LUA()6-011, ECF, and LUA05-041, SA-A) Dear Ms. MacGregor-Crone, This letter is to inform you that we have approved your proposed revisions to the Renton Technical College site plan for the new maintenance/classroom building. The Site Plan for an 11,088 sq ft maintenance/classroom building was initially approved via an administrative Site Plan Review process on May 30, 2005 (LUA05-041). The current request seeks to move the location of the proposed. building approximately 200 ft northwest. The new location is partially within an area 'of steep slopes that were determined to be man-made, as indicated in the Exception Through Modification that. was issued by the Development Services Director on April 20,2006. A SEPA Determination of Non-Significance -Mitigated (DNS-M) for the proposed revision was issued on April 3, 2006. No other changes to the building design or use have been proposed. The Site Plan regulations define minor adjustments or modifications to an approved site plan as changes which do not iilVolve' more than a 10% increase in area or scale of the development, which do not have. a significantly greater .impact on theerivironment and facilities, and which do not change the boundaries of. the originally approved plan (RMC 4- 9-200.H.). The revisions. as proposed, appear to comply with the,applicable development standards. of the Industrial Low (Public) zone and applicable parking regulations. It has been determined that the revised proposed would not result in any significant environmental impacts above those analyzed under the previous development review. Therefore, the proposed modification to the site plan review is approved as a minor modification subject to the following conditions: • The applicant shall comply with all mitigation measures in the DNS-M issued April 3,2006. . The applicant is advised that all code requirements and conditions of the site plan approval, dated May 3D, 2005, remain applicable to the proposed development. If any further modifications are proposed in future, additional SEPA Review and Site Plan Review may be required.' This decision to approve the proposed revisions as a minor modification is subject to a 14- . day appeal period from the date of this letter.

LUA06-011, V-H, ECF Dear Ms. MacGregor-Crone: I have considered your request for an Exception Through Modification to allow development on a steep slope (greater than 40%) located at the north end of the RTC Campus. The proposal is for the' construction of an ' 11,088 sq ft maintenance/classroom, building in a~ . existing vacant area, which wiU .require approximately 2,600 cubic yards of grading and 600 cubic yards of fill. Access will be from internal roads and parking will be accommodated within existing parking lots .. Renton Municipal Code Section 4-3-050J.5.b provides for Exception~ through Modification to address steep slopes .. The applicant maintains that the steep slope area in question was created by previoLis grading and fill activities required to construct an internal access road and'parking lot located west of the site, and a classroom building to the east of the site, which resulted in an artificial grade line for this area. The City's Environmental Review Committee has reviewed the geotechnical report and supplemental information submitted' with .the project application, and imposed, a mitigation meaSUie requiring the applicant to comply with' all recomme~dations included in the report. This mitigation measure is still effective and the project must be constructed in compliance with this reqLiirement. Decision Based on the information provided by the applicant, it is my determination that the steep slope located in the area proposed for the classroom/maintenance building qualifies for an Exception through Modification, per RMC Section 4-3-050.J.5.b. Therefore, gra'ding activities may be permitted on the slope identified in the project application, with the benefit of the' applicable permits and land use approvals. Although the slope qualifies for an, Exception through 'Modification, additional approvals and permits from the City will be required, including an administrative -------10-S-S -So-u-Ih-G-r-ad-y-W-a-y---R-en-\o-n-, W-.s-h-in-gt-on-9-S0-S-S ,--'-----~ (ll() This paper contains 50% recvded material. 30% post consumer AHEA[) OF THE CURVE Sally MacGregor-Crone tiil .

PARKING LOT (SITE PLAN & VARIANCE) EnvJ. .:~,\taf Review Committee Staff Report LUA-04-093 AND LUA05-133 ERC REPORT of February 21, 2006 Page 2 of 3 PROJECT DESCRIPTION CONTINUED: A site plan for the proposed building received final approval on May 30, 2005 (LUA05-041), for a location approxinmately 200 ft southeast of the current proposal which would not have impacted any critical areas. An environmental (SEPA) review was conducted for that proposal and a Determination of Non-Significance -Mitigated (DNS-M) was issued concurrently with the administrative decision to approve the site development plan. The applicant's current proposal to shift the building approximately 200 ft to the northwest of the original location into an area of protected slopes would be considered a minor modification to the site development plan, subject to approval of a variance from the City's Critical Areas Regulations. No other changes to the building design or use have been proposed. The variance request qualifies for review under RMC 4-9-250B.10 (Special Review Criteria -Public/Quasi-Public Utility or Agency), and must be heard by the City Hearing Examiner. The variance request triggers the requirement for environmental review because of proposed impacts to critical areas (protected slopes). Because an environmental review was conducted for the original site plan, the environmental review for the variance request will address only the issue of the new building location. The mitigation conditions for Water, Transportation, and Fire/Emergency Services in the DNS-M issued on May 16, 2005 do not require modification and will remain binding upon the updated site plan proposal. B. RECOMMENDA TlON Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials make the following Environmental Determination: DETERMINA TlON OF NON-SIGNIFICANCE Issue DNS with 14 day Appeal Period. C. MITIGA TION MEASURES DETERMINA TlON OF NON -SIGNIFICANCE -MITIGATED. XX Issue DNS-M with 14 day Appeal Period. Issue DNS-M with 15 day Comment Period followed by a 14 day Appeal Period. 1. The applicant shall comply with Mitigation Measures 1 (Earth), 2 (Transportation), and 4 (Fire/Emergency Services) of the DNS-M for LUA05-041, issued on May 16, 2005. Mitigation Measure 2 (Earth) of the DNS-M for LUA05-041 is superseded by Mitigation Measure 2 of the DNS- M for LUA06-011 as provided below. 2. The applicant shall comply with the recommendations contained in the geotechnical report prepared dated October 13, 2005, and a supplemental report dated February 28, 2006, prepared by Associated Earth SCiences, Inc., regarding site preparation, foundation construction, landslide and erosion prevention, and drainage measures, in order to mitigate potential impacts to the soils and surrounding properties in the areas of steep slopes. All Advisory Notes in the DNS-M for LUA05-041, issued on May 16, 2005, continue to apply to the current development proposal. D. ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1.

PARKING LOT (SITE PLAN & VARIANCE) LUA-04-093 AND LUA05-133 ERG REPORT of February 21. 2006 Page 3 of 3 Impacts: The proposed location of the maintenance/classroom building is an area of moderate to steep (>40%) grass-covered slopes at the north end of the RTC campus. According to the applicant, approximately 2,600 cubic yards (cu yd) of grading will occur, and 600 cu yd of fill. It is estimated that approximately 50% of the grading will occur on protected steep slope areas. The site is indicated on the City's Critical Areas Map as a Moderate Landslide Hazard. The applicant submitted a geotechnical report prepared dated October 13, 2005, and a supplemental report dated February 28, 2006, prepared by Associated Earth Sciences, Inc. According to the report, one exploration boring and pit were conducted, as well as infiltration testing and geologic hazard reconnaissance. Fill soils were encountered to a depth of approximately 2 feet, and generally consisted of a loose mixture of silt and sand considered unsuitable for support of the proposed structure. The fill soils may be considered for use as structural fill where moisture-conditioned and compacted as recommended in the geotechnical report. Below the fill, the soil was classified as Vashon recessional outwash, Alderwood gravelly sandy loam. Site soils are considered to have a low possibility for liquefaction. The slope areas appear to be somewhat susceptible to a shallow debris flow, due to the presence of the outwash-type soils located below the fill; however, these slopes are proposed to be removed as part of the development proposal. The risk of shallow earth movement on the site or surrounding properties is not considered to be increased by the development proposal. The report notes that the onsite soils are considered moisture-sensitive, and all permanent and temporary slopes should be protected from erosion. Staff recommends that the applicant comply with all recommendations provided by the applicant's consultant regarding site preparation, foundation construction, landslide and erosion prevention, and drainage measures, in order to mitigate potential impacts to the site including areas of steep slopes. Mitigation Measures: The applicant shall comply with the recommendations contained in the geotechnical report prepared dated October 13, 2005, and a supplemental report dated February 28, 2006, prepared by Associated Earth Sciences, Inc., regarding site preparation, foundation construction, landslide and erosion prevention, and drainage measures, in order to mitigate potential impacts to the site including areas of steep slopes. Policy Nexus: SEPA Environmental Regulations. E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental/Divisional Reviewers for their review. Where applicable, these comments have been incorporated into the text of this report as Mitigation Measures and/or Notes to Applicant. ~ Copies of alJ Review Comments are contained in the Official File. __ Copies of all Review Comments are attached to this report.

East of the site is campus parking and a 100-foot overhead power easement (PSP & L Co,), To the west lies an internal street then Building "L", The campus itself is located at the northwest corner of NE 4th Street and Monroe Avenue NE, covering approximately 30.6 acres, The building coverage percentage for the campus is 27.6%, Access to RTC is gained off of NE 4th and 7'h Streets, Kirkland Avenue NE and Monroe Avenue NE, Site improvement proposes to eliminate 10 parking spaces however the provided parking on the campus exceeds the required number of parking spaces, Eight trees are proposed to be removed, 6 Cherry and 2 Douglas Fir. A landscape plan has been submitted as part of the land use application, The site is located in the Cedar River Drainage Basin. The stormwater runoff will be handled per the 1990 King County Surface Water Drainage Manual (KCSWDM) and an on- site infiltration system will collect the surface water runoff, The site indicates Medium Landslide Hazard and has 25% slope defined as sensitive slope, The project requires environmental SEPA review and administrative site plan review. Upon completion, the project would generate total building lot coverage of less than 22% of the proposed site. The percentage of campus covered by buildings is 27,6%, The applicant anticipates project construction to commence in July of 2005 and be substantially completed by February of 2006 with an estimated construction cost of $2,300,000,00, II PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43,21C,240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmentat tmpacts The Proposal was circulated and reviewed by various City Depariments 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: (1) Earth Impacts: The proposed site is a moderate grass-covered slope descending from east to west, with approximately 20 to 25 percent slope. The applicant submitted a geotechnical report with the application prepared by Associated Earth Sciences, Inc, dated February 8, 2005. According to the report, one exploration boring and pit were conducted as well as performing infiltration testing and geologic hazard reconnaissance, Fill soils were encountered to a depth of approximately 1 to 2 feet and consisted generally of a loose mixture of silt and sand unsuitable for support of proposed structure. The fill soils may be considered for use as structural fill where moisture-conditioned and compacted as recommended in the geotechnical report. Generally the soil type is Alderwood, The site is indicated as a Moderate Landslide Hazard, Two types of landslides that commonly occur in the Puget Sound region are Earth Slump-Earth Flow and Debris Siump- Debris Flow, The proposed site seems to be more susceptible to a shallow debris flow due to the presence of the glacially consolidated, advance outwash soil below the fill layer. The geotechnical report determined the proposed development should not increase the risk of deep-seated movements provided the recommendations presented in the report are complied with, Therefore, staff recommends the applicant comply with the recommendations for site preparation, structural fill and foundation construction in order to mitigate potential construction impacts to the proposed structure. These recommendations discuss the ratio of temporary cut slope ratio and soil stabilization of disturbed area during site preparation and excavation, The proposal is to remove for site preparation, 4,090 cubic yards and fill 2,310 cubic yards, Potential erosion impacts that could occur during project construction would be adequately mitigated by City Code requirements and SEPA mitigation measures. In order to limit impacts to neighboring properties, staff recommends that the applicant be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed in accordance with the 2001 Department of Ecology Manual (DOE) and a Construction Mitigation Plan prior to issuance of Construction Permits. site&erc05-041.doc City of Renton PIB/PW Department -Ad 'stralive Site Plan Approval & Environmental F ',w Committee Staff Report RENTON TECHNICAL COLLEGE NEil> ALDING LUA-05-041, SA-A, ECF REPORT AND DECISION OF MAY 10,2005 Page 3 of 10 Mitigation Measures: 1. The applicant shall be required to provide a Temporary Erosion and Sedimentation Control Plan (TESCP) designed in accordance with the 2001 Department of Ecology Manual (DOE) and a Construction Mitigation Plan prior to issuance of Construction Permits. 2. The applicant shall comply with the recommendations contained in the geotechnical report prepared by Associated Earth Sciences, Inc. dated February 8, 2005 regarding site preparation and foundation construction in order to mitigate potential construction impacts to the proposed structure. Policy Nexus: SEPA Environmental Regulations; 2001 DOE Erosion Control Manual (2) Water Impacts: The applicant has submitted a Drainage Report prepared by Coughlin Porter Lundeen, dated March 2005 with the land use application. The report indicates that the storm water runoff sheet-flows to one collection point then discharges through a private storm system along the western edge of the campus. The system is routed to the 18-inch public storm main in Kirkland Avenue NE. The surface water generated by the new construction will be collected and routed to underground infiltration chambers. The drainage system has been designed in accordance with the 1990 King County Surface Water Design Manual (KCSWDM) for detention and water quality. Impervious area will cover approximately 0.34 acres of land. The 31-chamber infiltration system is designed to provide 2,693 cubic feet of storage volume. According to the drainage report, as less than one acre of new pollution-generating impervious surface is proposed, no water quality treatment is proposed to be provided for this project. However, prior to the issuance of construction permits for the installation of the stormwater system, staff will verify the proposed drainage facility is appropriately designed to accommodate stormwater runoff generated from the proposed development. Mitigation Measures: N/A. Nexus: N/A (3) Transportation Impacts: The traffic analysis was waived as a requirement of submittal for the proposed classroom/maintenance building. However, review conducted by staff the proposal is consistent with current City transportation policy and planned in a matter that is safe and efficient with existing traffic patterns in this area of the City. The proposed new structure is to consolidate existing uses on the college campus thus is not expected to generate additional traffic. Credit will be given for existing trips and portable structures. However, if the proposed maintenance/classroom facility does generate new traffic count, a Traffic Mitigation Fee of $75.00 per additional Average Daily Trip shall be assessed. Therefore, staff recommends that the applicant be required to pay the appropriate traffic mitigation fee. The Traffic Mitigation Fee is calculated at a rate of $75.00 per net new average daily trip associated with the project. Staff recommends that this fee be payable prior to the issuance of building permits. Mitigation Measures: The applicant shall pay the appropriate Traffic Mitigation Fee based on a rate of $75.00 for each new average weekday trip attributable to the project prior to the issuance of building permits. Credit will be given for existing trips. Policy Nexus: SEPA Environmental Regulations: Transportation Mitigation Fee Resolution No. 3100, Ordinance 4527 (4) Fire / Emergency Services Impacts: The proposal would create 11,088 square feet of new commercial building area, which would potentially impact the City's Fire Emergency Services. Therefore, staff recommends that the applicant be required to pay a Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area. The fee is estimated at $5,765.76 ($0.52 x 11,088 new building area = $3,949.40) and is payable prior to issuance of the building permits. Mitigation Measures: The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area prior to the issuance of building permits.

