Please refer to the Vicinity Map within this section for a depiction of the project site. The project site is currently an undeveloped grassed area just west of an existing parking lot. The surrounding properties are the Boeing Building 25-01 to the north, Oakesdale Avenue Southwest to the east, vacant land owned by Boeing to the south, and existing stormwater ponds and mitigated wetlands to the west. According to the City of Renton soils maps, the on-site soils consist of Puget Silty Clay Loam, also known as till soils. The site is located within the 100-year floodplain per current adopted FIRM mapping. No regulated wetlands currently exist on site. The site is also located within a Seismic Hazard Area according to the City of Renton mapping. The project area drains to the north through an existing 12-inch culvert to existing stormwater ponds that were constructed as a part of the Boeing Company Surface Water Management Project in 1999. The site is within the Black River Basin, also a part of the Duwamish-Green watershed. The parking lot expansion area will incorporate permeable paving to provide stormwater treatment, storage, and infiltration. WWHM was used to model the permeable pavement section. The 8-inch base will provide stormwater storage, while the stormwater infiltrates into the underlying soils. Surface runoff from the permeable pavement is not anticipated and will only occur in the event that the porous asphalt pores get clogged or a storm event that exceeds the 100 year model. The permeable pavement section has been modeled to infiltrate the entire 100-year developed storm event. The parking area expansion will minimize impacts to the existing floodplain and will not reduce the effective storage volume within the floodplain. The onsite stormwater facilities will be designed in accordance with the 2009 King County Surface Water Design Manual (KCSWDM), 2012 Low Impact Development Technical Guidance Manual for Puget Sound, and the City of Renton Amendments to the KCSWDM. The Seattle Pipe Trades Addition is located at the Seattle Pipe Trades facility in the City of Renton Washington at 595 Monster RD SW and lies within Section 24, Township 23 North, Range 4 East. Please refer to the Vicinity Map within this section for a depiction of the project site. Seattle Area Pipe Trades is proposing to add an 11,900SF addition to the current 53,400sf Building on the south side of the building located at 595 Monster Rd SW Renton, WA 98057 Parcel 240324-9122 County of King, State of Washington. This will require relocation of some utilities and expansion of parking to the south of the 5.53 Acre Site. The neighboring property Owner has agreed to sell additional area and/or possibly grant construction and slope easements to allow additional parking to be developed. According to the City of Renton soils maps, the on-site soils consist of Puget Silty Clay Loam, however the Geotech Report indicates alluvial soils in the area of pavement so we have modeled this as outwash A/B . The site is located within the 100-year floodplain per current adopted FIRM mapping. No regulated wetlands currently exist on site. The site is also located adjacent to a Seismic Hazard Area according to the City of Renton mapping. The project area drains to the north through an existing 12-inch culvert to existing stormwater ponds that were constructed as with the original building construction. The site is within the Green River Basin, also a part of the Duwamish-Green watershed. The parking lot expansion area will incorporate permeable paving to provide stormwater treatment, storage, and infiltration. WWHM was used to model the permeable pavement section. The 8-inch base will provide stormwater storage, while the stormwater infiltrates into the underlying soils. Surface runoff from the permeable pavement is not anticipated and will only occur in the event that the porous asphalt pores get clogged or a storm event that exceeds the 100 year model. The permeable pavement section has been modeled to infiltrate the entire 100-year developed storm event. The parking area expansion will minimize impacts to the existing floodplain and will not reduce the effective storage volume within the floodplain. The onsite stormwater facilities will be designed in accordance with the 2009 King County Surface Water Design Manual (KCSWDM), 2012 Low Impact Development Technical Guidance Manual for Puget Sound, and the City of Renton Amendments to the KCSWDM. We have designed and verified the facilities using the WWHM2012 analysis tools according to the Washington Department of Ecology WWHM2012 amended in DEC 2014. Criteria is Peak Rate Flow Control matching existing flows. Page 2 2.0 CONDITIONS AND REQUIREMENTS SUMMARY The project is subject to Full Drainage Review as dictated by the KCSWDM and the City of Renton Amendments to the KCSWDM. Core Requirements No. 1 through 8 and Special Requirements No. 1 through 5 are described below: 2.1 Analysis of the Eight Core Requirements Core Requirement No. 1: Discharge at the Natural Location. The intent of this requirement is to “prevent adverse impacts to downstream properties caused by diversion of flow from one flowpath to another, and to discharge in a manner that does not significantly impact downhill