Hi Matthew,
I like the idea, but which dataset specifically are you referring to? -
https://gisdata-pwcgov.opendata.arcgis.com/datasets/roads ?
To start with, I believe that's the one. I already downloaded a bunch of
shapefiles and didn't necessarily pay attention to which page they came
from, but the file names probably match the URL's.
For starters, I expect to be looking at Road_Edge-shp.zip, Roads-shp.zip
and Sidewalks-shp.zip. (No, I am not going to add roads-as-areas;
Road_Edge would be for reference to possibly help with alignment.)
At face value the license is listed as - custom license. It is not clear
to me that it is public domain based on this description as it
mainly describes liability and "as is" for county government work. US
Federal work is public domain, but states and county governments can vary
on copyright in more restrictive or opaque terms. Making data "open data"
doesn't mean they provide a clear license to its reuse which is unfortunate
and often tough to get clarified in my experience. Could you share how you
determined this to be public domain or US Government data?
As previously stated, via the site's POC ([email protected]):
"Yes, the data is for public domain. There are no restrictions to
attribution, redistribution, and/or alteration."

FYI, pwcgov.org is linked via
https://www.virginia.gov/local-government/, so I am at least reasonably
confident it is legitimately a government site.
"Custom License [snip]"
...or as Drew noted previously (not quoted), "not admissible in court".
I have to assume OSM has a similar disclaimer (I sure hope it does!).
I'm not sure that is even "enforceable" on Public Domain information
TBH, but I don't believe importing into OSM violates that.
Put differently, that's a disclaimer of liability, not, as I read it, an
actual license. (I suspect the use of the "license" there is an artifact
of a page template and not an actual legal license.)
