TECHNICAL MEMORANDUM: REVIEW OF ALTERNATIVE STAGING AREAS FOR SITE 5
December 9, 2014
1.0 Introduction
The purpose of this technical memorandum is to document a review of potential alternative staging areas in Stanley Park. On October 20, 2014, a site walkthrough was conducted with representatives from the NCC (Mathieu Brisson and Julie Mulligan), City Forestry and City Parks. The following major comments were received from the NCC during the site meeting:
• Mitigate impacts on the recently reforested area to the extent practical.
• Prioritize the protection of willows, maples (except Manitoba Maples) and pines.
• Do not eliminate the dog park area.
• Extend the staging area for the main shaft further south to protect the recently reforested area.
• Save the preferred trees identified during the site visit to the extent possible.
• Staging is permissible in the existing treed area around and northeast of the IOS Connection Chamber as this area would benefit from renewal.
Staging area alternatives were developed in an attempt to address these comments to the extent practical. These options were submitted to the NCC with a discussion email and request for comments on November 12, 2014. The NCC subsequently requested on November 20, that a technical memorandum be provided to formalize the submission of information and include a table of advantages and disadvantages.
2.0 Staging Area Alternatives
This section describes the staging area that was included in the 70% design submission and also describes two alternatives staging areas developed in an attempt to reflect some of the preferences identified by the NCC in order to save more of the reforestation area in the west. Note that the property boundaries and ownership are indicated on the appended drawings.
The three staging areas evaluated include the staging area layout as per the 70% design, alternative 1 (shifting south and east) and alternative 2 (encroaching into a portion of the dog park). Tunnel launch operations require significant space, particularly when pressurized face tunnel boring machines (TBM) and precast segments are being installed, which is the case for this project.
For all options, a portion of the Rideau River Eastern Pathway would be temporarily closed south of Queen Victoria Street. A temporary paved link would be constructed between the end of Queen Victoria Street and the Rideau River Eastern Pathway for continuing north along Stanley Park. The alternative to taking the paved path to Queen Victoria Street and Stanley Avenue would be for park users to take the granular surface pathway that follows the river’s edge to New Edinburgh Park.

TECHNICAL MEMORANDUM: REVIEW OF ALTERNATIVE STAGING AREAS FOR SITE 5
December 9, 2014
70% Design Staging Area
The tunnel launch construction staging area presented to the stakeholders as part of the 70% design is outlined in blue in Exhibit 1. It is approximately 0.6-0.7 hectare, straddling property owned by the City of Ottawa, the National Capital Commission (NCC) and the Ministry of Natural Resources and Forestry (MNRF). There are two separate staging areas for the work done in the park. The primary staging area to the south of the park (referred to as Site 5a) is for the CSST tunnel launch operation and the construction of the CSST outlet structures. This is where the CSST will terminate and flow into the existing Interceptor Outfall Sewer (IOS – the existing trunk sewer flowing to the sewage plant). The secondary staging area to the north (referred to as Site 5b) is for the launch of a smaller tunneling machine (micro-tunnel boring machine - MTBM) to construct a diversion sewer that will connect an existing outfall sewer on River Lane (Site 5c) to the CSST chamber in Stanley Park (Site 5a). There will be a shaft for the launch of this MTBM for construction purposes and, ultimately, there will be a permanent maintenance hole that will be constructed in the location of this temporary shaft.
The primary staging area (Site 5a) could be occupied for 18-24 months, which includes the site preparations, excavation of the shaft tunneling and construction of the chambers. The range in duration depends on the contractor’s proposed tunneling operation. However, it is expected that the north staging area (Site 5b) would be required for a much shorter period, in the range of 6-8 months. The length of tunneling to be advanced along the CSST alignment from this site is 2 km if Site 3c at Nicholas and Laurier is also used as a launch site, which is expected. Otherwise, a 4-km tunneling length would be advanced from Stanley Park, which would more than double the duration of the tunneling component of the works. For the diversion sewer, it is expected that there would be two separate launches from the same pit at Site 5b. One to tunnel from Site 5b to the CSST at Site 5a, and the second to tunnel from Site 5b to Site 5c at River Lane. The total length of the diversion sewer will be 265 m. The MTBM to be used for the diversion sewer advances in straight lines, while the main TBM to be used for the CSST can follow a curved alignment. The staging area as presented in the 70% design submission is illustrated on the appended drawing 5-L01 (blue outline).
Staging Area - Alternative 1
The intent of Alternative 1 is similar to that of the 70% design, except that it protects more of the recently reforested and capped area west of the tunnel launch shaft. As discussed on site, the staging outline is pushed further southeast, right up to a stand of mature trees and also north of the IOS connection chamber, where the trees are near the end of their lifespan. The east boundary of the staging area was identified in the field with the NCC where higher quality trees in better condition were observed. As recommended by the City and supported by the tunnel designers for better site efficiency, the two staging areas are proposed to be connected as illustrated. The staging area for Site 5b (north portion) and the link between the two would be reinstated after the 6-8 month construction period for the diversion sewer and chamber. The Alternative 1 staging area is illustrated on the appended drawing 5-L02 (red outline).

