“Every person who shall intend to erect any new building shall give notice to the urban authority of such intention by writing delivered to them at their office or at the office of their surveyor, and shall at the same time leave or cause to be left at the said office detail plans and sections of every floor of such intended new building, drawn to a scale of not less than 1 inch to every 8 feet, showing the position, form and dimensions of the several parts of such building, and of the watercloset, earth closet, privy, cesspool, ashpit, well, and all other appurtenances; and together with such plans and sections he shall leave or cause to be left at the office of the urban authority, or of their surveyor, a description of the materials of which the building is proposed to be constructed, of the intended mode of drainage, and means of water supply. “Such person shall at the same time leave or cause to be left at the office of the urban authority, or of their surveyor, a block plan drawn to a scale of not less than 1 inch to every 44 feet, and shall show the position of the buildings and appurtenances of the properties immediately adjoining, the width and level of the street in front, and of the street, if any, at the rear of such building, the level of the lowest floor of such building, and of any yard or ground belonging thereto. “Such person shall likewise show on such plan the intended lines of drainage of such building, and the intended size, depth and inclination of each drain; and the details of the arrangement proposed to be adopted for the ventilation of the drains.” With reference to the deposit of plans as required by the above byelaw, the following suggestions as to the best manner of effecting this may be of some use: (1.) The town surveyor should see that the person, or his agent, intending to carry out the work, deposits tracings of the proposed street or building signed by himself, so that there should be no after dispute as to what really has been deposited; these tracings should be on good paper properly inked in and coloured so as to be indelible. In some towns it is the practice for original plans to be deposited temporarily with the surveyor, who is expected to have them traced and then returned to the owner, but this not only tends to the possibility of dispute as to the correctness of the tracings, but it also takes up a large amount of the surveyor’s time, or of such other officer as may have charge of this branch of the duties. In order to insure that the plans deposited shall not be afterwards claimed by the person making the deposit, it might be well to add these words to the clause of the byelaws which I have quoted: “All such plans and sections so left at the office of the urban authority or of their surveyor, shall remain the property of the urban authority.”
