Significant for LR3 (Buildings within Declared Monument), LR4 (Open Space within Declared Monument), and LCA1 (Historical Landscape); and
	Slight for LR1 (Transport Route), and LCA4 (Residential/ Commercial/ Urban Landscape) for LCA 3 (Watercourse Landscape), LR1 (Channelized Watercourse), LR12 (Village Area) and LR16 (Rural Built/Open Storage Area) and LR18 (Roads)

The remaining six landscape resources LR2 (Commercial/ Residential/ Institutional Building Area), LR5 (Public Park/ Recreational Area), LR6 (Hong Kong Zoological & botanical Garden), LR7 (Vegetated Slope), LR8 (Natural Woodland on Hillside) and LR 9 (Temple Area) are not impacted by the Project and neither are the remaining five landscape character areas LCA2 (Park Landscape), LCA3 (Medium/High-rise Commercial Urban Landscape), LCA5 (Central Civic Administration Landscape), LCA6 (Natural Hillside Landscape) and LCA7 (Major Transport Corridor).

Upon mitigation, the significance of residual, adverse impact is:

	Moderate for LR3 (Buildings within Declared Monument), LR4 (Open Space within Declared Monument), and LCA1 (Historical Landscape); and
	Slight for LR1 (Transport Route) and LCA4 (Residential/ Commercial/ Urban Landscape).

Impacts on Trees
Amongst the eleven trees found on site, four dead/damaged trees (T1, T2, T3 and T4) and one healthy tree (T10) will be removed.  The rest of the trees will be retained.  The size, tree form, performance, and landscape and amenity value of T10, in comparison with the large and robust wall trees in other parts of the city, are relatively low.  Due to site and technical constraints, in situ preservation and transplanting cannot be recommended.  Mitigation measures to protect the retained trees and compensation of the removal of T10 will be implemented.  With the implementation of the mitigation measures, impacts on the trees are considered acceptable

Landscape Impact – Operation Phase
During operation and before mitigation, landscape impacts remain the same as for operation, with the exception of:

	LR1 (Transport Route) which is reduced from slight to insignificant;
	LR3 (Buildings within Declared Monument) which is reduced from significant to moderate;
	LR4 (Open Space within Declared Monument) which is reduced from insignificant to slightly beneficial;
	LCA1 (Historical Landscape) which is reduced from significant to moderate; and
	LCA4 (Residential/ Commercial/ Urban Landscape) which is reduced from slight to insignificant.

Upon mitigation, the significance of residual, adverse impact is: 

Slight for LCA1 (Historical Landscape), LR3 (Buildings within Declared Monument); and

Insignificant for LR1 (Transport Route), LR2 (Commercial/ Residential/ Institutional Building Area), LR5 (Public Park/ Recreational Area), LR6 (Hong Kong Zoological & botanical Garden), LR7 (Vegetated Slope), LR8 (Natural Woodland on Hillside), LR9 (Temple Area), LCA2 (LCSD Theme Park Landscape), LCA3 (Medium/High-rise Commercial Urban Landscape), LCA4 (Residential/ Commercial/ Urban Landscape), LCA5 (Central Civic Administration Landscape), LCA6 (Natural Hillside Landscape), and LCA7 (Major Transport Corridor).

The impact on LR4 (Open Space within Declared Monument) will be further enhanced such that it is significantly beneficial both at day 1 and year 10 of operation.

Visual Impact – Construction Phase

At construction phase, the unmitigated impacts identified are:

	Significant for six VSRs (Central/ Mid-Levels Escalator above Hollywood Road; Medium/ High Level Commercial/Residential Building(s) above Hollywood Road; Street Level at The Centrium on Arbuthnot Road; Medium/High Rise Level Residential Building(s) on Chancery Lane; Street Level at Hollywood Road/Pottinger Street Junction; and Medium/High Level Residential Buildings on Old Bailey Street);
	Moderate for two VSRs (Street Level at Old Bailey Street/ Chancery Lane Junction; and Medium/High Level Residential Buildings in Mid-levels (Grand Panorama Building)); and
	Slight for three VSRs (Street Level at Staunton Street/ Peel Street Junction; Medium/High Level Commercial Building(s) (IFC Building); and Open/Park Area off Old Bailey Street).

