INTRODUCTION
1.1
Background
1.1.1
After public consultation on various land supply
options in 2018, the Task Force on Land Supply (Task Force) (TFLS) recommended
on 31 December 2018, among others, the Government to accord priority to
studying and resuming the 32 ha of land of Fanling Golf Course to the east of
Fan Kam Road for housing development. On 20 February 2019, the Government
announced that the eight land supply options (including the partial development
of the FGC site) recommended by the Task Force were fully endorsed.
1.1.2
The Government also announced that the Government will
develop the 32 hectares (ha) of land east of Fan Kam Road of FGC for the
purpose of housing development (with emphasis on public housing), and will
accordingly commence a detailed, technical study in the second half of 2019 to
ascertain the highest flat yield attainable in short to medium terms; assess
the scope of infrastructural works required to support such development;
identify environmental, ecological and other constraints, and formulate
mitigation measures to contain any identified impacts to within acceptable
limits; and come up with an implementation plan with timing and costs.
1.2
Purpose of this Executive
Summary
1.2.1
The Executive Summary (ES) illustrates the key
information and findings of the EIA study for the partial development of
Fanling Golf Course Site, Fanling.
2.
Project Description
2.1
General Description of the Project
2.1.1
The Potential Development Area (PDA) covers
approximately 32 ha, as shown in Figure
2.1, is bounded by Ping Kong Road to its northeast, Po Kin Road to its
north, Fan Kam Road to its northwest and west, rural settlements of Ping Kong
to its east, Tai Lung Experimental Farm and a green hillock to its southeastern
and southern ends.
2.1.2
For the purpose of technical assessment, the PDA is
divided into four areas as shown in Figure 2.2: Sub-Area 1 which is located at the northernmost
part of PDA and extended up to the edge of woodland adjacent to the Fanling Raw
Water Pumping Station; Sub-Area 2 which is bounded by the aforesaid woodland
and the access road of On Po; Sub-Area 3 which is bounded by the existing
access road of On Po in the north and the narrow edge adjacent to Tai Lung
Experimental Farm; and Sub-Area 4 which is bounded by the southern edge of
Sub-Area 3 and the site boundary of PDA.
2.1.3
Having assessed and evaluated various development
options, housing development is only proposed at Sub-Area 1 with approximate
population of 33,600. This will be further elaborated in the following
sections.
2.2
Need of Project
2.2.1
The housing shortage in Hong Kong is one of the most
pressing issues that Hong Kong is facing. Increasing the land supply for
housing development has been one of the major focuses in the Policy Addresses
in the last few years. As reported in the ¡§Hong Kong 2030+: Towards a
Planning Vision and Strategy Transcending 2030 study (Hong Kong 2030+) in
October 2021, there is an estimated housing land shortfall of 510 ¡V 680
hectares (ha) in the long run.
2.2.2
On 31 December 2018, the Task Force on Land Supply
reported a shortage of 108 ha of housing land in short term. Having
conducted extensive public engagement exercise, the Task Force
recommended that it is worthwhile to accord priority to studying and resuming
the 32 ha of land of FGC to the east of Fan Kam Road for housing development to
relieve shortage in land in short-to-medium term while balancing the needs for
sports development.
2.2.3
With the expiry of land lease for the 32 ha of land of
FGC to the east of Fan Kam Road of FGC in August 2020 and a special three-year
holding over arrangement up to August 2023, the land is expected to be reverted
to the Government in September 2023. The development to the PDA could, in
short-to-medium terms, alleviate the acute shortage of land.
2.3
Appreciation of Existing Environment
2.3.1
Taking into account of compatibility with existing
transport and infrastructure and traffic connectivity, the rural setting and
the elongated shape in the middle and southern part of the PDA, it is envisaged
that the housing development potential in Sub-Area 2 to Sub-Area 4 would be
limited.
2.3.2
Based on the selected Development Option , the
associated environmental impacts have been considered and assessed in this EIA
report.
2.3.3
The ecological value of Sub-Area 1 is relatively lower
compared to Sub-Area 2 to Sub-Area 4. In Sub-Areas 2 and 3, mammal species of
conservation importance such as Leopard Cat and Small Indian Civet were
recorded within the Sub-Areas. In Sub-Area 4, many plant/animal species
of conservation importance were found. Sub-Area 4 is also encompassing
protected species of Aquilaria sinensis and abundant endangered species under
IUCN Red List of Glyptostrobus pensilis. Therefore, Sub-Area 4 is ranked
as medium to high ecological value.
2.3.4
Apparently, the existing ecological habitats in the
vicinity, including the ecological corridor at the northern end of Sub-Area 2,
the woodland in the northern end of Sub-Area 3 near On Po, the marsh and swampy
woodland in Sub-Area 4 create a precious ecological linkage in the Sub-Areas.
