“As a real estate agent, I have advised clients and potential clients seeking to buy or sell parcels of land to do due diligence. If there is a recurring mud puddle it may be declared a wetland and greatly devalue the property...”
This issue was addressed by the USSC in Rampanos v US. Also in SWANCC v US.
In it’s most simple terms, the USSC said that puddles and streams are not navigable waters. The issue of so-called wetlands is irrelevant under laws passed by congress.
That was in 2006. The advising was mostly in the 1980s and 90s, when the green mafia was running wild, well before the USSC decision.
The greenies are still likely to claim that some endangered critter or plant inhabits your property, though.