Consistency with Site Plan Criteria In reviewing the proposal with respect to the Site Plan Approval Criteria set forth in Section 4-9-200 of the Site Plan Ordinance, the following issues have been identified by City Departmental Reviewers and Divisional Reviewers: 1. Conformance with the comprehensive plan, its elements and policies; Comprehensive Plan, Its Elements and Policies site&erc05-041.doc The proposed site is designated Commercial Corridor (CC) on the City's Comprehensive Plan Land Use Map. The CC areas are characterized by concentrated, pre-existing commercial City of Renton PIBIPW Department -Ad ',trative Site Plan Approval & Environmental r,w Committee Staff Report RENTON TECHNICAL COLLEGE NEVI .JILDING WA-05-041, SA-A, ECF REPORT AND DECISION OF MAY 10. 2005 Page 5 of 10 activity. primarily in a linear urban form, that provided necessary goods and services for daily living, accessible to near-by neighborhoods, serving a sub-regional market and accommodating large volumes of traffic. The proposed educational use is consistent with the following CC policies: • Policy LU-349. Support development plans incorporating the following features: 1. Shared access points and fewer curb cuts; 2. Internal circulation among adjacent parcels; 3. Shared parking facilities; 4. Allowance for future transition to structured parking facilities; 5. Centralized signage; 6. Unified development concepts; and 7. Landscaping and streetscape that softens visual impacts. The proposed project will be accessed from existing access points and will not create any additional curb cuts. The existing internal circulation will not be altered by the development and while several parking spaces are to be removed, the existing number of required parking complies with code. • Policy LU-367. In areas developed with high intensity office uses, site and building design should be transit-, people-, and pedestrian-oriented. Ground floor uses and design should be pedestrian-oriented. While the proposed structure is two-stories, each floor is grade level and therefore pedestrian oriented. • Policy LU-74. Internal site circulation should be primarily pedestrian-oriented. The new structure is sited on a small-undeveloped area within the existing technical college campus. Parking area is located to the east of this proposed site however the campus as a whole is pedestrian-oriented. As proposed, the site layout and the proposed use generally comply with the policies and the intent of the Comprehensive Plan. 2. Conformance with existing land use regulations; The site is located within the Light Industrial (IL(P» zoning designation. The purpose of the IL zone is to provide for low-intensity manufacturing, industrial services, distribution, storage, and technical schools. The Public Use "P" suffix requires written notice to adjacent property owners if the following are proposed: a change of use; a change of the major tenant; and/or any change of ownership of the premises. As the propject will not change tenant, ownership or use, no written notice was required. The applicant, Renton Technical College, has proposed to construct an 11,088 square foot building that would be utilized as classroom/maintenance facility. In general, the proposal appears to be consistent with the range of uses permitted in the IL zoning designation, and does not propose any changes to the use, tenant or ownership of the site. Lot Coverage -The IL zone has maximum lot coverage for buildings of 65%. With the addition of the proposed building (11,088 sq It), the entire campus would generate building lot coverage of 27.6%. Setbacks -The IL zone requires a minimum front yard street setback of 15 feet. The IL zone also requires a minimum setback of 20 feet if abutting or adjacent to a residentially zoned property. In this case, the property is not adjacent to property designated residential on the City's Zoning Map; and is interior to the parcel. As proposed, the project complies with the required IL zoning setbacks prescribed by City code. Landscaping -Because the proposed site is interior to the technical college campus, the new building does not abut any public right of ways nor is it adjacent to any residential zoned property. The site is currently a grass slope with eight trees (6 deciduous and 2 fir) to be removed. The applicant has submitted a landscape plan as part of the land use application. site&erc05-041.doc City of Renton PIB/PW Department -Ad ',tralive Site Plan Approval & Environmental F '1W Committee Staff Report RENTON TECHNICAL COLLEGE NEV. ALDING LUA-05-041, SA-A, ECF REPORT AND OECISION OF MAY 10,2005 Page 6 of 10 The site is located between a parking area to the east and a private access lane to the west The grass areas to the north and south that are disturbed will be restored, The landscape plan will provide 7 River Birch, one Paperback Maple and 3 Hogan Western Red Cedar, In addition to grass lawn, the applicant proposes a variety of shrubs and flowers, An underground irrigation system is to be installed, The proposed landscape plan provides enhancement to the surrounding area of the proposed building and more than adequately compensates for loss of vegetation to this area of the campus, Height -The IL zone has a building height limit of 50 feet The applicant has proposed to construct a two- story building that would be approximately 34 feet in height above finished grade, Parking/Circulation -The parking regulations require a minimum of one parking stall per employee plus one for every 3 students residing on campus, plus one stall for every 5 day students not residing on campus. The campus does not provide on-site residence; therefore all students reside off campus thus requiring one stall for every 5 students. The number of students is 1,225 (1,225/5= 245). The number of RTC employees is 406 (406 x 1 = 406). Including ADA accessible stalls, the total number of stalls required is 672. The total number of parking stalls provided is 1,019 (973 standard and 46 ADA accessible). The 10 spaces will be removed by the proposed project and have been deducted. The site exceeds required on-site parking stalls. The access to the parking areas will not be altered. The parking regulations specify standard stall dimensions of 9 feet by 20 feet and compact stall dimensions of 8)1, feet by 16 feet Compact spaces are not allowed to exceed 30% of the required spaces and must be marked. An aisle width of 24 feet is required for 90 degree parking stalls, 20 feet is required for 60 degree parking stalls and 12 feet is required for 45 degree parking stalls. Stall lengths may also be reduced by 2 feet provided there is sufficient area to safely allow the overhang of a vehicle without protruding into required landscape areas. As proposed, the project would comply with the required number of on-site spaces for the established uses of the property. In addition, the project would comply with the minimum stall and aisle dimensions and amount of ADA and compact parking stalls requirements specified by the Parking Regulations. 3. Mitigation of impacts to surrounding properties and uses; The proposed building site is a sloped landscaped area internal to the Renton Technical College (RTC) campus. The two-story building is to serve as classroom and maintenance facility, each floor will have at grade access. The maintenance use is on the first floor with access from the west along the private drive. The second floor classrooms gain access from the parking lot to the east The new building is over 100 feet from the closest property line, which abuts Monroe Avenue NE. The proposed building will consolidate existing uses on the campus. The completion of the new space will allow the removal of three portable structures. Additionally, the applicant has proposed landscaping around the proposed new building. The landscaping includes several varieties of shrubs and trees as well as seasonal plantings. Exterior stairs will be maintained to the south of the new building to provide pedestrian connection from the lower western side of the campus to the upper parking area to the east 4. Mitigation of impacts of the proposed site plan to the site; The project has been designed to be a cohesive, well-planned construction on a densely developed campus. The site is providing ample on-site parking near the building entrance and circulation throughout the site. Pedestrian access will be discussed in the Safety and efficiency of vehicle and pedestrian circulation section of this report. The site layout has the structure organized such that the building takes advantage of the nature slope of the site. The 11,088 square foot building has been generally designed as a rectangular shaped building. The east elevation will appear as a one-story building visible from Monroe Avenue NE although over 100 feet away. An overhead 100-foot wide power easement lies between the proposed site and the eastern property line. This easement (PSP &L Co) runs the length of the Renton Technical College campus thus restricting the possible uses allowed in this area. Parking and access are currently located in the easement. Staff does not expect the proposal to adversely impact the site, as the applicant has a well-designed building placement, the two-story structure will have the appearance of one-story from the east elevation. The project has been designed to improve classroom facilities, remove eXisting portable structures and consolidate the maintenance facility. Once completed the proposed structure is to house the existing uses currently occupying the three portable structures on the campus thus to facilitate the removal of these temporary structure, staff recommends the following condition of site plan approval: the applicant shall be required to remove the three portable structures located at the south end of campus, east of Building A, which are to be replaced by the site&erc05-041.doc City of Renton P/B/PW Department -Ad ,trative Site Plan Approval & Environmental F 'W Committee Staff Report RENTON TECHNICAL COLLEGE NE'A ALDING LUA-05-041, SA-A, ECF REPORT AND DECISION OF MA Y 10, 2005 Page 7 of 10 new structure, Demolition permits shall be issued and final inspection completed prior to the issuance of the Certificate of Occupancy of the new structure. There are no known significant natural features within the project site, which would be impacted by the development. All construction activities would be required to utilize best management practices and adhere to the mitigation measures contained within the environmental SEPA review portion of this report, which would reduce potential construction impacts to the site. 5, Conservation of area-wide property values; The proposal would allow for an existing higher education institution to provide a new facility to better serve their students and staff. The applicant has proposed to construct an 11,088 square foot classroom/maintenance building. The project is estimated to cost $2,300,000,00 for construction, The project has been designed to be a cohesive development to the campus, providing improved landscaping and modern building construction. Specifically, the buildings have been designed to be two-story in height with on grade access for each floor. The new building will allow the removal of 3 portable structures currently on the campus, As such, staff expects the project to conserve or potentially enhance area-wide property values in this vicinity of the City. 6, Safety and efficiency of vehicle and pedestrian circulation; The proposed structure is located towards the northern end of the college campus with the closest accesses from Monroe Avenue NE and NE 7'h Street. The building design provides at-grade access to each floor. Access to the structure via the east elevation is towards a parking area and driveway; exterior stairs from the upper parking area to the lower campus link the south pedestrian access, A 26-foot wide access driveway runs along the western elevation of the structure and provides access to the two proposed vehicular storage bays of the maintenance facility, While the site plan provides for pedestrian access, via the exterior stairs to the south of the building connecting the western side of the campus (at a lower grade) to the parking area to the east of campus and sidewalks, the applicant fails to show pedestrian crosswalks to either the eastern parking area or connecting the stairs to sidewalk across the interior driveways. Therefore, in order to ensure safe pedestrian passage from the east parking area and connection from the southern stairs, staff recommends that striped pedestrian connections be installed which would ensure safe pedestrian maneuverability between the proposed eastern parking area and the building entrance and the stairs to the western portion of the campus, This condition shall be subject to the review and approval of the Development Services Division prior to the issuance of the building permit. 7, Provision of adequate light and air; As this site is internal to the campus thus over 100 feet from the property lines, staff does not expect any adverse impact to adjacent properties, Staff does not anticipate the blockage of light and/or air to the proposed site or to the surrounding properties. In fact, the building layout has been designed to utilize the existing slope of the site to give the two-story structure the appearance of one story from the east elevation. The structure is surrounded by landscape or parking/driveway providing space for air and light circulation, The two-story west elevation proposes a height of 34 feet with a slope roolline, As the building is proposed to be limited in height, staff does not expect the structures to cast significant shadows or block normal airflow within the site or on neighboring properties, The building has been designed to include large windows on all sides of the structure, which will also allow adequate light and air to circulate throughout the proposed building. There is existing site lighting for the exterior parking/security lights throughout the parking areas within the campus. Mitigation of noise, odors and other harmful or unhealthy conditions; The proposal is not expected to create any harmful or unhealthy conditions. Moreover, the proposed site is undeveloped except for stairs and a few parking stalls. The use would utilize a space on a campus otherwise developed and restricted by a 1 ~O-foot wide utility easement. The new building would facilitate the removal of three portable structures, which are in poor condition. An enclosed area at the northeast corner of the site is proposed to house the chiller, In addition, the applicant has proposed to provide landscaping surrounding the structure, which will help to minimize any visual and noise impacts associated with the use, As proposed, staff does not expect the use to create significant noise and odor impacts above existing conditions within this campus. Lastly, noise, dust and odor, which may result from the temporary construction of the site, would be mitigated by the applicant's construction mitigation plan and all project related conditions, site&erc05-041.doc City of Renton PIBIPW Department -Ad 'strative Site Plan Approval & Environmental F '9W Committee Staff Report RENTON TECHNICAL COLLEGE NElli ALDING LUA-05-041, SA-A, ECF REPORT AND DECISION OF MAY 10.2005 Page 8 of 10 8. Availability of public services and facilities to accommodate the proposed use; and The proposed site is adequately served by public services and facilities. The proposal would not require the extension of services or further improvements, provided all conditions of approval are met, advisory notes are adhered to and all fees paid. 9. Prevention of neighborhood deterioration and blight. As noted above, the proposed site is currently undeveloped and would ultimately be utilized for additional classroom and facility maintenance area. Staff expects the development of the site, including a new building, ample on-site parking and cohesive landscaping to be a benefit to the community and the existing neighborhood. Therefore, no deterioration or blight is expected to occur as a result of this proposal. xx Co ies of all Review Comments are contained in the Official File.

Bnilding -NE 4th and Monroe Ave NE NOTE ON PRELIMINARY REVIEW COMMENTS CONTAINED IN THIS MEMO: The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant. The applicant is cautioned that information contained In this summary may be subject to modification and/or concurrence by official decision makers (e.g. Hearing Examiner, Boards of Adjustment, Board of Public Works and City CouDcll). Review comments may also need to be revised based on site planning and other design cbanges required by the City or made by the applicant. The following comments concern utility and transportation development issues for the subject site: WATER I. There is an existing 8" water main looping the existing facilities. 2. The modeled fire-flow available at the site is approximately 2500 gpm. 3. The proposed project is located within the 565-water pressure zone. Static water pressure is approximately 90 psi. Pressure over 80 requires a pressure-reducing valve (PRV). 4. The site is outside the Aquifer Protection Area. 5. Any existing sub-standard hydrants will need to be replaced and/or retrofitted with a quick- disconnect Storz fitting. 6. If a fire sprinkler system is necessary, then a separate fire sprinkler permit will be required. 7. City Code requires a System Development Charge (if not previously paid in full) for any new development or redevelopment. This fee is based on the size of the new water meter necessary to provide domestic water service to the new building. A redevelopment credit for the site may offset portions of the required SDC fee. SANITARY SEWER I. An 8" public sewer line currently serves this property. 2. Any floor drains within the proposed shops and storage will be required to he connected into the sanitary sewer, with appropriate oil/water separator. 3. City Code requires a System Development Charge (if not previously paid) for any new development. This fee is based on the size of the domestic water meter necessary to serve this site. And again, as with the water fee, the re-development credit for the site may offset portions of the required SDC fee. Page 2 12108/2004 4. This site is within the Honey Creek Special Assessment district. Assessment fees may apply ifnot previously paid in-full. SURFACE WATER I. Surface water conveyance facilities currently are serving this vicinity. Additional infrastructure may be necessary if impervious surfaces are increased. Water quality facilities will be necessary if new pollutant generating surfaces are added. 2. Surface Water facilities are required to be designed according to the requirements as set forth in the King County 1990 Surface Water Design manual. 3. Surface water System Development Charges are required for this site. This fee is based on new impervious surface added to the site (ifno new impervious surface is developed then no fee will be assessed). STREET IMPROVEMENTS I. The site is surrounded by fully improved roadway with curb, gutter, sidewalk and street lighting. Existing site ingress and egress is adequate. 2. If additional trips were generated, a traffic mitigation fee of $75 per additional trip will be assessed. GENERAL COMMENTS 1. Submittal of conceptual utility plans showing all existing and proposed utilities; including water mains, sewer mains, manholes, valves, hydrants, drainage facilities, drainage mains and catch basins is required for permit review. All existing utility easements on the site must also be shown on the site plan. A complete conceptual drainage plan, downstream analysis, and calculations for sizing the detention and water-quality treatment facilities will be required with the formal application of this project. If you have questions please call Mike Dotson, Plan Reviewer, at 425-430-7304. 2. Permit application must include an itemized cost of construction estimate for the utility and roadway improvements. The fee for review and inspection of these improvements is 5% of the first $100, 000 of the estimated cost; 4% of the next $100,000; and 3% of any additional cost. One-half of the fees are due upon permit application. 3. The applicant is responsible for any necessary private utility easements.

