(e) A request that the territory included within such boundaries be formed into a district for the improvement and development of the harbor.
Each signer of the petition shall be a registered voter, resident and freeholder within the proposed district.
The petition shall be published for a least two weeks preceding the hearing thereon in a newspaper of general circulation printed in the proposed district, if there is such a newspaper so printed. If not, publication shall be so made in a newspaper published in the county.
