This report presents the results of our field exploration, selective laboratory tests, and engineering analysis, as well as geotechnically related recommendations for the proposed site development in the central portion of the property. The purpose and scope of our study was outlined in our proposal March 10, 1997. Our work on this site covered the entire site bounded by Southwest 19th Street, Lind Avenue, the existing Boeing Office buildings and East Valley road. For the final work product, the site was divided into four separate parcels and corresponding reports. Each report contains the subsurface exploration specific to that portion of the site. Based on the subsurface conditions encountered at the above referenced site, it is our opinion that the proposed buildings may be supported by shallow spread footings bearing on a minimum of two feet of structural fill after completion of a surcharge program, provided that the recommendations contained in this report are incorporated into the construction specifications.

The general location of the site is shown on the Vicinity Map, Plate 1 . The purpose of this study was to explore the subsurface conditions at the site and, based on the conditions encountered, to provide recommendations for site preparation, as well as present geotechnical information for the proposed site development. As requested, we performed a subsurface exploration across the entire site between Southwest 19th Street, Lind Avenue Southwest, East Valley Road and the Boeing Office complex. The engineering analyses and report was separated into four different parcels due to changes in the type of proposed development. The four parcels are the central 5.7 acres, the northeast 2.25 acres, the southeast 2.25 acres and the west 4.5 acres. Borings and test pits were numbered sequentially; however, each report contains only those logs that were documented on the appropriate parcel. This report presents our recommendations and conclusions specifically for the central portion of the property which is proposed to be developed with single-story industrial buildings. Project Description At the time our study was performed, the site, the proposed structures, and exploratory locations were approximately as shown on the Boring and Test Pit Location Plan, Plate 2. Based on information provided by LPN Architects, it is proposed to develop this portion of the site with two office or industrial buildings. We anticipate the buildings will be built at or near the existing grades with up to about two feet of grade modifications. These buildings are anticipated to be one-story, concrete tilt-up construction with slab-on-grade floors. The remainder of this portion of the site is to be paved parking and landscaping areas.

Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 2 Based on our experience with similar structures in the past, we anticipate structural loading to be in the following ranges: • _ Wall footings 3 to 5 kips per lineal foot • Maximum column load - 100 kips • Slab loads - 250 pounds per square foot (psf) If the above design criteria are incorrect or change, we should be notified and allowed to review our recommendations in light of actual design information. In any case, it is recommended that Earth Consultants, Inc. be retained to perform a general review of the final construction design. SITE CONDITIONS Surface The site of the proposed facility is located on Southwest 19th Street in Renton, Washington (see Plate 1, Vicinity Map). The entire rectangular parcel covers about fourteen and one-half acres; however, this report covers only the middle four and one-half acres. The site is bounded by Southwest 19th Street on the south, by vacant portions of the parcel to the west and east, and by a Boeing office complex to the north. At present, the site is vacant with grasses covering the existing surface. The site is generally level with several drainage ditches across the site. In this portion of the site, two building pads have been constructed in the north portion. Subsurface The central portion of the site was explored by excavating five test pits at the approximate locations shown on Plate 2. Boring logs from a report by Dames & Moore for the site, dated January 15, 1987 were also reviewed for this project. Detailed descriptions of the conditions encountered at each location explored are presented on the test pit logs, Plates A2 through A6. Copies of the Dames & Moore boring logs are also included in Appendix A. As requested, we performed a subsurface exploration across the entire site between Southwest 19th Street, Lind Avenue, East Valley Road and the Boeing Office complex. Borings and test pits were numbered sequentially; however, each report contains only those logs that were documented on the appropriate parcel. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind, LLC - I. c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 3 A description of the field exploration methods is included in Appendix A. Below is a generalized description of the subsurface conditions encountered. The general soil stratigraphy at the site was further evaluated with additional subsurface exploration on the other portions of the site, however, only logs for the subsurface exploration in the vicinity of the proposed business park buildings are included in this report. During our subsurface exploration, we observed up to twelve feet of fill consisting primarily of silty sand (Unified Soil Classification SM) with concrete rubble throughout. Concrete rubble ranged in size from gravel size up to slabs about three to four feet wide. Underlying the fill, the native soil consisted of peat interlayered with organic silt (OH') with moisture contents ranging from 105 to 277 percent. The peat was observed to be soft to medium stiff. Beneath the peat at about seventeen feet beneath the existing ground surface, our test pits encountered dark gray poorly graded sand with silt (SP-SM) and silty sand (SM), The Dames & Moore boring logs indicate the sand is loose to medium dense. Based on the boring logs, the sand grades into a well graded gravel beneath about twenty-five feet. At this depth the soil becomes dense to very dense. Groundwater The groundwater table was encountered between sixteen and seventeen feet in our test pit exploration conducted on March 24,1997. Groundwater levels were measured by Dames & Moore in December 1986 at about eight feet beneath the ground surface. It is important to note that groundwater levels are not constant; thus, one may expect fluctuations in the volume and location depending on the season, amount of rainfall, surface water runoff, and other factors. Generally, groundwater seepage is greater during the wetter winter months (typically October through May). Laboratory Testing Laboratory tests were conducted on several representative soil samples to verify or modify the field soil classification of the units encountered and to evaluate the general physical properties and engineering characteristics of the soils encountered. Visual classifications were supplemented by index tests, such as sieve analysis and Atterberg Limit tests, and moisture content tests on representative samples. The results of laboratory tests performed on specific samples are provided either at the appropriate sample depth on the individual test pit log or on a separate data sheet contained in Appendix B. However, it is important to note that these test results may not accurately represent the overall in-situ soil conditions; our geotechnical recommendations are based on our interpretation of these test results. The soil samples for this project will be discarded after a period of fifteen'(15) days following completion of this report, unless we are otherwise directed in writing. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 4 DISCUSSION AND RECOMMENDATIONS General Based on the results of our study, it is our opinion that the site can be developed generally as planned provided the recommendations contained in this report are incorporated into the final design. In our opinion, total settlement of the native soils, particularly the peat and organic silt, will be on the order of six to eight inches. In order to minimize post construction settlement, a surcharge program with footings bearing on at least two feet of structural fill or a pile foundation system should be used. The purpose of the surcharge program is to pre-induce most of the settlement estimated to result from building loads. The surcharge program should have a minimum height of three feet above finished floor elevations. We anticipate completion of the surcharge in eight to twelve weeks. It should be noted that, due to the very high moisture content of the peat and organic silt (277 percent), settlement from secondary consolidation may be significant. We estimate that after completion of a surcharge program,total settlement of the structures will be on the order of two inches. To reduce the estimated post-construction settlement to one and one-half inches, the surcharge height should be increased to five feet. This settlement will occur over a period of several years at a gradually slower rate. If the effects of this settlement cannot be tolerated then the building should be supported by a pile foundation. This report has been prepared for specific application to this project only and in a manner consistent with that level of care and skill ordinarily exercised by other members of the profession currently practicing under similar conditions in this area for the exclusive use of Martin Smith Real Estate Services and their representatives. No warranty is expressed or implied. It is recommended that this report, in its entirety, be included in the project contract documents for the information of the contractor. Site Preparation and Grading Construction areas should be stripped and cleared of existing vegetation, topsoil, organic debris, and other deleterious materials. Stripped organic materials should not be mixed with any soils to be used as structural fill. Following the stripping and clearing procedures, the earthwork operations can commence to provide the design grades. The ground surface where structural fill is to be placed should be proofrolled. Proofrolling should be performed under the observation of a representative of ECI. Soil in any loose or soft areas, if recompacted and still _ _ excessively yielding;should be overexcavated and replaced with structural fill to a depth that will provide a stable base beneath the general structural fill or suitable support for slabs. Earth Consultants, Inc. GEOTECHNICAL ENGINEERINU STUDY Southwest 19th Lind, LLC c/o Martin Smith 'Real Estate Services E-7608-1A April 15, 1997 Page 5 The soils exposed in our test pits are moisture sensitive due to their high fines content. As such, in an exposed condition they will become disturbed from normal construction activity especially when in a wet or saturated condition. Once disturbed, in a wet condition, they will be unsuitable for support of foundations or pavements. Therefore, during construction where these soils are exposed and will support new structures, care must be exercised not to disturb their condition. If disturbed conditions develop, the affected soils must be removed and replaced with a structural fill. The depth of removal will be dependent on the level of disturbance developed during construction. Structural fill is defined as any compacted fill placed under.foundations, roadways, slabs, pavements, or any other load-bearing areas. Structural fill under foundations should be placed in horizontal lifts not exceeding twelve (12) inches in loose thickness and compacted to a minimum 90 percent of its maximum dry density in accordance with ASTM Test Designation D-1557 (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. Soils expected to be exposed in the footing and utility excavations range from silty sand to peat. In our opinion, the sands are usable as structural fill, provided they are moisture conditioned to at or near optimum moisture content. In order to moisture condition the sand, it may be necessary to either add water or aerate the soil. However, the peat, which may be exposed in deeper utility trenches, should be removed and replaced with structural fill to a depth that will provide adequate support for the utility pipe. Structural fill which is to be placed in wet weather should consist of a granular material with a maximum size of three inches and no more than five percent fines passing the No. 200 sieve, based on the minus 3/4-inch fraction. During dry weather, most compactible non- organic soil can be used as structural fill. It is recommended that any structural fill planned for on site use be submitted for approval prior to import. Surcharge Program The surcharge program is designed to pre-consolidate the compressible fills and soil underlying the site, such that the surcharge would apply loads greater than anticipated building loads. The surcharge fill is in addition to the fill required to bring the site to grade. The surcharge should extend at least five feet beyond the perimeter of the buildings. The height of the surcharge should be three feet above finish floor. The side slopes of the fill should not be inclined any steeper than 1 H:1 V. If a wet weather construction schedule is planned, the _ _ surcharge fill should meet the requirements of a wet weather fill as discussed in the Site Preparation and Grading section of this study. The surcharge should be compacted to a density of one hundred twenty (120) pcf. Earth Consultants, Inc. • GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 6 Depending on site grades, it may be necessary to overexcavate soil to provide the required thickness of structural fill below footings and slabs prior to placement of the surcharge. Alternatively, footing overexcavations can be accomplished after removal of the surcharge. I The settlement induced by the surcharge should be in the range of six to eight inches. A smaller settlement should be interpreted as that the soils have been preconsolidated and soil conditions are better than anticipated. Conversely, a larger settlement could be interpreted that the soil conditions are worse than anticipated, and that additional time and measurements should be taken to obtain satisfactory results. However, the only reasonably accurate means of verifying the settlement magnitude is to perform a monitoring program. With completion of a three foot surcharge, post-construction settlements are anticipated to be on the order of two inches. To reduce the estimated post-construction settlement to one and one-half inches, the surcharge height should be increased to five feet. The settlement monitoring program should include setting settlement monitors on the existing site subgrade before any fill is placed, monitoring them through completion of fill placement, continuing until settlements cease or are considered within the buildings tolerable limits. More specific details of this program are presented below: • Settlement markers should be placed on the native subgrade of each building pad before any fill is placed. Six to nine markers should be installed within each building footprint. ECI can supply and install these markers. (A typical detail is provided on Plate 3). • A baseline reading is obtained on each marker and is referenced to a temporary benchmark located on a feature that will not be affected by the fill-induced settlements. • The fills are then placed. Settlement readings are taken at relatively short intervals during this process, since this phase generates relatively large and rapid settlement. • Once the fill operation is complete, readings are obtained on a periodic basis, typically weekly, until the settlement ceases or the anticipated future settlements are judged by the geotechnical engineer to be approximately two inches. • Each set of settlement readings are plotted graphically against time to determine the magnitude and rate of settlement, and are matched against the predicted . __ magnitudes and rates to verify the accuracy of earlier estimates and to make any appropriate modifications. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 7 ECI should be retained to acquire the settlement readings. If you prefer to use another organization to collect these readings, measurements should be provided to us as quickly after their acquisition as possible for plotting and interpretation. This will help avoid any misinterpretation or misunderstanding regarding the success of the surcharge program. The integrity of the settlement monitoring program must be maintained. In our experience, earthwork equipment (dozers, rollers, trucks, etc.) often demolish markers at a very high rate. This adds to the project costs in that they need to be replaced and it makes the information obtained less reliable. To avoid this scenario, it is suggested that the project specifications include a requirement that the earthwork contractor is required to immediately replace any damaged settlement marker and have the settlement readings reobtained at his own cost. This requirement makes the earthwork contractor more conscious of the importance of the preload program and will aid in maintaining the integrity of the monitoring program. Fill for landscaping purposes should not be placed near the building since additional fill could induce further settlements after the building is constructed. If such fill is planned, the surcharge should be extended to five feet beyond the planned landscape fill, or a lightweight fill, such as "hog fuel" be used. Foundations Based on the encountered subsurface soil conditions, preliminary addition design criteria, and assuming compliance with the preceding Site Preparation and Grading section, the proposed structures may be supported by a minimum of two feet of new structural fill. The foundation may be designed for an allowable soil bearing capacity of two thousand five hundred (2500) pounds per square foot (psf) when bearing on at least two feet of structural fill. Structural fill should extend out from the edge of the footing at least one-half the depth of the overexcavation. Footings should be at least twelve (12) inches in width and extend to a depth of at least eighteen (18) inches below the lowest adjacent grade. The above allowable soil bearing value is for dead plus live loads and may be increased one- third for combined dead, live, wind, and seismic forces. It is recommended that all footing excavations be observed by a representative of ECI, prior to placing forms or rebar, to verify that exposed soil conditions are as anticipated in this report, and/or provide suitable modifications in the design, as required. Earth Consultants. Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 8 Without completion of the surcharge program, we estimate there is the potential for eight to ten inches of total settlement with about four to five inches of differential settlement. ' Following successful completion of the surcharge program, total settlements are expected to be about two inches for foundations bearing on structural fill. To reduce the estimated post- construction settlement to one and one-half inches, the surcharge height should be increased to five feet. Differential settlement is anticipated to be about one inch. About one-half of the anticipated settlement should occur as the dead and live loads are applied. Seismic Design Considerations The Puget Sound region is classified as Seismic Zone 3 by the Uniform Building Code (UBC). The largest earthquakes in the Puget Sound region have been subcrustal events, ranging in depth from 50 to 70 kilometers. Such deep events have exhibited no surface faulting. The UBC earthquake regulations contain a static force procedure and a dynamic force procedure for design base shear calculations. Based on the encountered soil conditions, it is our opinion that a site coefficient of 1 .5 should be used for the static force procedure, as outlined in Section 1628 of the 1994 UBC. For the dynamic force procedure outline in Section 1629 of the 1994 UBC, the curve for Soft to Medium Clays and Sands (Soil Type 3) should be used on Figure 16-3, Normalized Response Spectra Shapes. Liquefaction is a phenomenon in which soils lose all shear strength for short periods of time during an earthquake. The effects of liquefaction may be large total and/or differential settlement for structures with foundations founded in the liquefying soils. Groundshaking of sufficient duration results in the loss of grain to grain contact and rapid increase in pore water pressure, causing the soil to behave as a fluid for short periods of time. To have potential for liquefaction, a soil must be cohesionless with a grain size distribution of a specified range (generally sands and silt); it must be loose to medium-dense; it must be below the groundwater table; and it must be subject to sufficient magnitude and duration of groundshaking. Based on the subsurface information obtained during our field exploration, it is our opinion that the liquefaction potential at the site is moderate due to the relative density of the soils encountered and cohesive nature of the encountered silts. Should liquefaction occur, it will not be wide spread across the site and settlement due to liquefaction is estimated to be within the range provided in the Foundations section of this report. Earth Consultants, Inc. GEOTECHNICAL ENGINEERINi STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 9 Lateral Resistance An allowable passive pressure value against the sides of foundation, slabs or other subsurface foundation elements of three hundred (300) psf per foot of depth may be used for design. In order to fully mobilize the passive pressure, the foundations must be poured "neat" against the adjacent soil or the foundation excavation must be backfilled with structural fill. Friction between the base of foundations and the underlying soil may be assumed to be 40 percent of the dead load. The friction and passive pressure design values include a factor of safety of 1 .5. Retaining Walls Retaining walls and foundation walls that will act as retaining walls should be designed to resist lateral earth pressures imposed by the retained soils. Walls that are designed to yield can be designed to resist the lateral earth pressure imposed by an equivalent fluid with a unit weight of thirty-five (35) pounds per cubic foot (pcf). The equivalent fluid weight should be increased to 45 pcf for walls that are restrained at the top from free movement. These values are based on horizontal backfill and that surcharges due to backfill slopes, hydrostatic pressures, traffic, structural loads or other surcharge loads will not act on walls. If such surcharges are to apply, they should be added to the above design lateral pressures. Calculation of lateral resistance should be done using the passive pressure and coefficient of friction values contained in the previous section. Retaining walls should be backfilled with a free-draining material conforming to the WSDOT specification forgravel backfill for walls (WSDOT 9-03.12 2 . The free-drainingmaterial p ( )I should extend a minimum of eighteen inches behind the wall. The remainder of the backfill should consist of structural fill. A perforated drain pipe should be placed at the base of the wall. Drain pipes located in the free draining backfill soil should be perforated with holes less than 1/2-inch in diameter. The drain pipe should be surrounded by a minimum of one cubic foot per lineal foot with 3/4-inch rock or should be wrapped with a filter fabric. Slab-on-Grade Floors Slab-on-grade floors should be supported by a minimum of one foot of structural fill. Should loose soil be present at the slab subgrade elevation, it should be compacted to the requirements of structural fill. Disturbed subgrade soil must either be re-compacted or replaced with structural fill. Slab-on-grade floors should be designed by the structural engineer based on the anticipated loading and the subgrade support characteristics. A modulus of vertical subgrade reaction of three hundred (300) pounds per cubic inch (pci) may _ _ be used for design. Earth Consultants, Inc. GEOTECHNICAL ENGINEERINu STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 10 The slab should be provided with a minimum of four inches of free-draining sand or gravel. In areas where slab moisture is undesirable, a vapor barrier such as a 6-mil plastic membrane may be placed beneath the slab. Two inches of damp sand may be placed over the membrane for protection during construction and to aid in curing of the concrete. Excavations and Slopes In no case should excavation slopes be greater than the limits specified in local, state and federal safety regulations. As described in the current Occupational Safety and Health Administration (OSHA) regulations, soils anticipated to be encountered in excavations (fill and peat) would classify as Type "C." Therefore temporary cuts greater than four feet in height, should be sloped at an inclination no steeper than 1 .5H:1V in the Type "C" soils. If slopes of this inclination, or flatter, cannot be constructed, or if excavations greater than twenty (20) feet in depth are required, temporary shoring may be necessary. This shoring would help protect against slope or excavation collapse, and would provide protection to workmen in the excavation. If temporary shoring is required, we will be available to provide shoring design criteria, if requested. Although no permanent slopes are anticipated for the project due to the topography, permanent slopes should be inclined no steeper than 2H:1V. Earth Consultants, Inc. should be requested to observe any permanent slopes to confirm the soil conditions and provide recommendations to improve the stability of the slope should it be necessary. The above information has been provided solely as a service to our client. Under no circumstances should the above information be interpreted to mean that this office is assuming responsibility for construction site safety or the contractor's activities; such responsibility is not being implied and should not be inferred. Site Drainage The groundwater table was encountered between sixteen and seventeen feet in our test pit exploration conducted on March 24, 1997. Groundwater levels were measured by Dames & Moore in December 1986 at about eight feet beneath the ground surface. It is possible that groundwater levels will present construction related problems while excavating for the deeper utility trenches. Should groundwater seepage be encountered during construction,the bottom of the excavation should be sloped to one or more shallow sump pits. The collected water can then be pumped from these pits to a positive and permanent discharge, such as a nearby storm drain. Depending on the magnitude of such seepage, it may also be necessary to interconnect the sump pits by a system of connector trenches. It is recommended that the _ _ appropriate locations of subsurface drains, if needed, be established during grading operations by this office, at which time the seepage areas, if present, may be more clearly defined. Earth Consultants, Inc. GEOTECHNICAL ENGINEE',__:'G STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 11 The site should be graded such that surface water is directed off the site. Water should not be allowed to stand in any area where structures, slabs or driveways are to be constructed. During construction, loose surfaces should be sealed at night by compacting the surface to reduce the potential for moisture infiltration into the soils. Final site grades should allow for drainage away from the structure foundations. The ground should be sloped at a gradient of three percent for a distance of at least ten feet away from the structures in landscape areas. This gradient may be reduced to two percent in paved areas. Foundation drains should be installed where landscaped areas are immediately adjacent to the ' building. In our opinion, foundation drains are not necessary in areas where pavements extend to the building walls. The drains should be installed at or just below the bottom of the footing, with a gradient sufficient to initiate flow. A typical detail is provided on Plate 4. Utility Support and Backfill Based on the soil conditions encountered, the majority of soils expected to be exposed by utility excavations should provide adequate support for utilities; however, deeper utility trenches may encounter the peat that is beneath the existing fills. Should the peat, or soft soils, be exposed near pipe grades, the peat should be removed to a depth that will provide adequate support for the utility. Utility trench backfill is a major concern in reducing the potential for settlement along utility alignments, particularly in pavement areas. It is important that each section of utility line be adequately supported in the bedding material. The material should be hand tamped to ensure support is provided around the pipe haunches. Fill should be carefully placed and hand tamped to about twelve (12) inches above the crown of the pipe before any heavy compaction equipment is brought into use. The remainder of the trench backfill should be placed in lifts having a loose thickness of less than twelve (12) inches. A typical trench backfill section and compaction requirements for load supporting and non-load supporting areas is presented on Plate 5. Pavement Areas The adequacy of site pavements is related in part to the condition of the underlying subgrade. To provide a properly prepared subgrade for pavements, we recommend the subgrade be treated and prepared as described in the Site Preparation and Grading section of this report. This means at least the top twelve (12) inches of the subgrade should be compacted to 95 percent of the maximum dry density (per ASTM 1557-78). It is possible that some localized _ areas of soft, wet or unstable sub.grade may still exist after this process. Therefore, a greater thickness of structural fill or crushed rock may be needed to stabilize these localized areas. Earth Consultants, Inc. GEOTECHNICAL ENGINEE' .__ iG STUDY - Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 12 We recommend the following pavement section for lightly loaded areas: • Two inches of asphalt concrete (AC) over four inches of crushed rock base (CRB) material, or • Two inches of AC over three inches of asphalt treated base (ATB) material. Heavier truck-traffic areas will require thicker sections depending upon site usage, pavement - life and site traffic. As a general rule, you may consider for truck-trafficked areas the following sections: • Three inches of AC over six inches of CRB, or • Three inches of AC over four inches of ATB. Asphalt concrete (AC), asphalt treated base (ATB), and crushed rock base (CRB) materials should conform to WSDOT specifications. Rock base should be compacted to at least 95 percent of the ASTM D-1557-78 laboratory test standard. It should be noted that parking stall pavement sections assume no truck traffic. LIMITATIONS Our recommendations and conclusions are based on the site materials observed, selective laboratory testing and engineering analyses, the design information provided to us by you, and our experience and engineering judgement. The conclusions and recommendations are professional opinions derived in a manner consistent with that level of care and skill ordinarily exercised by other members of the profession currently practicing under similar conditions in this area. No warranty is expressed or implied. The recommendations submitted in this report are based upon the data obtained from the test pits. Soil and groundwater conditions between test pits may vary from those encountered. The nature and extent of variations between our exploratory locations may not become evident until construction. If variations do appear, ECI should be requested to re-evaluate the recommendations of this report and to modify or verify them in writing prior to proceeding with the construction. Earth Consultants, Inc. • GEOTECHNICAL ENGINEEI _ ,�G STUDY Southwest 19th Lind, LLC c/o Martin Smith Real Estate Services E-7608-1A April 15, 1997 Page 13 Additional Services This office will be available to provide consultation services relating to review of the final design and specifications to verify that our recommendations have been properly interpreted and implemented in the approved construction plans and specifications. In addition, it is suggested that this office be retained to provide geotechnical services during construction to observe compliance with the design concepts and project specifications, and to facilitate design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. It should be noted that it is generally in the best interests of the owner/client to maintain the same Soils Engineer during construction in order to obtain the project objective, with optimum quality control.

GLS bate Mar.'97 Checked DSL Date 3/31/97 1 Plate 5 APPENDIX A E-7608-1A FIELD EXPLORATION Our test pit exploration was performed on March 24, 1997. The subsurface conditions at the site were explored by excavating five test pits to a maximum depth of seventeen and one-half (17.5) feet below the existing ground surface. The test pits were excavated by Northwest Excavating with a track-mounted excavator. The approximate test pit locations were determined by pacing from existing on site landmarks. The locations of the test pits should be considered accurate only to the degree implied by the method used. These approximate locations are shown on the Boring and Test Pit Location Plan, Plate 2. The field exploration was continuously monitored by an engineer from our firm, ' who classified the soils encountered and maintained a log of each test pit, obtained representative samples, and observed pertinent site features. All samples were visually classified in accordance with the Unified Soil Classification System which is presented on Plate Al , Legend. Logs of the test pits are presented on Plates A2 through A6. The final logs represent our interpretations of the field logs and the results of the laboratory tests on field samples. The stratification lines on the logs represent the approximate boundaries between soil types. In actuality, the transitions may be more gradual. Representative soil samples were placed in closed containers and returned to our laboratory for further examination and testing.