Following the implementation of the proposed visual mitigation measures, despite the measures alleviating the visual impacts slightly, they are not influential enough to reduce the significance of the visual impacts and all classifications remain the same.

Visual Impact – Operation Phase
At operation phase, the unmitigated impacts identified are:

	Significant for three VSRs (Street Level at The Centrium on Arbuthnot Road; Medium/High Rise Level Residential Building(s) on Chancery Lane; and Medium/High Level Residential Buildings on Old Bailey Street);
	Moderate for five VSRs (Medium/ High Level Commercial/Residential Building(s) above Hollywood Road; Central/ Mid-Levels Escalator above Hollywood Road; Street Level at Old Bailey Street/ Chancery Lane Junction; Street Level at Hollywood Road/Pottinger Street Junction; and Medium/High Level Residential Buildings in Mid-levels (Grand Panorama Building)); and
	Slight for three VSRs (Street Level at Staunton Street/ Peel Street Junction; Medium/High Level Commercial Building(s) (IFC Building); and Open/Park Area off Old Bailey Street).

Upon mitigation at Day 1, the residual impacts are:

	Moderate for four VSRs (Central/ Mid-Levels Escalator above Hollywood Road; Street Level at The Centrium on Arbuthnot Road; Medium/High Rise Level Residential Building(s) on Chancery Lane; and Medium/High Level Residential Buildings on Old Bailey Street);
	Slight for six VSRs (Street Level at Old Bailey Street/ Chancery Lane Junction ; Medium/ High Level Commercial/Residential Building(s) above Hollywood Road; Street Level at Hollywood Road/Pottinger Street Junction; Street Level at Staunton Street/ Peel Street Junction; Medium/High Level Commercial Building(s) (IFC Building); and Medium/High Level Residential Buildings in Mid-levels (Grand Panorama Building)); and
	Insignificant for two VSR (Open/Park Area off Old Bailey Street); and Medium/High level Commercial Buildings (QRC Building)

Upon mitigation at Year 10, all residual impacts remain the same as Day 1.

Different façade treatments have been considered for the new building, taking into account their potential to pose glare impact.  A fully glazed façade was rejected partially due to the potential to pose glare impact and a polished aluminium metal panel façade was also rejected over the potential for glare impact.  A cast aluminium unitized façade system has been considered suitable for the new building, having done studies of existing site material textures and scales, such as porous masonry, traditional brick and granite wall constructions.  The versatility of aluminium in terms of texture, malleability, light weight, lifecycle and general aesthetic makes it the preferred material for the distinctive integration of new construction within the historical heritage compound.  As opposed to a material like stainless steel where the finish is usually highly reflective, the materiality of the cast aluminium units will have a distinctive roughness and texture.  Together with their materiality, the unit blocks also serve to break down the façade surface adding to the reduction of reflectivity and glare, especially important during the daytime.  

At night, light emitted from the building will be partially screened by the façade units, creating a balance between being able to express the life of the buildings within while also being able to reduce light pollution.  The most open area within the new buildings at night is the public restaurant which is located on the north end of Old Bailey Wing and away from the row of residential buildings directly to the south.  All lights within the CPS will be turned to night time mode (dimmed) after 11pm. 

With respect to external façade lighting, the historic buildings would not traditionally have been lit artificially since electric lighting was a new technology in the early 20th century and its application would have been devoted first to those areas previously lit by other means, that is, interiors.  Even by the time of the site’s decommissioning, the extent of external lighting was limited to wayfinding and the illumination of spaces, not the illumination of buildings.  Such light that fell upon the exteriors of buildings was incidental.  Any new external lighting scheme would therefore seek to replicate this condition and be deliberately understated and currently there are no plans to illuminate the buildings within the Site with external lighting. 

Given the choice of façade treatment and Site lighting considerations, the glare impact from the Project is considered to be acceptable.