properties or drainage systems,” KCWSWDM pages 1-19. The existing site drains to northerly to the existing onsite stormwater facilities and is then conveyed easterly into Springbrook Creek. The ultimate discharge location for the site will remain unchanged. Stormwater runoff will be infiltrated with the use of permeable paving. Core Requirement No. 2: Off-Site Analysis. The intent of this requirement is to identify and evaluate off-site flooding and erosion problems that may be created or aggravated by the proposed project and to ensure appropriate measures are provided for preventing creation or aggravation of those problems. This project is proposing to infiltrate stormwater runoff with the use of permeable paving. This will result in lower peak flows from the site; therefore, no off-site flooding or erosion problems will be created or aggravated by this project. Based on these conditions, an offsite analysis is not required. Core Requirement No. 3: Flow Control. The intent is to ensure the minimum level of control needed to protect downstream properties and resources from increases in peak, duration, and volume of runoff generated by new development. This site is located within a Peak Rate Flow Control zone according to the City of Renton flow control map. A reduction in peak flows is expected as a result of the development. This is because the proposed permeable paving system will infiltrate of all stormwater runoff within the development area. Core Requirement No. 4: Conveyance System. The intent of this requirement is to ensure proper design and construction of engineered conveyance system elements. New conveyance systems are designed to convey the developed 100-year peak storm event. The existing site drains to northerly to the existing onsite stormwater facilities and is then conveyed southwesterly to Green River. The ultimate discharge location for the site will remain unchanged. Stormwater runoff will be infiltrated with the use of permeable paving. There is no discharge from the pavement to any underground conveyance systems. The new building addition will discharge to the 12" conveyance pipes which are relocated around the addition resulting in less flow due to the elimination of the existing parking lot flow to the existing CB's and Private Storm Conveyance System. See the analysis that occurs follows under the WWHM Calcs Section. Page 3 Core Requirement No. 5: Temporary Erosion and Sediment Control. The intent of this requirement is to prevent the transport of sediment and other impacts, such as increased runoff, related to land disturbing activities. A Temporary Erosion and Sedimentation Control (TESC) Plan has been prepared as part of the Civil Plan Set. The TESC Plan will control the transport of sediment to downstream surface waters and adjacent properties in accordance with all the applicable standards of the KCWSWDM and the City of Renton. Core Requirement No. 6: Maintenance and Operations. The intent is to ensure that the maintenance responsibility for drainage facilities is clearly assigned and that these facilities will be properly maintained and operated in perpetuity. Operations and Maintenance instructions are included in Section 10.0. Core Requirement No. 7: Financial Guarantees and Liability. This requirement is intended to ensure financial guarantees are posted to sufficiently cover the cost of correcting, if necessary, incomplete or substandard drainage facility construction work, and to warrant for two years the satisfactory performance and maintenance of those newly-constructed drainage facilities to be assumed by the City of Renton for maintenance and operation. All applicable guarantees will be provided for the project. The bond quantities are included in Section 9.0 of this report. Core Requirement No. 8: Water Quality. The intent of the water quality requirement is "to require an efficient, cost- effective level of water quality treatment tailored to the sensitivities and resource protection needs of the downstream receiving water to which the project site drains." and "Core Requirement No. 8 requires that water quality treatment facilities be provided to remove pollutants from runoff discharging from the project site." Stormwater treatment will be provided via a soil treatment layer beneath the permeable paving section. 2.2 Analysis of the Five Special Requirements Special Requirement No. 1: Other Adopted Area-Specific Requirements. The following is a list of other possible adopted area-specific requirements according to the KCWSWDM: Critical Drainage Areas – This development is not located within a critical drainage area. All new and replaced paving will be permeable asphalt with infiltration and WQ filtration. See soils report for soils characteristics and Section 4.0 below. Thus the PGIS area is reduced from existing roughly 22,000sf. See areas in the Exhibits. No sediment runoff shall go outside project limits during construction. Stormwater flow control BMP Covenant draft is provided in this TIR. Six Page 4 Master Drainage Plan – The area is not part of a master drainage plan. Basin Plans – This project does not fall into any specified basin plan. Salmon Conservation Plan – A Salmon Conservation Plan does not apply to this development. Lake Management Plan – It