Directed by the City of Thunder Bay with support from the Government of Ontario & with the financial support of the Government of Canada through the federal Department of the Environment

Project Introduction

City of Thunder Bay committed to the development of a Stormwater Master Plan in:

• 2008
• City of Thunder

Bay EarthWise Community Action Plan

• 2011
• City of Thunder Bay

2011-2014 Strategic Plan 2014 - Thunder Bay SMP to be developed funded by Environment Canada with the help of Emmons & Olivier Resources, Inc. (EOR)

Stormwater Master Plan: functions

WATERSHED CITY HOME

• facilitates protection &

restoration of natural watershed functions

• preserves ecological

quality and function

• protects surface water

/groundwater connections

• maximizes network
• f stakeholders
• facilitates maintenance of

stormwater infrastructure

• implements stormwater

regulations for new- and re-development

• provides stormwater

management assistance & education to community

• anticipates future needs &

builds system resiliency

• promotes runoff reduction

by e.g. harvesting rainwater

• improves water quality

by e.g. practicing healthier lawn care, picking up pet waste or using a car wash

• promotes stewardship ethic

resulting in healthier streams, rivers and lakes

Stormwater Master Plan: action items

20 Year Approach:

programs, policies and projects

programs:

• operations and maintenance
• combined sewer overflow
• conservation initiatives
• monitoring and analysis

policies:

• stormwater regulations
• design standards
• engineering and site plan review
