• Pond and bio-swale
(b) Construction of landscape softworks, including
• Tree planting
• Shrub planting
• Groundcover planting
• Turfing
• Hydroseeding
• Roof greening
• Vertical greening
• Roadside planting and planting along the edge of the reclamation is proposed;
• Transplanting of mature trees in good health and amenity value where appropriate and reinstatement of areas disturbed during construction by compensatory hydro-seeding and planting;
• Protection measures for the trees to be retained during construction activities;
• Optimizing the sizes and spacings of the bridge columns;
• Fine-tuning the location of the bridge columns to avoid visually-sensitive locations;
• Aesthetic design of the bridge form and its structural elements for HKLR, e.g. parapet, Soffit, columns, lightings and so on;
• Considering the decorative urban design elements for HKLR, e.g. decorative road lightings;
• Maximizing new tree, shrub and other vegetation planting to compensate tree felled and vegetation removed;
• Providing planting area around peripheral of HKLR and HKBCF for tree planting screening effect;
• Providing salt-tolerant native trees along the planter strip at affected seawall and newly reclaimed coastline;
• For HKBCF, providing aesthetic architectural design on the related buildings (e.g. similar materials for PCB building facade to Airport buildings, roof planting and subtle materials for other facilities buildings and so on), and the related infrastructure (e.g. parapet planting and transparent cover for elevated footbridges) to provide harmonic atmosphere of the HKBCF;
• Fine-tuning the sizes of the structural members to minimize the bulkiness of buildings and adjustment of building arrangement to minimise disturbance to surrounding vegetation in the HKBCF; and
• For HKLR, providing aesthetic design on the viaduct, tunnel portals, at-grade roads and reclamation (e.g. subtle colour tone and slim form for viaduct to minimize the bulkiness of the structure and to blend the viaduct better with the background environment, featured form of tunnel portals, roadside planting along at-grade roads and landscape berm on & planting along edge of reclamation area) to beautify the HKLR alignment.
• Zone 1
Only grass and ground cover of less than 200mm in height; climbers that do not produce fleshy fruit and should be planted in areas not exceeding 25m2 and regularly pruned shrubs that do not produce fleshy fruit and are of less than 1.5m in height and 25m2 in area size are allowed.
• Zone 2
Climbers, palms, cycad, trees or shrubs are acceptable only if they do not produce fleshy fruit. As a precautionary measure, height restriction of newly planted palms, cycad and tree is normally 5-10m, and trees that could produce a spreading crown and/or develop into a tall structure should be avoided. Hence, selection of small trees is preferred as a long-term management and maintenance approach. For all existing, planted palms, cycad and trees, their suitability and horticultural maintenance practice will be regularly reviewed by AAHK, and will be monitored for bird activities and potential hazard to aircraft by AA¡¦s Wildlife Hazard Consultant. Given that the mature size of certain existing tree species (such as Casuarina equisetifolia and Delonix regia) is up to 10-15m, close monitoring on their bird attractiveness of these particular trees would be carried out. Height restriction of existing and newly-planted shrubs is 1.5m.
For initial planting, palm / cycad / ravenala / bamboo / trees should be in groups of 50 individuals or fewer. The area of each tree group should not exceed 150m2, and shrubs / climbers should be planted in areas of no more than 500m2. Routine horticultural maintenance should be carried out to maintain vegetation groups of smaller sizes as far as practical.
For all existing, planted palm / cycad / ravenala bamboo / trees as well as shrubs are monitored by AA¡¦s Wildlife Hazard Consultant for usage by birds, and by AAHK. The planted area can be no more than 500 m2 for palm / cycad / ravenala / bamboo / trees and 1,000m2 for shrubs / climbers. The linear segregation for adjacent groups of palms / cycad / ravenala / bamboo / trees / shrubs should be at least 50m; however, this segregation restriction can be relaxed if the plantation is assessed as not creating significant or hazardous attraction to birds by AA¡¦s Wildlife Hazard Consultant.
Spread of tree crowns should be pruned to less than 3m for initial planting, and 6m for mature plants on the condition that the tree species does not produce fleshy fruits and that bird usage is monitored by AA¡¦s Wildlife Hazard Consultant.
• Public Lighting Design Manual (PLDM) (2nd Edition: September 2006)
As stipulated in PLDM (2nd Edition: September 2006), ¡§trees shall be planted 5m away from the lighting columns¡¨. Hence, there is a no tree zone with a 5m radius at each of the public lighting column on the HKBCF
• Areas Reserved for Future Development
There are a few areas on the HKBCF which are reserved for potential future development as shown in Figure 3.1a. Tree planting is not recommended in these areas because trees are anticipated to be removed in these areas in the near future to cater for future development.
• Areas under Shade
Areas under shade are not suitable for tree planting as the environment is not favourable for healthy development of trees. Such areas include places under the canopy cover of various building structures and under viaducts.