does not appear that there is a Lake Management Plan that impacts the proposed development. Flood Hazard Reduction Plan Updates – It does not appear that the flood hazard reduction plan adversely affects the proposed development. Shared Facility Drainage Plan – The project does not propose to connect to a shared detention facility system or create a shared facility. This plan does not apply. Special Requirement No. 2: Flood Hazard Area Delineation. The proposed site is located within the 100-year floodplain of Springbrook Creek. The base flood elevation identified by FEMA is approximately 19.0 (datum in NGVD 29). Based on a review of current survey information, the 100-year floodplain corresponds to elevation 22.5 (datum in NAVD 88). Please refer to the included FIRM map. Special Requirement No. 3: Flood Protection Facilities. Special Requirement No. 3 is not applicable to the proposed site because the site does not meet either of the conditions set forward in the 2009 KCWSWDM: · Contains or is adjacent to a Class 1 or 2 stream that has an existing flood protection facility (such as a levee, revetment, or berm). · Proposed to construct a new or to modify an existing flood protection facility. The design of the site will not affect any existing flood protection facilities. Special Requirement No. 4: Source Control. Special Requirement No. 4 will be met through a variety of on-site source control BMPs. This includes the good housekeeping practices and maintenance. Special Requirement No. 5: Oil Control. The proposed parking area is not classified as a high use site as defined in the KCSWDM. Special Requirement No. 6: Aquifer Protection AreaNot applicable. FEMA elevation certificate is required for building addition. Page 5 3.0 OFF-SITE ANALYSIS 3.1 Upstream Drainage There is an upstream basin of approximately 1.3-acres that drains to the project site. The upstream area will be collected and routed around the proposed parking lot expansion and is therefore considered negligible and has no impact on the proposed development. 3.2 Downstream Drainage Course The existing downstream drainage course for the project area starts at the existing 12-inch culvert at the northern portion of the project site. This culvert conveys flows to the north and runoff then flows to the northwest into the existing storm drainage and mitigated wetland system. Runoff then flows to the east in a series of culverts and ditches, until entering Springbrook Creek approximately one half mile downstream from the project site. This project is proposing to infiltrate stormwater runoff from the proposed parking expansion area with the use of permeable pavement. Infiltration of stormwater runoff will result in a reduction of peak flows to the downstream area; therefore, no off-site flooding or erosion problems will be created or aggravated by this project. Based on these conditions, an offsite analysis is not required. There is no uptream drainage onto the site. Drainage off the hillside to the south drains to the existing seasonal pond that is offsite. We maintain the runoff from this hillside to it's natural direction. Existing Drainage from the Building and parking lot is collected into a system of 12" storm drains and Catch Basins and conveyed to the North to a Storm Facility then southwesterly to a Regional Pump Station where it is pumped to the River. This project is proposing to infiltrate stormwater runoff from the proposed parking expansion area with the use of permeable pavement. Infiltration of stormwater runoff will result in a reduction of peak flows to the downstream area; therefore, no off-site flooding or erosion problems will be created or aggravated by this project. Based on these conditions, an offsite analysis is not required. The expanded parking area will be Permeable Pavement and infiltrate. Page 6 4.0 ANALYSIS AND DESIGN 4.1 Existing Site Hydrology According to the City of Renton soils maps, the on-site soils consist of Puget Silty Clay Loam, also known as till soils. The site is has slopes ranging from 1 percent to 3 percent, tending to the north. The site is currently a vacant grassed area. Per the City of Renton Amendment to the KCSWDM, the existing site conditions are those that existed prior to 1979. During that time, the site existed as a portion of the Longacres Racetrack per aerial photography and has been modeled as till grass. Please see Pre-Developed Basin Map for the existing site conditions. Runoff from the predeveloped site sheet flows northerly until entering a 12-inch culvert, is then conveyed to the northwest into the existing stormwater system, and eventually discharges into Springbrook Creek one half mile downstream from the site. The predeveloped peak flows are as follows (from WWHM output): Q2= 0.095 cfs Q10= 0.236 cfs Q100= 0.494 cfs 4.2 Developed Site Hydrology The proposed construction of the parking lot, sidewalk and internal landscaping will utilize permeable paving to infiltrate stormwater runoff. The proposed improvements cover approximately 1.21-acres of the site. The site will be graded within a 1.5 percent slope to the west. An interceptor swale will be constructed along the west to intercept any runoff that may occur during an emergency event (i.e. soil saturation or permeable pavement