“Where any street within any urban district (not being a highway repairable by the inhabitants at large) or the carriageway, footway, or any other part of such street is not sewered, levelled, paved, metalled, flagged, channelled and made good, or is not lighted to the satisfaction of the urban authority, such authority may, by notice addressed to the respective owners or occupiers of the premises fronting, adjoining or abutting on such parts thereof as may require to be sewered, levelled, paved, metalled, flagged or channelled, or to be lighted, require them to sewer, level, pave, metal, flag, channel or make good, or to provide proper means for lighting the same within a time to be specified in such notice. “Before giving such notice the urban authority shall cause plans and sections of any structural works intended to be executed under this section, and an estimate of the probable cost thereof, to be made under the direction of their surveyor, such plans and sections to be on a scale of not less than one inch for eighty-eight feet for a horizontal plan, and on a scale of not less than one inch for ten feet for a vertical section, and, in the case of a sewer, showing the depth of such sewer below the surface of the ground: such plans, sections and estimate shall be deposited in the office of the urban authority, and shall be open at all reasonable hours for the inspection of all persons interested therein during the time specified in such notice; and a reference to such plans and sections in such notice shall be sufficient without requiring any copy of such plans and sections to be annexed to such notice. If such notice is not complied with, the urban authority may, if they think fit, execute the works mentioned or referred to therein; and may recover in a summary manner the expenses incurred by them in so doing from the owners in default, according to the frontage of their respective premises, and in such proportion as is settled by the surveyor of the urban authority, or (in case of dispute) by arbitration in manner provided by this Act; or the urban authority may by order declare the expenses so incurred to be private improvement expenses. “The same proceedings may be taken and the same powers may be exercised in respect of any street or road of which a part is or may be a public footpath or repairable by the inhabitants at large, as fully as if the whole of such street or road was a highway not repairable by the inhabitants at large” (38 & 39 Vic. c. 55, s. 150). One has only to look at the number of footnotes that follow this clause both in “Glenn” and “Fitzgerald” to see that it requires some considerable interpretation. I propose in this chapter to call attention to some of its engineering discrepancies and to point out the duties of the town surveyor in connection with its enforcement.
