Chilliwack riprap project wraps up

Chilliwack riprap project wraps up
CITY OF CHILLIWACK — Crews have completed work on a riprap project that will strengthen the resilience of riverbanks on the Fraser River in Chilliwack, B.C.

CHILLIWACK, B.C. — Chilliwack is ready to weather future stormy waters.

Approximately 210 metres of rock armouring, also known as “riprap,” has been installed along the Fraser River just downstream from the Camp Hope Intake, completing a multi-year, multi-phase Fraser River erosion protection project. As part of Chilliwack’s Flood Response Plan, this rock armouring stabilizes the riverbank to protect it from heavy river flows.

The 485-metre section of riverbank just downstream from the Camp Hope Intake was identified for erosion protection in 2019. That same year, as the first phase of this project, rock armouring was completed along 275 of the 485 metres. Construction on phase two began early this year, following agency approvals for the Provincial Water Sustainability Act, Dike Maintenance Act and Federal Fisheries and Oceans.

“Chilliwack has an extensive diking network along the Fraser and Vedder River systems,” said Mayor Ken Popove in a statement. “Our dikes are inspected and maintained on a regular basis, as part of the city’s flood response plans, and this long-planned riprap is a welcome addition to the infrastructure that keeps our community safe.”

The $918,000 phase two project was funded in part through a $750,000 provincial grant from the Community Emergency Preparedness Fund, provided by the BC Ministry of Public Safety and Solicitor General and administered by the Union of BC Municipalities.

The completed project is expected to increase the stability of the adjacent diking.
