amplified sound both indoors and outdoors at the marketing events. Amplified sound is permitted at both indoor and outdoor special events and both indoor and outdoor marketing events pursuant to Development Title Section 9-1075.8 (i). However, a noise study was required to identify possible mitigation measures for any amplified noise source impacts. A noise study was conducted by J. C. Brennan and Associates dated October 25, 2012. The noise study concluded the proposed winery can comply with the county noise level standards provided the following recommendations are implemented: 1) Conduct periodic noise measurements during events at a distance of 100 feet directly in front of the sound system, and should be limited to no more than 75 dBA or Lmax; 2) The winery staff is trained on how to use the sound level meter, use the proper settings on the meter and the meter is calibrated prior to events. The sound level meter shall comply with an ANSI Type 1 or Type 2 certification; 3) Events are required to terminate prior to 10:00 p.m. These mitigation measures are incorporated into the Conditions of Approval. Additionally, marketing events must comply with Development Title Section 9-1025.9 regarding stationary noise standards (50 dB Hourly Equivalent Sound Level daytime, 45 dB Hourly Equivalent Sound Level nighttime, 70 dB maximum sound daytime, 65 dB maximum sound nighttime). Each of the noise level standards shall be reduced by 5 dB for noise primarily consisting of speech or music. Marketing events must end by 10:00 p.m. Therefore, any noise impacts from this project will be less than significant. Oak Trees The site contains a number of heritage and native oak trees. A heritage oak tree is defined as a native oak tree that has a single trunk diameter of thirty-two (32) inches or greater measured at four and one-half (4'/z) feet above the average ground elevation of the tree. A native oak tree is defined as a valley oak with a trunk diameter of six (6) inches to less than thirty-two (32) inches for a single trunk tree, or a combined trunk diameter of eight (8) inches or greater for a multi- trunk tree measured at four and one-half (4Yz) feet above the average ground elevation of the tree; or an interior live oak, California live oak, or blue oak with a trunk diameter of four (4) inches to less than thirty-two (32) inches for a single trunk tree, or a combined trunk diameter of six (6) inches or greater for a multi-trunk tree measured at four and one-half (4Yz) feet above the average ground elevation of the tree (Development Title Section 9-110.4). The site plan depicts one native oak tree that the applicant intends on removing. A native oak tree may be removed subject to an approved Improvement Plan. Trees removed under the provisions of this Section shall be replaced subject to the following requirements: • Replacement stock shall be of healthy commercial nursery stock or acorns, of the species removed or other approved species, and shall be established and maintained for at least three (3) years (Development Title Section 9-1505.4[a]). • Replacement trees shall be planted as near as possible to the location of the removed tree or in an alternative location acceptable to the Review Authority (Development Title Section 9-1505.4[b]). • Replacement stock shall be planted between October 1 and December 31, and no later than twelve (12) months after the date of tree removal (Development Title Section 9- 1505.4[c]). 3
