Construction Phase
· Minimisation of runoff;
· Prevention or minimisation of the likelihood of the identified pollutants being in contact with rainfall or runoff; and
· Measures to abate pollutants in the stormwater runoff.
Runoff from Construction Site
1. High loading of suspended solids (SS) in construction site runoff shall be prevented through proper site management by the Contractor;
2. The boundary of critical work areas shall be surrounded by ditches or embankment. Accidental release of soil or refuse into the adjoining land should be prevented by the provision of site hoarding or earth bunds, etc. at the site boundary. These facilities should be constructed in advance of site formation works and roadworks;
3. Consideration should be given to plan construction activities to allow the use of natural topography of the site as a barrier to minimise uncontrolled non-point source discharge of construction site runoff;
4. Temporary ditches, earth bunds should be provided to facilitate directed and controlled discharge of runoff into storm drains via sand/ silt removal facilities such as sand traps, silt traps and sediment retention basin. Oil and grease removal facilities should also be provided where appropriate, for example, in area near plant workshop/ maintenance areas;
5. Sand and silt removal facilities, channels and manholes should be maintained and the deposited silt and grit should be removed regularly by the contractor, and at the onset of and after each rainstorm to ensure that these facilities area functioning properly;
6. Slope exposure should be minimised where practicable especially during the wet season. Exposed soil surfaces should be protected from rainfall through covering temporarily exposed slope surfaces or stockpiles with tarpaulin or the like;
7. Access roads should be protected by crushed rock, gravel or other granular materials to minimise discharge of contaminated runoff;
8. Slow down water run-off flowing across exposed soil surfaces;
9. Plant workshop/ maintenance areas should be bunded and constructed on a hard standing. Sediment traps and oil interceptors should be provided at appropriate locations;
10. Manholes (including newly constructed ones) should be adequately covered or temporarily sealed so as to prevent silt, construction materials or debris from getting into the drainage system;
11. Construction works should be programmed to minimise soil excavation works where practicable during rainy conditions;
12. Chemical stores should be contained (bunded) to prevent any spills from contact with water bodies. All fuel tanks and/ or storage areas should provided with locks and be sited on hard surface;
13. Chemical waste arising from the site should be properly stored, handled, treated and disposed of in compliance with the requirements stipulated under the Waste Disposal (Chemical Waste) (General) Regulation;
14. Drainage facilities must be adequate for the controlled release of storm flows.
15. Dredged materials requiring temporary storage on-site (for filling of marshland afterwards) should be securely stored and covered, if possible. Dried up mud materials can then be used for marshland formation.
Wastewater from Construction Site
1. Sewage generated from the construction workforce should be contained in chemical toilets before connection to public foul sewer can be provided. Chemical toilets should be provided at a minimum rate of about 1 per 50 workers. The facility should be serviced and cleaned by a specialist contractor at regular intervals;
2. Foul water from canteens should also be contained by chemical toilets before connection to public foul sewer can be provided;
3. Vehicle wheel washing facilities should be provided at the site exit such that mud, debris, etc. deposited onto the vehicle wheels or body can be washed off before the vehicles are leaving the site area;
4. Section of the road between the wheel washing bay and the public road should be paved with backfill to reduce vehicle tracking of soil and to prevent site run-off from entering public road drains;
5. Bentonite slurries used in diaphragm wall and bore-pile construction, etc. should be reconditioned and reused as far as practicable. Spent bentonite should be kept in a separate slurry collection system for disposal at a marine spoil grounds subject to obtaining a marine dumping licence from EPD. If used bentonite slurry is to be disposed of through public drainage system, it should be treated to meet the respective applicable effluent standards for discharges into sewers, storm drains or the receiving waters.
Oils and Solvents
1. Spillage of fuel oils or other polluting fluids should be prevented at source. It is recommended that all stocks should be stored inside proper containers and sited on sealed areas, preferably surrounded by bunds.
Draining of Fishpond Water
1. Through transferring the pond water within the subject site, the need of discharging pond water into the surrounding water bodies during the construction of the Project can be minimized.
2. Any draining of fishpond water should be handled with prudence. Water quality should be checked and monitored to ensure that relevant water quality criteria can be complied with the requirements as stipulated in the EM&A programme.
3. Sedimentation tanks should be set up at the construction site so that water to be discharged can be retained for sedimentation if any discharging activity is considered necessary.

