Lyndale Drive Riverbank Stabilization

Lyndale Drive is a scenic route that is popular with pedestrians and cyclists. It is also designated as a portion of the City's primary line of defense and serves an important role in the City's flood protection strategy. This project will address riverbank instabilities along Lyndale Drive between Lawndale Avenue and Claremont Avenue, where this risk has not yet been fully addressed. The project will also accommodate the completion of the walk-bike path between Ferndale and Lawndale.

Background

Lyndale Drive is a local street that forms a portion of the City's PLD to defend against flooding along the Red River. As this street provides scenic vistas of the Red River and is adjacent to Lyndale Drive Park, it is popular amongst residents, pedestrians, cyclists and other recreational users. The section of Lyndale Drive between Lawndale Avenue and Gauvin Street has a history of riverbank instabilities, including major slope failures and erosion in the specific project area. These instabilities pose an unacceptable risk to the road, dike, sewers, and other infrastructure at the top of the riverbank, and have prevented the completion of the walk-bike path.

The Lyndale Drive project site has been identified in the City of Winnipeg's Capital Budget as one of the City's top priorities for riverbank improvements. This prioritization is based on evaluations done as part of the City of Winnipeg's Riverbank Asset Management System.

Stabilization of this riverbank will ensure the long-term integrity of the street, PLD and other infrastructure by future slope failures from impacting these assets and allowing for the walk-bike path to be constructed adjacent to the road.

To address the erosion and instabilities along the upstream portions of Lyndale Drive, riverbank improvement projects were undertaken in 2000, 2013 and 2017, however, the length of riverbank along Lyndale Drive between Claremont Avenue and Birchdale Avenue has only been improved with limited erosion protection work. There remains a risk that slope instabilities could impact the road. Monitoring has identified ongoing slope movements have confirmed the risk to the path and street.

Without undertaking the slope improvements to prevent further damage, there is not presently a way of connecting the path network across the gap that presently exists between Ferndale Ave and Birchdale Ave.

This project will consist of a geotechnical investigation and an analysis of the riverbank to determine soil and groundwater conditions so we can better understand the risk to the area. The stability analysis will also be used to evaluate and design the appropriate stabilization measures.

While the design phase is not complete, it is expected that the stabilization will involve rockfill columns, slope re-grading, and potentially lightweight fill. The riverbank stabilization and re-grading works will be constructed starting in early 2021.

The project will also include a preliminary design for the path connection, which will be implemented once funding has been secured

Frequently Asked Questions

Open all | Close all

Why haven't I heard about this project before? How was it selected?

The City owns over 100 km of riverbank spread over 200 properties or unique segments on the Red and Assiniboine Rivers alone. The Waterways office maintains a Riverbank Asset Management System which is used to characterize riverbanks, and help identify those that are high priority, based on the risk to public land and infrastructure. This site on Lyndale Drive had been identified as a top priority, and has been listed as such in the City's Capital budget over the past several years. However this project had not been funded. In the summer of 2020, the Lyndale Drive project received funding under the Province of Manitoba's Disaster Prevention and Climate Change Resiliency program.

Date added: September 2020

What is the project budget?

This project is being funded through the Province of Manitoba's Disaster Prevention and Climate Change Resiliency program, which has allocated $4.6M for the engineering design and construction of these works. The City of Winnipeg is also contributing to the project by covering costs not eligible under the program.

Date added: September 2020

What time of year will construction occur and how long will it take?

Riverbank works are tentatively scheduled to begin in January 2021 and will take approximately 10 weeks. Street, path, landscaping and other utility work in the right-of-way will occur between spring and fall, 2021.

Date added: September 2020

Will there be a lot of noise during construction?

There may be some construction-related noise and traffic during the stabilization work. The project team will be taking noise into consideration when planning the construction activities and schedule.

Date added: September 2020

Will construction affect local traffic?

A traffic management plan will be developed to minimize traffic impacts in the area during construction. A noticed will be delivered to residents prior to the start of construction outlining any changes in access to local streets and paths.

Date added: September 2020

Will construction affect trees along the Red River?

It is anticipated that some trees along the riverbank and right of way may need to be removed. Tree removal will be considered during design and will be minimized as much as possible. If any trees need to be removed, they will be replaced with new trees during the site restoration phase. Trees and shrubs provide numerous benefits, especially along a riverbank where they also help to reduce erosion and improve stability.

Date added: September 2020

I thought the riverbank along Lyndale Drive had been stabilized already? Why wasn't this done earlier?

Various projects over the past 45 years have addressed segments of the riverbank along Lyndale Drive. Due to funding limitations or practical constraints, works have proceeded in phases. This project will complete the stabilization activities between Birchdale Avenue and Gauvin Street. Erosion protection works are required in Lyndale Drive Park (downstream of the current project area), though project funding has not yet been confirmed.
