BACKGROUND Riverton Creek discharges into the Duwamish River through two pipes originally installed as part of construction of SR -599. Each of these pipes was fitted with a flap gate to prevent river water from flooding adjacent property. To improve fish access to Riverton Creek, the City has proposed a fish habitat project that will remove the pipes and flap gates in order to create an open water connection to the river. The City received grants from the Salmon Recovery Funding Board for $42,500 and from the People for Puget Sound for $30,000 to perform a limited feasibility analysis conceming the potential for flooding and perform design work. ANALYSIS The current Consultant Roster was reviewed and CH2M Hill, Berger /Abam, and Rosewater Engineering were short- listed to conduct this feasibility analysis and design work. Berger /Abam and Rosewater Engineering submitted proposals and both firms were interviewed. Berger /Abam scored highest in meeting the goals of the project. Berger /Abam designed the S. 180 St. Grade Separation project and staff was satisfied with this design work. It is recommended that Berger /Abam perform preliminary design work on the Riverton Creek Flap Gate Removal project for a fee of $121,842.00.

These culverts both have flap gates, although one of the flap gates has been missing for about ten years. This project will remove these culverts and flap gates along with the surrounding fill. The desired outcomes of removing these culverts are: Create a more natural open discharge of the Creek into the Duwamish Remove the fish barriers caused by the perched culverts and flap gates Improve riparian plantings along the last 650 feet of Riverton Creek Improve salmon rearing and resting habitat within the last 650 feet of the Creek Due to current funding limitations, the preliminary engineering for this project will be broken into two phases. This initial contract (Phase 1) will focus on doing as much as possible to help the City sell the project to the salmon habitat grant agencies. The concentration is on developing a good habitat restoration plan, a 75% set of plans, a 75% cost estimate, and laying the groundwork with the business park, WSDOT, the funding partners, and King County Parks. Following this course does involve some risk that the design will proceed ahead of obtaining environmental approvals that have a small chance of terminating the project if they can't be obtained or the required mitigation is too expensive. However, this risk appears to be small and if the limited funds are spent on environmental studies at this time, the project itself wouldn't be defined well enough to generate support for future funding. Phase 2 will complete the geotechnical studies, environmental site assessment, environmental studies, permits, final design, ROW and easement acquisition, and construction contract documents. The schedule will be determined in coordination with the City with consideration for milestones stipulated by the funding grants. At this time, it does not appear that the milestones for the SRFB grant or the People for Puget Sound grant can be met without amendments to the grants. For purposes of the fee estimate, this Phase 1 scope is assumed to be completed within five months of notice to proceed. Exhibit A Scope of Work for Engineering Services for Phase 1 of BERGER/ABAM, FPPWT -09 -202 the Riverton Creek Flap Gate Removal Project February 2009 A -2 PROJECT PARAMETERS The following list is included to confirm the understanding between the City and the Consultant and will be used to guide the work. These items are general in nature; assumptions specific to particular tasks are listed under those tasks. 1. Throughout this scope of work, it is understood that the City will provide the Consultant with one set of consolidated review comments for each draft review round. The Consultant will then respond to the comments and incorporate the agreed -upon resolution into the final document(s). 2. Based on the plans available prior to completion of the survey in this scope, it is not anticipated that any utilities will be affected. If utilities are affected, it is assumed the utility owners will prepare utility relocation and reconstruction plans for gas, telephone, electricity, and cable as needed. If needed, the Consultant will prepare water and sewer relocation and reconstruction plans as a supplemental service. 3. The Consultant will provide the City with all drawings, technical special provisions, amendments to the standard specifications, and the bid item list (bid proposal). The City will use these items to prepare the bid and contract documents using the City's typical contract manual boilerplate. PHASE 1- 75% CONTRACT DOCUMENTS Task 100 Project Management and Administration Invoices, Progress Reports, Subconsultant Coordination, and Record Keeping The Consultant will perform project administration and management tasks as follows. 1. Prepare and submit monthly invoices and progress reports, including a tabulation of hours expended broken down by each major task. 2. Perform on -going subconsultant liaison. 