We have reviewed the proposed project and the only concerns that we have are with the landscaping details. The Segale levee is part of the Federally authorized flood control project that was mostly constructed by the Seattle District Corps of Engineers and turned over to 'the City of Tukwila on May 15, 1992, following a joint final inspection. The proposal to place plantings in the levee prism as shown on drawing dated 3/18/99, sheet Li of 1, is not acceptable. No plantings other than sod will be permitted on the levee prism. The issue of oversteepened levee slopes raised by King County Water and Land Resources Division has been discussed with the former Study Manager for the section 205 project and with members of Emergency Management Branch. The consensus is that because this work involved only raising the top of the levee a maximum of about 1.5 feet, it would have been prohibitively expensive to require that the entire riverward slope be re -graded to a more stable 2 horizontal on 1 vertical slope. 06/11/99 11:36 FAX 206 764 3319 EMERG MGMT • If you have any questions please contact Bill C►arrott at (206) 764-3406 or Monte Kaiser at (206) 764-.3712.

A small portion of the building and parking lot lies within the Shoreline Overlay District as the site is adjacent to the Green River, a shoreline of the state. An Army Corps of Engineers Section 205 levee runs along the riverward side of the site. The existing office building will remain in place until construction of the new office building is completed. Proponent: LaPianta Limited Partnership dba Segale Business Park Location: 18500 Southcenter Parkway Date prepared: May 21, 1999 Lead Agency: City of Tukwila, Department of Community Development Challenges to Document: None Other Agencies of Jurisdiction: Department of Ecology • • SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 Recommendation: Determination of Non -Significance (DNS) Existing Environmental Information: • EIS for Segale Business Park, 1974 • Geotechnical Report (12/9/98, 4/15/99) and River Bank Stabilization Study (2/25/99): Geo Engineers, Inc. Comments on SEPA Checklist: Page 5, #5b. Since the time the SEPA checklist was prepared, the Puget Sound Chinook salmon has been listed by the National Marine Fisheries Service as a threatened species. This species is found in the Green River. Summary of Primary Impacts: ' Earth The soils at the proposed building site are silty sands and gravels. The site is flat with an approximately 2 percent grade. Approximately 200 cubic yards of fill will be required to establish the building pad and surrounding driving surfaces. The applicant proposes to use material from the foot excavations for this fill. As part of the shoreline permit process, the applicant submitted a geotechnical analysis showing that the integrity of the levee will not be compromised by the proposed project. The analysis states "(t)he proposed grading operations at the site will be limited to the inland side of the levee and will increase grades in the building area by approximately 3 feet. No grade changes are anticipated within about 60 feet of the levee." The analysis concludes: "In our opinion, placement of the proposed fill will not adversely effect the levee. In addition, based on the information provided and our understanding of existing conditions and past improvements, it is our opinion that the existing levee slopes are presently stable and adequately protected and do not require additional protection. If the site elevations or slopes are changed from those shown on the sections provided and 2 c:\caroUSegale-Ofiice/sepa-rpt • • SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 discussed above, we should be consulted regarding potential effects on the levee." Comments were received from King County Division of Water and Land Resources. The County stated it had "...significant concerns with the oversteepened slope angles along the riverward embankments of the existing levee." The cross section drawings provided by the applicant show the angle of the levee as ranging from 1.32H:1V to 1.37H:1 V. The preferred angle is 2:1. The County believes that levee improvements to this portion of the levee in 1989 were to be constructed at 2H:1V slope, instead of the angels shown on the cross sections. The County's letter, dated May 14, 1999 commenting on the project requests that: • Sufficient site area be preserved to permit establishing an overall slope gradient of 2:1 on the riverward side of the levee should there be an opportunity to reconstruct the levee in the future; and • Sufficient area be preserved to provide for establishment of a 15 -foot wide levee maintenance access roadway along the top crest of the levee slope. Based on the information presented by the applicant and a review by Public Works staff it appears that the stability of the levee is not an issue for this project and that sufficient area exists currently to access the levee for maintenance. Building, parking lot, driveways and sidewalks will cover approximately 64% of the site. Filter media will be used at all existing catch basins, as required by the King County Surface Water Design Manual, to control storm water siltation prior to discharge into existing drainage structures. New catch basins will be installed as a requirement of the construction. Air Normal emissions and dust associated with use of construction equipment will occur during construction of the project. After construction, normal exhaust associated with vehicular traffic will occur. Water trucks will be used during construction. All equipment will meet local, state, and federal emission standards. 