Please join the Metropolitan Water Reclamation District of Greater Chicago and the City of Markham to celebrate the completion of the Markham Green Alley Project. 

The MWRD will join the City of Markham on Thursday, August 28 at 11 a.m. to celebrate the completion of three green alleys that were converted from impervious pavement using permeable pavers. The alleys are located north of West 159th Street, running east to west, and bounded by Sawyer Avenue to the east and Homan Avenue to the west. Approximately 11,700 square feet was converted to permeable, creating 90,501 gallons of Design Retention Capacity. The MWRD contributed up to $469,000 toward the project. The total construction cost was estimated at $618,597.
