Off -channel habitat for threatened Chinook Salmon and other salmon is extremely limited in the Lower Green River, WRIA 9 has identified this project in the Salmon Habitat Plan. It was identified in the 2013 Surface Water Comprehensive Plan:. The City has recieved grant funds for project design, City st to expand the project site. Design wilt begin in 2024-25. af> is proposing to purchase adjacent property' This is a work in progress. The Green Infrastructure Program Proposal is intended, in part, to address maintenance needs for PW-initiated habitat restoration projects and helping to alleviate pressure on Parks, given resource constraints. Note that vegetation management maintenance needs decrease over time as planted vegetation matures. 3 years is considered a rule of thumb for plant establishment. This is one of the only opportunities,to create critically needed off -channel habitat on public lands along the tower Green River in Tukwila, There is potential to roughtytripte the project site by acquiring adjacent, vacant and largely (if not entirety) updevelopabte property.

Project Understanding The City of Tukwila (City) proposes the Nelsen Side Channel Salmon Habitat Project (Project) to accomplish three distinct goals: 1. Restore off -channel and high -flow -refuge habitat for juvenile Chinook salmon, consistent with WRIA 9 salmon recovery objectives 2. Maintain or reduce local flood risk, consistent with applicable floodplain management standards and adopted surface water design criteria 3. Improve public access consistent with City objectives The Project will reconnect the Lower Green River to its historical floodplain and re-establish riparian forest within a highly urbanized corridor, directly addressing limiting factors identified in the WRIA 9 Salmon Habitat Plan (2021 Update). Community benefits will be provided by developing safe, formally acquired public access routes that connect the shoreline with existing non -vehicular infrastructure in the area, while also accommodating necessary vehicular access for maintenance, operations, and emergency response. The project area (Figure 1) currently includes City -owned parcels and land recently acquired by the City from the Nelsen Family Trust. It is bordered by busy highways and private properties that include large hotels and is currently underutilized and prone to encampments. The site also contains a valuable stretch of Green River shoreline, a remnant of the historical river alignment and is immediately adjacent to key segments of existing pedestrian and cycling infrastructure that can be expanded upon to bring public access to the site and the Green River shoreline. The site also includes stormwater outfalls, utilities, and environmentally critical areas. The Project will include in -water, shoreline and upland restoration and improvements. The Project includes potential design of the westernmost parking bay at the Ramada Hotel and the potential footbridge connection pathway south of Ramada. The Project presents one of the most meaningful remaining opportunities in the Lower Green River to restore scarce juvenile Chinook rearing habitat, expand floodwater storage to reduce flood risk, and provide access to the river and greenspace in a highly urbanized environment. 13 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 2 Figure 1 - Project Area LEGEND Potential Shoreline Restoration Property Line • City of Tukwila 0 Nelsen Family Trust Property Q Extended Stay America Suites o Woodspring Suites Q Nelsen Family Residence Historical Trust Q Ramada by Wyndham Proposed Work Approach Anchor QEA will lead Phase 1 engineering, design, and outreach. We have included two subconsultants to support the effort: Psomas for upland survey and Holocene for geotechnical drilling. Anchor QEA has developed the following Scope of Work (SOW) to approach this complex project and identify feasible, constructable design solutions while concurrently achieving the three goals. The SOW is focused on Phase 1, which includes background information review, existing condition investigations, alternatives analysis, outreach and will develop the preliminary design (30%) package to be used in subsequent final design, permitting, and construction. The SOW includes the following tasks: • Task 1: Project Management • Task 2: Survey and Base Map • Task 3: Technical Investigations and Background Review • Task 4: Alternatives Analysis • Task 5: Outreach • Task 6: 30% Design 14 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 3 The SOW detailed fee proposal is included as Exhibit A. Subconsultant proposals are included as Exhibit B. 2. Scope of Services and Deliverables Task 1: Project Management This task includes management of the consultant's team and control of approved scope, schedule, and budget. Anchor QEA will develop, maintain and provide to the City a task -level schedule for the duration of the project. For the purposes of scoping, the negotiated fee assumes that project management will extend over an 11-month period, ending in December 2026. This task includes regular biweekly coordination meetings with the City. These coordination meetings will be virtual, 1-hour meetings between the