The Agency may enter upon and appropriate so much of the surface or subsoil of, or airspace over, any street within the Order limits as may be required for the purposes of the authorised works and may use the surface, subsoil or airspace for those purposes or any other purpose ancillary to its undertaking.

Subject to paragraph (4), the power under paragraph (1) may be exercised in relation to a street without the Agency being required to acquire any part of the street or any easement or right in the street.

Subject to paragraph (5), any person who is an owner or occupier of land in respect of which the power of appropriation conferred by paragraph (1) is exercised without the Agency acquiring any part of that person’s interest in the land, and who suffers loss by the exercise of that power, is entitled to compensation to be determined, in the case of dispute, under Part 1 of the 1961 Act.

Compensation is not payable under paragraph (3) to any person who is an undertaker to whom section 85 (sharing of cost of necessary measures) of the 1991 Act applies in respect of measures of which the allowable costs are to be borne in accordance with that section.
