The City SEPA Responsible Official has previously determined that this application does not require a SEPA threshold determination because it is categorically exempt. This letter serves as the Notice of Decision per TMC 18.104.170. Based on the latest project submittal, preliminary approval is granted subject to the conditions stated below. The conditions imposed are to ensure the short plat is consistent with the Criteria for Preliminary Approval listed at TMC 17.12.020 C in the Tukwila Subdivision Code. Preliminary Approval Conditions 1) Revise the Short Plat Survey Map as follows: a) Add file number L18-0046 in the space provided at the upper left-hand corner on both sheets of the survey. b) Include the printed names of the owners on Sheet 1 of 2, in the area where their notarized signature will be made on the final short plat document. c) Add the existing parcel number to the area titled LEGAL DESCRIPTION (OLD) on Sheet 1 of 2. d) At the bottom of the survey sheets, both sheets are labeled "1 of 2". Revise the label on sheet 2 to say "2 of 2". e) The current address of 14213 34th Ave. S. will be retired from service. Label the assigned addresses on each lot as follows on sheet 2 of 2: Lot 1— 14205 34th Ave. S. Lot 2 — 14211 34th Ave. S.

OFFSITE ANALYSIS (Level 1 Downstream Analysis) Task 1: Study Area Definition and Maps The study area covered was the project site and upstream and downstream drainage areas near the development property. Task 2: Resource Review The project site is located within the Duwamish River Drainage Basin. Additionally, the site is not located in a critical drainage area. Research of available data shows no seismic hazard, landslide hazards, erosion hazards, or wetlands located on site. The soils on the site have been classified as Vashon Aged Glacial Till, see Geotech report. Task 3: Field Inspection Please refer to Figure 4 - Aerial Photograph and Figure 5 - Existing Site Conditions below to aid in the following description. 11 Figure 4 - Aerial Photograph 12 Figure 5 - Existing Site Conditions `14143 Existing Conditions The 24,750 sf project site has an existing house (soon to be demoed) and other than that is currently vacant. The site is covered with dense underbrush, deciduous trees, and evergreen trees along its frontage and property lines. The central portion of the property has been cleared. There is an existing gravel access drive which opens to an existing cleared area on the northern portion of the property. From the site visit, it appears the property was cleared in the last year and laid with gravel. The site topography ranges from 0 to 15% across the property towards the eastern portion of the site. It appears that the city has paved the frontage road, 34th Ave S recently which includes stormwater conveyance improvements. 13 Existing Access Drive Frontage of property looking South 14 Catch Basin on Frontage of Property The soil is classified as a Vashon Aged Glacial Till (see Geotech Report), 0 to 15 percent slopes by the Mizigi Group, Inc. The site is bordered on the north and south by single family homes and multi- family complexes as is typical of an urban residential neighborhood. There are no signs of ponding, flooding, or erosion problems on site or downstream of the site. Tributary Upstream Drainage The project site sits above the surrounding properties and therefore has no upstream drainage basin. Task 4: Downstream Drainage System Description and Existing and Potential Problems Based on research, and site visits there are no signs of drainage or erosion problems. The site will be mitigated through perforated pipe connections and will not contribute significant additional drainage to the city stormwater system. Drainage leaving the project site does so through sheet flow into a catch basin along the project frontage on 34th Ave S. It runs north, and then east through private property, reaching 35th Ave S and heading north through a series of SD pipes. It reaches the 0.25 mile mark just shy of the 35th Ave S and 140th St S Intersection. 1405 Fi ure 6 - Downstream Exhibit 4171'4 4162.;1 1: ,1 14 61407 3202 3208 31 3.24 Conclusion: 15 14120 / j)45;.,„ i 141 0.25 MILES DOWNSTREAM SO4 3.5.t4 1 2 .

FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN Drainage Concept The project site/each lot is <22,000 sf and therefore is required to apply the King County LID Standard OR Small Lot Flow Control BMPs per section C.1.2.9.2.3 of the KCSWDM. We have chosen Small Lot Flow Control BMPs.

Full Dispersion. The site area is limited due to limited flowpath space as is typical of an urban neighborhood. As a result, Full Dispersion was found to be not feasible. 2. Full Infiltration - Site/Soil conditions are of that typical of Vashon Aged Glacial Till. These soils have poor infiltration capabilities. Per the Geotech recommendations (see Geotech report in Appendix D, section "3.4 Infiltration Conditions") Full infiltration is not feasible. 3. Limited infiltration - Site/Soil conditions are of that typical of Vashon Aged Glacial Till. These soils have poor infiltration capabilities. Per the Geotech recommendations (see Geotech report in Appendix D, section "3.4 Infiltration Conditions") Limited infiltration is not feasible. 4. Bioretention - Site/Soil conditions are of that typical of Vashon Aged Glacial Till. These soils have poor infiltration capabilities. Per the Geotech recommendations (see Geotech report in Appendix D, section "3.4 Infiltration Conditions") Limited infiltration is not feasible. 5. Permeable Pavement Site/Soil conditions are of that typical of Vashon Aged Glacial Till. These soils have poor infiltration capabilities. Per the Geotech recommendations (see Geotech report in Appendix D, section "3.4 Infiltration Conditions") Limited infiltration is not feasible. 6.Basic Dispersion - The site area is limited due to limited flowpath space as is typical of an urban neighborhood. There are also concerns about the steep embankment on the frontage of the property. As a result, Basic Dispersion was found to be not feasible. 7. Perforated Pipe Connection - Feasible Due to the site's urban setting and limited flowpath lengths and the soil type, which doesn't allow infiltration facilities, A perforated pipe connection was chosen as a Stormwater BMP. Perforated pipe connections are capable of conveying concentrated runoff from impervious surfaces directly to local drainage systems, as is proposed on site. 17 Each proposed residence roof downspout and footing draings will be tight -lined to catch basin/area drain and then a perforated pipe connection before connecting into an existing catch basin along the project frontage on 34th Ave S. The proposed driveways will disperse into the existing ditching along the southwest side of 34th Ave S, as it did in the existing conditions.

