Retrofitting Stormwater Ponds

Purpose

To reduce the impact of stormwater runoff from urban areas by retrofitting existing stormwater management facilities. Addressing stormwater contributes to protect and/or improve the water quality and quantity of Lake Simcoe and its tributaries.

Objectives

Retrofit Stormwater Management Facilities to:

Reduce stormwater runoff to pre-development conditions as close to the source as possible
Prevent erosion and reduce phosphorus loads to Lake Simcoe and its tributaries
Contribute to the protection or enhancement of water quality and quantity within the Lake Simcoe watershed
Recognize stormwater retrofit projects as a means to achieving the overall phosphorus water quality target

Eligible Projects

Retrofitting of existing stormwater ponds to provide water quality and quantity control

Project Details

The following minimum criteria must be met for a project to be approved:

Projects on public lands should have a with a written commitment from the public landowner to enter into an Agreement to include the following: inspect and maintain the facility to the satisfaction of the Conservation Authority, and if applicable, the amended Environmental Compliance Approval (ECA) and to identify the project within an established asset management database and provide inspection and maintenance records to the Conservation Authority upon request

All projects will follow the most current Conservation Authority’s Technical Guidelines for Stormwater Management Submissions
For Recharge, potential funding is based on the net (post minus pre-retrofit) annual infiltration at $44.97/m3/year or more recent board approved rate
For Phosphorus reduction, potential funding is based on the net (post minus pre-retrofit) annual phosphorus reduction or more recent board approved rate
- Offset Value = $35,770/kg/year
- Offset Calculation = (P load in kg x $35,770)
One tool only must be selected and used either:

Ministry Environment, Conservation and Parks Phosphorous Budget Tool. For a copy of this Phosphorus Budget Tool, please e-mail restoration@lsrca.on.ca.
STEP-Water Low Impact Development Treatment Train Tool for phosphorus calculations. No mixing of the phosphorus tools, loading rates, or removal rates will be permitted
