If it is a "stream", you will have problems with the feds putting concrete in any stream without proper permits... be careful
Yes there is that element to convolute matters. I'm going to speak with the county judge before I do anything. 10 years ago there were talks of cost sharing with the county and landowners to build a "bridge" of some sort. I couldn't get everyone on board at the time and it fell by the way side. Of course, new judge now so will start back at zero.
