§ 4-24.301. Maximum permissible sound levels by land use categories.¶
The noise standards for the various categories of land use districts identified shall be the higher of either the presumed or actual measured ambient and shall apply to all such property within a designated category as follows:
| Receiving Land Use District Category | Time Period | Presumed Ambient Level (dBA) |
|---|---|---|
| Low Density | 10:00 p.m. to 7:00 a.m. | 45 |
| Residential R-1-A, R-1, R-2, P-D-R, P-U-D Overlay | 7:00 a.m. to 10:00 p.m. | 50 |
| Medium Density | 10:00 p.m. to 7:00 a.m. | 50 |
| Residential R-3, R4, P-D-R, P-U-D Overlay | 7:00 a.m. to 10:00 p.m. | 55 |
| High Density | 10:00 p.m. to 7:00 a.m. | 55 |
| Residential R-5, R-6, P-D-R, P-U-D Overlay, C-I | 7:00 a.m. to 10:00 p.m. | 60 |
| Commercial NSC, | 10:00 p.m. to 7:00 a.m. | 60 |
| CSC, GC, P-D-C | 7:00 a.m. to 10:00 p.m. | 65 |
| Industrial P-D-I | 10:00 p.m. to 7:00 a.m. | 60 |
| Industrial P-D-I | 7:00 a.m. to 10:00 p.m. | 65 |
| Industrial P-I | 10:00 p.m. to 7:00 a.m. | 70 |
| Industrial P-I | 7:00 a.m. to 10:00 p.m. | 70 |
As indicated above, the presumed ambient levels in the Planned Development Residential (P-D-R) and the Planned Unit Development (P-U-D) Overlay land use districts are categorized so as to be consistent with the actual density of the development. The presumed ambient levels for the Planned Development (P-D) and the Civic Center (C-C) land use districts shall be consistent with those established for the lowest adjacent land use district.
(a) Correction for time characteristics. No person shall operate, or cause to be operated, any source of sound at any location within the City or allow the creation of any noise on property owned, leased, occupied, or otherwise controlled by such person which causes the noise level when measured on any other property to exceed:
(1) The noise standard of the receiving land use district for a cumulative period of more than 30 minutes in any hour; or
(2) The noise standard of the receiving land use district plus five dB for a cumulative period of more than 15 minutes in any hour; or
(3) The noise standard of the receiving land use district plus 10 dB for a cumulative period of more than five minutes in any hour; or
(4) The noise standard of the receiving land use district plus 15 dB for a cumulative period of more than one minute in any hour; or
(5) The noise standard of the receiving land use district plus 20 dB for any period of time.
(b) Levels exceeding the noise limit categories. If the measured ambient level exceeds that permissible as set forth in subsections (1), (2), (3), and (4) of subsection (a) of this section, the allowable noise exposure standard shall be increased in five dB increments as appropriate to encompass or reflect such ambient noise level. In the event the ambient noise level exceeds the noise level set forth in subsection (5) of subsection (a) of this section, the maximum allowable noise level shall be increased to reflect the maximum ambient noise level.
(c) Correction for location of noise source. If the measurement location is on a boundary between two different land use district categories, the noise level limit applicable to the lower land use district category, plus five dB shall apply.
(d) Correction for ambient noise levels when alleged offending sources cannot be shut down. If possible, the ambient noise shall be measured at the same location along the property line utilized in subsection (a) of this section with the alleged offending noise source inoperative. If for any reason the alleged offending noise source cannot be shut down, then the ambient noise shall be estimated by performing a measurement in the same general area of the source, but at a sufficient distance such that the offending noise from the source is inaudible. If the difference between the noise levels with the noise source operating and not operating, with the utilization of either of the above-described methods of measurement, is six dB or greater, then the noise measurement of the alleged source can be considered valid.
(e) Correction for character of sound. In the event the alleged offensive noise contains a steady audible tone, such as a whine, screech, or hum, or is a repetitive noise, such as hammering or riveting, the standard limits set forth in this section shall be reduced by five dB.
