20. (1) Whenever any street or square or part thereof which is not vested in any local authority is required for executing any development scheme, the Authority shall cause to be affixed in a conspicuous place in or near such street, square or part thereof, a notice signed by the Chief Executive Officer stating the purpose for which the street, square or part thereof is required, and declaring that the Authority will, on or after a date to be specified in the notice, take over charge of such street, square or part thereof from the owner thereof; and shall simultaneously send a copy of such notice to the owner of such street, square or part thereof. (2) After considering and deciding objections, if any, received in writing before the date specified in the notice under sub-section (1), the Authority may take over charge of such street, square or part thereof from the owner thereof; and the same shall thereupon vest in the Authority. (3) When the Authority closes or alters any street or square or part thereof which has vested in it under sub-section (2), it shall pay to the previous owner compensation at such rate and in such manner as may be prescribed for the loss of his rights therein. (4) If the closing or alteration of any such street or square or part thereof causes damage or substantial inconvenience to owners of property adjacent thereto, or to residents in the neighbourhood, the Authority shall forthwith provide some other reasonable means of access for the use of persons who were entitled to use such street, square, or part thereof as a means of access to any property or place; and if the provision of such means of access does not sufficiently compensate any such owner or resident for such damage or inconvenience, shall also pay him reasonable compensation in money.
