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.

Corporation of the Town of Collingwood (Canada)
On behalf of Council and the residents of Collingwood, I want to thank you for generously giving your time, expertise and experience to our community to assist Town staff in addressing the water capacity issues at the Raymond A. Barker Water Treatment Plant (WTP).
Since becoming aware of the capacity issues this spring and then implementing an Interim Control By-Law, this issue has been the top priority of Council. Your input and contribution on proactive measures to mitigate the summer/winter capacity differential and to increase the WTP capacity pending the completion of the expansion have been of great benefit to Council and to staff. As a result of your input, Council directed staff to include the option of UV Disinfection retrofit to the existing WTP as part of the expansion design RFP process and we are optimistic this will be done.
Thank you for your personal and professional commitment to our community, it is impactful and very much appreciated by myself and my Council colleagues.
Yours very truly,
Brian Saunderson
