Canyon Lake Pond Walls Reconstruction

As of 12/02/2022 Staff reviewed submitted bids. Each bidder submitted a base bid and a base bid plus all deduct alternates that were 130-160% of Consultant’s Estimate so the Department has insufficient funding for the project at this time. Amounts on advertising authority indicate sufficient funding. However, approximately $400,000 in 8912 were allocated but not intended to be used and were only available in case payments from GFP were delayed and City needed to pay and get reimbursed by State later. Project will be re-bid at a later date when more funding has been allocated. This project will reconstruct a portion of the Canyon Lake Park ponds and their perimeter walls, replace the short pedestrian bridge, construct a bioswale/detention pond, and improve surrounding amenities like seating and sidewalks. The project aims to improve pedestrian safety and access, provide stability to adjacent turf, enhance fish habitat and water quality, and beautify the park. The primary objective of the project will be to reconstruct the existing West Pond at Canyon Lake Park. The project will replace the existing pond stone wall with a perimeter cast-in-place concrete wall. The overall size of the pond will remain about the same; however, the pond configuration will be modified to improve shoreline access and stabilization. The overall depth of pond will be increase about 2.5 feet. A separate storm water detention pond will be constructed to capture parking area runoff.
