Technology Associates <br />The requested variance for not undergrounding the ancillary facilities is not <br />sufficiently supported by the application materials. Please respond to the above <br />criterion. <br />RESPONSE: To meet the above criterion, the equipment shelter extension has been oriented <br />away from nearby residential uses to face the church playground and Fox Hollow Road. In <br />addition, all substantial offsite impacts have been mitigated through design of the <br />equipment enclosure as an architecturally compatible extension of the existing church with <br />extensive sound baffling which will reduce the noise levels of the facility equipment to well <br />below the City's noise limits. The proposed ground equipment includes AC units and an <br />emergency generator, which would both be fully enclosed within a sound-baffled equipment <br />shelter, built to look like a seamless extension of the church building. The AC units would run <br />intermittently to cool equipment. The emergency generator would run only in emergencies and <br />for about 10 consecutive minutes during monthly testing. The proposed design incorporates <br />additional baffling sufficient to reduce the sound from the AC units to 35 dBA, well below the 45 <br />dBA code limit for R-1-zoned properties. Because the proposed generator would run for such a <br />short amount of time during daytime hours, it would not be considered a noise disturbance <br />under the code even if the noise level briefly exceeds 45 dBA. (Per Matt Denberg, City of Eugene <br />Code Compliance, Oct. 22, 2014. See generally, EC 6.750(b).) However, to minimize the noise <br />levels from the generator, it would be enclosed within the sound-baffled equipment shelter and <br />additional noise control can be added to assure that all substantial offsite impacts have been <br />mitigated and that the 45dBA noise level at the property lines is achieved. <br />Because testimony at hearing will demonstrate that the emergency generator cannot be safely <br />placed underground and because the criterio for a variance from that requirement have been <br />met, the Applicant is not proposing an underground alternative. The proposed design is fully <br />enclosed with additional sound baffling. <br />Applicant also proposes new landscaping around the perimeter of the building extension so the <br />ancillary equipment stored inside it will be completely stealthed and have minimal visual <br />impact. Moreover, Applicant has provided a noise study that includes mitigation measures <br />ensuring that the site meets or exceeds Eugene's noise reduction code requirements. <br />7117 SW Beveland Street, Suite 101 <br />Tigard, OR 97223 <br />(323) 559-14103 <br />Email: acab.tlnne taec.net <br />www,taec.net <br />13 <br />
