BACKGROUND The S. 131st Place Drainage Improvement Project was established as a City CIP project in 2019. The primary goals of this project are to address local flooding of roadway and adjacent private properties and address upstream issues that contribute to flooding, water quality concerns and present fish barriers and habitat degradation. This contract will consist of two parts: 1) Part A will be to develop a permitted design for a fish-passable culvert beneath S. 131st Place and associated stream and/or roadway improvements that will improve stream flow, alleviate flooding, and eliminate barriers to fish migration; 2) Part B will entail an assessment and analysis of the Southgate Creek basin for the purpose of identifying future surface water improvement projects that will reduce downstream flooding, eliminate the need for regulated dredging activities, improve water quality, reduce undesirable erosion, and improve stream flow alignments and/or conditions to benefit fish passage and habitat. ANALYSIS A Request for Proposals (RFP) for engineering and design services was advertised in the Daily Journal of Commerce and Seattle Times. PACE Engineer’s proposal was reviewed and scored according to predefined criteria by a selection committee. PACE’s proposal scored high among committee members. The City has contracted with PACE Engineers for engineering and design services for numerous projects in the past with good results. Staff have had positive experience and continue to be very satisfied with PACE’s work. FISCAL IMPACT PACE has provided a cost estimate not to exceed $371,610.00 to perform engineering and design services for the S 131st Place Drainage Improvements Project. The project CIP design budget is $150,000.00 and the City has secured $120,083.00 in grant funding from the King County Flood Control District. If awarded, the remaining $101,527.00 could be funded by a pending grant of $300,000.00 or the Surface Water (412) utility fund.

CITY OF TUKWILA CONSULTANT ____________________________________ By: ___________________________________ Allan Ekberg, Mayor Printed Name: Ken Nilsen, PE Title: __Executive Vice President___________ Attest/Authenticated: Approved as to Form: _________________________ ______________________________________ City Clerk, Christy O’Flaherty Office of the City Attorney 103 August 10, 2022 City of Tukwila 6300 Southcenter Boulevard, Suite 200 Tukwila, WA 98188 Attn: Joshua Hopkins, Surface Water Project Manager Scope of Services Professional Civil Engineering Services South 131st Place Drainage Improvement Project Project Understanding The City of Tukwila would like to improve the Southgate Creek crossing of South 131st Street, along with a portion of the stream that is currently subject to routine flooding. The stream currently runs parallel to South 131st Street in a dug channel which accumulates sediments and requires periodic dredging. The existing culvert runs northwest beneath the roadway. The creek overtops South 131st Street during storm events flooding the street and a private access road belonging to NorMed. The project consists of two components to be worked on simultaneously. Part A is to develop a permitted bid-ready design for a fish-passable culvert beneath South 131st St and associated stream and/or roadway improvements that will improve stream flow, alleviate flooding, and eliminate barriers to fish migration. Part B is an assessment and analysis of the Southgate Creek basin for the purpose of determining hydrology and identifying future surface water improvement projects that will reduce downstream flooding and sedimentation. The hydrologic modeling and stormwater analysis portion of the Part B Basin Study will occur early in the project and will feed into the hydraulic modeling portion of Part A. Sequencing the basin stormwater modeling prior to the other portion of the basin study will allow for calibration of the model and develop a higher level of confidence in recreating the existing flow conditions in Southgate Creek. Scope of Work A detailed proposal consisting of fifteen (14) tasks follows. This proposal includes necessary civil, environmental, survey, structural, and geotechnical services through the design phase of this project. Construction administration and bid assistance is not included in this scope of work and can be reassessed at a later time based on the City’s needs. PACE will be the prime consultant for the entire Scope of Work and will oversee and administer all work on the project. PACE will complete all civil and survey in-house and will subcontract with GeoEngineers for geotechnical evaluations and permitting services. Task 1 –Project Management PACE will provide administration and coordination for both Part A and part B of this project. The following items are included in this task: 104 South 131st Place Drainage Improvement Project Scope of Work Page 2 1. Regular biweekly coordination and update meetings will be held with the City via Teams. Major design review meetings can be held in-person or remotely as required. The following major review meetings are anticipated: a) Conceptual Alternatives Design Review b) 30% Design Development Review c) 60% Design Development Review d) 90% Design Development Review 2. Review existing information provided by the City – as-builts, maintenance records, etc. 3. Coordinate with subconsultants. 