Being a surface abutting each end of the strips associated with the runways designated 13L-31R, 13R-31L and 18-36, and more particularly described as follows: (a) a surface abutting the end of the strip associated with runway approach 13L consisting of an inclined plane having a ratio of one (1) foot measured vertically to fifty (50) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, two hundred (200) feet measured vertically above the elevation at the end of the strip and ten thousand (10,000) feet measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being two thousand (2,000) feet from the projected centre line, (b) a surface abutting the end of the strip associated with runway approach 13R consisting of an inclined plane having a ratio of one (1) foot measured vertically to fifty (50) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, two hundred (200) feet measured vertically above the elevation at the end of the strip and ten thousand (10,000) feet measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being two thousand (2,000) feet from the projected centre line, (c) a surface abutting the end of the strip associated with runway approach 18 consisting of an inclined plane having a ratio of one (1) foot measured vertically to forty (40) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, one hundred and fifty-two (152) feet measured vertically above the elevation at the end of the strip and six thousand and eighty (6,080) feet measured horizontally from the end of the strip, the outer end of the imaginary horizontal line being eight hundred and fifty-eight (858) feet from the projected centre line, (d) a surface abutting the end of the strip associated with runway approach 31R consisting of an inclined plane having a ratio of one (1) foot measured vertically to fifty (50) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, two hundred (200) feet measured vertically above the elevation at the end of the strip and ten thousand (10,000) feet measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being two thousand (2,000) feet from the projected centre line, (e) a surface abutting the end of the strip associated with runway approach 31L consisting of an inclined plane having a ratio of one (1) foot measured vertically to fifty (50) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, two hundred (200) feet measured vertically above the elevation at the end of the strip and ten thousand (10,000) feet measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being two thousand (2,000) feet from the projected centre line, and (f) a surface abutting the end of the strip associated with runway approach 36 consisting of an inclined plane having a ratio of one (1) foot measured vertically to forty (40) feet measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip, one hundred and fifty (150) feet measured vertically above the elevation at the end of the strip and six thousand and eighty (6,080) feet measured horizontally from the end of the strip, the outer end of the imaginary horizontal line being eight hundred and fifty (850) feet from the projected centre line, which approach surfaces are shown on Department of Transport Plan No. E.1012 dated January 19, 1972.
