Thanks to all for the guidance.
I've set up a Wiki page, as well as added this project to the import
catalog:
https://wiki.openstreetmap.org/wiki/Import/Catalogue/Fayetteville_Building_Footprints
In regards to the building classification, building=detached seems weird
to me as well, but it appears to be what the OSM guidelines call for:
https://wiki.openstreetmap.org/wiki/Tag:building%3Ddetached, sums this
up to be:
"A free-standing residential building usually housing a single-family.
Known as a /single-family home/ in the United States, a /single-detached
dwelling/ in Canada, and a /separate house/ in New Zealand.
If the building shares a wall with another building (forming half of a
semi-detached pair, or one of a row of terraced houses) then it should
be rather tagged building
<https://wiki.openstreetmap.org/wiki/Key:building>=house
<https://wiki.openstreetmap.org/wiki/Tag:building%3Dhouse>."
It seems like the typical house in the US is "detached", and the things
we call townhomes/rowhomes are "house" in OSM? It's a bit strange to me
as well, but I understand that these are likely the more global terms
for these types of structures.
In regards to the imagery I'm using to check the footprints, it is the
"Fayetteville Current Imagery". This is our most current imagery, flown
about a year ago:

As Jon noted, you are required to create a import page on the wiki to
describe your planned import. You should also announce it on the
talk-us mailing list. You might also want to join our Slack [1]
import channel. But make sure you read the import guidelines [2].
If you can involve local mappers, I'd suggest using the Tasking
Manager [3], to break the work into small chunks. We used voting
districts to breakup Kirkland, Washington Building and Addresses [4]
import. voting districts are nicely sized to import.
In all of our imports, we took the opportunity to teach people how to
use JOSM to import the data. One of the nice features is to use the
Address Tags Validator Map Paint Style. It colorizes the addr:street
object the same as the highway= road. If the two match, then they will
be the same color. It is a quick and easy way to spot differences. We
identified a number of errors in a local counties gis data.
Let me know if there is anything I can help you with. We are getting
ready to announce another import in Washington State so this is all
fresh in my mind. (It goes quickly :-)

Hi Mike,
Great idea!
I used to live in Fayetteville and now I'm out in Los Angles
helping out with the building import here.
I agree with Frederik and Clifford about trying to get someone to
help you. We've used our import to build some community around the
import. It's a bit tedious so we've only hand a handful of events.
That said, your address and building attributes would go a long
way in improving the data itself.
Maybe, though, the Fayetteville Flyer could get involved? Or
possibly the NW Democrat-Gazette? If they want a free way to make
more maps for their news stories this could provide an incentive
to improve the data.
In regards to the data/tagging, it looks like some of these houses
are tagged as building=detached. I think it'd be more appropriate
to tag them building=house. For duplexes building=residential. And
for apartments/condos usually building=apartments. The default is
building=yes. Are there possibly more data tags you could add that
would be of value? Maybe when the house was built, a unique
property ID number or unit count?
I'd also suggest creating a page on wiki.openstreetmap.org
<http://wiki.openstreetmap.org> to detail the data and the import.
Here's a link to ours:
http://wiki.openstreetmap.org/wiki/Los_Angeles,_California/Buildings_Import
<http://wiki.openstreetmap.org/wiki/Los_Angeles,_California/Buildings_Import>
And finally, how did the city collect the data and how old is it?
Sometimes the satellite imagery is more up-to-date than the data.
You may also be able to tie into more up to date imagery collected
by the city since that would likely fall into the public domain
under the Arkansas Public Records Act. For instance, the tile
server here looks to have pretty good imagery (I'm not sure on the
age):
http://gis2.accessfayetteville.org/faygis/rest/services/BaseMaps/Aerial_Current_WGS84/MapServer/tile/8/678760/250154
<http://gis2.accessfayetteville.org/faygis/rest/services/BaseMaps/Aerial_Current_WGS84/MapServer/tile/8/678760/250154>
I'm happy to connect off-list if you have any questions or need an
introduction with the Flyer/DemGaz folk.
cheers,
Jon

If that was possible then you'd have a larger group who
feel responsible
for the data set and it wouldn't be your responsibility
alone. In the
best outcome, this could even help invigorate local
mapping efforts.
+1 to Frederik's suggestion.
