The parking lot would be sited to the south of the existing 25,300 square foot Shuttle Express building which is located within the central portion of the site. The proposal would expand the existing parking area by 36 parking stalls for employee use. A new 14-foot wide curb cut is also proposed in order to allow egress from the expanded parking area to SW 16th St. In addition, the applicant is proposing to construct frontage improvements along SW 16th Street and is requesting a waiver for street improvements along Raymond Ave SW. The subject property is located at 800 SW 16th St. The project site totals 3.25 acres in area and is located within the Medium Industrial (1M) zone. There are no critical areas located on site. A Class 4 stream is located on the northern border of the property however the construction would not occur within 100 feet ofthe stream. While the parcel contains a 100-year floodplain it is not located within the project limits. The elevation of the lOO-year floodplain is approximately 16 feet while the elevation of the proposed parking lot is between 19 and 22 feet. The applicant is proposing the excavation of 937 cubic yards of soil and is proposing to bring in approximately 558 cubic yards of fill. The proposal exceeds the SEPA threshold of 500 cubic yards of grading. Currently, 20% of the site is covered with impervious surfaces. Approximately 58% of the project site would be covered with impervious surfaces following construction. The applicant is proposing the removal of two existing trees which are proposed to be mitigated with the planting of 27 trees. The proposed dates for construction would occur during November and December of 2013. No public comments were received. I PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation B. Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS with a 14·day Appeal Period.

Environmentallmpacts , & Economic Development vironmental Review Committee Report WAH-OOHlZ, ECF Page 3 of 6 The Proposol was circulated and reviewed by various City Departments ond 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 fallowing probable impacts: 1. Earth Impacts: The subject site is relatively flat with the steepest slope on site at approximately 10%. The applicant provided a Geotechnical Engineering Report prepared by National Geotechnical Associates, Inc., dated June 21, 2013 (Exhibit 4). The subsurface conditions within the site were explored in June of 2013 by excavating four test pits. Underlying 0.2 feet of topsoil and grass approximately 3.8-4.8 feet of medium dense to dense, brown-gray fine sand with silt was encountered and is considered fill. Underlying the fill is loose/soft, brown-gray silty sand with varying amounts of gravel and organics. Groundwater seepage was observed at approximately 11.0 and 7.5 feet below the ground surface. Excavation and fill would be needed for construction of the proposed parking lot, required landscaping berm, and drainage layout. The applicant is proposing approximately 937 cubic yards of cut and is proposing approximately 558 cubic yards of fill. Currently, approximately 20% of the project site is covered with impervious surfaces. About 58% of the project site would be covered with impervious surfaces following project construction. There are no significant impacts anticipated. Mitigation Measures: No additional mitigation is required. Nexus: Not applicable. 2. Air Impacts: It is not anticipated that the project would Significantly impact air quality. Any new impacts would be primarily from construction. Air impacts from construction would be temporary and would be limited in duration. The applicant has indicated that construction vehicle emission would be controlled through the use of factory-installed mufflers and spark arrestors, reducing the amount of noxious emissions and noise and helping to control airborne dispersal. Furthermore, the Temporary Erosion and Sediment Control Plan (TESCP) would further reduce airborne particulates related to dust by controlled watering ofthe grounds during construction. Mitigation Measures: No further mitigation recommended. Nexus: Not applicable. 3. Water a. Storm Water Impacts: The existing conveyance system captures sheet flow from the existing grass area. Stormwater from the developed site would infiltrate through the porous asphalt. Overflow for the permeable pavement facility would be a catch basin conveyance system designed to capture and convey all stormwater to the City's system in 5W 16th St. A preliminary drainage plan and drainage report has been submitted with the site plan application, prepared by Davido Consulting Group, Inc., dated August 2, 2013 (Exhibit 5). The report addresses ERCReport City of Renton Department of Camn SHUTTLE EXPRESS PARKING LOT Report of November 18, 2013 Y & Economic Development Ivironmental Review Committee Report WAH-OOHll, ECF Page 4 of 6 compliance with the 2009 King County Surface Water Manual and the 2009 City of Renton Amendments to the KC5WM, Chapters 1 and 2. The project proposes the use of permeable pavement for flow control. Permeable pavement can be used to comply with the flow control BMP requirement; and/or to reduce the size of the required flow control facility. However, permeable pavement is not included in the surface water design manual as a flow control facility. Therefore, if compliance with the 0.1 cfs exemption cannot be achieved; then a flow control facility in accordance with Chapter S of the manual would be required. Additional information regarding flow control can be provided and would be reviewed during the construction permit stage. Proposed pollution generating impervious surface (PGIS) will be greater than 5,000 square feet, therefore water quality treatment is required. The soils beneath the pavement are designed to provide water quality treatment. If the soils beneath the pavement do not comply with the criteria in the manual, then water quality treatment would be required prior to infiltration. Additional information regarding water quality can be provided and would be reviewed during the construction permit stage. Mitigation Measures: No additional mitigation is required. Nexus: Not applicable. 