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: 1. Earth Impacts: The subject site is located in an area of known seismic hazards a geotechnical hazard. As such the applicant submitted a Preliminary Geotechnical Report, prepared by S&EE, dated March 18, 2017 (Exhibit 10) and an addendum to the report on May 22, 2017 (Exhibit 11). The analysis in the report primarily focused on the area near the Security Gate D -50 improvement due to the utility installation and regrading that will occur as part of the project. S&EE relied on the soil characteristics found in a previous boring, Boring B-2, at the same location less than two years ago for their analysis, as in their opinion, it is still representative of the s ubsurface conditions at the project site. The boring result indicated that the subsurface conditions at the site include fill over native soils. Fill ranged from about 10 to 11 feet in thickness and included sand, silty sand and silt. In general, the alluvial soils beneath the fill consist of a soft to medium dense silt and sand layer to a depth of about 30 feet, with dense to very dense sand and gravel below. Groundwater was encountered at a depth of 7 feet during the original drilling According to the City of Renton Critical Areas Maps the project site is located in a seismic hazard area. The provided Geotechnical Report addressed did not address seismic hazards due to the type of improvements being proposed (no new structures). The report continues to provide recommendations, including but not limited to, monitoring of subgrade preparation and trench backfill by the consultant, removal of loose soil cuttings prior to placement of bedding materials, using geotextile for additional subgrade stabilization, and proof- rolling pavement subgrades to determine unstable soils. The addendum was submitted at staff’s request for additional analysis to determine the feasibility of on-site infiltration. The addendum stated that onsite infiltration is not possible on the site due to the fill materials in place on top of the native soils. The applicant should follow the recommendations included in the provided geotechnical report or an updated geotechnical report at the time of project construction. The applicant has indicated the project would result in approximately 6,770 sq. ft. of replaced impervious area. Overall the project would not increase the imperious coverage on-site. Mitigation Measures: No further mitigation required. Nexus: Not applicable 2. Water a. Wetlands, Streams, Lakes Impacts: The project sites are located along the Cedar River, a Shoreline of the State. Reach A of the Cedar River Shoreline is designated as High Intensity at the project location. Due to two parts of the three part project being located within 200 feet of the OHWM of the Cedar River the applicant prepared a combination Standard Stream Study Narrative and a Habitat Data Report, prepared by AMEC Foster Wheeler, dated March 2017. The provided report primarily addresses the effects of the light relocation a part of the Gate D-50 improvements and potential effects on the fish and wildlife in the area. City of Renton Department of Community & Economic Development Environmental Review Committee Report BOEING LIFT STATION, GATE ENTRANCE, AND FUEL SPILL IMPROVEMENTS LUA17-000175, ECF, SM Report of June 29, 2017 Page 5 of 7 ERC REPORT 17-000175 No components of the subject projects would occur below the OHWM of the Cedar River. The applicant has proposed the relocation of two lights on the guard shack as part of the Gate D -50 improvement. The guard shack is located approximately 150 feet upland from the west bank of the Cedar River. The proposed lighting, located approximately 7 feet above grade, would be direc ted downward and away from the river. According to the study, the relocation of the two lights will not result in light impingement on the adjacent Lower Cedar River. Mitigation Measures: No further mitigation required. Nexus: Not applicable b. Storm Water Impacts: The applicant submitted a Technical Information Report (TIR) prepared by DOWL, dated May 2017, and revised the study May 2017 (Exhibit 12) Based on the updated TIR, the project contains greater than 2,000 SF of replaced impervious surface and ther efore Full Drainage Review is required pursuant to the 2017 City of Renton Surface Water Design Manual (RSWDW). Based on the City’s flow control map, this site falls within the Peak Rate Flow Control Standard matching Existing Site Conditions. A Full Drainage Review was included in the report. The project site is located within the Lake Washington and Cedar River Drainage basins. The flow - path from the project site discharge point is less than 0.5 miles from the 100-year floodplain of Lake Washington and therefore qualifies for the direct discharge exemption in accordance with Section 1.2.3.1 of the RSWDW and must adhere to all requirements thereof. The areas of the site improvements discharge to two separate threshold discharge areas that converge more than ¼ mile downstream. The