This data was used to identify utility depth near the proposed flood wall. This work was completed to support the 100% submittal. Task 9 Update CLOMR Submittals – This task is amended to update MT-2 forms to current standard, attend meetings with FEMA reviewers, electronically submit for a CLOMR and pay FEMA submittal fee for reimbursement by the City (included in Fee as an ODC). Task 10 - Respond to FEMA Comments – This task is amended to provide support during the FEMA review of the updated CLOMR submitted in Task 9, this includes comment responses and meetings with FEMA. Task 12 Contingency (Unforeseen Design to support FEMA CLOMR plus other support) – Amend this task to provide budget for unforeseen analysis and design associated with FEMA comments plus other support. If significant changes associated with FEMA comments occur a separate scope and fee will be submitted for City approval. The scope details are discussed below. Task 1 - Project Management and Meetings 2026 (Amended Task) Project management activities required for the completion of the Levee Improvement design and FEMA review (henceforth referred to as “design”) are described below. Subtask 1.1 – General Management (Amended Subtask) The CONSULTANT will continue typical project management activities which will involve team management, invoicing, and budget monitoring. Schedule Updates The CONSULTANT will prepare and submit an updated project schedule within two weeks of contract execution to the CITY and provide updated milestone dates monthly and a complete revised schedule (gantt chart style) no less than at the end of each quarter which details activities and clearly defines the following: 1. Critical path design elements and the CITY or CONSULTANT responsibility 2. CONSULTANT Task deliverables 3. Reasonable / forecasted timeline for FEMA CLOMR approval and acceptance Attach 2-3 April 2026 4. Other Agency permits and submittals 5. Anticipated construction bid, award, and start date The CONSULTANT will identify potential time frames associated with uncertainties connected with approvals of permits and other submittals by agencies. The CITY will provide input as requested during schedule updates regarding durations for review periods as needed. 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. Additional project management activities will involve team management, invoicing, and budget monitoring. Subtask 1.3 – Monthly 30 Minute Phone Call (Amended Subtask) Monthly 30-minute calls to discuss project progress will be held between the City of Renton PM and the Tetra Tech PM. Sixteen (16) 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 and report updates. Comments will be documented and saved in a QA/QC folder. Task 1 - Assumptions x Monthly progress meetings are 30-minute duration Phone Call. x Additional project design execution period is approximately 16 months (including FEMA review period). Task 1 - Deliverables x Notes and Actions Identified during 30-minute Phone Calls. x Schedule Updates. x Monthly progress reports x Monthly invoices TTask 8 – Improvement Design – 100% (Amended Task) Task 8 will be supplemented to address changes to the 100% design associated with the following items: Subtask 8.11 – Pothole and locate Boeing waterline This task involves the use of survey and utility locate professionals to identify and locate the Boeing water line crossing adjacent to the Senior Center. This data was used to identify utility depth near the proposed flood wall. Task 8 - Deliverables: 1. Surveyed location data located on Basemap 2. Data logs from locate services Attach 2-4 April 2026 TTask 9 – Update CLOMR Submittal (Amended Task) The body of the certification report summarizes the results of the technical analyses, and the report attachments include the supporting information. Under this task, the previous CLOMR submittal will be updated to include updated MT-2 forms required by FEMA. Subtask 9.7 – Update Report MT-2 Forms This task is being amended to update MT-2 forms and pay FEMA submittal fee for reimbursement by the City. The project team will update the MT-2 form to the most current version. Task 9 – Updated Appendices Include: x Updated MT-2 Forms x Update FEMA FEE submittal form Task 9 - Assumptions: x Other appendixes will not require update for this task. x A fee up to $10,000 is included to cover the Application Fee Task 9 - Deliverables: x Updated applicable reports: 1. EXHIBIT 1: MT-2 Forms 2. Updated Fee calculation Form 3. Pay FEMA Submittal fee (ODC) 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 9 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 Phase II 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: 1. Respond to FEMA Comments 2. Attend up to 3 Meetings with FEMA staff Task 10 - Deliverables: x Meeting Notes x Comment Responses Attach 2-5 April 2026 TTask 12 Contingency (FEMA comments and other Support) (Amended Task) This task is created to provide a pool of hours to cover unforeseen report revisions, design changes and other needs that come up as the project is executed. The funds under this task may be distributed to any of the Tetra Tech team members as determined appropriate by the City and Tetra Tech to perform the unforeseen work. If significant changes associated with FEMA comments occur, a separate scope and fee will be submitted for City approval. Task 12— Assumptions x Funds in this task will be allocated to the appropriate Tetra Tech team members when unforeseen work is identified. x When the need for conducting work covered by this task arises, Tetra Tech will prepare a scope of work and cost estimate and submit it to the City's Project Manager for approval. Task 12- Deliverables x To be determined and identified in the scope of work for each unforeseen work effort.
