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.

Client Testimonials

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.

Town of Collingwood

On behalf of the Town of Collingwood, I would like to thank the Greenland Group of Companies for their design and execution of the Town’s vision for Heritage Park, coordination of all consultants, contract administration and construction inspection.

Greenland always strives for thoroughness, professionalism and addressing their clients needs on each of their projects – this was no exception.

Agriculture and Agri-Food Canada

In March of 2013, Greenland International Consulting Ltd. completed a study for Agriculture and Agri-Food Canada to estimate nutrient loading in small catchment of about 177 square kilometers in the La Salle River watershed in southern Manitoba using the CANWET 4 model. Given uncertainties in some input data and model parameters, the preliminary results using the CANWET 4 model for baseline conditions of stream discharge, nutrient concentrations and loads were satisfactory in our project team as simulated values were within the range of observed values during the validation period.

This study suggests the CANWET 4 modeling approach could be used to predict changes to nutrient loads from changing land use scenarios in watersheds of this region.
