The location for the artificial turf facility has changed.
Construction of an artificial turf facility in the Terwillegar Heights District Park is not recommended due to unstable soil conditions.
This project was funded to the end of preliminary design. During this phase of work, a geotechnical assessment of the site was completed which identified poor conditions for construction of this type of field. Requirements for stabilizing the site, in an effort to mitigate substantial ground movement, are not financially viable. An alternate location is a better solution.
This is a unique and uncommon scenario. The City completes geotechnical assessments of the project site during design, in preparation for potential construction. These assessments give recommendations for foundations for the proposed facilities. The extremely poor soil conditions discovered were not expected.
City artificial turf facilities serve a large geographic area of the city. Along with other potential locations, the Terwillegar Heights District Park site was identified in the 2009-2015 Artificial Turf Plan as a priority location for the southwest area of the city. Other district parks, existing or planned, will be investigated for potential to accommodate an artificial turf facility to serve the southwest population. It is unlikely that these alternate locations will have geotechnical conditions as difficult to build on as the Terwillegar site, so construction is anticipated to be less risky and expensive. Depending on the new location, it may be possible to repurpose the design created for Terwillegar Heights Artificial Turf, leveraging the work and public engagement completed to date.
The area of Terwillegar Heights District Park that was identified for the artificial turf facility may be used for other purposes if the soil conditions and subsequent costs are considered. It is the requirements for an artificial turf field in combination with the shifting nature of the soils that resulted in an obstacle for this specific project.
- The Artificial Turf Strategy will be updated in the next budget cycle (2019-2022) as part of a larger Sportsfield Strategy. At this time, the proposed locations and priorities for artificial turf sites throughout the city will be updated and a new priority location for the Southwest determined.
- The Terwillegar Heights District Park Concept Plan will be revisited to address areas of the park where changes in use are being considered. The public will have opportunities for engagement when this project begins in Q1 2019. Open Space Planning and Design will be leading this process.
