The EIS was previously issued on October 9,1995 (File #L92-0053). The addendum addresses the review and update of the Comprehensive Plan that is required by the Washington Growth Management Act per RCW36.70a.130. It updates the horizon year of the Plan from 2030 to 2031 and includes the PSRC's household and employment forecast for that year. The change includes a updated narrative and maps to reflect the 2031 forcast year and a distribution of the expected reduced numbers for that year. This is a non -project (programmatic) EIS addendum. Copies of the addendum, and original FEIS are available for review at: City of Tukwila Department of Community Development 6300 Southcenter Boulevard, Tukwila, WA 98188 Office hours: 8:30 a.m. to 5 p.m. The addendum is also available online at: http://www.tukwilawa.gov/dcd/dcdcompplan.html Staff contact: Moira Bradshaw, Senior Planner Moira.bradshaw@tukwilawa.gov 206-431-3670 Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov STAFF EVALUATION FOR SEPA ADDENDUM File No: E17-0009 I. SUMMARY OF PROPOSED ACTION The proposal is an addendum to the FEIS for the 1995 Comprehensive Land Use Plan and is a revision of the background analysis for the required periodic 2015 Growth Management Act (GMA) Update to the Comprehensive Plan. This is a non -project action. II. GENERAL INFORMATION Project Name: Update of analysis for Tukwila's Comprehensive Plan using PSRC's 2031 Household and Employment forecasts and modeling transportation effects per the 2031 numbers Applicant: City of Tukwila Location: Citywide Zoning and Comprehensive Plan Designation: Citywide The following information was considered as part of review of this application. The Draft Memo from Fehr and Peers summarizing updated the analysis and includes revisions to two Transportation Element maps, which show the 2031 distribution of the lower household and employment forecast numbers. 11I. REVIEW PROCESS The proposed action is subject to State Environmental Policy Act (SEPA) review as the project does not meet the exemptions listed under WAC 197-11-800. IV. PROPOSAL No changes to the goals, policies, or projects resulted from the analysis. Background narrative was updated with a memo and the maps showing household and employment growth were amended to reflect the 2031 growth. The City Council can adopt comprehensive Plan amendments once per year, except in cases of emergency, as authorized by the Growth Management Act (RCW 36.70A) and the Tukwila Municipal Code Chapter 18.80. The amendments discussed in this Addendum will be adopted E17-0009 2016-2017 Comprehensive Plan Amendment Docket Page 1 of 2 by December 31, 2017. This is a non -project (programmatic) EIS Addendum. V. SEPA COMPLIANCE: The Draft EIS (DEIS) for the Comprehensive Land Use Plan was issued on June 27,1995 (File # L92- 0053). It was circulated to adjacent jurisdictions, affected agencies and other parties with an interest. Comments were due on August 11,1995 (extended from July 27, 1995). After comments were reviewed, the Final EIS (FEIS) was issued on October 9,1995. An addendum to the FEIS addressing Zoning Code amendments was issued on November 15,1995. Both the Comprehensive Land Use Plan and Zoning Code were adopted on December 4,1995. In 2015, an addendum to the FEIS was prepared. The addendum addressed: 1) Transportation and 2) Shoreline elements to reflect changes to the Growth Management Act. The addendum to the FEIS was issued on March 26, 2013. VI. ENVIRONMIENTAL ELEMENTS: This is a non -project action. All environmental elements were adequately addressed by the 1995 Draft and Final Environmental Impact Statement for the City of Tukwila Comprehensive Plan, and the 2013 Addendum. Further, subsequent "project" actions will require the submittal of separate environmental review. These will be analyzed for consistency with the original mitigating conditions and could require new mitigation based on conditions. VII. SUMMARY OF AMENDMENTS: The year of analysis for the City's required periodic update changed from 2030to2031 and the result was a reduction in forecast households - from 4,860 to 4,800 and in employment - from 27,670 to 15,500. An analysis of the implications to Tukwila's goals, policies and capital projects was done and no change is anticipated. VII. CONCLUSION/RECOMMENDATION The City of Tukwila Draft and Final EIS provided extensive analysis of the environmental impacts associated with implementing the 1995 Comprehensive Plan. The proposed changes are such that none results in significant impacts, some reduce potential environmental impacts and all remain within the range of alternatives examined in the DEIS and FEIS. Staff has reviewed the updated information and has found that they are consistent with the scope of the EIS. Therefore, this action will not create additional or significant impacts and does not warrant separate environmental review as outlined in the State Environmental Policy Act (SEPA), WAC 197-11.

The employment and household forecasts were lowered from what was originally assumed for the 2015 periodic update of the City's Comprehensive Plan. Comprehensive Plan amendments can be adopted by the City Councilonce per year, except in cases of emergency, as authorized by the Growth Management Act (RCW 36.70A) and the Tukwila Municipal Code Chapter 18.80. The amendments discussed in this Addendum will be adopted prior to December 31, 2017. This is a non -project (programmatic) EIS Addendum.

It was circulated to adjacent jurisdictions, affected agencies and other parties with an interest. Comments were due on August 11, 1995 (extended from July 27, 1995). After comments were reviewed, the Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov E17-0004 July 31, 2017 Page 2 Final EIS (FEIS) was issued on October 9,1995. An addendum to the FEIS addressing Zoning Code amendments was issued on November 15,1995. Both the Comprehensive Land Use Plan and Zoning Code were adopted on December 4,1995. In 2013 (File E13-004), an addendum to the FEIS was prepared. The addendum addressed revised and new goals and policies associated with the City's required periodic update. Environmental Review —Scope of EIS Addendum (File #E17-0009): The EIS analyzed environmental impacts of the Comprehensive Plan in order to assess the impacts of the Plan on Tukwila and its growth area. The EIS did not analyze the significance of site -specific impacts; rather it focused on area -wide impacts for this non-project/programmatic document. The City of Tukwila used a phased environmental review in preparing an Addendum to the EIS as it did its periodic update of its Comprehensive Plan to address changes to the Growth Management Act, and regional growth policies. The State Environmental Policy Act (SEPA) and rules established for the act, WAC 197-11, outline procedures for the use of existing environmental documents and preparing addenda to environmental decisions. Environmental Elements: All environmental elements were adequately addressed by the 1995 Draft and Final Environmental Impact Statement for the City of Tukwila Comprehensive Plan (File #L92-0053), and the 2013 Addendum. Further, subsequent "project" actions will require the submittal of separate environmental review. These will be analyzed for consistency with the original mitigating conditions and could require new mitigation based on specific conditions. Changes to Comprehensive Plan policies addressed in the 2015 periodic update reflect regional policies contained in documents (Vision 2040 and King County Countywide Policy Plan) that have received environmental review, and whose intent is to minimize environmental impacts through sustainable development , and compact regional growth patterns. Summary of Amendments The proposed amendments discussed in this addendum address the Puget Sound Regional Council's (PSRC) request for a review and update of Comprehensive Plan impacts associated with the 2031 household and employment forecasts. (The City used 2030 forecasts when it reviewed and updated its Transportation Element. The narrative in the Transportation Element has been updated to reflect the 2031 forecasts. The review of the modeling with 2031's lower forecasts indicates there needs to be no change in goals, policies or projects. Recommendation: The City of Tukwila Draft and Final EIS provided extensive analysis of the environmental impacts associated with implementing the 1995 Comprehensive Plan. The nature of the proposed changes is such that none results in significant impacts, some reduce potential environmental impacts and remain within the range of alternatives examined in the DEIS and FEIS.

PSR.C's review noted that the employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. The discrepancy in the land use growth allocation occurred because the City of Tukwila updated the Transportation Element between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008-2009 recession and resulting slowdown in the real estate market. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. In response to this comment, the City hired Fehr & Peers to reallocate land use growth to be consistent with current PSRC Land Use Vision and to re -run the City's travel demand model. Key findings include: • The 2031 forecasted traffic volumes are not expected to grow as much within the City compared to the previous analysis (VMT is lower by three percent). • Most of the forecasted traffic volume decreases are in the Tukwila South area, where growth is not as rapid as was previously anticipated and where most of the employment growth was reduced. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com L. Benjamin July 28, 2017 Page 2 of 2 fr • No changes are recommended to the proposed transportation capital improvement projects. Most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks. The large roadway projects to facilitate growth in Tukwila South were completed by the developer in the 2010-2012 timeframe. Attached is a memo detailing the analysis to reallocate land use growth to be consistent with current forecasts, as well as two maps that illustrate the distribution of household and employment growth by 2031 within the City.

Sincerely, FEHR & PEERS Carmen Kwan Transportation Engineer/Planner 5E76-0498 Attachment: • Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments Memo • FEHRk PEERS MEMORANDUM Date: December 30, 2016 To: Robin Tischmak and Bob Giberson, City of Tukwila From: Carmen Kwan and Chris Breiland, Fehr & Peers Subject: Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments 5E16-0498 The Puget Sound Regional Council (PSRC) reviewed the City of Tukwila's draft Comprehensive Plan Elements in 2013 and identified that the land use growth forecast by 2031 in the Transportation Element was higher than current PSRC growth assumptions. In response to this comment, the forecast land use growth was revised to be consistent with PSRC assumptions and the City's travel demand model was re -run. This document details the analysis process and summarizes the new model results. The transportation capital improvement projects previously proposed were also reviewed to identify if any changes in the project list would be necessary based on the new growth forecasts. BACKGROUND The City of Tukwila updated the Transportation Element of the Comprehensive Plan between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008- 2009 recession and resulting slowdown in the real estate market nationwide. In general, the earlier PSRC land use forecasts predicted more growth by 2031 than the current (2016) land use forecasts. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. The rest of this memorandum describes the method used to align the Transportation Element growth forecasts with the rest of the Comprehensive Plan. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com City of Tukwila December 30, 2016 Page 2 of 5 ANALYSIS METHODOLOGY The previous analysis completed for the Transportation Element assumed a growth of 27,665 jobs and 4,905 households by 2031. PSRC's review noted that this employment growth for the City of Tukwila is almost double the current forecast of 15,500job growth between 2010 and 2031. PSRC also forecasts a slightly lower number of households in the city by 2031 (4,800 new households). Land Use Revision In response to these comments, the 2031 land use assumptions were revised and the City's travel demand model was re -run to evaluate how traffic forecasts would change from the previous 2031 analysis (prepared with the higher growth forecasts). Key assumptions are listed below: • Land use forecasts were revised to match the Land Use Vision (LUV.1) Dataset, the most recent land use forecasts released by the PSRC in September 2015. • Land use growth assumptions in the Southcenter Subarea of Tukwila remained relatively consistent with the Southcenter Regional Growth Center EIS analysis prepared in 2014. Growth was adjusted elsewhere in the City based on the LUV.1 Dataset. A summary of the assumed land use growth is presented in Table 1. The revised 2031 forecasts show that the land use assumptions are consistent with PSRC growth assumptions of 4,800 households and 15,500jobs between 2010 and 2031. The revised 2031 land use has a decrease of 105 households and 14,140jobs compared to the previous analysis. Land use growth assumptions by TAZ are in Attachment A. TABLE 1.

City of Tukwila December 30, 2016 Page 3 of 5 MODELING RESULTS The City's travel demand model was re -run with the revised land use growth assumptions described earlier. An example travel demand model difference plot of the change in PM peak hour traffic volume per travel lane is shown in Figure 1. The green bars show a decrease in vehicle traffic and the red bars show an increase in vehicle traffic compared to the previous 2031 analysis. FIGURE 1. 2031TRAVEL DEMAND MODEL DIFFERENCE PLOT Source: Fehr & Peers, 2016. City of Tukwila December 30, 2016 Page 4 of 5 While there is some model "noise" in the difference plot results where some routes have minor increase or decrease in vehicle volumes compared to before, the overall observations from the new travel model runs are summarized below. • The 2031 forecasted traffic volumes are not expected to grow as much within the City of Tukwila compared to the previous analysis. The slightly lower vehicle traffic growth is reasonable based on the reduction of approximately 14,100 jobs and 100 households throughout the City by 2031 compared to the previous analysis. The new 2031 model run's slightly lower traffic growth is minor as there is only a three percent decrease in vehicle - miles -travelled (VMT) on City streets during the PM period compared to the previous analysis (excluding freeways). • Most of the forecasted traffic volume decreases are south of S 180th Street. This is expected as the growth near Southcenter Regional Growth Center did not change much from the earlier analysis, and most of the employment reduction was in the Tukwila South area, where growth is not as rapid as was anticipated in the earlier forecasts. Overall, City staff felt this area had the least amount of momentum for growth compared to the rest of the City. • No changes are recommended to the proposed transportation capital improvement projects. A review of the previously recommended projects was completed based on the new model run results. In general, all the projects identified in the Transportation Element are recommended to remain because: o Most of the street extension projects were recommended to reduce block size and improve mobility for all modes. These projects would improve street grid connectivity, improve the walkability by breaking up large blocks, and potentially improve emergency response times. While there is a minor decrease in vehicle volumes in the new model run compared to the previous results, projects are recommended to remain to help the City achieve the desired urban form and street network connectivity pattern. o Intersection improvements at various intersections such as adding turn pockets are still recommended as the model shows that turning volumes that triggered the additional turn lanes will not decrease enough to eliminate the need for the additional lanes. o Many projects were identified to enhance pedestrian and/or bicycle facilities. While growth its slightly lower with the new land use forecasts, the need for a City of Tukwila December 30, 2016 Page 5 of 5 comprehensive and connective pedestrian and bicycle network is not altered by the revised land use forecasts. CONCLUSION A new travel model run was completed with revised 2031 land use growth reallocated to be consistent with PSRC's vision of 15,500 new jobs and 4,800 new households between 2010 and 2031 in Tukwila. Based on the results of the new travel model run, no changes to the Transportation Element project list are recommended. While the traffic growth by 2031 is not expected to be as high as the previous analysis (VMT is lower by three percent), most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks.

BACKGROUND In 2010 the Public Works Department initiated an effort to update the Transportation Element (Chapter 13) of the Tukwila Comprehensive Plan. The effort included a traffic modeling effort that included projected household and employment growth throughout the City through the year 2030 This effort was in conjunction with an overall update to the Comprehensive Plan. Subsequently, the Puget Sound Regional Council (PSRC) provided updated growth data that reflected the 2008-2009 recession. The updated growth data showed a small reduction for projected household growth and a significant reduction in projected employment (nearly 50%). DISCUSSION The review by PSRC identified discrepancies within Tukwila's Plan that indicated conflicting growth information between different chapters of the plan as well as a differing projected end year, The modeling effort projected through year 2030 while the remainder of the plan projected through year 2031. PSRC requested that the City run a revised model update that reflected the updated growth data as well as the 2031 horizon year. Attached are the proposed revisions for consideration and approval. FINANCIAL IMPACT There is no financial impact. RECOMMENDATION Council is being asked to accept the attached Transportation Element revisions and forward this item for discussion at the August 28, 2017 Committee of the Whole Meeting and subsequent September 5, 2017 Regular Council Meeting.

PSRCs review noted that the employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. The discrepancy in the land use growth allocation occurred because the City of Tukwila updated the Transportation Element between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008-2009 recession and resulting slowdown in the real estate market. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. In response to this comment, the City hired Fehr & Peers to reallocate land use growth to be consistent with current PSRC Land Use Vision and to re -run the Citys travel demand model. Key findings include: • The 20311oiecaste :traffic v010 smaIttoppekpeetecl S owras>rnulti viithir th Cit' compared'to the previousariaiys (VMT is Tower by three percent). • lrdi st of the;forecasted .trafficvolume.decreases Wei the_ ukwwiia death ea, where growth is not as rapid as was previously anticipated and where most of the employment growth was reduced. 1001 AvenJe I Suite 4120 I Seatte, WA 981541(206) 56-422C I Fax (206) 576-4225 WWW.rehrartepeers.corn 5 L.

Most of the proposed transportationimprovement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks. The large roadway projects to facilitate growth In Tukwila South were completed by the developer in the 2010-2012 timeframe. Attached is a memo detailing the analysis to reallocate land use growth to be consistent with current forecasts, as well as two maps that illustrate the distribution of household and employment growth by 2031 within the City.

