hired The Municipal Infrastructure
Executive Summary: The City of Pickering p
Group Ltd. in November 2012 to undertake the Krosno Creek Flood Reduction Study,
formerly called the Kronso Creek Diversion Study, which was a priority project identified
in the Frenchman's Bay Stormwater Management Master Plan (Master Plan) to reduce
flood risk to properties located with the Krosno Creek watershed. The Krosno Creek
Flood Reduction Study determined that the preferred solution to mitigate the flooding in
Krosno Creek is to replace the existing culverts at Alyssum Street, Reytan Boulevard
and Morden Lane with twin 3.0 m wide x 1.8 m high concrete box culverts. The
recommended culvert improvements will reduce the number of potentially flood prone
buildings in a 100 year return period storm from 64 to 8.
The erosion control of Krosno Creek was also listed as a project in the Master Plan. The
remaining natural reaches of Krosno Creek, south of Reytan Boulevard to Sandy Beach
Road, are experiencing significant erosion of the valley walls due to the large flows that
have resulted from urbanization of the watershed and from the more intense storms that
have been occurring over the last few years. The channel has shown signs of planform
movement and downcutting over time, and may threaten private properties through the
erosion processes in the near future.
Engineering & Public Works staff requested a fee proposal from The Municipal
Infrastructure Group Ltd. for this assignment due to their project history with the Krosno
Creek Flood Reduction Study, their knowledge and expertise, and on the basis that
good value would be achieved since they have all the background information from the
previous assignment.
In accordance with Purchasing Policy 10.05 where the project or annual cost of a
consulting or professional service assignment is expected to be more than $30,000.00
and the initiating Director intends to acquire the services without obtaining written
proposals, the Director shall submit a Report to Council to obtain approval to engage
the services of a particular consultant. Staff are recommending Council approval of the
fee proposal submitted by The Municipal Infrastructure Group Ltd. for Consulting and
Professional Services for the Detailed Design of Culverts and Erosion Control for.

expected to commence in 2016, subject to budget approval.
Discussion:
•
Council endorsed the Frenchman's Bay Stormwater Management Master Plan
On April 19, 2010, Council endorsed the Frenchman's Bay Stormwater Management
Master Plan (Master Plan) and authorized City staff to implement the recommendations
of the Master Plan subject to budget and further Council approval for individual projects
(Resolution #72/10). The overall goal of the Master Plan is as follows:
"To address long-standing concerns regarding the ongoing decline in the quality of the
Frenchman's Bay ecosystem by seeking means to control the quantity and quality of
storm runoff entering the local creeks and the Bay itself."
The recommended Master Plan consists of a suite of projects, programs and policies
designed to address issues related to flooding, erosion and poor water quality in
Frenchman's Bay and its' tributary watersheds. The Master Plan addressed Phases 1
and 2 of the Municipal Class EA process and more detailed investigations are required •
at the project-specific level in order to fulfill the Municipal Class EA documentation
requirements for the specific Schedule B and C projects identified within the Master
Plan.
The Krosno Creek Flood Reduction Study, was a priority, project identified in the Master
Plan to reduce flood, risk to properties located with the Krosno Creek watershed. Krosno
Creek Erosion Control was also a project that was listed in the Master Plan as a
required erosion control project, as the remaining natural reaches of Kronso Creek are
experiencing significant erosion of the valley walls due to the large flows that have
resulted from urbanization of the watershed from the more intense storms that have
been occurring over the last few years. The channel has shown signs of planform
movement and downcutting over time, and may threaten private properties through the
erosion processes in the near future. Staff have had to perform emergency erosion
works within the last five years, due to the public safety concerns. Recently, a resident
who borders the creek has contacted staff with their concern of losing vegetation and
land due to the erosion and are worried about the length of time to get the permanent
erosion control works in place.
The Krosno Creek Flood Reduction Study Environmental Assessment was
completed in February 2015 .
