6-36-040 Use District Noise Levels--Maximum Permissible Sound Levels

No person shall operate, or permit to be operated, on public or private property any stationary source of sound in such a manner as to create a sound pressure level which exceeds the limits set forth for the receiving land use category identified as the “Use District” for more than six (6) minutes in sixty (60) aggregate minutes which may be measured at or within the real property boundary of the receiving land use.

Use District: Night Day

Night 7p.m. to 7a.m. Residential 50 dB(A) 55 dB(A)

Day 7a.m. to 7p.m. Business 60 dB(A) 65 dB(A)

Industrial 60 dB(A) 65 dB(A)

Construction Not Allowed 80 dB(A)

When a noise source can be identified and its noise measured in more than one land use category, the limits of the most restrictive use shall apply at the boundaries between the different land use categories. This provision shall not apply to construction activities holding a valid building permit issued by Pitkin County when the least restrictive use is a floating construction district, in which case the limits applicable to the construction district shall apply, notwithstanding the boundaries of the more restrictive uses, because of the temporary nature of the construction use. For construction activities not holding a valid building permit the land use district levels apply.
