Our property is across the street from 14625 46th Ave South. It has recently come to our attention that a notice was listed to build "6 Lot Short Plat" at the 14625 46th Ave South location. We feel that "6 Lot Short Plat" is too much for that property and "3 Lot Short Plat" would be a better fit for our neighborhood. Our reasons are as follows: This would add more traffic in an area that has no sidewalks. It is a good walking neighborhood where many people walk for exercise. Also, there are a lot of children in the neighborhood that play and walk on the street as they go to the nearby schools. - Too many houses built on that property, will change the traditional characteristic of the neighborhood that has been maintained for many, many years. We are very fond of the many animals, trees and foliage surrounding the area. We ask that building "6 Lot Short Plats" be reconsidered to "3 Lot Short Plats" for the property at 14625 46th Ave South.

I am very concerned the effect of dividing this property into six properties will have on our small neighborhood and on it's parking, traffic, utilities, character, pedestrian traffic and sidewalks etc. We purchased our property in the summer of 2009. We bought our house in spite of the negative influences of Tukwila International boulevard with it's flophouse motels drug dealing and prostitution because we liked our small neighborhood which was an oasis against a dangerous environment. WE know and like many of our neighbors. Since then the City of Tukwila removed those motels and we have vastly improved area developing. The main threat to this improvement is over developing the population density of our neighborhoods. My street, 46th Ave South, has a white line in the asphalt to designate the "sidewalk" on the west side ,of the street with no parking on that side. It's used as a sidewalk by some but many people just walk in the street. All the mail boxes are on the east side making limited parking on that side also. On the north end of my street at 144th there are two schools Foster High School and Showalter Middle School and Tukwila Pool. At the South end of my street at 150th is Thorndyke Elementary School. Lots of children are using my street every day. Some of them may use the "sidewalk". It's difficult since oftentimes cars are illegally parked in the sidewalk due to the limited parking. If King Tuk subdivides their property to six small lots with six possibly mega homes this will have a very negative effect on street parking and the increased traffic will negatively effect the safety of pedestrians and the many children using the street. There are quite a few other oversize lots in the area and if they are allowed develop with such small lots it changes the character of the whole area. I would like to see King Tuk limited to three lots and have limits to the size and height of homes allowed. Furthermore, there are street improvements they need to make to lessen the traffic impacts. Speed bumps to slow traffic and adding real sidewalks. Is there an analysis of the impact on street utilities, water, gas, sewer, electricity, etc. And who pays? I would like them to be required to put in adequate and appropriate fencing and vegetative barriers between their properties and mine.

The comment period ended on January 1st. Come on guys! I don't really think that having the comment period occur over a two week period over Christmas and New Years gives people the opportunity consider the impacts and make appropriate commentary. I request that the comment period be extended two weeks so people have the time to comment if they want. I further suggest that future comment periods be extended by any Holliday so people can consider and comment. Let's be fair. If the IRS can extend deadlines due to hollidays perhaps Tukwila can too.

Date July transmitted: 18 , 2018 Response requested by: August 2, 2018 Staff coordinator: Lindsay Brown Date response received: REVIEWERS: Please specify how the attached plans conflict with your ADOPTED development regulations, including citations. Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60-day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.

Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60-day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.

Field observations were documented in the Soil Assessment Memorandum, dated October 14, 2017. The memo is attached in Appendix A. SECTION 2: CONDITIONS AND REQUIREMENTS Design Standards The 2016 King County Surface Water Manual sets forth the drainage requirements for this project. The project is subject to full drainage review. The nine (9) Core Requirements and five (5) Special Requirements of the SWM drainage requirements are detailed in this section. Table 3 provides a summary to the requirements. Table 3 - Jurisdictional Requirements Peak Run-off Control: Level 2 Water Quality: Basic Conveyance: 25-years Downstream Analysis: Level 1, �/a mile Core Requirement #1: Discharge Location at Natural Location Drainage Basin The property lies within the Duwamish River and Lower Green River — West drainage basin. The site is fairly level, with the general topography of the site sloping from south to northeast. Elevations on the site vary from a high point of 314 feet at the southwestern property corner to 310 feet at the northeastern property corner. Discharge at the Natural Location Existing drainage patterns and a topographic data available on City of Tukwila's stormwater inventory map indicate that the runoff from the site sheet flows east towards 46th Ave South where it enters the existing CB and flows north on 46th Ave South. In the developed condition, stormwater will be routed to the on -site detention facility prior to discharging to the storm drain system on 46th Ave South. The Concept Group Page 2 King Tuk Short Plat -Technical Information Report June 2018 Project Location Flow Direction Discharge Location Figure 2: Drainage Study Area Map Not -to -Scale Core Requirement #2: Offsite Analysis Level 1 Downstream Analysis A Level 1 downstream analysis was performed on June 6, 2018. During heavy rainfall events, overflow of stormwater sheet flows east and discharges into a CB located on 46th Ave South. Stormwater flows in a series of CB's and 12" storm drain closed pipe system along 46th Avenue South for approximately 950 FT. Stormwater then combines with the drainage from South 144`h Street and flows east in the 18" pipe system for along South 144th Street for another 1,250 FT, beyond a ''A mile from the site. Drainage System Description and Problem Descriptions A resource review was conducted to document existing and potential flooding and erosion problems. Based on this field inspection there appears to be no current significant erosion or capacity problems within a 'A mile downstream of the property. • Other Offsite Reports: Per the stormwater map on King County's iMap, there are no significant existing drainage or flooding problems within a'A mile downstream of the project. • Wetlands Inventory: The project site is not located in or near a mapped wetland per the City of Tukwila's Sensitive areas map. Refer to Figure 3 below. • Hazard Area and Landslide Area Maps: The project site is not located in or near a mapped hazard or landslide per the City of Tukwila's Sensitive areas map. Refer to Figure 3 below. The Concept Group Page 3 King Tuk Short Plat -Technical Information Report June 2018 1 Figure 3: Sensitive Area Map Not -to -Scale Mitigation of Existing or Potential Problems No existing or potential flooding, capacity, or erosion problems were observed during the site visit requiring mitigation. Based on this field inspection and research of King County records; there are no apparent erosion or capacity problems within '/a mile downstream of this project. Core Requirement #3: Flow Control The property is located within the Level 2 Flow Control. Western Washington Hydrology Model The Western Washington Hydrology Model (WWHM) was used to analyze the pre and post developed runoff rates. Table 4 outlines the assumed existing conditions. Table 5 outlines the assumed developed conditions.

