Maintaining wetlands near developed areas may be the least expensive insurance policy homeowners and business owners can purchase to protect their property. In some cases, depending on soil, geology, and landscape, wetlands will facilitate the percolation of water through the soil, eventually replenishing ground water supplies used for agriculture, industry, and drinking water.
