Good one. Wetlands are a gap right now. The closest thing the site shows is the FEMA flood zone for each parcel, which catches some wet ground but not a hidden pond or swamp like yours. I believe US Fish & Wildlife Service publishes a National Wetlands Inventory for the whole country, so checking how much of each parcel is mapped wetland is very doable. Adding it to the list, thanks.
