New noise law for Grays Harbor

Grays Harbor has new a noise law.

At their Monday meeting the Grays Harbor County Commissioners passed an ordinance that established maximum permissible noise levels and uses the state guidelines.

In the Washington Administrative Code, the state sets “maximum permissible environmental noise levels” for all residents, saying that “No person shall cause or permit noise to intrude into the property of another person which noise exceeds the maximum permissible noise levels”.

It states that between 7am and 10pm, noise limits in residential areas not covered by a local zoning ordinance, the maximum level of noise is 60 dBA.

Between 10pm and 7am, the maximum level drops to 50 dBA.

There are exceptions to these levels.

This includes activities such as home repair, firearms, car racing, parades, and other events.

There are also changes in the levels for commercial and industrial areas, as well as increases in all areas for brief periods.

Commissioner Wes Cormier said it is a property rights issue.

Commissioner Randy Ross said the issue was brought up by the Sheriff’s Office and that this change puts “some meat back into the law”.

The ordinance was passed unanimously and is effective immediately.