combined surface area of new and/or replaced pollution generating impervious surface (PGIS) for each separate threshold discharge area of the improvements is less than 5,000 sq. ft. Therefore, the development is exempt from the requirement to provide water quality treatment prior to discharge for each separate threshold discharge area. On-site BMPs will be required to help mitigate the new runoff created by the proposed improvements. The final drainage report submitted at the time of construction permit application should address the implementation of on -site BMPs. This includes analyzing the feasibility of basic dispersion for the target impervious surface areas that may be able to disperse into added or existing landscaped areas. A Stormwater Pollution Prevention Plan (SWPPP) is required for this site and the final drainage plan and drainage report must be submitted with the utility construction permit application. Mitigation Measures: No further mitigation required. Nexus: No applicable 3. Trees and Vegetation Impacts: The submitted Stream Study and Habitat Report did not identify the presence of any trees or riparian vegetation in the project area. Therefore, the proposed improvements will not have any direct or indirect impacts to riparian vegetation or trees. Mitigation Measures: No further mitigation required. Nexus: Not applicable 4. Wildlife City of Renton Department of Community & Economic Development Environmental Review Committee Report BOEING LIFT STATION, GATE ENTRANCE, AND FUEL SPILL IMPROVEMENTS LUA17-000175, ECF, SM Report of June 29, 2017 Page 6 of 7 ERC REPORT 17-000175 Impacts: The project is located in an area of threatened species under the Endangered Species Act, the Puget Sound Chinook salmon and Puget Sound steelhead trout. In addition to the two threatened species WDFW Wildlife’s Priority Habitat and Species database identified five salmonid species that use the lower Cedar River, Chinook salmon, Coho salmon, Sockeye salmon, Steelhead, rainbow trout, and Coastal cutthroat trout. The provided Stream Study and Habitat Report includes a wildlife analysis for the section of the Cedar River in the project site vicinity (Exhibit 9). The entire project area is highly developed and disturbed. AMEC Foster Wheeler completed a qualitative assessment of the Cedar River Adjacent to the project site and found that the area provides very low habitat value and function due to the sparse riparian vegetation and extensive development along both banks of the river. The study continues to state that the project will not involve any in-water components or work below the OHWM, nor would any portion of the project occur in the riparian zone. The only portion of the project that could potentially affect aquatic biota is light impingement from the addit ional lighting proposed for the Apron project. The applicant has proposed the relocation of two lights on the guard shack as part of the Gate D -50 improvement. The lights will be relocated to positions under the new awnings on each side of the guard shack. The change in distance between the lights and the OHWM will be negligible. The guard shack is located approximately 150 feet upland from the west bank of the Cedar River. The proposed lighting, located approximately 7 feet above grade, would be directed downward and away from the river. According to the study, the relocation of the two will not result in light impingement on the adjacent Lower Cedar River. Mitigation Measures: No further mitigation required. Nexus: Not applicable 5. Historic and Cultural Preservation Impacts: In the SEPA checklist the applicant indicated that they completed a search of the Washington State Information System of Architectural and Archaeological Records Data. The Checklist concludes that the system did not identify any properties within the proj ect area as being on the historic property inventory or register. A letter received from the State Historic Preservation Officer on behalf of the Department of Archaeology and Historic Preservation (DAHP), dated June 28, 2017 (Exhibit 13), contained analysis and a recommendation related to the proposed improvements. The northern portion of the airport was once under the surface of Lake Washington. In addition the Black River used to run out of the lake, flow south through the airport and then west. Base d on the probability of the subject site being along the banks of an old river channel and lake shore there is a higher likelihood of cultural resources discovery, through ground disturbing activity. As such, staff recommends as a mitigation measure that if any Native American grave(s) or archaeological/cultural resources (Indian artifacts) are found all construction activity shall stop in accordance with RCW 27.53.060 and 27.44.020, and the owner/developer shall immediately notify the City of Renton planning department, concerned Tribes’ cultural committees, and the Washington State Department of Archeology and Historic Preservation. The SEPA check list indicates that if any archaeological resources