Based on the selected Development Option, as only minor works in Sub-Areas 2 to
3 are recommended while no works is proposed in Sub-Area 4, the ecological
sensitive areas could be largely preserved.
2.4
Designated Projects
2.4.1
The PDA has a study area of about 32 ha. It falls
within Item 1 under Schedule 3 of the Environmental Impact Assessment Ordinance
(EIAO), i.e. "Engineering feasibility study of urban development projects
with a study area covering more than 20 ha or involving a total population of
more than 100,000" and is therefore a Designated Project (DP) requiring an
EIA report.
2.5
Project Benefits and Environmental Initiatives
Project Benefits
2.5.1
The Project intends to ease the urging demand for
housing development. The proposed development would plan for a balanced
community to optimize the use of the scarce land resources to serve the urgent
housing need as well as to provide community facilities to the neighborhood.
¡P Relieving Housing Demand ¡V The proposed housing development will
provide approximate 12,000 housing units, subject to the ratio of public rental
housing (PRH) and subsidized sale flats (SSF), which could accommodate
approximately 33,600 population, alleviating scarcity of housing supply.
¡P Creating Recreation cum Conservation Area ¡V With a concept to preserving the
precious environment, Sub-Areas 2 to 4 will be converted to form a recreation
cum conservation area for public enjoyment and relaxation. Only recreational
and ancillary facilities with minimal new structure/change to existing site
conditions would be provided in Sub-Areas 2 to 4.
¡P Community Enhancement ¡V Commercial and retail facilities will be
provided within the proposed development sites to serve the planned population
as well as the nearby community. A Public Transport Interchange (PTI),
pedestrian walkway and cycling track will be provided near Ping Kong Road which
could also serves the nearby villagers and residents.
¡P Government, Institution and Community
(G/IC) Facilities ¡V
Various educational facilities (e.g. kindergarten, etc.) a community hall as
well as social welfare facilities comprising Neighbourhood Elderly Centre
(NEC), Residential Care Home for the Elderly (RCHE) cum Day Care Unit (DCU),
Child Care Centre (CCC), Day Activity Centre (DAC), Hostel for Severely
Mentally Handicapped Persons (HSMH), Hostel for Moderately Mentally
Handicapped Persons (HMMH), Supported Hostel for Mentally Handicapped Persons
(SHOS(MH)), Integrated Vocational Rehabilitation Services Centre (VRSC) and
Hostel for Severely Physically Handicapped Persons (HSPH) have been planned in
the proposed development.
Green and
Environmental Initiatives
2.5.2
The vision of the Project is to create a sustainable,
green and liveable community provided with supporting infrastructure to cater
for future development needs. Environmental considerations are one of the
key factors in the formulating of development of the PDA. Throughout the
development formulation, appreciation has been made to the potential
environmental initiatives both to conserve existing environmental resources
and, where opportunities exist, to enhance and upgrade the environment on
various aspects. The major green and environmental initiatives that this
Project offers are summarized in below paragraphs.
2.5.3
Recently, there are increasing awareness in sustainable
development. This Project has duly considered the sustainable strategy in
respect of town planning, urban design, transportation and blue-green
infrastructure for a creation of a sustainable local community. When
formulating the development layout of the PDA, the adoption of green building
design, energy-efficient features and renewable energy technologies within the
PDA has been promoted.
2.5.4
In addition to green transport management, a
comprehensive water management system including sewerage, drainage and water
resources infrastructure has been recommended. Blue-green infrastructures
and sustainable landscape design, such as zero-irrigation, swales and rain
gardens have been considered. Besides, the use of reclaimed water for
flushing has been explored to promote the sustainable use of water.
2.5.5
The various habitats with conservation importance in
Sub-Areas 2 to 4 will be preserved under the Project as far as practicable to
maintain the local character and fringe between urban and rural areas.
Besides, podium and screen planting shall be considered to soften the built
structures in Sub-Area 1.
2.5.6
For the aspect of solid waste management, the amount of
municipal solid waste generated and disposed of can be minimised through
on-site waste management plan including local recycling of organic waste, local
recycling of glass for building blocks production and source separation of
recyclables. Also, the adoption of automatic refuse collection system
will be investigated to reduce fuel use, odour and noise of waste transport.
2.5.7
Green energy saving will also be adopted when
appropriate. Measures include encouraging the use of energy-efficient
building design and materials, promoting certification under BEAM Plus or other
equivalent accreditations, exploration of community gardens in open space and
amenity areas to promote green living, deploying energy-saving installations
such as solar hot water system, etc.
