re: How do I determine if a property is designated “wetlands” in Louisiana?

If there are palmettos growing on it, then it’s a wetland. The reality is that the Army Corps of Engineers must make a determination if the property is not already listed on one of their maps. One of the big tests they use is looking at the types of vegetation growing on the property. If palmettos can (and do) grow on it, it’s a wetland. Thus, if you need a determination, and you don’t want it to be a wetland, kill every palmetto plant you can find and dispose of them completely before the Corps comes out.
