Our Work

EOR Goes North! Celebrating our New Canadian Office
and Showcasing Canadian Projects

EOR's Olivia Sparrow, P.Eng. has returned home to Toronto and is leading the new EOR Canada Office.

EOR has been working on Canadian projects for 8 years, stretching from Ontario to Alberta. Our projects have addressed developing high-density urban centers, expansive rural/agricultural regions, and smaller, remote northern communities.

The projects involve resource management planning, water quality improvements, stormwater modeling, stream restorations, and low impact development (LID) guides to name a few. See a sampling of EOR's Canadian Projects highlighted below.  

CVC's Designer's Guide for LID Construction Cover

Designer's Guide for LID Construction

  • Completed for the Credit Valley Conservation Authority
  • Extensive manual outlining the design and implementation of stormwater best management practices (BMPs) for low impact development (LID) construction.
  • An indispensable guide for contractors and stormwater management professionals that highlights to Do's and Don't of LID design and BMP implementation.
  • 2012 Award Winner for Visual Communication and Design
Edmonton LID Location Study Cover

Low Impact Development (LID) Location Study

  • Completed for the City of Edmonton and EPCOR
  • The feasible locations, costs, and benefits of urban LID retrofits were identified using optimized geospatial routines in built-out areas of Edmonton.
  • The goal was to quantify if LID could meet the City’s targets for zero increase in pollutant loading as the urban area continues to grow in the future.
  • Retrofits were evaluated based on sustainable-net present value using Autocase, the City’s Triple Bottom Line criteria, and the expected runoff volume and pollutant reductions.
  • A modeling exercise was conducted using PCSWMM to assess the potential reduction in combined sewer overflow (CSO) achieved by LID implementation in a single neighborhood.
  • Overall, the study identified over 85,000 LID retrofit opportunities which, if implemented broadly across Edmonton, could achieve the City’s water quality targets.

Rural Stormwater Model Cover

Rural Stormwater Management Model

  • Completed for the Ausable-Bayfield Conservation Authority, as part of the Lake Huron Water Quality Initiative.
  • EOR, in coordination with PC-SWMM programmers CHI Inc, developed a new hydraulic model application for
    agricultural watersheds.
  • EOR modeled 5 agricultural priority areas for a total of 500 square km. Main features of this innovative model, included:
    -- ag-BMPs used in cold climates to improve runoff water quality,
    -- integration of seasonal changes in parameterization,
    -- more erosion equations built into the PC-SWMM sub-routines,
    -- incorporation of in-stream constituent removal processes
    -- specific drain tile drainage representation, and
    -- calibration using sensitivity-based radio tuning multi-threaded applications.
Thunder Bay Stormwater Management Plan Cover

Thunder Bay Stormwater Mgmt. Plan (SMP)

  • Developed SMP for the City and its seven upstream watersheds, as well as a Comprehensive Consultation Plan that engaged a large variety of project stakeholders.
  • Created a feasibility-level model for five key municipal areas and base models were developed for all watersheds.
  • The Plan assess the impact of future development and climate change on both infrastructure and the environment, as well as recommend strategies, policies, and standards to mitigate development impacts.
  • The Plan identifies retrofit options that will improve water quality and manage the system’s capacity.
  • Also created a 20-year Implementation Plan that provided an optimized and prioritized summary of the larger SMP.

McVicar Creek Protection and Rehabilitation Plan Cover

McVicar Creek Protection & Rehabilitation Plan

  • As the first Watershed Protection Plan completed in Thunder Bay, this plan provided a comprehensive assessment and detailed gap analysis of a 50 square km watershed (that supports a coldwater stream).
  • Incentive, regulatory, educational protection, and restoration strategies were identified and prioritized.
  • Implementation strategies were tailored based on the unique physical, social, and climatic characteristics of the community and watershed.
  • Over 50 stormwater retrofit projects were designed and vetted in preparation for future grant and educational campaigns.
