14. Discounting for temporary written permission

Where any chargeable consent given in relation to a development or a subdivision of any land is a temporary written permission, the amount of land betterment charge payable under the Act in respect of the chargeable consent is ascertained by —

first, working out the amount of land betterment charge according to Division 1 or 2;

then, ascertaining the percentage specified in the Sixth Schedule corresponding to the range within which falls the specified period (rounded up to the nearest month or year, as the case may be) that the planning permission or conservation permission is granted; and

finally, calculating the sum that is the percentage ascertained under paragraph (b) of the amount worked out under paragraph (a), rounded up to the nearest dollar.
