The project reach is located between River Mile (RM) 5—6.5 on the Middle Hoh River between Highway 101 and Olympic National Park in western Jefferson County, Washington. The primary goals of the project are to increase spawning and rearing habitat for spring Chinook, steelhead, and coho while improving local community resiliency by decreasing risks associated with flooding and erosion. Work to be completed by the Contractor is divided into the following list of tasks and linked to specific project deliverables: Task 1: Existing Conditions Characterization Task 2: Existing Conditions Reach Hydrology & Hydraulics Task 3: Reach Geomorphology Task 4: Climate Change Impacts Task 5: Project Management & Coordination Task 1. Existing Conditions Characterization Contractor will collect and analyze information on current and past site conditions to inform development of conceptual restoration designs for the Lindner Complex Reach. The analysis approach supports reporting consistent with requirements in RCO SRFB Manual 18 (https://rco.wa.gov/carp-content/.iplaads/2019/05/SAL-Manuall8.pdf). The existing conditions assessment field work will be limited to the channel and floodplain area south of the Upper Hoh Road where access has been arranged. Contractor will work with the County and RCO to determine the extent to which a Cultural Resources desktop review of the project area and development of a work plan should be initiated as part of this task to ensure sufficient time for consultation with RCO and the affected Tribes on the extent and nature of cultural resources field investigations. The Existing Conditions Characterization task is divided into the following sub-tasks: Subtask 1.1. Riparian Forest and Floodplain Wetlands Condition Field Assessment Contractor will characterize riparian floodplain conditions within the project reach. The riparian forestry mapping in the project reach completed for the Resiliency Plan will be updated using the 2022 LiDAR and verified in the field for accuracy. Contractor will complete a desktop review of National Wetland Inventory, Jefferson County wetland inventory, and National Resource Conservation Service(MRCS) soils mapper to identify areas of hydric soils and mapped wetlands and waters of the U.S. to support the subsequent field assessment. It is anticipated that 3 days of fieldwork will be required to fully assess this reach. The field verification effort will focus on collecting existing conditions data on: • Riparian stand composition and condition • Floodplain vegetation communities • Extent and nature of wetlands proximate to the channel to determine extent of existing connectivity to key salmonid rearing habitats and opportunities for improved connectivity Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment A Page 1 of 6 • Indicators of the Ordinary High Water Mark (OHWM)to correlate with the existing conditions hydraulic modeling (Task 2) Subtask 1.2. Geomorphic Field Assessment Contractor will document and characterize active and impaired geomorphic processes in the reach, as well as record existing habitat protection and restoration opportunities. Data to be acquired to support the geomorphic assessment and deign include: • Active bank erosion • Significant local sediment inputs • Pebble counts sufficient to characterize mapped channels • Active deposition and/or incision • Bank protection • Field verification of relative elevation model (REM) • Design constraints Task Assumptions • County will coordinate permission to access private property needed for field surveys. • River flows will be sufficiently low as to not restrict access to perform field work safely. • Landowner meetings will not occur during field data visits. • Travel costs and field equipment use will be billed as expenses and are included in costs. • Additional topographic information will only be collected if deemed necessary at high- risk locations. Task Deliverables: • Existing conditions description chapter for assessment report and relevant figures and appendix. Task 2. Existing Conditions Reach Hydrology & Hydraulics Development of an existing conditions hydraulic model of the project reach will be a critical tool for understanding flow patterns during seasonal and flood levels, identifying restoration opportunities, characterizing the extent of floodplain and wetland connection currently. Subtask 2.1. Hydrology Hydrology for the hydraulic model will be developed by analyzing USGS gages (#12041200, #12041000) using Bulletin 17C guidelines (USGS 2018). Recurrence flows for the un-gaged tributaries will be estimated using regional regression equations developed by Mastin et. al. (2016). Tributaries less than 10 square miles of drainage area will not be included in the hydraulic model. Low flow discharge for the Hoh and tributaries will be estimated using methods outlined in Curran et. al. (2012). Subtask 2.2. Hydraulics Contractor will develop a 2-dimensional (2D) hydraulic model using the US Army Corps HEC- RAS program. The model will encompass the project reach and utilize 2022 bathymetric LiDAR Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment A Page 2 of 6 acquired by the Hoh Tribe as the primary source of topography for the model mesh. To ensure boundary conditions are not influencing results within the project reach,the 2D hydraulic model will be extended up to Spruce Canyon(near RM 25.5)and down to Schmidt Bar(near RM 19.5) where the valley naturally confines the channel. Risk based and geomorphically relevant flow simulations will be performed for the 1, 2, 10, 25, 50, and 100-yr recurrence floods. In addition, flows during Winter Steelhead and Spring Chinook Salmon spawning periods will be modeled under existing conditions, to assess existing velocity and depth conditions during this critical life history stage to evaluate habitat suitability. Proposed condition model iterations will consider the same parameters to understand proposed habitat lift at the as-built condition. This information will guide design of optimal ecological outcomes and offer a useful communication tool for community members and other key stakeholders by species during spawning times. The existing conditions 2-year flow output from the 2D hydraulic model will be compared to data collected in Task 1 relative to the Ordinary High-Water Mark(OHWM)to support delineation of that regulatory boundary (Task 10) and to characterize the extent to which floodplain surfaces, side channels, and associated wetlands are currently connected to flood flows. This data will be used in Task 10 to support the development of permit application materials and the demonstration and quantification of benefits to aquatic habitats, including wetlands. The development and results of the existing conditions 2D hydraulic model, flow recurrence calculations and estimates, and recent trends in peak flows will all be detailed in a chapter of the basis of design report, including an appendix of maps illustrating the model results. Development of all proposed conditions,model simulations used for design development and FEMA compliance are included in later tasks. Task Assumptions • Streamflow estimates will follow USGS Bulletin 17B/C guidelines for gaged sites and using regional values for skew and standard error.No additional field streamflow measurements or gaging instrumentation are needed. USGS StreamStats will be used where no stream gage information is available. • Models will not be calibrated to regulatory (e.g. FEMA FIS)models or existing benchmarks. Task Deliverables: • Reach Hydrology & Hydraulics chapter within assessment report, including relevant figures and map appendix. Task 3. Reach Geomorphology Contractor will document historic disturbances in the project reach that have impaired natural geomorphic process and broken the large wood cycle,resulting in a more dynamic and unstable system that lacks reliable instream and off-channel habitat for salmonids, and a river that regularly poses flooding and erosion risk to the community. Understanding the underlying mechanisms that continue to impair habitat availability and contribute to instability is critical to developing a restoration strategy that will put the system on a sustainable path to recovery. Historic air photos, maps, and existing geospatial data will be used to characterize how the channel and floodplain have evolved over time in the project reach. Channel migration rates will be Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment A Page 3 of 6 quantified over time, channel avulsions will be documented, and the influence of large wood and logjams in the reach on channel migration and avulsions will be described. Remaining patches of old growth forest in the floodplain, more resistant to erosion, will be delineated and erosion rates compared to areas with less mature vegetation. The unvegetated active channel will also be delineated on historic air photos to measure change in area over time. Pre-disturbance channel migration and avulsion rates, unvegetated active channel area, and the role of large wood and logjams will be compared with those measured in the disturbed project reach using a reference reach on the Queets River between RM 19 and 23 that has a similar drainage area as the Lindner Reach. The 2013/14 LiDAR of the project reach will be compared with the more recent 2022 LiDAR to quantify the magnitude and spatial distribution of changes between the two data sets. Peak flows occurring in the time period between LiDAR flights will be used to place the magnitude of changes in context with recent flood history. We will use the composite 2013/14 surface that includes the LiDAR data and channel bathymetry collected by Wild Fish Conservancy in 2014 to compare not only the overall changes to the surface,but also target changes specific to the channel thalweg over time. The data and methods used for the geomorphic assessment will be detailed, along with results and implications for the design, and will be included in a chapter in the basis of design report, including maps and figures as needed to illustrate the results. Task Assumptions • Only publicly available georeferenced photos, including those used for the Resiliency Plan, will be used in the geomorphic assessment,NSD will not georeference additional historical aerial photos that do not have spatial metadata. Task Deliverables: • Reach Geomorphology chapter within the assessment report, including relevant figures and appendices. Task 4. Stakeholder Engagement& Community Outreach At the start of the project Contractor will work with County to develop an Engagement and Outreach Plan, to detail the process and schedule by which the project will connect with landowners, communicate with the Hoh Tribe and other identified groups and the public, and solicit input for the entire project, including final design development. It is anticipated the Plan will include the following: • Making presentations and providing workshop or site visit materials at up to two watershed-level "Hoh River Resiliency" events (in person at various Hoh River, Forks, or project locations) with interested community members in the watershed in 2025 and/or 2026. • Convene and facilitate four meetings for a new ad hoc Lindner Reach Technical Advisory Group (online or hybrid)that includes representatives from relevant permit agencies, County, and local technical experts including the Hoh Tribe at key design milestones including: o Completion of existing conditions characterization, draft concept designs, ranking and selection Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment A Page 4 of 6 o Completion of 30% design o Completion of 60% design o Completion of 90%design • Present to Hoh Tribal Council, County leadership, City of Forks,user and/or economic groups (recreational boaters, guides, fishers, etc.), or other stakeholders (up to 10 in person meetings at various local locations.) • Meet individually up to a combined 40 times with the Hoh Tribe, individual landowners, local businesses, and/or specific user groups (in person—Hoh River or North Olympic Peninsula) With input from project partners, Contractor will support the County to organize, convene, and facilitate public meetings, and meetings with individual stakeholders and landowners. Task Assumptions: • County is responsible for scheduling and coordinating meetings and events except mutually agreed upon landowner meetings. Task Deliverables: • Engagement and Outreach Plan and Community Outreach and Engagement plan. • Total of 1 presentation with Hoh Tribal Council • Total of 1 presentation with landowners and agency representatives. Task 5. Project Management& Coordination Contractor will provide project management, coordination and support to the County for the duration of the project. Project management and coordination will be provided via brief 30-minute weekly (or 60-minute biweekly) check-in meetings with project management team, monthly invoices with project activities summarized, and regular correspondence between Contractor, project management team and County via email and phone to maintain open communication. Mike Ericsson, Contractor's project manager, and Ryan DeKnikker, Contractor's deputy project manager, will co-lead activities. Ryan will cover project scheduling, maintaining adherence to the scope of work,timelines, and due dates; Mike will coordinate with the County and within the Contractor team, and Tim Abbe will lead the team interaction with local stakeholders and subconsultants, with support from Ryan as a part of Task 5: Stakeholder Engagement and Community Outreach. Both Mike and Ryan will ensure adherence to data quality assurance and controls, with Tim Abbe leading the project QA/QC process. Ryan will work with Mike to produce summaries of work completed to accompany our monthly invoices for services completed. Task Assumptions • The duration of the project will be 9 months, from January 2024 to September 2024. Task Deliverables: • Monthly invoicing detailing work completed. • Regularly scheduled check-in meetings with Contractor and County (weekly or bi- weekly).