2.6
Development Programme for the Project
2.6.1
The implementation programme is summarized in Table

Summart of key findings in environmental impact
assessment (eia) study
3.1
Air Quality Impact
Key Assessment Scope
and Key Criteria
3.1.1
The potential air quality impacts associated with the
construction and operation of the Project are assessed. The air quality impact
assessment is conducted in accordance with the requirements of Annex 4 and
Annex 12 of the Technical Memorandum on Environmental Impact Assessment Process
(EIAO-TM) as well as the technical requirements given in Appendix B of the EIA
Study Brief (ESB-318/2019).
Construction Phase
3.1.2
Potential construction dust impact would be generated
from site clearance, site formation, piling works, utility works and road
improvement works. Quantitative construction dust assessment has been
conducted. The major concurrent projects include Ching Hiu Road Development,
Tai Tau Leng Development, North District Hospital Expansion, Drainage
Improvements at North District, Fanling Highway Widening, Po Shek Wu Flyover,
Lot 4076 in D.D. 91 Development, Reclaimed Water Supply to Sheung Shui and
Fanling and So Kwun Po Interchange.
3.1.3
With the implementation of mitigation measures
specified in the Air Pollution Control (Construction Dust) Regulation together
with the recommended dust suppression measures including 3m hoarding and
watering once per hour on exposed worksites and haul roads, the
predicted Total Suspended Solid (TSP), Respiratory Suspended Solid (RSP)
and Fine Suspended Solid (FSP) at representative air sensitive receivers
(ASRs) would comply with the criteria stipulated in the Air Quality Objectives
(AQOs) and EIAO-TM. The predicted concentrations for key representative
pollutants after implementation of mitigation measures are summarised
in Table 3.1.

Operation Phase
3.1.4
Key existing, planned and committed air pollution
sources during operation phase are the vehicular emission from open
sections of existing roads, proposed roads and proposed junction improvement
works within the assessment area. Cumulative air quality impact at the
representative ASRs would also be expected due to the background pollutant
concentrations, chimney emissions from North District Hospital, PTIs of the
Project, Ching Ho Estate and Tai Ping Estate within the assessment area. Key
representative air pollutants include Nitrogen Dioxide (NO2), RSP
and FSP.
3.1.5
Quantitative air quality assessment for operational
phase has been conducted, taking into account the vehicular emission impact
associated with the Project and existing road networks, industrial emission in
the vicinity of the Project and the impacts from proposed and existing PTIs and
proposed carparks. It is concluded that the predicted cumulative air quality
impacts on all ASRs would comply with the AQOs during the operational phase of
the Project. Results in Year 2029 is summarised in Table 3.2.

Noise Impact
Key Assessment Scope
and Key Criteria
3.2.1
The potential noise impacts associated with the
construction and operation of the Project are assessed. The noise
impact assessment is conducted in accordance with the requirements of Annex 5
and Annex 13 of the Technical Memorandum on Environmental Impact Assessment
Process (EIAO-TM) as well as the technical requirements given in Appendix C of
the EIA Study Brief (ESB-318/2019).
Construction
Phase
3.2.1.1 Construction noise associated with the use of Powered Mechanical
Equipment (PME) for different phases of construction has been conducted. With
the implementation of practical mitigation measures including good site
management practices, adoption of quieter construction method, use of movable
noise barrier and noise enclosure and use of quieter plant, construction noise
impacts at all of the neighbouring residential noise sensitive uses would be
controlled to acceptable levels. Minimum separation distance between schools
and critical works area during school examination period have been recommended
to mitigate potential adverse construction noise impact during examination
period.
3.2.1.2 With the recommended mitigation measures in place, construction
noise impacts on all representative Noise Sensitive Receivers would comply with
the relevant criteria.
Operation

3.2.2
Operation road traffic noise impact on the
representative existing and planned noise sensitive uses within and near the
PDA have been evaluated. To mitigate the road traffic noise impact on the
existing and planned NSRs exceeding their respective noise criteria, a
combination of noise mitigation measures has been recommended as direct and
additional mitigation measures, including i) application of low noise road
surfacing material along some sections of Project roads and other roads, ii)
provision of acoustic windows for the proposed public housing buildings and
iii) adoption of class assessment approach at the proposed school. A summary of
the predicted road traffic noise levels with mitigation measures in place is
given in Table 3.3.

3.2.3
With the implementation of mitigation measures, the
predicted traffic noise levels of the planned NSRs would comply with the
relevant noise criteria. No adverse residual impact is expected.
Fixed Noise
Source
3.2.3.1 Fixed noise source impact assessment has been conducted for all
existing and planned fixed noise sources. Noise impact from planned fixed
noise source under this Project (i.e. ventilation fans for the proposed PTI)
could be effectively mitigated by implementing noise mitigation measure at
source. With the adoption of the proposed maximum allowable Sound Power Level
(SWL), the predicted noise level at the representative NSRs would comply with
the relevant noise criteria. No adverse fixed noise is anticipated.