failure). The existing land use cover was modeled as till grass. The geotechnical report by Geo Engineers found that the factored underlying soils support a 0.25 inches/hour infiltration rate. Please see the Developed Conditions Exhbit. Site Area = 1.21 acres Assume all is permeable pavement = 1.21 acres Pervious Area (landscaping) will infiltrate into the permeable subsurface therefore will be modeled as permeable pavement Assuming that infiltration is not possible the peak flows would be: Q2= 0.54 cfs Q10= 0.78 cfs The existing Parking Lot drains to existing Catch Basins and 12" Storm Drains that convey the water to the north to the facility constructed for the existing building. The railroad spur and area south of the Site currently drain to the south to a seasonal swale and pond. The expansion to the south as well as replacement of existing pavement will be regraded to avoid impacts to the floodwater volumes and impervious areas replaced with pervious asphalt pavement to provide water quality treatment and infiltration for groundwater recharge, an LID, Low Impact Development Technique. The wetland is identified and classified along with the 25ft buffer as shown on the plans. No work to be done within this buffer or wetland. 4.2 Developed Site Hydrology The area to the south of the existing parking is landscaped area and will be parking area with pervious asphalt and landscaping. Page 7 Q100= 1.11 cfs 4.3 Flow Control Permeable paving, a Low Impact Development (LID) technique, is proposed to mitigate for the increased stormwater from new impervious surfaces constructed on site. The permeable pavement section has been modeled with WWHM 2012, which has the ability to model permeable pavement. The in accordance with the KCSWDM guidance and will infiltrate the full developed 100-year peak storm event. The permeable paving section was modeled over the entire area. The permeable paving layer thickness is 0.25 feet with a pavement porosity of 0.20 or 20 percent. The choker course thickness is 0.17 feet and has an assumed 0.20 porosity. The base course (storage) is 0.67 feet and has a conservative 0.30 porosity or 30 percent voids within the aggregate base storage bed. The soil layer was modeled with a 0.25 inch/hour infiltration to be confirmed by the Geo Engineers. The modeled permeable pavement basin will infiltrate 100 percent of storm event. 4.4 Water Quality This site is subject to Enhanced Basic Water Quality treatment since it is a commercial property. The site is exempt from providing a traditional water quality treatment facility since the project’s stormwater runoff will be infiltrated into subsurface soils. The subsurface soils will act as a soil treatment layer, which meet the groundwater protection criteria per the City of Renton Surface Water Design Manual Amendment. The criteria are outlined as follows: 1) The first 2 feet or more of soil beneath the infiltration facility has a cation exchange capacity greater than 5 and an organic content of greater than 0.5%, AND 2) The soil must have a measured infiltration rate of less than or equal to 12 inches per hour. The project will infiltrate 100 percent of the stormwater runoff into the subsurface soils, which meets the treatment criteria. Please refer to the calculations within this section and included soil reports in Section 6.0 for values regarding cation exchange, organic content, and infiltration rates. 4.5 Flood Plain Review of the King County Flood Insurance Rate Map (Firm) #53033C0976 F, found that the site is within the 100-year flood Zone AH. Much of the site is below the 100-year flood elevation contour of 19.0. The site will be graded to minimize Permeable paving, a Low Impact Development (LID) technique, is proposed to mitigate for the increased stormwater from new paving constructed on site. The permeable pavement section has been modeled with WWHM 2012, which has the ability to model permeable pavement. This is in accordance with the KCSWDM guidance and will infiltrate the full developed 100-year peak storm event. Technically, there is less impervious area and reduced PGIS that exempts this project however the development was modeled to prove the results. The permeable paving section was used over the entire area of new pavement. There are two Points of Compliance shown on the maps below and each analyzed. The modeled permeable pavement basin will infiltrate 100 percent of storm event and both points of compliance pass. Page 8 impact within the flood plain. We have created additional floodwater volume by excavating into the hillside to the south. Volumes below the flood plain (elev=22.58'): EG = 1394 CF FG = 1313 CF Thus the new grades created additional Flood Plain Volume. PROPOSED GRADING MODEL EXISTING GRADING MODEL impact within the flood plain. We have created additional floodwater volumeby excavating into the hillside to the south.

No new flow to conveyance systems or pipes are a part of this proposal. Existing upstream flow is rerouted around the new building addition and the flow to the moved CB's now infiltrates through the PAP. Thus the flow in the pipes is reduced but the size remains the same as the existing.No increase in flow characteristics for the Private Stormwater system. Existing pipes are 12" diameter.