City project manager (Joshua Hopkins), other City representatives as needed, and consultant team project manager (Arielle Farina -Williams). In addition to biweekly coordination meetings, this task includes City meetings at key project milestones. Meetings will take place at the following steps in the project: • Project kickoff meeting (1.5 hours, virtual, with three core consultant team staff) • Project milestone meetings (1 hour, virtual, with three core consultant team staff) — One meeting during Task 4 Alternatives Analysis — Two meetings during Task 6 (30% Design) Meeting agendas and notes will be prepared for the project kickoff and City milestone meetings. Meeting notes will be provided in a summary format that focuses on documenting key decisions and City comments. Deliverables • Meeting notes for project kickoff and City milestone meetings provided as summary emails • Budget status provided in monthly invoices by task (PDF file) • Project schedule developed in Microsoft Project (PDF file) Task 2: Survey and Base Mapping This task includes compiling a base map, including survey, existing bathymetry, and property data including boundary lines and easements. Anchor QEA's subconsultant, Psomas, will complete a topographic survey for upland project areas as shown in Figure 1 (see Exhibit A for subconsultant proposal). The survey will include ground features, such as extent of pavement, curbs, fences, trees, ditch features, and aboveground utilities. The survey will include utility locates to mark and survey underground utility locations. 15 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 4 The survey will include identifying property boundaries within the Project area. City property will be mapped using GIS data. Title reports and full boundary survey is not included for the City property boundary. A boundary survey and title reports will locate boundary lines for the private properties within the Project Area. Easement(s) through the private properties will be mapped. See Exhibit B for a full description of the survey scope. The City conducted a bathymetry survey of the in -water areas adjacent to the Project site in April 2025. In this task, the existing bathymetry survey will be compiled with the topographical survey to develop a comprehensive base map. Anchor QEA has not included effort to conduct additional bathymetry survey. Deliverables • Draft and Final Base Map (pdf and CAD files) Task 3: Technical Investigations and Background Review In this task, Anchor QEA will conduct technical investigations to inform alternatives analysis, design, and permitting. Anchor QEA will develop a memorandum summarizing the investigations as well as a review of background information. Subtask 3.1: Geotechnical Desktop Study Anchor QEA geotechnical engineers will review available subsurface data including data provided by the City, publicly available subsurface borings in the vicinity of the project area, and geologic maps. On the basis of this review, we will prepare a summary of anticipated subsurface conditions at the project site, highlight key geotechnical considerations for design development, describe seismic risks and mitigation strategies, and prepare a list of geotechnical data gaps as well as a recommended subsurface investigation strategy to be implemented under a future task. This task also includes a review and description of geologic critical areas that may be mapped within the project area. The work under this task will be documented in the Subtask 3.4 Background Review Summary Memorandum. Subtask 3.2: Habitat Investigation Our habitat restoration field team will complete a detailed assessment documenting landscape and habitat conditions to complement the other technical investigations. We will collect data on anthropogenic floodplain manipulation and armoring, riparian conditions and tree mapping, presence of large wood and instream habitat conditions, riverine floodplain engagement and sediment deposition, and off -channel restoration opportunities. Anchor QEA will also delineate existing wetlands and the ordinary high-water mark (OHWM) to assist with future permitting. The effort will require 2 days of field work for two staff and will include the following: 16 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 5 • Wetlands: Delineate wetlands within the Project area. Mark boundaries in the field using flagging and record using DGPS. Document findings, including wetland rating data sheets. • Wetland buffers: Characterize buffer conditions. Identify appropriate buffer extents for delineated wetlands and locate on site mapping. Characterize site conditions, including extent of native and invasive vegetation. Following the field work, Anchor QEA will document field conditions in a Wetland and OHWM Delineation Report that will support alternatives evaluation. The Wetland and OHWM Delineation Report will include assigning wetland functional ratings, wetland buffer width, and shoreline setback distances. The report will meet current state and federal wetland and OHWM delineation guidance and requirements. The report will incorporate City code for wetland shoreline buffer widths, river rating and 100-year FEMA flood