as outlined in the Road Servicing Agreement as follows:
a)the sum of $163,757.00 to be funded from the City’s DC Share Reserve;
b)the sum of $491,272.00 to be funded from the Development Charges Transportation
Reserve Fund; and,
4.That the appropriate City of Pickering officials be authorized to take the necessary
actions as indicated in this report.
Executive Summary: The City of Pickering retained AECOM Canada Ltd. in 2017 to
undertake the Municipal Class Environmental Assessment (Class EA) study to extend Walnut
Lane from Kingston Road to Liverpool Road. The extension is required to service existing,
approved, and proposed development in the City Centre and Liverpool neighbourhoods
including the proposed development by Tribute (Liverpool) Limited on the west side of
Liverpool Road, north of Highway 401.
The Class EA study was presented to Council through Report ENG 19-22 at the June 27, 2022
Council meeting. At this meeting through Resolution #946/22, Council endorsed in principle the
Draft Environmental Study Report associated with the Class EA study. The Environmental
Study Report is being finalized and will be filed for the 30 day public review period, and a
Notice of Completion will be issued.
Tribute (Liverpool) Limited requires the Walnut Lane extension to be constructed to provide
access to their development. In order to advance the construction of the road, Tribute
ENG 21-2022 September 20, 2022
Subject: Road Servicing Agreement with Tribute (Liverpool) Limited
Walnut Lane Extension – Design Component Page 2
(Liverpool) Limited has requested to take on the responsibility to undertake the design and
approvals required for the project, and fulfill commitments made through the Class EA process
related to the design. The estimated cost of design and approvals, in the amount of
$643,700.00 (HST extra), was approved in the City’s 2022 Capital Budget and these funds will
be made available to Tribute (Liverpool) Limited through the Road Servicing Agreement. All
design work will be completed to the City’s satisfaction as the Walnut Lane Extension will
become a municipal road upon completion.
City staff are recommending that a Road Servicing Agreement with Tribute (Liverpool) Limited
be executed to cover all requirements by the City for design and approvals. The Road
Servicing Agreement will include an upset limit of $643,700.00 plus HST for the design, as
approved in the 2022 Capital Budget – Development Projects (DC Funded) account. The Road
Servicing Agreement does not include construction as the current estimated construction cost
provided by the City’s Class EA consultant significantly exceeds the amount approved in the
2022 Capital Budget for this component. In order to undertake construction, there will be a
requirement to have additional funds approved in the 2023 Capital Budget, and a Road
Servicing Agreement with Tribute (Liverpool) Limited for construction will need to be
negotiated. Both of these requirements will require future Council approval.
Financial Implications: The cost to prepare the Municipal Class Environmental
Assessment was approved in the 2017 and 2018 Capital Budgets in the total amount of
$461,226.00. AECOM Canada Ltd. was retained by the City of Pickering through Request for
Proposal RFP-13-2016 and Report ENG 03-17 (Resolution #294/17) to complete this work.
In the 2022 Capital Budget – Development Projects (DC Funded) account, an amount of
$6,550,300.00 (net of HST rebate) was approved for the completion of design, approvals,
permits and construction of the Walnut Lane extension. The amount included $655,029.00 (net
of HST rebate) for consulting soft costs, and $5,895,271.00 (net of HST rebate) for
construction costs based on the cost estimate at the time. The most current estimated cost
provided by the consultant for the design, construction and inspection/contract administration
for the Walnut Lane extension is now $7.7 million due to current market conditions and the
requirement for a larger span structure over Pine Creek. The 2022 Development Charges
Study as approved by Council at the June 27, 2022 Council meeting reflects the current
estimated cost of $7.7 million. As the approved 2022 Capital Budget does not reflect the
current cost estimate for construction, only the design and approvals components are being
captured in the Road Servicing Agreement.
The Road Servicing Agreement will cap the design and approvals cost contribution by the City
of Pickering at $643,700.00 plus HST.