An Erosion and Sedimentation Control plan has been prepared to assist the contractor in complying with these requirements and designed to prevent sediment -laden run-off from leaving the site during construction. Refer to Appendix C for Erosion Control plans and details. The erosion potential of the site is influenced by four major factors: soil characteristics, vegetative cover, topography, and climate. Erosion/ sedimentation control is achieved The Concept Group Page 5 King Tuk Short Plat -Technical Information Report June 2018 by a combination of structural measures, cover measures, and construction practices that are tailored to fit the specific site. Construction Sequence and Procedure Prior to the start of any grading activity upon the site, all erosion control measures, including installation of a stabilized construction entrance, shall be installed in accordance with the construction documents. The best construction practice will be employed to properly clear and grade the site and to schedule construction activities. The planned construction sequence for the construction of the site is as follows: 1. Flag or fence clearing limits. 2. Install catch basin protection if required. 3. Grade and install construction entrance(s). 4. Install perimeter protection (silt fence, brush barrier, etc.). 5. Construct sediment ponds and traps. 6. Grade and stabilize construction roads. 7. Construct surface water controls (interceptor dikes, pipe slope drains, etc.) simultaneously with clearing and grading for project development. 8. Maintain erosion control measures in accordance with City of Tukwila and King County standards and manufacturer's recommendations. 9. Relocate erosion control measures or install new measures so that as site conditions change the erosion and sediment control is always in accordance with the King County Erosion and Sediment Control Standards. 10.Cover all areas that will be unworked for more than seven days during the dry season or two days during the wet season with straw, wood fiber mulch, compost, plastic sheeting or equivalent. 11.Stabilize all areas that reach final grade within seven days. 12.Seed or sod any areas to remain unworked for more than 30 days. 13. Upon completion of the project, all disturbed areas must be stabilized and BMPs removed if appropriate. Trapping Sediment Structural control measures will be used to reduce erosion and retain sediment on the construction site. The control measures will be selected to fit specific site and seasonal conditions. The following items will be used to control erosion and sedimentation processes: • Temporary gravel construction entrance • Filter fabric fences (Silt fences) • Ground cover measures such as straw cover and/or hydroseeding • Inlet protection Vehicle tracking of mud off -site shall be avoided. Installation of a gravel construction entrance will be installed at a location to enter the site. The entrances are a minimum requirement and may be supplemented if tracking of mud onto public streets becomes excessive. The Concept Group Page 6 King Tuk Short Plat -Technical Information Report June 2018 Core Requirement #6: Maintenance and Operations Maintenance and operations of all drainage facilities located within the private residential properties is the responsibility of the applicant or property owner in accordance with the requirements as attached in Appendix D. Proper maintenance is important for adequate functioning of the stormwater facilities. If it is unclear whether a problem exists, contact a Professional Engineer. Core Requirement #7: Financial Guarantees and Liability Proposed BMP's are privately owned and maintained. The project does not require financial guarantees. Maintenance and operation of all drainage facilities and BMP's are the sole responsibility of the property owner. Core Requirement #8: Water Quality This project is required to provide Water Quality treatment as defined by Core Requirement #8 because it proposes 13,590 square feet in pollution -generating impervious surface (PGIS). PGIS is defined as "an impervious surface considered to be a significant source of pollutants in surface and storm water runoff. Such surfaces include those subject to vehicular use or storage of erodible or leachable materials, wastes, or chemicals, and which receive direct rainfall or the run-on or blow-in of rainfall." Non- metal rooftops are not considered PGIS; therefore, are not included in the PGIS area calculations. Water quality will be maintained through the construction of a Contech StormFilter Catch Basin to be located downstream of the detention BMP. The proposed treatment has been designed to treat the full 2-year release rate from the detention tank. Refer to Appendix B for the detailed calculations. Core Requirement #9: Flow Control BMP The project utilizes Better Site Design by generally matching existing grades where feasible. Existing trees and other vegetation around the site perimeter will be preserved where possible to help minimize disturbance to the hydrologic cycle. Native soils in all disturbed pervious areas will be amended with compost. Soil Management Plan Within the limits of site disturbance, duff and topsoil will be retained in an undisturbed state and stockpiled for later use to stabilize and amend soils throughout the Site. Postconstruction soil amendment will meet the requirements of the 2016 KCSWDM Appendix C, Section C.2.13. BMP Feasibility and Applicability Discussion Section 1.2.9.2, Small Lot BMP is required for