CITY OF RENTON By:_____________________________ CONSULTANT By:____________________________ Armondo Pavone Mayor Diana Walker Division General Manager _____________________________ Date _____________________________ Date Attest _____________________________ Jason A. Seth City Clerk Approved as to Legal Form By: __________________________ Alex Tuttle Senior Assistant City Attorney Contract Template Updated 5/21/2021 OOTCA contract no. 3200 2/5/2025 Approved by Alex Tuttle via email 1/7/2025 Mott MacDonald Restricted City of Renton Seaplane Base (ii) Maintenance Dredging A&E Professional Services Scope of Work 1 Introduction This scope of work outlines the work, budget, and schedule for Mott MacDonald to provide coastal and dredging design, and sediment sampling services for the City of Renton Municipal Airport (Airport) Will Rogers- Wiley Post Memorial Seaplane Base project. The work will provide refinement of preferred alternatives, preliminary engineering design and regulatory permitting support services, and final design for two concurrent Architecture and Engineering (A&E) Professional Services packages: i)Seaplane ramp and dock design, and ii)Maintenance dredging design. The scope document outlines the scope, assumptions, and fee for the Maintenance Dredging A&E Professional Services package. 2 Project Understanding design and construction experience at the seaplane base, prior phases of alternatives development, and recent correspondence with the Airport. Following seaplane ramp construction in the early 1970 -term sediment deposition, flooding events, and changes of intended use have impacted the safe use of the existing seaplane basin. Recent sedimentation and debris accumulation within the seaplane base basin and associated infrastructure impacts have been influenced by a recent Federal Emergency Management Agency (FEMA) designated flood event which deposited sediment and woody debris within the Cedar River delta and adjacent seaplane base basin and boat house in February 2020. Accumulated sediments and debris within the basin have posed operational hazards for various operations in the vicinity of the Seaplane Base. This correlates to the following Objectives: A)Full dredging design for Wiley Post Memorial Seaplane Base Maintenance dredging is required to reestablish original depths and to facilitate safe access within the seaplane approach and departure zones of the seaplane base, as well as to facilitate safe access to floats, ramps and gangway infrastructure. It is understood that sedimentation beneath the existing docks is preventing the existing floating docks from full operation, often grounding out on the substrate and resulting in an uneven and potentially unsafe platform. Mott MacDonald will review condition reports (by others) to determine the most suitable approach to restore the floating docks back to full operation. This objective will be progressed through to Final Design. B)Dredging alternatives development for the Rowing Club and Delta It is understood that dredging beyond the seaplane base may be required at the adjacent delta and Rowing Club to restore the form, fit, function of the facilities. Less information is known about the Mott MacDonald City of Renton Seaplane Base Maintenance Dredging and Sediment Sampling Scope of Work 2 Maintenance Dredging and Sediment Sam cope of Work Mott MacDonald Restricted design criteria for the work that may be required at this stage, this scope task will be developed to alternatives development design only (10%). It is also understood that the Airport also wish to better understand their long-term strategy to deal with maintenance dredging for the seaplane base, from a benefit cost perspective. For example, the construction of a training wall to extend the mouth of the delta into Lake Washington may help to contain the flow of debris during storm events and may consequently reduce future dredging expenditure. Due to the environmental sensitivities, permitting of this task is expected to be highly challenging and may require a different time schedule and funding stream from the other tasks listed herein. As such, this element of works shall comprise data collection and a workshop with subject matter experts to discuss previously developed alternatives, new alternatives where necessary, developed to 10% design, and a budget allowance to produce a roadmap for potential further design work for the preferred alternative. Mott MacDonald has developed an approach to the work based upon previous project experience, specifically associated with evaluating and assessing alternatives for dredging and dredged material management. The scope of work provided herein is based upon an in-depth understanding of the project goals and objectives, previously developed reports, documentation, existing utilities infrastructure, physical and environmental site conditions, anticipated engineering analysis and engineering details typically required for obtaining environmental permits required for design and construction work at the project site. Actual project requirements may vary based on site specific conditions and comments/directives received during meetings and via early correspondence with regulatory agencies and project stakeholders. 3 Assumptions and Exclusions The following assumptions and exclusions apply to the scope of work outlined herein: Existing Data: Mott MacDonald will compile existing, readily available data available for use in conducting the work described herein, and existing elevation survey data collected during previous phases of work. The Airport shall provide Mott MacDonald with: As-built data for the bulkhead Existing condition assessments for ramp, bulkhead and pontoons New Data: Elevation survey: Existing data for the seaplane base and surrounds was collected in the spring and fall of 2020. Delta surveys are available from 2022. The collection of new in-water and/or upland elevation data is recommended to capture geomorphological change and has therefore been included within the cost estimate. This will be used to inform the evaluation and assessment of flood impacts on existing infrastructure and subsequent design phases. The cost estimate includes a survey of the delta; assuming the surveyor can walk on the delta. Upon review of existing data, Mott MacDonald will inform the Airport if the scope of new elevation survey can be reduced. Geotechnical Investigation. No geotechnical in water borings included. Condition Assessment: Mott MacDonald City of Renton Seaplane Base Maintenance Dredging and Sediment Sampling Scope of Work 3 Maintenance Dredging and Sediment Sam cope of Work Mott MacDonald Restricted Condition assessments of Airport Infrastructure is excluded from the scope of this dredging contract.

Optional Expanded Sediment Sampling: Delta: Assumes 2 days fieldwork required, with access by foot and vessel, subject to water level and a Health and Safety assessment. Rowing Club: Assumes two days fieldwork undertaken by vessel. Design Deliverables: Preliminary design deliverables of 8.5x11 JARPA format drawings and sections of technical narratives are assumed to be sufficient for the Airport to submit permit applications to the applicable regulatory agencies. It is assumed that two (2) JARPA application packages will be developed for this project: One (1) application package will be developed for in-water sediment sampling and chemical analysis for the Seaplane Base (Objective A), and One (1) for the Seaplane base dredging works (Objective A, described in Section 2 herein), inclusive of the dredging beneath the existing floating docks. If appropriate and instructed as contract variation, Objective B will also be included within the same application, although this variance from past applications may delay the approval process. No independent JARPA packages will be developed for Objective B described in Section 2 herein (Dredging alternatives development and preliminary design for the Rowing Club and Delta). Full size detailed drawings for grading and/or building permit approval will be developed during the final design phase. It is assumed that all comments on draft deliverables, including final design packages, will be returned to Mott MacDonald by the Airport within two weeks of the submittal. Comment response periods longer than two weeks may result in an extension to the project schedule. Regulatory support: Regulatory permitting support work scope is provided to assist with the development of application documents, attend pre-application meetings, and assist with submittal of permit applications. It is assumed that the Airport will act and will be the primary point of contact with regulatory agencies. Permit application development and submittal to be led by Widener & Associates in coordination with Mott MacDonald and the Airport. It is assumed that Widener & Associates will contract directly with the Airport for all permitting and regulatory support required for this project. Development of the sediment Sampling and Analysis Plan (SAP) and laboratory testing for chemical properties will be conducted by Mott MacDonald.
