BACKGROUND The NPDES Program requires that the City implement a comprehensive SWMP Plan that complies with the requirements outlined in the City's NPDES Phase II Permit. The City's NPDES Phase II Permit became effective August 1, 2013 and currently has an expiration date of July 31, 2019, A new NPDES Phase II permit will be issued on August 1, 2019 for a five-year term. The Phase II Permit requires the City submit an annual report and SWMP Plan by March 3151 of each year to the Department of Ecology (DOE)_ The annual report outlines the City's progress in meeting permit requirements. The SWMP Plan forecasts activities that are relevant to the NPDES Phase II Permit The SWMP Plan is updated annually to reflect any changes and timelines of the Permit and to provide greater detail as various components of the permit are developed. The Annual Report reflects the activities completed in the previous year. Once the 2018 Annual Report and the 2019 SWMP Plan are submitted to DOE, it will be used to determine whether permit obligations are being met. ANALYSIS City staff has completed the 2018 NPDES Annual Report and updated the 2019 SWMP Plan_ All updates to the SWMP Plan are printed in blue for reference. The 2018 NPDES Annual Report must be signed by the City Administrator and both documents electronically submitted to DOE by the reporting deadline of March 31, 2019.

Manhole 36-165: The sample point is a manhole that conveys runoff from East Marginal Way and is located just upstream of the former Boeing plant Z-line storm sewer (see Figure 1). PBS collected the sample from the channel at the bottom of Manhole 36-165 on January 11, 2018. There was some floating solids observed during the sample collection but no visible sheen. The analyzed sample indicated that levels of total suspended solids (26 milligrams per liter (mg/L)), copper (11.7 micrograms per liter (pg/L)), zinc (60,8 pg/L), pH (6.9), lead (5.39 pg/L) and polychlorinated biphenyls (PCBs) (<0.001 pg/L) were within the adopted benchmark stormwater guidance levels (Washington State Department of Ecology Storm water Sampling Manual A Guidance for the Industrial Stormwater General Permit dated December 2015), Turbidity (50 nephetometric turbidity units (NTU)) was the only exceedance of the benchmark values. The benchmark levels are used as guidance levels, since this sample location is not regulated under a specified stormwater discharge permit. PBS will coordinate the 2nd Quarter-2018 sampling from the manhole location during a measurable precipitation runoff event.

SAMPLE RECEIPT: Samples receipt information is recorded on the attached Sample Receipt Checklist. II. GENERAL REPORTING COMMENTS: Results are reported on a wet weight basis unless dry -weight correction is denoted in the units field on the analytical report ("mg/kg-dry" or "ugfkg-dry"). Matrix Spike (MS) and MS Duplicate (MSD) samples are tested from an analytical batch of "like" matrix to check for possible matrix effect. The MS and MOD will provide site specific matrix data only for those samples which are spiked by the laboratory. The sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The LCS and the MB are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire analytical process. III. ANALYSES AND EXCEPTIONS: Exceptions associated with this report will be footnoted in the analytical results page(s) or the quality control summary page(s) and/or noted below.

Refer to Figure 1 for sample location. Based on the review of precipitation data during the period from July 1 to September 30 of 2018 (i.e., 3r1 quarter) there was not a recorded precipitation event that generated an off -site discharge of stormwater during this period based on precipitation data and site knowledge. Precipitation data was measured at the Seattle Boeing Field (Station KBFI) located approximately 200 feet to the north from the "Z" Line Sampling Location. Data was obtained from the MesoWest website that is through the University of Utah's Department of Atmospheric Sciences (httns://rnesowest.utah.ed i). Upon review of the precipitation data, PBS identified one storm event that had a storm amount greater than 0.1 Inches during business hours. The event was on September 14, 2018 and reported 0,1 inches of precipitation over a 24-hr period. The rain was sporadic and based on weather observations a sampling attempt was not made. The precipitation data for September 14, 2018 is presented in Table 1. PBS will coordinate the 4th Quarter-2018 sampling from the manhole location during a measurable precipitation runoff evert, If you have any questions regarding the enclosed material, please call me at 206.233.9639, Sincerely, Digikally signed by rut , ofreMeganNogetre date: 2018.09.28 15:45:29.07'OD' Megan Nogeire, Project Scientist PBS Engineering and Environmental Inc.

Public Works 6200 Southcenter Blvd Tukwila, Washington Re: 2018 fourth Quarter Boeing Z Line Stormwater Sampling, Tukwila, Washington PBS Project Number 40407.026, City Project No: 91041204 Date Sampled: November 26, 2018 Dear Mr. Larson, PBS Attached please find a summary table of analytical test results, the sample collection field form, and a copy of the laboratory data report for samples collected on November 26, 2018 from the City Stormwater Outfall to Boeing Line "Z" located at the intersection of East Marginal Way South and South 81st Place in Tukwila (manhole 36-165) in Seattle, Washington. The sampling was conducted in accordance with the Stormwater Sampling and Analysis Plan, City Outfall to Boeing Z Line, PBS -March 16, 2016. Identification and visual observations of the stormwater sample point are presented below. A summary of the laboratory analysis results at the sample location is presented as Table 1 (attached). Rainfall amount on this day (24-hour period) totaled 1.36 inches (Source: Weather Underground — Seattle, Seattle Boeing Field (KBFI weather station)). Manhole 36-165: The sample point is a manhole that conveys runoff from East Marginal Way and is located Just upstream of the former Boeing plant Z-line storm sewer (see Figure 1). PBS collected the sample from the channel at the bottom of Manhole 36-165 on November 26, 2018. There was some floating solids observed during the sample collection but no visible sheen. The analyzed sample indicated that levels of total suspended solids (17 milligrams per liter (mglL)), zinc (71.5 micrograms per liter (pg/L), pH (7.6), lead (4.51 pg/L) and polychlorinated biphenyls (PCBs) (c0.001 Iµg/L) were within the adopted benchmark stormwater guidance levels (Washington State Department of Ecology Stormwater Sampling Manual A Guidance far the Industrial Stormwater General Permit dated December 2015). Turbidity (50 nephelometric turbidity units (NTU)) and copper (22.6 pg/L) were the only exceedance of the benchmark values. The benchmark levels are used as guidance levels, since this sample location is not regulated under a specified stormwater discharge permit. PBS will coordinate the 1st Quarter-2019 sampling from the manhole location during a measurable precipitation runoff event. If you have any questions regarding the enclosed material, please call me at 206.233.9639. Sincerely, Megan Nogeire, Project Scientist PBS Engineering and Environmental Inc.