3 c:\carol/Segale-Office/sepa-rpt SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 • Water • The Green River abuts the site on the south and east sides of the project site. The project is subject to the State Shoreline Management Act since a corner of the building, landscaping, driveways and parking area fall within 200 feet of the shoreline. No fill or dredge material will be placed in or removed fromsurface water, nor will there be any surface water or ground water withdrawals or diversions. The project site does not lie within a 100 -year floodplain. No discharges of waste materials to surface waters will occur. The office/warehouse will be connected to the City of Tukwila's sewage system. Runoff from the parking areas and building roof will be collected in onsite catch basins and flow by gravity to the existing City of Tukwila storm water system. The site is within the P-17 basin. Oil/water separators will be installed on site to minimize water quality impacts from parking areas. On-site detention will be required prior to any discharge into the P-17 basin. Plants A landscaped area in the front of the existing building is in place. Landscaping will be provided at the front of the site and around the proposed new building. A fence exists on the south side of the property. The applicant proposes to retain the fence along with the existing aggregate rock, which forms a 4 -foot border between the parking curbing and the fence. Landscaping will be planted landward of the levee within the River Environment of the Shoreline, as required by the Tukwila Shoreline Overlay District. The King County Water and Land Resources Division provided the following comment on landscaping of the site: • All landscaping plantings should be consistent with cross section dimensions and construction details and policies set forth in Corps of Engineers' Publication EM 1110-2-301, dated February 28, 1999. In a meeting held on April 16, 1999, on a related project (Segale Building 981, warehouse with associated office and maintenance facilities) the COE stated that grass should be planted on the riverward side of the levee and that at some future time, willows or other trees would be planted on the riverward side, should there be a need to reconstruct the levee. Currently, no room exists for a landscape bench on the riverward side of the levee. The COE expressed concerns about the type of tree proposed for the landscape area at the landward toe of the levee; as a result, the tree type has been revised from a cedar to a 4 c:\carol/Segale-Office/sepa-rpt • • SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 Honey Locust tree. Native grass will be planted as ground cover. This type of tree has been approved by the COE. Animals The SEPA Checklist notes that songbirds, ducks, crows and Canadian geese have been observed on or near the site. The site is located along the Pacific Flyway migration route. The only mammals observed on the site have been rodents. While the Checklist states that no fish have been observed, the National Marine Fisheries Service has recently listed the Puget Sound Chinook salmon as a threatened species. This species is known to inhabit the Green River. The King County Water and Land Resources Division provided the following comment: • To the extent that construction, excavation, and/or landscape plantings may be proposed within the existing River Protection Easement for the levee, it would appear the project proposal is clearly subject to the provisions of the federal Endangered Species Act. Federal agencies are required to consult for any action that "will likely "affect" a listed species. Currently, there are no local, State or Federal regulations that require revisions to this project related to the ESA. Energy/Natural Resources _ Electricity and natural gas will be used in the building for heating and other uses normal for offices. Diesel fuel will be used in construction equipment during construction. The project will not affect the potential use of solar energy by adjacent properties. The building will be designed to meet the Washington State Energy Code to save energy in heating and cooling the structure. Environmental Health No special emergency services will be required as a result of the proposed project. Noise is generated by traffic along the street in front of the site and the close proximity of an asphalt plant to the north. Construction noise will occur during regular hours of 7:00 a.m. to 5:00 p.m. Noise from vehicles once the building is open for business, approximately 8:00 a.m. to 6:00 p.m. All equipment will be operated with required local, state, and federal noise suppression devices. 