The analysis approach supports reporting consistent with requirements in RCO SRFB Manual 18 (https://rco.wa.govtwp content/uploads/2019/05/SAL-Manual/8.pdf). The existing conditions assessment field work will be limited to the channel and floodplain area where access has been arranged. The project team will work with the County to determine which information is most essential to the development of conceptual designs, versus data that is valuable but not essential. For example, Contractor will work with the County and RCO to determine the extent to which a Cultural Resources desktop review of the project area and development of a work plan should be initiated as part of this task to ensure sufficient time for consultation with RCO and the affected Tribes on the extent and nature of cultural resources field investigations.

The data and methods used for the geomorphic assessment will be detailed, along with results and implications for the design, and will be included in a chapter in the basis of design report, including maps and figures as needed to illustrate the results. Task Assumptions • Only publicly available georeferenced photos, including those used for the Resiliency Plan, will be used in the geomorphic assessment, NSD will not georeference additional historical aerial photos that do not have spatial metadata. Task Deliverables: • January 2025 -Reach Geomorphology chapter within the assessment report, including relevant figures and appendices. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 4 of 19 Task 4. Climate Change Contractor will utilize the river-scale findings from the Middle Hoh River Resiliency Plan (NSD 2022)to estimate the resiliency benefits of concept design alternatives under potential climate change conditions at the reach-scale. Any new climate model predictions that have been done since the Resiliency Plan will be incorporated into the assessment. At the watershed-scale, higher precipitation rates due to ongoing climate change effects will increase the magnitude of annual peak and average winter flows and contribute to increases in mass-wasting and sediment delivery to the river. Contractor will verify and apply these watershed-scale findings to the reach-scale to analyze the following: • The potential effects of increased sediment delivery on the project reach in terms of channel bed aggradation, flooding, and channel migration. • How increases in flow may expand flooding extent in the project reach and contribute to increases in channel migration rates. • Impacts on the potential extent and availability of off-channel habitat for salmonid species. I. Potential impacts of erosion and channel migration on mature riparian and floodplain forest. • Potential impacts to infrastructure and private property. • Climate change mitigation opportunities will be evaluated as a part of Task 6: Concept Design Development. • Recent channel changes, within the last 25-years, will be analyzed as a part of Task 3: Reach Geomorphology. • The effects of climate change on peak flows will be simulated for each concept design alternative and the preliminary design as a part of Task 6 and Task 7, respectively using flows predicted in Task 4. • The effects of climate change on ESA listed Bull Trout(S. Confluentes)who require cold, complex habitat to survive, and are therefore extremely sensitive to increasing temperatures. Task Deliverables: • January 2026 Climate Change chapter within the preliminary basis of design report, including relevant figures and appendices. Task 5. Stakeholder Engagement & Community Outreach The project Contractor will work with County to update the Engagement and Outreach Plan developed for the Lindner Reach,to detail the process and schedule by which the project will connect with landowners, communicate with the Hoh Tribe and other identified groups, and solicit input for the entire project, including final design development. It is anticipated the Plan will include the following: • Convene and facilitate four meetings for a new Fletcher-TNC Reach Technical Advisory Group (online or hybrid)that includes representatives from relevant permit agencies, County (including leadership), and local technical experts including the Hoh Tribe at key design milestones including: Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 5 of 19 o Completion of existing conditions characterization, concept designs, ranking and selection o Completion of 30% design o Completion of 60%design o Completion of 90%design • Present to Hoh Tribal Council, (up to 4 in person meetings online.) • Meet individually up to a combined 20 hours with the Hoh Tribe, landowners, and/or County representatives (online or in person—Hoh River or North Olympic Peninsula) With input from project partners, Contractor will support the County to organize, convene, and facilitate public meetings,technical meetings, and meetings with individual stakeholders and landowners. Contractor will contribute to and review Agency-led outreach products including a watershed newsletter. As feasible,the project will offer opportunities to involve local community, faculty, and students from the new Natural Resources Program at Peninsula College in Forks: https://pencol.edu/program/natural-resources. Task Assumptions: • County is responsible for scheduling and coordinating meetings and events except mutually agreed upon landowner meetings. Task Deliverables: • January 2026 Engagement and Outreach Plan and Community Outreach and Engagement chapter for preliminary basis of design report. • 4 TWG meetings (online/in person). • Total of 4 workshops with Hoh Tribal Council, Jefferson County Board of Commissioners and Forks City Council (online/in-person). • Up to 20 hours of meetings with landowners (Fletcher/TNC/DNR) and the public Task 6. Concept Design Development High-level concept designs were created for this reach as a part of the Middle Hoh Resiliency Action Plan. These concepts include actions to sustain side-channel habitat for salmonids, installation of engineered log jams (ELJs)to restore valuable salmonid habitat and limit large mass- wasting or avulsion events in the project reach. Contractor will re-evaluate these initial concept ideas within the context of a more-detailed existing conditions characterization(Tasks 1 -3), climate change impacts (Task 4), and up-to-date stakeholder and community input (Task 6). Following the completion of the Existing Conditions Characterization Tasks (Tasks 1 - 3), Contractor will work with the County to develop up to 3 conceptual design alternatives for the Fletcher-TNC Reach. The design team will collaborate with the County on development and evaluation of different design alternatives to achieve the project goals and objectives. The 2D hydraulic model developed in Task 3 will be updated to depict each alternative to determine possible side channel flow pathways and to identify flood hazards and range of ecological benefits to aquatic and floodplain wetland habitats. Large wood structures will be incorporated into the model mesh to investigate hydraulic influence. The benefits of each alternative will be compared, and the hydraulic models will be reviewed to analyze potential for floodplain wetland restoration and riparian community enhancement. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 6 of 19 Compliance with floodplain regulations will be an important consideration in evaluation of design alternatives. Evaluation criteria that may be considered include wetland restoration and aquatic habitat improvements, anticipated geomorphic response, construction feasibility, regulatory complexity and timeline, infrastructure impacts, and cost. A"no action alternative"will be included that compares the evaluation criteria for the proposed concept designs to existing conditions. Initial consultation with regulatory agencies during the conceptual design phase will be completed as part of Task 10 to clearly understand the implications and complexity of each alternative and to contrast with no action and road-first protections. Permit application preparation, including the cultural resources assessment and wetland delineation, will occur following the selection of the preferred alternative and advancement through the Preliminary Design phase (Task 7). Contractor will draft plan view maps of the design alternatives and describe project elements in relation to project goals and objectives as well as potential modification to existing habitats, land use and regulatory constraints. The design evaluation is anticipated to include discussion of the type, size, and proposed quantity of wood placements within the side channel and related ecological benefits, in addition to other design criteria. Contractor will document evaluation of design alternatives as part of the Conceptual Design Development chapter within the basis of design report, including recommendation of a preferred design alternative and submit the draft report to the County for review. County will provide review comments and guidance regarding decision on selecting a preferred alternative that will be advanced to a preliminary design stage in the next task. Contractor will revise the working draft of the Conceptual Design. The Development chapter will incorporate the County's review comments as part of the basis for selecting the preferred alternative. The revised draft will provide a deliverable that can be shared with the SRFB review panel and other stakeholders for additional review. The design and deliverables will meet the requirements presented in Manual 18: Salmon Recovery Grants. Task Assumptions • Reporting for conceptual designs will focus on treatment methods and screening criteria and will not be detailed site-specific design. • Detailed design will not occur at this phase of the project. • County will select a Preferred Design to move forward into Preliminary Design • County will provide one round of consolidated review and comment on draft deliverables. Comments and any subsequent design revisions will be incorporated during Preliminary Design(on all concept design deliverables). • Conceptual design sheets will be provided in 1 1x17 pdf format and will be limited to simple plan view representations of proposed actions under each alternative. • Up to three (3)proposed conditions alternatives will be considered. • Hydraulic modeling of design alternatives will utilize the same hydrology and model flows developed for Task 3. • Potential impacts to the FEMA approximate Zone A special flood hazard area(SFHA) will be considered during alternative development and analysis. • The project will not progress into preliminary design until the County selects a preferred alternative. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 7 of 19 • Contractor will not develop special provisions as part of the concept designs. • Cost estimates will be developed as rough order of magnitude estimates and will use rolled up cost line items that are anticipated to be refined in final design. Task Deliverables: • May 2025 Three concept design alternative drawings/plans, maps comparing changes in hydraulic conditions for each design alternative relative to existing condition,ranking matrix for concept design comparison • January 2026 Concept Design Development chapter within the preliminary basis of design report. Task 7. Preliminary Design Development The preliminary design plans are intended to be permit-ready plans for use in initiating project permitting discussions with the County, Tribal and federal, state, and local regulatory agencies. The development of the 60%plans will include the following subtasks: • Draft (30%) and Final (60%) Preliminary Plans • Draft (30%) and Final (60%) Preliminary Cost Estimate • Draft(30%) and Final (60%)Preliminary Basis of Design Report • Proposed Conditions Hydraulic Models All landowner outreach and stakeholder engagement associated with the preliminary design is included in Task 5 Stakeholder Engagement and Community Outreach. Regulatory permit application preparation, including delineation of wetlands and cultural resources assessment are included in Task 10. Subtask 7.1. Draft (30%) and Final (60%)Preliminary Plans Contractor will create a 30% design based on the preferred concept design alternative and further develop the 30% design to a 60%design level. It is anticipated design elements will include potential grading of channel features, engineered log jam locations, sizes and types, site restoration planting areas and silviculture treatments, stabilization of existing logjams,proposed relocation of existing facilities and/or infrastructure, and invasive species removal and control areas. Contractor will refine design elements to meet project goals and objectives as the project advances through the design process and stakeholder and community engagement process. We anticipate the following sheets to be included in the preliminary design drawing set: • Cover • General Notes • Legend • Existing Condition Site Overview • Access and Staging • Proposed Conditions Overview Plan • Proposed Conditions Plans at Site-Scale (1"=100' or less) • Engineered Log Jam Structure Details and Sequencing Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 8 of 19 • TESC Plan and Details • Invasive Plant Prevention Plan and Details a Site Restoration Plan and Plant Schedule(s) • Planting Details • Wood and Materials Schedule Subtask 7.2. Draft (30%) and Final (60%) Preliminary Construction Cost Estimate Contractor will update an estimate of probable construction cost based on the 30% and 60% designs. Contractor will use publicly available cost values (from WSDOT or the County for example), reaching out to suppliers, and examples from our past projects. Subtask 7.3. Draft(30%) and Final(60%) Preliminary Basis of Design Report Contractor will create a Basis of Design report for the 30% design and update it for the 60% design. The 30% design report will focus on the design layout and intended function of each restoration element, anticipated changes resulting from the project,updates to the hydraulic model, site restoration, and initial cost estimate. The 60%design report will add more detailed descriptions of engineering assumptions and calculations, further updates to the hydraulic model, a description of invasive plant prevention and treatment, site restoration plan, and updates to the construction cost estimate. Subtask 7.4. Proposed Conditions Hydraulic Models During development of the draft preliminary design, Contractor will prepare a proposed conditions hydraulic model of the project reach incorporating proposed restoration actions to evaluate the performance of the design relative to the project goals,to evaluate flooding and erosion risks, and to serve as the basis for documenting compliance with Jefferson County and National Floodplain Insurance Program (NFIP) code as part of Task 10 (Project Permitting). The suite of flows developed to characterize hydrology (Task 2) will be included as proposed condition models, as well as projected climate change flows,to ensure proposed elements are evaluated over a wide range of flow conditions. The results of the proposed hydraulic modeling will be used to modify the design to maximize benefits and minimize any potential adverse impacts,to anticipate future channel changes resulting from the restoration actions, and to facilitate early discussions with permit agencies. Once the design flood event has been selected the hydraulic model results will be used to assess stability of any proposed instream structures. Task Assumptions • OHWM boundaries will be developed from hydraulic model outputs, verified with field indications. Wetland boundaries will be approximated during field data collection (Subtask 1.1). • Property boundaries will be shown based on available parcel data. No boundary survey is included in this task. • Design drawings will be produced in Autodesk Civil 3D and delivered as 11"x 17" format PDFs. • Contractor will only submit the 30% and 60% deliverables for comment and review. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 9 of 19 • No hard copy or wet stamped versions of the plans will be produced. • Design plans will be prepared using NSD's CAD standards. • Project Special Provisions (Divisions 2 through 9) will utilize the Washington Department of Transportation (WSDOT, current year) Standard Specifications for Road, Bridge, and Municipal Construction, current edition. • Preliminary level of design will be used to apply for project permits under all applicable federal, state, and local regulations. • Contractor will receive one set of consolidated comments on the preliminary design. As part of this consolidation, County will resolve conflicting comments. Revisions to address comments will be completed during the final design task. • No archiving or e-transmittal of AutoCAD format (.dwg) files is included in this scope of work. • Planting plans will be prepared by others and are not included in this scope of work. • Construction support is not included in this scope of work. • Design effort does not include contaminant testing nor remediation. • Design effort does not include cultural resources investigations. • Design effort does not include utilities, stormwater, or roadway improvements. • Design effort does not include geotechnical investigation. • Design effort does not include floodplain analysis or permitting. • The level of effort for these deliverables has been set based on the assumption that review rounds do not exceed anticipated effort (1 round of review where noted) and no major design changes (revision of the number/location/type of structures) are requested. Task Deliverables: • October 2025 Draft (30%) Preliminary design drawings/plans, hydraulic model results, cost estimate, preliminary basis of design report, relevant appendices (hydraulic model results, stability calculations). • January 2026 Final (60%) Preliminary design drawings/plans, hydraulic model results, cost estimate, preliminary basis of design report, relevant appendices (hydraulic model results, stability calculations). Task 8. Invasive Plant Prevention Plan 10,000 Years Institute (Subcontractor), will design and implement an approach to managing invasive plants that is based on supporting native plant community succession. The plan will both describe the necessary ongoing survey and treatment of invasive plants in the Fletcher-TNC reach during the period of performance and will also detail the preferred approach to preventing the introduction and spread of invasive plants during future construction phases. Subcontractor will identify and describe sources, vectors and pathways of non-native invasive plants that impair and arrest the growth and resiliency of native plant communities in the project area. Subcontractor will utilize a local workforce to conduct persistent tracking and mapping followed by rapid control methods. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design, Attachment B Page l0 of 19 To limit the introduction and spread of new, existing, and previously seeded invasive plant species (IPS) during all phases of project implementation, Subcontractor will include the following in the Invasive Plant Prevention Plan: • Survey and treatment methods and schedule for target invasive plant species. • Maps and GIS locations of all previously documented IPS. Subcontractor will provide review, guidance, maps and GIS data as needed or requested. • Identification guidance for reporting observations. • Recommendations for: o Siting the most appropriate invasive-free access routes for truck and equipment use. o Siting the most suitable location for a vehicle and equipment wash station. o Equipment washing prior to entering and upon leaving construction zones, including between different sections of the Fletcher-TNC floodplain reaches. o Containing effluent to the wash station area with appropriately scaled pit. o Remediating the wash station area. Task Deliverables: • October 2025 Draft Invasive Plant Prevention Plan. • January 2026 Final Invasive Plant Prevention Plan. Task 9. Risk Assessment Contractor will describe the risk to existing infrastructure and private property from flooding and erosion under existing conditions and the final preliminary design. The assessment of risk will include the Upper Hoh Road, any utilities, private property and homes, as well as the risk of losing instream and associated floodplain salmonid habitats (e.g., side channels). The risk assessment will also include a description of boater safety under existing and proposed conditions to ensure the placement of instream structures will not increase risk. It will also evaluate how potential changes in river planform will affect flooding and erosion. Projected river trends and avulsion scenarios will be included to evaluate how risk changes as the main stem channel moves over time. The risk assessment will rely on the 2022 LiDAR, geomorphic assessment, and existing and proposed hydraulic model results to perform the needed analyses. Contractor has completed dozens of risk assessments and contributed to state guidelines developed by DNR Aquatic Lands. In addition to looking at risks to infrastructure and property under the no- action and proposed action alternatives, the risk to recreational boaters will be assessed. Natural and engineered log jams (ELJs) can pose risks to inexperienced boaters; thus, it is important to consider how they could interact with recreation. Over the last twenty years the hundreds of ELJs built in Washington have an excellent safety record. The Middle Hoh has historically had numerous snags and logjams which are regularly navigated by experienced boaters. Contractor will consider boater safety in all designs. Because of their stability, ELJs will be in known locations and thus become familiar to recreational users. All ELJs will be analyzed for stability and designed to be stable in a 100 yr flood(existing and projected for 2070 under latest climate models). Currently most natural logjams are unstable and form in different places year to year. The risk assessment will also examine the risk to habitat of the no-action alternative and proposed actions. The risk assessment will include the impacts associated with the warming climate. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 11 of 19 Assumptions • Much of the analysis will rely on existing and proposed hydraulic model outputs. Deliverables: • October 2025 Draft Risk Assessment appendix to the Preliminary Basis of Design Report. • January 2026 Final Risk Assessment appendix to the Preliminary Basis of Design Report. Task 10. Project Permitting Subtask 10.1. Wetlands Assessment and Delineation The Contractor will utilize the existing condition data collected in Task 1 regarding the estimated extent and nature of wetlands and alignment of OHWM indicators with the modeled 2-year flow to inform the development of the preliminary design. Those field efforts will build upon our team's knowledge of the geomorphic, habitat, and ecological conditions of the reach and serve as the baseline conditions against which we will evaluate proposed restoration actions. As the preliminary design progresses, we will complete a delineation of wetlands within the project area, leveraging our expertise in elevation-based wetland delineations to cover the large project area efficiently. Prior to field work, the contractor will complete a desktop review of National Wetland Inventory, Jefferson County wetland inventory, and National Resource Conservation Service (NRCS) soils mapper to identify areas of hydric soils and mapped wetlands and waters of the U.S. to support the subsequent field assessment. The delineation will include Washington State Department of Ecology (Ecology)required wetland rating forms for a suite of wetlands characteristics of those affected by the project. Contractor will complete the delineation within the area of potential effect (APE) derived from the preliminary design and will draft a delineation report with required Ecology rating form graphics, which will become a component of the project's permit application materials. The wetlands work will also help identify off-channel rearing and floodplain reconnection opportunities and support the analysis of project impacts and benefits that is required as part of the federal permitting process to show the net benefit of the project and alignment with the Corps' Nationwide Permit 27 pathway. Our approach is to integrate these elements early so the project can be designed to have a net benefit to aquatic species and habitats and so that impacts to wetlands and waters can be avoided,minimized and rectified. This approach is proven to effectively align the project with the Corps' Nationwide Permit 27 process and the USFWS and NMFS ESA programmatic, alignment with which creates a streamlined permitting process pathway for restoration actions. Subtask 10.2. Cultural Resources Assessment Successful environmental permitting of this project will require a comprehensive cultural resources assessment that can serve as Section 106 documentation for CWA 404 permitting by USACE, and for compliance with GEO 21-02 required by RCO funding. Contractor will work through our partner, Willamette Cultural Resources (Subcontractor),to complete archival review of the natural and cultural setting of the APE and vicinity (APE derived from the preliminary design). Results of this desktop study and any input willing to be shared by cultural resource staff of affected Tribes Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 12 of 19 (e.g., Hoh and Quileute Tribes, Quinault Indian Nation)will be used to gauge relative sensitivity for cultural resources