Hi Tammy,
See the link below for some examples of what activities are typical at different dB levels.

OSHA certifies decibels meters and our Code Compliance staff will be nationally certified in the use
and calibration of these meters. Please let me know if you have any additional questions. - Marty

Hi Marty,The hours sound reasonable to me and also this is possibly more enforceable. My onlyquestions are how was the decibel level decided on and how would a typical person or theenforcers be able to know when it is over 60 dbs? I don't have a sense of how loud that is. Thanks, Tammy ---------- Forwarded message ---------From: Rob Pertzborn <rpertzborn@intrinsikarchitecture.com>Date: Tue, Sep 28, 2021 at 11:26 AMSubject: FW: Proposed changes to the Noise Ordinance re: construction hourTo: Rob Pertzborn <rpertzborn@intrinsikarchitecture.com>

Dear Construction Professionals,
As requested by the City Manager and City Commission, staff drafted changes to the City’s“Noise Ordinance” and will present these changes to the City Commission on October 26,
2021 for its consideration. I am writing you today to let you know about these proposedchanges in advance and to offer you a chance to provide input.
City Code currently limits construction activities in most residential zone districts to the hours
of 6:00am to 10:00pm and uses a “reasonable person” standard to measure the noise level. Ingeneral terms the proposed ordinance would implement a decibel standard and limit
construction activities that exceed 60 decibels to daytime hours, between 7:00am and 8:00pm.The actual language is below.
“Noise emanating from a construction operation occurring between the hours of 8:00
PM to 7:00 AM is prohibited from exceeding 60dB(A) as measured at the property lineof an immediately adjacent property.”
I have attached the proposed ordinance in .pdf format so that you can see the draft changes.
Please be aware that this a draft version and that the language is still subject to changes. Theunderlined verbiage is the proposed new text and the strike-out text is current City Code that
would no longer be applicable. Input suggesting changes to the proposed ordinance should be
sent directly to me prior to October 1st at: mmatsen@bozeman.net. I appreciate your feedback
even though I cannot guarantee that your suggested changes will be included in the proposedordinance.
Staff is planning to present this revised ordinance to the City Commission for discussion and a
vote on Tuesday, October 26th. As always you may send public comment expressing generalsupport or displeasure to City Commissioners at agenda@bozeman.net. Keep in mind that all
comments will be available for public view.
Thank you for your time and consideration.
Best Regards – Marty
