This is an update to our previous traffic analysis dated August 20, 2018 and reflects a revised site plan and addresses City of Redmond PREP 3 comments received October 17, 2018. Project Proposal. The proposed Modera River Trail project includes the development of 233 apartment units and 5,020 square feet (sf) of ground floor commercial space (preliminary assumption of 3,370 sf of retail and 1,650 sf of restaurant space). The existing site is currently occupied by a 10,362 sf office building and a 4,673 sf dental office building which would be demolished as part of the proposed project. Primary access to the site would be provided by a proposed full access driveway on 158th Avenue NE. The project is anticipated to be completed and occupied in 2021. Trip Generation. The proposed Modera River Trail development is estimated to generate 1,960 net new weekday daily trips with 52 net new trips occurring during the weekday AM peak hour (3 in, 49 out) and 100 net new trips occurring during the weekday PM peak hour (68 in, 32 out). It should be noted that the PM peak hour traffic operations analysis included is this study was based on an earlier site plan that included a more intense land use which resulted in a higher trip generation estimate (103 net new PM peak hour trips). Since the analysis documented in this report was based on a higher trip generation estimate, the results represent a conservative analysis. Transportation Concurrency. A concurrency application has been submitted to the City of Redmond. It is anticipated that transportation concurrency will be satisfied for the proposed project. Traffic Operations Analysis. A level of service (LOS) analysis was conducted at five off-site study intersections during the weekday PM peak hour. Based on the results, all study intersections are expected to operate at LOS C or better in the future with or without the project during the weekday PM peak hour. Site Access Analysis. Results of the LOS and queue analysis at the proposed site driveway on 158th Ave NE show that all controlled movements are estimated to operate at LOS B or better during the weekday PM peak hour with minimal queues. Parking. The applicant is proposing a parking ratio for the residential component of the project that is below the current City of Redmond Zoning Code requirements. A separate parking modification request memo dated October 22, 2018 was submitted to the City of Redmond requesting a parking modification to allow for a minimum residential parking ratio of 0.94 stalls per dwelling unit rather than the code-required 1.25 stalls per dwelling unit. The parking modification request was approved by the City of Redmond. Parking for the commercial uses is proposed to meet minimum code requirements. Mitigation Frontage/Access Improvements NE 85th Street: • Removal of three existing driveway curb-cuts. • Landscaping with street trees, new sidewalks, and street lighting. 158th Ave NE: • Removal of two existing driveway curb-cuts and replace with one new driveway near the southern property boundary. • New sidewalks and landscaping with street trees. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 2 Intersection of 158th Ave NE/NE 85th Street (southeast corner): • Addition of a pedestrian curb bulb extending onto NE 85th Street, provide new curb ramps, and accommodate a King County Metro bus stop. • Addition of a pedestrian curb bulb extending onto 158th Ave NE and rechannelize northbound approach to include a single lane. • Signal modifications including a new pedestrian pole(s) with push buttons and pedestrian heads. Off-Site Improvements Based on the results of the analysis shown in this report, no project-specific off-site transportation mitigation is proposed for concurrency or SEPA purposes. Transportation Impact Fees Long-term traffic impacts in the City of Redmond are mitigated by the projects included in the CityÊs Transportation Facilities Plan (TFP). The TFP projects are funded through the payment of City of Redmond transportation impact fees. Based on this process, a fee is assessed upon a development to pay for a proportionate share of the cost of public facilities needed to serve new growth and development. As of the date of this study, the adopted impact fee schedule for Downtown permits issued in 2018 identifies a fee of $3,885.35 per dwelling unit for Multifamily units, $14.96 per square foot for Miscellaneous Retail, $32.22 per square foot for restaurants, $18.40 per square foot for office, and $18.89 per square foot for medical/dental office. Based on these rates, a preliminary estimate of impact fees is $729,930.98 (including existing use credits). The applicant will pay the fees based on the size of the proposed land uses and impact fee rates in effect at the time of building permit issuance. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 3 INTRODUCTION This traffic impact analysis has been prepared for the proposed Modera River Trail mixed-use project located at 15801 & 15945 NE 85th Street within the Sammamish Trail (SMT) zone of downtown Redmond, WA (see Figure This is an update to our previous traffic analysis dated August 20, 2018 and reflects a revised site plan and addresses City of Redmond PREP Round 3 comments received October 17, 2018. Project Description The proposed Modera River Trail project includes the development of 233 apartment units and 5,020 square feet (sf) of ground floor commercial space (preliminary assumption of 3,370 sf of retail and 1,650 sf of restaurant space). The existing site is currently occupied by a 10,362 sf office building and a 4,673 sf dental office building which would be demolished as part of the proposed project. Primary access to the site would be provided by a proposed full access driveway on 158th Avenue NE. The project is anticipated to be completed and occupied in 2021. A preliminary site plan is provided in Figure 2. Project Approach The specific scope items used in the evaluation of traffic impacts were discussed and confirmed by City staff.

