Currently the site is undeveloped. It is bordered on the south side by SW 7th Street and on the north, west and east sides by existing railroad tracks. (Note: the track are situated on a 40 foot wide rail easement the center line of which is coincident with the property line. Thus the easement extends 20 feet onto the subject property.) Current vegetation consists of low grass and shrubs and several cottonwood trees. There are no structures on the site and no notable special features other than the existence of the railroad tracks. The properties to the west and north are improved with industrial buildings. The site immediately adjacent to the east is currently unimproved. Development of the subject site will not obstruct the views from the adjacent sites. The proposed development is currently being referred to as Lot I, Washington Technical Center. A new name will most likely be selected for marketing purposes some time in the near future. The proposed development consists of a 34,585 square foot office industrial building. The appearance of the building would be similar to the buildings located in the Gateway North development at I I6th and Interurban Ave. Approximately 90 parking stalls will be provided. The building will have inside height of 22 to 24 feet to the lowest roof member and thus will be capable of accommodating mezzanine offices although none are planned under the current application. The building is being developed on a speculative basis with no specific user identified at the current time. It is anticipated that the usage of the building will be for light manufacturing or distribution type tenants who in general would require a ratio of office improvements to total floor area of approximately 25 percent. The project has a provision for dock high loading but is not intended to support extensive trucking operations. Access to the site will be provided by two curb cuts onto SW 7th street. Approximately 90 parking stalls will be provided and the ratio of impervious surface (building and paved surfaces) to the overall site is anticipated to be approximately 80 percent. The legal description for the project is: Lot 1, the plat of Washington Technical Center, according to the plat thereof recorded in Volume 122 of Plats, pages 98 through 102, inclusive, Records of King County, Washington. 1997 CITY of gENT0NNiNG r, lick CITY OF RENTON DEVELOPMENT SERVICES DIVISION MASTER APPLICATION PROPERTY OWNER(S) PROJECT INFORMATION Note:',tf there is more than one legal owner, please attach an additional notarized Master Application for each owner.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this.checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or"does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS.(part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal,," "proposer," and "affected geographic area," respectively. 6,j' , yrrop p�ANIVING p�"N7ph Fmironmental Checklist A.

Report E-884 dated April 22, 1981 I Earth Consultants, Inc . Report E-884-1 dated December 22, 1981 Gentlemen: i I We are pleased to submit herewith our report entitled "Geotech- ! nical Engineering Study, 9.4 Acre Site, Washington Technical Center, Renton, Washington." This report presents the results of our field exploration, laboratory tests, and engineering analysis . The purpose and scope of our . study was outlined in our proposal dated June 25, 1985. Previous studies were conducted on and near the subject site by Earth Consultants, Inc. Results of these studies were reported in the referenced reports. j Our study indicates that in the proposed building area there exists soft, compressible soils near the ground surface. To re- i duce potential foundation settlement, it is recommended th4t the conventional spread or continuous footings be founded on two feet of structural fill. The structural fill distributes the ' loads to the underlying soil, thus reducing the effective bearing pres- sures . Buildings constructed after primary settlements induced by the structural fill have been realized may experience post- construction settlements on the order of one to two inches . Differential settlements between lightly loaded and heavily loaded columns may be approximately one-half of these values . If these settlements cannot be tolerated, we recommend that the building area be surcharged. If these settlements can be tolerated, the fills needed to prepare the site for construction should be allowed to remain in-place until the settlements have stabilized. This should take about three to five weeks. The following sections of this report describe our study and contain recommenda- tions regarding foundation design criteria, earthwork considerations, and site drainage . 1805 - 136th Place N.E..

