The site will be used to store semi -truck and tractor trailers. The lot fronts East Marginal Way on the west and is bounded to the east by Airport Way South. Sound Transit has a thirty- two foot easement for the overhead guideway that traverses the site from the northeast corner to the southwest corner. Three concrete pylons support the elevated guideway across the site. This project involves an estimated 500 cubic yards of cut and 2,500 cubic yards of fill. Five feet of Type II landscaping is required along East Marginal. The project will also include a boundary line adjustment to clean up some odd shaped lots. No other development is proposed.

SM Page 1 of 3 04/08/2008 H: \Stacy's Current Planning\E08 -003 McConkey- Medica\E08 -003 SR.doc SEPA Planned Action — E08110 • McConkey/ Tukwila Medica Decision Criteria: The site is within the project area for the Tukwila Manufacturing/Industrial Center Integrated GMA Implementation Plan and Environmental Impact Statement. The Integrated Plan and Final EIS were completed in March, 1998. Both the Duwamish Corridor Redevelopment EIS and the Tukwila Manufacturing/Industrial Center Integrated GMA Implementation Plan and Environmental Impact Statement analyze the environmental impacts of a range of development and redevelopment alternatives on properties in the MIC corridor. The determination of whether a project fits the Planned Action criteria is divided into two phases. I. In the first phase, a determination is made whether the project satisfies all of the following characteristics to first qualify as a Planned Action: A. The action is a `permitted use" located within the MIC /L (TMC 18.36.020) and MIC /H (TMC 18.38.020) zones and/or is an accessory use (TMC 18.36.030 and 18.38.030 respectively). Response: The zoning is Manufacturing Industrial Center/Heavy. The project is to grade and pave an existing lot to use it for storage of semi -truck and tractor trailers. The Director made a determination (attached) that the use is similar to a truck terminal and, as such, is a permitted use in the MIC/H. B. The action is: a. not an "essential public facility" as defined in RCW 36.70.200 and TMC 18.06.270, b. not a conditional or unclassified use, in the respective MIC /L or MIC /H zones, c. not a development, any portion of which includes shoreline modifications waterward of the ordinary high water mark, d. not a development associated with 16th Avenue South Bridge construction activities. Response: The project is not an essential public facility, is not a conditional or unclassified use in the MIC/H as defined by the zoning code, is not located waterward of the ordinary high water mark, and does not involve the 16th Avenue S. Bridge. II. Once the project has met the initial test to qualify as a planned action, it must then show the following: A. Will all of the impacts of the proposal be mitigated by the time the project is complete? Please document all mitigation measures, using attachments if necessary. Response: The project will follow the recommendations laid out in the Geotechnical Report dated December 26, 2007 by Geotech Consultants, Inc., and the Technical Information Report dated February 11, 2008 by Barghausen Consulting Engineers, Inc. as well as comply with the conditions of permit PW08 -030. B. Is the proposal consistent with the applicable sections of the Tukwila Comprehensive Plan? SM Page 2 of 3 04/08/2008 H:\Stacy's Current Planning\E08 -003 McConkey- Medica\E08 -003 SR.doc SEPA Planned Action — E103 McConkey/ Tukwila Medics TMC 21.04.154 requires that the Comprehensive Plan policies that are to be reviewed are those identified in the "Integrated GMA Implementation Plan and Environmental Impact Statement for the Tukwila Manufacturing/Industrial Center." Comprehensive Plan Consistency Criteria that apply, includes: Policy 11.1.5: Allow uses that are commonly associated with manufacturing and industry, including those directly supporting such activity, such as offices and laboratories, while limiting unrelated uses. Response: The site will be used to store semi -truck and tractor trailers. This is similar in use to a truck terminal, which is a use permitted in the code. Policy 5.1.2: Manufacturing /Industrial Center Environment: In the Manufacturing /Industrial Center Environment, priority shall be given to the following: • Redevelopment of under - utilized areas and development of intensive commercial and industrial activities; and • Enhancement and restoration of access to the river; and • Protection and restoration of natural environment features and riverbank characteristics, where comparable with development. The following area shall be designated as the Manufacturing /Industrial Center Environment: • The entire shoreline zone from the northern City limits upstream to the Highway 99 bridge. Response: As a vacant lot, it is under - utilized. With the Link Light Rail guideway traversing the site, it has limited development potential. This site is in the Manufacturing/Industrial Center environment. Policy 4.1.2: For new development and for some redevelopment, control peak runoff rates to predevelopment levels and minimize the effects of the small, frequent storm events. Maintain water quality to predevelopment levels; and prohibit direct discharge to downstream drainage systems unless allowed by specific regulations. Response: The stormwater runoff system is designed to meet the requirements of the 1998 KCSWDM for Basic Water Quality. Policy 4.1.4: For new and existing development, prevent illicit discharge to downstream drainage systems. Response: The stormwater runoff system is designed to meet the requirements of the 1998 KCSWDM for Basic Water Quality. Recommendation: Determine that the proposed site improvements fall within the scope of the Planned Action SEPA.