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 Traffic Volumes Existing weekday PM peak hour traffic volumes at the study intersections were based on counts conducted in September 2017 and August 2018. To estimate 2018 traffic volumes, a 2 percent annual growth rate was applied to the 2017 traffic counts. Figure 3 illustrates the existing 2018 PM peak hour traffic volumes at the study intersections. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 10 Figure 3 2018 Existing Weekday PM Peak Hour Traffic Volumes ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 11 Existing Level of Service Based on our scoping discussions and comments received from the City of Redmond, an existing weekday PM peak hour level of service (LOS) analysis was conducted at the following study intersections: 1. 154th Avenue NE / NE 90th Street (signalized intersection) 2. 154th Avenue NE / NE 85th Street (signalized intersection) 3. 158th Avenue NE / NE 85th Street (signalized intersection) 4. 160th Avenue NE / NE 85th Street (signalized intersection) 5. 160th Avenue NE / NE 83rd Street (all-way stop controlled intersection) Level of service calculations at the signals was based on 10.2 methodology. 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. Existing signal timing used in the analysis was provided by the City of Redmond. The 2018 existing weekday PM peak hour LOS analysis results at the study intersections are summarized in Table 4. The 2018 existing LOS worksheets are included in Appendix A.

The project maps from the TIP and unfunded Buildout Plan are shown below. There are no projects on the CityÊs Transportation Facilities Plan in the immediate study area. • NE 90th Street Bridge Deck Overlay (TIP Project P20): This project would reseal the concrete bridge deck with an epoxy overlay. • NE 90th Street Pavement Rehabilitation – Willows Rd to Red-Wood Rd (TIP Project P32): This project would rehabilitate and overlay the pavement surface to extend the useful life of the roadway. • NE 85th Street Bridge Deck Overlay (TIP Project P36): This project involves the rehabilitation of the concrete bridge deck on NE 85th Street over the Sammamish River. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 13 • 158th Ave NE Extension – NE 83rd St to Redmond Way (Unfunded Buildout Plan Project 170): This project includes the construction of a new 159th Ave NE from Redmond Way to NE 83rd Street. Improvements includes 1 through lane in each direction, parking, sidewalks, street lights, pedestrian amenities, transit stop amenities, storm drainage, right-of-way and easements. • Sammamish River Trail North (Lighting and Widening) – 520 Trail to NE 90th (Unfunded Buildout Plan Projects 184 and 296): Project 184 includes installation of lighting along this portion of the trail and considers other elements such as reflective delineators or fog lines. Project 296 includes widening the existing hard surface regional trail and improving existing section, as well as constructing missing links of parallel soft surface trail. • 160th Ave NE Shared Lane Markings – Cleveland St to NE 90th (Unfunded Buildout Plan Project 220): This project would add shared lane markings to roadway indicating proper positioning for cyclists along the bike route. • 154th Ave NE Sidewalk – NE 85th St to NE 90th St (Unfunded Buildout Plan Project 198): Construct 5 ft sidewalk on west side of 154th Ave NE. Include curb, gutter, and storm as applicable. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 14 Project Trip Generation The trip generation estimates for the proposed and existing uses were based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, and adjusted to account for the relatively high-density urban nature of Downtown Redmond. Downtown Redmond is designated as an Urban Center with a strong mix of residential, retail, and office employment, a compact transportation network, and relatively high rates of walking, bicycling, and transit use. Based on these factors, an adjustment to the standard ITE vehicular trip rates is warranted since the ITE manual is based on mostly low-density suburban sites with little or no transit service and minimal walking/bicycling. The City of Redmond has already adopted transportation policies that acknowledge the reduced traffic impact of development in the Urban Centers. The City applies a 10 percent reduction (0.90 factor) to the ITE-based vehicular trip generation factors for Downtown Redmond in its concurrency and impact fee programs. We believe the that this 10 percent reduction is reasonable to apply to the ITE vehicular trip generation estimates for this project and is consistent with existing City policies. Pass-by trips are trips that are made by vehicles that are already on the adjacent streets and make intermediate stops at the retail and restaurant uses on route to a primary destination (i.e. on the way from work to home). The pass-by trips were based on methodology and studies documented in the ITE Trip Generation Handbook, 3rd Edition. As a conservative