SUPPLEMENTARY QUESTIONS TO NO.Z

MR EDWARD HO: Sir, in the second paragraph of the Secretary's reply to my

question, he refers to the erection of barriers to screen roads from adjacent

buildings. Would the Government please inform this Council whether, in fact,

such noise barriers have been incorporated in the design of any of the new trunk roads or flyovers and, if so, where?

And I have a second question. In the case of the Princess Margaret Road

flyover, would the Government inform this Council whether the noise level at the old flyover was so satisfactory that no improvement is considered

necessary for the new one?

SECRETARY FOR LANDS AND WORKS: Sir, in reply to the first part of the

question, the Kwun Tong By-pass Phase I includes concrete walls and parapets up to 3m high to screen noise sensitive buildings such as clinics/at

at Route 5, (Tsuen Wan to Shatin) we are putting in perspex screens to screen May Lam

Estate from noise. On the Kam Tin By-pass Stage I also we have an 1.5m

high earth mounds which bhi is noise barrier.

As to the second part of the question whether the level of noise on the old

not Princess Margaret flyover was considered satisfactory, entirely, but it did

conform with the planning standards which were adopted, that is, 70 BBA and

with a provision for excess of 10 per cent during peak traffic flow, so in

general it was considered not unsatisfactory rather than perhaps satisfactory.

KMR. SOHMEN: Sir, the Secretary mentioned that the measures adopted to reduce noise vary depending on the nature of the project and the environment. Does this mean that the results also have to vary and that acceptable, noise maximum may sometimes have to be exceeded?

SECRETARY FOR LANDS AND WORKS: Yes, certainly. Because the measures to be

adopted have to be practical.

answer

-PROF. POON: With reference to the last sentence of paragraph 2 of the

"they also include the replanning of surrounding development

to provide buffers against the traffic noise" would the Secretary please

give a real example to illustrate this point?

SECRETARY FOR LANDS AND WORKS: Sir,

1

most of the examples come from the new towns.. I can think of two in Tuen Mun

and one in Shatin and they relate to minor roads rather than the main trunk roads

1

which are not nearly so susceptible for replanning.
