Gallant Avenue storm sewer replacement
To help reduce the risks of flooding, we replaced the storm sewer along Gallant Avenue in Deep Cove.
The existing storm sewer — which was subject to flooding in 2014 and 2018 — was replaced due to the increasingly heavy storms caused by our changing climate. The new sewer will be able to handle a one-in-200-year flood, help mitigate debris flows (branches, mud, and rocks that can block sewers), and provide improved habitat for fish in the inlet.
News and updates
May 2022 – Storm sewer project complete
The Gallant Avenue storm sewer replacement project is now finished, and the construction detour has been closed. In April 2022, Council approved the revegetation of Naughton Avenue and the installation of an unpaved walking pathway between Deep Cove Road and Deep Cove Crescent.
Thank you for your patience as we completed this important infrastructure project.
April 27, 2022 – Final paving on Gallant Avenue and Naughton detour closure
Final paving on Gallant Avenue is scheduled for Thursday, April 28, weather permitting. On paving day, a full road closure of upper Gallant will be required. Please follow all detour signage and traffic control instructions.
Following road markings and line painting on Friday, April 29, the Naughton Avenue construction detour will be closed to vehicles.
April 19, 2022 – Preparation for final paving on Gallant Avenue
Final paving on Gallant Avenue is scheduled for late April, weather permitting. The Naughton Avenue construction detour will be temporarily reopened on April 19 for approximately two weeks to allow crews to prepare for this work.
A full closure of upper Gallant Ave with a traffic detour will be required for two days to complete the final paving.
February 4, 2022 – Two-way traffic set to return on Gallant Avenue
The Naughton Avenue detour is scheduled to close towards the end of next week, following the substantial completion of the sidewalks on Gallant Avenue. Full-time, two-way traffic is expected along Gallant until the Naughton detour is temporarily reopened in the spring for the final sidewalk work and paving on Gallant Avenue.
Please note that parking along Gallant may be restricted to allow the contractors to do landscaping and other work.
We look forward to completing the landscaping work in Panorama Park in early spring and welcoming the public to enjoy the park once it is complete.
January 21, 2022 – Construction update
Sidewalk construction on Gallant Avenue is nearing completion. Once the sidewalks are constructed, two-way traffic will return on Gallant Avenue, and the Naughton Avenue detour will be closed. The detour will be briefly reopened later in the spring to allow for the final paving of Gallant.
Our contractor is also preparing to start landscaping in Panorama Park, with plans for completion by mid-spring. We appreciate the patience from the community and all park users as we work to reopen the entire area as soon as possible.
January 7, 2022 – Construction work set to resume
Weather-dependent construction work is scheduled to start the week of January 10. Much of the remaining work is landscaping, which will require slightly warmer temperatures.
Before the holiday break, sidewalks were poured on the south side of Gallant Avenue. The remaining section of the sidewalks and plaza will be constructed once weather conditions are suitable. The detour will close once single-lane alternating traffic is no longer required for the project. Final paving will take place in the spring.
With the recent snowfall and rain, please use caution as the ground may be slippery and uneven in some spots, especially areas that have not yet been paved. As always, please walk within the designated areas and follow the instruction of traffic control workers.
December 17, 2021 – Gallant Avenue holiday work schedule update
Construction crews will be pausing work for the holidays from December 24 to January 3. Access to businesses will remain open at all times, with temporary walkways in place where necessary.
The Naughton Avenue detour will remain open over the holidays, as some work remains on Gallant Avenue to be completed in 2022.
With snow in the forecast, our crews are prepped and ready to respond. Please exercise caution as winter conditions can cause slippery roads and sidewalks, especially as temperatures dip below freezing.
We wish you all a happy holiday and look forward to completing this important community flood protection project with minimal disruptions in 2022.
December 10, 2021 – Gallant Ave base-layer paving complete; detour remains in place
The base layer of asphalt and curbs have been laid down on upper Gallant Avenue, and temporary road markings are in place. The Naughton Avenue detour will remain open to one-way traffic while work requiring lane closures on Gallant Avenue is completed.
Traffic exiting Deep Cove will be routed along Gallant Ave. Please follow directions from traffic flaggers, and obey all traffic signs in the area.
Due to the unprecedented flooding, subsequent highway closures and supply chain disruptions in the Fraser Valley, our contractor will continue working on the sidewalks and other construction activities into the new year. Access to businesses will remain open at all times.
Please note the Naughton Avenue detour survey closes December 12. We encourage you to share your feedback on what you think should happen in the area.
December 3, 2021 – Gallant Avenue reopen
[3:45pm] Gallant Avenue has reopened to outbound traffic following bottom lift paving and line-painting. This is an important milestone for the Gallant Avenue storm sewer replacement project and we thank you for your patience.
December 2, 2021 – Closure of upper Gallant and traffic detour in Deep Cove
This Friday, December 3, due to anticipated favourable weather conditions, we are proceeding with paving work on upper Gallant Avenue. This will require a one-day full road closure of upper Gallant Avenue, between 7am and 8pm.
As a result of this paving work and road closure, vehicle traffic will be routed out of Deep Cove Village via the following detour: Naughton Avenue, Rockcliff Road, Raeburn Street, Banbury Road, Cliffmont Road to Deep Cove Road. Please see map below. Traffic flaggers will be posted at key intersections along the detour route to control traffic, assist buses and vehicles, and maintain safety for pedestrians and cyclists exiting the neighbourhood.
Access to Caledonia Avenue north of Gallant Avenue will be maintained via single-lane alternating traffic on Deep Cove Road.
