Environmental Outcomes/Benefits and Mitigation Measures |
|
Population
and environmentally sensitive areas protected |
If all helicopters are operated
at the proposed new helipad, the Shun Tak Centre Offices would provide noise
screening effect to about 12,000 people at residential buildings within 500m
of the study area. |
|
Area/Issue |
Environmental Outcomes/Benefits and Mitigation Measures |
|
Environmentally
friendly designs recommended |
The proposed helipad is located
behind the Shun Tak Centre which would provide screening effect to the nearby
noise sensitive receivers. |
|
Key
Environmental Problems Avoided |
(1) The helicopter noise
exceedance arising from proposed new helipad alone would be avoided or (2) the cumulative noise levels from the
existing and new helipads at the representative NSRs would not be worse than
the existing allowable helipad operation conditions (less than 1.0 dB(A)
increase) as (i)
Proposed helipad is located behind Shun Tak Centre
such that many noise sensitive receivers have no direct line of sight on the
helicopter operation during hovering and idling mode; (ii)
The use of noisy helicopter S92 or helicopter with
noise emission larger than helicopter S76C+ is not recommended for proposed new
helipad; (iii)
flight
frequency arrangement control. |
