The District of Sparwood, B.C., wanted to understand how to improve water quality in the Elk River through better management of natural assets. Specifically, the Sparwood project identified a natural pond at the outlet of a culvert and explored options to manage, rehabilitate and monitor it to control erosion and reduce discharge of sediment and other effluents.
The project measured how much sediment the pond would capture under four different scenarios and analyzed the economic costs of the existing pond, an enhanced pond and an engineered alternative. The economic costs included upfront or capital costs, maintenance costs and life-cycle costs.
Results showed that an enhanced pond — now and with climate change — would capture the most sediment, around 94 per cent. Life-cycle costing ranged from no capital or maintenance costs for the existing pond to $248,000 for an engineered alternative over 25 years. The District of Sparwood can use this information in asset management decisions, both at this specific site and other sites where the approach is replicated.
Municipal Natural Assets Initiative — Cohort 2 National Project Summary Report: City of Courtenay, British Columbia
This project summary shows how natural infrastructure can help local governments and communities reduce flood risks. Communities like the City of Courtenay recognize it is as important to understand, measure, manage and account for natural assets as engineered ones.
Municipal Natural Assets Initiative — Cohort 2 National Project Summary Report: Florenceville-Bristol, New Brunswick
With increasingly frequent and intense rainstorms along the Saint John River causing major flooding and other issues, the Town of Florenceville-Bristol explored how natural assets such as forests could help manage stormwater, erosion and flooding at lower cost and increase resilience to climate change.
Municipal Natural Assets Initiative — Cohort 2 National Project Summary Report: Oshawa Creek, Ontario
The project measured how the natural assets in the city of Oshawa, Ontario, are currently reducing erosion and maintaining water quantity and quality, and identified opportunities to improve both through management and development practices.
Municipal Natural Assets Initiative — Cohort 2 National Project Summary Report: Riverview, New Brunswick
The Town of Riverview, N.B., valued stormwater management services of wetlands in hopes of avoiding building new infrastructure. The wetlands and surrounding areas provide valuable storage. If it is lost, increasingly costly stormwater designs will be needed.
Municipal Natural Assets Initiative — Cohort 2 National Project Summary Report: Village of Riverside, New Brunswick
The Village of Riverside-Albert partnered with the Southeast Regional Service Commission (SERSC) to increase understanding of natural assets in the community and to learn how to manage them for a sustainable drinking water supply.