The EIS was previously issued on October 9,1995 (File #L92-0053). STAFF: Robin Tischmak, City Engineer ATTACHMENTS: A. Fehr & Peers Memo B. Transportation Element Revisions Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov 7 FINDINGS BACKGROUND In 2010 the Public Works Department began updating the Transportation element of Tukwila's Comprehensive Plan as part of a phased review and update mandated by the State. The update included a traffic modeling effort based on projected household and employment growth throughout the City until the year 2030. These growth numbers were determined at a regional level and provided to each jurisdiction for use in long range planning efforts. After Tukwila's updated element was adopted the Puget Sound Regional Council (PSRC) developed revised growth projections that reflected the reduced economic activity due to the 2008-2009 recession. These numb ers showed a small reduction in projected household growth and a aguifiic,ft t .eductiofl i projecie "erriployihei t growth (nearly'50% The other elements of the Tukwila Comprehensive Plan were updated in later phases using the revised PSRC numbers and a 2031 time horizon, leading to an internal discrepancy in the Plan. Tukwila received conditional approval for its Plan update in 2016 with the requirement that the discrepancy be addressed through adoption of an updated Transportation Element by December of 2017. Attachment B contains the proposed revisions to meet the PSRC requirements for certification. The Transportation and Infrastructure Committee was briefed on August 14, 2017 and they forwarded the issue to the Planning Commission for review. COMPREHENSIVE PLAN REVIEW CRITERIA Planning Commission review is required for Comprehensive Plan and Zoning Code amendments. The Planning Commission may recommend approval, recommend approval with conditions or recommend denial of the amendment based on a clear compliance with the criteria that follow. The Planning Commission's recommendation will be forwarded to the City Council, which will make the final decision. (TMC 18.80 and 18.84) 1) Describe how the issue is addressed in the Comprehensive Plan. If the issue is not adequately addressed, is there a need for it? The proposed update is a technical correction to the growth projections used in the Transportation Element needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The lower employment projections resulted in estimates of lower vehicle miles traveled and no lowering of levels of service (LOS). As a result of this change no goals, policies or capital improvement project changes are proposed as part of this action. The changes involve text edits to the narrative and updated maps. 2) If the issue is not adequately addressed in the Comprehensive Plan, is there a need for the proposed change? Under the original, higher projections we received from PSRC Tukwila had planned to accommodate higher household and employment growth than currently projected. Much of this growth was anticipated in the Tukwila South area, which remains largely undeveloped. The timeline for development is unclear, though at least some is likely to occur within the 2031 time horizon of the current Comprehensive Plan. Page 2 of 3 8 3) Is the proposed change the best means for meeting the identified public need? What other options are there for meeting the identified public need? As part of the conditional certification process the City of Tukwila agreed to the following conditions: 1. Tukwila City Council adoption of a plan of work that addresses the condition identified in the certification report by May 31, 2016. Adopted 5/2/2016 2. Submission of a draft amended comprehensive plan and supporting documents that address the condition to PSRC for review and comment in advance of adoption. Sent August 14, 2017, PSRC has confirmed that these changes are adequate to meet the condition. 3. Once the condition is adequately addressed, submission of adopted amended comprehensive plan and supporting documents by December 31, 2017 for review and certification by PSRC. 4) Will the proposed change result in a net benefit to the community? Gaining full certification for Tukwila's Comprehensive Plan will maintain our eligibility for PSRC and Regional Transportation Improvement Program funding. CONCLUSIONS In reviewing Comprehensive Plan criteria, staff concludes that the proposed update is a technical correction to the growth projections used in the Transportation Element needed to bring intennal consisiency to the Comprehensive Plan and meet PSRC conditions for certification. The projected traffic levels are lower under the revised employment levels and therefore no impacts are expected that were not already addressed under the original Element. As a result of this change no goals, policies or capital improvement project changes are needed or proposed as part of this action. RECOMMENDATION Staff recommends that the Planning Commission forward the proposed edits and updates to the Transportation Element shown in Attachment B to the City Council with a recommendation of adoption.

The update included a traffic modeling effort based on projected household and employment growth throughout the City until the year 2030. These growth numbers were determined at a regional level and provided to each jurisdiction for use in long range planning efforts. After Tukwila's updated element was adopted, the Puget Sound Regional Council (PSRC) developed revised growth projections that reflected the reduced economic activity due to the 2008-2009 recession. These numbers showed a small reduction in projected household growth and a significant reduction in projected employment growth (nearly 50%). The other elements of the Tukwila Comprehensive Plan were updated in later phases using the revised PSRC numbers and a 2031 time horizon, leading to an internal discrepancy in the Plan. Tukwila received conditional approval for its Plan update in 2016 with the requirement that the discrepancy be addressed through adoption of an updated Transportation Element by December of 2017. COMPREHENSIVE PLAN REVIEW CRITERIA 1) Describe how the issue is addressed in the Comprehensive Plan. If the issue is not adequately addressed, is there a need for it? The Transportation Element update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The lower employment projections resulted in estimates of lower vehicle miles traveled and no lowering of levels of service (LOS). Asa result of this change, no goals, policies, or capital improvement project changes are proposed as part of this action. The changes involve text edits to the narrative and updated maps. 2) If the issue is not adequately addressed in the Comprehensive Plan, is there a need for the proposed change? Under the original Background Report and 2010 model run, higher projections were received from PSRC. Tukwila had planned to accommodate higher household and employment growth than currently projected. Much of this growth was anticipated in the Tukwila South area, which remains largely undeveloped. The timeline for development there is unclear, though at least some is likely to occur within the 2031 time horizon of the current Comprehensive Plan. The new traffic model run using the 2031 forecasts provides internal consistency throughout the Comprehensive Plan and is being documented in the revised language and maps. Page 1 of 5 19 Exhibit A 3) Is the proposed change the best means for meeting the identified public need? What other options are there for meeting the identified public need? As part of the conditional certification process the City of Tukwila agreed to the following PSRC conditions: 1. Tukwila City Council adoption of a plan of work that addresses the condition identified in the certification report by May 31, 2016. Adopted 5/2/2016 2. Submission of a draft amended comprehensive plan and supporting documents that address the condition to PSRC for review and comment in advance of adoption. Sent August 14, 2017, PSRC has confirmed that these changes are adequate to meet the condition. 3. Once the condition is adequately addressed, submission of adopted amended comprehensive plan and supporting documents by December 31, 2017 for review and certification by PSRC. 4) Will the proposed change result in a net benefit to the community? Gaining full certification for Tukwila's Comprehensive Plan will maintain the City's eligibility for PSRC and Regional Transportation Improvement Program funding. In reviewing Comprehensive Plan criteria, staff concludes that the proposed update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The projected traffic levels are lower under the revised employment levels and therefore no impacts are expected that were not already addressed under the original Element. As a result of this change, no goals, policies or capital improvement project changes are needed or proposed as part of this action. Flower Power Comprehensive Plan and Zoning Map Change Background This application is part of the 2016-2017 annual docket for amendment of the Comprehensive Plan. The purpose of an annual docket is to ensure that changes to the Comprehensive Plan are only considered once a year and that they are considered concurrently and so the cumulative impact of the proposals can be determined. The applicant is seeking changes in the Comprehensive Plan and Zoning maps for a 28,270-square foot lot located at 13407 48th Ave. S., Tukwila, Washington, King County tax parcel no. 261320-0028 (the "Site") from Low Density Residential (LDR) to Commercial Light Industrial (C/LI) for the following reasons: 1. As the resident of the home located on the Site, he thinks that the noise from the LINK trains is unacceptable for a residential setting; 2. As the property owner of the Site since 1992, he has had much flooding from the Southgate stream that travels along the south and east sides of the Site and along the edge of the existing Page 2 of 5 20 Exhibit A home. A 2003 City project to install a high flow by-pass upstream of the site does not alleviate all flooding, which continues during rain storms. 3. He owns and operates a business growing bean sprouts, which he sells commercially and that is being displaced by a King County levee project in Kent. He would like to relocate his operation to this Site where he currently lives. C/LI zoning on the Site would allow the hydroponic growing of the bean sprouts and their assembly and distribution. This non -project proposal is a quasi-judicial change to the land use designation on the Tukwila Comprehensive Plan and Zoning maps. If the zoning is changed, any C/LI use would be permitted subject to all City regulations; however, the applicant has stated his intent to construct a new commercial/light industrial building for his hydroponic bean sprout business. The applicant submitted; an existing site plan and a proposed site plan as an example of his intent. COMPREHENSIVE PLAN AND ZONING MAP CHANGE CRITERIA 1) The proposed amendment to the [Comprehensive Plan and] zoning map is consistent with the goals, objectives, and policies of the Comprehensive Plan. Comprehensive Plan policies discuss having identifiable boundaries for residential districts. Access and orientation of Tots has an impact on the quality of the residential environment. Most single-family home owners prefer to see the same use across the street from them as evidenced by City policy of "identifiable neighborhood boundaries." The Site's existing orientation is to S. 134th Place, which is a commercial local access street, rather than to 48th Avenue S., which is a residential local access street. The existing structure, a home, sits at an elevation that is significantly below 48th Avenue S. which would make access via 48th Avenue more difficult, expensive, and potentially more 6mpactful to Southgate stream than access via 134th Place. Thus, because access via S. 134th Place is preferred, including this Site in the C/LI district would be a logical boundary. In addition, the Comprehensive Plan's natural environment policies would support the redevelopment of the Site and the restoration of the buffer for the Southgate stream. A C/LI designation would potentially encourage the redevelopment of the Site. The Flower Power application for a map change is supported by the following Comprehensive Plan policies: The Residential Neighborhoods Element goal: A land use pattern that encourages a strong sense of community by grouping compatible and mutually supportive uses and separating incompatible uses. (Goal 7.1) The policies of that Element then speak about recognizable boundaries: Maintain a comprehensive land use map that supports the preservation and enhancement of single family and stable multi family neighborhoods; eliminates incompatible land uses; and clearly establishes applicable development requirements through recognizable boundaries. (Policy 7.1.1) Page 3 of 5 21 Exhibit A The C/LI zoned lot along the Site's north edge, 4625 S. 134th Place, is improved with an older house, but the lot is being used for parking for Holaday Park, which is the business located across S. 134th Place street (and in a C/LI district,) blurring the boundaries for these distinct zoning districts. The Natural Environment Element has the following goal: Watercourses and their buffers, .... are protected from encroachment and degradation and improved through mitigation, enhancement, and restoration projects. (Goal 4.6) It is difficult to see the development on the Site because the vegetation covers the site and stream; however, the existing structure was constructed over 7 decades ago in the stream buffer prior to enactment of the City's environmental regulations. A relevant Economic Development Element policy is: Promote and preserve economic use of industrial lands outside the MIC through appropriate buffering requirements and use restrictions. (Economic Development Policy 2.1.16) The applicant also lists an Economic Development Policy related to promoting and supporting business formation, expansion and the importance of the City's entrepreneurs and small businesses in creating jobs. The applicant references several policies in the Community Image and Identity Element related to local food production and urban agriculture. 2) The proposed amendment to the Zoning Map is consistent with the scope and purpose of this title (the Zoning Code) and the description and purpose of the zone classification applied for. The purpose of the Commercial/Light Industrial (C/LI) designation and zone are, "...to provide for areas characterized by a mix of commercial, office, or light industrial uses. The standards are intended to promote viable and attractive commercial and industrial areas." (TMC 18.30.010) The Site is similar in character to the adjacent C/LI properties to the north in that it has frontage along S. 134th Place, has Southgate stream along its street frontage, has frequent truck traffic along it's frontage, and is similar in topography. The applicant discusses developing a commercial/light industrial business that would be consistent with the proposed Zone and the Site contains the characteristics of similar C/LI properties. The proposed C/LI zoning would allow the applicant to relocate his existing business, which is a hydroponic bean sprout grow operation, to the City of Tukwila from the City of Kent. His business is currently housed in a warehouse in Kent that is being displaced due to a Green River Levee project. The C/LI zone allows commercial greenhouses with no size limit whereas in LDR, greenhouses are allowed up to 1,000 square feet.) In contrast, the purpose of the Low Density Residential (LDR) district is "... to provide low -density family residential areas together with a full range of urban infrastructure services in order to maintain stable residential neighborhoods, and to prevent intrusions by incompatible land uses." (TMC 18.10.010) Except for the Site, the zoning designation of all properties fronting along S. 134th Place are C/LI. Page 4 of 5 22 Exhibit A The Site is rectangular with the narrow portion of the lot is along 48th Avenue S and the long side of the lot is along 134th Place. The Zoning Code stipulates that lot frontage shall be "considered the narrowest part of the lot that abuts a street." Because the Site is a corner lot and because there is a significant grade difference between 48th Avenue S. and the Site, access to the Site and overall orientation of the property is currently from S. 134th Place. 3) There are changed conditions since the previous zoning became effective 10 warrant the proposed amendment to the Zoning [and Comprehensive Plan] Map. In 2007, a Type 2 Special Permission for a buffer reduction was granted to the property owner of 4501 S. 134th Place. Sound Transit acquired and in 2009 consolidated 11 residentially zoned parcels across 48th Avenue S and diagonally across the street from the Site. There was a Comprehensive Plan and Zoning map change in 2010 when 4300 S. 133rd S. was rezoned from C/LI to Medium Density Residential. Southgate Stream traverses this site and is located two blocks northwest of the Site. There have been no other zoning changes in this area since 1995, when the current zoning was instituted. New homes and short platting are occurring to the south and west of the Site in the LDR district. The initial zoning districts created and mapped for this area were not based upon an in-depth analysis of site specific conditions. Greater scrutiny of the site and neighborhood characteristics indicate that moving the C/LI boundary to 48th Avenue S., with conditions, meets the purpose of the C/LI zone. 4) The proposed amendment to the [Comprehensive Plan and] Zoning Map will be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhoods, nor be injurious to other properties in the vicinity in which the subject property is located. The request would extend the boundary line for the C/LI district to 48th Avenue S. A comparison of standards between the LDR and C/LI zones shows that the standards are larger for uses in the C/LI than for single family homes in LDR. Also, the standards for building in C/LI increase when the site is within 50 feet of LDR, which would be the case for the Site. Standards in the C/LI zone are in place to minimize impact and any nuisance to adjacent residential properties. No on -site hazardous substance processing, handling, or storage is allowed unless clearly incidental to the permitted use and is subject to state siting criteria. Performance standards are in effect in the C/LI for air quality, noise and SEPA compliance and environmental regulations for restoring and protecting environmentally sensitive resources. The proposed change would set a more logical boundary and not negatively impact the residential environment of 48th Avenue S. if access is limited to S. 134th Place. Compliance with the applicable C/LI and nonconforming standards will ensure the proposed use of the Site will not adversely affect or injure other properties in the vicinity.

PURPOSE STATEMENT: To provide safe and efficient movement of people and goods to, from, within, and through Tukwila. PURPOSE The Transportation Element establishes Tukwila's transportation goals and policies for the 20-year planning period. It provides direction for transportation decisions regarding annual plan updates, including: ❖ The Six -Year Transportation Improvement Plan (TIP); •S The Six -Year Capital Improvement Program and Financial Planning Model (CIP/FPM); $• The biennial budget; and ❖ Infrastructure Design and Construction Standards. It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic Plan. It also provides guidance for development review and approval, land use and zoning decisions, and continuing transportation and maintenance programs. The Transportation Element establishes a basis for decision -making that is consistent with Washing- ton's Growth Management Act, King County's Countywide Planning Policies, and the Puget Sound Regional Council's (PSRC) Transportation 2040. The specific requirements of each of these plans are fulfilled by the City of Tukwila Transportation Element Background Report (including a revised Travel Demand Memorandum dated December 30, 2016) of the Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and summarized herein. The Transportation Background Report, Walk and Roll Non -motorized Transportation Plan, Tukwila Transit Network Plan, Commute Trip Reduction (CTR) Program and Plan, Growth and Transportation Efficiency Center (GTEC) Plan, the annually -updated six -year Transportation Improvement Plan, six -year CIP/ FPM, and the budget are all adopted by reference in the Tukwila Comprehensive Plan. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-2 26 ELEMENT 13 TRANSPORTATION ISSUES Tukwila's diverse transportation system includes freeways, highways, arterial streets, access streets, bus, Tight rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails and neighborhood footpaths. In addition, Sea-Tac International Airport and Boeing Field provide air transportation for general, commercial and business aviation. The Duwamish River provides water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail transportation within and through the city. Future Tukwila transportation system additions include Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained in the Background Report (Fehr& Peers, May2O12). The major transportation issues facing Tukwila include the following: • Physical and geographic barriers that challenge connectivity throughout the City. Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City from each other, increasing emergency services response times and cost. Residents value quiet neighborhood streets that exist in an incomplete or disconnected street system. With relatively few "through" streets, many vehicles use the streets that do connect, burdening the adjacent properties and residents. The large volume of vehicles on through -streets also makes it more difficult to walk to destinations such as schools, libraries or shopping. • Limited funding to satisfy competing priorities. — Increasing connectivity is very costly given the need to acquire new rights -of -way, conducting engineering studies and design, and construction costs. — Criteria for grant funding are most often targeted to Tukwila's Urban Center or the Manufacturing/Industrial Center because these are the locations where significant employment and residential growth are planned and are supported by regional plans. — There are unmet needs in other areas of the City, including streets that do not meet City standards, and it is unlikely that the roads would be improved by new development in these already developed areas. • Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-3 27 ELEMENT 13 TRANSPORTATION GOALS, POLICIES AND STRATEGIES The Transportation Element supports the City's Land Use Element. It demonstrates how the City will maintain and preserve the existing network as well as address deficiencies, while demonstrating how planned growth will be accommodated over the next 20 years per the Office of Financial Management (OFM) and PSRC forecasts. The household and job forecasts for Tukwila are for an additional 47860 4,800 households and 27,67015,500 jobs by the year 2030 2031, with most of that occurring in the Southcenter, Tukwila International Boulevard and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs) based on the availability of vacant and redevelopable lands (Maps 13-1 and 13-2). Employment forecasts in the Transportation Element — and used for the Transportation Demand Model — that include 277670 15,500 additional jobs from 2010-2030 2031 are -newly -double -the 500 additional -jobs -by 2031 ) were updated in a revised transportation model run in 2016. The original Transportation Demand Model run in 2010 was developed using employment forecast information available at the time. Since then, the employment forecast has-been was revised downward significantly due to the effects of the great recession on the regional economy. In addition, current forecasts are based to a greater degree on adopted King County Growth Targets for Tukwila. The City will revise the employment forecast and land use assumptions in the Transportation Element for consistency with land use -related elements and adopted growth targets during the next scheduled Transportation Demand Model update in 2016. GOAL 13.1 GENERAL Tukwila's transportation network provides for safe and efficient movement of people and goods to, from, within, and through Tukwila. GENERAL TRANSPORTATION POLICIES 13.1.1 Prioritize safety in an ongoing monitoring program. 13.1.2 Focus on transportation efficiency by maximizing the movement of people with streets that are designed to be safe for all transportation modes, accommodating existing land uses while designing for the future. 13.1.3 Balance travel efficiency, safety and quality -of -life in residential areas through creative roadway design.

