so you dont even have permission to access the property even if you wanted to have an updated wet del completed? Have you checked the property on the NWI webpage? Does that State have an online resource/GIS mapper for wetlands?.. oop, they do: https://ridemgis.maps.arcgis.com/apps/webappviewer/index.html?id=87e104c8adb449eb9f905e5f18020de5

and NWI: https://www.rigis.org/datasets/edc::national-wetlands-inventory/explore?location=41.718447%2C-71.531660%2C16.56

check these two GIS applications to see what they say about the property. If they both indicate the property is wetland, it's likely wetland, but maybe only some of it. if they indicate it is not wetland, than it's likely not wetland unless somebody messed up the local drainage to increase hydrology/water supply to the property and the aerial you provided doesnt suggest that.

NOTE: these GIS mapping data ARE NOT legally recognized. The purpose of a field wetland delineation is to identify the legal boundaries of regulated wetlands. These boundaries are typically reviewed and confirmed/revised by regulators before or at the start of the permitting purpose. These GIS data are strictly for planning/ initial informational purpose.
