"Chip" Vincent, Administrator Renton Firestone on 1081h/ LUA16-000782, ECF, CU-A ,SA-A, MOD Dear Mr. Randles: Thank you for submitting the additional materials requested in the November 9, 2016 letter from the City. Your project has been taken off hold and the City will continue review of the Renton Firestone project. The Conditional Use Permit and Site Plan Review application has been rescheduled for Environmental Review Committee review on February 27, 2017. If you have any questions, please contact me at (425) 430-6593 or mherrera@rentonwa.gov Matthew Herrera, AICP Senior Planner cc: Real Property Investors/ Owner(s) Luke Randles, Pacland / Applicant Jerry Sammons, John and Karen Snarski, Mark Sandler, Zoe Mattson/ Party(ies) of Record 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov Denis Law Mayor November 9, 2016 Community & Economic Development C. E. "Chip" Vincent, Administrator Luke Randles PACLAND 1505 Westlake Ave N, Ste 305 Seattle, WA 98117 SUBJECT: "On Hold" Notice Renton Firestone on 108th, LUA16-000782, ECF, CU-A, SA-A, MOD (4) Dear Mr. Randles: The Planning Division of the City of Renton accepted the above master application for review on October 17, 2016. During our review, staff has determined that additional information is necessary in order to proceed further. The following information will need to be submitted before February 7, 2016 so that we may continue the review of the above subject application: 1. Stormwater -The provided Technical Information Report (TIR) is incomplete and includes information for the CarMax project. A completed TIR and associated drainage plans (if revisions are needed) must be resubmitted. 2. Setbacks -The front yard for the subject property is along the 108th Ave SE frontage. After right-of-way dedication along 108th Ave SE, the building is shown on the site plan to be setback between 15-feet on the southwest corner of the building and taper to an approximate 13.6 feet setback at the northwest corner resulting in an encroachment into the 15-foot setback for portions of the building (RMC 4-4-120A). Revised site, landscape, and civil plans must be resubmitted that show compliance with the 15-foot minimum setback. 3. Landscaping -The required street frontage landscaping between the building and the sidewalk is shown within the dedicated ROW. Required street frontage landscaping (trees, shrubs, and groundcover) must be provided onsite and not in the area of dedicated ROW (RMC 4-4-070F.l}. The remaining undeveloped dedicated ROW between the subject property and the sidewalk shall be landscaped with shrubs and groundcover (RMC 4-4- 070F.2). The required perimeter landscaping screen between the surface parking lot and dedicated ROW line along 108th Ave SE is approximately 8.5-feet and does not comply with the 10- foot width minimum as shrub planting is located within the dedicated ROW. The parking area must be setback 10-feet from dedicated ROW and contain perimeter lot landscaping within the 10-feet that meet the planting requirements of RMC 4-4-070H.4. 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov Internal parking lot landscaping is separated by more than SO-feet and does not meet RMC 4-4-070 4. Building Design -The following design comments reflect the Urban Design Regulations for the subject property's Design District 'D' overlay, Conditional Use Permit decision criteria, and comments provided at the preapplication meeting. Revised elevations reflecting these . comments must be resubmitted. a) Roof profile -The building elevations provide limited transition treatments with regard to the neighboring R-8 zone and single-family residential uses. As mentioned at the preapplication meeting, transition to the neighboring zone is an important aspect of review for the design regulations and CUP criteria. Staff identified the use of pitched roof instead flat roof profiles during the preapplication meeting to meet this requirement. (RMC 4-3-lOOE.1.'Transition to Surrounding Development'). b) Transparency -There is insufficient transparency on facades visible to the public. At least SO-percent transparent windows and/or doors for the fa~ade between 4-feet and 8-feet above ground (RMC 4-4-lOOES 'Ground Level Details'). More glazing is needed and a calculation provided to verify compliance must be provided on the revised elevation sheet(s). c) Building materials -The abundance of CMU and EIFS exterior cladding does not provide an attractive and high quality material variation that is warranted for a commercial development in close proximity to a residential zone (RMC 4-3-lOOE.S Building Materials). The facades should maintain a prominent brick exterior that provides banding and patterns with smaller sections of EIFS treatments to provide material variation. CMU exteriors should be removed altogether with the exception of banding. d) Modulation -The building provides no apparent modulations to break up the bulk of the north, west, and south facades. Modulations are needed meeting the requirements of RMC 4-4-lOOE.S 'Building Character and Massing' e) Canopies -Weather protection must be at least 4.S-feet wide as it extends from the building. Weather protection must also be provided along 7S-percent of the length of the fa~ade facing the street. The canopies shown do not meet these minimum dimensions. f) South elevation -The south elevation is visible from 1081h Ave SE and must be treated. Modulations, clerestory glazing in-lieu of ground-level glazing, brick banding, and landscaping will provide the necessary treatments for the 'back of house' fa~ade. 5. Tree Retention -The proposed site plan removes all onsite trees with the exception of a single tree on the southeast portion of the property. The City received two timely comment letters concerning the removal of the trees along the eastern border resulting in the loss of ® a buffer to the commercial zone. The mature vegetation along the eastern property extends to properties to the south and provides a buffer and transition to the adjacent single-family ~ ~. 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov neighborhood from commercial activity along lOS'h Ave SE. The development proposal requires a Conditional Use Permit, and as such, the proposal must meet decisional criteria that include: (1) appropriate location; (2) the effect on adjacent properties; (3) compatibility; and (4) noise, light, and glare (RMC 4-9-030D). The removal of the mature vegetation and reducing the width of this buffer that has provided a transition to the single- family neighborhood for decades does not meet these conditional use criteria. A revised site plan that addresses these concerns will be required. 6. Vehicle Connection -RMC 4-2-120A requires a vehicle connection site-to-site vehicle access ways, where topographically feasible, to allow a smooth flow of traffic across abutting CA lots without the need to use a street. Access may comprise the aisle between rows of parking stalls, but is not allowed between a building and a public street. The topography is likely not feasible to the south, but it is to the north. A revised site plan that provides this connection with the development, not in the future, will be required. At this time, your project has been placed "on hold" pending receipt of the requested information. Please contact me at (425) 430-6593 or mherrera@rentonwa.gov if you have any questions and/or when you are ready to schedule a resubmittal intake. appointment.

