Gallant Avenue storm sewer replacement

Map showing the location of the storm sewer being replaced

To help reduce the risks of flooding, we are replacing the storm sewer along Gallant Avenue in Deep Cove.

The existing storm sewer — which was subject to flooding in 2014 and 2018 — must be replaced due to the increasingly heavy storms caused by our changing climate. When complete, 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 an improved habitat for fish in the inlet.

We expect the project to be completed by fall 2021.

Community Survey: With scheduled construction coming to an end, we have launched a feedback survey to hear from the community about the future of the Naughton Avenue area. Learn more.

News and updates

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

Construction work will be ongoing along Gallant Avenue and in the creek. Crews continue to replace sidewalks on Gallant Avenue and prepare for planting new trees. Where possible, the contractor will perform weekend work from 7am-7pm Saturdays and Sundays. On October 31, any heavy work will stop at 5pm. 

Please exercise caution around the construction site, especially on Halloween. Follow the directions of the traffic control flaggers and project personnel. Temporary walkways will remain installed, and access to businesses will remain open at all times. 

October 22, 2021 – Construction work on Gallant

Construction work will be ongoing this weekend on Gallant Avenue between Panorama Drive and Caledonia Avenue, as well as in Panorama Park. Weekend working hours are between 7am-7pm. Temporary walkways will remain installed, and access to businesses will remain open at all times. Please follow the directions of traffic control flaggers and project personnel.

Last week, the contractor hit a major milestone in completing the concrete culvert pipe, and the culvert was operational for last weekend’s heavy rains. Inlet and outlet channel work is continuing as weather permits.

Heavy rain is forecast to begin on Friday, October 15 and continue through the weekend. Crews will be on-site to monitor and control water flows in Gallant Creek.

During the week of October 18, crews will begin removing sidewalks along both sides of Gallant Avenue between Panorama Drive and Caledonia Avenue. Temporary walkways will be installed, and access to businesses along Gallant Avenue will remain open at all times. Please follow the directions of traffic control flaggers and project crews.

Weather permitting, creek channel work along Gallant Avenue and Panorama Park will be ongoing, and weekend work may be necessary starting October 23.

September 27, 2021

On Thursday, September 20, contractor crews will be observing the National Day for Truth and Reconciliation. Only workers needed to maintain the creek bypass are expected on site.

Please note, due to continued heavy rainfalls expected this week, crews may need to work outside of regular working hours to ensure safe passage of creek flows.

September 16, 2021 – Preparation for heavy rains

Heavy rains are forecast to begin on Friday, September 17, and continue overnight into Saturday, September 18. We are taking additional measures and contingency plans are in place to control water flows in Gallant Creek, including adding extra water pumps.

Crews will be working in the area over the weekend. Residents and businesses may notice noise from water pumps and additional lighting. Please use added caution when travelling on Gallant Ave., Panorama Dr., and Deep Cove Rd. and obey flaggers as traffic patterns may change at short notice.

September 14, 2021 – Update on the storm sewer replacement project

Project manager Wendelin Jordan provides the latest update on the Gallant Avenue storm sewer replacement project.

 

September 3, 2021 – Culvert construction continues up Gallant Ave., businesses remain open

During the week of September 6-10, storm culvert installation will progress from the intersection of Gallant Ave. and Panorama Dr. and head up Gallant Ave.

To accommodate this work, construction fencing on upper Gallant is expected to be moved mid-week to the sidewalk next to the businesses on the north side of Gallant, and pedestrian patios on this section of the street will be removed.

All businesses will remain open and be accessible to pedestrians. During construction work on upper Gallant, the street will remain open to one-way traffic and two-way pedestrian traffic; however, some sidewalk closures will be necessary.

August 27, 2021

During the week of August 30, construction will be moving into the intersection at Gallant Avenue and Panorama Drive. Two additional street trees on upper Gallant must be removed in order to facilitate the construction of the storm culvert.

In addition, the street lights on Gallant Avenue will be decommissioned and replaced with temporary street lighting for the duration of the project. The permanent street lights will be reinstated at the end of the project. 

August 20, 2021 – Culvert construction work

During the week of August 23-27, new culvert and creek outlet construction continues in Panorama Park. Pipe installation crews will be working towards the intersection of Gallant Ave and Panorama Drive and later heading west up Gallant Ave. Expect minor traffic delays.

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:

  1. Single lane alternating traffic on upper Gallant
  2. Clockwise or counter-clockwise one-way loop along Cliffmont, past Cliffmont Elementary and along Rockcliff
  3. 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.
