Protecting Your Waterfront Investment

People prefer clean water and will pay more to live on lakes with better water quality. What you and your neighbors do to sustain or improve water quality will improve resale potential. On the other hand, if water quality is degraded, lower property values could result.

Rain Gardens

Storm water runoff from developed areas increases flooding; carries pollutants from streets, parking lots and even lawns into local streams and lakes; and leads to costly municipal improvements in storm water treatment structures. By reducing storm water runoff, rain gardens can be a valuable part of changing these trends. While an individual rain garden may seem like a small thing, collectively they substantial benefits and can be your personal contribution to clean water.
