Ideally, these should be shifted to the border of the land use, rather
than another location within the right of way.
Exactly. As a technical matter, in almost all cases of a public roads in
the US, if you look at the tract map, you will see a permanent dedication
of an easement/right-of-way for the road, and that land cannot be built on.
For the most part, these ROWs are even wider than the road itself has been
built on. The residential and commercial landuse ways should definitely
extend no further than the sidewalk in this vast majority of the scenarios.
Even if it were possible for someone to build in the middle of a street,
unless they actually have done so, it shouldn't be mapped that way, since
we aim to map what we see now, not duplicate a zoning map of what could be.