PSRC's review noted that the employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. The discrepancy in the land use growth allocation occurred because the City of Tukwila updated the Transportation Element between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008-2009 recession and resulting slowdown in the real estate market. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. In response to this comment, the City hired Fehr & Peers to reallocate land use growth to be consistent with current PSRC Land Use Vision and to re -run the City's travel demand model. Key findings include: • The 2031 forecasted traffic volumes are not expected to grow as much within the City compared to the previous analysis (VMT is lower by three percent). • Most of the forecasted traffic volume decreases are in the Tukwila South area, where growth is not as rapid as was previously anticipated and where rnost of the employment growth was reduced. 1001 4th Avenue Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com L. Benjamin July 28, 2017 Page 2 of 2 • No changes are recommended to the proposed transportation capital improvement projects. Most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks. The large roadway projects to facilitate growth in Tukwila South were complieted by the developer in the 2010-2012 timeframe. Attached is a memo detailing the analysis to reallocate land use growth to be consistent with current forecasts, as well as two maps that illustrate the distribution of household and employment growth by 2031 within the City.

Sincerely, FEHR & PEERS CA/1-wvAv, Carmen Kwan Transportation Engineer/Planner SE16-0498 Attachment: • Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments Memo A FEHR4 PEERS MEMORANDUM Date: December 30, 2016 To: Robin Tischmak and Bob Giberson, City of Tukwila From: Carmen Kwan and Chris Breiland, Fehr & Peers Subject: Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments 5E16-0498 The Puget Sound Regional Council (PSRC) reviewed the City of Tukwila's draft Comprehensive Plan Elements in 2013 and identified that the land use growth forecast by 2031 in the Transportation Element was higher than current PSRC growth assumptions. In response to this comment, the forecast land use growth was revised to be consistent with PSRC assumptions and the City's travel demand model was re -run. This document details the analysis process and summarizes the new model results. The transportation capital improvement projects previously proposed were also reviewed to identify if any changes in the project list would be necessary based on the new growth forecasts. BACKGROUND The City of Tukwila updated the Transportation Element of the Comprehensive Plan between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008- 2009 recession and resulting slowdown in the real estate market nationwide. In general, the earlier PSRC land use forecasts predicted more growth by 2031 than the current (2016) land use forecasts. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. The rest of this memorandum describes the method used to align the Transportation Element growth forecasts with the rest of the Comprehensive Plan. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax. (206) 576-4225 www.fehrandpeers.com City of Tukwila December 30, 2016 Page 2 of 5 ANALYSIS METHODOLOGY The previous analysis completed for the Transportation Element assumed a growth of 27,665 jobs and 4,905 households by 2031. PSRC's review noted that this employment growth for the City of Tukwila is almost double the current forecast of 15,500job growth between 2010 and 2031. PSRC also forecasts a slightly lower number of households in the city by 2031 (4,800 new households). Land Use Revision In response to these comments, the 2031 land use assumptions were revised and the City's travel demand model was re -run to evaluate how traffic forecasts would change from the previous 2031 analysis (prepared with the higher growth forecasts). Key assumptions are listed below: • Land use forecasts were revised to match the Land Use Vision (LUV.1) Dataset, the most recent land use forecasts released by the PSRC in September 2015. • Land use growth assumptions in the Southcenter Subarea of Tukwila remained relatively consistent with the Southcenter Regional Growth Center EIS analysis prepared in 2014. Growth was adjusted elsewhere in the City based on the LUV.1 Dataset. A summary of the assumed land use growth is presented in Table 1. The revised 2031 forecasts show that the land use assumptions are consistent with PSRC growth assumptions of 4,800 households and 15,500 jobs between 2010 and 2031. The revised 2031 land use has a decrease of 105 households and 14,140jobs compared to the previous analysis. Land use growth assumptions by TAZ are in Attachment A. TABLE 1.

City of Tukwila December 30, 2016 Page 3 of 5 MODELING RESULTS The City's travel demand model was re -run with the revised land use growth assumptions described earlier. An example travel demand model difference plot of the change in PM peak hour traffic volume per travel lane is shown in Figure 1. The green bars show a decrease in vehicle traffic and the red bars show an increase in vehicle traffic compared to the previous 2031 analysis. FIGURE 1. 2031TRAVEL DEMAND MODEL DIFFERENCE PLOT Source: Fehr & Peers, 2016. City of Tukwila December 30, 20,16 Page 4 of 5 While there is some model "noise" in the difference plot results where some routes have minor increase or decrease in vehicle volumes compared to before, the overall observations from the new travel model runs are summarized below. • The 2031 forecasted traffic volumes are not expected to grow as much within the City of Tukwila compared to the previous analysis. The slightly lower vehicle traffic growth is reasonable based on the reduction of approximately 14,100 jobs and 100 households throughout the City by 2031 compared to the previous analysis. The new 2031 model run's slightly lower traffic growth is minor as there is only a three percent decrease in vehicle - miles -travelled (VMT) on City streets during the PM period compared to the previous analysis (excluding freeways). • Most of the forecasted traffic volume decreases are south of S 180th Street. This is expected as the growth near Southcenter Regional Growth Center did not change much from the earlier analysis, and most of the employment reduction was in the Tukwila South area, where growth is not as rapid as was anticipated in the earlier forecasts. Overall, City staff felt this area had the least amount of momentum for growth compared to the rest of the City. • No changes are recommended to the proposed transportation capital improvement projects. A review of the previously recommended projects was completed based on the new model run results. In general, all the projects identified in the Transportation Element are recommended to remain because: o Most of the street extension projects were recommended to reduce block size and improve mobility for all modes. These projects would improve street grid connectivity, improve the walkability by breaking up large blocks, and potentially improve emergency response times. While there is a minor decrease in vehicle volumes in the new model run compared to the previous results, projects are recommended to remain to help the City achieve the desired urban form and street network connectivity pattern. o Intersection improvements at various intersections such as adding turn pockets are still recommended as the model shows that turning volumes that triggered the additional turn lanes will not decrease enough to eliminate the need for the additional lanes. o Many projects were identified to enhance pedestrian and/or bicycle facilities. While growth is slightly lower with the new land use forecasts, the need for a City of Tukwila December 30, 2016 Page 5 of 5 comprehensive and connective pedestrian and bicycle network is not altered by the revised land use forecasts. CONCLUSION A new travel model run was completed with revised 2031 land use growth reallocated to be consistent with PSRC's vision of 15,500 new jobs and 4,800 new households between 2010 and 2031 in Tukwila. Based on the results of the new travel model run, no changes to the Transportation Element project list are recommended. While the traffic growth by 2031 is not expected to be as high as the previous analysis (VMT is lower by three percent), most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks.

The update included a traffic modeling effort based on projected household and employment growth throughout the City until the year 2030. These growth numbers were determined at a regional level and provided to each jurisdiction for use in long range planning efforts. After Tukwila's updated element was adopted, the Puget Sound Regional Council (PSRC) developed revised growth projections that reflected the reduced economic activity due to the 2008-2009 recession. These numbers showed a small reduction in projected household growth and a significant reduction in projected employment growth (nearly 50%). The other elements of the Tukwila Comprehensive Plan were updated in later phases using the revised PSRC numbers and a 2031 time horizon, leading to an internal discrepancy in the Plan. Tukwila received conditional approval for its Plan update in 2016 with the requirement that the discrepancy be addressed through adoption of an updated Transportation Element by December of 2017. COMPREHENSIVE PLAN REVIEW CRITERIA 1) Describe how the issue Is addressed in the comprehensive Plan. If the issue is not adequately addressed, is there a need for it? The Transportation Element update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The lower employment projections resulted in estimates of lower vehicle miles traveled and no lowering of levels of service (COS). As a result of this change, no goals, policies, or capital improvement project changes are proposed as part of this action. The changes involve text edits to the narrative and updated maps. 2) If the issue is not adequately addressed in the Comprehensive Plan, is there a need for the proposed change? Under the original Background Report and 2010 model run, higher projections were received from PSRC. Tukwila had planned to accommodate higher household and employment growth than currently projected. Much of this growth was anticipated in the Tukwila South area, which remains largely undeveloped. The timeline for development there is unclear, though at least some Is likely to occur within the 2031 time horizon of the current Comprehensive Plan. The new traffic model run using the 2031 forecasts provides Internal consistency throughout the Comprehensive Plan and is being documented in the revised language and maps. Page 1 of 5 Exhibit A 3) Is the proposed change the best means for meeting the identified public need? What other options are there for meeting the identified public need? As part of the conditional certification process the City of Tukwila agreed to the following PSRC conditions: 1. Tukwila City Council adoption of a plan of work that addresses the condition identified in the certification report by May 31, 2016. Adopted 5/2/2016 2. Submission of a draft amended comprehensive plan and supporting documents that address the condition to PSRC for review and comment in advance of adoption. Sent August 14, 2017, PSRC has confirmed that these changes are adequate to meet the condition.. 3. Once the condition is adequately addressed, submission of adopted amended comprehensive plan and supporting documents by December 31, 2017 for review and certification by PSRC. 4) Will the proposed change result in a net benefit to the community? Gaining full certification for Tukwila's Comprehensive Plan will maintain the City's eligibility for PSRC and Regional Transportation Improvement Program funding. In reviewing Comprehensive Plan criteria, staff concludes that the proposed update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The projected traffic levels are lower under the revised employment levels and therefore no impacts are expected that were not already addressed under the original Element. As a result of this change, no goals, policies or capital improvement project changes are needed or proposed as part of this action. Flower Power Comprehensive Plan and Zoning Map Change Background This application is part of the 2016-2017 annual docket for amendment of the Comprehensive Plan. The purpose of an annual docket is to ensure that changes to the Comprehensive Plan are only considered once a year and that they are considered concurrently and so the cumulative impact of the proposals can be determined. The applicant is seeking changes In the Comprehensive Plan and Zoning maps for a 28,270-square foot lot located at 13407 48th Ave. S., Tukwila, Washington, King County tax parcel no, 262.320-0028 (the "Site") from low Density Residential (LOR) to Commercial Light Industrial (C/LI) for the following reasons: 1. As the resident of the home located on the Site, he thinks that the noise from the LINK trains is unacceptable for a residential setting; 2. As the property owner of the Site since 1992, he has had much flooding from the Southgate stream that travels along the south and east sides of the Site and along the edge of the existing Page 2 of Exhibit A home. A 2003 City project to install a high flow by-pass upstream of the site does not alleviate all flooding, which continues during rain storms. 3. He owns and operates a business growing bean sprouts, which he sells commercially and that is being displaced by a King County levee project in Kent. He would like to relocate his operation to this Site where he currently lives. C/LI zoning on the Site would allow the hydroponic growing of the bean sprouts and their assembly and distribution. This non -project proposal is a quasi-judicial change to the land use designation on the Tukwila Comprehensive Plan and Zoning maps. If the zoning is changed, any C/LI use would be permitted subject to all City regulations; however, the applicant has stated his intent to construct a new commercial/light industrial building for his hydroponic bean sprout business. The applicant submitted an existing site plan and a proposed site plan as an example of his intent. COMPREHENSIVE PLAN AND ZONING MAP CHANGE CRITERIA 1) The proposed amendment to the [Comprehensive Plan and] zoning map is consistent with the goals, objectives, and policies of the Comprehensive Plan. Comprehensive Plan policies discuss having identifiable boundaries for residential districts. Access and orientation of lots has an impact on the quality of the residential environment. Most single-family home owners prefer to see the same use across the street from them as evidenced by City policy of "identifiable neighborhood boundaries." The Site's existing orientation is to S. 134th Place, which is a commercial local access street, rather than to 48th Avenue S., which is a residential local access street. The existing structure, a home, sits at an elevation that is significantly below 48th Avenue 5. which would make access via 48th Avenue more difficult, expensive, and potentially more impactful to Southgate stream than access via 134th Place. Thus, because access via S. 134th Place is preferred, including this Site in the C/LI district would be a logical boundary. In addition, the Comprehensive Plan's natural environment policies would support the redevelopment of the Site and the restoration of the buffer for the Southgate stream. A CAI designation would potentially encourage the redevelopment of the Site. The Flower Power application for a map change is supported by the following Comprehensive Plan policies: The Residential Neighborhoods Element goal: A land use pattern that encourages o strong sense of community by grouping compatible and mutually supportive uses and separating Incompatible uses. (Goal 7.1) The policies of that Element then speak about recognizable boundaries: Maintain a comprehensive land use map that supports the preservation and enhancement of single family and stable multi family neighborhoods; eliminates incompatible land uses; and clearly establishes applicable development requirements through recognizable boundaries. (Policy 7.1.1 ) Page 3 of 5 Exhibit A The C/LI zoned lot along the Site's north edge, 4625 S. 134th Place, is improved with an older house, but the lot is being used for parking for Hoiaday Park, which is the business located across S. 134th Place street (and in a C/Ll district)) blurring the boundaries for these distinct zoning districts. The Natural Environment Element has the following goal: Watercourses and their buffers, .... are protected from encroachment and degradation and improved through mitigation, enhancement, and restoration projects. (Gool4.6) It is difficult to see the developrnent on the Site because the vegetation covers the site and stream; however, the existing structure was constructed over 7 decades ago in the stream buffer prior to enactment of the City's environmental regulations. A relevant Economic Development Element policy is: Promote and preserve economic use of industrial lands outside the MIC through appropriate buffering requirements and use restrictions. (Economic Development Policy 2.1.16) The applicant also lists an Economic Development Policy related to promoting and supporting business formation, expansion and the importance of the City's entrepreneurs and small businesses in creating jobs. The applicant references several policies in the Community Image and identity Element related to local food production and urban agriculture. 2) The proposed amendment to the Zoning Map is consistent with the scope and purpose of this title (the Zoning Code) and the description and purpose of the zone classification applied for. The purpose of the Commercial/Light Industrial (C/LI) designation and zone are, "...to provide for areas characterized by a mix of commercial, office, or light industrial uses. The standards are intended to promote viable and attractive Commercial and industrial areas.'' (TMC 18.30.010) The Site is similar in character to the adjacent C/LI properties to the north in that It has frontage along S. 134th Place, has Southgate stream along its street frontage, has frequent truck traffic along it's frontage, and is similar in topography. The applicant discusses developing a commercial/light industrial business that would be consistent with the proposed Zone and the Site contains the characteristics of similar C/LI properties. The proposed C/Li zoning would allow the applicant to relocate his existing business, which is a hydroponic bean sprout grow operation, to the City of Tukwila from the City of Kent. His business is currently housed in a warehouse in Kent that is being displaced due to a Green River Levee project. The C/LI zone allows commercial greenhouses with no size limit whereas in LDR, greenhouses are allowed up to 1,000 square feet.) In contrast, the purpose of the Low Density Residential (LDR) district is ",.. to provide low -density family residential areas together with a full range of urban infrastructure services in order to maintain stable residential neighborhoods, and to prevent intrusions by incompatible land uses." (TNMC 18.10.010) Except for the Site, the zoning designation of all properties fronting along S. 134th Place are C/LI. Page 4 of Exhibit A The Site is rectangular with the narrow portion of the lot is along 48th Avenue S and the long side of the lot is along 134th Place. The Zoning Code stipulates that lot frontage shall be "considered the narrowest part of the lot that abuts a street." Because the Site is a corner lot and because there is a significant grade difference between 48th Avenue S. and the Site, access to the Site and overall orientation of the property is currently from S. 134th Place. 3) There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the Zoning [and Comprehensive Plan] Map. In 2007, a Type 2 Special Permission for a buffer reduction was granted to the property owner of 4501 5. 134th Place. Sound Transit acquired and in 2009 consolidated 11 residentially zoned parcels across 48th Avenue S and diagonally across the street from the Site. There was a Comprehensive Plan and Zoning map change in 2010 when 4300 S. 133rd S. was rezoned from C/LI to Medium Density Residential. Southgate Stream traverses this site and is located two blocks northwest of the Site. There have been no other zoning changes in this area since 1995, when the current zoning was instituted. New homes and short platting are occurring to the south and west of the Site in the I_DR district. The initial zoning districts created and mapped for this area were not based upon an in-depth analysis of site specific conditions. Greater scrutiny of the site and neighborhood characteristics indicate that moving the CAI boundary to 48th Avenue S., with conditions, meets the purpose of the C/LI zone. 4) The proposed amendment to the [Comprehensive Plan andj Zoning Map will be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhoods, nor be injurious to other properties in the vicinity in which the subject property is located. The request would extend the boundary line for the CAI district to 48th Avenue 5, A comparison of standards between the LDR and C/Lt zones shows that the standards are larger for uses in the CAI than for single family homes in LDR. Also, the standards for building in C/LI increase when the site is within 50 feet of LDR, which would be the case for the Site. Standards in the C/LI zone are in place to minimize impact and any nuisance to adjacent residential properties. No on -site hazardous substance processing, handling, or storage is allowed unless clearly incidental to the permitted use and is subject to state siting criteria. Performance standards are in effect in the C/LI for air quality, noise and SEPA compliance and environmental regulations for restoring and protecting environmentally sensitive resources. The proposed change would set a more logical boundary and not negatively impact the residential environment of 48th Avenue S. if access is limited to S. 134th Place. Compliance with the applicable C/LI and nonconforming standards will ensure the proposed use of the Site will not adversely affect or injure other properties in the vicinity.

