We'll be constructing 2 dry ponds, as well as performing sewer upgrades. This work is currently underway and is expected to be completed by the end of the 2020 construction season. Have a closer look at a more detailed project timeline.​

Project overview 

The Parkallen Flood Mitigation Project was initiated with the objective of reducing the risk of flooding during high-intensity, low-frequency rainfall events. The selected concept included two dry ponds: one in the school site, and one in Ellingson Park, as well as two sewer upgrade areas, located in separate parts of the neighbourhood.

The majority of the overall project has been successfully completed. The construction of the Community Garden and the permanent restoration of the alley south of 67 Avenue and west of 112 Street will be completed in 2021.

Dry pond timeline

The construction of the dry ponds has been completed.

Residents can expect to see on-going maintenance within the fenced areas, including installation of soccer goal posts in mid-summer.

EPCOR has removed the fence around the majority of the site. Residents are expected to only use the space for light recreational activities (ie. no cleats or bikes on the sod) to give it additional time to become more durable.

Snow fence has been installed around the planting beds and toboggan hill to ensure the beds and seeded areas are protected. Any damage to the landscaping may impact the City of Edmonton's approval and significantly delay the opening of the space. In fall 2021, the City of Edmonton will complete an inspection to ensure the landscaping has established prior to the dry ponds transferring to the City for ownership and maintenance.

The supervisory control and data acquisition system (SCADA) has been installed in the dry ponds. SCADA is a computer system for gathering and analyzing real time data, which includes warning devices in the pond's drainage grates that notify EPCOR when it is filling with water. EPCOR staff can be dispatched as necessary to ensure the site is safe.

Sewer upgrade timeline

Alley 67 Avenue and west of 112 Street

The connection to the existing deep storm line on 67 Avenue has been completed and the road was opened in October 2020. Concrete restoration will be completed in July 2021.

An unexpected issue arose during construction relating to conflicts with the ATCO gas main in the alley which has delayed the completion of the work. The alley was temporarily restored to p​rovide residents access over the winter.

It is anticipated that ATCO will schedule the gas line lowering in summer 2021. ATCO will communicate directly with impacted residents when work is expected to begin and with further information on the work methodology. Any questions or concerns regarding the ATCO gas line lowering can be directed to ATCO at 780-733-2577.

Once the gas line has been lowered, EPCOR will then complete the permanent restoration of the alley. Further details about the alley restoration and closures to traffic, will be communicated closer to the start of the work.

The City of Edmonton will be responsible for the maintenance of the alley once the project has been completed.

Along 62 Avenue and 112A Street

The sewer upgrade work along 62 Avenue and 112A Street was completed in early November 2020.

The City of Edmonton has advised that planting of the replacement trees will occur in June 2021.

Community garden

Construction for the replacement community garden is scheduled to begin on June 14, 2021 and is expected to be completed by the end of July 2021. Please note, these timelines are estimates and may change based on weather and construction conditions.

During construction, residents can expect temporary no parking adjacent to the work area along the north side of 65 Avenue. The garden work area will remain fenced off until summer 2022 to allow for the landscaping to establish.
