learn from your mistakes and don't dwell on it, enjoy what looks like a wonderful place. Wait until you start building the house, gonna be a dozen more 'little problems' like this that come along. Enjoy the ride.