TECHNICAL MEMORANDUM: REVIEW OF ALTERNATIVE STAGING AREAS FOR SITE 5
December 9, 2014
Staging Area - Alternative 2
The intent of Alternative 2 is to locate some of the staging in a portion of the dog park northwest of the surge tank behind the recent reforestation area, while still preserving part of the dog park. This option protects the reforestation/capping area to the greatest extent and has the advantage of configuring the best usable space for staging, as it is one continuous area. The Alternative 2 staging area is illustrated on the appended drawing 5-L03 (green outline). Not shown on this exhibit is the remaining portion of the dog park space west of the staging area (cut-off the image). As previously indicated, it is expected that the MTBM tunneling for the diversion sewer and the maintenance hole installation at Site 5b will take approximately 6-8 months. Therefore, the northern part of the staging area would only be required for that period, after which the hoarding would be relocated and the north portion would be reinstated.
Environmental Considerations Large portions of the NCC property and part of the City property in Stanley Park was capped due to the presence of constituents in surface soil at concentrations potentially posing unacceptable risk to human health. It is suspected that portions of Stanley Park may contain waste or landfill material. Fill material throughout the park is of variable composition and in some test locations was noted to contain brick, wood, concrete and organics. The alternative staging areas would reduce impacts on the capped areas.
3.0 Evaluation of Options Exhibit 1 presents advantages and disadvantages for the various staging areas considered.
Exhibit 1: Evaluation of Alternative Alignments
70% Design Staging Area
Advantages
• Least impact on large/mature trees.
• Least impact on the Rideau River Eastern Pathway.
• Least impact on usable park areas and dog park.
Disadvantages
• Greatest impact on newly planted trees.
• Greatest potential impact on capped contaminated areas.
• The two staging areas are not connected
Alternative Staging Area 1 (moved southeast and northeast)
Advantages
• Approximately 60-70% less impact on newly planted and capped soil areas.
• More “preferred” trees are protected (maples, pines, willows, etc).
• Dog park is little impacted.
• Two staging areas are connected.
Disadvantages
• Still impacting portions of the newly planted and capped soil areas.
• Greater impact on mature treed areas.
• Stanley Park bisected into two areas for a period of 6-8 months by the interconnection of the two staging areas.

December 9, 2014
Alternative Staging Area 2 (part of dog park )
Advantages
• Least impact on newly planted and capped soil area (most newly planted trees are protected).
• Less impact on mature treed areas than Alternative 1.
• More “preferred” trees are protected (maples, pines, willows, etc).
• One single staging area – most efficient.
Disadvantages
• A portion of the dog park is used for the staging area.
• Stanley Park bisected into two areas for a period of 6-8 months by the combined staging area.
4.0 Summary & Conclusion
The above evaluation compares two alternative staging area plans to the plan that was presented as part of the 70% design submission. The alternative options reduce the impacts on the newly planted and capped soil areas and protect all but one of the “preferred” trees identified during the October 20 walkthrough with the NCC. Only one maple tree located at the diversion sewer shaft cannot be protected (tree # 38 on the appended maps). Alternative 2 (in green) is the City’s preferred option for constructability, efficiency of space and safety. It presents one continuous staging site and has the least impact on newly planted and capped soil areas, while the only mature trees impacted are ones deemed by the NCC to benefit from renewal.

