Stormwater Stewardship Grants

Stormwater Stewardship Grants

Roofs, driveways, parking lots, roads, and patios are all impermeable surfaces, meaning they do not allow water to absorb into them. The goal of stormwater stewardship projects is to either change impermeable surfaces into permeable ones, or to direct water that lands on one of these impermeable surface types to an area where the water can be absorbed into the ground.

Stormwater stewardship projects help reduce both stormwater flowing into the municipal sewer system and stormwater flowing directly into local watercourses, Cootes Paradise, Hamilton Harbour and Lake Ontario. Stormwater often carries pollutants which can be harmful to fish and other aquatic life. These projects can help mitigate these issues by filtering stormwater, reducing the transport of pollutants, and helping reduce soil erosion.  Stormwater stewardship projects also offer benefits of enhancing your property’s landscape, improve curb appeal and possibly even elevate property value.

There is limited funding available and funds will be approved on a first come first served basis. We are offering grants to property owners in the Hamilton Conservation Authority’s watershed to cover 50% of costs up to a maximum of $2,500 for eligible projects.