4. Vegetation Impacts: There is existing landscaping around the perimeter ofthe site. Vegetation at the site primarily comprises of lawn and of 10 trees. Approximately 17,000 square feet of lawn would be removed and replaced with the permeable pavement parking lot and concrete sidewalk. An additional 5,000 square feet of grass would be cleared and reseeded. One large European birch tree and another smaller evergreen tree are proposed for removal. A conceptual landscape plan was submitted with the project application (Exhibit 3). The planting plan includes new vegetation on the perimeter of the site and within the proposed parking area. The proposed landscaping plan includes a total of 27 new trees, shrubs, and groundcover in the amount of 2,855 square feet. The planting plan consists of: Autumn brilliance serviceberry, incense cedar, Autumn gold maidenhair, and scarlet oak trees. Shrubbery includes: arctic fire dogwood, Mount Vernon English laurel, pink drift at rose, thunderbird evergreen huckleberry, and David's viburnum. The applicant is also proposing a variety of groundcover. The proposed landscaping would be used to provide a transition between the parking area and the public right of way. The vegetation proposed would enhance screening of the new parking lot from the street and properties to the south. The landscaping softens the appearance of the entire development and generally enhances the appearance of the project. A final planting plan would be required to be provided to, and approved by the Current Planning Project Manager, prior to construction permit approval. Mitigation Measures: No additional mitigation is required. Nexus: Not applicable. 5. Transportation Impacts: The site has two public street frontages, SW 16'h St (Collector Arterial) and Raymond Ave SW. Access is currently provided from a single curb cut along 5W 16'h 5t and three curb cuts along Raymond Ave 5W. The applicant is proposing an additional exit only driveway onto 5W 16th St. ERCReport City of Renton Department of Comm SHUTTLE EXPRESS PARKING LOT Report of November 18, 2013 , & Economic Development 'vironmenta/ Review Committee Report WAH-OOH22, ECF Page 5 of6 Street improvements along SW 16th St include 0.5-foot wide curb, 8-foot wide landscaped planter, 5-foot wide sidewalk, and I-foot wide clear space behind the sidewalk. Right-of-way dedication is required in the amount that all required frontage improvements are within the public right of way and is to be determined during final engineering review. Street improvements along Raymond Avenue include 0.5-foot wide curb, 8-foot wide landscaped planter, 5-foot wide sidewalk, and I-foot wide clear space behind the sidewalk. The applicant has requested a waiver of frontage improvements along Raymond Ave SW. This request has been given preliminary approval by both Transportation Department and the Plan Review Division as Raymond Ave SW is a dead end street_ The proposed parking lot expansion project does not generate additional new trips. Therefore, traffic impact fees are not applicable for the proposal. Mitigation Measures: No additional mitigation is required. Nexus: Not applicable. D. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers. Where applicable, their comments have been incorporated into the text of this report and/or "Advisory Notes to Applicant." ,/ Copies of all Review Comments are contained in the Official File and may be attached to this report.

Community Services Review leslie Betlach Ph: 425-430-6619 email: LBetlach@rentonwa.gov May 29, 2014 Recommendations: 1. Recommend against using oak trees especially where they will overlap the right-of-way. Recommendations: I have completed a preliminary review for the above-referenced parking lot expansion proposal at BOO SW 16th Street. The following comments are based on the application submittal made to the City of Renton by the applicant. EXISTING CONDITIONS WATER: The site is located in the City of Renton water service area. SEWER: The site is located in the city of Renton sewer service area. STORM: There is storm drainage in Nile Avenue NE. STREET: Nile Avenue NE fronting the site is a residential street. CODE REQUIREMENTS Water 1. The proposed project does not have any water utility impacts. The proposed project elements and the frontage improvements should not impact the existing water lines. Sanitary Sewer 1. The proposed project does not have any sewer utility impacts. The proposed project elements and the frontage improvements should not impact the existing sewer lines. Stormwater 1. A drainage report prepared by Davido Consulting Group, Inc., was submitted for the proposed project. The drainage report follows the 2009 King County Surface Water Manual and City Amendments. Based on the City's flow control map, this site falls within the Peak Rate Flow Control Standard (Existing Conditions). The project is subject to full drainage review. The project proposes the use of permeable pavement for flow control. Permeable pavement can be used to comply with the flow control BMP requirement; and/or to reduce the size of the required flow control