V. L a k e and Water M anagement 35 Where possible, stormwater flows are routed through vegetation, swales and berms where the absorption of nutrients and the filtration of sediments and organic debris begin. The water is then collected in numerous ponds, marshes, and man-made lakes where it is detained for further filtration before flowing into saltwater estuaries. This detainment also protects against downstream flooding during a heavy rainfall. Both the overflow elevations and the drainage rate out of the ponds are based on the way water naturally behaved on the property prior to development. This maintains the natural groundwater table and preserves the natural “hydro period”, or the amount of time it would take the land to drain naturally. w w w. B o n i t a B a y Re s i d e nt s .c o m