C-23). The intent of these instructions is to explain to future property owners, the purpose of the BMP and how it must be maintained and operated. These instructions are intended to be a minimum; DPER may require additional instructions based on site -specific 7 2016 Surface Water Design Manual — Appendix C 4/24/2016 :C-105 SECTION C.2 FLOW CONTROL BMPs conditions. Also, as the. County gains more experience with the maintenance and operation of these BMPs, future updates to the instructions will be posted on King County's Surface Water Design Manual website. A reproducible copy of the instructions, prepared for inclusion with the declaration of covenant, is located in Reference M. ❑ TEXT OF INSTRUCTIONS Your property contains a stomtwater management flow control BMP (best management practice) called a "perforated pipe connection," which was installed to reduce the stomrwater runoff impacts of some or all of the impervious surface on your property. A perforated pipe connection is a length of drainage conveyance pipe with holes in the bottom, designed to "leak" runoff, conveyed by the pipe, into a gravel filled trench where it can be soaked into the surrounding soil. The connection is intended to provide opportunity for infiltration of any runoff that is being conveyed from an impervious surface (usually a roof) to a local drainage system such as a ditch or roadway pipe system. The size and composition of the perforated pipe connection as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. The soil overtop of the perforated portion of the system must not be compacted or covered with impervious materials. • • Appendix C CSPPP • • 27 CESCL REQUIREMENT A Certified Erosion and Sediment Control Specialist shall be identified in the Construction SWPPP and shall be onsite or oncall at all times. Certification may be obtained by an approved training program that meets the erosion and sediment control training criteria established by Ecology. If a preconstruction meeting is held, this person shall attend. See attached BMPC16O Certified Erosion and Sediment Control Lead (CESCL) CESCL 24hr Contact number: Fax number: Address: ELEMENT 1: MARK CLEARING LIMITS • Prior to beginning land disturbing activities, including clearing and grading, all clearing limits, sensitive areas and their buffers, and trees that are to be preserved within the construction area should be clearly marked, both in the field and on the plans, to prevent damage and offsite impacts. • Plastic, metal, or stake wire fence may be used to mark the clearing limits. • The duff layer, native topsoil, and natural vegetation shall be retained in an undisturbed state to the maximum extent practicable. If it is not practicable to retain the duff layer in place, it should be stockpiled onsite, covered to prevent erosion, and replaced immediately upon completion of the ground disturbing activities. Element #1 BMP Description X C101 Preservin • Natural Vegetation X C102 Buffer Zones X C103 High Visibility Plastic or Metal Fence X C104 Stake and Wire Fence Construction and silt fencing will be used to delineate the limits of clearing for the project. ELEMENT 2: ESTABLISH CONSTRUCTION ACCESS • Construction vehicle access and exit shall be limited to one route if possible. • Access points shall be stabilized with quarry spalls or crushed rock to minimize the tracking of sediment onto public roads. • Wheel wash or tire baths should be located onsite, if applicable. • Public roads shall be cleaned thoroughly as needed to protect stormwater infrastructure and downstream water resources. Sediment shall be removed from roads by shoveling or pickup sweeping and shall be transported to a controlled sediment disposal area. Street washing will be allowed only after sediment is removed in this manner. 28 • Street wash wastewater shall be controlled by pumping back onsite, or otherwise be prevented from discharging untreated into systems tributary to state surface waters. Element #2 BMP Description X C105 Stabilized Construction Entrance C106 Wheel Wash C107 Construction Road/Parking Area Stabilization The proposed construction accesses will be from 34th Ave S on the east property line. ELEMENT 3: CONTROL FLOW RATES • Properties and waterways downstream from development sites shall be protected from erosion due to increases in the volume, velocity, and peak flow rate of stormwater runoff from the project site, as required by local plan approval authority. • Downstream analysis is necessary ifchanges in flows could impair or alter conveyance systems, stream banks, bed sediment or aquatic habitat. See Chapter 3 for offsite analysis guidance. • Where necessary to comply with Minimum Requirement #7, stormwater retention/detention facilities shall be constructed as one of the first steps in grading. Detention facilities shall be functional prior to construction of site improvements (e.g. impervious surfaces). • The local permitting agency may require pond designs that provide additional or different stormwater flow control if necessary to address local conditions or to protect properties and • waterways downstream from erosion due to increases in the volume, velocity, and peak flow rate of stormwater runoff from the project site. • If permanent infiltration ponds are used for flow control during construction, these facilities shall be protected from siltation during the construction phase and plans made for restoration after construction. Element #3 BMP Description C240 Sediment Trap C241 Temporary Sediment Pond ELEMENT 4: INSTALL SEDIMENT CONTROLS • Prior to leaving a construction site, or prior to discharge to an infiltration facility, stormwater runoff from disturbed areas shall pass through a sediment pond or other appropriate sediment removal BMP. Runoff from fully stabilized areas may be discharged without a sediment removal BMP, but must meet the flow control performance standard of Element #3, bullet #1. Full stabilization means concrete or asphalt paving; quarry spalls used as ditch lining; or the use of rolled erosion products, a bonded fiber matrix product, or vegetative cover in a manner that will fully prevent soil erosion. The local permitting authority should inspect and approve areas stabilized by means other than pavement or quarry spalls. • Sediment ponds, vegetated buffer strips, sediment barriers or filters, dikes, and other BMP's intended to trap sediment onsite shall be constructed as one of the first steps in grading. These BMP's shall be functional before other land disturbing activities take place. • • 29 • Earthen structures such as dams, dikes, and diversions shall be seeded and mulched according to the timing indicated in Element #5. • BMPs intended to trap sediment on site must be located in a manner to avoid interference with the movement of juvenile salmonids attempting to enter off -channel areas or drainages, often during nonstorm events, in response to rain event changes in stream elevation or wetted area.

