Proposal: The Seattle Department of Planning and Development (DPD) has reviewed an application from Sound Transit for a technical noise variance from the standards for nighttime construction noise for above-ground construction activities in support of underground tunneling at the University of Washington Station (UWS) site. Sound Transit proposes to construct twin bored tunnels running from the UWS site to the Capital Hill Station site located at Broadway and East Denny Way. This is the northern most portion of the University Link light rail system which will provide light rail transit service from the University of Washington to downtown Seattle. Sound Transit's application includes a detailed noise analysis combined with a nighttime noise control mitigation plan and 3rd party noise monitoring oversight. Sound Transit proposes new upper limits for on-site construction noise created at night, and applies only to the University Link UWS site. Project Number: 3010245 Appealable Decision: The technical variance request is conditionally granted. Numerous conditions are included in the decision and include: Applicant is required to follow and execute all noise control measures identified in the application, its appendices and attachments. Nighttime project sound levels are limited to ensure they will not exceed the ambient sound level by more than 6dBA from 10:00 pm to 7:00 am weekdays and from 10:00 pm to 9:00 am on weekends and holidays. Solid construction walls shall be installed prior to commencement of nighttime noise-producing construction activities on site. The Construction Noise Management and Mitigation Plan must be approved by DPD prior to the commencement of nighttime construction activities on site. The applicant shall notify the DPD Noise Administrator and those community members included in the original application two weeks prior to the commencement of activity that is subject to this variance.
