Hi, and thanks for improving OpenStreetMap! These are apartments rather than houses. One tagging recommendation: for an apartment building, even if it's part of a larger complex, you want to tag it building=apartments. If the entire complex has a name, you can draw a separate area around the complex and tag that landuse=residential and residential=apartments. It's a little confusing, but we want to keep buildings tagged as buildings. I'm going to change the buildings to building=apartments, but feel free to let me know if you have any questions!

What is your justification for upgrading this segment? These are normal city roads, with 35 mph speed limits, and La Cienega distinctly becomes an expressway (higher speed limit, separated, limited-access) south of Obama.

I think that'd be great!

I agree that leisure=park was not correct for Griffith Park, as it is not manicured and so boundary=protected_area is better. However, I don't think tagging the whole park as landuse=forest is the best approach, as it implies the whole park is covered by trees and perhaps used for timber (per osm.wiki/Forest), whereas it's mostly chaparral/scrubs and man-made features like golf courses. After some discussion on the OSMUS slack #tagging channel, I think leisure=nature_reserve is more appropriate, given the definition in osm.wiki/United_States/Public_lands#General_Tagging_Guidelines, so I'm going to change the overall park to that, and try to tag more specific landcovers (natural=scrub, natural=wood, etc) separately at some point. But happy to discuss further if you disagree!

I don't think this change is correct. Based on the surrounding streets, all WWI battles, this street is almost certainly "Marne" as it was before, not "Marine".

Hi! I've been doing some mapping in this area. Could you explain your rationale for changing 842458772 from amenity=school to boundary=school? I'm not sure the boundary tag is appropriate, its only two other uses in CA are both for school districts, not school property.
