After years of talking about it, the go-ahead was given to start the Lake Gregory Regional Park Sitewide Sediment Management Project in 2025 by the San Bernardino County Board of Supervisors at the Tuesday, Nov. 19 meeting.
Supervisors approved awarding the construction contract to Empire Equipment Service, Inc., in the amount of $2.7 million. Empire Equipment Service is a Riverside-based heavy equipment construction company.
A spokesperson for the county Public Works Department said that, during the 2020, 2021 and 2022 storm seasons, heavy amounts of sediment and debris were deposited in Lake Gregory. The Lake Gregory Regional Park Sitewide Sediment Management Project consists of sediment removal, culvert replacements and improvements to the swim beach area.
Removal of accumulated sediments will improve the health of the lake, the spokesperson told the Alpine Mountaineer, as well as the recreational use of the regional park. The project is a priority to effectively manage lake sediments and long-term maintenance of Lake Gregory.
The project consists of two phases. Phase I construction is anticipated to commence in spring 2025 and includes the sediment removal and culvert replacements.
Phase II of the project will occur after the summer of 2025 and consists of the swim beach area improvements. The Department of Public Works (DPW) anticipates bringing the specifications for Phase II of the project for approval, as well as a recommendation to advertise Phase II of the project for formal bids, to supervisors in spring 2025.
Once the dredged material has been dried, plans call for the dirt to be hauled off to the old Camp Switzerland property, located northeast of Lake Gregory.
In order to execute the work within the swim beach and waterpark area, the contractor is responsible to install temporary cofferdam structures or other means to segregate the swim beach and waterpark area to execute the grading and other work in this area.
The contractor is responsible to dewater the existing water from this area to the other side of the cofferdam structure or other means to expose the area to execute the work. During the dewatering, the contractor is responsible to save all fish and wildlife.