mapping data. Subtask 3.3: Preliminary Hydraulic Analysis To inform a preliminary hydraulic assessment and support a site -specific sediment transport analysis, we will use the bathymetric and topographic data on the Green River compiled in Task 2. These data will be incorporated into the existing scale model developed by others to help with site evaluation. We will update the existing model geometry with the current topographic and bathymetric data to accurately represent the existing site conditions. We will use HEC-RAS 2D to model the site under a range of desired habitat flows up to 500-year flood conditions, where appropriate for alternatives screening to identify- existing hydraulic and geomorphic thresholds to inform alternatives development geared toward restoring natural processes. Coordinate local river gauge stages for habitat access and habitat type, and tidal fluctuations for sediment transport in and out of site. We will also conduct a drainage analysis and review of drainage requirements to characterize existing project site runoff and outfall locations. The primary use of the hydraulic model will be for alternatives evaluation and the development of the preferred alternative. The model will also provide key design information on grades, elevations, and widths for channel and other site features as well as help inform permit related data and information. Reporting documentation will include a summary narrative including: review of the river reach geomorphic assessment, tidal signal and implications for sediment transport, potential for design flood storage, scour and habitat access, and habitat type. Reporting will include at least one figure showing the river stage graph for a representative year with elevation markings to communicate how river states impact and relate to the site. Subtask 3.4: Background Review Summary Memorandum Anchor QEA will review background information provided by the City (on a City SharePoint library) and information that is publicly available. Known information includes: 17 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 6 • WSDOT as-builts and record documents for 405 • As-builts and record documents for adjacent hotels and properties • King County documents relevant to Green River and flood control including FEMA maps • WSDOT geotechnical data • Cultural Resources Review • City GIS data for critical areas, utilities, environmental data, etc • City Comprehensive Plan • Southcenter Subarea plan • Parks, Recreation and Open Space Plan • Shoreline Master Program • WRIA 9 Habitat Plan • Lower Green River Corridor Flood Hazard Management Plan PEIS This subtask will include developing a site analysis graphic annotating the Base Map developed in task 2 with available information including: existing access routes, existing habitat areas, existing road prism locations and site features, existing stormwater features and drainage patterns, historical features, and any potential relevant cultural resources (where/when applicable). This graphic will include relevant site observations and client and stakeholder input. The site analysis graphic will highlight key opportunities and constraints (such as needed easement need to formalize access routes) and inform the alternatives analysis in Task 4 and the outreach described in Task 5. Deliverables • Draft and final background review summary memorandum with sections summarizing geotechnical, habitat and hydraulic analyses (word and pdf files) • Draft and final site analysis graphic (pdf file) • Draft and final Wetland and OHWM Delineation Report Task 4: Alternatives Analysis Subtask 4.1: Project Goals and Design Evaluation Criteria In this subtask, Anchor QEA will also draft Project goals. Anchor QEA will then document design evaluation criteria based on the identified Project goals and the work completed in Task 3. The design evaluation criteria will be used to evaluate the alternatives and guide the development of the preferred alternative. Project goals, evaluation criteria, and relative weighting shall be subject to City review, revision, and final approval prior to application. 18 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 7 Subtask 4.2: Alternatives Development Anchor QEA will develop three conceptual design alternatives which may include variations of key elements, that consider the existing conditions, sustainability, Project goals, and work completed in Task 3. The design alternatives will propose different approaches to restoring the habitat, reducing local flood risk, and improving public access in a manner subordinate to and compatible with habitat restoration and flood -risk -reduction objectives. The conceptual alternatives will be shown in simple, basic scaled plan and section drawings over the basemap. The plan and section drawings will be color rendered in a basic, consistent way to provide clarity of communication. A conceptual rough order -of -magnitude (ROM) opinion of probable construction cost (OPCC) will be developed for each of the alternatives to assist in the alternatives analysis and is intended for planning and comparative purposes only. Subtask 4.3: Alternatives Analysis Anchor QEA will conduct initial