CITY OF RENTON Planning / Building / Public Works MEMORANDUM DATE: September 9, 1997 TO: Jim Hanson, Mike Kattermann-Zoning Administrators FROM: Peter Rosen, Senior Planner SUBJECT: Lind Corporate Park- LUA97-099, ECF, SA There is an error in a site plan condition of approval that was adopted for the Lind Corporate Park. The condition requires a joint-use contract for the reciprocal parking agreement with the adjacent hotel projects. However,the condition erroneously identifies the joint-use parking agreement with the "adjacent parcel to the west,"while the intended hotel sites are located adjacent to the east of the subject site. The condition and a recommended correction follows for your concurrence. The applicant shall submit a joint-use contract for the reciprocal parking agreement with the adjacent parcel to the west east. The contract shall be for a minimum of 5 years and shall be subject to the approval of the Development Services Division and City Attorney, prior to the issuance of building permits. cc: Jana Huerter (w3csz..&.,s5 CONCURRENCE ®ATE - cl Y5 ATE NAME is - r ---- - - • »:»:»>:«::<:><:»:;>«:»»::<;::«:»>:»»»:>:::»>::><:;:>:»>:>:>><:<:»>: RRENT.Pf�\NNtN. .f7t�ll. f • :IDAVIT F..

The proposal includes 234 parking spaces. Access would be via two driveway cuts off SW 19th Street. LOCATION OF PROPOSAL: 19th Avenue SW east of Lind Avenue South LEAD AGENCY: City of Renton Department of Planning/Building/Public Works Development Planning Section The City of Renton Environmental Review Committee has determined that it does not have a probable significant adverse impact on the environment. An Environmental Impact Statement (EIS) is not required under RCW 43.21 C.030(2)(c). Conditions were imposed as mitigation measures by the Environmental Review Committee under their authority of Section 4-6-6 Renton Municipal Code. These conditions are necessary to mitigate environmental impacts identified during the environmental review process. Comments regarding the environmental determination must be filed in writing on or before 5:00 PM September 16 1997). Any aggrieved person feeling that the environmental determination of the Environmental Review Committee is based on erroneous procedure, errors of law or fact, error in judgment, or the discovery of new evidence that could not be reasonably available at the time of the determination may submit written comments. After review of the comments, if the Environmental Review Committee finds there is not sufficient evidence to amend its original determination, then there will be no further extension of the appeal period. Any person wishing to take further action would need to file a formal appeal within the original 15-day timeframe. Written comments must be filed with: Jana Huerter, Land Use Review Supervisor, City of Renton Development Services Division, 200 Mill Avenue South, Renton, WA 98055.

DETERMINATION OF NON-SIGNIFICANCE (MITIGATED) ADVISORY NOTES APPLICATION NO(S): LUA-97-099,SA,ECF APPLICANT: SW 19th Lind, LLC PROJECT NAME: Lind Corporate Park DESCRIPTION OF PROPOSAL: Proposal for two one-story buildings totaling 77,285 square feet in area, designed for office/flex industrial use. The proposal includes 234 parking spaces. Access would be via two driveway cuts off SW 19th Street. LOCATION OF PROPOSAL: 19th Avenue SW east of Lind Avenue South Advisory Notes to Applicant: The following notes are supplemental information provided in conjunction with the environmental determination. Because these notes are provided as information only, they are not subject to the appeal process for environmental determinations. FIRE 1. The preliminary fire flow is 5,000 GPM. Five fire hydrants are required. This requires one hydrant within 150 feet of the building and four additional hydrants within 300 feet of the building. A looped fire main is required by City Ordinance. 2. Full sprinkler and fire alarm systems are required. Separate plans and permits are required by the Fire Department. BUILDING 1. Separate building permits are required per building. 2. Occupancy separations required based on use of future tenants. PLAN REVIEW Water 1. Preliminary fire required by the Fire Department is 5,000 gpm. A 10-inch water pipe will only supply 3,800 gpm. Therefore, a 12-inch or larger pipe size in the loop will be required. 2. No trees or shrubs allowed over loop water mains as shown on the Landscape plan. Loop water main and easement to be located in the drive lane of the parking lot and clear of parking stalls. 3. Consideration needs to be given to relocate the water meter for the south building into the planter area with the vault for the fire DDCVA. It is marked in red on the plan. 4. Show the irrigation meter, backflow device and location on the water plan. 5. Irrigation and domestic water meter sizes need to be shown. 6. A stubs cap, off the water main, is to be installed with a 2-inch blow-off. 7. Vertical profile to be provided with construction plans. 8. The System Development Connection charge for water is$0.129 per square foot of gross site area. 9. The existing fire hydrant on SW 19th Street, east of the westerly driveway may need to be relocated out of the proposed new sidewalk. 10. Construction plans to be provided to City of Renton Standards. The gross site area and impervious area needs to be shown on the title sheet of the construction plans. Storm/Surface Water 1. The following comments do not appear to have been addressed from the previous comments regarding April 25, 1997 memo from Scott Woodbury and the memo from Neil Watts dated April 17, 1997. a. Combined stormwater facilities with those of other projects in the short plat require a maintenance and operations agreement and easements would be needed between the parties involved. b. The preliminary site report needs to clearly note the datum throughout the report. Note page two of preliminary report next to last paragraph: Reference to the two existing 24-inch pipes are actually 12-inch pipes. Sheet attached for your convenience. c. Wetlands Report, Appendix C: Item 7Ai states the wetland is not associated with a lake, river, or estuary. However,the wetland is associated to Rolling Hills Creek according to the Department of Ecology which has mapped the wetland as a Shoreline of the State. Rolling Hills Creek flows in the 60"storm drain in SW 19th Street that the wetland outlets to. The page is attached and redlined. Please address a change. 2. There is no indication the following comments on the Environmental Checklist have been addressed: a. Section B.3a.5 says the site is not within the 100-year floodplain. However,the site is mapped within the current FEMA floodplain. A more appropriate response would have been that the portion of the site is mapped as floodplain, but that the site has been filled and is no longer floodplain, if in fact no portion of site is below the FEMA elevation. It is important to remember that FEMA is now on a different datum than the current City of Renton datum. If there are still areas below the FEMA floodplain,then compensatory storage must be provided. 3. From Neil Watts memo the following items need to be addressed: a. A maintenance and operations agreement must be implemented between the newly created parcels to insure the benefits and responsibilities of this facility will be shared by all the parcels of the short plat. 4. System Development Charge for surface water is$25,927 subject to approval and recording short plat. 5. The Preliminary Grading and Storm plan does not show the invert elevation of the new 36-inch pipe at the wetlands outfall. This needs to be shown on the Construction Plans. Wastewater 1. The wastewater system Development Charge is$18,561.03. 2. The sewer extension lines to the sewer main to be labeled "Private". 3. The installation of a sprinkler system will require floor drains to be tightlined to the sanitary sewer system. 4. Construction drawings to conform to the City of Renton drafting standards. 5. A vertical profile will be required on the construction plans. 6. A line cleanout is required to be located 5-ft. from the building. 7. No trees or shrubs allowed over the sewer main as shown on the Landscape plan. The sewer main is to be located in the parking lot drive lane clear of the parking stalls and separated 10-feet from the water main. Transportation 1. An existing storm drain manhole lid is located in the proposed westerly driveway of SW 19th St. This is not a desirable location for a lid. AIRPORT The proposed project is located beneath the Airport's Horizontal Surface. The ground elevation of the project site is approximately 23 feet,with building elevations of approximately 26 feet. The finished building altitude of 49-50 feet is below the Horizontal Surface elevation. The proposed project is situated within the Airport's Horizontal Surface and may be impacted by low flying aircraft of all types throughout the 24-hour day from both the Renton Airport and the King County International Airport. Approval of the project and issuance of the permits constitutes acceptance by the owner that the use is a compatible uses, consistent with the operation of the airport. POLICE-40 Police Calls for Service Estimated Annually CONSTRUCTION PHASE Theft from construction sites is one of the most common reported crimes in the city. To protect materials and equipment it is recommended that all materials and tools be locked up when not in use. The site will need security lighting and should also be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems. I also recommend the business post the appropriate "No Trespassing"signs on the property while it's under construction (flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. COMPLETED PROJECT A business of this type is anticipated to be victimized by the following types of criminal activity: auto theft,theft from motor vehicle, commercial burglary, vandalism, and thefts of building materials and tools during the construction phase. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems. One of the steps that can be taken to prevent the above mentioned crimes is to provide proper lighting in and around the parking area. When you have a high volume of parked vehicles, this tends to attract car prowlers and auto thieves. A coded entry should be installed at all entrances of the building. This will deter trespassers from entering the building without authorization. All landscaping should be kept manicured and spaced appropriately to provide casual surveillance onto the property. Criminals generally wish to be hidden from view while they're conducting their unlawful activities. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems.

