APPLICABLE SECTIONS OF THE RENTON MUNICIPAL CODE: Title VIII, Chapter 7 Noise Level Regulations F. FINDINGS OF FACT (FOF): The Planning Division of the City of Renton accepted the above master application for review on September 5, 2024 and determined the application complete on September 12, 2024. The project complies with the 120-day review period. The project site is located along two (2) state highways, including approximately 0.23 linear miles of SR 515 and one (1) linear mile of SR 167. The project site is currently developed as State Route 515 and State Route 167. The site is mapped with regulated slopes, streams, wetlands, high seismic hazards, flood hazards, high landslide hazards, high erosion hazards, and wellhead protection area zones. The purpose of the project is to provide crack sealing and asphalt patching on various highways in WSDOT Maintenance Areas 4 and 5. The work is proposed to begin in April of 2025 and end in December of 2025. Nighttime work is proposed for the entire life of the project. The applicant is requesting approximately 15 cumulative nights of work to complete the maintenance project (Exhibit 7). Staff received one (1) public comment from Emmeline Aquino with the King County Wastewater Treatment Division on September 26, 2024 (Exhibit 8) related to the wastewater infrastructure near the proposed work. Staff responded to Ms. Aquino on September 26, 2024 (Exhibit 9). Staff forwarded the public comment to the applicant the same day it was received. No other public or agency comments were received. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. Variance Analysis: The Washington State Department of Transportation (WSDOT) is requesting a noise variance from RMC 8-7 in order to exceed the nighttime noise limits between the hours of 10 pm and 7 am. The proposal is compliant with the following variance criteria, pursuant to RMC 8-7-8.D. Therefore, staff recommends approval of the requested variance. Compliance Variance Criteria and Analysis  ( That the applicant suffers practical difficulties and unnecessary hardship and the variance is necessary because of special circumstances applicable to the applicant’s property or project, and that the strict application of this Chapter will deprive the subject property owner or applicant of rights and privileges enjoyed by others. Staff Comment: WSDOT is requesting a noise variance to complete night work on sections of SR 515 and SR 167 within Renton City Limits. According to the applicant, WSDOT traffic engineers recommend the lane closures required for the work to be completed occur during nighttime hours to avoid delays to the traveling public, impacts to bus routes and business access, and to ensure worker safety. The NWR South 23 – 25 Pavement Repair Project is part of a larger project in WSDOT Maintenance Areas 4 and 5, which covers SR 515, SR 167, SR 161, SR 18, SR 523, SR 520, I‐405, SR 202, I‐90, and I‐5 ramps. The overall project is intended to provide strategic preservation before a future major roadway rehabilitation project can occur. This variance is being requested to provide crack sealing and asphalt patching on portions of SR 515 and SR 167 in the City of Renton (Exhibits 4 and 5). Both SR 515 and SR 167 serve as essential transportation connectors for commercial, freight and motorist uses, and mass transit within the Puget Sound area. According to the applicant, one of the goals of the project is to provide safe and efficient movement of people, goods, and services through and around any closures on the project while minimizing negative impacts to residents, commuters, and businesses. To meet these requirements, the applicant contends that it is necessary that some of the work for this project be done at night. The applicant maintains that working at night is considered the best way to minimize the negative effects of construction. In addition, WSDOT has indicated that safety for drivers and construction workers improves when work is conducted at night. The requested variance would allow for temporary exceedance of noise level limits during the nighttime hours (between 10:00 pm and 7:00 am) which would allow the project to be completed without exacerbating the existing day time traffic conditions. The pieces of construction equipment and types of construction activities needed to complete the work would include a backhoe, ground compactor, air compressor, diamond concrete grinder, concrete mixer truck, concrete saw, flatbed truck, generator, jackhammer, joint sealer, light tower, asphalt paver, dump truck, material transfer vehicle, texturing and curing machine, air hose, grinder, roller, vacuum street sweeper, and traffic control equipment (Exhibit 6). Staff concurs with the applicant that the location of the work within SR 515 and SR 167 are near some of the most heavily travelled intersections in Renton. In addition, the project is expected to temporarily impact city roads, primarily main arterials. Therefore, the variance is necessary because of the special circumstances applicable to the project location. The city would work with WSDOT on a daily basis to ensure the project would have the least amount of impact on users and city residents. The proposed nighttime work is expected to mitigate the potential day time impacts on residents, road users and area businesses. By allowing nighttime work to exceed the Environmental Designation for Noise Abatement (EDNA) for all classes (Class A, Class B and Class C) of properties, the applicant can complete the project in a more timely manner and limit the impacts on the community and improve safety for drivers and construction workers.