5 c:\carol/Segale-Office/sepa-rpt SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 • • Land/Shoreline Uses The site is currently developed with a 3,450 square foot, one story office building. This building will remain in operation until construction is completed on the new building and then it will be demolished. The new building will be two story and contain 16,800 square feet. To the north is anasphalt plant, and on the west is Southcenter Parkway and across the street low density residential. The Green River and a COE Section 205 levee border the site on the east. A manufacturing company's office and warehouse borders the site on the south. The site is designated Heavy Industrial on the Comprehensive Plan Land Use Map and is zoned Heavy Industrial. The proposed use is consistent with the Comprehensive Plan and Zoning designation. The Shoreline Master Program designation is Urban and the proposal must obtain a Shoreline Substantial Development permit. Approximately 20-40 people will work on the site when the project is constructed. Housing No housing exists on the site. Aesthetics The type of construction proposed for the building is stucco.. The project is subject to design review and will be considered by the Tukwila Board of Architectural Review. The maximum height of the building in the shoreline area is 35 feet. The building is proposed to be 29 feet. Light/Glare The building will have exterior lighting, which will occur from dusk to dawn. No glare from the building is anticipated. Recreation A pedestrian/bike trail system exists on the opposite side of the Green River along with a City of Kent park. As part of the project, an outside picnic area will be provided for employees of the office building. 6 c:\carol/Segale-Office/sepa-rpt SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 Historic/Cultural Preservation There are no places or objects listed on or proposed for national state or local preservation registers. Transportation A Traffic Impact Analysis was provided for review. Direct access to the site is via Southcenter Parkway. Transit service is available on South 180th Street, approximately one-half mile north of the project site. Bicycle and vehicle parking will be provided on site. Office uses in the Heavy Industrial zone are required to provide 3 parking stalls for each 1000 square feet of useable office area. For a 16,800 square foot building up to 50 parking stalls will be required. The site plan indicates 59 parking stalls are provided. Two bicycle parking spaces will be required. The traffic analysis identifies the number of trips that will be generated by the additional area being constructed in the office building and distributes the trips on the adjacent roadway system. The number of new trips that will be generated is 148, with a total of 21 AM peak trips and 20 PM peak trips being generated. There are several capital road projects in the Southcenter area identified by the City. A proportionate share of the costs for these projects will apply to this development. The traffic analysis estimates that a total of $4,748 will be paid in concurrency fees as the project's share in the cost of improvements to Strander Boulevard/Andover Park East, S. 180th and West Valley Highway, and Strander Blvd. and West Valley Highway. The exact amount will be determined before the issuance of the building permit. Southcenter Parkway/57th Street, south of South 180th Street is a two-lane road. Based on Traffic Concurrency Standards (TMC 9.48), prior to issuance of the building permit, the applicant will dedicate ten (10) feet of additional right of way for future road widening on Southcenter Parkway/57th Street. Curb, gutter and sidewalk will be installed at a later date as part of a larger road improvement project, as required by the Sidewalk Construction Standards (TMC 11.64) and the Infrastructure Design and Construction Standards manual. The applicant will pay a proportionate share of the cost to install these improvements. 7 c:\carol/Segale-Office/sepa-rpt SEPA Review E99-0003 Segale Office Building #982 June 9, 1999 • • Utilities Public Services The development of this site as an office building will gene:rate an increased need for public services such as police and fire. The Fire Department has noted that the building will need to be sprinlded and that a hydrant is required within 150 feet of the office building with no portion of the structure further than 300 feet from a hydrant. Utilities currently available at the site include electric, natural gas, water, refuse service, telephone, storm water and sanitary sewer. The Minider sanitary sewer lift station, to which sewage would flow from this project, is scheduled for an upgrade in the near future. At the time of the issuance of the building permit, this project will be required to contribute its fair share towards the cost of this upgrade, as required by the Utility Concurrency Standards (TMC 14.36). No other additional utilities are anticipated to be needed as a result of the building construction.

