Why Manage Stormwater?

“The ultimate goal of stormwater management is

to maintain the health of streams, lakes and

aquatic life as well as provide opportunities for

human uses of water by mitigating the effects of

urban development. To achieve this goal

stormwater management strives to maintain the

natural hydrologic cycle, prevent an increased

risk of flooding, prevent undesirable stream

erosion, and protect water quality”

Municipal Interest

Stormwater is considered in three distinct areas of municipal interest;

1. through the Planning and Land Development

processes;

2. Environment Assessments

3. Capital programs delivering engineering projects

of the municipality e.g. roads, erosion, facility design, etc.;

Stormwater Infrastructure

• Stormwater management infrastructure is generally identified by the local area municipalities through the preparation of Master Environmental Servicing Plans, prepared in support of secondary plans, and constructed through the land development process.

• The Region of Peel identifies new Regional road storm water requirements through the preparation of Environmental Assessment process (EA’s) as each road project is being designed.

Additional Municipal Interests

• Climate Change

• Low Impact Development

• Source Water Protection

• Flooding

• Inflow and Infiltration to Sanitary Systems

• Operations and maintenance programs and practices.

Green Infrastructure

Green infrastructure:

means natural and human-made elements that provide ecological and hydrological functions and processes. Green infrastructure can include components such as

natural heritage features and systems, parklands, stormwater

management systems, street trees, urban forests, natural

channels, permeable surfaces, and green roofs.

National and Local Programs

The Canadian National Water & Wastewater Benchmarking Initiative was started in 1998 and has since grown to 55 member municipalities participating in stormwater, water and wastewater benchmarking. Benchmarking is the ongoing process of comparing products, services and practices with those of similar organizations. The ultimate goal is always to improve quality and performance. Southern Ontario Municipal Stormwater Discussion Group was started in 2006 and has since grown to 60 member municipalities participating in stormwater discussions. Ontario Municipalities only, meeting quarterly to discuss common issues

• SWM Infrastructure Asset Management • Strategic Planning of Storm System (Water Quantity and Quality) • Regulatory Obligations and Liability • Design Standards and Criteria • Establishing Levels of Service • Standard Operating Procedure • Operations and Maintenance • Monitoring • Watershed Protection • Flood Protection • Partnerships • Projects • Sustainable funding • Technical Support to other Departments and Divisions

Key Theme Areas of Work

1. Development of Watershed Management Principles/Policies

2. Flooding Preparedness and Response

3. SWM Quantity and Quality management for Regional Infrastructure

4. Development of Common Standards, Criteria, Guidelines, Levels of Service and Standard Operating Procedures

5. Sustainable Funding Program

6. Communications, Outreach and Education

7. Monitoring - Data Collection and Enhancement

8. Studies, Communications and Emergency Services

9. Governance

The following key theme areas of work have been identified:

Monitoring Program

Objectives of Interest: Evaluate whether LID SWM systems are

providing flood control, erosion control, water quality, recharge, and natural heritage protection as per the design standard.

Evaluate long-term maintenance needs and maintenance programs, and the impact of maintenance on performance.

Determine the life cycle costs for LID practices.

Demonstrate the degree to which LID mitigates urban thermal impacts on receiving waters.

Assess the ancillary benefits, or non-SWM benefits.

Improve and refine the designs for individual LID practices.

What is needed?

• Leadership by Example - the time is now to lead in a manner that allows municipalities to maintain

and enhance their stormwater responsibilities,

BUT at the same time enhance the relationship between

Regional and Local government and Conservation Authorities to take a

Watershed Approach