Good Morning
Construction of the tunnel under the bed of the Rideau River does not require Notice to the Minister or review of the work considering that the method of construction does not require placement or use of any work in the waterway. If there is to be any work (temporary or permanent), a Notice of Work is to be submitted for review. I have attached the mandatory Notice of Works form for your convenience.
In the case of the outfall, it is possible that it may be considered a Minor, or “designated work”. Please assess your outfall project against the attached info sheet. If the project can meet all the terms and conditions on this sheet, it can be considered minor and Notice to the Minister is not required. If the project cannot meet all of the terms and conditions that are outlined on the form, a Notice of Works is required for review prior to the commencement of any construction.
Please contact us if you have any further questions.

Stantec is currently completing the design of the Combined Sewage Storage Tunnel (CSST) project for the City of Ottawa. The CSST project includes a tunnel that will pass underneath the Rideau River (approx. 9 to 10 m below the riverbed) and underneath the Rideau Canal (approx. 16 m below the canal bed). The CSST project also includes extension of an existing outfall to the Ottawa River. We have regular (monthly) progress meetings in Ottawa on this project and would like to extend the invitation to a representative of Transport Canada. Can you advise who I should contact at Transport Canada? Also, we would like to obtain information on the requirements for an outfall with respect to the Navigation Protection Program. Depending on the design of the outfall, as I understand, it may or may not be considered a minor work. However, even if it is a minor work, there may be conditions or requirements of Transport Canada to maintain navigation safety. Does Transport Canada have any guidance on what those conditions may be? Any direction you can provide would be appreciated. Thank you, Loretta Hardwick, M.Sc.

Combined Sewage Storage Tunnel Project Information
Ottawa River Action Plan Project No. 3
June 2012 1
1 Background The Combined Sewage Storage Tunnel (CSST) Project is one of 17 projects of the Ottawa River Action Plan. The City’s combined sewer areas drain to the Interceptor-Outfall Sewer (IOS). Combined sewers collect and transport sanitary wastewater and stormwater runoff in a single pipe. In dry weather, an interceptor sewer, such as the IOS, captures all of the wastewater flow from the combined sewers and carries it to the wastewater treatment plant. A regulator is a control structure that normally directs sewage from a combined sewer to an interceptor; in wet weather it directs excess combined sewage to a local water body in order to prevent overloading of the interceptor and/or treatment plant and basement flooding. This is called a combined sewer overflow (CSO). Thousands of cities such as London, Paris, New York, Montreal, Toronto, Kingston etc., have combined sewers and CSOs. Frequent and large CSOs to the River have been identified at three locations: the West End Regulators (Cave Creek and Booth) in the Lebreton Flats area, the Rideau Canal Regulator and the Keefer Regulator. These regulators and the Interceptor-Outfall Sewer (in red) are shown below.
Extensive public consultations held in late 2009 during development of the Ottawa River Action Plan showed that there was a strong desire to limit the