are encountered a professional Archaeologist would be called to assess the significance of the find. Due to parts of the proposed project that would occur under the existing pervious surface, DAHP has recommended that the applicant hire a professional archeologist to monitor ground disturbing activities. In addition, DAHP recommended the applicant prepare an archaeological monitoring and City of Renton Department of Community & Economic Development Environmental Review Committee Report BOEING LIFT STATION, GATE ENTRANCE, AND FUEL SPILL IMPROVEMENTS LUA17-000175, ECF, SM Report of June 29, 2017 Page 7 of 7 ERC REPORT 17-000175 inadvertent discovery plan (MIDP) to be submitted to DAHP and the interested Tribes for review prior to any ground disturbance. Mitigation Measures: 1) If any Native American grave(s) or archaeological/cultural resources (Indian artifacts) are found all construction activity shall stop in accordance with RCW 27.53.060 and 27.44.020, and the owner/developer shall immediately notify the City of Renton planning department, concerned Tribes’ cultural committees, and the Washington State Department of Archeology and Historic Preservation. 2) The applicant shall submit an Archaeological Monitoring and Inadvertent Discovery Plan MIDP to DAHP and any interested Tribes for review prior to the start of any ground disturbing activities. Documentation of the submittal shall be provided to the City of Renton prior to the issuance of building or construction permits.

These practices include: Safety/ Environmental Pre-construction meeting The project will start with Boeing Environmental and Safety preconstruction to mitigate any risk associated with project Proposed Hauling/ Transportation routes Contractors will apply for their own hauling traffic control plans permits related to this project. And will follow a city approved route. Construction. The actual Construction will be accomplished by a Construction contractor. The contractor will call for all required inspections, as well as site pre-construction meeting. The contractor will keep records of any special inspections at the construction site  Flaggers will be used to reduce impacts  Activities will be scheduled during the City of Renton approved hours.  Dump trucks will have a cushion of sand to dampen loading noise.  Trucks will use trailers to reduce the number of trips.  Equipment will be shut off during standby activities to limit noise and exhaust.  Materials will be recycled to the extent possible minimizing debris, hauling and preservation of resources.  Activities will be overlapped as much as possible to shorted duration of overall construction duration. BOEING COMMERCIAL AIRPLANE GROUP RENTON WASHINGTON Storm Water - TECS Construction will start with the implementation and installation of Best Management Practices (BMP) for Temporary Erosion and Sedimentation Control (TESC) under supervision of Boeing Environmental personnel. All storm water drain inlets in and around the proposed construction operations and staging areas will be surrounded by oil absorbent padding to mitigate the potential of any hydraulic/fuel leakages emanating from construction machinery entering the watershed As a best management practice, any soil piles resulting from excavation activities will be covered with an impervious material, such as Vis -queen, to minimize and avoid erosion and to prevent silt from entering into the Cedar River Snow, Ice, dirt and mud removal Contractor shall remove snow and ice to the extent necessary to perform the work. The use of calcium chloride or other chemicals will not be permitted to remove snow or ice. Contractor shall assure that vehicles are constructed, loaded, maintained and covered as necessary to prevent the deposition of dirt, mud or other debris on public roadways. Dirt mud or debris shall be removed on continual basis. Any dirt, mud or debris dropped by vehicles shall be removed immediately. Dust Control Through the entire construction period the Contractor shall take all necessary steps to dust control all working area and unpaved roads. The use of calcium chloride or other chemicals will not be permitted for dust control. The Contractor will accomplish dust control by watering and sprinkling to satisfactorily settle the dust. Contractor shall comply with any requirements imposed by law to prevent fugitive dust emissions. All demolished materials and debris will be stockpiled on site to prevent dust and sedimentation from migrating onto roadways. Contractor vehicles that are transporting materials to and from the site will be required to have tires washed prior to leaving the site. This will prevent dust and sedimentation from entering nearby roadways. Airport Mitigation  A pre-construction meeting will set up with the Airport personnel.  The contractor will set up visual controls, and FOD controls including FOD fence.  Contractor will be in communication with airport tower during construction hours.  Contractor personnel will wear reflective vests on Airport apron at all times.

