Airport vicinity protection area


​​​

​​​Administration and the Calgary Airport Authority (Airport Authority) have been engaged in collaborative discussions regarding a potential amendment to the Calgary International Airport Vicinity Protection Area (AVPA) Regulation to allow for residential intensification within certain areas of the 30-35 Noise Exposure Forecast protection area.

Background

The Alberta government enacted the Airport Vicinity Protection Area (AVPA) regulation in 1979 to govern development close to the Calgary International Airport. This prevents land from being developed near the airport that will negatively affect airport operations, including its runway arrivals and departures.

The regulation establishes uses that are not allowed within certain locations, identified as Noise Exposure Forecast (NEF) areas, due to potential noise impacts from aircraft flying over communities as they arrive or depart. While existing residences in the area are allowed, subdivision and redevelopment in residential areas that increases the number of dwelling units is currently prohibited in the NEF 30+ areas.

Update on Council direction

Throughout 2018, Administration had been in discussions with The Province of Alberta and the Calgary Airport Authority. Through the collaborative discussions, Administration and the Airport Authority shared their objectives, raised key issues, and assessed information related to noise complaints and potential residential growth. Both parties agreed that they share the objective of supporting the continued growth of the airport and associated logistics hub, recognizing its important role in the economic development of the city.

Further, Administration shared its strategic objectives as outlined in the Municipal Development Plan (MDP), Transit Oriented Development Policy Guidelines and resulting objectives of the draft Historic East Calgary Area Redevelopment Plan. The Airport Authority communicated their objective of supporting the continued growth of airport operations while respecting overall community safety and well-being. On December 17, 2018, Administration presented draft AVPA Regulation amendments to Council. Council directed Administration​ to continue conversations with the Calgary Airport Authority and meet with affected communities.

In February 2019, a proposed amendment to the AVPA was submitted to The Province of Alberta for review. However, the timing for the provincial review of the proposed amendment is undetermined at this time. The proposed changes are similar in nature to the draft changes Administration presented to Council on December 17, 2018.

Previously, in December of 2016, Council directed Administration to develop amendments to the Calgary International Airport Vicinity Protection Area (AVPA) Regulations. This work required discussions with The Province of Alberta and the Calgary Airport Authority. The discussions considered exemptions to the AVPA Regulations to allow for:

  • a range of low density residential development and small-scale subdivision in all areas affected by the Noise Exposure Forecast (NEF) 30 contour area;
  • a range of low density residential redevelopment including secondary suites and small-scale subdivision in all areas affected by the NEF 30 contour area; and
  • support for exemptions for higher intensity residential development in important intensification areas within the 30 NEF contour area in Inglewood.

AVPA Regulation Overview

Noise Exposure Forecast areas

Noise exposure forecast (NEF) areas are established by Transport Canada. These areas are determined based on a measurement of actual and predicted aircraft noise in the vicinity of airports. They consider how the human ear reacts to specific aircraft noise, including factors like noise volume, frequency, duration, time of the occurrence and tone. Also taken into consideration is the amount of air traffic arriving and departing, aircraft type, current runway locations and future runway needs.

Prohibited uses

Due to the increased noise impacts, certain land uses are prohibited within the different NEF areas, as shown on the chart below.
Residential Uses
Although existing residences are allowed, current AVPA regulations prohibit certain residential developments within the NEF 30+ areas. This means that:

  • Existing residential properties cannot be subdivided to create new residential lots.
  • The number of residential units on these properties cannot increase.

Note: theserules apply even if the Calgary Land Use Bylaw shows your property is eligible for these forms of redevelopment.
Secondary Suites

The regulation now allows secondary suites to be developed within the NEF 30+ areas in limited circumstances. The suite must be located in the basement of an existing single family development. A secondary suite would still require City approvals such as a development and building permit.

​Building code - acoustical requirements

Part 11 of the Alberta Building Code (ABC) 2014 contains exterior acoustic insulation requirements in buildings constructed within the Airport Vicinity Protection Area (AVPA). Exterior acoustic insulation is capable of reducing aircraft noise in buildings and can be provided in specially constructed roofs, exterior walls, windows and doors.
The current edition of the Municipal Government Act, Calgary International AVPA regulation defines the location and extent of the AVPA and specifies what land uses are permitted to be developed within.
Part 11 of the ABC only applies to buildings that are permitted to be constructed within the AVPA. New residences are not permitted to be constructed within much of the AVPA.
If a building is permitted to be constructed, different levels of noise reducing insulation are required for different types of rooms within the building. There are four levels of noise reducing insulation required.

  1. Sleeping rooms are required to have the highest level of noise reducing insulation.
  2. The second highest level is required for living rooms, dining rooms, recreational rooms and classrooms.
  3. The third highest level is required for kitchens, bathrooms, laundry rooms, private offices, conference rooms and meeting rooms.
  4. The lowest level is required for general offices, reception areas and other types of rooms not mentioned above.

The roofs, exterior walls, windows and doors enclosing each of these spaces must be constructed with noise-reducing features, to reduce the amount of aircraft noise that can get into the room. Part 11 of the ABC provides advice to designers on how to design the roofs, exterior walls, windows and doors in order to provide the appropriate level of exterior acoustic insulation.

The calculations needed to determine the appropriate level of exterior acoustic insulation are complex. In practice, professional engineers complete the calculations and submit a summary report or letter to The City during the building permit review process.​​​​​​​​​​​​​​​​​​​
