31.—(1) The undertaker may fell or lop any tree or shrub near any part of the authorised development, or cut back its roots, if it reasonably believes it to be necessary to do so to prevent the tree or shrub from—
(a)obstructing or interfering with the construction, maintenance or operation of the authorised development or any apparatus used in connection with the authorised development; or
(b)constituting a danger to persons using the authorised development.
(2) In carrying out any activity authorised by paragraph (1), the undertaker must do no unnecessary damage to any tree or shrub and must pay compensation to any person for any loss or damage arising from such activity.
(3) Any dispute as to a person's entitlement to compensation under paragraph (2), or as to the amount of compensation, is to be determined under Part 1 of the 1961 Act.
(4) The undertaker may not pursuant to paragraph (1) fell or lop a tree within the extent of the publicly maintainable highway without the consent of the highway authority.
(5) Save in the case of emergency, the undertaker must not less than fourteen days before entering any land pursuant to paragraph (1) serve notice of the intended entry on the owners and occupiers and, where the land is highway maintainable at the public expense, on the highway authority.
32.—(1) Subject to the following provisions of this article, the undertaker may at its own expense carry out such protective works to any building lying within the Order limits as the undertaker considers necessary or expedient.
(2) Protective works may be carried out—
(a)at any time before or during the carrying out in the vicinity of the building of any part of the authorised development; or
(b)after the completion of that part of the authorised development in the vicinity of the building at any time up to the end of the period of 5 years beginning with the start of commercial use.
(3) For the purpose of determining how the functions under this article are to be exercised the undertaker may enter and survey any building falling within paragraph (1) and any land within its curtilage.
(4) For the purpose of carrying out protective works under this article to a building the undertaker may (subject to paragraphs (5) and (6))—
(a)enter the building and any land within its curtilage; and
(b)where the works cannot be carried out reasonably conveniently without entering land which is adjacent to the building but outside its curtilage, enter the adjacent land (but not any building erected on it).
(5) Before exercising—
(a)a right under paragraph (1) to carry out protective works to a building;
(b)a right under paragraph (3) to enter a building and land within its curtilage;
(c)a right under paragraph (4)(a) to enter a building and land within its curtilage; or
(d)a right under paragraph (4)(b) to enter land,
the undertaker must, except in the case of emergency, serve on the owners and occupiers of the building or land not less than fourteen days' notice of its intention to exercise that right and, in a case falling within sub-paragraph (a) or (c), specifying the protective works proposed to be carried out.
(6) Where a notice is served under paragraph (5)(a), (5)(c) or (5)(d), the owner or occupier of the building or land concerned may, by serving a counter-notice within the period of ten days beginning with the day on which the notice was served, require the question whether it is necessary or expedient to carry out the protective works or to enter the building or land to be referred to arbitration under article 41 (arbitration).
(7) The undertaker must compensate the owners and occupiers of any building or land in relation to which rights under this article have been exercised for any loss or damage arising to them by reason of the exercise of those rights.
(8) Where—
(a)protective works are carried out under this article to a building; and
(b)within the period of 5 years beginning with the day on which the part of the authorised development carried out in the vicinity of the building is first in commercial use it appears that the protective works are inadequate to protect the building against damage caused by the carrying out or use of that part of the authorised development,
the undertaker must compensate the owners and occupiers of the building for any loss or damage sustained by them.
(9) Nothing in this article relieves the undertaker from any liability to pay compensation under section 10(2) of the 1965 Act (compensation for injurious affection).
(10) Any compensation payable under paragraph (7) or (8) is to be determined, in case of dispute, under Part 1 of the 1961 Act (determination of questions of disputed compensation).
(11) In this article “protective works” in relation to a building means—
(a)underpinning, strengthening and any other works the purpose of which is to prevent damage which may be caused to the building by the carrying out, maintenance or use of the authorised development; and
(b)any works the purpose of which is to remedy any damage which has been caused to the building by the carrying out, maintenance or use of the authorised development.