that may be impacted by project restoration activities. If required by RCO, Subcontractor will then draft a cultural resource assessment workplan and vet the plan with RCO, DAHP, and affected Tribes. Once that consultation is completed, Subcontractor will complete a field survey with a level of effort tailored to relative sensitivity and anticipated project activities within the APE. The fieldwork will seek to identify cultural resources that may be impacted by the project so any such impact can be avoided. If any resources are identified, their significance and anticipated project effects will be assessed to the extent allowed during the fieldwork session. If additional fieldwork or archival research is needed to document and evaluate the historic register eligibility of a resource, it would be conducted under a separate scope of work. Subcontractor will then draft a technical report which will become a component of the project's permit application materials to summarize background research,methods and results of the fieldwork. The report will include evaluation of any resources that may be identified, concluding with recommendations regarding resources identified and any other cultural resources management measures that may be appropriate. Subcontractor will assist Contractor and the County through the consultation process required by Section 106 and GEO 21-02, coordinating with RCO, USACE, DAHP, and affected Tribes to ensure timely review of our cultural resource assessment documentation. Subtask 10.3. Permit Application Preparation, Submittals, and Process Management Contractor will support the County by initiating pre-application meetings with the federal and state agencies to review the project and answer questions prior to completion of the application materials. Contractor will then create the application materials and manage the application submittal and tracking process necessary to obtain federal, state, and local regulatory approvals for this project. Contractor proposes to leverage the active outreach to stakeholders, including federal and state regulatory agencies, completed as part of Task S to initiate conversations and identify the appropriate permit pathway. It is important to clarify the pathway early in the process since there are several possible pathways that influence each other, our level of effort, and the overall project schedule. Contractor will work directly with the County and WDFW to evaluate the potential for the project to align with either the Fish Habitat Enhancement Project (FHEP)HPA exemption that eliminates the need for local permitting, or the Habitat Recovery Pilot Program(HRPP), if that program is renewed by the State legislature before it expires in June of 2025. If the HRPP is renewed, or the project is determined to qualify for the FHEP process,then the project would not need to go through SEPA review nor the formal Shoreline permitting process. For federal permits, Consultant will design the project to qualify for a Clean Water Act Section 404 Nationwide 27 permit from the Corps and to be consistent with the Coastal Zone Management Act (CZMA)requirements. For ESA-listed species, Contractor will similarly aim for restoration actions that will be consistent with the action categories covered in the NMFS and USFWS restoration programmatic agreements with the Army Corps of Engineers. Contractor will prepare the appropriate ESA-consultation documents as determined through agency consultation(e.g., ABBE, Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 13 of 19 NEL, FPRP III form) while noting that the programmatics are currently set to expire before the permit submittals will occur for this project, creating some uncertainty. For Washington state's permitting agencies, a WDFW Hydraulic Project Approval (HPA)permit will be needed, as well as a Section 401 water quality certification from Ecology. We will prepare the pre-meeting request and 401 request forms as needed and coordinate in advance with WDFW as noted, and Ecology to verify pathways and processes. For example, for many projects of this scale, Ecology will require a Water Quality Monitoring Plan be submitted as part of the Section 401 water quality certification process. Contractor will leverage templates developed for other projects to efficiently complete this plan if required. It should be noted that the recent changes in federal regulatory jurisdiction of wetlands and some waters of the U.S. make the Contractor's approach of early and proactive coordination all the more critical to reaching construction permits in a timely and predictable manner. Contractor will also reach out to WADNR to determine the extent of DNR administered State- owned Aquatic Lands within the project area and will assist the County with the licensing process, if necessary. In addition, the project may need a Construction Stormwater National Pollutant Discharge Elimination System(CNPDES)permit if the area of disturbance exceeds 1 acre. If necessary, Contractor will assist the County in applying for that permit during the final design phase. Because the project reach is in a Special Flood Hazard Area(SFHA), Contractor will develop a design where the proposed hydraulic effects comply with minimum County and FEMA standards. Since the project reach is within an approximate SFHA Zone A, without a designated floodway nor assigned base flood elevations (BFEs), it is assumed that project actions can raise water up to 1-foot at the 100-year flood event(base flood). With our experience on rivers the size of the Hoh, it is likely we can propose ELJs in the channel without causing excessive rise,thus negating the need for any formal Letter of Map Change (LOMC)process. Contractor will introduce the project to Jefferson County Floodplain Development Code staff early on and determine the most efficient way to provide floodplain compliance documentation. Contractor will,utilize the existing conditions and proposed conditions 2D hydraulic model output developed for the design as the basis for documenting floodplain compliance for the County. In addition to meeting minimum County and NFIP flood code, we will also conduct a risk-assessment using the 2D hydraulic model to ensure no residences,private property, or infrastructure is at increased flood risk because of proposed actions. This risk assessment will be documented in the Basis of Design report. Contractor will develop the applications for the suite of local permits determined necessary based on the WDFW HPA pathway consultation. A Jefferson County clearing and grading permit may be required,particularly for developing staging areas and any temporary access routes. Depending on the resolution of the HPA process with WDFW, the project could also require a SEPA checklist and Shorelines permit process. Contractor will work with the County and WDFW to ideally align the project with the Restoration Pilot Program process which would avoid those requirements. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 14 of 19 Task Assumptions • No CLOMR. If CLOMR is needed, design will be modified to prevent need for CLOMR, or additional budget will be needed. • Contractor will serve as the Authorized Agent for County when submitting permit applications to the permitting agencies. • Budget assumes Nationwide Permit (NWP) conditions at the time of permitting will be in line with existing 2023 conditions. • Permit scope and budget is based on assumption that a standard HPA will be required. • Phase 1 design wetlands will be approximately mapped based on a 1-day site reconnaissance. Wetlands will not be flagged in the field. • Phase 1 wetland delineation assumes project area is <200 acres within which wetlands might be directly or indirectly impacted. • If needed, Contractor will develop the Notice of Intent(NOI) and Stormwater Pollution Prevention Plan(SWPPP)to support CNPDES application. • Ordinary high water will be approximated based on a hydraulic modelling output refined and calibrated to field data collected during the site reconnaissance. • The final engineering plans (11x17 sized)will accompany the permit applications. • Contractor will develop JARPA figures to support permit applications. • Since the project reach is not included in any FEMA or Jefferson County flood hazard mapping studies, a formal flood impacts analysis is not anticipated to be required so is not included here. A qualitative risk- assessment to downstream and adjacent infrastructure or property will be conducted and documented in the basis of design report. • For potential riparian treatments, Contractor will work with DNR to identify the appropriate approval process for that supplemental habitat enhancement work. Task Deliverables: • February 2026 Preparation and submittal of federal, state, and local permit applications, including JARPA, JARPA figures, ESA consultation documents, CZMA and Ecology 401 application materials including Water Quality Monitoring Plan, Floodplain Compliance documentation to Jefferson County, if required; WDFW APPS application for HPA, SEPA checklist, local county permit applications, WDNR Attachment E, if required; meetings, associated Wetland and Waters Delineation and Cultural Resources reports, and associated documentation. Task 11. Phase 1 Final Design Development Once the preliminary designs are complete, Contractor will work with the County to identify an area of the project reach to develop final designs. It is anticipated that recent channel changes will largely drive where Phase I will be located. Other considerations for locating Phase 1 may include permitting complexity, meeting floodplain compliance requirements, opportunistic/reactionary based on channel location, cost, and others. Contractor will leverage our experience implementing large, multi-phase projects like on the Quinault and Cispus Rivers,to develop a phased implementation approach that considers funding availability, landowner agreements, and ensuring project performance and risk are considered for the time period between construction phases. All Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 15 of 19 phases of construction will be stand-alone in that they will meet the project goals independent of completing future phases. The development of final plans, special provisions, and construction cost estimates are intended to support the construction bid process. Contractor will progress the 60%preliminary plan set following review by the permitting agencies, County, and larger stakeholder group including landowners. The development of the final plans, special provisions, and cost estimate will include the following tasks: • April 2026 Develop Draft(90%) Plans, Cost Estimate, Special Provisions, and 90% Basis of Design Report. • May 2026 Develop Draft(90%)Plans, Cost Estimate, Special Provisions, and 90% Basis of Design Report. • May 2026 Proposed Conditions Hydraulic Models. All landowner outreach and stakeholder engagement associated with the final design is included in Task 5 Stakeholder Engagement and Community Outreach. Subtask 11.1. Develop Draft(90%) and Final (100%) Plans, Cost Estimate, and Special Provisions Contractor will use feedback from the County,permitters, landowners, and project stakeholders, to advance the design and associated construction plans to Final Design. Design modifications which are supported through analysis will be included in the final design submittal package. The construction cost estimate and Basis of Design report will also be updated and finalized as part of this task. Major design changes are not anticipated and are not included in this scope, however an updated air photo of the final design area will be acquired prior to finalizing the final design. This air photo will be used to make any changes needed to the design to accommodate changes in the main stem channel location during the multi-year design process, like changing temporary access route and staging area locations. The final construction plans, cost estimate, and special provisions will be reviewed and certified by a Professional Engineer registered to practice in the state of Washington. Contractor will also prepare a stand-alone spreadsheet of construction materials and quantities (Bid Tab). Contractor will prepare construction special provisions that will follow WSDOT Standard Specifications and Special Provisions standard format. Construction special provisions prepared by Contractor will be limited to project-specific special provisions (Divisions 2-9); no Division 1 special provisions related to contracting are included as part of this scope of work. If project specific Division 1 special provisions are necessary, Contractor assumes they will be prepared by the County. Contractor will prepare a final, stamped plan set and final construction special provisions to be used for contractor bid documents as prepared by others. Subtask 11.2. Develop Draft(90%) and Final(100%) Basis of Design Report Contractor will update and finalize the Basis of Design report prepared for the 60% designs to reflect the final design. This will include an update of the description of engineering assumptions and calculations, function of each restoration element, and updated final hydraulic model output, if necessary. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design,Attachment B Page 16of19 Subtask 11.3. Proposed Conditions Hydraulic Models During development of the draft final design, Contractor will update the proposed conditions hydraulic model of the project reach developed during preliminary design incorporating any changes to proposed restoration actions. The models will be used to evaluate any changes in hydraulic conditions as a result of the design modifications to ensure the project goals are met and flooding and erosion risks have not increased as a result. The suite of flows developed to characterize hydrology (Task 2)will be included as proposed condition models, as well as projected climate change flows, to ensure proposed elements are evaluated over a wide range of flow conditions. Task Assumptions • Permit agency and stakeholder comments on the Final 60% plans will be provided by County and incorporated into the Final Design. • County will be responsible for Division 1 of the Special Provisions. • The bid package will be compiled by the County. • All review will be addressed between the 60% Design and submittal of the Final Design. • The level of effort for these deliverables has been set based on the assumption that review rounds do not exceed anticipated effort(1 round of review where noted) and no major design changes (revision of the number/location/type of structures) are requested. • Bidding and Construction Support is not included in this scope or fee estimate. Task Deliverables: • April 2026 Draft(90%) Final design drawings/plans, hydraulic model results, cost estimate,Final Basis of Design Report, relevant appendices (hydraulic model results, stability calculations). • May 2026 Final(100%) design drawings/plans, hydraulic model results, cost estimate (Final PS&E), Final Basis of Design Report,relevant appendices (hydraulic model results, stability calculations).

