Table 7 : Assumptions on Roadspace, Open Space and School Facility Provision

(a) Roadspace: Roadspace is assumed to be one sixth (16.7%) of DSA except for podium development in which no internal roads are required.

(b) Open Space: 1m2 of LOS per person when there are more than 500 persons.

(c) School  facilities


Provision assumptions:

[Table Summary]


Facility Site Area Threshold for provision
First Primary School (30 classrooms) 6 200m2 6 700 persons
Second Primary School (30 classrooms) 6 200m2 20 100 persons
Third Primary School (30 classrooms) 6 200m2 33 500 persons
First Secondary School 6 950m2 7 500 persons
Second Secondary School 6 950m2 22 500 persons
Third Secondary School 6 950m2 37 500 persons

Notes: (i) Full population thresholds: 13 400 for 30-classrooms primary schools and 15 000 for secondary schools; based on 7.3% and 9.0% of the total population aged 6 to 11 and 12 to 18 respectively. The percentage shares of student age group are derived from population age structure and projected age structure of transients in mid-1999 from Census and Statistics Department.

  (ii) Where a population generates sufficient pupils to take up over half the places in a school, a school is allowed for within the DSA of that development. The population thresholds for the first 30-classroom primary and secondary school are therefore 6 700 and 7 500 respectively, and for the second, 20 100 and 22 500, and so on.


Population thresholds for school site area increments:

7 500 1PS +1SS 13 150
