proposed Harmony Ridge residential development located at 15509 116th Ave SE in Renton, WA. Project Proposal. The proposed Harmony Ridge residential development includes 21 new single- family detached housing units on a site currently occupied by 3 existing church/school buildings utilized by the United Christian Church, all of which will remain with the project. Vehicular access to/from the proposed residential development would be provided by a new public road and intersection onto 116th Ave SE located just south of the existing church/school driveways. Full buildout of the project is expected in 2024. Trip Generation. The proposed project is estimated to generate 240 new weekday daily trips, with 18 new trips occurring during the weekday AM peak hour (5 in, 13 out), and 23 new trips occurring during the weekday PM peak hour (14 in, 9 out). Future Year LOS. LOS analyses were conducted for future year 2024 weekday PM peak hour conditions at six (6) off-site study intersections. All study intersections, including all controlled movements at the stop-controlled study intersections, are expected to operate at LOS D or better during the weekday PM peak hours in 2024 with or without the proposed project. The Transportation Element of the City’s Comprehensive Plan specifies a minimum standard of LOS D for arterials and collectors. Site Access Analysis. All turn movements entering and exiting the proposed site access intersection onto 116th Ave SE are expected to operate at LOS B or better during the weekday PM peak hour in 2024 with 95th percentile queues anticipated to be less than 25 feet. Mitigation. Off-Site Improvements. Based on the results of the analysis, the existing transportation facilities are anticipated to accommodate the additional traffic generated by the proposed project. No project-specific off-site transportation improvements are proposed. Transportation Impact Fees. To mitigate long-term traffic impacts, the City of Renton requires payment of a traffic impact fee. The City’s currently adopted 2021-2022 impact fee rate is $10,861.69 per single-family detached dwelling unit. Final transportation impact fees will be paid based on the current impact fee rate at the time of building permit issuance less any applicable transportation impact fee credit.

Estimated daily volumes are based on 2022 PM volumes and a K-factor of 10. 2 MEV = Million Entering Vehicles for Intersections. Intersection collision rates over 1.0 collision per MEV generally warrant further review to determine if any patterns exist. Based on the collision data, none of the study intersections have a rate that exceeds 1.0 collision per MEV. Existing PM Peak Hour Traffic Volumes Existing (2022) weekday PM peak hour traffic volumes at the study intersections were based on turning movement counts collected by All Traffic Data in November 2022. The existing PM peak hour traffic volumes represent the highest one hour of traffic between 4:00 and 6:00 PM. Figure 3 illustrate the 2022 existing PM peak hour traffic volumes at the study intersections. Detailed peak hour turning movement count sheets are provided in Appendix A.

LOS generally refers to the degree of congestion on a roadway or intersection. It is a measure of vehicle operating speed, travel time, travel delays, and driving comfort. A letter scale from A to F generally describes intersection LOS. At signalized intersections, LOS A represents free-flow conditions (motorists experience little or no delays), and LOS F represents forced-flow conditions where motorists experience an average delay in excess of 80 seconds per vehicle. The LOS reported for signalized intersections represents the average control delay (sec/veh) and can be reported for the overall intersection, for each approach, and for each lane group (additional v/c ratio criteria apply to lane group LOS only). The LOS reported at stop-controlled intersections is based on the average control delay and can be reported for each controlled minor approach, controlled minor lane group, and controlled major- street movement (and for the overall intersection at all-way stop controlled intersections. Additional v/c ratio criteria apply to lane group or movement LOS only). Table 3 outlines the current HCM 6th Edition LOS criteria for signalized and stop-controlled intersections based on these methodologies. Table 3 LOS Criteria for Signalized and Stop-Controlled Intersections1 SIGNALIZED INTERSECTIONS STOP-CONTROLLED INTERSECTIONS LOS by Volume-to Capacity (V/C) Ratio2 LOS by Volume-to Capacity (V/C) Ratio3 Control Delay (sec/veh) 1.0 > 1.0 Control Delay (sec/veh) 1.0 > 1.0  10 A F  10 A F > 10 to  20 B F > 10 to  15 B F > 20 to  35 C F > 15 to  25 C F > 35 to  55 D F > 25 to  35 D F > 55 to  80 E F > 35 to  50 E F > 80 F F > 50 F F 1 Source: Highway Capacity Manual (6th Edition), Transportation Research Board, 2016. 2 For approach-based and intersection-wide assessments at signals, LOS is defined solely by control delay. 3 For two-way stop controlled intersections, the LOS criteria apply to each lane on a given approach and to each approach on the minor street. LOS is not calculated for major-street approaches or for the intersection as a whole at two-way stop controlled intersections. For approach-based and intersection-wide assessments at all-way stop controlled intersections, LOS is solely defined by control delay. Level of service calculations for the study intersection was based on methodology and procedures outlined in the latest Highway Capacity Manual (6th Edition) using Synchro 11 traffic analysis software. Existing signal timing used in the analysis was provided by the City of Renton. The 2022 existing weekday PM peak hour LOS analysis results for the off-site study intersections are summarized in Table 4. The 2022 existing detailed LOS worksheets are included in Appendix B.
