The project will replace the existing stormwater overflow from the Monroe Avenue basin, which currently flows into a large infiltrating pit on a private property at 301 Monroe Avenue NE, owned by Segale Properties, LLC (Segale Properties). As selected in the project’s Phase 1 Alternatives Analysis, Phase II of this project will design new infiltration chambers and a water quality facility at the same site. During the Alternatives Analysis Phase I of the project, Otak presented six alternative solutions to provide flow control and treatment of stormwater from the 245-acre Monroe Avenue subbasin in Renton’s Lower Cedar River Basin. The alternative solutions centered around various conveyance and regional stormwater facility concepts, and is documented in an Alternatives Analysis Memorandum, dated August 11, 2020. On July 7, 2020, Alternative One was selected as Renton’s preferred solution. It includes Stormtech Chambers Infiltration at Upper Balch Pit with Surface Water Quality Treatment, and stormwater treatment. A key deciding factor of this treatment option is that it includes a series of treatment steps and design solutions that will create a progressive and robust treatment that will increase the lifespan of the solution. The selected alternative includes conveyance improvements to and from the site. The planned project schedule is to be complete within 8 months. A detailed schedule will be prepared and updated as needed as part of the project management task. PROJECT SCOPE The following scope of services for Phase II includes the planning and preliminary design of the selected alternative. 1. Project Management 1.1. Project Administration Otak will prepare and update a project work plan that incorporates and presents the planned and actual project schedule, staffing plan, budget expenditures, and percent of tasks completed on a quarterly basis, or more if needed.

Written responses to the consolidated and screened list of comments from stakeholders. 3. Survey and Basemapping 3.1. Topographic Surveying and Mapping Otak will create a topographic basemap in AutoCAD format appropriate for final design. The survey data previously collected for the fill operations will be integrated into the topographic map. The mapped areas include the following: a) Approximately 2,500 linear feet of roadway including utilities and storm drainage infrastructure (Monroe and Jefferson) where approximately 1000 linear feet of that survey is of Jefferson adjacent to the Segale Property, and the rest is Monroe between the intersections of 4th and 2nd; b) Approximately 1,500 linear feet of storm drain as-builts (2nd & 4th); c) and, Approximately six acres of adjacent filled areas for stormwater facilities (Segale property). Otak will field survey existing surface features including topography breaks, pavement and other hardscape, channelization and signing, significant trees and other landscaping, fences, invert elevations and pipe dimensions of existing storm drainage. Storm drainage and other utilities will be surveyed to the first structure or fitting outside of the area to be surveyed and mapped. A utility locate service will be retained to mark underground utilities. Utility as-built records will be researched and collected. Utilities evident on the surface and as located with paint marks by a utility locate service, will be surveyed. Base mapping in AutoCAD format showing the features outlined above; contours will be shown at one-foot contour intervals. Otak will reference survey and mapping for this project to the City of Renton horizontal and vertical datum. The City will be responsible for obtaining rights-of-entry on all affected parcels, which is expected to be limited to the Segale property. Otak will support this by identifying parcels where permission rights are needed. 3.2. Right-of-Way and Parcel Boundary Resolution A search will be made for property corners and right-of-way monuments in the project area. Any found property corners and monuments will be surveyed and protected until all survey information has been gathered as designated in this Task 3. Together with information obtained through field survey, research, and existing right-of-way information available through the City and King County, the right-of-way margins will be resolved and mapped with dimensions of record. The Segale parcel(s) will be resolved to a level of certainty appropriate for preparation of legal documents containing legal descriptions such as easements or right-of- way dedications. Adjoining property lines other than those listed above will be based on existing GIS data or information shown on tax assessor maps, and published Tax Assessor legal descriptions for exhibit purposes. 3.3. Easement Exhibits/Legal Descriptions Legal descriptions and exhibits shall be prepared as supporting documents for easements and/or right-of-way acquisitions. These properties will require a level of resolution based on field survey, vesting deeds, and other record information. We assume that up to two legal descriptions and exhibits shall be required for this project. Title reports for these parcels shall be supplied by the City. Assumptions for Task 3: 1. Renton will obtain all rights of entry needed to complete the design level survey and base mapping. Otak will assist the City by identifying all parcels that Otak will need access to.

