City set to begin next phase of flood protection strategy

Richmond is set to begin its next phase of construction and upgrades to its dike network and flood protection system, as part of its ongoing Flood Protection Management Strategy and Dike Master Planning efforts.
The city is undergoing continual upgrades and improvements to address climate change-induced sea level rise.
Dike improvements begin soon along the north dike, between Nelson Road and the west edge of the train trestle near 21200 River Rd. Approved by city council in the 2020 capital budget, this work will continue to maintain and enhance the city’s current flood protection service levels.
In preparation for this upgrade, staff will plant nearly 1,000 trees to replace 324 that will need to be removed to facilitate ground stabilization and erosion protection work required to reinforce and protect the dike in this location. The trees that need to be removed are largely cottonwoods on the water side of the dike. These trees are being undermined by erosion and present a safety hazard to both road and Fraser River users.
The South Dike raising upgrade—between Gilbert Road and No. 3 Road Pier—is now complete. Upgrades included raising and widening approximately 650 metres of dikes and the construction of an improved multi-use path to enhance the safety and accessibility of pedestrians and cyclists. In addition to these upgrades, 1.6 kilometres of dikes were re-armoured with 11,400 tonnes of foundation stone (rip-rap) as part of the City’s Dike Maintenance Program in 2019. Future dike raising locations include the South Dike between No. 3 Road and Finn Slough.
Richmond’s drainage pump stations continue to be upgraded to accommodate growth and climate change. Construction of Shell Road North Pump Station and No. 7 Road South Pump Station is underway, and construction of Horseshoe Slough Pump Station is nearing completion.
Through capital improvements and investment in preventative maintenance programs, the city is able to proactively prepare and respond to flood related concerns, as its Flood Protection Management Strategy aims to raise dikes and establish a world-class flood protection standard.
The city will continue to engage key stakeholders and the public on climate change, flood protection, and area-specific considerations through the use of social media, open houses, presentations and other platforms.