At minimum, the project will be required to have downstream protection (compost socks, silt fencing, or equivalent), inlet protection, and appropriate cover measures. The proposed plan is intended as guidance and the Contractor shall be responsible for implementing and maintaining appropriate sediment controls based on changing site conditions. ELEMENT 5: STABILIZE SOILS • All exposed and unworked soils shall be stabilized by application of effective BMPs that protect the soil from the erosive forces of raindrop impact, flowing water, and wind. • Soils shall be stabilized as outlined below, where downstream water resources or stormwater infrastructure may be negatively affected by sediments (i.e., runoff discharges off the development site). • From October 1 through April 30, no soils shall remain exposed and unworked for more than 2 days. From May 1 to September 30, no soils shall remain exposed and unworked for more than 7 days. This condition applies to all onsite soils, whether at final grade or not. The local permitting authority may adjust these time limits if it can be shown that a development site's erosion or runoff potential justifies a different standard. • Applicable practices include, but are not limited to, compost addition, temporary and permanent seeding, sodding, mulching, plastic covering, soil application of polyacrylamide (PAM), early application of gravel base on areas to be paved, and dust control. • Soil stabilization measures selected should be appropriate for the time of year, site conditions, estimated duration of use, and potential water quality impacts that stabilization agents may have on downstream waters or ground water. • Soil stockpiles must be stabilized from erosion, protected with sediment -trapping measures, and located away from storm drains, waterways, or drainage channels. . 30 • Work on linear construction sites and activities, including right-of-way and easement clearing, roadway development, pipelines, and trenching for utilities, shall not exceed the capability of the individual contractor for his portion of the project to install the bedding materials, roadbeds, structures, pipelines, and/or utilities, and to re -stabilize the disturbed soils, in compliance with the applicable 2-day or 7-day criterion listed above.

ELEMENT 6: PROTECT SLOPES • Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. • Consider soil type and its potential for erosion. • Reduce slope runoff velocities by reducing the continuous length of slope with terracing and diversions, reduce slope steepness, and roughen slope surface. • Offsite stormwater (run-on) shall be diverted away from slopes and disturbed areas with interceptor dikes and swales. Offsite stormwater should be managed separately from stormwater generated on the site. • To prevent erosion, at the top of slopes collect drainage in pipe slope drains or protected channels. Temporary pipe slope drains shall handle the peak flow from a 10-year, 24-hour event; permanent slope drains shall be sized for a 25-year, 24-hour event. Check dams shall be used within channels that are cut down a slope. • Provide drainage to remove ground water intersecting the slope surface of exposed soil areas. • Stabilize soils on slopes, as specified in Element #5.

ELEMENT 7: PROTECT DRAIN INLETS • As needed to protect stormwater infrastructure and downstream water resources, all storm drain inlets made operable during construction shall be protected so that stormwater runoff shall not enter the conveyance system without first being filtered or treated to remove sediment. • All approach roads shall be kept clean, and all sediment and street wash water shall not be allowed to enter storm drains without prior and adequate treatment, unless treatment is provided before the storm drain discharges to waters of the State. Element #7 BMP Description X C220 Storm Drain Inlet Protection Both existing and proposed drain inlets shall be protected as required. ELEMENT 8: STABILIZE CHANNELS AND OUTLETS • All temporary onsite conveyance channels shall be designed, constructed and stabilized to prevent erosion from the peak 10-minute flow velocity from a Type 1 A 10-year 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate indicated by an approved continuous runoff model, increased by a factor of 1.6, may be used. • Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes and downstream reaches shall be provided at the outlets of all conveyance systems. Element #8 BMP Description C202 Channel Lining X C209 Outlet Protection Permanent conveyance channels shall be, at a minimum, lined with grass. Outlets to open drainage areas shall be lined with rip -rap. ELEMENT 9: CONTROL POLLUTANTS • All pollutants, including waste materials and demolition debris that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater: • Cover, containment, and protection from vandalism shall be provided for all chemicals, liquid products, petroleum products, and non -inert wastes present on the site (see Chapter 173-304 WAC for the definition of inert waste). Onsite fueling tanks shall include secondary containment. • Maintenance and repair of heavy equipment and vehicles involving oil changes, hydraulic system drain down, solvent and de -greasing cleaning operations, fuel tank drain down and removal, and other activities which may result in discharge or spillage of pollutants to the ground or into stormwater runoff must be conducted using spill prevention measures, such as drip pans. Contaminated surfaces shall be cleaned immediately following any discharge or spill incident. • • 32 Report all spills to 911. Emergency repairs may be performed onsite using temporary plastic placed beneath and, if raining, over the vehicle. • Wheel wash, or tire bath wastewater, shall be discharged to a separate onsite treatment system or to the sanitary sewer if allowed by the local wastewater authority. • Application of agricultural chemicals, including fertilizers and pesticides, shall be conducted in a manner and at application rates that will not result in Toss of chemical to stormwater runoff. Manufacturers' label recommendations shall be followed for application rates and procedures. • Management of pH -modifying sources shall prevent contamination of runoff and stormwater collected on the site. These sources include, but are not limited to, bulk cement, cement kiln dust, fly ash, new concrete washing and curing waters, waste streams generated from concrete grinding and sawing, exposed aggregate processes, and concrete pumping and mixer washout waters. • Construction sites with significant concrete work shall adjust the pH 'of stormwater if necessary to prevent violations of water quality standards. 33 Element #9 BMP Description X C151 Concrete Handling X C152 Sawcutting and Surfacing Pollution Prevention The Contractor shall be responsible for controlling pollutants from construction activities off the project site. ELEMENT 10: CONTROL DE -WATERING • All foundation, vault, and trench de -watering water, which has similar characteristics to stormwater runoff at the site, shall be discharged into a controlled conveyance system, prior to discharge to a sediment trap or sediment pond. Channels must be stabilized, as specified in Element #8. • Clean, non -turbid de -watering water, such as well -point ground water, can be discharged to systems tributary to state surface waters, as specified in Element #8, provided the de -watering flow does not cause erosion or flooding of the receiving waters. These clean waters should not be routed through sediment ponds with stormwater. • Highly turbid or otherwise contaminated dewatering water, such as from construction equipment operation, clamshell digging, concrete tremie pour, or work inside a cofferdam, shall be handled separately from stormwater at the site. • Other disposal options, depending on site constraints, may include: 1) infiltration, 2) transport offsite in vehicle, such as a vacuum flush truck, for legal disposal in a manner that does not pollute state waters, 3) onsite treatment using chemical treatment or other suitable treatment technologies, or 