the individual lots for this project. • Full dispersion, per Appendix C, Section C.2.1, of runoff from impervious surfaces is not feasible due to insufficient area on the site for dispersion flow paths. The site does not contain native vegetation; therefore, a native vegetative flow path of 100 ft is not feasible within the project limit. The Concept Group Page 7 King Tuk Short Plat -Technical Information Report June 2018 • Full infiltration, per Appendix C, Section C.2.2, is not feasible due to the presence of and underlying layer of clay at the site. Infiltration tests were conducted; however, the water level in the test pit remained constant, yielding an infiltration rate of 0.0 inches/hour. Refer to the soil memorandum submitted under a separate cover. • Limited Infiltration/Rain Gardens/Bioretention/Permeable Pavement. Infiltration BMP's are not feasible for this site. Refer to note in full infiltration discussion. • Basic Dispersion, per Appendix C, Section C.2.4 is not because a vegetative flow path of 25 ft cannot be provided due to site constraints. The project proposes a direct connection to the on -site detention tank to mitigate onsite stormwater from the development. Special Requirement #1: Other Adopted Requirements Based on available data at the time this report was prepared, there are no one Special Adopted Requirements for this project. Special Requirement #2: Flood Hazard Area Delineation Based on FEMA Flood Map # FM53033C0957F and King County iMap Districts and Development Conditions report, the project area is located in Zone X, a 500-year flood plain Special Requirement #3: Flood Protection Facilities This project is exempt from Special Requirement #3 because it does not rely on an existing flood protection facility or propose to modify or construct a new flood protection facility. Special Requirement #4: Source Control This project is a residential development. It is not a commercial, industrial, or large multifamily site development; therefore, it is exempt from Special Requirement #4. Special Requirement #5: Oil Control This project not defined as a high -use site per section 1.3.4 of the 2016 KCSWM; therefore, it is exempt from Special Requirement #5 The Concept Group Page 8 King Tuk -Technical Information Report Appendix A Soils Information The Concept Group Appendices 4g11;;Nwern the CONCEPT group MEMORANDUM 4701 SW Admiral Way, Ste 353 • Seattle, WA 98116 • T 206.446.1291 • www.ConceptBusinessGroup.com Date: October 14, 2017 To: City of Tukwila From: Anna Nguyen, P.E. Subject: Soil Assessment Project Address: 14625 46th Avenue South DocuSigned by: D9363A2AA4134C9 Geologic Setting The Geologic Map of the King County, by Derek B. Booth et al, published in 2007, was referenced for the geologic and soil conditions of the project site. According to this publication, the surficial soil unit at the project site and its immediate vicinity is mapped as glacial till (Qvt). The Geologic Map of Seattle Not -to -Scale A NEW DIMENSION OF DESIGN PERCEPTION 14625 46th Avenue South Page 2 of 2 Soils Investigation Soils on this property were investigated under my supervision on October 14, 2107. Three (3) test pits were excavated in the vicinity of the proposed stormwater BMP location. In accordance with Section C.2.2 of the 2016 King County Surface Water Design Manual, soil logs are required to be excavated to a minimum depth of 5 feet. Soil log explorations were excavated to a depth of 5.0 feet at this site. Groundwater The soil sample was collected during the dry -season. No groundwater seepage was observed. Hydraulic Restrictive Layer The test pits were excavated to a total depth of 4.0 ft. There was a hardpan layer of clay at the depth of 2.5 ft. Infiltration Test Infiltration testing was conducted in the 5.0 ft deep test pit; however, due to the presence of the till soil and clay, the water level in the test pit remained constant after one hour of testing. We conclude that soils are NOT conducive to infiltration BMP's. Limitations The conclusions and recommendations contained in this report are based on site conditions as they existed at the time of our exploration and assume that the soil and groundwater conditions encountered in the test pits are representative of subsurface conditions on the site. If the subsurface conditions encountered during construction are significantly different from those observed in our explorations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Unanticipated soil conditions are commonly encountered on construction sites and cannot be fully anticipated by merely taking soil samples in test pits. Subsurface conditions can also vary between exploration locations. Such unexpected conditions frequently require making additional expenditures to attain a properly constructed project. This report has been prepared for the exclusive use of the property owner and its representatives for specific application to this project and site. Our recommendations and conclusions are based on observed site materials and engineering analyses. Our conclusions and recommendations are professional opinions derived in accordance with current standards of practice within the scope of our services and within budget and time constraints. No warranty is expressed or implied. The scope of our services does not include services related to construction safety precautions, and our recommendations are not intended to direct the contractor's methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in stormwater design.

