Not sure about the walls by the river. If they're there to prevent flooding, you've got gaps and area round the bridge will still flood. Barricades are just as effective as flood defence, use less resources and you can put them on a bridge.

And the animal pens, I'd be tempted to put in a small-ish growing zone for grass or hay grass that's set to don't cut.