Comments on SEPA Checklist: Page 5, #5b. Since the time the SEPA checklist was prepared, the Puget Sound Chinook salmon has been listed by the National Marine Fisheries Service as a threatened species. This species is found in the Green River. Summary of Primary Impacts: Earth The soils at the proposed building site are silty sands and gravels. The site is flat with an approximately 2 percent grade. Approximately 200 cubic yards of fill will be required to establish the building pad and surrounding driving surfaces. The applicant proposes to use material from the foot excavations for this fill. As part of the shoreline permit process, the applicant submitted a geotechnical analysis showing that the integrity of the levee will not be compromised by the proposed project. The analysis states "(t)he proposed grading operations at the site will be limited to the inland side of the levee and will increase grades in the building area by approximately 3 feet. No grade changes are anticipated within about 60 feet of the levee." The analysis concludes: "In our opinion, placement of the proposed fill will not adversely effect the levee. In addition, based on the information provided and our understanding of existing conditions and past improvements, it is our opinion that the existing levee slopes are presently stable and adequately protected and do not require additional protection. If the site elevations or slopes are changed from those shown on the sections provided and 2 c:\carol/Segale-Office/sepa-rpt 0 SEPA Review - E99-0003 Segale Office Building #982 June 9, 1999 • discussed above, we should be consulted regarding potential effects on the levee." Comments were received from King County Division of Water and Land Resources. The County stated it had "...significant concerns with the oversteepened slope angles along the riverward embankments of the existing levee." The cross section drawings provided by the applicant show the angle of the levee as ranging from 1.32H:1V to 1.37H:1 V. The preferred angle is 2:1. The County believes that levee improvements to this portion of the levee in 1989 were to be constructed at 2H:1V slope, instead of the angels shown on the cross sections. The County's letter, dated May 14, 1999 commenting on the project requests that: • Sufficient site area be preserved to permit establishing an overall slope gradient of 2:1 on the riverward side of the levee should there be an opportunity to reconstruct the levee in the future; and • Sufficient area be preserved to provide for establishment of a 15 -foot wide levee maintenance access roadway along the top crest of the levee slope. Based on the information presented by the applicant and a review by Public Works staff it appears that the stability of the levee is not an issue for this project and that sufficient area exists currently to access the levee for maintenance. Building, parking lot, driveways and sidewalks will cover approximately 64% of the site. Filter media will be used at all existing catch basins, as required by the King County Surface Water Design Manual, to control storm water siltation prior to discharge into existing drainage structures. New catch basins will be installed as a requirement of the construction. Air Normal emissions and dust associated with use of construction equipment will occur during construction of the project. After construction, normal exhaust associated with vehicular traffic will occur. Water trucks will be used during construction. All equipment will meet local, state, and federal emission standards. 3 c:\carol/Segale-Office/sepa-rpt SEPA Review - E99-0003 S Segale Office Building #982 June 9, 1999 Water The Green River abuts the site on the south and east sides of the project site. The project is subject to the State Shoreline Management Act since a corner of the building, landscaping, driveways and parking area fall within 200 feet of the shoreline. No fill or dredge material will be placed in or removed from surface water, nor will there be any surface water or ground water withdrawals or diversions. The project site does not lie within a 100 -year floodplain. No discharges of waste materials to surface waters will occur. The office/warehouse will be connected to the City of Tukwila's sewage system.

Segale Business Park Tukwila File Nos. L99-0020: L99-0019: E99-0009 Dear Mr. Lancaster: Thank you for the opportunity to review the subject application for construction of a 16,800 square foot, two story office building at 18500 Southcenter Parkway within the Segale Business Park in the City of Tukwila. King County has a significant interest in this application, as the proposed site development plan may potentially affect the county's maintenance and repair responsibilities for the existing flood containment levee along the Green River at the project site. King County is party to a June 30, 1992 Green River Basin Program Interlocal Agreement with the City of Tukwila and other Green River Valley Cities in which King County has agreed to maintain levees, riverbanks, and revetments within the Green River Flood Control Zone Dis- trict (GRFCZD). To this end, King County in 1991 assigned its River Protection Easement rights to the City of Tukwila asa tenant in common, in order to facilitate Tukwila's completion of the federally authorized Lower Green River Flood Control Project with the Corps of Engi- neers. This easement encumbers portions of the project site within thirty feet of the top -of - bank along the riverward edge of the existing levee crest. This easement width was established in 1964, and is not adequate for today's continuing flood protection needs. The applicant is clearly relying on this flood protection for the new building which is the sub- ject of this application. Equally important to the project is the County's continuing -mainte- nance and repair of this levee segment to provide 100 -year flood containment to the applicant's property. This responsibility is part