4. In-house project administration, scheduling, and direction of design team staff. Task 2 – Part A: Topographic Survey PACE will provide a topographic stream and boundary survey showing all locatable utilities and surface conditions, environmental constraints, right-of-way, and other relevant items along Southgate Creek and at the South 131st Street crossing. Full stream and wetland survey will extend 300 feet downstream of the existing South 131st Street crossing and upstream along both Southgate Creek tributary channels to South 133rd Street. A channel centerline survey will extend to down to Southgate Creek’s confluence with the Duwamish River including the SR 599 crossing, a private access road crossing, and the outlet tide gate. The following items are included in this task: a) Develop survey limits. b) Research and confirm primary control points for use on the project. c) Establish horizontal and vertical control work points along the route. d) Survey the stream corridor locating surface improvements, types of material, and changes in elevation. e) All identifiable underground utilities will be surveyed along South 131st Street that will be impacted by the culver replacement. Utility locations will be based on surface indications, radio frequency locating and readily available maps from the service provider. f) The rights of way and adjoining properties will be calculated from record information and recovered monuments. g) The survey/base map will be prepared in AutoCAD® at a scale of 1” = 20’, showing the rights of way and lot lines, two-foot contours, and surveyed features. Other features from City GIS data (sensitive areas, setbacks, etc. will may be included to augment the survey). PACE will provide the City with AutoCAD® files, DEM, and pdf of the basemap. Task 3 – Part A: Conceptual Alternatives Design for Fish-Passable Crossing Based on a site assessment and the topographic survey, PACE will prepare up to three conceptual alternatives for the South 131st Street crossing and associated stream improvements for City review and comment. The alternatives will present options and address the following items, as well as any specific items requested by the City: • The need of property acquisition • The project extents and grading limits 105 South 131st Place Drainage Improvement Project Scope of Work Page 3 • Roadway impacts The following items are included in this task: a) Site visit to the South 131st Street crossing area to collect stream data b) Preliminary layouts for the three conceptual designs c) Pro/con list and high-level cost benefit for each alternative Task 4 – Part B: Basin Analysis and Stormwater Modelling This task consists of a desktop analysis of Southgate Creek basin to establish runoff volumes of individual sub-basin areas and existing flow paths leading to the South 131st St crossing. The task includes the following items: a) Review of all exiting stormwater infrastructure data in Southgate Creek basin including GIS data, as-builts, past watershed reports. b) Basin delineation using LiDAR and stormwater network data, the number and size of subbasins will depend on the density of the flow paths and pipe network. All significant flow paths will be captured in the stormwater model. c) Landcover and impervious area will be delineated form publicly available datasets and aerial imaging and combined with USDA NRCS soil data to calculate rainfall runoff modeling parameters. d) A continuous simulation MGSFlood stormwater model will use the SEATAC long-term rainfall record to calculate all statistical peak flow estimates (Q2 – Q500) e) Calibration of the MGSFlood will be based on the date of known storm events where flooding occurred ie. roadway overtopping. Task 5 – Part A: Hydraulic Design Report and Schematic Design (30 % design) After the preferred alternative and project extents are established, PACE will build an existing model & proposed condition hydraulic model and write up a basis of design report to establish how the project will mitigate flooding, meet fish passage requirements, and maintain structure resiliency. The Hydraulic Design Report will cover coordination with WSDOT on SR 599 plans and how the proposed project will function with future downstream improvements. Hydraulic modeling will be performed using the United States Bureau of Reclamation’s SRH-2D computer program, a FEMA approved two-dimensional (2D) hydraulic and sediment transport numerical model. Model results will inform