A New Direction to Manage Stormwater

As urban areas in the Lake Simcoe watershed continue to grow, we must continue to explore alternative strategies to stormwater management. The idea behind innovative stormwater management is to reduce the amount of rainwater entering our storm sewers by increasing the amount that infiltrates into the ground.

To better manage stormwater, sustainable Low Impact Development (LID) practices can be applied to new undeveloped lands as part of the subdivision process, and to existing developed lands through retrofitting.

Learn more about stormwater management
by viewing one of the following video or case studies:



The neighbourhoods around Newmarket’s Western Creek are aging with roads in need of repair, while extensive development is increasing risk of flooding downstream during intense storm events. Find out what LID practices were selected as part of this retrofit project.

LSRCA added LID features such as bioswales, curbcuts, and permeable pavement to its aging parking lot. These features will help extend the life of the parking and walking surfaces and increase the number of parking spots. Learn more about LSRCA's new parking lot features and project outcomes. 



Staff and the Parent Teacher Association at the St. Nicholas School were looking for a low cost solution to providing a shaded play area. Find out how LID practices were incorporated into the design of the new play area.


Fostering Sustainability through Innovation

sustainable-technologies-evaluation-program-logo.jpgThe Sustainable Technologies Evaluation Program (STEP) is a multi-agency initiative developed to support broader implementation of sustainable technologies and practices within a Canadian context. Lake Simcoe Region Conservation Authority is a proud partner of STEP and recently developed, alongside Credit Valley Conservation and Toronto and Regio​n Conservation Authorities, the Low Impact Development Treatment Train Tool, an exciting new open-source tool created to help developers, ​consultants, municipalities and landowners better understand, plan and implement sustainable stormwater practices.