C=l► NTECH ENGINEERED SOLUTIONS Size and Cost Estimate Prepared by Mike Gillette on February 6, 2018 14625 26th Ave S — Stormwater Treatment System Tukwila, WA Information provided: • Presiding agency = City of Tukwila Structure ID Water Quality Flow Rate (cfs) 0.029 Peak Flow Rate (cfs) 0.113 Number of cartridges 2 Cartridge flow rate (gpm) 7.5 Media type ZPG Structure size 48" Manhole Approximate Price $16,500 Assumptions: • Media = ZPG cartridges providing basic level treatment • System depth is 6' from rim to outlet • Drop required from inlet to outlet = 2.3' minimum Size and cost estimates: The StormFilter is a flow -based system, and is therefore sized by calculating the peak water quality flow rate associated with the design storm. The water quality flow rate was calculated by the consulting engineer using WWHM and was provided to Contech Engineered Solutions LLC for the purposes of developing this estimate. The StormFilter for this site was sized based on the above water quality flow rate. To accommodate this flow rate, Contech Engineered Solutions recommends using (2) — 18" cartridges with ZPG media in a 48" manhole. The estimated cost of this system is shown in the above table; this estimate includes a complete system delivered to the job site. The final system cost will depend on the actual depth of the units and whether extras like doors rather than castings are specified. The contractor is responsible for setting the StormFilter manhole and all external plumbing. Typically the StormFilter manhole has an internal bypass capacity of 1.8 cfs. Since the peak discharge is not expected to exceed this rate, a high -flow bypass upstream of the StormFilter system is not required. ©2012 Contech Engineered Solutions LLC 11835 NE Glenn Widing Dr., Portland OR 97220 www.conteches.com Toll -free: 800.548.4667 Fax: 800.561.1271 Page 1 of 1 TS-P027 C AITECH ENGINEERED SOLUTIONS Determining Number of Cartridges for Flow Based Systems CONTECH Stormwater Solutions Inc.

The scope of our work included reviewing existing geologic and geotechnical data in the site vicinity, conducing a site reconnaissance, excavating five test pits, and developing geotechnical recommendations for the design of the proposed project. Based on the results of the field exploration, the subsurface soils at the site generally consisted of a layer of topsoil/fill overlying dense to very dense glacial till. Groundwater seepage was not observed within the test pit depths during the field exploration. In our opinion, the proposed development is feasible from a geotechnical standpoint. Based on the soil conditions at the site, in our opinion, the proposed new single-family buildings may be supported by conventional footings. However, over -excavation of fill or loose soils will be needed below the design footings. It is our opinion that temporary excavations may be accomplished with unsupported, sloped open cuts. Cascade GeotechNW appreciates the opportunity to be of service to you for this project. Please contact us at if you have any questions or we can be of further assistance.

The purpose of our work was to evaluate the subsurface conditions at the site and provide geotechnical recommendations regarding earthwork, foundation design, concrete slabs, and retaining walls for the proposed development. Authorization to conduct the geotechnical engineering study was provided by Mr. Dao on February 1, 2018. 2.0 SITE AND PROJECT DESCRIPTION The subject site is an approximately 1.09-acre lot located at 14625 — 46th Avenue South in the City of Tukwila, Washington (see Figure 1, Vicinity Map). The property is approximately rectangular in shape, and is bordered to the east by 46th Avenue South, and to the other three sides by existing single-family residences. An existing one-story house and a barn currently occupies the site. The majority of the site is generally flat. However, based on review of the topographic survey map and our observations, the western edge of the site slopes down from east to west with an average of about 7 percent. Based on the information provided to us, we understand that you plan to subdivide the property into six single-family parcels (see Figure 2). The existing structures will be removed for the new development. We also understand that you plan to construct a new single-family residence on each newly created parcel. Detailed design information for the proposed new residences is not available at the time this report was prepared. However, we envision that the proposed new houses will be three-story wood frame structures with a combination of crawl space and slab -on -grade floors. We anticipate that site grading will involve cuts and fill on the order of 3 to 4 feet for the foundation construction. The conclusions and recommendations outlined in this report are based on our understanding of the proposed development, which is in turn based on the project information provided. If the above project description is incorrect, or the project information changes, we should be consulted to review the recommendations contained in this study and make modifications, if needed. 2018-001 14625 - 46h Avenue S Rpt Page 1 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 3.0 PROJECT SCOPE The purpose of our geotechnical engineering study for the proposed development is to characterize subsurface conditions at the project site. The subsurface information obtained was used to develop geotechnical engineering recommendations pertinent to the design and construction of the subject project. The scope of our work for this project included the following tasks and work efforts: 1. Conducted a site reconnaissance to observe the existing site conditions, and to identify site conditions that may impact the proposed development from a geotechnical standpoint. 2. Reviewed readily available geologic and geotechnical data for the project area to supplement our subsurface exploration program at the subject site. 3. Excavated five (5) test pits to evaluate the general subsurface conditions at the site and to evaluate the potential geotechnical constrains for the proposed development. The test pits were excavated using a backhoe to about 5 and 7 feet below the existing grade, depending on the actual subsurface conditions encountered at each location. 4. Performed engineering analyses to develop engineering recommendations pertinent to the proposed development. 