Renton TENW April 24, 2019 Page 1 FINDINGS/CONCLUSIONS This traffic impact analysis (TIA) has been prepared for the proposed Canopy Residential development located at 4196 Lincoln Place NE in Renton, WA. Project Proposal. The proposed Canopy Residential development would include up to 56 single-family dwelling units on a site that currently includes two single-family dwelling units which would be demolished with the proposed project. Vehicular access to the Canopy Residential development would be provided via a new full access onto Lincoln Ave NE and a new full access on NE 40th Street that will be accessed through the intersection of Monterey Pl NE/NE 40th Street. Full buildout of the project is estimated to occur in 2021. Trip Generation. The proposed Canopy Residential project is estimated to generate 591 net new weekday daily trips, with 44 net new trips occurring during the weekday AM peak hour (11 in, 33 out), and 56 net new trips occurring during the weekday PM peak hour (36 in, 20 out). Future Year LOS. LOS analyses were conducted for future year 2021 weekday AM and PM peak hour conditions at two off-site study intersections. Based on the analysis results, the SB left-through movement at the stop-controlled intersection of the I-405 SB Ramps/NE 44th Street is anticipated to operate at LOS F under weekday AM and PM peak hour conditions in 2021 without or with the proposed project. All other controlled movements at I-405 SB Ramps/NE 44th Street are anticipated to operate at LOS B or better during the AM and PM peak hours in 2021 without or with the proposed project. Additionally, the all-way stop controlled intersection of the I-405 NB Ramps/NE 44th Street is anticipated to operate at LOS F during the AM and PM peak hours in 2021 without or with the proposed project. Sound Transit and WSDOT have identified planned improvements at the two study intersections as part of the WSDOT I-405 Renton to Bellevue Widening and Express Toll Lanes project and Sound Transit 3Ês I-405 Bus Rapid Transit (BRT) project. The planned improvements include roundabouts at these two study intersections that will improve future operations. Site Access LOS and Queuing. LOS and queue analyses were conducted for future year 2021 weekday AM and PM peak hour conditions at the two proposed site access locations. All controlled movements at the unsignalized site access on Lincoln Ave NE and at the intersection of Monterey Pl NE/NE 40th Street (site access) are expected to operate at LOS B or better with 95th percentile queues of no more than 1 vehicle during the AM and PM peak hours. Site Access Sight Distance Evaluation. Intersection sight distance (ISD) and stopping sight distance (SSD) were evaluated at the location of the proposed site access on Lincoln Ave NE and also at the intersection of Monterey Place NE/NE 40th Street (providing access to the site). Both ISD and SSD were met at the proposed site access on Lincoln Ave NE. At the Monterey Place/NE 40th Street intersection, ISD is not met looking to the north. As a result, turn restrictions may be necessary to limit left-turns from NE 40th Street onto Monterey Place NE. Mitigation. Transportation mitigation required by the City of Renton is payment of a transportation impact fee. As of the date of this study, the adopted City of Renton 2019-2020 impact fee schedule identifies a 2019 fee of $7,820.42 per single-family dwelling unit. The proposed 56 single-family unit Canopy Residential development, less removal of the two existing single family units, would have an estimated transportation impact fee of $422,302.68 ($7,820.42 X 54 net new single-family dwelling units). DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 2 INTRODUCTION This traffic impact analysis (TIA) has been prepared for the proposed Canopy Residential development located at 4196 Lincoln Place NE in Renton, WA as shown in the Figure 1 vicinity map. Project Description The proposed Canopy Residential development would include the development of up to 56 single- family dwelling units on a site that currently includes two single-family dwelling units which would be demolished with the proposed project. Vehicular access to the Canopy Residential development would be provided via a new full access onto Lincoln Ave NE and a new full access on NE 40th Street that will be accessed through the intersection of Monterey Pl NE/NE 40th Street. Full buildout of the project is estimated to occur in 2021. A preliminary site plan is provided in Figure 2. Project Approach To analyze the traffic impacts from the project, the following tasks were undertaken: · Assessed existing conditions through field reconnaissance and reviewed existing planning documents; · Described and assessed existing transportation conditions in the area; · Documented planned transportation improvements in the site vicinity; · Documented existing traffic volumes and intersection levels of service (LOS) at the following two study intersections during the weekday AM and PM peak hours: 1. I-405 Southbound (SB) Ramps / NE 44th Street (stop-controlled SB) 2. I-405 Northbound (NB) Ramps / Lake Washington Boulevard NE / NE 44th Street (all-way stop) · Documented collision history at study intersections; · Estimated trip generation and documented trip distribution and assignment of AM and PM peak hour project-generated traffic; · Documented traffic forecasts and assumptions for year 2021 conditions at the two study intersections without and with the proposed development; · Analyzed weekday AM and PM peak hour LOS for year 2021 conditions at the two study intersections without and with the proposed development; · Analyzed weekday AM and PM peak hour LOS and queuing for year 2021 conditions with the project at the proposed site access; · Evaluated entering and stopping sight distance at the proposed site access on Lincoln Ave NE and at NE 40th Street/Monterey Pl NE per WSDOT Design Manual standards; · Identified transportation mitigation to the City of Renton.