No other warranty, expressed or implied, is made. We recommend that this report, in its entirety, be included in the project contract documents for the information of the contractor. PROJECT DESCRIPTION At the time our study was performed, the site and proposed building locations were as shown schematically on the Boring and Probe Location Plan, Plate 2. Based on our discussions with your architect, we understand that it is planned to construct four, single-story, concrete tilt-up office buildings with design floor loads of one hundred fifty (150 ) pounds per square foot (psf) . Building No. 4 is proposed on Lot No. 3 and Building Numbers 5, 6 and 7 are proposed on Lot No. 4. We understand that maximum column loads are approximately 40 kips . It is anticipated that approximately three feet of structural fill will be required to achieve final proposed grades . If any of the above design criteria change, we should be consulted to review the recommendations contained in this report. In any case, it is recommended that Earth Consultants , Inc. provide a general review of the final design. SITE CONDITIONS - Surface The proposed 9.4 acre building site is located on Powell Avenue SW and just north of SW 7th Street in Renton, Washington. The property is adjacent to an existing structure and railroad tracks on the south, to Powell Avenue SW on the west, and to vacant property on the north and the east. The site is relatively flat except for an existing fill approximately five feet high on the western portion of Lot No. 3 . At the time of our exploration, the site was covered with tall grass and brush with trees on the northern portion of the property. Surficial soils were generally dry and stable. Subsurface The site was explored by drilling two test borings and advancing three Dutch Cone probes. Other locations were explored -during our referenced studies on or near the subject site. Exploration locations are shown on Plate 2 . Please, refer to the Earth Consultants, Inc. Holvick deRegt Koering E-884-11 r August 21 , 1985 Page 3 boring logs, Plates 4 and 5, and the Dutch Cone logs, Plates 7 through 9, for a detailed description of the conditions encountered at each location explored. A description of the field exploration methods and laboratory testing program is included in this report following the Discussion and Recommendations section. The following is a generalized description of the subsurface conditions encountered. Our borings and probes generally encountered soft, moderately compressible clayey silts underlain by medium dense to dense gravels . Boring B-101 and Probe P-103 encountered approximately twenty (20) feet of soft, compressible soils beneath the existing ground surface. Approximately thirteen (13 ) feet of soft soils were encountered in Boring B-102. Probes P-101 and P-102 encountered approximately ten feet (10 ) of soft, compressible soils. Clayey silts encountered generally exhibit low plasticity with Liquid Limits ranging from 35 to 40 and Plastic Indexes ranging from 7 to 9. A moderately plastic clayey silt was encountered in Boring B-101 . This silt has a Liquid Limit of 50 and a Plastic Index of 17 . Sandy gravels were generally encountered beneath the compressible clayey silt stratum. Gravels are medium dense and grade to dense with depth. Gravels were encountered to the maximum depth explored at each location. Groundwater The groundwater levels observed while drilling are shown on the boring logs. Since the groundwater levels did not have time to stabilize, slotted pipe standpipes were installed in Borings B-101 and B-102. Readings taken eleven ( 11) days after the completion of the borings are also shown on the boring logs. Groundwater was encountered at eight to ten feet beneath the existing grade . The groundwater seepage level is not static, thus one may expect fluctuations in the level depending on the amount of rainfall, surface water runoff, and other factors. Generally the water level is higher in the wetter winter months. DISCUSSION AND RECOMMENDATIONS General As previously described, the ground surface is underlain by soft, compressible clayey silts above gravels. The thickness of the compressible soil stratum encountered varies from approximately ten feet at the locations of Probes P-101 and P-102 (Buildings 5 and 6) to approximately twenty (20 ) feet at the locations of Boring B-101 and Probe P-103 (Budlding 4,) . To Earth Consultants, Inc. Holvick deRegt Koering E-884-11 August 21 , 1985 Page 5 Lateral loads due to wind or seismic forces may be resisted by friction between the foundations and the supporting compacted fill subgrade or by passive earth pressure on the foundations . For the latter, the foundations must be backfilled with a compacted fill meeting the requirements of structural fill. A coefficient of friction of 0 .35 may be used between the structural foundation concrete and the supporting subgrade. The passive resistance of well compacted fill may be taken as equal to the pressure of a fluid having a density of three hundred (300 ) pounds per cubic foot (pcf) . We recommend that drains be placed around all perimeter foot- ings. The drains should be constructed with a four inch diameter perforated pipe bedded and covered with free draining gravel. The drains should have a positive gradient towards suitable discharge facilities . The footing drainage system should not be tied into the roof drainage system until the drains are tightlined well away from the building. The footing excavation should be backfilled with granular soil except for the top foot which should be backfilled with a relatively impermeable soil such as silt, clay or topsoil. Alternatively, the surface can be sealed with asphalt or concrete pavements . Slab-on-Grade Floors Slab-on-grade floors may be supported on at least one foot of structural fill. At the time of our exploration, surficial soils were generally dry and stable. If construction is conducted during wet weather, a greater thickness of fill and/or a stabilization fabric may