City ofTukoril Attain Ekberg, Mayor Public Warks Deportment Hari Ponnekanti, Director/City Enginc-er- INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Services Committee FROM: Hari Ponnekanti, Public Works Director/City Engineer BY: Brittany Robinson, Grant Analyst CC: Mayor Allan Ekberg DATE: May 13, 2022 SUBJECT: Green River Trail Improvements Project Project No. 91810403 PSRC Transportation Alternative Program Grant Award and Acceptance ISSUE Acceptance of a Transportation Alternative Program (TAP) Grant Award with the Puget Sound Regional Council (PSRC) in the amount of $989,000 for the Green River Trail Improvements Project. BACKGROUND The Green River Trail Improvements Project is the final section of a larger vision to provide safe and equitable access for pedestrians and cyclists from Tukwila Station to the Tukwila Transit Center and greater Southcenter District. This project aligns with other bicycle and pedestrian infrastructure projects, including the Tukwila Urban Center (TUC) Pedestrian - Bicycle Bridge Project, which was completed in 2016; and the related Baker Boulevard Non -Motorized Improvements Project, which was completed in 2018. Due to funding constraints, the construction of the Green River Trail Project was never completed. DISCUSSION TAP grant funding is available every other year for cities and counties to build bicycle, pedestrian, and other community- based transportation improvements in the region. On March 25, 2022, the PSRC provided the City with notice of award for $989,000 in TAP grant funding for the construction phase of the Green River Trail Improvements project. TAP grant funding will complete the final segment of the Green River Trail Improvements project, which intersects with Christensen Road. The project will widen and pave 700 feet of trail, construct a new pedestrian plaza, and add way -finding signs to major destinations, illumination, and security cameras. The project is fully designed and permitted, and the grant funds will be used exclusively for construction related activities. The Green River Trail project permits were combined with the Tukwila Urban Center (TUC) Pedestrian -Bicycle Bridge Project and are set to expire at the end of year. Construction must be completed by the end of 2022, or new permits will be required, which would increase the project budget and significantly extend the project timeline. Staff will obligate funds to begin construction in August to meet project completion goals. FINANCIAL IMPACT The cost to complete the Green River Trail Improvements project is $1,297,000, which is based off the most recent Engineer's Estimate. The Puget Sound Regional Council is awarding the City $989,000 and the City match required to complete the project is $308,000. The 2021-2022 project budget is sufficient to cover the match. Cost Estimate 2021-2022 Project Budget TAP Grant Award $989,000 $308,000 City Match 308,000 Project Total $1,297,000 RECOMMENDATION Council is being asked to formally accept the Transportation Alternative Program (TAP) Grant Award with the Puget Sound Regional Council (PSRC) in the amount of $989,000 for the Green River Trail Improvements Project and consider this item on the Consent Agenda at the June 6, 2022, Regular Council Meeting.

On January 24, 2022, Council approved contract 22-012 with KPG for the design of the 2022 Small Drainage Program. KPG was selected as the best firm to meet the project requirements from a short- list of firms selected from the current MRSC. DISCUSSION This contract amendment will add construction management services to KPG's existing contract. KPG will provide field engineering, inspection, technical support, submittal review, contractor communications (RFIs) and coordination, documentation compliance, materials testing and record drawing production. KPG has designed the Annual Small Drainage Program since 1991 and Public Works continues to be very satisfied with their work. KPG also has an unparalleled knowledge of the work scope at the three 2022 sites. FINANCIAL IMPACT The 2022 Small Drainage construction management (CM) budget is $100,000 and is sufficient to cover the costs of Amendment No. 1 in the amount of $99,872.00.

BACKGROUND The Transportation Improvement Program (TIP) is updated annually as required by the Revised Code of Washington (RCW) and must be adopted by June 30th of each year. The TIP is adopted by resolution after a public hearing at the local agency level and incorporated into regional and state TIPs. The TIP is primarily a financial planning document for projects competing for grants. Any project submitted for federal grant funding must be included in the local, regional, and state adopted TIPs. The TIP is a rolling plan showing various funding sources: grants, developer, and local funds. Projects "roll" as funds or stages occur (design report, final design, and construction). Tukwila's TIP and Capital Improvement Program (CIP) list many of the same transportation -related projects. The TIP generally lists only those transportation -related projects planned within the next six years that are deemed regionally significant or that have grant funding awarded or expected. The TIP is scheduled for adoption on June 27, 2022. ANALYSIS The attached spreadsheet is the "Draft" 2023 - 2028 TIP and was created by modifying the 2022 - 2027 TIP to add or remove projects and adjust project costs. No prioritization was assigned, and the list of projects is presented in alphabetical order. Only one project was removed because it is expected to be completed before the end of this year. Deleted: West Valley Highway/Longacres Way FINANCIAL IMPACT None.