The existing site, which is approximately 10.6-acres in size (according to the King County Assessor's Record), contains multiple buildings and is a vocational college use. The proposal is to construct a 11,400 square foot two-story structure in the northeast section of the campus. The proposed site is currently an undeveloped, grass slope with parking and an overhead power easement to the east and existing parking and storage area to the west. The proposed use of the first floor is for Facilities and Maintenance Department containing 5,400 square feet and the second floor for use as classroom for Early Childhood Education containing 6,000 square feet. The applicant's narrative further discussed building design and materials. Zoning: The subject site is designated Light Industrial (IL) on the City's Zoning Map and Public Use (P-suffix). The IL zone allows for a range of uses, including other higher education institutions, schools/studios, arts and crafts, trade or vocational schools. The P-suffix requires written notice to the owners of all property within a 300-foot radius of the site or facility, at least 60 days in advance of any of the following: 1) A proposed change of use of the premises; 2) A proposed change of the major tenant and/or tenant group using the premises if such change is determined to have probable major adverse impacts to the immediate surrounding area; or 3) Any proposed change of ownership of the premises. The proposal is for a new maintenance / classroom building for the existing use, Renton Technicat College. Development Standards: The proposal's compliance with the IL zone development standards is addressed below: Lot Coverage -The IL zone allows building coverage at a maximum of 65% of the lot area. Applicant will be required to submit with the formal land use application lot coverage calculation for the entire site. Height -The IL zone allows a maximum building height of 50 feet. The proposal. is for a two-story building however the overall height was not included with the pre-application for staff to further comment on compliance. Renton Technical Maintenan~tl Building December 7, 2004 r're-Application Meeting Page 2 of 3 SetbackslLandscaping - A minimum 20-foot landscaped building setback is required from all principal arterial street frontages and a minimum 15-foot landscaped building setback is required from all other street frontages. No rear or interior side yard setbacks are required unless the parcel abuts a residentially zoned property (i.e., R-1, R-5, R-8, RMH, R-10, R-14, RM). The proposed structure in internal to the overall site and therefore not abutting any streets. The IL zone requires that all portions of the site not covered by structures, required parking, access, circulation or service areas be maintained as permeable areas and improved with native, drought- resistant vegetative cover. ScreeninglOutdoor Storage -Screening must be provided for all surface-mounted and roof top utility and mechanical equipment. In addition, garbage dumpsters and recyclable areas must be screened pursuant to RMC section 4-4-090C7. Approval of the proposed locations of dumpster areas by Rainier Waste Management is recommended. Requirements for outdoor loading, repair, maintenance or work areas; outdoor storage, refuse or dumpster areas shall be in compliance pursuant to RMC section 4-4- 095 (copy included in packet). Parking -The parking regulations require that a specific number of off-street parking stalls based on the amount of square footage dedicated to certain uses be provided entirely within the boundaries of the property. The following ratio is applicable to the project: • Colleges and universities. arts and crafts schoolslstudios, and trade or vocational schools: One parking stall per employee plus one for every 3 students residing on campus, plus one space for every 5 day students not residing on campus. In addition, if buses for transportation of students are kept at the school, one off-street parking space shall be provided for each bus of a size sufficient to park each bus. Parking calculations were not inctuded in the pre-application information. The applicant wilt be required at the time of formal tand use application to provide parking calculation of the subject site and the overall campus use. It should be noted that the parking regulations specify standard stall dimensions of 9 feet x 20 feet, compact dimensions of 8% feet x 16 feet, and parallel stall dimensions of 9 feet x 23 feet. An aisle width of 24 feet is required for 90 degree parking stalls and a width of 18 feet is required for parallel stalls. ADA accessible stalls must be a minimum of 8 feet in width by 20 feet in length, with an adjacent access aisle of 8 feet in width for van accessible spaces. The appropriate amount of ADA accessible stalls based on the total number of spaces must be provided. Comprehensive Land Use: Site is located within the Center Institution Comprehensive Land Use Map designation. Objective LU-V: Assure that adequate land and infrastructure are available for the development and expansion of facilities to serve the post secondary educational and health care needs of the area and protect adjacent uses from impacts of these more intensive uses. The proposed structure is for use as classroom and facilities and maintenance area. Policy LU-142: Expansion of these existing campus facilities (i.e. Renton Technical College, Valley Medical Center) should be limited until the master plans have been approved by the City. The proposed permit structure is to replace two existing portable structures currently in use and located on another site on the campus. Critical Areas: The subject site is located within a Moderate Landslide Hazard area, and near andlor on a Protected Slope (40%) and will require environmental (SEPA) review. As a result, the applicant would be required to provide the City with a geotechnical analysis completed by a geotechnical engineer with the SEP A. The geotechnical report would need to depict the degree of slope, along with any proposed setbacks andlor construction mitigation measures. The geotechnical analysis may be recommended for a secondary review at the applicant's expense. The secondary analysis would need to be completed prior to the City issuing a threshold determination for the project. Permit Requirements: The proposal would require Administrative Site Plan and Environmental (SEPA) Review. Both permits would be reviewed concurrently in an estimated timeframe of 6 to 8 weeks. The application fee for joint land use applications is full price for the most expensive permit (Site Plan at $1,000) and half off any subsequent permits ($500 for the Environmental Review and $500 for the Binding Site Plan). In addition, $0.37 per mailing label would be required Renton Technical Maintenan"" Building December 7, 2004 r're-Application Meeting Page 3 of3 for notification to surrounding property owners. Detailed information regarding the land use application submittal is provided in the packet. In addition to the required land use permits, separate building/demolition, construction and sign permits would be required. The review of these permits may occur concurrently with the review of the land use permits, but cannot be issued prior to the completion of any required appeal periods. A handout listing all of the City's Development related fees is included in your packet for your review. cc: Jennifer Henning Renton Technical College Maintenance! Classroom Building Project Narrative PROJECT NARRATIVE General: DEVELOPMENT PLANNING CITY OF RENTON MAR 30 2005 RECEIVED The proposed project is the Renton Technical College (RTC) Maintenance and Classroom Building. It will be located on the RTC campus, which is at 3000 NE 4th Street, Renton, Washington, 98056. Land Use Permits: An Administrative Site Plan Review and an Environmental Review with completed Environmental Checklist (SEPA Checklist) are the land use permits required for the proposed project, according to the City of Renton's pre-application review comments. Site: This proposed new building site is located in the northeast section of the RTC campus; south of the Childcare Center (Bldg. M) and east of Construction Education Building (Bldg L). Currently the site is an undeveloped, grass slope that serves as localized grade transition zone. The area east of the proposed building site is dedicated to campus parking as well as easement for overhead, high voltage power lines; both of which parallel Monroe Avenue NE. To the west of the proposed site is an existing campus road used primarily by service vehicles. In the vicinity of the proposed development is an at-grade concrete stairway serving pedestrian traffic from the upper parking areas to campus buildings. This pedestrian link will be rebuilt as an integrated component to the proposed landscape development. Existing parking and storage area alongside the campus road will be maintained and reused. Currently the area is used by an automotive instructional program as storage of "project" vehicles. This area will be converted and fenced for use by the Facilities Department for vehicle parking and an outdoor storage area. In addition, short-term parking is planned adjacent to the proposed building at both levels. The upper student parking areas will remain unchanged. Site Features and Drainage: The project will provide stonn water runoff control per the 1990 King County Surface Water Drainage Manual (KCSWDM) and City of Renton Engineering Standards. Surface water runoff from new rooftop areas and walkways will be collected into an onsite infiltration system. Runoff treatment will not be provided for this project since the new impervious pollution-generating surface is less than one acre, per section 1.3.5 of the 1990 KCSWDM. This development will replace approximately 8,500 square feet of pollution-generating impervious surface. Existing Drainage and Site Conditions-The project site consists of approximately 0.40 acres of the north portion of the Renton Technical College campus. The site is currently comprised of landscaped areas, asphalt parking areas, and concrete sidewalks. The project site lies within the Lower Cedar River Sub-basin of the Cedar River Drainage Basin. The site slopes from east to west at approximately 25% with a 20-fool elevation change. This slope is defined as a "sensitive slope" under the King County sensitive area folio. S.M. Stemper Architects Page 1 of:3 , I Renton Technical College Maintenance! Classroom Building Project Narrative Storm water discharges through a private storm system along the western edge of the campus. Runoff is then routed to the public storm system in Kirkland Avenue Northeast. Proposed Drainage System-The proposed project will add a new two-story, 11,088 square-foot building with associated parking and landscaping area. Surface runoff generated from the rooftop of the proposed building, walkways, and landscaped areas will be collected and routed to the underground infiltration chambers. Storm water runoff will infiltrate for storms up to and including the lOO-year design storm event. Soils Existing soil conditions include approximately I foot of fill over advance outwash. Advance outwash soils consists of a medium dense to dense, stratified mixture of fine to course sand with a trace of silt (per the Geotechnical Engineering report). Estimated quantities of excavation include 4,090 cubic yards. Estimated quantities of fill include 2,310 cubic yards. Building: Renton Technical College maintains three portable structures located at the south end of campus, east of Building A. The portables provide classroom and administrative space for the Early Childhood Education program. The existing portables are old, are in disrepair, are costly to operate, and the cost to renovate these structures greatly exceeds their assessed value. The building Facilities and Maintenance department is currently scattered throughout campus with primary components located in Building A and in Building K. The college has received state funding to demolish the existing portables and consolidate the existing maintenance staff and activities into a new building. The proposed new building is a 11,088 s.f two story structure, with at-grade access to each floor. This is accomplished by capitalizing on a site that straddles a sloping transition between two developed campus circulation paths. The planning criteria for the proposed project have been tailored to take full advantage of this unique access arrangement. Building Use: The programmatic function of the building is divided into two distinct areas: Facilities and Maintenance Department and Early Childhood Education. There is no direct connection desired between these functions and therefore no common corridors, stairs, restrooms, or storage. The Facilities area (5280 sf total) will contain maintenance shops, parts storage, tool storage, custodial storage, facilities storage, staff break room, and lockers. In addition there will be facilities maintenance administrative office space, conference room, document record storage, and a campus security office. There will be a variety of access points, including multiple roll up doors for the equipment and storage zones as well as pedestrian doors to the administrative sections. The Classroom area (5808 sf total) is to be identified by Early Childhood Education students and staff as unique from the maintenance department and therefore have its own entrance. A common hallway S.M. Stemper Architects Page 2 01'3 , , Renton Technical College Maintenancel Classroom Building Project Narrative will serve each of the (4) (900sf) classrooms. Within each classroom will be an adjoining instructor's office, a teaching wall, and ample daylight. Zoning: The current zoning of the campus is II.. (Industrial Light). A trade or vocational school is permitted in this zoning. The areas surrounding the RTC campus are primarily zoned Residential (R-8, R-IO, and RM-F), and Commercial (CA). Pro ject Costs: The proposed project is estimated to cost $ 2,300,000.00 for construction.

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. Govemmental 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.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. Renton Technical College maintains three portable structures located at the south end of campus, east of Building A. The portables provide classroom and administrative space for the Early Childhood Education program. The existing portables are an eyesore to the campus. They are old, are in disrepair, are costly to operate, and the cost to renovate these structures greatly exceeds their assessed value. The building Facilities and Maintenance department is currently scattered throughout campus with primary components located in Building A and in Building K. The proposed new building is an 11,088 s.f two story structure, with at-grade access to each floor. This is accomplished by capitalizing on a site that straddles a sloping transition between two developed campus circulation paths. The planning criteria for the proposed project have been tailored to take full advantage of this unique access arrangement. Site: This proposed new building site is located in the northeast section of the RTC campus; south of the Childcare Center (Bldg. M) and east of Construction Education Building (Bldg L). Currently the s~e is an undeveloped, grass slope that serves as localized grade transition zone. The area east of the proposed building site is dedicated to campus parking as well as easement for overhead, high voltage power lines; both of which parallel Monroe Avenue NE. To the west of the proposed site is an existing campus road used primarily by service vehicles. In the vicinity of the proposed development is an at-grade concrete stairway serving pedestrian traffic from the upper parking areas to campus buildings. This pedestrian link will be rebuilt as an integrated component to the proposed landscape development. Existing parking and storage area alongside the campus road will be maintained and reused. Currently the area is used by an automotive instructional program as storage of "project" vehicles. This area will be converted and fenced for use by the Facilities Department for vehicle parking and an ou1door storage area. The upper student parking areas will remain unchanged. Building Use: The programmatic function of the building is divided into two distinct areas: Facilities and Maintenance Department and Early Childhood Education. There is no direct connection desired between these functions and therefore no common corridors, stairs, restrooms, or storage. The Facilities area (5280 sf total) will contain maintenance shops, parts storage, tool storage, custodial storage, facilities storage, staff break room, and lockers. In addition there will be facilities maintenance administrative office space, conference room, document record storage, and a campus security office. There will be a variety of access points, including multiple rollup doors for the equipment and storage zones as well as pedestrian doors to the administrative sections. The Classroom area (5808sf total) is to be identified by Early Childhood Education students and staff as unique from the maintenance department and therefore have its own entrance. A common hallway will serve each of the (4) (900sf) classrooms. Within each classroom will be an adjoining instructor's office, a teaching wall, and ample daylight. \\Stempernt\activejobs\ RTC\20Q4\0404_03 Maintenance build'lng\0404_03 Permitflng\Conditional Use Permit\CUP Submittal Oocuments\SEPA checklist-proposal question 11.doc03/18105 Renton Technical College Maintenance! Classroom Building Construction Mitigation CONSTRUCTION MITIGA TION Construction dates and times: DEVELOPMENT PLANNINC CITY OF RENTON MAR 302005 RECEIVED Construction is scheduled to begin July 2005, and will continue until February 2006-7 months. During construction, operations on the site will typically last from 7:00 am to 5:00 pm. Proposed access to the site will be from Monroe Avenue NE, and NE 7'" Street. The contractor will be instructed to use the northern-most campus entrance from Monroe Avenue NE. This entrance will cause minimal impact to transportation in the area as it is the furthest entrance from the light and intersection at Monroe Avenue NE and NE 4" Street. The contractor will also use the campus entrance on NE 7· Street, which is the most direct access point for the lower portion of the site. Additionally, to minimize transportation impacts, the contractor will be instructed to employ flaggers when large trucks, such as those transporting large beams, approach the site. The following Temporary Erosion and Soil Control measures will be made during construction: o To ensure that the disturbance of the site is limited to the development area, the clearing limits will be clearly staked prior to any clearing or grading as shown on the TESC plan. o Catch basin protection will be used on existing and future catch basins to reduce sediment- laden water from entering the existing stonn system during construction. o Cover measures such as mulch, seeding, or plastic sheeting will be implemented for disturbed areas greater than 5,000 square feet in accordance with the City of Renton Standards. o Temporary sediment storage tanks are included to allow sediment to settle out of onsite runoff prior to discharging from the site. o All construction debris will be promptly removed from the site to minimize demolition and construction impacts On the site. The contractor shall implement additional BMP's as required andlor recommended by the City of Renton inspector or other agencies as required to prevent demolition and construction debris, waste material, fuel, oil, lubricants, and other fluids from entering the public stonn system. Additional Control Measures: The contractor will be instructed to minimize the construction dust. During minimal dust generating activities, the contractor will be instructed to water the dirt to minimize dust. If the weather creates conditions for excessive dust generation, the contractor will be instructed to limit excavation activities to more favorable conditions. S.M. Stemper Architects Page I of I Habitat Data Report LANDSCAPE ARCHITECTS 1148 NW Leary Way, Seattle, Washington 98107 Telephone (206) 789-2133 Fax (206) 789-2186 DEVELOPME CITY OF ~f:r~~tJING MAR 302005 RECEIVED The existing vegetated area of the site includes approximately 13,000 square feet. The building is being developed on a 25 percent slope with a 20-foot elevation change. The back wall of the building will serve as a retaining wall. The vegetation on the existing site is generally well established which helps in the stabilization of the slope. The vegetation is primarily maintained grass with some mature shrubs and smaller evergreen and deciduous trees. There are 7 trees to be removed during construction, 2 Douglas fir and 5 Prunus (ornamental cherry) (See Clearing / Tree Inventory Plan). The habitat value of the existing landscape is minimal as the site is within the campus of the college, is maintained on a regular schedule and surrounded by parking lots and internal campus drives. The project will maintain as much exiting plant material as possible on the site, much of which is on the south end of the proposed building. This will reduce the cost of reestablishing the landscape in those areas, will reduce the need for erosion control measures and reduce the disturbance to any habitat values. Specifications for tree and plant protection will be maintained through the construction period. Landscape Development Report The south end of the building will receive more detailed landscape development then other areas of the site. This location is nearer to the acti ve area of the campus and will receive more pedestrian activity. The east side/entry to the classrooms may receive some landscape treatment however space will dictate the amount and extent of this landscape development. The north end of the building will likely only entail the reestablishment of the ground cover that will be disturbed during construction. It is likely that no planting will occur on the west side of the building due to the necessary vehicle access. Plant Material Generally, the plant material associated with the campus reflects native and non-native species. Our criteria for plant selection will include drought tolerant, primarily native and low maintenance. In several areas of campus, plant materials have been use in a location that requires annual and semi-annual pruning to avoid covering windows and walkways. Proper selection of plant materials will avoid this problem. . , Irrigation An automatic, underground irrigation system will be designed to be economical to install and maintain. It will deliver the amount of water necessary to maintain the plant material in a thriving condition. The equipment specified will reflect the irrigation equipment used in other areas of the campus for ease of operation and maintenance. A moisture sensor will be used to reflect the natural precipitation to avoid over watering during times of rainfall.