II, GENERAL REPORTING COMMENTS: Results are reported on a wet weight basis unless dry -weight correction is denoted in the units field on the analytical report ("mg/kg-dry" or "ug/kg-dry"). Matrix Spike (MS) and MS Duplicate (MSID) samples are tested from an analytical batch of "like" matrix to check for possible matrix effect. The MS and MSD will provide site specific matrix data only for those samples which are spiked by the laboratory. The sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The LCS and the MB are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire analytical process. Ill.

MONITORING AND ASSESSMENT 10 CONCLUSION 11 80 INTRODUCTION The National Pollutant Discharge Elimination System (NPDES) permit program is a requirement of the federal Clean Water Act. The federal Environmental Protection Agency (EPA) has delegated permit authority to state environmental agencies, In Washington, the NPDES delegated permit authority is the Washington State Department of Ecology (DOE). The City of Tukwila prepared this document to meet the requirements for a Stormwater Management Program (SWMP) Plan as required by the NPDES Phase II Stormwater Permit issued to the City of Tukwila by DOE. The SWMP Plan was developed to reduce pollutant discharges from the City' s Municipal Separate Storm Sewer System (NIS4). Tukwila is defined as a Phase II community by DOE and, therefore, mandated to comply with the requirements of the NPDES Phase II Stormwater Permit. Phase II communities are those that: • Own and operate a storm drain system • Discharge to surface waters of the state • Are in urbanized areas • Have a population of more than 1,000 Municipalities with a population of over 100,000 (as of the 2010 census) have been designated as Phase I communities and must comply with DOE's Phase I NPDES Municipal Stormwater Permit. Tukwila's population is below the 100,000 threshold and must comply with the Phase II Municipal Stormwater Permit. Approximately 100 other municipalities in Washington must now comply with the Phase II Permit, as operators of small "municipal separate storm sewer systems" (MS4). Ecology's Phase II Permit is available on Ecology's website at: http: //www,ecy. wa, aov/programs/wQ/stormwater/municipal/nhaselIww/wwphi ipermit. html Tukwila was first issued a Western Washington Phase II Municipal Stormwater Permit on January 17, 2007 (February 15, 2012 permit term), and June 17, 2009 Ecology modified the permit. On August 1, 2012 the permit term was extended to July 31, 2013. A new five-year Permit term went into effect August 1, 2013 and was modified January 16, 2014. After careful consideration of many factors, Ecology extended the current 2013-2018 Permit term for one year. A new Western Washington Phase II Municipal Stormwater Permit will reissue on July 1, 2019 becoming effective on August 1, 2019 for five years. The Permit allows discharge of stormwater runoff from municipal drainage systems into the state's water bodies (i.e., streams, rivers, lakes, wetlands, etc.) if municipalities implement programs to protect water quality by reducing the discharge of "non -point source" pollutants to the "maximum extent practicable" (MEP), In addition, the City must meet "all known and reasonable treatment" (AKART) through application of Permit specified "best management practices" (BMPs). The Permit also requires by March 31 of each year the City provide an annual report for each previous year's activities that documents the City's compliance with the Permit, Both the annual report and the updated SWMP are to be posted on the City's website no later than May 31' of each year. 1 WOW Engrpp.JECTS1w• 6A PegjoomNPtr;S Program 1,9 sir 12IuIr tnnwr Reports and a wince Warer Mai arinera Pradrnaulllr III Anon/ Appel de YA 1' SWMP PI,n''11I4 SWMP Or,It BIua Wd,1a, dos 81 NPDES PHASE II PROGRAM COMPONENTS The BMPs specified in the Permit are collectively referred to as the SWMP Plan and grouped under the following program components: • Public Education and Outreach • Public Involvement and Participation • illicit Discharge Detection and Elimination • Controlling Runoff from New Development, Redevelopment, and Construction Sites • Municipal Operations and Maintenance • Special condition, Total Maximum Daily Load Requirements a Special condition, Monitoring and Assessment The following sections describe requirements of each program component and the City's planned activities to meet the requirements.

COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD REQUIREMENTS The Permit (Special Condition Section S7) requirements: The Permit (Section S7) requirements apply if an applicable Total Maximum Daily Load (TMDL) is approved for stormwater discharges from MS4s owned or operated by the 9 WVWJlnipROJECTSrn•bitprujcer,M'DESPmgra i001d12lFr rwwlIlcpnrr, and SurrrttWorcrmamgcmcnrrinc.adarmitrpanA2bitSWMPHaiiYSiHISWIG' Oral.' Blot, WilraKdac 89 Permittee. Applicable TMDLs are TMDLs which have been approved by EPA on or before the issuance date of this Permit or prior to the date that Ecology issues coverage under this permit, whichever is later. A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still safely meet water quality standards. The DOE determines the reduction of pollutant discharge needed to be compliant with water quality standards. 6.1 Activities • A TMDL has not been established for the City of Tukwila at this time, consequently no action needed. 7. MONITORING AND ASSESSMENT The Permit (Special Condition Section SS) requires the City to: • Notify DOE of its choice to independently conduct Status and Trends Monitoring and Effectiveness Studies or participate by paying annually into the Regional Stormwater Monitoring Program (RSMP) that will be conducted by DOE. • Pay into the RSMP to implement the Source Identification Information Repository (SIDR) element of the RSMP. • Track and Document additional monitoring conducted and summarize in the 2016 Annual Report. 7.1 Continuing and Current Activities • The City paid a fee of $4.444,00 into the RSMP to have DOE conduct the Status and Trends Monitoring. • The City paid a fee of $7,405,00 into the RSMP to have DOE conduct the Effectiveness Studies, • The City paid a fee of $687.00 into the RSMP to have DOE conduct the Source ID and Diagnostic Monitoring, The total fee of $12,536 is due each year by August 15th until the permit expiration date of July 31, 2019. 10 WV'WCnIIWNQ11:Ct.-DNFrgn.MP!JESFrogranI7n4 andSorfocoWicrMnniasmemI ! nieauIkAnnualHrpon 3oI9gVMPPInmM+1751VWPBruRBlur Wdrno.dou 90 CONCLUSION The current Western Washington Phase II Permit expires on July 31, 2018. DOE extended the current (2013-2018) Permit for one year. The Permit will reissue on July 1, 2019 and become effective on August 1, 2019. This Stormwater Management Program Plan has been prepared to demonstrate efforts and compliance with the requirements of this current NPDES Phase II Permit. This SWMP Plan will be a working document with updates annually until the Permit expires on July 31, 2019. The City's Public Education and Outreach Program is an extension of the previous permit term and will continue to grow with the planned activities. The City of Tukwila will continue to reach out and encourage public involvement and participation in the City's SWMP Plan with the existing notification process. The City's IDDE Program is in place, which includes a spill hotline, and will be reviewed periodically to ensure performance measures are met. The City adopted the 2016 KCSWDM, KCSPPM and revised its standards and codes to include LID and BMPs as the preferred method for development in December 2016, and uses it for controlling runoff from new development, redevelopment, and construction sites. The City of Tukwila's Operations & Maintenance (O&M) is very active in all areas of permit compliance. It should be noted; The 2016 KCSWDM & KCSPPM have new maintenance standards that O&M will follow. Coordination efforts will continue with neighboring jurisdictions and be reviewed to determine where improvements are needed to remove jurisdictional barriers. Total Maximum Daily Load requirements in Tukwila have not been determined by DOE to date. however, the City will prepare for this requirement when it comes due. The City chose to participate in the RSMP collective fund and have DOE administer and conduct the Monitoring and Assessment for this Permit term. Additional information on the City's NPDES program can be found online at http://www.tukwilawa.gov/pubwkslnpdes.html. The public is encouraged to participate in the development of the SWMP Plan.

Henry Hash, Public Works Director BY: Bryan Still, Operations Manager CC: Mayor Ekberg DATE: March 15, 2019 SUBJECT: Surface Water Fund - Renewal King County Regional Stormwater Decant Facility Use Agreement 2019-2023 ISSUE Approve King County Regional Stormwater Decant Facility Use Agreement for 2019 through 2023. BACKGROUND Tukwila cleans approximately 10,000 lineal feet of storm pipe and 1,000 catch basins each year which on average generates 13.2 tons of waste material a month. This waste material must be disposed of properly and the King County Regional Stormwater Decant Facility, located at 155 Monroe Ave NE in Renton, is the closest facility capable of handling the waste material. The first Use Agreement with King County was from 2014 through 2018. DISCUSSION The attached forms are merely a renewal of our Use Agreement with King County and allows us to continue using their facility. The King County site has been approved by the Department of Ecology and allows Tukwila to meet the requirements of Section G10 of the Western Washington NPDES Phase II Municipal Stormwater Permit. This section states that the penrnittee shall not allow collected screenings, grit, solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of Stormwater to be resuspended or reintroduced to the storm sewer system or waters of the state. FINANCIAL IMPACT The King County waste disposal fees have not changed since the last contract. They are $81.00 per facility entry for liquids and $59.00 per ton of solids disposed. The charges will be paid from the Surface Water Waste Materials Disposal budget account 412.01.538.380.47.01, which has $50,000.00 budgeted annually. In the previous Use Agreement, the annual average cost was $13,284.46 and over the last five years the total spent was $66,422.30. As the total cost is over $40,000 for the duration of the agreement, we are requesting Council approval. RECOMMENDATION Council is being asked to approve the King County Regional Stormwater Decant Facility Use Agreement for 2019 through 2023 and consider this item on the Consent Agenda at the April 1, 2019 Regular Council Meeting.

PROGRAM PURPOSE The purpose of the King County Regional Decant Program (Decant Program), operated by King County Road Services Division (KCRSD) is to provide an environmentally sound system for disposing of materials generated from the cleaning of stormwater drainage systems. King County is providing a facility for the disposal of generated stormwater materials that is open to authorized users, including other King County agencies, public agencies, and private companies. Authorized Users of this facility have completed all portions of this Use Agreement, signed by the King County Program Administrator and Finance Manager, and are in good standing with their accounts. In order to operate this system, it is required that all users pay their fair share and follow standard operating procedures as laid out in this Use Agreement, and the Regional Stormwater Decant Facility Program Operations and Maintenance Manual (Operations Manual). The Operations Manual has been prepared to provide a more detailed description of the Decant Facility, use procedures, and allowable discharges. KCRSD currently operates one Regional Stormwater Decant Facility that is open to authorized users, referred to as the Renton Decant Facility. The Renton Decant Facility is located at the King County Road Services Division Headquarters at 155 Monroe Avenue NE in Renton, Washington. Currently, this Facility has a scale system; a series of covered liquid decant settling ponds and other water treatment structures; and a covered stormwater solids storage area. The Facility discharges treated stormwater liquids to the sanitary sewer system under a Waste Discharge Authorization issued by the King County Industrial Waste (KCIW). 2, USE AGREEMENT CONDITIONS A.

