The levee system is located between Lake Washington and the Williams Avenue South Bridge and is approximately 2.5 miles in length (1.25 miles on each side of the river). As of September 2024, the design is to the 100% level. During the review process, additional scope items were identified that will require revisions to the design for the project. The current scope involves the design and permitting of spot improvements at eight (8) sites along the project corridor. These sites are also located in areas of unique use including Renton Airport, Renton Parks and adjacent to the Cit s senior center. Some of these sites are further complicated by additional freeboard requirements due to their location near bridge crossings of the Cedar River. The additional freeboard needs impacted the level of effort needed to reach 100% design. Mitigation for the project involves landscaping areas disturbed by the improvements, plus enhanced riparian vegetation along the river corridor. The scope will be amended to add the following activities. Task 1 Project Management Extended project design schedule through March 2025 requires additional project management for PM activities including schedule and budget management, invoicing, and subconsultant coordination. Task 5 NEPA and SEPA Compliance - Minor Support to address any NEPA related comments Task 8 100% Draft & Final Design Revisions - Revisions to address additional plan and specification revisions to accommodate the level of detail necessary for each of the 8 design sites. More detail about these revisions are provided in the scope that follows. Task 10 Respond to FEMA Comments Respond to Minor FEMA comments. Task 11 Construction Bidding Support Provide engineering and design support during bidding of the project. C-2 December 2024 PHASE III Engineering Design, Permitting and Environmental Compliance, Scope of Work (Amendment 7) PHASE III Engineering Design Amendment 7 Summary The amendment covers additional scope and future services previously described in the project overview section. Design is anticipated to be complete in 2025, and bidding support is anticipated to be complete in 2026. The scope details are discussed below. Task 1 Project Management and Meetings (Amended Task) Project management activities required for the completion of the Levee Improvement design are described below. Subtask 1.1 General Management (Amended Subtask) The CONSULTANT will prepare and submit an updated project schedule to the CITY that details activities and clearly defines the critical path work elements. It will also include identification of potential the time frames associated with uncertainties connected with approvals of permits and other submittals by agencies. The CITY will provide direction on the durations for review periods to incorporate in the schedule. The schedule will be used to determine what tasks will go forward while submittal approvals are awaiting. Risks associated with going forward with certain tasks or subtasks prior to receipt of permit approval will also be identified and discussed to help inform scheduling decisions. The schedule will be updated monthly or as needed. Additional project management activities will involve, team management, invoicing, and budget monitoring. Subtask 1.2 Coordination Meetings (Amended Subtask) Three additional coordination meetings with the client will be held during Phase III. Each will be a 1- hour via Teams meeting. The first meeting will occur after submittal of updated Draft 100% PS&E. Up to five staff from the consultant team may attend each meeting: the PM, the lead Geotechnical Engineer, the lead Hydraulic Engineer, the lead Landscape Architect, and the Lead Environmental Scientist (permitting). Subtask 1.3 Monthly 30 Minute Phone Call (Amended Subtask) Monthly 30-minute calls to discuss project progress will be held between the Renton PM and the Tetra Tech PM. Items discussed will include scope, schedule, and Budget updates. Six (6) additional meetings are assumed for the duration of Phase III. Task leaders will attend those meetings when there are specific issues that need to be discussed in detail for their task. Prior to these meetings, internal staff progress and coordination meetings will be conducted. Subtask 1.5 QA/QC (Amended Subtask) The Project team will coordinate and perform QA/QC on the updated deliverables. Comments will be documented and saved in a QA/QC folder. C-3 December 2024 Assumptions Coordination meetings are 1-hour duration. Monthly progress meetings are a 30-minute duration Phone Call. Additional project design execution period is approximately 6 months (including FEMA and ESA review periods). Support during construction is not part of this scope. Deliverables Notes actions and comments identified during coordination meetings with the City of Renton. Notes and Actions Identified during 30-minute Phone Calls. Monthly Schedule Updates. Monthly progress reports Monthly invoices Task 5 ESA Compliance (Amended Task) Subtask 5.3 Endangered Species Act Coordination (Amended Subtask) Provide additional support related to ESA concurrence, NEPA completion by USACE. Task 8 100% Design (Amended Task) Task 8 will be supplemented to address changes to the design associated with the following items: Subtask 8.9 Draft 100% Civil Design (Amended Subtask) Additional Civil engineering design effort to incorporate comments from the 75%/90% design level plans and additional details. This effort will consist of the following items: Additional Civil Engineering effort to complete design of the eight (8) disturbed areas associated with flood improvement features. This includes comments not incorporated or requiring further clarification. The separate locations, increased freeboard requirements near bridges, and unique access needs outside the traditional public right of way create additional complexity for each location. Subtask 8.10 Final 100% Civil & Landscape Design (Amended Subtask) Civil engineering design will be updated to incorporate comments from the Draft 100% design level plans and additional details, plus updates in plans and specs due to USACE reviews. This effort will consist of the following items with an effort not to exceed 247 hrs.: Incorporate City comments and prepare Final bid documents. This effort is assumed to take up to 247 Hrs.

Deliverables Draft and Final 100% Plans in PDF and AutoCAD formats Draft and Final 100% Specifications. C-4 December 2024 Draft and Final 100% Cost Estimate. Task 10 Respond to FEMA Comments (Amended Task) This task involves responding to FEMA comments including coordination with FEMA on the CLOMR submitted under Task 4 of this Scope of Work. After the previous Phase II April 2018 CLOMR submittal, there was extensive coordination with FEMA. However, for resubmittal of the CLOMR in Phase III, it is anticipated that the level of coordination with FEMA will be reduced from Phase II. Based on input from FEMA during the previous CLOMR submittal process, the only remaining issue to resolve is compliance with environmental regulations, in particular, the Endangered Species Act. However, FEMA would not commit that all the documents would not go through the complete review process which could result in new questions and issues to resolve that were not brought up during the previous CLOMR submittal. Therefore, a reserve pool of hours has been established to address potential comments. This task includes the following work items: Review FEMA comments and participate in a phone call meeting with City staff to discuss approach to addressing the comments. Appropriate staff member from Tetra Tech and GeoEngineers and will participate in this phone call meeting. The consultant team will provide a brief letter to the City that outlines the approach to addressing the comments and the expected level of effort necessary to address the comments. If necessary, Tetra Tech and GeoEngineers will participate in a phone call meeting with the FEMA reviewers and/or FEMA regional technical representative present and coordinate our approach to addressing the comments on the CLOMR prepared in Task 4 of this scope. The overall purpose of the call would be to develop an understanding between the consultant team and FEMA on what is needed and will be provided to minimize the need for time consuming back and forth submittals. The consultant team will address the comments in a letter to FEMA. If additional information is required, it will be attached to the letter. It is assumed that CLOMR will not be revised and resubmitted (CLOMR submittal is covered in Task 4). Assumptions: One round of comments will be all that is necessary to satisfy FEMA . There will only need to be one call with FEMA to go over the comments and the consultant refresh FEMA on the previous submittal (April 2018). Potential team participants are the Project Manager, Lead Hydraulic Engineer, Lead Geotechnical Engineer, and Lead Environmental Scientist. Deliverables: Memo to the City summarizing the discussion with FEMA on the response to CLOMR comments including the proposed approach to responding to the comments and identification of any materials to be submitted with the response letter. attachments if necessary. C-5 December 2024 Task 11 Construction Bidding Support (Amended Task) Construction bidding support will be provided to select a contractor to perform construction of the final improvement plans. This will consist of attending a preproposal meeting and assisting answering bidding related questions as requested by the City. Deliverables: Response to bidders, as requested.