PROJECT OVERVIEW General Description The following Technicallnformation Report (TIR) provides the technical information and design background required for developing the Drainage and Temporary Erosion and Sedimentation Control (TESC) Plan for the project. The design for the new Maintenance/Classroom Building at Renton Technical College will be based on the requirements set forth in the 1990 King County. Surface Water Design Manual (KCSWDM). The proposed Maintenance/Classroom Building is located within the Renton Technical College campus, located at 3000 Northeast 4th Street in Renton, Washington (see Figure 2 -Site Vicinif:1J Map). The project site is in the north portion of the campus, west of Kirkland Avenue Northeast, and south of Northeast 7th Street. It is within the Lower Cedar River Community Basin and Drainage Sub- basin. The site currently consists of a sloped landscaped area between two parking areas: one to the east and the other to the west. A concrete staircase connects the two parking areas along the south side of the project area. The development involves clearing and excavating the site for construction of a two-story, 11,088 square-foot building. Additional improvements include repairing the upper and lower parking lots surrounding the building, concrete sidewalks, landscaping, and associated utilities. The project will provide stormwater runoff control per the 1990 King County. Surface Water Drainage Manual (KCSWDM) and City of Renton Engineering Standards. Surface water runoff from new rooftop areas and walkways will be collected into an onsite infiltration system. Runoff treatment will not be provided for this project since the new impervious pollution-generating surface is less than one acre, per section 1.3.5 of the 1990 KCSWDM .. This development will replace approximately 8,500 square feet of pollution-generating impervious surface. Existing Drainage and Site Conditions The project site consists of approximately 0.40 acres of the north portion of the Renton Technical College campus .. 11,e site is currently comprised of landscaped areas, asphalt parking areas, and concrete sidewalks (see Figure 5 -. Existing Site Conditions) .. The project site lies within the Lower Cedar River Sub-basin of the Cedar. River Drainage Basin. The site slopes from east to west at approximately 25% with a 20-foot elevation change. This slope is defined as a "sensitive slope" under the King County. sensitive area folio ..

SITE HYDROLOGY ANALYSIS AND DESIGN Storm Runoff Control Analysis The drainage system for the project site was designed in accordance with the 1990 King County Surface Water Design Manual (KCSWDM). The peak runoff rates for the hydraulic design were determined using the Santa Barbara Urban Hydrograph (SBUH) Method with 24-hour Type I-A rainfall distribution. The hydrologic computer program Waterworks Version 4.09 was used to develop and manipulate design hydrographs (see attached storm water calculations). Storm runoff control and will be achieved through underground infiItration chambers, Stonntech Systems. Impervious areas, including rooftop, paving, and sidewalk and pervious areas for the proposed site conditions are shown in the following table: Tab e 1: Propose dD . ralnage B . aSln Areas Land Cover Area (acres) Impervious Area (ac) 0.34 Pervious Area (ac) 0.06 Total Area (ac) 0.40 The infiltration chambers are designed to infiltrate the 100-year design storm event under developed conditions. The infiltration rate used to design the infiltration chambers was determined by a study conducted by Associated Earth Sciences, Inc. The design infiItration rate is 2 inches/hour. The required storage volume is 2,693 cubic feet, with a correction factor of 30%. The proposed infiltration system is designed to provide 2,693 cubic feet of storage volume with 31 chambers, including washed gravel surrounding the chambers. Water Quality Analysis Less than one acre of new pollution-generating impervious surface is proposed as part of this development. Therefore, no water quality treatment will be provided for this development. COUGHLIN PORTER LUNDEEN 6 March 10, 2005 P; \ Rentol!

TEMPORARY EROSION AND SEDIMENT CONTROL To minimize the aOlount of sedinlent laden water from leaving the site during the construction process, a temporary. erosion and sedimentation control (fEsq plan has been designed for this project in accordance with KCSWDM. The TESC plan indicates the minimum necessary measures that the contractor shall implement during the construction process. Best Management Practices (BMP's) are defined as physical, structural and/ or managerial practices that, when used in combination, prevent or reduce pollution of water caused by construction activities. The TESC plan for the proposed project has been designed to protect off-site properties as well as minimize the quantity of sediment-laden water from entering the public storm system. The following BMP's will be included on the TESC plan for this project: o To ensure that the disturbance of the site is limited to the development area, the clearing limits will be clearly staked prior to any clearing or grading as shown on the TESC plan. o Catch basin protection will be used on existing and future catch basins to reduce sediment-laden water from entering the existing storm system during construction. o Cover measures such as mulch, seeding, Or plastic sheeting will be implemented for disturbed areas greater than 5,000 square feet in accordance with the City of Renton Standards. o Temporary sediment storage tanks are included to allow sediment to setUe out of onsite runoff prior to discharging from fue site. o All construction debris will be prompUy removed from the site to minimize demolition and construction impacts on fue site .. The contractor shall implement additional BMP's as required and! or recommended by fue City of Renton inspector or other agencies as required to prevent demolition and construction debris, waste material, fuel, oil, lubricants, and other fluids from entering fue public storm system.

PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and preliminary geotechnical engineering study for the proposed Maintenance/Classroom Building (Building N) within the Renton Technical College campus located at 3000 NE 4th Street, Renton, Washington. The general location of the site is depicted on the Vicinity Map, Figure 1. The proposed building location and approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 2. Our recommendations are preliminary in that site grading, structural plans, and construction methods have not been finalized at the time of this report. In the event that any changes in the nature, design, or location of the structure are planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1.1 Purpose and Scope The purpose of this study was to provide subsurface data to be utilized in the preliminary design and development of the subject project. Our study included a review of available geologic literature, excavating an exploration pit, drilling an exploration boring, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments and shallow ground water conditions. Infiltration testing was conducted within the exploration pit. Geologic hazard evaluations and geotechnical engineering studies were also conducted to determine suitable geologic hazard mitigation techniques, the type of suitable foundation, allowable foundation soil bearing pressures, anticipated settlements, temporary slope/shoring recommendations, basement/retaining wall lateral pressures, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and offers hazard mitigation, development, and infiltration recommendations based on our present understanding of the project. 1.2 Authorization Authorization to proceed with this study was granted by Ms. Sally MacGregor of S.M. Stemper Architects, PLLC. Our study was accomplished in general accordance with our proposal letter dated November 24, 2004. This report has been prepared for the exclusive use of the Renton Technical College, S.M. Stemper Architects, PLLC, and their agents for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. It must be understood that no recommendations February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Present plans call for a two-story structure with daylight basement with slab-on-grade floors planned for the basement area of the building. The lowest level will be set at the same elevation as westerly adjacent Building L. The second floor of the proposed new building will be at approximately the same elevation as the easterly adjacent parking area. New access stairs and a courtyard retaining wall are planned along the south end of the proposed building. The property is situated at 3000 NE 4'" Street in Renton, Washington and is the site of Renton Technical College. The proposed new building will be situated within the northeastern portion of the school campus. An asphalt concrete access drive/parking area extends along the western edge of the proposed building area. A moderate, 15-to 20-foot high, grass-covered slope descends across the proposed building area from the east parking lot to the west access drive/parking area. A rockery wall extends north-south along the toe of the slope. The existing site slope is considered by the City of Renton code to be a "Medium Landslide Hazard," which is defined in the Renton Municipal Code, Chapter 3, Section 4-3-050, paragraph 4.c.ii as "Areas with slopes between fifteen percent (15%) and forty percent (40%) and underlain by soils that consist largely of sand, gravel or glacial till." Based on topographic information provided to us, the overall slope gradient measured from top to toe of slope is approximately 20 to 25 percent (5H:IV [Horizontal:Vertical] to 4H:IV). As proposed, site development will require temporary cuts to a height of approximately 20 feet along the easterly adjacent parking area. Where space limitations result in temporary excavations steeper or higher than recommended herein, shoring will be required. The actual location and configuration of the temporary cut will factor into the determination regarding how much and where shoring will be required. 3.0 SUBSURFACE EXPLORATION Our field study included drilling one exploration boring, excavating one exploration pit, performing infiltration testing, and conducting geologic and geologic hazard reconnaissance to gain information about the site. The various types of sediments, as well as the depths where characteristics of the sediments changed, are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed may represent gradational variations between sediment types in the field. If changes occurred between February 8, 2005 ASSOCIATED EARm SCIENCES, INC.

Our explorations were approximately located in the field by estimation from known site features shown on the referenced site plan by Coughlin Porter Lundeen. The conclusions and recommendations presented in this report are based on subsurface conditions revealed in the exploration boring and exploration pit completed for this study. The number, location, and depth of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. It should be noted that differing subsurface conditions may sometimes be present due to the random nature of deposition and the alteration of topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. 3.1 Exploration Boring The exploration boring was completed by advancing a 33/8-inch, inside-diameter, hollow-stem auger with a track-mounted drill rig. During the drilling process, samples were obtained at generally 2.5-or 5.0-foot depth intervals. The boring was continuously observed and logged by a geotechnical engineer from our firm. The exploration log presented in the Appendix is based on the field log, drilling action, and inspection of the samples secured. Disturbed but representative samples were obtained by using the Standard Penetration Test (SPT) procedure in accordance with American Society for Testing and Materials (ASTM):D 1586. This test and sampling method consists of driving a standard, 2-inch, outside-diameter, split-barrel sampler a distance of 18 inches into the soil with a 140-pound harruner free-falling a distance of 30 inches. The number of blows for each 6-inch interval is recorded and the number of blows required to drive the sampler the final 12 inches is known as the Standard Penetration Resistance ("N") or blow count. If a total of 50 is recorded within one 6-inch interval, the blow count is recorded as the number of blows for the corresponding number of inches of penetration. The resistance, or N-value, provides a measure of the relative density of granular soils or the relative consistency of cohesive soils; these values are plotted on the attached boring log. The samples obtained from the split-barrel sampler were classified in the field and representative portions placed in watertight containers. The samples were then transported to our laboratory for further visual classification and laboratory tes ting, as necessary. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

The exploration pit permitted direct, visual observation of subsurface conditions. Materials encountered in the exploration pit were studied and classified in the field by a geotechnical engineer from our firm. A Pilot Infiltration Test (PIT) was conducted at a depth of approximately 3.5 feet in the exploration pit. Upon completion of the test, the pit was excavated to a depth of 12 feet. The exploration pit was backfilled immediately after examination and logging. Selected samples recovered from the exploration were transported to our laboratory for further visual classificatio!1 and testing, as necessary. 3.3 Infiltration Testing An infiltration test was conducted at a depth of approximately 3.5 feet below existing ground surface in EP-l in the vicinity of the proposed storm water management structure adjacent to the southwest corner of the proposed maintenance/classroom building. The infiltration testing was conducted using a method generally corresponding to the procedure described for the Pilot Infiltration Test (PIT) in the Washington State Department of Ecology 2001 Stormwater Management Manual for Western Washington (Ecology manual). This test is conducted by discharging water into a flat-bottomed pit of known dimensions for a 4-hour "soaking period" to allow the receptor soils in the immediate vicinity of the pit to become saturated. After completion of the soaking period, water is discharged into the pit at a rate sufficient to maintain a head in the pit. This is continued until the discharge rate required to maintain a constant head remains fairly consistent over a period of 1 hour. Ground water infiltration was conducted inside a large-diameter (72-inch-diameter) iron ring embedded into the unweathered advance outwash soil. The large-diameter ring was used in lieu of the open pit described in the Ecology Manual to avoid or reduce testing errors due to such factors as sidewall collapse, inaccurate measurement of open pit areas, and sidewall infiltration. The water source used for the test consisted of a fire hydrant located adjacent to the southwest portion of the proposed building area. Water was discharged into the pit through a fabric diffuser to minimize turbulence and scouring of the pit bottom. A flow meter/totalizer was used to monitor the water discharge rate and total flow. A staff gauge with O.OI-foot divisions was installed in the pit to monitor the depth of water during testing. For the constant head test, a head of approximately 0.80 feet was maintained in the pit. Following completion of the constant-head test, the flow of water into the pit was discontinued and the rate of water level decline (falling head) in the pit was monitored. All infiltration test data was recorded by hand in the field and subsequently transferred to an electronic spreadsheet to allow more accurate and consistent infiltration rate calculations. The infiltration testing results are summarized below in Table 1. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Exploration boring EB-l was drilled within the higher elevation, eastern portion of the site; exploration pit EP-l was excavated at the toe of the slope, southwesterly adjacent to the proposed structure. As shown on the field logs, exploration boring EB-l encountered approximately 2 feet of relatively loose sandy fill overlying medium dense to dense sand and February 8, 2005 ASSOCIATED EARTH SCIENCES, INC .

Exploration pit EP-l encountered approximately 1 foot of loose to medium dense sand fill over medium dense to dense, stratified, fine to coarse sand with a trace of silt to the bottom of the pit at 12 feet. The following sections present more detailed subsurface information. 4.1 Stratigraphy Fill Fill soils (those not naturally placed) were encountered to a depth of approximately 2 feet in exploration boring EB-l and to a depth of approximately 1 foot in EP-l. Based on the classification of the native soils encountered on-site, it is considered likely that the fill soil was derived from on-site sources and placed during one of the phases of earlier site development. The fill generally consisted of a loose mixture of silt and sand. The fill soils as observed are considered unsuitable for support of the proposed structure. Existing fill soil may be considered for use as structural fill where moisture-conditioned and compacted as recommended in the Structural Fill Section of this report. Fill depth may vary across the proposed building area. Advance Outwash Below the fill, a medium dense to dense, stratified mixture of fine to coarse sand with a trace of silt interpreted as advance outwash was encountered. Advance outwash sediments were deposited as outwash from rivers flowing from the base of the southward advancing glacial front. The advance outwash has been overridden by several thousand feet of ice resulting in a compact, competent soil mass. This process resulted in a compact soil possessing high strength and relatively low compressibility characteristics. The medium dense to dense advance outwash is considered to be suitable for foundation support. The advance outwash soil may be used as structural fill where moisture-conditioned and compacted as detailed in the Structural Fill Section of this report. 4.2 Hydrology No ground water/seepage was encountered in our explorations. It should be noted that fluctuations in the level of the ground water may occur due to the time of the year, variations in rainfall, irrigation, on-and off-site land usage, and other factors. 4.3 Site Infiltration The Ecology Manual defines three methods for determining long-term infiltration rate. The methods are identified in the following paragraphs and results, as related to the project site, are presented. February 8, 2005 ASSOCIATED EARTH SCIENCES. INC.

Washington Method 1 Subswjace Exploration. Geologic Hazards. and Preliminary Geotechnical Engineering Report Proiec/ and Site Conditions The results of grain size analyses conducted on soil samples obtained from EP-l excavated in the vicinity of the proposed storm water facility indicate a silt content ranging between 0.6 and 4.7 percent. Using the United States Department of Agriculture (USDA) Textural Triangle presented as Figure 7.1 in the Ecology Manual, the texture of the samples tested is determined to be sand. Using this texture classification in conjunction with Table 7.1 in the Ecology Manual, an estimated long-term (design) infiltration rate of 2 inches per hour is an allowable estimation for site soils. Method 2 Method 2 presented in the Ecology Manual allows estimation of long-term (design) infiltration rate directly from soil gradation data. This method requires a determination of the effective size of the grains comprising the soil. The effective size (DID) is defined as the size corresponding to 10 percent on the grain size curve. The effective size of soil within samples obtained from the site ranges from 0.1 (EP-l at 3 to 5.5 feet) to 0.33 (EP-1 at 5.5 to 11 feet). Using the effective size determined for samples tested and Table 7.2 presented in the Ecology Manual, the corresponding estimated long-term (design) infiltration rate for site soil ranges from 2 to 6.5 inches per hour. Method 3 As described in Section 3.3 Infiltration Testing, a PIT was conducted in general conformance with Method 3 presented in the Ecology Manual. Test results are presented in Table 2. Infiltration Design (Long-Term) Rate As indicated on the log of EP-l, the upper 5.5 feet of soil in the vicinity of the infiltration test consisted of sand with a trace of silt. Soil below 5.5 feet consisted of stratified fine to coarse sand. The PIT was conducted at a depth of 3.5 feet in the sand with a trace of silt. Based on the results of grain size testing, it is considered likely that a higher infiltration rate would have been observed had the PIT been conducted within the sand soil encountered at a lower elevation. Based on this and the long-term infiltration rate determined by Methods 1 and 2, it is our opinion that the infiltration rate determined during the PIT is roughly representative of infiltration rates to be expected over the design life of the proposed infiltration structure, thus, we recommend the following long-term infiltration rate.

