​Rain Gardens: Improve Stormwater Management in Your Yard

Stormwater runoff can move quickly towards storm sewers, collecting harmful substances on its way.

SLOW THE FLOW and help filter pollution from stormwater. Rain gardens collect runoff after a rain or snowmelt allowing it to soak into the ground to recharge local groundwater.

Stormwater refers to rain and melted snow and ice. The runoff from your roof, driveway and other hard surfaces in your yard is typically directed towards the street and into the municipal storm sewer system. On its way, it has picked up harmful substances such as road salt, heavy metals and oils. This polluted water ends up in our creeks, rivers and streams, and ultimately Lake Simcoe where it can harm water quality and aquatic habitat.

There are several ways that you can reduce runoff and better use stormwater in your yard while ensuring proper drainage. One relatively easy and attractive method is a rain garden. A rain garden is a planted or stone-covered bed specifically designed to receive stormwater and allow it to be slowly absorbed into the soil (infiltration).

The Benefits of Rain Gardens

Rain gardens also provide good habitat for butterflies, birds and other wildlife. Unlike the surrounding grass lawn, which requires much more upkeep, rain gardens contain native plants that need little maintenance once they are established.

  1. They work to keep our water clean
    Pervious soils act as a natural filter. By diverting runoff from the storm sewers and into the ground, we are encouraging this natural filtration.

  2. They require very little maintenance
    The plants are native to the area and hardy to our conditions. Once established, no watering is needed and these perennials will grow back every year.

  3. They add beauty to the landscape
    Rain gardens look nice and can complement many design styles. They can increase your property's curbside appeal and market value

Fact Sheets

De La Salle Park Community Rain Garden Project - Georgina (York Region)


Rain gardens like this, installed on properties across the watershed, create a positive impact on the waters that flow into Lake Simcoe.

Through LSRCA's Landowners Environmental Assistance Program – or LEAP, we are now accepting funding applications from urban landowners to offset the cost of building a rain garden on your own property.

De La Salle Park is located in Georgina, York Region. This rain garden was designed, constructed and funded with the help of the Ontario Water Centre for Innovation, Park Lane Nurseries, the Town of Georgina, the Regional Municipality of York and Lake Simcoe Region Conservation Authority.