Confirm. City please confirm. willConstruction Stormwater General Permit (Department of Ecology) may be needed as the total cleared area is about one acre. Owner and Contractor have applied for a waiver from DOE. They likely will receive a waiver as the work is planned for the summer months and the area of clearing in total is just over the limit. Application is attached below. · SEPA Environmental Review · Land Surface Modification (grading) Permit · Drainage Plan Review · Clearing and Grading Permit Page 12 8.0 ESC ANALYSIS AND DESIGN TESC measures are put into place to prevent sediment from leaving the site. The site is generally flat. The proposed TESC plan will include, but not be limited to, the following guidelines set in the 2009 KCWSWDM in order to comply with Core Requirement No. 5. 1. Clearing Limits – Clearing limits specify the boundary of the work to be done. Clearing are defined on the TESC plans and will be flagged in the field. 2. Cover Measures – Cover measures are involved (typically) with the means to control erosion of exposed soil and are specified on the TESC plans. 3. Perimeter Protection – Perimeter protection keeps site sediment from leaving the construction site. This type of protection typically involves a silt fence. The silt fence and clearing limits are shown on the TESC plans. 4. Traffic Area Stabilization – Traffic area stabilization is addressed by a stabilized construction entrance. 5. Sediment Retention – Retention will be established by silt fences around the perimeter and catch basin inserts that will control of the on-site sediment-laden water. 6. Surface Water Collection – An interceptor ditch with check dams is shown in the plans and will be implemented in the field if necessary. 7. Dewatering Control – Any water from dewatering shall be filtered or contained so sediment can filter out prior to discharge downstream. 8. Dust Control – Dust control will be provided by sprinkling. 9. Wet Season Construction – Construction will be conducted according to the City of Renton standards during the wet season. 10. Construction Within Sensitive Areas and Buffers - Any construction within the wetland buffer will be subject to sensitive areas restrictions and is contained in the TESC notes. 11. Maintenance – Maintenance requirements are detailed in the TESC notes within the engineering plans. 12. Final Stabilization – Upon completion of the project, all disturbed areas will be stabilized and Best Management Practices removed.

Maintenance of the onsite drainage facilities are limited to maintaining the permeable pavement parking lot and the adjacent ditch, conveyance pipe and pipe inlet trash rack. Existing Pipe and Conveyance Systems Please see the following Maintenance requirements No. 6 – Conveyance Pipes and Ditches and No. 7 – Debris Barriers (i.e. Trash Racks). Permeable Pavement The primary goal of porous pavement maintenance is to prevent the pavement surface and/or the underlying infiltration bed from being clogged with fine sediments. To keep the system clean throughout the year and prolong its lifespan, the pavement surface should be vacuumed biannually with a commercial cleaning unit. All inlet structures within or draining to the infiltration beds should also be cleaned out on a biannual basis. Planted areas adjacent to porous pavement should be well maintained to prevent soil washout onto the pavement. If any washout does occur it should be cleaned off the pavement immediately to prevent further clogging of the pores. Furthermore, if any bare spots or eroded areas are observed within the planted areas, they should be replanted and/or stabilized at once. Planted areas should be inspected on a semi-annual basis. All trash and other litter that is observed during these inspections should be removed. Superficial dirt does not necessarily clog the pavement voids. However, dirt that is ground in repeatedly by tires can lead to clogging. Therefore, trucks or other heavy vehicles should be prevented from tracking or spilling dirt onto the pavement. Furthermore, all construction or hazardous materials carriers should be prohibited from entering a porous pavement lot. Winter Maintenance Winter maintenance for a porous parking lot may be necessary, but is usually less intensive than that required for a standard asphalt lot. By its very nature, a porous pavement system with subsurface aggregate bed has superior snow melting characteristics than does standard pavement. Therefore, ice and light snow accumulation are generally not as problematic. However, snow will accumulate during heavier storms. Abrasives such as sand or cinders should not be applied on or adjacent to the porous pavement. Snow plowing is necessary for significant snow accumulation, but should be done carefully (i.e. by setting the blade slightly higher than usual, about an inch). Standard road salt is acceptable for use as a deicer on porous pavement, although a non-toxic, organic deicer, applied either as a blended, magnesium chloride- based liquid product or as pretreated rock salt, is recommended. Please consult local governmental agency for an acceptable deicer.

Printed name Notary Public in and for the State of Washington, residing at My appointment expires Exhibit A Exhibit B PERMEABLE PAVEMENT MAINTENANCE INSTRUCTIONS Your property contains a stormwater management flow control BMP (best management practice) called"permeable pavement," which was installed to minimize the stormwater quantity and quality impacts ofsome or all of the paved surfaces on your property. Permeable pavements reduce the amount of rainfallthat becomes runoff by allowing water to seep through the pavement into a free-draining gravel or sandbed, where it can be infiltrated into the ground. Permeable PavementThe type(s) of permeable pavement used on your property is: porous asphaltic concrete, The area covered bypermeable pavement as depicted by the flow control BMP site plan and design details must be maintained as permeable pavement and may not be changed without written approval from the City of Renton. Permeable pavements must be inspected after one major storm each year to make sure it is workingproperly. Prolonged ponding or standing water on the pavement surface is a sign that the system isdefective and may need to be replaced. If this occurs, contact the pavement installer or the City of Renton for further instructions. A typical permeable pavement system has a life expectancy of approximately 25-years. To help extend the useful life of the system, the surface of the permeable pavement should be kept clean andfree of leaves, debris, and sediment through regular sweeping or vacuum sweeping. The owner is responsiblefor the repair of all ruts, deformation, and/or broken paving units.