Expect traffic delays throughout Deep Cove on Friday between 7am and 8pm. Please follow directions from traffic flaggers and leave yourself extra time to get to your destination.
We acknowledge the late notice for this closure and detour. Dry weather conditions are critical to paving work, and so we need to take advantage of the few remaining good weather days when forecasted in order to complete this important work.
Thank you for your understanding and patience as we work to complete the construction works on upper Gallant Avenue.
November 30, 2021 – Naughton detour reopening temporarily
The detour on Naughton Avenue will be temporarily reopened to ensure safe and efficient access in and out of Deep Cove during the heavy rain forecast this week.
Since the detour closed, more single-lane alternating traffic has been required than was initially anticipated, and significant rainfall from heavy storms in quick succession has created potholes on the gravel surface on upper Gallant.
Contractors will begin reopening the detour on Tuesday, November 30.
November 26, 2021 – Naughton Avenue detour closed
As significant construction nears completion, the Naughton Avenue detour was closed earlier this week. Traffic has been routed back onto Deep Cove Road and Gallant Avenue, and most remaining work on upper Gallant can be completed with a return to two-way traffic. Single-lane alternating traffic will be necessary intermittently over the next few weeks but is expected to become progressively less frequent towards construction completion. This is a standard practice for road construction that we apply across the District.
The temporary detour was constructed to avoid long wait times in the summer months due to heavy traffic. Now that traffic has returned to lower, off-season volumes, anticipated delays are expected to be minimal so in keeping with our previous commitment to the community, we closed the temporary construction detour. A couple of unforeseen challenges occurred mid-week due to weather impacts, resulting in more single-lane alternating traffic than we anticipated. We have been working to address these challenges and starting next week, anticipate less single lane alternating traffic which should bring traffic delays closer to wait times associated with other construction projects in our community.
This weekend, heavy rainfall is expected to continue and crews will be out managing creek and surface flows. Generators and pumps potentially needed for this mitigation work may be audible in the worksite area.
Please use extra caution when walking and driving in the area.
November 18, 2021 – Upcoming closure of Naughton Avenue detour
With the installation of the culvert now complete, the Naughton Avenue detour is expected to close during the week of November 22.
After the detour is closed, two-way traffic will resume on upper Gallant Avenue during non-construction hours. During construction hours, single-lane alternating traffic will be required to accommodate completion of road construction on upper Gallant.
Crews expect to pour new curbs on Gallant Avenue early in the week. Sidewalk construction, paving, and landscaping will follow over the next several weeks.
Naughton Avenue feedback survey
Starting Monday, November 22, we are seeking community feedback on possible directions for the future of the Naughton Avenue area. This engagement is to provide information to Council for direction on next steps. Learn more.
October 29 – Gallant construction work update

Detours during construction
Replacing the storm sewer requires significant excavation of upper Gallant Avenue, which will disrupt traffic and parking in the area.
To ensure the safe and efficient flow of cars, bikes, and pedestrians in and out of Deep Cove, we will create a detour by temporarily opening and extending approximately 100 metres of the Naughton Avenue right-of-way between Panorama Drive and Deep Cove Road.
This will allow us to create a short, counter-clockwise one-way loop, as shown here.

Background
Creating the detour route
A temporary detour using Naughton Avenue is the safest and most effective way to minimize disruption to Deep Cove residents and businesses throughout construction. By temporarily opening Naughton Avenue, we can:
- avoid single lane alternating traffic through the work zone, which would result in heavy delays exiting Deep Cove during the busy summer season
- avoid a circuitous detour through the surrounding neighbourhood and elementary school
- improve the safety and performance of the Panorama/Gallant intersection by streamlining traffic
- ensure emergency response vehicles have direct access into and out of Deep Cove
Other routes we considered
Other construction detour options were evaluated to preserve the safe and efficient flow of pedestrians, transit, and traffic into, out of, and within Deep Cove during the storm sewer project including:
- Single lane alternating traffic on upper Gallant
- Clockwise or counter-clockwise one-way loop along Cliffmont, past Cliffmont Elementary and along Rockcliff
- One-way loop into and out of Deep Cove on a new Naughton Avenue extension, connecting Deep Cove Road to Naughton Avenue (the chosen option)
We assessed each option for pedestrian and cyclist safety, traffic flow and delay, and traffic and transit operation. Vehicle, cyclist, and pedestrian counts were taken at several locations throughout Deep Cove and used to simulate mobility and delay. We also evaluated impacts to transit service and assessed each route for operational issues such as road widths and turning radius.
The single lane alternating option on Gallant was eliminated because it would cause gridlock exiting Deep Cove for residents, transit, and visitors.
The Cliffmont/Rockcliff route was eliminated because of pedestrian safety close to the elementary school, excessive delays along the entire route, road width and turning radii challenges for vehicles, and extensive impacts to transit service and routing.
The Naughton Avenue extension has minimal impact to traffic flow, is the safest option for pedestrians, has very minimal impact on transit service, and has sufficient width to accommodate traffic safely.
Other projects
Other projects in Deep Cove
The provincial and federal governments are offering grant funding to communities who want to improve their outdoor spaces, in light of the COVID-19 pandemic. We are exploring opportunities to create a more livable Deep Cove by applying for this funding, which would cover 100% of the costs involved.
For more information on this project, please visit the Livable Deep Cove page.
This proposal is not directly related to the Gallant Ave storm sewer replacement project. The temporary construction detour being put in place to accommodate the sewer replacement does not need to remain in place at the end of the project in order for this project to work.
As this video overview explains, this project is subject to approval of the grant funding and public engagement with the community.