5. Preparation of this geotechnical report summarizing our work on the project and presenting our findings and preliminary geotechnical recommendations. Detailed descriptions and logs of the field exploration are presented in Appendix A of this report. It should be noted that our scope of work does not include an evaluation of chemical properties of soil and groundwater. Our scope also does not include evaluation of stormwater infiltration. 2018-001 14625 - 46h Avenue S Rpt Page 2 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 4.0 SITE GEOLOGY AND SUBSURFACE CONDITIONS 4.1 SITE GEOLOGY According to the geology maps of the area (The Geologic Map of King County, Washington: scale 1:100,000, Booth, D. B., Troost, K. A., and Wisher, A. P., 2007), the project area is underlain by Vashon Till (Map Unit Qvt). Vashon Till generally consists of an unsorted deposit (diamict) of clay, silt, sand and gravel that has been glacially transported and deposited. Vashon Till is dense to very dense, however the upper surface is typically weathered to a loose to medium dense consistency. 4.2 SUBSURFACE CONDITIONS We excavated five (5) test pits to explore the subsurface conditions at the site. The soils observed in the test pits consisted of a layer of fill/topsoil overlying glacial till deposit. The subsurface exploration is generally consistent with the mapped geology at the site. The following is a brief description of the soils encountered in the test pits excavated at the site. Please refer to the summary test pit logs in Appendix A for additional details. Unit 1 - Topsoil/Fill: Topsoil/fill was encountered in all five test pits to about 1 to 5 feet below the surface. The topsoil/fill generally consisted of loose, moist to very moist, silty sand to sandy silt with trace to some gravel and roots. Unit 2 — Glacial Till Deposit: Below fill/topsoil, all test pits encountered silty sand with gravel with occasional cobbles and boulders that extended to the bottom of the borings at about 5 to 7 feet below the surface. We interpret this unit as mapped Vashon Glacial Till Deposit. The glacial till encountered was slightly cemented, and dense to very dense in density. Groundwater seepage was not observed within the excavations depths during our field exploration. It should be noted that perched groundwater and seepage are frequently present atop of the dense till and within the permeable zones of the glacial till in the wet season. It should also be noted that groundwater elevations may vary depending on the season, local subsurface conditions, and other factors. Groundwater levels and seepage rates are normally highest during the winter and early spring. 2018-001 14625 - 46h Avenue S Rpt Page 3 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 5.0 GEOLOGY HAZARDS ASSESSMENT 5.1 LANDSLIDE HAZARDS AND STEEP SLOPES Based on the site topography, the soil conditions, and the City of Tukwila Sensitive Areas Map, it is our opinion the site is not considered as a Potential Landslide Hazard area. A site reconnaissance of the subject property was conducted on February 10, 2018. During our site reconnaissance, we did not observe obvious evidence of past slope instability or ground movement at the. Based on our field observations, the relatively gentle topography at the site and vicinity, the relatively low slope height, and the results of the subsurface exploration, in our opinion, the subject site is globally stable in its current configuration. It is also our opinion that the proposed short plat and the single-family residence as currently planned is feasible from a geotechnical engineering standpoint and will not adversely affect the overall stability of the site or adjacent properties, provided the recommendations herein are followed and standard practice is implemented during construction. 5.2 EROSION HAZARDS Based on the soils encountered in the test pits and site topography, the near -surface site soils will have low to moderate erosion potential. In our opinion, erosion potential at the site, if any, can be effectively mitigated with the best management practice during construction and with properly designed and implemented landscaping for permanent erosion control. During construction, the temporary erosion hazard can be effectively managed with an appropriate erosion and sediment control plan, including but not limited to installing silt fence at the construction perimeter, limiting removal of vegetation to the construction area, placing rocks or hay bales at the disturbed/traffic areas and on the downhill side of the project, covering stockpile soil or cut slopes with plastic sheets, constructing a temporary drainage pond to control surface runoff and sediment trap, placing quarry spalls at the construction entrance, etc. Permanent erosion control measures should include establishing vegetation, landscape plants, and hardscape established at the end of project, and reducing surface runoff to the minimum extent possible. It is our opinion that the potential for future erosion at the site is low, provided that the earthwork and permanent erosion control recommendations are properly implemented. 2018-001 14625 - 46h Avenue S Rpt Page 4 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 5.3 SEISMIC HAZARDS The City of Tukwila Municipal Code defines seismic hazard areas as those areas subject to risk of damage as a result of earthquake -induced ground shaking, slope failure, and soil liquefaction or surface faulting. Based on the dense nature of the near - surface soil and lack of defined static groundwater table at the site, it is our opinion that the potential for soil liquefaction during an IBC -code level earthquake at the site is considered low. It is also our opinion that the potential for seismic -induced landslidng is low at the site due to the dense soil conditions and relatively level surface. Therefore, special design considerations associated with soil liquefaction and seismic - induced landsliding are not necessary for this project. 6.0 DISCUSSION AND RECOMMENDATIONS 6.1 GENERAL Based on the subsurface conditions at the site, it is our opinion that the proposed residential development is feasible from a geotechnical standpoint. Our recommendations for the seismic design, earthwork, foundations, concrete slabs, and retaining wall are presented in the following sections. 6.2 SEISMIC DESIGN PARAMETERS The Table 1 below provides seismic design parameters for the site that are in conformance with the 2015 edition of the International Building Code (IBC), which specifies a design earthquake having a 2% probability of occurrence in 50 years (return interval of 2,475 years), and the 2008 USGS seismic hazard maps.

