24 Street SE Stormwater Pond and Ogden Landfill Remediation

Project update - April 2024


Upcoming landscaping

Remaining work including aerating the soil, moving materials, applying a layer of soil, and planting more seeds is set to begin in late April or early May depending on weather conditions. Once work begins, it is anticipated to take approximately 15 days.

The new seed areas will be watered for six weeks following seeding. This type of watering is typically permitted even when there are water restrictions in place because it’s part of construction work. The hours of work will be 7 a.m. to 7 p.m. each day.

Landscaping maintenance

Once the work is completed, the site will re-open, but there will be intermittent closures for watering.

The sidewalk along the east side of 24th Street will remain open to pedestrians for the duration of construction.

Pathway closure signage will be in place to help ensure public safety. Provisions are put in place to keep noise, dust, and other disturbances at reasonable levels.

Over the life of the pond, anticipated ongoing maintenance activities may include emptying trash bins, weed control, and sediment removal from the underground oil grit separator system. Primarily native grasses have been seeded and will take time to fully establish. These grasses will not typically be mowed, except for weed control purposes.

Thank you to all residents for your patience and understanding as we continue to work to improve our stormwater system and build part of the future LRT corridor.

Project Background


In 2021, The City of Calgary completed construction of a new dry storm pond on the northwest end of the former Ogden  Landfill (along 24 St. SE).

We have also completed the construction of an embankment adjacent to the storm pond  which will be part of the corridor for the future Green Line LRT.

The majority of work took place from July to December 2020, with a pause in work from January to mid-April 2021.

What we did in Spring 2021: 

  • Our contractor, Morgan Construction & Environmental LTD., and their subcontractors, completed landscaping activities such as; adding topsoil and seed placement, planting shrubs and trees, and installing stone edging as well as, benches.
  • Commissioned the storm sewer system components;
  • Removed existing fence along 24th St and installed a new fence on the east side of the pond;
  • Paved access points to and around the pond.

The construction of this project is now considered to be complete and the site is open to the public as of July 1, 2021.
