The project vicinity is located along N 30th St, between Burnett Ave N and Park Ave, and along Burnett Ave N between N 30th St and N 32nd St, within the Residential-8 (R-8) zoning designation. The project would increase drainage system capacity and reduce flooding at the local sag point on N 30th St, near 1104 N 30th St, by conveying runoff that would otherwise drain to an undersized and difficult to maintain drainage system that extends through private properties. Surrounding properties in the project vicinity are single-family residences. The new 12 to 1S-inch diameter pipe would be approximately 1,400 linear feet within the public rights-of-way and would connect with the existing storm system at the intersection of N 32nd St and Burnett Ave N. Discharge from the drainage area would continue to be to Lake Washington. The new conveyance system would be in the public right-of-way in a trench approximately 5 feet wide and approaching 10 feet in depth. The construction trench corridor would be approximately 12 feet in width. Approximately 1,400 cubic yards of soil is proposed for excavation and export. Backfill would be brought to the site. The slope of the pipe ranges from 1 to 12 percent. There is a small area of sensitive slopes in the street right-of-way (at the addresses 1003 and 1007 N 30th St). No trees would be impacted. A Geotechnical Report, Environmental Checklist, and preliminary plan and profile were provided. During construction, the street parking area would be used for storing construction equipment and materials. Access to local driveways would be maintained, except when construction needs to cross or block a driveway. All disturbed areas of streets and sidewalks would be restored to existing improvements and parking. Construction would occur approximately March 2016 through July 2016, primarily Monday through Friday with work hours between 7:00 AM and 5:00 PM and truck hauling limited to 8:30 AM to 3:00 PM, with weekend work only as approved by the City.

Ken ton DETERMINATION OF NON-SIGNIFICANCE-MITIGATED (DNSM) MITIGATION MEASURES AND ADVISORY NOTES PROJECT NUMBER: APPLICANT: PROJECT NAME: LUAls-000G07, ECF City of Renton; Attn: Joseph Farah; 10555 Grady Way, 5th FL; Renton, WA 98057 N 30th St & Burnett Ave N Storm System Improvements PROJECT DESCRIPTION: The applicant, the City of Renton, is requesting Environmental (SEPA) Review to extend stormwater pipe and catch basins in the Kennydale neighborhood. The project vicinity is located along N 30th St, between Burnett Ave N and Park Ave, and along Burnett Ave N between N 30th St and N 32nd St, within the Residential-8 (R-8) zoning designation. The project would increase drainage system capacity and reduce flooding at the local sag point on N 30th St, near 1104 N 30th St, by conveying runoff that would otherwise drain to an undersized and difficult to maintain drainage system that extends through private properties. Surrounding properties in the project vicinity are single-family residences. The new 12 to 18-inch diameter pipe would be approximately 1,400 linear feet within the public rights-of-way and would connect with the existing storm system at the intersection of N 32nd St and Burnett Ave N. Discharge from the drainage area would continue to be to Lake Washington. The new conveyance system would be in the public right-of-way in a trench approximately 5 feet wide and approaching 10 feet in depth. The construction trench corridor would be approximately 12 feet in width. Approximately 1,400 cubic yards of soil is proposed for excavation and export. Backfill would be brought to the site. The slope of the pipe ranges from 1 to 12 percent. There is a small area of sensitive slopes in the street right-of-way (at the addresses 1003 and 1007 N 30th St). No trees would be impacted. A Geotechnical Report, Environmental Checklist, and preliminary plan and profile were provided. During construction, the street parking area would be used for storing construction equipment and materials. Access to local driveways would be maintained, except when construction needs to cross or block a driveway. All disturbed areas of streets and sidewalks would be restored to existing improvements and parking. Construction would occur approximately March 2016 through July 2016, primarily Monday through Friday with work hours between 7:00 AM and 5:00 PM and truck hauling limited to 8:30 AM to 3:00 PM, with weekend work only as approved by the City.