Date Page f of 1 107 108 City of Tukwila Allan Ekberg, Mayor Public Works Department - Henry Hash, Director INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committee FROM: Henry Hash, Public Works Director BY: Hari Ponnekanti, City Engineer CC: Mayor Allan Ekberg DATE: March 15, 2019 SUBJECT: BNSF Intermodal Facility Access Prolect Project No. 99510409 Schedule Update and next steps ISSUE Provide an update on the Burlington Northern Santa Fe (BNSF) Intermodal Access Study. BACKGROUND Burlington Northern Santa Fe (BNSF) owns an Intermodal facility that transports containers from trucks to railroad and vice versa. This facility is located within Tukwila city limits in the Allentown community. The intermodal facility is adjacent to 1-5 and just south of King County International Airport, also known as Boeing Field. BNSF calls this facility the South Seattle Intermodal Facility. The City of Tukwila and BNSF jointly funded an access study to determine a potential new route for truck traffic into the intermodal yard. David Evans Associates began the study in March of 2015. The BNSF access study produced a draft report in November 2016. As part of the study, open houses were held, and community input was collected. The following five alternatives were studied; 1. Airport Way S 4. Gateway Drive - north leg 2. South 112th Street 5. 48th Ave S Bridge 3. South 124th Street The draft study indicated that the 48th Ave S Bridge was the preferred alternative. The study remains in draft form. ANALYSIS The findings from the draft study were provided to the City Council in December 2016 after the first round of open houses and community outreach. The alternatives were presented at the August 17, 2017 Open House, with the preferred alternative identified as 48th Ave South Bridge. The next step was planned to bring these alternatives and funding options to the City Council in the fall of 2017. The original next steps for the BNSF Intermodal Study included these options: - Review and finalize the Preferred Alternative and seek Council adoption - Identify and provide funding for preliminary engineering and design of preferred alternative - Continue public outreach and continue SEPA process The draft access study preferred alternative has not been finalized due to new information regarding the 42nd Ave S/Allentown Bridge, which became the top priority for the neighborhood. This bridge provides one of only three access points into the Allentown neighborhood, and is the sole access point for trucks traveling to and from the BNSF Intermodal yard. In August 2017, the City received the 42nd Ave S Bridge Structural Assessment, by TranTech Engineering LLC, which determined that, "...the existing bridge is both structurally deficient and functionally obsolete." The deficiency rating has resulted in the City being forced to post speed and load restrictions in March 2018. 109 IN: 1PW Eng\OTHER\Cyndy Knighton\TIC Agenda Items \3-19-191BNSF\InfoMemoTIC031519BNSFupdateHP.docx Informational Memo Page 2 The City met with BNSF and informed them of these changes. A grant to replace the existing 42nd Ave S Bridge was applied for through the federal Bridge Replacement Advisory Committee (BRAC) in September 2017 but was unsuccessful. The City's adopted the 2019-2024 Capital Improvement Program, which includes funding for the 42nd Ave S Bridge Replacement Project and the City is currently applying for another BRAC grant in 2019. The 2019 CIP does not include funding for the BNSF Intermodal Facility Access Project until after six years. BNSF informed the City that if the 42nd Ave S/Allentown Bridge failed they would have no good alternative route. BNSF also stated that their trucks cannot negotiate the 90-degree turn along the river near Fire Station 53 and that access up the bridge into Skyway and the Martin Luther King Jr Way corridor is already heavily congested. In addition, the steep grade could pose difficulties for large trucks carrying heavy loads. Also of note, the City has been seeking funds for the Strander Blvd Extension Phase 3 for the last 15 years and those funds have still not materialized for construction. As such, seeking funding to replace an existing failing bridge took priority over the new access point, which would likely compete with the Strander Blvd Project for funds.

BNSF explains the GNCC as: "The Great Northern Corridor Coalition is a regional cooperative comprised of eight states, numerous ports, BNSF Railway, and other interested stakeholders along the Corridor. The states of Illinois, Wisconsin, Minnesota, North Dakota, Montana, Idaho, Oregon, and Washington have been collaborating for several years to promote region -wide cooperation, in transportation planning and shared infrastructure investment. The Coalition's primary purpose is to promote regional cooperation, planning, and shared project implementation for programs and projects. Its objective, to improve multimodal transportation system management and operations along the corridor, exactly matches the purpose of the Multimodal Corridor Operations and Management (MCOM) Program." Coalition members are largely made up of state transportation departments in the states listed above, as well as various Ports located within those states. The only municipal participant is the town of Connell, Washington. It is the understanding of City staff that it is BNSF's goal to have the preferred alternative, the 48th Ave S Bridge, included on the list of necessary infrastructure investments that the GNCC is developing. Councilmembers are invited to attend the tour on March 27, 2019 and should contact Hari Ponnekanti, Tukwila's Deputy Public Works Director/City Engineer to RSVP. 110 W:APW EngVOTHER VCyndy Knighton\TIC Agenda Items \3-19-19VBNSF\InfoMemoTIC031519BNSFupdateHP.docx Informational Memo Page 3 FINANCIAL IMPACT Project costs for the preferred alternative, 48th Ave S Bridge, are unknown until preliminary engineering is complete. Best available estimates developed in 2017 were approximately $20 million (adding 30% cost growth per year into 2019, the estimate would be $34 million).

The bridge is composed of a 220-foot-long fracture critical steel thru-truss main span with 30-foot- long concrete T-beam approach spans at each end. The existing bridge is both Structurally Deficient and Functionally Obsolete. A three-tier structure assessment has revealed that there are critical structural elements within the 42nd Ave bridge structure that have deteriorated into poor conditions. The examples of these are the short plinth columns at the bridge approaches, truss gusset plates, and main span deck structure. The bridge is currently nearing the end of its service life and requires strengthening, repainting, deck work, a seismic retrofit, and scour protection, if it were to remain in service. The cost of this work would be prohibitively expensive and would exceed the cost of a new bridge. The proposed new structure will have the added advantages of being a redundant concrete bridge with very low life cycle maintenance costs to the Bridge Program or to the City of Tukwila. A cost estimate for the proposed replacement bridge is presented in Appendix C. Furthermore, it is recommended that until the bridge can be replaced, the interim inspection frequency remains at a six-month interval with special attention being paid to the critical structural elements identified in the structural analysis presented here. A monitoring plan has been developed and will be implemented by the City of Tukwila until bridge funding can be secured and the bridge can be replaced. 113 Table of Contents Page 1. Introduction 1 2.

