Low Impact Development (LID)

Low Impact Development (LID) is a stormwater management and land development strategy applied at the road right-of-way, site plan and subdivision scale. This strategy emphasizes conservation and use of on-site natural features, integrated with engineered, small-scale hydrologic controls to more closely mimic pre-development hydrology. The goal of LID is to prevent measurable harm to streams, lakes, wetlands and other natural aquatic systems from commercial, residential or industrial sites. LID technologies and related design practices are used by GREENLAND® clients (wherever feasible from a functional perspective) for municipal infrastructure and land development projects.

Our LID planning and design strategy (by our engineering and landscape architecture teams) can include:

  • Green roofs;
  • Rainwater gardens;
  • Rainwater harvesting systems;
  • Permeable pavement structures
  • Bio-swales;
  • Artificial floating islands; and,
  • Other innovative ‘smart systems’ developed from the principles of bio-mimicry.

Six Nations Council

On behalf of the Environment Office of the Six Nations of the Grand River, we would like to thank Greenland International Consulting Limited for the work completed to prepare the Master Drainage and Flood Remediation Plan (MDFRP) for the McKenzie Creek watershed. This plan has now enabled our office to identify the flood prone residences throughout the watershed with the flood plain mapping that has been prepared as part of this assignement. We appreciate the role that Greenland has played in assisting our office in directing Public Works with prioritizing the remedial projects to be completed in the flood prone areas. 

We also appreciate Greenland's effort in assisting the Six Nations of the Grand River with the preparation of funding applications to secure the resources to complete these remedial works. We are convinced that this MDFRP can be used as a template for completing similar drainage and flood remediation works both locally and in other First Nations lands. 

We look forward to working with your company again in the near future on the remaining watersheds that need this important work done. 

Thank you for your ongoing assistance.

Muskoka Watershed Council

The Muskoka Watershed Council’s mission is to champion watershed health in those watersheds that flow into and through the District Municipality of Muskoka. There is no conservation authority in Muskoka, instead the Council is a volunteer-based organization supported by the District of Muskoka, local consulting firms, and local Ministry of Natural Resources and Forestry and Ministry of the Environment and Climate Change offices.

The Muskoka Watershed Council is currently undertaking a project to understand the potential impact of climate change in Muskoka to the year 2050. In working with our municipal partners, decision support tools such as Greenland’s new CANWET-5 model could be useful in informing our watershed management planning decisions in relation to policy development, stewardship priorities and education and communication programs.

Lake Simcoe Region Conservation Authority

RE: Town of Innisfil (Community of Alcona) Flood Reduction Class Environmental Assessment

On behalf of the Lake Simcoe Region Conservation Authority (LSRCA), I would like to thank GREENLAND® International - Consulting Engineers for the excellent work undertaken to complete the Flood Reduction Class Environmental Assessment for the Community of Alcona. I also want to provide you our sincere appreciation for the support GREENLAND® provided both in-kind and financially which allowed the project to proceed. The approved strategy will now enable the LSRCA and Town of Innisfil to move forward with the next phase of the project so that the science-based, publicly supported solution, can be implemented to alleviate flooding impacting residents in Alcona as soon as possible. 

The project goal was to develop a sustainable - engineering solution to reduce significant annual flood damages currently occurring within the Community of Alcona (Town of Innisfil) and located within the Belle Aire Creek subwatershed. The project included a Class Environmental Assessment (EA) process with extensive public and other stakeholder consultations to advance a solution involving enhancing a wetland (green infrastructure) to provide flood mitigation. The project was proposed over a decade ago and was then adopted in the Town’s Master Drainage Plan as required under the Lake Simcoe Protection Plan. It is now one step closer to completion. 

The project deliverables produced by GREENLAND® included an Environmental Study Report (ESR) which now provides a science-based, well-engineered, thorough and systematic understanding of the chronic flooding that has impacted the affected settlement area in the Town of Innisfil. The Environmental Study Report (by GREENLAND®) also developed a proactive flood mitigation and resiliency plan that can now be implemented by the LSRCA, Town and other stakeholders. Finally, the project work plan satisfied requirements of Ontario's Class Environmental Assessment process and with an effective/collaborative spirit of a "public-private partnership” utilizing and ecosystem approach. The timelines to complete the project were very aggressive and I was pleased that GREENLAND® was able to complete the project on-time and budget. 

In conclusion, the role that GREENLAND® played to prepare the funding application for Canada’s National Disaster Mitigation Program; securing in-kind participation of the Intact Centre on Climate Adaptation (ICCA) at the University of Waterloo; providing in-kind Intellectual Property leveraging resources, and the financial contribution helped ensure the project was a complete success. I look forward to working with your company again on other partnerships of mutual interest and would be pleased to serve as professional references on similar projects.