BACKGROUND The National Pollutant Discharge Elimination System (NPDES) requires the City to adopt regulations and other requirements outlined in the City's NPDES Phase II Permit, which became effective August 1, 2019. These requirements include: • No later than June 30, 2022, adopt an ordinance or other enforceable mechanism that addresses runoff from new development, redevelopment, and construction site projects. • No later than August 1, 2022, permittees shall adopt and make effective an ordinance(s), or other enforceable documents, requiring the application of source control best management practices (BMPs) for pollutant generating sources associated with existing land use and activities. ANALYSIS To fulfill the first stated requirement, staff recommends adopting the 2021 King County Surface Water Design Manual (KCSWDM) and the 2021 King County Storm water Pollution Prevention Manual (SPPM). The City currently utilizes the 2016 KCSWDM, which is recognized by Ecology as fulfilling this permit requirement and is embedded throughout to in City code. On the second requirement, the City has created language that requires application of source control BMPs. FISCAL IMPACT There will be no fiscal impact.

The site extends approximately 675 feet upstream along Gilliam Creek. The project will remove fish barriers and restore fish access to Gilliam Creek while maintaining or improving existing flood protection. This project will restore access and shoreline habitat as part of a watershed -wide effort to restore ESA -listed Chinook salmon and will be designed to allow juvenile fish access between the creek and the river, which are tidally influenced. Habitat enhancements will occur both upstream and downstream of the existing culvert. The project will also address recreational, aesthetic and educational opportunities and constraints associated with the adjacent Green River Trail and trailside park area. The project area is constrained by local roads, 1-405, regional and local utilities and commercial land use. SCHEDULE: The anticipated project schedule is to have notice to proceed in late June and preferred alternative selected in November 2022. If requested, during the Alternatives Analysis, Otak will prepare a scope amendment for 30% Design of the preferred alternative that will continue from December 2022 into early 2023. The Scope of Services is described in detail in the following sections. 1.0 Project Management and Coordination 1.1 Coordination with City Otak will coordinate with the City of Tukwila on a regular basis by phone and email to keep the City's project manager informed about project progress, project issues and schedule. Otak will assist in scheduling project related meetings, reviews, and other coordination activities needed to keep the project moving forward. Regular communication with the City will occur on a bi-weekly basis, and a status report will be provided to the City before each meeting summarizing the status of action items and deliverables. 1.2 Preparation of Work Plan Otak will prepare a preliminary Work Plan prior to the project kickoff meeting. The Work Plan will define project goals and design criteria, communications, deliverables, and quality control requirements. A project schedule (MS Project) will be developed and maintained as part of the Plan. The Work Plan will be updated after the project kickoff meeting, subject to comments received. The Plan will include a Risk Register that will summarize key issues that are at risk of impacting the scope and schedule and the mitigation strategy. Otak — Scope of Work 122 1.3 Meetings This scope assumes a total of four (4) one and a half-hour online meetings between the City and Otak attended by three (3) Otak staff. The purpose of these meetings will be to discuss Otak's initial recommendations and key project issues that will guide the design. The meetings included within this Task do not include individual meetings identified in subsequent tasks below. 1.4 Project Monitoring and Reporting Project monitoring and reporting will include the coordination of design team members, internal project scheduling, and the preparation of a monthly progress report and a monthly billing statement. TASK 1 DELIVERABLES • Weekly project reports submitted to the City by email (electronic PDF file format) • Work Plan • Schedule Updates • Meeting minutes for up to four key meetings during Phase Ito clarify and document project decisions • Monthly progress report and monthly invoice TASK 1 ASSUMPTIONS • The duration for Phase I of the project is assumed not to extend beyond March 31, 2023 Project management services for Phase II of the project will added later under the Phase II scope. • Project schedules and work plans will be updated every two weeks. 2.0 Intake Review 2.1 Data Review and Desktop Assessment Otak will obtain and provide a desktop assessment and evaluation of all available information from the City regarding the existing levee system, stream, roadway, and outfall; including but not limited to GIS data, design calculations, connecting stormwater conveyance, as -built drawings, maintenance records, etc. Otak will also review the preliminary design work performed at the site by others including: Y Hydrologic Model electronic files Y Hydraulic Model electronic files (HEC -RAS) Y Topographic survey information including ACAD electronic files Y Environmental Assessment Memos As described under Task 5 below, we assume that the previous Hydrologic Model, by others, will be adequate for design and will only require updates by Otak. If the files are not able to be imported by Otak for updating, the City will be notified of additional work required for full development of new modeling files. 2.2 Initial Site Visit An initial site visit to the project will be conducted to visually verify the site conditions and issues identified through the desktop review. This visit will include meeting onsite with the City engineering staff and/or maintenance personal to discuss their observations about the facilities on-site. Initial site visit will include review of site conditions such as: • Condition of existing infrastructure such as the culvert, flap gate, headwalls, and roadway retaining wall • Existing channel stability • Adjacent private/public improvements that will require restoration if disturbed • Construction access issues Otak — Scope of Work 123 • Surface evidence of existing underground utilities • Existing topography To maximize efficiency, we assume that the field visits and on-site meetings with City staff for this Task can be performed on the same day. The site visit will be attended by up to four Otak staff including a Hydraulic Engineer, Structural Engineer, Wetland Ecologist, and Geomorphologist. 