be necessary. The slab should be provided with a minimum of four inches of free draining sand or �g ravel. We also recommend that a vapor barrier such as a 6 mil plastic membrane be placed beneath the slab to reduce water vapor transmission through the slab and the resultant moisture accumulation. Two inches . of sand may be placed over the membrane for protection during construction and to aid in curing of the concrete. Surcharge Procram As indicated earlier in this report, if the anticipated settlements cannot be tolerated, we recommend that the building area be surcharged with a minimum of three feet of fill. This surcharge is in addition to any structural fill materials required to achieve design finish grades . The top of the surcharge fill should extend at least five feet beyond the edges of the proposed building. We estimate that the surcharge fill will need to remain in place approximately three to five weeks to permit primary settlements to be completed, after which, building construction may be started. Earth Consultants. Inc. C Holvick deRegt Koering E-884-11 August 21 , 1985 Page 6 Before placing the surcharge fill, structural fill should be placed, if necessary, to the design finish grade. Depending on site grades , it may be necessary to excavate soil to provide the required thickness of structural fill below footings and slabs. Alternately the footing excavation can be done after removal of the surcharge fill. The surcharge fill does not have to meet any specific require- ments except that it should have a minimum in-place total density of one hundred twenty (120 ) pcf. However, if the surcharge fill is to be later used as fill on another part of the site, we recommend it meet the requirements for structural fill, i.e. , contain no organics and be compactible. Structural fill to be placed in wet weather should contain no more than 5 percent fines passing the No. 200 sieve. The side slopes of the surcharge fill should be inclined no steeper than 1: 1 (Horizontal:Vertical ) . No fill for landscaping purposes should be placed near the building since any additional fill could induce further settlement . Prior to placement of the surcharge fill, we recommend installation of at least three settlement markers per building within the pre-load area. These markers should be protected from disturbance by construction equipment . The markers should be surveyed by Earth Consultants, Inc. personnel or a licensed surveyor during fill and surcharge placement and at intervals of 2, 4 , 8, 16 (and so forth) days after completion of the surcharge fill placement . The initial reading should show the natural ground elevation, and readings taken during surcharge placement should show the surcharge fill thickness . We will evaluate the settlement readings. Once the required settlement has been reached, the surcharge may be removed. The exposed subgrade should be proofrolled, and any loose pockets exposed should be overexcavated and replaced by structural fill . Site Drainace Groundwater was encountered in our borings at depths ranging from eight to ten feet. It is not anticipated that groundwater will be encountered during construction. However, it has been our experience that groundwater levels change significantly due to changes . in rainfall amounts , surface drainage or other factors . If seepage is encountered in the excavation, the water should be drained away from the site by use of drainage ditches, perforated pipe or French drains, or by pumping from sumps interconnected by shallow connector trenches at the bottom of the excavation. The site should be graded so that surface water is directed off the site and away from the tops of slopes . Water should not be allowed to stand in any area where buildings, slabs, or Earth Consultants, Inc. Holvick deRegt Koering E-884-11 August 21 , 1985 Page 7 pavements are to be constructed. During construction, loose surfaces should be sealed at night by compacting the surface soils to reduce the infiltration of rain into the soils . Final site grades should allow for drainage away from the building founda- tions. We suggest that the ground be sloped 3 percent for a distance of at least ten feet away from the buildings except in areas that are to be paved. Pavement Areas All parking and roadway areas may be supported on a minimum of twelve ( 12) inches of structural fill placed in accordance with the Site Preparation section of this report . At the time of our exploration, surficial soils were generally dry and stable. If construction is conducted during wet weather, a greater thickness of structural fill or a stabilization fabric may be needed to stabilize soft, wet or unstable areas. The upper twelve (12) inches of pavement subgrade should be compacted to at least 95 percent of the maximum density. Below this level a compactive effort of 90 percent would be adequate. The pavement section for lightly loaded traffic and parking areas . should consist of two inches of asphalt concrete (AC) over four inches of crushed rock base (CRB ) or three inches of asphalt treated base (ATB ) . Heavier loaded areas would require thicker sections. We will be pleased to assist you in developing appropriate pavement sections or specifications for heavy traffic zones, if, needed. Site Preparation and General Earthwork To maintain the integrity of the surface soils, stripping of the %sod should be avoided where possible. Buildings and pavement areas should be cleared of any surface debris and any other deleterious matter, such as trees , brush, fences, etc. The grass cover should be mowed -and hauled off the site. Fills may be placed directly on the sod cover in areas where fills are at least two feet deep. Structural fill under floor slabs and footings should be placed in horizontal lifts and compacted to a minimum 95 percent of the maximum dry density in accordance with ASTM Test Designa- tion D-1557-70 (Modified Proctor) . The fill materials should be placed at or near the optimum moisture content. Fill under pavements and walks