Riparian Forest and Floodplain Wetlands Condition Field Assessment Contractor will characterize riparian floodplain conditions within the project reach. The riparian forestry mapping in the project reach completed for the Resiliency Plan will be updated using the 2022 LiDAR and verified in the field for accuracy. Contractor will complete a desktop review of Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 14 of 33 National Wetland Inventory, Jefferson County wetland inventory, and National Resource Conservation Service (NRCS) soils mapper to identify areas of hydric soils and mapped wetlands and waters of the U.S. to support the subsequent field assessment. It is anticipated that 3 days of fieldwork will be required to fully assess this reach. The field verification effort will focus on collecting existing conditions data on: • Riparian stand composition and condition • Floodplain vegetation communities • Extent and nature of wetlands proximate to the channel to determine extent of existing connectivity to key salmonid rearing habitats and opportunities for improved connectivity • Indicators of the Ordinary High Water Mark(OHWM)to correlate with the existing conditions hydraulic modeling (Task 2) and ultimately support Task 10 Project Permitting Subtask 1.2. Habitat and Fish Use Field Assessment Contractor will collect instream and off-channel habitat conditions within the project reach. It is anticipated that 5 days of field work will be required to fully assess this reach. The habitat assessment will include the collection of the following data in the mainstem river and side channels: • Chinook, coho, and steelhead spawning and rearing habitat • Presence of juvenile salmonids • Annual spring and fall Chinook, coho, and steelhead spawning surveys • Sharing salmonid redd data over time to document usage of the main stem and side channels • Location and geometry of side channels and flow condition • Size and location of pools, large wood, logjams Subtask 1.3. Geomorphic Field Assessment Contractor will document and characterize active and impaired geomorphic processes in the reach, as well as record existing habitat protection and restoration opportunities. Data to be acquired to support the geomorphic assessment and deign include: • Active bank erosion • Significant local sediment inputs • Pebble counts sufficient to characterize mapped channels • Active deposition and/or incision • Bank protection • Field verification of relative elevation model (REM) • Design constraints Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 15 of 33 Task Assumptions • County will coordinate permission to access private property needed for field surveys. • River flows will be sufficiently low as to not restrict access to perform field work safely. • Landowner meetings will not occur during field data visits. • Travel costs and field equipment use will be billed as expenses and are included in costs. • Additional topographic information will only be collected if deemed necessary at high- risk locations. Task Deliverables: • Existing conditions characterization chapter for basis of design report relevant map appendix. Task 2. Existing Conditions Reach Hydrology & Hydraulics Development of an existing conditions hydraulic model of the project reach will be a critical tool for understanding flow patterns during seasonal and flood levels, identifying restoration opportunities, characterizing the extent of floodplain wetland connection currently occurring, and developing concept designs. Subtask 2.1. Hydrology Hydrology for the hydraulic model will be developed by analyzing USGS gages (#12041200, #12041000)using Bulletin 17C guidelines (USGS 2018). Recurrence flows for the un-gaged tributaries will be estimated using regional regression equations developed by Mastin et. al. (2016). Major tributary inputs (Tower, Clear, Red, Lindner, and Willoughby Creeks) will be included in the model simulations to account for their flow contributions, assuming a similar flow recurrence is occurring in the tributary and the main stem Hoh River concurrently (the 2-yr flow simulation for the Hoh River will include tributary inputs also at the 2-yr flow). Low flow discharge for the Hoh and tributaries will be estimated using methods outlined in Curran et. al. (2012). The impacts of climate change have already begun to alter the flow regime in the Hoh River watershed, increasing peak flow frequency and magnitude over time, while simultaneously decreasing summer baseflow. Recent flood history will be described and put in context with historic peak flow timing and trends in the basin to demonstrate how peak flows have already changed. Projecting future changes to flow is included in a later task describing climate change impacts. Subtask 2.2. Hydraulics Contractor will develop a 2-dimensional (2D) hydraulic model using the US Army Corps HEC- RAS program. The model will encompass the project reach and utilize 2022 bathymetric LiDAR acquired by the Hoh Tribe as the primary source of topography for the model mesh. To ensure boundary conditions are not influencing results within the project reach,the 2D hydraulic model will be extended up to Spruce Canyon(near RM 25.5) and down to Schmidt Bar(near RM 19.5) where the valley naturally confines the channel. Risk based and geomorphically relevant flow simulations will be performed for the 1, 2, 10, 25, 50, and 100-yr recurrence floods. In addition, flows during Winter Steelhead and Spring Chinook Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 16 of 33 Salmon spawning periods will be modeled under existing conditions, to assess existing velocity and depth conditions during this critical life history stage to evaluate habitat suitability. Proposed condition model iterations will consider the same parameters to understand proposed habitat lift at the as-built condition. This information will guide design of optimal ecological outcomes and offer a useful communication tool for community members and other key stakeholders by species during spawning times. The existing conditions 2-year flow output from the 2D hydraulic model will be compared to data collected in Task 1 relative to the Ordinary High-Water Mark(OHWM) to support delineation of that regulatory boundary (Task 10) and to characterize the extent to which floodplain surfaces, side channels, and associated wetlands are currently connected to flood flows. This data will be used in Task 10 to support the development of permit application materials and the demonstration and quantification of benefits to aquatic habitats, including wetlands. The development and results of the existing conditions 2D hydraulic model, flow recurrence calculations and estimates, and recent trends in peak flows will all be detailed in a chapter of the basis of design report, including an appendix of maps illustrating the model results. Development of all proposed conditions, model simulations used for design development and FEMA compliance are included in later tasks. Task Assumptions • Streamflow estimates will follow USGS Bulletin 17B/C guidelines for gaged sites and using regional values for skew and standard error. No additional field streamflow measurements or gaging instrumentation are needed. USGS StreamStats will be used where no stream gage information is available. * Models will not be calibrated to regulatory (e.g. FEMA FIS) models or existing benchmarks. Task Deliverables: • Reach Hydrology & Hydraulics chapter within the basis of design report, including relevant figures and map appendix. Task 3. Reach Geomorphology Contractor will document historic disturbances in the project reach that have impaired natural geomorphic process and broken the large wood cycle,resulting in a more dynamic and unstable system that lacks reliable instream and off-channel habitat for salmonids, and a river that regularly poses flooding and erosion risk to the community. Understanding the underlying mechanisms that continue to impair habitat availability and contribute to instability is critical to developing a restoration strategy that will put the system on a sustainable path to recovery. Historic air photos,maps, and existing geospatial data will be used to characterize how the channel and floodplain have evolved over time in the project reach. Channel migration rates will be quantified over time, channel avulsions will be documented, and the influence of large wood and logjams in the reach on channel migration and avulsions will be described. Remaining patches of old growth forest in the floodplain, more resistant to erosion,will be delineated and erosion rates compared to areas with less mature vegetation. The unvegetated active channel will also be Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 17 of 33 delineated on historic air photos to measure change in area over time. Pre-disturbance channel migration and avulsion rates, unvegetated active channel area, and the role of large wood and logjams will be compared with those measured in the disturbed project reach using a reference reach on the Queets River between RM 19 and 23 that has a similar drainage area as the Lindner Reach. The 2013/14 LiDAR of the project reach will be compared with the more recent 2022 LiDAR to quantify the magnitude and spatial distribution of changes between the two data sets. Peak flows occurring in the time period between LiDAR flights will be used to place the magnitude of changes in context with recent flood history. We will use the composite 2013/14 surface that includes the LiDAR data and channel bathymetry collected by Wild Fish Conservancy in 2014 to compare not only the overall changes to the surface,but also target changes specific to the channel thalweg over time. The data and methods used for the geomorphic assessment will be detailed, along with results and implications for the design, and will be included in a chapter in the basis of design report, including maps and figures as needed to illustrate the results. Task Assumptions • Only publicly available georeferenced photos, including those used for the Resiliency Plan, will be used in the geomorphic assessment,NSD will not georeference additional historical aerial photos that do not have spatial metadata. Task Deliverables: • Reach Geomorphology chapter within the basis of design report, including relevant figures and appendices. Task 4. Climate Change Contractor will utilize the river-scale findings from the Middle Hoh River Resiliency Plan(NSD 2022)to estimate the resiliency benefits of concept design alternatives under potential climate change conditions at the reach-scale. Any new climate model predictions that have been done since the Resiliency Plan will be incorporated into the assessment. At the watershed-scale, higher precipitation rates due to ongoing climate change effects will increase the magnitude of annual peak and average winter flows and contribute to increases in mass-wasting and sediment delivery to the river. Contractor will verify and apply these watershed-scale findings to the reach-scale to analyze the following: • The potential effects of increased sediment delivery on the project reach in terms of channel bed aggradation, flooding, and channel migration. • How increases in flow may expand flooding extent in the project reach and contribute to increases in channel migration rates. • Impacts on the potential extent and availability of off-channel habitat for salmonid species. • Potential impacts of erosion and channel migration on mature riparian and floodplain forest. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 18 of'33 • Potential impacts to infrastructure and private property. • Climate change mitigation opportunities will be evaluated as a part of Task 6: Concept Design Development. • Recent channel changes, within the last 25-years, will be analyzed as a part of Task 3: Reach Geomorphology. • The effects of climate change on peak flows will be simulated for each concept design alternative and the preliminary design as a part of Task 6 and Task 7,respectively using flows predicted in Task 4. • The effects of climate change on ESA listed Bull Trout(S. Confluentes)who require cold, complex habitat to survive, and are therefore extremely sensitive to increasing temperatures. Task Deliverables: • Climate Change chapter within the basis of design report, including relevant figures and appendices. Task 5. Stakeholder Engagement&Community Outreach • At the start of the project Contractor will work with County to develop an Engagement and Outreach Plan,to detail the process and schedule by which the project will connect with landowners, communicate with the Hoh Tribe and other identified groups and the public, and solicit input for the entire project, including final design development. It is anticipated the Plan will include the following: • Making presentations and providing workshop or site visit materials at up to two watershed-level "Hoh River Resiliency" events (in person at various Hoh River, Forks, or project locations) with interested community members in the watershed in 2025 and/or 2026. • Convene and facilitate four meetings for a new ad hoc Lindner Reach Technical Advisory Group (online or hybrid)that includes representatives from relevant permit agencies, County, and local technical experts including the Hoh Tribe at key design milestones including: o Completion of existing conditions characterization, draft concept designs, ranking and selection o Completion of 30%design o Completion of 60%design o Completion of 90%design • Present to Hoh Tribal Council, County leadership, City of Forks, user and/or economic groups (recreational boaters, guides, fishers, etc.), or other stakeholders (up to 10 in person meetings at various local locations.) • Meet individually up to a combined 40 times with the Hoh Tribe, individual landowners, local businesses, and/or specific user groups (in person—Hoh River or North Olympic Peninsula) Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 19 of 33 With input from project partners, Contractor will support the County to organize, convene, and facilitate public meetings, technical meetings, and meetings with individual stakeholders and landowners. Contractor will contribute to and review Agency-led outreach products including a watershed newsletter. As feasible,the project will offer opportunities to involve local community, faculty, and students from the new Natural Resources Program at Peninsula College in Forks: https://pencol.edu/program/natural-resources.Notes from all meetings will be included in the basis of design report, with relevant outcomes and content covered at each. Task Assumptions: • County is responsible for scheduling and coordinating meetings and events except mutually agreed upon landowner meetings. Task Deliverables: • Engagement and Outreach Plan and Community Outreach and Engagement chapter for basis of design report. • 2 Hoh River Resiliency events (in person). • 4 TWG meetings (online/in person). • Total of 10 meetings with several groups including Hoh Tribal Council, County leadership, City of Forks (in person). • Up to 40 meetings with landowners, local businesses, and river user groups in the reach (in person). Task 6. Concept Design Development High-level concept designs were created for this reach as a part of the Middle Hoh Resiliency Action Plan. These concepts include actions to sustain side-channel habitat for salmonids, potential relocation of Jefferson County Public Works facilities, installation of engineered log jams (ELJs)to protect infrastructure, preserve valuable existing salmonid habitat and prevent large mass-wasting events or avulsion events in the project reach. Contractor will re-evaluate these initial concept ideas within the context of a more-detailed existing conditions characterization(Tasks 1 -3), climate change impacts (Task 4), and up-to-date stakeholder and community input(Task 6). Following the completion of the Existing Conditions Characterization Tasks and Climate Change Impacts Task(Tasks 1 - 4), Contractor will work with the County to develop up to 3 conceptual design alternatives for the Lindner Complex Reach. The design team will collaborate with the County on development and evaluation of different design alternatives to achieve the project goals and objectives. The 2D hydraulic model developed in Task 3 will be updated to depict each alternative to determine possible side channel flow pathways and to identify flood hazards and range of ecological benefits to aquatic and floodplain wetland habitats. Large wood structures will be incorporated into the model mesh to investigate hydraulic influence. The benefits of each alternative will be compared, and the hydraulic models will be reviewed, to analyze the potential need for a CLOMR and potential for floodplain wetland restoration and riparian community enhancement. Compliance with floodplain regulations will be an important consideration in evaluation of design alternatives. Evaluation criteria that may be considered include wetland restoration and aquatic habitat improvements, anticipated geomorphic response, Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 20 of 33 construction feasibility, regulatory complexity and timeline, infrastructure impacts, and cost. A no action alternative will be included that compares the evaluation criteria for the proposed concept designs to current approaches relying on emergency riprap and designed projects utilizing dolos. Initial consultation with regulatory agencies during the conceptual design phase will be completed as part of Task 10 to clearly understand the implications and complexity of each alternative and to contrast with no action and road-first protections. Permit application preparation, including the cultural resources assessment and wetland delineation,will occur during and following the selection of the preferred alternative and advancement through the Preliminary Design phase (Task 7). Contractor will draft plan view maps of the design alternatives and describe project elements in relation to project goals and objectives as well as potential modification to existing habitats, land use and regulatory constraints. The design evaluation is anticipated to include discussion of the type, size, and proposed quantity of wood placements within the side channel and related ecological benefits, in addition to other design criteria. Contractor will document evaluation of design alternatives as part of the Conceptual Design Development chapter within the basis of design report, including recommendation of a preferred design alternative and submit the draft report to the County for review. County will provide review comments and guidance regarding decision on selecting a preferred alternative that will be advanced to a preliminary design stage in the next task. Contractor will revise the working draft of the Conceptual Design. The Development chapter will incorporate the County's review comments as part of the basis for selecting the preferred alternative. The revised draft will provide a deliverable that can be shared with the SRFB review panel and other stakeholders for additional review. The design and deliverables will meet the requirements presented in Manual 18: Salmon Recovery Grants. Task Assumptions • Reporting for conceptual designs will focus on treatment methods and screening criteria and will not be detailed site-specific design. • Detailed design will not occur at this phase of the project. • County will select a Preferred Design to move forward into Preliminary Design • County will provide one round of consolidated review and comment on draft deliverables. Comments and any subsequent design revisions will be incorporated during Preliminary Design(on all concept design deliverables). • Conceptual design sheets will be provided in 11x17 pdf format and will be limited to simple plan view representations of proposed actions under each alternative. • Up to three (3)proposed conditions alternatives will be considered. • Hydraulic modeling of design alternatives will utilize the same hydrology and model flows developed for Task 3. • Potential impacts to the regulatory floodway will be considered during alternative development and analysis. • The project will not progress into preliminary design until the County selects a preferred alternative. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 21 of 33 • Contractor will not develop special provisions as part of the concept designs. • Cost estimates will be developed as rough order of magnitude estimates and will use rolled up cost line items that are anticipated to be refined in final design. Task Deliverables: • Concept Design Development chapter within the basis of design report, including three concept design alternative drawings/plans, maps comparing changes in hydraulic conditions for each design alternative relative to existing condition, ranking matrix for concept design comparison. Task 7. Preliminary Design Development The preliminary design plans are intended to be permit-ready plans for use in initiating project permitting discussions with the County, Tribal and federal, state, and local regulatory agencies. The development of the 60% plans will include the following subtasks: • Draft(30%) and Final(60%) Preliminary Plans • Draft(30%) and Final(60%) Preliminary.Cost Estimate • Draft(30%)and Final(60%)Preliminary Basis of Design Report • Proposed Conditions Hydraulic Models All landowner outreach and stakeholder engagement associated with the preliminary design is included in Task 5 Stakeholder Engagement and Community Outreach. Regulatory permit application preparation, including delineation of wetlands and cultural resources assessment are included in Task 10. Subtask 7.1. Draft (30%) and Final(60%) Preliminary Plans Contractor will create a 30%design based on the preferred concept design alternative and further develop the 30% design to a 60% design level. It is anticipated design elements will include potential grading of channel features, engineered log jam locations, sizes and types, site restoration planting areas and silviculture treatments, stabilization of existing logjams,proposed relocation of existing facilities and/or infrastructure, and invasive species removal and control areas. Contractor will refine design elements to meet project goals and objectives as the project advances through the design process and stakeholder and community engagement process. We anticipate the following sheets to be included in the preliminary design drawing set: • Cover • General Notes • Legend • Existing Condition Site Overview • Access and Staging • Proposed Conditions Overview Plan • Proposed Conditions Plans at Site-Scale (1" =100' or less) Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 22 of 33 • Cross-Sections • Profiles(s) • Engineered Log Jam Structure Details and Sequencing • TESC Plan and Details • Invasive Plant Prevention Plan and Details • Site Restoration Plan and Plant Schedule(s) • Planting Details • Wood and Materials Schedule Subtask 7.1. Draft (30%) and Final (60%) Preliminary Construction Cost Estimate Contractor will update an estimate of probable construction cost based on the 30% and 60% designs. Contractor will use publicly available cost values (from WSDOT or the County for example), reaching out to suppliers, and examples from our past projects. Subtask 7.2. Draft (30%) and Final (60%) Preliminary Basis of Design Report Contractor will create a Basis of Design report for the 30% design and update it for the 60%design. The 30% design report will focus on the design layout and intended function of each restoration element, anticipated changes resulting from the project, updates to the hydraulic model, site restoration,and initial cost estimate. The 60% design report will add more detailed descriptions of engineering assumptions and calculations, further updates to the hydraulic model, a description of invasive plant prevention and treatment, site restoration plan, and updates to the construction cost estimate. Subtask 7.3. Proposed Conditions Hydraulic Models During development of the draft preliminary design, Contractor will prepare a proposed conditions hydraulic model of the project reach incorporating proposed restoration actions to evaluate the performance of the design relative to the project goals,to evaluate flooding and erosion risks, and to serve as the basis for documenting compliance with Jefferson County and National Floodplain Insurance Program (NFIP) code as part of Task 10 (Project Permitting). The suite of flows developed to characterize hydrology (Task 2)will be included as proposed condition models, as well as projected climate change flows,to ensure proposed elements are evaluated over a wide range of flow conditions. The results of the proposed hydraulic modeling will be used to modify the design to maximize benefits and minimize any potential adverse impacts,to anticipate future channel changes resulting from the restoration actions, and to facilitate early discussions with permit agencies. Once the design flood event has been selected the hydraulic model results will be used to assess stability of any proposed instream structures. Task Assumptions: • OHWM boundaries will be developed from hydraulic model outputs, verified with field indications. Wetland boundaries will be approximated during field data collection (Subtask 1.1). Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 23 of 33 • Property boundaries will be shown based on available parcel data. No boundary survey is included in this task. • Design drawings will be produced in Autodesk Civil 3D and delivered as 11"x 17" format PDFs. • Contractor will only submit the 30% and 60% deliverables for comment and review. • No hard copy or wet stamped versions of the plans will be produced. • Design plans will be prepared using NSD's CAD standards. • Project Special Provisions(Divisions 2 through 9)will utilize the Washington Department of Transportation(WSDOT, current year) Standard Specifications for Road, Bridge, and Municipal Construction, current edition. • Preliminary level of design will be used to apply for project permits under all applicable federal, state, and local regulations. • Contractor will receive one set of consolidated comments on the preliminary design. As part of this consolidation, County will resolve conflicting comments. Revisions to address comments will be completed during the final design task. • No archiving or e-transmittal of AutoCAD format (.dwg) files is included in this scope of work. • Planting plans will be prepared by others and are not included in this scope of work. • Construction support is not included in this scope of work. • Design effort does not include contaminant testing nor remediation. • Design effort does not include cultural resources investigations. • Design effort does not include utilities, stormwater, or roadway improvements. • Design effort does not include geotechnical investigation. • Design effort does not include floodplain analysis or permitting. • The level of effort for these deliverables has been set based on the assumption that review rounds do not exceed anticipated effort(1 round of review where noted) and no major design changes (revision of the number/location/type of structures) are requested. Task Deliverables: • Draft(30%) and Final(60%) Preliminary design drawings/plans,hydraulic model results, cost estimate,preliminary basis of design report,relevant appendices(hydraulic model results, stability calculations). Task 8. Invasive Plant Prevention Plan 10,000 Years Institute (Subcontractor), will design and implement an approach to managing invasive plants that is based on supporting native plant community succession. The plan will both describe the necessary ongoing survey and treatment of invasive plants in the Lindner Complex during the period of performance and will also detail the preferred approach to preventing the introduction and spread of invasive plants during future construction phases. Subcontractor will identify and describe sources, vectors and pathways of non-native invasive plants that impair and Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 24 of 33 arrest the growth and resiliency of native plant communities in the project area. Subcontractor will utilize a local workforce to conduct persistent tracking and mapping followed by rapid control methods. To limit the introduction and spread of new, existing, and previously seeded invasive plant species (IPS) during all phases of project implementation, Subcontractor will include the following in the Invasive Plant Prevention Plan: • Survey and treatment methods and schedule for target invasive plant species. • Maps and GIS locations of all previously documented IPS. Subcontractor will provide review, guidance, maps and GIS data as needed or requested. • Identification guidance for reporting observations. • Recommendations for: o Siting the most appropriate invasive-free access routes for truck and equipment use. o Siting the most suitable location for a vehicle and equipment wash station. o Equipment washing prior to entering and upon leaving construction zones, including between different sections of the Lindner floodplain reaches. o Containing effluent to the wash station area with appropriately scaled pit. o Remediating the wash station area. Task Deliverables: • Draft and Final Invasive Plant Prevention Plan. Task 9. Risk Assessment Contractor will describe the risk to existing infrastructure and private property from flooding and erosion under existing conditions and the final preliminary design. The assessment of risk will include the Upper Hoh Road, Jefferson County Public Works facility, local businesses,private property and homes, as well as the risk of losing instream and associated floodplain salmonid habitats (e.g., side channels). The risk assessment will also include a description of boater safety under existing and proposed conditions to ensure the placement of instream structures will not increase risk. It will also evaluate how potential changes in river planform will affect flooding and erosion. Projected river trends and avulsion scenarios will be included to evaluate how risk changes as the main stem channel moves over time. The risk assessment will rely on the 2022 LiDAR, geomorphic assessment, and existing and proposed hydraulic model results to perform the needed analyses. Contractor has completed dozens of risk assessments and contributed to state guidelines developed by DNR Aquatic Lands. In addition to looking at risks to infrastructure and property under the no- action and proposed action alternatives,the risk to recreational boaters will be assessed. Natural and engineered logjams (ELJs) can pose risks to inexperienced boaters; thus, it is important to consider how they could interact with recreation. Over the last twenty years the hundreds of ELJs built in Washington have an excellent safety record. The Middle Hoh has historically had numerous snags and logjams which are regularly navigated by experienced boaters. Contractor will consider boater safety in all designs. Because of Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 25 of 33 their stability, ELJs will be in known locations and thus become familiar to recreational users. All ELJs will be analyzed for stability and designed to be stable in a 100 yr flood(existing and projected for 2070 under latest climate models). Currently most natural logjams are unstable and form in different places year to year. The risk assessment will also examine the risk to habitat of the no-action alternative and proposed actions. The risk assessment will include the impacts associated with the warming climate. Assumptions • Much of the analysis will rely on existing and proposed hydraulic model outputs. Deliverables: • Draft and Final Risk Assessment appendix to the Final Basis of Design Report. Task 10. Project Permitting Subtask 10.1. Wetlands Assessment and Delineation The Contractor will utilize the existing condition data collected in Task 1 regarding the estimated extent and nature of wetlands and alignment of OHWM indicators with the modeled 2-year flow to inform the development of the preliminary design. Those field efforts will build upon our team's knowledge of the geomorphic, habitat, and ecological conditions of the reach and serve as the baseline conditions against which we will evaluate proposed restoration actions. As the preliminary design progresses, we will complete a delineation of wetlands within the project area, leveraging our expertise in elevation-based wetland delineations to cover the large project area efficiently. The delineation will include Washington State Department of Ecology (Ecology) required wetland rating forms for a suite of wetlands characteristics of those affected by the project, an approach we have used on several projects in the Chehalis River basin to save budget while meeting permit application requirements. Contractor will complete the delineation within the area of potential effect(APE) derived from the preliminary design and will draft a delineation report with required Ecology rating form graphics, which will become a component of the project's permit application materials. The wetlands work will also help identify off-channel rearing and floodplain reconnection opportunities and support the analysis of project impacts and benefits that is required as part of the federal permitting process to show the net benefit of the project and alignment with the Corps' Nationwide Permit 27 pathway. Our approach is to integrate these elements early so the project can be designed to have a net benefit to aquatic species and habitats and so that impacts to wetlands and waters can be avoided,minimized and rectified. This approach is proven to effectively align the project with the Corps' Nationwide Permit 27 process and the USFWS and NMFS ESA programmatic, alignment with which creates a streamlined permitting process pathway for restoration actions. Subtask 10.2. Cultural Resources Assessment Successful environmental permitting of this project will require a comprehensive cultural resources assessment that can serve as Section 106 documentation for CWA 404 permitting by USACE, and for compliance with GEO 21-02 required by RCO funding. Contractor will work through our Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 26 of 33 partner, Willamette (Subcontractor), to complete archival review of the natural and cultural setting of the APE vicinity (APE derived from the preliminary design). Results of this desktop study and any input willing to be shared by cultural resource staff of affected Tribes (e.g., Hoh and Quileute Tribes, Quinault Indian Nation)will be used to gauge relative sensitivity for cultural resources that may be impacted by project restoration activities. If required by RCO, Subcontractor will then draft a cultural resource assessment workplan and vet the plan with RCO, DAHP, and affected Tribes. Once that consultation is completed, Subcontractor will complete a field survey with a level of effort tailored to relative sensitivity and anticipated project activities within the APE. The fieldwork will seek to identify cultural resources that may be impacted by the project so any such impact can be avoided. If any resources are identified,their significance and anticipated project effects will be assessed to the extent allowed during the fieldwork session. If additional fieldwork or archival research is needed to document and evaluate the historic register eligibility of a resource, it would be conducted under a separate scope of work. Subcontractor will then draft a technical report which will become a component of the project's permit application materials to summarize background research, methods and results of the fieldwork. The report will include evaluation of any resources that may be identified, concluding with recommendations regarding resources identified and any other cultural resources management measures that may be appropriate. Subcontractor will assist Contractor and the County through the consultation process required by Section 106 and GEO 21-02, coordinating with RCO, USACE, DAHP, and affected Tribes to ensure timely review of our cultural resource assessment documentation. Subtask 10.3. Permit Application Preparation, Submittals, and Process Management Contractor will support the County by initiating pre-application meetings with the federal and state agencies to review the project and answer questions prior to completion of the application materials. Contractor will then create the application materials and manage the application submittal and tracking process necessary to obtain federal, state, and local regulatory approvals for this project. Contractor proposes to leverage the active outreach to stakeholders, including federal and state regulatory agencies, completed as part of Task 5 to initiate conversations and identify the appropriate permit pathway. It is important to clarify the pathway early in the process since there are several possible pathways that influence each other, our level of effort, and the overall project schedule. Contractor will work directly with the County and WDFW to evaluate the potential for the project to align with either the Fish Habitat Enhancement Project(FHEP) HPA exemption that eliminates the need for local permitting, or the Habitat Recovery Pilot Program(HRPP). If the HRPP is approved by WDFW, then the project would not need to go through SEPA review nor the formal Shoreline permitting process. For federal permits, Consultant will design the project to qualify for a Clean Water Act Section 404 Nationwide 27 permit from the Corps and to be consistent with the Coastal Zone Management Act (CZMA)requirements. For ESA-listed species, Contractor will similarly aim for restoration actions Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 27 of 33 that will be