report for the design of the foundations for the new addition to the existing Seattle Pipe Trades building. The existing building, which is supported on spread footings, was constructed on fill overlying floodplain deposits consisting of loose sand and soft to medium stiff silt. To provide a consistent level of performance with the existing structure, the new addition should also be supported on spread footings designed for an allowable bearing capacity of 2.5 ksf. The silts underlying the site are generally not susceptible to liquefaction, but some minor settlement may occur as a result of earthquake ground shaking. The near surface silts underlying the site may be used for stormwater infiltration as based on an estimated infiltration rate of 0.3 inches per hour. Sincerely, W. Paul Grant, P.E.

(PanGEO) completed a geotechnical engineering study to provide foundation design parameters for the new addition of the existing Seattle Pipe Trades building in Renton which is located at 595 Monster Road (see Figure 1). The study included evaluating the subsurface conditions at the site and providing recommendations for the foundation design of the new addition. The following summarizes our findings and conclusions. 1.1 SITE AND PROJECT DESCRIPTION The new two story addition will be located on the southeast side of the existing structure where the ground surface is relatively level at about elevation 25 feet. The new addition will encompass existing landscape and paved parking areas. The existing paved parking will be removed and reconstructed to the southeast. On-site stormwater infiltration will be incorporated into the new construction. 1.2 SCOPE OF WORK AND AUTHORIZATION Our work was accomplished in accordance with our proposal letter dated April 14, 2015, which was authorized by Mr. Scott Rice with Collins Woerman May 8th. Our work scope included reviewing existing geotechnical data for the site and nearby locations and advancing two borings adjacent to the existing building to explore subsurface conditions and provide the basis from which we developed design recommendations for the proposed expansion. 2.0 SITE RECONNAISSANCE On June 2, 2015, we conducted a site reconnaissance to mark locations of the proposed borings and observe any potential indication of differential settlement of the existing paved parking areas and the building. As a result of our reconnaissance, we did not observe any indication of significant settlement of the building. However, we did observe settlement and cracking of the pavements in the parking lots suggesting that the fill beneath the pavement has settled. 15-140 595 Monster Rd.doc PanGEO, Inc. 2 3.0 SUBSURFACE CONDITIONS 3.1 SOILS Subsurface conditions at the site were inferred from the results of two new borings that were drilled at the locations shown on Figure 2. Both borings were drilled to depths of 25 to 26 feet below the existing ground surface using hollow stem auger drilling equipment. Soil samples were taken in the borings at 2.5 foot intervals in the upper 10 feet of the borings and at 5 foot intervals thereafter. All sampling was conducted using the Standard Penetration Test (SPT) procedures. Summary logs of the borings are presented in Appendix A. Based upon the materials encountered in the borings, the site is underlain by recent fill overlying flood plain deposits, which overlie sandstone of the Tukwila Formation. The following describes the soils encountered in the explorations: Recent Fill – Both borings, which were located in the parking lot, encountered 2.5 inches of asphalt overlying loose to medium dense, silty, fine sand (Fill) which extended to depths of 3 to 4 feet. Floodplain Deposits – Underlying the fill, both borings encountered floodplain deposits consisting of approximately 5 to 7 feet of loose silty fine sand overlying about 10 feet of soft to medium stiff silt and clay. Bedrock – Bedrock consisting of weak sandstone of the Tukwila Formation was encountered at a depth of about 20 feet in Boring B-1. While not encountering bedrock, Boring B-2 encountered a medium dense sand below a depth of 23 feet, which may be alluvium overlying the bedrock. 3.2 GROUNDWATER Groundwater was inferred at a depth about 14 to 15 feet based on the appearance of the samples retrieved from the borings. 4.0 CONCLUSIONS AND RECOMMENDATIONS We recommend supporting the new addition on conventional spread and continuous footings, similar to the foundations supporting the existing building, to maintain a consistent level of support to the building and thereby avoid stress concentrations that might otherwise occur with the use of a mixed foundation system supporting different building sections. With loose fill underlying the footprint of the new addition, we recommend over excavating 2 feet of subgrade beneath the new footings and replacing the soil with structural fill compacted with a Ho-Pac to a dense and unyielding condition. Detailed design recommendations are presented below. 