one small tip - we don't abbr. street names as software has a hard time unabbreviating names.

The library needs a tag, amenity=library so it is properly categorized. Also - even though the imagery is poor, try to capture the building foot print a best a possible and then square the outline when done. Makes it look much better when rendered.

I noticed that the house address is different than the street. According to King County records, it should match your house so I updated the street names - Feel free to correct if KC is wrong. Also changed the name of the street across from 245th Pl NE to Northeast 1st Court.

Street names should be expanded since abbreviated names are hard to un-abbreviate. Also I added a tag amenity=dentist to describe the building.

We spell out street name fully instead of leaving them abbr. Software has a hard time abbreviating names so we don't use abbreviated street name. Also - you might want to add a tag to describe the business, such as office=marketing or even office=seo. see https://taginfo.openstreetmap.org/keys/office#values for more values being used.

I tried to fix your edits - removed the duplicate building, corrected some and removed other non standard tags. Please read and follow the osm.wiki when adding to OSM.

The address should go on the point - I added it.

I went ahead and changed the street to 120th Court Southeast. In OSM we use the full spelling since software has a hard time UN-abbreviating words.

I merged the existing node for the fire station with the new building you added.

We use the full street name in OSM, also location is in the middle of the parking lot. I correct it - but only guessed on location based on address.

Wow - is that actually their name, (mend)bicycles? That's a great name.

Try not to draw the building over the path, unless there is an overhang. That can confuse routers. It looks like someone used a different imagery to add the paths, you used Bing which may have an offset.

I was looking at the tags I thought the "new user" had added and was impressed until I saw that you were the one that added them. Thanks - and nice job. Too bad we can't get eGumball to edit properly.

Does the car wash have a name?

Can you give a tag that describes the Camano Island Cattle Company? Just a name is kind of lonely. Is it a restaurant, amenity=restaurant? Let me know if you need help figuring out what tag to add.

We don't use descriptive names. It's okay to add a note tag with descriptive info. Can you Fix the two speed signs you added?

Does the Ghost Note Coffee actually charge a fee for internet access?

I fixed the address, it should be addr:unit=A and added a tag, office=mortgage to describe the type of business. Feel free to correct if I guessed wrong. See https://taginfo.openstreetmap.org/keys/office#values for all possible values being used for office.

RV parks are tagged as tourism=caravan_site. OSM started in the UK so we use British English. I went ahead and changed the node. I also placed it over one of the buildings, but not sure which one is the office.

I think you want to tag it as leisure=swimming_pool. See leisure=swimming_pool for more details on tagging pools.