Grady Way Renton, WA 98057 Subject: Renton Firestone Project Narrative 1505 WESTLAKE AVE. N SUITE 305 SEATTLE, WA 98109 .522.9510 F 206.522.8344 WWW.PACLAND.COM The purpose of this letter is to outline the development and operation of a proposed Firestone store to be constructed at 17808 1081h Ave SE. The parcel is a total of 0.88 AC in area. Permits Required • City of Renton SEPA Determination • City of Renton Site Plan Review • City of Renton Building Permit • City of Renton Construction Permit • City of Renton Demolition Permit • City of Renton Clearing and Grading Permit • City of Renton Conditional Use Permit • Site Layout The site is within the Commercial Arterial (CA) District. The site is bordered by Jiffy Lube to the north, ;a vacant commercial building to the south, and a residential zone to the east. The site is currently developed as a 2,542 square foot Skippers restaurant and associated parking lot, sidewalks, landscaping, storm drainage, and utilities. The proposed development proposes to demolish the existing structures and perform site improvements. No wetlands, water bodies, steep slopes, or other critical areas are present on the site. Soils A geotechnical report was completed on the site by Professional Service Industries, Inc. (PSI) on June 1, 2016. The field testing revealed that on-site soils typically consist of loose to medium dense silty sands fill soils over medium dense to very dense glacial till soils. No groundwater was encountered at the boring locations during the time of field investigation, although small amounts of perched water was observed in two of the borings. Proposed Development Real Property Investors, LLC. is requesting a Site Development Plan approval. The proposed development consists of the construction of a Firestone Store service building with associated access service bays, parking lot, and landscaped areas. The use of the proposed development will be automotive vehicle service and repair. Per City of Renton Municipal Code 4-2-060, this use is allowed in the CA zone if an Administrative Conditional Use permit is obtained. Access The site has a single vehicular access point from 108'h Ave SE. This access point is a right turn in/right turn out access only. Public Improvements Rights-of-way on both 108'h Ave. SE and 1091h Ave. SE will be completed to meet the street standards for Principal Arterial Streets and Residential Access Streets, respectively. The dedication widths will be 9.0' for 108'h Ave. SE and 11.5' for 109'h Ave. SE. Although frontage improvements of half-street paving, curb, planting strip, and sidewalk have been identified, a "fee in lieu" of required frontage improvements is requested pursuant to RMC 4-9-060.9, due to the fact that there are no similar improvements in the vicinity, and there is no likelihood that improvements will be needed or required in the next five (5) years. Construction Cost The total estimated construction cost estimate for the proposed design is $1,745,000. Excavation The total amount of cut being done on the proposed site is approximately 2,910 cubic yards. Approximately 100 cubic yards of that soil will be used for fill. The net export anticipated for the site is approximately 2,810 cubic yards. Landscaping A Tree Retention Plan was created to demonstrate the significant trees on site (6-inch diameter and larger). Trees on the north, east, and south side of the parcel will be removed to accommodate the proposed clearing and grading that needs to be done on site. Approximately 27 mature trees will need to be removed on this site. The types are as follows: • 23 Coniferous trees • 4 Deciduous trees See the Tree Retention Plan for more details about which trees will be removed and which will be retained. Landscape islands will be incorporated into the proposed parking lot. Based on the amount of parking provided, a minimum of 360 square feet of interior landscaping is required. The proposed site plan contains 540 sf of interior landscaping and 10,190 sf of exterior landscaping. Proposed landscaping also incorporates shrubs and bushes. Parking Existing parking stalls on the Skipper's Restaurant site are 9'xl6.5' and 9'x18.5'. The new parking stalls will be 9'x18', with an additional two-foot overhang included to meet required 9'x20' parking stall dimension. The City of Renton requires 2.5 stalls/1000 sf of net floor area. Based on the building square footage, 19 parking stalls are required. The proposed plan identifies 24 parking stalls. Per RMC 4-4-080, a 25% increase may be granted provided quantitative support of the increase is provided. At-grade loading doors will be located on the east side of the building. A modification is requested with regards to the clear distance in front of the doors. Loading vehicles will be aligned parallel to the building rather than perpendicular, as outlined in RMC 04-04-080.J.5. Setbacks Within the Commercial Arterial (CA) zone for the site, the maximum front yard setback is 15 feet. The proposed Firestone will meet this criterion. The maximum buffer between a residential zoned street and commercial lot is 13.5'. To meet these requirements, 11.5' of the east side and 9' west side of the lot are dedicated to public access. Environment within Vicinity 2 This project is not within 100 feet of a stream or wetland or within 200 feet of any major river or lake. No part of the project proposes infrastructure above 35 feet average grade level. 3 PREAPPLICATION MEETING FOR Firestone Complete Auto Care 17808 108th Ave SE PRElG-000342 CITY OF RENTON Department of Community & Economic Development Planning Division May 19, 2016 Contact Information: Planner: Matthew Herrera, 425.430.6593 Public Works Plan Reviewer: Ann Fowler, 425.430.7382 Fire Prevention Reviewer: Corey Thomas, 425.430.7024 Building Department Reviewer: Craig Burnell, 425.430.7290 Please retain this packet throughout the course of your project as a reference.

DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT ~------Renton 0 DATE: TO: FROM: SUBJECT: MEMORANDUM May 19, 2016 Pre-Application File No. 16-000342 Matthew Herrera, Senior Planner Firestone at 1081h 17808 1081h Ave SE General: We have completed a preliminary review of the pre-application for the above- referenced development proposal. 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 17808 1081h Ave SE. The project site totals 38,234 square feet (.087 acres) in area and is located within the Commercial Arterial (CA) zoning classification. The pre-application packet indicates that the proposal is to fully redevelop the site into a 7,700 square foot Firestone vehicle service and repair with showroom, eight vehicle bays, and inventory space. The proposal includes 28 parking spaces. Access to the site is proposed via the existing curb cut along 108'h Ave SE. There appear to be no critical areas on site. Current Use: The subject parcel contains 2,200 square feet fast food restaurant. The existing structure will be removed. Development Standards: The project would be subject to RMC 4-2-120A, "Development Standards for Commercial Zoning Designations" effective at the time of complete application (noted as "CA standards" herein). Vehicle service and repair uses ore allowed within the CA zone with on approved Administrative Conditional Use Permit, provided all operations ore conducted entirely within an enclosed structure. The property is also located within the Urban Design District 'D' overlay, and therefore subject to additional design elements. Proposals should have unique, identifiable design treatment in terms of landscaping, building design and orientation, signage, and street furniture.