In November 2012, Council authorized the hiring of The Municipal Infrastructure Group
Ltd. through a competitive process, to undertake the Krosno Creek Flood Reduction
which was completed February 2015, in
Study Class EA (Resolution #140/12 , wh p ry ,

accordance with the Schedule B process as outlined in the Municipal Engineers
Association Municipal Class Environmental Assessment (Class EA) (October 2000, as
amended.in 2007 and 2011) and received Ministry of Environment and Climate Change
approval in March 2015.
This study was undertaken to establish the most effective means.of protecting people
and property from flooding in the Krosno Creek watershed. As part of the study, the.
• existing natural, cultural, socio-economic and engineering environments were
inventoried.
The Krosno Creek Flood Reduction Study Class EA determined that the preferred
solution to mitigate the flooding in Krosno Creek is to replace the existing culverts at
Alyssum Street, Reytan Boulevard and Morden Lane with twin 3.0 m wide x 1.8 m high
concrete box culverts.The recommended culvert improvements will reduce the number
of potentially flood prone buildings in a 100 year return period storm from 64 to 8.
Detailed field investigations were completed and preliminary designs were prepared for
the recommended culvert replacements at Alyssum Street, Reytan Boulevard and
Morden Lane by The Municipal Infrastructure Group Ltd. as part of the study. The
preliminary design exercise confirmed that the recommended twin 3 m wide x 1.8 m
high concrete box culverts are feasible at all three locations and can be installed within
the existing road right-of ways and City owned channel lands.
The Municipal Infrastructure Group Ltd. is recommended to complete the Detailed
Design of Culverts and Erosion Control for Krosno Creek
In accordance with Purchasing Policy 10.05 where the project or annual cost of a
consulting or professional service assignment is expected to be more than $30,000.00
and the initiating Director intends to acquire the services without obtaining written
proposals, the Director shall submit a Report to Council to obtain approval to engage
the services of a particular consultant.
The Municipal Infrastructure Group Ltd. and it's team of sub-consultants were previously
hired by the City to undertake the Krosno Creek Flood Reduction Study Class EA,
which included preliminary design of the culvert replacements. Staff had an excellent
experience with The Municipal Infrastructure Group Ltd. throughout the Class EA Study,
which was completed within the expected timelines and under budget. The hiring of The
Municipal Infrastructure Group Ltd. and it's team of sub-consultants, represents good
value as they have the necessary project history, specifically with the, new
hydrologic/hydraulic model, to ensure that the detailed design of the culverts has been
done in accordance with the preliminary design and detailed investigations. It is
essential that the design of the erosion control of Krosno Creek be completed at the
same time as the design of the culverts, as the culverts wing wall design and the
overlapping erosion protection for the approaches and transitions between the culverts
is key to a successful and seamless design.

2 PROJECT UNDERSTANDING
The Frenchman's Bay Stormwater Management Master Plan (FBSWMMP), completed in 2009, identified 1
flooding and erosion issues in the Krosno Creek, largely caused by uncontrolled runoff from development
occurring before the emergence of stormwater management technologies. Following the Master Plan, a Class
Environmental Assessment (EA) was completed in February 2015, which analyzed the most effective means
of minimizing'flood risks in the Krosno Creek watershed. It was determined that the limited capacity of three
roadway culverts to convey flows during large rainfall events was contributing significantly to the flood issues in
the study area.
The preliminary design completed as part of the EA recommended that these culverts, located at Morden
Lane, Reytan Boulevard, and Alyssum Street, be replaced with 3.0m x 1.8m twin box culverts.
The FBSWMMP also identified the presence of erosion in the 'natural' portion of the Krosno Creek between
Reytan Boulevard and Sandy Beach Road. The channel has shown signs of planform movement and
downcutting over time,and may threaten private properties through the erosion process in the near future.
The Krosno Creek Detailed Design Project involves the preparation of detailed design drawings, specifications,
and the contract administration for the construction of the three culverts identified in the EA. It also includes the
assessment and restoration of severely eroded sections of the creek that were identified in the FBSWMMP.
3 WORK PLAN
We have thoroughly read the required scope of services identified in the City's Terms of Reference. We
understand the project will encompass the following works:
• Replacing culverts at Morden Lane, Reytan Street, and Alyssum Avenue with twin box culverts;
• Assessing the natural channel portions of the creek(approximately 800m in length);and
• Developing a restoration plan of Krosno Creek,from Reytan Boulevard to Sandy Beach Road.
