Basement Flooding Remediation and Water Quality Improvement Master Plan - Area 36

City of Toronto


Client: City of Toronto

Project Duration: September 2015 – Ongoing

Detailed examination of the existing sanitary and storm drainage systems within the City of Toronto’s “Area 36” which is located in Etobicoke (vicinity of Kipling Avenue, Islington Avenue, Royal York Road, south and north of Highway 401), with storm drainage outlet being Humber Creek, a tributary to the Humber River. The project included extensive field work and ground truthing to confirm surface drainage connectivity within residential neighbourhoods and the commercial/industrial area north of Highway 401, and to help identify overland flow pathways. Once the field work was done, a detailed hydrologic/hydraulics model was developed using the Innovyze Infoworks CS modelling platform. Model calibration and validation were undertaken using flow data available from a number of sewer flow meters, and the model was used to simulate system response to historical events (such as the large rain event of July 8, 2013) that resulted in reports of basement and surface flooding.

Once the model had been validated, it was used to develop a number of remedial alternatives for flood-prone “cluster areas” within the overall project area. The alternatives under consideration were presented at the first of two public information sessions; and the preferred approach to meeting the City’s level-of-service requirements was presented at the second public information session.

Conceptual designs were prepared for the preferred alternatives looking at all aspects of constructability and permitting needs.

The project is currently being finalized by COLE to determine what the implementation priorities should be, based on considering the benefit/cost ratio of individual component projects.

This project was completed following the Class Environmental Assessment process.

Rebecca Sanitary Trunk Sewer

Halton Region


Client: The Regional Municipality of Halton

COLE was retained by the Regional Municipality of Halton for the detailed design, contract administration and inspection of 4.2km long microtunnel project comprised of 2.5km 1200mm ID and 1.7km 1350mm ID pipe construction. The Rebecca Trunk Wastewater Main project includes a total of 14 microtunnel drives (12 rock drives & 2 mixed face drives) varying in length from 160 meters to 395 meters. Twelve of the drives are curved or composite curves in part based upon requirements to limit impacts to existing utilities, protected trees and existing structures; minimize easement requirements, maximize clearance beneath environmentally sensitive creeks, and connection locations required to remove existing pumping stations offline.

The rock drives are located within the Queenston Formation and Georgian Bay Formation, which comprise Shales with interbedded Siltstone and Limestone (hard layers). The mixed face drives comprised of Georgian Bay Formation and Glacial Till. All drives are below the water table.

Design considerations included provisions for swelling Shale, interbedded hard layers (Limestone & Siltstone) within the softer Shale, high horizontal stress, areas of limited ground cover (less than 0.4 MTBM diameters), curved and composite curved alignments (minimum radius of 430 meters), and pipe requirements including provision for grout ports and gaskets / watertightness.

Upper Unionville Development

TACC Developments


Client: TACC Developments

Completion Date: On-going

COLE was engaged to provide the preliminary/detailed design, approvals, construction administration and final assumption for the Upper Unionville site. Located in the northeast quadrant of 16th Avenue and Kennedy Road, the 205 acre site consists of 1700 residential units, three elementary schools, two stormwater management ponds and various public parks. Timing of development build-out was accelerated due to the early allotment of “servicing allocation” from the City of Markham, a direct result of the successful Inflow and Infiltration Reduction program instituted by COLE.

The pilot program was the first of its kind in York Region to seek out and reduce stormwater flow into existing sanitary sewers and in exchange, advancing the overall schedule for home building by several years. As a result, the design for the Upper Unionville residential development incorporated current environmental and sustainability guidelines. In particular, low impact development (LID) measures were used in conjunction with traditional stormwater management techniques, aimed at replicating pre-development groundwater discharge rates to maintain the water balance under post-development conditions. Additionally, a Travel Demand Management Plan was completed, which described the network of cycling routes and pedestrian walkways within the development and their connectivity to existing trails on a community-wide scale. The Plan also included future York Region Transit routes to illustrate the convenience of access to shopping and educational or employment centres.

