I think you want landuse=residential. building=yes should just be the building outline. If you need help let me know.

You might want to add a tag to FoodLifeLine to describe the business. For example, office=ngo or office=charity. Check wiki.openstreetmap.org for help finding the correct tag

I added a tag to describe the business, healthcare=acupuncture. Also unabbreviated the street name and added add:unit for the unit number.

landuse=forest is for timber harvesting areas. If it just a wood area, then natural=wood

Check out barrier=* for adding a barrier= with an access=emergency. Just add a node in the way where the barrier that prevents through traffic. You can also asdd foot=yes, cycle=yes.

You might be interested in the OpenSidewalk.com initiative being lead by UW. Rather than add sidewalks as tags to the street, sidewalks ar being mapped as separate ways. This allows for better pedestrial routing. Join our meetup if you would like to participate. I'll send a message with an invite.

this looks like eGumbal.com doings. They never have answered a message as far as I know. I sent a message to the email address in on the node, suggestion that they contact their vendor to fix.

Please only add features that can be verified. The footpaths don't belong in OSM when they cross a building.

Do you have some verification that the park you added is not just some green space? Is it listed in the city's directory of parks?

I went ahead and deleted this random untagged way. Remember, when you save and upload an edit, it goes live. If you want to practice editing, take the iD walk through on your browser. http://learnosm.org also has good articles on how to edit OSM.

If you have any questions, just ask.

These are most likely service roads. unclassified are official streets that serve non-residential areas. I went ahead and changed them. If I'm wrong, feel free to correct them. Also, I noticed a number of poorly aligned roads as well as service roads tagged as residential. These was from an import of data many years ago. I changed a few, but could use your help fixing others. Tagging them as residential could cause tourists to get lost.

Thanks for filling in these area. If you are interested, I found these errors using http://tools.geofabrik.de/osmi/ The site also has some other useful tools like map compare. http://tools.geofabrik.de/mc/

I hope you can attend one of our future meetups.

When adding street names, we use the full spelling, no abbreviations. The reason is that software has a hard time un-abbreviating. I updated your edits.

You are created self intersecting polygons when adding in landuse=forest. If you have a section of a polygon that should be excluded, draw the larger area, then draw another area covering the area to be excluded. Then selection both areas click the "+" to create a multiplygon. The excluded area becomes and inner polygon. You can have as many inner polygons as needed. Self intersecting polygons cause rendering and other problems.

The park is already mapped in OSM. Please don't vandalize the work of others.

the tag amenity=school isn't needed on artwork already inside of the school boundary. I removed the tag.

Thanks for updating the bridge.
One minor issue - We use full street names. Abbreviated names are hard for software to un-abbreviate. I went ahead and made the correction.

No problem - Glad to see you contributing

Your building covered the parking lot - I think you intended landuse. I corrected it and added in the building.

Glad to see someone using the StreetComplete app. I think you are the first the in area. Congratulations.

For just practicing - nice start. Just remember, as soon as you upload, your edits are live to the world.
