As soon after the applicant has filed all documents and supplied all information required by such Officer, but not later than 30 days from the date a completed application is filed, the Officer shall file such application and all other documents with the Clerk of the Planning Board, who shall place the application on the agenda for the next meeting of the Planning Board. The application shall be reviewed at such meeting, and the Chairman shall set a date for a public hearing, notice of which shall be: posted; and published at least two times in the official newspaper, the first publication of which shall be at least 10 days prior to the date set for the hearing; and mailed to owners of property lying within 1,500 feet of the proposed site and to such other owners of property in the vicinity of the proposed site as the Chairman of the Board shall determine. It shall be sufficient if the determination of ownership is based on the current assessment role and assessment map, but the failure to notify all such owners shall not render defective any action of the Planning Board or the Board of Appeals. The date of such public hearing shall be within 40 days from the date on which the completed application was filed in the Clerk of the Planning Board.