4) sanitary sewer discharge with local sewer district approval. The Contractor shall be responsible for discharging de -watering water in an appropriate manner. ELEMENT 11: MAINTAIN BMP's • All temporary and permanent erosion and sediment control BMP's shall be maintained and repaired as needed to assure continued performance of their intended function. All maintenance and repair shall be conducted in accordance with BMP's. • Sediment control BMP's shall be inspected weekly or after a runoff -producing storm event during the dry season and daily during the wet season. • All temporary erosion and sediment control BMP's shall be removed within 30 days after final site stabilization is achieved or after the temporary BMP's are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil areas resulting from removal of BMP's or vegetation shall be permanently stabilized. The Contractor shall be responsible for maintaining BMP's to assure performance of their intended function. ELEMENT 12: MANAGE THE PROJECT • Phasing of Construction - Development projects shall be phased where feasible in order to prevent soil erosion and, to the maximum extent practicable, the transport of sediment from the project site during construction. Revegetation of exposed areas and maintenance of that vegetation shall be an integral part of the clearing activities for any phase. • • 34 Clearing and grading activities for developments shall be permitted only if conducted pursuant to an approved site development plan (e.g., subdivision approval) that establishes permitted areas of clearing, grading, cutting, and filling. When establishing these permitted clearing and grading areas, consideration should be given to minimizing removal of existing trees and minimizing disturbance/compaction of native soils except as needed for building purposes. These permitted clearing and grading areas and any other areas required to preserve critical or sensitive areas, buffers, native growth protection easements, or tree retention areas as may be required by local jurisdictions, shall be delineated on the site plans and the development site. All plats shall include lot -specific grading plans, including information specified by the local permitting authority such as finished grades, finished floor elevations, buildable areas, and identified drainage outlets. This information would normally be submitted with the construction drawings, but may be required prior to preliminary plat approval. • Seasonal Work Limitations From October 1 through April 30, clearing, grading, and other soil disturbing activities shall only be permitted if shown to the satisfaction of the local permitting authority that silt -laden runoff will be prevented from leaving the construction site through a combination of the following: 1. Site conditions including existing vegetative coverage, slope, soil type and proximity to receiving waters; and 2. Limitations on activities and the extent of disturbed areas; and 3. Proposed erosion and sediment control measures. Based on the information provided, and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on site disturbance. If, during the course of any construction activity or soil disturbance during the seasonal limitation period, silt -laden runoff leaving the construction site causes a violation of the surface water quality standard or if clearing and grading limits or erosion and sediment control measures shown in the approved plan are not maintained, the local permitting authority may take enforcement action, including but not limited to a notice of violation, administrative order, fine/penalty, stop - work order, or correction notice. The following activities are exempt from the seasonal clearing and grading limitations: 1. Routine maintenance and necessary repair of erosion and sediment control BMP's; 2. Routine maintenance of public facilities or existing utility structures that do not (a) expose the soil or (b) result in the removal of the soil's vegetative cover; and Self-contained project sites, where there is complete infiltration of the water quality design event runoff within the site. 3. Local governments may restrict clearing and grading activities where site conditions may present a significant risk of impact to property or critical areas. Contact the local permitting authority for information on specific site restrictions. In Olympia, except where approved chemical treatment, full dispersion or infiltration is practiced, clearing, grading, and other soil disturbing activities are prohibited in all watersheds November through February, and in Green Cove, Percival, Woodard, and Ellis Creek watersheds between October through April. • Coordination with Utilities and Other Contractors The primary project proponent shall evaluate, with input from utilities and other contractors, the stormwater management requirements for the entire project, including the utilities, when preparing the Construction SWPPP. • Inspection and Monitoring All BMP's shall be inspected, maintained, and repaired as needed to assure continued performance of their intended function. Site inspections shall be conducted by a person who is knowledgeable in the principles and practices of erosion and sediment control. The person shall have the skills to (1) assess site conditions and construction activities that could impact stormwater runoff quality, and (2) assess erosion and sediment control measure effectiveness. • 35 A Certified Erosion and Sediment Control Specialist shall be identified in the construction SWPPP and shall be onsite or on -call at all times. Certification may be obtained an approved training program that meets the erosion and sediment control training criteria established by Ecology. If a pre -construction meeting is held, this person shall attend. Sampling and analysis of the stormwater discharges from a construction site may be necessary on a case - by -case basis to ensure compliance with standards. Monitoring and reporting requirements may be established by the local permitting authority when necessary. The following discharge standard applies: Runoff leaving the construction site shall be free of settle able solids, as measured with an Imhoff Cone and in accordance with Standard Methods for the Examination of Water and Wastewater, most recent edition, American Water Works Association. "Free of settle able solids" shall be defined as measuring less than 2.5 mUUhr, for storms up to the water quality design event.1 The following surface water standard applies: 1. For storms up to the water quality design event, turbidity downstream of a construction site may not increase more than 5 NTU, if upstream turbidity is 50 NTU or less, and may not increase more than 10 percent, if upstream turbidity is over 50 NTU. To the extent practicable, samples should be taken far enough downstream so that the construction site discharge has been well - mixed with the surface water. 2. Whenever inspection and/or monitoring reveals that the BMP's identified in the Construction SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMP's or design changes shall be implemented as soon as possible. • Maintaining an Updated Construction SWPPP - The SWPPP shall be retained onsite or within reasonable access to the site. The SWPPP shall be updated within 7 days to reflect any significant changes in the design, construction, operation, or maintenance at the construction site that have, or could have, a significant effect on the discharge of pollutants to waters of the state. The SWPPP shall be updated within 7 days if during inspections or investigations by site staff or local or state officials, it is determined that the SWPPP is ineffective in controlling pollutants such that applicable discharge or surface water standards violations are apparent. The objective is to control erosion and prevent sediment and other pollutants from leaving the site during the construction phase of a project. The Contractor shall be responsible for managing the construction phase of the project within reasonable applications of the guidelines of this section and the SWPPP.