The scope of our work consisted of exploring site surface and subsurface conditions, reviewing subsurface exploration Togs prepared by others in the site vicinity, and then developing this report to provide recommendations for pavement design and assessing the potential for on -site infiltration of stormwater. This work was authorized by your acceptance of our proposal dated November 19, 2007. 'Redevelopment of the property is in the early feasibility planning stage, and detailed plans were not available to us at the time of this report. However, from our discussions with Fred McConkey, of East Marginal Way Properties, we understand that the existing gravel- surfaced, nearly -level vacant site will be resurfaced with asphalt concrete pavement to provide parking for various vehicles, including large semi - tractor trucks and trailers. An old house on the property was recently demolished and site graded nearly level. We anticipate that several feet of new structural fill will be required to raise and level the site for use as a paved parking lot. In the future, one or more commercial buildings may be constructed on the site. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, illustrates the general location of the site, which is just south of the South Boeing Access Road and Airport Way South. The site is an approximately trapezoidal- shaped, vacant property. The lot has frontage along the northbound lane of East Marginal Way South and is bounded to the east by Airport Way South. Adjacent commercial - industrial properties are situated to the north and south of the property. At one time, three single - family residences occupied the site, with the last building having been removed within the last few years. The site is currently used for temporary truck parking. The Sound Transit Light Rail traverses across the site on an elevated rail curving from the northeast corner to the southwest corner. Three large concrete pylons support the elevated rail across the site. East Marginal Way PropertitikLC December 26, 2007 • JN 07077 Page 2 The subject property measures roughly 200 to 235 feet on all sides and is nearly level, with grades ranging from about elevation 20 feet near the sidewalk on East Marginal Way South down to about elevation 16 feet over most of the site. The lot is surfaced mostly with crushed rock, recycled concrete and crushed brick ranging from a few inches thick to as much as 12 inches. The south - southeast portion site is lower, and was covered with a shallow pond of accumulated surface water at the time of our field work. During our explorations in this area we noted the presence of several buried utilities, including several electrical power lines, abandoned plastic water lines, and a sanitary sewer line. SUBSURFACE The subsurface conditions were evaluated by reviewing explorations completed by others in the site vicinity, including borings completed by others for the new concrete pylons for the Sound Transit rail line. We also explored the site by excavating nine backhoe test pits (TP -1 through TP- 9) at the approximate locations shown on the Exploration Site Plan, Plate 2. All of the test pit explorations were completed to depths ranging from 3.5 to 10 feet below ground surface (bgs) due to saturated, caving alluvial soils. The field exploration program was based upon the proposed construction, subsurface conditions revealed during our review of previous explorations completed by others, our own site explorations, the presence of underground utilities, and the scope of work outlined in our proposal. Our review of a number of borings and test pits completed over a number of years by others, indicates that the site is underlain by alluvial soils (alluvium) deposited by past meanders of the ancestral and existing Duwamish River. Borings completed for the center pylon for the Sound Transit rail lines (middle of the site) indicate that the alluvial soils, consisting of saturated, loose - soft, interlayered silt and sand soils extend to about 125 feet bgs, where bedrock is first encountered. This information is consistent with our explorations and previous experience in this area of East Marginal Way South. Our initial exploration at the site, on December 17, 2007, was in Test Pit TP -1 located near the entrance to the site at the northwest corner of the property just off of East Marginal Way South. We encountered undocumented electrical power lines buried at shallow depth in TP -1 and decided to forego further backhoe test pits until such time as a private utility locate could be completed on the site. The private locate was completed on December 21, 2007 and several other unmarked buried utilities were found. With the location of the buried utilities located and marked, we completed the remaining eight test pits (TP- 2 through 9) on December 21, 2007. A rubber -tired backhoe subcontracted to Geotech Consultants, Inc. was used for all our test pit explorations. An engineering geologist from our staff observed the exploration process, logged the test pits, and obtained representative samples of the soil encountered. The Test Pit Logs for TP -1 through TP -9 are attached as an Appendix to this report. As aforementioned, the surface of the site is covered with crushed rock, crushed - recycled concrete, and broken brick. This provides a temporary driving and parking surface for mostly large semi - trucks (tractors and trailers). The surfacing ranges from a few inches to nearly a foot thick depending on location. Due to constant truck traffic at the site, the surfacing is in a medium dense to dense condition. No areas of unstable or "pumping" subgrade soil were observed where the ground surface was visible outside of the area of standing. water. GEOTECH CONSULTANTS, INC. East Marginal Way PropertitaLC December 26, 2007 • JN 07077 Page 3 Beneath the crushed surfacing layer in all out test pits is a variable thickness of man - placed fill ranging from less than a foot thick in TP -5 (near the center of the site) to 4 feet thick in TP -1 (at entrance to site). In general, the fill was thinner to the east and thickens towards the west. Typically, the fill in TP -1 through TP -3 (all on the west side of the site) consists of silty sand mixed with gravel, cobbles, occasional silt, and sometimes plastic, asphalt- concrete, and miscellaneous material (wood, nails, etc.), in generally a medium -dense condition. In TP -4 through TP -8, the fill consists of sandy gravel and crushed rock in a wet, medium -dense condition. The fill in TP -9 consists of rock spalls and crushed rock placed over a synthetic geotextile (woven fabric). TP -9 was excavated on the south side of the site near the pond; we attempted several test pits along the south side of the site but were limited by the presence of buried sanitary sewer and electrical power conduit, rock spalls /geotextile, and pond water that rushed into the test pits. We were only successful in penetrating the geotextile in TP -9 but could not excavate deeper than 2.5 feet below ground surface (bgs) due to pond water rushing into the test pit. Underlying the fill at the site is native Duwamish River Valley alluvium. The alluvium consists of soil deposited by past meanders of the Duwamish River, including low- energy deposits of silt and clay, and high- energy deposits of sand and gravel. These soils have accumulated since the end of the last period of glaciation in the Puget Sound region, about 14,000 years ago. According to our review of boring logs completed in the vicinity of the site by others, including one boring for the center Sound Transit rail pylon, the alluvium is underlain by weathered bedrock. The thickness of alluvium will likely be less to the east (40 feet bgs or less) and thicker to the west (125 feet bgs or deeper), based on the underlying west- sloping bedrock surface. Our explorations at the site encountered fine - grained silty sand alluvium immediately under the man - placed fill to depths ranging from roughly 5 to 7 feet bgs. This silty sand alluvium gradually became siltier with depth and grades typically to interlayered silt and silty sand. Our explorations and experience indicates that the upper silty sand unit is somewhat firm (but loose) and wet. However, once the underlying interlayered silt and silty sand unit is encountered, these soils become fully saturated and are in a very loose /very soft condition to their full depth. Generally, our explorations could not advance deeper than 7.5 to 10 feet bgs due to severe caving of the test pit side walls in the saturated, very loose /very soft soils. The stratification lines on the Togs represent the approximate boundaries between soil types at the exploration locations. The actual transition between soil types are typically gradual, and subsurface conditions will substantially vary between exploration locations. The logs provide specific subsurface information only at the locations explored. The relative densities and moisture descriptions indicated on the Togs are interpretive descriptions based on the conditions observed during the explorations. GROUNDWATER Substantial groundwater seepage was encountered in all of our explorations, except at TP -1 (completed at shallow depth due to buried electrical lines), TP -8 (completed only to 7.5 feet bgs), and TP -9 where rapid inflow of pond water prevented deeper exploration. Generally, the test pits show that the groundwater level ranges from 6.5 feet bgs to 8.5 feet bgs, with the shallower levels to the east. However, the site grades are higher to the west and taper eastward down a couple of feet. Thus, we suspect that static groundwater during our site explorations on December 17 and 21, 2007 is relatively level and at about Elevation 8 feet. The static water level may be under tidal influence and thus should vary with date and time for any given period of measure. GEOTECH CONSULTANTS, INC. East Marginal Way Propertii.LC December 26, 2007 JN 07077 Page 4 The shallow surface water ponded in the southeast portion of the site, in our opinion, does not represent the static water level, but is likely water perched upon relatively silty, fill soil, which was probably placed during construction of the overhead Sound Transit rail line. CONCLUSIONS AND RECOMMENDATIONS GENERAL The explorations generally found relative firm, medium - dense, man - placed fill to depths of about one foot to 4 feet bgs, with the fill thinning to the east and thickening to the west. The fill overlies Duwamish River Valley alluvium that extends to depths ranging from perhaps 40 feet bgs to possibly deeper than 125 feet bgs. Under the alluvium is bedrock. We expect that most of the man- placed existing fill will remain to provide a base upon which the site can be leveled and pavement subgrade