' ELEMENT 13 TRANSPORTATION TRANSPORTATION WHAT YOU WILL FIND IN THIS CHAPTER: • A description of the existing transportation network in Tukwila; • A discussion of how transportation planning and land use are related; • A discussion of how demand on the transportation network is managed; and • Goals and Policies for providing adequate levels of service. PURPOSE STATEMENT: To provide safe and efficient movement of people and goods to, from, within, and through Tukwila. PURPOSE The Transportation Element establishes Tukwila's transportation goals and polities for the 20-year planning period. It provides direction for transportation decisions regarding annual plan updates, including: • • C. The Six -Year Transportation Improvement Plan (TIP); The Six -Year Capital Improvement Program and Financial Planning Model (CIP/FPM); The biennial budget; and Infrastructure Design and Construction Standards. It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic Plan. It also provides guidance for development review and approval, land use and zoning decisions, and continuing transportation and maintenance programs. The Transportation Element establishes a basis for decision -making that is consistent with Washing- ton's Growth Management Act, King County's Countywide Planning Policies, and the Puget Sound Regional Council's (PSRC) Transportation 2040. The specific requirements of each of these plans are fulfilled by the City of Tukwila Transportation Element Background Report (including a revised Travel Demand Memorandum dated December 30, 2016) of the Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and summarized herein. The Transportation Background Report, Walk and Roll Non -motorized Transportation Plan, Tukwila_ Transit Network Plant Commute Trip Reduction (CTR) Program and Plan, Growth and Transportation Efficiency Center fGTEC) Plan, the annually -updated six -year Transportation Improvement Plan, six -year CIP/ FPM, and the budget are all adopted by reference in the Tukwila Comprehensive Plan. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-2 ELEMENT 13 TRANSPORTATION ISSUES Tukwila's diverse transportation system includes freeways, highways, arterial streets, access streets, bus, light rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails and neighborhood footpaths. In addition, Sea-Tac International Airport and Boeing Field provide air transportation for general, commercial and business aviation. The Duwamish River provides water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail transportation within and through the city. Future Tukwila transportation system additions include Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained in the Background Report (Fehr& Peers, May2012). The major transportation issues facing Tukwila include the following: ♦ Physical and geographic barriers that challenge connectivity throughout the Cuty. Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City from each other, increasing emergency services response times and cost. Residents value quiet neighborhood streets that exist in an incomplete or disconnected street system. With relatively few"through"streets, many vehicles use the streets that do connect, burdening the adjacent properties and residents. The large volume of vehicles on through -streets also makes it more difficult to walk to destinations such as schools, libraries or shopping. • Limited funding to satisfy competing priorities. — Increasing connectivity is very costly given the need to acquire new rights -of --way, conducting engineering studies and design, and construction costs, — Criteria for grant funding are most often targeted to Tukwila's Urban Center or the Manufacturing/Industrial Center because these are the locations where significant employment and residential growth are planned and are supported by regional plans, — There are unmet needs in other areas of the City, including streets that do not meet City standards, and it is unlikely that the roads would be improved by new development in these already developed areas. • Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-3 ELEMENT 13 TRANSPORTATION GOALS, POLICIES AND STRATEGIES The Transportation Element supports the City's Land Use Element. It demonstrates how the City will maintain and preserve the existing network as well as address deficiencies, while demonstrating how planned growth will be accommodated over the next 20 years per the Office of Financial Management (©FM) and PSRC forecasts. The household and job forecasts for Tukwila are for an additional 4860 4,800 households and 27;670-15,500 jobs by the year 2030 2031, with most of that occurring in the Southcenter, Tukwila International Boulevard and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs) based on the availability of vacant and redevelopable lands (Maps 13-1 and 13 2). Employment forecasts in the Transportation Element - and used for the Transportation Demand Model - that include 27 6 015,500 additional jobs from 2010 2030 2031 we -newly -double -the w arget nd-forec-acts-fep sent -(he 3-5;500 additional -jobs -by 2034-) were updated in a revised transportation model run in 2016. The original Transportation Demand Model run In 2010 was developed using employment forecast information available at the time. Since then, the employment forecast has-been was revised downward significantly due to the effects of the great recession on the regional economy. In addition, current forecasts are based to a greater degree on adopted King County Growth Targets for Tukwila. The City will revise the employment forecast and land use assumptions in the Transportation Element for consistency with land use -related elements and adopted growth targets during the next scheduled Transportation Demand Model update in 2016. GOAL 73.1 GENERAL Tukwila's transportation network provides for safe and efficient movement of people and goods to, from, within, and through Tukwila. GENERAL TRANSPORTATION POLICIES 13.1.1 Prioritize safety in an ongoing monitoring program. 13.1.2 Focus on transportation efficiency by maximizing the movement of people with streets that are designed to be safe for all transportation modes, accommodating existing land uses while designing for the future. 13.1.3 Balance travel efficiency, safety and quality -of -life in residential areas through creative roadway design.

The Countywide Planning Policies are a series of policies that address growth management in King County. The Countywide Planning Policies provide a county -wide vision and create a framework each jurisdiction can use when developing its own comprehensive plan. HOW DO THE COUNTYWIDE PLANNING POLICIES AFFECT TRANSPORTATION PLANNING IN TUKWILA? Because each city's comprehensive plan must be consistent with the overall County policy framework, Tukwila has incorporated some of the Countywide Planning Policies into this element. For example, the Countywide Planning Policies identify protection of the natural environment and transportation accessibility for non -drivers as regional priorities. The City has established policies 13.1.5 and 13.1.8 to address these needs.

TUKWILA COMPREHENSIVE PLAN - 201$ PAGE 13-7 E.EMENT 13 TRANSPORTATION STREET CLASSIFICATIONS For street design and operation purposes, engineers classify streets into four categories: principal arterials, minor arterials, collector arterials, and local access streets. These four categories group streets according to whether they prirnarily provide access to properties or are purely for mobility. The differences In function result in different street widths, number of curb cuts/driveways allowed, speed limit, traffic controls, and other similar design and operation features.

Property developments and improvements in commercial areas shall provide direct pedestrian access from sidewalks to buildings, as well as to, from and between parking areas. 13.2.6 Incorporate proportionately greater neighborhood -enhancing elements in collector, minor arterial, and principle arterial design. These elements include collector lanes, wider sidewalks, separated sidewalks, and curbline trees. 13.2.7 Design residential access streets to provide at least the minimum capacity for emergency access and for slow traffic. 13.2.8 Design collector arterials with a two -travel -lane, local access road design to encourage slow but steady speeds. 13.2.9 Design streets, including retrofit projects, to accommodate a range of motorized and non -motorized travel modes in order to reduce injuries and fatalities, to provide access to services, and to encourage non -motorized travel. The design should include well-defined, safe and appealing spaces for pedestrians and bicyclists. 13.2.10 Evaluate street improvement projects for the inclusion of features that support the Complete Streets policy and the Walk and Roll Plan in order to encourage walking, bicycling and transit use. 13.2.11 Design intersections and sidewalks to promote pedestrian safety and foster walking as a viable mode of transportation. 13.2.12 include roadside plantings whenever feasible for street and road improvement projects on slopes to help mitigate the land used for roadway and sidewalk improvements. TUKWILA COMPREHENSIVE PLAN - 201S PAGE 13-9 ELEMENT TRANSPORTATION WHAT IS TRANSPORTATION CONCURRENCY? The Washington State Growth Management Act requires the City to ensure that transportation programs, protects and services needed to serve growth are regionally coordinated, and are in place either when new development occurs or within six years. This is done to make sure the City can provide the transportation improvements needed to maintain its adopted standards of service and so that conditions do not degrade with the addition of the new households and workers in the City. Implementation Strategies f + implement sidewalk ordinance. Implement subdivision ordinance. Implement Street Network Plan. Emergency vehicle criteria in street design standards. Prioritize neighborhood quality design features when reducing street facilities (e.g., removal of one lane of parking before removal of sidewalk). Traffic Calming Program. : Develop methods to incentivize and encourage coordinated development between adjacent commercial properties, including shared driveways and direct vehicular access between parking lots. LEVEL OF SE VOCF The projected growth numbers in Tukwila and surrounding areas were used in the Background Report for the Transportation Element of the Comprehensive Plan Update to anticipate traffic volumes and levels of service in 2030. The Level of Service (LOS) analysis is one of the ways the City plans and budgets for future transportation projects. The City balances the fiscal constraints of its financing plan for transportation programs and projects with planned growth and existing needs. To do this, Tukwila monitors LOS on arterial streets to examine the existing performance of the system and anticipated impacts of planned land use growth, to determine what adjustments will need to be made to maintain adopted LOS standards concurrent with new development. Properly applied and monitored, LOS standards for the transportation network ensure that mobility, vitality and quality of life for the city is maintained. For the 2030 planning horizon, significant new capacity will be required to accommodate future growth throughout the city, although the majority of the project capacity needs are In the Southcenter area. TUKWiLA COMPREHENSIVE PLAN - 2015 PAGE 13-10 ELEMENT- L TRANSPORTATION Traditionally, LOS has been used to evaluate vehicular flow with little regard to other forms of transportation such as pedestrians, bicycles and transit. Building upon Tukwila's Walk and Roll Plan, the Complete Streets standard and Transit Network Plan, the City is working to develop a Multi -Modal Level of Service (MMLOS) to help balance transportation goals across all modes of transportation. The City has identified Transit Priority Corridors as part of an analysis done for the Transit Network Plan, and will continue to work closely with transit providers to achieve goals and policies related to transit service, to serve existing needs and to accommodate future growth. AUTOMOBILE LOS In many ways, the existing performance of Tukwila's transportation system reflects how performance has historically been evaluated —with a strong bias towards auto travel, Automobile LOS is focused on setting an acceptable level of delay drivers can expect along a corridor or at a particular Intersection. To see how the transportation system will function in the future, growth projections are incorporated into traffic models to determine future conditions along arterial streets and at intersections. Modeling results, along with a list of projects needed to rnaintain adopted LOS on arterial streets, are included in the Background Report. Tukwila's transportation system generally accommodates auto travel well, with just a handful of locations operating at a poor automobile LOS. NON -MOTORIZED LOS LOS for pedestrians and bicyclists is focused on measuring factors that impact the safety and comfort of pedestrians and bicycles rather than quantifying congestion and delay. In 2007 and 2008, Tukwila collected data on existing conditions for pedestrians and bicycle facilities on all arterial streets, using the 2010 Highway Capacity Manual's Multi -Modal Level of Service (2010 HCM MMLOS) methodology. The 2010 HCM MM LOS did not produce results that could be used in a similar fashion as the auto- mobile LOS, which categorizes minutes of delay into an A-F rating. The City needs to create or find a system for quantifying the conditions of pedestrian and bicycle facilities so that a goals -based ap- proach to prioritizing these projects is achieved. The City will continue to customize a non -motorized level of service measure to help achieve the City's vision of a more balanced mix of mobility options. TRANSIT LOS Transit service, both frequency and time -span of service, is an important aspect of a healthy transportation network. The City uses the Transit Capacity and Quality of Service Manual, published by the Transportation Research Board, as a methodology to measure level of service for transit. This recommended level of service methodology is included In the City's Transit Network Plan (Perteet 2004). The Plan identified service frequency needs for the City and facility improvements necessary for robust and effective transit service. Tables 13-1 and 13-2 illustrate LOS standards for transit service frequency and hours of service, respectively.

At this time, the City is not the owner/operator of a transit service, therefore a minimum level of service standard cannot be enforced. However, Tukwila will encourage all transit providers to achieve and maintain a minimum LOS C and focus service within Tuukwila's Transit Priority Corridors. Tukwila's goal is to have transit service every 15-20 minutes throughout most of the day on its Transit Priority Corridors, including early evening. The following is an assessment of existing transit service on Tukwila's Transit Priority Corridors: D King County Metro identifies eight corridors in Tukwila on which it has set target service levels (see Table 13-3) Other bus routes not identified in Table 13-3 also currently serve Tukwila.

However, most corridors are not served with frequent service throughout the day with the exception of the Rapid Ride routes, including Rapid Ride A Line and the planned Rapid Ride F Line. D Link Light Rail, providing service between SeaTac Airport and Seattle, currently meets the City's LOS standard both in terms of frequency and time -span. (Sound Transit2013 Service Implementation Plan, p. 21) 1 There are currently nine northbound and nine southbound Sounder Trains providing service between Seattle and Lakewood, with a stop in Tukwila on the Sounder South Line. The Sounder South Line represents 90% of total Sounder ridership. Four new South Line round trips were implemented in September 2013, creating a schedule that includes 20-minute headways for the peak hour of service, which will bring the South Line Into conforrnance with the City's LOS in terms of frequency during the peak hour, but will not meet the City's LOS in terms of time span.

TRANSPORTATION The City of Tukwila strives to collaborate and cooperate with the region's transit providers in order to have convenient transit service to support and complement adjacent land uses. The goal of increasing overall transit ridership within the City of Tukwila drives the need for both service and capital improvements. Transit speed and reliability, improved passenger amenities, and access to transit service are all crucial for attracting and maintaining transit riders. King County Metro provides bus service throughout the City of Tukwila. Twelve different routes provide intra Tukwila service and direct service to Burien, Kent, Auburn, Seattle, Renton and West Seattle. Existing Route 140 is planned to be upgraded to Rapid Ride bus rapid transit, with associated facilities, In 2014. At this time, Sound Transit does not serve any destinations in Tukwila with Regional Express Bus service. Sounder, the regional commuter rail service, has a stop in Tukwila at theTukwila Station, as does Amtrak regional passenger rail service. Sound Transit Link Light Rail is located in Tukwila, with service from SeaTac Airport to downtown Seattle. Extensions of Link Light Rail are planned to the north, south, and east, To achieve the goal of increased transit frequency and time span of service toTukwila's activity centers and regional destinations, a multi -hub system and Transit Priority Corridor Classifications were developed, as shown on Map 13-3. Transit Priority Corridors are those corridors where transit service currently exists. Activity centers are tied together by the Transit Priority Corridors, and include the Tukwila International Boulevard Link Light Rail Station, the Tukwila Commuter Rail/Amtrak Station, an improved Southcenter Transit Center, and a new link connecting the Tukwila Commuter Rail/Amtrak Station to areas near Westfield Mall at Southcenter. Improved routes and frequency feed into this multi -hub concept. Transit Priority Corridor Classifications identify transit corridor types by function, ideal transit operational characteristics, optimal adjacent land uses, and supporting physical design features of the public infrastructure. The classification system is designed to be flexible and assist quality decision -making. An inventory of present transit routes is contained in the Background Report. Recommendations for service changes and infrastructure needs are contained in the Tukwila Transit Plan. King County Metro and Sound Transit control changes to routes.

TUKWILA COMPREHENSIVE PLAN - 201S PAGE 13.19 ELCMENT 13 TRANSPORTATION TRAKSPOGITATION DEMAND MANAGEMENT Transportation Demand Management (TDM) emphasizes the movement of people and goods, rather than vehicles, by providing transportation alternatives to driving. TDM benefits the community by maximizing the efficiency of existing infrastructure, and limiting the impacts of excessive traffic in neighborhoods by promoting transportation options such as carpooling, vanpooling, transit, walking, biking, teleworking and flexible work hours. Reducing vehicle trips limits air and water pollution and supports the City's commitment to reduce greenhouse gas emissions. Tukwila's TDM activities are directed at employers, workers, business owners, residents and visitors. Tukwila adopted a Commute Trip Reduction (CTR) Plan in 2008 that sets goals and implementation strategies for large employers to reduce drive -alone trips and vehicle miles traveled. Tukwila adopted a Growth and Transportation Efficiency Center (GTEC) Plan in 2008 to set the stage for focused TDM activities in Tukwila's urban center. The CTR Plan and GTEC Plan provide locally - adopted mode -split goals for Tukwila's Southcenter/Urban Center and the Manufacturing and Industrial Center (MIC). The City's six -year mode -split targets for the Urban Center are 65.7% drive -alone trips and 34.3% non -drive -alone trips, as defined in the City's GTEC Plan. Within the Urban Center, the City will also try to meet its GTEC goals with a targeted Vehicle Miles Travelled (VMT) rate of 13.05. In the MIC, mode -split goals are 70% drive -alone, consistent with the remainder of the city. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-20 ELEMENT TRANSPORTATION GOAL 13.5 TRANSPORTATION DEMAND MANAGEMENT Support transportation system improvements and programs which encourage transit use, high -occupancy vehicle trips and non -motorized transportation to reduce single -occupancy vehicle trips, vehicle miles traveled, traffic congestion, and greenhouse gas emissions.

' Promote the use of drive -alone alternatives through social media, RidleShareOnline.com, community outreach, and offering assistance with parking management. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-21 ELEMENT TRANSPORTATION TOROZED TRANSPORTATION Tukwila adopted its first non -motorized transportation plan - the Walk and Roll Plan - in 2009, as well as a Complete Streets policy. This policy requires all new City transportation improvement projects to provide appropriate accommodation for pedestrians, bicyclists, transit riders and persons of all abilities, while promoting safe operation for all users„ The Walk and Roll Plan includes an inventory of existing non -motorized facilities, including bike lanes, trails, sidewalks and pedestrian footpaths (see Map 13-4). The Plan also identifies projects to guide City implementation of a safe and complete non -motorized network. These projects are made up of (1) a list of missing sidewalk segments and a method of prioritizing which missing segments should be constructed first, (2) trail projects to expand the existing system of non -motorized neighborhood connections, and (3) a backbone network of Bicycle Friendly Routes - existing and planned on -street facilities and trail projects that represent a bicycle network connected to local and regional destina- tions, as well as existing and planned bicycle -friendly routes in adjacent Jurisdictions (see Map 13-5). The Walk and Roll Plan commits the City to promoting programs that support and encourage biking, walking, commute trip reduction activities, and the City's annual participation in the regional bicycle and pedestrian count. GOAL 13.6 NON -MOTORIZED TRANSPORTATION Tukwllas non -motorized transportation network is safe and comfortable, provides local and regional connections to neighborhoods and activity centers, and makes cycling and walking viable and enjoyable forms of transportation and recreation. POLICIES 13.6.1 Consider and provide for all users of the roadway, including pedestrians and bicyclists, as appropriate, when new streets and street improvements are made. 13.6.2 Allocate funds to the Residential Street Fund in order to build sidewalks on residential local access streets. 13.6.3 Include pedestrian and bicycle improvements in street improvement projects, as appropriate.

TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-26 ELEMENT 1 TRANSPORTATION G C EEIG 1T, RAM ,WATER, AND NB !RAW] PORTA ION Tukwila's Urban Center and Manufacturing and Industrial Center (MIC) include retail, commercial and industrial businesses which serve the region. Railroad tracks owned by the Burlington Northern Santa Fe (BNSF) and Union Pacific (UP) railroads run north/south through Tukwila. These rail networks carry international and domestic cargo to inland markets, and serve the Port of Seattle to the north and the Port of Tacoma to the south. Industrial railroad spurs, operated and controlled by the railroad companies and private property owners, are located in the Southcenter and MiC area. BNSF has a multi -modal storage yard in the Manufacturing and Industrial Center in northern Tukwila. Both Amtrak and Sound Transit's Sounder Commuter Rail use the BNSF tracks. Given Tukwila's location at the crossroads of two major interstate highways, and the prevalence of manufacturing, warehousing and commercial activities in the City, many streets experience high truck volumes. The streets with the highest truck traffic are West Valley Highway south of Strander Boulevard, interurban Avenue South north of SR 599, and East Marginal Way South north of Boeing Access Road. The portion of the Duwamish River in Tukwila north of the Turning Basin is located within the City's Manufacturing and industrial Center and is accessible to shipping activity. The river remains inaccessible to shipping activity south of the Turning Basin, where it can be accessed by small water craft, kayaks and canoes only. King County International Airport, also known as Boeing Field, is located in northern Tukwila at the City's border with Seattle, and is one of the busiest primary non -hub airports In the nation. The airport serves small commercial passenger airlines, cargo carriers, private aircraft owners, helicopters, corporate jets, and military and other aircraft. It is also home to approximately 150 tenant businesses, including the Boeing Company operations. The Museum of Flight is allso located there and attracts a large number of visitors to the area. Sea-Tac Airport, the State's largest airport, is located within a mile of Tukwila city limits. The airport is a large employer for Tukwila residents, and its operations support manyTukwlia businesses.

The update included a traffic modeling effort based on projected household and employment growth throughout the City until the year 2030. These growth numbers were determined at a regional level and provided to each jurisdiction for use in long range planning efforts. After Tukwila's updated element was adopted, the Puget Sound Regional Council (PSRC) developed revised growth projections that reflected the reduced economic activity due to the 2008-2009 recession. These numbers showed a small reduction in projected household growth and a significant reduction in projected employment growth (nearly 50%). The other elements of the Tukwila Comprehensive Plan were updated in later phases using the revised PSRC numbers and a 2031 time horizon, leading to an internal discrepancy in the Plan. Tukwila received conditional approval for its Plan update in 2016 with the requirement that the discrepancy be addressed through adoption of an updated Transportation Element by December of 2017. COMPREHENSIVE PLAN REVIEW CRITERIA 1) Describe how the issue is addressed in the Comprehensive Plan. If the issue is not adequately addressed, is there a need for it? The Transportation Element update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The lower employment projections resulted in estimates of lower vehicle miles traveled and no lowering of levels of service (LOS). As a result of this change, no goals, policies, or capital improvement project changes are proposed as part of this action. The changes involve text edits to the narrative and updated maps. 2) If the issue is not adequately addressed in the Comprehensive Plan, is there a need for the proposed change? Under the original Background Report and 2010 model run, higher projections were received from PSRC. Tukwila had planned to accommodate higher household and employment growth than currently projected. Much of this growth was anticipated in the Tukwila South area, which remains largely undeveloped. The timeline for development there is unclear, though at least some is likely to occur within the 2031 time horizon of the current Comprehensive Plan. The new traffic model run using the 2031 forecasts provides internal consistency throughout the Comprehensive Plan and is being documented in the revised language and maps. Page 1 of 5 19 Exhibit A 3) Is the proposed change the best means for meeting the identified public need? What other options are there for meeting the identified public need? As part of the conditional certification process the City of Tukwila agreed to the following PSRC conditions: 1. Tukwila City Council adoption of a plan of work that addresses the condition identified in the certification report by May 31, 2016. Adopted 5/2/2016 2. Submission of a draft amended comprehensive plan and supporting documents that address the condition to PSRC for review and comment in advance of adoption. Sent August 14, 2017, PSRC has confirmed that these changes are adequate to meet the condition. 3. Once the condition is adequately addressed, submission of adopted amended comprehensive plan and supporting documents by December 31, 2017 for review and certification by PSRC. 4) Will the proposed change result in a net benefit to the community? Gaining full certification for Tukwila's Comprehensive Plan will maintain the City's eligibility for PSRC and Regional Transportation Improvement Program funding. In reviewing Comprehensive Plan criteria, staff concludes that the proposed update is a technical correction to the growth projections used in the Transportation Element that is needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The projected traffic levels are lower under the revised employment levels and therefore no impacts are expected that were not already addressed under the original Element. As a result of this change, no goals, policies or capital improvement project changes are needed or proposed as part of this action. Flower Power Comprehensive Plan and Zoning Map Change Background This application is part of the 2016-2017 annual docket for amendment of the Comprehensive Plan. The purpose of an annual docket is to ensure that changes to the Comprehensive Plan are only considered once a year and that they are considered concurrently and so the cumulative impact of the proposals can be determined., The applicant is seeking changes in the Comprehensive Plan and Zoning maps for a 28,270-square foot lot located at 13407 48th Ave. S., Tukwila, Washington, King County tax parcel no. 261320-0028 (the "Site") from Low Density Residential (LDR) to Commercial Light Industrial (C/LI) for the following reasons: 1. As the resident of the home located on the Site, he thinks that the noise from the LINK trains is unacceptable for a residential setting; 2. As the property owner of the Site since 1992, he has had much flooding from the Southgate stream that travels along the south and east sides of the Site and along the edge of the existing Page 2 of 5 20 Exhibit A home. A 2003 City project to install a high flow by-pass upstream of the site does not alleviate all flooding, which continues during rain storms. 3. He owns and operates a business growing bean sprouts, which he sells commercially and that is being displaced by a King County levee project in Kent. He would like to relocate his operation to this Site where he currently lives. C/LI zoning on the Site would allow the hydroponic growing of the bean sprouts and their assembly and distribution. This non -project proposal is a quasi-judicial change to the land use designation on the Tukwila Comprehensive Plan and Zoning maps. If the zoning is changed, any C/LI use would be permitted subject to all City regulations; however, the applicant has stated his intent to construct a new commercial/light industrial building for his hydroponic bean sprout business. The applicant submitted an existing site plan and a proposed site plan as an example of his intent. COMPREHENSIVE PLAN AND ZONING MAP CHANGE CRITERIA 1) The proposed amendment to the [Comprehensive Plan and] zoning map is consistent with the goals, objectives, and policies of the Comprehensive Plan. Comprehensive Plan policies discuss having identifiable boundaries for residential districts. Access and orientation of lots has an impact on the quality of the residential environment. Most single-family home owners prefer to see the same use across the street from them as evidenced by City policy of "identifiable neighborhood boundaries." The Site's existing orientation is to S. 134th Place, which is a commercial local access street, rather than to 48th Avenue S., which is a residential local access street. The existing structure, a home, sits at an elevation that is significantly below 48th Avenue S. which would make access via 48th Avenue more difficult, expensive, and potentially more impactful to Southgate stream than access via 134th Place. Thus, because access via S. 134th Place is preferred, including this Site in the C/LI district would be a logical boundary. In addition, the Comprehensive Plan's natural environment policies would support the redevelopment of the Site and the restoration of the buffer for the Southgate stream. A C/LI designation would potentially encourage the redevelopment of the Site. The Flower Power application for a map change is supported by the following Comprehensive Plan policies: The Residential Neighborhoods Element goal: A land use pattern that encourages a strong sense of community by grouping compatible and mutually supportive uses and separating incompatible uses. (G'oal7.1) The policies of that Element then speak about recognizable boundaries: Maintain a comprehensive land use map that supports the preservation and enhancement of single family and stable multi family neighborhoods; eliminates incompatible land uses; and clearly establishes applicable development requirements through recognizable boundaries. (Policy 7.1.1) Page 3 of 5 21 Exhibit A The C/LI zoned lot along the Site's north edge, 4625 S. 134th Place, is improved with an older house, but the lot is being used for parking for Holaday Park, which is the business located across S. 134th Place street (and in a C/LI district,) blurring the boundaries for these distinct zoning districts. The Natural Environment Element has the following goal: Watercourses and their buffers, .... are protected from encroachment and degradation and improved through mitigation, enhancement, and restoration projects. (Goal 4.6) It is difficult to see the development on the Site because the vegetation covers the site and stream; however, the existing structure was constructed over 7 decades ago in the stream buffer prior to enactment of the City's environmental regulations. A relevant Economic Development Element policy is: Promote and preserve economic use of industrial lands outside the MIC through appropriate buffering requirements and use restrictions. (Economic Development Policy 2.1.16) The applicant also lists an Economic Development Policy related to promoting and supporting business formation, expansion and the importance of the City's entrepreneurs and small busnesses in creating jobs. The applicant references several policies in the Community Image and Identity Element related to local food production and urban agriculture. 2) The proposed amendment to the Zoning Map is consistent with the scope and purpose of this title (the Zoning Code) and the description and purpose of the zone classification applied for. The purpose of the Commercial/Light Industrial (C/LI) designation and zone are, "...to provide for areas characterized by a mix of commercial, office, or Tight industrial uses. The standards are intended to promote viable and attractive commercial and industrial areas." (TMC 18.30.010) The Site is similar in character to the adjacent C/LI properties to the north in that it has frontage along S. 134th Place, has Southgate stream along its street frontage, has frequent truck traffic along it's frontage, and is similar in topography. The applicant discusses developing a commercial/light industrial business that would be consistent with the proposed Zone and the Site contains the characteristics of similar C/LI properties. The proposed C/LI zoning would allow the applicant to relocate his existing business, which is a hydroponic bean sprout grow operation, to the City of Tukwila from the City of Kent. His business is currently housed in a warehouse in Kent that is being displaced due to a Green River Levee project. The C/LI zone allows commercial greenhouses with no size limit whereas in LDR, greenhouses are allowed up to 1,000 square feet.) In contrast, the purpose of the Low Density Residential (LDR) district is "... to provide low -density family residential areas together with a full range of urban infrastructure services in order to maintain stable residential neighborhoods, and to prevent intrusions by incompatible land uses." (TMC 18.10.010) Except for the Site, the zoning designation of all properties fronting along S. 134th Place are C/LI. Page 4 of 5 22 Exhibit A The Site is rectangular with the narrow portion of the lot is along 48th Avenue S and the long side of the lot is along 134th Place. The Zoning Code stipulates that lot frontage shall be "considered the narrowest part of the lot that abuts a street." Because the Site is a corner lot and because there is a significant grade difference between 48th Avenue S. and the Site, access to the Site and overall orientation of the property is currently from S. 134th Place. 3) There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the Zoning [and Comprehensive Plan] Map. In 2007, a Type 2 Special Permission for a buffer reduction was granted to the property owner of 4501 S. 134th Place. Sound Transit acquired and in 2009 consolidated 11 residentially zoned parcels across 48th Avenue S and diagonally across the street from the Site. There was a Comprehensive Plan and Zoning map change in 2010 when 4300 S. 133rd S. was rezoned from C/LI to Medium Density Residential. Southgate Stream traverses this site and is located two blocks northwest of the Site. There have been no other zoning changes in this area since 1995, when the current zoning was instituted. New homes and short platting are occurring to the south and west of the Site in the LDR district. The initial zoning districts created and mapped for this area were not based upon an in-depth analysis of site specific conditions. Greater scrutiny of the site and neighborhood characteristics indicate that moving the C/LI boundary to 48th Avenue S., with conditions, meets the purpose of the C/LI zone. 4) The proposed amendment to the [Comprehensive Plan and] Zoning Map wall be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhoods, nor be injurious to other properties in the vicinity in which the subject property is located. The request would extend the boundary line for the C/LI district to 48th Avenue S. A comparison of standards between the LDR and C/LI zones shows that the standards are larger for uses in the C/LI than for single family homes in LDR. Also, the standards for building in C/LI increase when the site is within 50 feet of LDR, which would be the case for the Site. Standards in the C/LI zone are in place to minimize impact and any nuisance to adjacent residential properties. No on -site hazardous substance processing, handling, or storage is allowed unless clearly incidental to the permitted use and is subject to state siting criteria. Performance standards are in effect in the C/LI for air quality, noise and SEPA compliance and environmental regulations for restoring and protecting environmentally sensitive resources. The proposed change would set a more logical boundary and not negatively impact the residential environment of 48th Avenue 5. if access is limited to S. 134th Place. Compliance with the applicable C/LI and nonconforming standards will ensure the proposed use of the Site will not adversely affect or injure other properties in the vicinity.

PURPOSE STATEMENT: To provide safe and efficient movement of people and goods to, from, within, and through Tukwila. PURPOSE The Transportation Element establishes Tukwila's transportation goals and policies for the 20-year planning period. It provides direction for transportation decisions regarding annual plan updates, including: • The Six -Year Transportation Improvement Plan (TIP); The Six -Year Capital Improvement Program and Financial Planning Model (CIP/FPM); The biennial budget; and Infrastructure Design and Construction Standards. It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic Plan. It also provides guidance for development review and approval, land use and zoning decisions, and continuing transportation and maintenance programs. The Transportation Element establishes a basis for decision -making that is consistent with Washing- ton's Growth Management Act, King Countys Countywide Planning Policies, and the Puget Sound Regional Council's (PSRC) Transportation 2040. The specific requirements of each of these plans are fulfilled by the City of Tukwila Transportation Element Background Report (includinq a revised Travel Demand Memorandum dated December 30, 2016) of the Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and summarized herein. The Transportation Background Report, Walk and Roll Non -motorized Transportation Plan, Tukwila Transit Network Plan, Commute Trip Reduction (CTR) Program and Plan, Growth and Transportation Efficiency Center (GTEC) Plan, the annually -updated six -year Transportation Improvement Plan, six -year CIF,/ FPM, and the budget are all adopted by reference in the Tukwila Comprehensive Plan. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-2 26 ELEMENT 13 TRANSPORTATION ISSUES Tukwila's diverse transportation system includes freeways, highways, arterial streets, access streets, bus, light rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails and neighborhood footpaths. In addition, Sea-Tac International Airport and Boeing Field provide air transportation for general, commercial and business aviation. The Duwamish River provides water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail transportation within and through the city. Future Tukwila transportation system additions include Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained in the Background Report (Fehr& Peers, May2012). The major transportation issues facing Tukwila include the following: • Physical and geographic barriers that challenge connectivity throughout the City. Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City from each other, increasing emergency services response times and cost. Residents value quiet neighborhood streets that exist in an incomplete or disconnected street system. With relatively few "through"streets, many vehicles use the streets that do connect, burdening the adjacent properties and residents. The large volume of vehicles on through -streets also makes it more difficult to walk to destinations such as schools, libraries or shopping. • Limited funding to satisfy competing priorities. — Increasing connectivity is very costly given the need to acquire new rights -of -way, conducting engineering studies and design, and construction costs. — Criteria for grant funding are most often targeted to Tukwila's Urban Center or the Manufacturing/Industrial Center because these are the locations where significant employment and residential growth are planned and are supported by regional plans. — There are unmet needs in other areas of the City, including streets that do not meet City standards, and it is unlikely that the roads would be improved by new development in these already developed areas. • Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-3 27 ELEMENT 13 GOALS, POLICIES AND STRATEGIES TRANSPORTATION The Transportation Element supports the City's Land (ise Element. It demonstrates how the City will maintain and preserve the existing network as well as address deficiencies, while demonstrating how planned growth will be accommodated over the next 20 years per the Office of Financial Management (OFM) and PSRC forecasts. The household and job forecasts for Tukwila are for an additional 4i860 4,800 households and 27,67015,500 jobs by the year 2030 2031, with most of that occurring in the Southcenter, Tukwila International Boulevard and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs) based on the availability of vacant and redevelopable lands (Maps 13-1 and 13-2). Employment forecasts in the Transportation Element — and used for the Transportation Demand Model — that include 277670 15 500 additional jobs from 2010-2030 2031 are-nearly-doublethe ,500 additional -jobs -by 2031 ) were updated in a revised transportation model run in 2016. The original Transportation Demand Model run in 2010 was developed using employment forecast information available at the time. Since then, the employment forecast has-been was revised downward significantly due to the effects of the great recession on the regional economy. In addition, current forecasts are based to a greater degree on adopted King County Growth Targets for Tukwila. The City will revise the employment forecast and land use assumptions in the Transportation Element for consistency with land use -related elements and adopted growth targets during the next scheduled Transportation Demand Model update in 2016. GOAL 13.1 GENERAL Tukwila's transportation network provides for safe and efficient movement of people and goods to, from, within, and through Tukwila. GENERAL TRANSPORTATION POLICIES 13.1.1 Prioritize safety in an ongoing monitoring program. 13.1.2 Focus on transportation efficiency by maximizing the movement of people with streets that are designed to be safe for all transportation modes, accommodating existing land uses while designing for the future. 13.1.3 Balance travel efficiency, safety and quality -of -life in residential areas through creative roadway design.

