East of Harms Regional Stormwater Project
July 29, 2015 -- The intersection of Harms Road and Wilmette Road is closed for installation of a large junction chamber. No access is possible through the intersection. Reopening is scheduled for September 4, 2015. Local traffic is being routed on Ferndale Road and Heatherfield Drive. Regional detour between Glenview Road and East Lake Avenue continues to be Wagner Road.
May 22, 2015 -- The east and west legs of Glenview Road at the intersection of Harms Road are reopened to traffic.
April 13, 2015 -- The east and north legs of the Glenview Road/Harms Road intersection and Harms Road from Glenview Road to Wilmette Avenue are closed to traffic to facilitate storm sewer installation and connection work.
August 5, 2014 -- The East of Harms regional stormwater project was moved forward after the Village Board of Trustees awarded two contracts to get the work started.
March 20, 2014 -- An informational project meeting on the planned East of Harms regional stormwater project was held. Click here to view the meeting invitation and here to view the movie presented at the meeting.
February 18, 2014 -- The Village Board of Trustees approved an Intergovernmental Agreement with the Metropolitan Water Reclamation District of Greater Chicago that provides up to $6 million in cost-sharing funds for the construction of this regional project.
The storm sewers in the areas east of Harms Road in Glenview are directly impacted by the elevation of water flowing in the Main Stem of the North Branch of the Chicago River (the "River"). The River is located in the Cook County Forest Preserve District to the west. When the River reaches flood stage, the Village storm sewer connections are as much as 10 feet underwater. The impacts from this include regional river water flowing back into the local system and the inability of the local storm sewers to drain at all until the river recedes. Impacted areas see impassible roadways making some properties inaccessible and numerous private property flooding issues.
Prior MWRD study
The Metropolitan Water Reclamation District of Greater Chicago (MWRD) commissioned a study in 2008 to study the entire North Branch of the Chicago River watershed. The results of the study, published in January 2011, can be found at:
A project titled "MS-14" was conceptually developed to provide 2,800 acre-feet of new regional stormwater detention upstream of the impacted areas in Glenview. Ultimately, land ownership and a challenging cost-benefit has prohibited that project from moving forward with more engineering since concept approval by the MWRD Board of Commissioners.
New MWRD "Phase II Funding"
On April 18, 2013, the MWRD Board of Commissioners approved a new "Phase II" funding for locally developed projects to provide regional benefits. The call for projects letter was sent on May 9, 2013.
Upon notification of the call for projects, and in an attempt to bring a "constructable" project closer to fruition, the Village directed their engineering consultants to complete final construction plans and specifications on a local project to benefit the regional flooding impacts. The project plans will include:
- Backflow prevention on the three sewer outfalls to the River – this will prevent the River from backing up into the local storm sewer system;
- Two new lift stations will be installed – this will allow the local storm sewers to continue discharging until the River recedes; and,
- New storm sewer conveyance and detention piping will be installed.
The goal of the project, upon construction, is to reestablish the level of service for the existing storm sewer system. The project was summarized in the Village's May 28, 2013 submittal to MWRD.
An updated letter was mailed to all area residents on June 28, 2013.