Site preparation should begin with the removal of surface vegetation within the proposed improvement areas (i.e. building pads and driveway areas), and excavating to the design subgrade. Based on our site exploration, we anticipate stripping depths of about 18 inches at the site. Organic rich topsoil, fill, and other deleterious materials, should also be removed as part of stripping operation. Based on the test pit excavations, organic rich topsoil/fill will likely extend to about 2 feet deep in the eastern portion of the site and could be as deep as 5 feet deep in the western portion of the site. All stripped surface materials should be properly disposed off -site or be "wasted" on site in non-structural landscaping areas. Following site clearing and excavations, the adequacy of the subgrade where structural fill, foundations, slabs, or pavements are to be placed should be verified by a representative of Cascade GeotechNW. The exposed subgrade should be proof -rolled to check the soft/loose soils. The soft/loose soils detected during proof -rolling operation and cannot be re -compacted to a dense and unyielding condition should be over -excavated and backfilled with compacted structural fill or CDF/lean-mix concrete. 6.3.2 Temporary Excavations In general, we anticipate site excavations to encounter topsoil/fill up to 5 feet over dense to very dense silty sand with gravel and cobbles (Glacial Till). It should be noted that the glacial till at the site is cemented and very dense in density, and excavations into the till will be slow and will require heavy excavation equipment, such as PC 200 or larger excavators. Use of hoerams or other methods may also be required in localized areas for denser till formation. All temporary excavations should be performed in accordance with Part N of WAC (Washington Administrative Code) 296-155. The contractor is responsible for maintaining safe excavation slopes and/or shoring. Excavations more than a total of 4 feet deep should be properly shored or sloped. For planning purposes, it is our opinion that temporary excavations may be sloped as steep as 1H:1V in fill and weathered till and H:1 V in the very dense till. 2018-001 14625 - 46h Avenue S Rpt Page 6 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 The temporary excavations and cut slopes should be re-evaluated by a qualified geotechnical engineer in the field during construction based on actual observed soil conditions, and may need to be modified in the wet reasons. The cut slopes should be covered with plastic sheets in the raining season. We also recommend that heavy construction equipment, building materials, excavated soil, and vehicular traffic should not be allowed within a distance equal to 1/3 the slope height from the top of any excavation. 6.3.3 Material Reuse and Structural Fill Materials In the context of this report, structural fill is defined as compacted fill placed under footings, concrete stairs and landings, roadway, and slabs, or other load -bearing areas. In our opinion, the on -site soils are not suitable as structural fill. Structural fill, if needed, should consist of imported, well -grade, granular material, such as WSDOT CSBC (WSDOT 9-03.9(3)) or Gravel Borrow (WSDOT 9-03.14(1)) or approved equivalent. The on -site soils may be used as general fill in the non-structural and landscaping areas. If use of the on -site soil is planned, the excavated soil should be stockpiled and protected with plastic sheeting to prevent softening from rainfall in the wet season. 6.3.4 Structural Fill Placement and Compaction Requirements Structural fills should be placed in thin horizontal lifts not exceeding 10 inches in loose thickness, moisture conditioned to within about 3 percent of optimum moisture content, and systematically compacted to meet the following minimum relative densities based on the maximal dry density as determined using test method ASTM D 1557. Table 2 — Structural Fill Compaction Requirements Application Percentage Beneath conventional strip & column footings, patios, porches, and slab -on -grade floors 95% Beneath roadways, driveways, pavement areas, sidewalks and backfill behind retaining & basement walls (required for backfill next to vertical drain mats). 95% for the top 24 inches and 90-95% below 24 inches 2018-001 14625 - 46h Avenue S Rpt Page 7 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 Observations, probing, and soil density tests should be performed during grading operations to assist the contractor in obtaining the required degree of compaction and the proper moisture content on each fill lift. Where compaction is less than required, additional compactive effort should be applied with adjustment of moisture content as necessary, to obtain the specified compaction. 6.3.5 Permanent Cut and Fill Slopes Permanent cut and fill slopes should be graded no steeper than 2H:1V. Erosion control measures such as erosion -control mats and/or vegetation should be applied to the permanent slopes as soon as feasible. 6.4 BUILDING FOUNDATIONS Based on the soil conditions at the site, it is our opinion that the proposed single-family buildings may be supported on conventional footings bearing on undisturbed, competent native soils (till) or compacted structural fills placed on native competent soils. An allowable bearing capacity of 2,500 pounds per square foot (psf) may be used for sizing the footing. The recommended allowable bearing pressure is for dead plus live loads. For allowable stress design, the recommended bearing pressure may be increased by one- third for transient loading, such as wind or seismic forces. Continuous and individual spread footings should have minimum widths of 18 and 24 inches, respectively. Exterior foundation elements should be placed at a minimum depth of 18 inches below final exterior grade. Interior spread foundations should be placed at a minimum depth of 12 inches below the top of slab. Based on the test pit excavations, the bearing soils are about 2 to 5 feet below the existing site grade. As such, we anticipate that over -excavation of footing subgrade soil will likely be needed in western portion of the site and other localized areas. The depth of over -excavation needed will depend on the design footing level relative to the existing grade. For planning purpose, approximately 1 to 3 feet of footing subgrade over - excavations should be planned, assuming the footings are embedded about 2 feet below the existing grade. The footings can bear directly