Stormwater utility projects

Suburbs

Our stormwater utility provides the funding for us to undertake important stormwater management projects across the city.

Some of our latest, current and upcoming stormwater management projects include:

Balzer Creek Project

Balzer Creek, a tributary of Schneider Creek, drains a watershed area of 259 hectares and is situated entirely within the city of Kitchener. The remaining "open channel" portion of Balzer Creek (that has not been buried and piped) has a length of 1.7 km and requires reconstruction, as it has experienced significant erosion over the past 30 years. Balzer Creek needs to be realigned because a portion of it has migrated overtop of a sanitary sewer, placing the city at risk for early replacement of this infrastructure.

Balzer Creek Environmental Assessment

In 2015, the city retained Ecosystem Recovery Inc. to complete the Balzer Creek Schedule 'B' Class Environmental Assessment (EA). The EA evaluated a variety of alternatives and presented preferred alternatives for creek restoration works and for the construction of a Type 2 multi-use trail (as outlined in the Multi-Use Pathways & Trails Master Plan, 2012). The proposed Type 2 multi-use trail will double as a maintenance access road for the sanitary sewer in the location adjacent to the rear property line of residents living on Brisbane Court and Brisbane Drive.

Grand River Erosion Control

Erosion and slope stabilization issues adjacent to Grand River Boulevard are a focus area for us. Over the past few years, we've determined remedial work - in addition to the recommendations included in an original environmental assessment conducted by the Grand River Conservation Authority (GRCA) - is required in the area. Final design work is underway.

The following files make up the addendum to the original environmental assessment:

Hidden Valley Creek Watershed 

In 2015, the city completed a hydrologic and hydraulic modelling study of the Hidden Valley Watershed. The purpose of this study was to develop an understanding of the root causes of the existing erosion and flooding of the creek and to gain insight into the best options for mitigating these impacts. The study provided analysis of the proposed River Road Extension and associated developments. Specific objectives of this study included the mitigating of stormwater management criteria for the watershed and recommendations for upgrades to the existing culverts under Hidden Valley Road.

Idlewood Creek Restoration Project

The City of Kitchener is proceeding with improvements to Idlewood Creek, at three site locations between Fairway Road and the creek's outlet to the Grand River. This project includes:

  • the removal of two dam structures and two culvert crossings, and,
  • a gabion-lined channel outlet to the Grand River.

The project will use natural channel design to reduce erosive processes, improve fish passage, and maximize fish habitat potential in the locations of the proposed dam removals. In addition to the proposed natural channel works, an important trail connection will be made to the Walter Bean Trail from Edgewater Crescent through Site 3 and is considered a high priority for the City of Kitchener's Multi-Use Pathways and Trails Master Plan (2012).

In 2016 The City of Kitchener undertook a Municipal Class Environmental Assessment (EA) to assess alternatives for improvements within this section of Idlewood Creek. In 2016, the City of Kitchener acquired the property at 155 Woolner Trail (Site 3) in anticipation of this work and to allow the recommended solutions in the EA to begin. The benefits of this work will include improvements to aquatic and terrestrial habitat conditions, to the stability of the creek, and improvements to water quality discharging into the Grand River.

The Idlewood Creek restoration project will coordinate both the new channel configuration and trails into new and existing park areas. Construction is anticipated to start in the summer of 2018.

Retrofit of Stormwater Management Facility (SWMF) 66

In 2011, the City of Kitchener completed a Municipal Class Environmental Assessment (EA) to assess alternatives for improvements at SWMF 61, 65 and 66 and their associated channels. The goal of the EA for SWMF 66 was to provide a preferred solution to install water quality control and restore the historic wetland located within the facility.

A public open house was held on March 9, 2011, to introduce the project and to get input from the public. After the EA was completed, the city retained a consultant to prepare a design of the preferred solution identified in the EA. The drawings and design summary were provided to the city as "Issued for Approval."

In 2016, the City of Kitchener retained a consultant to finalize the design and provide construction administration services for the retrofit of the facility.

Another open house took place July 6, 2017, at the Country Hills Community Centre, 100 Rittenhouse Rd., Kitchener, to present the final design to the public before construction began.

Rothsay Avenue overflow sewer and Forfar Park wetland retrofit

A class environmental assessment detailed design for Kolb Creek has been completed; construction is now underway. When the project is complete, there will be a new overflow storm sewer on Rothsay Avenue from Kolb Creek to Matthew Street, upgrades to the stormwater facility in Forfar Park, and trail improvements in the project area.

Schneider Creek remediation

The GRCA completed a class environmental assessment for the portion of Schneider Creek between Hayward Avenue and Manitou Drive to determine required remedial flood control measures to mitigate flooding and erosion.

Since that time, we have prepared an addendum to the original assessment and sought community input on the project through, for example, a public information centre featuring display boards that outlined our proposed work.

Stormwater Management Facility 10 retrofit

Stormwater Management Facility (SWMF) 10 is located near Lackner Boulevard (Regional Road 54) and Zeller Drive. It is located adjacent to the Idlewood Creek Provincially Significant Wetland (PSW) Complex and forms part of, and drains through the North Branch of Idlewood Creek.

In 2010, The City of Kitchener undertook a Municipal Class Environment Assessment (EA) to assess alternatives for improvements at 12 ponds including SWMF 10. The intent of the EA for SWMF 10 was to retrofit the dry pond to a wet pond to incorporate enhanced water quality control. Detailed design was completed in 2011 and the project was put on the hold to accommodate for higher priority projects.

The city recently completed an Integrated Stormwater Management Master Plan (2016) and SWMF 10 was identified as a high priority retrofit project due to the need for major reconfiguration on the facility's outlet, and insufficient storage volume to provide water quality control.

 Stormwater Management Facility 21 partial retrofit

In 2010, the City of Kitchener undertook a Municipal Class Environment Assessment (EA) to assess alternatives for improvements at 12 ponds including SWMF 21. The goal of the EA for SWMF 21 was to identify ways to:

  • Incorporate water quality control features to meet the Ministry of the Environment and Climate Change, and City of Kitchener standards;
  • Improve operations and maintenance activities by preventing persistent clogging of the outlet; and,
  • Ensure that existing flood control storage was maintained.

Using the recommendations identified in the EA, a detailed design was completed in 2011; however, the project was put on hold to accommodate higher priority projects.

In 2016, the city completed an Integrated Stormwater Management Master Plan – Implementation Plan (ISWM-MP), prioritizing pond retrofits (upgrades) which had yet to be completed. The retrofit works for SWMF 21 were identified as a high priority retrofit project. To meet the objectives listed above, the upgrades will include:

  • Installation of a forebay and a plunge pool;
  • Construction of a new facility outlet;
  • Construction of two (2) maintenance access roads; and,
  • Landscape restoration of all disturbed areas as a result of construction.