(S&EE) has been retained by you to perform a geotechnical evaluation for the above-referenced project. The project will involve re-configuration of the traffic flow through the existing D-50 gate. I understand that new underground electrical lines will be constructed, some minor re- grading will be performed, and new asphalt pavement will be installed. SURFACE AND SUBSURFACE CONDITIONS The project site is located in the southeastern portion of Renton Municipal Airport. Figure 1, which is included at the end of this report, shows the site location. The existing gate is surrounded by buildings, and the site surface is covered with asphalt pavement. The gate is accessed by East Perimeter Road which borders the west side of Cedar river and its levee. The site surface is relatively flat. S&EE performed a previous soil test boring, B-2, at the location shown in Figure 1. Based on our knowledge of soil conditions in the area, it is our opinion that the boring data are representative of the subsurface conditions at D-50 gate. The boring shows that the subsurface conditions at the site include fill over alluvial soils. The former is about 10 to 11 feet thick and consists of loose to medium dense silty sand, gravel and sand. The alluvial soils include a soft to medium dense silt and sand layer to a depth of about 30 feet, then dense to very dense sand and gravel below. This sand and gravel layer turns into a dense silty sand at a depth of 97.5 feet. Boring B-2 was terminated in this soil.

As a result of our review, our professional opinion is that the project area has a high probability to contain precontact archaeological resources. There are two precontact archaeological site recorded within approximately 3,500 feet of the project areas as well as precontact trail systems. There is a high potential for additional archaeological resources to be present. Please be aware that archaeological sites are protected from knowing disturbance on both public and private lands in Washington States. Both RCW 27.44 and RCW 27.53.060 require that a person obtain a permit from our Department before excavating, removing, or altering Native American human remains or archaeological resources in Washington. Failure to obtain a permit is punishable by civil fines and other penalties under RCW 27.53.095, and by criminal prosecution under RCW 27.53.090. Chapter 27.53.095 RCW allows the Department of Archaeology and Historic Preservation to issue civil penalties for the violation of this statute in an amount up to five thousand dollars, in addition to site restoration costs and investigative costs. Also, these remedies do not prevent concerned tribes from undertaking civil action in state or federal court, or law enforcement agencies from undertaking criminal investigation or prosecution. Chapter 27.44.050 RCW allows the affected Indian Tribe to undertake civil action apart from any criminal prosecution if burials are disturbed Since the project area is under impervious surface we recommend a professional archaeologist be present to monitor ground disturbing activities. We request that an archaeological monitoring and inadvertent discovery plan (MIDP) be prepared and submitted to DAHP and the interested Tribes for review prior to ground disturbance We also recommend consultation with the concerned Tribes' cultural committees and staff regarding cultural resource issues. If any federal funds or permits are associated with this proposal, Section 106 of the National Historic Preservation Act, as amended, and its implementing regulations, 36 CFR 800, must be followed. This is a separate process from both the NEPA and SEPA environmental review processes and requires formal government-to-government consultation with the affected Tribes and the SHPO. Also, we appreciate 2 receiving any correspondence or comments from concerned tribes or other parties concerning cultural resource issues that you receive. Thank you for the opportunity to comment on this project and we look forward to receiving the monitoring and inadvertent discovery plan (MIDP) report. Should you have any questions, please feel free to contact me. Sincerely, Gretchen Kaehler Assistant State Archaeologist, Local Governments (360) 586-3088 gretchen.kaehler@dahp.wa.gov cc.

