I am amused to learn that PennDOT does in fact refer to the bathtub as such. https://www.pa.gov/agencies/penndot/projects-near-you/district-11-projects/sr-376-a69-bathtub-floodwall-reconstruction-project.html

Got a source for these?

Well, the `sign` node being _on_ the highway way feels a little silly, but it looks correct :)

Features that exist should not be deleted. Add access=no if they are closed.

Please don't do this — railway=abandoned is appropriate when the route still physically exists in the form of tunnels, bridge piers, and the graded way.

Partial revert of 162913083; mistakenly deletes and undeletes some OK geometry because I don't know how conflict resolution works.

Emerald View is pretty interesting in that it combines multiple existing named parks — Olympia, Grandview, and Mt. Washington, plus some others — with a large unimproved wooded space. It would be quite reasonable for the parks to be leisure=park while the whole multipolygon is a nature_reserve. (They're also poorly mapped, I can't actually find Grandview Park.)
