River Road West - Flood Management Strategy

Share on Facebook Share on Twitter Share on Linkedin Email this link

The River Road West dike is an important corridor from 34th Street to Ashbury Place. The dike protects Ladner and adjoining agricultural lands from flooding. In response to climate change and the need to address future sea level rise, Delta is developing a Flood Management Strategy for the River Road West area.

Important: These conceptual designs were developed in an effort to avoid additional private property requirements by ensuring the proposed flood protection improvements would be undertaken within existing road dedications and statutory rights of way.

Given the costly nature of this project, significant Federal & Provincial funding assistance will be required to move the final design forward. However, it is important to have a design ready, should funding become available.

This Flood Management Strategy will strive to maintain and enhance this unique and vibrant community. Some of the key components of the strategy include the following:

  1. Long term flood protection which addresses rising sea levels due to climate change
  2. Traffic calming in the form of raised intersections to reduce speeding on River Road West
  3. Provision for vehicle access and resident parking on the dike roadway
  4. A continuous multi-use pathway allowing connections to Westham Island Bridge and Brunswick Point
  5. Improved resident access through use of raised intersections to allow for more gradual transition to dike roadway
  6. Consolidating access points by reducing the number of driveways
  7. Raise dike by approximately 0.6m by 2050 with provisions to raise the dike a further 0.6m by 2100

Due to the recent restrictions related to COVID-19 and to ensure the heath and safety of the community, the City of Delta has created this online community engagement tool. Here, impacted residents will be able to review and provide input on the suggested dike/road improvement option and make suggestions, add comments, or raise concerns that you would like the project team to consider.

Below you will find five different dike sections that will provide you with an idea of what the proposed dike improvements could look like. Please take your time to review this information and complete the survey questions below. Your input will help to make this consultation a success!




Segment 1 - Ashbury Place to 41B Street

Segment #1 - Ashbury Place to 41B Street (shaded in yellow above)


  • Two travel lanes with vegetated retaining walls for grade separation to dike
  • Multi-use path, one way access lane and parking on top of the dike
  • Raise road moderately at intersections to facilitate easier grades to the top of the dike using ramps
  • Vehicles accessing the lane on the dike require crossing the multi-use pathway at select locations


Proposed Dike Cross Section Concept - Ashbury Place to 41B Street




One-Way Traffic Flow With Parallel Parking On-top of Dike








Raised Intersections to Top of Dike

  • Pedestrian stairs that lead from the intersection to the top of dike
  • Vehicle ramps for access to and from the top of the dike
  • Vegetated retaining walls for grade separation
  • Raised road moderately at intersections to facilitate easier grade changes
  • Safe and continued access for residential and Industrial properties