on the native competent till soils or structural placed on the native till soil. If structural fill is used in the footing areas, the 2018-001 14625 - 46h Avenue S Rpt Page 8 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 over -excavation and structural fill width should extend at least one-half the over - excavation depth beyond the edge of footing. Foundation Performance — For the anticipated light structural loading, we estimate total settlements of footings bearing on competent native soils or compacted structural fills to be on the order of 1-inch with differential settlements of about '/2-inch. Lateral Resistance — Lateral forces on the structures may be resisted by friction at the base of the foundations and by passive pressure acting against the buried portion of the foundation. To compute passive earth resistance, we recommend using an equivalent fluid weight of 300 pcf. Unless covered by pavements or slabs, the passive resistance in the upper 12 inches of soil should be neglected. For a base friction, a factor of 0.35 may beused between concrete and soil. These values are based on the foundations being constructed neat against competent native soils or backfilled with structural fill as described in the structural fill section. The values include a safety factor of 1.5. Perimeter Footing Drain — Footing drains should be installed around the perimeter of the buildings, at or just below the invert of the footings. Under no circumstances should roof downspout drain lines be connected to the footing drain systems. Roof downspouts must be separately tightlined to appropriate discharge locations. Cleanouts should be installed at strategic locations to allow for periodic maintenance of the footing drain and downspout tightline systems. Footing Excavation and Subgrade Preparation — All footing subgrades should be carefully prepared. Any fill, loose/soft, or organic -rich subgrade soil should be removed from the footing excavations. The footing subgrade may need to be recompacted to a firm, unyielding condition using a jumping jack or other heavy compaction equipment, prior to form setting and rebar placement. If the on -site native soil is still loose and yielding after re -compaction, they should be over -excavated to expose the bearing soil. The over -excavation should be backfilled with compacted structural fill or lean -mix concrete. The over -excavation width should extend at least one-half the over -excavation depth beyond the edge of footing. The adequacy of footing subgrade should be verified by a representative of Cascade GeotechNW prior to placing forms or rebar. If such observations are not performed during construction, Cascade GeotechNW cannot be held responsible for the long-term foundation performance. 2018-001 14625 - 46h Avenue S Rpt Page 9 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 6.5 SLAB -ON -GRADE In our opinion, conventional slab -on -grade may be utilized for this project. The floor slabs should be supported on firm/dense native soil or compacted structural fill. If the slab subgrade soils are soft and cannot be compacted to a firm/dense condition, they should be removed to expose firm/dense, competent native soil and the resulting over - excavation should be backfilled with structural fill compacted to a dense condition. Interior concrete slab -on -grade floors should be underlain by a capillary break consisting of at least of 4 inches of pea gravel or compacted'/4-inch, clean crushed rock (less than 3 percent fines). The capillary break material should also 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. The capillary break should be placed on the subgrade that has been compacted to a dense and unyielding condition. A 10-mil polyethylene vapor barrier should also be placed directly below the slab. We also recommend that construction joints be incorporated into the floor slab to control cracking. Where concrete slabs will be subjected to vehicular traffic such as the garage, we recommend that a 6-inch layer of base course (WSDOT CSBC) compacted to a minimum of 95 percent relative compaction be provided below the slabs in -lieu of the 4-inch thick capillary layer. 6.6 RETAINING AND BASEMENT WALL DESIGN PARAMETERS Retaining and basement walls should be properly designed to resist the lateral earth pressures exerted by the soils behind the wall. Proper drainage provisions should also be provided behind the walls to intercept and remove groundwater that may be present behind the wall. Our geotechnical recommendations for the design and construction of the retaining/basement walls are presented below. 6.6.1 Lateral Earth Pressures Concrete cantilever walls should be designed for an equivalent fluid pressure of 35 pcf for level backfills behind the walls assuming the walls are free to rotate. If walls are to be restrained at the top from free movement, such as basement walls, equivalent fluid pressures of 45 pcf should be used for level backfills behind the walls. Walls with a 2018-001 14625 - 46h Avenue S Rpt Page 10 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 maximum 2H:1 V backslope should be designed for an active and at rest earth pressure of 45 and 55 pcf, respectively. Permanent walls should be designed for an additional uniform lateral pressure of 7H psf for seismic loading, where H corresponds to the buried depth of the wall. The recommended lateral pressures assume that the backfill behind the wall consists of a free draining and properly compacted fill with adequate drainage provisions. 6.6.2 Surcharge Surcharge loads, where present, should also be included in the design of retaining walls. We recommend that a lateral load coefficient of 0.35 be used to compute the lateral pressure on the wall face resulting from surcharge loads located within a horizontal distance of one-half wall height. 6.6.3 Lateral Resistance Lateral forces from seismic loading and unbalanced lateral earth pressures may be resisted by a 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 300 pcf. This value includes a factor of safety of 1.5, assuming the footing is poured against dense native sand, re -compacted on -site sandy soil or properly compacted structural fill adjacent to the sides of footing. A friction coefficient of 0.35 may be used to determine the frictional resistance at the base of the footings. The coefficient includes a factor safety of 1.5. 