conditions can be improved. In our opinion, site leveling and new pavement subgrade improvement should consist of the placement and compaction of granular structural fill, placed and compacted in accordance to our recommendations below. In order to provide a solid subgrade for pavement to support large trucks, we recommend that there be a total thickness of no less than 2.5 feet of fill overlying the alluvial soils. We strongly recommend that the new fill be placed in dry weather conditions. If, however, the site will be developed for parking in the wet season, we recommend that the pond be drained, that a significant thickness of rock spells be placed over a heavy -duty geotextile material, and that all mud and wet - saturated surficial soils be removed prior to placing new structural fill. The structural fill placed above the existing grade can consist of a variety of materials, but potential fill materials should be approved by the geotechnical engineer before use at the site. In general, we recommend that new structural fill consist of a natural or manmade granular material having a gravel content of at least 30 percent. If semi - trailers will be stored on the site, it would be prudent to provide concrete pads for the trailer outriggers. This prevents deformation of the asphalt under the concentrated outrigger loads. Groundwater was encountered at depths of about 6.5 feet bgs to 8.5 feet bgs during our explorations. As such, the placement of deep- buried utilities should be avoided as severe caving of utility trenches or any excavations deeper than about 5 to 6 feet deep should be expected. Dewatering of deeper excavations may also be needed. The high silt content of the on -site soils and the relatively shallow groundwater depth will make on- site infiltration of stormwater unfeasible. We expect that the site will need to be graded and filled to allow surface water drainage to City of Tukwila- approved stormwater discharge points. The saturated soils that underlie the water table are susceptible to seismic liquefaction. If lightly - loaded commercial buildings are built on the site in the future, it should be possible to support them on heavily- reinforced conventional foundations placed over several feet of new structural fill. This type of a foundation system is resistant to excessive differential settlement under building loads, and should prevent catastrophic settlement from seismic liquefaction. Taller, or settlement- sensitive structures would likely need to be supported deep foundations, such as driven piles or drilled piers. The erosion control measures needed during the site development will depend heavily on the weather conditions that are encountered during the earthwork process. All curbs and gutters GEOTECH CONSULTANTS, INC. East Marginal Way PropertilikLC December 26, 2007 • JN 07077 Page 5 around the edges of the site should be left in place to avoid surface water from entering the site. In the past, downstream catch basins would be protected with premanufactured silt "socks ". However, intense rainstorms in recent winters have caused many of these types of "socks" to fail or fill with debris, which blocked the flow of water into the catch basins. Thus use of silt "socks" should be reviewed prior to their use. Where necessary, rocked construction access roads should be extended into the site to reduce the amount of mud carried off the property by trucks and equipment. Temporary soil stockpiles should be covered with plastic during wet weather. We recommend including this report, in its entirety, in the project contract documents. SEISMIC CONSIDERATIONS In accordance with Table 1615.1.1 of the 2003 International Building Code (IBC), the site soil profile within 100 feet of the ground surface is best represented by Soil Profile Type E (Soft Soil Profile). Under the 2006 IBC, the site soil profile would also be E. The soils underlying the water table have a moderate potential for liquefaction in a large earthquake. PAVEMENT AREAS We recommend providing a minimum 2.5 feet of compacted fill beneath the pavement section in all areas. Because the site soils are silty and moisture sensitive, the pavement subgrade must be in a stable, non - yielding condition at the time of paving or placement of additional structural fill. Granular structural fill or geotextile fabric may be needed to stabilize soft, wet, or unstable areas, particularly the pond areas of the site. In order to evaluate pavement subgrade strength, we recommend that a proof roll be completed with a loaded dump truck immediately before paving. In most instances where unstable subgrade conditions are encountered, an additional 12 inches of granular structural fill will stabilize the subgrade, except for very soft areas where additional fill could be required. The subgrade should be evaluated by Geotech Consultants, Inc., after the site is stripped and cut to grade. Recommendations for the compaction of structural fill beneath pavements are given in the section entitled General Earthwork and Structural Fill. The performance of site pavements is directly related to the strength and stability of the underlying subgrade. The pavement section lightly - loaded traffic and parking areas should consist of 2 inches of asphalt concrete (AC) over 4 inches of crushed rock base (CRB) or 3 inches of asphalt- treated base (ATB). This would be appropriate