Renton will lead all negotiations in obtaining temporary and permanent easements. Otak will assist the City by defining the easements needed for this design, construction, and maintenance of the facilities in this project. 3. Otak will return to the site immediately prior to completion of 30% plans to map the current state of the fill area to allow for updated volume calculations. Deliverables for Task 3: 1. Base mapping in AutoCAD format showing topography, utilities, and existing site features as described above. 2. Parcel and boundary/right-of-way mapping as described above. 3. Easement exhibits/legal descriptions as described above. 4. Aspect’s Geotechnical and Hydrogeological Services The following proposed scope of services has been developed by Aspect to assist the Otak team during the detailed design of the stormwater system. This scope of services includes borehole infiltration test wells, performing infiltration well design modifications, conducting confirmation testing, mounding analyses, reporting and construction support. Based on Aspect’s discussion with Otak and the general subsurface uniformity encountered in previous borings and PIT completed by Aspect, see Table 1 for overview of the Phase I Geotechnical Investigation work completed (Investigation Levels 1-3), Aspect will provide design support for a 2.1-acre infiltration facility in the northwest portion of the Upper Balch Pit. Aspect’s geotechnical and hydrogeological approach in this task is a slight deviation from the City of Renton stormwater standard requirements, which indicate: (1) PITs are normally used to determine design infiltration rates; and, (2) a minimum of one infiltration test is required for each infiltration facility, with additional tests required for a large facility as is planned for the project. In the case of the Upper Balch Pit, the thickness and extent of recent fill which overlies the native outwash receptor unit, will make PITs extremely challenging locally. Therefore, in this task, Aspect will use borehole infiltration tests (and in later phases of work PITs), as specified in the following five sub-tasks: Scope of Services (continued) K:\Project\33200\33201A\Contract\Supplement 2 - Monroe Ave NE Storm System Improvements - Phase 2 (Design and CM)\Amendment 2\20_1113\33201 Monroe Ave NE SOW 11.13.2020.docx City of Renton 7 Monroe Avenue NE Storm System Improvements Otak Table 1: Levels of Field Conditions Inventory Level Hydrology Hydraulics Geotechnical Level 1 Qualitative Desktop Basin Characterization Completed in Phase I of project Desktop (GIS and studies by other) review and analysis.

Aspect Coordination with Renton, Otak and Stakeholders 1. Review the existing stormwater plan and site geologic and hydrogeologic data for the proposed testing locations and develop preliminary PIT and infiltration test well locations, design details and approximate testing flow rates to guide planning, installation, and testing work. 2. Develop an infiltration well installation work plan detailing the drilling, well installation, and confirmation testing procedures and the criteria that will be used. 3. Coordinate project administration and work activities with Otak, the City, Segale, and drilling and excavation subcontractors. 4.2. 30% Infiltration Investigation The infiltration investigation includes borehole infiltration tests/wells where the thickness of fill makes a PIT infeasible. If a substantial amount of the recently placed fill could be removed from the proposed infiltration facility footprint more PIT could be completed, and the number of borehole infiltration tests/wells could be reduced accordingly, providing savings to the project. However, this proposal is based on site conditions as they presently exist. 1. Well and Piezometer Installation a) Monitoring Wells Monitoring wells will be constructed at up to 6 locations within the proposed infiltration facility. Aspect will coordinate with Otak and Segale staff regarding areas where fill thicknesses are likely to be greater than 20 feet thick to where borings will provide efficiency for data collection compared to PITs requiring extensive excavation. The scope and budget assume one to two wells installed per day based on our previous borings south of the Upper Balch Pit. The subtasks include: 1) Coordinate and contract with a driller to install infiltration test wells under Aspect’s direction. 2) Secure, test, and calibrate groundwater monitoring equipment. 3) Observe infiltration well drilling and installation. Infiltration test wells will be installed at two of the four proposed stormwater systems following the approved infiltration well design/details and well specifications. 4) Confirm the soils encountered in the boring are similar to those previously logged by Aspect. If suitable, Aspect will approve the location and an infiltration test well will be installed. Aspect may modify the preliminary well design/details based on the boring data for use in infiltration well installation. 5) Install groundwater monitoring instrumentation. The infiltration test well borings will be advanced to at least ten feet below groundwater or into the contact with the underlying glacial till unit (approximately 30- to 50-feet below existing ground surface [bgs]). Aspect will make a manual measurement of the groundwater level at the time of drilling and will install a vibrating-wire piezometer to provide ongoing measurements of groundwater elevations. The instrumented boreholes will be grouted to approximately 25 feet bgs. Infiltration wells will be completed with six-inch, schedule 40 PVC wells casing, a 0.020- slot, ten-foot length steel V-wrap wire screen, and 6 x 9 Colorado Silica sand filter pack.

