Alternatives For Storm Water Holding Ponds

"Large regional ponds -- dry most of the time -- have been used by county engineers for more than a decade to contain rain runoff and control erosion and water pollution...The aim has been to prevent runoff from new housing developments from washing soil downstream and carrying pollution into waterways and eventually into the Chesapeake Bay. But the regional ponds often require streambeds to be cleared of trees, dammed with earth berms,equipped with concrete drainage structures and then served with access roads so the ponds can be maintained."
