Site Selection of HKBCF Major Concerns

Original options presented in public workship in Oct 2008

Notes: Owing to insufficient space provided for construction of HKBCF in Option 4 and location of HKBCF being too close to Tung Chung New Town in Option 6, these two options were not discussed in local resident meetings from Jan to Feb 2009.