Lot Coverage -The CA zone allows a maximum building coverage of 65 percent. Setbacks -Setbacks are the distance between the building and the property line or any private access easement. Setback requirements in the CA zone are as follows: 15 feet minimum for the front yard but may be reduced to zero feet through the Site Plan Review process provided blank walls are not located within the reduced setback; a 20 foCJJ_rD,ciximum front yard setback; and no rear or side yard setbacks with the exception of the. portion ab;tting the residential zoned property on the northeast, which requires a 15 foot setback.-fhe-structufe appears to be setback nearly 60-feet from the existing sidewalk. The maximum setback may be modified by the Reviewing Official through the site development pion review process if the applicant con demonstrate that the site development plan meets the following criteria: a. Orients development to the pedestrian through such measures as providing pedestrian walkways beyond those required by the Renton Municipal Code (RMC}, encouraging pedestrian amenities and supporting alternatives to single occupant vehicle /SOV} transportation; and b. Creates o low scale streetscape through such measures as fostering distinctive architecture and mitigating the visual dominance of extensive and unbroken parking along the street front; and c. Promotes safety and visibility through such measures as discouraging the creation of hidden spaces, minimizing conflict between pedestrian and traffic and ensuring adequate setbacks to accommodate required parking and/or access that could not be provided otherwise. The proposal does not appear to comply with the above mentioned criteria. Therefore, staff would likely not be supportive of an increase in the maximum setback to the extent proposed. Gross Floor Area -There is no maximum gross floor area for commercial uses within the CA zone. Building Height -The maximum building height that would be allowed in the CA zone is 50 feet for commercial only structures. No height issues were found with your submittal. Screening -Screening must be provided for all surface-mounted and roof top utility and mechanical equipment. The site plan application will need to include elevations and details for the proposed methods of screening. See RMC 4-4-095 for utility and mechanical equipment screening options. Refuse and Recycling Areas -Refuse and recycling areas shall meet the requirements of RMC 4- 4-090, "Refuse and Recyclables Standards." For commercial developments a minimum of 5 square feet per every 1,000 square feet of building gross floor area shall be provided for recyclable deposit areas and a minimum of 10 square feet per 1,000 square feet of building gross floor area shall be provided for refuse deposit areas with a total minimum area of 100 square feet. Outdoor refuse and recyclables deposit areas and collection points shall not be located within any required setback or landscJpe areas and shall not be located within fifty feet (oO') of J lot zoned residential, except by approval through the site development plan review precess. The applicant would be required to submit a site plan depicting a refuse and recyclable area compliant with RMC 4-4-090 at the time of Site Plan Application. See Urban Design Regulations comment section for additional garbage enclosure requirements. Firestone at 108th Page 3 of7 May 19, 2016 Landscaping-All portions of the 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, except for walkways and driveways. A 15 foot wide partially sight- obscuring landscape visual barrier or 10 foot wide fully sight obscuring landscaped visual barrier is required along the rear property line and abutting the residential parcel on the northeast portion of the property. The site plan does nat identify the required landscaping on the northeast corner abutting the residential property. Surface parking lots with 15 to 50 stalls shall provide an additional 15 square feet of landscaping for eaciµJar-k,ng stall. There shall also be no more than 50 feet between parking stalls and an interior 'parking lot landscape area. The site plan does show any space for internal lot landscaping. Perimeter parking lot landscaping shall be at least 10 feet in width as measured from the street right-of-way. Trees shall be two inches in diameter at breast height at an average minimum rate of one tree per thirty lineal feet of street frontage. Shrubs at the minimum rate of one per twenty square feet of landscaped area. Up to fifty 50 percent of shrubs may be deciduous. Please refer to landscape regulations (RMC 4-4-070) for additional general and specific landscape requirements. A landscape plan shall be submitted at the time of application for Site Plan Review. Tree Preservation -If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory and a tree retention plan along with an arborist report, tree retention plan and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. The tree retention plan must show preservation of at least 10% of significant trees, and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be retained (RMC 4- 4-130Hl.a). When the required number of protected trees cannot be retained, replacement trees, with at least a two-inch (2") caliper or an evergreen at least six feet (6') tall, shall be planted at a rate of twelve (12) caliper inches of new trees to replace each protected tree removed. The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that an insufficient number of trees can be retained. Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than 20%; significant trees adjacent to critical areas and their associated buffers; and significant trees over 60' in height or greater than 18" caliper. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non-native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. Firestone at 108th Page4 of7 May 19, 2016 The Administrator may require independent review of any land use application that involves tree removal and land clearing at the City's discretion. A formal tree retention plan would be reviewed at the time of Building Permit application. Parking -The minimum and maximum number of parking spaces is 2.5 per 1,000 square feet of net floor area. Assuming the 7,700 square foot facility is inclusive of net floor area as defined by RMC 4-11-060, the site would require 19 spaces. The submittal materials indicate a total of 28 surface parking spaces would be provided on site. The proposal exceeds the maximum surface parking requirements. A 25 percent reduction or increase from the minimum or maximum number of parking spaces may be granted for nonresidential uses through site plan review if the applicant can justify the modification to the satisfaction of the Administrator. Justification might include, but is not limited to, quantitative information such as sales receipts, documentation of customer frequency, and parking standards of nearby cities. Modifications beyond 25 percent must be requested via the formal modification process [RMC 4-9-250D) The proposal would also be required to provide bicycle parking based on 10 percent of the required number of parking stalls for commercial uses. See RMC 4-4-0BOFllb for bicycle parking standards. Surface parking is not permitted between the building and street. See Urban Design Regulations comment section. Surface parking stalls must be a minimum of 9 feet x 20 feet, compact dimensions of SY, feet x 16 feet, and parallel stall dimensions of 9 feet x 23 feet; compact surface parking spaces shall not account for more than 30 percent of the spaces in the surface parking lots. Minimum width of drive aisles for 90 degree parking is 24-feet. Parking dimensions and minimum aisle width appear to comply. 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. Vehicle Access and Loading: Driveways shall not be closer than 5-feet to any property line. Driveway widths are limited to 40 percent of the street frontage and not exceed 30-feet. See RMC 4-4-080! for complete driveway standards. Buildings which utilize ground level service or loading doors shall provide a minimum of 45-feet of clear maneuvering area in front of each door. The garbage enclosure is located within this clear zone area on the submitted site plan and therefore out of compliance. onnectian shall also be provided for site-to-site vehicle access ways, where topogrophically asible, to allow a smooth flow of traffic across abutting CA parcels without the need to use a eet. Signage -Only one freestanding business sign (restricted to monument/ground signs only) is permitted per street frontage, however pole signs are not permitted within the CA zone. Each sign shall not exceed an area greater than one and one-half square feet for each lineal foot of property frontage that is occupied by the business. In no case shall the sign exceed a total of 300 square feet (150 square feet per face). The ground/monument sign is limited to 5 feet in height. In addition to the permitted freestanding sign, wall signs with a copy area not exceeding Firestone at 108th Page 5 of7 May 19, 2016 20% of the fa<;ade, to which it is applied, are also permitted. See RMC 4-4-100 for additional sign requirements. Urban Design Regulations: The subject property is within the Urban Design District 'D' and compliance with District D Urban Design Regulations is required RMC 4-3-100. In general the regulations encourage building design that is unique and urban in character, comfortable on a human scale, and uses appropriate building materials that are suitable for the Pacific Northwest climate and to discourage franchise retail architecture.

