My city has been partially "flooded" for over a year so I would love it if this were fixed. Thanks!

There are similar issues in the Ottawa area: http://www.opencyclemap.org/?zoom=11&lat=45.41933&lon=-75.75196&layers=B000
Thank you for looking into this and let me know if help is needed.

I'd like to show another example, Vancouver BC. Annacis island is flooded with water, and the Fraser River is flooded with land. Hope that helps fix this issue.

Fixed. waterway=riverbank was being treated as a linear feature, but also being filled as a polygon. Years and years ago this was true, but people have started using riverbank in (multi)polygons. The stylesheets have been updated and the database reloaded to fix this.

You can see correct rendering here:

It'll take a week or two for all the affected areas to be refreshed, so please be patient. Also, I suspect there will be glitches with the coastline shapefile around New Orleans (the shapefiles are out of date, see #3416 ) so you may find other glitches around the delta.