multiple aspects of the crossing design including the structure size, streambed design, and scour. In conjunction with the report and modeling PACE will develop the 30% schematic design of the proposed crossing. The task includes the following components. a) Site assessment results b) Existing geomorphology c) Hydrology method and results d) Existing and proposed modeling and analysis e) WSDOT coordination f) Channel and crossing designs g) Streambed design h) Restoration components 106 South 131st Place Drainage Improvement Project Scope of Work Page 4 i) Scour analysis j) 30% design sheets Task 6 – Part A: Geotechnical Evaluation GeoEngineers will provide a geotechnical evaluation of the site. This evaluation will include up to two soil borings to depths of 40 feet below existing ground surface in the vicinity of proposed crossing structure and prepare a geotechnical design memorandum (see the attached Scope of Work from Geoengineers for more details on the geotechnical evaluation). Task 7 – Part A: Design Development Plans (60% Plans, Specifications and Estimates) Based on City comments on the 30% design, PACE will prepare Design Development Plans (60%) of the South 131st Street crossing and included stream improvements. We will also prepare an outline of the specifications and prepare an estimate of probable construction costs for City review and comment. This work includes: a) Design of the stream alignment b) Design of the proposed channel geometry c) Design of the roadway elevation and alignment d) Design of any large wood or other restoration features e) Outline of the proposed specifications using WSDOT format f) Prepare budget-level construction cost estimate Task 8 – Part A: Easement Preparation and Acquisition It is assumed that the project will require 3 permanent or temporary construction easements. PACE will prepare, coordinate with impacted property owners for signature and record all successfully secured easements. It is assumed that an appraisal is not required for this work and the City will secure any required Title Reports. If more than 3-easements are required, PACE will utilize the Management Reserve Fund as directed by the City. Task 9 – Part A: Permitting GeoEngineers and PACE will coordinate with the required permitting agencies and prepare all necessary permit applications. This task will be initiated as early as possible in the design process, based on the 60% design plans. The City will initiate coordination with permitting agencies earlier in the project to establish a relationship. The project is assumed to qualify for a streamlined permit process utilizing the Fish Habitat Enhancement Hydraulic Project Approval (FHE-HPA) process. GeoEngineers will lead the baseline critical areas assessment, environmental documentation, agency/tribal outreach and permit submittal processes. GeoEngineers and PACE will collaborate on permit application materials, as outlined in the attached Scope of Work from Geoengineers. Task 10 – Part A: Public Involvement PACE will assist the City with a public outreach to solicit comments on the design if required. This includes preparing materials for soliciting feedback from nearby and affected property owners. The task assumes preparation and attending one community meeting if deemed necessary. The City will be responsible for providing contact information for the businesses in the project vicinity. If a community meeting is held 107 South 131st Place Drainage Improvement Project Scope of Work Page 5 the City will be responsible for setting up the meeting time and location and notifying the businesses. PACE will organize any feedback received and prepare a written summary. Task 11 – Part B: Basin Planning Using data from the stormwater model and coordination with City staff PACE will identify problem areas or areas of opportunity for improvement within the Southgate Creek Basin. PACE will conduct a site visit to upstream areas to assess the potential and effectiveness of future surface water improvement projects outside of the restoration proposed in Part A. Improvements will aim to • Improve water quality • Reduce any flooding that may be identified • Reduce undesirable erosion • Improve fish passage and habitat Tasks Include: a) Developing a list of potential treatments or solutions b) Conduct a site visit to identified potential improvement locations c) Preparing a Tech Memo summarizing the basin stormwater modeling results as well as proposed improvements including a project description, sketch and preliminary cost estimate Task 12 – Part A: Construction Document Development (90% Plans, specifications and estimates) PACE will provide construction level documents based upon City comments from the 60% plan review. At this stage PACE will also develop complete project specifications utilizing contract documents and general provisions from past City projects. Any specific technical specifications will be