Aspect’s field geologist will coordinate with the infiltration test well design team as needed during the drilling and installation process. 7) Collect soil samples for laboratory tests. b) Borehole Infiltration Test (BIT) will be conducted in each well to estimate the saturated hydraulic conductivity of the receptor soil. The well testing will include the following task: 8) Based on the final test well installation details, Aspect will update the testing plan as needed. The 2017 City of Renton and the 2016 King County Surface Water Design Manuals do not provide guidance on BIT methods. Therefore, the BITs will be conducted in general accordance with the guidance and requirements in the 2016 City of Seattle Stormwater Manual. 9) Secure, test, and calibrate infiltration testing equipment as needed. 10) Coordinate with team members and site owner as needed to secure a water source, set up test equipment, and prepare for testing. 11) Aspect will conduct two (2) two-phase infiltration tests generally following the USBR Well Permeameter Method; consisting of a constant head test (Phase I) and falling head test (Phase II). a. Perform the test by adding water (obtained from a potable water source) to the test well to maintain a constant hydraulic head in the well. b. Monitor the flow rate with a flow meter or other method that is capable of measuring flow to within 5% of the total flow rate. c. Monitor water levels in the test well with a pressure transducer and datalogger on a maximum of five-minute intervals. d. Add water until the water level and rate of water added is constant (5% variation), or for a minimum of four hours. e. Once a constant rate is achieved, the Phase I test is complete. Begin the falling head portion of the test. Monitor water levels until the water level has fallen to less than 5% of the total head targeted during the constant rate portion of the test. f. In addition to the required wells, monitor groundwater elevations in nearby monitoring wells as available. c) Following testing, Aspect will tear down and clean-up equipment. It is assumed that the infiltration test wells will remain in place until a decision is made regarding: (a) the need for any retesting, (b) the need for any mounding analysis, (c) the potential to retain/enlarge the infiltration wells, and (d) the need to decommission the wells in accordance with State laws. 4.3. 30% Laboratory Testing and Analysis 1. Independent Laboratory Testing Soil samples retrieved from the soil borings and test pits will be returned to our laboratory for further examination and visual/manual classification. Soil samples will be tested by independent laboratories for grain size distribution with hydrometer and percent organic content and chemical analyses for cation exchange capacity and pH.