INTRODUCTION The 42nd Avenue South Bridge is a 3-span 280-foot-long bridge built in 1949. The bridge is composed of a 220-foot-long fracture critical steel thru-truss main span with 30-foot- long concrete T-beam approach spans at each end. The existing bridge is both Structurally Deficient and Functionally Obsolete. The plans for the existing bridge are available under the "Records/Plans" tab in the WSDOT Bridge Inspection Application. The bridge is located within the City of Tukwila on a sharp bend of the Duwamish River that produces turbulent high velocity flows at the truss abutments. These frequent flows have caused scour damage at the bridge abutments and at the north approach roadway. Because the bridge foundation depths are unknown and there is active scour, the City has implemented a scour Plan of Action (POA) for high flow events. Additionally, existing riprap at Pier 2 is either washing away or is falling into a scour hole developing on the river side of the pier. The bridge is the only access for the BNSF intermodal yard located at the end of South 124th Street as other the yard prohibit trucks. As a result, the bridge has been subjected to an unusually high percentage of truck traffic constantly crossing the bridge around the clock. The City of Tukwila has struggled for years to maintain the bridge. Maintenance projects includ a major paint project in the mid-1990's and a significant project to rebuild the north bridge approach after erosion, caused by scour, threatened the existing roadway. This problem is currently resurfacing even after the City installed a sheet pile wall to protect the approach. A dramatic illustration is the sinking of the north approach guardrail posts with a section of the rail currently at almost ground level. There is also the ongoing problem of keeping the bridge clean enough to perform valid inspections. Cleaning the bridge adds significant cost to the already expensive fracture critical inspections as well as adding equipment scheduling complications. In addition to the substructure problems, the deck and floor system are in distress as evidenced by significant loud floor system creaking and deck panel banging under traffic. These problems have been reported by bridge inspectors and Tukwila 1 115 Maintenance for years. These noises cannot be associated with specific damage at this point but are worrisome in a fracture critical bridge subjected to extreme fatigue stresses by the heavy truck traffic. The bridge is currently nearing the end of its service life and would require strengthening, repainting, deck work, a seismic retrofit, and scour protection, if it were to remain in service. The cost of this work would be prohibitively expensive and would exceed the cost of a new bridge. The proposed new structure will have the added advantage of being a redundant concrete bridge with very low life cycle maintenance costs to the Bridge Program and to the City of Tukwila. 2. STRUCTURAL ASSESSMENT The structural assessment activities performed as part of this study have a three-tier approach that is described in detail in the following sections: 2.1 Tier 1 - Bridge Inspections The 42nd Avenue South Bridge has been inspected on an increased frequency (a reduced frequency duration) since 2014. The frequency change started at 12 months and is now set at a six-month interval for Interim Inspections. These inspections focused on monitoring the damaged short concrete plinth columns supporting the approach span girder bearings at piers 2 and 3 and bridge gusset plates. Since 2014, the bridge has also undergone several in-depth and routine bridge inspections with the most recent being in spring of 2017. The observations and data obtained from these inspections has been utilized in a new comprehensive load rating per WSDOT and AASHTO recommended Load Factor Rating requirements that includes gusset plate and Emergency Vehicle (EV) ratings. The new load rating is described in further detail in the following sections. The in-depth and interim inspections, some of which were performed with UBIT special access and after bridge cleaning to ensure a valid inspection, indicate that approximately one third of the truss structure is now in BMS Condition State 3 and that the Substructure Overall Condition rating is at a 4-code because of critical damage to the concrete plinth columns at Piers 2 and 3. Please see Appendix A for the latest Inspection Report. The resulting Sufficiency Rating has dropped in steps as the inspection and analysis has progressed, reaching its current level of 7.56 SD. The new load rating indicates that posting of the bridge for legal loads, single hauling vehicles, and emergency vehicles is necessary. The City is currently implementing the NBIS load posting requirements. 2 116 2.2 Tier 2 - Structural Assessment — Piers 2 and 3 Column Damages The City of Tukwila has initiated a structural evaluation of the short concrete approach span, girder support columns at Piers 2 and 3. The deterioration of these columns was listed as one of the main reasons for the reduction of the Substructure Overall Code to 4 (i.e., Poor Condition) as reported in the 2015 bridge inspection report. This engineering analysis is supporting information to justify the request for bridge replacement funding from the WSDOT administered Local Bridge Program. The results of the structural analyses are summarized below. Eight short plinth columns support the concrete T-beams of approach Spans 1 and 3. The girders sit on a rocker bearing installed on top of each plinth. These bearings are completely frozen by pack rust and deterioration. In addition, the rocker bearings for the truss span at Pier 2 appear have been frozen or locked in the expansion direction for years. Each column has six number seven vertical shear friction bars at their interface with the pier wall. First, the plinth columns were analyzed for temperature and vehicular breaking force induced stresses. These results showed that the demand forces are not large enough to create the observed damage. Next, seismic forces were analyzed and were shown to be large enough to yield the interface of the short columns and the piers . wall as the forces are transferred through the , semi rigid link caused by the frozen _ bearings. This condition is accentuated at the obtuse northwest corner of the Pier 3). The existing bridge design, which includes an extreme skew of 38°, puts these columns at additional risk from seismic events as well as from normal temperature and traffic forces as torque forces are developed and added to the high shear forces. The interface cracking has been documented since 2001 (upper photo) and the cracks are currently opening and starting to spall. In addition, there has been documented evidence for many years of the deterioration of the reinforcing steel as evidenced by rusty leaching. These problems may have been initiated during the April 29, 1965 South Sound Earthquake and were likely compounded by the February 28, 2001 Nisqually earthquake. However, the damage is aggravated daily by the constant truck traffic and seasonally due to normal temperature corner (i.e. Column Plinth 3A at 3 117 forces. This constant cyclical bombardment of Column 3A make it a failure risk for Span 3. Since the rocker bearings located on the plinths are all completely frozen, there is a semi -rigid link allowing these high magnitude forces to be transmitted through Span 3 to the North Abutment, Pier 4. Again, due to the bridge's large skew, a concentration of force is toward the northwest side of the abutment as illustrated by the damage at this location. This concentration of force may play a role in the continued settlement issues of the north bridge approach roadway at the steel sheet pile wall repair mentioned above. 2.3 Tier 3 - Updated Load Rating Analysis A gusset plate load rating update was performed in November 2014 that did not consider the coding changes made during the condition assessments performed in the Spring of 2015. A new comprehensive Load Rating Report was completed in August 2017 as part of the funding analysis as well as to evaluate the bridge for emergency vehicles. The new load rating indicates that the deck and gusset plates have ratings that are below 1.0 with respect to the legal trucks and that the gusset plates control. TranTech has ranked the gusset plates by their criticality and has identified the failure mechanism of each plate. This information will be used to focus the gusset plate inspection during future interim and routine bridge inspections. The rating outcome has further reduced the bridge's capacity and the resulting Sufficiency Rating. A copy of the Summary Sheet from the new load rating is attached in Appendix B. 3. CONCLUDING REMARKS A three-tier structure assessment has revealed that there are critical structural elements of the 42nd Ave bridge structure that have deteriorated to poor conditions. Examples are the short columns at the bridge approaches, truss gusset plates, and main span deck structure. Rehabilitation of this structure would be prohibitively expensive and a bridge replacement is recommended. A cost estimate for this bridge replacement is presented in Appendix C. Furthermore, it is recommended that until the bridge can be replaced, the interim inspection frequency remains at a six-month interval with special attention being paid to the critical structural elements identified in the structural analysis. A monitoring plan has been developed and will be implemented by the City of Tukwila until bridge funding can be secured and the bridge can be replaced. 4 118 APPENDIX A I Current Inspection Report TRANTECH IEnginPc ring LLC 119 Status: Released CD Guid: 4305b7a6-8599-4765-87ce-c492bac836bd BRIDGE INSPECTION REPORT Printed On: 8/17/2017 Agency: TUKWILA CD Date: 7/27/2017 Program Mgr: Roman G.

