Report on Chicago Park District Lagoon & Natural Area Rehabilitation Project, Cook County /

This project is for the ecological rehabilitation of lagoons and natural communities at 24 parks within the Chicago Park District. The development of Chicago's lagoon system began shortly after the State of Illinois created the Chicago Park District in 1869. The lagoons were expanded over the next 50 years into 14 parks and they have become extremely important ecologic, recreation, and historic resources. A variety of factors over the last 140 years have contributed to the current deteriorated condition of the lagoons which require the expenditure of funds for major rehabilitation activities. Age of infrastructure, erosion, and sedimentation were the natural forces at work; however, the lagoons' popularity and lack of comprehensive management plan also contributed. All of the lagoons are eligible to be listed on the National Register of Historic places as major contributing features. Additionally, the lagoons in Columbus, Garfield, Humboldt, Jackson, Lincoln, Sherman and Washington Parks are historic landmarks. The Park District has already invested over $5 million for partial lagoon restoration at Humboldt, Douglas, Sherman, McKinley, Riis and Garfield Parks, and additional work is required.

Responsiveness summary : United States Army Corps of Engineers : Waukegan Harbor, Lake County, Illinois : Section 401 water quality certification for dredging of the Waukegan Harbor approach channel and advanced maintenance area.

The approved project allows the Corps to dredge the Waukegan Harbor approach channel and advanced maintenance area. The area to be dredged lies immediately east of the north breakwater. It is approximately a rectangle 650 feet north and south and 1,400 feet east and west. The advanced maintenance area is a band along the north side of the channel. The approved project is for a 10-year certification, under which the Corps may remove 22,000 to 75,000 cubic yards of sediment per dredging event. The dredging depth is 22 feet and the amount to be dredged is about one foot of sediment. As a condition of the certification, disposal of the dredged sediment in Lake Michigan or the waters of the state cannot occur until the conditions of the certification are met. These conditions, which have been placed on the certification by Illinois EPA, ensure that the project meets state water quality standards and is consistent with the determinations of the Illinois Attorney General's Task Force on asbestos contamination at Illinois Beach State Park.