created as needed. PACE anticipates the project will bid as one schedule and that the bid documents will be based on the most recent Washington State Department of Transportation “Standard Specifications for Road, Bridge and Municipal Construction”. It is assumed that the City’s review of these documents will be limited to two reviews and two set of revisions to get the documents “bid-ready”. Task 13 - QA (Quality Assurance) In order to assure that the final plans and specifications are complete, accurate and appropriate, PACE will conduct a quality assurance review of the documents prior to each submittal to the City. The review will consist of a complete sheet-by-sheet and contract document review to assure the City that the documents meet the standard level of care of our industry. Task 14 – Management Reserve Fund If directed by the City, PACE will provide services needed to assist the City with tasks related to this project that were not specifically addressed in this scope of work.

Our understanding of the requested services is based on email correspondence with you on July 18, 2022. We understand that our services are requested in support of Part A of the project, which includes replacement of the existing culvert conveying Southgate Creek under South 131st Place with a fish-passable crossing. At this time, our proposal does not address Part B of the project, which is a drainage study of the Southgate Creek basin. This proposal also does not address construction-phase support, which can be included in a future scope of work and/or contract amendment. SCOPE OF SERVICES Our proposed scope of services is split into two (2) tasks, one (1) addressing geotechnical engineering and the other environmental permitting. Task numbering follows the prime scope provided to GeoEngineers. Task 6. Geotechnical Engineering The purpose of our geotechnical services to review available information and explore subsurface conditions as a basis for developing geotechnical recommendations for the proposed Southgate Creek culvert crossing. 110 Pace Engineers, Inc. | August 5, 2022 Page 2 File No. 0259-061-00 Subtask 6.1 – Field Explorations and Laboratory Testing ■ Review readily available published geologic data and our relevant in-house files for existing information on subsurface conditions in the project vicinity. ■ Apply for and secure a Right-of-Way (ROW) Use Permit from the City of Tukwila (City) for the work to be completed along South 131st Place. Coordinate driller and traffic control subcontractors. ■ Visit the project site to mark out the preliminary exploration locations and contact the Washington State Utility Notification Center, as required by Washington State law. GeoEngineers, Inc. (GeoEngineers) will not be liable for damage to underground utilities that are not marked during the utility locating process. ■ Explore subsurface conditions by advancing up to two soil borings to depths of 40 feet below existing ground surface (for a total drill footage of 80 feet) using subcontracted equipment and operators. Our field representative will continuously monitor the drilling activities, maintain a log of subsurface conditions and collect representative soil samples at 2.5- to 5-foot intervals. ■ Conduct geotechnical laboratory testing on selected soil samples. We anticipate laboratory testing will include particle-size gradation analyses and moisture content determinations. Subtask 6.2 – Provide Geotechnical Design Recommendations ■ Provide a discussion of soil and groundwater conditions encountered in our explorations. ■ Provide the Seismic Site Class in accordance with the 2020 American Association of State Highway and Transportation Officials Load and Resistance Factor Design Bridge Design Specifications (AASHTO LRFD) criteria and discuss our opinion on the potential for surface rupture, liquefaction and lateral spreading at the site. Based on our experience with similar projects, we have limited the scope of our liquefaction analysis to simplified empirical methods addressing only the depths explored; advanced liquefaction analysis methods (such as effective stress analysis or numerical modeling) are not included in our scope at this time. If simplified analysis methods indicate a liquefaction risk that may cause significant damage to the structure, it may be appropriate to perform a more detailed evaluation at a later date. ■ Provide recommendations for site preparation and earthwork. We will discuss temporary erosion and sedimentation controls, temporary and permanent slopes, estimated stripping and clearing depths, fill placement and compaction requirements, suitability of on-site material for use as structural fill, import fill requirements, wet weather considerations, groundwater handling and dewatering, and site drainage. ■ Provide design recommendations for shallow foundations for culvert support in accordance with AASHTO LRFD guidelines. We will provide bearing surface preparation recommendations, including over excavation and replacement, if necessary, minimum recommended size, bearing resistances, and passive soil pressures and friction for resisting lateral loads. ■ Provide recommended active, passive and at-rest lateral earth pressures for the culvert and associated wingwalls in accordance with AASHTO LRFD guidelines. We will also provide recommendations for seismic surcharge pressures, if needed, and drainage criteria. 