facility. But, permeable pavement is not included in chapter of the surface water design manual as a flow control facility. Therefore, if compliance with the 0.1 cfs exemption cannot be achieved; then a flow control facility in accordance with chapter 5 will be required. Additional information regarding flow control can be provided and will be reviewed during the construction permit stage. Proposed pollution generating impervious surface (PGIS) will be greater than 5,000 sf, therefore water quality treatment is required. If the soils beneath the permeable pavement comply with the criteria described in section 1.2.4H and 1.2.B of the Surface Water Design Manual for ground water protection, then the implementation of permeable pavement for parking will be allowed. The soils beneath the pavement will be providing the treatment. If the soils beneath the pavement do not comply with the criteria listed above, then water quality treatment is required prior to infiltration. Additional information regarding water quality can be provided and will be reviewed during the construction permit stage. Drainage plans and a final drainage report based on the City adopted 2009 Surface Water Design Manual Amendment and the 2009 King County Surface Water Drainage is required to be submitted with the Construction permit. The final drainage report must include information of all the core requirements and the special requirements, especially the requirements for flow control, water quality, and stormwater BMPs. 2. A geotechnical report and an addendum prepared by Nelson Geotechnical Associates, Inc., were submitted for the proposed project. The geotech report recommended the pervious pavement for the parking lot. For light traffic areas, a pervious pavement section consisting of 4 inches of pervious pavement underlain by a minimum of 6 inches of crushed was recommended. For heavy traffic areas, a section of 6 inches of pervious pavement underlain by a minimum of 12 inches of crushed rock was recommended. 3. The current surface water system development fee is $0.448 per square feet of new impervious surface with a minimum amount of 1 , 120.00. Page 1 of 2 Planning Review Technical Services Reviewer Comments Transportation 1. The proposed parking lot p .t proposes an additional exit only driveway onto S! ~th Street. The new driveway must have sufficient width and turnin. us to serve the movements of the largest vehicle t Ie the site. 2. The existing driveway on SW 16th Street must have a driveway approach type entrance. The existing driveway on SW 16th Street will function as an entrance only driveway. A sidewalk ramp is to be provided at the transition between the proposed sidewalk and the driveway. The proposed sidewalk must extend to the intersection of Raymond Ave SW and SW 16th Street. Sidewalk curb ramp (as per ADA requirement) is to be provided at the end of sidewalk at the intersection of Raymond Ave SW and SW 16th Street. Dedicate a radius edge at the property corner at the intersection of Raymond Ave SW and SW 16th Street to provide a rounded property corner. All portions of sidewalk must be within the public right of way. 3. SW 16th Street is a collector arterial. The City has corridor level plan that includes for the SW 16th Street frontage a 0.5' wide curb, 8 feet wide landscaped planter, 5 feet wide sidewalk, and 1 foot wide clear space behind the sidewalk. Right of way dedication must be provided so that all the required frontage improvements are within the public right of way. The street lights (that meet City standards) must be relocated to account for the frontage improvements that will be provided by the project. 4. As per code, the frontage requirements on Raymond Avenue include 0.5 feet wide curb, 8 feet wide landscaped planter, 5 feet wide sidewalk, and 1 foot wide clear space back of the sidewalk. However, the applicant has requested a waiver of frontage improvements on Raymond Avenue SW. This request has been given preliminary approval by both Transportation and Plan review since Raymond Ave SW is a dead end street. 5. Traffic Impact Fees -The proposed parking lot expansion project does not generate additional new trips. Therefore traffic impact fee is not applicable on this project. General Comments 1. All construction or service utility permits for drainage and street improvements will require separate plan submittals. All utility plans shall conform to the Renton Drafting Standards. Plans shall be prepared by a licensed Civil Engineer. 2. When utility plans are complete, please submit three (3) copies of the drawings, two (2) copies of the drainage report, permit application, an itemized cost of construction estimate, and application fee at the counter on the sixth floor.

We have previously prepared a geotechnical engineering letter for the project site titled "Geotechnical Engineering Evaluation -Shuttle Express Parking Lot and infiltration -Renton, Washington," dated June 21,2013. in this letter, we provided recommendations for the pervious pavement sections. Specifically, we recommended that the pervious pavement section for light traffic areas consist of a minimum of 6- inches of pervious pavement surfacing underlain by at least 12-inches of clean crushed rock. Since our letter was submitted, we have had conversations with the civil and structural engineers regarding the proposed pervious pavement sections for both light and heavy traffic areas of the proposed parking lot. These conversations resulted in updated pervious pavement sections of 4-inches of pervious pavement underlain by a minimum of 6-inches of clean crushed rock for the light traffic are~~1~liD .,..

