Note:      1. A correction of +3dB(A) was made to the free field measurement at monitoring station NM1A.
2. Limit level of the construction noise monitoring for school was reduced to 65 dB(A) during examination period at HKJCC on 14th June to 20th June.

In this reporting period, an examination was undertaken at the Hong Kong Juvenile Care Centre Chan Nam Cheong Memorial School from 14th June to 20th June, the Limit level of construction noise monitoring at NM2 was therefore reduced to 65 dB(A).

A summary of data and the supplementary data auditing information are shown in Appendix F. Graphical plots of the monitoring data are shown in Appendix G.

5        Ecology Monitoring

5.1      Inspection Findings

The ecological inspections were undertaken on 14 June, 21 July and 25 August 2017 by the qualified ecologist. The inspection findings are presented below.

Plants of Conservation Interest (Platycondon grandiflorus)

During the reporting period, the preventive measures, i.e erection of temporary protective fencing and sign post, were effectively implemented. No evidence suggested that the on-going construction activities within the Project Area had affected the health of Platycondon grandifloras.

However, the whole plant was observed prostrated on the ground after the severe typhoon HATO battered Hong Kong on 23 August 2017. The Hong Kong Observatory issued typhoon signal no.10 and sea level had risen above normal chart datum. It was expected that the strong wind from the typhoon and high sea water level caused adverse impact to Platycodon grandiflorus as they have low salt tolerance.

Nesting Activities of Ardeids in Breeding Season

No signs or breeding (such as courtship, nest building, brooding, juveniles etc.) of ardeids were noted within the project area during June and July. No monitoring was conducted in August as this type of monitoring is only required during the breeding season of ardeids i.e from April to July.

Roosting Activities of Ardeids in Peak Wintering Season

In accordance with the approved EM&A Manual, this monitoring parameter would not be required beyond the Peak Wintering season, i.e., from 1st November to 31st March.

Compensation for Ardeid roosting Site

To be implemented.

Compensation of Woodland Habitat 

To be implemented.

5.2      Conclusion

The implementation of the mitigation measures for the plant species of conservation interest during the reporting period provided effective protection against the construction activities in the Project Area. As aforementioned, the two groups of Platycodon grandiflorus within the fenced area were found prostrated on the ground due to severe typhoon HATO which battered Hong Kong on 23 August 2017. No sighting of ardeids or signs of any breeding/nesting activities were noted within the project area during the reporting period.

6        Landscape and Visual Monitoring

6.1      Inspection Findings

In the Reporting Period, bi-weekly landscape and visual site inspection were conducted on 9, 23 June, 14, 28 July and 11, 25 August 2017.

According to the bi-weekly site inspections, it was observed that the Contractor complied with the intended aims of the mitigation measures, for example, no construction activities were conducted or materials storage were placed outside of the working site boundary. The Contractor was advised to improve and maintain the tree protection zone.

The yellowing of green leaves (chlorosis) were observed on some trees including A0090 and A0091 on 25 August 2017. Moreover, large amount of drooping leaves with sparse foliage were also observed (as shown in Table 6). A loose wire was also observed.

11   Conclusions and Recommendations

11.1    Conclusions

The EM&A programme as recommended in the EM&A manual has been undertaken in the reporting period.

Monitoring of construction noise, ecology, landscape and visual, as well as waste management for the Project were conducted as scheduled in the reporting period. Data collected during construction noise monitoring were checked against the established Action and Limit levels and no exceedances were recorded.

For ecological monitoring, the implementation of the mitigation measures for the two groups of Platycodon grandifloras were proven to be effective against construction activities in the project area. The two groups were observed prostrated on the ground due the severe typhoon on 23 August 2017. It was suspected that the two groups of Platycodon grandifloras were affected by the strong winds and high seawater level. No sighting of ardeids or signs of any breeding/nesting activities were noted within the project area.

For landscape and visual monitoring, yellowing of green leaves (chlorosis) were observed on some trees including A0090 and A0091 on 25 August 2017. A loose wire was also observed.

11.2    Recommendations

With considerations on the construction activities and environment, the following reminders and recommendations were provided:

    All drainage facilities, erosion and sedimentation control structures (including the sedimentation tanks installed on site) should be regularly inspected and maintained in good condition, especially during the wet season.

    Noise mitigation measures, including the use of quiet plants, should be implemented in accordance with the EM&A requirement.

    Close monitoring of Platycodon grandifloras will be necessary to track their condition.

    Wires that keep the trees in place in the temporary nursery should be tightened

    Sandbags should be placed next to exposed soil near the stream channel to prevent surface runoff