Estimate Long-term Design Infiltration Rates Aspect will complete data reduction for the BITs to evaluate the preliminary long term design infiltration rate(s) for the site, with appropriate correction factors. At the completion of this task, we will relay our results to the Otak team relative to the City’s interest to use a design infiltration rate greater than 20 inches per hour. 3. Mounding Analysis Mounding analyses are required for a facility that receives more than one acre of surface water and has less than fifteen feet depth to seasonal high groundwater (as measured from the bottom of the infiltration basin or trench) or other low permeability stratum. Monitoring of groundwater over the wet season will be completed to evaluate the vertical separation from the bottom of the facility to seasonal high groundwater needed for groundwater mounding. 4.4. Reporting (Draft at 30%) Based on Aspect’s characterization of the subsurface conditions and infiltration tests, Aspect will analyze the data and summarize our findings in a report. The report will include the following: a) Exploration and well logs and a site plan showing approximate exploration locations. b) Discussion of the soils encountered and details of well installations. c) Laboratory test results. d) Groundwater monitoring results and considerations. e) BIT results and estimated bulk saturated hydraulic conductivity of the receptor soil. f) Preliminary Groundwater mounding results. g) Recommendations for the long-term design infiltration rate(s) and PIT program for 60%. 4.5. Environmental Due Diligence Services Aspect will conduct due diligence for the approximately 14-acre Upper Balch Pit Property (Property; King County Tax Parcel 162305-9059) to evaluate, identify, and investigate environmental conditions that may impact the future stormwater system construction work. The work of this task focuses on a combined Phase I Environmental Site Assessment (ESA) and a limited subsurface investigation, as warranted. 1. Phase I Environmental Site Assessment Aspect will conduct a Phase I ESA in accordance with the guidelines prescribed in the ASTM International (ASTM) standard E1527-13 and prepare a formal report for Otak. The Phase I ESA will include the following: a) Conduct a site reconnaissance to observe and document current site conditions on the Property and activities at immediately adjacent properties. b) Interview the current owner(s), operators, and/or other persons known to have knowledge of the history of the Property, based on contact information provided by the client. c) Review environmental records for properties within the vicinity of the Property by obtaining and reviewing a regulatory records report. This report summarizes data available for the Property and properties located within distances of up to one mile from the Property with listings on local, state, and federal regulatory databases. d) Obtain and review reasonably ascertainable environmental records through a search of the Washington State Department of Ecology Toxics Cleanup Program Web Reporting Portal, which summarizes data and provides access to publicly available environmental documents for sites on Scope of Services (continued) K:\Project\33200\33201A\Contract\Supplement 2 - Monroe Ave NE Storm System Improvements - Phase 2 (Design and CM)\Amendment 2\20_1113\33201 Monroe Ave NE SOW 11.13.2020.docx City of Renton 11 Monroe Avenue NE Storm System Improvements Otak the CSCSL, HSL, No Further Action (NFA) Sites List, UST list, and LUST list. If deemed necessary based on information obtained from the Portal, review of environmental documents, reports, and records that can only be obtained through a formal request and review of hardcopy files at regional offices of the Washington State Department of Ecology. e) Review historical records, including archived tax assessor records at the Washington State Archives, historic aerial photographs, Sanborn Fire Insurance Maps, and Polk City Directories. f) Contact government agencies, including local fire and health departments, to inquire about and review information in their records pertaining to the Property, if available. g) Prepare a report summarizing the results of the data research, site reconnaissance observations, interviews, and file review. The report will identify on- and off-site recognized environmental conditions (RECs) for the Property. h) Provide recommendations regarding further evaluation of RECs identified for the Property, if warranted. 2. Limited Subsurface Investigation Based on the results of the Phase I ESA, Aspect will complete a separate proposal with a brief work plan for a limited subsurface investigation and the time and materials cost estimate to evaluate RECs identified in the Phase I ESA. The scope of services for the limited subsurface investigation, to be confirmed or modified early in the work of this task, will include the following, with exact locations and depths to be determined based on the Phase I ESA results: a) During subsurface work described in Task 4.2, collect soil and grab groundwater samples from boring and/or monitoring well locations. b) Submit soil and groundwater samples for laboratory analysis. c) Prepare a Limited Subsurface Investigation Report to document the results of the investigation. d) Disposal of investigation-derived waste generated during the subsurface investigation as non-hazardous waste. Assumptions for Task 4: 1. Aspect assumes the BIT during 30% design effort will be getting initial infiltration results to aid in the decision for 60% design when additional and more reliable PIT will be performed to help with the final design of the underground infiltration system. 2. Aspect’s scope and fee does not include obtaining and reviewing the title report/chain of title for the Property, unless provided by Otak or Renton. If needed, Aspect can provide these services, under a supplemental agreement that would draw upon the design contingency budget. 3. Aspect’s scope and fee does not include evaluation of potentially hazardous building materials (e.g., asbestos, lead-based paint, or mold). If needed, Aspect can provide these services, under a supplemental agreement that would draw upon the design contingency budget. 4. Aspect’s Geotechnical and Hydrogeological Services, Task 4, scope and cost estimate is preliminary and assumes a combined drilling effort with the work described in Task 4.5, collection of soil and grab groundwater samples and laboratory analysis of up to 18 samples for total petroleum hydrocarbons (TPH) and carcinogenic polycyclic aromatic hydrocarbons (cPAHs), which are commonly found in fill soil, and disposal of up to four drums of non-hazardous investigation-derived waste.

