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.

Council direction

In December 2016, Council directed Administration to develop amendments to the Calgary International Airport Vicinity Protection Area (AVPA) Regulations (PUD2016-0904 and PUD2016-0905). This work required discussions with The Province of Alberta and the Calgary Airport Authority. The discussions should consider 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
  • seek support for exemptions for higher intensity residential development in important intensification areas within the 30 NEF contour area in Inglewood.

City discussions with the Province of Alberta and the Calgary Airport Authority

Throughout 2018, Administration has been in discussions with The Province of Alberta and the Calgary Airport Authority. From July 2018 to November 2018, Administration and the Calgary Airport Authority worked on the content of the proposed amendment to the AVPA Regulation that were directed by Council.

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 Inglewood 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.

Agreement has been reached to jointly seek changes to the AVPA Regulation. These changes are considered by both parties to uphold the shared objective of supporting the continued growth of the airport and associated logistics hub, while allowing for residential intensification, supporting transit ridership and increasing housing choice.

Proposed amendment

The Airport Authority and Administration jointly developed a request for amendments to the AVPA Regulation to allow for residential intensification within the protection area. The proposed changes to the AVPA Regulation are as follows:

  1. Removal of restrictions on secondary suites and backyard suites from existing residential lots in the communities of Mayland Heights, Vista Heights and Inglewood (refer to Attachment 3);
  2. Allow for low density residential infill, including single lot subdivision for additional single-detached dwellings and semi-detached dwellings in the communities of Mayland Heights, Vista Heights and Inglewood;
  3. Allow for row housing without secondary suites at end block locations within the communities of Mayland Heights and Vista Heights;
  4. Allow for row housing with secondary suites at end block locations within the community of Inglewood in recognition of the new Bus Rapid Transit station and proximity of the 9th Avenue SE Main Street; and
  5. No further requests for amendments or exemptions are to be submitted by The City of Calgary for 10 years.

 If the proposed amendment is supported by Council, The City will submit an application jointly with the Calgary Airport Authority, to The Province of Alberta, requesting the amendment to the Calgary International Airport Vicinity Protection Area (AVPA) Regulations.

 To learn more please read the Proposed Amendment that will be presented to Council.

Reporting to Council (2018)

On December 3, 2018, Administration will bring forward a report to the Standing Policy Committee (SPC) on Planning and Urban Development (PUD). There is an opportunity for the public to speak during this meeting. It is planned that on December 10, 2018, Administration will request a resolution of Council, supporting the proposed amendment.

The SPC on PUD report can be found here.

 2016 engagement

In 2016, Administration hosted two open houses and provided an online questionnaire regarding a proposed amendment to the AVPA Regulation to exempt residential development from the current restrictions in the 30-35 NEF contour area, specifically within the community of Inglewood. The first open house was held on 2016 June 21, as part of a larger Inglewood Ramsay Area Redevelopment Plan event. In response, 28 comment forms were received. The second open house was held at the Inglewood Community Association Hall on 2016 September 13, whereby 34 people were in attendance and 11 comment forms were received. In addition to the engagement events, letters were sent to all affected property owners. To learn more please review the What we Heard Report​

For landowners in Inglewood, Mayland Heights, and Vista Heights

If the proposed amendment is supported by Council, and then approved by The Province of Alberta, landowners in Inglewood, Mayland Heights, and Vista Heights will have more flexibility in regards to low-density forms of development they can construct on their properties without requiring an exemption. The table below illustrates what is proposed in the amendment:


​Secondary Suites and Backyard Suites ​Single lot subdivision to allow for an additional single detached dwelling or a semi-detached dwelling Up to four units (e.g. rowhouse buildings or townhouses) on corner lots
​​Inglewood​ ​Yes ​Yes ​Yes – with suites
​Vista Heights ​Yes ​Yes ​Yes – without suites
​Mayland Heights ​Yes ​Yes ​Yes – without suites​

Background

Overview

The Alberta government enacted the Airport Vicinity Protection Area (AVPA) regulation in 1979 to govern land use development close to the Calgary International Airport. This prevents land uses 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 that increases the number of dwelling units is currently prohibited in the NEF 30+ areas.


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.

Inglewood and other NEF-30 areas

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

The AVPA Regulation was amended by the Province of Alberta in 2017. 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 Permit 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.