We have been provided with Plan Sheets COl through COS titled "Shuttle Express -Renton Parking Lot," dated August 2, 2013, We have reviewed geotechnical aspects of the provided plans and found the plans to be in general accordance with our recent conversations and our previous geotechnical letter. In our opinion the updated pervious pavement sections for the light and heavy traffic areas should be feasible provided our recommendations in our previous letter and in this memo are followed during construction. We recommend that NGA be retained to provide monitoring and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether earthwork activities comply with contract plans and specifications. We trust this memorandum should satisfY your needs at this time. Please contact us if you have any questions orr-equire additional services.

The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. 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, Community & Economic Development Administrator, Public Works Administrator, Planning Director, Development Services Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available for purchase for $50.00 plus tax, from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov Project Proposal: The subject property is located at 800 SW 16th Street. The project site totals 3.25 acres in area and is located within the Medium Industrial (1M) zone. The pre-application packet indicates that the proposal is to expand the existing parking area by converting a 16,500 s.f. area of lawn to surface parking for employee use. A new curb cut would be added to allow exit onto SW 16th Street, and it appears that exiting from the new parking lot would be via and existing internal driveway that is accessed via SW 16th Street. In addition, the applicant intends to construct a new concrete sidewalk and curbs. Current Use: The property currently contains an existing 25,300 square foot building utilized by Shuttle Express, of which approximately 5,000 square feet is used for warehouse and storage. A large parking lot for vehicle storage/staging and a 1,000 gallon propane tank currently are located at the subject site. Zoning: The property is located within the Employment Area Valley (EAV) land use deSignation and the Medium Industrial (1M) zoning designation. Express Transportation Services are outright permitted uses within the 1M zone. h:\ced\planning\current planning\preapps\13-0000S0.rocale\pre13-0000S0 (im shuttle expresJt,IiC E IVE D lot expansion).doc SEP 30 7 013 CITY Or RH,110N PIJ->.J..j[\jii\iG DI'v'!SICY\j Shuttle Express Parking Lot, PRE13-0000S0 Page 2 of 14 January 24, 2013 Development Standards: The project would be subject to RMC 4-2-130A, "Development Standards for Industrial Zoning Designations" effective at the time of complete application (noted as "1M standards" herein). Minimum Lot Size. Width and Depth -There are no minimum requirements for lot width or depth within the 1M Zone, however, there is a minimum lot size requirement of 35,000 square feet which is not applicable to the proposal. Lot Coverage -There is no minimum lot coverage requirement within the 1M zone. Setbacks -Setbacks are the distance between the building and the property line or any private access easement. The required setbacks in the 1M zone are as follows: 15 feet for a front yard and side yard along a street; zero for the rear yard; zero for the interior side yards; and a 10-foot landscaped setback is required from the freeway. The proposal appears to comply with the required setback requirements. Landscaping -Except for critical areas, all portions ofthe development area not covered by structures, required parking, access, circulation or service areas, must be landscaped with native, drought-resistant vegetative cover. The development standards require that all pervious areas within the property boundaries be landscaped. The minimum on- site landscape width required along street frontages is 10 feet. Street trees are required either between the curb and the sidewalk or where there is insufficient right-of-way space street trees are required in the front yard subject to approval of the Department of Community and Economic Development Administrator. When an Industrial Zoned Lot or Use is Abutting a Residential or CommerCial Zone: A fifteen-foot (15') wide partially sight-obscuring landscaped visual barrier, or ten-foot (10') wide fully sight-obscuring landscaped visual barrier, is required along the common property line. The subject site abuts a Commercial Office (CO) zone to the west and would be required to provide landscaping along the west property line. A minimum of ten feet (10') landscaped strip is required between the property line along public rights-of-way and the fence. The landscaping shall be of size and variety so as to provide an eighty percent (80%) opaque screen. It should be noted thot the subject project received 0 Site Plan approval in 1998, City file number LUA98-156. Pursuant to the past approval Z% of the site was required to be maintained as natural landscaping suitable for wildlife habitat. Information shol/ be provided at of/icia/site plan permit submittal verifying compliance with LUA98-156 approval requirements. Please refer to landscape regulations (RMC 4-4-070) for additional general and specific landscape requirements (enclosed). A conceptuol landscope plan and landscape analysis meeting the requirements in RMC 4-8-1Z0D.1Z, shall be submitted at the time of application for Site Plan Review. Landscaping standards from Renton Municipal Code are attached as an exhibit at the conclusion of this memo. Substantial landscaping would be required, and a minimum Shuttle Express Parking lot, PRE13-0000S0 Page 3 of 14 January 24, 2013 buffer area between the back of sidewalk and the parking lot. Berming is encouraged to help screen and reduce headlight sweep impacts. Fences -The applicant shall provide details of any fences proposed as part of this project, the location must be deSignated on the landscape plan. A