of the County's agreement with the City of Tukwila. How ever, performance of this responsibility is dependent on a sufficient easement area within which to accomplish these maintenance services. The connection to the applicant's proposal is that these flood repair and maintenance services are essential for the viability of the building pro- posal. Therefore, requiring sufficient easement area needed to accomplish these services we believe, is a reasonable requirement for issuance of the permits involved, including slope stability provisions of the City of Tukwila's Flood Zone Control Permit. Steve Lancaster May 14, 1999 Page 2 RECEIVED MAY 1 91999 COMMUNITY DEVELOPMENT King County has significant concerns with the oversteepened slope angles along the riverward embankments of the existing levee. These concerns are pertinent to the present application for three reasons: 1. First, the present levee slopes are shown in theapplicant's cross section drawings of the site at severely oversteepened angles of repose, ranging from approximately 1.32 horizontal feet per vertical foot to about 1.37 horizontal feet per vertical foot (1.32H:1V-1.37H:1V). These slope angles are far in excess of those required to meet minimum federal standards for levee slope stability. .. 2. Second, engineering drawings prepared by the Corps of Engineers in April 1989 for levee raising performed in this reach by the subject landowner on behalf of the City of Tukwila as local sponsor to the federal Section 205 Lower Green River Flood Control Project clearly show this work was to be accomplished at overall slope angles .of 2H:1 V. The present character of these levee slopes clearly shows the earlier construction work has not achieved this engineering requirement: 3. Slope stability analyses performed by geotechnical consultants on behalf of King County at two sites immediately downstream of this project location, at a site immediately across the river from this levee, and at three other sites within the lower Green River levee system yield remarkably consistent results with respect to minimum stability requirements needed for levees built on nearly identical soils. In order to achieve the minimum factors of safety required for federal levees, slopes should be placed at from 2H:1 V to 2.5H: 1 V gradients. These findings are again consistent with the 1989 Corps of Engineers 211: IV design draw- ings for this reach, and clearly show the existing slope configuration is substantially substandard. I therefore respectfully request the City of Tukwila's careful consideration of the site plan --- review to include reasonably prudent measures assuring the future integrity and stability of the levee system within the project site. Specific measures necessary to this end are requested as follows: 1. Sufficient site area needs to be preserved free from excavation, grading, landscape plant- ings, and other site improvements to facilitate King County's continuing abilities to accom- plish future levee repairs designed at stable angles of repose for the affected levee slopes along the riverbank. Based on discussions with the property owner to date, no independent analyses of riverbank stability have been performed. King County has contracted for geo- technical consultant studies utilizing soils information provided by the applicant to address this concern. Results of these analyses should be forthcoming with detailed recommenda- tions within the next few weeks. Relying on the consistent findings developed by these same consultants for "next door" portions of the levee system within the Segale Business Park, and also for levee reaches immediately across the river from the project site, it is my recommendation this allowance be predicated on establishing an overall slope gradient of at least 2H:1V, or two horizontal feet to each vertical foot of levee slope elevation above the river bed. 2. Sufficient site area needs be preserved free from site grading, site improvements, and land- scape plantings to provide for establishment of a 15 -foot -wide levee maintenance access Steve Lancaster - May 14, 1999 Page 3 RECEIVED MAY 1 9 1999 COMMUNITY DEVELOPMENT roadway along the top crest of the levee slope, consistent with a top -of -bank location predi- cated on stable slope angles determined pursuant to (1), above. All landscape plantings should be consistent with cross section dimensions and construction details and policiesset forthinCorps of Engineers' Publication EM 1110-2-301, dated February 28, 1999. This is especially important with regard to King County's continuing ability to maintain the levee system in accordance with applicable regulatory standards affecting levees. See also (4), below. 4. It would appear the project proposal is subject to the provisions of the federal Endangered Species Act(ESA) with respect to recent listing of Puget Sound Chinook salmon as a threatened species. The City of Tukwila should consider if site review is consistent with the City's recent submittals concerning programmatic certification under the ESA's required 4(d) Rule. Similarly, the City may need to request that theCorpsconsult with the National Marine Fisheries Service (NMFS) to ensure compliance with requirements estab- lished in Section 7 of the ESA. Based on review of the site plans and cross section drawings submitted to date, it is my request that the City carefully consider our recommendations in the project review and approval proc- ess. At an absolute minimum, it appears that an additional fifteen feet of site area along the river frontage will need to be dedicated as an easement for the purposes of providing for ade- quate levee stability. This may also address both site level and reach level impacts related to ESA concerns with levees as they potentially affect the listed species. Such measures are reasonably necessary as conditions of approval for the permits required by the subject project. Thank you for your consideration of these comments.

