9-404.090 - NOISE ATTENUATION MEASURES

Any project subject to the acoustic study requirements of Section 9-404.080 may be required to incorporate noise attenuation measures deemed necessary to ensure that noise standards established in Tables 9-404.040 are not exceeded as a Condition of Approval.

(a)

New noise-sensitive uses must incorporate noise-attenuation measures to achieve and maintain the interior noise level listed in Table 9-404.040 for each specified noise sensitive land use.

(b)

The preferred noise attenuation measures are those based on site planning and building orientation along with noise-abating materials, technology, and construction standards to minimize noise. Noise barriers for attenuation should be used only after all feasible design-related noise measures have been incorporated into the project. Where noise barriers are used, they must provide noise reduction to meet the limits for outdoor and indoor noise in Table 9-404.040.
