Meeting in regular session on February 21, 2019, the Board awarded Contract 18-19.013 Willowbrook Lake Dam Reconstruction Project to Panhandle Grading and Paving, Inc. Willowbrook Lake, located in District 5, serves as a stormwater retention pond for the areas south of Kingsfield Road, north of Ten Mile Road, east of US 29, and west of Chemstrand Road.
The dam structure at Willowbrook Lake was severely damaged during the April 2014 Storm Event, which compromised Chemstrand Road, a major corridor to industries north of Nine Mile Road. To ensure that the infrastructure along Chemstrand Road would not be compromised in the future, the County agreed to obtain drainage easements over the area and rebuild the dam. The Board approved easements for the project on July 7, 2015 and August 1, 2019.
The Public purpose of this project is to reconstruct the dam to provide stormwater treatment for the area, protection of Chemstrand Road, and protection of downstream properties. The lake behind the dam will serve as a stormwater treatment system for nearly one square mile lying between Chemstrand Road, US 29, Ten Mile Road, and Kingsfield Road. All environmental permits for the project have been received and construction is underway.
This recommendation is to request reallocation of funds, in the amount of $92,896, from project funding to be determined to the Willowbrook Lake Dam Reconstruction Project, which will be utilized for construction engineering and inspection services ($35,000) to ensure the specialized clay core of the new dam is constructed per the geotechnical specifications, and will also provide a 5% contingency allowance for any unforeseen changes during construction ($57,896) without causing delay.
Total Spent on Project to Date: $1,367,101.29.
