St. Catharines Airport Zoning Regulations — (a)
The approach surfaces, shown on St. Catharines Airport Zoning Plan No. 26-047-81-67, Sheets 1, 2, 4, 5, 6, 8, 9, 10, 11 and 12 dated March 30, 1984, are surfaces abutting each end of the strips associated with the runways designated 06-24, 10-28 and 01-19 and are described as follows: (a) a surface abutting the end of the strip associated with runway approach 06 consisting of an inclined plane having a ratio of 1 m measured vertically to 50 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 15 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 2 400 m from the projected centre line; said imaginary horizontal line being 300 m above the elevation at the end of the strip; (b) a surface abutting the end of the strip associated with runway approach 24 consisting of an inclined plane having a ratio of 1 m measured vertically to 50 m measured horizontally diverging at a rate of 15% from each side of the strip end and rising to its intersection with the Canada-United States International Boundary; (c) a surface abutting the end of the strip associated with runway approach 10 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 500 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 280 m from the projected centre line; said imaginary horizontal line being 62.5 m above the elevation at the end of the strip; (d) a surface abutting the end of the strip associated with runway approach 28 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 400 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 280 m from the projected centre line; said imaginary horizontal line being 62.5 m above the elevation at the end of the strip; (e) a surface abutting the end of the strip associated with runway approach 01 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 500 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 280 m from the projected centre line; said imaginary horizontal line being 62.5 m above the elevation at the end of the strip; and (f) a surface abutting the end of the strip associated with runway approach 19 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 500 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 280 m from the projected centre line; said imaginary horizontal line being 62.5 m above the elevation at the end of the strip.