Each boring location is suitable for installation of a test well. Additional borings due to encountering unsuitable conditions will require additional funds. 6. The City or Segale will provide access to water for drilling and testing. 7. The scope covers one infiltration test per well or pit. 8. Two soil samples per explorations will be submitted for grain size analysis (sieve and/or hydrometer) and two samples submitted for chemical analyses (CEC and %OM, or equivalent). 9. No review cycle on the Deep Infiltration Testing Report. 10. The scope does not include infiltration well decommissioning services. 11. Aspect will prepare permit applications on behalf of the City of Renton if required. Renton will submit the permit applications and pay associated fees as well as applications for right-of-entry to private property that may be necessary to complete the explorations. 12. Aspect will contact the Washington Utilities Coordinating Council One Call service to locate utilities at the proposed exploration locations. Aspect will also request the assistance of Otak and Renton to help identify any underground utilities to be avoided. 13. Aspect will hire an experienced drilling contractor to supply and operate the drilling equipment to complete the borings and an experienced earthwork contractor to supply and operate the track-hoe (or backhoe) to complete the test pit explorations. 14. The explorations will be observed by a geotechnical engineer or geologist from Aspect who will classify the soils encountered, obtain representative samples of the various soils, and develop detailed logs of each exploration. The samples will be sealed and transported to the Aspect laboratory for reexamination and testing. The explorations will be located in the field by pacing or tape measurement from existing site features. Using these techniques, the locations of the explorations will be established for presentation on a site plan which will be provided by the project team. 15. The borings will be backfilled pursuant to the procedures of Washington Department of Ecology (in place at time of project). 16. Otak will survey and map the location of the six borehole infiltration tests/wells where the thickness of fill makes a PIT infeasible (subtask 4.2.1). using survey grade equipment. 17. The boring explorations area may be backfilled with the soil derived from the area, and the backfill tamped in place with the backhoe bucket and smoothed. The backfill cannot be compacted to a density consistent with structural fill using the backhoe; therefore, the backfill may need to be removed and recompacted during site development, depending on location. The work areas will not be revegetated and evidence of the ground disturbance may remain following the work. 18. Renton will coordinate with and obtain right of entry and easement(s) from the property owner to provide access for design, construction, and maintenance of the facility. 19. A site map has been provided to Aspect by Renton and Otak. Aspect will review future design drawings of the selected facility alternative, the proposed private development of the Segale site and any street or utility project(s) proposed in the vicinity of the project site provided by Otak as the design progresses to 30% design. 20. The City will provide Otak and Aspect with one set of written review comments marked on one set of submitted documents at the 30% design level Scope of Services (continued) K:\Project\33200\33201A\Contract\Supplement 2 - Monroe Ave NE Storm System Improvements - Phase 2 (Design and CM)\Amendment 2\20_1113\33201 Monroe Ave NE SOW 11.13.2020.docx City of Renton 13 Monroe Avenue NE Storm System Improvements Otak Deliverables for Task 4: 1.