111 Pace Engineers, Inc. | August 5, 2022 Page 3 File No. 0259-061-00 Subtask 6.3 – Geotechnical Design Report and Consultation ■ Prepare a written geotechnical report presenting our findings, conclusions and recommendations. Our report will include a project site plan showing approximate locations of explorations, summary exploration logs, laboratory test results and appropriate engineering figures. ■ Provide limited consultation after our report has been finalized. We envision this will include answering geotechnical-related design questions in the form of phone calls, emails and or online virtual meetings. We have budgeted up to three (3) hours for Associate and three (3) hours for Project Engineer for this task. Task 6 Deliverables ■ Draft and final geotechnical report Task 6 Assumptions and Exclusions Our budget estimate is based on the following assumptions and exclusions: ■ GeoEngineers will obtain a ROW use permit to complete borings in street. We have assumed the City will waive all ROW use fees. ■ Our budget estimate assumes that the exploration can be completed in one (1) day during typical work hours. ■ Our budget assumes that South 131st Place can be fully closed between Macadam Road South to the west and local business access to the east on the day of drilling. We have assumed a traffic control plan will be required. ■ Borings through asphalt will be patched with cement concrete, and an asphalt repair will not be required. ■ We have not included the installation of wells nor monitoring of groundwater levels through the wet season at this time. ■ Our scope and fee assumes that soil cuttings generated by the drilling will be removed by the drilling subcontractor, and that signs of soil or groundwater contamination are not observed. Task 9. Environmental Permitting Permitting will be a joint effort between PACE Engineers, Inc. (PACE) and GeoEngineers. GeoEngineers will lead the baseline critical areas assessment, environmental documentation, agency/tribal outreach and permit submittal processes. GeoEngineers and PACE will collaborate on permit application materials, as outlined below. As a fish passage improvement project that removes a manmade barrier, the project is anticipated to qualify for a streamlined permit process utilizing the Fish Habitat Enhancement Hydraulic Project Approval (FHE-HPA) process for state approval and a programmatic consultation for Restoration Actions in Washington State for Endangered Species Act (ESA) compliance necessitated by the federal permit nexus. The FHE-HPA approval process obviates the need to complete State Environmental Policy Act (SEPA) and local permitting separately, streamlining the timeline and documentation requirements. The programmatic 112 Pace Engineers, Inc. | August 5, 2022 Page 4 File No. 0259-061-00 ESA consultation process streamlines the documentation and approval timeline for ESA compliance. The scope of services outlined below is premised on the project qualifying for these streamlined processes. Subtask 9.1 – Critical Areas Assessment and Report The purpose of this task is to identify and document regulated aquatic areas, critical areas and other permitting considerations. ■ Complete a background review of available project-specific data and publicly available wetland, stream, wildlife and soil databases. ■ Complete a site reconnaissance to identify and delineate wetlands, stream ordinary high water mark (OHWM) and other species or habitats present at the site that are protected by federal, state or local regulations. ■ Mark wetlands (if any) and streams in the field with survey flagging for subsequent professional land survey and incorporation onto the project base map. ■ Submit draft and final critical areas report for use during environmental permitting of the project. Subtask 9.2 – Environmental Documentation and Permit Application Materials ■ Complete a Joint Aquatic Resources Permit Application (JARPA) form for submission to regulatory agencies. Drawings that accompany the permit application will be provided by PACE. ■ Prepare ESA consultation documentation in the form of a Biological Evaluation (BE) and/or Specific Project Information Form (SPIF), depending on agency requirements (U.S. Fish and Wildlife Service [USFWS] and National Marine Fisheries Service [NMFS]). ■ Develop a Cultural Resources Survey (CRS) Report for compliance with Section 106 of the National Historic Preservation Act. This survey and report will be