on habitats of ecological importance in the vicinity of the Project, 2m high
solid dull green site barrier fences shall be erected around all active works
areas. As the Works programme under above EPs were
still under preparation work and the barrier
fences erection was still progressing in the Reporting Month, 2m high solid
dull green site barrier fences will be checked once in place. The Hoarding Plan
of the above EPs refer to EP submission.
Implementation Status of Air Quality and Noise Mitigation Measures
10.5
According
to the EIA Report and the Updated EM&A Manual, the Air quality and Noise
mitigation measures detailed in the documents are recommended to be implemented
during the construction phase. Air quality and Noise mitigation measures
implemented by the contractors were closely monitored to prevent water
pollution, especially during dry season. An updated summary of the
Environmental Mitigation Implementation Schedule is provided in Appendix Q. Specific Air quality and
Noise mitigation measures for major construction works in the reporting month
are presented in Table 10.4.

Ecological Mitigation Measures – Creation of Long Valley
Nature Park (LVNP)
10.9
From
the findings of EIA Report, the area of Long Valley has been assessed as of
high to very high ecological value and is the largest contiguous area of
freshwater wetland habitats in Hong Kong. To safeguard the ecological value of
Long Valley, about 37 hectares of land in Long Valley has been proposed to
develop into Long Valley Nature Park (LVNP) for conserving and enhancing the
ecologically important environment as well as for compensation of the wetland loss
due to the NDA development.
10.10
LVNP is developed according to approved
Habitat Creation and Management Plan (HCMP) submitted under EP-468/2013/A. The
HCMP provides a framework and specifications for development and management of
the LVNP and guides the development to maintain and enhance the 37ha of
low-lying wetland habitats.
10.11
Regarding
to the design, the zoning of land use in the LVNP is intended to maintain the
existing mosaic pattern of wet and dry agriculture, while controlling the activities
that could potentially disturb target habitats and species. The LVNP will
divide into three broad zones of land use as below:
•
Biodiversity
Zone of about 21 hectares largely designated for biodiversity conservation
through cultivation of specified crops and habitat management.
•
Agricultural
Zone of about 11 hectares designated for commercially focuses crop production
and eco-friendly agricultural practice for farming.
•
Visitor
Zone of about 5 hectares designed to accommodate visitors as well as storage
and other facilities and for educational purposes.
10.12
The
construction of the LVNP started in late 2019 and is expected to be completed
in 2023. During construction period, the progress of construction and wetland
enhancement works are under observation by different stakeholders including
AFCD and green groups. Close communication between AFCD and CEDD are conducted
to exchange views on conservation, restoration and management of habitats as
well as on the planning and design of the park. Also, advices from green
groups, Hong Kong Bird Watching Society (HKBWS) and The Conservancy Association
(CA), are taken on habitat management of Long Valley and potential effects on
habitat and wildlife of each individual work conducted in Long Valley. Regular
meeting are held monthly to share the progress of LVNP with different
stakeholders, including CEDD, AFCD, CA, HKBWS, Contractor, ET, IEC and farmers.
However, meeting in March was canceled due to pandemic outbreak.
10.13
Proposals
on wetland creation and restoration, dry agricultural land creation, pond
creation, water treatment wetland and design of irrigation channel are
submitted by the Contractor to achieve the objectives stated in HCMP and
accepted by the Engineer with consent from AFCD before implementation. The Contractor
will consult with the stakeholders for recommendations and suggestions on
mitigation measures to minimise the environmental
impacts arising from construction works. The progress of works will be arranged
to minimise impacts to avifauna and maintain the
habitat for avifauna. The photographic records of site activities in LVNP are
presented in Table 10.5.
