The custodian of records shall establish a fixed place where all public notices and agenda will be posted. This notice board should be in a place that is accessible to members of the public at times when the City Hall is open and (if possible) should be lighted and available for public inspection even at times when the City Hall is closed. A window or glass door at the entrance to the City Hall may be used as the notice board, provided such notices are placed in such a fashion that they can be read by persons on the outside of the City Hall.
