(1)Where the area of chargeable land in respect of which, apart from this section, a sum is payable by any person by way of a drainage charge consists of or includes a fraction of an acre, then for the purpose of calculating that sum the fraction shall be disregarded if it is less than one-half and treated as one acre in any other case.
(2)The sum payable by way of a drainage charge in respect of chargeable land consisting of commercial woodlands shall be calculated as if the area of the land were one-fifth of its actual area; and in the application of subsection (1) of this section to such chargeable land the area ascertained in pursuance of this subsection (and not the area of which it is one-fifth) shall be treated as the area mentioned in that subsection.
