(1)A local planning authority whose area consists of or includes the whole or any part of a National Park may make arrangements for securing the provision in their area (whether by the authority or by other persons)—
(a)of accommodation, meals and refreshments (including intoxicating liquor);
(b)of camping sites; and
(c)of parking places and means of access thereto and egress therefrom,
and may for the purposes of such arrangements erect such buildings and carry out such work as may appear to them to be necessary or expedient:
Provided that a local planning authority shall not under this section provide accommodation, meals or refreshments except in so far as it appears to them that the facilities therefor are inadequate or unsatisfactory, either generally or as respects any description of accommodation, meals or refreshments, as the case may be.
(2)The functions of a local planning authority under the last foregoing subsection shall be exercisable either on land in the Park or on land in the neighbourhood thereof; and where the local planning authority is a joint planning board, land in the neighbourhood of the Park which is in the area of any of the constituent authorities shall be treated for the purposes of the last foregoing subsection as in the area of the joint planning board, whether or not it is in that area.
(3)The foregoing provisions of this section shall not authorise an authority, on land in which any other person has an interest, without his consent to do anything which apart from this section would be actionable at his suit by virtue of that interest.
(4)A local planning authority may acquire land compulsorily for the purpose of any of their functions under this section.