measure and because ITE does not publish specific pass-by rates for daily and AM peak hour periods, no pass-by trip reductions were included in the weekday daily or AM peak hour trip estimates. Accounting for existing uses to be demolished, the resulting net new weekday daily, AM and PM peak hour trips are summarized in Table 5. A detailed trip generation estimate is included in Appendix B. Table 5 Modera River Trail Trip Generation Summary Net New Trips Generated Weekday Time Period In Out Total Weekday Daily 980 980 1,960 Weekday AM Peak Hour 3 49 52 Weekday PM Peak Hour 68 32 100 As shown in Table 5, the proposed Modera River Trail development is estimated to generate 1,960 net new weekday daily trips with 52 net new trips occurring during the weekday AM peak hour (3 in, 49 out) and 100 net new trips occurring during the weekday PM peak hour (68 in, 32 out). It should be noted that the PM peak hour traffic operations analysis included is this study was based on an earlier site plan that included a more intense land use which resulted in a higher trip generation estimate (103 net new PM peak hour trips). Since the analysis documented in this report was based on a higher trip generation estimate, the results represent a conservative analysis. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 15 Project Trip Distribution and Assignment The distribution of project trips was estimated based on previously approved projects and existing travel patterns in the study area. The new PM peak hour project-generated vehicle trips were generally distributed as follows: • 20 percent to/from the north on Willows Road NE • 20 percent to/from the south on 154th Avenue NE • 20 percent to/from the east on Redmond Way/Cleveland Street • 15 percent to/from the north on Redmond-Woodinville Road NE (SR 202) • 10 percent to/from the west on Redmond Way • 10 percent to/from the south on 166th Avenue NE • 5 percent to/from the north on 166th Avenue NE The trip distribution and assignment of net new PM peak hour trips to/from the project site is illustrated in Figure 4. As part of the proposed project, the three existing site driveways on NE 85th Street would be removed. As a result, some of the individual movements shown in Figure 4 may be negative due to the elimination of the existing site driveways. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 16 Figure 4 Weekday PM Peak Hour Project Trip Assignment ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 17 Transportation Concurrency A concurrency application was submitted to the City of Redmond in April, June, and August 2018. The concurrency application has since been updated (see Appendix The updated concurrency application shows the proposed project would generate a net new Mobility Unit (MU) demand of 261.15 net new MU. The mobility unit demand rates used for the proposed and existing uses were based on standard MU rates for downtown. Using this information, the City will determine whether enough MUs from the six-year program and the Transportation Facility Plan (TFP) can be supplied to meet travel demand from the development at the time of opening, or within six years. If the MU supply is available to serve the MU demand from the development, the City will issue a certificate of concurrency. It is expected that the current MU supply will accommodate the additional MU demand created by the proposed Modera Redmond project. Therefore, it is anticipated that a certificate of concurrency will be issued for the project. Future Traffic Operations Future Traffic Volumes To estimate the future 2021 Without Project PM peak hour traffic volumes, a 2 percent annual growth rate was applied to the 2018 existing traffic volumes. In addition to the 2 percent annual background growth rate, trips from the following 3 pipeline projects (as directed by the City) were included in the future without-project traffic volumes: Modera I (6706 161st Ave NE) Redmond Townhomes (northeast corner of 166th Ave NE/NE 85th Street) Redmond City Center (16135 NE 85th Street) Figure 5 illustrates the future 2021 Without Project PM peak hour traffic volumes without the proposed Modera River Trail project at the study intersections. To determine the future year with-project traffic volumes, the net new project-generated trips which are shown in Figure 4 were added to the future baseline volumes to obtain future with-project traffic volumes. The resulting total with-project PM peak hour traffic volumes at the study intersections and site access driveway are shown in Figure 6. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 18 Figure 5 2021 Without Project Weekday PM Peak Hour Traffic Volumes ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 19 Figure 6 2021 With Project Weekday PM Peak Hour Traffic Volumes ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 20 Future Level of Service A future Level of Service (LOS) analysis was conducted at the five study intersections for weekday PM peak hour future 2021 Without Project conditions and for future 2021 With Project conditions. Existing signal timing and channelization at the study intersections were used in the future LOS analysis with exception to the intersection of 158th Ave NE/NE 85th Street. The future with-project scenario at 158th Ave NE/NE 85th Street includes the proposed re-channelization of the south leg to include a pedestrian curb bulb and a single-lane northbound approach. The future weekday PM peak hour LOS results at the study intersections without and with the proposed Modera River Trail project are summarized in Table 6. The LOS worksheets are included in Appendix A. As shown in Table 6, all study intersections are expected to operate at LOS C or better in the future with or without the project during the weekday PM peak hour. Site Access Analysis To evaluate the operations of the proposed site access driveway, a level of service (LOS) and queue analysis was completed. Vehicular access to/from the site would be provided by a new full access driveway on the east side of 158th Ave NE at the south end of the site. It should be noted that three existing driveways on NE 85th Street and two existing driveways on 158th Ave NE would be removed as part of the proposed project. The weekday PM peak hour LOS and queue analysis at the site access driveway were based on the methodology outlined in the 6th Edition of the Highway Capacity Manual using 10.2 software. The estimated future weekday PM peak hour traffic volumes with the proposed project at the site driveways are shown in Figure 6. Table 7 summarizes the calculated LOS and the 95th percentile queues of the controlled movements at the proposed site access driveway during the weekday PM peak hour. The reported 95th percentile queues represent a condition that is exceeded only 5 percent of the time. Detailed LOS and queue calculation worksheets are included in Appendix A.

Parking The applicant is proposing a parking ratio for the residential component of the project that is below the current City of Redmond Zoning Code requirements. A separate parking modification request memo dated October 22, 2018 was submitted to the City of Redmond requesting a parking modification to allow for a minimum residential parking ratio of 0.94 stalls per dwelling unit rather than the code-required 1.25 stalls per dwelling unit. The parking modification request was approved by the City of Redmond. Parking for the commercial uses is proposed to meet minimum code requirements. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail TENW November 8, 2018 Page 22 MITIGATION Frontage/Access Improvements NE 85th Street: • Removal of three existing driveway curb-cuts. • Landscaping with street trees, new sidewalks, and street lighting. 158th Ave NE: • Removal of two existing driveway curb-cuts and replace with one new driveway near the southern property boundary. • New sidewalks and landscaping with street trees. Intersection of 158th Ave NE/NE 85th Street (southeast corner): • Addition of a pedestrian curb bulb extending onto NE 85th Street, provide new curb ramps, and accommodate a King County Metro bus stop. • Addition of a pedestrian curb bulb extending onto 158th Ave NE and rechannelize northbound approach to include a single lane. • Signal modifications including a new pedestrian pole(s) with push buttons and pedestrian heads. Off-Site Improvements Based on the results of the analysis shown in this report, no project-specific off-site transportation mitigation is proposed for concurrency or SEPA purposes. Transportation Impact Fees Long-term traffic impacts in the City of Redmond are mitigated by the projects included in the CityÊs Transportation Facilities Plan (TFP). The TFP projects are funded through the payment of City of Redmond transportation impact fees. Based on this process, a fee is assessed upon a development to pay for a proportionate share of the cost of public facilities needed to serve new growth and development. As of the date of this study, the adopted impact fee schedule for Downtown permits issued in 2018 identifies a fee of $3,885.35 per dwelling unit for Multifamily units, $14.96 per square foot for Miscellaneous Retail, $32.22 per square foot for restaurants, $18.40 per square foot for office, and $18.89 per square foot for medical/dental office. Based on these rates, a preliminary estimate of impact fees is $729,930.98 (including existing use credits). The applicant will pay the fees based on the size of the proposed land uses and impact fee rates in effect at the time of building permit issuance. ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail Appendix A Level of Service (LOS) Calculations at Study Intersections ---PAGE BREAK--- Updated Transportation Impact Study Modera River Trail 2018 Existing ---PAGE BREAK--- Lanes, Volumes, Timings 1: 154 Ave NE & NE 90 St 08/20/2018 Modera River Trail 10 Report 2018 Existing - PM Peak Hour Lane Group EBT EBR WBL WBT NBL NBR Lane Configurations Traffic Volume (vph) 664 242 149 322 302 311 Future Volume (vph) 664 242 149 322 302 311 Satd.