The following sections summarize and describe the key elements of our work plan to fulfill the terms of
reference for this assignment.
3.1 Data Collection and Review of Existing Conditions
3.1.1 Detailed Topographic Survey
We have reviewed the topographic surveys that were completed as part of the preparation of the
Environmental Assessment These surveys were completed for preliminary design purposes, and were
focused on the culverts and roads.Additional survey is required in order to design the creek restoration portion
of the project, and to provide the specific baseline information required to complete the detailed design.
This survey will provide more detailed elevation information within the channel and floodplain,which is required
to complete the fluvial geomorphic design of the system. We will also survey all inverts of the storm and

sanitary system in close proximity to the culverts to locate these systems in preparation for the construction of
the culverts.
No detailed legal survey information is currently available for the study area. The GIS-based parcel fabric
provided by the City was used as part of the Environmental Assessment, and may not be suitable for the
detailed design.The survey price provided includes a legal survey of the study area.
•
3.1.2 Utility Co-ordination
All utility companies that could potentially have buried and overhead infrastructure in the study area were
contacted as part of the EA.T2UE will finalize the utility consultation and coordination process required for the
project to inform the creation of the detailed design drawing package. They will provide specifications with
respect to protecting and/or relocating utilities if required.
Given that the Scope of the project has expanded since the EA was completed, T2UE will also identify any
utility conflicts that exist within the portion of the creek to be.restored, beyond the area already investigated.
TMIG will consolidate utility information provided by T2UE in the detailed design drawings and tender
documents.
3.1.3 Ecological
The ecology team will perform the required background studies that are needed to provide design
recommendations, comment on constraints related to the ecological system, and oversee the ecological
components of the permitting process with the Toronto Region Conservation Authority (TRCA) and/or the
Department of Fisheries and Oceans (DFO) related to the replacement of the culverts and stream restoration
works.
They will perform the following surveys/assessments required to make recommendations on the timing of
construction, erosion and sediment control,fish rescue,dewatering operations,and culvert and creek designs:
• Terrestrial Vegetation(Spring/Summer 2015)
• Aquatic Habitat(Summer 2015)
• Targeted Barn Swallow(Summer 2015)
3.1.4 Geotechnical Investigation
A geotechnical review of the existing site conditions is required to inform the design of the foundations of the
proposed box culverts and to identify dewatering requirements for the installation of the culverts. We expect
that the borehole information that was collected by SPL through the EA process is suitable in providing these
recommendations, and as such,we have made no provision for additional data collection works.
3.1.5. Fluvial Geomorphology Field Investigation
A Fluvial Geomorphic investigation will be performed to advance previous studies completed by GHD, and
collect data between Reytan Boulevard and Sandy Beach Road. This area has been previously identified for
repairs, and the updated assessment can be used to substantiate the need for channel restoration:
The following works are included:
• The valley or channel corridor will be characterized with respect to the degree of confinement,
dominant vegetation type,woody vegetation density/cover,and surrounding land use; and
• Between Reytan Boulevard and Sandy Beach Road, the cause and extent of bank erosion, as well as
associated hazards to private property and infrastructure, will be investigated to help determine the
appropriate type of restoration and erosion protection required. Moreover, observations of flow
patterns, bank condition (e.g., undercutting, sloughing, etc.), entrenchment, woody debris, in-stream
structures, channel armouring and fish passage barriers will be documented. Measurements of
bankfull channel width and depth, pool and riffle flow depths, bed substrate, bank materials and
vegetation rooting depth will also be recorded.This information will be summarized and included in the
design brief to provide a detailed description of existing conditions.
A survey consisting of channel cross sections and the bed profile will be conducted for Krosno Creek to
determine bankfull channel characteristics. This survey will be completed where the channel is in a relatively /�r�

natural state, likely from Reytan to the backwatered channel resulting from the lake effect.The survey data will
be analyzed with other measured data as well as an estimate of Manning's roughness coefficient to estimate
bankfull flow characteristics such as discharge, average velocity, stream power, bed shear stress, and flow
competency (i.e. sediment entrainment sensitivity). This information will be used to determine suitable bank
restoration/stabilization methods.We note that this analysis is required to provide design rationale.