6.6.4 Wall Drainage Provisions for wall drainage should consist of a 4-inch diameter perforated drainpipe behind and at the base of the wall footings, embedded in 12 to 18 inches of clean crushed rock and pea gravel wrapped with a layer of filter fabric. Where applicable, in -lieu of conventional footing drains, weep holes (2" diameter of 10 feet on center) may be used for site retaining walls. A minimum 18-inch wide zone of free draining granular soils (i.e. pea gravel or washed rock) is recommended to be placed adjacent to the wall for the full height of the wall. Alternatively, a composite drainage material, such as Miradrain 2018-001 14625 - 46h Avenue S Rpt Page 11 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 6000, may be used in lieu of the clean crushed rock. The drainpipe at the base of the wall should be graded to direct water to a suitable outlet. 6.6.5 Wall Backfill Based on the field exploration, the on -site soil would not be suitable for wall backfill due to its high fines content. Where wall backfill is needed, we recommend using free draining granular soils, such as WSDOT Gravel Barrow or clean crushed gravel. In areas where the space is limited between the wall and the face of excavation, 5/8" clean crushed rock or pea gravel may be used as backfill without compaction. Wall 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. Within 5 feet of the wall, the backfill should be compacted with hand -operated equipment to at least 90 percent of the maximum dry density. 6.7 WET WEATHER CONSTRUCTION In our opinion, the proposed site construction may be accomplished during wet weather (such as in winter) without adversely affecting the site stability. However, earthwork construction performed during the drier summer months likely will be more economical. Winter construction will require the implementation of best management erosion and sedimentation control practices to reduce the chance of off -site sediment transport. Some of the site soils contain a high percentage of fines and are moisture sensitive. Any footing subgrade soils that become softened either by disturbance or rainfall should be removed and replaced with structural fill, CDF, or lean -mix concrete. General recommendations relative to earthwork performed in wet conditions are presented below: • Site stripping, excavation and subgrade preparation should be followed promptly by the placement and compaction of clean structural fill or CDF; • The size and type of construction equipment used may have to be limited to prevent soil disturbance; 2018-001 14625 - 46h Avenue S Rpt Page 12 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 • The ground surface within the construction area should be graded to promote run- off of surface water and to prevent the ponding of water; • Geotextile silt fences should be strategically located to control erosion and the movement of soil; • Structural fill should consist of less than 5% fines; and • Excavation slopes should be covered with plastic sheets. All permanent cut and fill slopes should be protected so that erosion will not occur. Vegetation should be established as soon after construction as possible to provide long- term erosion protection of the slopes. Prior to establishing vegetation, silt fences and straw bales staked along contours and slopes are recommended to reduce erosion. The slopes should be periodically monitored until vegetation has become fully established. 6.8 SURFACE DRAINAGE AND EROSION CONTROL 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 in conjunction with silt fences to collect runoff and prevent water from entering excavations or to prevent runoff from the construction area from leaving the immediate work site. 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 under control to a positive and permanent discharge system. Permanent control of surface water should be incorporated in the final grading design. Adequate surface gradients and drainage systems should be incorporated into the design such that surface runoff is directed away from structures. We suggest that the ground surface be sloped at a gradient of 3 percent for a distance of at least 10 feet feet away from the building, except in paved areas, which can be sloped at a gradient of 1 percent. Potential problems associated with erosion may also be reduced by establishing vegetation within disturbed areas immediately following grading operations. 2018-001 14625 - 46h Avenue S Rpt Page 13 Cascade GeotechNW Geotechnical Engineering Report Proposed Development: 14625 — 46th Avenue S, Tukwila, WA February 16, 2018 Roof downspouts should be tightlined to discharge into the storm -water collection system separately from any footing drain system. Cleanouts should be installed at strategic locations to allow for periodic maintenance of the downspout tightline system. 7.0 ADDITIONAL GEOTECHNICAL SERVICES Plans and specifications should be forwarded to Cascade GeotechNW for review and written comments.

Cascade GeotechNW Proposed Development 14625. 16h Avenue S Tukwila, Washington Pr jcc: SITE AND EXPLORATIONS PLAN n No. zalrool z APPENDIX A - FILED EXPLORATION The subsurface conditions at the site were explored by excavating five (5) test pits to depths of 5 and 7 feet below the existing ground surface on February 10, 2018. The approximate locations of the test pits are shown on the Site Exploration Plan, Figure 2. The test pits were excavated with a backhoe owned and operated by G & R Excavating of Maple Valley, Washington. An engineer from Cascade GeotechNW was present during the field exploration to observe the test pit excavations, obtain representative samples, and to describe and document the soils encountered in the explorations. The materials encountered in the test pits were classified by visual and textural examination in the field by our engineer, who monitored the test pit excavations on a near -continuous basis in general accordance with ASTM Standard Practice D-2488, Description and Identification of Soils. The relative in -situ density of cohesionless soils, or the relative consistency of fine-grained soils was estimated from the excavating action of the back -hoe, and the stability of the test pit sidewalls. Where soil contacts were gradual or undulating, the average depth of the contact was recorded in the logs. After each test pit was logged, the excavation was backfilled with the excavated soils and the surface was tamped and re- graded smooth. Summary test pit logs are included in Figures A-1 through A-5 of Appendix A of this report. The key to the symbols and notations is shown on Figures A- 6andA-7.
