Chapter 9 — 1025M - PERFORMANCE STANDARDS

Tables:

9-1025.6M - LIGHT AND GLARE.

The regulations concerning light and glare shall be as specified in the development title with the following modifications:

(a)

Shielding or Recessing. Exterior lighting shall be shielded or recessed to minimize direct glare and reflections.

(b)

Prohibitions. Lighting of unusually high intensity or brightness is prohibited.

(Ord. 3813 (part), 1994)

9-1025.9M - NOISE.

The regulations concerning noise shall be as specified in the development title with the following modifications:

(a)

Standards for Commercial and Industrial Uses. For new commercial uses, industrial uses or utilities, the exterior, non-transportation noise level performance standards specified in Table 9-1025.9M shall be applicable.

(b)

Standards for Residential Uses.

(1)

New residential development shall not be allowed where noise levels due to stationary noise sources would exceed the exterior noise level standards set forth in Table 9-1025.9M.

(2)

Noise levels from mobile noise sources in primary outdoor use areas of new residential development shall not exceed an Ldn of sixty (60) dB unless the project design includes mitigation measures to reduce noise in outdoor activity areas to sixty (60) dB, or as reasonably close to sixty (60) dB as is possible. Where it is not possible to reduce noise in outdoor activity areas to an Ldn of sixty (60) dB or less, an exterior noise level of up to, but not exceeding, an Ldn of sixty-five (65) dB may be allowed by the Review Authority.

(3)

Exterior noise levels shall not create an interior noise level exceeding forty-five (45) dB.

(4)

Noise studies for specific residential projects proposed in areas with noise levels from mobile sources above Ldn sixty (60) dB shall address how noise levels in outdoor areas could be maintained at or below an Ldn of sixty-five (65) dB.

(c)

Standards for Other Specified Uses.

(1)

Noise-sensitive land uses other than residential uses shall not be allowed where noise levels due to stationary noise sources would exceed the exterior noise level standards set forth in Table 1025.9M.

(2)

On school sites and other noise-sensitive land uses, any outdoor instructional areas or areas which require speech audibility shall be located outside the sixty (60) dB Ldn noise contour from mobile sources or shielded from mobile noise in excess of sixty (60) dB Ldn.

(3)

Exterior noise levels shall not create an interior noise level exceeding forty-five (45) dB.

(4)

Noise studies prepared for noise-sensitive land uses shall address how noise levels in outdoor areas from mobile sources shall be maintained at or below an Ldn of sixty (60) dB.

(d)

Noise-Attenuation Measures. In addition to the noise-attenuation measures specified in the development title, the following additional measures shall be applicable:

(1)

Until such time as residential, school or other noise-sensitive development is proposed within one thousand (1000) feet of the railroad tracks in Mountain House, or until such time as rail use is initiated within the community, noise mitigation shall be limited to a sound wall along the tracks between the proposed transit station and Marina Boulevard.

(2)

Residential development shall be set back from the centerline of 1-205 a sufficient distance to satisfy Master Plan noise policies after the inclusion of sound mitigation improvements such as berms and soundwalls.