15-140 595 Monster Rd.doc PanGEO, Inc. 3 4.1 SEISMIC DESIGN PARAMETERS The following seismic design parameters are consistent with ASCE/SEI 41-13 which requires analyses for two Basic Safety Earthquakes (BSE’s) corresponding to a 10% probability of exceedance in 50 years (BSE-1) and a 2% probability of exceedance in 50 years (BSE-2). Furthermore, the BSE-1 earthquake motions may be limited to not exceed two-thirds of the motions from the BSE-2 event. The following parameters, which are consistent with the 2008 USGS seismic hazard maps, are recommended for the seismic design of the building improvements at the site with the following coordinates: 47.614°N, 122.328°W 4.2 LIQUEFACTION The floodplain deposits below the water table are typically low strength clayey silts to organic silts that may experience some reduction in strength as a result of strong earthquake ground shaking. However, because these soils are overlain by nearly 15 feet of soil that would not experience liquefaction; any slight reduction of strength in the underlying soft silt is not expected to affect the performance of the existing building or the new addition. 4.3 SPREAD FOOTING FOUNDATIONS In our opinion, conventional spread and strip footings may be used to support the new addition. All footings should be founded a minimum distance of 18 inches below the finished grade and should have a minimum width of 18 inches. To reduce footing settlement, we recommend that all footings be over excavated to a depth of 2 feet and the excavated material replaced with a compacted structural fill, which will also serve as a working platform for the footing construction. We recommend use of a Ho-Pac to compact the over-excavated subgrade and the structural fill to a dense and unyielding condition. All footing excavations should observed by PanGEO to confirm that the Event Site Class SS S1 Site Coefficients Spectral Response Parameters Control Periods (sec.)

We recommend that the footings be sized using a maximum allowable bearing pressure of 2.5 ksf which may be increased by 1/3 for transient conditions such as wind and seismic loadings. Total static settlements for the footings as constructed as described above are anticipated to be on the order of 1 inch. Most settlement will occur during construction as loads are applied. Total building settlements following a large earthquake are expected to be on the order of 1 to 2 inches. Lateral forces from wind or seismic loading may be resisted by the combination of passive earth pressures acting against the embedded portions of the foundations and by friction acting on the base of the foundations. Passive resistance values may be determined using an equivalent fluid weight of 360 pounds per cubic foot (pcf). This value includes a factor safety of at least 2 assuming that the properly compacted structural fill will be placed adjacent to the sides of the footings. A coefficient friction of 0.5 may be used to determine the frictional resistance at the base of the footings. This coefficient includes a factor safety of approximate 1.5. 4.4 STRUCTURAL FILL AND COMPACTION We recommend using all weather material such as City of Seattle Mineral Aggregate Type 17 (2003 City of Seattle Standard Specifications, 9-03.12(3)) or WSDOT Gravel Borrow (9-03.14(1)) for structural fill. The backfill should be moisture conditioned to within about 3 percent of optimum moisture content, placed in loose, horizontal lifts less than 8 inches in thickness, and systematically compacted to a dense and relatively unyielding condition and to at least 95 percent of the maximum dry density, as determined using test method ASTM D 1557. 4.5 FLOOR SLABS Slab on grade floors (i.e. floors that are not structurally supported) should be constructed over subgrade that has been compacted to a dense and unyielding condition. We recommend use of a modulus of subgrade reaction of 100 pci for the floor slab design. All floor slabs should be constructed on a minimum 4-inch thick capillary break consisting of free-draining, crushed rock or well-graded gravel compacted to a firm and unyielding condition. The capillary break material should have no more than 10 percent passing the No. 4 sieve and less than 5 percent by weight of the material passing the U.S. Standard No. 100 sieve. City of Seattle Type 22 material meets this gradation requirement. We also recommend that a 10-mil polyethylene vapor barrier be placed below the slab. 15-140 595 Monster Rd.doc PanGEO, Inc. 5 4.6 STORMWATER INFILTRATION Should pervious pavements be used for the new construction, there must be at least 12 inches of soil below the pavement that is suitable for treating the infiltrating water before the water reaches the groundwater table. The 2012 Ecology Manual specifies soils suitable for treatment have a long term infiltration rate of less than 3 inches per hour, a cation exchange capacity (CEC) greater than or equal to 5.0 meq/100g, and an organic content (OC) of greater than 1 percent. However, the 2012 LID Technical Guidance Manual for Puget Sound (WSU 2012) indicates that an organic content of 0.5% would be acceptable provided that the layer is at least 18” thick. If the above criteria are not meet, the upper 12 (or 18) inches of soil below the pavement section would need amendment with organics or fertilizer to fall below the maximum infiltration rate and above the minimum CEC and OC. Laboratory tests conducted on the site soils include grain size analyses for estimating long term infiltration rates and CEC and OC testing. The results of the laboratory testing are summarized below. Boring No. Sample Depth (Ft.) CEC (meq/100 g) OC (%) D10 (mm) D60 (mm) D90 (mm) Est. Long Term (Design) Infiltration Rate (in/hr.) B-1 7.5 20.4 15.6 ~0.02 0.43 6 0.3 B-2 7.5 2.01 6.26 ~0.02 0.30 0.4 0.3 Estimated long term infiltration rates for the site soils of 0.3 inches per hour are based on the soil type as sandy loam to loamy sand in accordance with the 2005 Stormwater Manual.. 