Building I fronts SW 19th Street and is 36,360 square feet. Building Ills 40,925 square feet and it is located behind and to the north of Building I. The buildings would be approximately 26 feet in height. A second floor mezzanine area is indicated as a possible expansion in the corners of the buildings. The buildings are intended as a "business park, flex/tech facility", and are designed to'be flexible for accommodating multi-tenant occupancies over various lease periods. It is anticipated that tenants would utilize a minimum of 20% of their area as office with the remainder of the floor area varying according to tenant need for storage, light assembly, repair, service, research- development, testing and/or manufacturing use. The buildings are L-shaped and paired to configure an interior loading/service court with dock-high doors that are screened from adjacent development and view from the street. The building facades which face outward have office entrances with tinted glass and landscaped entries. Customer and employee parking is arranged around the perimeter of the site. The proposed project is intended to appear as an office development from the frontages, limiting the dock-high doors and loading/distribution functions from view and as an accessory function to the office and light industrial uses. The proposed project is located on the 2 middle parcels (comprising 5.47 acres) of the 14.47 acre SW 19th Street Lind short plat (LUA97-032, SHPL). Directly to the east of the subject site are two approved hotel projects that are anticipated to begin construction. There is a driveway connection linking the subject proposal to the hotels, primarily for access to a reciprocal parking arrangement along the east portion of the subject site. Common stormwater facilities are intended to serve all development that is anticipated on the short plat lots. The stormwater detention vault for the system is located on the south portion of the subject project. The short plat parcels west of the subject site are presently undeveloped. North of the proposed project and short plat are two existing office buildings known as the Boeing "flashcubes." Access to the proposal is via 2 driveway cuts along SW 19th Street. 234 parking stalls located around the perimeter of the site are proposed for customer and employee parking. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 4321C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: SITERC.DOC • City of Renton P/B/PW Department Administrative Site Plan Approval&Envir ante!Review Committee Staff Report ' LIND CORPORATE PARK LUA-97-099, SA,ECF REPORT OF AUGUST 26, 1997 Page 3 of16 1. Earth Impacts: The site is generally level except for some small depressions due to previous inconsistent fill placement. The site has been previously filled and it is estimated that the fill is approximately 8 to 10 feet deep and consists of silty sand with concrete rubble throughout. Underlying the fill, the native soil consists of peat interlaced with organic silt and elastic silt. The Geotechnical Engineering Study (prepared by Earth Consultants Inc.) specifically addresses a potential development to the west of the subject site and therefore the recommendations for structural fill and foundations do not completely apply to conditions on the subject site or to the type of building proposed. It is anticipated that structural fill would be required to pre-load building pads, roadways, and other load-bearing areas. The environmental checklist prepared by the applicant indicates that approximately 11,000 cubic yards of structural fill would be imported to the site. The source is not known at this time. The site would be stripped of existing vegetation and graded for asphalt and building areas. Erosion could occur during the construction phase of the project. Potential erosion impacts would be mitigated by City Code requirements for approval of a Temporary Erosion and Sedimentation Control Plan (TESCP) and a Construction Mitigation Plan and prior to issuance of Construction Permits. Mitigation Measures: No further mitigation is recommended. Nexus: NA 2) Air Impacts Impacts to air quality can be anticipated during construction and after occupancy of the proposed project. Impacts during construction would include increased levels of airborne particulates (especially dust) from disturbance of exposed soils. Construction impacts would be short term in nature and would be mitigated through best management practices of the required TESCP and with the Construction Mitigation Plan. Emissions from construction equipment exhaust would have a minor impact on local air quality. Exhaust from construction vehicles is regulated by State and City Codes. After construction the impacts would be associated primarily with vehicle exhaust from customer and employee traffic. Vehicle emissions are regulated by the State of Washington. Overall air impacts would be relatively minor in nature and not considered significant to warrant special mitigation measures. Mitigation Measures No further mitigation is recommended. Policy Nexus NA 3) Water Impacts There is no surface water or wetlands located on the site. South of the subject site across SW 19th street is a large Category I wetland area. The environmental checklist states that the site is not within the 100-year floodplain. Actually, the site is mapped within the current FEMA floodplain. However, the site has been filled and is no longer considered floodplain if no portion of the site is below FEMA. If there are still areas below the FEMA floodplain, then compensatory storage must be provided. The subject development is proposing to utilize a stormwater detention system which has been designed to serve all development anticipated on the 14 acre SW 19th Street SITERC.DOC City of Renton P/B/PW Department Administrative Site Plan Approval&Envii ental Review Committee Staff Report ' LIND CORPORATE PARK LUA-97-099, SA,ECF REPORT OF AUGUST 26, 1997 Page 4 of 16 Lind short plat. The proposed stormwater system includes an underground wet/ detention vault which is located along the south property line of the subject site. The wet/detention vault will also be sized to provide dead storage and sediment storage for water quality purposes, potentially eliminating the need for surface bioswales to provide stormwater quality treatment. Because the stormwater system is proposed as a common system with adjacent development, the applicant should provide an access, use, and joint maintenance easement agreement for the stormwater facility. The stormwater system has also been designed to utilize the wetland across SW 19th Street for stormwater detention. The applicant and developers of other parcels within the short plat have been working with City staff to obtain approval for using the wetland for purposes of stormwater detention, as allowed by the King County Surface Water Design Manual(KCSWDM). The wetland is considered "associated"with Rolling Hills Creek and is mapped as a shoreline of the state. The only work or development planned within the wetland area is for replacement of a culvert. City staff has issued a shoreline exemption for this development as the work is estimated to be less than $1,000 and therefore not considered a shoreline substantial development. Mitigation Measures The applicant shall provide an access, use, and joint maintenance easement agreement for the stormwater facility. The easement agreement shall be subject to the approval of the Development Services Division and the City Attorney, prior to the issuance of a Building Permit. Policy Nexus NA 4) Fire Protection Impacts The proposal would add new construction to the City which would potentially impact the City's Fire Department. A Fire Mitigation Fee applies to all new construction. The required mitigation fee is based on a rate of $0.52 per square foot of new construction. For the proposed development the fee is tentatively estimated at $40,188.20 (77,285 square feet X $0.52 = $40,188.20). The Fire Mitigation Fee is payable at the time that Building Permits are issued. Mitigation Measures The applicant shall pay the appropriate Fire Mitigation Fee at a rate of $0.52 per square foot of new construction. This fee is estimated at $40,188.20. The Fire Mitigation Fee is payable prior to the issuance of Building Permits. Policy Nexus Fire Mitigation Fee Resolution and adopting Ordinance, SEPA Ordinance. 5) Transportation Impacts Access to the proposed development would be via 2 driveway cuts off SW 19th Street. The driveways are approximately 400 feet apart. The proposed access onto SW 19th Street would allow truck traffic to safely access onto arterial streets, Lind Avenue and East Valley Road. The proposal would result in an increase in traffic trips and therefore would be subject to the City's Transportation Mitigation Fee. The Transportation Mitigation Fee is calculated to be $75 per each average daily trip attributable to the project. City staff has estimated that the project would generate a total of 1,110.59 new average daily trips. Therefore, the Traffic Mitigation Fee is estimated at $83,293.91 (1,110.59 trips x SITERC.DOC City of Renton P/B/PW Department Administrative Site Plan Approval&Envii_ ental Review Committee Staff Report ' LIND CORPORATE PARK LUA-97-099, SA,ECF REPORT OF AUGUST 26, 1997 Page 5 of16 $75 = $83,293.91). Trip generation for the proposed development has been estimated from the ITE Trip Generation Manual. The applicant has the option of providing a traffic study to justify a different number of estimated traffic trips, subject to the approval of the Development Services Division. The applicant has submitted a Construction Mitigation Plan which states that construction would be performed between the hours of 7:00 a.m. and 5:00 p.m. Monday through Friday, with a minimum of work occurring on weekends. The applicant estimates that 11,000 cubic yards of fill material would be imported to the site. This could result in approximately 1,100 truck trips. Construction-related truck traffic could impact traffic flows if occurring during AM or PM peak traffic flows. This truck traffic should be limited to off-peak hours. Mitigation Measures: The applicant shall be required to pay a Traffic Mitigation Fee of$75 for each average daily trip associated with the project. The traffic mitigation fee is estimated at$83,293.91 (1,110.59 trips x$75 = $83,293.91). This fee is payable prior to issuance of Building Permits. The Construction Mitigation Plan shall be revised to restrict hauling of fill material and construction related truck traffic to between the hours of 8:30 a.m. to 3:30 p.m. unless approved in advance by the Development Services Division. The revised Construction Mitigation Plan shall be submitted for approval prior to issuance of Construction Permits.

Because these notes are provided as information only, they are not subject to the appeal process for environmental determinations. FIRE 1. The preliminary fire flow is 5,000 GPM. Five fire hydrants are required. This requires one hydrant within 150 feet of the building and four additional hydrants within 300 feet of the building. A looped fire main is required by City Ordinance. 2. Full sprinkler and fire alarm systems are required. Separate plans and permits are required by the Fire Department. BUILDING 1. Separate building permits are required per building. 2. Occupancy separations required based on use of future tenants. PLAN REVIEW Water 1. Preliminary fire required by the Fire Department is 5,000 gpm. A 10-inch water pipe will only supply 3,800 gpm. Therefore, a 12-inch or larger pipe size in the loop will be required. 2. No trees or shrubs allowed over loop water mains as shown on the Landscape plan. Loop water main and easement to be located in the drive lane of the parking lot and clear of parking stalls. 3.- -Consideration needs to be given to relocate the water meter for-the south building into the planter area with the vault for the fire DDCVA. It is marked in red on the plan. 4. Show the irrigation meter, backflow device and location on the water plan. 5. Irrigation and domestic water meter sizes need to be shown. 6. A stubs cap, off the water main, is to be installed with a 2-inch blow-off. 7. Vertical profile to be provided with construction plans. 8. The System Development Connection charge for water is$0.129 per square foot of gross site area. 9. The existing fire hydrant on SW 19th Street, east of the westerly driveway may need to be relocated out of the proposed new sidewalk. 10. Construction plans to be provided to City of Renton Standards. The gross site area and impervious area needs to be shown on the title sheet of the construction plans. Storm/Surface Water 1. The following comments do not appear to have been addressed from the previous comments regarding April 25, 1997 memo from Scott Woodbury and the memo from Neil Watts dated April 17, 1997. a. Combined stormwater facilities with those of other projects in the short plat require a maintenance and operations agreement and easements would be needed between the parties involved. b. The preliminary site report needs to clearly note the datum throughout the report. Note page two of preliminary report next to last paragraph: Reference to the two existing 24-inch pipes are actually 12-inch pipes. Sheet attached for your convenience. c. Wetlands Report,Appendix C: Item 7Ai states the wetland is not associated with a lake, river, or estuary. However, the wetland is associated to Rolling Hills Creek according to the Department of Ecology which has mapped the wetland as a Shoreline of the State. Rolling Hills Creek flows in the 60"storm drain in SW 19th Street that the wetland outlets to. The page is attached and redlined. Please address a change. 2. There is no indication the following comments on the Environmental Checklist have been addressed: a. Section B.3a.5 says the site is not within the 100-year floodplain. However,the site is mapped within the current FEMA floodplain. A more appropriate response would have been that the portion of the site is mapped as floodplain, but that the site has been filled and is no longer floodplain, if in fact no portion of site is below the FEMA elevation. It is important to remember that FEMA is now on a different datum than the current City of Renton datum. If there are still areas below the FEMA floodplain, then compensatory storage must be provided.

From Neil Watts memo the following items need to be addressed: a. A maintenance and operations agreement must be implemented between the newly created parcels to insure the benefits and responsibilities of this facility will be shared by all the parcels of the short plat. 4. System Development Charge for surface water is$25,927 subject to approval and recording short plat. 5. The Preliminary Grading and Storm plan does not show the invert elevation of the new 36-inch pipe at the wetlands outfall. This needs to be shown on the Construction Plans. Wastewater 1. The wastewater system Development Charge is$18,561.03. 2. The sewer extension lines to the sewer main to be labeled "Private". 3. The installation of a sprinkler system will require floor drains to be tightlined to the sanitary sewer system. 4. Construction drawings to conform to the City of Renton drafting standards. 5. A vertical profile will be required on the construction plans. 6. A line cleanout is required to be located 5-ft. from the building. 7. No trees or shrubs allowed over the sewer main as shown on the Landscape plan. The sewer main is to be located in the parking lot drive lane clear of the parking stalls and separated 10-feet from the water main. Transportation 1. An existing storm drain manhole lid is located in the proposed westerly driveway of SW 19th St. This is not a desirable location for a lid. AIRPORT The proposed project is located beneath the Airport's Horizontal Surface. The ground elevation of the project site is approximately 23 feet,with building elevations of approximately 26 feet. The finished building altitude of 49-50 feet is below the Horizontal Surface elevation. The proposed project is situated within the Airport's Horizontal Surface and may be impacted by low flying aircraft of I all types throughout the 24-hour day from both the Renton Airport and the King County International Airport. Approval of the project and issuance of the permits constitutes acceptance by the owner that the use is a compatible uses, consistent with the operation of the airport. POLICE-40 Police Calls for Service Estimated Annually CONSTRUCTION PHASE Theft from construction sites is one of the most common reported crimes in the city. To protect materials and equipment it is recommended that all materials and tools be locked up when not in use. The site will need security lighting and should also be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems. I also recommend the business post the appropriate"No Trespassing"signs on the property while it's under construction (flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. COMPLETED PROJECT A business of this type is anticipated to be victimized by the following types of criminal activity: auto theft,theft from motor vehicle, commercial burglary, vandalism, and thefts of building materials and tools during the construction phase. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems. One of the steps that can be taken to prevent the above mentioned crimes is to provide proper lighting in and around the parking area. When you have a high volume of parked vehicles,this tends to attract car prowlers and auto thieves. A coded entry should be installed at all entrances of the building. This will deter trespassers from entering the building without authorization. All landscaping should be kept manicured and spaced appropriately to provide casual surveillance onto the property. Criminals generally wish to be hidden from view while they're conducting their unlawful activities. The use of a private security guard patrol of off-duty officers is recommended as auxiliary security if the business experiences problems.

