Runway Extensions Assessment Update

The Impact Assessment Agency of Canada (IAAC) Virtual Information Sharing Sessions (September 8, 2020)

On August 28, 2019 the Impact Assessment Act (IAA) was enacted and the Impact Agency of Canada (IAAC) was formed. The IAA is an update to the federal consultation process that focuses on health, social and economic impacts. The Region of Waterloo International Airport runway extensions project is subject to this act. 

Due to COVID-19 and the associated physical distancing and self-isolation measures, the Agency hosted two virtual information sharing and discussion sessions on September 8, 2020. The objectives of the sessions were to help better understand how to participate in the upcoming impact assessment process, and to hear any comments on the Project to inform the proponent’s Initial Project Description. Each session included a presentation by representatives from the Agency and the Region of Waterloo International Airport. Participants had the opportunity to ask questions.

On November 2, 2021, the Agency determined that a full impact assessment under the Impact Assessment Act is not required for the Runway 14-32 extension project.

Currently, Runway 14-32 can accommodate light general aviation aircraft and flight training activity. Runway 08-26 can accommodate larger narrow-body aircraft (i.e. Boeing 737 aircraft with one aisle). Wide-body aircraft (i.e. Boeing 767 aircraft with two aisles) cannot use the airport at this time, and there is no secondary option for narrow-body aircraft. This restricts larger aircraft from operating in poor weather conditions, such as rain, ice or high winds.

Extending Runway 14-32 to a length of 2,134 metres (7,000 feet) will improve the safety and reliability of the airport. When Runway 08-26 has strong cross-winds combined with wet or icy conditions, larger narrow-body aircraft would be able to land on Runway 14-32. Additionally, scheduled air service could use Runway 14-32 when Runway 08-26 is closed for repairs.

Extending Runway 08-26 to a length of 2,663 metres (8,737 feet) will reduce the restrictions on larger aircraft operating in poor weather. It will also allow wide-body aircraft to use the airport, which need the extended length.

The runway extensions design generally includes the following:

• Extend Runway 14 by 555 metres (1,820 feet) (northwest towards Breslau);
• Extend Runway 32 by 329 metres (1,080 feet) (southeast towards Cambridge);
• Extend Runway 26 by 529 metres (1,737 feet) (west towards Guelph);
• Construct taxiways parallel to the runway extensions;
• Construct access roads around the runway extensions;
• Move Runway 26 approach lighting;
• Install new approach lighting for Runway 14;
• Move or upgrade other visual aids;
• Move or tunnel Shantz Station Road; and,
• Upgrade how aircraft maneuver around airport

The Region will follow the Canadian Environmental Assessment Act (CEAA) process. The runway extensions trigger this process because the size of aircraft will increase.

• Update Airport Zoning Regulations;
• Removal of trees and other potential obstacles;
• Buy property for runway extensions;
• Natural environment;
• Archaeological resources;
• Heritage resources;
• Contaminated soil/groundwater; and,
• Noise.

The Region has begun the process of updating the current Airport Zoning Regulations. This process will include an assessment of obstacles that interfere with the AZRs. Visit our Airport Zoning Regulation page for an explanation of AZRs.

One goal of the planning process is to limit the impact to adjacent properties and the need to buy land. The Region owns the land required for all runway extensions and parallel taxiways. However, additional adjacent land may help limit the impact to airport operations.

The Runway 14-32 extensions will impact the east branch of the Randall Drain, some wetlands, and potential wildlife, fish and species at risk habitat. The Runway 26 extension will impact the east branch of the Randall Drain and some species at risk habitat.

To determine the best mitigation measures, more investigation and consultation with approval agencies is required. Mitigation measures and compensation will be considered, including:

• Scheduling construction work to avoid critical breeding or migration periods;
• Erosion and sediment control;
• Re-vegetation/compensation; and,
• Fencing.

Consultants have completed a Stage 1, 2 and 3 archaeological investigation. Stage 1 is a desktop study of known and potential areas of archaeological interest. A Stage 2 assessment was completed for several additional areas, which consists of a walking survey and/or hand test pits to determine if any buried archaeological resources exist. A Stage 3 assessment was then completed, which includes a more thorough investigation in areas where a significant number of artifacts were found. It was determined that a Stage 4 investigation was not required.

Consultants have completed a Built Heritage and Cultural Heritage Landscape Assessment. No heritage resources are directly impacted. The airport may fence or screen the runways from potential heritage resources.

Consultants have completed a desktop investigation of past land use. Due to old fuel tanks, possible spills, etc. contaminated soil may exist. A geotechnical investigation will be completed to assess the soil and groundwater conditions. This will determine if excess soil requires proper disposal offsite, or if groundwater requires pumping and treatment.

The 2017 Airport Master Plan developed Noise Exposure Forecasts (NEF) for the year 2035. This forecast included the future Runway 14, 26 and 32 extensions.

View a drawing of the comparison between the current 2000 NEF and the future 2035 NEF.

The NEF contour comparison shows that noise will be similar, with increases in some areas and decreases in others. In general, noise in Kitchener and Breslau is not expected to increase beyond the current 2000 NEF.

The impact of NEF contours can generally be summarized as follows:

• 25 NEF – impacts to areas sensitive to noise, some annoyance to residential areas;
• 30 NEF – impacts to residential areas, some speech interference; and,
• 35 NEF – impacts to most land uses.

Residential development is not permitted within the 30 NEF contour of the current 2000 NEF.

• $55,000,000 to construct the Runway 14-32 extensions; and,

• $37,000,000 to construct the Runway 08-26 extension, excluding Shantz Station Road.

• Detailed design of the Runway 14-32 extensions will be complete by the end of 2023.
• Construction of the Runway 14-32 extensions would begin once funding is established (as early as 2024).
• Detailed design of the Runway 26 extension is anticipated in 2028
• Construction of the Runway 26 extension would begin following completion of the design (anticipated 2029).
