The Ingham County Services Committee, a subcommittee of the Board of Commissioners will be hold a public hearing to discuss an alternative analysis report received from the Spicer Group in regards to six options for the Lake Lansing level control structure. The public hearing will take place on Tuesday, February 20 at 6:00 pm at the Ingham County Human Services Building (5303 S. Cedar Street, Lansing).
At the public meeting held on February 6, the Ingham County Services Committee also stated that they would not make any recommendation to the full Board of Commissioners until April 5 to allow for ample time for public comment.
The Lake Lansing water level is maintained by a concrete spillway structure with stop logs as well as a lift gate valve installed in line with a 24-inch drawdown pipe. In accordance with state law, this structure falls under the jurisdiction of Ingham County Board of Commissioners. The Ingham County Board of Commissioner’s has delegated engineering and construction oversight of this project to the Ingham County Drain Commissioner’s Office.
The original structure was constructed in the 1920s and the spillway was reconstructed as part of an improvement project that was completed in the fall of 1976.
During regular inspections completed in 2022, ICDC staff noted that the lift gate valve installed in line with the 24-inch drawdown pipe had become inoperable. These findings were provided in the Lake Lansing Dam Inspection Report, which dates to December 29, 2022. This report recommended the replacement of the control structure, pipe, slide gate, and related support structures.
In June 2023, the Ingham County Board of Commissioners put out a request for proposals seeking professional engineering services to provide an alternative analysis that provide options for repairing the Lake Lansing level control structure. The Spicer Group was awarded this proposal and they have provided their report for six repair options.
This report will be reviewed and discussed at the public hearing on February 20. The full report, as well as other materials, can be found below. For questions, please contact the ICDC at 517.676.8395.