fence detail should also be included on the plan as well. Parking -Express Transportation Services are not specifically identified within the development code and parking standards. Therefore, staff would require some additional information in order to calculate parking demand. We would apply parking requirements based on the existing office use; therefore, please provide the area of net office space. General office requires a minimum of 2.0 parking spaces per 1,000 s.f. of net floor area and a maximum of 4.5 parking spaces per 1,000 s.f. of net floor area. In addition, we would need to know how much area is used for fleet parking. The proposed parking lot may require a modification from parking requirements if the parking exceeds or is less than the required parking, or if bicycle parking requirements cannot be met (see below). Modifications are subject to a $100 fee (plus 3% technology fee). In addition, RMC 4-4-080.F11 requires that bicycle parking be provided eqUivalent to 10% of the number of required parking spaces. Note: It appears that there is the ability to provide additional parking within the existing improved area by reconfiguring and restriping. Staff discussed with the applicant that the City's position is to ollow only an expansion oJ the existing parking toward SW lff1' Street (approximately one-halJ the distance between the existing building and the property line, plus a new curb cut to sw uP Street. The curb cut will also Jacilitate improved traffic flow if the parking spaces are reconfigured. Access -Driveway widths are limited by the driveway standards, in RMC 4-40801. The location of ingress and egress driveways shall be subject to approval of the Community and Economic Development Department under curb cut permit procedures. There shall be a minimum oHorty feet (40') between dr'lveway curb returns where there is more than one driveway on property under unified ownership or control and used as one premises. Driveways shall not exceed forty percent (40%) of the street frontage. The width of any driveway shall not exceed fifty feet (50'). There shall not be more than two (2) driveways for each three hundred thirty feet (330') of street frontage on property under unified ownership or control. Staff was unable to verify compliance with driveway spacing standards as the site plan was not presented in a usable scale. Street Improvements -The project would require the construction of street improvements, if the proposed work is valued at $50,000 or more. The applicant shows that sidewalks would be constructed. RMC4-6-060F requires an 8-foot wide sidewalk for an Industrial Collector street, and an 8-foot wide planting street abutting the street. If the street is classified as Industrial Access, then the sidewalk can be 6-foot wide, and the planning strip is required to be 8-feet wide. Shuttle Express Parking Lot, PRE13-000050 Page 4 of 14 January 24, 2013 Critical Areas The City of Renton's Critical Areas maps indicate the presence of Seismic hazards and lOO-year flood plain on the subject site. The seismic hazard is related to potential liquefaction of soils during an earthquake event. A geotechnical analysis may be requ"'red for the site. If required, the analysis needs to assess soil conditions and detail construction measures to assure bUilding stability. The subject site contains a Flood Hazard Area; pursuant to the FEMA Flood Insurance Rate Maps (FIRM) the subject site contains a Special Flood Zone which is classified as a IOO-year flood plain. Based on the project proposal no development is proposed within the flood plain. However, if development is proposed in the flood plain, the applicant should address the issues raised in the Final Biological Opinion And Magnuson- Stevens Fishery Conservation and Management Act Essential Fish Habitat Consultation and propose mitigation for any anticipated impacts as it would relate to the referenced publication, in the SEPA review for the project. The SEPA checklist should be provided to the National Marine Fisheries Service (NMFS) and the Federal Emergency Management Agency (FEMA) for their review and comment. Environmental Review The proposed project would be subject to Washington State Environmental Policy Act (SEPA) review if the proposal adds or restripes more than 20 parking stalls. Therefore, an environmental checklist is a submittal requirement. An environmental determination will be made by the Renton Environmental Review Committee. This determination is subject to appeal by either the project proponent, by a citizen of the community, or another entity having standing for an appeal. Permit Requirements The proposal would require Administrative Site Plan and Environmental (SEPA) Review. The purpose of the Site Plan process is the detailed arrangement of project elements so as to be compatible with the physical characteristics of a site and with the surrounding area. An additional purpose of Site Plan is to ensure quality development consistent with City goals and policies. General review criteria include the following: Q.

ENV[RONMENTAL CHECKLIST Purpose of checklist: The State Environmental Policy Act (SEPA). chapter 43.21C RCW. requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. 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 identity impacts from your proposal (and to reduce or avoid impacts from the proposal, ifit can be done) and to help the agency decide whether an EIS is required. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write I'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 infurmation 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 ifthere may be significant adverse impact. Use of checklist for nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDrTlON, complete the SUPPLEMENTAL SHEET FOR NON PROJECT ACTIONS (part D). For non project actions, the references in the checklist to the words "project," "applicant," and IIproperty or site" should be read as "proposal, II IIproposer," and "affected geographic area," respectively.

