SCHEMATIC STUDY OF TSZ SHAN DEVELOPMENT AT TING KOK, TAI PO
VII.Environmental Impact Assessment
The Environmental Impact Assessment (EIA) Report for the project has predicted that the construction work of this project may cause environmental and residual impacts to the adjacent areas and the general public. So the project would conform to environmental legislation and imply with proposed construction and operation phase mitigation measure to minimize these impacts.
Population and environmentally sensitive areas would include villages located north of Tung Tsz Road, area nearby Access Road and road users of Access Road and Tung Tsz Road.
The environmental issues below have been appraised in this EIA report:
- Tree felling plan
- Construction noise impact
- Construction air quality impact
- Water quality impact
- Waste management
A. Tree felling plan
There is no specific trees must be reserved on site based on the record of the Register of Old and Valuable Trees. Trees will be felled for the purpose of widening the access road. These trees are located at both sides of the Tung Tsz Road and Access road to widen the road to 8m and 12m respectively. The details of the widening work will be mention in the part of Transportation Design.
B. Construction noise impact
Noise during the construction works would mainly be related to the construction works and the usage of powered mechanical equipment (PME) for construction activities, erection or dismantling of formwork and hammering works.All the construction activities would process under the noise control guidelines and standards mentioned by The Noise Control Ordinance (NCO) and alsoEnvironmental Impact Assessment Ordinance (EIAO).
Daytime construction noise between work time periods (i.e. 7a.m.-7p.m.) on workdays is restrained by the EIAO-TM. EIAO-TM specifies the construction noise limits to be 75dB.
In order to reduce noise impacts, activities would be carried out in phases, which could avail to reduce the number of PME needed to be sit on-site and the noisy works will be performed during the less noise sensitive time periods (1000-1600). Besides, baffle/noise screens will be provided to noisy machines and temporary noise barriers and enclosure will be set up around the construction site.
C. Construction air quality impact
The factor which will affect the air quality from the Project would include dust nuisance from demolition and gaseous emissions from the construction equipment. All the construction activities would process under the guidelines for air quality assessment mentioned by The Air Pollution Control Ordinance (APCO) and Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM).
The EIAO-TM state that the hourly total suspended particulates (TSP) level at susceptive receivers should not over 500 gm-3 TSP for different construction activities.
To minimize the construction air quality impacts, improvements from construction sites have been provided such as watering site area frequently, covering material properly during transportation and the site area should be kept clean.
D. Water quality impact
The Water Pollution Control Ordinance is the main authority to set outs the legislation to protect and control water quality in Hong Kong. Potential sources of water quality impact will due to the construction site runoff and drainage, unrestrained release of ruins and wastes such as packaging, construction refuses and sewage effluent produced generated on the work areas.
To minimize construction impacts on water quality, the excavation activities would be prosecuted in dry condition, and control measures should be provied to the runoff and drainage from the site areas to lessen putting up run-off. Correct works area management and proper housekeeping measures are necessary to guaranteed that construction wastes and materials would not go into the River or fish ponds at Shuen Wan. It was also recommended that compulsory site audits be attempted to inspect the construction works at all site areas.
E. Waste management
There are different types of refuses that will be to be produced during the construction period. The wastes which would be generated from the Project include construction and demolition (C&D) materials, chemical refuse and general waste.
To minimize the impacts, some good site practices and waste reduction measures are provided: Any unused chemicals or those with excess useful content shall be recycled, planning and stocking construction materials should be considered carefully to avoid unnecessary formation of waste, covering all materials during heavy rainfall, reducing land intake of stockpile areas as far as possible and general waste should be put in enclosed storage packet and isolate from C&D material.
For the landscape engineering for the site, some architectural facilities will be included on site.
A. Lotus Pond
The Lotus Pond with size of 60m x 16m x 1.5m will be located in front of the Guan Yin Temple.
Lotus is chosen since it is a one of the most complex and eminent Buddhist symbols of genuineness and enlightenment. From the muddy depths it grows into a magnificent and odorous flower. Moreover, people can come into view from ignorance, become pure, and developed into acquaintance. Also, the lotus is a cosmic flower, representative of the supramundane. Most of the Buddha and Bodhisattva figures are on lotus seat of state.
The garden will be allocated to the north of the Guan Yin Statue and the lecture hall. It will provide a serene and peaceful setting to enjoy a wide dissimilarity showing of plants.
For the garden in the north of the Guan Yin Statue, there are 8 lamps and 3 tables in the garden for the visitors to take a rest or chatting. Also, the garden is surrounded by natural timber dcor and there is clipped box plating inside the garden.
For the garden in the north of the lecture hall, there are also 8 lamps inside the garden. And there are two long tables for the visitors to take a rest or chatting. Besides, there is a sand stone pavement and a pool inside the garden. And the garden is surrounded by natural timber dcor.
Apart from the above facilities, many plants will be cultivated around the site. Such as Palm, Bauhinia, Azalea, Magnolia, Bamboo, etc.
