Bridgton residents in Tuesday’s election defeated half of the ordinances proposed for their town, including a hotly debated mooring ordinance.

Of the six items on the referendum ballot, the mooring ordinance was the most divisive, with residents holding conflicting views on whether the town needed to hire a part-time harbor master and create a system for regulating the number and location of moorings.

The proposal was defeated, with 403 in favor and 530 opposed.

Voters approved a proposal to change the ordinance governing site plan review, 463 to 405, and another one that adopts an international building code for commercial buildings, 502-388.

They also backed a proposal to broaden an existing ordinance to control disorderly behavior in residences, 613 to 286. The measure empowers selectmen to impose fines on the owners of properties where three or more public disturbances occur within 60 days.

They rejected two proposed changes to the shoreland zoning ordinance.
