Town of Innisfil
Re: Erosion Control and Advanced Sedimentation Pilot Project
On behalf of the Town of Innisfil, I would like to extend my sincere thanks to Greenland International Consulting Ltd. for their excellent work in completing the Erosion Control and Advanced Sedimentation Pilot Project for the Town of Innisfil, funded in part by the Federation of Canadian Municipalities. This project is a first step in broad-scale implementation of innovative stormwater management technologies in the Lake Simcoe Watershed to address on-going phosphorus and sediment concerns within the Lake.
Over the course of the three-year pilot project, Greenland studied the effectiveness of the Clearflow Group’s Advanced Sedimentation Technologies at an active development site in Innisfil. The project analyzed the performance of Clearflow’s Gel Flocculant Blocks and Treated Geo-Jute at removing fine sediments and nutrients at three stormwater management facilities that discharge to Lake Simcoe. These particles, and the associated nutrients and heavy metals, are traditionally not being removed by conventional stormwater management facilities and cause negative impacts downstream. The results of the project will help Innisfil and other municipalities and agencies to reduce sediment load from entering the environment as a result of construction activities.
As the lead consultant, Greenland coordinated with the Town staff, contractors, sub-consultants and the developer to ensure that open lines of communication were maintained and questions and issues raised were responded to promptly. The Greenland Team’s level of professionalism and thoroughness over the course of the project was valued by the Town.

Blue Mountain Watershed Trust Foundation
RE: Huntingwood Trail East OLT – Expert Witness Support
On behalf of the Blue Mountain Watershed Trust Foundation (aka ‘Trust’), I would like to extend the Board of Directors’ sincere gratitude to GREENLAND® for its exemplary technical support on the recent Ontario Land Tribunal (OLT) case.
GREENLAND® was retained to develop a defendable, 2-dimensional hydraulic model of the Silver Creek system with many accompanying spills, and in the vicinity of the proposed development. Your firm’s expertise and proficiency with 2-D hydraulic modelling - floodplain management projects were also instrumental in achieving an amicable solution with the developer’s engineering team lead. The solution will now protect residents and property from increased flooding impacts associated with the original subdivision plan (and for only this development phase).
This included your impeccable team to always maintain prompt communication between the OLT parties, and providing staff expertise and support for a concurrent public engagement by the Trust. Your team’s attention to detail and cross-functional collaboration approach was also key to identifying an amicable solution by all parties of the OLT, and as part of an OLT Settlement.
Mark, it was a pleasure to work with GREENLAND® on this file. Thank you also to your team.

Town of Collingwood
RE: Town of Collingwood ‘Smart’ Stormwater Project
I would like to thank and recognize GREENLAND® for their leadership role in the above project. Your firm identified the opportunity to work together with other private firms and public sector organizations, together with the support of the Town of Collingwood and the Federation of Canadian Municipalities, to address a growing Concern in communities related to lot-level flood mitigation.
GREENLAND® strategized and implemented, over almost 3 years, the “first-ever in Canada” work plan to mitigate problems of climate-change induced stormwater flooding which impacts many residential, commercial and institutional properties. The innovative project approach monitored 4 different Low Impact Development (LID) approaches for reducing lot-level flooding and their ability to redirect site drainage away from municipal sewer systems. Using innovative real-time (aka ‘Smart’) technologies, GREENLAND® was also able to generate ‘Big Data’ that provided new insights into the effectiveness of these different approaches. The GREENLAND® team’s level of commitment, thoroughness and professionalism was appreciated by the municipality. GREENLAND® maintained open lines of communication with Town staff, contractors, participating residents, and promptly responded to all questions and issues raised by the public.
We commend your firm’s efforts as a pioneer in implementing this project approach.