Coverage Standards requires 90% live ground coverage within 3 years and 40% tree coverage within 10 years. All shrubs and groundcovers are sized and planted to attain a continuous cover of living plants per standard landscape practice. Most groundcovers are not spaced greater than 2' triangular spacing. If these plants grow 3" per year, then full coverage would occur within 3 years. The shrubs will grow approximately 6" per year and should be touching within 3 years. The ash trees are planted with an 8-10' wide canopy. These trees will grow 2-3 feet spread per year. The hornbeams are approximately 6' width at planting. Their mature width is approximately 16'. Within 10 years the selected trees will reach mature canopy, more than 40% coverage. At the river dike the coniferous trees are planted at approximately 30' on center. The selected varieties stay full to the ground and do not spread in canopy, as do deciduous trees. The trees specified are installed at 6' width, and will grow in width at the rate of 1' to 18" per year. Within 10 years the coniferous trees at the river will have a spread of 16'. The coniferous trees to the west of the building are 10° caliper and have a 20' canopy. These trees will not grow much more in canopy width, perhaps 10% additional width.

The proposed new office is anticipated to have approximately 16,800 square -feet of floor space on two floors and is to be located next to an existing office building. Ground level finish floor elevation is anticipated to be about 31 feet. The Green River passes south and east of the site. We understand that there is a concern that site grading associated with the new office may adversely effect the Green River levee. A Site Plan showing the proposed office footprint and sections which show existing and proposed site grades along the levee is attached. The plan and sections were prepared by Segale Business Park. As indicated on the plan, the 100 -year flood elevation is 30 feet. We have previously prepared a geotechnical engineering report, dated December 9, 1998, for this site. Our report addresses site preparation, earthwork and other geotechnical issues associated with this project. CONCLUSIONS Proposed grading operations at the site will be limited to the inland side of the levee and will increase grades in the building area by approximately 3 feet. Based on our review of the Site Plan and sections 0+00 through 1+50 provided, we understand that no grade changes are anticipated within about 60 feet of the levee.

In addition, based on the information provided and our understanding of existing conditions and past improvements, it is our opinion that the existing levee slopes are presently stable and adequately protected and do not require additional protection. If the site elevations or slopes are changed from those shown on the sections provided and discussed above, we should be consulted regarding potential effects on the levee. 4+P We trust that this letter provides the information you require.

Preparing a written report containing our conclusions and recommendations along with our supporting data. SITE CONDITIONS SURFACE CONDITIONS The proposed new office site is located directly east of an existing office building and south of the existing asphalt batch plant. The site is presently undeveloped except for paved parking east and north of the existing office. We understand that the proposed building area was previously surcharged by stockpiled soil. Existing ground surface elevation in the proposed building footprint is about 28 feet (based on topographic data supplied by Segale Business Park) The height of material stockpiles located north and east of the site ranges from about Elevation 35 to 50 feet. The property boundaries, topographic contours, and proposed building location are shown on the Site Plan, Figure 2. SUBSURFACE EXPLORATIONS Subsurface explorations were conducted by Geoengineers Inc. on November 19, 1998 at the approximate locations indicated on the Site Plan, Figure 2. Exploratory test pits were advanced using a rubber -tired backhoe and operator supplied by Segale Business Park. Representative bulk samples were obtained from the test pits. The explorations were located in the field by our personnel by taping or pacing from relevant site features. Test pit locations should be considered approximate. Our representative collected samples of the soils encountered, observed ground water conditions and maintained a detailed log of the explorations. Soils were classified in general accordance with Figure 3. Existing ground surface elevations shown on the logs were estimated from topographic data supplied by Segale Business Park. Summary test pit logs are presented as Figure 4. Laboratory testing consisting of moisture content determination of selected bulk samples. Moisture results are presented on the corresponding logs. SUBSURFACE CONDITIONS Subsurface soils encountered in the explorations generally consist densely compacted sand and gravel fill overlying alluvial deposits consisting of interbedded fine to medium sand, sandy silt and silt in a medium dense to dense or stiff condition. Fill soil consisting of sand and gravel with varying amounts of silt and occasional cobbles was encountered to a depth of 3.25 feet and 3 feet below existing ground surface (approximately Elevation 28 feet) in test pits 1 and 2 respectively. The fill was described as very dense to dense and moist. In test pit 2, an approximately 1 -foot thickness of waste asphalt was encountered at the ground surface. G e o E n g i n e e