simulations in HEC-RAS 2D, modifying the existing conditions preliminary model developed in Task 3.3 to best represent each alternative. Hydraulics and sediment transport patterns will be analyzed for project sustainability and habitat benefits as a component of the evaluation criteria. We will then analyze the alternatives based on the design evaluation criteria generated in subtask 4.1. Anchor QEA will develop a summary of the alternatives evaluation and analysis in the form of a summary matrix showing the design evaluation criteria and rankings with the intention of choosing one of the conceptual design alternatives as the preferred alternative. Example design evaluation criteria will include: • Flood Risk Criteria — Flood storage effects — Water surface elevation changes — Implications for levees, infrastructure, and adjacent properties Consistency with applicable floodplain management policies and system -wide flood - risk frameworks (e.g., KC SWIF) • Public Access Feasibility & Site Maintenance Criteria If one conceptual design alternative is not determined to be the preferred alternative, the desired elements that scored well in the alternatives analysis will be summarized to inform the next step of project design (task 6). Reporting will document reasoning for preferred alternatives selection and why other alternatives were not selected. Subtask 4.4: Alternatives Analysis Report Anchor QEA will develop the Alternatives Analysis Report. This report will serve as the foundation for design and permitting work and will include: 19 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 8 • Project Goals • Design Evaluation Criteria • Narrative review of Alternatives Considered with ROM Costs • Evaluation Summary Matrix • Narrative review of City Decisions and Preferred Alternative with ROM Costs • Preliminary permit pathway for preferred alternative • Data gaps City Review and Authorization to Proceed Completion of Task 4 shall constitute a formal decision point. Following City review and acceptance of the Alternatives Analysis deliverables, the City will determine whether to: a. authorize advancement of the Preferred Alternative into Task 6 (30% Design), b. direct refinement of alternatives, or c. pause or modify the scope. Deliverables • Draft Project Goals and Design Evaluation Criteria (word file) • Draft and Final Concept Design Alternatives (pdf files) • Draft and Final ROM Costs for Each Alternative (pdf files) • Draft Alternatives Analysis Summary Matrix (pdf file) • Draft and Final Alternatives Analysis Report (word and pdf files) Task 5: Outreach Subtask 5.1: Technical Stakeholder The Project will engage with a Technical Stakeholder team including: King County Rivers and Floodplain Staff (KC Flood Control District Service Provider), WRIA 9 and King County Technical Science Staff (fisheries ecologist and habitat and landscape/aquatic processes), Muckleshoot Indian Tribe (MIT), Duwamish Tribe (DT), and WDFW. Anchor QEA will participate in up to five Technical Stakeholder meetings. One may be on site (2 hours in length with 1 hour of travel time), and three Anchor QEA staff will attend. Four will be virtual (1.5 hour in length) and three Anchor QEA staff will attend to cover sediment and habitat technical discussions. The City will lead meeting logistics and coordination, including providing relevant documents to the Technical Stakeholder team prior to meeting. The meetings will take place at key milestones: • Kickoff (prior to alternative design) 20 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 9 • Background data review (prior to alternative design) • Flood protection meeting (KC Rivers and Floodplain Staff, WSDOT) • During Alternatives Analysis to review alternative designs • Prior to finalizing the preferred alternative design Subtask 5.2: Real Estate Coordination The Project will engage with the City's selected real estate consultant (Commonstreet Consulting) and the adjacent property owner (3 hotels and the Nelsen Family Trust). Anchor QEA will participate in up to four virtual meetings. Each will be 1 hour in length and two Anchor QEA staff will attend. The City will lead meeting logistics and coordination. The meetings will occur prior to starting Task 4 (Alternatives Analysis). Coordination with the City's real estate consultant will be integrated into this work to confirm that all easement options for access routes proposed are viable. The real estate consultant will be asked to join regularly scheduled PM check in meetings as determined by the City in partnership with Anchor QEA. Subtask 5.3: Permit Agency Anchor QEA will attend one virtual meeting with applicable City permit review team members to review City permit requirements. The meeting will last 1.5 hours and two Anchor QEA staff will attend. This will occur after a preliminary preferred alternative is identified but before it is finalized. Anchor QEA will engage USACE staff to determine if Section 408 is required for any project alternatives. This will be conducted with emails and phone calls and up to one meeting attended by two Anchor QEA staff. Subtask 5.4: WSDOT Outreach Anchor QEA will attend one virtual meeting with WSDOT early in the