( That the granting of the variance will not be materially detrimental to the public health, welfare or safety, or unduly injurious to the property or improvements in the vicinity of the location for which this variance is sought. Staff Comment: According to the applicant, the proposed project addresses deteriorating pavement conditions on sections of roadway heavily used by the public, and temporary nighttime construction is one of the few tools that WSDOT is able to employ to lessen traffic congestion and disruption to highway users while improving the roadway. WSDOT acknowledges that this project would impact local arterials and streets for short period of times following a construction program schedule posted with enough notice to the public and working in conjunction with the City of Renton and WSDOT task force. See the Site Plan (Exhibit 2) for the location and type of night work proposed. Noise levels projected for this project have been estimated between 61 to 97 dBA heard at 50 feet (50’) from the source of the noise. These sound levels are expected to diminish to a range of 45 to 81 decibels at a distance of 300 feet (300’) from the source of the noise and nighttime noise levels are not expected to be concentrated at one location for more than a few days. WSDOT has proposed several noise mitigation measures to lower the impacts to nearby residents (Exhibit 7). See subsection ‘d’ for discussion of some of the proposed noise mitigation measures and their effect. Staff concurs with the applicant that the variance would not be materially detrimental to the public health, welfare or safety, or injurious to the property or improvements in the vicinity of the project site. In addition, staff recommends a condition under subsection ‘d’ that would allow staff and the applicant to address complaints from residents in the vicinity of the work area.  ( That the approval is a minimum variance that will accomplish the desired purpose. Staff Comment: According to the applicant, the purpose of the requested noise variance is to allow WSDOT to accomplish this work in the minimum number of nights required to complete all the work at the locations shown on the site plans (Exhibit 2). This request includes approximately fifteen (15) cumulative nights in total, including contingency. Staff concurs with the applicant that the approval is the minimum variance that would accomplish the desired purpose. Mitigation measures are proposed by the applicant to diminish the impact on affected properties near the project as little as possible.  Compliant if All Conditions of Approval are Met That the variance contains such conditions deemed to be necessary to limit the impact of the variance on the residence or property owners impacted by the variance. The variance approval may be subject to conditions including, but not limited to, the following: 1) Implementation of a noise monitoring program; 2) Maximum noise levels; 3) Limitation on types of equipment and use of particular equipment; 4) Limitation on back-up beepers for equipment; 5) Required use of noise shields or barriers; 6) Restrictions to specific times and days; 7) Specific requirements for documentation of compliance with the noise variance conditions; 8) Specific requirements for notification to nearby residents; 9) Required cash security to pay for inspection services to verify compliance; 10) Required access to the project by the City to verify compliance with the noise variance conditions; 11) Specific program to allow for temporary hotel vouchers to affected residents; 1 2) Requirements for written verification that all workers understand the noise variance conditions for the project; and 13) Provision allowing the City to immediately revoke the variance approval if the variance conditions are violated. Staff Comment: WSDOT provided a Variance Application Responses and Mitigation memo (Exhibit 7) to follow RMC 8-7-8.D.4, Factors For Granting Variance. Proposed noise mitigation measures include the following: All trucks performing export haul shall have well maintained bed liners as inspected and accepted by the Engineer. Truck tailgate banging is prohibited. All truck tailgates shall be secured to prevent excessive noise from banging. A copy of the noise exemption shall be kept on the project site at all times. Written notifications detailing the anticipated work schedule, project duration, and a 24‐hour noise complaint number will be sent to all residents and businesses located within 500 feet (500’) of the project boundary, at least 14 calendar days prior to any anticipated nighttime construction work. Contractor and WSDOT personnel must refrain from parking and idling vehicles near residential areas. According to the applicant’s Variance Application Responses and Mitigation memo submitted with the application (Exhibit 7), the applicant would utilize a number of mitigation measures and monitoring techniques to limit impacts on EDNA properties along both project corridors. For example, contractor and WSDOT personnel would refrain from parking and idling vehicles near residential areas and truck tailgate banging is prohibited. The applicant has proposed effective mitigation measures that would limit the anticipated nighttime noise impacts on the impacted properties. In order to ensure that complaints or issues submitted by residents are adequately addressed, the contractor along with WSDOT would work on