And the highest elevation in Delaware is 137m at the Pennsylvania border. :)
This location is probably only 5 meters above sea level.

If it is a community center plus swimming pool complex you should make a rough drawing of what it actually looks like. Don't just tag the whole area as a building.

DWG contacted regarding this issue.

I was going to give you a second chance, but now that I saw your comment I am reporting you to the OSM Data Working Group for repeated vandalism.

This is vandalism; fake data is not allowed on OSM. Stop drawing the Darwin fish.

This is vandalism. Stop changing residential areas to parks for Pokemon Go.

Thanks! I was planning on doing this today because I saw the vandalism earlier in the week. I would also recommend combing through the rest of Darwin721's changesets on OsmCha to see if any landuse/park vandalism still remains.

Why is a residential neighborhood marked as a park? And a construction zone in the neighborhood is marked as industrial?

Hi, welcome to OSM!
I fixed up a few things that you added. In the future, please don't mark a residential area as a park. Instead, mark it as a residential landuse. And please don't put parks in private backyards. I also changed the living streets you edited in Florence Tollgate to be semi-private service roads, since living streets only exist in Europe.

Hi again, thanks for responding!
I made a playground since you named one of your points as a Community Playground. But if you think it fits the description of a park better, you can change the playground to a park.

To make a stream, you use the line tool to trace it and then search for stream. It looks like it was already mapped unless there is another stream you are talking about?

And to make a neighborhood, first outline it using the area tool, then search for residential area. You can also give it a name if it has one.

Hi there,
Please do not add fake data such as a park that covers an entire residential neighborhood or nonexistent lakes. If you would like to map out the neighborhood, you can use a landuse=residential tag

Thanks for your addition!

I'm asking you again to please STOP adding fake features for Pokemon Go.
These are not parks, they are communal grassy areas. Please explain where you are getting names for these "parks".