Non-Motorized Transportation Facilities Pedestrian facilities in the immediate project vicinity are limited. Paved shoulders exist on both sides of Lincoln Ave NE. Sidewalks exist on NE 44th Street, north of the project site. Transit Service There is no nearby transit service in the project vicinity. Existing Traffic Volumes Existing weekday AM and PM peak hour traffic volumes at the two study intersections were based on counts conducted by All Traffic Data in June 2018. Year 2019 traffic volumes were estimated by applying a 2 percent annual growth rate to the 2018 traffic volumes. Figure 3 illustrates the 2019 existing weekday AM and PM peak hour traffic volumes at the study intersections. The detailed peak hour turning movement count sheets are provided in Appendix A. DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 7 Figure 3 2019 Existing Weekday Peak Hour Traffic Volumes DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 8 Level of Service Weekday AM and PM peak hour level of service (LOS) analyses were conducted at the following study intersections: 1. I-405 Southbound (SB) Ramps / NE 44th Street (unsignalized, SB stop-control) 2. I-405 Northbound (NB) Ramps / Lake Washington Boulevard NE / NE 44th Street (unsignalized all-way stop) The LOS analyses were based on methodologies and procedures outlined in the Highway Capacity Manual (HCM 6th Edition). LOS serves as an indicator of the quality of traffic flow and degree of congestion at an intersection or roadway segment. It is a measure of vehicle operating speed, travel time, travel delays, and driving comfort. The LOS methodology is described in Appendix B. The Synchro Version 10.3 software package was used to determine LOS results. The 2019 existing AM and PM peak hour LOS analysis results for the study intersections are summarized in Table 2. The LOS worksheets are included in Appendix C. Table 2 2019 Existing Peak Hour LOS Summary AM Peak Hour PM Peak Hour Study Intersection / Movement LOS Delay (sec) LOS Delay (sec) Two-Way Stop Controlled Intersection 1.

DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 10 FUTURE TRAFFIC CONDITIONS AND PROJECT IMPACTS Planned Transportation Improvements Based on a review of the City of RentonÊs adopted 2019-2024 Transportation Improvement Program (TIP), there are no planned transportation improvement projects within the project vicinity. Improvements at the I-405/NE 44th Street interchange are planned as part of the Washington State Department of Transportation (WSDOT) I-405 Renton to Bellevue Widening and Express Toll Lanes project and Sound Transit 3Ês I-405 Bus Rapid Transit (BRT) project. Current plans for the I-405/NE 44th Street interchange include new direct access ramps, reconstruction of the northbound access ramp to I-405 from a loop ramp to a new on-ramp from Lake Washington Blvd NE, four new roundabouts along local arterials, a new BRT station in the I-405 median, and a new 200-stall park-and-ride at Lake Washington Blvd N/N 43rd Street. The project is anticipated to be complete in 2024. Project Trip Generation The trip generation estimates for the proposed Canopy Residential project (up to 56 single-family lots) were based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th edition for land use code (LUC) 210 (Single-Family Detached Housing). Table 5 summarizes the resulting new weekday daily, AM peak hour, and PM peak hour trip generation estimates for 54 net new single-family homes (56 proposed single-family homes less 2 existing single-family homes). Detailed trip generation calculations are included in Appendix D. DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 11 Table 5 Trip Generation Summary Net New Trips Generated Weekday Time Period In Out Total Daily 296 295 591 AM Peak Hour 11 33 44 PM Peak Hour 36 20 56 As shown in Table 5, the proposed Canopy Residential project is estimated to generate 591 net new weekday daily trips, with 44 net new trips occurring during the weekday AM peak hour (11 in, 33 out), and 56 net new trips occurring during the weekday PM peak hour (36 in, 20 out). Project Trip Distribution and Assignment The distribution of the new project trips generated by the proposed Canopy Residential project was based on existing travel patterns in the area. The following Table 6 summarizes the resulting general trip distribution patterns. The distribution of project trips is shown graphically in Figure 4. Table 6 Project Trip Distribution Route (Direction) Trip Distribution I-405 (north) 35% I-405 (south) 40% Lake Washington Blvd NE (North) 15% Monterey Pl NE (south) 10% TOTAL 100% Based on the trip distribution percentages, the net new weekday AM and PM peak hour project trips were assigned through the study intersections. The resulting assignment of the net new AM and PM peak hour project trips through the two study intersections is shown in Figure 4. Future Traffic Volumes The project is anticipated to be fully constructed and occupied in 2021. To estimate the future year 2021 Without Project traffic volumes at the two study intersections, a 2 percent annual growth rate was applied to the existing traffic volumes, as directed by City staff. This growth factor is used to account for new development in the study area and growth in existing traffic. The resulting future 2021 Without Project AM and PM peak hour traffic volumes are shown in Figure 5. The 2021 With Project traffic volumes were determined by adding the trip assignment from the proposed development (shown in Figure 4) to the future 2021 Without Project traffic volumes. The resulting future 2021 With Project AM and PM peak hour traffic volumes at the two study intersections are shown in Figure 6.