Consistency with Site Plan Criteria In reviewing the proposal with respect to the site Plan Approval Criteria set forth in Section 4-31- 33(D) of the Site Plan Ordinance, the following issues have been identified by City Departmental Reviewers and Divisional Reviewers: 1. GENERAL CRITERIA: A. CONFORMANCE WITH THE COMPREHENSIVE PLAN, ITS ELEMENTS AND POLICIES; The subject site is within the Employment Area-Valley (EAV) designation of the Comprehensive Plan. The EAV designation is intended to provide for a mixture of office, industrial and commercial uses. The proposed office/light industrial use falls within the range of uses anticipated for the designation. The proposal is consistent with the following applicable EAV policies: Policy LU-212.1 Develop the Renton Valley and the Black River Valley areas as a place for a range and variety of commercial, office, and industrial uses. Policy LU-212.2 Compatible and related land uses should be encouraged to locate in proximity to one another. Policy LU-212.7 Non-traditional uses such as research, design, and development facilities should be allowed in office designations and industrial designations when their impacts to surrounding uses can be mitigated. The site plan incorporates a number of elements which are consistent with the EAV Comprehensive Plan policies listed below. The site plan elements proposed include: shared facilities such as parking and site access, street trees along street frontages, and landscaping to screen parking areas. Policy LU-212.6 Developments should be encouraged to achieve greater efficiency in site utilization and result in benefits to users with techniques including: a. shared facilities such as parking and site access, recreation facilities and amenities; b. an improved ability to serve development with transit by centralizing transit stops; and c. an opportunity to provide support services (e.g. copy center, coffee shop or lunch facilities, express mail services) for nearby development that otherwise might not exist. Policy LU-212.21 Vehicular connections between adjacent parking areas are encouraged. Incentives should be offered to encourage shared parking. Policy LU-212.19 Street trees and landscaping should be required for new development within the Valley to provide an attractive streetscape in areas subjected to a transition of land uses. Policy LU-212.20 When more intensive new uses are proposed for locations in close proximity to less intensive existing uses, the responsibility for mitigating any adverse impacts should be the responsibility of the new use. Policy LU-291. Beautification and screening of parking lots should be encouraged through appropriate landscaping, fencing and berms. (Community Design policies) SITERC.DOC City of Renton P/B/PW Department Administrative Site Plan Approval&Envi rental Review Committee Staff Report • LIND CORPORATE PARK LUA-97-099,SA,ECF REPORT OF AUGUST 26, 1997 Page 11 of 16 B. CONFORMANCE WITH EXISTING LAND USE REGULATIONS; The subject site is zoned Commercial Office (CO). The project narrative states that anticipated tenants within the buildings would utilize a minimum of 20% of their area as office with the remainder of the floor area varying according to tenant need for storage, light assembly, repair, service, research-development, testing and/or manufacturing use. Offices (administrative/ headquarters) are allowed as a primary permitted use in the CO zone. Light industrial uses are permitted as a secondary use in the CO zone with condition to consider community need (i.e. suitable location). Light industrial uses specified in the CO zone include: 1) Research, development, testing, 2) Electronics, manufacturing and assembly, 3) Manufacturing, assembling and packaging of articles, products or merchandise from pre-processed natural or synthetic materials. The manufacturing use is not further defined but appears to include all lower-intensity industrial uses that do not involve a primary transformation of materials or substances into new materials or substances. Indoor storage is also specified as a secondary use with no limit on the area devoted to storage if it is associated with a mixed office/light industrial or mixed office/ manufacturing complex. The proposal does not include specific users or tenants with the application. However, the design and layout of the proposed buildings and the intended users/tenants appears to be consistent with the uses allowed in the CO zoning designation. The uses of future building tenants would be reviewed for zoning compliance during the review and approval of business license applications. The site plan complies with the development standards of the CO zone. The building is setback approximately 85 feet from the front property line along SW 19th Street, meeting the 20 foot minimum 20 foot setback requirement. The proposal includes a 15 foot wide landscape strip with street trees along SW 19th Street where the code requires a 10 foot wide landscape strip. No rear or side yard setbacks are required in the CO zone, though the proposed buildings are setback at least 50 feet from rear and side property lines. A minimum 5 foot wide landscape strip separates the perimeter parking from adjacent lots. The CO code requires a pedestrian connection to be provided between a building's public entrance and the street. The site plan provides a visible and easily-accessible pedestrian connection from the sidewalk to building entries. The proposed building coverage would be approximately 33% of the total site area. The CO zone allows up to 65% lot coverage for buildings. The site plan proposes 11,211 square feet of interior parking lot landscaping, which equals approximately 9% of the parking lot area. The Parking Code requires a minimum of 5% of a large parking area to be provided as interior parking lot landscaping. The subject site is within the Green River Valley Planning area. An environmental mitigation agreement between the City and the Soil Conservation Service (SCS) requires that 2% of a site area be provided as a natural landscape area for wildlife habitat. The proposal landscape plan indicates 4,919 square feet (4,759 square feet is required) of natural landscape area along the north property boundary. The landscaping is included in a 10 foot wide landscape strip between the parking area on the subject site and the adjacent office development north of the site. The proposal would be contiguous to the natural landscape area provided by the hotel development to the east of the site, and consolidation of natural landscape areas is encouraged by the code. The proposal includes a total of 234 parking spaces, which equals a ratio of 3.03 parking stalls per 1,000 square feet of floor area. The code sets parking requirements based on the type(s) of uses proposed. For example; manufacturing, research & development uses require a minimum of 1 to a maximum of 1.5 parking spaces per 1,000 square feet, office uses require a minimum of 3 to a maximum of 4.5 parking spaces per 1,000 square feet, and warehouse storage use requires 1 parking space per 1,500 square feet of gross floor area. The proposal does not include specific ' SITERC.DOC City of Renton P/8/PW Department Administrative Site Plan Approval&Envi. ;ental Review Committee Staff Report LIND CORPORATE PARK LUA-97-099,SA,ECF REPORT OF AUGUST 26, 1997 Page 12 of 16 uses or tenants for determining required parking. The applicant is providing a ratio of 3 parking spaces per 1,000 square feet of floor area which meets the parking requirements for office use, which requires the highest ratio of parking. The applicant anticipates that tenants would utilize a minimum of 20% of the floor area with office use and the remainder with storage and light industrial uses which have lower parking needs. It appears that sufficient parking is provided on the site in that it meets the parking code requirement for the most intensive type of use anticipated within the development. The project submittal does not discuss the fact that a reciprocal parking agreement with the hotels applies to the 48 parking stalls along the east project boundary. The reciprocal parking agreement was approved by the City with the building permit application for the hotel developments and it has been recorded. The reciprocal parking arrangement is justified because of the different peak time parking requirements between hotel and office uses. The proposed buildings would cross lot lines that were created with the SW 19th Street Lind Short Plat application (LUA97-032, SHPL). The applicant should either complete a lot line adjustment or record a covenant restricting the sale of one of the lots. The proposal intends to utilize a common stormwater system that has been designed to serve all the development associated with the SW 19th Street Lind Short Plat. This issue is discussed in this report under the Water element of the environmental review section. The stormwater system would release to an existing wetland across SW 19th Street and the wetland is planned to be used for stormwater detention. The wetland is considered "associated"with Rolling Hills Creek and is mapped as a shoreline area. The only work or development planned within the wetland area is for replacement of-a culvert. City staff has issued a shoreline exemption for this development as the work is estimated to be less than $1,000 and therefore not considered a shoreline substantial development. C. MITIGATION OF IMPACTS TO SURROUNDING PROPERTIES AND USES; The proposed office/flex tech development is part of the Lind Corporate Park, mixed-use development. The subject development is not anticipated to create adverse impacts on surrounding properties or uses. Two 4-story hotels have been approved on parcels directly to the east of the subject site. The back of the hotel buildings are oriented toward the subject site and there is a 15 foot wide landscape buffer between the sites. This should effectively mitigate potential conflicting activities between the uses. The subject proposal is configured so that dock-high doors and the service/loading areas for the buildings are contained within an interior service court. This would screen the service/loading areas from adjacent development and from street view. There would be some truck traffic activity along the perimeters of the site before entering the service/loading court. Landscaping along parcel boundaries and the orientation of surrounding buildings would further mitigate impacts of truck traffic. Adjacent to the north of the subject site is an existing office development. The proposal includes a heavily landscaped 10 foot wide buffer along the north property boundary which would buffer activities between the sites. D. MITIGATION OF IMPACTS OF THE PROPOSED SITE PLAN TO THE SITE; The subject site has been previously filled and the existing vegetation and natural features present on the site are relatively insignificant. Construction activities related to the proposed development SITERC.DOC City of Renton P/B/PW Department Administrative Site Plan Approval&Envi,_ .,rental Review Committee Staff Report LIND CORPORATE PARK LUA-97-099,SA,ECF REPORT OF AUGUST 26, 1997 Page 13 of16 would be required to utilize best management practices which would reduce potential construction impacts on the site. Required utility improvements, including the stormwater drainage system, would be designed to mitigate the potential impacts of the proposed development on the site. Therefore, the construction and operation of the development is not anticipated to adversely impact the subject site. E. CONSERVATION OF AREA-WIDE PROPERTY VALUES; The proposal is anticipated to conserve property values in the vicinity of the site. F. SAFETY AND EFFICIENCY OF VEHICLE AND PEDESTRIAN CIRCULATION; Access is proposed via 2 driveway cuts onto SW 19th Street. The driveway cuts are separated by approximately 400 feet which is an adequate offset distance. The subject proposal anticipates tenants/users that would generate truck traffic. Truck traffic would enter City arterial streets, East Valley Road and Lind Avenue, off SW 19th Street which is a preferable truck circulation pattern to direct driveway access onto the arterials. The proposal includes an interior service/loading court with dock-high doors. The backout area between the dock-high doors is 121 feet. The code specifies a 100 feet of backout area but there is no standard for where dock-high doors are back to back. The docks are staggered so it appears there is adequate backout area for maneuvering of trucks. In addition, the applicant has indicated that smaller trucks, (35 to 40 feet in length as opposed to truck trailers 55 to 60 feet in length), are expected to service the types of tenants anticipated to occupy the development. The proposed site plan includes visible and easily accessible pedestrian connections between the sidewalk along SW 19th Street and the building entries for Building I. There are no sidewalks proposed for pedestrian circulation through the site. It is anticipated that customers and employees would park close to building entries. G. PROVISION OF ADEQUATE LIGHT AND AIR; The proposed buildings are sufficiently setback from property boundaries and existing buildings to allow for adequate light and air circulation to the building. H. MITIGATION OF NOISE, ODORS AND OTHER HARMFUL OR UNHEALTHY CONDITIONS; The proposed development is not expected to create any harmful or unhealthy conditions. Noise, dust, and odors which may result from construction of the project would be mitigated through measures described in the Construction Mitigation Plan and with best management practices. 1. AVAILABILITY OF PUBLIC SERVICES AND FACILITIES TO ACCOMMODATE THE PROPOSED USE;AND The project site is adequately served by utilities and roads. The applicant will be responsible for extension of utilities on-site to serve the buildings. See the Advisory Notes section of this report for detailed information concerning utilities and public services.

PREVENTION OF NEIGHBORHOOD DETERIORATION AND BLIGHT. The proposal would serve to prevent neighborhood deterioration and blight by improving a vacant site with a use that is compatible with surrounding uses in the neighborhood. The anticipated uses and the design of the proposal has been closely coordinated with other development of the Lind Corporate Park, creating a cohesive image for the vicinity.

Some of the crimes that occur are burglary, vandalism, graffiti, trespassing, drug dealing and robbery in the parking lots. There is a way for police and business owners to discourage these types of crimes from taking place on private property, and that is by enforcing the City of Renton's Municipal Trespass Code 6-18-10. In order for police to be able to make an arrest for Trespass, business owners or managers need to purchase signs and display them in conspicuous areas on the property. These signs need to include the following language: 1. Indicate that the subject property is privately owned and; 2. Uninvited presence on the specified property is not permitted during the hours the business is closed,. and; 3. Violators will be subject to criminal sanctions pursuant to Renton City Code 6-18-10. MOST IMPORTANTLY-THE SIGNS SHOULD BE CONSPICUOUS FROM ALL POSSIBLE POINTS OF ENTRY TO THE PROPERTY,AND ALSO BE PLACED ON THE EXTERIOR OF THE BUILDINGS. This way when a suspect is arrested, he/she will not be able to claim as a defense that he/she did not know he or she was trespassing. EXAMPLES FOR TRESPASS SIGNS: NO TRESPASSING NO TRESPASSING This is private property. Persons without specific No Trespassing after business hours business are not authorized to be on the premises between (insert specific. times). Anyone on the the hours of(insert the hours your business is closed). premises after business hours is subject to Violators are subject to arrest and/or citation for criminal arrest and/or citation for Criminal Trespass pursuant to Renton City Code#6-18-10.. Trespass and/or impoundment of vehicle. Per Renton City Code#6-18-10. By enforcing the Trespass Ordinance, business owners and police will be sending a message to criminals that they are not allowed to conduct criminal activity on the property. In making arrests for Trespass, police may be preventing the more serious crimes from taking place. c �,,� COURTESY OF RENTON POLICE DEPARTMENT • 4 • CRIME PREVENTION UNIT `N'r° 235- 2571 ' A • • O CC A )•es% • r'*71.1r*W2,: .�i'G'i?.3.�.;1i•t n•�:'.',ryevKnwarrrwr,.•.:.:+wnc.er•wuwi.+xY.,rn,2;N..:voa�oN...»c.s,�.e: : -,/«yy�*' twswwnl►.. w,.,. . . .

