Rainwater Management Plan
A study of all stormwater-related infrastructure and natural assets.
The Rainwater Management Plan (RWM) is the overall vision that looks at all stormwater-related infrastructure and natural assets to deliver a long-term plan. This includes a financing plan that aligns with Council’s Strategic Plan to improve resiliency and protect our infrastructure.
Building on previously completed stormwater infrastructure assessments, environmental assessments and flood studies, the RWM will offer a complete approach to planning and implementing stormwater-related infrastructure in the future. It includes all town-owned tangible and natural assets related to storm pipes, culverts, shoreline, harbour shoreline, creeks, stormwater ponds and ditches.
The plan will prioritize recommendations from the studies to deliver a long-term plan that will obtain the maximum benefit and create the most resiliency possible in an effective and cost-efficient manner.
The Federation of Canadian Municipalities provides an overview of why municipalities need to consider climate risk and adopt asset management plans for the long term, . It also explains how municipalities need to prioritize and evaluate risk to get the best value for taxpayers’ dollars.
The various studies and infrastructure assessments that feed into the RWM Plan with recommendations to be prioritized across the network are listed below.

A study focused on areas of the town that were developed prior to 1980 to identify long-term improvements of the town’s stormwater management system.
Work to date includes assessment of the condition of the existing stormwater system and collection of background data, as well as performance assessment of the existing stormwater system to identify opportunities to decrease flood risk in more intense storm events.
The third phase is underway as part of the RWM Strategy to develop and assess funding strategies to implement the plan.
These studies evaluate the options to mitigate flooding from extreme rain or melting snow in streams, rivers and creeks when they exceed the capacity of their natural or constructed channels to better accommodate waterflow and prevent flooding.
Areas studied include: Fourteen Mile and McCraney Creek systems, Joshua’s Creek, Lower Morrison and Wedgwood Creek systems, Munn’s Creek and Sheldon Creek. Recommendations range from emergency preparedness and minor improvements to significant infrastructure upgrades.
The outcomes of these studies help determine the long-term hierarchy of needs of the RWM Strategy.
This flood impact study and assessment of the infrastructure in Oakville Harbour and Bronte Inner Harbour assessed the current condition of infrastructure and identified improvements to help reduce the potential for flooding at higher lake levels.
Requirements will also feed into the long-term hierarchy of needs of the RWM Strategy.
Through the town’s asset management planning, condition assessments are regularly completed on various stormwater-related assets to determine what life-cycle renewal and rehabilitation works are required.
Some of this infrastructure is approaching end of life and could potentially require significant investment in the future.
Maintaining our existing infrastructure in a good state is essential in ensuring the stormwater network functions properly.