Mitigation Measure |
CP1 |
Preservation
of Existing Vegetation - The development proposals would avoid disturbance
to the existing trees as far as practicable within the confines of both the
development site, Southern Development Access and the proposed Wetland Nature
Reserve (WNR). It is recommended that a full tree survey and felling
application will be undertaken and submitted for approval by the relevant
government departments in accordance with WBTC No. 03/2006, Management and
Maintenance of Natural Vegetation and Landscape Works, and Tree Preservation
during the detailed design phase of the project. Where possible all trees
which are not in conflict with the proposals would be retained and shall be protected
by means of fencing where appropriate to prevent potential damage to tree
canopies and root zones from vehicles and storage of materials.
Specifications for the protection of existing trees will be circulated for
approval by the relevant government authorities during the preparation of the
detailed tree survey. |
CP2 |
Preservation
of Existing Topsoil - Topsoil disturbed during
the construction phase will be tested using a standard soil testing
methodology and where it is found to be worthy of retention stored for
re-use. The soil will be stockpiled to a maximum height of |
CP3 |
Development
Site and Temporary Works Areas - The landscape of these works areas would be
restored following the completion of the construction phase. Construction
site controls shall be enforced, where possible, to ensure that the landscape
and visual impacts arising from the construction phase activities are
minimised including the storage of materials, the location and appearance of
site accommodation and the careful design of site lighting to prevent light
spillage. Screen hoarding may not be a practicable for this project due to
the viewing distances involved and the elevated viewing position of the
majority of VSRs. |
CP4 |
Mitigation
Planting - Replanting of disturbed vegetation
should be undertaken at the earliest possible stage of the construction phase
of the project and this should use predominantly native plant species. All
imported plants should be quarantined in local nursery for a minimum of 1
month to check there are no symptoms of infection by pests or diseases prior
to planting on site. It
is proposed that the origin of the trees be established through site visits
to the nursery. In addition, certain
trees will be brought to a temporary holding nursery at a small size as
early in the construction period as possible and grown to the semi-mature
size required as part of the proposed mitigation planting. This nursery will
be located either on site or within the local area. |
CP5 |
Transplantation
of Existing Trees - Existing trees to be transplanted
as shown in the Landscape Master Plan (approximately
28 trees), final recipient site will
subject to the findings of the detailed tree survey and felling application
undertaken at the detailed design stage |

OP1 |
Design of
Built Development - the proposed residential development will incorporate design
features including: ·
Stepped building height
principle
– The proposed residential blocks for Option ·
Building massing and
permeable development facade - the proposed use of slightly higher building
blocks for Option ·
Maintenance of existing
ridgeline and green backdrop – the proposed development form allows the
maintenance of the existing ridgeline and green backdrop to the south of the
development site even in relatively close views. This is achieved in Options ·
Colour treatment of
building facades - the architectural design for both Option ·
Underground car parking - the proposed
development for Options ·
Responsive building finishes - In terms of the building
finishes for Options ·
Responsive lighting design – Aesthetic design of architectural
and road lighting with following glare design measures: -
Directional and full cut off lighting is recommended
particularly for recreation and roadside areas to minimise light spillage to
the surrounding areas. -
Minimise geographical spread of lighting, only applied for
safety at the key access points and staircases; -
Limited lighting intensity to meet the minimum safety and
operation requirement; and -
High pressure sodium road lighting is recommended for more
stringent light control reducing spillage and thus visual impacts. |
OP2 |
Landscape
Buffer Planting – According to the guidelines provided in the Final Report of the
Fish Pond Study at Deep Bay Area, the buffer area will extend around the periphery
of the development to the proposed marsh habitat in WNR providing screening
of the development at low levels and creating a transitional structure, not
less than Apart from the landscape
buffer planting, some limited tree clusters will be planted on bunds within
the WNR to facilitate the establishment of habitat for different
bird species. The primary objective of the tree planting within the WNR
will be ecological in the creation of a favourable habitat for birds rather
than for amenity purposes. As such within the fishpond or freshwater
marshland area, trees will be planted in small clusters in positions designed
not to intrude upon the bird flight lines, create enclosure or shade the
marshland and fishponds. Some fruit-bearing trees, such as Ficus hispida, Ficus microcarpa and Melia
azedarach, are recommended from ecological perspectives to enhance
foraging opportunities for some bird species. Whilst wide canopied tree
species such as Ficus microcarpa in
combination with bamboo species such as Bambusa
eutuldoides are recommended to be planted at the edge of the alternative
egretry I in order to provide a favourable habitat for the egrets and screen
the area from human activity. |

Compensatory Planting Proposals - the planting
proposals for the residential amenity areas and landscape woodland buffer areas
presented as Figure 11-12, Landscape Master Plan include some 300 new
specimen trees in addition to the 3750 square metres of mass woodland
planting described under OP2 above would be established within the project
boundary. The proposed planting of some 1050 trees will result in a
compensatory planting ratio of 2.6:1 (new tree planting: trees recommended
for felling). This compares favourably with the report's assertion that some
399 trees would be felled due to the proposals in this area. Following the
retention of existing trees, the successful establishment of newly planted
trees and the transplantation of some of the existing trees, the project area
will contain approximately 1316 trees. Trees forming part of the landscape
buffer area will utilise species native to |

Note: * The action levels and actions will be established after 2 years
for the communities of those species groups (ie aquatic invertebrates,
freshwater fish and marsh bird species) which are currently not features of the
existing FLW fauna. That is action levels and actions can only be established
once the communities have become established and it becomes clear what their
composition and relative abundance is.