• Systematic Identification of Maintenance Responsibility (SIMAR) Slopes
Trees are not recommended on SIMAR slopes because the SIMAR slopes are on the embankments of viaducts. Trees may affect the sightline of road / viaduct traffic. Also, tree failure on these SIMAR slopes may pose safety hazard to road users.
• Hard-paved Areas
Tree planting is not feasible in hard-paved areas reserved for road traffic access.
• Underground Utilities and Structures
Reasonable amount of land area is reserved for accommodation of underground public utilities and under structures. Tree planting in these areas are undesirable because trees may obstruct the necessary maintenance works of underground utilities and structures.

Mitigation Measure as Extracted from Section 14.3.3.3 of the Approved EIA Report |
Implementation Detail of Mitigation Measure under the Project |
Relevant Contract(s) |
Construction Phase |
|||
G1 |
Grass-hydroseed bare soil surface and stock pile areas. |
Whenever bare soil surface and stock pile areas are expected to be left unoccupied and exposed for reasonably long periods of time, which allows the establishment of hydroseeded grass, these areas are grass-hydroseeded. For example, temporary grass-hydroseeding is applied at the bare soil surface of SIMAR slopes to protect the soil surface before shrub and groundcover planting commences. Areas of bare soil surface reserved for future development, which are expected to be unoccupied for years, are also grass-hydroseeded. |
C2, C3, C4 |
G2 |
Add planting strip and automatic irrigation system if appropriate at some portions of bridge or footbridge to screen bridge and traffic. |
This mitigation measure is implemented along some portions of viaducts, but not footbridges.
There are totally 8 nos. of pedestrian footbridges (connecting to the PCB) under the Project. They are designed with a contemporary approach with all glass balustrades resting on the light metal base. It matches with the design language used for the PCB and its transparency would allow pedestrians to appreciate the surrounding environment, including the landscape background, when they are using these footbridges. In order to keep the concept of transparency for this new footbridge design, planting on these footbridges is not recommended, but the concept of gaining greening from the transparent balustrades can still be achieved. The proposed design has been endorsed and approved in the ACABAS submission on 17 July 2012. In this connection, no planting strip to these footbridges would be incorporated (See Figure 3.7).
For viaducts, an optimal solution in terms of minimizing visual impact is developed through the use of patterned parapets to provide visual interest, and greening at the embankments (as recommended under G2) which will soften the hard structures and blend in with the at-grade soft landscape distributed amongst the road network (See Figure 3.2). Due to the abundance of at-grade soft landscape, it would be incongruous and out of keeping with the overall aesthetics of HKBCF if landscaping is repeated in the form of planters slung to all sides of the concrete viaducts which would increase the bulkiness of the viaducts. It is therefore inappropriate to add planting strip and automatic irrigation system at all portions of the bridges to be constructed under the Project, and greening along viaducts are limited to the embankments. |
C1, C2, C3, C4 |
G3 |
For HKLR, providing aesthetic design on the viaduct, tunnel portals, at-grade roads and reclamation (e.g. subtle colour tone and slim form for viaduct, aesthetic design of the bridge form and its structural elements including the parapet, soffit, columns and so on and decorative urban design elements and lightings for the HKLR; featured form of tunnel portals, roadside planting along at-grade roads and landscape berm on & planting along edge of reclamation area) to beautify the HKLR alignment |
Not applicable to the Project. This mitigation measure is applicable to HKLR, not HKBCF, hence not relevant to the Project. |
- |
G4 |
For HKBCF, providing aesthetic architectural design on the related buildings (e.g. similar materials for PCB building façade to Airport buildings, roof planting and subtle materials for other facilities buildings and so on), and the related infrastructure (e.g. parapet planting and transparent cover for elevated footbridges) to provide harmonic atmosphere of the HKBCF. |
For aesthetic architectural design on the PCB, the design of the roof has adopted a sinuous and organic form that echoes the surrounding sea and the nearby Airport as shown in Figure 3.7. The use of glass for facade and balustrade similar to Airport buildings is also shown in Figure 3.7. It optimizes the natural daylight and expansiveness of space. The design language adopted is similar to that of the current Hong Kong International Airport which can promote a unique building cluster around the airport areas to provide harmonic atmosphere of the HKBCF.
For aesthetic architectural design on other related buildings, a modern and contemporary design using simple outlines and subtle materials with light colour tones is adopted and illustrated in Figure 3.8. Such architectural design on ancillary buildings and facilities provide a harmonic atmosphere in the HKBCF. Roof planting are also proposed where feasible on related buildings as shown in the Master Landscape Plan in Figures 3.1a to 3.1c.
