APPLICABLE SECTIONS OF THE RENTON MUNICIPAL CODE: 1. Title VIII, Chapter 7 Noise Level Regulations G. PROJECT DESCRIPTION/BACKGROUND: The applicant, City of Renton Public Works Department Transportation Design Engineering Division (“Transportation Division”), is requesting a noise variance from RMC 8-7-2 (Noise Level Regulations, Maximum Environmental Noise Levels) to work during night and weekend hours beyond the days and hours permitted in Renton Municipal Code (RMC) 4-4-030 to complete construction on the Rainier Ave S Corridor Improvements – Phase 4 project (Exhibits 3-15). The proposed nighttime repair work would be along Rainier Ave S from S 3rd St to NW 3rd Pl (Exhibit 2). The project would include sidewalk widening with streetscaping, pedestrian-scale lighting, pedestrian activated traffic signal, upgrading existing traffic signals, transit improvements, planted buffer strips and landscaped medians. The project goals include the following: • Improve transit mobility, pedestrian accessibility, and safety. • Benefits overall traffic flow and safety through access management, traffic signal upgrades and coordination. • Improve the pedestrian environment and safety resulting in an aesthetically vibrant transportation corridor. • Intersection improvements at S 3rd St and S 2nd St in preparation of the two-way conversion. • Extend the southbound Business Access Transit Lane (BAT Lane) from S 2nd St to S 3rd St. • Construction of a segment of a regional pedestrian/bike path trail (Lake Washington Loop Trail) from Airport Way to 1,000 feet north of Airport Way. • Installation of pedestrian activated traffic signals (HAWK) at SW Victoria St and NW 3rd Pl. • Sidewalk widening and streetscaping, decorative roadway and pedestrian-scale illumination, landscaped buffers and medians. Approximately 500 non-consecutive working days of nighttime work would be required between now and the completion of the project, currently anticipated to be February 2025 (Exhibit 21). The primary reason for conducting nighttime work is to lessen daytime traffic congestion along Rainier Ave S corridor. Noise levels City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 4 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 resulting from project construction activities are expected to generate peak noise levels of 61 to 92 dBA heard at 50 feet from the source of the noise. These sound levels are expected to diminish to a range of 45 to 76 decibels at a distance of 300 feet from the source of the noise. A variance from RMC 8-7-2 is necessary in order to conduct the nighttime work, as maximum permissible environmental noise levels (per WAC 173- 60-040, incorporated by reference in RMC 8-7) limit extended periods of noise from 10:00 pm to 7:00 am to levels between 45 dBA and 60 dBA, with exceedances of 5 to 15 dBA permitted for periods of 1.5 to 15 minutes in any one-hour period (WAC 173-60-040). Some of the noisiest pieces of equipment that would be utilized include an excavator, generator, backhoe, concrete saw, fork lift, jackhammer, compactor (roller), and vacuum truck. H. FINDINGS OF FACT (FOF): 1. The Planning Division of the City of Renton accepted the above master application for review on July 19, 2023 and determined the application complete on July 25, 2023. The project complies with the 120-day review period. 2. The project site is located along Rainier Ave S, approximately 0.6 linear miles from S 3rd St to NW 3rd Pl. 3. The roadway improvement project site is currently developed as right-of-way. 4. The site is mapped with high erosion hazards, moderate landslide hazards, regulated slopes, high seismic hazards, and is located in the downtown wellhead protection area zone 2. 5. The applicant began project mobilization on March 3, 2023 (Exhibit 21). The construction duration is anticipated to finish on February 26, 2025 following channelization and striping work. 6. Staff received one (1) public comment email on August 4, 2023 (Exhibit 19) and staff responded to the public comment received on August 8, 2023 (Exhibit 20). To further address public comments the following report contains analysis related to construction hours and nighttime noise impacts. 7. No other public or agency comments were received. 8. 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. 9. Variance Analysis: The City’s Transportation Division is requesting a noise variance from RMC 8-7-2 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  a. 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: Renton’s Transportation Division is requesting a noise variance to complete night work on the Rainier Ave S Corridor Improvement Project – Phase 4 from S 3rd St to NW 3rd Pl. According to the applicant, Rainier Ave S corridor is a principal arterial that carries 42,000 ADT (Average Daily Traffic) and the purpose of the project is to address capacity and mobility improvements to the public and users (Exhibit 18). In addition, the applicant contends that Rainier Ave S serves as a key connector for commercial, freight, City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 5 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 motorist uses, and mass transit within the City of Renton. Daytime extended lane closures, full or partial, to perform the work would have the potential to worsen the already congested corridor. The project representative on the Rainier Ave S Corridor Improvement – Phase 4 project is Pivetta Brother’s Construction, Inc. According to the applicant, the project representative would be required 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. The applicant contends that in order to meet these requirements, it is necessary that some of the work for this project be done at night. The applicant further maintains that work at night is the best way to minimize negative effects as a result of construction which would only exacerbate the existing traffic conditions. The requested noise variance would allow for temporary exceedance of noise level limits during the nighttime hours (between 10:00 pm and 7:00 am) which is expected to improve safety for drivers and construction workers when some of the work is done at night and this 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 proposed to complete the work include the following: a boom truck with auger, 330 hoe- pac, 350/650/750 excavators, 75 KW generator, 935/966 front loaders, air automatized stripe grinder, backhoe, boom truck with auger, compactor (roller), concrete saw, dump/haul truck, excavator cat 349 with breaker, fork lift, jackhammers, light plants, paver and slip form, planning grinder/milling machine, skid steer, sweeper, vacuum truck, vibrator concrete consolidator, and water trucks (Exhibit 16). Staff concurs with the applicant that the location of the work within the Rainier Ave S corridor is one of the most heavily travelled roads in Renton. Therefore, the variance is necessary because of the special circumstances applicable to the Rainier Ave S corridor. The City Transportation Division would continue to work with Pivetta Brother’s Construction, Inc. 