( Environmental Review: The proposed building is in excess of 4,000 square feet and therefore \__exceeds the categorical exemption threshold for minor new construction. Firestone at 108th Page 6 of 7 May 19, 2016 The proposed project would be subject to Washington State Environmental Policy Act {SEPA) 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: In addition to environmental review the following land use permits would be required: (1) Administrative Conditional Use Permit; and (2) Administrative Site Plan Review. The proposal will require an Administrative Conditional Use Permit. Conditional Use Permits allow for review of certain uses with special characteristics that may not generally be appropriate within a zoning district, but may be permitted subject to conditions and mitigation measures that protect public health, safety and welfare and ensure compatibility with other uses in the district. Decisional criteria for the conditional use permit are itemized in RMC 4-9- 0300. It is the applicant's responsibility to identify how the proposal meets the decisional criteria. The proposal would require Administrative Site Plan Approval. The purpose of the site plan review process is to analyze the detailed arrangement of project elements to mitigate negative impacts where necessary to ensure project compatibility with the physical characteristics of a site and with the surrounding area. Site plan review ensures quality development consistent with City goals and policies. Site plan review analyzes elements including, but not limited to, site layout, building orientation and design, pedestrian and vehicular environment, landscaping, natural features of the site, screening and buffering, parking and loading facilities, and illumination to ensure compatibility with potential future development. The applicant will also be subject to Design Review as part of the Site Plan Review and a Design Checklist shall be completed and submitted as part of the application materials (see attached). There may be other approvals (modifications, variances, etc.) required depending on the scope of the proposal. All applications can be reviewed concurrently in an estimated time frame of 9- 8.weeks once a complete application is accepted. The Conditional Use Permit application fee is $1,000. The Site Plan Review application fee is $1,500. The application fee for SEPA Review (Environmental Checklist) is $1,000. The application fee for the parking modification is $150. There is an additional 3% technology fee at the time of land use application for a grand total of $3,759.50. Detailed information regarding the land use application submittal is provided in the attached handouts. In addition to the required land use permits, separate construction, building 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 appeal periods. Public Information Sign: The applicant is required to install a proposed land use action sign on the subject property per the specifications provided in the accompanied public information sign handout. The applicant is solely responsible for the construction, installation, maintenance, removal, and any costs associated with the sign. Neighborhood Meeting: Projects in excess of 10 million dollars require the applicant to conduct an independent neighborhood meeting and provide a public outreach sign. Please contact me for further information should the project exceed the 10 million dollar threshold. Firestone at 1081h Page7of7 May 19, 2016 Impact Fees: In addition to the applicable building and construction fees, the following impact fees would be required prior to the issuance of building permits: • A Fire impact fee currently assessed at $0.61 per square foot of commercial space • A Transportation impact fee will be based on the ITE manual Next Steps: When the formal application materials are complete, the applicant is strongly encouraged to have one copy of the application materials pre-screened at the 6th floor front counter prior to submitting the complete application package.

N SUITE 305 SEATILE, WA 98109 522.9510 F 205.522.8344 WWW PACLANO COM Subject: Renton Firestone Refuse Enclosure Vertical Clearance Modification The project is requesting to Renton Municipal Code (RMC) 4-4-090.C.9. Requirement RMC 4-4-090.C.9 states that "the gate opening for any separate building or other roofed structure used primarily as a refuse or recyclables deposit area/collection point shall have a vertical clearance of at least fifteen feet (15')." Modification The project has proposed a refuse enclosure having a height of 8'. Per communication with the City of Renton Planning Department, the City's waste management services do not require the 15' vertical clearance to adequately collect refuse. Furthermore, incorporating the full 15' clear height for the trash enclosure would be much costlier and undesirable from a visual standpoint. Criteria Compliance a. The intent of the vertical clearance requirement is to ensure that waste management services are able to access the refuse enclosure for pickup. Since they are able to do so without the 15' vertical clearance, the modification will continue to meet the intent of the code. b. The modification will not result in any undue negative impacts to safety, function, appearance, or environmental protection and maintainability. c. The modification will not be injurious to other properties in the vicinity, as all refuse pickup will be performed on the subject property. d. Since waste management services will still be able to access the enclosure and perform refuse pickup adequately, the proposed design will continue to meet the intent of the code. e. Due to the added expense and visual impacts associated with the full 15' vertical clearance, the reduced height is justified for the enclosure. f. The modification will not create adverse impacts to other properties in the vicinity, as all refuse pickup will be performed on the subject property. October 6, 2016 City of Renton 1055 S. Grady Way Renton, WA 98057 1505 WESTLAKE AVE N SUITE 305 SEATILE, WA 98109 Subject: Renton Firestone Loading Clear Area Modification -,.522.9510 F 206.522.8344 WWW.PACIJ-\ND.COM The project is requesting a modification to Renton Municipal Code (RMC) 4-4-080.J.5, which requires 45' clear area perpendicular to the loading door. Requirement Per RMC 4-4-080.J.5, "buildings which utilize ground level service or loading doors shall provide a minimum of forty five feet (45') of clear maneuvering area in front of each door." Modification Loading for the proposed development will be performed by delivery trucks backing up to the loading doors in the north-south direction (parallel to the building). As such, the need for a 45' clear area perpendicular to the door is not applicable. A large maneuvering area is incorporated to provide delivery trucks adequate room to make the necessary turning movements. Criteria Compliance a. The purpose of the loading clear area requirement is to ensure that adequate space is provided to perform loading operations. Due to the manner in which the proposed deliveries are to be made, the modification will continue to meet the intent of the code. b. The modification will not result in any undue negative impacts to safety, function, appearance, or environmental protection and maintainability. c. The modification will not be injurious to other properties in the vicinity, as all loading operations will be performed on the subject property. d. As stated above, adequate clear space will be provided in the north-south directions, allowing loading to be performed effectively and thus meeting the intent of the code. e. Due to the manner in which loading is proposed, a 45' clear space perpendicular to the building is not appropriate. Instead, this area will be utilized to provide space for a trash enclosure and parking. f. The modification will not create adverse impacts to other properties in the vicinity, as all loading operations will be performed on the subject property. October 6, 2016 City of Renton 1055 S.

