Stormwater Master Plan: Area Thunder Bay’s watershed Lake Superior
Stormwater Master Plan: elements 1 2 4 3 WATERSHED NEEDS ESTABLISHING PROGRAM CHARACTERIZATION: IMPLEMENTATION: ASSESSMENT: GOALS & POLICIES: • physical conditions • issues identification • strategy for • retrofit opportunities stormwater mgmt. • drainage boundaries • evaluation of • ordinances & by-laws • policy changes existing infrastructure • natural features • CIP and O&M • climate change • standards for design • water quality rating • monitoring and development • map infrastructure • education/outreach • partnership/financing
Stormwater Master Plan: functions WATERSHED CITY HOME • facilitates maintenance of • facilitates protection & • promotes runoff reduction stormwater infrastructure restoration of natural by e.g. harvesting rainwater watershed functions • implements stormwater • improves water quality regulations for new- and • preserves ecological by e.g. practicing healthier re-development lawn care, picking up pet quality and function waste or using a car wash • provides stormwater • protects surface water management assistance & • promotes stewardship ethic /groundwater connections education to community resulting in healthier • maximizes network streams, rivers and lakes • anticipates future needs & of stakeholders builds system resiliency
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 process
Stormwater Master Plan: action items projects: hard-to-soft range of options typical pipe conveyance underground infiltration urban tree trenches typical culverts open infiltration trenches green roofs & raingardens