alternative mitigation measures to stop the disruption. Staff recommends, as a condition of approval, that the applicant and the Design Build Contractor implement the noise mitigation measures (listed above) for granting a variance to diminish or eliminate noise during the NWR South 23 – 25 Pavement Repair project. A summary of any noise-related complaints received and the response provided shall be provided to the city’s project manager within one (1) week of receiving the complaint. In addition, staff recommends, as conditions of approval, the following: The applicant shall post nighttime work on the WSDOT web/internet site so residents have digital access to information that the City of Renton might see as appropriate. All night work shall occur Monday through Friday. The applicant shall provide hotel vouchers if earplugs and white noise machines are not sufficient, as requested by effected residents prior to commencement of excessively noisy nighttime work or within 24 hours of receiving a complaint.   6) Restrictions to specific times and days; 7) Specific requirements for documentation of compliance with the noise variance conditions; 8) Specific requirements for notification to nearby residents; 9) Required cash security to pay for inspection services to verify compliance; 10) Required access to the project by the City to verify compliance with the noise variance conditions; 11) Specific program to allow for temporary hotel vouchers to affected residents; 12) Requirements for written verification that all workers understand the noise variance conditions for the project; and 13) Provision allowing the City to immediately revoke the variance approval if the variance conditions are violated.

In addition, staff recommends, as conditions of approval, the following: The applicant shall post nighttime work on the WSDOT web/internet site so residents have digital access to information that the City of Renton might see as appropriate. All night work shall occur Monday through Friday. T he applicant shall provide hotel vouchers if earplugs and white noise machines are not sufficient, as requested by effected residents prior to commencement of excessively noisy nighttime work or within 24 hours of receiving a complaint.  ( The importance of the services provided by the facility creating the noise and the other impacts caused to the public safety, health and welfare balanced against the harm to be suffered by residents or property owners receiving the increased noise permitted under this variance. Staff Comment: According to the applicant, both SR 515 and SR 167 are major parts of the transportation system of the Puget Sound area and the night work proposed is necessary to complete its funded improvement. WSDOT contends that the nighttime work would not cause impacts to the public safety, health and welfare and no harm would be suffered by the residences or properties due to the temporary increase over the 47 dBA permitted under the City of Renton Code. Staff concurs with the applicant that the proposed maintenance project is necessary to address capacity and mobility improvements to the public and users. The project benefits outweigh the limited-term noise impacts to residents and property owners and the applicant has identified specific project measures to be implemented to reduce or eliminate excessive noise.  ( The availability of practicable alternative locations or methods for the proposed use which will generate the noise. Staff Comment: The applicant contends that rehabilitation of existing highway infrastructure is a challenge because construction has to occur at locations where significant traffic volumes are present. Furthermore, if the work occurs during the daytime, there are additional impacts such as extending the life of the project and affecting the public for longer periods of time. The applicant further contends that working at night would allow WSDOT to limit impacts to the traveling public, bus service, and nearby businesses. Lastly, performing the work at night minimizes the danger to workers and the traveling public from road closures, detours and traffic delays. To mitigate those impacts from night work, WSDOT has been working and would continue to work with City of Renton staff and the community to minimize project impacts. No alternative locations are possible.  ( The extent by which the prescribed noise limitations will be exceeded by the variance and the extent and duration of the variance. Staff Comment: Noise levels produced by construction equipment is expected to range from 61 to 97 dBA at a distance of 50 feet (50’) from the source of the noise. These sound levels are expected to diminish to a range of 45 to 81 dBA at a distance of 300 feet (300’) from the source of the noise. The applicant is requesting a total of 15 cumulative nights including some contingency.   CONCLUSIONS: The applicant, Washington State Department of Transportation (WSDOT), requested a noise variance in order to exceed the nighttime dBA limits for all EDNA properties along the NWR South 23 – 25 Pavement Repair Project XL6747 within Renton City Limits. The proposed noise variance meets the seven (7) criteria to be considered in making a decision on a variance request as specified by RMC 8-7-8.D, if all conditions of approval are met. The analysis of the proposal, according to noise variance criteria, is found in the body of the Staff Report, see FOF 9. H.
