Title
Binford Drive Drainage Improvement Project - Proposal
History
For many years several residents on the north side of Binford Drive (east of 82nd Avenue) have experienced overland flow of water into their backyards and inside their homes. The property to the north is owned by ComEd for their high tension power lines. There is significant grade change of approximately twenty (20) feet across the property toward the homes causing the overland flow. In 2015 Christopher B. Burke Engineering Ltd. was asked to review the situation and provide a solution to protect the homes.
The result of their investigation identified that a berm and swale could provide the necessary protection up to a 100-year rain event. The berm would be constructed on the ComEd property immediately adjacent to the resident’s north property line. The swale would convey the water within the ComEd property then south, between two homes to Binford Drive.
Proposals were obtained for construction of the berm and swale from three firms. Airy’s Inc. of Tinley Park proposal is for $18,787; Carlin-Moran landscape of Tinley Park proposal is for $31,275; Emerald Site Services of Frankfort proposal is for $19,295. After review, staff recommends accepting the proposal from Airy’s Inc. of Tinley Park.
Because the berm and portion of the swale are proposed to be constructed on ComEd property an easement agreement is required. The ComEd property impacted totals 17,424 square feet. After negotiation with ComEd, the cost of the easement has been established at $30,000.
On October 3, 2016, this item was reviewed and approved by the Public Works Committee and referred to the Board for approval.

Funds for this project are available in the Storm Water capital account 031-6007-470500.