3. Maintain all contract required documentation. Deliverables 1. Monthly invoices and progress reports City Coordination Meetings The Consultant will attend periodic coordination meetings at the City. These meetings will be scheduled as needed, and it is assumed there will be two during Phase 1. It is assumed two members of the design team will attend each meeting. Deliverables 1. Meeting minutes for each meeting Exhibit A Scope of Work for Engineering Services for Phase 1 of BERGER /ABAM, FPPWT -09 -202 the Riverton Creek Flap Gate Removal Project February 2009 A -3 Task 110 Quality Assurance and Quality Control (QA /QC) The Consultant will provide QA /QC for all design work in accordance with the Consultant's QA /QC standards. Specifically, the project manager and /or project engineer will review all submittals (both in -house work and subconsultant work) before they are submitted to the City. Any required changes will be made prior to submittal to the City. Deliverables 1. QA /QC documentation for all design work will be made available to the City upon request. Task 200 Topographic and Boundary Survey The Consultant will provide topographic mapping and boundary survey within limits as indicated on the attached aerial photo. Mapping will be performed to provide a 1 =20' topographic base map and digital terrain model (DTM) in AutoCAD foiutat of the project within the limits described above. The base map will include signs, trees, curbs, sidewalks, utility poles, signal poles and other surface features within the mapping area as described above. One -foot contours will be generated from the DTM. Adjacent ROW and Property lines will be shown based on WSDOT ROW plans and available survey data for adjacent parcel. The consultant will acquire a right -of -entry agreement for this work from the business park owner. Assumptions Current Title Reports will be provided by the City of Tukwila for all parcels adjacent to the project. It is anticipated that there is only one private parcel that would have a title report. The City of Tukwila will provide documents (as- builts) for City owned utilities. Elevations will be referenced to NAVD 1988 datum. Horizontal control will be determined by NAD 83/91 (State Plane Coordinates North Zone) Deliverables 1. Right -of -Entry agreement 2. AutoCad Basemap with DTM Task 210 Preliminary Sensitive Areas Report The consultant will evaluate the wetlands and aquatic resources within the project area and complete a preliminary sensitive areas report as required by the City. The assessment will include the determination of the approximate boundaries of the wetlands within the project area and the existing conditions of the wetlands, streams, and associated buffers. Wetland and stream locations will be recorded with a Trimble Geo -XT GPS unit for future project use. The information gathered during the preliminary sensitive areas assessment will be necessary to accurately determine the appropriate fish and wildlife enhancements. The report will provide the following information: e Documentation of the site's baseline conditions with photographs ra Determination of wetland boundaries within plus /minus 3 feet Recording of different vegetation classes Recording of different hydrologic regimes Exhibit A Scope of Work for Engineering Services for Phase 1 of BERGER /ABAM, FPPWT -09 -202 the Riverton Creek Flap Gate Removal Project February 2009 A-4 Assessment of appropriate wetland and stream classifications and buffers under local, state, and federal jurisdictions As direct wetland impacts are not likely to occur as part of the project, it is anticipated that a complete wetland delineation report and supporting materials will not be required to obtain the necessary permits. Deliverables 1. Preliminary sensitive areas report 2. Graphics detailing locations of wetlands /streams 3. Digital files of wetland and stream boundaries Task 300 Flood Prevention Feasibility Study A feasibility study will be performed by the Consultant to verify that the removal of the flap gates will not increase upstream flooding. Since one flap gate is already missing, it is assumed that the current condition does not differ from the after construction condition in terms of backwater flooding of Riverton Creek from the Duwamish 100 year flood. Therefore, this study will actually determine if 100 year flood levels on the Duwamish cause backwater flooding of private properties adjacent to Riverton Creek without the flap gate(s). If these Duwamish floods do not cause this flooding, then the project can proceed. If they do, then the private properties are already at risk due to the one removed flap gate, and that flap gate may need to be reinstalled and the project abandoned. It is assumed that the Consultant will use existing data and site observations to determine flooding conditions and that no hydraulic modeling/analysis will be done. Deliverables 1. Flood prevention feasibility study technical memorandum Task 310 Wall Strengthening Feasibility Study The goal of this project is to restore the lower reaches of Riverton Creek to a more natural, predevelopment condition. This includes removal of twin 48" culverts, flap gates, and fill as well as the enhancement of salmon habitat. The Creek is confined between Tukwila International Blvd. ('1113) on one side and a commercial development parking lot on the other which means this project will likely require acquisition of some of the parking lot or removal of fill outside the sheet pile wall supporting TIB. It is assumed for this scope that acquiring part of the parking lot will not be feasibile, therefore removal of fill outside the wall will be required. Based on as builts for 1113, it appears likely that this wall will need to be strengthened with tiebacks in order to remove the fill outside the wall and restore an open stream channel. It is assumed that all the preliminary engineering for this task will be based on the information available from the as- builts for the sheet pile wall and adjacent bridge and on the geotechnical report for the design of that wall and bridge. The consultant will prepare a