(Commissioners ) Approved a new noise ordinance. Excessively loud noise, such as from stereos, won't be tolerated. Also, motorized lawn equipment such as mowers, trimmers or blowers can't be run after 7 p.m. or before 8 a.m. Construction can only take place between 9 a.m. to 6 p.m., though contractors may ask the city manager for exemptions.
