The local planning authority may at any time prepare a revision of a local development document.
The authority must prepare a revision of a local development document—
if the Secretary of State directs them to do so, and
in accordance with such timetable as he directs.
This Part applies to the revision of a local development document as it applies to the preparation of the document.
Subsection (5) applies if any part of the area of the local planning authority is an area to which an enterprise zone scheme relates.
As soon as practicable after the occurrence of a relevant event—
the authority must review every local development document in the light of the enterprise zone scheme;
if they think that any modifications of the document are required in consequence of the scheme they must prepare a revised document containing the modifications.
The following are relevant events—
the making of an order under paragraph 5 of Schedule 32 to the Local Government, Planning and Land Act 1980 (c. 65) (designation of enterprise zone);
the giving of notification under paragraph 11(1) of that Schedule (approval of modification of enterprise zone scheme).
References to an enterprise zone and an enterprise zone scheme must be construed in accordance with that Act.
