Marine Drive Stabilization Project
The City of White Rock is performing retaining wall stabilization and road improvement works on Marine Drive between Johnston Road and Cypress Street. The work includes installation of micropiles, reconstruction of the roadway, curb and sidewalk on Marine Drive between Johnston Road and Cypress Street.
Target Project Timeline
Oct. 2020 - Jan. 2021
Work will take place Mon. - Fri. 7:30 a.m. - 7 p.m. and Sat. 9:30 a.m. - 5 p.m.
Protecting the slope of Marine Drive
An investigation of the metal bin walls located on the slope below Marine Drive was included in the scope of this project.
The project’s geotechnical engineer recommended that the bin walls be strengthened within five years. Future failure of the bin walls could result in materials sliding down the slope onto the railway and Promenade below.
City Council awarded $500,000 to the companies finalizing the Marine Drive stabilization project to repair the bin walls as part of the current project.
The contractor will schedule temporary roadwork repairs in January and return in March to repave the road for the final product.
Residents and visitors should be aware of the following on Marine Drive between Johnston Road and Cypress Street :
- Parking on Marine Drive and westbound traffic are unaffected
- Traffic detours for eastbound travel
- Construction noise and dust
- Construction deliveries
- Sidewalk closure and pedestrian detour to the Promenade

Frequently Asked Questions
Where and when is the construction occurring?
Construction will be occurring on the sidewalk and eastbound lane of Marine Drive roughly between Johnston Road and Grand Chief Bernard Charles Plaza. It will be starting on October 1, 2020 and will last approximately 4 months.
What is the reason for the construction?
You may have noticed that the asphalt on the eastbound lane of Marine Drive has been cracking over the recent years and conditions are getting worse. Construction works are required to reduce the potential for future road distress due to slope instability and to repair the existing asphalt on Marine Drive.
How are you proposing to stop future asphalt cracks?
The Construction works involve installing grouted micropiles vertically into the ground along two segments of Marine Drive. One segment will also receive inclined soil anchors. By installing the works from under the sidewalk, we will be minimizing blockage/interference of the roadway.
How do you install steel pipes into the ground?
The steel pipes will be installed using a temporary steel casing that is drilled into the ground. The temporary steel casing will be drilled to the required depth (between 9 m and 15 m), the steel pipe lowered inside the casing using a winch, and then the temporary casing removed while cementitious grout is pumped in the hole to infill the casing and pile. There is no pile driving required using this drilling method and vibrations are expected to be minimal (much less than pile driving).
How noisy will the construction be?
Residents should expect noise levels that are typical to construction sites of this magnitude. Similar drilling equipment was used during the pipe pile installation at Memorial Park and during the construction of the West Beach Parkade. All works will be in accordance with hours specified in the City of White Rock’s Noise Bylaw (7:30 a.m. to 7 p.m. Mon. – Fri. 9 a.m. to 7 p.m. Sat.). Work is not permitted on Sunday’s or Statutory Holidays.
How will the construction affect vehicle traffic on Marine Drive?
The eastbound lane of Marine Drive will be closed for the duration of the project. Eastbound vehicles will be detoured at Vidal St. to Victoria Ave./Columbia Ave. Minimal disruptions are expected for Westbound traffic.
How will the construction affect pedestrian traffic on Marine Drive?
The sidewalk on Marine Drive within the project extents will be closed to pedestrians for the duration of the project. Pedestrians will be detoured to the promenade south of the site or to Columbia Avenue.
Will my parking be affected?
Resident only parking along the north shoulder of Marine Drive will remain as-is and will be permitted.
Will there be any dust from the construction?
The Contractor is required to contain all dust and potential debris within the construction site. Diverters will be used on the drilling equipment to deflect drill cuttings and dust into a containment bin. Erosion and sediment control measures will be in place to contain mud and dirt within the construction area.
What will the construction area look like?
Temporary steel fencing and hoarding will be in place around the construction area. Tarps or mesh will be attached to the fencing to reduce distractions for the traffic on Marine Drive. Large excavators and drills will still be visible above the temporary fencing; however, most of the works will be hidden behind the hoarding. Residents should expect construction traffic coming in and out of the site through the access gates during work hours.
