Environmental Projects and Studies

In partnership with the town, Conservation Halton is undertaking a study to update flood hazard modelling and mapping within Kent Gardens, the QEW Corridor, Midtown Oakville Growth Area and adjacent areas. 

Conservation Halton regularly reviews and updates flood hazard modelling and mapping to fulfill the requirements of Ontario Regulation 686/21 and Ontario Regulation 41/24 under the Conservation Authorities Act.  

Flood hazard mapping is an important tool that supports Conservation Halton’s regulatory, planning and flood forecasting and warning programs. This information also supports municipal emergency management planning, flood mitigation, and infrastructure design.

To learn more about this study or share flood observations, visit Conservation Halton's Public Notices and Engagement page.

In 2008, the town completed a Flood Prioritization Study. The study looked at major open-channel waterways, streams, rivers and lakes to identify flood-sensitive areas in Oakville. 

One of the objectives of this study was to see all flood-sensitive areas in relation to one another and categorize areas as low, medium or high risk of flooding.

Now that the study is complete, the town is in a position to take advantage of provincial, federal or private flood reduction/mitigation funding programs should they come available.

The Fourteen Mile and McCraney Creek Flood Mitigation Opportunities Study assesses riverine flood risks for Fourteen Mile and McCraney Creek and recommended solutions to reduce flooding risks.

The Joshua’s Creek Flood Mitigation Opportunities Study assessed riverine flood risks along Joshua’s Creek south of Upper Middle Road to Lake Ontario and possible mitigation measures to help reduce flooding.

The Lower Morrison and Lower Wedgewood Creek Flood Mitigation Opportunities Study assessed riverine flood risks for Lower Morrison Creek and Lower Wedgewood Creek and recommended solutions to reduce flooding risks.

We have completed the Munn's Creek Flood Mitigation Opportunities Study. 

The study area included lands south of Upper Middle Road to the Morrison Wedgewood Diversion Channel. The purpose of the study was to assess impacts from riverine flooding, assess potential risks, and develop mitigation options.

The recommended solution to reduce flood risk includes the replacement of existing culvert crossings with larger structures, once the culverts have reached their end of service life.   The structures recommended for upgrades include:

• McCraney Street West culvert
• Miller Road culvert
• Oakdale Drive to Onslow Court pedestrian culvert crossing.

The recommended culvert upgrades will also be designed to improve fish habitat and wildlife passage and enhance the ecological function of the Munn's Creek corridor.

The goal of the Saville Area Stormwater System Improvement Study is to identify drainage deficiencies, explore opportunities for stormwater system improvement, and develop preferred options to improve drainage.

We have completed the Sheldon Creek Flood Mitigation Opportunities Study to identify flood-prone sites to determine the most practical and responsible options to reduce flood risk.

Several alternatives were evaluated based on environmental, physical, social, and economic considerations. The options selected are a combination of berm construction and emergency preparedness.

The study was carried out in accordance with the requirements as described in the Municipal Engineers Association’s Municipal Class Environmental Assessment (EA) document, approved under the Ontario Environmental Assessment Act.

The town is carrying out a Municipal Class Environmental Assessment to identify erosion risks, define erosion hazards, and develop preferred options to mitigate erosion for East Morrison Creek.

The town is investigated opportunities to rehabilitate a section of Sixteen Mile creek valley slope located just upstream of the Rebecca Street west bridge abutment.

Construction is tentatively planned for 2027 (subject to budget allocation, permit timing, harbour operations, and weather conditions).

The Town of Oakville is working to address erosion issues along Sheldon Creek through targeted rehabilitation and stabilization of two creek bank sections. Approximately 55 metres of erosion control work is planned.