Preliminary (30%) Design 5.1. Update Hydrologic and Hydraulic Analyses Otak will update the WWHM-SWMM hydrologic and hydraulic model, previously developed in Phase I Task 5.2 in of the project (Alternatives Analysis phase), that was developed to technical analyses levels 1 to 3, This task includes updating to a Level 4, as defined in Table 2, to size the infiltration facility, pre-treatment facility, and the conveyance system including hydraulic controls for final design of the facilities. Expected changes to the previous model(s) include: 1. Updating the Hydrologic Input into the Mounding analysis for project infiltration The mounding analysis, in Task 4, for the project infiltration facility is an iterative process where the storm water runoff hydrology is routed into the proposed infiltration facility, the hydrologic output (infiltration) is input into the mounding analysis to assess potential mounding impacts, this could also change the design infiltration rate, if mounding encroaches on the bottom of the infiltration facility. In this task, Otak will update the hydrologic and hydraulic inputs from the site improvements at the Segale property. 2. Update model with the final hydraulic controls to and from the storm water management facilities In this task, Otak will finalize the H/H model hydraulic controls to split flows to the infiltration facility, and to design a high flow bypass and drain the facilities for maintenance. 5.2. Technical Information Report Otak shall prepare a Draft Technical Information Report (TIR) for this regional stormwater facilities project, based on appropriate requirements set forth in the current Renton adopted and amended KCSWDM. The TIR will include in the appendices, summaries and supporting information of the Stakeholder and Public Engagement (Task 2), the technical investigations and analysis (Task 4 and 5), as well as, the 30% Plans in the Draft TIR.

Utility Coordination Utility Adjustments/Relocation Evaluation Otak will identify anticipated adjustments and/or relocation of utilities within the existing streets that will be used for site access and/or necessary drainage system modifications. Based on the existing utility records and/or utility-field locates, if available, identified conflicts with proposed street drainage improvements will be evaluated to determine if the drainage design can be modified to avoid any of the anticipated conflicts. 1. Obtain/compile existing utility data, for preliminary design Otak will initially coordinate and obtain records from utility companies to verify locations of existing facilities, on Monroe Avenue and on the Segale Property, and confirm agency requirements. Otak will review and compile the record documentation drawings and verify the utility horizontal locations surveyed and shown on the design base maps. Otak will retain a utility locate service to mark underground utilities for use in field surveying and basemapping utility locations. Otak will coordinate with Renton to field mark existing City utilities. Otak will assess existing water, sanitary sewer, power, and storm drainage pipes relative to proposed improvements and prepare preliminary plan identifying required relocations limits, adjustment locations, and where possible, present options for minimizing utility relocations/adjustments. This assessment will include providing a preliminary estimate of cost to underground existing overhead utilities, if needed and/or desired by the City.

Quantities will be organized into standard bid items (supplemented by additional non-standard items, if necessary) conforming to the project bid schedule. The construction cost estimate will include appropriate contingencies to reflect the level of design complete. 5.6. 30% Design Review Otak will coordinate and facilitate with the City for one (1) two-hour meeting to review the Draft 30% Design Plans, Cost Estimate, and TIR. At the meeting, the City will provide Otak with comments to the Draft 30% Design Plans, Cost Estimate, and TIR. The meeting shall include, but not be limited to, discussing and reviewing the suggested revisions to these documents. Otak will assemble and submit interim progress submittal documents for review and comment. The City shall review and provide Otak a consolidated set of written review comments from all reviewers on a returned electronic form provided by the Otak. Otak will subsequently evaluate the comments and provide the City with written responses to each comment for clarification and concurrence. 5.7. Perform Quality Assurance and Quality Control Otak will implement Quality Assurance and Quality Control to provide ongoing review on all hydrologic and hydraulic modeling throughout the design of the stormwater facilities. Otak will provide quality assurance on all deliverable products to support this task, including work performed by sub-consultants, and submit quality control check-list for all analyses and documents produced in this Task 5. The Quality Review Checklist will be signed off by PM, Task Leads and an independent reviewer. Assumptions for Task 5: 1. The hydrologic models will include two scenarios, one without climate change and current landuses, and one with climate change and future landuses based on the built-out zoning data. 2. The regulatory landuse conditions (Forested) will not be modeled, as the infiltration facility is assumed to be able to infiltrate all flows required to meet flow control standards. 3. No structural retaining walls or footings are included in this scope and fee; adequate space will be available to grade construction slopes to a stable grade. 4. The Draft TIR submittal will be submitted with the Draft 30% Design Plans and Cost Estimate, developed in Task 5.2, and will include as a separate attachment, the signed QC checklist. 5. The Final TIR will be submitted with the 60% Design Plans, Specifications, and Cost Estimate.