However,the wetland is associated to Rolling Hills Creek according to the Department of Ecology which has mapped the wetland as a Shoreline of the State. Rolling Hills Creek flows in the 60" storm drain in SW 19th Street that the wetland outlets to. Any outfall to the wetland would therefore be subject to the Shoreline Master Program. The page is attached as redline. Please address a change. 2. There is no indication the following comments on the Environmental Checklist have been address: a. Section B.3a.5 says the site is not within the 100-year floodplain. However,the site is mapped within the current FEMA floodplain. A more appropriate response would have been that the portion of the site is mapped as floodplain, but that the site has filled and is no longer floodplain,if in fact no portion of site is below FEMA. It is important to remember that FEMA is now on a different datum that the current City of Renton datum. If there are still areas below the FEMA floodplain,then compensatory storage must be provided. b. Section A.10 fails to list that a shoreline permit would be required for work within the wetland or if water is discharged to the wetland. Also a Corps of Engineers Section 404 permit may be required for the proposed discharge and outletpipe replacement. The applicant is responsible for checking with the corps regarding their permit requirements,if any.. 3.

When the individual lots are developed, their storm drainage systems can then tie into the provided stubs. Water quality for the entire project will be provided in the wet/detention vault located along the south - property line of the site. The vault is designed using the February 1996 draft of the King County Surface Water Design Manual, which is a method of analysis based on computer modeling using the King County Runoff Time Series (KCRTS) model. The City of Renton requires the wetpond to be 1.5 to 2 times the design surface area and volume as calculated using the 1990 KCSWDM Design Standards if a biofiltration swale does not precede it. t. Using the KCRTS method of design, the vault is approximately 1.8 times the surface area and 2.7 times the volume requirements of the 1990 KCSWDM. The wetpond design calculations are contained later in this report. The wetland on the property south, of the project is approximately 10 acres in size. The developer proposes to use this wetland as one of his two means of peak rate runoff control and detention. Special requirement No. 8 of the King County Surface Water Design Manual specifies that the increased volume of runoff from the proposed , project may not increase the 100-year floodplain elevation of a wetland more than 0.1 feet. Based on sthis requirement and the area of the wetland we have estimated, approximately 40,000 cubic feet of T storage is available. 4. Also contained in this report are the calculations for a standard detention system based on City of Renton requirements. These requirements require the developer to match the peak flows of the 2-and , 10-year design storm events and increase the required storage volume by 30 percent above the 10-year ' # design storm event. Based on a total build out of the project assuming 90 percent impervious area, a4 the required storage volume would be approximately 60,000 cubic feet. The difference between volume required and volume provided by the wetland is 20,000 cubic feet. This difference must be tx detained on site. t 1. Based on the preliminary water quality calculations, the surface area required for the wet vault is .,, approximately 10,400 square feet. Therefore, 2 feet of storage above the static water surface elevation of the wet vault will provide the necessary on-site storage to make up the 20,000-cubic foot y difference. if it is determined that the wetland cannot provide the assumed storage, additional storage will be provided in the on-site wet/detention vault.

This "Business Park, Flex/Tech" facilities on a 5.47 acre site project consists of two buildings designed to be flexible to accommodate multi-tenancy occupancy over various lease periods. Anticipated use per tenant could vary from a minimum of 20% office with the rest of the tenant space in storage, light assembly, repair, service, research- development, testing and/or manufacturing, throughout the life time of the project. Building areas total 77,285 SF, cover 33% of the site, and provides 234 parking stalls with mutual parking easements with the pending hotel complex to the east. Typical facilities have office entrances with glass at the front of the building, truck doors and dock high doors at the rear of the building in the service courts. The service court can also provide additional parking depending on occupancy. The buildings are "paired" back to back to screen the loading/service courts from office areas and 'adjacent developments. Proposed buildings are concrete tilt up panels with articulated reveals and varying color tones to accentuate patterns and proportion the buildings. Buildings are 26 feet high to top of parapet. Entry areas for office are recessed with tinted glass, access walks, and landscaping. A second floor mezzanine area is also possible in sections of the building. Landscape buffers are provided at the development perimeters and adjacent to the buildings. Landscape islands distributed throughout the parking areas. The service court areas are landscaped at the main entry areas only to facilitate maneuvering. Improvements would include a wet vault for water quality with improvements and extension of on-site utilities as part of development. Current use of the site is undeveloped in the C.O.

This site plan submittal is 5.47 acres and consists of two buildings designed to be flexible to accommodate multi-tenancy occupancy over the various lease periods of the "Business Park, Flex/Tech" facilities. Anticipated use per tenant could vary from 20% office with the rest of the tenant space in storage, light assembly, repair, service, • research-development, and manufacturing throughout the life time of the project. Typical facilities have office entrances with glass at the front of the building and truck doors and dock doors at the rear of the building in the service courts, which can also provide additional parking. The buildings are "paired"to self screen the loading/service courts from office areas and adjacent developments. Proposed buildings are concrete tilt up panels with articulated reveals and varying color tones to accentuate patterns on the buildings. Buildings are 26 feet high to top of parapet. Entry areas for office are recessed with tinted glass, access walks, and landscaping. Landscape buffers are provided around the development perimeters and adjacent the buildings.

Berg President LPN Architecture and Planning, Inc. 1201 Fourth Avenue S., Suite 102 Seattle,WA 98134 SUBJECT: BUSINESS PARK/OFFICE FLEX-TECH INDUSTRIAL USE Dear Mr. Royce: Thank you for your letter of•March 18, 1997, requesting clarification of whether your `Business Park"use would be allowed in the Commercial Office (CO) Zone. By your description, the proposed use would include manufacturing with accessory indoor storage of goods and material as well as office space. You also noted that this would not be a distribution facility. To maintain compatibility with the primary office functions, manufacturing uses are limited in the CO Zone. Certain light industrial uses are permitted as Secondary Uses. These include: • Research, development and testing; • Electronics manufacturing and assembly;,and, • Manufacturing, assembling and packaging of articles, products or merchandise from pre- ' processed natural or synthetic materials. (RMC 4-31-16B.2.d) The last light industrial use is not defined but appears to include all lower-intensity industrial uses that do not involve a primary transformation of materials or substances into new materials or substances. The CO Zone also allows Indoor Storage as a Secondary Use, 'If part of a mixed office/light industrial or mixed office/manufacturing complex': (RMC 4-31-16B.2.p) It appears that the proposed development would be considered one of the two. In the event that it is determined the development does not fit into either the office/light industrial or the office/manufacturing categories, limited accessory storage is allowed separately in the CO Code. 'Storage (interior) of goods and materials ordinarily associated with a permitted use"is listed as an Accessory Use and is limited to thirty-three percent (33%) of the gross floor area. (RMC 4-31-16B.3.g) The thirty- three percent limit can be exceeded for a specific use by Administrative Conditional Use permit, providing that adverse impacts are mitigated and that the average amount of indoor storage does not exceed thirty-three percent of the floor area for the total development. (RMC 4-31-16B.4.j) 200 Mill Avenue South - Renton, Washington 98055 .0 . Page 2 April 11, 1997 All Secondary Uses in the CO Zone are subject to a determination of "community need (i.e. suitable location)"! "Community need"is elaborated under the Conditional Use Section of the Zoning Code (RMC 4-31-36C.2.) as being determined'by, among other relevant information, the following factors: • The proposed location shall not result in either the detrimental over-concentration of a particular use within the City or within the immediate area of the proposed use. • That the proposed location is suited for the proposed use. It appears that the Zone allows a broad range of possible tenant uses for your proposed development and What you have described in your letter would be allowed. I hope this provides some assistance. If you have additional questions,' please call Jana Huerter, Manager of the Development and Planning Section, at 235-2518. Sincerely, 7/Z: C / Li Michael D.

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 NON PROJECT proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For NON PROJECT actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site",shoult be read as "proposal," "proposer,"and "affected geographic area,"respectively. ga CRAVD Ui 1397 DEVELOP". „IT PLANNING CITY OF RENTON Environmental Checklist A.

This report presents the results of our field exploration, selective laboratory tests, and engineering analysis, as well as geotechnically related recommendations for the proposed site development in the west portion of the property. • The purpose and scope of our study was outlined in our proposal March 10, 1997. Our work on this site covered the entire site bounded by Southwest 19th Street, Lind Avenue, the existing Boeing Office buildings and East Valley road. For the final work product, the site was divided into four separate parcels and corresponding reports. Each report contains the subsurface exploration and recommendations specific to that portion of the site. Based on the subsurface conditions encountered in the west portion of the subject site, it is our opinion that the proposed structure may be supported by augercast piles. The floor slab • may be supported by one foot of structural fill after successful completion of a surcharge program, provided the recommendations contained in this report are incorporated into the project design and specifications.

The site is bounded by a vacant portions of the parcel on the east, by Southwest 19th Street to the south, by Lind Avenue Southwest to the west and by existing Boeing office buildings to the north. At present, the site is vacant with grasses covering the existing surface. The site is generally level with several drainage ditches across the site. Subsurface The site was explored by drilling two borings and excavating five test pits at the approximate locations shown on Plate 2. As requested, we performed a subsurface exploration across the entire site between Southwest 19th Street, Lind Avenue Southwest, East Valley Road and the Boeing Office complex. Borings and test pits were numbered sequentially; however, each report contains only those logs that were documented -on the appropriate parcel. Detailed descriptions of the conditions encountered at each location explored are presented on the boring logs, Plates A2 through A7, and the test pit logs, Plates A8 through Al2. A description of the field exploration methods is included in Appendix A. Below is a generalized description of the subsurface conditions encountered. During our subsurface exploration, we observed up to ten feet of fill consisting primarily of silty sand (Unified Soil Classification SM) with concrete' rubble throughout. Concrete rubble ranged in size from gravel size up to slabs about three to four feet wide. Underlying the fill, the native soil consisted of peat interlayered with organic silt (OH) with moisture contents ranging from 51 to 151 percent in the peat and silt in the vicinity of the building. The peat and silt was observed to be soft to medium stiff. Beneath the peat between fourteen and sixteen feet beneath the existing ground surface, our borings encountered dark gray poorly graded sand with silt (SP-SM) and silty sand (SM) in a loose to medium dense condition. Based on the boring logs, the sand locally grades into gravel at about forty-five feet. At about twenty-five feet, the sand becomes dense to very dense. Earth Consultants, Inc.

The entire rectangular parcel covers about fourteen and one-half acres; however-this report covers only the west four and one-half acres. The site is bounded by a vacant portions of the parcel on the east, by Southwest 19th Street to the south, by Lind Avenue Southwest to the west and by existing Boeing office buildings to the north. At present, the site is vacant with grasses covering the existing surface. The site is generally Ir % level with several drainage ditches across the site. . Subsurface The site was explored by drilling two borings and excavating five test pits at the approximate locations shown on Plate 2. As requested, we performed a subsurface exploration across the entire site between Southwest 19th Street, Lind Avenue Southwest, East Valley Road and the Boeing Office complex.

Detailed descriptions of the conditions encountered at each location explored are presented 1 on the boring logs, Plates A2 through A7, and the test pit logs, Plates A8 through Al2. A description of the field exploration methods is included in Appendix A. Below is a generalized 1 description of the subsurface conditions encountered. During our subsurface exploration, we observed up to ten feet of fill consisting primarily of silty sand (Unified Soil Classification SM) with concrete rubble throughout. Concrete rubble ranged in size from gravel size up to slabs about three to four feet wide. Underlying the fill, the native soil consisted of peat interlayered with organic silt (OH) with moisture contents ranging from 51 to 151 percent in the peat and silt in the vicinity of the building. The peat and silt was observed to be soft to medium stiff. Beneath the peat between fourteen and sixteen feet beneath the existing ground surface, our borings encountered dark gray poorly graded sand with silt (SP-SM) and silty sand (SM) in a loose to medium dense condition. Based on the boring logs, the sand locally grades into gravel at about forty-five feet. At about twenty-five feet, the sand becomes dense to very dense. Earth Consultants, Inc. , • GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1B April 15, 1997 Page 3 Groundwater . Groundwater seepage was encountered in Test.Pit TP-9 .at a depth of seven and one-half feet. The groundwater table was encountered in the sand beneath the peat and silt between fourteen and sixteen feet beneath the existing grades. It is important to note that groundwater seepage is not constant; thus, one may expect fluctuations in the volume and location depending on the season, amount of rainfall, surface water runoff, tidal influence, and other factors. Generally, groundwater seepage is greater during the wetter winter months (typically October through May). Laboratory Testing Laboratory tests were conducted on several representative soil samples to verify or modify the field soil classification of the units encountered and to evaluate the general physical properties and engineering characteristics of the soils encountered. Visual classifications were supplemented by index tests, such as sieve analyses and Atterberg. Limits, and moisture content tests on representative samples. The results of laboratory tests performed on specific samples are provided either at the appropriate sample depth on the individual test pit log or on a separate data sheet contained in Appendix B. However, it is important to note that these test results may not accurately represent the overall in-situ soil conditions; our geotechnical recommendations are based on our interpretation of these test results. The soil samples for this project will be discarded after a period of fifteen (15) days following • completion of this report, unless we are otherwise directed in writing. . DISCUSSION AND RECOMMENDATIONS General 47, Based on the results of our study, it is our opinion that the proposed structure should be • supported by piles obtaining support in the dense sand and gravel underlying the site at a • depth of about thirty feet. The floor slab may be supported by one foot of structural fill after !_ successful completion of a surcharge program. The purpose of the surcharge program is to pre-induce most of the settlement estimated to result from building loads. The surcharge program should have.a minimum height of three feet above finished floor elevations. We anticipate completion of the surcharge in about eight to twelve weeks. Earth Consultants, Inc.

