Designation of streets as having special engineering difficulties
15.—(1) The criteria for designating a street as having special engineering difficulties under section 63 are —
(a)in the case of a street with which an engineering structure is associated, that its fundamental integrity and safety is dependent upon special measures being taken in the planning and execution of street works in the relevant part of the street in order to avoid serious failure of the structure concerned; or
(b)in the case of any other street, that there is a specific engineering feature identified as fundamental to the structure and integrity of the street as a whole requiring special measures to be taken in the planning and execution of street works in order to avoid serious failure of the street as a whole.
(2) The procedure for making or withdrawing such a designation is set out in the Schedule.
(3) The information to be made available by the street authority in respect of each street for the time being designated by them as having special engineering difficulties must include —
(a)the date of designation;
(b)particulars of the street in sufficient detail to enable it to be identified;
(c)the features which justify the designation; and
(d)particulars of the authority or undertaker with an interest in the street.