Utilities: The existing stormwater system in N 30th St currently conveys water through private property to the north, in the middle of the block, to connect to N 31" St. This system does not have sufficient capacity and localized flooding occurs. The project would take the existing storm lines in N 30 th St and extend them to the intersection of N 30th St and Burnett Ave N, and extend the new line north on Burnett to N 32" St and Burnett Ave N, to connect with the system that discharges into Lake Washington. The storm lines within the private properties would not change and continue to convey to the existing system to the north. A 96-inch concrete sewer line is located in Burnett Ave N. 2. Streets: The project site is the public right-of-way where there are improved streets. The subject section of storm system is located along N 30th St between Burnett Ave N and Park Ave N and along Burnett Ave N between N 30 th St and N 32" St. Project construction will occur within approximately 16,800 sf of public right-of-way (approximately 12 feet wide trench with an approximate 1,400-foot length). 3. Fire Protection: City of Renton Fire Department. I PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240. the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period. B. Mitigation Measures 1. The applicant shall follow the recommendations included in the Geotechnical Engineering Report, prepared by Associated Earth Sciences, Inc, dated May 14, 2014. 2. The applicant shall provide a fill source statement for fill used at the site for project development within the N 30 th St right-of-way within the Aquifer Protection Area. The fill source statement shall be submitted with the construction permit application. C. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: ERe Report 15-000607 City oj Renton Department of Community & Economic Development N 30TH ST & BURNETT AVE N STORM SYSTEM IMPROVEMENTS Report of September 21,2015 L Earth Environmental Review Committee Report LUA15-000607, EeF Page 5 of 7 Impacts: A Geotechnical Engineering Report, prepared by Associated Earth Sciences, dated May 14, 2014 (Exhibit 7) and a SEPA Environmental Checklist prepared by the applicant (Exhibit 6) have been provided with the application. Both provide analysis of existing conditions, proposed earthwork, and impacts. The surface elevation along Burnett Ave N rises gradually north to south from elevation 102 feet to elevation 120 feet between N 30th 5t and N 32"' St (Exhibit 7, page 2). Existing grade along N 30th 5t rises to the east from elevation 120 feet to elevation 170 feet along the alignment. According to City of Renton mapping software, a portion of the project area is within Moderate Landslide area (Exhibit 9) and there are Sensitive slopes of approximately 25-40% near the address 1003 N 30 th St (Exhibit 8) on the south side of the public right-of-way. Construction will primarily be in asphalt covered streets in the public right-of-way (Exhibit 11). Along N 30 th St, the proposed pipe is generally located along the gutter, and construction will largely take place in the sidewalk on the north side of the street. The installation of the proposed storm system is expected to require open excavations approaching depths of 10 feet (Exhibit 7, page 6). The geotechnical investigation as discussed in the submitted Geotechnical Report, includes three drilled exploration borings along the storm system alignment. Borings were conducted in mid-April when ground water levels in unconfined aquifers in the Puget Lowland are typically at or near their seasonal high (Exhibit 7, pages 2 and 5). The 'Subsurface Conditions' section ofthe Geotechnical Report states that the explorations in the right-of-way encountered fill soils composed of very loose, granular sediments underlain by natural sediments consisting of medium dense to very dense sand, although the subsurface conditions actually encountered during constructionwithin the roadway could encounter compacted trench backfill associated with several existing underground utilities (Exhibit 7, page 4). The three borings encountered four sediment types (Fill, Vashon Recessional Outwash, Vashon Lodgement Till, and Vashon Advance Outwash). Ground water seepage was encountered in two borings on N 30th St at a depth of approximately 5 feet in both borings and at approximately 15 feet below existing grade in the most easterly boring (Exhibit 7, Figure 3). The Geotechnical Report states that the planned storm system replacement is feasible provided that the recommendations in the report are adhered to ("Design Recommendations -Introduction", page 6). The Geotechncial Report makes construction design recommendations for trenching, drainage, and erosion hazards. The Geotechnical Report states that the erosion potential of the site is considered to be low although erosion may increase temporarily during construction. To mitigate erosion hazard potential, five additional minimum erosion control recommendations should be added to the project temporary erosion and sedimentation control plan (Exhibit 7, page 8). The five additional recommendations leaving pavement areas in place and vacuum sweeping, adding filter socks to catch basins in the vicinity, stockpiling soils, and revegetating or paving disturbed areas. Based on the recommendations included in the provided Geotechnical Engineering Report, staff recommends as a mitigation measure that the subject project comply with the recommendations. Mitigation Measures: The applicant shall follow recommendations in the Geotechnical Engineering Report. Nexus: SEPA Environmental Regulations, RMC 4-3-050 Critical Areas. Z, Water a. Aquifer Protection Area Impacts: The trench work in N 30th St may occur within the City of Renton Aquifer Protection Area Zone 2 (Exhibit 10). Construction work in N 30th St right-of-way is proposed on the northern side of the street. The Aquifer Protection Area is located on the southerly side of the street. The overall purpose of the aquifer protection regulations is to protect aqUifers used as potable water supply sources by the City from contamination by hazardous materials. Some uses are restricted that store, handle, treat, use, or produce ERe Report 15-000607 City of Renton Department of Community & Econom;c Development N 30TH ST & BURNETT AVE N STORM SYSTEM IMPROVEMENTS Report 01 September 21, 2015 Environmental Review Committee Report LUA15-000607, ECF Page6017 substances that pose a hazard to groundwater quality. Since fill is proposed for project development, a fill source statement would be required to be submitted to the City to ensure clean fill is used. Impacts to the Aquifer Protection Area are not anticipated as a result of the subject project. Mitigation Measures: The applicant shall provide a fill source statement, for fill used at the site for project development within the N 30th St right-of-way within the Aquifer Protection Area. The fill source statement shall be submitted with the construction permit application Nexus: SEPA Environmental Regulations, RMC 4-3-080 Critical Areas, RMC 4-6-030 Drainage Surface Water Standards. b. Storm Water Impacts: The projects proposal would add a new storm water system along N 30 th St and Burnett Ave N in the public right-of-way. The Environmental Checklist states that the project would not change the amount of storm water collected or the discharge location. The