Stormwater Management Commission

MINUTES OF A SCHEDULED MEETING OF THE STORMWATER MANAGEMENT COMMISSION VILLAGE OF NORTHBROOK COOK COUNTY, ILLINOIS May 16, 2013 Village Engineer Paul Kendzior called the meeting to order at 6:30 P.M. in the Second Floor Conference Room at the Public Works Center. Members present: Adele Sturgis, Robert Kaplan, Eugene Chodash, Peter Rosner and Craig Hetue. Chairman Robicsek arrived later. Staff present: Village Engineer Paul Kendzior, and Minute Recorder Colleen Brunner. Minutes: On a motion made and seconded, the March 21, 2013 minutes were approved. Updates on the FY 2012/2013 and FY 2013/2014 Stormwater Management Improvement Projects: A detailed written report was included with the packet. Additional comments are as follows: 1) Sunny Acres Subdivision- Additional work was added to this project on Pamela Lane due to favorable bids received. Lawn and pavement restoration is included. 2) Ridge Road/Lee – The contractor hit an unmarked 6-inch high pressure gas main today. Despite that, work should be completed by July 1st. 3) Shermer Road at UPRR Bridge- The new railroad bridge work should be done by December, 2013. It will then be determined what the road condition is under the bridge, with repair work to follow and reopening the roadway by September 30, 2014. 4) Oak Ave. Storage- The revised plans submitted need further review, and don’t look feasible. 5) Wescott Park Proposed Storage Study- This project would include underground storage with conveyance improvements. 6) Cherry Lane Underpass & Shermer Rd. Overflow Sewer- The Village will need easements from Metra and the Meadow/Cherry Condo Association for this project. Member Sturgis asked if we could incorporate a retaining wall as part of the project, to help the Condominium’s with the flooding issues. Village Engineer Kendzior stated that incorporating a retaining wall is way beyond the approved project scope, but some additional field survey work can be added for a possible FEMA LOMA. In addition Paul Kendzior updated the Commission concerning the April 17-18 storm event. Northbrook received between 3.4 to 4.7-inches of rain. Public works received 83 calls from 4 A.M. to the end of the event. 10 calls for structure flooding, 3 sanitary back-ups and many calls pertaining to street flooding. The recently completed Techny Drain Improvements project performed great with the Woodlands area experiencing less flooding. The Skokie/Dundee intersection flooded as usual because it drains to a poor outlet area that is full of weed and cattails. IDOT maintains this drainage outlet, which is a regional problem and it affects traffic. Member Sturgis suggested we use some of the vacant property nearby as detention. Also add this to the wish list of storm projects and the Village could help pay with underground vaults. Standards for Rain Gardens: Additional comments to the written report entailed concerns of maintenance of the rain garden as the home passes from owner to owner. Member Sturgis would like to see clearer rules and regulations of rain MINUTES OF A SCHEDULED MEETING OF THE STORMWATER MANAGEMENT COMMISSION May 16, 2013 Page |2 gardens with respect to size, depth, soil and placement. After some discussion, the Commission would like the Village to create some guidelines for rain gardens. Perhaps an inspection 2-3 years after installation could be tied to receiving the Village funding. Updates for the MWRDGC Regional Flood Control Projects: The MWRDGC has 2 projects that impact Northbrook. 1) Additional regional detention on the West Fork. The Park District is willing to work with them. 2) Stabilization of the West Fork from Dundee to Cherry. This project has been scaled back to an area by Dundee and Fair Lane. Hear From the Audience: Member Sturgis as an individual regarding her neighborhood behind St. Norbert’s. They experienced flooding and she feels the Village should educate homeowners better about flood protection after a flood. She has concerns with basement depth and building codes. Perhaps pay a fee for a deep basement as this affects the displacement of ground water. Member Robicsek would rather see the building codes changed with future development. Perhaps require larger/better quality sump pumps. No one on the Commission supported sending out letters to educated residents concerning flooding. The code issue should be put on the agenda for a future meeting. New Business: None Next Meeting: To be announced. Adjourn: On a motion made and seconded, the meeting adjourned at 8:20 P.M.
