B.1 General

Any landform includes a natural drainage system and planning and development of new areas should be in harmony with this system to preserve it in its natural state as far as possible.

All new development proposals should take account of:

(a) Possible flood hazards in the whole system;
(b) Possibility of upstream development;
(c) Erosion hazards;
(d) Runoff reduction as an objective.
