Zoning

Saskatoon Airport Zoning Regulations are a Federal Regulation made pursuant to the Aeronautics Act. The purpose of these regulations is to protect the ongoing viability of airspace adjacent to the airport for arrivals and departures to be conducted in a safe manner. Obstacle Limitations Surfaces as defined by Saskatoon Airport Zoning Regulations restrict the height of objects (both natural and man-made) in and around the airport in order to achieve this level of safety.

The following definitions describe the major components of the Saskatoon Airport Zoning Regulations;

Airport Reference Point: a point in the approximate geometric centre of the aerodrome which defines the centre of the Outer Surface and which has an assigned elevation equal to the lowest point on the runway surfaces.

The following describes the 3 obstacle limitation surfaces (as shown in yellow on the diagram found here) which restrict both natural and man-made objects surrounding the airport:

Outer Surface: an irregular shaped surface which surrounds the airport to an approximate distance of 4km from the centre of the Airport Reference Point. This surface restricts building heights to 45m above the assigned elevation of the Airport Reference Point. The elevation of the Aerodrome Reference Point is set at 500.23 msl.

Take-Off/Approach Surface: is an imaginary trapezoidal surface with 1:50 slope which extends out 15,000m from the ends of each runway strip. The elevation of the beginning of the Take-Off/Approach surface is equal to the elevation of the runway threshold which it serves.

Transition Surface: is an imaginary complex shaped surface with 1:7 slope which extends out from the edge of each runway strip and along side of the associated Take-Off/Approach Surface (perpendicular to the centerline and extended centerline of the runway) and extends upwards to a point 45m above the assigned elevation of the Airport Reference Point.​
