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.

Town of Collingwood

RE: Town of Collingwood ‘Smart’ Stormwater Project
 
I would like to thank and recognize GREENLAND® for their leadership role in the above project. Your firm identified the opportunity to work together with other private firms and public sector organizations, together with the support of the Town of Collingwood and the Federation of Canadian Municipalities, to address a growing Concern in communities related to lot-level flood mitigation.
 
GREENLAND® strategized and implemented, over almost 3 years, the “first-ever in Canada” work plan to mitigate problems of climate-change induced stormwater flooding which impacts many residential, commercial and institutional properties. The innovative project approach monitored 4 different Low Impact Development (LID) approaches for reducing lot-level flooding and their ability to redirect site drainage away from municipal sewer systems. Using innovative real-time (aka ‘Smart’) technologies, GREENLAND® was also able to generate ‘Big Data’ that provided new insights into the effectiveness of these different approaches. The GREENLAND® team’s level of commitment, thoroughness and professionalism was appreciated by the municipality. GREENLAND® maintained open lines of communication with Town staff, contractors, participating residents, and promptly responded to all questions and issues raised by the public.
 
We commend your firm’s efforts as a pioneer in implementing this project approach.

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.
