I wanted to get some advice before I made any drastic changes. While looking around the map, I found this trio of segments that did not match what is on the aerial photograph:
I did drive past this area yesterday, and I found no evidence of the existence of Dola Pl. What I did find was a dirt road leading to one of the large houses seen in the aerial. The part that worries me is the fact that these three roads are named. Should these roads exist somewhere else? My Google searches turned up one result:
I think you’ve done enough research to conclude that the road names were from the plans for what is now named Sunshine Ct. I’d certainly remove the existing Dola Pl and Sunshine Ave as you confirmed that they aren’t there with those names. I’d be inclined to keep one unnamed private road for the driveway there so if routing to or from that house you don’t end up being routed on Sunshine Ct.
