Flood Prioritization Study
In 2008, the town completed a Flood Prioritization Study on the town's major open-channel waterways, streams, rivers and lakes to identify flood-sensitive areas in Oakville. The study used information from previous subwatershed studies and consolidated all the information into one document. One of the objectives of this study was to see all flood-sensitive areas in relation to one another. These areas were categorized as low, medium or high risk, enabling the town to start setting priorities for flood mitigation projects. The study has put the town in a position to take advantage of provincial, federal or private flood reduction/mitigation funding programs.
Future studies will look at the town's underground sewer network and overland flow routes, recognizing that these routes, if compromised, can also present a flood risk.
In June 2008, the town hosted three open houses to talk about the Flood Prioritization Study as it pertains to flood-sensitive areas in wards one, two, three and five. View the documents from these open houses below:

Flood Mitigation Opportunities Study for Fourteen Mile Creek/McCraney Creek Systems
The Town of Oakville has initiated a Municipal Class Environmental Assessment for a detailed assessment of mitigation and flood reduction alternatives for Fourteen Mile Creek and McCraney Creek from Lake Ontario to Dundas Street. Several flood-prone locations within the study area have been identified as high priority sites as part of the 2008 Town-wide Flood Prioritization Study.
The approximate limits of the project area are illustrated on the key plan. This study will involve a more detailed evaluation of creek flood-prone sites in an effort to determine the most viable and effective flood mitigation alternatives. It will determine the degree of flooding, identify and assess alternatives for mitigation, and recommend preferred alternatives to be implemented.
The study is being conducted in accordance with the requirements as described in the Municipal Engineers Association’s Municipal Class Environmental Assessment (EA) document (October 2000, as amended in 2007), which is approved under the Ontario Environmental Assessment Act. The appropriate project schedule will not be confirmed until the preferred solution is selected. The Class EA process will include public and agency consultation, an evaluation of flood reduction alternatives, an assessment of the potential environmental effects of the proposed improvements, and identification of reasonable measures to mitigate any adverse impacts.
Public Information Centres (PICs) will be held during the course of the project. The PICs will provide stakeholders with an opportunity to meet the Project Team, review the study scope and discuss issues related to the project, including alternative solutions, environmental considerations and evaluation criteria. Details regarding the forthcoming PICs will be advertised as the study progresses.