If so, describe the type of waste and anticipated volume of discharge. The project does not involve any discharge of waste materials to surface waters. b. Ground: t) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. EVALUATION FOR AGENCY USE ONLY No groundwater will be withdrawn. The proposed porous asphalt parking lot has been designed to infiltrate all runoff from the site_ Therefore, stann water will be discharged to ground water through infiltration, but not before the water flows through a soils treatment layer. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals ... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material will be discharged into the ground from septic tanks or other sources. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The source of runoff will be stormwater. Stonnwater will be infiltrated through the proposed permeable pavement facility which will have a 6" rock stormwater storage layer. The permeable pavement facility has been sized using the King County Runoff Time Series (KCRTS) Hydrologic Simulation Model to handle all runoff from the proposed parking lot from a IOO·year storm. [n the rare case of an overflow. or if the porous asphalt gets clogged and cannot infiltrate storm water, a catch basin conveyance system has been designed_ Four catch basins will collect any water that cannot infiltrate through the permeable pavement and will convey storm water to the City of Renton's storm system via an existing catch basin in SW 16 th Street. 2) Could waste materials enter ground or surface waters? If so, generally describe. Waste materials will not enter surface waters as there are no surface waters within the immediate vicinity of the project site. Waste materials could enter the ground water by infiltrating through the permeable pavement facility_ However. the permeable pavement facility includes a 12" soils treatment layer that will remove most pollutants from the stormwater before it reaches the ground water. It is also unlikely that waste materials will be present on the site as it is primarily employee parking and not an industrial parking site for machinery or materials_ 5 TO BE COMPLETED BY APPLICANT d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: EVALUATION FOR AGENCY USE ONLY Runoff water impacts will be reduced significantly through the full-infiltration permeable pavement facility. Ground water impacts will be reduced through the 12" soils treatment layer beneath the permeable pavement facility that will remove most pollutants before the water reaches the ground water. 4.

PROJECT NARRATIVE 1.1 Project name, size and location of site The name of the proposed project is the Shuttle Express Parking Lot. The project site is approximately 44,000 SF and is a small portion large parcel that totals 141,425 SF. The site is located at 800 SW 16th Street in Renton, Washington. 1.2 Land use permits required for proposed project Land use permits required for this project include Site Plan Review and SEPA Review (Environmental Checklist). 1.3 Zoning designation of the site and adjacent properties The project is located within the Medium Industrial (1M) zoning designation. The adjacent property to the west is located in Commercial Zone. Bordering the project to the north is Interstate 405, to the east is Raymond Avenue SW, and the south is SW 16th Street. 1.4 Current use of the site and any existing improvements The property contains an existing 25,300 SF building for the Shuttle Express business, of which approximately 5,000 SF is used for warehouse and storage. To the north, east, and west of the building is large parking areas for the Shuttle Express buses, employees, and customers. This project proposes to add an approximately 15,000 SF parking lot to the south of the existing building. 1.5 Special site features (i.e. wetlands, water bodies, steep slopes) There are no wetlands or steep slopes located on the project site. A small creek borders the site to the north. However, all development from the proposed project will be occurring in the south portion of the site and will have no effect on the stream. 1.6 Statement addressing soil type and drainage conditions Nelson Geotechnical Associates, Inc. (NGA) completed a geotechnical investigation of the onsite soils and completed a summary of the results of the investigation on June 21, 2013. NGA dug four test pits and found that topsoil and grass was underlain by approximately 3.8 to 4.8 feet of medium dense to dense, brown gray fine sand with silt, trace gravel and varying amounts of organics which is thought to be undocumented fill. Below the fill layer is a loose/soft, iron-oxide stained, native alluvium soils layer. NGA also conducted two infiltration tests of the onsite soils. They recommended using an infiltration rate of 0.5 inches per hour for storm water modeling. Lastly, NGA concluded that the site is not suited for infiltration trenches due to indications of shallow groundwater, but that the use of pervious pavement is feasible. 1.7 Proposed use ofthe property and scope of the proposed development The proposed use of the property will continue to be for the Shuttle Express business. The proposed development will include an approximately 15,000 SF porous asphalt parking lot to the south of the existing building. The project will also include drainage for the improvem~ CJ V grading, and landscaping. Frontage improvements to SW 16th Street, which includes a lhlill1;~1!-ED strip and 6-foot wide sidewalk, are included in this project as well. SEP 302013 Davido C onsultmg Group, Inc.

