1 City of Kitchener Integrated Stormwater Management Master Plan (ISWM-MP) Public Open House No. 2 April 28, 2016

2 Open House Format min presentation Facilitated questions and answer session following the presentation Open viewing format discussion with City staff and the project team Two (2) zones: 1. Information Zone 2. Ideas Zone INFORMATION ZONE IDEAS ZONE

3 Information Zone What is it? INFORMATION ZONE The INFORMATION ZONE provides an opportunity for you to review the study process and outcomes. Boards present the identified stormwater opportunities within various neighbourhoods of the City. Recommended Approaches for: Pollution Prevention, Municipal Management and Operation Practices Source Control and Market Strategies Conveyance Control and The Municipal Right-of-Way (ROW) Stormwater Management Facilities Stream System Understanding and Erosion Storm Sewer Infrastructure

4 Ideas Zone What is it? The IDEAS ZONE provides an opportunity to share your vision and ideas for improving SWM in your neighbourhood: design and 'look' of SWM features in your neighbourhood other measures to reduce runoff and enhance your neighbourhood IDEAS ZONE Share with us: what can be done on your property to help reduce runoff and flooding while beautifying your landscape

5 Study Process Where are we in the study process? WE ARE HERE Open House #2

6 What is a Master Plan? A stormwater Master Plan is a longterm planning document which follows the Environmental Assessment (EA) Process This study follows Approach #2 of the MEA Municipal Class Environmental Assessment Process (2011) and fulfills: Schedule A, A+, and B projects and identifies any Schedule C projects for future studies

7 When will Construction Start? The identified opportunities within the Master Plan will be implemented over the next 15 years. Further public consultation will be undertaken for each individual project as part of detailed design.

8 Study Purpose Municipal Class Environmental Assessment Process for Master plans updates the existing 2001 Stormwater Management (SWM) Policy Enables the City to identify opportunities and be proactive in addressing stormwater issues before they become a problem Establish SWM guidelines and policies for the next 15 years Prioritizes works and allows for more efficient expenditure of existing and proposed SWM funding

9 Problem Statement Urban areas can degrade the environment in many ways, as a result of both new development and from existing development: Degraded water quality Increased stream temperatures Increased sediment loads Loss & degradation of habitat Flooding (rivers) Erosion Urban flooding Hidden Wards Fairview Valley & Brigadoon Mall Failure

10 Study Goals & Objectives An Integrated SWM Master Plan considers flood and erosion control, groundwater and surface water quality, environment management and infrastructure, all in an integrated manner. Urban runoff Infiltration to Groundwater Grand River Waste Water Treatment Plant Drinking Water

11 Study Goals & Objectives Goals & Objectives established for: Water Quality Water Quantity Erosion Control Natural Environment Water Resource Infrastructure Policy & Implementation Community

12 Existing Conditions Existing conditions were characterized through a background review and field investigations. They are summarized in an Existing Conditions Report (April, 2015) Stormwater Aquatic Terrestrial Water Stream Quality Ecology Management Health Ecology

13 Studies & Opportunities Assessed and developed SWM opportunities relating to: 1. Pollution Prevention, Municipal Management and Operational Practices 2. Source Control and Market Strategies 3. Conveyance Control and Roads (Municipal Right-of-Way) 4. Stormwater Management (SWM) Facilities 5. Stream System Understanding and Erosion 6. Storm Sewer Infrastructure Project locations, evaluation criteria & projects details are displayed in the INFORMATION ZONE INFORMATION ZONE

14 Pollution Prevention, Municipal Management and Operational Practices Will ensure that pollutants are prevented from impacting the environment and that existing stormwater infrastructure maintain their effectiveness. Key elements of the recommended strategy include: Sediment removal from catch-basins Immediate maintenance of sixteen (16) Oil and Grit Separators and the continued maintenance of all OGS units per the recommended schedule.

15 Source Control & Market Strategies Kitchener Homeowners & Business the City intends to evaluate and determine the appropriateness of a variety of incentives and programs: Financing Options Bonusing Strategies Review Enhancements Service Charge Reductions

16 Source Control & Market Strategies BEFORE AFTER This landscape reduces runoff, absorbs rainwater, improves water quality, and requires less irrigation.

17 Conveyance Control & Roads As part of capital road reconstruction projects (per the Infiltration Policy), the City intends to implement linear stormwater systems located within and adjacent to roadways to encourage infiltration of water into the ground, improve water quality and reduce runoff. Bioretention (rain garden) Bioretention (turf)

18 Conveyance Control & Roads

19 Stormwater Facilities To manage the City's existing stormwater facilities and maintain their effectiveness, the city intends to: Retrofit ten (10) previously identified Stormwater Management Facilities Remove sediment from 16 Dry facilities and 27 Wet facilities Construct twelve (12) new stormwater facilities as part of park rehabilitations

20 Stormwater Facilities Example: Retrofit (Pond 4) AFTER BEFORE

21 Stormwater Facilities Example: New SWM Facility & Park Rehabilitation BEFORE AFTER Playground (splash pad) Soccer field (Subsurface Facility) Pond

22 Streams & Erosion Stream Types: Examples in Kitchener Schneider- Doon Village Schneider- Balzer Rd Schneider- Hallman Park Henry Sturm- West Ave Detweiler Bankside Dr M. Strasburg Huron Rd

23 Streams & Erosion Issues: Examples in Kitchener

24 Streams & Erosion Following the stream erosion assessment and to improve the environmental form and function of local watercourses, the City intends to undertake the restoration of: Erosion sites Stream reaches

25 Streams & Erosion Example: Stream Restoration: Filsinger Park

26 Storm Sewer Infrastructure Trunk Sewers, 600mm and larger were modelled (6,000 pipes) Five (5) Scenarios were evaluated from Existing Conditions to Climate Change Conditions Existing Conditions Climate Change

27 Storm Sewer Infrastructure Following the development of the storm trunk sewer network model, and identification and assessment of the capacity of the existing SWM ponds, the City intends to expand the sewer network model in areas identified for future study to evaluate and select the preferred remedial approaches

28 Study Next Steps Community and Infrastructure Services Committee (May 30, 2016) Council (June 2016) followed by filing of the Master Plan EA for 30 day public review Implementation plan (under separate cover) will be developed over the summer months

29 Implementation Next Steps Following the implementation plan and prior to construction, the City will be undertaking the following steps over the coming years: 1. Allocating funding for future works over the next 15 years. 2. Undertaking Individual Schedule C Class EAs. 3. Obtaining necessary environmental approvals. 4. Undertaking public consultation for individual projects. 5. Develop detailed designs.