Discussion: Tribute (Liverpool) Limited has approached City staff requesting permission to
undertake the detailed design and acquire approvals and permits for the construction of the
Walnut Lane extension in conjunction with their development approvals for rezoning and site
plan approval of their lands. Tribute (Liverpool) Limited are actively pursuing approvals through
Zoning By-Law application A08/21 and Site Plan application S01/22 for a residential high rise
development consisting of three towers on the west side of Liverpool Road, north of Highway
401.The development requires the Walnut Lane extension to be constructed in order to
provide access.
The design of the Walnut Lane extension between Kingston Road and Liverpool Road is to
conform to the approved Municipal Class Environmental Assessment (Class EA) prepared by
AECOM Canada Ltd. on behalf of the City of Pickering. The Environmental Study Report
(ESR), prepared by AECOM to support the Class EA, was completed in June 2022 and
endorsed in principle by Pickering Council at the June 27, 2022 Council meeting through
Report ENG 19-22 (Resolution #946/22). AECOM Canada Ltd. is in the process of
documenting and inputting comments received by agencies and stakeholders, as well as
responses to those comments, prior to issuing the Notice of Completion and filing the ESR.
Tribute (Liverpool) Limited is currently soliciting a cost estimate from a reputable design
consulting firm that has experience in this scope of work. By entering into a Road Servicing
Agreement with the City of Pickering, Tribute (Liverpool) Limited will be able to complete
negotiations on the design assignment, and commit to commence the design work. City staff
are recommending that a Road Servicing Agreement with Tribute (Liverpool) Limited be
executed to cover all requirements by the City for design and approvals. The Road Servicing

10.3.2 Toronto and Region Conservation Authority Commitments
Through consultation with TRCA for this Project, the following commitments specific to
TRCA, some of which are also identified in Table 10-1, are summarized below to assist
with TRCA’s involvement in the detailed design phase of the Project:
Circulate the detailed design work program (prepared by Tribute Communities
consultant team) prior to the detailed design stage of the project for TRCA’s
review and comment prior to initiation of detailed design.
Set up a pre-consultation meeting with TRCA staff at the detailed design
stage to assist in the submission of a complete application for the permit
application under O.Reg. 166/06. Consultation with TRCA will also be
required to confirm restoration plan details.
Prepare and submit the permit application under O.Reg. 166/06.
Develop a mitigation and restoration plan in consultation with the City of
Pickering and TRCA. Restoration and compensation efforts for the Walnut
Lane extension will be co-ordinated with the Tribute Communities Lands site
works to ensure that there is no overlap.
Prepare and implement an Erosion and Sediment Control Plan prior to
construction activities.
Directly involve a fluvial geomorphologist in the detailed design of the new
proposed crossing in order to specifically address the observed
geomorphological issues along Pine Creek, namely re-meandering of the
creek.
Review the channel rehabilitation opportunities associated with the proposed
crossing location at Pine Creek, as well as at the existing bank failure located
near the Loblaws parking lot. Further refine restoration options with the
updated HEC-RAS model completed as part of the detailed design work.
If the Pine Creek crossing does not span the meander belt width (36 metre
crossing span, as a minimum), additional erosion protection will be required to
protect the crossing. As a result, some toe protection and channel works will
be needed in the proximity of the bridge abutments against the future fluvial
hazards. These protective measures would need to be reflected in updated
drawings. measures need to be designed by fluvial geomorphologist, and the
drawings need to be reviewed and approved by fluvial geomorphologist
regarding those protective measures. At the time of this publication, the
recommended span width is 36 metres.

retaining systems will need to be reviewed and signed-off by geotechnical
engineer to ensure the global stability.
Make the mitigation recommendations in the EIS into action items and
included in the design and drawings in the detailed design submissions.
If removal within suitable bat Species at Risk roosting habitat cannot be
avoided, additional species-specific surveys such as leaf-off cavity tree
searches, leaf-on surveys and acoustic monitoring following the Survey
Protocol for Species at Risk Bats within Treed Habitats: Little Brown Myotis,
Northern Myotis & Tri-colored Bat to confirm suitable habitat and/or presence
of bat SAR, as well as, authorization from MECP under the ESA will be
required prior to construction.
Provide TRCA with engineering drawings showing all necessary details and
specifications as per the studies and design recommendations.
The following ESR sections and appendices will be used by TRCA to support their
detailed design review:
Section 1.2 – Study Area, Figure 1-1
Section 4.3 – Natural Environment, Figure 4-1a-b Natural Environment Field