project. Two Anchor QEA staff will attend. Subtask 5.5: Public Meeting Anchor QEA will attend one public meeting with the community. In advance of the meeting, Anchor QEA will work with City staff to develop a multi-lingual online survey tool. The City will lead the development of the tool and Anchor QEA will provide project -specific technical information. The City will advertise the survey in the e-Hazelnut and other City -led media efforts. Anchor QEA will develop and lead a short presentation. Anchor QEA will bring up to three rendered boards showing the existing site, site analysis and preliminary preferred alternative. The meeting will be in person and last 2 hours. Two Anchor QEA staff will attend. Anchor QEA will compile notes and input from the meeting participants. 21 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 10 Deliverables • Agendas and meeting notes for outreach meetings (emails) • Draft and final presentation for public meeting (Powerpoint file) • Plotted boards for public meeting • Notes from public meeting (word file) • Compile all documentation into the Alternatives Analysis Report Public engagement is intended to inform City decision -making and does not obligate incorporation of public preferences where inconsistent with project goals, technical feasibility, regulatory requirements, or funding constraints. Task 6: 30% Design Task 6 shall commence only upon written authorization from the City following acceptance of Task 4 deliverables and confirmation of the Preferred Alternative. Subtask 6.1: Engineering Analysis 6.1.1 Hydraulic analysis At the 30% design stage, the model will be re -run to optimize the design with respect to meeting project objectives. We will also evaluate the stability of any proposed large wood or other design features. In addition, we will optimize key design parameters, such as grades, elevations, and widths for channel and other site features. Finally, the model findings will be used to extract key permit related data and information. 6.1.2 Geotechnical Investigation Anchor QEA will conduct a subsurface geotechnical investigation to address data gaps and inform the geotechnical design of the selected alternative from Task 4. Our scope assumes we would advance up to 4 borings using a track -mounted mud rotary drill rig. One boring would be advanced to 100 feet below ground surface to support seismic risk evaluations. The remaining 3 borings are assumed to be advanced to 50 feet below ground surface. A field geologist will create a log of subsurface conditions and collect samples from discrete depth intervals. Representative field samples will be submitted to a geotechnical test laboratory for further engineering classification. Our scope assumes the following laboratory testing program: • Moisture content per ASTM D2216 — up to 66 samples • Grain size distribution (with hydrometer) per ASTM D6913/D7928 — up to 8 samples • Atterberg limits per ASTM D4318 — up to 8 samples • One-dimensional Consolidation testing per ASTM D2435 — up to 4 samples 22 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 11 Note our geotechnical engineers may recommend to modify this investigation scope after the Data Gaps review and based on the project elements included in the selected alternative. Anchor QEA will coordinate with the City if scope modifications are recommended. We have assumed no environmental sampling for our subsurface geotechnical investigation. If the City suspects contaminants may be present, Anchor QEA can provide a scope amendment to add subsurface chemical testing in coordination with the geotechnical sampling program. Following the geotechnical field investigation, Anchor QEA geotechnical engineers will prepare recommendations to support the 30% Design. These recommendations will be documented in the Subtask 6.4 30% Basis of Design Report. We assume the following geotechnical engineering analysis would be needed to support the 30% Design: • Summary of subsurface conditions • Recommendations for Earthwork • Recommendations for Levee Design and Construction • Seismic design input including liquefaction assessment, seismic slope stability, and recommendations for post -earthquake contingency actions. Our scope does not include a site -specific seismic hazard analysis. If such an analysis is recommended, this will be documented as a data gap to be addressed during a subsequent design stage. Our scope does not include foundation design recommendations for structures. If structures are included in the selected alternative, we will revisit our assumptions to evaluate whether a scope amendment is recommended or if these recommendations can be completed under our existing authorized budget. Finally, based on subsurface variability encountered during the subsurface investigation, Anchor QEA geotechnical engineers may recommend supplemental geotechnical data be collected in a future phase of design to reduce uncertainty and address related data gaps. Subtask 6.2: 30% Design Drawings Based on the preferred alternative, identified Task 4, Anchor QEA will prepare 30% Design drawings. The 30% Design drawings will be prepared using AutoCAD Civil3D software. The list below, while subject