Requirement Per RMC4-6-060, the proposed commercial development requires associated public street improvements along project frontages. These improvements, as outlined in RMC 4-6-060 and stated in the project pre- application meeting requirements, include 13' half-street paving, 0.5' curb, 8' planting strip, 5' sidewalk, street trees, and storm drainage improvements along 109'h Ave. SE. Modification Pursuant to RMC 4-9-060.9, the project proposes to pay a fee in lieu of the required street improvements. As outlined in RMC 4-9-060.9.c, the City may accept a fee in lieu of street improvements if "there are no similar improvements in the vicinity and there is no likelihood that the improvements will be needed or required in the next five (5) years". This is the case for the frontage along 1091h Ave. SE. There are no existing frontage improvements along 109'h Ave. SE. Criteria Compliance a. Due to the lack of existing improvements similar to the required street improvements along the 109'h Ave. SE frontage, the project's proposal to pay a fee in lieu of the required frontage improvements is appropriate as outlined in RMC 4-9-060. b. The modification will not result in any undue negative impacts to safety, function, appearance, or environmental protection and maintainability. c. The modification will not be injurious to other properties in the vicinity, as the frontage will remain in its existing condition. d. As described above, the fee in lieu of frontage improvements is allowed under the Renton Municipal Code, and meets the intent and purposes of the code. e. Based on the existing frontage improvements, fee in lieu of frontage improvements is appropriate, as there are no similar existing improvements in the vicinity. f. The modification will not create adverse impacts to other properties in the vicinity, as the frontage will remain in its existing condition. September 30, 2016 City of Renton 1055 S.

Proposed Construction The construction for the proposed Firestone store in Renton, WA is estimated to start during Summer of 2017 be completed during Fall of 2017. Construction Hours All site improvements and construction activities will occur between the hours of 7:00 a.m. and 8:00 p.m., Monday through Friday, and 9:00 a.m. and 8:00 p.m. on Saturdays and Sundays. Construction Mitigation Measures Firestone will implement construction best management practices, including the following, to reduce construction noise: • Locate stationary construction equipment as far from adjacent occupied buildings as possible. • Select routes for movement of construction related vehicles and equipment so that noise sensitive areas, including outdoor recreation areas, are avoided as much as possible. • All construction equipment will meet Department of Motor Vehicle (DMV) noise standards and shall be equipped with muffling devices. • Prior to construction, the applicant will post on the site the allowable hours of construction activity. Firestone will implement the following mitigation measures during all construction phases to reduce impacts associated with construction dust to the extent feasible, as determined by the City Engineer. • Water all active construction areas up to twice daily. • Cover all trucks hauling soil, sand, and other loose materials to or from the Project Area. • Pave, apply water up to three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites. • Sweep (with water sweepers) if visible soil material is carried onto adjacent public streets. • Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas (previously graded areas inactive for ten days or more). • Enclose, cover, water up to twice daily or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). • Limit traffic speeds on unpaved roads to 15 mph. • Install sandbags or other erosion control measures to prevent silt runoff to public roadways. • Replant vegetation in distributed areas as quickly as possible. Firestone will develop and provide a construction access plan to be reviewed and approved by the city Engineer. This plan will include, at a minimum, the following construction traffic management strategies for each phase of development: • A set of comprehensive traffic control measures, including the scheduling of major truck trips and deliveries to avoid peak traffic hours, detour signs and flag persons if required, lane closure procedures, signs, cones for drivers, and designated construction access routes. • Provisions for parking spaces for all construction workers for each phase of constructions. • The location of construction staging areas for materials, equipment, and vehicles. • The identification of haul routes for the movement of construction vehicles that would minimize impacts on vehicular traffic, circulation, and safety; and a provision for monitoring surface streets used for haul routes so that any damage and debris attributable to the haul tracks can be identified and corrected. 2 RIGHT-OF-WAY DEDICATION GRANTOR'S PROPERTY THE REAL PROPERTY (HEREINAFTER CALLED "TOTAL PROPERTY") IN WHICH THE RIGHT- OF-WAY IS TO BE DEDICATED IS LEGALLY DESCRIBED AS FOLLOWS: THE SOUTH 132 FEET OF THE NORTH SIX-TENTHS OF THAT PORTION OF THE WEST HALF OF THE WEST HALF OF THE NORTHWEST QUARTER OF THE NORTHEAST QUARTER OF SECTION 32, TOWNSHIP 23 NORTH, RANGE 5 EAST, W.M., IN KING COUNTY, WASHINGTON, LYING SOUTH OF THE NORTH 30 FEET THEREOF; EXCEPT THAT PORTION LYING WESTERLY OF A LINE BEGINNING OPPOSITE HIGHWAY ENGINEER'S STATION 315 + 81 AND 40 FEET EASTERLY OF THE CENTERLINE OF HIGHWAY SR 515, RENTON VICINITY; (SOUTHEAST 196TH STREET TO CARR ROAD); THENCE NORTHERLY IN A STRAIGHT LINE TO A POINT OPPOSITE HIGHWAY ENGINEER'S STATION 318 + 41 AND 45 FEET EASTERLY OF SAID CENTERLINE, AND END OF SAID LINE AS CONVEYED TO THE STATE OF WASHINGTON BY DEEDS RECORDED AUGUST 02, 1972, UNDER RECORDING NOS. 7208020358 AND 7207110553, IN KING COUNTY, WASHINGTON.