No warranty is expressed or implied. It is recommended that this report, in its entirety, be included in the project contract documents for the information of the contractor. Site Preparation and Grading • Construction areas should be stripped and cleared of existing vegetation, topsoil, organic debris, and other deleterious materials. Stripped organic materials should not be mixed with - soils to be used as structural fill. Following the stripping and clearing procedures, the earthwork operations can commence to provide the design grades. The ground surface where structural fill is to be placed should be proofrolled. Proofrolling should be performed under the - observation of a representative of ECI. Soil in any loose or soft areas, if recompacted and still excessively yielding, should be overexcavated and replaced with structural fill to a depth that will provide a stable base beneath the general structural fill or suitable support for slabs. The soils exposed in our test pits are moisture sensitive due to their high fines content. As such, in an exposed condition they will become disturbed from normal construction activity especially when in a wet or saturated condition. Once disturbed, in a wet condition, they will be unsuitable for support of foundations or pavements. Therefore, during construction where these soils are exposed and will support new structures, care must be exercised not to disturb - their condition. If disturbed conditions develop, the affected soils must be removed and replaced with a structural fill. The depth of removal will be dependent on the level of disturbance developed during construction. . Structural fill is defined as any compacted fill placed under foundations, roadways, slabs, pavements, or any other load-bearing-areas. Structural fill under foundations should be placed in horizontal lifts not exceeding twelve (12) inches in loose thickness and compacted to a minimum 95 percent of its maximum dry density in accordance with ASTM Test Designation D-1557 (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. j Soils expected to be exposed in excavations is silty sand and sandy silt. Due to the high fines content and natural moisture, it is our opinion this soil would not be suitable for use as. a structural fill in its present condition. Unless the moisture content can be lowered to near the optimum, native soil excavated from the cut area should either be removed from the site or used in non-structural areas. Earth Consultants, Inc. i , GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1B April 15, 1997 Page 5 Structural fill which is to be placed in wet weather should consist of a granular material with - a maximum size of three inches and no more than five percent fines passing the No. 200 sieve, based ,on the minus 3/4-inch fraction. During dry weather, most compactible non- ! organic soil can be used as structural fill. It is recommended that any structural fill planned for on-site use be submitted for approval prior to import. Surcharge Program The surcharge program is designed to pre-consolidate the compressible fills and soil underlying • the site, such that the surcharge would apply loads greater than anticipated building loads. The surcharge fill is in addition to the fill required to bring the site to grade. The surcharge should extend at least five feet beyond the perimeter of the buildings. The height of the surcharge should be three feet above finish floor. The side slopes of the fill should not be inclined any steeper than 1 H:1 V. If a wet weather construction schedule is planned, the surcharge fill should meet the requirements of a wet weather fill as discussed in the Site Preparation and Grading section of this study. The surcharge should be compacted to a density of one hundred twenty (120) pcf. The settlement of the surcharge should be about three to six inches. A smaller settlement should be interpreted as that the soils have been preconsolidated and soil conditions are better than anticipated. Conversely, a larger settlement could be interpreted that the soil conditions . are worse than anticipated, and that additional time and measurements should be taken to obtain satisfactory results. However, the only reasonably accurate means of verifying the settlement magnitude is to perform a monitoring program. The settlement monitoring program should include setting settlement monitors on the existing site subgrade before fill is placed, monitoring them through completion of fill placement, continuing until settlements cease or are considered within the buildings tolerable limits. More specific details of this program are presented below: • Settlement markers should be placed on the native subgrade of each building_ pad before any fill is placed-. A total of nine markers should, be installed within the building footprint. ECI can supply and install these markers. (A typical detail is provided on Plate 3). • A baseline reading is obtained on each marker and is referenced to a temporary benchmark located on a feature that will not be affected by the fill-induced settlements. • The fills are then placed. Settlement readings are taken at relatively short intervals during this process, since this phase generates relatively large and rapid settlement. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services _ E-7608-1 B April 15, 1997 Page 6 • Once the fill operation is complete, readings are obtained on a periodic basis, typically weekly, until the settlement ceases or the anticipated future settlements are judged by the geotechnical engineer to be about one inch. • Each set of settlement readings are plotted graphically against time to determine.the ' magnitude and rate of settlement, and are matched against the predicted magnitudes and rates to verify the accuracy of earlier estimates and to make any appropriate modifications. ECI should be retained to acquire the settlement readings. If you prefer to use another organization to collect these readings, measurements should be provided to us as quickly after their acquisition as possible for plotting and interpretation. This will help avoid any • misinterpretation or misunderstanding regarding the success of the surcharge program. The integrity of the settlement monitoring program must be maintained. In our experience, earthwork equipment (dozers, rollers, trucks, etc.) often demolish markers at.a very high rate. This adds to the project costs in that they need to be replaced and it makes the information obtained less reliable. To avoid this scenario, it is suggested that the project specifications include a requirement that the earthwork contractor is required to immediately replace any damaged settlement marker and have the settlement readings reobtained at his own cost. This requirement makes the.earthwork contractor more 'conscious of the importance of the preload program and will aid in maintaining the integrity of the monitoring program. Fill for landscaping purposes should not be placed near the building since additional fill could induce further settlements after the building is constructed. If such fill is planned, the surcharge should be extended to five feet beyond the planned landscape fill, or a lightweight fill, such as "hog fuel" be used. Foundations Based on the encountered subsurface conditions, we recommend the building be supported by piles bearing on the dense sand and gravel underlying the site at a depth of about twenty- five feet. We recommend the use of augercast piles in order to provide higher axial capacities; however, concrete volumes on the order of 150 to 175 percent of the theoretical volume can be expected due to the peat. Driven piles can be considered; however, driven timber piles will not be able to provide the higher axial capacities due to limitations during driving. We have j provided allowable axial, uplift, and lateral pile capacities for sixteen (16) and eighteen (18) inch diameter augercast piles. We would be available to provide load capacities for other pile sizes or lengths of embedment if needed. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY -- Southwest 19th Lind LLC • Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1B April 15, 1997 Page 7 • Augercast piles should extend into the dense sand .underlying the site with a minimum embedment of five feet. In our opinion, sixteen (16) inch diameter piles meeting this criteria can be designed for an allowable axial capacity of fifty (50) tons and an uplift capacity of twenty-five (25) tons. For an eighteen (18) inch diameter pile meeting the same criteria, an allowable axial capacity of fifty-seven (57) tons and an uplift capacity of fourteen (14) tons may be used for design. These capacities may be increased by one-third for short-term seismic loading conditions. No reduction in pile capacity is required if the piles are installed on a center-to-center spacing of three pile diameters. Lateral pile capacity is generally governed by deflections at the top of the pile which is dependent on pile stiffness with respect to the surrounding soil conditions in the upper portion { of the pile, the pile length, and degree of fixity at the top of the pile. In our opinion, a lateral pile capacity of five kips may be used for design for either diameter pile. Given a five kip lateral load, maximum pile deflections are estimated to be 0.25 inches. The passive resistance of soil against grade beams can also be used to resist lateral forces. If sufficient lateral resistance cannot be achieved by these means; batter piles may be used. If batter piles are necessary, ECI should be contacted to provide additional recommendations for maximum batter and lateral capacity. We estimate total settlement of single augercast piles will be on the order of 0.25 inches. We anticipate 80 percent of this settlement will during construction, as the dead loads are applied. The remaining settlement should occur within six weeks of construction completion. We estimate differential settlements should be less than 0.125 inches. The piles should be installed with a continuous-flight hollow stem auger equipment specifically designed for installation of auger placed grout-injected piles. Each pile should be drilled and completely fill with grout in an uninterrupted operation. The grout should be placed under a pressure of two hundred (200) psi in order to ensure adequate bonding with the bearing soils. A positive grout head of at least ten feet should be maintained at all time to prevent caving and voids. This can be accomplished by directing the contractor. to slow up the auger withdrawal rate such that a column of grout extends at least ten feet above the auger tip. �. As it is not possible to observe the completed pile below the ground, judgement and experience must be used as the basis for determining the acceptability of a pile. Therefore, all piles should be installed under the full-time observation of a representative of ECI. This will allow us to evaluate fully the contractor's operation, collect and interpreted the installation data, and verify bearing stratum elevations. Furthermore, we will also understand the implications of variations from normal procedures with respect to the design criteria. The contractor's equipment and procedures should be reviewed by 'ECI before the start of construction. Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1B April 15, 1997 Page 8 Seismic Design Considerations The Puget Sound region is classified as a Seismic Zone 3 by the Uniform Building Code (UBC). The largest earthquakes in the Puget Sound region have been subcrustal events, ranging in depth from 50 to 70 kilometers. Such deep events have exhibited no surface faulting. The UBC earthquake regulations contain a static force procedure and a dynamic force procedure for design base shear calculations. Based on the encountered soil conditions, it is our opinion that a site coefficient of 1 .5 should be used for the static force procedure, as outlined in Section 1628 of the 1994 UBC. For the dynamic force procedure outline in Section 1629 of the 1994 UBC, the curve for Soft to Medium Clays and Sands (Soil Type 3) should be used on Figure 16-3, Normalized Response Spectra Shapes. Liquefaction is a phenomenon in which soils lose all shear strength for short periods of time during an earthquake. The effects of liquefaction may be large total and/or differential q settlement for structures with foundations founded in the liquefying soils. Groundshaking of sufficient duration results in the loss of grain to grain contact and rapid increase in pore water pressure, causing the soil to behave as a fluid for short periods of time. To have potential for liquefaction, a soil must be cohesionless with a grain size distribution of a specified range (generally sands and silt); it must be loose to medium-dense; it must be below the groundwater table; and it must be subject to sufficient magnitude and duration of groundshaking. Based on the subsurface information obtained during our field exploration, it is our opinion that the liquefaction potential at the site is moderate due to the relative density of .the soils encountered and cohesive nature of the encountered silts. Should liquefaction occur, it will not be wide spread across the site and settlement due to liquefaction is estimated to be within the range provided in the Foundations section of this report. Lateral Resistance An allowable passive pressure value-against the sides of foundation slabs or other subsurface _ foundation elements of three hundred (300) psf per foot of depth may be used for design. In order to fully mobilize the passive pressure, the foundations must be poured "neat" against the adjacent soil or the foundation excavation must be backfilled with structural fill. Friction between the base of foundations and the underlying soil may be assumed to be 40 percent of the dead load. The friction and passive pressure design values include a factor-of-safety of 1 .5. Earth Consultants, Inc. . S + GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC • Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1B April 15, 1997 Page 9 -- I Floor Slabs After successful completion of a surcharge program, the floor slab may be supported by a minimum one foot of structural fill. Should loose soil be present at the slab subgrade. elevation, it should be compacted to the requirements of structural fill. Disturbed subgrade soil must either be re-compacted or replaced with structural fill. Post-construction settlement of the floor slab is estimated to be on the order of one inch provided a surcharge program is successfully completed. If one inch of settlement cannot be tolerated, then we recommend structurally supporting the floor slab. The slab should be provided with a minimum of four inches of free-draining sand or gravel. In areas where slab moisture is undesirable, a vapor barrier such as a 6-mil plastic membrane may be placed beneath the slab. Two inches of damp sand may be placed over the membrane for protection during construction and to aid in curing of the concrete. - I Excavations and Slopes In no case should excavation slopes be greater than the limits specified in local, state and federal safety regulations. As described in the current Occupational Safety and Health Administration (OSHA) regulations, the existing fill, sandy silt and poorly graded sands would classify as Type "C." Therefore temporary cuts greater than four feet in height, should be sloped at an inclination no steeper than 1 H:1 V in the Type "C" soils. If slopes of this inclination, or flatter, cannot be constructed, or if excavations greater than twenty (20) feet I in depth are required, temporary shoring may be necessary. This shoring would help protect against slope or excavation collapse, and would provide protection to workmen in the excavation. If temporary shoring is required, we will be available to provide shoring design • criteria, if requested. We understand that no permanent slopes are planned for the site; however, permanent slopes should be inclined no steeper than 2H:1V. Earth Consultants, Inc. should be requested to observe any permanent slopes to confirm the soil conditions and provide recommendations to improve the stability of the slope should it be necessary. • • The above information has been provided solely as a service to our client.