GEOLOGIC HAZARDS AND MITIGATIONS The following discussion of potential geologic hazards is based on the geologic, slope, and ground water conditions as observed and discussed herein. The discussion will be limited to seismic, landslide or mass-wasting, and erosion, including sediment transporL 5.0 SEISMIC HAZARDS AND RECOMMENDED MITIGATION Earthquakes occur in the Puget Lowland with great regularity. The vast majority of these events are small and are usually not felt by people. However, large earthquakes do occur as evidenced by the 1949, 7-2-magnitude event; the 1965, 6.5-magnitude event; and the 20016.9- magnitude evenL The 1949 earthquake appears to have been the largest in this area during recorded history. Evaluation of earthquake return rates indicates that an earthquake of the magnitude between 5.5 and 6.0 is likely within a given approximate 20-year period. Generally, there are four types of potential geologic hazards associated with large seismic events: 1) surficial ground rupture; 2) liquefaction; 3) ground motion; and 4) seismically induced landslides. The potential for each of these hazards to adversely impact the proposed project is discussed below. 5.1 Surficial Ground Rupture Generally, the largest earthquakes which have occurred in the Puget Sound area are sub-crustal events with epicenters ranging from 50 to 70 kilometers in depth. For this reason, no surficial faulting or earth rupture as a result of seismic activity has been documented to date within at least 5 miles of the site. Therefore, it is our opinion, based on existing geologic data, that the risk of surface rupture impacting the proposed project is low and no mitigations are necessary. 5.2 Liquefaction Liquefaction is a process through which unconsolidated soil loses strength as a result of vibratory shaking, such as that which occurs during a seismic event. During normal conditions, the weight of the soil is supported by both grain-to-grain contacts and by the . pressure within the pore spaces of the soil below the water table. Extreme vibratory shaking can disrupt the grain-to-grain contact, increase the pore pressure, and result in a decrease in soil shear strength. The soil is said to be liquefied when nearly all of the weight of the soil is supported by pore pressure alone. Liquefaction can result in deformation of the sediment and settlement of overlying structures. Areas most susceptible to liquefaction include those areas underlain by coarse silt and sand with low relative densities, accompanied by a shallow water table.

Based on soil density and the absence of ground water, site soils are considered to have a low potential for liquefaction. 5.3 Ground Motion The project site is located within a Zone 3 rating for seismic activity on a scale of 1 (lowest) to 4 (highest) based on the Seismic Zone Map of the United States, Figure No. 16-2 in the 1997 edition of the Uniform Building Code (UBC). This zonation is based on past earthquake activity in the Puget Sound region. As such, design recommendations in the report accommodate the possible effect of seismic activity in areas with a Zone 3 rating corresponding to a peak ground acceleration of 0.3g (a Richter magnitude 7.5 earthquake occurring directly beneath the site) in accordance with UBC guidelines. Based on site stratigraphy and visual reconnaissance of the site, it is our opinion that any earthquake damage to the proposed structure founded on suitable bearing strata would be caused by the intensity and acceleration associated with the event and not any of the impacts discussed in the Seismic Hazards and Recommended Mitigation section of this report. Structural design of the building should take into consideration stress caused by seismically induced earth shaking. Due to the thickness and consistency of the sediments underlying the site, amplification of seismic motion upward through this soil column is possible. The approximate proposed building period should be compared to the estimated soil column period of vibration to check for resonant conditions. It is these conditions that result in our recommendation for the more stringent SD soil type classification for use with the UBC standards and Site Class D for use with the International Building Code (!BC) as discussed below. Guidelines presented in the 2003 !BC, Section 1615, may be used. Information presented in Figure 1615(1) indicates a mapped spectral acceleration for short periods of S, = 1.37. Information presented in Figure 1615(2) indicates a mapped spectral acceleration for a 1 second period of Sl = 0.47. Based on the results of subsurface exploration and on an estimation of soil properties at depth utilizing available geologic data, Site Class "D" in conformance with Table 1615.1.1 may be used. Site coefficients F, = 1.0 and F, = 1.5 in conformance with!BC Tables 1615.1.2(1) and 1615(2), respectively, may be used. 5.4 Seismically Induced Landslides The existing slope within the building area is to be removed and replaced with a retaining wall as a part of site development.

No mitigations are recommended regarding seismically induced landslides. Slope stability is discussed further in the following section. 6.0 LANDSLIDE HAZARDS AND MITIGATION Generally, there are two types of landslides that commonly occur in the Puget Sound region. The first type is termed Earth Slump or Slump-Earth Flow. This type of earth movement is deep-seated and usually involves the regolith (topsoil) and the underlying sedimentary units. Slides of this type can be very large. The second type is termed Debris Slump or Debris Flow and usually involves the upper few feet of the regolith. This type of slide is very dependent on local drainage patterns and the resulting moisture content of the soils. Based on the site stratigraphy and visual geologic reconnaissance, the slope areas appear to be more susceptible to a shallow debris flow due to the presence of the glacially consolidated, advance outwash soil encountered below the surficially disturbed fill/topsoil horizon. A slope stability analysis was beyond the scope of this study, and therefore, the stability risks cannot be quantified by this study. However, it is our opinion that the seismic and static factors of safety would lie within generally accepted limits and that the deep-seated landslide risks on the site are low under both static and seismic conditions. The proposed development should not increase the risk of deep-seated movements provided the recommendations presented in this report are followed. As discussed earlier in this report, proposed development will eliminate the eXlstmg slope within the building area and will eliminate the potential risk of landslides affecting the proposed structure. Slopes will remain north and south of the proposed structure and adjacent to pedestrian walkways. Based on observed evidence of weathering and disturbance due to burrowing rodents, it is our opinion that shallow movement on the·slope areas to remain north and south of the proposed structure presents a low risk under current site conditions. Since local drainage, slope steepness, slope height, and vegetation cover largely influence the shallow stability and soil erosion, the planned development will require specific mitigation measures to avoid increasing the shallow earth movement risk. These mitigations include controlling runoff, establishing vegetation cover, and following the recommendations as outlined in this report. In our opinion, by following these recommendations, the risk of shallow earth movement on the site or on surrounding properties will not be increased by the proposed construction.

Erosion hazard areas are classified as having moderate to severe, severe, or very severe erosion potential by the Soil Conservation Service, United States Department of Agriculture (USDA). " Soils in the vicinity of the project are mapped by the USDA as Alderwood gravelly sandy loam on slopes of 6 to 15 percent. Site-specific information from explorations is in general agreement with USDA mapping. Some areas of Alderwood soils on slopes of 15 to 30 percent may be encountered, but are not mappable at the USDA map scale. Surface runoff and erosion hazards soil characteristics of these soil types are presented in Table 4. Table 4 Surface Runoff and Erosion Hazard Soil Characteristics Soil Type Percent Slope Surface Runoff Erosion Hazard Alderwood 6 to 15 Medium Moderate Alderwood 15 to 30 Medium to Rapid Moderate to Severe The on-site soils contain a significant amount of fines and are considered moisture-sensitive. Therefore, all permanent and temporary slopes should be protected from erosion. The following general erosion mitigation measures are recommended for use throughout the site . 1. All storm water from impermeable surfaces should be tightlined into approved storm water drainage systems. 2. To reduce the amount of sediment transport from the proposed construction area, silt fencing should be placed along the lower elevations of the cleared areas. 3. Temporary sediment catchment facilities, interceptor drainage swales, and surface conveyance swales should be installed to intercept runoff and eroded sediment prior to site work. Check dams should be installed as necessary. 4. Earthwork should proceed during the drier summer periods of the year and disturbed areas should be revegetated as soon as possible. Temporary erosion control measures should be maintained until permanent erosion control measures are established. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

All devices used to collect surface runoff should be directed into a tightline or swale system designed to convey the collected drainage to discharge within an approved storm drain system. 6. Soils that are to be reused around the site should be stored in such a manner as to reduce erosion. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, the use of low stockpiles in flat areas, or the use of straw bales/silt fences. 7. Prior to the onset of winter, any exposed subgrade should be hydroseeded, covered with plastic sheeting, or otherwise protected. Seed should be planted soon enough to have the grass established by October 31. If suitable ground cover vegetation is not established prior to the wet season, mulch cover or plastic sheeting should be used. 8. At the end of each workday, disturbed areas should be sloped to drain into a storm conveyance and seal-rolled to promote surface drainage. 9. A temporary , rock-surfaced construction entrance and staging areas should be established early in the project sequence. 10. All storm water from impermeable surfaces, including driveways and roofs, should be tightlined into approved facilities and not be directed onto or above steeply sloping areas. 11. As much of the natural vegetation on the slopes as is possible should be left intact during construction. Sloping areas without sufficient vegetation and areas stripped of vegetation during construction should be planted as soon as possible or otherwise protected. 12. Erosion control measures should be inspected regularly and maintained/improved as necessary to maintain function. 13. The surface of the slopes to remain adjacent to the proposed building and associated hardscape should be scarified, moisture-conditioned as necessary, and compacted. The resulting slope gradient should be as uniform as possible and should match that of the surrounding areas. 14. Regular pest control services should be employed to maintain the site free of burrowing rodents. February 8, 2005 ASSOCIATED EARTH SCIENCES. INC.

DESIGN RECOMMENDATIONS 8.0 INTRODUCTION Our exploration indicates that, from a geotechnical standpoint, the project area is suitable for the proposed development provided that the recommendations contained herein are properly followed. It is our understanding that column loads will be on the order of 100 to 150 kips. Subsurface conditions disclosed by our explorations revealed medium dense to dense advance outwash sediments at a depth of approximately 1 to 2 feet below existing ground surface. Given the loose nature of the fill and disturbed advance outwash soil, it is not recommended for support of building foundations. The existing fill and disturbed advance outwash materials may be suitable for reuse as structural fill provided the moisture content is maintained within the compactable range. Site development will require temporary cuts to a height of 20 feet (maximum) along the eastern, northern, and southern perimeters of the proposed structure. Where space limitations result in temporary excavations steeper or higher than recommended herein, shoring will be required. The actual location and configuration of the temporary cut will be factors in how much and where shoring will be required. Recommendations are presented in the Shoring - Soldier Pile Walls section of this report. 9.0 SITE PREPARATION Site preparation within the planned building area should include removal of all trees, landscape structures, pavements, brush, debris, and any other deleterious material. Additionally, any organic topsoil should be removed and the remaining roots grubbed. Any buried structures and/or utilities should be removed or relocated if they are encountered under/within the area to be developed. The resulting depressions that extend below or outside the planned excavation envelope should be backfilled with structural fill as discussed under the Structural Fill section of this report. 9.1 Temporary Cut Slopes In our opinion, stable construction slopes should be the responsibility of the contractor and should be determined during construction based on the conditions encountered at a particular location and time. For estimating purposes, however, we anticipate that temporary, unsupported cut slopes in the sandy fill and advance deposit soil can be planned at a maximum slope of 1.5H:IV. To provide additional protection, the top of a cut slope should begin no February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

As is typical with earthwork operations, some sloughing and raveling may occur and cut slope gradient may have to be adjusted in the field. In addition, WISHA/OSHA regulations should be followed at all times. Where space limitations result in temporary cuts steeper or higher than recommended herein, shoring will be required. The actual location and configuration of the temporary cut will factor into determination of how much and where shoring will be required. Recommendations are presented in the Shoring -Soldier Pile Walls section of this report. 9.2 Erosion/Piping Protection for Temporary Cuts Cuts in sandy advance outwash sediments may be prone to localized erosion due to seepage if encountered. During earthwork, areas determined by the project geotechnical engineer or geologist to be potentially unstable due to seepage/erosion may require removal of the unstable/saturated soil and placement of a stabilizing rock blanket. If necessary, a rock blanket would typically consist of a minimum 2-foot-thick prism of 2-to 4-inch-sized crushed quarry rock embedded in the seepage zone. A layer of filter fabric (Mirafi 140N, or equivalent) should be provided between the rock and the subgrade soil to prevent the migration of fines through the rock. The requirement for and extent of rock protection for seepage zones can be determined in the field during site earthwork as seepage areas are exposed. In general, late, dry season construction is anticipated to minimize the seepage quantities and the requirements for erosion/piping protection. 9.3 Site Disturbance A portion of the on-site soils contains a high percentage of fine-grained material which makes them moisture-sensitive and subject to disturbance when wet. The contractor must use care during site preparation and excavation operations so that the underlying soils are not softened. If disturbance occurs, the softened soils should be removed and the area brought to grade with structural fill. Consideration should be given to protecting any unpaved access and staging areas with an appropriate section of crushed rock or asphalt treated base (A TB). If crushed rock is used for the access and staging areas, it should be underlain by engineering stabilization fabric to reduce the potential of fine-grained materials pumping up through the rock and turning the area to mud. The fabric will also aid in supporting construction equipment, thus reducing the amount of crushed rock required. We recommend that at least 10 inches of rock be placed over the fabric; however, due to the variable nature of the near- February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

No information regarding the pavement section existing along the east, west, and south sides of the proposed building area was available to AESI as of the date of this report. It is considered likely that repetitive heavy loading such as that anticipated by construction traffic, including loaded dump trucks, could cause damage to existing pavement. Repair of these areas as necessary should be included in construction scope and budgets. 10.0 SHORING -SOLDIER PILE WALLS To achieve design daylight basement elevation, an excavation ranging in depth to 20 feet is currently anticipated for this project. Some form of temporary shoring will be required to support the temporary excavation where open cuts in conformance with recommended gradients are not feasible. This section of the report presents preliminary design considerations and criteria which should be considered in the design of the shoring for the excavation. With this information and other pertinent data, it should be the responsibility of the shoring subcontractor(s) to determine the appropriate design, construction methods, and procedures for installation of the shoring system. The most common method of shoring used in the area consists of a conventional soldier pile/waler shoring system utilizing steel soldier piles, sometimes in conjunction with an internally braced or tieback system. Soldier piles, which are wide-flange beams, are placed in pre-drilled holes which extend beyond the bottom of the excavation. The portion of each soldier pile extending below the bottom of the excavation is grouted in place with sufficient- strength concrete to transmit the vertical loads of the soldier beams to the soil below the excavation level. The upper portion of the soldier pile is then backfilled with a relatively weak grout so that it may be removed for placement of lagging. We recommend that lagging be backfilled with sand slurry pumped into place behind shoring walls to minimize the potential for movement of the cut soil. 10.1 Shoring Wall Retained Earth Pressures For cantilever walls, we recommend that the shoring system be designed to withstand lateral soil pressures based on "active" conditions. This design pressure, based on a level backfill, is in the form of an equivalent fluid equal to 35 pounds per cubic foot (pet) triangular distribution acting over the pile spacing above the excavation level. Below the level of excavation, the 35 pef may be considered to act only over the dianleter of the grouted soldier pile section. Any applicable surcharges from adjacent structures, stockpiled materials, construction equipment, or sloping ground must be added to the above values. Where supporting a backslope of 1.5H:IV, an equivalent fluid equal to 60 pef triangular distribution may be used. Again, February 8, 2005 ASSOCIATED EARTH SCIENCES. INC.

