As requested by the study brief in section 3.4.7
Visual Illustration, this section reviews the potential visibility of the
proposal.
The main components of this
section of the report involve an analysis of the following:
·
The existing site and surrounds;
·
The proposed modifications to the
development;
·
The potential visibility of the
retro-fit works.
7.1.1
The existing site
The existing site is located on
the western side of Lamma Island as shown in Figure 7.1. The site
is currently used as a power station and is characterised by large scale
industrial infrastructure.
Figure 7.1 Location
of the Proposed Retrofit
Figure 7.1 shows
the existing site from the air. It
is clear that the site is dominated by the existing power station. The site is
surrounded by water to the east, south and west, with some shrub land and small
buildings to the north.
7.1.2
The proposed modifications
The following works will be
undertaken:
- The removal of two existing tanks
approximately 7.6m high and 7.5 metres in diameter;
- The removal of associated pipes and
infrastructure;
- The installation of two new Flue Gas Desulphurisation
(FGD) units. Unit 4 FGD is approximately 28m(L) x 27m(W) x 45m(H) and the
Unit 5 FGD approximately [26m (L) x 21m(W) x 45m(H) + 40m(L) x 7m(W) x
45m(H)]. Both are adjacent to an existing 210m high chimney;
- FGD Switchgear and electrical equipment
building of approximately 22m(L) x 15m(W) x 12m(H) is to be installed in
an open area between Switchgear road and Main road.
The layout of the proposed new
facilities within the existing power station is shown in Figures 1.1 and 1.2.
Figure 7.2 shows
the general location of the proposed FGD units, (the existing tanks are red in
colour). The location is surrounded by heavy industrial infrastructure
associated with electricity generation.

Proposed Colour Scheme
Figure 7.3 is a 3D
model showing the location and size of the proposed retrofit. This shows the
scale of the retrofit works which will be relatively small with respect to the
existing facilities on the site.

7.1.3 Proposed Colour
Scheme
The absorber and ductwork would be enclosed by aluminium cladding that will
complement the existing surrounding industrial facility. The new FGD Switchgear
and Electrical Equipment Building will be finished in light
grey colours that will complement with existing buildings.
7.1.4
Impact on the Surrounding Landscape
The proposed retrofit will have
no impact on the surrounding landscape as all the works are contained within
the boundary of the existing power station.
7.2
Visibility of the Proposed Works
The potential visibility of the
proposal was examined from two locations, from Hung Shing Yeh Beach (VP 1) and
from the walking trail between Kat Tsai Wan and Tit Sha Long (VP2). These
locations are shown below in Figure 7.4. The approximate distance to the site
of the proposed retrofit works is about 1100 m from VP1 and 1700 m from VP2.

ViewPoints towards Existing Site
Figure 7.5 View
from VP1 towards Existing Site
Figure 7.5 above is a view towards the existing
facility taken from VP 1, Hung Shing Yeh Beach. The retrofit facilities may be visible
from this location, however, given the industrial surroundings within which the
new facilities will be located, the visibility of the new facilities will be
low.
Figure 7.6 shows
the view towards the existing site when viewed from the south-east, VP2. This
gives an indication of the scale of the existing facilities (the chimney stacks
are 210 metres tall).
Figure 7.6 View
from VP2 towards Existing Site
The proposed works will be
located adjacent to the middle chimney stack. The retrofit works will be hidden
from view by the existing infrastructure and from this viewpoint they will not
be visible.
The location of the retrofit
within the existing infrastructure will be hidden from external views to the
site. Therefore the visibility of the works will be insignificant.
The proposed retrofit works will
not have any negative impact on the surrounding landscape, and will have a very
low visibility for the following reasons:
·
The location for the proposed
retrofit works is within a large existing industrial facility;
·
There will be no impacts on the
surrounding landscape area;
·
The new infrastructure will be
finished to complement the existing industrial surroundings;
The relatively small scale of the
retrofit works within the existing facility means the works will have a low
visibility.