There are a few rust spots where failed paint has exposed bare metal. Seam rust is bleeding through along edges of built-up members. Moss growth on some diagonal/vertical members. 1663 The Deck Overall code was downgraded based on deck and floor system deterioration. The deck panels are non -composite and are loose and banging on the floor system under traffic. In addition, the floor system is creaking and groaning under load. These problems are not revealing themselves in recordable damage but the loose deck panels and lack of continuity was taken into account in a new load rating update. 1676 SUBSTRUCTURE Code reduced to 4 due to condition of concrete plinths under rocker bearings at piers 2 and 3. Pier 2 plinth 2A, and 2B have open cracks at interface with pier cap. All plinths have large spalls with exposed rebar along edges, several are spalled under bearing plates. Pier 3 plinth 3A and 3B have open cracks at interface with pier cap. Several plinths have spalls with exposed rebar. Unknown pile tip elevation of piles supporting Piers 2 & 3. Channel thalweg is near pier 2, riprap is scattered. 1680 SCOUR , OFFICE Scour analysis done in 2014. Since pile tip elevations are not available, the scour code = "U". The channel is centered under L3-East and is slightly aggradating at piers 1, 2 and 3. Calculated contraction scour is 0.6 feet, local pier scour ranges between 6 feet and 13 feet depending on angle of attack.

This facility is also known as South Seattle Yard. BNSF Railway also sponsored this study, The existing access to the intermodal facility uses 42nd Avenue 5 and 5 124th Street. 5 124th Street is also a residential collector street serving the community of Allentown. Several residential homes with driveways are located on S 124th Street, as is the Tukwila Community Center which houses an aquatic center, meeting rooms, classes and activities for all ages, and playground and ball fields. This study did not create new alternatives but used alternatives that were developed by previous studies. A total of five alternatives were studied: Airport Way S, 5 112th Street, S 124th Street, Gateway Drive — North Leg, and 48th Avenue S. Several desktop researches were performed as part of this study. These researches included critical and sensitive areas, fish and wildlife, water resources, hazardous materials, geological and soils, and cultural and historical resources. A scored screening matrix was developed collaboratively between the City of Tukwila, BNSF Railway, and David Evans and Associates, Inc. The matrix was presented to Tukwila City Council as well as to the public for their feedback on the screening matrix criteria. The public was allowed to provide feedback via an on-line open house and an in -person open house. Representatives from Tukwila, BNSF Railway, and David Evans and Associates, Inc. met to score each alternative using a numerical scoring system from 1 to 9. The score for each criteria was added, and the lowest score is the preferred alternative. Based on the scoring result, the 48th Avenue 5 alternative is the preferred alternative.