3.0 Environmental/Permitting Support 3.1 Wetland and Stream Delineation and Habitat Assessment Report Otak will conduct wetland and stream delineations and stream habitat assessment within the identified project area from the Green River to the next culvert upstream of and west of 66th Avenue South. Stream habitat will be characterized to document baseline conditions to support restoration design and permitting pathways for regulatory compliance. The delineated wetland boundaries and ordinary high water (OHW) line will be marked with flagging or wire flag stakes as appropriate, and surveyed by Otak. The area for the wetland and OHW flagging will extend 150 feet upstream and downstream from the tide gate along the left bank of the Green River, and west of 66th Avenue South along Gilliam Creek up to the next culvert and between 1-405 and Tukwila Boulevard. Wetlands will be delineated using the Corps of Engineers Wetlands Delineation Manual (1987) as amended, and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains Valleys, and Coast Region (2010) as required by King County, WDFW, Ecology, and the Corps of Engineers. All delineated wetlands will be rated using the Washington State Wetland Rating System for Western Washington — 2014 Update (Ecology Publication No. 14-06-029) to classify wetlands and determine buffer widths per the City of Tukwila's critical areas ordinance (TMC 18.45). The OHW line on the Green River and Gilliam Creek will be delineated in accordance with USACE Regulatory Guidance Letter 05-05 (Ordinary High Water Mark Identification) and Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Ecology 2016). Stream habitat surveys will be conducted on Gilliam Creek to document existing conditions using methods modified from Timber, Fish, and Wildlife protocols (Schuett-Hames, et al. 1999). Quantitative and qualitative field measurements will be recorded to assess habitat unit complexity, wood quantity and dimensions, spawning gravel, pool quality, canopy cover, and channel geometry. Otak will prepare a Wetland and Stream Delineation and Habitat Assessment Report in accordance with state and federal standards, including special flood hazard areas, wetlands, and fish and wildlife habitat conservation areas (FWHCAs). 3.2 Permitting and Environmental Review Memorandum Otak will prepare a Permitting and Environmental Review Memorandum (PERM) based on the preliminary design for the project. The PERM will include a summary of existing conditions and describe anticipated impacts to regulated environmental areas. A regulatory compliance and permit strategy for local, state, and federal agencies will be developed to authorize future construction. The PERM will address scheduling implications and assess mitigation needs based on project impacts for mitigation planning prior to submitting applications. The PERM will also address strategies for compliance with the Endangered Species Act, Magnusson Stevens Fisheries Act, and Section 106 of the National Historic Preservation Act. Potential for a Fish Habitat Enhancement Project designation will be evaluated. This task includes coordinating with the USACE regarding the applicability of "Section 408" for work on federally authorized projects as required under the Rivers and Harbors Act of 1899.

The conceptual mitigation plan will be prepared as a technical memorandum; permit application drawings are not included in this task. On-site mitigation opportunities will be identified in the tributary corridor for the conceptual mitigation plan. Construction in -water work methods will be incorporated, such as timing restrictions and work area isolation to minimize potential adverse impacts to aquatic resources in the tributary. The conceptual mitigation plan will document avoidance and minimization measures taken during development of the preliminary design to reduce project impacts to wetland and stream habitats. 3.4 Geomorphic Assessment 3.4.1 Background Data Collection and Review Otak personnel will review available data and information and perform a field assessment to document existing geomorphic conditions and collect field measurements at the road crossing, in the immediate area upstream and downstream of the crossing. A suitable reference reach is not anticipated at the site due to the modified channel conditions. Otak will collect bankfull width measurements. Due to tidal influence and the tide gate at the River, the natural conditions tidal prism, and tidal channel development width will be considered when recommending a channel width. Prior to the site geomorphic field assessment (Task 3.4.2), Otak personnel will compile and review available data and background information applicable to the crossing site. This may include information such as historical aerial photographs, Government Land Office (GLO) maps, LiDAR imaging, surficial geology, FEMA flood maps, DNR hydrography information, topographic survey, and soils information. 3.4.2 Geomorphic Field Assessment A geomorphic field assessment will be conducted by Otak personnel. This assessment includes qualitative and/or quantitative evaluations of: bed material (type), particle size distribution (pebble counts), sediment transport setting, channel morphology, large woody material (LWM) occurrence, channel migration potential, riparian conditions, bankfull widths, beaver activity and man-made channel alterations/constraints and hydraulic controls. In addition, the reference reach will be field located, if applicable. Conditions will be evaluated upstream and downstream of the crossing, and within the reference reach. This field data will be used to inform the: • Bed material characteristics • Channel geometry dimensions and bed slope • Channel morphology • Reach -scale channel processes including sediment sources, deposition and erosion • Relative abundance of large and small woody material and their effects on channel stability and planform The field conditions and assessment will be summarized in the Geomorphic Assessment Memorandum (Task 3.4.4). 3.4.3 Bankfull Width Memorandum Otak will collect up to ten bankfull width (BFW) measurements within the project site during the geomorphic field assessment. The BFWs will be flagged in the field for subsequent location and measurement confirmation with Otak — Scope of Work 126 the agencies and Tribes. Upon completion of the field BFW collections, a draft memorandum will be prepared summarizing the BFW locations and field measurements. This memorandum will serve as the basis for the BFW site concurrence meeting and will be provided to the agencies and Tribes prior to the site visit. Otak will facilitate the on-site meeting with the agencies and Tribes (See Task 9.2). Review and agreement of BFWs will occur during this on-site meeting. The BFW agreed upon by the agencies and Tribes during the on-site field concurrence meeting will be presented in the final BFW memorandum and incorporated into the fish passage and habitat enhancement design. 3.4.4 Geomorphic Assessment Memorandum Otak will prepare a draft geomorphic assessment memorandum. This memorandum will summarize the existing geomorphic conditions at the site, based on the background data review and field data collection. In addition, this memorandum will provide the geomorphic recommendations to support the structure design including recommended bed material sizing, channel dimensions and planform, bed slope and large woody material. The final BFW memorandum will be attached as an appendix to this memorandum.