Earth Consultants, Inc. 1 • GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1 B April 15, 1997 Page 10 Site Drainage Groundwater seepage was encountered in Test Pit TP-1 at a depth of six and-one-half feet. The groundwater table was encountered in the borings in the sand beneath the peat and silt _ at thirteen and fifteen feet. It is possible that groundwater levels will present-construction related problems while making j excavations. Should groundwater seepage be encountered during construction, the bottom of the excavation should be sloped to one or more shallow sump pits. The collected water can then be pumped from these pits to a positive and permanent discharge, such as a nearby storm drain. Depending on the magnitude of such seepage, it may also be necessary to _ interconnect the sump pits by a system of connector trenches. It is recommended that the appropriate locations of subsurface drains, if needed, be established during grading operations by this office, at which time the seepage areas, if present, may be more clearly defined. The site should be graded such that surface water is directed off the site. Water should not be allowed to stand in any area where structures, slabs or driveways are to be constructed. During construction, loose surfaces should be sealed at night by compacting the surface to -reduce the potential for moisture infiltration into the soils. Final site grades should allow for drainage away from the structure foundations. The ground should be sloped at a gradient of three percent for a distance of at least ten feet away from the structures in landscape areas. This gradient may be reduced to two percent in paved areas. Foundation drains should be installed where landscaped areas are immediately adjacent to the. building. In our opinion, foundation drains are not necessary in areas where pavements extend to the building walls. -The drains should be installed at or just below the bottom of the footing, with a gradient sufficient to initiate flow. A typical detail is provided on Plate 4. Utility Support and Backfill - i Based on the soil conditions encountered, the majority of soils expected to be exposed by utility excavations should provide adequate support for utilities; however, deeper utility trenches may encounter the peat that is beneath the- existing fills. Should the peat, or soft soils, be exposed near pipe grades, the peat should be removed to a depth that will provide adequate support for the utility. - • • Earth Consultants, Inc. GEOTECHNICAL ENGINEERING STUDY Southwest 19th Lind LLC Continental Mills, Inc. c/o Martin Smith Real Estate Services E-7608-1 B April 15, 1997 Page 11 Utility trench backfill is a' major concern in limiting the potential for settlement along utility . alignments, particularly in pavement areas. It is important that each section of utility line be adequately supported in the bedding material. The material should be hand tamped to ensure support is provided around the pipe haunches. Fill should be carefully placed and hand tamped to about twelve (12) inches above the crown of the pipe before any heavy. compaction equipment is•brought into use. The remainder of the trench backfill should be placed in lifts having a loose thickness of less than twelve (12) inches. A typical trench backfill section and compaction requirements for load supporting and non-load supporting areas is presented on Plate 5. _ I Pavement Areas The adequacy of site pavements is related in part to the condition of the underlying subgrade. To provide a properly prepared subgrade for pavements, we recommend the subgrade be treated and prepared as described in the Site Preparation and Grading section of this report. This means at least the top twelve (12) inches of the subgrade should be compacted to 95 percent of the maximum dry density (per ASTM 1557). It is possible that some localized. areas of soft, wet or unstable subgrade may still exist after this process. Therefore, a greater thickness of structural fill or crushed rock may be needed to stabilize these localized areas. We recommend the following pavement section for lightly loaded areas: • . Two inches of asphalt concrete (AC) over four inches of crushed rock base (CRB) material, or • • -Two inches of AC over three inches of asphalt treated base (ATB) material. Heavier truck-traffic areas will require thicker sections depending upon site usage, pavement life and site traffic. As a general rule, you may consider for truck-trafficked areas the ,I -, j following sections: • Three inches of AC over six inches of CRB, or • Three inches of AC over four inches of ATB. Asphalt concrete (AC), asphalt treated base.(ATB), and crushed rock base (CRB) materials should conform to WSDOT specifications. All rock base should be compacted to at least 95 percent of the ASTM D-15,57-78 laboratory test standard. It should be noted that parking stall pavement sections assume no truck traffic. In addition, the above pavement sections are based on a 10-year design period.

Subsurface conditions at the site were explored by drilling two borings to a maximum depth of fifty-one and one-half (51 .5) feet below existing grade and excavating five test pits to depths of fourteen to sixteen . feet beneath the existing grades. • Approximate boring and test pit locations were determined by pacing from approximate property corners. The exploratory locations should be considered accurate only to the degree implied by the method used. These approximate locations are shown on the Boring and Test Pit Location Plan, Plate 2. The field exploration was continuously monitored by an engineer from our firm who classified the soils encountered and maintained a log of each boring, measured groundwater levels, and observed pertinent site features. All samples were visually classified in accordance with the Unified Soil Classification System which is presented on Plate Al, Legend. Borings The borings were drilled by Associated Drilling using a truck mounted drill rig. Continuous- flight, hollow-stem augers were used to advance and support the boreholes during sampling.' Logs of the borings are presented in the Appendix on Plates A2 through A7. 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 r boundaries between soil types. In actuality, the transitions may be more gradual. •In each boring, Standard Penetration Tests (SPT) were performed at selected intervals in general accordance with ASTM Test Designation D-1586. The split spoon samples were driven with a one hundred forty (140) pound hammer freely falling thirty (30) inches: The number of blows required to drive the last twelve (12) inches of penetration are called the "N- value". This value helps to characterize the site soils and is used in our engineering analyses. • Representative soil samples were placed in closed containers and returned to our laboratory for further examination and testing.• . • Earth Consultants, Inc. • APPENDIX A, Continued E-7608-1 B _ FIELD EXPLORATION Test Pits - Test pits were excavated by Northwest Excavating using a track-mounted excavator. Logs of the test pits are presented on Plates A8 through Al2. The final logs represent our interpretations of the field logs and the results of the laboratory tests on field samples.

J Il4 N 1 /i 1997 1 EXPIRES 4/3/4 I LPN ArCi .:tects Planners DOWNSTREAM DRAINAGE ANALYSIS Storm drainage runoff from the project sheetflows from north to south and is collected at two low points along the south property line by two existing catch basins. These two catch basins are located behind the road improvement and collect runoff from the existing site. The catch basins are protected by a silt fence buffer and discharge runoff to the existing 60-inch diameter storm tightline system along S.W. 19th Street. The existing 60-inch diameter tightline system along S.W. 19th Street travels westerly toward the intersection of S.W. 19th Street and Lind Avenue S.W. From the intersection of S.W. 19th Street and Lind Avenue S.W., the 60-inch storm drain travels due west approximately 1,100 lineal feet in a 60-inch reinforced concrete pipe system. It discharges at this point into a well defined 6- to 10-foot deep vegetated ditch that appears to be approximately 5 feet wide with 2 to 1 side slopes. At a point approximately 200 feet west, the flow enters a 60-inch corrugated metal pipe which conveys the drainage due westward approximately 100 feet into Springbrook Creek where it is discharged. i . 6045r.001 i 1 1 • • ' ,n'31TM :wr..

SOILS SURVEY MAP 1.0 INTRODUCTION/GENERAL INFORMATION The proposed nine-lot short plat is located in Section 19, Township 23, Range 5 East, Willamette Meridian, in the City of Renton, Washington. The site is bound by Lind Avenue S.W. to the west, S.W. 19th Street to the south, East Valley Road to the east, and existing office buildings to the north. The rectangular site is approximately 14.5 acres. 2.0 EXISTING SITE CONDITIONS The King County Soil Classification Guide shows the site to have a mixture of soil types. The survey indicates the site consists of the Puyallup soil group, which is a hydrologic Group B, and an urban soil group, which is a variable hydrologic group. However, this survey was done prior to the site being filled with several feet of imported material. Our site investigation reveals that the on-site soils probably are a hydrologic Group C. The site is almost fully grassed and contains small areas of light brush, but no significant trees. The topography is very flat. Some small depressions exist due to previous inconsistent fill placement. The site sits higher relative to its surroundings and, therefore, receives no off-site drainage. 3.0 DOWNSTREAM DRAINAGE ANALYSIS Storm drainage runoff from the project sheetflows from north to south and is collected at two low points along the south property line by two existing catch basins. These two catch basins are located behind the road improvement and collect runoff from the existing site. The catch basins are protected by a silt fence buffer and discharge runoff to the existing 60-inch diameter storm tightline system along S.W. 19th Street. The existing 60-inch diameter tightline system along S.W. 19th Street travels westerly toward the intersection of S.W. 19th Street and Lind Avenue S.W. (87th Avenue South). From the intersection of S.W. 19th Street and Lind Avenue S.W., the 60-inch storm drain travels due west approximately 1,100 lineal feet in a 60-inch reinforced concrete pipe system. It discharges at this point into a well defined 6-to 10-foot deep vegetated ditch that appears to be approximately 5 feet wide with 2 to 1 side slopes. At a point approximately 200 feet west, the flow enters a 60-inch corrugated metal pipe which conveys the drainage due westward approximately 100 feet into Springbrook Creek where it is discharged. 4.0 ON-SITE DRAINAGE CONSIDERATIONS The proposed short plat will contain one drainage/detention system for the entire project. Drainage from the site will be discharged into the existing wetland across S.W. 19th Street to the south of the site, which ultimately flows into the previously mentioned 60-inch storm drainage system in S.W. 19th Street. The wetland will be used for peak rate runoff control. In addition, a wet/detention vault located on the south property line of the site will also be used for some detention. This system is described in greater detail in the following paragraphs. All site storm drainage detention and water quality systems will meet City code and be in accordance with City standard systems or equivalent systems. 6045.001 [KLIes] Storm drainage construction for the first phase of the project will consist of the construction of the wet/detention vault and outfall, as well as the storm drainage conveyance system which will provide stubs to each individual lot. When the individual lots are developed, their storm drainage systems can then tie into the provided stubs. Water quality for the entire project will be provided in the wet/detention vault located along the south property line of the site. The vault is designed using the February 1996 draft of the King County Surface Water Design Manual, which is a method of analysis based on computer modeling using the King County Runoff Time Series (KCRTS) model. The City of Renton requires the wetpond to be 1.5 to 2 times the design surface area and volume as calculated using the 1990 KCSWDM Design Standards if a biofiltration swale does not precede it. Using the KCRTS method of design, the vault is approximately 1.8 times the surface area and 2.7 times the volume requirements of the 1990 KCSWDM. The wetpond design calculations are contained later in this report. The wetland on the property south of the project is approximately 10 acres in size. The developer proposes to use this wetland as one of his two means of peak rate runoff control and detention. Special requirement No. 8 of the King County Surface Water Design Manual specifies that the increased volume of runoff from the proposed project may not increase the 100-year floodplain elevation of a wetland more than 0.1 feet. Based on this requirement and the area of the wetland we have estimated, approximately 40,000 cubic feet of storage is available. Also contained in this report are the calculations for a standard detention system based on City of Renton requirements. These requirements require the developer to match the peak flows of the 2-and 10-year design storm events and increase the required storage volume by 30 percent above the 10-year design storm event. Based on a total build out of the project assuming 90 percent impervious area, the required storage volume would be approximately 60,000 cubic feet. The difference between volume required and volume provided by the wetland is 20,000 cubic feet. This difference must be detained on site. Based on the preliminary water quality calculations, the surface area required for the wet vault is approximately 10,400 square feet. Therefore, 2 feet of storage above the static water surface elevation of the wet vault will provide the necessary on-site storage to make up the 20,000-cubic foot difference. If it is determined that the wetland cannot provide the assumed storage, additional storage will be provided in the on-site wet/detention vault. The outlet control structures from this detention vault would then regulate flows to the wetland and possibly also to the existing 60-inch storm drain in S.W. 19th Avenue. An existing 24-inch pipe currently picks up wetland overflow and conveys it to the 60-inch pipe in S.W. 19th Avenue. Since additional drainage will be reaching the wetland from the site, a storm drainage manhole will be constructed on the existing 24-inch wetland outlet pipe that contains a flow control structure designed in accordance with special requirement No. 8 of KCSWDM. Please refer to the preliminary grading and storm drainage plans for the project for additional information on the storm drainage system. 6045.001 [KL/es] • 1 ', 4'O 1347H� sit/2rm Sr 1 < 18 ndr,wl=yw ,.., < " WAIT atm 7LYRYT ''.� I` H� a a �� i$ 2ND Hs .
