Lots of interesting thoughts & opinions. I have a couple questions. Is the road shown as easements on the property deeds?
You state 5 owners, 200 ft frontage each. Does the road run down the center of each property, or is there a sixth owner for the 1000 ft frontage on the other side?
Don't know if it is state law or just county policy, but here there is a process to get the county or township to take over a private roadway.
1- each abutting property owner donates by quit claim deed a strip 33 ft wide to county or township. This makes a 66 ft, or 4 rod wide, public right of way. (see below)
2- property owners improve the road at their own expense, including surface elevation above abutting property, drainage ditches, culverts, tree removal, etc. If a dead end, must provide adequate space at end for grader, snow plow, school bus, etc to turn around without stopping & backing. Any utility line such as power & phone moving at owners expense.
3- owners maintain the road for 1 year, & warrant that the road is in good condition at end of that year.
4- county or township then accepts road & does future grading, gravel adding, & snow plowing as needed.
Note- in the case of 200 ft frontage, each owner on both sides donates 6600 (200x33)sq ft, or .15 acre of land. It gets complicated & expensive.
