Why can I not build a Fishing Quay on the coast to the east? (solved, brain fart, pls delete)

EDIT:

Never mind, I am an idiot. Urban tiles must touch other urban tiles. Durrrr.

I don't see a way to delete topics. If a mod sees this, feel free to delete.

Urban districts need to connect to other urban districts, I think. Your only border districts are rural (the resources). You'd have to connect around them to build on that coast.