Ponytrail Dr & Rathburn Rd E Sanitary Sewer and Watermain

Regional Municipality of Peel


Client: Regional Municipality of Peel

Completion Date: 2019

As part of the Region’s State of Good Repair Program, and mitigation of basement flooding issues in the area, the Region of Peel required new watermains and sanitary sewer main in the City of Mississauga. Then main construction methods were Microtunneling / Jack & Bore (17.3%) and Open Cut (82.4%). Some project challenges included utilizing open cut and trenchless construction methods within narrow, congested residential streets; and the installation of a sewer microtunnel in close proximity to a large existing storm sewer. The main services include:

  • Topographical Survey
  • Base-map Preparation
  • Preliminary Design
  • Detailed Design
  • Tender Document Preparation
  • Contract Administration and Inspection
  • Hydrogeological Report

Vaughan Healthcare Centre

City of Vaughan


Client: City of Vaughan

Completion Date: Ongoing

COLE was retained by the City of Vaughan to provide engineering services in connection with the development of the 33-hectare Vaughan Healthcare Centre precinct plan at the northwest corner of Jane Street and Major Mackenzie. The plan will guide the development of the site for health care uses. COLE prepared a Functional Transportation Master Plan, a Master Servicing Plan, a class EA and a Phase 1 ESA, followed by detailed design drawings for construction of the internal needs and services; two stormwater management ponds, a temporary sewage pumping station and new signalized intersections on Jane Street and Major Mackenzie.

The proposed Mackenzie Vaughan Hospital occupies approximately 16-hectares of the site.

Peter Matthews Drive Road Construction and Taunton Road Widening

North Pickering Community Management / Region of Durham


Client: North Pickering Community Management / Region of Durham

Competion: 2019

COLE was retained to complete pre-design, detailed design, tender preparation, contract administration and site inspection services for the design of 600m of new Regional Arterial Road (Peter Matthews Drive) and the widening and construction of new intersections, pedestrian crosswalks, transit stops and multi-use paths along a 1 km segment of Taunton Road, in the City of Pickering.

Peter Matthews Drive included two signalized intersections, landscaped boulevards, streetlights, multi-use paths and sidewalks that needed to be coordinated with the adjacent subdivision design.

Taunton Road was partially rehabilitated with a new profile to accommodate the new Peter Matthews Drive Intersection. It was also updated with more urban-like features and speed reduction measures along the corridor to suit the new developments and the expected increase in pedestrian and cyclist activity.

Consultancy Services to Develop a Strategic Framework for Water Resources Management

Nevis Island Administration


Client: Nevis Island Administration

Duration: 2015 – 2016

COLE reviewed the existing Integrated Water Resource Management (IWRM) policies and legislation in Nevis and other Caribbean Nations, and developed a draft IWRM Strategies and Implementation Plan, supported by draft policy and legislation and proposed institutional restructuring. Cole Engineering facilitated two all-day, on-site stakeholder workshops, followed by individual meetings with key government officials, to discuss results and recommendations and obtain feedback for incorporation into subsequent reports. Initial findings were presented at the CWWA Conference in August 2015. The work involved in this project provided excellent international exposure to Cole Engineering’s Team of Environmental Specialists and Hydrogeologists.

The main challenge was adapting our experience in the water sector, our design and our recommendations to a territory with a small population of 13,000. A further challenge existed because of the lack of data collection and management systems for sustainable water resource management. However, one of our recommendations that the Nevis Island Administration will consider is implementing hydrogeological monitoring for a period of time to collect sufficient data from which further recommendations can be made.

The project schedule was successfully met and within cost budget, with the final report submitted to the client in June 2016. Cole Engineering received excellent ratings from the Nevis Island Administration (NIA) in meeting the client’s expectations, managing costs, maintaining the project schedule, working with the client’s team, and overall assessment, and were informed by NIA of a 90% likelihood that they would hire us again and recommend us.

Our project team brought our extensive experience in the water sector to a Small Island Developing State (SIDS). This programme will move Nevis to the forefront of responsible water governance and can serve as an example to other SIDS.