consistent with the action categories covered in the NMFS and USFWS restoration programmatic agreements with the Army Corps of Engineers. Contractor will prepare the appropriate ESA-consultation documents as determined through agency consultation(e.g., ABBE, NEL, FPRP III form) while noting that the programmatics are currently set to expire before the permit submittals will occur for this project, creating some uncertainty. For Washington state's permitting agencies, a WDFW Hydraulic Project Approval (HPA)permit will be needed, as well as a Section 401 water quality certification from Ecology. We will prepare the pre-meeting request and 401 request forms as needed and coordinate in advance with WDFW as noted, and Ecology to verify pathways and processes. For example, for many projects of this scale, Ecology will require a Water Quality monitoring plan be submitted as part of the Section 401 water quality certification process. Contractor will leverage templates developed for other projects to efficiently complete this plan if required. It should be noted that the recent changes in federal regulatory jurisdiction of wetlands and some waters of the U.S. make the Contractor's approach of early and proactive coordination all the more critical to reaching construction permits in a timely and predictable manner. Contractor will also reach out to WA DNR to determine the extent of DNR administered State- owned Aquatic Lands within the project area and will assist the County with the easement process, if necessary. In addition, the project may need a Construction Stormwater National Pollutant Discharge Elimination System (CNPDES) permit if the area of disturbance exceeds 1 acre. If necessary, Contractor will assist the County in applying for that permit during the final design phase. Because the project reach is in a Special Flood Hazard Area(SFHA), Contractor will develop a design where the proposed hydraulic effects comply with minimum County and FEMA standards. Since the project reach is within an approximate SFHA Zone A, without a designated floodway nor assigned base flood elevations (BFEs), it is assumed that project actions can raise water up to 1-foot at the 100-year flood event(base flood). With our experience on rivers the size of the Hoh, it is likely we can propose ELJs in the channel without causing excessive rise, thus negating the need for any formal Letter of Map Change (LOMC)process. Contractor will introduce the project to Jefferson County Floodplain Development Code staff early on and determine the most efficient way to provide floodplain compliance documentation. Contractor will utilize the existing conditions and proposed conditions 2D hydraulic model output developed for the design as the basis for documenting floodplain compliance for the County. In addition to meeting minimum County and NFIP flood code, we will also conduct a risk-assessment using the 2D hydraulic model to ensure no residences, private property, or infrastructure is at increased flood risk because of proposed actions. This risk assessment will be documented in the Basis of Design report. Contractor will develop the applications for the suite of local permits determined necessary based on the WDFW HPA pathway consultation. A Jefferson County clearing and grading permit may be required, particularly for developing staging areas and any temporary access routes. Depending on the resolution of the HPA process with WDFW,the project could also require a SEPA checklist and Shorelines permit process. Contractor will work with the County and WDFW to ideally align the project with the Restoration Pilot Program process which would avoid those requirements. Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 28 of33 Task Assumptions • No CLOMR. If CLOMR is needed, design will be modified to prevent need for CLOMR, or additional budget will be needed. • Contractor will serve as the Authorized Agent for County when submitting permit applications to the permitting agencies. • Budget assumes NWP spell out? conditions at the time of permitting will be in line with existing 2023 conditions. • Permit scope and budget is based on assumption that WDFW will use the HRPP pathway and County will not require SEPA Determination or Shoreline Development permits. • Phase 1 design wetlands will be approximately mapped based on a 2-day site reconnaissance. Wetlands will not be flagged in the field. • Phase 1 wetland delineation assumes project area is <200 acres within which wetlands might be directly or indirectly impacted. • If needed, Contractor will develop the Notice of Intent(NOI) and Stoititwater Pollution Prevention Plan (SWPPP)to support CNPDES application. • Ordinary high water will be approximated based on a hydraulic modelling output refined and calibrated to field data collected during the site reconnaissance. • The final engineering plans (11x17 sized) will accompany the permit applications. • Contractor will develop JARPA figures to support permit applications. • Since the project reach is not included in any FEMA or Jefferson County flood hazard mapping studies, a formal flood impacts analysis is not anticipated to be required so is not included here. A qualitative risk- assessment to downstream and adjacent infrastructure or property will be conducted and documented in the basis of design report. • For potential riparian treatments, Contractor will work with DNR to identify the appropriate approval process for that supplemental habitat enhancement work. Task Deliverables: • Preparation and submittal of federal, state, and local permit applications, including JARPA, JARPA figures, ESA consultation documents, CZMA and Ecology 401 application materials including Water Quality Monitoring Plan, Floodplain Compliance documentation to Jefferson County, if required; WDFW APPS application for HPA, WDNR Attachment E, if required; meetings, associated Wetland and Waters Delineation and Cultural Resources reports, and associated documentation. Task 11. Phase 1 Final Design Development Once the preliminary designs are complete, Contractor will work with the County to identify an area of the project reach to develop final designs. It is anticipated that landowner agreements will largely drive where a Phase I can be developed. Other considerations for locating Phase 1 may include permitting complexity, meeting floodplain compliance requirements, Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3, PAO Approved 7/12/2021 Page 29 of 33 opportunistic/reactionary based on channel location, cost, and others. Contractor will leverage our experience implementing large, multi-phase projects like on the Quinault and Cispus Rivers,to develop a phased implementation approach that considers funding availability, landowner agreements, and ensuring project performance and risk are considered for the time period between construction phases. All phases of construction will be stand-alone in that they will meet the project goals independent of completing future phases. The development of final plans, special provisions, and construction cost estimates are intended to support the construction bid process. Contractor will progress the 60%preliminary plan set following review by the permitting agencies, County, and larger stakeholder group including landowners. The development of the final plans, special provisions, and cost estimate will include the following tasks: • Develop Draft(90%) and Final (100%) Plans, Cost Estimate, and Special Provisions. • Draft(90%) and Final (100%)Basis of Design Report. • Proposed Conditions Hydraulic Models. All landowner outreach and stakeholder engagement associated with the final design is included in Task 5 Stakeholder Engagement and Community Outreach. Subtask 11.1. Develop Draft (90%) and Final (100%) Plans, Cost Estimate, and Special Provisions Contractor will use feedback from the County, permitters, landowners, and project stakeholders, to advance the design and associated construction plans to Final Design. Design modifications which are supported through analysis will be included in the final design submittal package. The construction cost estimate and Basis of Design report will also be updated and finalized as part of this task. Major design changes are not anticipated and are not included in this scope; however, an updated air photo of the final design area will be acquired prior to finalizing the final design. This air photo will be used to make any changes needed to the design to accommodate changes in the main stem channel location during the multi-year design process, like changing temporary access route and staging area locations. The final construction plans, cost estimate, and special provisions will be reviewed and certified by a Professional Engineer registered to practice in the state of Washington. Contractor will also prepare a stand-alone spreadsheet of construction materials and quantities (Bid Tab). Contractor will prepare construction special provisions that will follow WSDOT Standard Specifications and Special Provisions standard format. Construction special provisions prepared by Contractor will be limited to project-specific special provisions(Divisions 2-9); no Division 1 special provisions related to contracting are included as part of this scope of work. If project specific Division 1 special provisions are necessary, Contractor assumes they will be prepared by the County. Contractor will prepare a final, stamped plan set and final construction special provisions to be used for contractor bid documents as prepared by others. Subtask 11.2. Develop Draft(90%) and Final (100%) Basis of Design Report Contractor will update and'finalize the Basis of Design report prepared for the 60% designs to reflect the final design. This will include an update of the description of engineering assumptions Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3,PAO Approved 7/12/2021 Page 30 of 33 and calculations, function of each restoration element, and updated final hydraulic model output, if necessary. Subtask 11.3. Proposed Conditions Hydraulic Models During development of the draft final design, Contractor will update the proposed conditions hydraulic model of the project reach developed during preliminary design incorporating any changes to proposed restoration actions. The models will be used to evaluate any changes in hydraulic conditions as a result of the design modifications to ensure the project goals are met and flooding and erosion risks have not increased as a result. The suite of flows developed to characterize hydrology(Task 2)will be included as proposed condition models, as well as projected climate change flows,to ensure proposed elements are evaluated over a wide range of flow conditions. Task Assumptions • Permit agency and stakeholder comments on the Final 60%plans will be provided by County and incorporated into the Final Design. • County will be responsible for Division 1 of the Special Provisions. • The bid package will be compiled by others. • All review will be addressed between the 60%Design and submittal of the Final Design. • The level of effort for these deliverables has been set based on the assumption that review rounds do not exceed anticipated effort(1 round of review where noted) and no major design changes (revision of the number/location/type of structures) are requested. • Bidding and Construction Support is not included in this scope or fee estimate. Task Deliverables: • Draft and Final design drawings/plans, hydraulic model results, cost estimate (Final PS&E), Final Basis of Design Report,relevant appendices (hydraulic model results, stability calculations). Task 12. Project Management& Coordination Contractor will provide project management, coordination and support to the County for the duration of the project. Project management and coordination will be provided via brief 30-minute weekly (or 60-minute biweekly) check-in meetings with project management team, monthly invoices with project activities summarized, and regular correspondence between Contractor, project management team and County via email and phone to maintain open communication. Mike Ericsson, Contractor's project manager, and Ryan DeKnikker, Contractor's deputy project manager, will co-lead activities. Ryan will cover project scheduling, maintaining adherence to the scope of work,timelines, and due dates; Mike will coordinate with the County and within the Contractor team, and Tim Abbe will lead the team interaction with local stakeholders and subconsultants, with support from Ryan as a part of Task 5: Stakeholder Engagement and Community Outreach. Both Mike and Ryan will ensure adherence to data quality assurance and Hoh River Resiliency—Lindner Complex Reach Preliminary and Final Design Professional Services Agreement Template,JCPH,Version 3, PAO Approved 7/12/2021 Page 31 of 33 controls, with Tim Abbe leading the project QA/QC process. Ryan will work with Mike to produce summaries of work completed to accompany our monthly invoices for services completed. Task Assumptions ► The duration of the project will be 29 months, from January 2024 to May 2026. Task Deliverables: ► Monthly invoicing detailing work completed. ► Regularly scheduled check-in meetings with Contractor and County (weekly or bi-weekly).