Within the Gilliam Creek channel area outside of the roadways, east of 66th Ave S and north of Tukwila Parkway and south of 1-405, Otak will review and utilize recent WSDOT electronic survey data and incorporate into the project basemap. We assume that the WSDOT data will be adequate for topography within the channel area described above and will not require supplemental survey shots by Otak. If the WSDOT files are not suitable for full topography within the Gilliam Creek channel area described above, the City will be notified of additional work required for full development of survey and basemap preparation within this area. Otak — Scope of Work 128 Wetland and ordinary high water flags placed by Otak in Task 3 will be surveyed. The topographic survey requirements include the following: ■ Vertical Datum: NAVD 88 ■ Horizontal Datum: State Plane Coordinates (Washington North Zone, NAD 83/91 adjustment) ■ Contours at a maximum interval of 1' ■ TIN surface ■ Road centerline alignment ■ Surface features: ▪ Ditch centerline ▪ Top/Toe of slopes ▪ Channel thalweg ▪ Top of bank Toe of bank ▪ Culvert invert elevations ▪ Catch basins with pipe inverts and diameters ▪ Location of all utilities and junction boxes in the project area ▪ Utility poles ▪ Edge of asphalt ▪ Edge of gravel ▪ Edge of concrete ▪ Road centerline ▪ Road striping ▪ Vegetation including trees, shrubs, and planters. ▪ Rockeries and retaining walls ▪ Fences ▪ Driveways ▪ Mailboxes ▪ Signs Mapping shall be consistent with City of Tukwila Infrastructure Design and Construction standards. 4.2 Right-of-way Survey Otak will prepare a right-of-way survey file based on property records review and field monuments. Property lines for those properties within the vicinity of the project will be researched. The Record of Survey and a lot closure report documenting all dimensions shown on the survey will be submitted to the City for review prior to recording. The following Items are required on the Survey: ■ Found Monuments-Section/Plat/Road ■ Descriptions of monuments ■ Monuments looked for but not found ■ Section subdivision if applicable ■ Existing right-of-way centerline ■ Existing right-of-way lines ■ Outline and deed number for existing right-of-way deeds ■ Survey note stating the history that established the right-of-way ■ References ■ Road name Otak — Scope of Work 129 ■ Road log number ■ Right-of-way width ■ Parcel lines of adjoining parcels (based on King County tax parcel lines unless otherwise noted) ■ Name and auditor's file number of adjoining plats ■ Parcel number of adjoining platted lots TASK 4 DELIVERABLES ■ Topographic Base Map (Scale 1" = 20 feet) with one -foot contour intervals (AutoCAD DWG file format) ■ Existing Right-of-way CAD file (AutoCAD file format) TASK 4 ASSUMPTIONS ■ The extents of topographic survey and mapping for the stream and adjacent infrastructure are shown on Attachment A.