Specifically, our scope of services includes the following: 1. Review existing soils and geologic maps of the area. 2. Explore the site subsurface soil and groundwater conditions with backhoe-excavated test pits. Backhoe to be subcontracted by NGA. 3. Perform on-site infiltration testing. 4. Perform laboratory analysis on representative soil samples, as needed. 5. Provide recommendations for storrnwater infiltration per 2009 King County Surface Water Design Manual and City of Renton Ammendments. 6. Provide recommendations for pavement subgrade preparation and pavement sections. 7. Provide recommendations for site drainage and erosion control. 8. Provide recommendations for infiltration system installation. 9. Document the results of our explorations, flndings, conclusions, and recommendations in a written geotechnical engineering report. SITE CONDITIONS Surface Conditions The site is a relatively level, rectangular shaped lot covering approximately 3.25 acres. The site is bounded to the north by Interstate 405, to the east and west by commercial properties and to the south by SW 16'h Street. An existing multi-level office building is located within the central portion of the site with asphalt parking and driveway areas along the north, east and west sides of the building. The proposed parking lot expansion is to be located within a grass lawn area to the south of the office building along SW 16'" Street. We did not observe surface water on the site during our visit on June 3, 2013. Subsurface Conditions Geology: The site is mapped on the Geologic Map of the Renton Quadrangle. King County. Washington, by D.R. Mullineaux (1965). The site is mapped as Alluvium (Qaw). The alluvium deposits are described as sand silt and clay deposits. Qur explorations generally encountered undocumented fill soils underlain by silty sand to silt deposits generally consistent with the description of alluvium at depth. NELSON GEOTECHNICAL ASSOCIATES, INC. , Stonnwater Infiltration Letter Shuttle Express Parking Lot and Infiltration Renton, Washington June 21, 2013 NGA File No. 875613 Page 3 Explorations: The subsurface conditions within the site were explored on June 3, 2013 by excavating four test pits with a backhoe. The approximate locations of our explorations are shown on the Schematic Site Plan in Figure 2, A geologist from Nelson Geotechnical Associates, Inc, (NGA) was present during the explorations; collected samples of the soils encountered, and maintained logs of the explorations, The soils were visually classified in general accordance with the Unified Soil Classification System, presented as Figure 3, The logs of the explorations are presented as Figure 4, Each of the test pits exposed a surficial layer of topsoil and grass to a depth ofO,2 feet below the existing ground surface, Underlying the topsoil and grass in all of our test pits we encountered approximately 3.8 to 4,8 feet of medium dense to dense, brown gray fme sand with silt, trace gravel and varying amounts of organics which we interpreted as undocumented fill. Below the fill in all of our test pits, we encountered loose/soft, iron-oxide stained, brown gray to gray silty sand and sandy silt with varying amounts of gravel and organics underlain by soft to very soft, blue gray to gray sand, silt with abundant orgaincs that we interpreted as native alluvium soils mapped for the area, All of our test pits were terminated within the native alluvium soils at depths in the range of 8,5 to 12,0 feet below the existing ground surface. Hydrologic Conditions Groundwater seepage was observed at approximately 11.0 and 7.5 feet below the ground surface in Test Pit I and 3, respectively. In addition, zones of iron oxide staining and saturated soil conditions were encountered within all of the test pits between approximately 4,0 to 12,0 feet. In our opinion, the groundwater seepage, iron oxide staining and saturated soil conditions are indicative of the high groundwater table associated with the nearby river. SEISMIC HAZARD The site is shown on the Liquefaction Susceptibility ofthe Renton Quadrangle, Washington by Stephen p, Palmer, Henry W, Schasse, Dave K. Norman, et. al. (WSDNR, 1994) to have a high liquefaction potential. Liquefaction is the temporary loss of the shear strength of a loose soil deposit (usually submerged clean fine to medium sand) due to a rise in pore water pressures during a seismic event. When subjected to prolonged cyclic dynamic loads, the pore pressures within a saturated sand deposit increase, approaching the total overburden pressure. At that time, a "quick" condition develops causing the soil to temporarily lose its load carrying ability. Depending on the depth to the liquefiable soils and actual loads, surface settlements can result from liquefaction, NELSON GEOTECHNICAL ASSOCIATES, INC. Storrnwater Infiltration Letter Shuttle Express Parking Lot and Infiltration Renton, Washington June 21, 2013 NGA File No. 875613 Page 4 The majority of the site soils at depth within our explorations consisted oflow permeability silts and silty sand. We did not encounter saturated clean sand layers within our explorations. However, clean sand layers under groundwater table may exist at depth underlying the site. Based on the soils encountered within our explorations, we expect the liquefaction potential for the upper site soils to be low. However, there may be some potential of liquefaction of soil layers at depth below the site, but in our opinion we would anticipate the impact to the site would be minimal. ON-SITE INFILTRATION TESTING We conducted two on-site infiltration tests in the proposed parking lot area. The infiltration tests were performed within the upper granular fill and underlying native silty sand soils within the parking lot area. For the infiltration tests, we installed a six-inch diameter vertical tube into the native silty sand soils in Test Pit 2 at a depth of 5.0 feet below the adjacent ground surface and in the upper granular fill soils in Test Pit 4 at a depth of approximately 4.0 feet below the adjacent ground surface. Approximately two inches of pea gravel was placed over the soil in the bottom of the tube to limit disturbance of the soil when water was added to the apparatus. We filled the tube with water and allowed the water to pre-soak the underlying soils before the actual infiltration testing. After the presoak, we conducted timed infiltration tests. The infiltration test results are shown below in Table 1. We have not applied a factor of safety to the in-place infiltration test results shown in the table. Table 1.

