A town I'm working for has had me draft some fairly restrictive regs. concerning outdoor dining areas adjacent to residential uses. With teh Throbbing Brains help I was able to put something together that I think is simple, too the point, and a darned good ordinance overall, for their lacking zoning code. The town is happy but have asked me to add a condition on noise levels. They've purchased a decibel meter and are looking for a way to use it. I've researched acceptable levels of noise when measured from the adjoining property line but have not been able to find anything on specific decibel readings. Any suggestions on where to look?
