Chenier Subdivision


City of Ottawa


Ottawa, Ontario

Construction Value




Key Features

  • A stormwater management facility to provide the required quantity storage for the site and existing tributary areas.
  • A secondary storm sewer within the right-of-way to provide an outlet for the facility.
  • The grading design for the 6.8 hectare site included over 1000 metres of residential roadways and individual lot grading.
  • Due to the elevations of the existing infrastructure, the site required approximately 3 m of fill to bring the site to the final design grade.
  • The site servicing included over 1000 metres of water, storm and sanitary sewers connecting to the existing infrastructure within Elm Crescent.

Project Description

Robinson Land Development (RLD) were retained to provide detailed servicing, grading, and stormwater management design for a proposed residential subdivision located at 6279 Fernbank Road in the City of Ottawa, Ontario. The proposed infill subdivision includes a variety of townhome blocks, semi-detached dwellings and single-family homes for a total of 148 residential units. Included in the development design is a park space, stormwater management (SWM) facility and an oil grit separator to provide quality treatment.

Due to the scrutiny associated with the project the design was constrained by decisions resulting from the Ontario Municipal Board (OMB) process in addition to City of Ottawa special requests (such as reducing the storm outflow from the site). The subdivision is also adjacent to an Urban Natural Feature (UNF) along the eastern boundary and bounded by existing residential homes around the remaining site perimeter which provided a challenge with respect to the grading drainage and SWM design.

Due to the complexity of the stormwater management, RLD worked in conjunction with J.F. Sabourin and Associates Inc. in modelling of the stormwater flows and access the interaction of the proposed development with the adjacent UNF.
