Not sure it shrank so much as the USGS Hydro database didn't have a strong idea what the shoreline was to start with. Good edit, though!

Switch or substation?

I'm not totally sure I believe the permissions on these footways. If these are privately owned but open to the public on foot, and generally open unless told to leave on a bicycle, that makes more sense. If these are public, highway=path makes more sense with no unusual mode restrictions, with foot=yes and bicycle=yes if bicycles are allowed.

This looks more like a very short residential stub than a living street; also no median means it should just be a short straight line, not a loop.

Was there a particular reason you deleted a neighborhood? It appears the neighborhood name and area is correct.

If that new footway is open to bicycles, it's probably best to mark it as a path. Also noticed you attached the boundary of the park to the road centerline; this is not correct. The park boundary should be placed at the boundary of the park, not the centerline of the street.

Any idea what the name of the park is?

This is vandalism.

Not quite sure footway=sidewalk is appropriate in this spot, since these footways aren't adjacent to a cycleway or street carrying other traffic.

Is this new Griffin Park part of the adjacent Griffin Community Park?

Might doublecheck if you have some overlap on the ways here. highway=unclassified is the same as highway=residential (but more rural or commercial/industrial); might try highway=service for driveways and parking aisles.

Is this just Hall Park perhaps? I do see a smaller playground that could be mapped as well, with the appropriate playground tagging inside the park.

name=pavillion seems unlikely. Maybe building=roof, description=pavilion?

Feel free to continue sidewalks across intersections at the marked or unmarked crosswalk locations, intersecting with the cross street with a node.

Close... might try highway=service instead of highway=unclassified for the driveways and parking aisles.

Name should only be the name, change the name to the old_name key and remove the opening hours and other tags if you know something no longer exists.
