Project Designs Meeting the Environmental Performance Requirements in EIA Ordinance Technical Memorandum

projects with a total estimated cost of HK$ 151 billion covering 16 km of roads, 47 km of railways, 216 ha of development projects, 164 ha airport Decommissioning - have gone through the statutory EIA process to meet relevant environmental criteria.

Population Protected

About 570,000 people along and at the vicinity of railway lines, road alignments, reclamation sites, decommissioning site of airport, etc. protected or with impacts minimised.

Problems Avoided or Environmentally Friendly Designs Adopted to Protect the Environment

  • electrified railway system of West Rail (I) to avoid air pollution caused by road traffic equivalent to 2,500 bus trip/day.
  • avoiding adverse impacts to 4 active fishponds of about 2 ha.
  • providing 11km road side noise barriers to protect 85,000 people.
  • adopting buffers ranging from 29 to 67m wide to protect 14ha areas for noise attenuation.
  • using podium structures at residential development to segregate noise sources and receivers to protect 12,000 people.
  • avoiding adverse noise impact by adopting 13.5 km viaduct with 7 km noise barriers and, 8.4 km rock tunnel, 2.3 km surface alignment, 3.0 km cut and cover tunnel, and 3.1 km enclosure structure at grade along West Rail (I).
  • adopting multi-plenum system with restricted maximum train speed of 130 km/hr to reduce noise pollution from West Rail (I) to protect population along the railway line.
  • compensating ecological losses in drainage channel projects by providing:
  • 6.5 ha grasscrete, 3.0 ha marshcrete, 13.5 ha reinstating fish ponds, 12 ha recreated wetland, replanting 1,500 trees along 4 km of river channels.
  • providing 31,000m2 rubble mound seawall to protect the soft and gorgonian corals growth at Lamma during the construction of power plant.
  • shifting from existing coal-fired units to gas-fired units of HEC's Lamma Power Station to improve local air quality.
  • providing silt curtain enclosing the immediate grabbing area to avoid spillage of mudwater to surrounding water.