3.2.3.2 The PTI will be enclosed and designed to avoid direct line-of-sight
to the NSRs. The design of the PTI and the proposed maximum allowable
SWLs of the ventilation fans shall be reviewed with the final design during the
detailed design stage.
Aircraft
Noise
3.2.3.3 Aircraft noise impact on planned sensitive uses within Sub-Area 1 of
PDA has been reviewed. All departure flight paths to be in use under the
Three-runway System (3RS) operations and near to the development sites have
been assessed. The PDA is located at over 15km from the NEF 25 Contour of the
Hong Kong International Airport under the 3RS operation. Adverse aircraft noise
impact due to 3RS operation is not anticipated.
3.2.3.4 The aircraft noise impact from the operation of Shek Kong Airfield
has been reviewed. The separation between the PDA and the Shek Kong Airfield is
approximately 5.3 km. In view of the large separation between PDA and Shek Kong
Airfield, adverse aircraft noise impact due to operation of Shek Kong Airfield
is not anticipated. According to the latest information, the approach
and departure operation of aircrafts would maintain sufficient separation
distance from the PDA. Therefore, no adverse aircraft noise impact is
anticipated in the PDA.
Helicopter
Noise
3.2.3.5 Helicopter noise impact on planned sensitive uses within Sub-Area 1
of the PDA has been reviewed. According to the latest information, the flight
path of helicopters would maintain sufficient separation distance from NSRs in
Sub-Area 1 of the PDA. Therefore, no adverse helicopter noise impact is
anticipated in PDA.
3.3
Water Quality Impact
Key Assessment Scope
and Key Criteria
3.3.1
The potential water quality impacts associated with the
construction and operation phase of the Project are assessed. The
water quality impact assessment is conducted in accordance with the
requirements of Annex 6 and Annex 14 of the Technical Memorandum on
Environmental Impact Assessment Process (EIAO-TM) as well as the requirements
set out under Clause 3.4 of the EIA Study Brief (ESB-318/2019).
Appropriate mitigation measures were proposed to minimize the potential water
quality impacts.
Construction Phase
3.3.2
Water quality impacts during construction phase include
site run-off from general construction activities, accidental spillage,
groundwater from contaminated area, effects on groundwater table / hydrology /
flow regime and sewage effluent from construction workforce. The site practices
as outlined in the ProPECCPN 1/94 ¡§Construction Site Drainage¡¨ and
the ETWB TC (W) No. 5/2005 ¡§Protection of natural streams/rivers from adverse
impacts arising from construction works¡¨ are recommended to minimise the
potential water quality impacts from the construction activities. Proper site
management and good site practices are also recommended to ensure that
construction wastes and other construction-related materials would not enter
the nearby streams. Temporary sanitary facilities would be provided on construction
sites to properly collect the on-site sewage generated from the construction
workers. Regular site inspection will be conducted during construction stage to
ensure that the recommended mitigation measures are properly implemented.
3.3.3
With the implementation of the recommended mitigation
measures, the construction works for the Project would not result in
unacceptable impacts on water quality.
Operation Phase
3.3.4
During the operation phase, all the sewage and
wastewater generated from the Project will be properly collected
and discharged to the public sewerage system and conveyed to the Shek Wu
Hui Sewage Treatment Works (SWHSTW) for treatment. Discharge from the Shek Wu
Hui Sewage Treatment Works after treatment would not cause adverse water
quality impact in Deep Bay Water Control Zone.
3.3.5
A management plan stating the details of application of
agrochemicals including the type, dosage, frequency, application instructions
shall be prepared. The use and application of
fertilizers and pesticides shall follow normal practices in Leisure and
Cultural Services Department (LCSD)¡¦s prevailing code of practice and the
Pesticides Ordinance (Cap. 133). Adverse water quality impact associated with
usage of fertilizers and pesticides is therefore minimized.
3.3.6
With proper implementation of the recommended
mitigation measures, no unacceptable water quality impact would be
expected during the operation phase of the Project.
3.4
Sewerage and Sewage Treatment Implications
Key Assessment Scope and Key Criteria
3.4.1
The capacity of existing and planned sewerage
infrastructure has been reviewed based on the latest available information. The
latest development parameters of the proposed development have been utilized
for calculation.
3.4.2
New sewers were proposed to connect with the existing
trunk alongside San Wan Road. Only manageable impact to the downstream sewerage
networks is anticipated.
Construction Phase
3.4.3
The sewage generated during the construction stage from
the on-site workers will be collected in chemical toilets and disposed of
off-site. Therefore, no adverse sewerage impacts are expected from the Project
during the construction phase. As such, environmental monitoring and audit of
the sewerage system is considered not required.
