Cold Lake Airport Zoning Regulations — (a)
The approach surfaces, shown on Department of Public Works Plan No. E.1898, dated February 5, 1986, are surfaces that abut each end of the strips associated with the runways designated 03-21, 12L-30R and 12R-30L, and that are more particularly described as follows: (a) a surface that abuts the end of the strip associated with runway 03 and consists of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally rising to an intersection with the outer surface; thence said approach surface shall slope upward at a ratio of 1 m measured vertically to 50 m measured horizontally and rise 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 291.2 m measured vertically above the assigned elevation at the end of the strip; (b) a surface that abuts the end of the strip associated with runway 21 and consists of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally rising to an intersection with the outer surface; thence said approach surface shall slope upward at a ratio of 1 m measured vertically to 50 m measured horizontally and rise 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 291.0 m measured vertically above the assigned elevation at the end of the strip; (c) a surface that abuts the end of the strip associated with runway 12L and consists of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally rising to an intersection with the outer surface; thence said approach surface shall slope upward at a ratio of 1 m measured vertically to 50 m measured horizontally and rise 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 291.0 m measured vertically above the assigned elevation at the end of the strip; (d) a surface that abuts the end of the strip associated with runway 12R and consists of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally rising to an intersection with the outer surface; thence said approach surface shall slope upward at a ratio of 1 m measured vertically to 50 m measured horizontally and rise 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 291.0 m measured vertically above the assigned elevation at the end of the strip; (e) a surface that abuts the end of the strip associated with runway 30L and consists of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally rising to an intersection with the outer surface; thence said approach surface shall slope upward at a ratio of 1 m measured vertically to 50 m measured horizontally and rise 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 291.4 m measured vertically above the assigned elevation at the end of the strip; and (f) a surface that abuts the end of the strip associated with runwa
