The Ottawa Hospital's new Civic development - Phase 2 parking garage, green roof and various supporting projects

Project description

The Ottawa Hospital is undertaking a phased process for establishing the new Civic development which will replace the aging Civic Campus located at 1053 Carling Avenue.

The new Civic development site, shown in the attached "detailed map" as the "Ottawa Hospital lease area," is an approximately 20-hectare property located south and west of the intersection of Carling Avenue and Preston Street. Phase 1 of the project included the development and approval of the master site plan, which have now been completed. Phase 2 is the first implementation phase, which will include the parking garage, green roof and various supporting projects, such as access roads, associated active transportation facilities and landscaping.

The Phase 2 project area is approximately five hectares, and will occupy the northeast section of The Ottawa Hospital lease area. The Phase 2 project area is bordered by Carling Avenue to the north, Preston Street to the east and Prince of Wales Drive to the southeast. The larger portion of the Phase 2 project area is located west of the existing Light Rail Transit (LRT) line, and consists mainly of open space and the lower portion of the treed escarpment. The smaller portion of the Phase 2 project area is located east of the LRT line, and currently has a surface parking lot on it. The Phase 2 project will extend over the existing Trillium LRT line. 

The parking garage is considered to be a key component of the master site plan of the new Civic development, as it will act as the staging area during construction of the new Ottawa Hospital. 

Responsible authorities

The Ottawa Hospital is leasing land from Public Services and Procurement Canada (PSPC) to carry out the new Civic development project. Because the project site is on federal land, a determination of environmental effects under the federal Impact Assessment Act (IAA, 2019) will be conducted.

In addition to PSPC, the National Capital Commission (NCC) has a role of approving this project under the National Capital Act, as part of the federal land use, design and transaction approval process. Both PSPC and the NCC are therefore acting as federal authorities undertaking the environmental effects determination for this project under the Impact Assessment Act (2019).

Some key considerations

Based on previous public consultations, the following elements have been considered and integrated into the project design and environmental effects determination:

  • The Trillium Pathway will be relocated, with temporary detours (along Carling Avenue and Preston Street) provided during construction.
  • As tree removal will be required for project implementation, a tree conservation and tree compensation strategy are being developed by The Ottawa Hospital.

The integration of an overall sustainable development approach (consideration of the project's carbon footprint, including the selection of building materials, incorporation of a green roof as part of the overall stormwater management strategy, replanting of trees, high modal targets for transit and active transportation) into the project design and implementation is currently being explored. The federal authorities will fold the sustainable development approach into the determination of environmental effects and the development of project mitigation measures.

Public consultation

The master site plan received significant public interest and input through public engagement activities carried out by The Ottawa Hospital and during the municipal development review process. Further public consultation will be carried out as part of the Phase 2 site plan control application to the City of Ottawa, and responses to public feedback received are identified as an application requirement through the NCC's federal approval process.