Operation Phase
3.4.4
The following general mitigation measures are to be
considered in order to meet ¡¥no net increase in pollution loading¡¦ in Deep Bay:
¡P sewage collected from the site will be
conveyed to Shek Wu Hui Sewage Treatment Works (SWHSTW) and treated to a
standard suitable for recycle for non-potable use including flushing
and irrigation;
¡P Upgrading the sewerage system for discharge into
SWHSTW or providing other sewage treatment/disposal facilities to ensure that
there is sufficient capacity to cater for increased sewage effluent flows from
the developments; and
¡P Provision of suitable measures to minimize the risk of
emergency discharges of untreated sewage effluent and to ensure timely repair.
3.5
Waste Management Implications
Key Assessment Scope
and Key Criteria
3.5.1
The types of waste that would be generated during the
construction and operation phases of the Project have been identified. The
potential environmental impacts that may result from these waste materials have
been assessed in accordance with the criteria and guidelines outlined in Annex
7 and Annex 15 of the EIAO-TM, and Section 3.4.7 and Appendix F of the EIA
Study Brief.
Construction Phase
3.5.2
The main waste types to be generated during the
construction phase of the Project would include construction and demolition
(C&D) materials, chemical waste, general refuse and asbestos-containing
materials (ACMs). An estimated total of 950,000 m3 of C&D
materials are expected to be generated, of which 620,000 m3 are
inert C&D materials and 330,000 m3 are non-inert C&D
materials, a several hundred litres per month of chemical waste, around 182 kg
per day of general refuse and some ACMs to be generated during the construction
phase of the Project. Reduction measures have been recommended to minimise the
amount of materials generated by the Project by reusing C&D materials as
far as practicable before off-site disposal.
3.5.3
The inert C&D materials generated from the Project
will be reused within the Project or other concurrent projects as far as
practical. For instance, during site clearance, site formation and
infrastructure works, it is estimated that 50,000m3 of the inert
C&D materials will be suitable for reuse on-site as backfilling materials
under this Project and 570,000 m3 of inert C&D materials will be
transported to other concurrent projects and/or to Public Fill Reception
Facility (Tuen Mun Area 38 Fill Bank) for reuse. 56,000 m3 of
non-inert C&D materials (clean soil) is expected to reuse on-site. 66,000 m3
of non-inert C&D materials shall be recycled prior to off-site disposal and
208,000 m3 of non-inert C&D materials shall be disposed of at
designated landfill (NENT). Temporary stockpiling areas are also identified to
store the C&D materials for reuse under this Project. Provided that the
waste is handled, transported and disposed of using approved methods, adverse
environmental impacts would not be expected.
Operation Phase
3.5.4
The main types of waste to be generated during
the operation phase of the Project would consist of general refuse, clinical
waste and chemical waste. It is expected that the Project would generate around
34 tonnes of general refuse per day in total, about 0.002 kg of clinical waste
per person per day, and approximately 5 litres per month of chemical waste,
mainly from maintenance activities on the road networks within the PDA, and
maintenance of equipment such as cooling, electricity and paints. The general
refuse generated would be conveyed to refuse collection points before being
transported to the existing North East New Territories (NENT) Landfill outside
the PDA. Initiatives such as promoting recycling and providing recycling bins
would be employed in order to minimise the amount of general refuse to be
disposed of at landfill. Provided that the waste generated in the operation
phase is handled, transported and disposed of properly, no adverse
environmental impacts are anticipated.
3.6
Land Contamination Impact
Key Assessment Scope
and Key Criteria
3.6.1
The land contamination assessment is conducted in
accordance with the criteria and guidelines as stated in the requirements given
in Section 3.4.8 and Appendix G of the EIA Study Brief, as well as Annex 19 of
the EIAO-TM.
3.6.2
The land contamination assessment examined the potential
contaminative land uses within the PDA and their potential impacts to future
land use. The assessment on the potential land contamination was conducted
based on the findings from site appraisal, comprising of the site walkover and
review of historical aerial photographs and maps, historical spillage and
leakage records and previous site investigations (SI) undertaken at the PDA.
3.6.3
Based on the available information and size of the PDA,
149 no. of sampling locations have been proposed. Based on desktop review and
visual site inspection, the majority of the PDA has been used as a golf course,
with a small section being used as a parking lot, tennis courts, staff quarters
and private residential lots. The source of potential land contaminating
activities at the identified sites mainly relates to the historical use and
current application of fertilisers, pesticides and herbicides on the golf
course. As such, it is considered that the potential land contamination at
these sites would be localised on the turf grass areas throughout the PDA.
3.6.4
The chemicals of concern (COCs) identified with the
potential to be present at the potentially contaminated sites include the 54
COCs identified in EPD¡¦s Guidance Manual, in addition to the recommended list
of pesticides and herbicides. These COCs are readily treatable with proven
remediation techniques in local remediation experience. By implementing the
recommended remediation works, any contaminated site(s) identified within the
PDA could be cleaned up prior to construction/development.
