What is a watershed plan?
A management document that lays the framework for protecting
and enhancing the natural environment, while guiding
development within the watershed
Recommendations are based on scientific studies and community
input
Durham Region and Clarington Official Plans include policies that
recognize the importance of watershed planning
As part of the OP Review Clarington has undertaken this study
• Will form the basis for the Courtice Employment Lands Secondary Plan

Characterize the Watershed
Establish Existing Conditions
• Groundwater Quantity/Quality
• Surface Water Quantity/Quality
• Aquatic Species and Habitat
• Terrestrial Natural Heritage
• Land-use (Current and Future)
Identify
• How the Watershed Functions
• Opportunities for Improvement
Set Targets and Evaluate
Management Alternatives
Develop a Watershed
Management Plan
Set Natural Environment Targets
Natural Heritage System
Based on Existing Conditions
• Based on existing natural environment
features
• Enhancement scenarios based on
CLOCA model
Water Budget
• Based on methods used for Source
Water Protection Studies
and the Preferred Management
Alternative
Specific Recommendations to
Guide Development and
Preserve the Natural
Environment
Imperviousness
• Based on current and future land-use
Management Alternatives
• Environmental Constraints
4
Existing Conditions
Land-use dominated by urban residential
and agriculture, with limited remaining
natural environment features
Headwaters located north of Bloor Street
Creek primarily supported by surface water
runoff
Natural environment features concentrated
along riparian corridors and in wetland area
north of Bloor St.
5
Existing Conditions
Land-use dominated by urban residential
and agriculture, with limited remaining
natural environment features
Headwaters located north of Hwy 2 in Maple
Grove Wetland PSW
Creek south of Hwy 2 primarily supported by
surface water runoff
Natural environment features concentrated
along riparian corridors and in Maple Grove
Wetland
6
Natural Heritage System
Based on existing natural environment features and
targeted enhancements
Includes Environmental Protection for a Natural
Heritage System
Water Budget
Defined High Volume Recharge Areas (HVRA)
Maintain pre-development infiltration rates postdevelopment in HVRAs
Impervious Surfaces
Enhanced stormwater control measures
Minimize runoff using new and existing technologies
7
Management Recommendations are made based on Existing Conditions and
the Environmental Constraints.
Set Management Goals
Set Objectives to meet the Goals
Identify Management Actions to achieve the Goals and Objectives
Regulation and Policy
Education and Stewardship
Land Dedication and Acquisition
Monitoring

GOAL – To Maintain and Enhance the Health, Quality, and Functionality of the
Ecosystem
Objective – Protect and Enhance the Natural Heritage System
Regulation and Policy
Define and Protect a Natural Heritage System within the Official Plan
Minimize the Impact of Development on Natural Heritage System
• An Environmental Impact Study (EIS) will be required for
development approval.
Negotiate Net Gains
Education and Stewardship – Support programs that increase
natural cover, forest cover, and riparian vegetation
Land Dedication and Acquisition – Focus on NHS Lands
Monitoring – To determine if objective is having desired effect
Watershed Management Plan was
approved by CLOCA Board on
Tuesday January 17, 2012.
Watershed Management Plan is
provided to Municipality of Clarington
Council to be referred to Staff for
consideration during the OP Review
process.
The Watershed Management Plan will
be used as the basis for development
of Secondary Plans
