I live in a subdivision that borders a small private lake that is mostly surrounded by cattails, then leads to higher ground where the homesites are. Most of the people that live on the lake have a docks that access the lake by going through the cattail marsh areas without destroying those areas. A new neighbor had recently leveled the cattail marsh area in front of his home (about 50 ft x 150 ft). and I assume his next step would be to make a beach in front of his home. Is this legal?? What about laws protecting wetlands?