3.6.5
The recommended remediation works would not only
minimise the health risk to the future occupants arising from the exposure of
the contaminated soil and/or groundwater, it would also provide the opportunity
to reuse the treated contaminated materials into useful materials for
backfilling, which results in minimising the amount of waste disposing into the
depleting landfill in Hong Kong and achieving a more sustainable development.
3.6.6
However, given the PDA is still in operation, SI is
unlikely to be carried out at this stage and shall only begin after the land
has been reverted to Government. Upon the land has been reverted to Government and site
clearance, a re-appraisal and a supplementary Contamination Assessment Plan
(CAP) covering the entire assessment area shall be prepared and submitted to
EPD for approval. SI and laboratory analyses shall commence after the approval
of the supplementary CAP by EPD.
3.6.7
Contamination Assessment Report (CAR) will be prepared
to present the findings of the SI works. If contaminated soil and/or groundwater
were identified, remediation should be carried out according to EPD¡¦s approved
Remediation Action Plan(s) (RAP(s)) and Remediation Report(s) (RR(s)) should be
submitted to EPD for endorsement after completion of the remediation works. No
construction works or development of site should be carried out prior to the
endorsement of RR.
3.6.8
Land contamination assessment and remediation shall be
completed prior to the development of the Project. If deemed necessary, the
contaminated sites shall be remediated before commencement of any construction
works which may disturb the ground. In all cases, contaminated soil
remediation, treatment or disposal must be managed in an environmentally sound
manner, including compliance with all relevant legislation and Government
requirements.
3.6.9
The establishment and implementation of the
supplementary CAP, CAR and/or RAP will minimise potential adverse impacts to
the environment arise from land contamination and site remediation activities.
No adverse residual impacts are anticipated from the construction and operation
of Project activities.
3.7
Ecological Impact
3.7.1
The ecological impact assessment was conducted in
accordance with the requirements set out under Annexes 8 and 16 of the TM-EIAO,
Section 3.4.9 and Appendix H of the EIA Study Brief, EIAO Guidance Notes
(6/2010, 7/2010 and 10/2010) and other relevant legislations and guidelines.
The assessment area for ecological impact assessment includes the area within
500m from the boundary of the Project Site.
3.7.2
Based on the selected Development Option, the
associated ecological impacts have been considered and assessed. The proposed
development will avoid areas of higher ecological values i.e. Sub-Areas 2 to 4
(medium or medium to high ecological values), only Sub-Area 1 with relatively
lower ecological value (low to medium) will be developed. Direct impacts to
most of the important habitats (e.g. swampy woodland with very rare Glyptostrobus
pensilis) and species of conservation importance are not expected. Besides,
the hydrological disruption due to the proposed development is not expected,
potential impacts to the hydrology of the swampy woodland are thus not likely.
With the implementation of the proposed management with the aims to protect the
important habitats and species of conservation importance in Sub-Areas 2 to 4,
the ecological conditions will be conserved and probably be enhanced.
3.7.3
As woodland and mixed woodland are identified within
Sub-Area 1, in order to minimize the potential impacts due to habitat loss
(i.e. 4.11ha of woodland and mixed woodland) and site formation, a number of
mitigation measures will be implemented. Compensation woodland planting will be
provided (~5.1 ha, larger than the loss of 4.11ha woodland and mixed woodland)
and opportunities of in advance planting will be explored. Plant species of
conservation importance recorded within Sub-Area 1 will be retained as far as
possible or transplanted. As Sub-Areas 2 to 3 will only provide recreational
facilities and ancillary facilities, and no works is proposed in Sub-Area 4, no
adverse ecological impacts are anticipated.
3.7.4
Sub-Areas 2 to 4 are intended to be zoned as
¡§Other Specified Uses¡¨ annotated ¡§Recreational cum Conservation¡¨ under Outline
Zoning Plan. Hence, Sub-Areas 2 to 4 should be
conserved and a management plan will be formulated with the aims to manage the
human activities conducted in Sub-Areas 2 to 4 and
conserve the ecologically sensitive habitats and species of conservation
importance from disturbance. With the future management plan, the potential
indirect impacts from disturbance (e.g. noise, traffic and human disturbance)
to the important habitats in Sub-Areas 2 to 4 and the
habitats in the vicinity as well as the species of conservation importance can
be further reduced. A monitoring programme will be included in the management
plan to evaluate the effectiveness of the management strategies.
3.7.5
With the implementation of mitigation measures, the
residual ecological impact from the proposed development is considered
acceptable.
3.8
Fisheries Impact
3.8.1
A study based on existing information on pond culture
fisheries resources and activities within the 500m assessment area has been
undertaken, following the criteria and guidelines for evaluating and assessing
fisheries impact as stated in Annexes 9 and 17 of the TM-EIAO.