The field investigation will be provided to the City and will allow City Staff to decide whether declaring an
emergency is required. There are submission requirements associated with declaring an emergency, both to
the Ministry of the Environment and Climate Change (MOECC) and TRCA. The field investigation will include
the necessary time to provide input to the City in completing these applications. The completion of a Schedule.
'B'EA for the creek restoration is included in Section 3.2 as a provisional item.
3.2 Schedule B Municipal Class EA for Restoration Works(Provisional)
As suggested in the Terms of Reference,the work plan may need to be supplemented by the completion of a
Schedule 'B' Class EA if the channel works cannot be performed under emergency works.. It is our
understanding that the emergency works designation would need to be made by the City of Pickering. We
would support this determination with our observations and assessments.
If necessary, we will provide services to fulfill the requirements of the Schedule B Class EA requirements as
set out by the Municipal Engineers Association(2000,as amended 2007 and 2011). The following tasks would
be completed in addition to those described in the above work plan:
• Prepare the Notice of Study Commencement;
• Develop and evaluate alternative solutions, and determine the preferred solution;
• Consult with the public;and
• Prepare the Project File Report and Notice of Study Completion.
Given the relatively small scale of the project and completion of the culvert EA, we have assumed that no
public meetings will be required for this project.While public consultation is required for all EAs, we expect that
the requirements will be fulfilled through the notices of study commencement and completion, and via
information and requests for feedback provided on the City of Pickering's website.
TMIG and GEO Morphix will provide the information that will be presented on the City website and local
newspapers, and expect that the City will coordinate the technical aspects of uploading and presenting the •
information.
3.3 Preliminary and Detailed Design-Culverts
3.3.1 Base Plan Preparation
The topographic survey will be combined with field observations and inventories from the TMIG team to create
relevant base drawings for an accurate and detailed base plan for the culvert replacements and creek
restoration. Information on above- and below-ground utilities from the topographic survey and T2UE
investigations will also be clearly indicated on the base plan.The base drawing will conform to the latest City of
Pickering standards.
We intend to complete the design using AutoCAD Civil 3D and, as such, the topographic survey will be
converted to a digital surface model for our design and quantity calculations. All digital files prepared through •
this assignment, including AutoCAD drawings,will be provided to the City.
3.3.2 Hydraulics
TMIG previously completed a preliminary hydraulic analysis for Krosno Creek as part of the Environmental
Assessment, which was used to size the twin box culverts for the purposes of reducing flood damages based
on a PCSWMM model of Krosno Creek. The PCSWMM modelling did not include some of the conservative
parameterization required by TRCA, but was intended to provide a more realistic risk assessment to inform the
decision making process, and was eventually used to size the culverts at Morden Lane,,Reytan Boulevard, and
Alyssum Avenue.The EA model is sufficient in determining the size of the culverts required, therefore we do
not intend on updating the analysis previously completed.

Detailed Design of Culverts and Erosion Control for Krosno Creek
CITY OF PICKERING I June 11,2015
As part of the permit application,TRCA will require the changes to the culverts to be reflected in their hydraulic
models and floodline maps. We will obtain this information from the TRCA and perform the update of the
hydraulic mapping and modelling, as per TRCA requirements. No additional hydraulic modelling is required as
part of this project.
The hydraulic assessment will be summarized in a detailed report with the fluvial geomorphic assessment, if
the EA Project File Report is not required.
3.3.3 Culvert Replacement Plans ;
The culvert replacement plans for the project will identify the required grading, changes to existing servicing,
culvert length and dimensions, location of wingwalls and headwalls, fill and stone treatments within the
culverts, replacements details for the concrete channel base and side slopes, and utility protection details.We
have assumed that no significant utility relocations are required for this project
A preliminary design was completed as part of the EA, and will be advanced to 30% completion and submitted
to the City and TRCA for review prior to the completion.of the detailed design drawings.