Directly adjacent to the proposed replaced impervious area is the storm drain collection system for the area.  Project 2 is situated within a fully paved active apron. Activities on the apron include the use of environmentally hazardous chemicals and the transportation and loading of fuel onto aircraft.  Project 3 is situated within a fully paved parking area and is situated between an existing building and the adjacent property line. Water The site is located outside of an Aquifer Protection Area. Sewer Wastewater service is provided by the City of Renton.. The proposed project 3 includes replacement of an existing private sewer lift station owned and maintained by the applicant. Storm Runoff from the site is carefully collected monitored and processed through oil water separators before leaving the site through a larger interceptor system and ultimately discharged through a submerged pipe into Lake Washington . Boeing Lift Station, Gate Entrance, and Fuel Spill Project – LUA17-000175 Page 2 of 3 CODE REQUIREMENTS SEWER 1. The applicant shall provide verification from the design engineer that the replacement of the sewer lift station is designed in accordance with the current version of the Department of Ecology Orange Book. SURFACE WATER 1. A geotechnical report, dated March 18, 2017, completed by Soil & Environmental Engineers, Inc. (S&EE) for the site has been provided. The submitted report describes the site is a Low Erosion Hazard area. Erosion control measures will need to be in place prior to starting grading activities on the site. The report needs to discuss the soil and groundwater characteristics of the site including infiltration potential and provide recommendations for project design and construction. The report discounts the use of infiltration for the site based on the presence of fill materials in the upper 10-11 feet of soil. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated May 2017, was submitted by DOWL with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the Peak Rate Flow Control Standard area matching Existing Site Conditions and is within the Lake Washington and Cedar River Drainage Basin. The development is subject to Full Drainage Review in accordance with the 2017 City of Renton Surface Water Design Manual (RSWDM). All nine core requirements and the six special requirements are discussed in the Technical Information Report. 3. Direct Discharge Exception - The project site is located within the Lake Washington and Cedar River drainage basins and the flowpath from the project site discharge point is less than a half mile to the 100-year floodplain of Lake Washington and qualifies for the direct discharge exemption in accordance with Section 1.2.3.1 of the RSWDM and must adhere to all requirements thereof. 4. The project discharges to two separate threshold discharge areas which converge more than ¼- mile downstream of the respective project sites. The combined surface area of new and/or replaced pollution generating impervious surface (PGIS) for each separate threshold discharge area of the redevelopment project is less than 5,000 square feet. Therefore, the development is exempt from the requirement to provide water quality treatment prior to discharge for each separate threshold discharge area. 5. Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. The final drainage plan and drainage report, addressing the implementation of on- site BMPs must be submitted with the civil construction permit application. The applicant will need to re-evaluate the feasibility of utilizing basic dispersion for the target impervious surface areas that may be able to disperse into any added or existing landscaping areas. 6. A Construction Stormwater General Permit from Department of Ecology will be required if grading and clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan (SWPPP) is required for this site. 7. Surface water system development fee is $0.641 per square foot of new impervious surface, but not less than $1,608.00. This is payable prior to issuance of the construction permit. Boeing Lift Station, Gate Entrance, and Fuel Spill Project – LUA17-000175 Page 3 of 3 TRANSPORTATION 1. Parking lot reconstruction shall be in accordance with City code 4-4-80G. GENERAL COMMENTS 1. All existing and proposed utility lines (i.e. electrical, phone, and cable services, etc.) along property frontage or within the site must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Maximum exposed retaining wall height is 6-ft and shall be setback a minimum of 3-ft from the right-of-way as outlined in RMC 4-4-040 – Fences, Hedges and Retaining Walls. 3. Adequate separation between utilities as well as other features shall be provided in accordance with code requirements. a. 7-ft minimum horizontal and 1-ft vertical separation between storm and other utilities is required with the exception of water lines which require 10-ft horizontal and 1.5-ft vertical. b. The stormwater line should be minimum 5 feet away from any other structure or wall or building. c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building. 4. All civil construction permits for utility and street improvements will require separate plan submittals. All utility plans shall confirm to the Renton Drafting Standards. A licensed Civil Engineer shall prepare the civil plans. Please visit the Development Engineering Forms page for the most up-to-date plan submittal requirements: http://rentonwa.gov/business/default.aspx?id=42473 5. A landscaping plan shall be included with the civil plan submittal, if applicable. Each plan shall be on separate sheets. 6. Fees quoted in this document reflect the fees applicable in the year 2017 only and will be assessed based on the fee that is current at the time of the permit application or issuance, as applicable to the permit type.