The use of active pressure for the shoring system assumes sufficient deformation if the soil occurs to develop an active condition --typically on the order of 0.001 to 0.002 times the height of the excavation. Any settlement-sensitive structures should be set back a minimum horizontal distance equal to the shoring wall height so that wall deflections/soil movement do not impact adjacent foundations. A combination of temporary 1. 5H: 1 V slopes and shoring may be utilized to reduce the overall height of shoring. Once the shoring/slope configuration is developed, AESI should be consulted to review the design parameters, as necessary. IO.2 Shoring Wall Passive Earth Pressure The soldier piles must be located a sufficient depth below the base of the excavation to provide adequate lateral resistance to horizontal loads. The lateral resistance may be computed on the basis of passive pressure in the form of an equivalent fluid equal to 300 pcf. The upper 2 feet of passive soil resistance should be ignored due to disturbance. This pressure may be considered to be acting against twice the diameter of the grouted soldier pile section. Piles should extend at least 10 feet below the excavation level. 10.3 Shoring Inspections Shoring installation should be observed by a representative of AESI to verify that subsurface conditions are as anticipated and that the shoring elements are installed in conformance with the shoring plan. Inspections should include pile installation, excavation and lagging placement, lagging backfill, and drainage. Survey monitoring of the piling and adjacent structures may also be required. IO.4 Tiebacks Tieback anchors may be used to aid in resisting lateral loading on the shoring system. A tieback system consists of drilling behind the soldier pile wall at an angle to the horizontal and installing rods or cables with a grout anchor. The anchor loads are transmitted to the surrounding soil by side friction or adhesion with the soil If requested, recommendations for design and testing of tieback anchors can be provided. 11.0 STRUCTURAL FILL Structural fill will be necessary for wall backfill. utility backfill, and beneath hardscape.

Proposed Classroom/Maintenance Building (Building N) Renton Technical College Renton, Washington Subsuiface Exploration, Geologic Hazards, and Preliminary Geotechnical Engineering Report Design Recommendations and compaction of materials as discussed in this section. If a percentage of compaction is specified under another section of this report, the value given in that section should be used. If fill is to be placed on slopes steeper than 5H:lV, the base of the fill should be tied to firm, stable subsoil by appropriate keying and benching which would be established in the field to suit the particular soil conditions at the time of grading. The keyway will act to embed the toe of the new fill into the hillside. Generally, the keyway for hillside fills should be at least 4 feet wide and cut into medium dense sand or stiff silt. Level benches would then be cut horizontally across the hill, following the contours of the slope. No specific width is required for the benches, although they are usually at least 4 feet wide. All fills proposed over a slope should be reviewed by our office prior to construction. After stripping, planned excavation, and any required overexcavation have been performed to the satisfaction of the geotechnical engineer/engineering geologist, the exposed ground should be recompacted to 90 percent of the modified Proctor maximum density using ASTM:D 1557 as the standard. If the subgrade contains too much moisture, adequate recompaction may be difficult or impossible to obtain and should probably not be attempted. In lieu of recompaction, the area to receive fill should be blanketed with washed rock or quarry spalls to act as a capillary break between the new fill and the wet subgrade. Where the exposed ground remains soft and further overexcavation is impractical, placement of an engineering stabilization fabric may be necessary to prevent contamination of the free-draining layer by silt migration from below . After recompaction of the exposed ground is tested and approved, or a free-draining rock course is laid, structural fill may be placed to attain desired grades. Structural fill is defined as non-organic soil, acceptable to the geotechnical engineer, placed in maximum 8-inch loose lifts with each lift being compacted to 95 percent of the modified Proctor maximum density using ASTM:D 1557 as the standard. The top of the compacted fill should extend horizontally outward a minimum distance of 3 feet beyond the location of footings or pavement edges before sloping down at an angle of2H:IV. The contractor should note that any proposed fill soils must be evaluated by AESI prior to their use in fills. This would require that we have a sample of the material 72 hours in advance to perform a Proctor test and determine its field compaction standard. Soils in which the amount of fme-grained material (smaller than the No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) should be considered moisture-sensitive. Use of moisture-sensitive soil in structural fills should be limited to favorable dry weather conditions. The on-site soils generally contained significant amounts of silt and are considered moisture-sensitive. In addition, construction equipment traversing the site when the soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained, a select import material consisting of a clean, free-draining gravel and/or sand should be used. Free-draining fill consists of non-organic soil with the February 8, 2005 ASSOCIATED EARTH SCIENCES, INC. MTI/s -KE04752A2 -Projecls120047521KEIWP Page 19 I I I I i I I !

An AESI representative should inspect the stripped sub grade and be present during placement of structural fill to observe the work and perform a representative number of in-place density tests. In this way, the adequacy of the earthwork may be evaluated as filling progresses and any problem areas may be corrected at that time. It is important to understand that taking random compaction tests on a part-time basis will not assure uniformity or acceptable performance of a fill. As such, we are available to aid the owner in developing a suitable monitoring and testing frequency. 12.0 FOUNDATIONS Spread footings may be used for building support when founded directly on suitable advance outwash soil or on structural fill placed as previously discussed. Footings founded on suitable advance outwash sand or on structural fill above the advance outwash sand may be designed for an allowable foundation soil bearing pressure of 3,000 pounds per square foot (pst) including both dead and live loads. An increase of one-third may be used for short-term wind or seismic loading. All foundations must penetrate to the prescribed bearing stratum and no foundations should be constructed in or above loose, organic, or existing fill soils. In addition, all footings must have a minimum width of 18 inches . Perimeter footings should be buried at least 18 inches below lowest adjacent grade for frost protection; interior footings require only 12 inches burial. Considering the granular nature of the site soils, settlements are expected to be small and occur rapidly during the initial application of dead load. Anticipated settlement of footings founded as described above should be on the order of ')4 inch with differential movement about half of that total. However, disturbed soil not removed from footing excavations prior to footing placement could result in increased settlements. Installation of settlement-sensitive surfaces should be delayed as long as practical. All footing areas should be inspected by AESI prior to placing concrete to verify that the design bearing capacity of the soils has been attained and that construction conforms to the recommendations contained in this report. The City of Renton may require such inspections. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. . It should be noted that the area bounded by lines extending downward at IH: IV from any footing must not intersect another footing or intersect a filled area that has not been compacted to at least 95 percent of ASTM:D 1557. In addition, a 1.5H: 1 V line extending down from any footing must not daylight because sloughing or raveling may eventually undermine the footing. Thus, footings should not be placed near the edge of steps or cuts in the bearing soils. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

I Proposed Classroom/Maintenance Building (Building N) Renton Technical College Renton, Washington 13.0 LATERAL WALL PRESSURES Subsulface Exploration. Geologic Hazards. and Preliminary Geotechnical Engineering Report Design Recommendations All backfill behind walls or around foundation units should be placed as per our recommendations for structural fill and as described in this section of the report. Horizontally backfilled walls which are free to yield laterally at least 0.1 percent of their height may be designed using an equivalent fluid equal to 35 pcf. Fully restrained, horizontally backfilled rigid walls which cannot yield should be designed for an equivalent fluid of 55 pcf. Where driveway or parking areas are adjacent to walls, a surcharge equivalent to 2 feet of soil should be added to the wall height in determining lateral design forces. The lateral pressures presented above are based on the conditions of a uniform, level backfill consisting of free-draining soil compacted to 90 percent of ASTM:D 1557. A higher degree of compaction is not recommended as this will increase the pressure acting on the wall. A lower compaction may result in settlement of any slab-on-grade or other structures above the walls. Thus, the compaction level is critical and must be tested by our firm during placement. Surcharges from adjacent footings, heavy construction equipment, or sloping ground must be added to the above values. Footing drains should be provided for all retaining walls as discussed under the section on Drainage Considerations. It is imperative that proper drainage be provided so that hydrostatic pressures do not develop against the walls. This would involve installation of a minimum I-foot-wide blanket drain to within 1 foot of the top of the wall using imported, washed gravel against the walls. Less permeable on-site soil may be used as a cap over the gravel. Filter fabric (Mirafi 140N, or equivalent) should be placed over the gravel drain prior to soil cap placement to reduce the potential for migration of fines. 13.1 Passive Resistance and Friction Factors Retaining wall footings/keyways cast directly against undisturbed, dense outwash sediments in a trench may be designed for passive resistance against lateral translation using an equivalent fluid equal to 300 pcf. The passive equivalent fluid pressure diagram begins at the top of the footing; however, total lateral resistance should be summed only over the depth of the actual key (truncated triangular diagram). These values apply only to footings/keyways where concrete is placed directly against the trench sidewalls without the use of forms. If footings are placed on suitable advance outwash sediments and then backfilled, the top of the compacted backfill must be horizontal and extend outward from the footing for a minimum lateral distance equal to three times the height of the backfill before tapering down to grade. With backfill placed as discussed, footings may be designed for passive resistance against lateral translation using an equivalent fluid equal to 250 pcf and the truncated pressure diagram discussed above. Passive resistance values include a factor of safety equal to 3 in order to reduce the amount of movement necessary to generate passive resistance . February 8. 2005 ASSOCIATED EARTH SCIENCES. INC.

Geologic Hazards. and Preliminary Geotechnical Engineering Report Design Recommendalions The friction coefficient for footings cast directly on undisturbed, dense outwash sediments or structural fill may be taken as 0.35. This value includes a safety factor of at least 1.5. 14.0 FLOOR SUPPORT The slab-on-grade floor may be founded on structural fill or unweathered outwash sediments. The floor should be cast atop a minimum of 4 inches of washed pea gravel to act as a capillary break. It should also be protected from dampness by a minimum lO-mil-thick vapor retarder membrane. 15.0 DRAINAGE CONSIDERATIONS All retaining and perimeter footing walls should be provided with a drain at the footing elevation. Drains should consist of minimum 6-inch-diameter, rigid, perforated, polyvinyl chloride (PVC) pipe surrounded by washed pea gravel. The level of the perforations in the pipe should be at least 12 inches below the bottom of the floor slab and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. Footing drains should be provided with cleanouts to allow periodic future cleaning/maintenance . All retaining walls should be lined with a minimum 12-inch-thick washed gravel blanket to within 1 foot of the top of the wall and which ties into the footing drain. Less permeable on- site soil may be used as a cap over the gravel. Filter fabric should be placed over the gravel prior to soil cap placement to reduce the potential for migration of fines into the wall drain. Roof and surface runoff should not discharge into the footing drain system but should be handled by a separate, rigid, tightline drain. In planning, exterior grades adjacent to walls should be sloped downward away from the structure (minimum 2 percent slope) to achieve surface drainage. 16.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, site grading, structural plans, and construction methods have not been finalized and the recommendations contained herein are preliminary. We are available to provide additional geotechnical consultation as the project design develops and possibly changes from that upon which this report is based. We recommend that AESI perform a geotechnical review of the plans prior to final design completion. In this way, our earthwork and foundation recommendations may be properly interpreted and implemented in the design. February 8. 2005 ASSOCIATED EARTH SCIENCES. INC.

PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and preliminary geotechnical engineering study for the proposed Maintenance/Classroom Building (Building N) within the Renton Technical College campus located at 3000 NE 4"' Street, Renton, Washington. The general location of the site is depicted on the Vicinity Map, Figure 1. The proposed building location and approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 2. Our recommendations are preliminary in that site grading, structural plans, and construction methods have not been finalized at the time of this report. In the event that any changes in the nature, design, or location of the structure are planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1. 1 Purpose and Scope The purpose of this study was to provide subsurface data to be utilized in the preliminary design and development of the subject project. Our study included a review of available geologic literature, excavating an exploration pit, drilling an exploration boring, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments and shallow ground water conditions. Infiltration testing was conducted within the exploration pit. Geologic hazard evaluations and geotechnical engineering studies were also conducted to determine suitable geologic hazard mitigation techniques, the type of suitable foundation, allowable foundation soil bearing pressures, anticipated settlements, temporary slope/shoring recommendations, basement/retaining wall lateral pressures, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and offers hazard mitigation, development, and infiltration recommendations based on our present understanding of the project. 1.2 Authorization Authorization to proceed with this study was granted by Ms. Sally MacGregor of S.M. Stemper Architects, PLLC. Our study was accomplished in general accordance with our proposal letter dated November 24, 2004. This report has been prepared for the exclusive use of the Renton Technical College, S.M. Stemper Architects, PLLC, and their agents for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. It must be understood that no recommendations February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner. 2.0 PROJECT AND SITE DESCRlPTION This report was completed with an understanding of the project based on the site plan dated September 30, 2004 (revised October 18, 2004) prepared by Coughlin Porter Lundeen. Present plans call for a two-story structure with daylight basement with slab-on-grade floors planned for the basement area of the building. The lowest level will be set at the same elevation as westerly adjacent Building L. The second floor of the proposed new building will be at approximately the same elevation as the easterly adjacent parking area. New access stairs and a courtyard retaining wall are planned along the south end of the proposed building. The property is situated at 3000 NE 4th Street in Renton, Washington and is the site of Renton Technical College. The proposed new building will be situated within the northeastern portion of the school campus. An asphalt concrete access drive/parking area extends along the western edge of the proposed building area. A moderate, 15-to 20-foot high, grass-covered slope descends across the proposed building area from the east parking lot to the west access drive/parking area. A rockery wall extends north-south along the toe of the slope. The existing site slope is considered by the City of Renton code to be a "Medium Landslide Hazard," which is defined ~n the Renton Municipal Code, Chapter 3, Section 4-3-050, paragraph 4.c.ii as "Areas with slopes between fifteen percent (15%) and forty percent (40%) and underlain by soils that consist largely of sand, gravel or glacial till." Based on topographic information provided to us, the overall slope gradient measured from top to toe of slope is approximately 20 to 25 percent (5H:IV [Horizontal:VerticaIJ to 4H:IV). As proposed, site development will require temporary cuts to a height of approximately 20 feet along the easterly adjacent parking area. Where space limitations result in temporary excavations steeper or higher than recommended herein, shoring will. be required. The actual location and configuration of the temporary cut will factor into the determination regarding how much and where shoring will be required. 3.0 SUBSURFACE EXPLORATION Our field study included drilling one exploration boring, excavating one exploration pit, performing infiltration testing, and conducting geologic and geologic hazard reconnaissance to gain information about the site. The various types of sediments, as well as the depths where characteristics of the sediments changed, are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed may represent gradational variations between sediment types in the field.

Our explorations were approximately located in the field by estimation from known site features shown on the referenced site plan by Coughlin Porter Lundeen. The conclusions and recommendations presented in this report are based on subsurface conditions revealed in the exploration boring and exploration pit completed for this study. The number, location, and depth of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. It should be noted that differing subsurface conditions may sometimes be present due to the random nature of deposition and the alteration of topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. 3.1 Exploration Boring The exploration boring was completed by advancing a 3'/8-inch, inside-diameter, hollow-stem auger with a track-mounted drill rig. During the drilling process, samples were obtained at generally 2.5-or 5.0-foot depth intervals. The boring was continuously observed and logged by a geotechnical engineer from our firm. The exploration log presented in the Appendix is based on the field log, drilling action, and inspection of the samples secured. Disturbed but representative samples were obtained by using the Standard Penetration Test (SPT) procedure in accordance with American Society for Testing and Materials (ASTM):D 1586. This test and sampling method consists of driving a standard, 2-inch, outside-diameter, split-barrel sampler a distance of 18 inches into the soil with a 140-pound hammer free-falling a distance of 30 inches. The number of blows for each 6-inch interval is recorded and the number of blows required to drive the sampler the final 12 inches is known as tbe Standard Penetration Resistance ("N") or blow count. If a total of 50 is recorded within one 6-inch interval, the blow count is recorded as the number of blows for the corresponding number of inches of penetration. The resistance, or N-value, provides a measure of the relative density of granular soils or the relative consistency of cohesive soils; these values are plotted on the attached boring log. The samples obtained from the split-barrel sampler were classified in the field and representative portions placed in watertight containers. The samples were then transported to our laboratory for further visual classification and laboratory testing, as necessary. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

The exploration pit permitted direct, visual observation of subsurface conditions. Materials encountered in the exploration pit were studied and classified in the field by a geotechnical engineer from our firm. A Pilot Infiltration Test (PIT) was conducted at a depth of approximately 3.5 feet in the exploration pit. Upon completion of the test, the pit was excavated to a depth of 12 feet. The exploration pit was backfilled immediately after examination and logging. Selected samples recovered from the exploration were transported to our laboratory for further visual classification and testing, as necessary. 3.3 Infiltration Testing An infiltration test was conducted at a depth of approximately 3.5 feet below existing ground surface in EP-I in the vicinity of the proposed storm water management structure adjacent to the southwest corner of the proposed maintenance/classroom building. The infiltration testing was conducted using a method generally corresponding to the procedure described for the Pilot Infiltration Test (PIT) in the Washington State Department of Ecology 2001 Stormwater Management Manual for Western Washington (Ecology manual). This test is conducted by discharging water into a flat-bottomed pit of known dimensions for a 4-hour "soaking period" to allow the receptor soils in the immediate vicinity of the pit to become saturated. After completion of the soaking period, water is discharged into the pit at a rate sufficient to maintain a head in the pit. This is continued until the discharge rate required to maintain a constant head remains fairly consistent over a period of I hour. Ground water infiltration was conducted inside a large-diameter (72-inch-diameter) iron ring embedded into the unweathered advance outwash soil. The large-diameter ring was used in lieu of the open pit described in the Ecology Manual to avoid or reduce testing errors due to such factors as sidewall collapse, inaccurate measurement of open pit areas, and sidewall infiltration. The water source used for the test consisted of a fire hydrant located adjacent to the southwest portion of the proposed building area. Water was discharged into the pit through a fabric diffuser to minimize turbulence and scouring of the pit bottom. A flow meterltotalizer was used to monitor the water discharge rate and total flow. A staff gauge with O.OI-foot divisions was installed in the pit to monitor the depth of water during testing. For the constant head test, a head of approximately 0.80 feet was maintained in the pit. Following completion of the constant-head test, the flow of water into the pit was discontinued and the rate of water level decline (falling head) in the pit was monitored. All infiltration test data was recorded by hand in the field and subsequently transferred to an electronic spreadsheet to allow more accurate and consistent infiltration rate calculations. The infiltration testing results are summarized below in Table I. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

This is typical and is reflective of the decreasing head in the pit below that maintained during the constant head test.

