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 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.

City of Ottawa

On behalf of the City of Ottawa, we would like to thank Greenland International Consulting Limited, and in particular, Don Moss for his exemplary efforts in his role as Model Keeper for the City of Ottawa… Greenland has achieved a high level of confidence with Senior Staff and City Council as well Conservation authority and the Ontario Ministry of Environment… The City is appreciative of the new Modelling Tool developed by Greenland which will assist the City in conducting timely and efficient development reviews. The City will now be able to test proposed infrastructure with the overall development, determine changing impacts to existing infrastructure as ponds, as well as any changes to the receiving watercourses.

Don’s knowledge, dedication and professional approach over the past five years has been a crucial factor in the success of the project under very challenging circumstances.