Perimeter road and west of the Cedar River on Boeing leased airport property. Task one Replace sewer lift station near 4-42 Scope of Work The scope of work for this task involves replacement of Building 4 -42 sewage lift station. This lift station serves Building 4 -42, 4-41 and west side of Building 4-20. The new lift station shall be constructed and readied to place on line. During an outage, the sewer pipes shall be switched from the old lift station to the new lift station without impacting the building operations. Design of the new lift station shall take into effect the need to keep the buildings operational except for the switchover. Reroute existing fire line for new lift station The scope of work includes installation of a new vault for collection of sewage, two new submersible sewage pumps, controls and piping. A new 8” sewer line from sewage collected from Building 4-42 and 4-41 will be rerouted to the new 8 ft. sewage lift station vault. A 48” diameter manhole will be installed to collect the sewage upstream of the new vault The 4” discharge line from the new sewage pumps will be connected to the existing 4” sewage discharge line just south of the new lift station. The old sewage lift station will be demolished and filled in after the new lift station is put into service. Impervious surface disturbance is approx. 1900 sq. ft. ENVIRONMENTAL CHECKLIST 4 6/30/2017 Task Two Fuel spill containment Apron D Scope of Work The project will add a new fuel containment to the Boeing Apron D which is used for 737 Aircraft stalls.

These practices include: Safety/ Environmental Pre-construction meeting The project will start with Boeing Environmental and Safety preconstruction to mitigate any risk associated with project Proposed Hauling/ Transportation routes Contractors will apply for their own hauling traffic control plans permits related to this project. And will follow a city approved route. Construction. The actual Construction will be accomplished by a Construction contractor. The contractor will call for all required inspections, as well as site pre-construction meeting. The contractor will keep records of any special inspections at the construction site  Flaggers will be used to reduce impacts  Activities will be scheduled during the City of Renton approved hours.  Dump trucks will have a cushion of sand to dampen loading noise.  Trucks will use trailers to reduce the number of trips.  Equipment will be shut off during standby activities to limit noise and exhaust.  Materials will be recycled to the extent possible minimizing debris, hauling and preservation of resources.  Activities will be overlapped as much as possible to shorted duration of overall construction duration. BOEING COMMERCIAL AIRPLANE GROUP RENTON WASHINGTON Storm Water - TECS Construction will start with the implementation and installation of Best Management Practices (BMP) for Temporary Erosion and Sedimentation Control (TESC) under supervision of Boeing Environmental personnel. All storm water drain inlets in and around the proposed construction operations and staging areas will be surrounded by oil absorbent padding to mitigate the potential of any hydraulic/fuel leakages emanating from construction machinery entering the watershed As a best management practice, any soil piles resulting from excavation activities will be covered with an impervious material, such as Vis -queen, to minimize and avoid erosion and to prevent silt from entering into the Cedar River Snow, Ice, dirt and mud removal Contractor shall remove snow and ice to the extent necessary to perform the work. The use of calcium chloride or other chemicals will not be permitted to remove snow or ice. Contractor shall assure that vehicles are constructed, loaded, maintained and covered as necessary to prevent the deposition of dirt, mud or other debris on public roadways. Dirt mud or debris shall be removed on continual basis. Any dirt, mud or debris dropped by vehicles shall be removed immediately. Dust Control Through the entire construction period the Contractor shall take all necessary steps to dust control all working area and unpaved roads. The use of calcium chloride or other chemicals will not be permitted for dust control. The Contractor will accomplish dust control by watering and sprinkling to satisfactorily settle the dust. Contractor shall comply with any requirements imposed by law to prevent fugitive dust emissions. All demolished materials and debris will be stockpiled on site to prevent dust and sedimentation from migrating onto roadways. Contractor vehicles that are transporting materials to and from the site will be required to have tires washed prior to leaving the site. This will prevent dust and sedimentation from entering nearby roadways. Airport Mitigation  A pre-construction meeting will set up with the Airport personnel.  The contractor will set up visual controls, and FOD controls including FOD fence.  Contractor will be in communication with airport tower during construction hours.  Contractor personnel will wear reflective vests on Airport apron at all times.