where only passenger vehicle traffic and parking would be expected. We recommend providing main driveways or areas of heavy truck traffic with 4 inches of AC over 6 inches of CRB or 4 inches of ATB. Increased maintenance and more frequent repairs should be expected if thinner pavement sections are used. The pavement section recommendations and guidelines presented in this report are based on our experience in the area and on what has been successful in similar situations. We can provide recommendations based on expected traffic Toads and California Bearing Ratio (CBR) tests, if requested. As with any pavements, some maintenance and repair of limited areas can be expected as the pavement ages. Cracks in the pavement should be sealed as soon as possible after they become evident, in order to reduce the potential for degradation of the subgrade from infiltration of surface water. For the same reason, it is also prudent to seal the surface of the pavement after it has been in use for several years. To provide for a design without the need for any maintenance or repair would be uneconomical. GEOTECH CONSULTANTS, INC. East Marginal Way Properti.LC December 26, 2007 GENERAL EARTHWORK AND STRUCTURAL FILL JN 07077 Page 6 All proposed pavement areas should be stripped of any surface vegetation (of which very little exists), and any deleterious material should be removed, such as trash and mud. The stripped or removed materials should not be mixed with any materials to be used as structural fill, but they could be used in non - structural areas, such as landscape beds. Structural fill is defined as any fill placed where the underlying soil needs to support Toads. All structural fill should be placed in horizontal lifts with the moisture content at, or near, the optimum moisture content of the fill material. The optimum moisture content is that moisture content that results in the greatest compacted dry density of the fill material. The moisture content of fill is very important and must be closely controlled during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type selected, the compaction equipment used, and the number of passes made to compact the lift. The loose -lift thickness should not exceed 12 inches. We recommend observation of fill quality, methods of placement, and compaction testing as the fill is being placed. If a given lift of fill is not compacted to specifications, it should be recompacted to specifications before another lift is placed. This eliminates the need to remove the fill to achieve the required compaction. The following table presents recommended relative compactions for structural fill: Location of Fill Placement Beneath slabs or walkwa s Beneath pavements Minimum Relative Compaction 95% 95% for upper 12 inches of subgrade; 90% below that level Where: Minimum Relative Compaction is the ratio, expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D 1557-78 (Modified Proctor). Structural fill that will be placed in wet weather should consist of a coarse, granular soil with a silt or clay content of no more than 5 percent. The percentage of particles passing the No. 200 sieve should be measured from that portion of soil passing the three - quarter -inch sieve. The geotechnical engineer should be allowed to review prospective structural fill materials before their use at the site. LIMITATIONS The conclusions and recommendations contained in this report are based on site conditions as they existed at the times of our explorations and assume that the soil and groundwater conditions encountered in the explorations 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 GEOTECH CONSULTANTS, INC. East Marginal Way Propertii.LC December 26, 2007 • JN 07077 Page 7 commonly encountered on construction sites, and particularly at sites underlain by old fill and the Duwamish River alluvium. Subsurface conditions will likely vary between exploration locations. Such unexpected conditions frequently require making additional expenditures to attain a properly constructed project. It is recommended that the owner consider providing a contingency fund to accommodate such potential extra costs and risks. This is a standard recommendation for all projects. This report has been prepared for the exclusive use of East Marginal Way Properties, LLC, and its representatives, for specific application to this project and site. Our conclusions and recommendations are professional opinions derived in accordance with our understanding of 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 design. We recommend including this report, in its entirety, in the project contract documents so the contractor may be aware of our findings. ADDITIONAL SERVICES Geotech Consultants, Inc. should be retained to provide geotechnical consultation, testing, and observation services during site earthwork. This is to confirm that subsurface conditions are consistent with those indicated by our exploration, to evaluate whether earthwork activities comply with the general intent of the recommendations presented in this report, and to provide suggestions for design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. However, our work would not include the supervision or direction of the actual work of the contractor and its employees or agents. Also, job and site safety, and dimensional measurements will be the responsibility of the contractor.