The City identified a preferred alternative route and shared it with the community at an open house on August 17, 2017. Summary The City of Tukwila hosted an in -person open house at the Tukwila Community Center on August 17, 2017. The in -person house accompanied an online open house, which included the same information as the in -person open house and was available from August 15 - 28, 2017. Notifications The project team advertised the in -person and online open houses in early August 2017. Notifications included the following: • Postcard sent to the Allentown and Duwamish neighborhoods • Emails to the City's project listsery o Listsery includes community members, business and property owners, other interested parties • Flier emailed as attachment to Allentown and Duwamish neighborhood listservs by neighborhood leaders • Facebook and Twitter posts on the City's social media accounts Attendance and visitor statistics • In -person open house attendance: 42 • In -person comment forms completed: 20 • Online open house visitors: 32 • Online surveys completed: 12 • Overall number of participants: 74 Engagement Methods In -Person Open House The City gathered shared information about the preferred alternative and other considered alternatives during an open house at the Tukwila Community Center on August 17, 2017, from 5:30 p.m. to 7:30 p.m. Participants viewed informational boards that described the project purpose, schedule, alternative and preferred routes, screening criteria and environmental process. Project staff were on hand to answer questions. Participants contributed comments via comment cards. Comments received at the open house are shown in Appendix 1 and summarized below. Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 136 In -person open house participants give feedback on comment cards. Online Open House In order to reach Tukwila businesses and residents who were unable to attend the in -person open house, the City advertised an online open house, available 24 hours a day, seven days a week, starting August 15 and ending August 28. The online open house included the same information as at the in - person open house and a survey that gathered specific feedback in a similar fashion to the comment boxes at the in -person open house. Comments received through the online open house are shown in Appendices 2 and summarized below. Feedback Overview Several themes emerged from the input received through 32 comments and surveys: • Those who supported the preferred alternative (15) stated a number of reasons for their support, including moving the truck route to a commercial street and away from residences, access/proximity to I-5 and current residential impacts on 124th. • All residents who said they live along or near the current access route who participated (4) supported moving the truck access route to another street. • Those who opposed the preferred alternative (4) stated increased traffic, business impacts and residential impacts as reasons for their opposition. • Several participants urged the City to study or investigate cost (4) and traffic (3). Several participants also expressed interest in potential environmental impacts (3). Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 137 Next Steps All feedback presented here is being provided to the project team for consideration. The study and proposed route will be presented to City Council in the fall of 2017. One participant requested specific follow up regarding business impacts on 48th Ave S: Quinn Closson, 360-607-8178, qclosson@pape.com. Appendices 1. Comments gathered at in -person open house 2.