The extents also include the southeast corner of the intersection of 66th Ave S. and Andover Park E and a portion of the parking lot on private property at 90 Andover Park E (Holiday Inn Express Hotel). ■ The City will obtain right -of -entry for the parcels for the area of survey. 5.0 Hydrology and Hydraulics 5.1 Hydrologic Analyses Otak will review the hydrology in the existing HSPF (Hydrologic Simulation Program Fortran) model provided by the City for Gilliam Creek at the project site location. It is assumed that the existing model includes all inputs needed for modeling the proposed stream system including precipitation, sub -catchment areas, and land use associated with the existing conditions. Otak will import the HSPF model into the Western Washington Hydrologic Model (WWHM2012) to produce a continuous time series of runoff data from the drainage basin. The continuous time series of runoff and associated peak rates will become the hydrologic input for the hydraulic analyses to be performed. A climate resiliency calculation will be performed for the flow frequency results from the HSPF modeling effort in order to determine possible future flows for the study site. The WDFW Designing Climate Change -Resilient Culverts tool will be used to estimate the scaling factor to apply to the 100 -year return period flow. 5.2 Hydrologic Documentation Otak will prepare documentation for the hydrologic analysis that will be included in the Hydrologic and Hydraulic (H&H) memorandum. The final H&H memorandum shall be sealed by a Professional Engineer licensed in the State of Washington. The hydrologic documentation will follow the following outline: Y Annual peak flow analysis for return periods ranging from the 2 -year to the 500 -year. Y Seasonal peak flow analysis for a two-month (July 1 to August 31), and a three-month (July 1 to September 30) period for the purposes of determining construction bypass flows. Y Flow duration curves at select locations. Y Climate Resiliency calculation for the study site. Y Electronic files for: ■ Hydrologic models Otak — Scope of Work 130 • GIS files • Survey files • Model schematics 5.3 Hydraulic Modeling 5.3.1 Alternatives Analysis Modeling A previous hydraulic analysis was conducted by others to evaluate fish passage performance of Conceptual Option 1 (Retrofit Flapgate in-place) The analysis was run utilizing the one-dimensional HEC -RAS hydraulic model for a 13 -year period with observed river and simulated local inflow. A statistical analysis was performed during critical fish passage durations to account for interaction of Gilliam Creek and the Green River. Otak will review the existing one-dimensional HEC -RAS model for the existing and proposed conditions from conceptual design, provided by the City. It is assumed that the statistical analysis to determine critical flow conditions for fish passage assessment will not be available. Otak will perform a statistical analysis of the time series data from the NHC hydraulic analysis to develop the joint probability of flows in Gilliam Creek and stages on the Green River. This will provide a range of plausible flow scenarios for the hydraulic analysis of Riverton Creek at the confluence. Otak will develop a proposed conditions model for an additional two proposed conceptual alternatives for comparison. The results of the models in regard to fish passage criteria will be presented in the Alternatives Analysis Matrix under Task 6. 5.3.2 Preferred Alternative Modeling Once the preferred alternative is selected and full site topographic survey has been completed for the upstream reach and the confluence with the Green River under Task 4.2, an existing conditions model will be developed using the Federal Highway Administration (FHWA) and U.S. Bureau of Reclamation's SRH -2D software (2020). A proposed conditions model for the preferred alternative will also be developed in SRH -2D. Steady-state inflow boundary conditions will be used based on HSPF modeled peak flows or flow duration curves, and the models will be run over a long enough simulation time to establish steady-state hydraulic grade lines. Due to the influence of tidal conditions, downstream boundary conditions including a high tide and a low tide condition will be evaluated as a part of the hydraulic model. The evaluation will also include an estimated sea level rise downstream condition to provide an evaluation of resiliency for climate change. The evaluation of the hydraulic conditions from existing to proposed conditions will include the change in water surface elevations, depths, velocities, shear stresses, potential upstream and downstream impacts from improving conveyance. The proposed water surface elevations will be used to establish the minimum height for the culvert replacement based on freeboard and debris clearance. The velocity results will be used to inform the design about potential fish -passage conditions, stream channel stability, and wood structure placement for the stream improvements. A stable channel analysis will be performed following accepted methods in WDFW Water Crossing Design guidelines and habitat restoration guidelines. Using results from the hydraulic analysis, Otak will perform calculations to understand the vertical and lateral stability of the existing channel and how the stability might be affected by the proposed design. Incipient motion calculations will be performed to identify the range of flows over Otak — Scope of Work 131 which the bed material will be mobile. The reach -average stream power from the existing and proposed conditions hydraulic model results will be compared to understand potential areas of erosion or sediment deposition in the stream channel post -project. The results of the analysis will be used to evaluate the width of the crossing structure following guidance in the WDFW WCDG's for fish -passable structures and Appendix D for Tidally Influenced Crossings. The WSDOT Log Metrics Calculator spreadsheet will be used to compare the proposed wood design to target wood volumes. Wood stability calculations will be performed using the USFS Computational Design Tool for Evaluating the Stability of Large Wood Structures, version 1.2. The preliminary wood stability calculations will be submitted with the 30% PS&E. Scour calculations will be performed at the culvert crossing for the design event (100 -year flow), and check event (500 -year flow), in accordance with the FHWA Hydraulic Engineering Circular (HEC) 18, Evaluating Scour at Bridges. 