2.1.2. The area
for the proposed widening and deepening of channels would be excavated. Upon completion of excavation works,
construction of proposed rectangular channels would be carried out on site by
fixing of reinforcement bars and concreting works.
2.1.3.
The general location plan
is shown in Figure
2.1. The site specific
works for the four villages are described below and shown in Figures 2.2 to 2.5B:
Sung Shan New
Village
2.1.4.
It
is proposed to carry out upgrading works along 610m of the existing stream. The
cross section of the proposed rectangular channel with width ranging from 7.5m to 8.0m varies in
height (3m to 5m) along the stream to suit the
existing site constraints by optimizing the hydraulic capacity but minimizing
the land resumptions. Pedestrian crossings will be re-provided along the
proposed works. The proposed works at Sung Shan New Village are shown in Figure 2.2.
Tai Wo
2.1.5.
It
is proposed to provide a 290m long of rectangular channel with 1m wide of
various height at Tai Wo to suit the existing site constraints by optimizing
the hydraulic capacity but minimizing the land resumptions and discharging to
the existing channel at the west. The proposed channel height ranges from 1.5m
to 3.1m. The proposed works at Tai Wo are
shown in Figure 2.3.
Lin Fa Tei
2.1.6.
A
150m long and 2m wide rectangular channel of height of approximately 1.7m is
proposed to intercept part of the surface runoff from hillside and connect to
the upstream of Shui Tsan Tin stream which will then be
upgraded to a proposed rectangular channel with width ranging from 2.4m to 4.8m
wide with total length of approximately 780m along the original alignment to
suit the existing site constraints by optimizing the hydraulic capacity but
minimizing the land resumptions. The proposed channel height at the south of
Lin Fa Tei is approximately 3.7m. The 240m long 2m
wide rectangular channel of various height downstream of Lin Fa Tei channel is proposed to be deepened along original
alignment. Part of the flow will be diverted to the proposed 1650mm dia. storm
drain underneath Kam Sheung Road. Pedestrian and vehicular crossings will be
re-provided along the proposed works. The proposed works at Lin Fa Tei are shown in Figures
2.4A and 2.4B.
Ha Che
2.1.7.
Approximately
600m of the existing stream is proposed to be upgraded to a rectangular channel
of various width and depth along the original alignment to suit the existing
site constraints by optimizing the hydraulic capacity but minimizing the land
resumptions. The proposed channel width is ranging from 3m to 6.5m, while the
proposed channel height is ranging from 1.8m to 3.1m. For the bottleneck at Fan
Kam Road, it will be improved by additional twin 1500mm dia. drains located to
the south of the existing twin 1500mm dia. drains. A portion of stream of about
170m long (adjacent to Fu Hing Garden) will be upgraded to 3.5 to 4.5m wide
rectangular channel of various height. Pedestrian and vehicular crossings will
be re-provided along the proposed works. The proposed works at Ha Che are shown in Figures 2.5A and 2.5B.

2.2
Need
for the Project
2.2.1.
Currently,
the four villages are susceptible to flooding in the existing drainage system.
Under the DMP Review Study commissioned by DSD in 2008, it was identified that
some areas in Yuen Long District could not meet the required flood protection
level according to the latest land use changes and future developments. This
includes taking into account of various factors, including sedimentation at the
downstream main channels, mangrove growth at river estuaries, updated extreme
sea level statistics at Tsim Bei Tsui
and projected Climate Change impacts in the hydraulic analysis. To account for
the severity and extent of possible flooding, the DMP Review Study proposed
drainage improvement works in the Yuen Long District. DSD carried out a further
review on the proposed works under the Project and it was considered feasible
to improve the existing drainage condition for the four villages in Yuen Long.
The proposed drainage improvement works aim to alleviate the flooding spots in
the villages.
2.2.2.
In
addition to improving the flood situation in the villages, the proposed
landscaping works of the channels will revitalize the channels in terms of
visual and landscape treatment for public enjoyment and blending into the environment.
2.3
Scenarios
With and Without the Project
2.3.1.
Areas
of Sung Shan New Village, Tai Wo, Lin Fa Tei and Ha
Che will continue to expose the adverse risk of flooding.
2.3.2.
After
the improvement works, area of Sung Shan New Village, Tai Wo, Lin Fa Tei and Ha Che will provide a protection level of 10 years
and the flood situation will be significantly improved.