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 finish the project quicker and limit the impacts on the community and improve safety for drivers and construction workers.  b. 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 temporary nighttime construction is one of the few tools that Renton is able to employ to lessen traffic congestion and disruption to roadway users while improving the roadway. In general, the applicant contends that the sound generated from the construction work, such as the construction equipment, as it propagates over distance would be as follows: a 6-dBA noise level decrease with every doubling of the distance from a stationary noise source. For example, a noise level of 70 dBA measured at 50 feet would be 64 dBA at 100 feet, 58 dBA at 200 feet and 52 dBA at 400 feet. In addition, noise also decreases if an object interferes with the receiver’s line of sight to the noise source as well as with a topographic interference either natural like a hill or a man-made berm. For example, the applicant contends the following points: City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 6 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 a. Residents are staggered out at several locations with different topographic features and how residents perceive the night time construction sounds from the project would vary; b. When distance and topography are incorporated into the assessment, along with the proposed mitigation measures, how much residents perceive or not perceive the nighttime construction noise would depend on the item of work and where the work takes place; and c. The monitoring plan developed would address all the impacts to residents that would be impacted to minimize any possibility that the public health or safety would be diminished. If any noise related complaints are received, the contractor along with the agency would work on alternative mitigation measures to stop the inconvenience including providing hotel vouchers or identify state of the art measures currently in the market to minimize the impacts. Noise levels projected for this project have been estimated between 61 to 92 dBA heard at 50 feet from the source of the noise. These sound levels are expected to diminish to a range of 45 to 76 decibels at a distance of 300 feet from the source. The applicant concludes that construction equipment sounds would likely be noticeable by residents during nighttime operations if they have direct line of sight. The applicant is proposing several noise mitigations measures to lower the risk of any noise noticed by residents. For example, the applicant is proposing an after-hour noise complaint phone number would be available (Exhibit 16) and hotel accommodations if the noise proves too much for adjoining property owners (Exhibit 17). See subsection ‘d’ for discussion 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 included a multi-approach condition under subsection ‘d’ that would allow staff and the applicant to address complaints from residents in the vicinity of the work area.  c. 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 Pivetta Brother’s Construction, Inc. to accomplish this work in the minimum number of nights required to complete all the work along Rainier Ave S, as shown on the Neighborhood Detail Map and Bid Documents (Exhibits 2-15). This request includes up to 500 non-consecutive nights in total, including contingency. Staff concurs with the applicant that the approval is the minimum variance that would accomplish the desired purpose. Noise mitigation measures are proposed by the applicant to diminish the impact on affected properties as much as possible in Renton along the Rainier Ave S corridor from S 3rd St to NW 3rd Pl. Compliant if All Conditions of Approval are Met d. 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; City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 7 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 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; 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. Staff Comment: Renton Transportation Division provided a noise variance justification response (Exhibit 18) and mitigation measures in the project narrative (Exhibit 17) to follow RMC 8-7-8.D.4, Factors For Granting Variance, and are detailed below (Renton Transportation Division’s responses are underlined): a. Implementation of a noise monitoring program; Would only perform nighttime noise monitoring if a confirmed complaint is received. b. Maximum noise levels; Noise levels projected for this project have been estimated to generate peak noise levels of 61 to 92 dBA heard at 50 feet. Background traffic noise levels on Rainier Ave S reach approximate average noise levels up to 71 dBA during the daytime at 50 feet from the travel lane with a reduction to 66 dBA due to lower average traffic at night. c. Limitation on types of equipment and use of particular equipment; Not applicable. d. Limitation on back-up beepers for equipment; All alarms would operate under OSHA and L&I rules and regulations and WAC and RCW. e. Required use of noise shields or barriers; Mitigation measures would include the use of acoustic noise blankets, or other means available for noise shielding as approved by the Engineer if installation within the work zone is feasible and they are not a safety risk to roadway users and workers. f. Restrictions to specific times and days; Night work would occur Monday thru Thursday night with a current expiration date of February 26, 2025. g. Specific requirements for documentation of compliance with the noise variance conditions; The City’s project team would receive training and update of the conditions under which this variance was granted. The City’s project team would implement a nighttime noise City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 