r s File No. 0291-012-00 Segale Business Par December 9, 1998 k Page 3 • Below the fill, test pit 1 encountered medium dense to dense, moist, fine to medium sand with silt to a depth of about 8 feet. Below the sand, moist, stiff silt with trace fine sand and organic material was encountered to the 10 -foot depth explored. Below the waste asphalt and sand and gravel fill, test pit 2 encountered dense, moist fine sand with silt to a depth of about 10 feet. Below the sand, stiff, moist silt with fine sand was encountered to the bottom of the test pit at 12 feet. No ground water was encountered in the test pits. No caving was noted. Summary logs of the test pits are presented in Figure 4. Deeper explorations from nearby sites indicate that the silt encountered at the bottom of test pits 1 and 2 is underlain by medium dense to dense silty sand and sand. These explorations also indicate that relatively shallow ground water (on the order of 10 feet below ground surface or less) can be expected in the area. CONCLUSIONS AND RECOMMENDATIONS GENERAL Based on our site explorations and observations, it is our opinion that the site is suitable for the proposed development. We recommend that the proposed office building be supported on shallow spread and strip footings founded on densely compacted fill overlying the native silty sand and sand with silt. In our opinion, existing site soils are sufficiently dense and the presence of previously stockpiled soil in the building area precludes the need to preload the site to control post -construction settlement. Pertinent conclusions and recommendations regarding site work and design and construction of the proposed office building are presented below. EARTHWORK ' We expect that the any required site grading can be accomplished with conventional earthmoving equipment. The native site soils below the fill have significant silt contents and are moisture sensitive. These materials will be difficult to operate on or compact during wet weather. Operation of heavy equipment at the site under wet conditions can be expected to result in considerable disturbance to the exposed native subgrade. We recommend that earthwork be undertaken during periods of dry weather, if feasible, to minimize grading costs. Based on our explorations, we estimate that a minimum amount of site preparation will be required and will be limited to removal of existing asphalt parking areas and relocating nearby stockpiles. Structural fill, where required, should be compacted to the densities indicated in the "Structural Fill" section of this report. In our opinion, structural fill can be placed directly over existing dense fill. STRUCTURAL FILL All fill beneath structures or pavements, and within utility trenches or other excavations beneath structures or pavements should be placed as structural fill. Structural fill material should be free of debris, organic contaminants, and rock fragments larger than about 6 inches. GeoEngineers File No. 0291-012-00 Segale Business Pari December 9, 1998 Page 4 • The workability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (material passing the U.S. No. 200 sieve) increases, soil becomes increasingly more sensitive to small changes in moisture content and adequate compaction becomes more difficult or impossible to achieve. If fill material is imported to the site for wet weather construction, we recommend that it be a sand and gravel mixture such as high quality pit run, with less than 5 percent fines. Structural fill should be uniformly compacted in horizontal lifts to at least 95 percent of the maximum dry density (MDD) determined in accordance with ASTM D-1557 (modified Proctor). Pavement subgrade soils and utility trench backfill should be compacted to at least 90 percent of the MDD up to within the upper 2 feet; the upper 2 feet should be compacted to at least 95 percent. The lift thickness used during placement and compaction will depend on the moisture and gradation characteristics of the soil and the type of equipment being used. If necessary, the material should be moisture conditioned to near -optimum moisture content prior to compaction. In our opinion, during dry weather construction, any nonorganic on-site soil may be considered for use as structural fill, provided it meets the criteria described above and can be compacted as recommended. If the material is over optimum moisture content when excavated, it will be necessary to aerate or dry the soil prior to placement as structural fill.. FOUNDATION SUPPORT In our opinion, the proposed office structure be supported on shallow spread footings bearing on a minimum of 2 feet of compacted structural fill. Based on our observations, existing fill at the site is suitable for foundation bearing. In general, footings founded on compacted structural fill prepared as described above may be designed using an allowable soil bearing pressure of 2,500 pounds per square foot (psf) for combined dead and long-term live loads, exclusive of the weight of the footing and any overlying backfill. This value may be increased by one-third when seismic or wind loads are considered. We recommend a minimum width of 18 inches for continuous wall footings and 2 feet for isolated footings. All footing elements should be embedded at least 18 inches below lowest adjacent grade. We recommend that all loose or disturbed soils within the footing excavations be compacted as recommended, if practical, or overexcavated and replaced with compacted structural fill prior to concrete placement. Lateral loads may be resisted