The City's stormwater assets are critical to ensuring effective and sustainable stormwater management. This includes the maintenance, rehabilitation, and enhancement of infrastructure to protect the community from flooding, manage water quality, and support environmental stewardship.
Stormwater Infrastructure
Assets that support Barrie's stormwater system have a replacement value of approximately $1.55B. The largest portion of the asset portfolio is storm sewers, which account for approximately 55% of assets by replacement value.
| Asset Category | Asset Class |
|---|---|
| Collection & Conveyance | • Storm Sewers • Culverts • Catch Basins • Maintenance Holes • Ditches |
| Storage & Treatment | • Stormwater Management Facilities • Manufactured Treatment Devices |
| Low Impact Development | • Bioretention • Dry Swale • Enhanced Grass Swale • Vegetated Filter Strip • Perforated Pipe System • Sand Filtration Bed • Soakaways, Infiltration Trenches & Infiltration Chambers |
| Natural Features | • Natural Watercourses |
Asset Management Plan Key Findings
Full information about the City's management of stormwater assets is contained on pages 97–115 of the 2025 Corporate Asset Management Plan.
The 2025 Corporate Asset Management Plan includes three key findings:
- The City's stormwater management facilities require an additional $0.4 million annual investment for sediment removal to help mitigate risks of pollutant discharge into natural waterways.
- The City is upgrading culverts to increase flood resiliency. Critical areas are prioritized as funding is not available to upgrade all culverts.
- There is an investment gap associated with replacing aging culverts over the next 10 years. Deteriorated culverts present the risk of unplanned disruptions (sinkholes), which in turn force the need for costly reactive repairs.
