I had not been doing any editing in this area. I found the changeset using a tool claled OSMCha (https://osmcha.mapbox.com), which lets people inspect changesets and and helps with finding potentially problematic changes.

I'm not sure what offset problems you were having. The surrounding buildings were traced from Bing, which in this spot has an offset from Maxar of only about 1-2 feet. Any buildings that were in 'green fields' are there because they do not exist anymore. Those should be deleted.

You are correct, that sometimes it is faster to delete and recreate then to fix a badly mapped building. However this causes problems for other mappers who try to follow the history of an object, as well for anyone tracking edits in an area. It's just bad practice.

Hi,
Please do not delete buildings only to redraw them. You can simply change the outline of the building. There is a history component to OSM and deleting and recreating makes this useless. It also creates unnecessary object IDs.
In iD, the editor you are using, you can add nodes to a way and move them around, which you should know from the tutorial. In JOSM you can also create new geometry and replace the way with it.
Please edit ways from now on instead of deleting and redrawing them. Let me know if you have any questions.

Why did you delete these buildings? They appear on all the imagery I can see.

Why did you remove the genus and species tags from many (all?) of these orchards? Is that not useful information?

Back again. Are relation/10214007 and its members supposed to have any meaning? They are not tagged with anything useful but it would seem that they should be inner ways to the Santa Rosa boundary and that the relation should be deleted.

See also nodes 410809594 and 5670179896.
When I fixed the dragging of CA 12 I did not edit the Santa Rosa boundary, so please fix it with your data.

I am also not sure whether the data you are importing is licensed properly. The license given on its ArcGIS page does not state how the data may be used, only that they are not responsible for anything arising from use of the data (http://gisdata-santarosa.opendata.arcgis.com/datasets/city-limits). I'm not sure whether there's a default license that I'm missing but it would be good to know for sure that this is OSM-compatible.

Be careful when doing large edits like this. You dragged nodes 375144970 and 56036760, which were attached to CA 12 and other nodes, damaging a portion of the network.
Please download parent ways when doing large edits in JOSM so you know what you are editing.
I have fixed these two cases (see c76219337) but there may be others. Please check your work and see if anything else was broken.

This was reverted in 75953633.

It is supposed to be a roof part, not a solar panel anyway.
I've added the actual solar panels, see changeset/76116519.

Hi,
Please don't just duplicate nature reserve areas with woods. Woods are intended to describe the landcover outline of a wooded area, not a legal area like a nature preserve. That's why there is a nature preserve tag.
The woods extend far beyond the boundary of the nature preserve, but this makes it appear that they don't and are bounded by the nature preserve. But there's no line in the forest dividing trees on one side of the boundary.

Stop spamming parking nodes. Most of these are already mapped, and the others are incorrect.
Please read my other comments on your previous changesets and respond to them.

Hi,
please do not create bridges where there are none, just to fix the crossing ways errors. Usually, the stream goes underground in what's called a culvert. In iD (the editor you are using), this can be created by splitting the stream at the entrance and exit of the culvert, and selecting the 'Tunnel' option. This will add the tags to show that the waterway goes underneath the road in a tunnel.

Nope. Fixed in changeset #75937431.

Why did you change 'Main Street Gallery' from a clothes store of a different name to a gallery? Both on the same day?
Where are you sourcing the information for all of these POIs? Please provide a source in your changesets.

Hi,
Please stop creating parking nodes along roads like this. `amenity=parking` is not for anywhere someone can park, it is for parking lots and decks.

Hi,
Because this parking aisle is not connected to anything, no router can find it and use it for anything. I have fixed this one.
Please also see my comments on your other changesets.

Hi,
what does the tag `retail=retail_park` mean? It is not documented on the wiki and is only used on highways by you.

Hi,
Please remove these and use correct parking mapping. If you are going to use nodes for parking lots, only one point is needed for each lot. Roadside or parallel parking also has its own tagging.

Hi,
What is Middlesex Canal (relation/10043230) supposed to be? Few of the ways are connected or even flow in the same direction. Is it a historic canal, and if so should the current members be tagged as streams or drains? It doesn't seem to be providing water for irrigation or other uses like a canal does.

I see that the NWI data is public domain, but I can't find an entry on the wiki for this import. It's also not clear that you're importing this data from somewhere.
There's a discussion of an NWI import in Maryland but this is in Florida. Could you please create a wiki page for this import, and follow the guidelines on the wiki (osm.wiki/Import/Guidelines)?
Thanks,
Will
