RE: Temporary Noise Variance Request
NWR South 23 – 25 Pavement Repair Project XL6747
SR 167 Milepost (MP) 26.18 to MP 27.18
SR 515 MP 6.70 to MP 6.93
Dear Mr. Morganroth:
The Washington State Department of Transportation (WSDOT) requests a temporary noise
variance for 15 cumulative nights from the City of Renton for the NWR South 23 - 25
Pavement Repair Project along SR 167 and SR 515. WSDOT is requesting a relief from the
requirements of Renton Municipal Code (RMC) Chapter 8-7-2 (Noise Level Regulations,
Maximum Environmental Noise Levels) and the Washington Administrative Code (WAC)
173-60-040 through approval of a noise exemption as allowed under WAC 173-60-050(f),
allowing WSDOT contractor(s) to work nights between the inclusive dates of April 1, 2025
to December 31, 2025.
Project Description
This project will provide crack sealing and asphalt patching on highways in Maintenance
Areas 4 and 5 covering SR 515, SR 167, SR 161, SR 18, SR 523, SR 520, I-405, SR 202, I-
90, and I-5 ramps. NWR Materials has determined that numerous routes require strategic
preservation before a paving project can be programmed to address deteriorating roadway
conditions.
Specifically for the City of Renton, this project will occur along SR 167 MP 26.18 to MP
27.18 and SR 515 MP 6.70 to MP 6.93.

Construction Activities and Equipment
Equipment that may be used includes backhoe/excavator; backup and movement alarm;
ground compactor; air compressor; diamond concrete grinder; concrete mixer truck; concrete
saw; flatbed truck; generator; jackhammer; joint sealer; light tower; asphalt paving – paver,
dump truck, and material transfer vehicle (MTV); concrete paving – texturing, curing
machine and pickup truck; power tools – air hose and grinder; roller; vacuum street sweeper;
and traffic control equipment such as truck mounted attenuators and portable changeable
message signs.
Justification for Nighttime Work
WSDOT traffic recommends that lane closures be done at night when traffic volumes are low
enough to handle closures. Construction related lane closures during the daytime could cause
delays to the traveling public, impact bus routes and business access, jeopardize workers’ and
public safety. Performing work at night will minimize the danger to workers and the
traveling public from road closures, detours and traffic delays. In addition, daytime lane
closures could backup and adversely impact traffic and city arterials. Therefore, lane
closures during the nighttime are necessary for this project.
Traffic Limitations
Lane closures are expected weeknight, Monday to Thursday, from 9 PM to 5 AM.
Proposed Nighttime Noise Mitigation
WSDOT is committed to reducing the inconvenience felt by those living near this project and
will make reasonable efforts to minimize sound levels caused by nighttime work. To that
end, WSDOT will require the contractor to adhere to the following noise reduction measures:
1. All trucks performing export haul shall have well maintained bed liners as inspected and approved by the Engineer.
2. Truck tailgate banging is prohibited. All truck tailgates shall be secured to prevent excessive noise from banging. 3. A copy of noise variance shall be kept on the project site at all times.
The construction Project Engineer in charge of administering the contract is:

Should construction activities associated with this project cause noise impacts, we request
your help resolving any complaint we may receive by notifying the Project Engineer within
24 hours of occurrence.