Minimum public $, maximum private funding. x Angela Steel angelasb13@hotmail.com I prefer the 48th Ave S option as the least impactful to residential properties in Allentown and Duwamish. This option keeps semis on existing truck routes w/out creating new roads through environmentally critical areas or private property. *Also need noise wall along edge of railyard. [unknown] [unknown] My first choice BNSF move out completely. Second choice I prefer 48th Ave S. Build wall to control noise and shaking control. x Mary Fertakis [unknown] Thanks for all the work that has been done on this. The grid was particularly helpful - very concrete information and easy to understand. The original study in 1990 shows that the 48th st option was the least expensive and made the most sense. It is the same in 2017. Seems pretty clear that this is still the direction to go. x x David Shumate David@propeldesigns.com The 48th Ave and Bridge looks like the best one! x x Sean Albert seanalbert2001@hotmail.com I think the preferred 48th ave south route is by far the best alternative!! Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 139 x Patty Cokus pcokus@hotmail.com I agree wholeheartedly with the preffered study route where it impacts all identified impact criteria the least and is the least expensive. Thank you for working on this and advocating for community input and gathering feedback. The preferred route makes the most sense for all. x [Illegible] [unknown] I think the preferred option makes the most sense of those presented. It takes the traffic completely off residential streets and on to a commercial street that already accomodates semi - truck traffic. x Lucia Nilo Itannilo@hotmail.com I hope this project gets look at seriously as I really enjoy my home at 124th - but the vibration of the trucks in and out 24-7 is really bad and nuisance. It shakes our house especially when sleeping - the NO -Build option: S 124th should not be an option. x Wilfredo Nilo wznilo@gmail.com We live by 124th ave which is active for semi -trucker. Since we moved here from September 2016 we felt a massive vibration everytime those truckets pass by. We live in a brand new home and it created major cracks in aour garage. We worried whats gonna happen next. x Oscar Uceda o.uceda@yahoo.com We would like to support the prefer alternative for the trucks route coming in and out of the BNSF Railroad Yard facility in Allentown. Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 140 x x Becky [Illegible] becarosep@aim.com Concern the increase in traffic from now and 20 years down the road on the 48th ave purposal. What effects it will have on the businesses on 48th (widening roads etc) Residents being impacted by not being able to get access to the businesses they already go to. x Morgan Llewellyn mllewellyn@ccim.net I'm wonderng how the project will be funded particularly in light of the right away acquisitions required by the preferred route. It appears the northern route would have the least impact on residential AND commercial businesses. x Todd Jones rain1916@comcast.net I stronly oppose Gateway Drive option and 124th st options. I do like the 48th st option or others to the north. x Hanice Ludington shofarJCL@gmail.com My preference is Airport Way s x [Illegible] [Illegible] The road should go out the north end. I live on 51st (across the street from the flat bed trucks, and am concerned about where the railroad will put the road inside this yard. Will trucks have to be removed and trailers [illegible]? And if so, where will they go? It is close to our homes, your moving one road to another. x Linda McLeod sam.linda.mcleod@gmail.com No on Gateway Dr. Divides BECU campuses, has many employees + customers x [unknown] [unknown] Airport SO. (BEST) [sic] Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 141 x I live in 122nd st. I hope the 124th s st. would be closed as enterence of BNSF or trucks facility. The impact to our Edna edna0801@gmail.com home and neighborhood is Derr[illegible] terrible, the house vibrates each time; lots of noise; and traffic gets crowded. 48th st is great alternative for the BNSB enterence. Steven steve@xmrine.com We'd like to see a traffic impact study done on inerurban and exit 156 off 1-5. Please go to fife and see the issues they have and avoid that happening to us. Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 142 Appendix 2: Comments from Online Open House Note: comments are verbatim as written. Comment 1. Will all trucks no longer use 124th st ? 2. Will there be entry and exit capability from 50th PL S/129th street? we must have the capability to enter and exit from 50th PL S/129th street. Please make sure this option available. Thanks for your consideration How much will this cost? What about an option to improve the 42nd st. bridge by the community center and do some mitigation on the streets that the trucks drive down, such as widening the shoulders of the street, side walks and maybe even some sort of sound barrier? How is this project prioritized compared to needs in other neighborhoods such as sidewalks and road repair? I am an employee of BECU and believe that the 48th Ave So. preferred option is by far the best choice. Not only from a cost perspective but also from a life safety, employee/member environment and the disruption of multiple businesses/residential and land/building value standpoint. The 48th Ave So. option already houses a street with truck yard access and would be a much easier way to execute on this initiative. While I know this still impacts some, it is the reasonable choice and should be adopted. I am not only a Tukwila resident but also a Tukwila business owner that would be greatly affected by the "preferred" route of 48th AVE S. The overall impact on the businesses along this route would be devastating. People are already frustrated with the current amount of big trucks coming along 48th. We are already lacking suitable gas stations in Tukwila. Please don't make them impossible to get to. Tukwila is a growing city and the north side (Airport way) of it is already industrial. Interurban Ave is an incredibly popular thoroughfare for many people going south/north and the 2 gas stations on 48th Ave services more than half of those people. Please reconsider 112th or Airport way as the better alternative that will impact our growing city the least amount. Thank you. I am very happy that the city is analyzing other options for the truck route into the BNSF yard. The current route is not sustainable. My family prefers the 48th Av S option since it uses an existing commercial street and is least impactful to residential communities and the environment. I would like you to heavily factor in the environmental impacts the other two northerly options would have on wetlands and existing greenspaces.Will the Airport Way option impede future Light rail/Sounder station location planning efforts? How will the different entrance options impact yard operations? Currently, the BNSF yard is very noisy 24/7 with back up beepers. Will these operations shift or diminish with the varying options? Can the city proceed with pursuing the noise wall installation along the railyard boundary? I think this will make a significant improvement to the quality of life in Duwamish and Allentown. thank you I represent The Pape' Group, Inc. who owns the Ditch Witch dealership on 48th Ave, South. I understand there will be significant traffic impact during construction. I don't think we're overly concerned about that. However, I'd like a little more information on the traffic study or estimates on additional traffic impact on 48th Ave. South after completion of the project. Also, will there be any improvements done to the 48th Ave road itself? Finally, is there something I'm missing that you think we should be concerned about as a business right on 48th Ave? Thanks, Quinn Closson 360-607-8178 qclosson@pape.com Tukwila BNSF Access Study — Preferred Alternative Outreach Summary DRAFT 143 I wish that this 124th St. access be change to a different access ASAP because we moved here in a new home development last year 2016 of Sept. which we are not aware about this 124th St. right beside our house is the major access for truckers. We encountered 24-7 of a massive vibration like an earthquake multiple times everyday and we felt scary that our house may collapse one of this day. So far we had a multiple long cracks in our garage and hopefully will not affect the foundation. We live right by the stop sign where those truckers heading out from BNSF gate and also for coming in. That really distract us everyday. There's a time when some of the truck driver lost their focus on the stop sign especially in the evening and they made an emergency brakes and it shakes the ground so bad and it vibrates our house also. I Believe that 48th Ave S is the best alternatives route for the truckers. I work at BECU. The Gateway alternative would have a negative impact on our members who come into our Tukwila Financial Center to conduct their personal business (primarily retail banking, trust services, and investment services). We are about to engage on a Gateway campus upgrade and a truck route cutting through the middle of it would have a negative impact on our employee experience and may have a negative impact on our ability to recruit and retain employees. Given the existing land use abutting most of your preferred alternative (gas stations, commercial, etc.). I can see the potential noise downside for a hotel (but it's already next To 1-5 and a busy off ramp so marginal impact seems moderate). I would like to avoid having another bridge over the river and prefer this option: S 112th Street Thank you. Thank you for considering all options and explaining the reasoning. What timeframe are you looking at for construction of the new bridge and roadway. What impact will there be on the existing Interurban Bike/Walking Trail both during construction and upon completion. Will traffic studies be done to work on minimalizing impact at the intersection for traffic on Interurban and from the off ramp on 15? This route makes the most sense as it is a quick, direct route off of 1-5, drives through a commercial area only and does not affect the public's experience of their greenspace, except for a small segment of the bike trail. I fully support this preferred route. What are the costs? How it will be funded?

Christy ❑'Flaherty, MMC, City Clerk Published Seattle Times: February 26, 2018 151 THE CORRIDOR Overview Stretching from Chicago to ports on the Pacific Northwest, the Great Northern Corridor is an east -west artery of commerce that supports the economic vitality of more than 38 million Americans across eight North Central and Pacific Northwestern states. Thousands of manufacturers, ranchers, farmers, miners, timber and lumber businesses and energy producers rely on the Corridors multimodal transportation options. The unifying thread and primary focus of this Corridor is the rail network stretching from the Great Lakes to the Pacific Northwest, and other logistics infrastructure such as highways, ports, and terminals. Every day, Americans across this system work together to produce and deliver vital products for their neighbors and the world, such as factory workers in Illinois making tractors for farmers in Montana to grow wheat that longshoremen in Washington load onto ships for ultimate delivery to dinner tables in Japan. 152 THE CORRIDOR History In the late 1800s when railroad magnate James Hill created the Great Northern Railway Company, the northern United States from the Great Lakes to the Pacific Ocean was untapped territory, holding the promise of entrepreneurial dreams unfulfilled. As an example of that entrepreneurial spirit, the Great Northern Railway was constructed and was the only transcontinental railroad built without using federal dollars or donations of federally owned land. It has maintained that spirit for over 100 years because its history and operations are rooted in solid economic principles and performance. The Great Northern merged with other railroads, and, over time, became a key element of the BNSF Railway Company as we know it today.