5.4 Hydraulic Documentation Otak will prepare hydraulic documentation that summarizes the findings and conclusions from the hydraulic analysis completed in Task 5.3. The hydraulic documentation will be included in the H&H memorandum described in Task 5.2. The memorandum will summarize the following topics: Y Hydrologic flow rates used in the hydraulic analyses Y Hydraulic conditions including water surface elevations, depths, and flow velocities under existing and proposed conditions Y Tidal conditions and boundary conditions from the influence of the tide gate system, and river Y Estimated sea level rise effects at the crossing structure Y Potential impacts to upstream and downstream properties, including changes to flows, velocities, and water surface elevations Y Channel stability calculations Y Potential areas of channel erosion, sediment deposition Y Calculated scour depths at the culvert crossing (100 -year, and 500 -year event) A draft and final H&H memorandum will be submitted to the City. The final H&H memorandum shall be sealed by a Professional Engineer licensed in the State of Washington. The final H&H memorandum will be included with the Project Design Report. TASK 5 DELIVERABLES Y Hydrologic and Hydraulic Memorandum (Draft and Final, electronic PDF file format) Y Hydrologic Model electronic files (WWHM or similar HSPF format), supporting GIS data files Y Hydraulic Model files (SRH -2D electronic file format) TASK 5 ASSUMPTIONS Y An F -Table will be developed at the drainage subbasin scale for routing flows within the stream channel. It is assumed that no other F -Tables will be required or developed for routing flows through detention structures upstream of the site. Y SRH -2D software will be used for development of the 30% hydraulic model. Otak — Scope of Work 132 Y The model domain will extend approximately 680' upstream from existing culvert inlet and 50' downstream of existing culvert outlet based on topographic survey data. Y Velocities and stream power will be used to perform a qualitative assessment of potential erosion and deposition under proposed conditions, and no quantitative sediment transport calculations will be performed. 6.0 Alternatives Analysis 6.1 Alternatives Development and Comparison Engineering estimates of anticipated construction costs will be prepared at the conceptual alternatives level. Estimates will be prepared using historical unit prices from similar projects, other current cost data, and recent City projects. Otak will develop up to three alternative concepts for the culvert replacement. Information collected from the desktop review and field assessment for targeted fish species, fish access, and potential habitat gain will be used to develop the potential alternatives for the stream crossings and habitat improvements. The proposed alternatives will follow guidelines from the WDFW Water Crossing Design Guidelines for fish -passage structures and Appendix D for Tidally Influenced Crossings where appropriate. The alternative concepts will include: • Description of each alternative • An Alternative matrix with evaluation criteria • A preliminary exhibit for each alternative, showing the stream horizontal alignment and vertical profile • Planning level cost estimate The evaluation criteria for the Alternative matrix will include fish passage and habitat, flood protection, structure type and size, potential utility relocation, construction considerations such as sequencing and temporary road bypass, opportunity for park and educational features, environmental impacts and permitting, and cost. A recommendation will be provided for the preferred alternative. A site visit during this task is estimated to verify field conditions related to the proposed solution elements. The site visit will be attended by up to five Otak staff. The hydraulic modeling to assess the effects of the solutions will be performed under Task 5.3.1. Otak will submit the comparison matrix and conceptual drawings to the City for review and will then hold a meeting at the City to review. Otak will provide a recommended alternative and through discussions with the City, a preferred alternative will be selected. The preferred alternative will be advanced to 30% Design after approval of a future Scope Amendment for final design. 6.2 Alternatives Cost Estimation Engineering estimates of anticipated construction costs will be prepared for each of the conceptual alternatives to a planning level. Estimates will be prepared using historical unit prices from similar projects, other current cost data, and recent City projects. TASK 6.0 DELIVERABLES • Conceptual plans and details for up to three alternatives (pdf) • Alternatives Comparison Matrix (pdf) • Planning Level Cost Est for each Alternative (pdf) Otak — Scope of Work 133 TASK 6.0 ASSUMPTIONS • Alternatives are required to be in compliance with the 2021 King County Surface Water Design Manual as adopted by the City of Tukwila. • Alternatives are required to be in compliance with the City of Tukwila Infrastructure Design and Construction Standards. • The three alternatives will be similar to preliminary work by others: o Option 1 Culvert only (structures: head wall, wing wall, assess impact to existing roadway wall) o Option 2 Road Culvert & Trail Bridge (structures: culvert head wall, culvert wing wall, assess impact to existing roadway wall, trail bridge Type Size & Location, TS&L) o Option 3 Road Bridge & Trail Bridge (structures: assess impact to existing roadway wall, road bridge TS&L). Assumes Trail Bridge TS&L from Option 2 mostly, if not completely, applicable. • If the Alternatives vary significantly from the conceptual options, by others, such as moving the levee back, a request will be made for authorization of management reserve funds to increase the Alternatives Analysis scope. 