Edmonton Garrison Heliport Zoning Regulations — (a)
The approach surfaces associated with the heliport and shown on the Plan are described as follows: (a) an imaginary inclined plane extending upward and outward from the intersection of imaginary vertical planes passing through the heliport boundary, with imaginary horizontal planes lying 2 m above the general ground level of the heliport boundary at any point thereon, to a maximum elevation of 792 m above sea level at the outer limit of the approach surface, being 115 m, more or less, above the assigned elevation of the heliport zoning reference point, such outer limit being a circle of radius 5,000 m centred on the heliport zoning reference point; (b) a surface abutting the end of the strip associated with runway approach 11 consisting of an inclined plane having a ratio of 1 m measured vertically to 20 m measured horizontally, rising to an intersection with the outer limit of the approach surface described in paragraph (a), thence said approach surface slopes upward at the 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 379.4 m measured vertically above the assigned elevation at the end of the strip; (c) a surface abutting the end of the strip associated with runway approach 29 consisting of an inclined plane having a ratio of 1 m measured vertically to 20 m measured horizontally, rising to an intersection with the outer limit of the approach surface described in paragraph (a), thence said approach surface slopes upward at the 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 389 m measured vertically above the assigned elevation at the end of the strip; (d) a surface abutting the end of the strip associated with runway approach 02 consisting of an inclined plane, having a ratio of 1 m measured vertically to 20 m measured horizontally, rising to an intersection with the outer limit of the approach surface described in paragraph (a), thence said approach surface slopes upward at the 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 403.3 m measured vertically above the assigned elevation at the end of the strip; and (e) a surface abutting the end of the strip associated with runway approach 20 consisting of an inclined plane having a ratio of 1 m measured vertically to 20 m measured horizontally, rising to an intersection with the outer limit of the approach surface described in paragraph (a), thence said approach surface slopes upward at the 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 430.9 m measured vertically, above the assigned elevation at the end of the strip.