preliminary design memorandum discussing the project impacts on the bridge approach embankment and sheet Exhibit A Scope of Work for Engineering Services for Phase 1 of BERGER/ABAM, FPPWT -09 -202 the Riverton Creek Flap Gate Removal Project February 2009 A -5 pile wall to include design earth pressures and the design recommendations for additional ground anchors. The assumptions used in this task will be confirmed by the borings proposed for phase 2. Deliverables 1. Technical memorandum of the preliminary design of any required strengthening of the existing sheet pile wall. Task 400 Business Park Owner/Tenant Coordination Following completion of the boundary survey, the design team and City will meet with the owner, and possibly some tenants, of the business park adjacent to the lower reaches of the Creek. This step will be important to determine what the willingness of the owner /tenants is for conveying ROW and /or easements that may be needed for removal of fill, clearing and new planting of the Creek banks, and construction access. It is assumed there will be one meeting. One member of the design team will attend the meeting. Deliverables 1. Meeting minutes Task 410 WSDOT Coordination A portion of the project area is adjacent to WSDOT ROW for an off ramp of State Route 599. Following coordination with the business park, the design team and City will meet with WSDOT to outline the project and discuss any issues WSDOT may be concerned about (primarily expected to be undermining of the ramp and clear zone obstacles). It is assumed there will be one meeting early on attended by one member of the design team. Deliverables 1. Meeting minutes Task 420 Funding Partner Coordination The design team and City will meet with the SRFB and People for Puget Sound. The meeting will be to summarize the results up to that point and seek any input the two agencies might have on the direction of the project. It is assumed that one member of the design team will attend the meeting and that both agencies will attend the meeting together. Deliverables 1. Meeting minutes Task 500 Stream Restoration Design The consultant will prepare a stream and riparian habitat restoration plan. The plan will consist of a narrative detailing the existing conditions of the site, potential wildlife habitat utilization, and the proposed enhancements, expected results, and monitoring and maintenance details. This project narrative will accompany the necessary permit applications. Exhibit A Scope of Work for Engineering Services for Phase 1 of BERGERJABAM, FPPWT -09 -202 the Riverton Creek Flap Gate Removal Project February 2009 A -6 The consultant will also design a series of comprehensive enhancement measures designed to maximize the enhancement of fish and wildlife habitat by the most cost effective means. Deliverables 1. Riparian habitat restoration plan Task 510 Green River Trail Detour Design and Coordination It is assumed that the Green River Trail will have to be closed at the project site for at least a month. Since this is a nearly 20 mile long trail and closing the entire trail is not an option, it will be necessary to provide a trail detour for the safety of users trying to bypass the closed section. The consultant will work with the City and King County Parks to decide on the shortest and safest detour. Deliverables 1. Trail detour design memorandum Task 600 75% Construction Contract Plans The consultant will prepare the following 22" x 34" full size plans for the project: Title sheet with vicinity map and sheet index Construction staging sheet Green River Trail detour plan sheet (scale to be determined) Green River Trail detour signing sheet Site preparation and TESC plan sheets (2 sheets 1 =20') Site preparation and TESC details and notes sheet Grading plan sheet (1 =10') Grading trail restoration, and bank armoring details and sections sheets (2 sheets) Planting and stream restoration plan sheets (2 sheets 1 =20') Planting and stream restoration detail sheet Sheet pile wall strengthening plan, sections, and details Trail bridge foundation plan and pile details and sections sheet Trail bridge abutment plan, details, and sections sheet Trails bridge superstructure and bearing details sheets (2 sheets, see task 600) *If a short spur trail, rest stop, interpretive site, etc. is included, the grading plans will cover the grading and surfacing within this scope. Any improvements like benches, tables, signs, etc. are not included in this scope, but could be added by supplement at a later date. This scope assumes that any treatment of the parking lot water will be done with a vegetative buffer between the stream bank and parking lot. This scope does not include the addition of drainage structures or curbs in the parking lot, but they could be added by supplement at a later date. Deliverables 1. Half size review set of 75% construction contract plans Exhibit A Scope of Work for Engineering Services for Phase 1 of the Riverton Creek Flap Gate Removal Project A -7 BERGER/ABAM, FPPWT -09 -202 February 2009 Task 610 Construction Contract Cost Estimate The consultant will prepare estimates of the project costs including construction costs, contingencies, inflation, design engineering, construction engineering, City administration, and ROW. The cost estimate will include estimated fair market value for the temporary construction easement and the permanent partial fee simple real property rights. A Parcel Funding Estimate worksheet similar to WSDOT's Local Agency Guidelines 25.143 will be completed to estimate the probable costs for the real property rights needed. Deliverables 1.