proposed project re-routes runoff from one piped drainage system to another and as such does not affect the drainage pattern within or in the vicinity of the project (Exhibit 6). The project would increase the capacity of the storm water drainage system and reduce the potential for flooding. Approximately 1,400 linear feet of new storm pipes would be added. The Environmental Checklist describes the existing method of collection, conveyance, and disposal for storm water in the area (Exhibit 6, page 3). Storm water runoff to the project area is generated from the residential and commercial areas east of the project area. Storm water runoff is collected by catch basins in the streets and is conveyed to the west, along N 30 th St, by the existing 12-inch storm water pipes. The drainage area at the connection point to the existing system at the intersection of N 32 0d St and Burnett Ave N is approximately 40 acres. The estimated peak flows at the downstream end ofthe project area at the intersection of N 32 0d and Burnett Ave N ranges is approximately 20 cubic feet per second for the 25-year, 24-hour storm event. From the N 32 0d St/Burnett Ave N intersection, storm water runoff is conveyed by a pipe that extends north along Burnett Ave Nand then west. This storm crosses under Lake Washington Blvd and discharges to Lake Washington. That Environmental Checklist states: • The use of typical erosion control measures per the 2009 KCSWDM would be used during construction to prevent soil and sediment from entering the storm water system (Exhibit 6, page 8). • The Environmental Checklist states that during construction, if fuel and oil spills occur, they would be mitigated (Exhibit 6, page 11). Staff recommends that the City consider requiring a Spill Prevention, Control, and Countermeasures (SPCC) Plan for the contractor that will perform proposed work. Staff has already recommended that the recommendations ofthe Geotechnical Report (Exhibit 7) be followed as a mitigation measure. Mitigation Measures: No further mitigation required. Nexus: None. 3_ Transportation Impacts: It is anticipated that temporary impacts to traffiC would result from the proposed project during construction. The project would result in the closure of areas along N 30th St and Burnett Ave N during construction. Construction would occur approximately March 2016 through July 2016, primarily Monday through Friday, with work hours between 7:00 AM and 5:00 PM and truck hauling limited to 8:30 AM to 3:00 PM, with weekend work only as approved by the City (Exhibit 13). A traffic control plan would be required during construction to ensure emergency access to all homes located on the street is maintained throughout construction (Exhibit 6 subsection 14 "Transportation"). The submitted Environmental Checklist states that a traffic control plan will be prepared by the contractor for approval by the City, that will restrict parking and may limit access to construction areas and that the ERe Report 15-000607 City of Renton Department of Community & Economic Development N 30TH ST & BURNETT AVE N STORM SYSTEM IMPROVEMENTS Report of September 21, 2015 Environmental Review Committee Report LUA15-000601, ECF Page 7 of 7 contractor would use the parking strip to store construction material and equipment. The checklist further states that access to local driveways will be maintained, except when construction needs to cross or block a driveway. Areas including on-street vehicle parking, asphalted areas, and sidewalks that are impacted would be restored in kind as part of the project. Mitigation Measures: No further mitigation required. Nexus: Not applicable. D. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers.

This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. INSTRUCTIONS FOR APPLICANTS: ~ This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use "not applicable" or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision-making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. INSTRUCTIONS FOR LEAD AGENCIES: Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the leadil~l;xi.s_~~s9P-n,sible for the completeness and accuracy of the checklist and other supporting ddaLimer1fsl. \! r~ j) Entire Document H:\File Sys\SWP-Surface Available Upon Request 30th EC.docx ,1l,UG 1 0 2015 P)\27-3716:'N'~O;;~t'~urn:~\i~~4~EPA\4 N , , " . . . ~', _, i.'

This system would reduce flooding at the local sag point on N 30 th St near 1104 N 30 th St by conveying runoff that would otherwise drain to an undersized and hard to maintain drainage system that extends north through private properties. The purpose of the project is to alleviate the flooding has occurred at the sag point and on adjacent properties during significant storm events the last 10 years. Approximately 180 linear feet of existing storm pipes will be replaced and 1150 linear feet of new storm pipes will be added. The exact pipe sizes and locations will be determined in the final design. New catch basins will be placed at various locations along N 30th St and Burnett Ave N. Construction will primarily be in asphalt covered streets in the City right-of-way. Along N 30 th St, the proposed pipe is generally located along the gutter and as such construction will largely take place in the sidewalk on the north side. The new storm system will be placed in a trench approximately 5 feet wide and 4-to 9-feet deep. Approximately 1,500 cubic yards of soil may be excavated to install the new storm system. Backfill soil will be hauled in from licensed gravel pits. All disturbed asphalt areas will be patched with new asphalt. The disturbed sidewalk on N 30th St will be restored in kind .. The estimate construction cost is approximately $550,000. Construction will start at the intersection of N 32 nd St and Burnett Ave N and will proceed south to the intersection of N 30th St and Burnett Ave N, and then east till the local sag point on N 30 th St near 1104 N 30th St. During construction, parking on each block will be restricted, and the block will be limited to local access only. The contactor will use the parking strip or shoulder to store construction material and equipment. Access to local driveways will be maintained, except when construction needs to cross or block a driveway. After construction is completed all streets will be restored to existing access and parking. The project will consist of trenching in asphalt covered streets (and along sidewalk gutter for half of the project) so erosion is not likely to occur. Typical erosion control measures such as storm grate inlet protection and covering any exposed soil stockpiles, as specified in the King County Surface Water Design Manual, will be used. The soils in the area are classified by the National Resources Conservation Service as InC (Indianola Loamy Fine) in the King County, Washington Soil Survey. The typical profile of this soil is loamy fine sand, and sand at larger depths. There is no land use permit required for this project. The zoning designation is City right-of-way but the adjacent area is zoned single family residential. There are no wetlands, water bodies, steep slopes or other hazard areas within the project extents. There are also no trees to be removed or impacted (and as such no landscape plan is needed). The existing topography consists of rolling to flat slopes. Exiting contours lines are shown on the site plan.