(MGI) is pleased to submit this report describing the results of our geotechnical engineering evaluation of your proposed residential development in Tukwila, Washington. This report has been prepared for the exclusive use of Cary Lang Construction, and their consultants, for specific application to this project, in accordance with generally accepted geotechnical engineering practice. 1.0 SITE AND PROJECT DESCRIPTION The project site consists of an irregularly -shaped, 0.57-acre, residential parcel situated in close proximity to the transition between the city limits of SeaTac and Tukwila, Washington as shown on the enclosed Topographic and Location Map (Figure 1). The parcel has previously been developed, with the central portions of the site being occupied by an existing single-family residence, originally constructed in 1902. Access to the site is gained through 34'h Ave S, along an existing driveway towards the north end of the parcel. The remainder of the parcel is relegated as yard space. Past grading activities have evidently taken place onsite, with the west end of the parcel residing at a higher relative grade than that of adjacent residential sites immediately to the west. Improvement plans involve the clearing/stripping of the subject property, demolition of existing site features, and the redevelopment of the site for residential purposes. It is our understanding that a short -plat of the property is currently proposed, which would result in three developable lots. Roof -runoff from the proposed residences will be retained onsite if feasible.

Our exploration and evaluation program comprised the following elements: • Surface reconnaissance of the site; • Two test pit explorations (designated TP-1 and TP-2), advanced on April 6, 2018; and • A review of published geologic and seismologic maps and literature. Table 1 summarizes the approximate functional locations and termination depths of our subsurface explorations, and Figure 2 depicts their approximate relative locations. The following sections describe the procedures used for excavation of the test pits. TABLE 1 APPROXIMATE LOCATIONS AND DEPTHS OF EXPLORATIONS Exploration Functional Location • Termination Depth (feet) TP-1 TP-2 West of the existing residence South of the existing residence; towards the south end of the parcel 9 10' The specific number and locations of our explorations were selected in relation to the existing site features, under the constraints of surface access, underground utility conflicts, and budget considerations. It should be realized that the explorations performed and utilized for this evaluation reveal subsurface conditions only at discrete locations across the project site and that actual conditions in other areas could vary. Furthermore, the nature and extent of any such variations would not become evident until additional explorations are performed or until construction activities have begun. If significant variations are observed at that time, we may need to modify our conclusions and recommendations contained in this report to reflect the actual site conditions. 2.1 Test Pit Procedures Our exploratory test pits were excavated with a rubber -tired backhoe operated by an excavation contractor under subcontract to Cary Lang Construction. An engineering geologist from our firm observed the test pit excavations, collected soil samples, and logged the subsurface conditions. The enclosed test pit logs indicate the vertical sequence of soils and materials encountered in our test pits, based on our field classifications. Where a soil contact was observed to be gradational or undulating, our logs indicate the average contact depth. We estimated the relative density and consistency of the in -situ soils by means of the excavation characteristics and the stability of the test pit sidewalls. Our logs also indicate the approximate depths of any sidewall caving or groundwater seepage observed in the test pits. The soils were classified visually in general accordance with the system described in Figure A-1, which includes a key to the exploration logs. Summary logs of our explorations are included as Figures A-2 and A-3. Migizi Group, Inc.

