Remarks:
[A] SHD Topside Development includes residential blocks, commercial / retail area, public transport interchange and kindergarten. Attachment 1A shows the proposed development for podium level.
[B] SHD Topside Development includes residential blocks, commercial / retail area, public transport interchange, school(s) and kindergartens. Attachment 1A shows the proposed development for podium level.
Notes:
[1] Tower number of SHD Topside Development.
[2] R – Residential Premises, E – Educational Institutions (school), C – Country Parks.
[3] NAP equals to Noise Assessment Points. Figure 4.7 and Figure 4.9 show the location of NSRs for fixed noise and rail noise assessment.
[4] The industrial operations at the existing SHD without decking. Attachment 1B shows the proposed stage for SHO and SHD Replanning Works.
[5] These planned assessment points will face directly to the sea, and thus they would not be affected by the IFs.
[6] In accordance with Annex 13 of the EIAO–TM, country parks are considered to be a NSR. However, the EIAO–TM and IND–TM do not provide a specific noise limits for Country Parks.
[7] Refer to the scenario description above for its respective phasing on the definition of urban area.
[8] According to IND–TM, “directly affected” means that the NSR is at such a location that noise generated by the IF is readily noticeable at the NSR and is a dominant feature of the noise climate of the NSR; “indirectly affected” means that the NSR is at such
a location that noise generated by the IF, whilst noticeable at the NSR, is not a dominant feature of the noise climate of the NSR; “not affected” means that the NSR is at such a location that noise generated by the IF is not noticeable at the NSR.
[9] The corresponding ASRs of the NSRs are determined based on the best available information and is for indicative assessment only. The Noise Control Authority shall determine noise impact from concerned noise sources on the basis of prevailing legislation
and practices being in force, and the ASRs determined in this report should not bind the Authority when enforcing the NCO based on the contemporary conditions. The ASR would be reviewed as necessary based on the contemporary conditions/situations
such as adjoining land uses, influencing factors or the latest SHD Topside Development layout.