This system would reduce flooding at the local sag point on N 30 th St near 1104 N 30 th St by conveying runoff that would otherwise drain to an undersized and hard to maintain drainage system that extends north through private properties. The purpose of the project is to alleviate the flooding has occurred at the sag pOint and on adjacent properties during significant storm events the last 10 years. Approximately 180 linear feet of existing storm pipes will be replaced and 1150 linear feet of new storm pipes will be added. The exact pipe sizes and locations will be determined in the final design. New catch basins will be placed at various locations along N 30th St and Burnett Ave N. Construction will primarily be in asphalt covered streets in the City right-of-way. Along N 30th St, the proposed pipe is generally located along the gutter and as such construction will largely take place in the sidewalk on the north side. The new storm system will be placed in a trench approximately 5 feet wide and 4-to 9-feet deep. Approximately 1,500 cubic yards of soil may be excavated to install the new storm system. Backfill soil will be hauled in from licensed gravel pits. All disturbed asphalt areas will be patched with new asphalt. The disturbed sidewalk on N 30 th St will be restored in kind .. The estimate construction cost is approximately $550,000. Construction will start at the intersection of N 32 nd St and Burnett Ave N and will proceed south to the intersection of N 30th St and Burnett Ave N, and then east till the local sag point on N 30 th St near 1104 N 30 th St. During construction, parking on each block will be restricted, and the block will be limited to local access only. The contactor will use the parking strip or shoulder to store construction material and equipment. Access to local driveways will be maintained, except when construction needs to cross or block a driveway. After construction is completed all streets will be restored to existing access and parking. The project will consist of trenching in asphalt covered streets (and along sidewalk gutter for half of the project) so erosion is not likely to occur. Typical erosion control measures such as storm grate inlet protection and covering any exposed soil stockpiles, as specified in the King County Surface Water Design Manual, will be used. The soils in the area are classified by the National Resources Conservation Service as InC (Indianola Loamy Fine) in the King County, Washington Soil Survey. The typical profile of this soil is loamy fine sand, and sand at larger depths. There is no land use permit required for this project. The zoning designation is City right-of-way but the adjacent area is zoned single family residential. There are no wetlands, water bodies, steep slopes or other hazard areas within the project extents. There are also no trees to be removed or impacted (and as such no landscape plan is needed). The existing topography consists of rolling to flat slopes. Exiting contours lines are shown on the site plan. AUG 1028'S CONSTRUCTION MITIGATION DESCRIPTION N 30th St I Burnett AVE N STORM SYSTEM IMPROVEMENT PROJEC Proposed Construction Dates: Approximately March 2016 through July 2016. Hours of Operation: Monday through Friday between 7:00 AM and 5:00 PM Proposed Hauling/Transportation Routes: The project area is served by N 30 th St, N 31 st St, N 32 nd St, Park Ave N and Burnett Ave N. The contract will most likely use N 30 th 5t and Burnett Ave N for access to construction area. The contractor may access the project area from 1·405 or Lake Washington Blvd N. Truck hauling on arterial streets will be limited to the hours of 8:30 AM to 3:00 PM, Monday through Friday. Work on weekends will only occur with approval from the City. The contractor will be required to file a Traffic Control Plan with the City to identify hauling routes and traffic control measures for the construction area. Erosion control measures such as storm drain inlet protection per the King County Surface Water Manual will be used. Any soil stockpiles not in use will be covered with plastic sheets during rainy periods. Stockpiles and the working area may be watered to reduce dust generation, if needed. All construction equipment will be required to have muffler and exhaust systems in good working order.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) I!:!gjill This project consists of adding a new storm system along N 30 th St and Burnett Ave N in the City right-of-way. This system would reduce flooding at the local sag point on N 30 th St near 1104 N 30 th St by conveying runoff that would otherwise drain to an undersized and hard to maintain drainage system that extends north through private properties. Local flooding has occurred at the sag point and adjacent properties numerous times during the last 10 years. Approximately 180 linear feet of existing storm pipes will be replaced and 1150 linear feet of new storm pipes will be added. The exact pipe sizes and locations will be determined in the final design. New catch basins will be placed at various locations along N 30 th 5t and Burnett Ave N. Construction will primarily be in asphalt covered streets in the City right-of-way. Along N 30 th St, the proposed pipe is generally located along the gutter and as such construction will largely take place in the sidewalk on the north side. The new storm system will be placed in a trench approximately 5 feet wide and 4-to 9-feet deep. Approximately 1,500 cubic yards of soil may be excavated to install the new storm system. Backfill soil will be hauled in from licensed gravel pits. All disturbed asphalt areas will be patched with new asphalt. The disturbed sidewalk on N 30 th St will be restored in kind. H:\File Sys\SWP -Surface Water Projects\SWP·27 -Surface Water Projects (CIP)\27-3716 N 30th St-Burnett\1194 SEPA Construction will start at the intersection of N 32 nd St and Burnett Ave N and will proceed south to the intersection of N 30 th St and Burnett Ave N, and then east till the local sag point on N 30 th St near 1104 N 30 th St. A traffic control plan will be prepared by the contractor for approval by the City that will restrict parking and may limit access to construction areas. The contactor will use the parking strip or shoulder to store construction material and equipment. Access to local driveways will be maintained, except when construction needs to cross or block a driveway. After construction is completed all streets will be restored to existing access and parking. 12. location of the proposal.

Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. I!:!lllill Storm water runoff to the project is generated from the residential and commercial areas east the project area. Storm water runoff is collected by catch basins in the streets and is conveyed to the west, along N 30th St, by the existing 12-inch storm water pipes. The drainage area to the new storm pipe on N 30 th St is approximately 13.5 acres. Runoff from this area wi" be collected in the proposed storm system on N 30th St. The drainage area at the connection point to the existing system at the intersection of N 32nd St and Burnett Ave N is approximately 40 acres. The estimated peak flows at the downstream end of the project area at the intersection of N 32 nd St and Burnett Ave N ranges is approximately 20 CFS for the 2S-year, 24-hour storm event. From the N 32nd St/Burnett Ave N intersection, storm water runoff is conveyed by a pipe that extends north along Burnett Ave N and then west. This storm crosses under Lake Washington Blvd and discharges to Lake Washington. The project will not change the amount of storm water collected or the discharge location. 2) Could waste materials enter ground or surface waters? If so, generally describe. I!:!lllill The use of typical erosion control measures per the 2009 KCSWOM during construction will be used to prevent soil and sediment from entering the storm water system. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. The proposed project reroutes runoff from one piped drainage system to another and as such does not affect the drainage pattern within or in the vicinity of the project. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: There are no such proposed measures. The project will not change the amount of storm water collected. The project will increase the capacity of the storm water drainage system, and reduce the potential for flooding. H :\File Sys\swP .

PROJECT AND SITE CONDITIONS 1,0 INTRODUCTION This report presents the results of Associated Earth Sciences, Inc. 's (AESI's) subsurfaee exploration and geotechnical engineering report for the proposed N. 30 th Street / Burnett Avenue N. storm system replacement. The subject section of storm system is located along N. 30'h Street between Burnett Avenue N. and Park Avenue and along Burnett Avenue N. between N. 30 th Street and N. 32nd Street in Renton, Washington (Figure 1). The existing site features and approximate locations of the explorations accomplished for this study are presented on the "Exploration Plan and Profile," Figures 2 and 3. In the event that any changes in the nature, design, or location of the project are planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. I ,I Purpose and Scope The purpose of this report was to provide subsurface data to be utilized in the design and development of the aforementioned project. Our study included drilling three exploration borings along the storm system alignment, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments and ground water conditions. Geotechnical engineering studies were also conducted to provide recommendations for the proposed storm system replacement. This report summarizes our current fieldwork and presents descriptions of the subsurface conditions found along the storm system alignment and provides geotechnical recommendations based on our present understanding of the project. 1.2 Authorization Written authorization to proceed with this study was granted by Mr. Fred Williamson. Our study was accomplished in general accordance with our scope of work provided to PACE Engineers via email on March 17,2014. This report has been prepared for the exclusive use of PACE Engineers, the City of Renton, and their agents, for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner. No other warranty, express or implied, is made. May 14,2014 ASSOCIATED EARTH SCIENCES, INC. SSlld -KE140150A3 -PrDjectsI20140J50IKEIWP Page 1 N. 3(1" Street / Burnelt Avenue N. Storm System Renton, Washington 2.0 PROJECT AND SITE DESCRIPTION SubsU/jace Exploration and Geotechnical Engineering Report Project and Site Conditions The project consists of the installation of a new storm system located along N. 30th Street between Burnett Avenue N. and Park Avenue and along Burnett Avenue N. between N. 30th Street and N. 32,d Street in Renton, Washington (Figure I). The surface elevation along Burnett Avenue N. rises gradually north to south from elevation 102 feet to elevation 120 feet between N. 30th Street and N. 32"' Street. Existing grade along N. 30'" Street rises to the east from elevation 120 feet to elevation 170 feet along the alignment. The existing site features and approximate locations of the explorations accomplished for this study are presented on the "Exploration Plan and Profile," Figures 2 and 3. As shown on the "Exploration Plan and Profile" (Figures 2 and 3), a total of nine manholes are located along the subject length of storm system. 3.0 SUBSURFACE EXPLORATION Our field study included drilling three exploration borings along the storm system alignment to gain subsurface information about the site. The various types of sediments, as well as the depths where characteristics of the sediments changed, are indicated on the exploration logs presented in Appendix A. The depths indicated on the logs where conditions changed may represent gradational variations between sediment types. The approximate locations of the exploration borings are depicted on Figures 2 and 3. The conclusions and recommendations presented in this report are based, in part, on the conditions encountered in the exploration borings completed for this study. The number, locations, and depths of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions beyond the field explorations is necessary. Differing subsurface conditions may be present outside of the area of the field explorations due to the potential for variability in the fill materials used, the random nature of deposition of natural sediments, and the alteration of the original topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. 