The subject property is located within a densely populated residential area between Military Rd S and Tukwila International Blvd; approximately one -mile northeast of the Seattle -Tacoma International Airport. The east side of the parcel is bound by 34th Ave S, with its remaining sides contacting developed residential sites. The subject property has previously been developed, with the central portion of the site being occupied by an existing residence originally constructed in 1902. The remainder of the property is relegated as yard space. Topographically, the footprint of the existing residence resides within the relative high spot of the parcel, with the remainder of the property descending away from this location. Upwards of 10 feet of elevation change is observed over the extent of the parcel, with localized grade changes being less than 10 percent. Vegetation onsite is sparse, with the majority of the parcel having been resurfaced with recycled concrete. No hydrologic features were observed on site, such as seeps, springs, ponds and streams. As noted above, a seasonal ancillary stream channel is present immediately offsite to the east. 3.2 Soil Conditions Our test pit explorations revealed relatively consistent subgrade conditions across the project area, generally consisting of a variable amount of fill material overlying native, glacial till soils. Fill soils were generally encountered through a depth of ± 7 feet of both of our explorations, with the material ranging in composition between gravelly silty sand and fine sand with silt. Fill soils were generally encountered in medium dense condition. Glacial till soils were observed towards the lower reaches of both of our explorations, generally consisting of very dense gravelly silty sand. Tacoma, and the larger Puget Sound area in general, has been glaciated a number of times over the last 2.4 million years. The most recent of these glacial events, the Vashon Stade of the Fraser Glaciation, receded from this region approximately 13,500 years ago. The majority of near surface soils encountered within the Tacoma area are either directly associated with or have been physically altered by the Vashon glacial event. Glacial till is typically described as being a compact, coherent mixture of gravel, silt, clay and sand -sized clasts deposited along the base of glacial ice during a period of localized advancement. This material is generally encountered in a compact relative consistency given the fact that it was overridden by the ice mass shortly after deposition and is commonly underlain by advance outwash soils. In the Geologic Map of the Des Moines 7.5' Quadrangle, King County, Washington, as prepared by the U.S. Department of the Interior U.S. Geological Survey (USGS) (2004), the project site is mapped as containing Qvt, or Vashon-aged glacial till. Our subsurface explorations generally correspond with the mapping of the site performed by the USGS. Migizi Group, Inc. Page 3 of 11 • • Cary Lang Construction - Residential Development, 14213 34th Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 The enclosed exploration logs (Appendix A) provide a detailed description of the soil strata encountered in our subsurface explorations. 3.3 Groundwater Conditions We encountered moderate groundwater seepage at a depth of 10 feet in test pit exploration TP-2, which was performed towards the south end of the parcel. This depth corresponds with the contact with native, glacial till soils. Given the topographic location of the project area, we do not believe that this is indicative of actual groundwater elevations, but rather indicative of seasonally perched groundwater, trapped atop the relatively impervious glacial till soils. We do not anticipate that groundwater will be present in most project excavations, nor be a limiting factor in the proposed development. 3.4 Infiltration Conditions As indicated in the Soil Conditions section of this report, the site is underlain by upwards of 71/2 feet of imported fill material, transitioning to relatively impermeable glacial till soils with depth. As such, we do not interpret full or limited infiltration as being feasible for this project. Roof -runoff water from the proposed residences should be managed through dispersion, diverted to an existing system along 34th Ave S, or managed through another appropriate method. 3.5 Seismic Conditions Based on our analysis of subsurface exploration logs and our review of published geologic maps, we interpret the onsite soil conditions to generally correspond with site class D, as defined by Table 30.2-1 in ASCE 7, per the 2015 International Building Code (IBC). Using 2015 IBC information on the USGS Design Summary Report website, Risk Category I/II/III seismic parameters for the site are as follows: Ss = 1.494 g SMs = 1.494 g SDs = 0.996 g S1= 0.560 g SM1 = 0.839 g Sol = 0.560 g Using the 2015 IBC information, MCER Response Spectrum Graph on the USGS Design Summary Report website, Risk Category I/II/III, Sa at a period of 0.2 seconds is 1.49 g and Sa at a period of 1.0 seconds is 0.84 g. The Design Response Spectrum Graph from the same website, using the same IBC information and Risk Category, Sa at a period of 0.2 seconds is 1.00 g and Sa at a period of 1.0 seconds is 0.56 g. 3_6 Liquefaction Potential Liquefaction is a sudden increase in pore water pressure and a sudden loss of soil shear strength caused by shear strains, as could result from an earthquake. Research has shown that saturated, loose, fine to medium sands with a fines (silt and clay) content less than about 20 percent are most susceptible to liquefaction. No saturated, poorly consolidated granular soils were encountered throughout the course of our test pit explorations. We interpret site soils as having a low potential of liquefying during a large-scale seismic event. Migizi Group, Inc.

It is our understanding that a short -plat of the property is currently proposed, which would result in three developable lots. Roof -runoff from the proposed residences will be retained onsite if feasible. We offer these recommendations: • Feasibility: Based on our field explorations, research and analyses, the proposed structures appear feasible from a geotechnical standpoint. • Foundation Options: Foundation elements for the proposed residences should be constructed on medium dense or denser fill or native soils, or on structural fill bearing pads extending down to these soils. In our opinion, existing fill soils are suitable for foundation support and we anticipate that adequate bearing soils will be encountered within 2 feet of existing grade. Recommendations for Spread Footings are provided in Section 4.2. • Floor Options: Floor sections for the proposed residences should bear on medium dense or denser fill or native soils or on a properly compacted structural fill subbase. In our opinion, existing fill soils are suitable for slab support, and we anticipate that adequate bearing soils will be encountered within two feet of existing grade. Recommendations for slab -on -grade floors are included in Section 4.3. Fill underlying floor slabs should be compacted to 95 percent (ASTM:D-1557). The following sections of this report present our specific geotechnical conclusions and recommendations concerning site preparation, spread footings, slab -on -grade floors, asphalt pavement, and structural fill. The Washington State Department of Transportation (WSDOT) Standard Specifications and Standard Plans cited herein refer to WSDOT publications M41-10, Standard Specifications for Road, Bridge, and Municipal Construction, and M21-01, Standard Plans for Road, Bridge, and Municipal Construction, respectively. 