to change, provides a basis for estimating the level of effort that will be required to complete the drawings. Each set of plan drawings will be provided on two sheets at 20-foot scale, unless otherwise indicated. The following is a general sheet list for 30% Design development: • Existing condition plans with river gauges • Composite site plan noting the proposed Project key design features i.e. off -channel creation areas, habitat areas, public access routes, with the base survey map underlay (one sheet at 40- foot scale) • Access and staging plan (one sheet at 40-foot scale) 23 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 12 • Demolition plans • Grading and drainage plans • Construction materials plans with river stages • Grading and material sections (two sheets at 10-foot scale; no exaggeration) with river stages • Planting plans • Plant schedule (one sheet) Subtask 6.3: 30% Design Opinion of Probable Construction Cost Anchor QEA will develop an Opinion of Probable Construction Cost (OPCC) for the design shown on the 30% Design drawings. Anchor QEA will prepare an OPCC, based on estimated quantities and unit costs, to document the expected implementation cost. The design development OPCC will be assembled in a format consistent with the CSI MasterFormat. Subtask 6.4: 30% Design Basis of Design Report Anchor QEA will draft a Basis of Design (BOD) report. The BOD will be a living document during design and permitting efforts. At 30% Design, it will include: • Specification Outline (following CSI MasterFormat) • Geotechnical Investigation results • Hydraulic Analysis results • Update Design Criteria • Identified Data Gaps Deliverables • 30% drawings (pdf file) • 30% OPCC (pdf file) • 30% Design Basis of Design Report (word file) 3. Assumptions • Meetings in addition to those described in this SOW are not included and will be considered additional work. • Outreach and engagement meetings will rely on materials in other tasks to produce outreach materials. • The City will determine who is invited to community meetings, provide all meeting invitations, and coordinate meeting logistics, including securing meeting rooms and ensuring that audio- visual equipment is available and in working order. • Community meetings will occur in the evening and will be a conventional format with a presentation followed by a question -and -answer session. 24 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 13 • The City will determine if a project website is desired and, if so, will provide project updates on a City -led online platform (such as the City's website). This will include posting community meeting presentations and community survey results. • The City will lead outreach with all Tribes. • Travel time will be billed to the City. Travel time from Seattle to the City is estimated at 1 hour round trip. • Alternatives will be developed within the project areas identified in Figures 1 and 2. If the project boundaries expand, Anchor QEA will discuss with the City which level of evaluation and/or design work can be conducted within those additional areas within the scope and fee negotiated for this work. • Environmental and construction permit packages development and submittal is not included in Phase 1. • Anchor QEA will engage with King County and USACE to determine whether Section 408 is required for any alternative. If this is determined to be required, this will be scoped as part of permitting in Phase 2. • The survey will include title reports and boundary survey for the private parcels in the Project area. The survey will only include mapping GIS boundaries for the City owned parcels. • Bathymetry survey is not included. The base map will compile the City -provided April 2025 bathymetric survey data. • Anchor QEA will utilize the City -provided existing hydraulic model. • The City's 2025-2030 Capital Improvement Program (CIP) currently identifies a planning -level construction budget of approximately $4.2 million for the Project, assuming construction in 2027. This figure represents an early -phase, non -escalated estimate developed for programming purposes and does not reflect detailed site -specific constraints, market escalation, or outcomes of alternatives analysis. Phase I design and alternatives evaluation are intended to inform refined cost understanding, funding strategy, and future budget alignment consistent with project goals and precedent outcomes from comparable projects. • An OPCC will be developed to reflect the level of design (conceptual and 30% Design) and will include a contingency markup appropriate to this stage of design. • The SOW does not include time for developing grant applications. • A management reserve estimate is noted in the fee estimate in case additional work is identified and agreed upon. Anchor QEA will not utilize the management reserve unless directed in writing by the City. 4. Budget See Exhibit A for the detailed fee proposal. 25 January 29, 2026 Nelsen Side Channel Restoration Project — Phase 1 Page 14 5. Schedule Work will begin immediately following Notice to Proceed (NTP). Assuming NTP is provided by February 15, Anchor QEA will bill a minimum of $100,000 by March 31, 2026.
