As predicted, higher-than-normal freshet flows this spring caused changes to Mission Creek that require repair and refinement of the floodplain and fish habitat restoration work completed in 2016. The Mission Creek Greenway dike on the south side of the creek between Casorso Road and Gordon Drive will remain open while work is undertaken next week.
Work crews and heavy equipment will be on site from November 14 - 21. Greenway users should avoid the work area, watch for dump trucks, construction crews and equipment, and respect the flaggers and signage to ensure the safety of all workers and the public.
“Phase 1 was designed and built recognizing there would be ongoing changes to the restoration components resulting from high freshet flows,” explains Mission Creek Restoration Initiative project coordinator Steve Matthews. “As a result, plans to adaptively manage the site over time in response to these changes were developed prior to project implementation. These upcoming works will involve minor adjustments to ensure the long-term health and productivity of the creek.”
Phase-1 project engineer Don Dobson concurs, saying that, “While the works generally performed as designed, this spring’s well-above-average runoff caused changes that need attention. We’ll go in to maintain the four meander notches that were built to provide fish spawning and rearing habitat for kokanee and rainbow trout by rebuilding and reinforcing berms along the old dike footprint to minimize erosion and reduce overflow into the side channel and floodplain.”
All activities will be undertaken as outlined in the project’s Adaptive Management Plan, and according to the requirements specified in all applicable legislation.