To harmonize the atmosphere of the HKBCF, aesthetic architectural design on infrastructures, such as roadside planting and planting along embankments of elevated roads, is incorporated into the overall design as illustrated in Figure 3.2. Design of stone swathe is also included as shown in Figure 3.9. Parapet planting is not adopted because due to the abundance of at-grade soft landscape, it would be incongruous and out of keeping with the overall aesthetics of HKBCF if landscaping is repeated in the form of parapet planters slung to the sides of the concrete viaducts which would increase the bulkiness of the viaducts. |
C1, C2, C3, C4, C8 |
G5 |
Vegetation reinstatement and upgrading to disturbed areas. |
The entire works area of the Project is on newly reclaimed land except for a small area on the existing Airport Island (see Figure 3.1a). The disturbed areas on the existing Airport Island will be reinstated to their former state with hydroseeding and planting up to the satisfaction of Airport Authority, the future maintenance agent of the reinstated areas. There are 10 nos. of deformed self-seeded trees within this small area on the existing Airport Island which need to be removed for the construction of the Project (see Appendix E). The felling of these trees would be compensated by planting 21 nos. of trees on the HKBCF to fully compensate the loss of trees in terms of aggregated girth. |
C2 |
G6 |
Maximize new tree, shrub and other vegetation planting to compensate tree felled and vegetation removed. |
In the overall landscape design of the HKBCF Island, greening opportunities have been maximized as shown in Figures 3.1a to 3.1c, with proposed tree (about 1,309 nos., including 21 nos. of compensatory trees for trees felled on existing Airport Island), shrub and groundcover planting (see Figure 3.6) covering almost all the land area without permanent hard structures where feasible. Also, roof greening (see Figures 3.1a to 3.1c and 3.3) and vertical greening (see Figure 3.4) are adopted where feasible to provide additional greening. |
C1, C2, C3, C4, C8, Future Contractor of C4 landscape works (i.e. Contractor of C9) |
G7 |
Provide planting area around peripheral of and within HKBCF and HKLR for tree screening buffer effect. |
In accordance with the restrictions in the HKIA APSL (Revision 4.0.1: October 2015), no tree is proposed in Zone 1. Tree planting are maximized on the northern, western and south-eastern periphery of as well as within the HKBCF in Zone 2 for tree screening effect as shown in Figures 3.1a to 3.1c.
The proposed no. of trees in each tree group, and the minimum segregation between adjacent tree groups strictly follow the restrictions as stipulated in the HKIA APSL (Revision 4.0.1) (see Appendix C1). All tree species proposed on the HKBCF are selected from the HKIA APSL (Revision 4.0.1: October 2015) and HKIA APSL (Revision 5.0) (see Appendix C2). |
C1, C2, C3, |
G8 |
Plant salt tolerant native tree and shrubs etc along the planter strip at affected seawall. |
Salt-tolerant native tree Thespesia populnea (ùÚ¬K¶ÀåÓ) is included in the planting proposal for tree planting along the newly reclaimed coastline.
For native shrubs, Ixora chinensis (Às²îªá) and Rhododendron simsii (¬õ§ùÃY) are included in the planting proposal along the planter strip at the seawall. |
Future Contractor of C4 landscape works (i.e. Contractor of C9) |
G9 |
Reserve of loose natural granite rocks for re-use. Provide new coastline to adopt ¡§natural-look¡¨ by means of using armour rocks in the form of natural rock materials and planting strip area accommodating screen buffer to enhance ¡§natural-look¡¨ of the new coastline. |
The new seawall is constructed with armour rocks in the form of natural rock material to create a ¡§natural-look¡¨ to the new coastline under a separate design and construction consultancy for the HKBCF reclamation works (Appendix D refers).
Planting strip along the new coastline to accommodate screen buffer and enhance the ¡§natural-look¡¨ is proposed as shown in Figures 3.1a to 3.1c and 3.2. |
C2, C3, C4,Future Contractor of C4 landscape works (i.e. Contractor of C9) |

Minimize time for construction activities during construction period. |
The progress of construction works will be closely monitored to ensure that the time for construction activities is minimized during construction period. |
C1, C2, C3, C4, C8, Future Contractor of C4 landscape works (i.e. Contractor of C9) |
V2 |
Provide screen hoarding at the portion of the project site / works areas / storage areas near VSRs who have close low-level views to the Project during HKLR & HKBCF construction. |
Not applicable to the Project. Since the entire HKBCF island is located far (>500m) from the VSRs who have low-level views to the Project, hoarding is therefore considered unnecessary. Even for the most concerned VSR31 with low-level views, who is located approximately 500m from the Project, hoarding (normally 2m in height) would have very limited screening effect. |
- |
Operation Phase |
|||
G10 |
Provide proper planting maintenance on the new planting areas to enhance the aesthetic degree. |
Planting maintenance such as watering, fertilizing, weeding, pruning and mowing etc. will begin immediately after planting. Table 4.5 and Table 4.6 show the planting maintenance principle and schedule. |
C1, C2, C3, C4, C8, Future Contractor of C4 landscape works (i.e. Contractor of C9) |
V3 |
Lighting design to minimize glare at night. Decorative road lighting to be considered during detailed design stage. |
Decorative road lighting has been considered during the detailed design stage. However, to minimize glare at night and avoid any unnecessary light spill to nearby VSRs (e.g. those on Airport Island and residents at Tung Chung and north Lantau), only minimum functional lighting will be provided for safety and all directional lighting will be facing towards, instead of away from, the HKBCF. |
