A roads import! 🙂

There's a few lanes that are weird. lanes=7 for a 6 lane road. It's 
weird that some roads have lanes on some parts, not all (e.g. "Hollywood 
Street"). Maybe try to make it consistant? JOSM validator has found a 
handful of topology errors. There's ~100 examples of roads that aren't 
connected properly (nodes on top of each other, but not connected).

You seem to be defaulting to "highway=residential" a lot (e.g. if you 
dohn;t know another, or turning 'Gravel' into 'highway=residential 
surface=gravel'). I don't know a lot about tagging in the USA, but isn't 
there (wasn't there) some problem with the TIGER data using residential 
too much?

Can you link to your discussion with the local community, how/where did 
that happen?

The link the tasking manager project doesn't work.

I'm a little unclear about one big question: What are you doing with the 
existing data in OSM? Existing OSM data seems to have nearly identical 
locations to this new data. You're just going to update existing OSM 
data? Do you know how much existing OSM data needs to be updated?
