The storm sewer runoff from the Zone Rec is currently captured in three ways: roof drains, parking area drains, and lawn area drains.

The roof drains combine with a sanitary sewer at Lorain Avenue and are tied into the combined sewer in the street. The parking area drains toward West 65th and is connected to the street sewer. The drain basins in the lawn areas are tied into the southern sewer along I-90.

It will be possible to daylight these storm water collectors and create a surface drainage system leading to rain gardens, bioswales, and detention basins that promote infiltration into the subsoil of the site. This will reduce the overall drainage discharge of the site significantly.
