shall identify appropriate measures for reducing construction noise levels to below 60 dB(A) hourly Leq or prevent any increases in the ambient noise levels at the edge of the occupied coastal sage scrub habitat if existing noise levels are 60 dB(A) hourly Leq or greater. Noise reduction measures may include operational adjustments, such as placing noisy equipment at greater distances from the habitat or shortening the operating period of noisy equipment, and/or installing temporary noise walls or curtains to block excess noise from entering the occupied habitat. If noise reduction measures are required, bi-weekly monitoring of the bird(s) shall be conducted by the qualified biologist to observe if the bird(s) is being affected by construction activities. The acoustical consultant shall confirm through noise measurements that the noise reduction measures are effective at preventing noise levels in excess of 60 dB(A) hourly Leq or an increase in ambient noise levels.