In addition to the design work required to assemble the culvert replacement plans, there is a project
management and coordination role required to compile the design information and specifications from the
various subject matter experts.This would include:
• Drawing culvert foundations and confirming design details with geotechnical engineer,
• Meeting with structural engineer to confirm optimal location/constructability and material requirements
for headwalls and wingwalls, and including structural details and specifications in the culvert
replacement design package;
• Coordination of ecological and fluvial designers and input in creating suitable transitions from the
culvert inlet and outlet into the channel that meets engineering and environmental requirements;
• Identification of disturbance required to construct the project,and coordination with landscape architect
in creating tree removal plans;and
• CADD work required to input detailed utility information into drawing package and identify utility
protection needs on project drawings.
Input from technical specialists will be required to complete the culvert restoration plans as summarized in the
following sections.
3.3.4 Structural
GD Jewell will perform structural engineering duties for the project. TMIG will work closely with the structural
engineer to identify the required locations for these works and will compile structural details and specifications
on the contract drawings and in the tender package(included in Section 3.3.3).
Services for detail design of the culvert replacements shall include, but not be limited to,the following:
• Performing detailed structural design, including:
o Ensuring the design is in accordance with City of Pickering requirements and the Canadian
Highway Bridge Design Code(CHBDC);
o Preparing detailed structural contract drawings in AutoCAD;and
o Ensuring that all drawings be stamped by two professional engineers licensed to practice in
the province of Ontario;
• Completing quantity calculations and preparing a tender item list with quantities for the culvert
replacement work;and
• Preparing special provisions in the Tender Document for the items related to the culvert replacement
work.
All structural design services will be in accordance with the most recent version of the following documents:
• Canadian Highway Bridge Design Code(CHBDC)

Detailed Design of Culverts and Erosion Control for Krosno Creek
CITY OF PICKERING I June 11,2015
• MTO Structural Manual
• MTO Concrete Culvert Design and Detailing Manual
• MTO Culvert Planning Guidelines
• Ontario Provincial Standards
3.3.5 Erosion and Sediment Control/Construction Management/Removals
•TMIG will prepare the required erosion and sediment control plans for the project, which will include details
with respect to the following:
• Bypass and dewatering details and locations
• Creek isolation plans
• Construction Access Details
• Traffic Management Details
• Removals plan
• Environmental control notes and specifications required by TRCA
3.3.6 Tree Removals/Restoration
Tree removals will be required to facilitate the removal of the culverts. SBK will perform the following tasks, in
order to satisfy the City of Pickering and TRCA requirements:
.• Detailed inventory and analysis of existing vegetation within the project study area;
• Tree Preservation Plan including recommendations for tree preservation and removals, as required,to
accommodate the new culverts;.
• Naturalized landscaping around the new culverts, including native trees,shrubs, and seed mixes;and
• Other landscape features,as required,to satisfy the City of Pickering and TRCA.
3.3.7 Geotechnical
The proposed culvert installation will likely require the removal and replacement of portions of the existing
concrete channel at Morden Lane, and at the upstream side of Reytan Boulevard. SPL will provide the design
recommendations and specifications for the removal and replacement of these sections.
As part of the preparation of the EA, SPL completed two boreholes at each culvert crossing, and made
recommendations on the foundations for each of the culverts. SPL will review the design drawings to confirm
that the recommendations in the geotechnical report already prepared are properly incorporated into design
drawings.
3.4 Preliminary and Detailed Design—Creek Restoration
3.4.1 Fluvial Geomorphology
GEO Morphix will lead the design process for the creek restoration project.The field data will be analyzed and
summarized to ensure that natural channel form and function are maximized to the extent possible in the
channel restoration design, and to define the limits of restoration. To ensure that the design provides a long-
term solution, the broader watershed condition such as land use, hydrology, and soilgeology will also be
considered. Opportunities for local enhancements will also be explored to develop a solution that results in a
net increase in fish habitat productive capacity, in consultation with Savanta.At this time,we assume that only
the section of Krosno Creek between Reytan Boulevard and Sandy Beach Road will require restoration. We
will advise the City of Pickering of any additional restoration required following the collection of detailed field
observations.
