Suggestions:

• Landscape with a rain garden to provide on-lot detention, filtering of rainwater, and groundwater recharge.
• Disconnect the gutters and downspouts from roofs and direct the flow to a rain garden.
• Retain rooftop runoff in a rain barrel for later on-lot use in lawn and garden watering.
• Combine the rain gardens with grassed swales to replace a curb-and-gutter system.
• Use permeable pavers for walkways and parking areas.