3. 1 Exploration Borings The exploration borings were completed by advancing a 3 lh-inch inside-diameter, hollow-stern auger with a truck-mounted drill rig. During the drilling process, sampling was conducted at depth intervals of approximately 5 feet. Subsurface conditions in the borings were May 14,2014 ASSOCIATED EARTH SCIENCES, INC. SSlld -KEl40J50AJ -Projecr.s120}4DJ50lKEIWP Page 2 N. 3(j' Street / Burnett Avenue N. Storm System Remon, Washington Subsurface Exploration and Geotechnical Engineering Report Proiec/ and Site Conditions continuously observed and logged by an engineering geologist from our firm. The exploration logs presented in Appendix A are based on the field logs, drilling action, and inspection of the samples obtained. Disturbed but representative samples were obtained by using the Standard Penetration Test (SPT) procedure in accordance with American Society for Testing and Materials (ASTM):D 1586. This test and sampling method consists of driving a standard, 2-inch outside-diameter, split-barrel sampler a distance of 18 inches into the soil with a 140-pound hammer free-falling a distance of 30 inches. During sampling, the number of blows for each 6-inch-depth interval is recorded and the number of blows required to drive the sampler over the 6-to 18-inch penetration is known as the Standard Penetration Resistance ("N") or blow count. If a total of 50 is recorded within one 6-inch interval, the blow count is recorded as the number of blows for the corresponding inches of penetration. The resistance, or N-value, provides a measure of the relative density of granular soils or the relative consistency of cohesive soils; these values are plotted on the attached boring logs. The samples obtained from the split-barrel sampler were classified in the field and representative portions placed in watertight containers. The samples were then transported to our laboratory for further visual classification and laboratory testing, as necessary. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the exploration borings accomplished for this study, our visual reconnaissance of the site, and review of applicable geologic literature. As shown on the exploration logs, the exploration borings advanced within the City's right-of-way generally encountered fill soils composed of very loose, granular sediments underlain by natural sediments consisting of medium dense to very dense sand. However, we expect that the subsurface conditions actually encountered along the aligmnent of the planned storm system within the roadway could encounter compacted trench backfill associated with several existing underground utilities. The following section presents more detailed subsurface information organized from the youngest to the oldest sediment types. 4.1 Stratigraphy Fill Soil interpreted to be fill was encountered within only boring EB-l to a depth of about 4 feet. The fill soil was comprised of very loose, fme sand with silt to silt with fine sand, and the gradation is similar to that of the underlying natural sediments. As previously mentioned, we May 14, 2014 ASSOCIATED EARTH SCIENCES, INC. SS/ld -KEl40J50A3 -ProjeC1s120J40J50IKEIWP Page 3 N. 30" Street / Burnett Avenue N. Storm System Renton. Washington Subsurface Exploration Qnd Geotechnical Engineering Repon Project Qnd Site Conditions anticipate that native or imported trench backfill soils may be encountered within the roadway where the new storm system is planned. Vashon Recessional Outwash Sediments encountered below the fill in boring EB-l and near the ground surface in EB-2 and EB-3 generally consisted of loose to medium dense, very moist to wet, brown fine sand with minor quantities of silt. We interpret these sediments to be representative of the Vashon recessional outwash. The Vashon recessional outwash consists of sediments that were deposited by meltwater streams that emanated from the retreating glacial ice during the latter portion of the Vashon Stade of the Fraser Glaciation, approximately 12,500 to 15,000 years ago. Vashon Lodgement Till Vashon lodgement till was encountered in exploration borings EB-l and EB-3 below the recessional outwash material. The till consisted of dense to very dense, moist to very moist, brown to gray sand with silt and few gravel. The lodgement till may contain cobble-and boulder-size rock at random locations. Several thousand feet of ice consolidated this material during the last (Vashon) glacial advance about 15,000 years ago. This resulted in a compact soil possessing high-strength, low-compressibility, and low-permeability characteristics. Vashon Advance Outwash Very dense, very moist to wet, brown, fine to coarse sand interpreted as advance outwash was encountered in exploration EB-3 below a depth of about 15 feet. These sediments were deposited by flowing water from the base of the southward advancing Vashon glacial front. The advance outwash has been overridden by several thousand feet of ice resulting in a very dense soil unit. 4.2 Laboratory Testing As discussed in Section 3.1, soil samples obtained from the split-barrel samplers from exploration borings EB-l through EB-3 were classified in the field and representative portions placed in watertight containers. The samples were then transported to our laboratory for further visual classification and laboratory testing, as necessary. Testing included moisture content ASTM:D 2216, and grain-size distribution ASTM:D 422. Laboratory test results are presented in Appendix B. May 14.2014 ASSOCIATED EARTH SCIENCES, INC.

