Council voted on three water related projects at the June 16 Special Meeting of Council: a feasibility study for remediation work at the Chicken Ladder; a deferment of the High Street water main project; and completing work on the Stocking Lake Access Culvert.
Chicken Lader hardening feasibility study
The Chicken Ladder, which describes the location of the Town’s intake pipe along Holland Creek, suffered erosion after a significant storm in November 2019. Council voted to waive the Town of Ladysmith purchasing policy, and directed the award for hydrologic work to Tetra Tech to conduct the hardening feasibility study of the Chicken Ladder at an estimated cost of $32,000.
Tetra Tech was awarded the contract because of their past work in the area and familiarity with the Chicken Ladder.
Remediation work must be conducted at the site to protect water infrastructure from future high water events. Flooding that occurred in the 2019 storm washed out a paved area adjacent to the dam exposing critical piping. The storm also created a gravel bar which is now influencing flow direction. The site remains vulnerable to another high flow event until remediation work is completed.
The hardening feasibility study will determine a design that will help mitigate the damage from high water events, develop alternative options to protect intake piping while maintaining access for future maintenance and dredging. Those alternatives will be presented for review by Council. The study will also develop a set of design drawings detailing the preferred approach.
High Street water main project deferred
Council approved a recommendation directing staff to defer the High Street water main project to a future year. The project was already put on hold due to the COVID-19 pandemic, and the impact the work would have on local businesses.
Instead, the Town will complete the second phase of the Holland Creek Water Supply Main – connecting the recently installed water main from the trailhead at Mackie Road to the intersection of Mackie Road and Malone Road.
Funds have been redirected toward completing phase two of the Holland Creek water supply main project. Phase two will cost $382,000. The Town will draw $160,000 in funding from the High Street water main project, $24,000 in left over funds from Phase 1 of the Holland Creek water supply main project, and the remaining $198,000 will come from the Water Capital Reserve.
The Town has three phases planned for the Holland Creek water supply main project.
Stocking Lake Access Culvert
Council voted to amend the 2020-2024 Financial Plan to include $50,000 for the Stocking Lake Access Culvert with $25,000 in funds to come from a cost share with the Cowichan Valley Regional District (CVRD), and $25,000 from the Water Capital Reserve.
The access road to Stocking Lake passes over a 1200mm diameter culvert that has failed. The access road is essential to access a primary component of the Town’s water supply. Twin 900mm diameter culverts will replace the old culvert.
High flows from the same 2019 storm event that damaged the Chicken Ladder caused the existing culvert to fail. The access road to Stocking Lake is likely to be completely washed out during the next rainy season if the new culvert is not installed.
Estimated costs for the replacement are $38,800 plus a contingency. Council voted to waive the Town of Ladysmith’s Purchasing Policy, and directed staff to obtain quotes from three contractors to perform the Stocking Lake Access Culvert work.