2.4
Consideration of
Alternative Design and Layout
2.4.1. Detailed
review of the DMP Review Study, site conditions and public aspirations have
been carried out. Alternatives of the original design scheme are discussed
below:
Drainage Improvement Works at Sung Shan New Village
Option 1
2.4.2.
To
improve the drainage condition, the existing stream is proposed to be upgraded
to a consistent 5m wide trapezoidal channel before connecting to the existing
nullah along Tai Shu Ha Road. The proposed alignment will be realigned to
reduce the extent of meander at midstream with land resumption. Natural bedding
will be constructed at the trapezoidal channel for provisioning of habitat in
the existing stream. Pedestrian crossings will be re-provided along the proposed works. (Drawing No. 5124336-GLP-OE-1031 refers).
Option 2
2.4.3.
It
is proposed to carry out upgrading works along the existing stream. In order to optimize the hydraulic capacity,
the cross sections will vary along the proposed channel to suit the existing
site constraints as well as providing natural bedding and intermediate openings
for natural bedding in various sections for provisioning of habitat in the
existing stream. This option would also minimize land resumptions by avoiding
encroaching into private land lots. Pedestrian crossings will be re-provided
along the proposed works (Drawing No. 5124336-GLP-OE-1032 refers).
Option 3
2.4.4.
It
is proposed to carry out upgrading works along 610m of the existing stream. The
cross section of the proposed rectangular channel with width ranging from 7.5m
to 8.0m varies in height (3m to 5m) along the stream to suit the existing site
constraints by optimizing the hydraulic capacity but minimizing the land
resumptions. Green channel with natural bedding is proposed as far as possible
to maintain the naturalness of the existing stream. Pedestrian crossings will
be re-provided along the proposed works (Drawing No. 5124336/GLP/OE/1033 refers).
Drainage Improvement Works at Tai Wo
Option 1
2.4.5.
A
new 1350mm dia. pipe is proposed along the existing low-lying area at the south
of Tai Wo, connecting to the existing channel in the west (Drawing
No. 5124336/GLP/OE/1041
refers). The proposed underground drains would minimise the disturbance to the
existing land, visual impact and habitats.
Option 2
2.4.6.
Considering
the limited government land, trapezoidal channel design will not be considered.
In order to optimise the drainage capacity but minimizing the land resumptions,
it is proposed to provide a 1m (W) x 1.5m (H) open rectangular channel along
the existing low-lying area at the southwest corner of Tai Wo connecting to the
engineering channel at the west, which facilitates collection of surface
runoff. A 900mm covered channel is proposed to collect the
runoff within Tai Wo Village and divert the flow to proposed rectangular
channel (Drawing No. 5124336/GLP/OE/1042
refers).
2.4.7.
It
is proposed to provide a 290m long of rectangular channel with 1m wide of
various height at Tai Wo and discharging to the existing channel at the west.
Due to land matters, the construction of proposed 900mm covered channel proposed in Option
2 requires obtaining HAD’s consent, hence it has been removed from this option.
The proposed channel height ranges from 1.5m to 3.1m. (Drawing No. 5124336/GLP/OE/1043 refers).
Drainage Improvement Works at Lin Fa Tei
Option 1
2.4.8.
A
2m wide rectangular channel is proposed to intercept the runoff from upstream
of Lin Fa Tei stream and convey into Shui Tsan Tin stream which will then be upgraded to a 4m wide
trapezoidal channel with local straightening at bend. The proposed alignment
will be realigned to reduce the extent of meander at midstream with land
resumption. Portion of the Shui Tsan Tin stream will
need to be in the form of rectangular shape due to the limited space between
village houses. Natural bedding will be provided to various sections along the
proposed channel. Pedestrian and vehicular crossings will be re-provided along
the proposed works (Drawing Nos. 5124336/GLP/OE/1051 and 5124336/GLP/OE/1052 refer).
Option 2
2.4.9.
A
2m wide rectangular channel is proposed to intercept the runoff from upstream
of Lin Fa Tei stream and convey into Shui Tsan Tin stream which will then be upgraded to trapezoidal
channel or rectangular channel along the original alignment. The existing Lin
Fa Tei stream is proposed to be upgraded to 1m wide
rectangular channel along the original alignment to increase the drainage
capacity. Natural bedding will be provided to various sections along the
proposed channel. Pedestrian and vehicular crossings will be re-provided along
the proposed works (Drawing Nos. 5124336/GLP/OE/1055 and 5124336/GLP/OE/1056 refer).