4_1 Site Preparation Preparation of the project site should involve erosion control, temporary drainage, clearing, stripping, excavations, cutting, subgrade compaction, and filling. Erosion Control: Before new construction begins, an appropriate erosion control system should be installed. This system should collect and filter all surface water runoff through silt fencing. We anticipate a system of berms and drainage ditches around construction areas will provide an adequate collection system. Silt fencing fabric should meet the requirements of WSDOT Standard Specification 9-33.2 Table 3. In addition, silt fencing should embed a minimum of 6 inches below existing grade. An erosion control system requires occasional observation and maintenance. Specifically, holes in the filter and areas where the filter has shifted above ground surface should be replaced or repaired as soon as they are identified. Migizi Group, Inc. Page 5 of 11 • • Cary Lang Construction - Residential Development, 14213 34th Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 Temporary Drainage: We recommend intercepting and diverting any potential sources of surface or near -surface water within the construction zones before stripping begins. Because the selection of an appropriate drainage system will depend on the water quantity, season, weather conditions, construction sequence, and contractor's methods, final decisions regarding drainage systems are best made in the field at the time of construction. Based on our current understanding of the construction plans, surface and subsurface conditions, we anticipate that curbs, berms, or ditches placed around the work areas will adequately intercept surface water runoff. Clearing and Stripping: After surface and near -surface water sources have been controlled, sod, topsoil, and root -rich soil should be stripped from the site. Our subsurface explorations indicate that there is a minimal organic horizon across the project site, and we do not anticipate that significant stripping will be necessary. Site Excavations: Based on our explorations, we expect that site excavations will predominately encounter moderately consolidated fill soils at shallow elevations, and densely consolidated glacial till soils with depth, both of which can be readily excavated using standard excavation equipment. Dewatering: Our explorations encountered moderate seepage in the vicinity of test pit exploration TP-2, at a depth of 10 feet, along the contact with glacial till soils. We anticipate that this is indicative of seasonally perched groundwater and not representative of actual groundwater elevations. We do not expect groundwater to be encountered in project excavations, however, if groundwater is encountered, we anticipate that an internal system of ditches, sump holes, and pumps will be adequate to temporarily dewater excavations. Temporary Cut Slopes: All temporary soil slopes associated with site cutting or excavations should be adequately inclined to prevent sloughing and collapse. Temporary cut slopes in site soils should be no steeper than 11/2H:1V, and should conform to Washington Industrial Safety and Health Act (WISHA) regulations. Subgrade Compaction: Exposed subgrades for the foundation of the proposed residences should be compacted to a firm, unyielding state before new concrete or fill soils are placed. Any localized zones of looser granular soils observed within a subgrade should be compacted to a density commensurate with the surrounding soils. In contrast, any organic, soft, or pumping soils observed within a subgrade should be overexcavated and replaced with a suitable structural fill material. Site Filling: Our conclusions regarding the reuse of onsite soils and our comments regarding wet - weather filling are presented subsequently. Regardless of soil type, all fill should be placed and compacted according to our recommendations presented in the Structural Fill section of this report. Specifically, building pad fill soil should be compacted to a uniform density of at least 95 percent (based on ASTM:D-1557). Migizi Group, Inc. Page 6 of 11 Cary Lang Construction — Residential Development, 14213 34th Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 Onsite Soils: We offer the following evaluation of these onsite soils in relation to potential use as structural fill: • Surficial Organic Soil and Organic -Rich Fill Soils: Where encountered, surficial organic soils like duff, topsoil, root -rich soil, and organic -rich fill soils are not suitable for use as structural fill under any circumstances, due to high organic content. Consequently, this material can be used only for non-structural purposes, such as in landscaping areas. • Existing Fill Material: Underlying a surface mantle of sod and topsoil, existing fill material was encountered, being comprised of gravelly silty sand and fine sand with silt, extending upwards of 71/2 feet below grade across much of the site. These soils are moderately moisture sensitive and will become increasingly difficult to reuse during wet weather conditions. If reuse is planned, care should be taken while stockpiling in order to avoid saturation/over-saturation of the material and moisture conditioning should be expected. Permanent Slopes: All permanent cut slopes and fill slopes should be adequately inclined to reduce long-term raveling, sloughing, and erosion. We generally recommend that no permanent slopes be steeper than 2H:1V. For all soil types, the use of flatter slopes (such as 22H:1V) would further reduce long-term erosion and facilitate revegetation. Slope Protection: We recommend that a permanent berm, swale, or curb be constructed along the top edge of all permanent slopes to intercept surface flow. Also, a hardy vegetative groundcover should be established as soon as feasible, to further protect the slopes from runoff water erosion. Alternatively, permanent slopes could be armored with quarry spalls or a geosynthetic erosion mat. 4_2 Spread Footings In our opinion, conventional spread footings will provide adequate support for the proposed residences if the subgrade is properly prepared. We offer the following comments and recommendations for spread footing design. Footing Depths and Widths: For frost and erosion protection, the bases of all exterior footings should bear at least 18 inches below adjacent outside grades, whereas the bases of interior footings need bear only 12 inches below the surrounding slab surface level. To reduce post -construction settlements, continuous (wall) and isolated (column) footings should be at least 16 and 24 inches wide, respectively. Bearing Subgrades: Footings should bear on medium dense or denser fill or native soils which have been stripped of surficial organic soils and vigorously surface compacted, or on properly compacted structural fill bearing pads. In our opinion, existing fill soils are suitable for foundation support, and we anticipate that adequate bearing soils will be encountered within 2 feet of existing grade. Migizi Group, Inc. Page 7 of 11 • • Cary Lang Construction — Residential Development, 14213 34th Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 In general, before footing concrete is placed, any localized zones of loose soils exposed across the footing subgrades should be compacted to a firm, unyielding condition, and any localized zones of soft, organic, or debris -laden soils should be overexcavated and replaced with suitable structural fill. Lateral Overexcavations: Because foundation stresses are transferred outward as well as downward into the bearing soils, all structural fill placed under footings should extend horizontally outward from the edge of each footing. This horizontal distance should be equal to the depth of placed fill. Therefore, placed fill that extends 3 feet below the footing base should also extend 3 feet outward from the footing edges. Subgrade Observation: All footing subgrades should consist of firm, unyielding, native soils, or structural fill materials that have been compacted to a density of at least 95 percent (based on