I will arrange for the Department to forward the documentation requested by the Deputy as soon as possible. However, it will take some time to retrieve the material.

The Red Zones referred to by the Deputy are not two-dimensional surfaces on the ground. They are referred to as obstacle limitation surfaces and would best be described as wedge-shaped. As a result of their shape the zone for each runway would not be of constant value due to the typography of the terrain. The Department's policy states that each zone is the same length of 1,370 metres. However, in 1998 South Dublin County Council reduced this length by 100 metres for Runway 05.
