“Where it is proved to the satisfaction of the confirming authority . . . . that equally convenient accommodation can be provided . . . . at some place other than within the area or the immediate vicinity . . . . and it is also proved to the satisfaction of such authority that the required accommodation has been or is about to be forthwith provided.” The confirming authority may be satisfied with such provision, and for this purpose the local authority may make use of any lands belonging to them, or purchase any that are suitable (42 & 43 Vic. c. 63, s. 4). This part of the Act has again been amended in the year 1882 by 45 & 46 Vic. c. 54, which in section 3 enacts as follows: “. . . . and where any such improvement scheme comprises an area situate elsewhere than in the metropolis or the City of London, it shall, if the confirming authority so require (but it shall not otherwise be obligatory on the local authority so to frame their scheme), provide for the accommodation of such number of those persons of the working class displaced in the area with respect to which the scheme is proposed in suitable dwellings to be erected in such place or places either within or without the limits of the same area as the said authority, on a report made by the officer conducting the local enquiry, may require . . . .” Having thus far given the _modus operandi_ under which the Act has to be enforced, it is necessary to see what are some of the town surveyor’s duties in connection therewith. First, there are the “maps, particulars, and estimates” which have to be prepared, and these involve-- (_a._) Accurate surveys of the area; (_b._) A reference of all the properties included: (_c._) A census of the population of the area; (_d._) A valuation of all the properties; (_e._) A plan of the proposed new streets, &c. (_f._) An estimate of the cost of the whole work. In addition to this it is necessary for the local authority to “impose suitable conditions and restrictions as to the elevation, size, and design of the houses and the extent of the accommodation to be afforded thereby, and to make due provision for the maintenance of proper sanitary arrangements,” and this naturally involves detailed drawings of the buildings to be erected. In the same clause (38 & 39 Vic. c. 36, s. 9) it is stated that the local authority may engage with any society, &c., to carry the whole or any part of the scheme into effect, but “the local authority shall not themselves, without the express approval of the confirming authority, undertake the rebuilding of the houses or the execution of any part of the scheme, except that they may take down any or all of the buildings upon the area, and clear the whole or any part thereof, and may lay out, form, pave, sewer, and complete” all the necessary streets, &c., which shall thenceforth be public streets repairable by the inhabitants at large.