by friction on the base of the footing and as passive pressure on the sides of footings, or where applicable, stem walls. We recommend using a coefficient of friction of 0.5 to calculate friction between the concrete and densely compacted native soil or structural fill. Passive pressure may be determined using an equivalent fluid weight of 400 pcf. This assumes that structural fill is placed against the sides of the footings. An appropriate safety factor should be applied to these values. GeoEngineers File No. 0291-012-00 Segale Business Parke December 9, 1998 Page 5 • We estimate that settlements of footings designed and constructed as recommended will be less than 1 inch with differential settlements measured along 25 feet of continuous wall footings or between comparably loaded isolated footings of 1/2 inch or less. Most of the settlements should occur essentially as loads are being applied. However, loose or soft soil below the footings or disturbance of the foundation subgrade during construction could result in larger settlements than predicted. SLAB -ON -GRADE SUPPORT In our opinion, estimated slab -on -grade floor areal loads of up to 250 psf could be supported on a minimum of 2 feet of compacted structural fill as previously recommended. We recommend that slabs -on -grade be directly underlain by a 4 to 6 -inch thickness of granular base course material consisting of crushed rock or well graded sand and gravel which contains less than 3 percent fines based on the minus 3/4 -inch fraction. If dry slabs are required (e.g., where adhesives are used to anchor carpet or tile to the slab), a waterproof liner, at least 6 mils thick, should be placed as a vapor barrier below the slab. A 2 -inch thickness of clean sand can be placed over the vapor barrier to protect the liner and serve as a leveling course. We estimate that settlement of a concrete slab supported as recommended above will be less than 1/2 inch over 50 feet. PAVEMENT DESIGN CONSIDERATIONS We recommend that pavement sections be supported on a minimum of 2 feet of structural fill extending to the underlying native sand and silt. Structural fill should be placed and compacted as recommended previously. In addition, the prepared subgrade should be thoroughly proofrolled prior to placing base course to identify any soft or loose soils. If soft or loose soils are encountered, they should be removed and replaced with compacted structural fill. We recommend the pavement in areas to be used exclusively for light vehicle traffic consist of 2 inches of Class B asphalt concrete over 4 inches of crushed surfacing base course. For pavement in more heavily traveled areas or with significant truck traffic, we recommend providing 3 inches of asphalt concrete over 6 inches of crushed surfacing base course. The base course should be compacted to at least 95 percent of the maximum dry density (ASTM D- 1577). Crushed rock base course should comply with Washington State Department of Transportation (WSDOT) Standard specifications for Road, Bridge and Municipal Construction Section 9-03.9(3). These pavement sections may not be adequate for heavy construction traffic conditions such as imposed by concrete transit mixers, dump trucks or crane loads. Additional pavement thickness may be necessary to prevent pavement damage during construction, and/or repair of damaged pavements should be anticipated. G e o E n g i n e e r s File No. 0291-012-00 Segale Business Park. December 9, 1998 Page 6 Asphalt pavement surfacing should meet the specifications for Class B asphaltic concrete, as described in WSDOT Section 9-03.8. We recommend that it be compacted to a minimum of 92 percent of the theoretical maximum, as described by WSDOT Test Method 705. DRAINAGE CONSIDERATIONS We recommend that all ground surfaces, sidewalks and pavement surfaces be sloped so that surface drainage flows away from the building. We recommend that all roof drains be collected in tightlines for diversion into the storm drain system. LIMITATIONS We have prepared this report for Segale Business Park and their agents for use in design and construction of the various components of this project. The conclusions and recommendations in this report should be applied in their entirety. The data and report may be provided to prospective contractors for bidding or estimating purposes; but our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. If there are any changes in the grades, location, configuration or type of construction planned, the conclusions and recommendations presented in this report might not be fully applicable. If changes are made, we should be retained to review our conclusions and recommendations and to provide written modification or verification, as appropriate. When the design is fmalized, we recommend that GeoEngineers be engaged to review those portions of the plans and specifications that relate to geotechnical considerations to check that our recommendations have been interpreted and implemented as intended. 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. The subsurface conditions are expected to vary across the site. A contingency for unanticipated conditions should be included in the construction budget and schedule. Sufficient monitoring, testing and consultation should be provided by GeoEngineers during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should be conditions revealed during the work differ from those anticipated, and to evaluate whether earthwork and foundation installation activities comply with contract plans and specifications.