In our opinion, based on the soil and groundwater conditions encountered in our test pits, the site conditions do not meet these minimum requirements for infiltration. NELSON GEOTECHNICAL ASSOCIATES, INC. Stormwater Iniiltration Letter Shuttle Express Parking Lot and Infiltration Renton, \Vashington June 21, 2013 NGA FIle No. 875613 Page 5 It is our opinion that the site subsurface soils are poorly suited for traditional stormwater infiltration trenches. The subsurface soils generally have a high silt content and indications of shallow groundwater within these soils were observed in all of Our explorations. It is also our opinion that the use of pervious pavement surfacing to allow runoff from the parking lot to infiltrate into the granular fill layer found within the site is feasible. Specific recommendations for pervious pavement design have been provided in the Pervious Pavemeut Design subsection of this letter. Pervious pavement requires on-going maintenance in order to prolong the life span of the pavement. Specific recommendations for maximizing the life span of the proposed pervious pavement are included in the Pavement Maintenance subsection of this letter. We should emphasize that on-going maintenance of the pavement is essential for the long-term success of this approach. All recommendations for pavement subgrade preparation and maintenance as presented in this letter should be followed for the parking lot. We are providing a preliminary pavement design; however, this design should be verified by the civil engineer, bascd on actual anticipated loads and expected performance and life span of the pavement, and should also be checked against the recommendations of the pavement supplier. Pervious Pavement Design We recommend that the pervious pavement section for the parking lot be a minimum of 6 inches thick and underlain by a minimum of 12 inches of clean crushed rock. This pavement section is preliminary and assumes only light traffic would be imposed on the pavement. Permanent design should be the subject to specific analysis prepared by the civil or traffic engineer and approval by the supplier. Based on the low permeability soils encountered throughout the site at depth, we recommend that the pervious pavement section be underlain by a minimum of 12 inches of 3/4-inch clean crushed gravel with a minimum void ratio of 15 to 20 percent. The gravel should contain no more than 3 percent fines by weight in order to readily infiltrate into the underlying soils. The gravel layer should help facilitate infiltration, but will also aid in providing storage for infiltrating water. This layer should only be lightly compacted. The subgrade below the crushed rock should be stripped of grass and topsoil material to expose the granular fill soils prior to placing the crushed rock. These soils should generally be encountered approximately one foot below the existing ground surface. The subgrade below the gravel layer should be scarified to a depth of six inches and graded level. The exposed subgrade should not be heavily compacted or contaminated with silt, as these conditions may reduce the infiltration capability of NELSON GEOTECHNICAL ASSOCIA TES, INC. Stormwater Infiltration Letter Shuttle Express Parking Lot and Infiltration Renton, Washington June 21,2013 NGA File No. 875613 Page 6 this material. Also, construction traffic on the exposed sub grade should be avoided. We should be retained to observe sub grade preparation prior to placing the crushed rock layer. Based on our observations and on-site infiltration testing along with the varying nature of the underlying soils throughout the site, we recommend that a design infiltration rate of 0.5 inches per hour be used for the granular fill material encountered near the ground surface. Additional recommendations and information regarding pervious pavements are discussed on Pages 97 through III in the Low Impact Design Technical Guidance Manual for Puget Sound, (Puget Sound Action Team & Washington State University, May 2005). The existing underlying fill and crushed rock surface should be proof-rolled with a heavy, rubber-tired piece of equipment, to identify soft or yielding areas that require repair, however, the clean gravel layer should only be lightly compacted. We should be retained to observe the proof-rolling, as well as the placement of the gravel layer, prior to placement of pervious pavement. After installation, pervious pavements should be thoroughly swept and pressure-washed periodically to minimize siltation potential as discussed in the following section. Pavement Maintenance Typical methods for maintaining paved parking areas should be applied to pervious pavement. These methods include power sweeping, blowing, vacuuming, and high-pressure washing. Keeping debris from accumulating on top of and within the pervious pavement is important to maintaining the design infiltration capacity of the system. Should the pavement become partially clogged with debris, permeability could possibly be re-established with the use of vacuuming or pressure washing. Stormwater from sources outside the pavement should never be directed onto the pervious pavement or subgrade. Fines and organic material from off-site sources could potentially promote clogging of the pavement section. Following the recommendations provided in this letter should help reduce the migration of silt and debris into the pavement section.
