Bridgewater residents are going to have to start keeping noise at a respectable level. The town has approved a noise by-law by a 4-3 vote. The document includes maximum decibel limits of 75 decibels between 10pm and 6am. It increases to 90 decibels during the day. Meanwhile, the town is in the middle of reviewing all of its by-laws to see which ones are necessary and which ones can be scrapped. Mayor David Walker says it doesn't make sense to add another by-law in the middle of the process.Walker voted against the by-law along with councillors Michael Graves and Jennifer McDonald. The by-law won't take effect right away. There is training and decisions around enforcement that need to be ironed out.