Storm System Renton, Washington 4.3 Geologic Mapping Subsuiface Exploration and Geotechnical Engineering Report Proiect and Site Conditions Review of the regional geologic map titled Geologic Map of King County by Troost, Booth, and Wisher (May 2006) indicates that the area of the subject site is underlain by Vashon till and Vashon recessional outwash. Our interpretation of the sediments encountered in oUI explorations is in general agreement with the regional geologic map. 4.4 Hydrology Ground water seepage was encountered in borings EP-2 and EP-3 located on 30 th Street. In boring EB-2, a seepage zone was encountered at a depth of about 5 feet. In boring EB-3, seepage zones were encountered at depths of 5 and 15 feet below existing grades. It should be noted that the depth or occurrence of ground water seepage may vary in response to such factors as changes in season, precipitation, and site use. Our exploration was conducted in mid-April when ground water levels in unconfined aquifers in the Puget Lowland are typically at or near their seasonal high.

Storm System Renton, Washington Subsulface Exploration and Geotechnical Engineering Report Design Recommendations II. DESIGN RECOMMENDATIONS 5.0 INTRODUCTION Our explorations indicate that, from a geotechnical standpoint, the planned storm system replacement is feasible provided that the recommendations in this report are adhered to. The sediment type for the bulk of the trenching will likely be Vashon recessional outwash sediments or previously placed trench backfill along the storm system alignment. These materials will largely consist of sand with variable quantities of gravel and silt. Zones of ground water seepage were encountered in the borings located on N. 30" Street at depths ranging from 5 to 15 feet below existing grades. To determine the soil and ground water conditions within the proposed project alignment, AESI completed three exploration borings EB-J through EB-3. The borings were located as close as feasible to the proposed sewer alignment. Unfortunately. due to the presence of existing underground utilities and overhead power, our borings had to be located within the City's right-of-way and not within the roadway. As a result, we were unable to determine the current pavement section thickness for both roadways. Soil samples were collected from each boring and returned to our laboratory to complete testing on representative samples. 6.0 TRENCHING CONSIDERATIONS 6.1 Excavation The planned storm system replacement segment will be located along the centerline of the existing roadway areas. Therefore, it will be necessary to saw-cut the existing asphalt pavement prior to trenching operations. There will also be existing buried utilities that will complicate the excavation process, such as water and sewer. Overhead power lines are not expected to interfere with the planned construction, but along Burnett Avenue N., nearby tree limbs may limit the pick and swing radius of the trenching equipment. The installation of the storm system is expected to require open excavations approaching depths of 10 feet. In our opinion, stable construction slopes should be the responsibility of the contractor and should be determined during construction based on the local soil and ground water conditions encountered at the particular location at that time. However, it is assumed that the storm line trenches will be installed in a "neat line" trench with the use of a trench box (trench shield) rather than a large, open cut with the slopes laid back. The trench box should May 14, 2014 ASSOCIATED EARm SCIENCES, INC. SSlld -KEJ40150A3 -Projecrs1201401501KEIWP Page 6 N. 3(J' Street I Burnett Avenue N. Storm System Renton, Washington Subsurface Exploration and Geotechnical Engineering Report Design Recommendations be structurally certified. Laborers within the trench must remain within the trench box at all times, and WISHA/OSHA regulations should be followed at all times. We anticipate that soils encountered during the excavation process will provide moderate resistance to digging. Cobbles may be encountered during excavation within the recessional outwash unit. Cobbles and boulders could be present while trenching within the underlying glacial till unit. Ground water seepage, if present, into the trench can cause some caving/ sloughing to occur. The contractor should be experienced with excavating in moist to wet subgrade conditions. 6.2 Backfill The majority of the near-surface soils excavated from the trenches will likely be very moist to wet, fme to medium sand with gravel with variable silt contents. These soils are suitable for use as backfill material provided they are placed at or near (within 2 percent) optimum moisture contents. The backfill soils should be cleaned of organic materials and rocks larger than about 6 inches in nominal dimension. Ouring the wet season wet soils will not be suitable for backfill as its moisture content will likely be too far above optimum moisture for the soil to achieve suitable compaction. Import backfill will have to be used. Above the pipe zone bedding material, on-site soils may be used for backfill provided that they can be compacted to . at least 95 percent of the modified Proctor maximum dry. density, as defined by ASTM:O 1557. There are several options available, depending on the condition of the excavation, for trench backfill in lieu of the native soil. If the material excavated from the trench is not suitable for backfill due to high moisture or a high degree of deleterious material, imported backfill soil may be used and compacted to the required density. We recommend that the imported backfill consist of material conforming to Washington State Oepartment of Transportation (WSOOT) Standard Specification 9-03.14(1) "Gravel Borrow." If select import material is not available or if there is a need for a higher strength material, then controlled density fill (COF) should be used. COF consists of a mixture of water, sand, fly ash, and cement that will flow laterally to fill the voids from the caving. COF is available with varying amounts of cement, fly ash, and aggregate depending on the required