Box 1118 Kitchener, ON N2G 4G7 Date: September 23, 2008 To: Members of Heritage Kitchener Committee From: Leon Bensason, Coordinator, Cultural Heritage Planning cc: Subject: Victoria Park Lake EA The City is overseeing a Class Environmental Assessment (EA) to identify a preferred option to address the water quality in Victoria Park Lake. Heritage Planning staff have been appointed to the Steering Committee to address cultural heritage interests. Please find enclosed background material regarding this project. A Public Information Meeting was held on Thursday evening, September 25th at the Victoria Park Pavilion. Previous notice of this meeting was forwarded to Heritage Kitchener members by e -mail. Staff will provide the Committee with an update regarding this EA at the October 7th meeting. TECHNICAL MEMORANDUM CH2MHILL Project Objectives & Alternatives for Evaluation PREPARED FOR: Victoria Park Lake Public Advisory Committee (PAC) PREPARED BY: CH2M HILL & Stantec DATE: July 17, 2008 Problem Statement The Lake in Victoria Park was created over 100 years ago and has become an important recreational resource for the City of Kitchener. Stormwater collected from neighbourhoods upstream is conveyed through the lake. Sediments conveyed by the stormwater accumulate in the lake and have been removed every 12 to 15 years. Water quality in the lake continues to be a concern, and has restricted the enjoyment of the lake and surrounding park area particularly during the summer period. The City now wishes to explore alternatives to address both the accumulation of sediment and the quality of water in Victoria Park Lake through a Class Environmental Assessment study. The study will follow the requirements for a Schedule B project under the Municipal Class Environmental Assessment (October 2000, as amended in 2007). Project Objectives The City of Kitchener recognizes the importance of Victoria Park and in recent years developed the Victoria Park Strategic Plan. This plan calls for a detailed watershed study and environmental assessment to help with deciding on the best solution to the lake's water quality and sedimentation problems. The objectives of this project are: • To determine a preferred option for Victoria Park Lake and its watershed with respect to water quality and sediment accumulation, while taking into account: — Hydrology and hydraulic capacity — Flood control — Aquatic habitat — Operations and maintenance — Aesthetics — Safety — Social and recreational uses • To carry out a Class Environmental Assessment • To complete a preliminary design for the preferred option Alternatives for Evaluation An important step in the Class Environmental Assessment (EA) process is the identification of Alternative Solutions to the problem as defined in the Phase 1 Needs Statement. The Municipal Class Environmental Assessment June 2000, as amended in 2007, defines "Alternative Solutions" as: "feasible alternative ways of solving an identified problem (deficiency) or addressing an opportunity, from which a preferred solution is selected ". The Do Nothing alternative must be considered in the Class EA assessment process as a baseline condition against which alternative solutions are evaluated. Alternatives which will be evaluated to come up with the preferred solution have been divided into two categories; lake -based options and upstream options. Upstream options will be examined for each contributing tributary separately to determine the best solutions for each individual area of the upstream watershed to improve the sediment and water quality in the lake. The evaluation will look at the upstream options and the lake based options in parallel with findings from each evaluation feeding into the parallel process to determine the cumulative benefits that can be realized and to develop the best solution to achieve the project objectives. This process is shown visually in Figure 1. FIGURE 1 Evaluation process flow diagram The list of the lake -based and upstream alternatives with a brief description of each is provided below. Lake -Based Alternatives Do Nothing - This alternative would see Victoria Lake left in its current condition and no extraordinary measures implemented to improve existing conditions. • Maintain existing Lake Configuration and Dredge Sediments - In this alternative, the sediments in the existing lake would be dredged (and properly disposed) to improve current lake conditions. The Lake would remain in its current configuration. No additional measures to sustain or improve water quality would be implemented. • Reconfigure Lake and Improve Function - This alternative would see the sediments in lake dredged (and properly disposed) and then additional measures taken to improve the circulation of water in the lake to improve the water quality. Measures may include reconfiguring the surface area of the lake and /or changing the depth of the lake. • Take Lake offline - In this alternative, a bypass creek /greenway channel would be constructed around the existing lake. Sediments in the lake would be dredged (and properly disposed). During normal low flow conditions in the upstream creeks, most of the flow would be conveyed through the new channel and a portion of the flow would be diverted to the lake to maintain lake function. Under high flow conditions (such as storm events or spring melt) when sediment loading may be greater, all the flow from upstream watercourses would be conveyed around the lake through the by -pass channel. • Remove Lake and Reconfigure Channel - In this alternative the lake would be removed from the system (by removing the lake outlet structure) and a new creek /greenway channel would be constructed to maintain a functioning creek / greenway system with associated strearnbanks and floodplain habitats. Upstream Creek /Greenway Alternatives • Do Nothing - This alternative would see the existing upstream system left in its current condition. No extraordinary measures would be implemented to improve upstream creek /greenway conditions. • Implement Source Control Options - A variety of source control options are available to improve stormwater quality management such as on -lot runoff reduction, street sweeping and cleaning, parking lot cleaning, sanitary sewer cross connection (to the storm sewer) reduction etc. • Implement Conveyance Control Options - A variety of conveyance (pipe) control options are available to improve levels of stormwater quantity management such as infiltration storm sewers, catchbasin cleaning etc. • Implement End -of -Pipe Control Options - A variety of end -of -pipe control options are available to improve levels of stormwater quantity and quality management such as stormwater management detention facilities, enhanced stormwater management facilities (e.g. continuous deflection separators etc.), wetlands etc. • Implement Creek/Greenway Restoration Measures - A variety of stream restoration measures are available to improve levels of stormwater quantity and quality management through improvements to creek /greenway morphology and to habitat conditions.

Detweiler Greenway What you can do to help.- • Be certain that any proposed work near your property boundary and a watercourse does not represent an encroachment into the watercourse. If in doubt contact City Staff. • Avoid littering and /or dumping material such as yard waste, lawn clippings and garbage in or near a watercourse. • Pick up after your pet. • Avoid draining swimming pools directly into a watercourse as the chemically treated water can be detrimental to aquatic habitat, fish and wildlife. • Choose low maintenance landscaping to minimize the need for water and fertilizers. • Avoid dumping cleaners, paints and chemicals down sewers. • Volunteer for a Stream Clean Up event. • Organize a Yellow Fish Road Program in your neighbourhood.
