Title
Mason Lane Drainage Investigation - Proposal
History
Earlier this summer several complaints were received from residents of the Heritage subdivision near 143rd Street and Concord Drive regarding rear yard and street flooding. The area north of 143rd Street drains south to the privately owned wetlands north and east of Mason Lane in the Georgian Woods subdivision, Villas subdivision, and Georgian subdivision, and then continues through the private pond in the Evergreen Townhomes subdivision and finally into Schussler Pond (public) in Fairway subdivision.
Staffs investigation showed that the associated storm sewers were not draining properly. A review of the drainage area identified several issues contributing to the problem, including the culvert under 143rd Street which was found to be filled with silt. The culvert pipe under 143rd Street was thoroughly cleaned by Public Works staff to ensure the water could drain from north to south. However, further investigation revealed that the receiving wetland adjacent to Mason Lane was preventing the storm sewers from draining properly, creating the silting condition.
To remedy the situation and improve drainage throughout all of the impacted areas Christopher Burke Engineering, Ltd. (CBBEL) of Rosemont, Illinois was asked to provide a proposal for the evaluation of the wetland to determine potential solutions. The proposal provided by CBBEL includes field surveying, further drainage investigation, and a summary evaluation. Once completed, staff will determine options to move forward working with the owners of the privately maintained wetlands.
On October 3, 2016, this item was reviewed and approved by the Public Works Committee and referrred to the Board for approval.
