The city divides every parcel into three noise zones under § 9.30.050. Zone I covers single, double and multiple-family residential property; Zone II covers commercial and mixed-use property; Zone III covers manufacturing and industrial property. On weekdays (Sunday through Thursday), Zone I may not exceed 45 dB(A) between 10:00 p.m. and 7:00 a.m. and 55 dB(A) the rest of the day; Zone II is capped at 60 dB(A) overnight and 70 dB(A) by day.

Zone III runs the same 60 dB(A) night / 85 dB(A) day split every day of the week with no weekend change.