The Countywide Planning Policies are a series of policies that address growth management in King County. The Countywide Planning Policies provide a county -wide vision and create a framework each jurisdiction can use when developing its own comprehensive plan. HOW DO THE COUNTYWIDE PLANNING POLICIES AFFECT TRANSPORTATION PLANNING IN TUKWILA? Because each city's comprehensive plan must be consistent with the overall County policy framework, Tukwila has incorporated some of the Countywide Planning Policies into this element. For example, the Countywide Planning Policies identify protection of the natural environment and transportation accessibility for non -drivers as regional priorities. The City has established policies 13.1.5 and 13.1.8 to address these needs. Other policies throughout this element will reference county -wide priorities and ensure thatTukwila's planning efforts are consistent with the overall transportation vision for King County. 13.1.4 Support, encourage and implement transportation programs and improvements that promote water quality and regional air quality. 13.1.5 Design and operate transportation facilities in a manner that is compatible with and integrated into the natural and built environments in which they are located. Incorporate features such as natural drainage, native plantings and local design themes that facilitate integration and compatibility. 13.1.6 Continue to coordinate with surrounding jurisdictions and with regional and State agencies to finance and develop a multi -modal transportation system that enhances regional mobility and reinforces the county- wide vision for managing growth. 13.1.7 Protect the transportation system (e.g. roadway, rail, transit, air and marine) against major disruptions by developing maintenance, prevention and recovery strategies and by coordinating disaster response plans. 13.1.8 Address the need for a range of mobility options including walking, biking, transit and driving in the development and management of local and regional transportation systems. 13.1.9 Support, encourage and implement programs and improvements that promote transit, foot and bicycle access to community amenities, stores and jobs. 13.1.10 Support car -share, bike -share and other alternatives to individual automobile ownershiip, to enhance sustainability. 13.1.11 Support electric vehicle charging stations and other alternative fuel sources, as available. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-7 33 ELEMENT 13 TRANSPORTATION STREET CLASSIFICATIONS For street design and operation purposes, engineers classify streets into four categories: principal arterials, minor arterials, collector arterials, and local access streets. These four categories group streets according to whether they primarily provide access to properties or are purely for mobility. The differences in function result in different street widths, number of curb cuts/driveways allowed, speed limit, traffic controls, and other similar design and operation features.

GOAL 13.2 STREET NETWORK The public street network has a hierarchy of street designs that serve pedestrian and vehicle safety, traffic movement, and adjacent land use. STREET NETWORK POLICIES 13.2.1 Develop a street network plan that augments the existing system of streets, breaks up super -blocks in non-residential areas, designs connecting through -streets in all areas, and provides functional separation of traffic through new streets. 13.2.2 Prioritize residential local access through -streets, minimizing cul-de-sacs. PAGE 13-8 34 ELEMENT 13 TRANSPORTATION 13.2.3 Create or require the creation of non -motorized connections in lieu of streets where local access through -streets are not feasible, such as on steep hillsides or where property owners resist streets. 13.2.4 Require street improvement projects and development improvements to be in accordance with the general Functional Street System Standards or subarea plans, and require an engineering study. 13.2.5 Require all new streets, street improvements, property developments and property improvements to provide sidewalks and other non -motorized infrastructure consistent with adopted standards and subarea plans. Property developments and improvements in commercial areas shall provide direct pedestrian access from sidewalks to buildings, as well as to, from and between parking areas. 13.2.6 Incorporate proportionately greater neighborhood -enhancing elements in collector, minor arterial, and principle arterial design. These elements include collector lanes, wider sidewalks, separated sidewalks, and curbline trees. 13.2.7 Design residential access streets to provide at least the minimum capacity for emergency access and for slow traffic. 13.2.8 Design collector arterials with a two -travel -lane, local access road design to encourage slow but steady speeds. 13.2.9 Design streets, including retrofit projects, to accommodate a range of motorized and non -motorized travel modes in order to reduce injuries and fatalities, tO provide access to services, and to encourage non -motorized travel. The design should include well-defined, safe and appealing spaces for pedestrians and bicyclists. 13.2.10 Evaluate street improvement projects for the inclusion of features that support the Complete Streets policy and the Walk and Roll Plan in order to encourage walking, bicycling and transit use. 13.2.11 Design intersections and sidewalks to promote pedestrian safety and foster walking as a viable mode of transportation. 13.2.12 Include roadside plantings whenever feasible for street and road improvement projects on slopes to help mitigate the land used for roadway and sidewalk improvements. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-9 35 ELEMENT 13 TRANSPORTATION WHAT IS TRANSPORTATIION CONCURRENCY? The Washington State Growth Management Act requires the City to ensure that transportation programs, projects and services needed to serve growth are regionally coordinated, and are in place either when new development occurs or within six years. This is done to make sure the City can provide the transportation improvements needed to maintain its adopted standards of service and so that conditions do not degrade with the addition of the new households and workers in the City. Implementation Strategies Implement sidewalk ordinance. Implement subdivision ordinance. Implement Street Network Plan. Emergency vehicle criteria in street design standards. Prioritize neighborhood quality design features when reducing street facilities (e.g., removal of one lane of parking before removal of sidewalk). . Traffic Calming Program. I Develop methods to incentivize and encourage coordinated development between adjacent commercial properties, including shared driveways and direct vehicular access !between parking lots. LEVEL OF SERVICE The projected growth numbers in Tukwila and surrounding areas were used in the Background Report for the Transportation Element of the Comprehensive Plan Update to anticipate traffic volumes and levels of service in 2030. The Level of Service (LOS) analysis is one of the ways the City plans and budgets for future transportation projects. The City balances the fiscal constraints of its financing plan for transportation programs and projects with planned growth and existing needs. To do this, Tukwila monitors LOS on arterial streets to examine the existing performance of the system and anticipated impacts of planned land use growth, to determine what adjustments will need to be made to maintain adopted LOS standards concurrent with new development. Properly applied and monitored, LOS standards for the transportation network ensure that mobility, vitality and quality of life for the city is maintained. For the 2030 planning horizon, significant new capacity will be required to accommodate future growth throughout the city, although the majority of the project capacity needs are in the Southcenter area. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-10 36 ELEMENT 13 TRANSPORTATION Traditionally, LOS has been used to evaluate vehicular flow with little regard to other forms of transportation such as pedestrians, bicycles and transit. Building upon Tukwila's Walk and Roll Plan, the Complete Streets standard and Transit Network Plan, the City is working to develop a Multi -Modal Level of Service (MMLOS) to help balance transportation goals across all modes of transportation. The City has identified Transit Priority Corridors as part of an analysis done for the Transit Network Plan, and will continue to work closely with transit providers to achieve goals and policies related to transit service, to serve existing needs and to accommodate future growth. AUTOMOBILE LOS In many ways, the existing performance of Tukwila's transportation system reflects how performance has historically been evaluated —with a strong bias towards auto travel. Automobile LOS is focused on setting an acceptable level of delay drivers can expect along a corridor or at a particular intersection. To see how the transportation system will function in the future, growth projections are incorporated into traffic models to determine future conditions along arterial streets and at intersections. Modeling results, along with a list of projects needed to maintain adopted LOS on arterial streets, are included in the Background Report. Tukwila's transportation system generally accommodates auto travel well, with just a handful of locations operating at a poor automobile LOS. NON -MOTORIZED LOS LOS for pedestrians and bicyclists is focused on measuring factors that impact the safety and comfort of pedestrians and bicycles rather than quantifying congestion and delay. In 2007 and 2008,Tukwila collected data on existing conditions for pedestrians and bicycle facilities on all arterial streets, using the 2010 Highway Capacity Manual's Multi -Modal Level of Service (2010 HCM MMLOS) methodology. The 2010 HCM MM LOS did not produce results that could be used in a similar fashion as the auto- mobile LOS, which categorizes minutes of delay into an A-F rating. The City needs to create or find a system for quantifying the conditions of pedestrian and bicycle facilities so that a goals -based ap- proach to prioritizing these projects is achieved. The City will continue to customize a non -motorized level of service measure to help achieve the City's vision of a more balanced mix of mobility options. TRANSIT LOS Transit service, both frequency and time -span of service, is an important aspect of a healthy transportation network. The City uses the Transit Capacity and Quality of Service Manual, published by the Transportation Research Board, as a methodology to measure level of service for transit. This recommended level of service methodology is included in the City's Transit Network Plan (Perteet 2004). The Plan identified service frequency needs for the City and facility improvements necessary for robust and effective transit service. Tables 13-1 and 13-2 illustrate LOS standards for transit service frequency and hours of service, respectively. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-11 37 ELEMENT 13 TRANSPORTATION Table 13-1 Service Frequency LOS: Urban Scheduled Transit Service Table 13-2 Hours of Service LOS LOS Headway (min) Vehicle/hour Comments A <10 >6 Passengers don't need schedule B 10-14 5-6 Frequent service, passengers consult schedules C 15-20 3-4 Maximum desirable time to wait if bus/train missed D 21-30 2 Service unattractive to choice riders E 31-60 1 Service available during hour F >60 <1 Service unattractive to all riders Source: Transit Capacity and Quality of Service Manual, 2nd Edition, 2003 LOS Hours per Day Comments A 19-24 Night or owl service provided B 17-18 Late evening service provided C 14-16 Early evening service provided D 12-13 Daytime service provided E 4-11 Peak hour service / limited midday service F 0-3 Very limited or no service Source: Transit Capacity and Quality of Servke Manual, 2nd Edition, 2003 King County Metro and Sound Transit provide transit service to Tukwila residents and businesses. At this time, the City is not the owner/operator of a transit service, therefore a minimum level of service standard cannot be enforced. However, Tukwila will encourage all transit providers to achieve and maintain a minimum LOS C and focus service within Tukwila's Transit Priority Corridors. Tukwila's goal is to have transit service every 15-20 minutes throughout most of the day on its Transit Priority Corridors, including early evening. The following is an assessment of existing transit service onTukwila'sTransit Priority Corridors: ® King County Metro identifies eight corridors in Tukwila on which it has set target service levels (see Table 13-3). Other bus routes not identified in Table 13-3 also currently serve Tukwila.

However, most corridors are not served with frequent service throughout the day with the exception of the Rapid Ride routes, including Rapid Ride A Line and the planned Rapid Ride F Line. D Link Light Rail, providing service between SeaTac Airport and Seattle, currently meets the City's LOS standard both in terms of frequency and time -span. (Sound Transit2013 Service Implementation Plan, p. 21) l There are currently nine northbound and nine southbound Sounder Trains providing service between Seattle and Lakewood, with a stop in Tukwila on the Sounder South Line. The Sounder South Line represents 90% of total Sounder ridership. Four new South Line round trips were implemented in September 2013, creating a schedule that includes 20-minute headways for the peak hour of service, which will bring the South Line into conformance with the City's LOS in terms of frequency during the peak hour, but will not meet the City's LOS in terms of time span. (Sound Transit2013 Service Implementation Pion, p. 29) GOAL 13.3 LEVEL OF SERVICE Traffic levels -of -service provide safe and efficient movement of pedestrians, bicycles, cars, buses and trucks, and incorporate evolving, sustainable land use and traffic patterns. LEVEL -OF -SERVICE POLICIES 13.3.1 In general, use varied Level of Service Standards according to differing levels of development, desired character of streets, and growth management objectives. 13.3.2 Use adopted LOS standards to guide City improvement and development approval decisions. 13.3.3 Maintain adopted LOS standards in planning, development and improvement decisions. 13.3.4 Provide capacity improvements or trip reduction measures so that the LOS standards are not exceeded. 13.3.5 Evaluate impacts to LOS when reviewing private development proposals, and require mitigation and/or reduce or delay project impacts, if necessary in order to maintain adopted LOS standards. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-13 39 ELEMENT 13 TRANSPORTATION 13.3.6 Prioritize transportation choices that provide capacity mitigation (i.e., transit use, carpooling/rideshare, pedestrian and bicycle facilities.) After considering these priority improvements, consider other street capacity improvements (Le., signal improvements, street widening) as a last resort. 13.3.7 Maintain a program to monitor congestion and evaluate the effectiveness of the LOS standards in providing a competitive business environment and adequate public safety response. AUTOMOBILE LEVEL OF SERVICE 13.3.8 Highways of Statewide significance (HSS), including Interstate 5 (1-5), Interstate 405 (1-405), and State Route 518 (SR-518), are exempt from concurrency requirements. 13.3.9 Use the following LOS standards to guide City improvement and development approval decisions: • The Southcenter area corridor average is not to exceed LOS E, except for the Strander Boulevard corridor and a portion of the Andover Park E corridors. Methods for computing the average LOS are described in the Background Report. • The Strander Boulevard corridor average is not to exceed LOS F with an average delay not to exceed 120 seconds. The Andover Park E corridor, between Tukwila Parkway and Strander Boulevard, is not to exceed LOS F with an average delay not to exceed 120 seconds. • All other non-residential arterial intersections are not to exceed LOS E. • The LOS of minor and collector arterials in predominantly residential areas is not to exceed LOS D for each specific arterial. • SR 181 (West Valley Highway) and SR 599, as State highways of regional significance, are subject to a Regional Level of Service Standard established by the Puget Sound Regional Council and WSDOT. Automobile level of service is not to exceed LOS E/Mitigated. • 1-5,1-405, SR 518 and SR 99, as highways of Statewide significance, are subject to a LOS standard established by WSDOT. Automobile level of service is not to exceed LOS D.

TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-15 41 ELEMENT 13 TRANSPORTATION TRANSIT The City of Tukwila strives to collaborate and cooperate with the region's transit providers in order to have convenient transit service to support and complement adjacent land uses. The goal of increasing overall transit ridership within the City of Tukwila drives the need for both service and capital improvements. Transit speed and reliability, improved passenger amenities, and access to transit service are all crucial for attracting and maintaining transit riders. King County Metro provides bus service throughout the City of Tukwila. Twelve different routes provide intra-Tukwila service and direct service to Burien, Kent, Auburn, Seattle, Renton and West Seattle. Existing Route 140 is planned to be upgraded to Rapid Ride bus rapid transit, with associated facilities, in 2014. At this time, Sound Transit does not serve any destinations in Tukwila with Regional Express Bus service. Sounder, the regional commuter rail service, has a stop in Tukwila at the Tukwila Station, as does Amtrak regional passenger rail service. Sound Transit Link Light Rail is located in Tukwila, with service from SeaTac Airport to downtown Seattle. Extensions of Link Light Rail are planned to the north, south, and east. To achieve the goal of increased transit frequency and time span of service toTukwila's activity centers and regional destinations, a multi -hub system and Transit Priority Corridor Classifications were developed, as shown on Map 13-3. Transit Priority Corridors are those corridors where transit service currently exists. Activity centers are tied together by the Transit Priority Corridors, and include the Tukwila International Boulevard Link Light Rail Station, the Tukwila Commuter Rail/Amtrak Station, an improved Southcenter Transit Center, and a new link connecting the Tukwila Commuter Rail/Amtrak Station to areas near Westfield Mall at Southcenter. Improved routes and frequency feed into this multi -hub concept. Transit Priority Corridor Classifications identify transit corridor types by function, ideal transit operational characteristics, optimal adjacent land uses, and supporting physical design features of the public infrastructure. The classification system is designed to be flexible and assist quality decision -making. An inventory of present transit routes is contained in the Background Report. Recommendations for service changes and infrastructure needs are contained in the Tukwila Transit Plan. King County Metro and Sound Transit control changes to routes.

TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-19 45 ELEMENT 13 TRANSPORTATION TRANSPORTATION DEMAN [P) MANAGE F ENT Transportation Demand Management (TDM) emphasizes the movement of people and goods, rather than vehicles, by providing transportation alternatives to driving. TDM benefits the community by maximizing the efficiency of existing infrastructure, and limiting the impacts of excessive traffic in neighborhoods by promoting transportation options such as carpooling, vanpooling, transit, walking, biking, teleworking and flexible work hours. Reducing vehicle trips limits air and water pollution and supports the City's commitment to reduce greenhouse gas emissions. Tukwila's TDM activities are directed at employers, workers, business owners, residents and visitors. Tukwila adopted a Commute Trip Reduction (CTR) Plan in 2008 that sets goals and implementation strategies for large employers to reduce drive -alone trips and vehicle miles traveled. Tukwila adopted a Growth and Transportation Efficiency Center (GTEC) Plan in 2008 to set the stage for focused TDM activities in Tukwila's urban center. The CTR Plan and GTEC Plan provide locally - adopted mode -split goals for Tukwila's Southcenter/Urban Center and the Manufacturing and Industrial Center (MIC). The City's six -year mode -split targets for the Urban Center are 65.7% drive -alone trips and 34.3% non -drive -alone trips, as defined in the City's GTEC Plan. Within the Urban Center, the City will also try to meet its GTEC goals with a targeted Vehicle Miles Travelled (VMT) rate of 13.05. In the MIC, mode -split goals are 70% drive -alone, consistent with the remainder of the city. TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-20 46 ELEMENT 13 TRANSPORTATION GOAL 13.5 TRANSPORTATION DEMAND MANAGEMENT Support transportation system improvements and programs which encourage transit use, high -occupancy vehicle trips and non -motorized transportation to reduce single -occupancy vehicle trips, vehicle miles traveled, traffic congestion, and greenhouse gas emissions. POLICIES 13.5.1 Provide Commute Trip Reduction Program services to Tukwila employers to reduce drive - alone trips, vehicle miles traveled, traffic congestion, and greenhouse gas emissions. 13.5.2 The City of Tukwila will set an example to other employers by a commitment to reducing drive -alone trips, vehicle miles traveled, and greenhouse gas emissions through implementation of CTR goals. 13.5.3 Work with King County Metro and Sound Transit to provide amenities for transit riders, encourage transit use, and enhance multi -modal connections to transit. 13.5.4 Establish mode -split goals for all significant employment centers which will vary according to development densities, access to transportation service, and levels of congestion. 13.5.5 Continue to encourage the use of rideshare, transit, bicycle, and evolving technological transportation improvements. 13.5.6 Encourage transit -oriented uses, development patterns and pedestrian amenities in the vicinity of high -capacity transit stations. 13.5.7 Require that parking facilities developed in conjunction with transit facilities be adequately sized and managed to prevent spillover parking onto private property, public property, or public streets.

TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-21 47 ELEMENT 13 TRANSPORTATION NON -MOT. R ZE ANSPO TATa1M Tukwila adopted its first non -motorized transportation plan — the Walk and Roll Plan — in 2009, as well as a Complete Streets policy. This policy requires all new City transportation improvement projects to provide appropriate accommodation for pedestrians, bicyclists, transit riders and persons of all abilities, while promoting safe operation for all users. The Walk and Roll Plan includes an inventory of existing non -motorized facilities, including bike lanes, trails, sidewalks and pedestrian footpaths (see Map 13-4). The Plan also identifies projects to guide City implementation of a safe and complete non -motorized network. These projects are made up of (1) a list of missing sidewalk segments and a method of prioritizing which missing segments should be constructed first, (2) trail projects to expand the existing system of non -motorized neighborhood connections, and (3) a backbone network of Bicycle Friendly Routes — existing and planned on -street facilities and trail projects that represent a bicycle network connected to local and regional destina- tions, as well as existing and planned bicycle -friendly routes in adjacent jurisdictions (see Map 13-5). The Walk and Roll Plan commits the City to promoting programs that support and encourage biking, walking, commute trip reduction activities, and the City's annual participation in the regional bicycle and pedestrian count. GOAL 13.6 NON -MOTORIZED TRANSPORTATION Tukwila's non -motorized transportation network is safe and comfortable, provides local and regional connections to neighborhoods and activity centers, and makes cycling and walking viable and enjoyable forms of transportation and recreation. POLICIES 13.6.1 Consider and provide for all users of the roadway, including pedestrians and bicyclists, as appropriate, when new streets and street improvements are made. 13.6.2 Allocate funds to the Residential Street Fund in order to build sidewalks on residential local access streets. 13.6.3 Include pedestrian and bicycle improvements in street improvement projects, as appropriate. The prioritized list of missing sidewalk linkages and the Bicycle Friendly Routes map adopted with the Walk and Roll Non -motorized Transportation Plan is the priority network to connect schools, employment centers, parks, shopping and other local and regional destinations.

TUKWILA COMPREHENSIVE PLAN - 2015 PAGE 13-26 52 ELEMENT 13 TRANSPORTATION FREBG.T: T, RAIL, ATE 1 DOT _tS' 'TTOO Tukwila's Urban Center and Manufacturing and Industrial Center (MIC) include retail, commercial and industrial businesses which serve the region. Railroad tracks owned by the Burlington Northern Santa Fe (BNSF) and Union Pacific (UP) railroads run north/south through Tukwila. These rail networks carry international and domestic cargo to inland markets, and serve the Port of Seattle to the north and the Port of Tacoma to the south. Industrial railroad spurs, operated and controlled by the railroad companies and private property owners, are located in the Southcenter and MIC area. BNSF has a multi -modal storage yard in the Manufacturing and Industrial Center in northern Tukwila. Both Amtrak and Sound Transit's Sounder Commuter Rail use the BNSF tracks. Given Tukwila's location at the crossroads of two major interstate highways, and the prevalence of manufacturing, warehousing and commercial activities in the City, many streets experience high truck volumes. The streets with the highest truck traffic are West Valley Highway south of Strander Boulevard, Interurban Avenue South north of SR 599, and East Marginal Way South north of Boeing Access Road. The portion of the Duwamish River in Tukwila north of the Turning Basin is located within the City's Manufacturing and Industrial Center and is accessible to shipping activity. The river remains inaccessible to shipping activity south of the Turning Basin, where it can be accessed by small water craft, kayaks and canoes only. King County International Airport, also known as Boeing Field, is located in northern Tukwila at the City's border with Seattle, and is one of the busiest primary non -hub airports in the nation. The airport serves small commercial passenger airlines, cargo carriers, private aircraft owners, helicopters, corporate jets, and military and other aircraft. It is also home to approximately 150 tenant businesses, including the Boeing Company operations. The Museum of Flight is also located there and attracts a large number of visitors to the area. Sea-Tac Airport, the State's largest airport, is located within a mile ofTukvvila city limits.

The EIS was previously issued on October 9,1995 (File #L92-0053). STAFF: Robin Tischmak, City Engineer ATTACHMENTS: A. Fehr & Peers Memo B. Transportation Element Revisions Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov 41 FINDINGS BACKGROUND In 2010 the Public Works Department began updating the Transportation element of Tukwila's Comprehensive Plan as part of a phased review and update mandated by the State. The update included a traffic modeling effort based on projected household and employment growth throughout the City until the year 2030. These growth numbers were determined at a regional level and provided to each jurisdiction for use in long range planning efforts. AfterTukwila's updated element was adopted the Puget Sound Regional Council (PSRC) developed revised growth projections that reflected the reduced economic activity due to the 2008-2009 recession. These numbers showed a small reduction in projected household growth and a significant reduction in projected employment growth (nearly 50%). The other elements of the Tukwila Comprehensive Plan were updated in later phases using the revised PSRC numbers and a 2031 time horizon, leading to an internal discrepancy in the Plan. Tukwila received conditional approval for its Plan update in 2016 with the requirement that the discrepancy be addressed through adoption of an updated Transportation Element by December of 2017. Attachment B contains the proposed revisions to meet the PSRC requirements for certification. The Transportation and Infrastructure Committee was briefed on August 14, 2017 and they forwarded the issue to the Planning Commission for review. COMPREHENSIVE PLAN REVIEW CRITERIA Planning Commission review is required for Comprehensive Plan and Zoning Code amendments. The Planning Commission may recommend approval, recommend approval with conditions or recommend denial of the amendment based on a clear compliance with the criteria that follow. The Planning Commission's recommendation will be forwarded to the City Council, which will make the final decision. (TMC 18.80 and 18.84) 1) Describe how the issue is addressed in the Comprehensive Plan. If the issue is not adequately addressed, is there a need for it? The proposed update is a technical correction to the growth projections used in the Transportation Element needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The lower employment projections resulted in estimates of lower vehicle miles traveled and no lowering of levels of service (LOS). As a result of this change no goals, policies or capital improvement project changes are proposed as part of this action. The changes involve text edits to the narrative and updated maps. 2) If the issue is not adequately addressed in the Comprehensive Plan, is there a need for the proposed change? Under the original, higher projections we received from PSRC Tukwila had planned to accommodate higher household and employment growth than currently projected. Much of this growth was anticipated in the Tukwila South area, which remains largely undeveloped. The timeline for development is unclear, though at least some is likely to occur within the 2031 time horizon of the current Comprehensive Plan. Page 2 of 3 42 3) Is the proposed change the best means for meeting the identified pulbtic need? What other options are there for meeting the identified public need? As part of the conditional certification process the City of Tukwila agreed to the following conditions: 1. Tukwila City Council adoption of a plan of work that addresses the condition identified in the certification report by May 31, 2016. Adopted 5/2/2016 2. Submission of a draft amended comprehensive plan and supporting documents that address the condition to PSRC for review and comment in advance of adoption. Sent August 14, 2017, PSRC has confirmed that these changes are adequate to meet the condition. 3. Once the condition is adequately addressed, submission of adopted amended comprehensive plan and supporting documents by December 31, 2017 for review and certification by PSRC. 4) Will the proposed change result in a net benefit to the community? Gaining full certification for Tukwila's Comprehensive Plan will maintain our eligibility for PSRC and Regional Transportation Improvement Program funding. CONCLUSIONS In reviewing Comprehensive Plan criteria, staff concludes that the proposed update is a technical correction to the growth projections used in the Transportation Element needed to bring internal consistency to the Comprehensive Plan and meet PSRC conditions for certification. The projected traffic levels are lower under the revised employment levels and therefore no impacts are expected that were not already addressed under the original Element. As a result of this change no goals, policies or capita( improvement project changes are needed or proposed as part of this action. RECOMMENDATION Staff recommends that the Planning Commission forward the proposed edits and updates to the Transportation Element shown in Attachment B to the City Council with a recommendation of adoption.

It provides direction for transportation decisions regarding annual plan updates, including. ✓ The Six -Year Transportation Improvement Plan (TIP); ✓ The Six -Year Capital Improvement Program and Financial Planning Model (CIP/FPM); ✓ The biennial budget; and ✓ Infrastructure Design and Construction Standards. It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic Plan. It also provides guidance for development review and approval, land use and - zoning decisions, and continuing transportation and maintenance programs. The Transportation Element establishes a basis for decision -making that is consistent with Washington's Growth Management Act, King County's Countywide Planning Policies, and the Puget Sound Regional Council's (PSRC) Transportation 2o4o. The specific requirements of each of these plans are fulfilled by the City of Tukwila Transportation Element Background Report((including a revised Travel Demand Memorandum dated December 3o, 2o1.6) of the Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and summarized herein. The Transportation Background Report, Walk and Roll Non - motorized Transportation Plan, Tukwila Transit Network Plan, Commute Trip Reduction (CTR) Program and Plan Growth and Transportation Efficiency_Center (GTEC) Plan, the annually - updated six -year Transportation Improvement Plan, six -year CIP/FPM, and the budget are all adopted by reference in the Tukwila Comprehensive Plan. ISSUES Tukwila's diverse transportation system includes freeways, highways, arterial streets, access streets, bus, light rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails and neighborhood footpaths. In addition, Sea-Tac International Airport and Boeing Field provide air transportation for general, commercial and business aviation. The Duwamish River provides water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail transportation within and through the city. Future Tukwila transportation system additions include Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained in the Background Report (Fehr& Peers, Mayzo12). The major transportation issues facing Tukwila include the following: u Physical and geographic barriers that challenge connectivity throughout the City. Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City from each other, increasing emergency services response times and cost. Residents value quiet neighborhood streets that exist in an incomplete or disconnected street system. With relatively few "through" streets, many vehicles use the streets that do Commented [RT11: RRT 1 connect, burdening the adjacent properties and residents. The large volume of vehicles on through -streets also makes it more difficult to walk to destinations such as schools, libraries or shopping. u Limited funding to satisfy competing priorities. — Increasing connectivity is very costly given the need to acquire new rights -of -way, conducting engineering studies and design, and construction costs. — Criteria for grant funding are most often targeted to Tukwila's Urban Center or the Manufacturing/Industrial Center because these are the locations where significant employment and residential growth are planned and are supported by regional plans. — There are unmet needs in other areas of the City, including streets that do not meet City standards, and it is unlikely that the roads would be improved by new development in these already developed areas. u Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. GOALS, POLICIES AND STRATEGIES The Transportation Element supports the City's Land Use Element. It demonstrates how the City will maintain and preserve the existing network as well as address deficiencies, while demonstrating how planned growth will be accommodated over the next zo years per the Office of Financial Management (OFM) and PSRC forecasts. The household and job forecasts for Tukwila are for an additional14,86o4,80o households and }e15.coo jobs by theyearfzo3ozolzl with most of that occurring in the Southcenter, Tukwila International Boulevard and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs) based on the availability of vacant and redevelopable lands (Maps 13-1 and 13-2). Employment forecasts in the Transportation Element — and used for the Transportation Demand Model —that include;z7,67016,50o additionaljobs from 20104e3e-2o31 arc nearly double the growth that currcnt growth targets and forccasts represent (i.c.,15,50o additional jobs by zo31)were updated in a revised transportation model run in zoldl. The original Transportation Demand Model 'run in zolo [was developed using employment forecast information available at the time. Since then, the employment forecast has-been.was{revised downward significantly due to the effects of the great recession on the regional economy.

The Washington State Growth Management Act requires the City to ensure that transportation programs, projects and services needed to serve growth are regionally coordinated, and are in place either when new development occurs or within six years. This is done to make sure the City can provide the transportation improvements needed to maintain its adopted standards of service and so that conditions do not degrade with the addition of the new households and workers in the City. TUKWILA COMPREHENSIVE PLAN - 2015 Implementation Strategies r i Implement sidewalk ordinance. L`I Implement subdivision ordinance. Implement Street Network Plan. r. Emergency vehicle criteria in street design standards. Prioritize neighborhood quality design features when reducing street facilities (e.g., removal of one lane of parking before removal of sidewalk). Traffic Calming Program. Develop methods to incentivize and encourage coordinated development between adjacent commercial properties, including shared driveways and direct vehicular access between parking Tots. LEVEL OF SERVICE The projected growth numbers inTukvvila and surrounding areas were used in the Background Report for the Transportation Element of the Comprehensive Plan Update to anticipate traffic volumes and levels of service in delete - 2030 (and add 2031) The Level of Service (LOS) analysis is one of the ways the City plans and budgets for future transportation projects. The City balances the fiscal constraints of its financing plan for transportation programs and projects with planned growth and existing needs. To do this, Tukwila monitors LOS on arterial streets to examine the existing performance of the system and anticipated impacts of planned land use growth, to determine what adjustments will need to be made to maintain adopted LOS standards concurrent with new development. Properly applied and monitored, LOS standards for the transportation network ensure that mobility, vitality and quality of life for the city is maintained. For the delete - 2030 (and add - 2031) planning horizon, significant new capacity will be required to accommodate future growth throughout the city, although the majority of the project capacity needs are in the Southcenter area.

PSRC's review noted that the employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. The discrepancy in the land use growth allocation occurred because the City of Tukwila updated the Transportation Element between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008-2009 recession and resulting slowdown in the real estate market. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. In response to this comment, the City hired Fehr & Peers to reallocate land use growth to be consistent with current PSRC Land Use Vision and to re -run the City's travel demand model. Key findings include: • The 2031 forecasted traffic volumes are not expected to grow as much within the City compared to the previous analysis (VMT is lower by three percent). • Most of the forecasted traffic volume decreases are in the Tukwila South area, where growth is not as rapid as was previously anticipated and where most of the employment growth was reduced. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com 45 L. Benjamin July 28, 2017 Page 2 of 2 • No changes are recommended to the proposed transportation capital improvement projects. Most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks. The large roadway projects to facilitate growth in Tukwila South were completed by the developer in the 2010-2012 timeframe. Attached is a memo detailing the analysis to reallocate land use growth to be consistent with current forecasts, as well as two maps that illustrate the distribution of household and employment growth by 2031 within the City.

Sincerely, FEHR & PEERS Cvw.,A/ Carmen Kwan Transportation Engineer/Planner 5E16-0498 Attachment: • Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments Memo 46 FEHRk PEERS MEMORANDUM Date: December 30, 2016 To: Robin Tischmak and Bob Giberson, City of Tukwila From: Carmen Kwan and Chris Breiland, Fehr & Peers Subject: Tukwila 2031 Land Use Revision — Travel Demand Modeling Response to PSRC Comments SE16-0498 The Puget Sound Regional Council (PSRC) reviewed the City of Tukwila's draft Comprehensive Plan Elements in 2013 and identified that the land use growth forecast by 2031 in the Transportation Element was higher than current PSRC growth assumptions. In response to this comment, the forecast land use growth was revised to be consistent with PSRC assumptions and the City's travel demand model was re -run. This document details the analysis process and summarizes the new model results. The transportation capital improvement projects previously proposed were also reviewed to identify if any changes in the project list would be necessary based on the new growth forecasts. BACKGROUND The City of Tukwila updated the Transportation Element of the Comprehensive Plan between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008- 2009 recession and resulting slowdown in the real estate market nationwide. In general, the earlier PSRC land use forecasts predicted more growth by 2031 than the current (2016) land use forecasts. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. The rest of this memorandum describes the method used to align the Transportation Element growth forecasts with the rest of the Comprehensive Plan. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com 47 City of Tukwila December 30, 2016 Page2of5 ANALYSIS METHODOLOGY The previous analysis completed for the Transportation Element assumed a growth of 27,665jobs and 4,905 households by 2031. PSRC's review noted that this employment growth for the City of Tukwila is almost double the current forecast of 15,500job growth between 2010 and 2031. PSRC also forecasts a slightly lower number of households in the city by 2031 (4,800 new households). Land Use Revision In response to these comments, the 2031 land use assumptions were revised and the City's travel demand model was re -run to evaluate how traffic forecasts would change from the previous 2031 analysis (prepared with the higher growth forecasts). Key assumptions are listed below: • Land use forecasts were revised to match the Land Use Vision (LUV.1) Dataset, the most recent land use forecasts released by the PSRC in September 2015. • Land use growth assumptions in the Southcenter Subarea of Tukwila remained relatively consistent with the Southcenter Regional Growth Center EIS analysis prepared in 2014. Growth was adjusted elsewhere in the City based on the LUV.1 Dataset. A summary of the assumed land use growth is presented in Table 1. The revised 2031 forecasts show that the land use assumptions are consistent with PSRC growth assumptions of 4,800 households and 15,500jobs between 2010 and 2031. The revised 2031 land use has a decrease of 105 households and 14,140 jobs compared to the previous analysis. Land use growth assumptions by TAZ are in Attachment A. TABLE 1.