Exploration boring EB-l was drilled within the higher elevation, eastern portion of the site; exploration pit EP-l was excavated at the toe of the slope, southwesterly adjacent to the proposed structure. As shown on the field logs, exploration boring EB-l encountered approximately 2 feet of relatively loose sandy fill overlying medium dense to dense sand and February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Exploration pit EP-l encountered approximately 1 foot of loose to medium dense sand fill over medium dense to dense, stratified, fine to coarse sand with a trace of silt to the bottom of the pit at 12 feet. The following sections present more detailed subsurface information. 4.1 Stratigraphy Fill Fill soils (those not naturally placed) were encountered to a depth of approximately 2 feet in exploration boring EB-I and to a depth of approximately 1 foot in EP-l. Based on the classification of the native soils encountered on-site, it is considered likely that the fill soil was derived from on-site sources and placed during one of the phases of earlier site development. The fill generally consisted of a loose mixture of silt and sand. The fill soils as observed are considered unsuitable for support of the proposed structure. Existing fill soil may be considered for use as structural fill where moisture-conditioned and compacted as recommended in the Structural Fill Section of this report. Fill depth may vary across the proposed building area. Advance Outwash Below the fill, a medium dense to dense, stratified mixture of fine to coarse sand with a trace of silt interpreted as advance outwash was encountered. Advance outwash sediments were deposited as outwash from rivers flowing from the base of the southward advancing glacial front. The advance outwash has been overridden by several thousand feet of ice resulting in a compact, competent soil mass. This process resulted in a compact soil possessing high strength and relatively low compressibility characteristics. The medium dense to dense advance outwash is considered to be suitable for foundation support. The advance outwash soil may be used as structural fill where moisture-conditioned and compacted as detailed in the Structural Fill Section of this report. 4.2 Hydrology No ground water/seepage was encountered in our explorations. It should be noted that fluctuations in the level of the ground water may occur due to the time of the year, variations in rainfall, irrigation, on-and off~site land usage, and other factors. 4.3 Site Infiltration The Ecology Manual defines three methods for determining long-term infiltration rate. The methods are identified in the following paragraphs and results, as related to the project site, are presented. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC. MTlts -KE04752A2 -Projeclsl2004752lKEIWP Page 6 I I I I I I I I I I I I I Proposed Maintenance/Classroom Building (Building N) Renton Technical Col/ege Renton, Washington Method I Subsurface Exploration, Geologic Hazards, and Preliminary Geotechnical Engineering Report Project and Site Conditions The results of grain size analyses conducted on soil samples obtained from EP-I excavated in the vicinity of the proposed storm water facility indicate a silt content ranging between 0.6 and 4.7 percent. Using the United States Department of Agriculture (USDA) Textural Triangle presented as Figure 7.1 in the Ecology Manual, the texture of the samples tested is determined to be sand. Using this texture classification in conjunction with Table 7.1 in the Ecology Manual, an estimated long-term (design) infiltration rate of 2 inches per hour is an allowable estimation for site soils. Method 2 Method 2 presented in the Ecology Manual allows estimation of long-term (design) infiltration rate directly from soil gradation data. This method requires a determination of the effective size of the grains comprising the soil. The effective size (DlO) is defined as the size corresponding to lO percent on the grain size curve. The effective size of soil within samples obtained from the site ranges from 0.1 (EP-l at 3 to 5.5 feet) to 0.33 (EP-I at 5.5 to 11 feet). Using the effective size determined for samples tested and Table 7.2 presented in the Ecology Manual, the corresponding estimated long-term (design) infiltration rate for site soil ranges from 2 to 6.5 inches per hour. Method 3 As described in Section 3.3 Infiltration Testing, a PIT was conducted in general conformance with Method 3 presented in the Ecology Manual. Test results are presented in Table 2. Infiltration Design (Long-Term) Rate As indicated on the log of EP-I, the upper 5.5 feet of soil in the vicinity of the infiltration test consisted of sand with a trace of silt. Soil below 5.5 feet consisted of stratified fine to coarse sand. The PIT was conducted at a depth of 3.5 feet in the sand with a trace of silt. Based on the results of grain size testing, it is considered likely that a higher infiltration rate would have been observed had the PIT been conducted within the sand soil encountered at a lower elevation. Based on this and the long-term infiltration rate determined by Methods 1 and 2, it is our opinion that the infiltration rate determined during the PIT is roughly representative of infiltration rates to be expected over the design life of the proposed infiltration structure, thus, we recommend the following long-term infiltration rate.

The reconunended design infiltration rate is based on the soil characteristics at the infiltration test location. Soil conditions may vary outside the area tested. Soil characteristics for infiltration facilities constructed outside of the test location should be evaluated by Associated Earth Sciences, Inc. (AESI) to verify whether or not the maximum recommended design infiltration rate is suitable. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Washington SubsUlface Exploration. Geologic Hazards. and Preliminary Geotechnical Engineering Repon Geologic Hazards and Mitigations II. GEOLOGIC HAZARDS AND MITIGATIONS The following discussion of potential geologic hazards is based on the geologic, slope, and ground water conditions as observed and discussed herein. The discussion will be limited to seismic, landslide or mass-wasting, and erosion, including sediment transport. 5.0 SEISMIC HAZARDS AND RECOMMENDED MITIGATION Earthquakes occur in the Puget Lowland with great regularity. The vast maJonty of these events are small and are usually not felt by people. However, large earthquakes do occur as evidenced by the 1949, 7.2-magnitude event; the 1965, 6.S-magnitude event; and the 2001 6.9- magnitude event. The 1949 earthquake appears to have been the largest in this area during recorded history. Evaluation of earthquake return rates indicates that an earthquake of the magnitude between 5.5 and 6.0 is likely within a given approximate 20-year period. Generally, there are four types of potential geologic hazards associated with large seismic events: 1) surficial ground rupture; 2) liquefaction; 3) ground motion; and 4) seismically induced landslides. The potential for each of these hazards to adversely impact the proposed project is discussed below. 5.1 Surficial Ground Rupture Generally, the largest earthquakes which have occurred in the Puget Sound area are sub-crustal events with epicenters ranging from 50 to 70 kilometers in depth. For this reason, no surficial faulting or earth rupture as a result of seismic activity has been documented to date within at least 5 miles of the site. Therefore, it is our opinion, based on existing geologic data, that the risk of surface rupture impacting the proposed project is low and no mitigations are necessary. 5.2 Liquefaction Liquefaction is a process through which unconsolidated soil loses strength as a result of vibratory shaking, such as that which occurs during a seismic event. During normal conditions, the weight of the soil is supported by both grain-to-grain contacts and by the pressure within the pore spaces of the soil below the water table. Extreme vibratory shaking can disrupt the grain-to-grain contact, increase the pore pressure, and result in a decrease in soil shear strength. The soil is said to be liquefied when nearly all of the weight of the soil is supported by pore pressure alone. Liquefaction can result in deformation of the sediment and settlement of overlying structures. Areas most susceptible to liquefaction include those areas underlain by coarse silt and sand with low relative densities, accompanied by a shallow water table.

Washington Subsurface Exploration. Geologic Hazards. and Preliminary Geotechnical Engineering Report Geologic Hazards and Mitigations The majority of the soils encountered in our explorations were in a medium dense to dense condition and therefore do not present a significant liquefaction hazard. Based on soil density and the absence of ground water, site soils are considered to have a low potential for liquefaction. 5.3 Ground Motion The project site is located within a Zone 3 rating for seismic activity on a scale of 1 (lowest) to 4 (highest) based on the Seismic Zone Map of the United States, Figure No. 16-2 in the 1997 edition of the Uniform Building Code (UBC). This zonation is based on past earthquake activity in the Puget Sound region. As such, design recommendations in the report accommodate the possible effect of seismic activity in areas with a Zone 3 rating corresponding to a peak ground acceleration of 0.3g (a Richter magnitude 7.5 earthquake occurring directly beneath the site) in accordance with UBC guidelines. Based on site stratigraphy and visual reconnaissance of the site, it is our opinion that any earthquake damage to the proposed structure founded on suitable bearing strata would be caused by the intensity and acceleration associated with the event and not any of the impacts discussed in the Seismic Hazards and Recommended Mitigation section of this report. Structural design of the building should take into consideration stress caused by seismically induced earth shaking. Due to the thickness and consistency of the sediments underlying the site, amplification of seismic motion upward through this soil column is possible. The approximate proposed building period should be compared to the estimated soil column period of vibration to check for resonant conditions. It is these conditions that result in our recommendation for the more stringent SD soil type classification for use with the UBC standards and Site Class 0 for use with the International Building Code (!BC) as discussed below. Guidelines presented in the 2003 IBC, Section 1615, may be used. Information presented in Figure 1615(1) indicates a mapped spectral acceleration for short periods of S, = 1.37. Information presented in Figure 1615(2) indicates a mapped spectral acceleration for a 1 second period of S, = 0.47. Based on the results of subsurface exploration and on an estimation of soil properties at depth utilizing available geologic data, Site Class "0" in conformance with Table 1615.1.1 may be used. Site coefficients F. = 1.0 and F, = 1.5 in conformance with!BC Tables 1615.1.2(1) and 1615(2), respectively, may be used. 5.4 Seismically Induced Landslides The existing slope within the building area is to be removed and replaced with a retaining wall as a part of site development. Therefore, the potential risk of seismically induced landslides February 8. 2005 ASSOCIATED EARTH SCIENCES. INC.

No mitigations are recommended regarding seismically induced landslides. Slope stability is discussed further in the following section. 6.0 LANDSLIDE HAZARDS AND MITIGATION Generally, there are two types of landslides that commonly occur in the Puget Sound region. The first type is termed Earth Slump or Slump-Earth Flow. This type of earth movement is deep-seated and usually involves the regolith (topsoil) and the underlying sedimentary units. Slides of this type can be very large. The second type is termed Debris Slump or Debris Flow and usually involves the upper few feet of the regolith. This type of slide is very dependent on local drainage patterns and the resulting moisture content of the soils. Based on the site stratigraphy and visual geologic reconnaissance, the slope areas appear to be more susceptible to a shallow debris flow due to the presence of the glacially consolidated, advance outwash soil encountered below the surficially disturbed fillltopsoil horizon. A slope stability analysis was beyond the scope of this study, and therefore, the stability risks cannot be quantified by this study. However, it is our opinion that the seismic and static factors of safety would lie within generally accepted limits and that the deep-seated landslide risks on the site are low under both static and seismic conditions. The proposed development should not increase the risk of deep-seated movements provided the recommendations presented in this report are followed. As discussed earlier in this report, proposed development will eliminate the existing slope within the building area and will eliminate the potential risk of landslides affecting the proposed structure. Slopes will remain north and south of the proposed structure and adjacent to pedestrian walkways. Based on observed evidence of weathering and disturbance due to burrowing rodents, it is our opinion that shallow movement on the slope areas to remain north and south of the proposed structure presents a low risk under current site conditions. Since local drainage, slope steepness, slope height, and vegetation cover largely influence the shallow stability and soil erosion, the planned development will require specific mitigation measures to avoid increasing the shallow earth movement risk. These mitigations include controlling runoff, establishing vegetation cover, and following the recommendations as outlined in this report. In our opinion, by following these recommendations, the risk of shallow earth movement on the site or on surrounding properties will not be increased by the proposed construction.

Erosion hazard areas are classified as having moderate to severe, severe, or very severe erosion potential by the Soil Conservation Service, United States Department of Agriculture (USDA). " Soils in the vicinity of the project are mapped by the USDA as Alderwood, gravelly sandy loam on slopes of 6 to 15 percent. Site-specific information from explorations is in general agreement with USDA mapping. Some areas of Alderwood soils on slopes of 15 to 30 percent may be encountered, but are not mappable at the USDA map scale. Surface runoff and erosion hazards soil characteristics of these soil types are presented in Table 4. Table 4 Surface Runoff and Erosion Hazard Soil Characteristics Soil Type Percent Slope Surface Runoff Erosion Hazard Alderwood 6 to 15 Medium Moderate Alderwood 15 to 30 Medium to Rapid Moderate to Severe The on-site soils contain a significant amount of fines and are considered moisture-sensitive. Therefore, all permanent and temporary slopes should be protected from erosion. The following general erosion mitigation measures are recommended for use throughout the site. 1. All storm water from impermeable surfaces should be tightlined into approved storm water drainage systems. 2. To reduce the amount of sediment transport from the proposed construction area, silt fencing should be placed along the lower elevations of the cleared areas. 3. Temporary sediment catchment facilities, interceptor drainage swales, and surface conveyance swales should be installed to intercept runoff and eroded sediment prior to site work. Check dams should be installed as necessary. 4. Earthwork should proceed during the drier summer periods of the year and disturbed areas should be revegetated as soon as possible. Temporary erosion control measures should be maintained until permanent erosion control measures are established. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

All devices used to collect surface runoff should be directed into a tightline or swale system designed to convey the collected drainage to discharge within an approved storm drain system. 6. Soils that are to be reused around the site should be stored in such a manner as to reduce erosion. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, the use of low stockpiles in flat areas, or the use of straw bales/silt fences. 7. Prior to the onset of winter, any exposed subgrade should be hydroseeded, covered with plastic sheeting, or otherwise protected. Seed should be planted soon enough to have the grass established by October 31. If suitable ground cover vegetation is not established prior to the wet season, mulch cover or plastic sheeting should be used. 8. At the end of each workday, disturbed areas should be sloped to drain into a storm conveyance and seal-rolled to promote surface drainage. 9. A temporary, rock-surfaced construction entrance and staging areas should be established early in the project sequence. 10. All storm water from impermeable surfaces, induding driveways and roofs, should be tightlined into approved facilities and not be directed onto or above steeply sloping areas. 11. As much of the natural vegetation on the slopes as is possible should be left intact during construction. Sloping areas without sufficient vegetation and areas stripped of vegetation during construction should be planted as soon as possible or otherwise protected. 12. Erosion control measures should be inspected regularly and maintained/improved as necessary to maintain function. 13. The surface of the slopes to remain adjacent to the proposed building and associated hardscape should be scarified, moisture-conditioned as necessary, and compacted. The resulting slope gradient should be as uniform as possible and should match that of the surrounding areas. 14. Regular pest control services should be employed to maintain the site free of burrowing rodents. FebrUflry 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