frequency of overflows beyond the provincial target of 2 overflow events during the swimming season of the so-called “Design Year”. The public did not expect complete elimination of CSOs, which is considered unaffordable, but showed strong support to go beyond the provincial target of two overflow events to zero overflow events during the swimming season of the “Design Year”. In February of 2010, City Council instructed staff to achieve this target, with the understanding that there would continue to be overflows during rainfall events that are larger than those of the “Design Year”. Through development of the Ottawa River Action Plan and the Combined Sewer Area Pollution Prevention and Control Plan, it was determined that the best option to achieve this control target would be to build one or more facilities to store excess combined sewage that would otherwise overflow to the River. When wet weather subsides, the stored sewage would then be returned to the sewer system and from there to the City’s wastewater treatment plant for treatment.
2 Environmental Assessment and Functional Design This project is being planned as a Schedule C project in accordance with the requirements of the Municipal Class Environmental Assessment, 2007. The Municipal Class EA is divided into five Phases.
2.1 Environmental Assessment In early 2010, Stantec Consulting Ltd. was hired to complete the Environmental Assessment and Functional Design for the CSST Project. The project is currently nearing the end of Phase 3 (evaluating alternative designs for the recommended preferred alternative solution) and beginning to draft the Environmental Study Report (Phase 4) of the Class EA process, and the functional design is almost complete. The EA phases are summarized schematically on the next page, along with dates when the CSST project reached key milestones.
2.2 Public and Stakeholder Consultation Public consultation took place twice during Phase 2 at the following project milestones, in accordance with the Class EA process: March/April 2010: presentation of a long list of alternatives, the evaluation
criteria and the evaluation methodology. This long list included underground tank options, tunnel options, combinations of tanks and tunnels and in-River Storage.
June 2010: presentation of the short list of alternative solutions being considered, the evaluation of the alternative solutions and introduction to the recommended preferred alternative solution.

These milestones were also the subject of communications (emails, and/or phone calls, and/or meetings) with potentially affected stakeholders and other interested parties. One opportunity for public consultation has been planned during Phase 3, which is the current point of the project as previously mentioned. A public open house is being planned for June 26th 2012 at City Hall and will include presentation of alternative design concepts for the recommended preferred alternative solution. Public comments are being collected throughout the study including open houses in accordance with the Class EA Act, and become part of the public record (with the exception of personal information).
2.3 Recommended Preferred Alternative Solution The recommended preferred alternative solution consists of three major components to be implemented in two phases: Phase 1:
o a Core Tunnel, linking the West End Regulators in Lebreton Flats, the Rideau Canal Regulator and the Keefer Regulator
o a North-South tunnel along Kent Street, interconnected to the Core Tunnel at or near Slater

Phase 2: o an East Tunnel from Keefer Regulator to the Robert O. Pickard
Environmental Centre Together, the two Phase 1 tunnels provide sufficient storage to achieve the mandated CSO control targets. They total over 6km and have an inner diameter of 2.4 to 3.0m. The alignment of both tunnels is shown in the figure at the end of this document. Preliminary planning-level cost estimate for Phase 1: $115 to $150 Million. The implementation schedule is discussed below under “Next Steps”. During rare, extreme weather, the North-South tunnel component can also be used as a major flood-relief pipe to channel excessive runoff away from flood-prone areas to the Ottawa River. Phase 2 will provide even more storage and therefore further improve CSO control, and will also greatly enhance system redundancy and operational flexibility. This element cannot be constructed with the currently available funding; it will be constructed when funding is available.
2.4 Functional Design The functional design is almost complete. Its purpose is to define the form, function, size, preliminary location and planning-level cost estimates of major components of the twin-tunnel solution, such as:
the tunnels entry/exit points and staging areas for tunnel boring machine(s) flow diversion and structures and regulators flow diversion sewers odour control facilities modifications to existing sewers and regulators high-level operating strategy and integration with the City’s Real-Time
Control system
Population intensification and climate change have been considered in the functional design, in addition to the usual factors such as known geotechnical constraints, conflicts with other utilities and buildings, conflicts with LRT, constructability, etc.

3 Next Steps Subject to prompt and successful completion of discussions between the City and Federal Departments regarding the use of Federal lands for some components of the project, the project’s Environmental Assessment and Functional Design could be completed by late summer 2012. Estimates of the time needed to complete the next steps of the process are presented below:
Preliminary & Detailed Design .......................................................... Q1/2013 Tendering and Contract Award ......................................................... Q3/2014 Construction ..................................................................................... Q1/2015 Commissioning ................................................................................. Q3/2017
The timeline above is to be read with caution given the complexity and scope of this project and the inevitable uncertainties that are to be expected at this stage.
