Communities may implement low impact development techniques to reduce flows of stormwater into the collection system. This includes:
*constructing new and renovated streets, parking lots and sidewalks with interlocking stones, permeable paving and pervious concrete
*installing green roofs on buildings
*installing bioretention systems, also called rain gardens, in landscaped areas
*installing rainwater harvesting equipment to collect runoff from building roofs during wet weather for irrigating landscapes and gardens during dry weather
*implementing graywater collection and use on site to reduce sewage discharges at all times