Option 3
2.4.10.
Shui
Tsan Tin stream will be upgraded to rectangular channel
along the original alignment as far as possible. Pedestrian and vehicular
crossings will be re-provided along the proposed works. It is proposed to be a
2m wide rectangular intercepting channel, connecting to the upstream of Shui Tsan Tin stream to cut off part of surface runoff from the
hill. At the downstream approximately 2m wide rectangular channel across the
entrance of Lin Fa Tei village is proposed to be
deepened along the original alignment, with part of the flow diverted to the
proposed twin 1050mm dia. storm drains underneath Kam Sheung Road which will be
connected to existing engineered nullah to increase the drainage capacity.
Natural bedding will be provided to various sections along the proposed channel
(Drawing Nos. 5124336/GLP/OE/1057
and 5124336/GLP/OE/1058
refer).
Option 4
2.4.11.
A
2m wide rectangular channel of height of approximately 1.7m is proposed to
intercept part of the surface runoff from hillside and connect to the upstream
of Shui Tsan Tin stream which will then be upgraded
to a proposed rectangular channel with width ranging from 2.4m to 4.8m wide
with total length of approximately 930m along the original alignment. The
proposed channel height at the south of Lin Fa Tei is
approximately 3.7m. Green channel with natural bedding is proposed to maintain
the naturalness of the existing stream. The 240m long 2m wide rectangular
channel of various height downstream of Lin Fa Tei
channel is proposed to be deepened along original alignment. Part of the flow
will be diverted to the proposed 1650mm dia. storm drain underneath Kam Sheung
Road. Pedestrian and vehicular crossings will be re-provided along the proposed
works (Drawing Nos. 5124336/GLP/OE/1059
and 5124336/GLP/OE/1060
refer).
Drainage Improvement Works at Ha Che
Option 1
2.4.12.
To
improve the drainage capacity, it is recommended to upgrade the existing stream
adjacent to the Fan Kam Road to a 6m wide rectangular channel at the upper
stream and a 8m wide trapezoidal channel at
mid-stream. Due to being close to the existing buildings, a portion of stream
of about 200m long (adjacent to Fu Hing Garden) will be upgraded to a twin cell
box culvert with 2.5m (H) ×2.5m (W) each. Natural bedding will be provided in
the areas of Sections A and B Drawing No. 5124336/GLP/OE/1071. Natural bedding would not be required within proposed box culvert as
shown in Section C of Drawing No. 5124336/GLP/OE/1072. Existing
bottlenecks at crossings at the Fan Kam Road and at access road to Shui Kan Shek will be upgraded to a twin cell box culvert with 2.5m
(H) ×2.5m (W) each. Pedestrian and vehicular crossings will be re-provided
along the proposed works (Drawing Nos. 5124336/GLP/OE/1071 and 5124336/GLP/OE/1072 refer).
Option 2
2.4.13.
The
existing stream is proposed to be upgraded to a 3m (W) x 2m (H) rectangular channel
along the original alignment to suit the existing site constraints by
optimizing the hydraulic capacity but minimizing the land resumptions. For
underground drainage pipes, it would be impracticable to provide natural
bedding due to risk of blockage and flooding. For the bottleneck at Fan Kam
Road, addition of two 1500mm dia. drains will be proposed by pipe jacking
method. A portion of stream of about 200m long (adjacent to Fu Hing Garden)
will be upgraded to 4.5m (W) x 3m (H) rectangular channel. Pedestrian and vehicular crossings will be
re-provided along the proposed works (Drawing Nos. 5124336/GLP/OE/1073 and 5124336/GLP/OE/1074 refer).
Option 3
2.4.14.
