Storm water is rain, falling on impervious surfaces and directed down slope by gravity, as "sheet flow". When sheet flow collects in gutters and down spouts, it becomes a point source. Storm water management is the strategy of percolating point sources into ground water. Both sheet flow and point sources can be managed this way, with various strategies.
Uncontrolled storm water discharges have become characteristic of anthropogenic activities which create impervious surfaces. Seasonal fluctuations in precipitation are reflected in ground water table elevations, often creating temporary pools in low elevation areas. These short-term events provide critical habitat for many endangered amphibians who survive by laying their eggs where they won't be consumed buy fish. The overall goal of storm water management is to direct precipitation into the ground water table.
In the spring of 2010, Cape Cod experienced such record levels of ground water, that areas which would normally be dry became flooded as the underground water table rose up in low areas, such as this location between sand dunes. With climate change producing extra precipitation in New England, we have published this booklet to keep our ground water safe by offering suggestions to get roof and driveway runoff into the water table, instead of sending it down our streets.
