Lincolnwood, Illinois is moving to shore up the eroding banks of the North Shore Channel, a 115-year-old man-made waterway whose crumbling shoreline has become an increasing flood threat to homes and roads in the small Cook County village.
The North Shore Channel was built between 1907 and 1910 to divert sewage away from Lake Michigan, running 7.5 miles from Wilmette Harbor south through Evanston, Skokie, and Lincolnwood before connecting to the North Branch of the Chicago River. Its original shoreline structures, including concrete walls, timber cribbing, and riprap, are well past their design life. Decades of water flow, freeze-thaw cycles, and increasingly intense stormwater surges have eaten away at the banks, narrowing the channel's capacity and sending sediment downstream.
Lincolnwood sits at the southern end of the channel, making it the downstream recipient of runoff from three larger communities to the north. With roughly 13,000 residents packed into a largely built-out suburb, there is little buffer between the channel and the houses, streets, and utilities that line it. When banks fail or floods surge, the damage lands directly on residential property.

The timing reflects a broader pattern across the Chicago region. Illinois has experienced major flooding events in 2013, 2017, 2019, and 2023, and federal climate data shows the Midwest receiving significantly more rainfall in extreme events than it did in the mid-20th century. Neighboring communities Skokie and Evanston have undertaken their own shoreline and stormwater projects along the channel in recent years, and the Metropolitan Water Reclamation District of Greater Chicago has been investing in channel improvements as part of its long-running infrastructure program.
For a village with a modest tax base and fiscal pressures common to small Illinois suburbs, a project like this typically depends on outside money. Federal funding from the 2021 Bipartisan Infrastructure Law has opened new channels for exactly this kind of flood mitigation work, and programs through FEMA and the Illinois Department of Natural Resources have helped fund similar projects across the state. Whether Lincolnwood is tapping any of those sources for this project is not clear from the public posting.
The village has posted a bid for the stabilization work seeking contractors, but the full project budget, scope, and timeline are not included in the public summary. Those details are available in the complete bid packet. The project cost and funding sources remain unknown until the village makes additional information public or awards a contract.
