Webinar – Low Impact Development (LID) Performance in New Build Residential (Previously Recorded)

Online anytime!
Estimated time requirement: 1 hour
Instructor: Jordan Wiedrick

Course Description

Stormwater management performance of Low Impact Development (LID) has been well documented at an individual LID feature level. However in Ontario little is known on how LIDs perform in managing stormwater at the subdivision scale. CVC has been collecting performance data from two newly constructed residential subdivisions within the Credit River Watershed. These two sites utilize a variety of LID stormwater treatment and storage features throughout the subdivision to manage stormwater.

Wychwood Neighbourhood is located in the City of Brampton and utilizes a combination of LIDs to manage and treat all stormwater runoff prior to conveying residual runoff to the Municipal storm system. Typically, a subdivision this size would require a stormwater pond. Wychwood was designed to meet runoff volume control design requirements solely through LIDs.

In Meadows in the Glen, located in Halton Hills, LIDs are used to treat and store stormwater runoff upstream of traditional stormwater ponds. The impact the LID features have on pond performance and maintenance are being observed by monitoring the inlets and outlet of the pond.

All season water quality and quantity monitoring data from Wychwood and Meadows in the Glen are presented to demonstrate the performance capabilities of LIDs as the primary management feature or as treatment train, integrated within the stormwater infrastructure upstream of a traditional pond. Additionally, site specific assumption protocols developed for Meadow in the Glen are presented to provide municipalities with tools to ensure LID features are performing to design standards prior to subdivision assumption.


Who Should Attend?

This webinar is intended for stormwater engineers, planners, conservationists and municipal staff operators.


Learning Objectives:

1. Overview of LID performance in terms of site hydrology and stormwater quality including the ability of LID features to provide significant peak flow and volume reductions for a range of runoff event sizes
2. How the use of assumption protocols within subdivision development planning can assure municipalities are assuming stormwater feature performing to design standards
3. LID stormwater storage performance upstream of pond can impact pond conditions if ponds are design with typical subdivision pond storage criteria
4. How performance monitoring and maintenance inspections can help identify ways to improve on LID design and plan for efficient asset management.
