Villa Park Sediment Pond Stormwater Improvements
n the winter of 2022-23, the City will make improvements to Sediment Pond (the northern-most pond) in Villa Park. This pond was constructed in 1985 as a flood reduction and water quality project for Lake McCarrons. The pond captures stormwater from approximately 1,023 acres, and allows sediment to drop out before the water outlets and flows through a series of wetlands towards Lake McCarrons. The Capitol Region Watershed District also uses Sediment Pond for monitoring purposes to collect water quality and flow data.
The proposed improvements will include replacing the outlet on the SE side of the pond near the walking bridge, tree management, and dredging the pond of accumulated sediment. Currently, there is approximately 1,600 cubic-yards (160 dump truck loads) of sediment that needs to be removed from the NW end of the pond where the stormwater enters.
In the late summer of 2022, the City will contract with a company to trap turtles that use Sediment Pond as a location to hibernate over the winter. Turtles that are trapped will be relocated to the wetlands downstream of Sediment Pond.
The work to the pond will help protect the water quality of the downstream wetlands and Lake McCarrons.
Turtle Trapping & Relocation
The City will be trapping turtles in Sediment Pond and relocating them to the wetland cells to the south. Traps will be set starting Monday, August 8, and will be checked daily throughout August and into fall. The traps will be baited Monday through Friday each week, and they will not be set out over the weekends. By trapping the turtles, we can relocate them to a safe location where they can burrow and hibernate over winter.
Turtle Trapping - 8/8/22 thru 10/28/22 (Complete)
Turtle trapping and relocation in Villa Park.
Dewatering: 1/27-1/31 (Complete)
Draw down north pond over two days 1/27 & 1/28. Then immediately begin dewatering the south pond over two days 1/30 & 1/31.
Dredging of the pond has been postponed to the winter of 2023/2024 or 2024/2025, due to the weather this past winter.
95% of the utility work is complete as of June 1, 2023. The remaining work consists of installing a weir in the new outlet structure on the south side of the pond. Currently, the water level of the pond is lower due to the fact that the weir hasn’t been installed. Manufacturing of the weir caused the major delay, and the weir will be installed by June 30, 2023. The water level will rise back to its normal elevation after the weir is installed and Roseville gets some precipitation.
Note: All work is weather dependent and subject to change.