7.0 Geotechnical Services (Landau Associates, Inc.) 7.1 Phase 1 Geotechnical Investigation The geotechnical subconsultant Scope of Services is included in Attachment B. 8.0 Utility Coordination 8.1 Franchise Utility Coordination Otak will request as -built drawings and use data collected from the utility locates and topographic survey to verify the location of existing facilities. Otak will prepare a spreadsheet/matrix summarizing utility conflict locations and actions to be taken. Permit requirements for each location will be included in the matrix. This document will be updated whenever new information becomes available to assure that all utility coordination activities are tracked. Otak will also prepare a Comprehensive Utility Coordination Plan to show all existing and proposed utilities within the Corridor. Otak will begin communications with franchise utility companies (power, gas, telecommunications, water and sewer, etc.) following the selection of a preferred concept alternative by the City, to verify locations of existing facilities and to discuss any potential relocation requirements, cost, schedule and recommendations on location of new facilities. It is anticipated that up to three (3) utility coordination meetings will occur with franchise or City utilities that are determined to have conflicts or require relocation. TASK 8.1 DELIVERABLES ■ Utility Coordination Plan ■ Utility Coordination Tracking Matrix TASK 8.1 ASSUMPTIONS ■ Design of relocated utilities will be at franchise utility's expense and is not included in this scope. ■ Potholing of utilities to verify the underground location is not included in this scope but is recommended to be performed after 30% design. Otak — Scope of Work 134 9.0 Stakeholder Engagement 9.1 Stakeholder Engagement Plan Otak will develop a draft strategy at the outset of the project that includes the purpose and objectives to be achieved by the engagement, the entities to be engaged and informed during the project, activities and a timeline for engagement that aligns with the project schedule and key milestones, and specific responsibilities for engagement. The engagement plan will follow the "Informed Consent" model for community engagement. The community and stakeholder engagement lead and project manager will meet with City of Tukwila staff to review and discuss the strategy. After beginning the alternatives analysis under Task 6.0 and identifying the potential extent of improvements, Otak will then finalize the strategy based on input from City staff. This scope assumes a total of two (2) one and a half-hour online meetings between the City and Otak attended by two (2) Otak staff. The purpose of these meetings will be to discuss Otak's initial recommendations and key stakeholder issues that will guide the design. 9.2 Agency and Stakeholder Coordination At the City's request, Otak will support the City in coordination with agencies, tribal representatives, and stakeholders to address project designs and respond to comments. Otak will review and provide available information from previous data collected at the site to as requested. As part of this task, Otak will participate in an on-site meeting with representatives from the City of Tukwila, WDFW, Tribal representatives, and Otak to review the project goals, components, and habitat restoration benefits, and perform bankfull width measurements. Otak will coordinate with the City, WDFW and the Tribes to identify any potential reference reaches or appropriate bankfull width measurement locations. Otak will prepare memoranda to document site meeting notes. Otak will prepare email correspondence and memoranda to respond to comments received from the Tribes and agencies. As the level of effort for comment responses and coordination cannot be quantified at this time, a total level of effort of 40 hours of staff time is assumed for this scope task. Otak will attend up to four meetings with the WSDOT Design team working on Gilliam Creek Crossing Improvements upstream.

(Landau) is pleased to submit this proposal for preliminary geotechnical engineering services in support of the Gilliam Creek Fish Passage Improvements project in Tukwila, Washington. This proposal has been prepared with information provided by Otak, Inc. (project civil engineer). Project Understanding The City of Tukwila (City, project owner) proposes to improve fish passage along the lower reach of Gilliam Creek, where the creek runs parallel to Interstate 405 (site). At the site, the creek flows through a 108 -inch -diameter culvert beneath 66th Avenue South and the Green River Trail before converging with the Green River. Immediately upstream of this confluence, the culvert is fitted with a top -hinge flap gate with wing walls and a concrete splash pad. These features have been identified as barriers to fish passage. The design team has been asked to evaluate the following options for improving fish passage: • Option 1. Retrofit the flap gate and replace the splash pad with a roughened channel. The culvert beneath 66th Avenue South and the Green River Trail would remain in place. • Option 2. Daylight Gilliam Creek beneath the Green River Trail. The culvert beneath 66th Avenue South would be shortened; a bridge would be added; and the flap gate would be replaced. • Option 3. Abandon the existing Gilliam Creek culvert and replace with a daylighted reach beneath 66th Avenue South. The downstream portion of the creek would be moved to an expanded habitat and refuge area on the west bank of the Green River. Proposed Scope of Services Landau proposes to assess subsurface soil and groundwater conditions at the site. Findings will be used to select a preferred design option. Landau's proposed scope of services includes the following tasks. 155 NE 100th St, Ste 302 • Seattle, WA 98125 • 206.631.8680 • www.landauinc.com 138 Gilliam Creek Fish Passage Improvements Landau Associates Phase 1. Geotechnical Desktop Study Landau will review existing geologic and geotechnical information for the site and the surrounding area. Possible resources include data collected during previous subsurface investigations by others, geologic and topographic maps, and as -built drawings of area structures and roadways. Phase 1 findings will be summarized in an email. Phase 2. Preliminary Geotechnical Engineering Services Following completion of Phase 1, geotechnical findings will be reviewed at a charter meeting, and the options for fish passage improvement will be updated. During Phase 2, Landau will complete a geotechnical field investigation, laboratory testing, and preliminary engineering analyses. Findings will be used by Otak to develop rough order of magnitude cost estimates for the design options. Field Investigation A ctivities Prior to beginning the field investigation, Landau will prepare a geotechnical exploration plan for Otak's review and approval. Landau will mark exploration locations in the field and contact the Washington Utilities Coordinating Council's "One Call" locating service. Explorations will be located in the shoulder or within a travel lane of 66th Avenue South. As such, temporary lane closures will be required during fieldwork. Landau will prepare a traffic control plan and obtain a right-of-way use permit from the City. Landau will