All other controlled movements at I-405 SB Ramps/NE 44th Street are anticipated to operate at LOS B or better during the AM and PM peak hours in 2021 without or with the proposed project. Additionally, the all-way stop controlled intersection of the I-405 NB Ramps/NE 44th Street is anticipated to operate at LOS F during the weekday AM and PM peak hours in 2021 without or with the proposed project. Sound Transit and WSDOT have identified planned improvements at the two study intersections as part of the WSDOT I-405 Renton to Bellevue Widening and Express Toll Lanes project and Sound Transit 3Ês I-405 Bus Rapid Transit (BRT) project. The planned improvements include roundabouts at the two study intersections that will improve future operations at these intersections. DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 16 Site Access Analysis Vehicle access for the Canopy Residential development is proposed to be provided via a new full access on Lincoln Ave NE and a new full access on NE 40th Street that would be accessed via the existing intersection of Monterey Place NE/NE 40th Street. LOS and Queue Results at Site Access Future year 2021 With-Project AM and PM peak hour level of service (LOS) and queue analyses was conducted at the proposed site access based on the methodology and procedures outlined in the 6th Edition of the Highway Capacity Manual (HCM) using the Synchro 10.3 software program. The reported queues for the controlled movements at the unsignalized site access are 95th percentile queues. The estimated 95th percentile queues are exceeded only 5 percent of the time during the analysis period. The 2021 With Project AM and PM peak hour volumes at the site access as used in the LOS and queue analyses are as shown on Figure 6. The weekday AM and PM peak hour LOS and queue results at the site access for 2021 With-Project conditions are summarized in Table 8. The LOS and queue worksheets are included in Appendix C. Table 8 Year 2021 Peak Hour Level of Service Summary at Site Access 2021 With-Project AM Peak Hour 2021 With-Project PM Peak Hour Site Access and Movement LOS Delay (sec) Queue Length (veh)1 LOS Delay (sec) Queue Length (veh)1 Stop Controlled Intersections A.