TENW SUBJECT: Renton Firestone -Trip Generation PREl 6-000342 TENW Project No. 5313 This memorandum summarizes the preliminary traffic information for the proposed Firestone Complete Auto Care project located at 17808 I OS 1h Ave SE in Renton, Washington. This memo includes a project description and trip generation estimate. We are requesting your review and approval of this information and confirmation that a traffic impact analysis will not be required for this project. Project Description The Renton Firestone site is located an the east side of l 08 1h Ave SE 117808 l 08 1h Ave SE, see site vicinity map in Attachment AJ. The existing site includes a fast-food restaurant with drive-through window (Skippers) totaling 2,200 square feet, which would be removed. The proposed Firestone Complete Auto Care project would include up to 7,700 square feet of 'ire soles/auto care use. Access lo the Firestone project is proposed to be provided via one right-in, right-out only driveway on I 08 1h Ave SE in approximately the same location as the existing driveway lo Skippers. A preliminary site plan is provided in Attachment 8. The project is expected to be occupied in 2017. Trip Generation The trip generation estimates for the proposed Firestone project were based on methodology in the Institute of Transportation Engineers (ITEJ Trip Genera/ion Manual, 9th edition, for Tire Store (LUC 848) and Fast-Faoo Restaurant with Drive-Through Window (LUC 934). The net new trip generation was calculated by subtracting the trips from the restaurant to be removed from the trips generated by the proposed Firestone. The resulting net new weekday daily, AM and PM peak hour trips ore summarized in Table I. A detailed trip generation estimate is included in Attachment C.

WA 98004 J Office 1425) 889-6747 Renton Firestone -Trip Generation As shown in Table l, the proposed Firestone project is estimated to result in a net reduction in weekday daily trips [-407 trips) wilh 16 net new trips occurring during the weekday AM peak hour [IO enlering, 6 exiting). and a net reduction of net new trips [-13 trips) occurring during the weekday PM peak hour (-9 entering, -4 exiting). As a conservative assumption, no credit was token for trips from the existing reslauronl during the AM peak hour as the current restaurant (Skippers) opens after 9 AM. Next Steps The proposed Renlon Firestone project would generate less than 20 net new trips during the weekday AM and PM peak hours. Therefore, based on the Ci!y's guidelines, no additional traffic analysis is required for !his development. We look forvvard to your review and approval of our !rip generation estimates and consensus that no additional traffic analysis is necessary.

The site is bordered by 1081h Ave SE/WA 515 to the west, Jiffy Lube to the north, a vacant commercial building to the south, and a 109th Ave SE to the east. The site is currently developed as the Skipper's Seafood and Chowder House, which has a building footprint of 2,552 square feet, with associated parking and landscaping. The entire lot is approximately 0.88 acres in size. This project proposes to demolish the existing restaurant and parking lot, then redevelop the site to become a Firestone Complete Auto Care. The project site lies within the Lower Green River Subwatershed, which is part of the Green/Duwamish Watershed. It is in the City of Renton Black River drainage basin. The project site is located in the City of Renton Commercial Mixed Use Overlay District (Community Planning area). The property is zoned CA (commercial arterial). Design Criteria: The City of Renton uses the King County Surface Water Management Design Manual (KCSWDM), 2009 Edition, as adopted by the City of Renton and the City of Renton Amendments to the King County Surface Water Design Manual, dated February 2010. The existing site is developed and primarily impervious with the exception of landscape islands and an undeveloped piece of land between the parking lot and 109th Ave SE. The overall impervious area will increase about 3,590 SF due to this project, which will require additional detention. Additional water quality treatment will be provided to meet the requirements of Core Requirement #8 as the project will increase the pollution generating impervious surface by more than 5,000 SF.

The proposed grading will send water from the Northeast corner of the site toward the West side of the site. There is currently a storm pipe that runs west from 109th Ave SE toward the building. The proposed pipe will move north toward the Northeast corner of the site. This pipe will convey water toward the existing water structures on the Northwest corner. Stormwater will also collect into catch basins along the valley on the east and north side of the building and then be conveyed to the Northwest corner of the site to the Modular Wetland for water quality treatment. Then the water will be sent to the detention vault for storage. Then the water will travel to the existing storm structures in the Northwest corner of the site. Conclusion: The proposed stormwater management system for this project has been designed in accordance with regulatory criteria described above and is consistent with sound engineering practice. The site has been analyzed to determine the requirements for detention and water quality treatment, and no significant adverse impacts to the stormwater management system are expected as a result of the proposed development.

It is i n the City of Renton Black Rive r dra inage bas in. Existing Subbasins The design of the ex isting si te used a single bas i n with an area of 0.88 acres. Th e southeast portion of the site of th e highest in elevation at 410'. Th e area gradua ll y sloped west until the finished floo r of the building about 402'. The northeast side of th e site starts at an elevation of 408' and slopes downwa rd toward the west side of the site where it has an elevation of 400'. This whole subbasin crea tes a drainage system that allows water to flow from east to west. The Northwest corner of the site has a catch basin that conveyed water into the mun icipal stormwater system. There is another discharge at the Southwest corner of the site due to the val ley that runs east to west along the southern part of t h e si t e. Proposed Subbasins The proposed storm drainage system will be composed of the same approximate subbasins as th e existi ng. See Appendix A Exh ibi t B-Pr oposed Subbasin, detai l ing the proposed subbasins. As shown in Table 2 -Site A r eas, the impervious area is decreasing as a result of thi s development.