should also be placed in horizontal lifts and compacted to 90 percent of maximum density except for the top twelve (12) inches which should be compacted to 95 percent of maximum density. We understand that imported structural fill will be required for site preparation. Ideally, structural fill 'to !be placed in wet weather should consist of a granular material with a maximum Earth Consultants. Inc. H olvick deRegt Koering E-884-11 August 21 , 1985 Page 8 size of three inches and no more than 5 percent fines passing the No. 200 sieve. During dry weather, any compactible non-organic soil can be used as structural fill. FIELD EXPLORATION AND LABORATORY TESTING Our field exploration was performed on July 11, 1985. Subsurface conditions at the site were explored by drilling two borings and advancing three Dutch Cone probes to a maximum depth of twenty nine (29) feet below the existing grade . The borings were drilled by Drilling Unlimited using a truck-mounted drill rig. Continuous flight, hollow stem augers were used to advance and support the boreholes during sampling. The Dutch Cone is equipped with a friction sleeve which allows the shaft resistance to be measured in addition to the point resistance at the top of the probe . Approximate soil classifications can be inferred - by comparing the point resistance to the friction on the sleeve. A direct correlation is obtained between the point resistance and the bearing capacity of the soil. Soil samples are not obtained from the Dutch Cone probes . The locations of the borings and probes were approximately determined by tape measurements from approximate property corners . Elevations of borings and probes were approximately determined by a hand level from an arbitrary elevation datum. The locations and elevations of the borings and probes should be considered accurate only to the degree implied by the method used. These locations are shown on the Boring and Probe Location Plan, Plate 2. The field exploration was continuously monitored . by a geotechnical engineer from our firm who classified the soils encountered and maintained a log of each boring, obtained representative samples, measured groundwater levels, recorded probe readings and observed pertinent site features . Slotted standpipes were installed in Borings B-101 and B-102 to monitor groundwater levels. All samples were visually classified in accordance with the Unified Soil Classification System which is presented on Plate 3 , Legend. Logs of the borings are presented on Plates 4 and 5. The final logs represent our interpretations of the field logs and the results of the laboratory examination and tests of field samples. The stratification lines on the logs represent the approximate boundary between soil types . In actuality, the transition may be gradual. Logs of the Dutch Cone probes are presented on Plates 7 through 9. The "friction ratio" shown on the plates is the unit resistance of the friction sleeve expressed as a percentage of the unit point resistance . The soil stratigraphy interpreted from the probes indicates fine scale stratification not always obtained from borings . Earth Consultants, Inc. Aolvick deRegt Koering E-884-11 August 21, 1985 Page 9 In each boring, Standard Penetration Tests (SPT) were per- formed at selected intervals in accordance with ASTM Test Designa- tion D-1586. A Shelby tube sampler was used to obtain less disturbed soil samples at selected depths. In addition, the split spoon samples were driven with a one hundred forty ( 140 ) pound hammer falling thirty (30) inches. Shear strengths of undisturbed soils were measured where prac- tical in the field with a torvane. These results are recorded on the boring logs at the appropriate sample depth. Representative soil samples were placed in closed containers and returned to our laboratory for further examination and test- ing. Visual classifications were supplemented by index tests such as Atterberg Limits on representative samples . Moisture determina- tions were performed on all samples. Results of moisture determinations , together with classifications , are shown on the boring logs included in this report. A consolidation test was conducted on a relatively undisturbed representative sample taken with a Shelby tube sampler to evaluate the consolidation characteristics of the site soils. In addition, the time readings were taken at several points of loading to evaluate the time rate of settlement. The results of this test are shown on Plate 6, Consolidation Test Data. LIMITATIONS Our recommendations and conclusions are based on the site materials observed, selective laboratory testing and engineering analyses. The conclusions and recommendations are professional opinions derived in accordance with current standards of practice . No warranty is expressed or implied. The recommendations ' submitted in this report are based upon the data obtained from the borings and probes. Soil and ground- water conditions between exploration locations may vary from those encountered by the borings and proves. The nature and extent of variations between exploration locations may not become evident until construction. If variations then appear, Earth Consultants, Inc. should be allowed to reevaluate the recommendations of this report prior to proceeding with the construction. Additional Services It is recommended that Earth Consultants, Inc. provide a general review of the final design and specifications to verify 1 that the earthwork and foundation recommendations have been properly interpreted and implemented in the design. and in the con- struction specifications . Earth Consultants. Inc. Holvick deRegt Koering E-884-11 August 21, 1985 Page 10 It is also recommended that Earth Consultants , Inc. be retained to provide geotechnical services during construction. This is to observe compliance with the design concepts, specifica- tions or recommendations and to allow design changes in the event ssubsurface conditions differ from those anticipated prior to the start of construction.
