Dear Ms Henning:
RE: XL 4743 Noise Variance Request
SR 167/NB S 212th St to I-405 – Paving - MP 23.65 to MP 26.12
Dear Ms. Henning:
The purpose of this letter is to request a 36 non-consecutive nights of temporary noise variance to complete roadway rehabilitation and other project repairs along northbound SR 167
within City of Renton. WSDOT Acoustics group requests relief from the requirements of the Renton Municipal Code, Title VIII – Health Sanitation - Chapter 7- and Noise Level Regulations,
as per section 8-7-2 and the Washington State Administration Code (WAC) Chapter 173-60, allowing the WSDOT representative to work at night. The project ad date is set for November 23rd,
2015. The project is planned to commence in April 1, 2016 with a contract completion of October 31, 2016
Project Narrative
The project is located along State Route 167 from Mile Post 22.30 to Mile Post 26.12, the work within the City of Renton will be between Milepost 23.65 to MP 26.12 as shown in the attached
Vicinity Map (Attachment 1). The SR 167 project includes the following items of work and improvements within the State Right of Way limits only of the within the highway roadway.

Table 1: Project items of work, number of nights equal 36 non consecutive nights
This project requires Street Use Permits and Detour Permits which will be applied for separately.
The project will include nighttime work where the zoning varies from residential, hotels, commercial, and light industrial zoning designation.
Traffic Limitations
The primary reason for conducting nighttime work is to avoid daytime traffic congestion on SR 167 within the city of Renton. Day time full and partial closures along this well-traveled
route are expected to cause disruption in the urban circulation as well as increase travel times for the citizens of Renton. Partial closures may impact commercial and business traffic
during business hours as well as delays to school routes and normal road users. Furthermore, data shows that day time closures could increase traffic accidents and compromise the safety
of workers and the traveling public within the construction zones. Attachment 1 lists the proposed lane closures for the SR 167 highway.
Construction Equipment and predicted noise impacts during nighttime operations
The construction equipment is described in Table 2 included in Attachment 3 along with the estimated noise prediction to nearby receivers approximately 50’ as well as proposed mitigation
measurements.
Proposed Nighttime Noise Mitigation
WSDOT will require the contractor to adhere to the following noise reduction measures:
All vehicles shall be equipped with ambient sensitive backup warning devices. The Contractor may use back-up observers in lieu of back-up warning devices for all equipment except dump
trucks in compliance with WAC Chapter 296- 155-610 and 296- 155-615. The Contractor shall use back-up observers and back-up warning devices for dump trucks in compliance with WAC Chapter
296- 155-610.
Truck tailgate banging is prohibited. All trucks shall be secured to prevent excessive noise from banging.
All trucks performing export haul shall have well maintained bed liners as inspected and approved by the Engineer.
A copy of noise variance shall be kept on the project site at all times.
Construction and stationary equipment, such as light plants, generators, compressors, and jackhammers must utilize WSDOT approved noise mitigation shields, noise blankets, skirts, or
other means available as approved by the Engineer when feasible;
Provide a WSDOT complaint number as well as a list of designated contact persons for the purpose of forwarding complaints;
The Contractor notifies residents, within 500 feet of the project corridor, of nighttime work activities at least 14 calendar days in advance of the proposed nighttime construction work.
The Project engineer administering the projects are listed as follows
Mike Askarian P.E.;
askarim@wsdot.wa.gov

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.
Sincerely,
/
