Pervious Pavers in Parking Area

The sandy soil in this area already provides great drainage. The pervious parking lot uses this to its advantage, eliminating runoff off the site for storms up to the 100-year storm event.

Stormwater chambersThis system captures the rooftop stormwater runoff. It allows the water to drain naturally into the sandy soils under it, instead of discharging stormwater runoff to the combined sewer system.

Outlet to combined sewer systemThis connection will allow for the stormwater runoff to be discharged to the sewer system, but only in very heavy storms when the runoff exceeds the capacity of the system.

Note: No stormwater runoff is expected from this site through the 100-year storm event. The system will reduce runoff by 1,000,000 gallons per year.