DESIGN RECOMMENDATIONS 8.0 INTRODUCTION Our exploration indicates that, from a geotechnical standpoint, the project area is suitable for the proposed development provided that the recommendations contained herein are properly followed. It is our understanding that column loads will be on the order of 100 to 150 kips. Subsurface conditions disclosed by our explorations revealed medium dense to dense advance outwash sediments at a depth of approximately I to 2 feet below existing ground surface. Given the loose nature of the fill and disturbed ad vance outwash soil, it is not recommended for support of building foundations. The existing fill and disturbed advance outwash materials may be suitable for reuse as structural fill provided the moisture content is maintained within the compactable range. Site development will require temporary cuts to a height of 20 feet (maximum) along the eastern, northern, and southern perimeters of the proposed structure. Where space limitations result in temporary excavations steeper or higher than recommended herein, shoring will be required. The actual location and configuration of the temporary cut will be factors in how much and where shoring will be required. Recommendations are presented in the Shoring - Soldier Pile Walls section of this report. 9.0 SITE PREPARATION Site preparation within the planned building area should include removal of all trees, landscape structures, pavements, brush, debris, and any other deleterious material. Additionally, any organic topsoil should be removed and the remaining roots grubbed. Any buried structures andlor utilities should be removed or relocated if they are encountered underlwithin the area to be developed. The resulting depressions that extend below or outside the planned excavation envelope should be backfilled with structural fill as discussed under the Structural Fill section of this report. 9.1 Temporary Cut Slopes In our opinion, stable construction slopes should be the responsibility of the contractor and should be determined during construction based on the conditions encountered at a particular location and time. For estimating purposes, however, we anticipate that temporary, unsupported cut slopes in the sandy fill and advance deposit soil can be planned at a maximum slope of 1.5H: 1 V. To provide additional protection, the top of a cut slope should begin no February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Recommendations are presented in the Shoring -Soldier Pile Walls section of this report. 9.2 Erosion/Piping Protection for Temporary Cuts Cuts in sandy advance outwash sediments may be prone to localized erosion due to seepage if encountered. During earthwork, areas determined by the project geotechnical engineer or geologist to be potentially unstable due to seepage/erosion may require removal of the unstable/saturated soil and placement of a stabilizing rock blanket. If necessary, a rock blanket would typically consist of a minimum 2-foot-thick prism of 2-to 4-inch-sized crushed quarry rock embedded in the seepage zone. A layer of filter fabric (Mirafi 140N, or equivalent) should be provided between the rock and the subgrade soil to prevent the migration of fines through the rock. The requirement for and extent of rock protection for seepage zones can be determined in the field during site earthwork as seepage areas are exposed. In general, late, dry season construction is anticipated to minimize the seepage quantities and the requirements for erosion/piping protection. 9.3 Site Disturbance A portion of the on-site soils contains a high percentage of fine-grained material which makes them moisture-sensitive and subject to disturbance when wet. The contractor must use care during site preparation and excavation operations so that the underlying soils are not softened. If disturbance occurs, the softened soils should be removed and the area brought to grade with structural fill. Consideration should be given to protecting any unpaved access and staging areas with an appropriate section of crushed rock or asphalt treated base (ATB). If crushed rock is used for the access and staging areas, it should be underlain by engineering stabilization fabric to reduce the potential of fine-grained materials pumping up through the rock and turning the area to mud. The fabric will also aid in supporting construction equipment, thus reducing the amount of crushed rock required. We recommend that at least 10 inches of rock be placed over the fabric; however, due to the variable nature of the near- Februnry 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

No information regarding the pavement section existing along the east, west, and south sides of the proposed building area was available to AESI as of the date of this report. It is considered likely that repetitive heavy loading such as that anticipated by construction traffic, including loaded dump trucks, could cause damage to existing pavement. Repair of these areas as necessary should be included in construction scope and budgets. 10.0 SHORING -SOLDIER PILE WALLS To achieve design daylight basement elevation, an excavation ranging in depth to 20 feet is currently anticipated for this project. Some form of temporary shoring will be required to support the temporary excavation where open cuts in conformance with recommended gradients are not feasible. This section of the report presents preliminary design considerations and criteria which should be considered in the design of the shoring for the excavation. With this information and other pertinent data, it should be the responsibility of the shoring subcontractor(s) to determine the appropriate design, construction methods, and procedures for installation of the shoring system. The most common method of shoring used in the area consists of a conventional soldier pile/waler shoring system utilizing steel soldier piles, sometimes in conjunction with an internally braced or tieback system. Soldier piles, which are wide-flange beams, are placed in pre-drilled holes which extend beyond the bottom of the excavation. The portion of each soldier pile extending below the bottom of the excavation is grouted in place with sufficient- strength concrete to transmit the vertical loads of the soldier beams to the soil below the excavation level. The upper portion of the soldier pile is then backfilled with a relatively weak grout so that it may be removed for placement of lagging. We recommend that lagging be backfilled with sand slurry pumped into place behind shoring walls to minimize the potential for movement of the cut soil. 10.1 Shoring Wall Retained Earth Pressures For cantilever walls, we recommend that the shoring system be designed to withstand lateral soil pressures based on "active" conditions. This design pressure, based on a level backfill, is in the form of an equivalent fluid equal to 35 pounds per cubic foot (pcf) triangular distribution acting over the pile spacing above the excavation level. Below the level of excavation, the 35 pcf may be considered to act only over the diameter of the grouted soldier pile section. Any applicable surcharges from adjacent structures, stockpiled materials, construction equipment, or sloping ground must be added to the above values. Where supporting a backslope of 1.5H:IV, an equivalent fluid equal to 60 pcf triangular distribution may be used. Again, February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

Any settlement-sensitive structures should be set back a minimum horizontal distance equal to the shoring wall height so that wall deflections/soil movement do not impact adjacent foundations. A combination of temporary l.SH:IV slopes and shoring may be utilized to reduce the overall height of shoring. Once the shoring/slope configuration is developed, AESI should be consulted to review the design parameters, as necessary. 10.2 Shoring Wall Passive Earth Pressure The soldier piles must be located a sufficient depth below the base of the excavation to provide adequate lateral resistance to horizontal loads. The lateral resistance may be computed on the basis of passive pressure in the form of an equivalent fluid equal to 300 pcf. The upper 2 feet of passive soil resistance should be ignored due to disturbance. This pressure may be considered to be acting against twice the diameter of the grouted soldier pile section. Piles should extend at least 10 feet below the excavation level. 10.3 Shoring Inspections Shoring installation should be observed by a representative of AESI to verify that subsurface conditions are as anticipated and that the shoring elements are installed in conformance with the shoring plan. Inspections should include pile installation, excavation and lagging placement, lagging backfill, and drainage. Survey monitoring of the piling and adjacent structures may also be required. 10.4 Tiebacks Tieback anchors may be used to aid in resisting lateral loading on the shoring system. A tieback system consists of drilling behind the soldier pile wall at an angle to the horizontal and installing rods or cables with a grout anchor. The anchor loads are transmitted to the surrounding soil by side friction or adhesion with the soil If requested, recommendations for design and testing of tieback anchors can be provided. 1l.0 STRUCTURAL FILL Structural fill will be necessary for wall backfill, utility backfill, and beneath hardscape. All references to structural fill in this report refer to subgrade preparation, fill type, placement, February 8, 2005 ASSOCIATED EARTH SCIENCES, INC. MThs -KE04752A2 -Projecfsl2004752lKE1WP Page 18 I I I I I I I I I I I I I I I I I I I Proposed Classroom/Maintenance Building (Building N) Renton Technical Col/ege Renton, Washington Subswface Exploration, Geologic Hazards, and Preliminary Geotechnical Engineering Repon Design Recommendations and compaction of materials as discussed in this section. If a percentage of compaction is specified under another section of this report, the value given in that section should be used. If fill is to be placed on slopes steeper than 5H: 1 V, the base of the fill should be tied to firm, stable subsoil by appropriate keying and benching which would be established in the field to suit the particular soil conditions at the time of grading. The keyway will act to embed the toe of the new fill into the hillside. Generally, the keyway for hillside fills should be at least 4 feet wide and cut into medium dense sand or stiff silt. Level benches would then be cut horizontally across the hill, following the contours of the slope. No specific width is required for the benches, although they are usually at least 4 feet wide. All fills proposed over a slope should be reviewed by our office prior to construction. After stripping, planned excavation, and any required overexcavation have been performed to the satisfaction of the geotechnical engineer/engineering geologist, the exposed ground should be recompacted to 90 percent of the modified Proctor maximum density using ASTM:D 1557 as the standard. If the subgrade contains too much moisture, adequate recompaction may be difficult or impossible to obtain and should probably not be attempted. In lieu of recompaction, the area to receive fill should be blanketed with washed rock or quarry spalls to act as a capillary break between the new fill and the wet subgrade. Where the exposed ground remains soft and further overexcavation is impractical, placement of an engineering stabilization fabric may be necessary to prevent contamination of the free-draining layer by silt migration from below. After recompaction of the exposed ground is tested and approved, or a free-draining rock course is laid, structural fill may be placed to attain desired grades. Structural fill is defined as non-organic soil, acceptable to the geotechnical engineer, placed in maximum 8-inch loose lifts with each lift being compacted to 95 percent of the modified Proctor maximum density using ASTM:D 1557 as the standard. The top of the compacted fill should extend horizontally outward· a minimum distance of 3 feet beyond the location of footings or pavement edges before sloping down at an angle of 2H: 1 V . The contractor should note that any proposed fill soils must be evaluated by AESI prior to their use in fills. This would require that we have a sample of the material 72 hours in advance to perform a Proctor test and determine its field compaction standard. Soils in which the amount of fine-grained material (smaller than the No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) should be considered moisture-sensitive. Use of moisture-sensitive soil in structural fills should be limited to favorable dry weather conditions. The on-site soils generally contained significant amounts of silt and are considered moisture-sensitive. In addition, construction equipment traversing the site when the soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained, a select import material consisting of a clean, free-draining gravel and/or sand should be used. Free-draining fill consists of non-organic soil with the February 8, 2005 MT/ts -KE04752A2 -ProjeclsI2004752\KE1WP ASSOClAJED EARTH SCIENCES, INC Page 19 I I I • I • I , I I I I I I I .'

An AESI representative should inspect the stripped subgrade and be present during placement of structural fill to observe the work and perform a representative number of in-place density tests. In this way, the adequacy of the earthwork may be evaluated as filling progresses and any problem areas may be corrected at that time. It is important to understand that taking random compaction tests on a part-time basis will not assure uniformity or acceptable performance of a fill. As such, we are available to aid the owner in developing a suitable monitoring and testing frequency. 12.0 FOUNDATIONS Spread ~ootings may be used for building support when founded directly on suitable advance outwash soil or on structural fill placed as previously discussed. Footings founded on suitable advance outwash sand or on structural fill above the advance outwash sand may be designed for an allowable foundation soil bearing pressure of 3,000 pounds per square foot (psI) including both dead and live loads. An increase of one-third may be used for short-term wind or seismic loading. All foundations must penetrate to the prescribed bearing stratum and no foundations should be constructed in or above loose, organic, or existing fill soils. In addition, all footings must have a minimum width of 18 inches. Perimeter footings should be buried at least 18 inches below lowest adjacent grade for frost protection; interior footings require only 12 inches burial. Considering the granular nature of the site soils, settlements are expected to be small and occur rapidly during the initial application of dead load. Anticipated settlement of footings founded as described above should be on the order of :y., inch with differential movement about half of that total. However, disturbed soil not removed from footing excavations prior to footing placement could result in increased settlements. Installation of settlement-sensitive surfaces should be delayed as long as practical. All footing areas should be inspected by AESI prior to placing concrete to veri~ that the design bearing capacity of the soils has been attained and that construction conforms to the recommendations contained in this report. The City of Renton may require such inspections. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. It should be noted that the area bounded by lines extending downward at IH:IV from any footing must not intersect another footing or intersect a filled area that has not been compacted to at least 95 percent of ASTM:D 1557. In addition, a 1.5H:IV line extending down from any footing must not daylight because sloughing or raveling may eventually undermine the footing. Thus, footings should not be placed near the edge of steps or cuts in the bearing soils. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

I I I I Proposed Classroom/Maintenance Building (Building N) Renton Technical College Renton, Washington 13.0 LATERAL WALL PRESSURES SubsUlface Exploration, Geologic Hazards, and Preliminary Geotechnical Engineering Report Design Recommendations All backfill behind walls or around foundation units should be placed as per our recommendations for structural fill and as described in this section of the report. Horizontally backfilled walls which are free to yield laterally at least 0.1 percent of their height may be designed using an equivalent fluid equal to 35 pcf. Fully restrained, horizontally backfilled rigid walls which cannot yield should be designed for an equivalent fluid of 55 pcf. Where driveway or parking areas are adjacent to walls, a surcharge equivalent to 2 feet of soil should be added to the wall height in determining lateral design forces. The lateral pressures presented above are based on the conditions of a uniform, level backfill consisting of free-draining soil compacted to 90 percent of ASTM:D 1557. A higher degree of compaction is not recommended as this will increase the pressure acting on the wall. A lower compaction may result in settlement of any slab-on-grade or other structures above the walls. Thus, the compaction level is critical and must be tested by our firm during placement. Surcharges from adjacent footings, heavy construction equipment, or sloping ground must be added to the above values. Footing drains should be provided for all retaining walls as discussed under the section on Drainage Considerations. It is imperative that proper drainage be provided so that hydrostatic pressures do not develop against the walls. This would involve installation of a minimum I-foot-wide blanket drain to within 1 foot of the top of the wall using imported, washed gravel against the walls. Less permeable on-site soil may be used as a cap over the gravel. Filter fabric (Mirafi 140N, or equivalent) should be placed over the gravel drain prior to soil cap placement to reduce the potential for migration of fines. 13.1 Passive Resistance and Friction Factors Retaining wall footings/keyways cast directly against undisturbed, dense outwash sediments in a trench may be designed for passive resistance against lateral translation using an equivalent fluid equal to 300 pcf. The passive equivalent fluid pressure diagram begins at the top of the footing; however, total lateral resistance should be summed only over the depth of the actual key (truncated triangular diagram). These values apply only to footings/keyways where concrete is placed directly against the trench sidewalls without the use of forms. 'If footings are placed on suitable advance outwash sediments and then backfilled, the top of the compacted backfill must be horizontal and extend outward from the footing for a minimum lateral distance equal to three times the height of the backfill before tapering down to grade. With backfill placed as discussed, footings may be designed for passive resistance against lateral translation using an equivalent fluid equal to 250 pcf and the truncated pressure diagram discussed above. Passive resistance values include a factor of safety equal to 3 in order to reduce the amount of movement necessary to generate passive resistance. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.

This value includes a safety factor of at least 1.5. 14.0 FLOOR SUPPORT The slab-on-grade floor may be founded on structural fill or unweathered outwash sediments. The floor should be cast atop a minimum of 4 inches of washed pea gravel to act as a capillary break. It should also be protected from dampness by a minimum lO-mil-thick vapor retarder membrane. 15.0 DRAINAGE CONSIDERATIONS All retaining and perimeter footing walls should be provided with a drain at the footing elevation. Drains should consist of minimum 6-inch-diameter, rigid, perforated, polyvinyl chloride (PVC) pipe surrounded by washed pea gravel. The level of the perforations in the pipe should be at least 12 inches below the bottom of the floor slab and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. Footing drains should be provided with cleanouts to allow periodic future cleaning/maintenance. All retaining walls should be lined with a minimum 12-inch-thick washed gravel blanket to within 1 foot of the top of the wall and which ties into the footing drain. Less permeable on- site soil may be used as a cap over the gravel. Filter fabric should be placed over the gravel prior to soil cap placement to reduce the potential for migration of fines into the wall drain. Roof and surface runoff should not discharge into the footing drain system but should be handled by a separate, rigid, tightline drain. In planning, exterior grades adjacent to walls should be sloped downward away from the structure (minimum 2 percent slope) to achieve surface drainage. 16.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, site grading, structural plans, and construction methods have not been finalized and the recommendations contained herein are preliminary. We are available to provide additional geotechnical consultation as the project design develops and possibly changes from that upon which this report is based. We recommend that AESI perform a geotechnical review of the plans prior to final design completion. In this way, our earthwork and foundation recommendations may be properly interpreted and implemented in the design. February 8, 2005 ASSOCIATED EARTH SCIENCES, INC.