The existing gate is surrounded by buildings, and the site surface is covered with asphalt pavement. The gate is accessed by East Perimeter Road which borders the west side of Cedar river and its levee. The site surface is relatively flat. S&EE performed a previous soil test boring, B-2, at the location shown in Figure 1. Based on our knowledge of soil conditions in the area, it is our opinion that the boring data are representative of the subsurface conditions at D-50 gate. The boring shows that the subsurface conditions at the site include fill over alluvial soils. The former is about 10 to 11 feet thick and consists of loose to medium dense silty sand, gravel and sand. The alluvial soils include a soft to medium dense silt and sand layer to a depth of about 30 feet, then dense to very dense sand and gravel below. This sand and gravel layer turns into a dense silty sand at a depth of 97.5 feet. Boring B-2 was terminated in this soil.

Box 48343 • Olympia, Washington 98504-8343 • (360) 586-3065 www.dahp.wa.gov June 28, 2017 Mr. Alex Morganroth Associate Planner City of Renton 1055 South Grady Way Renton, WA98057 In future correspondence please refer to: Project Tracking Code: 2017-06-04599 Property: LUA17-000175, ECF, SM Boeing Lift Station, Gate Entrance and Fuel Spill Re: Archaeology – Professional Archaeological Monitor and Monitoring Plan Requested Dear Mr. Morganroth: Thank you for contacting the Washington State Historic Preservation Officer (SHPO) and Department of Archaeology and Historic Preservation (DAHP) and providing documentation regarding the above referenced project. As a result of our review, our professional opinion is that the project area has a high probability to contain precontact archaeological resources. There are two precontact archaeological site recorded within approximately 3,500 feet of the project areas as well as precontact trail systems. There is a high potential for additional archaeological resources to be present. Please be aware that archaeological sites are protected from knowing disturbance on both public and private lands in Washington States. Both RCW 27.44 and RCW 27.53.060 require that a person obtain a permit from our Department before excavating, removing, or altering Native American human remains or archaeological resources in Washington. Failure to obtain a permit is punishable by civil fines and other penalties under RCW 27.53.095, and by criminal prosecution under RCW 27.53.090. Chapter 27.53.095 RCW allows the Department of Archaeology and Historic Preservation to issue civil penalties for the violation of this statute in an amount up to five thousand dollars, in addition to site restoration costs and investigative costs. Also, these remedies do not prevent concerned tribes from undertaking civil action in state or federal court, or law enforcement agencies from undertaking criminal investigation or prosecution. Chapter 27.44.050 RCW allows the affected Indian Tribe to undertake civil action apart from any criminal prosecution if burials are disturbed Since the project area is under impervious surface we recommend a professional archaeologist be present to monitor ground disturbing activities. We request that an archaeological monitoring and inadvertent discovery plan (MIDP) be prepared and submitted to DAHP and the interested Tribes for review prior to ground disturbance We also recommend consultation with the concerned Tribes' cultural committees and staff regarding cultural resource issues. If any federal funds or permits are associated with this proposal, Section 106 of the National Historic Preservation Act, as amended, and its implementing regulations, 36 CFR 800, must be followed. This is a separate process from both the NEPA and SEPA environmental review processes and requires formal government-to-government consultation with the affected Tribes and the SHPO. Also, we appreciate 2 receiving any correspondence or comments from concerned tribes or other parties concerning cultural resource issues that you receive. Thank you for the opportunity to comment on this project and we look forward to receiving the monitoring and inadvertent discovery plan (MIDP) report. Should you have any questions, please feel free to contact me. Sincerely, Gretchen Kaehler Assistant State Archaeologist, Local Governments (360) 586-3088 gretchen.kaehler@dahp.wa.gov cc.