compressive strength and flow characteristics. We recommend the use of a maximum 100 pounds per square inch (psi) compressive strength COF mix to facilitate future excavation and provide performance equivalent to well-compacted soil backfill. Trench backfill should be placed in uniform, horizontal lifts and compacted to the above standard. Thickness of structural backfill layers before compaction should not exceed 1 foot for the large, excavator-mounted, vibratory plate-type compactor. Smaller compaction equipment will require use of thinner lifts; hand-operated mechanical compactors should be May 14,2014 SSIId -KEJ40J50A3 -Projeas1201401501KEIWP ASSOCIATED EARm SCIENCES, INC Page 7 N. 30" Street / Burnett Avenue N. Storm System Renton, Washington Subswface Exploration and Geotechnical Engineering Report Design Recommendations used to compact lifts no thicker than 6 inches. Final lift thickness should be based on field performance testing using actual materials under field conditions and uniform compactive effort. In some cases, additional pipe zone bedding material above the pipe may be advisable to minimize required compactive effort needed to achieve the specified density in this area. 6.3 Pipe Bedding Pipe zone bedding material should be specified by the civil engineer following the pipe manufacturer's requirements. From a geotechnical standpoint, 31s-inch to 'Is-inch-size pea gravel would likely be suitable. Since the pipe will be laid at a relatively low gradient, uniform bedding material placement and compaction will be critical. Pipe bedding placement should conform to WSDOT Standard Specification 7-0S.3(1)C. 6.4 Pipe Subgrade The native soils are suitable for support of the pipe. In the event that soft or disturbed soils are encountered at the bottom of the trench, these soils may be overexcavated and replaced with structural backfill where it is encountered. An AESI representative should be on-site to observe subgrade conditions and document backfill operations. 7.0 DRAINAGE CONSIDERATIONS As discussed in Section 4.4, zones of ground water seepage were encountered in borings EB-2 and EB-3 located on N. 30'h Street at depths ranging from 5 to 15 feet below existing grades. It should be noted that the depth or occurrence of ground water seepage may vary in response to such factors as changes in season, precipitation, and site use. Our exploration was conducted in late April when ground water levels in unconfined aquifers in the Puget Lowland are typically at or near their seasonal high. We expect that ground water seepage can be managed by sump and pump methods and that formal dewatering wells will not be necessary. 8.0 EROSION HAZARDS AND MITIGATIONS The site consists of the existing developed roadways. Therefore, the erosion potential of the subject site is considered to be low under existing developed conditions. However, the erosion potential may increase temporarily during construction, especially if conventional cut and cover pipe construction is used. M<IJ 14, 2014 ASSOCIATED EARTH SCIENCES, INC. SSlld -KEJ40150A3 -Project.sI20140150lKE\WP Page 8 N. 3(fh Street / Burnett Avenue N. Storm System Renton, Washington Subsuiface Exploration and Geotechnical Engineering Report Design Recommendations Since the site will likely disrnrb less than I acre of aggregate area, the Washington State Department of Ecology (Ecology) Construction Storm Water General Permit (also known as the National Pollutant Discharge Elimination System [NPDES] permit) will likely not be required. However, to mitigate the erosion hazard potential, off-site sediment transport and rnrbid discharge into the existing storm water system, we would recommend the following minimum erosion control considerations in addition to the project temporary erosion and sedimentation control (TESC) plan: I. To the extent possible, earthwork-related construction should proceed during the drier periods of the year (typically April through October). Temporary erosion control measures should be maintained until permanent erosion control measures are established. 2. Pavement should remain in place to the extent possible to provide a suitable surface for staging and equipment access. Pavement areas should be swept with a vacuum sweeper truck frequently. 3. All catch basins within and adjacent to the construction area should be provided with filter socks to prevent siltation of the catch basin. 4. If excavated or imported soils have to be stockpiled on-site, they should be stored in such a manner as to reduce erosion and generation of rnrbid runoff during rainfall. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, and placing the stockpiles on plastic, with the plastic draped over perimeter straw wattle berms to contain any rnrbid runoff. 5. Disrnrbed areas should be paved or revegetated as soon as possible or otherwise protected. It is our opinion that with the proper implementation of the TESC plans and by field-adjusting appropriate mitigation best management practices (BMPs) throughout construction, as recommended by the above, erosion on the project can be suitably mitigated. 9.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, pipe installation techniques, shoring plans, and construction methods have not been completely finalized. We are available to provide additional geotechnical consultation as the project design develops and possibly changes from that upon which this report is based. We recommend that AESI perform a geotechnical review of the plans prior to May 14,2014 ASSOCIATED EARTH SCIENCES, INC.

In this way, implemented in the design. our recommendations may be properly interpreted and We are also available to provide geotechnical engineering and monitoring services during construction backfill operations. The integrity of the new pavement depends on proper site preparation and compaction procedures. In addition, engineering decisions may have to be made in the field in the event that variations in subsurface conditions become apparent. Construction monitoring services are not part of this current scope of work. If these services are desired, please let us know, and we will prepare a cost proposal.