3.8.2
The proposed development will be conducted within the
Project Site. No loss of active or inactive fish ponds are anticipated.
With the implementation of mitigation measures recommended in the Water Quality
Chapter for controlling water quality impact, the Project would not cause
any unacceptable water quality impact to fish ponds or watercourses that
provide water supply for fish ponds during construction and operation phases.
3.9
Landscape and Visual Impact
Landscape Impact
3.9.1
The Development will inevitably result in some
landscape and certain visual impacts. The works will be conducted within Golf
Course Landscape. Golf Club Building and Carpark in Golf Course are
expected to receive the most impact due to the large percentage of area to be
affected. Natural Woodland in Golf Course, Secondary Woodland in Golf
Course and Grassland will also be affected due to the large total area size. It
is not possible to fully mitigate all landscape impacts in relation to the loss
of trees and other vegetation during construction and operation phase. However,
the impacts have been reduced through minimization of construction and temporary
works area with construction control, incorporation of aesthetic landscape and
architectural design and providing more greening around the Development and
associated infrastructure works. Residual impacts to Landscape Resources
and Landscape Character Areas will provide slight beneficial to moderate
landscape impact by Year 10 when the proposed mitigation measures are in full
effect.
Tree Treatment
3.9.2
A total of 4411 nos. of trees were recorded in the PDA
and the adjacent area likely to be affected by the proposed works. 1255 nos. of
trees were identified in Sub-Area 1 and 3090 nos. were in Sub-Areas 2 to 4 of
the PDA. Regarding Sub-area 1, amongst the 1255 nos. of trees recorded
(including 70 nos. Trees of Particular Interest (TPIs)), 267 nos. are
proposed to be retained, 954 nos. of trees are proposed to be felled and 34
nos. are proposed to be transplanted. No rare and protected species are
proposed to be felled in Sub-area 1.
3.9.3
Regarding Sub-Areas 2 to 4, there are approx. 3090 nos.
of existing trees found by a broad-brush tree survey, all of the existing trees
are proposed to be retained as proposed development has no direct impact on the
concerned trees. For the adjacent areas outside the PDA, amongst 66 nos. of
existing trees recorded, 24 trees are proposed to be retained. 42 nos. of
trees, including 7 nos. of Leucaena leucocephala (undesirable species),
i.e. 35 nos. of trees are proposed to be removed due to direct conflict with
the proposed works. No rare and protected species are proposed to be felled in
adjacent areas outside PDA. To compensate the loss of 996 nos. of trees, 996
nos. of compensatory trees are proposed to be planted in Sub-Area 2, Sub-Area 3
or other suitable locations.
Visual Impact
3.9.4
Visually Sensitive Receivers (VSRs) identified in this
assessment are representatives among that individuals or groups that have a
similar sensitivity to changes in the visual and landscape environment.
Viewing Points (VPs) are the key public viewing points that will be affected by
the Project during construction or operation phase and they are selected as
representative viewpoints for photomontage.
3.9.5
Residual visual impact is expected to be reduced and
range from insubstantial to substantial adverse, of which less VSRs receive substantial adverse impacts by operation phase Year 10. With the implementation of mitigation
measures such as proposed staggered built forms and sensitive treatment and
design of external finish of the built elements, together with landscape
treatment around and within the perimeter of the site, podium gardens,
retention of mature trees and trees of high amenity value, can alleviate the
visual impacts on certain VSRs and enhance the visual quality for residents of
the proposed public housing development. To further enhance of the visual
quality, Sub-Areas 2 to 3 of the PDA will receive landscape treatment and
additional planting.
3.9.6
In conclusion, the landscape and visual impacts can be
eliminated and reduced to a certain extent with the implementation of
mitigation measures, the overall landscape and visual impacts are considered
acceptable.
3.10
Cultural Heritage Impact
3.10.1
Three Graded historic buildings, Grade 1 Fanling Lodge,
Grade 2 Clubhouse of the Hong Kong Golf Club (HKGC) and Grade 3 Half-way House
of HKGC, and six clan graves may be indirectly affected by the proposed development
option. One clan grave (G-01) will require relocation. Mitigation
recommendations for built heritage include possible green screening for the two
graded historic buildings depending on the final location, design and height of
the development and further measures, such as condition survey, monitoring,
implementing buffer zones and ensuring safe public access may be required
during the construction phase for the clan graves. The mitigation
measures are to be determined in a detailed built heritage impact assessment
during the detailed design stage. For all the graded, not-graded
historic buildings and clan graves, the overall impact is ranging from
Acceptable to Acceptable with mitigation.
3.10.2
Desk-based review indicates that existing impacts
associated with the construction and maintenance of the golf course would have
affected archaeological potential of large parts of Sub-Area 1. Three
small areas within a wooded area are identified as original landforms and are
tentative proposed for archaeological field investigation. Minor
development within Sub-Areas 2 to 4 may equally affect pockets of original
landform, but extent of development within both Sub-Area 1 and Sub-Areas 2 to 4
is yet unknown.