Soils Websoil Su rvey Figure 3 -Site Soils (USDA Web Soil Survey Map) The site is mapped as A ld erwood grave ll y sandy loam Oto 8 percent slopes (AgB) and A lderwood gravelly sandy loam 8 to 15 percent slopes (Ag() according to the USDA Natural Resource Conservation Service, Web Soi l Survey for King County Area, Wash i ngton. Geotechnical Report The following i nformation was gathered from a report created by Zi ppe r Geo Associates, LLC. on August 29, 2016. 4 feet deep under the surface, ZGA's in fi ltra t ion test recorded that the soi l observed was glacial ti l l with medium dense, li ght brown w ith some oxidation, sandy loam with gravel. Underneath this so il was u nwea thered g l acia l t ill consist i ng of dense, tan, sandy loam with gravel. The b ottom of the infiltration test was at 8 fe et. The report showed dense, tan, unweathered glacia l till at this depth. PACLAND Project #10439013 Page 11 Firestone Complete Auto Care Technical Information Report Renton, Washington No groundwater was observed during the infiltration test. There were also no signs that the seasonal groundwater may be higher than when observed. ZGA performed a single small-scale Pilot Infiltration Test per standard of the Storm Water Manual. The results of the test were that the infiltration test was approximately 0.21 inches/hour. According to Table 3.7 in the City of Renton's Amendments to the King County Storm Water Design Manual, a correction factor of 4 must be used to derive the design infiltration rate from the observed short term infiltration rate. After applying this correction factor, the site has a design infiltration rate of 0.05 in/hr. PACLAND Project #10439013 Page 12 Firestone Complete Auto Care Technical Information Report Renton, Washington Section 2-Conditions and Requirements As required by the 2009 King County Surface Water Design Manual (KCSWDM) and City of Renton Amendment, this project is subject to a full drainage review. Therefore, the storm drainage design for this project is required to comply with all eight (8) Core Requirements, and six (6) Special Requirements. The requirements have been met as follows: Core Requirement #1: Discharge at Natural Location All surface and storm water runoff from a project must be discharged at the natural location so as not to be diverted onto or away from downstream properties. The manner in which runoff is discharged from the project site must not create a significant adverse impact to downhill properties or drainage systems. Response: Onsite runoff will be collected, conveyed and, when necessary, treated. All onsite runoff is subsequently conveyed to the City of Renton storm water system. The city system discharges northwest of the site into Panther Creek. No downstream impacts are anticipated as a result of the proposed improvements as the impervious area will remain approximately the same. Core Requirement #2: Off-site Analysis All proposed projects must submit an offsite analysis report that assesses potential offsite drainage and water quality impacts associated with development of the project site and propose appropriate mitigation of those impacts. The initial permit submittal shall include, at minimum, a Level 2 downstream analysis. Response: See Section 3 of this report for a complete off-site analysis. A Level 2 downstream analysis will be submitted upon civil plan submittal. Core Requirement #3: Flow Control All proposed projects, including redevelopment projects, must provide onsite flow control facilities or flow control BMPs or both to mitigate the impacts of storm and surface runoff generated by new impervious surface, new pervious surface, and replaced impervious surface targeted for flow mitigation. Response: (Waiting on KCRTS) Per the exceptions listed in section 1.2.3.1-A of the City of Renton Amendment to the KCSWDM the project is exempt from flow control requirements as it doesn't increase the 100-year peak flow and is not expected to significantly impact a critical area, or cause severe flooding or erosion problems. The proposed 12.28 acre site generates 4.84 cfs, a 0.17 cfs decrease in the 100-year peak flow rate from the existing site conditions. Therefore, additional flow control facilities, beyond the existing storm water ponds and flow control structure, are not proposed as part of this project. A PACLAND Project #10439013 Page 13 Firestone Complete Auto Care Technical Information Report Renton, Washington detailed summary and analysis of the existing and proposed conditions is provided in Section 4 of this report. Core Requirement #4: Conveyance System All engineered conveyance system elements for proposed projects must be analyzed, designed, and constructed to provide a minimum level of protection against overtopping, flooding, erosion, and structural failure. Response: Portions of the existing conveyance system will be reused as port of this project with additional conveyance added ta accommodate the new building configuration and site layout. The proposed conveyance system hos been designed to convey the 100-yeor peak flow. Core Requirement #5: Erosion and Sediment Control All proposed projects that will clear, grade, or otherwise disturb the site must provide erosion and sediment controls to prevent, to the maximum extent practicable, the transport of sediment from the project site to downstream drainage facilities, water resources, and adjacent properties. Both temporary and permanent ESC measures shall be implemented. Response: Erosion and sediment control requirements will be an integral part of the project construction documents. These measures will include methods to reduce erosion of onsite site soils and to prevent sediments from inadvertently leaving the project site. Additionally, the ESC measures will prevent sediment-laden discharge from entering the wetland or existing stormwoter water quality or flow control facilities. Core Requirement #6: Maintenance and Operations Maintenance and operation of all drainage facilities is the responsibility of the property owner, except those facilities for which the City of Renton assumes maintenance and operation, and must be maintained and operated in accordance with King County or other maintenance standards as approved by the City of Renton. Response: An Operations and Maintenance Manual is included in this report-see Section 10. Core Requirement #7: Financial Guarantees and Liability In accordance with RMC 4-6-030J, RDSD shall require all persons constructing any surface water facilities (including flow control/water quality facilities, conveyance systems, erosion control, and road drainage), to post with the City of Renton a bond, assignment of funds or certified check. The applicant must also maintain liability insurance. Response: See Section 9-Bond Quantities, Facility Summaries, and Declaration of Covenant. The Site Improvement Bond Quantity Worksheet and Declarations of Covenants will be submitted upon approval of the Building Permit plans. PACLAND Project #10439013 Page 14 Firestone Complete Auto Care Technical Information Report Renton, Washington Core Requirement #8: Water Quality All proposed projects, including redevelopment projects, must provide water quality (WQ) facilities to treat the runoff from those new and replaced pollution-generating impervious surfaces and new pollution-generating pervious surfaces targeted for treatment. Response: The proposed project improvements will decrease the pollution generating impervious surface (PGIS) by 0.11 AC The site currently hos