ASTM:D-1557). Footings should never be cast atop loose, soft, or frozen soil, slough, debris, existing uncontrolled fill, or surfaces covered by standing water. Bearing Pressures: In our opinion, for static loading, footings that bear on moderately consolidated recessional outwash soils can be designed for a maximum allowable soil bearing pressure of 1,500 psf. A one-third increase in allowable soil bearing capacity may be used for short-term loads created by seismic or wind related activities. Footing Settlements: Assuming that structural fill soils are compacted to a medium dense or denser state, we estimate that total post -construction settlements of properly designed footings bearing on properly prepared subgrades will not exceed 1 inch. Differential settlements for comparably loaded elements may approach one-half of the actual total settlement over horizontal distances of approximately 50 feet. Footing Backfill: To provide erosion protection and lateral load resistance, we recommend that all footing excavations be backfilled on both sides of the footings and stemwalls after the concrete has cured. Either imported structural fill or non -organic onsite soils can be used for this purpose, contingent on suitable moisture content at the time of placement. Regardless of soil type, all footing backfill soil should be compacted to a density of at least 90 percent (based on ASTM:D-1557). Lateral Resistance: Footings that have been properly backfilled as recommended above will resist lateral movements by means of passive earth pressure and base friction. We recommend using an allowable passive earth pressure of 225 psf and an allowable base friction coefficient of 0.35 for site soils. 4.3 Slab -On -Grade Floors In our opinion, soil -supported slab -on -grade floors can be used in the proposed residences if the subgrades are properly prepared. Floor sections for the proposed structures should bear on medium dense or denser fill or native soils or on a properly compacted structural fill subbase. In our opinion, existing fill soils are suitable for slab support, and we anticipate that adequate bearing soils will be encountered within two feet of existing grade. We offer the following comments and recommendations concerning slab -on -grade floors. Migizi Group, Inc. Page 8 of 11 • . Cary Lang Construction — Residential Development, 14213 34'h Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 Floor Subbase: Surface compaction of all slab subgrades is recommended. If a subbase is required, it should be compacted to a density of at least 95 percent (based on ASTM:D-1557). Capillary Break and Vapor Barrier: To retard the upward wicking of moisture beneath the floor slab, we recommend that a capillary break be placed over the subgrade. Ideally, this capillary break would consist of a 4-inch-thick layer of pea gravel or other clean, uniform, well-rounded gravel, such as "Gravel Backfill for Drains" per WSDOT Standard Specification 9-03.12(4), but clean angular gravel can be used if it adequately prevents capillary wicking. In addition, a layer of plastic sheeting (such as Crosstuff, Visqueen, or Moistop) should be placed over the capillary break to serve as a vapor barrier. During subsequent casting of the concrete slab, the contractor should exercise care to avoid puncturing this vapor barrier. Vertical Deflections: Due to elastic compression of subgrades, soil -supported slab -on -grade floors can deflect downwards when vertical loads are applied. In our opinion, a subgrade reaction modulus of 250 pounds per cubic inch can be used to estimate such deflections. 4.4 Structural Fill The term "structural fill" refers to any material placed under foundations, retaining walls, slab -on - grade floors, sidewalks, pavements, and other structures. Our comments, conclusions, and recommendations concerning structural fill are presented in the following paragraphs. Materials: Typical structural fill materials include clean sand, gravel, pea gravel, washed rock, crushed rock, well -graded mixtures of sand and gravel (commonly called "gravel borrow" or "pit - run"), and miscellaneous mixtures of silt, sand, and gravel. Recycled asphalt, concrete, and glass, which are derived from pulverizing the parent materials, are also potentially useful as structural fill in certain applications. Soils used for structural fill should not contain any organic matter or debris, nor any individual particles greater than about 6 inches in diameter. Fill Placement: Clean sand, gravel, crushed rock, soil mixtures, and recycled materials should be placed in horizontal lifts not exceeding 8 inches in loose thickness, and each lift should be thoroughly compacted with a mechanical compactor. Compaction Criteria: Using the Modified Proctor test (ASTM:D-1557) as a standard, we recommend that structural fill used for various onsite applications be compacted to the following minimum densities: Fill Application Footing subgrade and bearing pad Foundation backfill Slab -on -grade floor subgrade and subbase Minimum Compaction 95 percent 90 percent 95 percent Subgrade Observation and Compaction Testing: Regardless of material or location, all structural fill should be placed over firm, unyielding subgrades prepared in accordance with the Site Preparation section of this report. The condition of all subgrades should be observed by geotechnical personnel Migizi Group, Inc. Page 9 of 11 • • Cary Lang Construction — Residential Development, 14213 34th Ave S, Tukwila, WA Geotechnical Engineering Report April 26, 2018 P1276-T18 before filling or construction begins. Also, fill soil compaction should be verified by means of in -place density tests performed during fill placement so that adequacy of soil compaction efforts may be evaluated as earthwork progresses. Soil Moisture Considerations: The suitability of soils used for structural fill depends primarily on their grain -size distribution and moisture content when they are placed. As the "fines" content (that soil fraction passing the U.S. No. 200 Sieve) increases, soils become more sensitive to small changes in moisture content. Soils containing more than about 5 percent fines (by weight) cannot be consistently compacted to a firm, unyielding condition when the moisture content is more than 2 percentage points above or below optimum. For fill placement during wet -weather site work, we recommend using "clean" fill, which refers to soils that have a fines content of 5 percent or less (by weight) based on the soil fraction passing the U.S. No. 4 Sieve. 5.0 RECOMMENDED ADDITIONAL SERVICES Because the future performance and integrity of the structural elements will depend largely on proper site preparation, drainage, fill placement, and construction procedures, monitoring and testing by experienced geotechnical personnel should be considered an integral part of the construction process. Subsequently, we recommend that MGI be retained to provide the following post -report services: • Review all construction plans and specifications to verify that our design criteria presented in this report have been properly integrated into the design; • Prepare a letter summarizing all review comments (if required); • Check all completed subgrades for footings and slab -on -grade floors before concrete is poured, in order to verify their bearing capacity; and • Prepare a post -construction letter summarizing all field observations, inspections, and test results (if required).

Also, because the future performance and integrity of the project elements depend largely on proper initial site preparation, drainage, and construction procedures, monitoring and testing by experienced geotechnical personnel should be considered an integral part of the construction process. MGI is available to provide geotechnical monitoring of soils throughout construction. We appreciate the opportunity to be of service on this project.