8 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 monitoring process if complaints are received. Monitoring reports would be made available to the city to demonstrate compliance. h. Specific requirements for notification to nearby residents; The City’s project team would notify by US mail residents within 300 feet of the site. This notification would include the type of work, as well as phone number or email to request more information including specific requests or concerns. i. Required cash security to pay for inspection services to verify compliance; The City’s Transportation Division would pay for inspection services as required. j. Required access to the project by the City to verify compliance with the noise variance conditions; The City’s Transportation Division would grant site access to other City staff as required. k. Specific program to allow for temporary hotel vouchers to effected residents; The City’s Transportation Division would provide hotel vouchers if earplugs and white noise machines are not sufficient, as requested by effected residents. l. Requirements for written verification that all workers understand the noise variance conditions for the project; Pivetta Brother’s Construction, Inc. would provide the city with an attendance sheet of workers that would participate in night work. m. Provision allowing the City to immediately revoke the variance approval if the variance conditions are violated; The City’s project team understands that the City may revoke the variance if conditions are violated. According to the applicant’s noise study submitted with the application, the applicant would utilize a number of these suggested mitigation measures and monitoring techniques in order to help limit impacts on EDNA properties along the Rainier Ave S project corridor. For example, all alarms for equipment would operate under Occupational Safety and Health Administration (OSHA) standards, Labor & Industries (L&I) rules and regulations, Washington Administrative Code (WAC) regulations, and the Revised Code of Washington (RCW) laws. Not all of the suggested mitigation measures under RMC 8-7-8.D.4 were found necessary to minimize the project’s noise impacts and several can be considered code enforcement and inspection tool designed to facilitate staff oversight of the project. Based on the suggested mitigation measures addressed above, the applicant has proposed effective mitigation measures that would limit the impacts on the EDNA properties. In order to ensure complaints or issues submitted by residents are adequately addressed, staff recommends, as a condition of approval, that the applicant and the contractor implement the noise mitigation measures (listed above) for granting a variance to diminish or eliminate noise during the Rainier Ave S Corridor Improvement project. Complaints shall be addressed within 24 hours or one business day. In addition, a summary of any noise-related complaints received and the response provided shall be provided to the City’s project manager within one week of receiving the complaint. In addition, staff recommends, as a condition of approval, that the applicant post an after hour noise complaint phone number and all scheduled nighttime work planned on the transportation systems – projects and programs webpage ( City of Renton Department of Community & Economic Development Rainier Ave S Corridor Improvements: Phase 4 Staff Report to the Hearing Examiner LUA23-000241, V-H Report of September 12, 2023 Page 9 of 10 SR_Rainier_Ave_S_Corridor_Improvements_Phase4_Noise_Variance_230912_v11 https://www.rentonwa.gov/city_hall/public_works/transportation_systems/projects_and _programs/current_projects/rainier_ave_s_phase_4_-_s_3rd_st_to_n_w_3rd_pl) so residents have digital access to when and where the nighttime work would occur along the corridor and where to provide complaints.  e. 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, Rainier Ave S is a major part of the transportation system in Renton and the night work proposed is necessary to complete its funded improvement authorized by the State Legislature. In addition, the applicant 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 Rainier Ave S Corridor Improvements – Phase 4 project is necessary to improve transit mobility, pedestrian accessibility, pedestrian environment, and safety to the public and users. In addition, the variance is critical to helping the applicant lessen daytime traffic congestion along Rainier Ave S corridor. On balance, the project benefits outweigh the limited-term noise impacts to residents and property owners given the applicant has identified and proposed specific project measures to be implemented to reduce or eliminate excessive noise.  f. The availability of practicable alternative locations or methods for the proposed use which will generate the noise. Staff Comment: The applicant contends that reconstruction of existing roadway to adapt to more current design that meets the City plan is a challenge because construction has to occur at locations where longtime residents reside. Furthermore, if some of the work occurs during the day time there are additional consequences, 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 is the only option that would allow the use of additional lane closures which would help to alleviate construction impacts. To mitigate those impacts from night work, the project team has been working and would continue to work with City of Renton staff and the community to minimize project impacts. The roadway improvements are a fixed location and no alternative locations for the project are possible.  g. The extent by which the prescribed noise limitations will be exceeded by the variance and the extent and duration of the variance. Staff Comment: The noise levels produced by construction equipment is expected to range from 61 to 92 dBA at a distance of 50 feet from the source of the noise. These sound levels are expected to diminish to a range of 45 to 76 dBA at a distance of 300 feet from the source of the noise. The applicant is requesting a total of 500 non-consecutive nights, including some contingency nights to complete the work. Furthermore, the applicant contends that noise levels would not be concentrated at one location for more than two (2) weeks at a time and not all sounds created by the project would be equally bothersome. Overall, the extent and duration of noise impacts are not anticipated to be significant.
