6.That the appropriate City of Pickering officials be authorized to take the actionsnecessary to implement the recommendations in this report.
Executive Summary: The purpose of this report is to obtain Council approval to retain the services of the Toronto and Region Conservation Authority (TRCA) to prepare the detailed design for the Shoreline Improvements from West Shore Boulevard to Marksbury Road.
In April 2024, the City retained the TRCA to perform a Shoreline Coastal Assessment Study
through this area as part of an initiative to establish green space at the top of the bank for parkland development and the construction of the Waterfront Trail through this area. The study was completed in June 2025. Various shoreline protection options were presented, along with their advantages, disadvantages and order of magnitude costs. Staff have determined what
the preferred option for coastal protection measures is and would like to proceed with the
detailed design, in preparation for construction.
TRCA have prepared a letter agreement, outlining the proposed scope of work, timeline, and projected costs to complete the detailed design phase of this project. Once the detailed design is completed, TRCA will submit a separate fee proposal for the implementation of the shoreline
protection measures for review and consideration.
In accordance with Section 19 and Appendix 1, Item 8, of Purchasing Policy PUR 010, the work or services to or from other government agencies, utilities, provincial or federal agencies, crown corporations, municipalities, public agencies or boards are considered an Exception and are excluded from the requirements of the Purchasing Policy. Exception procurements may be
procured by obtaining one price, subject to the funds being available in the Current or Capital
Budgets.
Directors are required to provide details to the Treasurer and the CAO of any contractual arrangements under Appendix 1 with third parties that exceed $25,000 annually or are for more than one year. Such details will be provided prior to the commencement of the contract
arrangement.
Staff are recommending Council approval of the fee proposal submitted by the Toronto and Region Conservation Authority to prepare the detailed design for the Shoreline Improvements from West Shore Boulevard to Marksbury Road, in the amount of $150,096.00 (net HST) or $166,675.00 (HST included) and a total net project cost, including a 10% contingency, in the
amount of $165,106.00 (Net HST).
Relationship to the Pickering Strategic Plan: The recommendations in this report respond
to the Pickering Strategic Plan Priority of Advance Innovation & Responsible Planning to
Support a Connected, Well-Serviced Community; and Lead & Advocate for Environmental Stewardship, Innovation and Resiliency.

The total budget of $2,092,200.00 includes the design, approvals and construction of shoreline improvements and the section of the Waterfront Trail with other parkland development amenities, of which $70,595.88 has been expended to date, leaving a balance of $2,021,605.00. The amount of $1,856,499.00 that remains available in account C10572.2404
will be required for the construction component of the project which is expected to commence
in the Fall of 2026.
Discussion: The purpose of this report is to obtain Council approval to retain the services of the Toronto and Region Conservation Authority (TRCA) to prepare the detailed design for the shoreline improvements from West Shore Boulevard to Marksbury Road.
In April 2024, the City retained the TRCA to perform a Shoreline Coastal Assessment Study
through this area as part of an initiative to establish green space at the stable top of the bank
ENG 16-25 August 12, 2025

for parkland development and the construction of the Waterfront Trail through this area. The project assessed the near-shore coastal conditions, determined the 100-year erosion risk line
assuming no shoreline protection and developed high-level concepts for shoreline protection
that would reduce the rate of erosion and move the 100-year erosion risk line closer to the existing top of bank.
The Shoreline Coastal Assessment Study determined that if no shoreline protection measures were taken, at the existing conditions erosion rate, the top of bank would erode back
approximately 50m in 100 years. Several options were presented that would completely stop
shoreline erosion for the life of the installed infrastructure; these include armourstone revetment work and cobble beach with groynes. These options would require a Class Environmental Assessment and would be very costly. The other options presented, that would not require a Class Environmental Assessment and that could be installed at a lower cost,
involve the use of natural boulders that would be placed along the shoreline, both above and
below the waterline. Based on the volume of stone installed, the erosion rate would be reduced to between 3 metres and 6 metres over the 50 year period. Staff have determined that the natural rock option that would limit erosion to approximately 3 metres over the 50 year period to be the preferred solution.
TRCA have provided a fee proposal for the preparation of the detailed design for the selected
option. Their scope of work includes the collection of background data (such as a topographic survey, archeology assessment, tree inventory, and geotechnical study), collaboration with City staff and external agencies, the development of detailed design drawings and a design report, preparation of detailed cost estimates, and securing the required permits and approvals
in preparation for the implementation of the shoreline protection work.
