my guess is that this is a MBTA employee bus stop? if so it should have a tag to note that its not a public stop or something...

river polygon here should be set as a culvert

there are more trails here that are missing, its just hard to see via aerial imagery, take a look at the park map for whats missing: https://parks.ny.gov/documents/parks/DevilsHoleTrailMap.pdf

suggest moving the polygon for the water here to connect to just below the dam bottom instead of its current connection to the reservoir polygon and adding a line for the dam water tunnels instead to connect the two water bodies.

pipeline can be extended in both directions, its noted on usgs topo map and most sections of where it is underground is visible from aerial imagery

coffee creek road in this area should be cleaned up its mapped as crossing the river back and forth but it in fact does not and hugs the northern and western side of the river on the mountain side - pretty clear in imagery

road class could be changed to service rd instead of residential for these roads

looks like there is a earthen dam that could be added here for the water body