3.10.3
In addition, some archaeological potential exist around
the proposed drainage and minor road upgrade works to the east of Sub-Area 1 or
as yet decided works associated with minor works in Sub-Areas 2 to 4.
Depending on the details of the proposed associated and/or drainage and minor
road upgrading works to be reviewed in detailed archaeological impact
assessment at later stage (and prior to detailed design stage), an
archaeological field survey (prior to construction phase) is required if
areas outside the existing roads and drainage channels are affected, or
archaeological watching brief (during construction phase) is
required if works are within existing impact areas such as existing roads
and drainage channels. Review should be undertaken for Sub-Area 1 and Sub-Areas
2 to 4 (associated) works prior to other investigations including ground
investigation, investigation for land contamination and so on in order not to
disturb the site.
3.10.4
A detailed archaeological impact assessment including
archaeological field survey, including field scan, auger tests and test pit
excavation will be required within Sub-Area 1 and select areas within Sub-Areas
2 to 4 if development is confirmed. The archaeological survey and
archaeological impact assessment should be conducted prior to other
investigations including ground investigation, investigation for land
contamination and so on in order not to disturb the site and the archaeological
field survey.to guide the development and record archaeological information, if
any.
3.10.5
"Fanling Golf Course, The Hong Kong Golf
Club" is a New Item (N340) pending grading assessment by the Antiquities
Advisory Board (AAB). Further assessment pending to the grading of the New Item
conducted by AAB and mitigation measures, where necessary, will be proposed to
Antiquities and Monuments Office (AMO) for agreement.
3.11
Environmental Monitoring and Audit Requirements
An Environmental Monitoring and Audit (EM&A) programme will be
implemented during the construction and operation phases to regularly monitor
the environmental impacts on the neighbouring sensitive receivers. Any action
required during the construction and/or operation phases are also recommended
for implementation. EM&A requirements for air quality, noise, water
quality, sewerage and sewage treatment, waste implications, land contamination,
ecology, fisheries, landscape and visual and cultural heritage have been
recommended. Regular site inspection and audits will be conducted during
construction phase to ensure that the recommended mitigation measures are
properly implemented. The EM&A requirements are specified and detailed in
the EM&A Manual.

4.1.4
The findings of this EIA Study have predicted the
likely nature and extent of environmental impacts arisen from the construction
and operation of the Project. During the EIA process, environmental mitigation
measures have been identified for incorporation into the planning and design of
the Project, to achieve full compliance with environmental
legislation and standards during the construction and operation phases.
4.1.5
Based on the selected Development Option, the
associated environmental impacts have been considered and assessed in this EIA
report. In particular, the Development Option has the following
environmental benefits:
Avoidance of Direct Impact on Plant Species of Conservation Interest
4.1.6
Consideration of avoiding the impacts of rare/protected
plant species has been taken into account during the initial stage of the
study. In order to minimize the impacts of construction towards the existing
rare and protected plant species, the proposed public housing development will
be located at Sub-Area 1. As a result, amongst the 70 nos. of Trees of
Particular Interest (TPIs) found in Sub-Area 1 including 24 nos. mature trees
with DBHs equal to or over 1000mm and 46 nos. rare/protected plant species, 11
nos. mature trees are feasible to be preserved in-situ, 2 nos. of mature trees
are to be transplanted to nearby receptor site within the PDA and 11 nos.
mature trees are to be removed due to proximity with the proposed building
layout. Amongst 32 nos. rare/protected plant species, all of them are proposed
to be transplanted to nearby suitable receptor site.
4.1.7
In addition, there are 395 nos. of TPIs found in
Sub-Areas 2 to 4 including 41 nos. mature trees with DBHs equal to or over
1000mm and 80 nos. rare/protected species including Aquilaria sinensis
(43 nos.) and Glyptostrobus pensilis (30 nos.), Lagerstroemia indica
(2 nos.) and L. speciosa (5 nos.).
Avoidance of encroachment onto Recognised Sites of Conservation
Importance
4.1.8
All the recognized sites of conservation importance,
including Sites of Special Scientific Interest (SSSI), Country Park,
Conservation Areas, and Long Valley Nature Park have been avoided and will not
be encroached by any developments under the Project.
Avoidance of Important Habitats
4.1.9
Important habitats including Fung Shui Wood and the
egretries outside the PDA would not be impacted. Within the PDA, the habitat
types with medium or above ecological values (e.g. swampy woodland and marsh)
have been avoided.
Avoidance of Direct Impacts on Clan Graves
4.1.10
With the exception of a single grave, development and
direct impact on clan graves has been avoided within the PDA boundary.
