Q. How do I know what the permissible sound levels are with a noise permit or sound variance?
A.
The following are the maximum permissible sound levels allowed at or within the real property boundary of a receiving land use (receiving land use is defined as the use or occupancy of the property which receives the transmission of sound):

1. Residential Zone: 7 am – 10 pm has a 60 decibel sound limit.
2. Residential Zone: 10 pm – 7 am has a 50 decibel sound limit.
3. Commercial Zone: At all times has a 65 decibel sound limit.
4. Industrial Zone: At all times has a 75 decibel sound limit.
5. Noise Sensitive Area: At all times has a 55 decibel sound limit.

Most generally for a noise permit or sound variance you will be limited to 60 decibels when measured at the real property boundary of the private residence nearest the sound equipment and measuring not more than 100 decibels at a distance of fifty feet from the sound equipment. Upon your request (and depending on officer availability) an officer can come test the sound levels for you prior to your event to ensure you know the level at which you should be to hold your event within the confines of the maximum decibel levels.

 

 

QHow many different types of permits/variances are there?

A.  There are 3 types of Noise Permits:

1.  Type A permit – General.  Sound Equipment permitted under a Type A permit may  be used only in areas of the City zoned for nonresidential use and only between the hours of 9:00 am and 2:00 am the following morning.

Sound Equipment permitted under a Type B permit is mounted upon a motor vehicle and intended for use upon City streets provided that the sound equipment emits only music or human speech registering not more than 80 decibels when measured at a distance of one hundred feet from the sound equipment and only in nonresidential areas from 9:00 am to 9:00 pm.

3.  Type C permit – Parks.  Sound equipment permitted under a Type C permit may be used only in public parks owned and operated by the City, or public grounds owned and operated by another governmental body, from 10:00 am to 11:00 pm for events authorized and approved by the Park and Recreation Board or other body having jurisdiction over the park or public grounds.