4.7 PAVEMENT We recommend that the pavement section in areas of automobile parking and drive lanes with light to moderate commercial vehicles consist of 3 inches of hot mix asphalt (HMA) overlying 6 inches Crushed Surfacing Base Course (CSBC) (WSDOT 9-03.09(3)) over subgrade that has been compacted to a dense and unyielding condition. All materials within the pavement section should be compacted to 95% of the materials maximum dry density, as determined using test method ASTM D 1557. 15-140 595 Monster Rd.doc PanGEO, Inc. 6 5.0 CONSTRUCTION CONSIDERATIONS 5.1 MATERIAL REUSE The native on-site soils with silt contents in excess of about 5% may be difficult to handle and compact during wet weather. If use of the existing soils is planned, any excavated soil should be stockpiled and protected with plastic sheeting to prevent softening from rainfall. 5.2 SURFACE DRAINAGE AND EROSION CONSIDERATIONS Surface runoff can be controlled during construction by careful grading practices. Typically, this includes the construction of shallow, upgrade perimeter ditches or low earthen berms to collect runoff and prevent water from entering excavations. Temporary erosion control may require the use of hay bales on the downhill side of the project to prevent water from leaving the site and potential storm water detention to trap sand and silt before the water is discharged to a suitable outlet. All collected water should be directed to a permanent discharge system such as a storm sewer. It should be noted that the site soils are prone to surficial erosion. Special care should be taken to avoid surface water on open cut excavations, and exposed slopes should be protected with visqueen. Temporary provisions may also be required such as the use of quarry spalls at the entrance to the construction site to reduce the possibility of the offsite transport of soil on the truck tires. Permanent control of surface water and roof runoff should be incorporated in the final grading design. All collected runoff should be directed into conduits that carry the water away from the pavement or structure and into storm drain systems or other appropriate outlets. Adequate surface gradients should be incorporated into the grading design such that surface runoff is directed away from structures. 5.3 WET WEATHER EARTHWORK General recommendations relative to earthwork performed in wet weather or in wet conditions are presented below:  Earthwork should be performed in small areas to minimize subgrade exposure to wet weather. Excavation or the removal of unsuitable soil should be followed promptly by the placement and compaction of clean structural fill. The size and type of construction equipment used may have to be limited to prevent soil disturbance.  During wet weather, the allowable fines content of the structural fill should be reduced to no more than 5 percent by weight based on the portion passing ¾- inch sieve. The fines should be non-plastic. 15-140 595 Monster Rd.doc PanGEO, Inc. 7  The ground surface within the construction area should be graded to promote run-off of surface water and to prevent the ponding of water.  Bales of straw and/or geotextile silt fences should be strategically located to control erosion and the movement of soil. Erosion control measures should be installed along all the property boundaries.  Excavation slopes and soils stockpiled on site should also be covered with plastic sheets. . 6.0 CONSTRUCTION SUPPORT SERVICES The recommendations presented in this report are based on the assumption that an adequate program of tests and observations will be made during construction to verify compliance with these recommendations. These tests and observations should include, by not necessarily be limited to, the following:  Review final project plans and specifications  Verify implementation of erosion control measures  Verify adequacy of subgrades beneath footings, floor slabs and pavements  Confirm the adequacy of compaction of structural backfill  Other consultation as may be required during construction Pending the completion of the final design drawings, we will provide you a proposal for construction monitoring services to address the above items. Geotechnical construction monitoring, by the geotechnical engineer of record, may be required by the City of Renton to obtain an occupancy permit for the building. We will provide the services necessary to assure you compliance with the Building Permit. 7.0 LIMITATIONS We have prepared this report for use by the consultant team for the design of the new addition.