Directly adjacent to the proposed replaced impervious area is the storm drain collection system for the area.  Project 2 is situated within a fully paved active apron. Activities on the apron include the use of environmentally hazardous chemicals and the transportation and loading of fuel onto aircraft.  Project 3 is situated within a fully paved parking area and is situated between an existing building and the adjacent property line. Water The site is located outside of an Aquifer Protection Area. Sewer Wastewater service is provided by the City of Renton.. The proposed project 3 includes replacement of an existing private sewer lift station owned and maintained by the applicant. Storm Runoff from the site is carefully collected monitored and processed through oil water separators before leaving the site through a larger interceptor system and ultimately discharged through a submerged pipe into Lake Washington . Boeing Lift Station, Gate Entrance, and Fuel Spill Project – LUA17-000175 Page 2 of 3 CODE REQUIREMENTS SEWER 1. The applicant shall provide verification from the design engineer that the replacement of the sewer lift station is designed in accordance with the current version of the Department of Ecology Orange Book. SURFACE WATER 1. A geotechnical report, dated March 18, 2017, completed by Soil & Environmental Engineers, Inc. (S&EE) for the site has been provided. The submitted report describes the site is a Low Erosion Hazard area. Erosion control measures will need to be in place prior to starting grading activities on the site. The report needs to discuss the soil and groundwater characteristics of the site including infiltration potential and provide recommendations for project design and construction. The report discounts the use of infiltration for the site based on the presence of fill materials in the upper 10-11 feet of soil. Geotechnical recommendations presented need to be address within the project plans. 2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated May 2017, was submitted by DOWL with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the Peak Rate Flow Control Standard area matching Existing Site Conditions and is within the Lake Washington and Cedar River Drainage Basin. The development is subject to Full Drainage Review in accordance with the 2017 City of Renton Surface Water Design Manual (RSWDM). All nine core requirements and the six special requirements are discussed in the Technical Information Report. 3. Direct Discharge Exception - The project site is located within the Lake Washington and Cedar River drainage basins and the flowpath from the project site discharge point is less than a half mile to the 100-year floodplain of Lake Washington and qualifies for the direct discharge exemption in accordance with Section 1.2.3.1 of the RSWDM and must adhere to all requirements thereof. 4. The project discharges to two separate threshold discharge areas which converge more than ¼- mile downstream of the respective project sites. The combined surface area of new and/or replaced pollution generating impervious surface (PGIS) for each separate threshold discharge area of the redevelopment project is less than 5,000 square feet. Therefore, the development is exempt from the requirement to provide water quality treatment prior to discharge for each separate threshold discharge area. 5. Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. The final drainage plan and drainage report, addressing the implementation of on- site BMPs must be submitted with the civil construction permit application. The applicant will need to re-evaluate the feasibility of utilizing basic dispersion for the target impervious surface areas that may be able to disperse into any added or existing landscaping areas. 6. A Construction Stormwater General Permit from Department of Ecology will be required if grading and clearing of the site exceeds one acre. A Stormwater Pollution Prevention Plan (SWPPP) is required for this site. 7. Surface water system development fee is $0.641 per square foot of new impervious surface, but not less than $1,608.00. This is payable prior to issuance of the construction permit. Boeing Lift Station, Gate Entrance, and Fuel Spill Project – LUA17-000175 Page 3 of 3 TRANSPORTATION 1. Parking lot reconstruction shall be in accordance with City code 4-4-80G. GENERAL COMMENTS 1. All existing and proposed utility lines (i.e. electrical, phone, and cable services, etc.) along property frontage or within the site must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton inspector. 2. Maximum exposed retaining wall height is 6-ft and shall be setback a minimum of 3-ft from the right-of-way as outlined in RMC 4-4-040 – Fences, Hedges and Retaining Walls. 3. Adequate separation between utilities as well as other features shall be provided in accordance with code requirements. a. 7-ft minimum horizontal and 1-ft vertical separation between storm and other utilities is required with the exception of water lines which require 10-ft horizontal and 1.5-ft vertical. b. The stormwater line should be minimum 5 feet away from any other structure or wall or building. c. Trench of any utility should not be in the zone of influence of the retaining wall or of the building. 4. All civil construction permits for utility and street improvements will require separate plan submittals. All utility plans shall confirm to the Renton Drafting Standards. A licensed Civil Engineer shall prepare the civil plans. Please visit the Development Engineering Forms page for the most up-to-date plan submittal requirements: http://rentonwa.gov/business/default.aspx?id=42473 5. A landscaping plan shall be included with the civil plan submittal, if applicable. Each plan shall be on separate sheets. 6. Fees quoted in this document reflect the fees applicable in the year 2017 only and will be assessed based on the fee that is current at the time of the permit application or issuance, as applicable to the permit type.
