Work begins on $1.4 million Grayslake flood mitigation project

Work is underway on a $1.4 million project intended to improve drainage for 84 Grayslake homes and alleviate standing floodwater on several roads, including Washington and Lake streets.

The Haryan Farm Drainage System Improvement Project includes the construction of a 30-inch storm sewer pipe connecting the Haryan Farm North Pond to the existing detention pond northwest of Lake and Washington streets.

A new storm sewer will be installed to extend into the Grayslake Metra station campus, which will limit the amount of excess standing water in the subdivision ponds.

After the floods of 2017, the Haryan Farm and West Trail subdivision ponds saw an extended period of high-water levels. Since then, excess standing water and pond overflow in the area has been an ongoing issue.

The project is partially funded by a grant from the Illinois Department of Commerce and Economic Opportunity.