An example travel demand model difference plot of the change in PM peak hour traffic volume per travel lane is shown in Figure 1. The green bars show a decrease in vehicle traffic and the red bars show an increase in vehicle traffic compared to the previous 2031 analysis. FIGURE 1. 2031TRAVEL DEMAND MODEL DIFFERENCE PLOT Source: Fehr & Peers, 2016. 49 City of Tukwila December 30, 2016 Page 4 of 5 While there is some model "noise" in the difference plot results where some routes have minor increase or decrease in vehicle volumes compared to before, the overall observations from the new travel model runs are summarized below. • The 2031 forecasted traffic volumes are not expected to grow as much within the City of Tukwila compared to the previous analysis. The slightly lower vehicle traffic growth is reasonable based on the reduction of approximately 14,100 jobs and 100 households throughout the City by 2031 compared to the previous analysis. The new 2031 model run's slightly lower traffic growth is minor as there is only a three percent decrease in vehicle - miles -travelled (VMT) on City streets during the PM period compared to the previous analysis (excluding freeways). • Most of the forecasted traffic volume decreases are south of S 180th Street. This is expected as the growth near Southcenter Regional Growth Center did not change much from the earlier analysis, and most of the employment reduction was in the Tukwila South area, where growth is not as rapid as was anticipated in the earlier forecasts. Overall, City staff felt this area had the least amount of momentum for growth compared to the rest of the City. • No changes are recommended to the proposed transportation capital improvement projects. A review of the previously recommended projects was completed based on the new model run results. In general, all the projects identified in the Transportation Element are recommended to remain because: o Most of the street extension projects were recommended to reduce block size and improve mobility for all modes. These projects would improve street grid connectivity, improve the walkability by breaking up large blocks, and potentially improve emergency response times. While there is a minor decrease in vehicle volumes in the new model run compared to the previous results, projects are recommended to remain to help the City achieve the desired urban form and street network connectivity pattern. o Intersection improvements at various intersections such as adding turn pockets are still recommended as the model shows that turning volumes that triggered the additional turn lanes will not decrease enough to eliminate the need for the additional lanes. o Many projects were identified to enhance pedestrian and/or bicycle facilities. While growth is slightly lower with the new land use forecasts, the need for a 50 City of Tukwila December 30, 2016 Page 5 of 5 comprehensive and connective pedestrian and bicycle network is not altered by the revised land use forecasts. CONCLUSION A new travel model run was completed with revised 2031 land use growth reallocated to be consistent with PSRC's vision of 15,500 new jobs and 4,800 new households between 2010 and 2031 in Tukwila. Based on the results of the new travel model run, no changes to the Transportation Element project list are recommended. While the traffic growth by 2031 is not expected to be as high as the previous analysis (VMT is lower by three percent), most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks.

It provides direction for transportation decisions regarding annual plan updates, including: ✓ The Six -Year Transportation Improvement Plan (TIP); ✓ The Six -Year Capital Improvement Program and Financial Planning Model (CIP/FPM); ✓ The biennial budget; and ✓ Infrastructure Design and Construction Standards. It is key in supporting community livability and economic vitality, as prioritized in Tukwila's Strategic Plan. It also provides guidance for development review and approval, land use and zoning decisions, and continuing transportation and maintenance programs. The Transportation Element establishes a basis for decision -making that is consistent with Washington's Growth Management Act, King County's Countywide Planning Policies, and the Puget Sound Regional Council's (PSRC) Transportation 2040. The specific requirements of each of these plans are fulfilled by the City of Tukwila Transportation Element Background Report (including a revised Travel Demand Memorandum dated December p 2oibof the Comprehensive Plan Update (hereafter referred to in this element as the Background Report), and summarized herein. The Transportation Background Report, Walk and Roll Non -motorized Transportation Plan, Tukwila Transit Network Plan Commute Trip Reduction (CTR) Program and Plan, Growth and Transportation Efficiency,Center (G.TEC) Plan, the annually -updated six -year Transportation Improvement Plan, six - year CIP/FPM, and the budget are all adopted by reference in the Tukwila Comprehensive Plan. ISSUES Tukwila's diverse transportation system includes freeways, highways, arterial streets, access streets, bus, light rail, commuter rail transit service, Amtrak passenger rail service, sidewalks, trails and neighborhood footpaths. In addition, Sea-Tac International Airport and Boeing Field provide air transportation for general, commercial and business aviation. The Duwamish River provides water access to Elliott Bay and beyond. The City's road and rail network enables freight and rail transportation within and through the city. Future Tukwila transportation system additions include Bus Rapid Transit. A detailed inventory of the existing transportation system in Tukwila is contained in the Background Report (Fehr& Peers, May 2o12). The major transportation issues facing Tukwila include the following: u Physical and geographic barriers that challenge connectivity throughout the City. Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City from each other, increasing emergency services response times and cost. Residents value quiet neighborhood streets that exist in an incomplete or disconnected street system. With relatively few "through" streets, many vehicles use the streets that do connect, burdening the adjacent properties and residents. The large volume of vehicles on through -streets also makes it more difficult to walk to destinations such as schools, libraries or shopping. u Limited funding to satisfy competing priorities. 58 — Increasing connectivity is very costly given the need to acquire new rights -of -way, conducting engineering studies and design, and construction costs. — Criteria for grant funding are most often targeted to Tukwila's Urban Center or the IManufacturing/industrial Center because these are the locations where significant employment and residential growth are planned and are supported by regional plans. — There are unmet needs in other areas of the City, including streets that do not meet City standards, and it is unlikely that the roads would be improved by new development in these already developed areas. u Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. GOALS, POLICIES AND STRATEGIES The Transportation Element supports the City's Land Use Element. It demonstrates, how the City will maintain and preserve the existing network as well as address deficiencies, while demonstrating how planned growth will be accommodated over the next 20 years per the Office of Financial Management (OFM) and PSRC forecasts. The household and job forecasts for Tukwila are for an additional e4 800 households and -=7;6703.5,Soo jobs by the year =2a wl with most of that occurring in the Southcenter, Tukwila International Boulevard and Tukwila South mixed -use commercial areas. To plan for land use and transportation changes associated with this growth, these households and jobs are assigned to Traffic Analysis Zones (TAZs) based on the availability of vacant and redevelopable lands (Maps 23-1 and 23-2).

The Washington State Growth Management Act requires the City to ensure that transportation programs, projects and services needed to serve growth are regionally coordinated, and are in place either when new development occurs or within six years. This is done to make sure the City can provide the transportation improvements needed to maintain its adopted standards of service and so that conditions do not degrade with the addition of the new households and workers in the City. TUKWILA COMPREHENSIVE PLAN - 2015 Implementation Strategies Implement sidewalk ordinance. Implement subdivision ordinance. Implement Street Network Plan. Emergency vehicle criteria in street design standards. Prioritize neighborhood quality design features when reducing street facilities (e.g., removal of one lane of parking before removal of sidewalk). Traffic Calming Program. Develop methods to incentivize and encourage coordinated development between adjacent commercial properties, including shared driveways and direct vehicular access between parking lots. LEVEL OF CE The projected growth numbers in Tukwila and surrounding areas were used in the Background Report for the Transportation Element of the Comprehensive Plan Update to anticipate traffic volumes and levels of service in delete - 2030 (and add 2031) The Level of Service (LOS) analysis is one of the ways the City plans and budgets for future transportation projects. The City balances the fiscal constraints of its financing plan for transportation programs and projects with planned growth and existing needs. To do this, Tukwila monitors LOS on arterial streets to examine the existing performance of the system and anticipated impacts of planned land use growth, to determine what adjustments will need to be made to maintain adopted LOS standards concurrent with new development. Properly applied and monitored, LOS standards for the transportation network ensure that mobility, vitality and quality of life for the city is maintained. For the delete - 2030 (and add - 2031) planning horizon, significant new capacity will be required to accommodate future growth throughout the city, although the majority of the project capacity needs are in the Southcenter area.

City of Tukwila Allan Ekberg, Mayor Public Works Department - Bob Giberson, Director INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Commije FROM: Bob Giberson, Public Works Directori'�i BY: Robin Tischmak, City Engineer CC: Mayor Ekberg DATE: August 11, 2017 SUBJECT: Tukwila Comprehensive Plan Transportation Element Update ISSUE Approve updates to the Transportation Element of Tukwila's Comprehensive Plan. BACKGROUND In 2010 the Public Works Department initiated an effort to update the Transportation Element (Chapter 13) of the Tukwila Comprehensive Plan. The effort included a traffic modeling effort that included projected household and employment growth throughout the City through the year 2030. This effort was in conjunction with an overall update to the Comprehensive Plan. Subsequently, the Puget Sound Regional Council (PSRC) provided updated growth data that reflected the 2008-2009 recession. The updated growth data showed a small reduction for projected household growth and a significant reduction in projected employment (nearly 50%). DISCUSSION The review by PSRC identified discrepancies within Tukwila's Plan that indicated conflicting growth information between different chapters of the plan as well as a differing projected end year. The modeling effort projected through year 2030 while the remainder of the plan projected through year 2031. PSRC requested that the City run a revised model update that reflected the updated growth data as well as the 2031 horizon year. Attached are the proposed revisions for consideration and approval. FINANCIAL IMPACT There is no financial impact. RECOMMENDATION Council is being asked to accept the attached Transportation Element revisions and forward this item for discussion at the August 28, 2017 Committee of the Whole Meeting and subsequent September 5, 2017 Regular Council Meeting.

PSRC's review noted that the employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. The discrepancy in the land use growth allocation occurred because the City of Tukwila updated the Transportation Element between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008-2009 recession and resulting slowdown in the real estate market. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. In response to this comment, the City hired Fehr & Peers to reallocate land use growth to be consistent with current PSRC Land Use Vision and to re -run the City's travel demand model. Key findings include: • The 2031 forecasted traffic volumes are not expected to grow as much within the City compared to the previous analysis (VMT is lower by three percent). • Most of the forecasted traffic volume decreases are in the Tukwila South area, where growth is not as rapid as was previously anticipated and where most of the employment growth was reduced. 1001 4th Avenue Suite 4120 Seattle, WA 98154 I (206) 576-4220 Fax (206) 576-4225 www.fehrandpeers.com 34 L. Benjamin July 28, 2017 Page 2 of 2 • No changes are recommended to the proposed transportation capital improvement projects. Most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks. The large roadway projects to facilitate growth in Tukwila South were completed by the developer in the 2010-2012 timeframe. Attached is a memo detailing the analysis to reallocate land use growth to be consistent with current forecasts, as well as two maps that illustrate the distribution of household and employment growth by 2031 within the City.

The Washington State Growth Management Act requires the City to ensure that transportation programs, projects and services needed to serve growth are regionally coordinated, and are in place either when new development occurs or within six years.This is done to make sure the City can provide the transportation improvements needed to maintain its adopted standards of service and so that conditions do not degrade with the addition of the new households and workers in the City. Implementation Strategies i Implement sidewalk ordinance. Implement subdivision ordinance. Implement Street Network Plan. Emergency vehicle criteria in street design standards. Prioritize neighborhood quality design features when reducing street facilities (e.g., removal of one lane of parking before removal of sidewalk). Traffic Calming Program. Develop methods to incentivize and encourage coordinated development between adjacent commercial properties, including shared driveways and direct vehicular access between parking lots. LEVEL OF SERVICE The projected growth numbers in Tukwila and surrounding areas were used in the Background Report for the Transportation Element of the Comprehensive Plan Update to anticipate traffic volumes and levels of service in'deleter 2030" (and add 2031) The Level of Service (LOS) analysis is one of the ways the City plans and budgets for future transportation projects. The City balances the fiscal constraints of its financing plan for transportation programs and projects with planned growth and existing needs. To do this, Tukwila monitors LOS on arterial streets to examine the existing performance of the system and anticipated impacts of planned land use growth, to determine what adjustments will need to be made to maintain adopted LOS standards concurrent with new development. Properly applied and monitored, LOS standards for the transportation network ensure that mobility, vitality and quality of life for the city is maintained. For the delete 2030 (and add �2031) planning horizon, significant new capacity will be required to accommodate future growth throughout the city, although the majority of the project capacity TUKWILA COMPREHENSIVE PLAN - 2015 needs are in the Southcenter area.

In response to this comment, the forecast land use growth was revised to be consistent with PSRC assumptions and the City's travel demand model was re -run. This document details the analysis process and summarizes the new model results. The transportation capital improvement projects previously proposed were also reviewed to identify if any changes in the project list would be necessary based on the new growth forecasts. BACKGROUND The City of Tukwila updated the Transportation Element of the Comprehensive Plan between 2010 and 2012, in part because of a major planned development in the southern portion of the city that could potentially impact the long-term transportation needs for the City. At that time, the PSRC regional land use forecasts had not yet been adjusted to account for the magnitude of the 2008- 2009 recession and resulting slowdown in the real estate market nationwide. In general, the earlier PSRC land use forecasts predicted more growth by 2031 than the current (2016) land use forecasts. The other elements of the Tukwila Comprehensive Plan were updated during the 2013-2015 period and incorporated the more recent (lower) growth forecasts from the PSRC. The rest of this memorandum describes the method used to align the Transportation Element growth forecasts with the rest of the Comprehensive Plan. 1001 4th Avenue I Suite 4120 I Seattle, WA 98154 I (206) 576-4220 I Fax (206) 576-4225 www.fehrandpeers.com 45 City of Tukwila December 30, 2016 Page 2 of 5 ANALYSIS METHODOLOGY The previous analysis completed for the Transportation Element assumed a growth- of 27,665 jobs and 4,905 households by 2031. PSRC's review noted that this employment growth for the City of Tukwila is almost double the current forecast of 15,500 job growth between 2010 and 2031. PSRC also forecasts a slightly lower number of households in the city by 2031 (4,800 new households). Land Use Revision In response to these comments, the 2031 land use assumptions were revised and the City's travel demand model was re -run to evaluate how traffic forecasts would change from the previous 2031 analysis (prepared with the higher growth forecasts). Key assumptions are listed below: • Land use forecasts were revised to match the Land Use Vision (LUV.1) Dataset, the most recent land use forecasts released by the PSRC in September 2015. • Land use growth assumptions in the Southcenter Subarea of Tukwila remained relatively consistent with the Southcenter Regional Growth Center EIS analysis prepared in 2014. Growth was adjusted elsewhere in the City based on the LUV.1 Dataset. A summary of the assumed land use growth is presented in Table 1. The revised 2031 forecasts show that the land use assumptions are consistent with PSRC growth assumptions of 4,800 households and 15,500 jobs between 2010 and 2031. The revised 2031 land use has a decrease of 105 households and 14,140 jobs compared to the previous analysis. Land use growth assumptions by TAZ are in Attachment A. TABLE 1.

An example travel dernand model difference plot of the change in PM peak hour traffic volume per travel lane is shown in Figure 1. The green bars show a decrease in veh cle traffic and the red bars show an increase in vehicle traffic compared to the previous 2031 analysis. FIGURE 1. 2O31TRAVEL DEMAND MODEL DIFFERENCIE PLOT Source: Fehr & Peers, 2016. 47 City of Tukwila December 30, 2016 Page 4 of 5 While there is some model "noise" in the difference plot results where some routes have minor increase or decrease in vehicle volumes compared to before, the overall observations from the new travel model runs are summarized below. • The 2031 forecasted traffic volumes are not expected to grow as much within the City of Tukwila compared to the previous analysis. The slightly lower vehicle traffic growth is reasonable based on the reduction of approximately 14,100 jobs and 100 households throughout the City by 2031 compared to the previous analysis. The new 2031 model run's slightly lower traffic growth is minor as there is only a three percent decrease in vehicle - miles -travelled (VMT) on City streets during the PM period compared to the previous analysis (excluding freeways). • Most of the forecasted traffic volume decreases are south of S 180th Street. This is expected as the growth near Southcenter Regional Growth Center did not change much from the earlier analysis, and most of the employment reduction was in the Tukwila South area, where growth is not as rapid as was anticipated in the earlier forecasts. Overall, City staff felt this area had the least amount of momentum for growth compared to the rest of the City. • No changes are recommended to the proposed transportation capital improvement projects. A review of the previously recommended projects was completed based on the new model run results. In general, all the projects identified in the Transportation Element are recommended to remain because: o Most of the street extension projects were recommended to reduce block size and improve mobility for all modes. These projects would improve street grid connectivity, improve the walkability by breaking up large blocks, and potentially improve emergency response times. While there is a minor decrease in vehicle volumes in the new model run compared to the previous results, projects are recommended to remain to help the City achieve the desired urban form and street network connectivity pattern. o Intersection improvements at various intersections such as adding turn pockets are still recommended as the model shows that turning volumes that triggered the additional turn lanes will not decrease enough to eliminate the need for the additional lanes. o Many projects were identified to enhance pedestrian and/or bicycle facilities. While growth is slightly lower with the new land use forecasts, the need for a 48 City of Tukwila December 30, 2016 Page 5 of 5 comprehensive and connective pedestrian and bicycle network is not altered by the revised land use forecasts. CONCLUSION A new travel model run was completed with revised 2031 land use growth reaflocated to be consistent with PSRC's vision of 15,500 new jobs and 4,800 new households between 2010 and 2031 in Tukwila. Based on the results of the new travel model run, no changes to the Transportation Element project list are recommended. While the traffic growth by 2031 is not expected to be as high as the previous analysis (VMT is lower by three percent), most of the proposed transportation improvement projects are recommended to remain as they were proposed for reasons beyond expanding capacity, including breaking up large blocks for more walkable/bikeable neighborhoods, and filling in missing gaps in the pedestrian and bicycle networks.
