4.1
The landscape and visual mitigation measures should be
incorporated in the detailed design, so as to ensure the effectiveness of the
mitigation measures described in Table 5.4, Section 5 of EIA report. Any changes to the mitigation measures
that may be recommended to match the baseline review result or to match the
ongoing EM&A should also be incorporated in the detailed design.
4.2
The design, implementation and maintenance of mitigation
measures should be checked regularly to ensure that they are fully
realised. Any potential conflicts
among the proposed mitigation measures, the project works, and operational
requirements should also be identified and resolved early. The proposed mitigation measures should always
be given priority.
4.3
A landscape specialist with substantial site experience
should be responsible for supervising the landscape works during the
Construction Phase to ensure the mitigation measures are implemented according
to Table 5.4 Section 5 of EIA Report.
4.4
The implementation of landscape construction works and
maintenance operations during the subsequent 12 month Establishment Period must
be supervised by landscape specialist. The employment of a landscape specialist
for monitoring the tree protection measures is cited in the EIA as a mitigation
measure, and their involvement should be monitored.
4.5
Measures to mitigate landscape and visual impacts during
construction, should be checked regularly to ensure compliance with the
intended aims of the measures.
4.6
The extent of the agreed works areas should be regularly
checked during the construction phase.
Any trespass by the Contractor outside the limit of the works, including
any damage to existing trees shall be reported to the appropriate
authorities.
4.7 The progress of the engineering works should be regularly reviewed on site to identify the earliest practical opportunities for the soft landscape works to be undertaken.

4.8
Potential landscape and visual impacts have been carefully
considered during the development of the project design to (1) avoid impacts on
important landscape resources including the Forbes Street tree wall (LR1.2) and
KGV Park tree wall(LR1.6), as well as old and valuable trees in the LCSD
registry, as the first priority; and (2) locate, design and reduce physical
extent of the works as far as possible, as well as identify mitigation
measures, so as to minimize impacts on existing trees and open spaces, and to
minimize the degree of visual impact, as proposed below.

Re-use of Existing Soil Existing topsoil shall be re-used where possible for new

No-intrusion Zone To maximize protection to existing trees, ground
vegetation and the associated understory habitats, construction contracts may
designate “No-intrusion Zone” to various areas within the site boundary with
rigid and durable fencing for each individual no-intrusion zone. The
contractor should close monitor and restrict the site working staff not to
enter the “no-intrusion zone”, even for non-direct construction activities
and storage of equipment. |

Aesthetic design of the conveyor belt system The removal of excavated material requires installation of
a conveyor and a barging point. The conveyor will be covered, except the
portion where it meets the barging point. The aim of covering or enclosing
the conveyor is to avoid noise and air quality issues; however, the conveyor
where above-ground should be adequately screened and /or constructed of
suitable materials and in colours/tones that minimize visual intrusion. |
