Gewalt Hamilton Associates, Inc. (GHA) provided the Northbrook Park District civil engineering services to design the restoration of the shoreline at Lake Shermerville. The existing sheet wall at Lake Shermerville has moved and is leaning from a plumb position due to pressure from ice and age. On the west side of the Lake, the existing pond shore is heavily eroded.
Proposed shoreline work includes replacement of the sheet pile wall and native shoreline restoration. GHA proposed the use of Rosetta Outcropping stone for areas that will still have a shoreline suitable for pedestrian access. There will also be construction of new pathways and fishing piers.
Lake Shermerville and the neighboring lagoon is considered Waters of the U.S. by the U.S. Army Corps of Engineers (USACE). Shoreline rehabilitation was evaluated and approved by the USACE in a Regional Permit review. Detention was provided within the lake under an MWRD permit in the 1970s, serving over 390 acres of watershed area and it continues to provide regional stormwater management.
The design for this project was completed in early 2021 and construction is scheduled over three years from 2021 to 2023.