The
existing stream is proposed to be upgraded to a 3m (W) x 2m (H) rectangular
channel along the original alignment to suit the existing site constraints by
optimizing the hydraulic capacity but minimizing the land resumptions. For the
section upstream close to Shui Kan Shek, it is
proposed to construct a new 2m (W) x 1.5m (H) rectangular channel and maintain
the existing channel due to space constraint in the area. For the other
existing bottleneck at access road to Shui Kan Shek,
two 1200mm dia. pipes will be provided to improve the cross-section area. For
another bottleneck at Fan Kam Road, addition of two 1500mm dia. drains will be
proposed by pipe jacking method. A portion of stream of about 200m long
(adjacent to Fu Hing Garden) will be upgraded to 4.5m (W) x 3m (H) rectangular
channel. Pedestrian and vehicular crossings will be re-provided along the
proposed works (Drawing Nos. 5124336/GLP/OE/1075
and 5124336/GLP/OE/1076
refer).
Option 4
2.4.15.
By
optimizing the hydraulic capacity but minimizing the land resumptions, approximately
600m of the existing stream is proposed to be upgraded to a rectangular channel
of various width and depth along the original alignment to suit the existing
site constraints. The proposed channel width is ranging from 3m to 6.5m, while
the proposed channel height is ranging from 1.8m to 3.1m. For the bottleneck at
Fan Kam Road, it will be improved by additional twin 1500mm dia. drains located
to the south of the existing twin 1500mm dia. drains. A portion of stream of
about 170m long (adjacent to Fu Hing Garden) will be upgraded to 3.5 to 4.5m
wide rectangular channel of various height. Green channel with natural bedding
is proposed to maintain the naturalness of the existing stream. Pedestrian and
vehicular crossings will be re-provided along the proposed works. (Drawing
Nos. 5124336/GLP/OE/1077 and 5124336/GLP/OE/1078 refer).
Preferred Options of Drainage Improvement Works
2.4.16.
Considering the options of
drainage improvement works as described in para. 2.4.2 to 2.4.15 and the
corresponding drawings, the preferred option is presented as follows:
Sung Shan New Village
2.4.17.
The
trapezoidal channel design considered in Option 1 would have a larger footprint
of the proposed channel, which would encroach into a number of private land
lots and clearance of the existing structures is inevitably required. The
trapezoidal channel design will likely arose strong
public objection. Full width opening at channel bed in Option 3 is more
preferable over the provisions of intermediate openings in Option 2 in
environmental point of view. Thus, the preferred option is Option 3. It is
proposed to provide a 7.5m – 8.0m (W) x 3m – 5m (H) rectangular sections with
vertical wall to optimize the use of government land by minimizing land
resumption to suit the existing site constraints while meeting the requirements
for hydraulic performance. The Aquilaria Sinensis (seedling) in Sung Shan New Village will be protected
and retained during construction. Green channel with natural bedding will be
provided along the proposed channel as far as possible. The preferred option is
presented in Figure 2.2.
Tai Wo
2.4.18.
Considering
the limited government land, trapezoidal channel design will not be considered.
The drainage capacity of the rectangular channel design in Option 3 is more
preferable as compared to Option 2. Thus, the preferred option is Option 3. It
is proposed to provide a 1m (W) x 1.5m – 3.1m (H)
open rectangular channel along the sloping ground at the southwest corner of
Tai Wo connecting to the engineering channel at the west. The width of the
channel was limited to avoid land resumption, hence to
fulfil the requirements of hydraulic performance. Green channel with natural
bedding will be provided along the proposed channel. The width and depth of the
proposed channel also limits the maintenance works to be carried within the
channel. The preferred option is presented in Figure 2.3.
Lin Fa Tei
2.4.19.
The
trapezoidal channel design considered in Options 1 and 2 would have a larger
footprint of the proposed channel, which would encroach into a number of
private land lots and clearance of the existing structures is inevitably
required. The trapezoidal channel design will likely arose
strong public objection. Full width opening at channel bed in Option 4 is more
preferable over the provisions of intermediate openings in Options 2 and 3 in
environmental point of view. Thus, the preferred option is Option 4. Shui Tsan Tin stream (the southern proposed works) will be
upgraded to a rectangular channel along the original alignment as far as
possible as green channel with natural bedding to maintain the naturalness of
the existing stream. It is proposed to upgrade the existing rectangular
intercepting channel, connecting to the upstream of Shui Tsan
Tin stream, to a proposed rectangular channel ranging from 2.4m to 4.8m wide
and 3.7m high along the original alignment to cut off part of surface runoff
from the hill which will then be upgraded. At the northern proposed works, an
approximately 240m long 2m wide rectangular concrete channel adjacent to the
entrance of Lin Fa Tei village is proposed to be
deepened along the original alignment with natural bedding, with part of the
flow diverted to the proposed 1650mm dia. storm drains underneath Kam Sheung
Road which will be connected to existing engineered nullah to increase the
drainage capacity. Green channel with natural bedding or natural bedding will
be provided at various sections along the proposed channel subject to the
hydraulic performance at particular locations. Pedestrian and vehicular
crossings will be re-provided along the proposed works. The preferred option is
presented in Figures 2.4A
and 2.4B.
