Walton Development and Management
The Walton Group of Companies is a multinational real estate investment and development firm concentrating on the research, acquisition, administration, planning and development of strategically located land in major North American growth corridors. With nearly 90,000 acres of land under administration including 22 development projects, Walton is one of North America’s premier land asset managers.
Walton Development and Management L.P. (“Walton”) has retained Greenland International Consulting Ltd. (“Greenland”) to assist with our municipal infrastructure planning and engineering design for several new communities in the County of Simcoe, Ontario including environmental assessments and water resource analysis. Greenland is highly regarded in the industry for their professional approach to the environmental aspects of these projects and state-of-the-art decision support tools (such as CANWETTM) to address climate change adaptation, cumulative watershed impact, and adaptive management such as post-construction performance monitoring. Greenland’s business model is unique and has provided Walton with value-added deliverables through the use of best available science and solution-based methodology. This includes forming a landmark public/private sector phosphorous reduction program to protect a sensitive fishery habitat system within headwaters of the Nottawasaga River Basin for one of Walton’s projects in Simcoe County. Greenland’s CANWETTM model and other in-house stormwater management and climate change impact assessment tools were instrumental for Walton to establish long-term partnerships in this community, including the local municipality, Nottawasaga Valley Conservation Authority and other key stakeholders.

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.