also subcontract traffic control services, including flaggers and warning signs. Initially, the hollow -stem auger drilling method will be used to advance two borings. When the borings encounter the groundwater table, drilling will be paused for up to 30 minutes to allow groundwater to equalize. The borings will then be advanced using the mud rotary drilling method. One boring will be advanced to a maximum depth of 80 feet (ft) below ground surface (bgs), and the other boring will be advanced to a maximum depth of 120 ft bgs. If bedrock is encountered, a core barrel will be used to extend the borings by as much as 10 ft, or to the maximum depths noted above. Landau also will advance as many as six hand auger borings upstream of the culvert. Landau personnel will monitor the borings, collect representative soil samples, and maintain detailed logs of the subsurface soil and groundwater conditions observed. The standard penetration test (SPT) procedure will be used to obtain soil samples at 21/2- or 5 -ft intervals. SPT samples will not be obtained from the interval at which coring is used to penetrate bedrock. Excess soil cuttings will be disposed of off site. Upon completion of drilling and sampling, the explorations will be decommissioned in accordance with the requirements in Washington May 4, 2022 2 139 Gilliam Creek Fish Passage Improvements Landau Associates Administrative Code Chapter 173-160. The pavement at each exploration location will be patched with fast -setting concrete. Geotechnical Laboratory Testing Soil samples obtained from the borings will be transported to Landau's geotechnical laboratory for further examination and testing. Landau anticipates that its laboratory testing program will include 12 index tests (grain size analyses or Atterberg limits determinations) and 6 moisture content determinations. Soil samples will be retained for 30 days following submittal of the final geotechnical engineering report. Samples will then be disposed of, unless other arrangements are made. Preliminary Geotechnical Engineering and Reporting The results of Landau's field investigation, laboratory testing, and engineering analyses will be summarized in a preliminary geotechnical report. The report will also include: • a site plan showing the locations of the field explorations. • summary boring logs and the results of laboratory testing. • a general description of site geology. • a discussion of near -surface soil and groundwater conditions observed at the site. • recommended seismic design parameters that accord with the American Association of State Highway and Transportation Officials' 2020 LRFD (Load and Resistance Factor Design) Bridge Design Specifications. • a soil liquefaction assessment, including estimates of liquefaction -induced settlement at ground surface. • preliminary recommendations for foundation support of the replacement culvert, including bearing resistances at the service, strength, and extreme limit states; axial and uplift capacities for deep foundations; estimated downdrag loads on deep foundation elements; and recommended L -pile input parameters, as applicable. • recommendations regarding static and dynamic lateral earth pressures on buried walls, including estimated lateral spreading loads on culvert wing walls, if applicable. • recommendations for final design services. Landau will prepare a draft report for the design team's review and comment. Upon receipt, comments will be addressed, and Landau will issue a final report, signed and sealed by the project engineer. Assumptions Landau made the following assumptions when preparing this scope of services and cost estimate: • Otak will provide Landau with a project base map in AutoCAD° format. • Temporary lane closures will be required during fieldwork. May 4, 2022 3 140 Gilliam Creek Fish Passage Improvements Landau Associates • The City will issue a right-of-way use permit at no cost to Landau. • The asphalt concrete pavement at the proposed exploration locations is not underlain by Portland cement concrete (i.e., no concrete coring will be required). • The City will allow Landau to patch pavement at the boring locations with fast -setting concrete. • Soil cuttings will be drummed and disposed of off site. • If required, permits pertaining to explorations in wetland areas or within stream buffers will be obtained by others at no cost to Landau. • All public and private utilities at the proposed exploration locations can be identified via a One -Call locate request. No vacuum excavation will be required. • Landau will not be responsible for damage to unmarked (or mismarked) utilities. • If required, right -of -entry permits will be obtained by others. • The hand auger borings can be completed in 10 hours, including travel time. • The field investigation can be completed during standard business hours (i.e., no weekend, holiday, or nighttime drilling will be required). • If necessary, Landau will evaluate as many as two deep foundation alternatives. • Additional geotechnical engineering services will be required to support final design of the proposed improvements. • Information regarding the infiltration characteristics of site soil is not needed, and infiltration testing and analyses are not included in this scope of services. • Chemical analysis will not be performed on soil samples collected from the explorations. Cost Estimate Services will be provided on a time -and -materials basis in accordance with the rates presented in Landau's 2022 Compensation Schedule (attached). Landau proposes to provide its services for a fee of $48,680, as detailed in Table 1 (attached). Landau will not exceed its budget without Otak's written authorization. Authorization To authorize Landau's services, please develop a subconsultant agreement, consistent with previous agreements between Otak and Landau.

A rate schedule will be provided on request. Subcontractor Services and Other Expenses Subcontractor billing and other project expenses incurred in the direct performance of authorized routine services will normally be charged at a rate of cost plus a twelve percent (12%) handling charge. A higher handling charge for technical subconsultants and for high-risk field operations may be negotiated on an individual project basis; similarly, a lower handling charge may be negotiated on projects requiring disproportionally high subconsultant involvement.

Interest of 1%2 percent per month (but not exceeding the maximum rate allowable by law) will be payable on any amounts not paid within 30 days.
