Chapter 10.06 NOISE ORDINANCE ADOPTED
This Ordinance shall be titled Pueblo County Noise Ordinance.
AN ORDINANCE PERTAINING TO THE REGULATION OF NOISE ON PUBLIC AND PRIVATE PROPERTY AND THE OPERATION OF
MOTOR VEHICLES WITHIN THE UNINCORPORATED AREAS OF PUEBLO COUNTY, COLORADO
(Ord. 2011-22 § 1)
C.R.S. § 30-15-401, et seq., enables counties to adopt ordinances for the control or licensing of those matters of purely local concern, and to do all acts and make all regulations which may be necessary or expedient for the promotion of health or the suppression of disease.
C.R.S. § 30-15-401 (1)(m) enables counties to enact ordinances which regulate noise on public and private property and, pursuant to C.R.S. § 25-12-107, counties may adopt resolutions or ordinances prohibiting the operation of motor vehicles within their respective jurisdictions that produce noise in excess of the sound levels in decibels, measured on the “A” Scale on a standard sound level meter having characteristics established by the American National Standard Institute, publication S1.4 – 1971, and measured at a distance of fifty feet from the center of the lane of travel and within the speed limits specified herein. (Ord. 2011-22 § 2)
This Ordinance shall apply in the unincorporated areas of Pueblo County. (Ord. 2011-22 § 3)
For the purposes of this Ordinance, the words and phrases shall have the meanings ascribed to them in this Section:
4.1 Decibel is a unit used to express the magnitude of a change in sound level. The difference in decibels between two (2) sound pressure levels is twenty (20) times the common logarithm of their ratio. In sound pressure measurements, sound levels are defined as twenty (20) times the common logarithm of the ratio of that sound pressure level to a reference level of 2 X 10-5 N/m2 (Newton's/meter squared). As an example of the effect of the formula, a three-decibel change is a one-hundred-percent increase or decrease in the sound level, and a ten-decibel change is a one thousand-percent increase or decrease in the sound level.
4.2 db(A) means sound levels in decibels measured on the "A" scale of a standard sound level meter having characteristics defined by the American National Standards Institute, publication S.4- 1970, and approved by the Industrial Commission of Colorado.
4.3 Residential zone means an area of single-family or multifamily dwellings where businesses may or may not be conducted in such dwellings. The zone includes areas where multiple unit dwellings, high-rise apartment districts, and redevelopment districts are located. A residential zone may include areas containing accommodations for transients such as motels and hotels and residential areas with limited office development, but it may not include retail shopping facilities. Residential zone includes hospitals, nursing homes and similar institutional facilities.
4.4 Commercial zone means:
a. An area where offices, clinics and the facilities needed to serve them are located;
b. An area with local shopping and service establishments located within walking distances of the residents served;
c. A tourist-oriented area where hotels, motels and gasoline stations are located;
d. A large integrated regional shopping center;
e. A business strip along a main street containing offices, retail businesses and commercial enterprises;
f. A central business district; or
g. A commercially dominated area with multiple unit dwellings.
4.5 Light industrial and commercial zone means:
a. An area containing clean and quiet research laboratories;
b. An area containing light industrial activities which are clean and quiet;
c. An area containing warehousing; or
d. An area in which other activities are conducted where the general environment is free from concentrated industrial activity.
4.6 Industrial zone means an area in which noise restrictions on industry are necessary to protect the value of adjacent properties for other economic activity, but shall not include agricultural operations.
4.7 Motor vehicle sound system means any radio, tape player, CD player, amplifier, speakers or other electronic components located in or upon any motor vehicle and used or capable of being used for the production of sound. (Ord. 2011-22 § 4)
The making and creating of an excessive or unusually loud noise, or a noise which is unreasonable and objectionable because it is impulsive, continuous, rhythmic, periodic or shrill within the unincorporated areas of Pueblo County as heard and measured in the manner prescribed by Section 6 is hereby declared to be a public nuisance and unlawful. (Ord. 2011-22 § 5)
For purposes of determining and classifying any noise as excessive or unusually loud as declared to be unlawful and prohibited by this Ordinance, the following test measurements and requirements shall be applied.
6.1 Noise occurring within the jurisdiction of the unincorporated areas of Pueblo County shall be measured at a distance of at least twenty-five (25) feet from a noise source located within the public right-of-way, and if the noise source is located on private property or property other than the public right-of-way, at least twenty-five (25) feet from the property line of the property on which the noise source is located.
6.2 The noise shall be measured on the "A" weighing scale on sound level meter of standard design and quality and having characteristics established by the American National Standards Institute.
6.3 For purposes of this Ordinance, measurements with sound level meters shall be made when the wind velocity at the time and place of such measurement is not more than five (5) miles per hour, or twenty-five (25) miles per hour with a wind screen.
6.4 In all sound level measurements, consideration shall be given to the effect of the ambient noise of the environment from all sources at the time and place of such level measurement. (Ord. 2011-22 § 6)
7.1 Every activity to which this Ordinance is applicable shall be conducted in a manner so that any noise produced is not objectionable due to intermittence, beat, frequency or shrillness. Sound levels of noise radiating from the property line at a distance of twenty-five (25) feet or more therefrom, in excess of the db(A) established for the time period and zones listed in this Section, shall constitute prima facie evidence that such noise is a public nuisance.
7:00 a.m. to 7:00 p.m. to
Zone next 7:00 p.m. next 7:00 a.m.
Residential 55 db(A) 50 db(A)

7.2 In the hours between 7:00 a.m. and the next 7:00 p.m., the noise levels permitted in Section 5 may be increased by ten (10) db(A) for a period not to exceed fifteen (15) minutes in any one-hour period.
