TENW Transportation Engineering NorthWest Transportation Planning I Design I Traffic Impact & Operations PO Box 65254, Seattle, WA 98155I Office (206) 361-7333 MEMORANDUM DATE: June 21, 2016 TO: Min Luo, Senior Engineer, City of Redmond FROM: Michael J Read, P.E., Principal, TENW SUBJECT: Phase II Traffic Impact Analysis Redmond Town Center Apartments – Redmond, WA – TENW Project No. 3428 This memorandum documents the Phase II traffic impact analysis completed for the proposed Redmond Town Center (RTC) Apartments project in Redmond, WA. The study includes a summary of the traffic scoping analysis review and approved previously by the City of Redmond, a description the proposed project, a summary of existing transportation conditions at study intersections, trip generation estimate approved by the City of Redmond, project trip distribution and assignment, and future traffic operations with and without the proposed RTC Apartments project. Traffic Scoping Analysis In November 2015, the City of Redmond review and approved a Phase I scoping analysis prepared by TENW for the RTC Apartments project. This approval included a review of project trip generation, trip distribution, and identification of the following study intersections to be included in the Phase II traffic impact analysis: 1. 166th Avenue NE (private southern leg) at Cleveland Street ă A signalized intersection. 2. 166th Avenue NE (private southern leg) at NE 76th Street ă An all-way stop controlled intersection. 3. 168th Avenue NE (private) at NE 76th Street ă A two-way stop controlled intersection. 4. 170th Avenue NE (private southern leg) at NE 76th Street ă A signalized intersection. 5. 170th Avenue NE at Redmond Way ă A signalized intersection. Safety considerations and parking analysis review normally provided in the context of the Phase II traffic impact analysis has already been performed by the City of Redmond since the completion of the Phase I review, with sight distance, driveway configurations, and parking supply approvals documented. Project Description The proposed Redmond Town Center project is located on Parcel 5B within the existing Redmond Town Center development in Redmond, WA. A vicinity map showing the location of the site and the surrounding area is included in Figure 1. The proposed redevelopment would include a 6-story mixed use building containing approximately 286 residential units and 9,100 square-feet of ground-floor retail. Parking would be provided by a multistory parking garage with 522 garage parking stalls (to replace existing commercial parking and provide project parking) and 8 new on-street stalls. The project site is currently an existing surface parking lot within Redmond Town Center. Access to the projectÊs proposed parking garage would be provided via an internal private drive-aisle on the eastside of the existing MacyÊs between NE 76th Street and NE 74th Street (no new driveways are proposed). A ground-floor site plan is provided in Figure 2. ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 2 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 3 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 4 Existing Conditions at Study Intersections and Immediate Vicinity The proposed RTC Apartments project is located on Parcel 5B within the existing Redmond Town Center development in Redmond, WA. As the site is adjacent to the downtown Redmond core, arterial urban streets, transit service, and multiple freeway interchange access routes are available. Site vehicular access would be provided by mostly private streets within the Redmond Town Center development, but also directly from NE 76th Street, an east-west 5-lane public street immediately north of the subject property. East of 166th Avenue NE (most adjacent to the project), NE 76th Street carries approximately 3,850 average daily vehicles ADT (Source: City of Redmond Traffic Counts, 2014.) In comparison, Redmond Way, an east-west major arterial several blocks north of the site, currently carries approximately 34,150 ADT east of its intersection with 170th Avenue NE. Figure 3 highlights existing geometry and traffic control treatments at each of the study intersections, while Figure 4 overviews p.m. peak hour traffic counts collected by IDAX data solutions in 2016. Raw count data is provided in Attachment A. Project Trip Generation Weekday daily, AM and PM peak hour trip generation estimates for the proposed land uses were estimated based on trip rates published in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 9th Edition. Internal trips for the proposed residential uses within the overall Redmond Town Center were limited to the previous Redmond Town Center Traffic Impact Analysis, and as such, are considered conservative. The resulting estimated new weekday daily, AM, and PM peak hour trips are summarized in Table 1. A detailed trip generation estimate is in Attachment B. Table 1 Redmond Town Center Apartments Trip Generation Summary Net New Trips Generated Time Period In Out Total Weekday Daily 962 963 1,925 Weekday AM Peak Hour 30 64 94 Weekday PM Peak Hour 72 55 127 Source: Trip Generation Manual, 9th Edition, ITE, 2012. As shown in Table 1, the proposed Redmond Town Center Apartments development is estimated to generate 1,925 new weekday daily trips, with 94 new trips occurring during the weekday a.m. peak hour (30 entering, 64 exiting), and 127 new trips occurring during the weekday p.m. peak hour (72 entering, 55 exiting). Project Trip Distribution The distribution of the proposed apartment trips was estimated based on available access routes to/from the project site to regional freeway systems and directness or ease of circulation, and the overall distribution of local shopping/commercial areas and employment centers in the vicinity of the site. The resulting approved trip distribution of p.m. peak hour project trips is illustrated in Figure 5. Figure 6 illustrates the resultant trip assignment of project trips during p.m. peak hour at each study intersection. ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 5 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 6 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 7 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 8 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 9 Non-Project Forecasts Per the City of Redmond Traffic Impact Study Guidelines, a background growth rate of 2 percent per year were applied to existing 2016 traffic volumes documented as part of this traffic analysis. As the expected completion date of 2018 is anticipated by the applicant, a 2019 horizon year was assumed for building occupancy under which a 1.06 factor was applied to existing traffic counts. Figure 7 documents future 2019 traffic volumes at study intersections during the p.m. peak hour without and with the proposed RTC Apartment projects. Traffic Operational Impacts Level of service (LOS) 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 LOS. At signalized intersections, LOS A represents free-flow conditions-motorists experience little or no delays, and LOS F represents forced-flow conditions-motorists experience an average delay in excess of 80 seconds per vehicle. The LOS reported for signalized intersections represents the average control delay for all vehicles entering the intersection. The LOS reported at stop-controlled intersections is also based on the average control delay (sec/veh), but is reported for stop controlled and yield movements only. Table 2 outlines the LOS criteria for signalized and unsignalized intersections based on these methodologies. Table 2 Level of Service Criteria for Intersections Signalized Intersection Unsignalized Intersection Level of Service Average Delay Range (sec) Delay Range (sec) A  10  10 B > 10 to  20 > 10 to  15 C > 20 to  35 > 15 to  25 D > 35 to  55 > 25 to  35 E > 55 to  80 > 35 to  50 F > 80 > 50 Source: “Highway Capacity Manual”, Special Report 209, Transportation Research Board, 2010. A summary of existing (2016) intersection levels of service are provided at all study intersections in Table 3. As shown, all existing signalized and unsignalized study intersections currently operate at LOS D or better. Estimated project intersection LOS impacts during the p.m. peak hour in 2019 are summarized in Table 4. As shown, all signalized and unsignalized study intersections are estimated to operate at LOS D or better with or without the project in 2019, with no resultant significant adverse traffic operational impacts expected to occur as a result of the project. All study intersections would meet adopted LOS standards for the City of Redmond. Detailed LOS summary worksheets and queuing estimates at the signalized study intersections are included in Attachment C. As shown in Attachment C, all 95th-percentile critical vehicle queues are expected to remain within existing built storage areas. ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 10 ---PAGE BREAK--- Phase II Traffic Impact Analysis Redmond Town Center Apartments TENW June 21, 2016 Page 11 Table 3 2016 Intersection Levels of Service PM Peak Hour Study Intersection LOS Delay (sec) V/C Ratio Signal Controlled Intersections #1 166th Avenue NE/Cleveland Street B 17.4 0.55 #4 170th Avenue NE/NE 76th Street A 9.1 0.50 #5 170th Avenue NE/Redmond Way D 35.1 1.00 Stop Controlled Intersections #2 166th Avenue NE/NE 76th Street (all-way stop) A 9.9 0.39 #3 168th Avenue NE/NE 76th Street(NB stop approach) A 9.9 0.11 Source: TENW using Worst movement or approach group reported only for stop controlled intersections.

Conclusions The proposed Redmond Town Center Apartments development was evaluated for increased traffic demands and traffic operational impacts to key intersections within the project vicinity per City of Redmond standards. Approximately 1,925 daily, 94 new a.m. peak hour trips and 127 new p.m. peak hour vehicular trips are estimated to be generated by the project, but are not expected to result in any significant adverse traffic operational impacts or increase in average vehicle delay at any of the signalized or unsignalized study intersections per the detailed traffic operational impact analysis. To mitigate traffic impacts to system improvements planned by the City of Redmond, traffic impact fees are assessed for new development. As there remains entitlement capacity within the overall Redmond Town Center development area, the City is currently considering the applicantÊs and RTCÊs owners request to transfer trip credits in lieu of payment of traffic impact fees. If allowed, the applicant would pay RTC for the trip credits that get transferred. If the City does not allow the private transfer, the project would be assessed an estimated traffic impact fee of $1,047,004.92 by the City using a rate of $3,261.22 per apartment and $12.56 per square-foot of miscellaneous retail space.