Queues are 95th Percentile queues. < 1 vehicle indicates 95th Percentile queue statistically less than 1 vehicle. As shown in Table 8, all controlled movements at the unsignalized site access on Lincoln Ave NE and at the intersection of Monterey Pl NE/NE 40th Street (site access) are expected to operate at LOS B or better with 95th percentile queues of less than 1 vehicle during the AM and PM peak hours. Sight Distance Assessment at Proposed Site Access Intersection sight distance (ISD), also called entering sight distance, and stopping sight distance (SSD) were evaluated at the location of the proposed site access on Lincoln Ave NE and also at the DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 17 intersection of Monterey Place NE/NE 40th Street since the southern site access is proposed on NE 40th Street. The City of Renton does not have jurisdiction specific requirements related to sight distance. Based on historical precedence in the City of Renton, this project proposes to use WSDOT sight distance standards for roadway, intersection, and driveway design. WSDOTÊs current best practices related to sight distance are to use a design speed equal to the posted speed/desired operating (target) speed. WSDOT found that vehicles tend to travel at the rate in which the roadway was designed to which led to their current policy. WSDOT has concluded that adding an additional margin above the posted speed (such as +5mph or +10mph) can lead to increased operating speeds which is undesirable. Therefore, WSDOT current practice uses a design speed equal to the posted speed for designing roadway elements such as sight distance, horizontal/vertical geometry, etc. Based on the existing 25 mph posted speed limit on Lincoln Ave NE and Monterey Place NE, a design speed of 25 mph was used in this sight distance analyses. Intersection Sight Distance (ISD) Intersection (aka entering) sight distance was evaluated at the two proposed project access locations. ISD measurements were based on the November 2015 edition of the Washington State Department of Transportation (WSDOT) Design Manual Chapter 1310.05 Intersection Sight Distance. The setback distance from the intersection sight distance sight triangle is 18 feet from the edge of traveled way, 3.5 feet above the road surface, looking at an object 3.5 feet above the road surface. Proposed Site Access on Lincoln Ave NE: Based on a 25 mph design speed on Lincoln Ave NE, the desirable ISD for turning vehicles is 280 feet. At the proposed site access on Lincoln Ave NE, the available ISD looking to the north and south on Lincoln Ave NE was verified to exceed the recommended design value of 280 feet (therefore meeting City standards); this assumes existing vegetation in the sight triangles will be cleared and no sight obstructions will be placed in the sight triangles with the project. A detailed sight distance exhibit is included in Appendix E. Sight Distance Triangles at Proposed Site Access on Lincoln Ave NE Proposed Access at NE 40th Street/Monterey Place NE: Based on a 25 mph design speed on Monterey Place NE, the desirable intersection sight distance for turning vehicles is 280 feet. The setback distance for the intersection sight distance sight triangle was reduced from 18 feet to 10 feet per WSDOT Design Manual 1310.05 when there are existing sight obstructions. DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 18 The available ISD looking to the south on Monterey Place NE from NE 40th Street was verified to be in excess of the recommended design value (280 feet) therefore meeting City standards. However, the measured ISD looking to the north on Monterey Place NE from NE 40th Street does not meet the recommended design value of 280 feet since the sight triangle for vehicles looking to the north on Monterey Place NE from NE 40th Street includes sight-line obstructions (existing trees and shrubbery/vegetation). Turn restriction may be necessary to limit left-turns from NE 40th Street onto Monterey Place due to this deficiency. A detailed sight distance exhibit is included in Appendix E. Sight Distance Triangles at NE 40th St / Monterey Pl NE Stopping Sight Distance Stopping sight distance (SSD) standards were based on the July 2016 edition of the WSDOT Design Manual Chapter 1260.03 Stopping Sight Distance. WSDOT standards use a driverÊs eye height of 3.5 feet, and an object height of 2.0 feet. Proposed Site Access on Lincoln Ave: Based on a 25 mph design speed and a -3% downgrade in the northbound direction and a +6% upgrade in the southbound direction on Lincoln Ave NE, the recommended design value for SSD based on WSDOT Design Manual standards is 158 feet in the northbound direction and 143 feet in the southbound direction. Approaching the proposed site access on Lincoln Ave NE from the north and south, the available SSD was verified to be in excess of the recommended design values, therefore meeting City standards. Proposed Access at NE 40th Street/Monterey Place NE: Based on a 25 mph design speed and a -6% downgrade in the northbound direction and a +6% upgrade in the southbound direction on Monterey Place NE, the recommended design value for SSD based on WSDOT Design Manual standards is 165 feet in the northbound direction and 143 feet in the southbound direction. Approaching the Monterey Place NE intersection with NE 40th Street from the north and south, the available stopping sight distance was verified to be in excess of the recommended design values, therefore meeting City standards. DRAFT Traffic Impact Analysis Canopy Residential - Renton TENW April 24, 2019 Page 19 MITIGATION Transportation mitigation required by the City of Renton is payment of a transportation impact fee. The proposed Canopy Residential development would include the development of up to 56 single family dwelling units on an existing site that currently includes two single family dwelling units that would be removed as part of the proposed project. As of the date of this study, the adopted City of Renton 2019-2020 impact fee schedule identifies a 2019 fee of $7,820.42 per single-family dwelling unit.

Renton Appendix B Level of Service (LOS) Methodology DRAFT Traffic Impact Analysis Canopy Residential - Renton Level of Service Methodology Level of service calculations for intersections were based on methodology and procedures outlined in the 2016 update of the Highway Capacity Manual, Transportation Research Board (HCM 6th Edition) using Synchro 10.3 traffic analysis software. 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 B1 outlines the current HCM LOS criteria for signalized and stop-controlled intersections based on these methodologies. Table B1 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, 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.