The proposed design will be shown in plan, defining the limits of work.The design will also include the channel
profile and sufficient number of cross sections to clearly show existing and proposed conditions. The cross
sections will include any overbank (i.e. valley floor and walls) re-grading, and the stabilized banks, while the
•
profile will show grade controls, if required, and any new bed material. Typical details such as bioengineering
and grade controls will also be provided.

CITY OF PICKERING I June 11.2015
3.6 Tender Preparation and Cost Estimates
Upon completion and City approval of the detailed design, we will finalize the Schedule of Items, including
quantities, current industry prices, and total construction cost estimate. Engineering and landscape
specifications will also be provided,allowing the City to tender the project in 2016.
3.7 Construction Administration
In order to estimate a lump sum construction administration and inspection budget, we have assumed the
project will require a three month (14 week)construction period to be completed. During this time,TMIG will be
available for full-time inspections(40 hours/week)and will work closely with the City of Pickering to inspect the
construction works and administer the contract We have assumed that 12 hours/week will be required to
administer the contract.
We have also assumed that during the creek restoration phase of the project, GEO Morphix staff will be
available for periodic site visits (approximately one day per week) to provide input to the contractor on field
fitting that it typically required as part of creek restoration works.We have estimated that the creek restoration
phase will require approximately 6 weeks to complete.
Note that the construction period will depend on the components of the final design, and the contractor chosen
to complete the works.As such,the time periods are estimates only.
It is expected that fish and wildlife rescue may be required to facilitate the construction of these works.We will
include the cost of providing ecological support during construction as an item to be included in the
construction costs, and as such, have assumed that no further ecological support is required during
construction.
We currently have not included a price for geotechnical review of the construction works.When more is known,
this price can be provided. We estimate half-time inspection plus disbursements will be required during the
construction of the culvert foundations.
We also recommend that a pre-construction survey of houses in close proximity to the construction works be
completed in advance of the construction, to collect formal documentation of the existing conditions. Previous
experience in similar works has shown that the small cost of these surveys can save significant costs
associated with potential litigation. We would expect that the pre-construction survey costs will be included as
a requirement of the construction works, and have not included costs for these works in this proposal.
4 PROJECT MANAGEMENT MEETINGS
4.1 City Technical Working Group(TWG)
We have assumed that TMIG staff will be available to attend four (4) Technical Working Group (TWG)
meetings. We intend to bring select specialists from the subconsultant team to these meetings, based on the
subject matter. We have assumed that staff from GEO Morphix will attend two (2) meetings, and SBK and
Savanta will attend(1)TWG meeting each.
TMIG staff will be in close contact with other subconsultant teams, and will provide representation on behalf of
these members at the Technical Working Group.We will provide minutes of the TWG meetings and distribute
to the study team.
We have assumed that TMIG staff only will attend additional meetings with the Technical Working Group.The
cost for additional meetings is $1500, including travel costs, and assumes a half day for two senior staff to
attend the meeting at the City of Pickering and provide minutes.
4.2 Project Management/Schedule
We have allocated time to project management for the purposes of coordinating the subconsultant and design
teams,communications with the City of Pickering's Project Manager, and the TWG meetings.
Minutes will be issued within three business days of each meeting, and any issues potentially affecting the
project budget and schedule or the construction budget and schedule will be brought to the City's attention as
soon as they are discovered.

CITY OF PICKERING I June 11,2015
Given the anticipated start date of late July/early August, we have assumed that terrestrial vegetation surveys
will be completed in Summer and Fall of 2015.We expect that this will be acceptable to TRCA, but understand
that they have requested that a spring survey is required in the past (as opposed to the fall survey). If this
occurs, it would impact the schedule for completion of the project.
A detailed time-task matrix is included in Appendix A. Assuming that the Purchase Order will be before the
end of July,we anticipate the following milestones to be achieved:
Completion of Field Investigations September 4,2015
30%Design Submission November 6,2015
90%Design Submission January 29,2015
Schedule of Items, Specifications and Cost Estimate February 26,2016
