9b.1.1.1 EM&A for landscape and visual resources shall be undertaken by the contractor during the design, construction and operation phases of the Project. This section presents the requirements of the baseline review, and the monitoring of the design, implementation and maintenance of the landscape and visual mitigation measures during the design, construction and operation phases of the Project.
9b.2.1.1
The
landscape and visual impact assessment of the EIA Study recommended a series of
mitigation measures to ameliorate the landscape and visual impacts of the
Project. The measures for both the
construction and operation phases as recommended in the EIA Report are summarized
in Table
9b.1.

|
MLVC-01 |
Grass-hydroseeded bare
soil surface and stock pile area |
|
MLVC-02 |
Landscape Design 1)
Early planting using fast grow trees and tall
shrubs at strategic locations within site as buffer to block view corridors
to the site from the VSRs, and to locally screen haul roads, excavation works
and site preparation works. 2)
Use of tree species of dense tree crown to serve
as visual barrier. 3)
Hard and soft landscape treatment (e.g. trees and
shrubs) of open areas within development to provide a background for the
outdoor containers from open view, shade and shelter, and a green appearance
from surrounding viewpoints. 4)
Planting strip
along the periphery of the project site. 5)
Selected tree species suitable for the coastal
condition. |
|
MLVC-03 |
Adoption of Natural Features of the Existing Shoreline 1)
Use of boulders in
different sizes and with the similar textures of the existing rocky shores
for the construction of breakwater and artificial shoreline in order to blend
into the existing natural shoreline. 2)
Use of cellular cofferdam together with the natural boulders to form a
curvature shoreline for the reclamation area to echo with the natural
shoreline of SKC. |
|
MLVC-04 |
Greening Design (Rooftop & Vertical Greening) 1)
Implementation of
rooftop and vertical greening (vertical building envelope) along the
periphery of each building block to increase the amenity value of the work,
moderate temperature extremes and enhance building energy performance. The
greening appearance of the building shall enhance its visual harmony with the
natural surroundings as well as reduce the apparent visual mass of the
structure. 2)
Sufficient space
between concrete enclosure and stack to minimize heat transfer. 3)
Introduction of
landscape decks at the stack to further enhance the overall natural and green
concept unique for this site. |

Mitigation for Visual Impacts |
|
|
MVC-01 |
Visual Mitigation and Aesthetic Design 1)
Use of natural
materials with recessive color to minimize the bulkiness of the building. 2)
Adoption of innovative aesthetic design to
the chimney to minimize or visually mitigate the massing of the chimney so as
to reduce its visual impact to the surroundings. 3)
Color of the
chimney in a gradual changing manner to match with the color of the sky. 4)
Provision of
observation deck for public enjoyment at the top of the chimney to diminish
the feeling of chimney. 5)
Provision of sky gardens between the two stacks to allow additional greening for enhancing the
aesthetic quality. Maintenance access (elevator and staircase) from the
ground floor to the sky gardens will be provided to allow maintenance of the
sky gardens. 6)
Integration of the
visitor’s walkway with different material façade design of incinerator plant
to enhance the aesthetic quality. |
|
MVC-02 |
Control of the security floodlight for construction areas at night to
avoid excessive glare to the surrounding receiver. |
|
MVC-03 |
Optimization of the construction sequence and construction programme
to minimize the duration of impact. |
|
MVC-04 |
Storage of the backfilling materials for site formation &
construction materials / wastes on site at a maximum height of |
|
MVC-05 |
Reduction of the number of construction
traffic at the site to practical minimum. |

Planting Maintenance Provision of proper planting maintenance and replacement of defective
plant species on the new planting areas to enhance aesthetic and landscape
quality. |

MVO-01 |
Environmental
Education Centre Development of an
Environmental Education Center, in which regular exhibitions and lectures to
promote environmental awareness and waste reduction concept would be
provided, as a part of the IWMF for the general public to alleviate negative
public perceptions of the development. |
|
MVO-02 |
Control of Light Control the numbers of lights and their
intensity to a level that is good enough to meet the safety requirements at
night but not excessive. |
|
MVO-03 |
Control of Operation Time Minimization of the frequency of waste
transportation to practical minimum (e.g. limit the reception of MSW from 8
am to 8 pm) |
9b.2.1.2
The mitigation measures during construction shall be
implemented from the commencement of the works and shall be applied for the
whole duration of the construction period.
The mitigation measures during operation will be included in the
detailed design and shall be constructed or built up during the construction. Management and maintenance for all mitigation
measures shall follow ETWB TCW No. 2/2004 Maintenance of Vegetation and Hard
Landscape Features.
9b.3.1.1 The contractor shall incorporate the recommended mitigation measures in the detailed design and shall ensure the potential conflicts of the mitigation measures with the works under the Project and other interfacing projects are resolved prior to construction.
9b.3.1.2 Audits of the detailed design against the recommendations of the landscape and visual impact assessments within the EIA should be undertaken by a Registered Landscape Architect (RLA), who should ensure the fulfilment of the intentions of landscape mitigation measures, and a Registered Architect (RA), who should ensure the fulfilment of the intentions of visual mitigation measures.
9b.4.1.1
A
baseline review shall be undertaken prior to the commencement of the
construction works. The purposes of the review are as follows:-
·
To check the status and any changes of the baseline
Landscape Resources, Landscape Character areas and Visually Sensitive Receivers
(VSRs) within and immediately adjacent to the works areas;
·
To determine whether amendments in the design of
the landscape and visual mitigation measures are required; and
· To recommend any necessary amendments to the design of the landscape and visual mitigation measures due to the above changes, if any.
9b.4.1.2
Any changes to the mitigation
measures that may be recommended as a result of the baseline review shall be
taken into account.
9b.5 Construction and Operation Phase Audit
9b.5.1.1
A
specialist Landscape Sub-Contractor (on the approved Government list) shall be
employed by the contractor for the implementation of landscape establishment
works and the compensatory planting, as well as the subsequent maintenance
operations during the one-year maintenance period which will be the first
operational year of the Project.
9b.5.1.2
All
landscape measures undertaken by both the contractor and the specialist
Landscape Sub-Contractor during the construction phase and the first year of
the operation phase shall be audited by a Registered Landscape Architect on a
regular basis to ensure compliance with the intended aims of the measures and
the effectiveness of the mitigation measures. Site inspections should be undertaken at least
once every two weeks throughout the construction period, and once every month
during the first operational year. After
the one-year maintenance period, the landscape maintenance and monitoring shall
be carried out by the Contractor.
9b.5.1.3
All
visual measures undertaken by the contractor and the specialist Landscape
Sub-Contractor during the construction phase and the first year of the
operation phase shall be audited by a Registered Architect on a regular basis
to ensure compliance with the intended aims of the measures and the
effectiveness of the mitigation measures. Site inspections should be undertaken
at least once every two weeks throughout the construction period, and once
every month during the first operational year.
9b.5.1.4
If
there is repeated non-compliance of the landscape and visual mitigation measures,
EPD shall be notified as necessary.