subcontracted to a specialty provider. Subtask 9.3 – Permit Submittal and Coordination ■ JARPA Form and Drawings and Critical Areas Report will be submitted to Washington Department of Fish and Wildlife (WDFW) for FHE-HPA review. ■ JARPA Form and Drawings, Critical Areas Report, BE and/or SPIF, and CRS Report will be submitted to the US Army Corps of Engineers (USACE) to obtain a Nationwide Permit under their authority to administer Section 404 of the Clean Water Act; most Nationwide Permits also include approvals for Section 401 of the Clean Water Act and Coastal Zone Management Act (CZMA) Consistency. ■ Track permit submittal, review and approval schedule and progress during the permit review periods. ■ Coordinate with the USACE, Washington Department of Ecology, WDFW and federal ESA agencies during permit review periods and respond to questions and requests for more information from these agencies. ■ Participate in a meeting with the City planning department to review compliance with the substantive requirements of the Critical Areas Ordinance in lieu of permit submittal, which is not needed due to the FHE-HPA. 113 Pace Engineers, Inc. | August 5, 2022 Page 5 File No. 0259-061-00 Subtask 9.4 – Design Coordination, Management and Support ■ Provide consultation to other members of the design team during design development addressing permit restrictions and requirements that may influence alternative designs or design details during advancement. ■ Support landscape design including identifying appropriate native planting palette for restoration of construction impacts within the riparian buffer. ■ Participate in team meetings over the course of the project duration. Task 9 Deliverables ■ Critical Areas Report ■ BE and/or SPIF ■ CRS Report ■ JARPA Application ■ Copies of each electronic permit application submittal ■ Permits received will be scanned and copies provided to the City Task 9 Assumptions and Exclusions Our budget estimate is based on the following assumptions and exclusions: ■ Professional Land Survey of the OHWM and/or wetland boundaries will be provided by PACE and is not included. ■ The project will qualify for a FHE-HPA; therefore, SEPA compliance and other local permits, including site development and/or clearing and grading, will be waived. ■ Project can be characterized as restoration and habitat enhancement and is, therefore, not anticipated to have adverse effects on regulated critical areas or other protected species or habitats; habitat mitigation planning and design is not anticipated to be needed. There are wetlands immediately adjacent to the site; as long as impacts to wetlands are temporary in nature and restored following construction (i.e., no permanent loss) and/or are minor in nature and limited to impacts from the replacement structure itself, we anticipate wetland mitigation will not be required. If sediment removal is required within the wetland or other permanent impacts cannot be avoided or minimized, including alteration of flow/hydroperiod, a hydrology study and/or wetland mitigation may be required. The final decision will be made by regulatory agencies, potentially in consultation with tribal stakeholders. ■ We have included a contingency fee estimate to provide a wetland hydrology monitoring study and wetland mitigation planning/design in case wetland impacts require mitigation. The hydrology monitoring study includes planning and preparation, procurement of well materials, installation of up to four (4) shallow groundwater monitoring wells and pressure transducers, data download and management for one (1) year, data analysis and a study report. Wetland mitigation planning and design assumes that compensatory wetland mitigation can be achieved either on-site, through purchase of wetland mitigation bank credits or an in-lieu fee program, or on another City-owned property, but does not include identifying an off-site mitigation site. The wetland mitigation 114 Pace Engineers, Inc. | August 5, 2022 Page 6 File No. 0259-061-00 conceptual design would be submitted with permit applications and would need to be incorporated into design drawings by PACE. ■ Drawings that accompany the permit application will be provided by PACE. ■ Design calculations (e.g., volumes, areas) needed for permit application materials will be provided by PACE. ■ The project will qualify for a Section 404 Nationwide Permit and neither an individual 401 Water Quality Certification nor a Construction Stormwater General will be needed from Ecology. ■ GeoEngineers will act as authorized agent for federal and state permit authorizations, such as those required from the USACE, WDFW and Washington State Department of Ecology (Ecology). ■ There is no state-owned aquatic land within the project footprint; an Aquatic Lands Lease will not be required from the Washington State Department of Natural Resources. ■ All deliverables will be provided as electronic files.