Ha Che
2.4.20.
The
trapezoidal channel design considered in Option 1 would have a larger footprint
of the proposed channel, which would encroach into a number of private land
lots and clearance of the existing structures is inevitably required. The
trapezoidal channel design will likely arose strong
public objection. Full width opening at channel bed in Option 4 is more
preferable over the provisions of intermediate openings in Options 2 and 3 in
environmental point of view. Thus, the preferred option is Option 4. It is
proposed to upgrade the existing stream to a 3m – 6.5m (W) x 1.8m – 3.1m (H)
rectangular channel along the original alignment to suit the existing site
constraints by optimizing the hydraulic capacity but minimizing the land
resumptions. For the bottleneck at Fan Kam Road, it will be improved by
additional twin 1500mm dia. drains located to the south of the existing twin
1500mm dia. drains by pipe jacking method. A portion of stream of about 170m
long (adjacent to Fu Hing Garden) will be upgraded to 3.5m to 4.5m wide
rectangular channel of various height. Pedestrian and vehicular crossings will
be re-provided along the proposed works. Green channel with
natural bedding will be provided along the proposed channel. The preferred
option is presented in Figures
2.5A and 2.5B.
2.5
Consideration of Alternative Construction
Methods and Sequences of Work
Proposed
Underground Drainage Pipes
2.5.1. The proposed
works for underground drainage pipes would be implemented by open cut method as
far as practicable, due to its cost effectiveness in the improvement in
proposed drainage works. The proposed works would be carried out on a
section-by-section basis to minimize period of nuisance to the nearby sensitive
receivers during construction.
2.5.2. A
proposed drainage section will be located across Fan Kam Road in Ha Che. In
order to minimise traffic impact on the existing roads, trenchless method is
proposed for pipe installation. The proposed drainage section located
underneath Kam Sheung Road in Lin Fa Tei would be
constructed by open trench method.
2.5.3.
Table 2‑2 provides
the comparisons on environmental benefits and dis-benefits of open-cut and
trenchless method.
Table 2‑2 Environmental Benefits and Dis-Benefits
of Alternative Construction Methods
|
Options |
Environmental Benefits |
Environmental Dis-Benefits |
|
Open-Cut Method |
· Faster construction progress and hence the period of environmental disturbance is reduced. |
· Construction nuisances including dust and noise will affect all sensitive receivers along entire works alignment. |
|
Trenchless Method |
· Excavation is only required at launching and receiving pit locations. Hence localized construction nuisances are limited to the sensitive receivers near the working pits only. · Comparatively less excavated materials will be generated. |
· Longer period of environmental disturbance due to slow construction progress. |
2.5.4. For
open-cut method, temporary traffic management will be carried out on a
section-by-section basis to minimize period of nuisance to the village
traffic. Upon the completion of utility
survey and inspection pits to ensure no existing utilities would clash with the
proposed works, ground excavation will take place between the time periods 7am
and 7pm. No construction noise permit would be required. For excavation greater
than 1.2m, sheetpiles with struts and wales will be
constructed as temporary support adjacent to the slope. Underground pipes would
be laid after the completion of pipe bedding and then backfilled with soil.
2.5.5. For
trenchless method, the jacking pit and receiving pit would be constructed for
the trenchless pipe sections. The pipes would be carried out by segmental pipe
jacking method. After the completion of tunnel between the two pits, the
proposed underground pipe would be laid.
2.6
Project Implementation
Programme
2.6.1. The
proposed drainage improvement works in four villages are planned to commence in
2022 and completion in 2025. The tentative construction programme is provided
in the Table 2‑3 below.
The proposed rectangular channels at the 4 villages will be constructed during
dry seasons. The proposed pipe works at Lin Fa Tei
will be constructed during wet seasons as the construction of new drainage
pipes will not be constrained by any existing flow.