The Preliminary design will be based on the design concepts and layout of the Selected Alternative, selected in Phase I of the project. 12. Renton will consolidate duplicate comments, and approve or remove comments from all. 13. Minor changes to the concepts are expected during the Preliminary Design review to accommodate permit requirements and review comments, and the City approved changes will be incorporated into the 60% Design. 14. Major changes to the design concept could be the result of significant changes in site conditions such as 1) the Segale Property is found to have wetlands or contaminated soils that would be impacted during construction, 2) Segale Properties does not provide a Letter of Agreement and a Maintenance Easement for this project, 3) The hydrogeologic investigations uncovers subsurface conditions that significantly impacts the design infiltration rate and/or ground water mounding impacts. 15. Major design conceptual changes from the Selected Alternative, from Phase I, is not included in this scope and fee estimate. If major changes are required to the concepts or layout of the Preliminary Design, then Otak will assess the impact of the City required or desired changes, develop and submit contract supplement, with the scope and fee estimate needed to revise the design submit, and a request to Renton for approval to use the Design Continency to revise the Preliminary Design per the attached supplement. Otak will not proceed to Final Design before Renton approves the supplement or provide clarifying direction on how to proceed with the design. Deliverables for Task 5: 1. Draft TIR, three paper copies (upon request); one in MS Word; and one PDF copy. 2. Electronic copies of all hydrologic and hydraulic models will be included in an appendix of the Draft TIR report with a summary of the model input and output and model analysis. 3. 30% Design Plans, as listed in Table 3, will be prepared in AutoCADD, and submitted as three paper full- size (upon request), and one PDF half-sized. 4. 30% Cost Estimate submittal includes three paper copies (upon request), and one MS Excel file copy. 6. ENVIRONMENTAL SERVICES AND PERMIT SUPPORT Otak will lead the project environmental documentation and permitting process, including developing the permitting strategy, identifying required environmental documentation, coordinating with regulatory agencies if necessary, and preparing environmental studies and the final permit applications. A review of historical aerial photography and land use records indicates the Upper Balch Pit was a permitted sand/gravel pit from 1962 to 1982, and has been reclaimed since 1982 and repurposed for stormwater management. Previous studies have indicated no wetlands on site, but that surface ponding may occur during wet months. However, the National Wetland Inventory maps a wetland in the center of the pit. To support the land use applications necessary for construction, Otak shall: 6.1. Conduct Site Investigation and Prepare Critical Areas Memorandum Two (2) Otak biologists shall conduct one (1) two-hour site visit plus travel to document existing conditions and the absence of regulated critical areas on site. Baseline environmental data will be collected to prepare a Technical Memorandum documenting the results.

Wetland and watercourse identification will follow federal and state manuals for consistency with City of Renton Municipal Code. Critical areas are not anticipated to occur on site, but documentation of their absence will be necessary for land use submittals and for compliance with SEPA. 6.2. Prepare Draft SEPA Checklist Otak will prepare the SEPA Checklist required to accompany land use permit submittals. Otak will prepare a draft SEPA checklist for review by the City. Assumptions for Task 6: 1. Any aquatic resources (e.g., wetlands, ponds, watercourses) identified within the Upper Balch Pit site will be considered artificial in nature and created incidental to construction and/or site operations, and therefore not regulated by the USACE, Washington Department of Ecology, or the City of Renton per the city’s critical areas ordinance. 2. Critical areas covered under this scope include wetlands, Fish and Wildlife Habitat Conservation Areas (FWHCAs), watercourses, well-head protection areas, and flood hazard areas. Steep slopes will be addressed under the geotechnical scope of services. 3.