accommodation for 0.42 AC of PGIS. Enhanced Basic Treatment is required if more than 50% of the runoff that drains to the proposed treatment facility is from commercial land use. Additional Enhanced Basic Water Quality treatment will be provided for the increase in impervious surfaces on site. Additionally, on oil/water separator, which will discharge to the sanitary sewer system, will be provided for discharges from the building. A detailed summary and analysis of the water quality basin and design is provided in Section 4 of this report. Special Requirement #1: Other Adopted Area-Specific Requirements The City of Renton may apply requirements for controlling drainage on an area-specific basis. Potential other adopted area-specific requirements may include: Master Drainage Plans, Basin Plans, Stormwater Compliance Plans, etc. Response: The project site is within Washington State Water Resource Inventory Area 9: Green/Duwomish and Centro/ Puget Sound Watershed Salmon Habitat Recovery. However, the proposed project will hove no effect on any salmon habitats. The project site does not lie within any City of Renton Moster Drainage or Basin Plans. Special Requirement #2: Flood Hazard Area Delineation If a proposed project contains or is adjacent to a flood hazard area as determined by the Renton Department of Storm Drainage, the project must determine those components that are applicable and delineate them on the project's site improvement plans and recorded maps. Response: The project site does not lie within or adjacent to a City of Renton Flood Hazard Area (determined by FEMA FIRM Panel 53033C0979F dated Moy 16, 1995) and therefore does not need to apply the provisions of this requirement. Special Requirement #3: Flood Protection Facilities Proper analysis, design, and construction are necessary to protect against the potentially catastrophic consequences if flood protection facilities such as levees and revetments should fail. Response: The proposed project will not rely on an existing flood protection facility, or modify or construct a new flood protection facility. Special Requirement #4: Source Control PACLAND Project #10439013 Page 15 Firestone Complete Auto Care Technical Information Report Renton, Washington If a proposed project requires a commercial building or commercial site development permit then the water quality source controls applicable to the proposed project shall be applied in accordance with the King County Starmwater Pollution Prevention Manual and Renton Municipal Code N. Response: Water quality source controls will be applied in accordance with the KCSWDM and Renton Municipal Cade IV. A pollution prevention plan has been included in section 8 of this report. Special Requirement #5: Oil Control Projects proposing to develop or redevelop a high-use site must provide oil control in addition to other water quality controls required. Response: High use sites area defined as a commercial or industrial site that (1) hos on expected average doily traffic count equal ta or greater than 100 vehicles/1,000 SF of grass building area: (2) is subject ta petroleum storage in excess of 1,500 go/Ions per year; (3) is subject ta use, storage, or maintenance of a fleet of 25 or more diesel vehicles. The proposed development does not exceed any of these thresholds, and is therefore not required to provide oil contra/. Special Requirement #6: Aquifer Protection Area If a proposed project is located within the Aquifer Protection Area as identified in the RMC 4-3- 050, this special requirement requires the project to determine those components that are applicable and delineate them on the project's site improvement plans. Response: The project is not located within an Aquifer Protection Area, and therefore this requirement does not apply.

Figure 4 -Downstream Area (Renton COR Maps) PACLAND Proj ect #10439013 Page 17 Firestone Complete Auto Care Technical Information Report Renton, Washington Conclusion The existing downstream stormwater facilities have been analyzed and after discussions with the City Engineer, as long as the project site does not increase the overall impervious area from its existing conditions, it is expected that there will be no adverse impacts to the downstream facilities because the developed peak flow rate leaving the developed site will be less than the existing peak flow rate. See Section 4 for further explanation. PACLAND Project #10439013 Page 18 Firestone Complete Auto Care Technical Information Report Renton, Washington Section 4-Flow Control and Water Quality Facility Analysis The City of Renton Amendment to the KCSWDM applies flow control standards based on geographic areas as determined by the Flow Control Application Map. The project site lies within a Conservation Flow Control Area. This requires a level 2 downstream analysis. This area requires peak runoff control within the Flow Control Duration Standard Matching Existing Site Conditions area such that it matches the flow duration of predeveloped rates for the existing site conditions over the range of flows extending from 50% of 2-year up to the full SO-year flow. This matches the flow duration of predeveloped rates for the existing site conditions over the range of flows extending from 50% of 2-year up to the full SO-year flow. Hydrologic Analysis The existing and proposed site conditions were evaluated using both the King County Runoff Time Series (KCRTS) The detailed KCRTS output has been included in Appendix C -Design Calculations. The historic 1-hour duration in the Sea-Tac rainfall region (location scale factor ST-1.0) was used to model runoff in KCRTS. Existing Site Hydrology The existing site includes a storm drainage system designed to collect storm water at strategically placed catch basins throughout the site. The storm water is then conveyed through underground pipes to the northwest corner of the site where it ties into the Renton Municipal System. The municipal stormwater system routes to a discharge point of Panther Creek across SE Carr Rd. The existing detention basin was designed to release flows at or below the pre- developed rates for the 2, 10, and 100 year storms. The pre-developed conditions and existing peak runoff rates for the project site area are shown in Tables 4 and 5 below. Existing peak runoff rates were determined using the King County Runoff Time Series modeling software and the calculations can be found in Appendix C. Table 4 Pre-Developed (Existing) Conditions Area Condition 7.94 AC Pavement (PGIS) 2.74 AC Landscape/Wetland 1.42 AC Roof Table 5 Existina Peak Runoff Rate Event l Rate (cfs) PACLAND Project #10439013 Page 19 Firestone Complete Auto Care Technical Information Report Renton, Washington 2-vear 2.54 10-vear 3.03 100-vear 5.01 Developed Site Hydrology The proposed project will have similar hydrology to the existing site. It is anticipated that the existing systems (conveyance, detention, and treatment) will be utilized as the overall site hydrology and division of subbasins will remain approximately the same. The amount of pervious area is increasing due to a reduction in building size and additional landscaping, however the site PGIS will be increased as a result of the decrease in building size. The post- developed conditions and un-detained peak runoff rates for the entire attributed basin area (12.28 acres) are shown in Tables 6 and 7 below. Developed peak runoff rates were determined using the King County Runoff Time Series modeling software and the calculations can be found in Appendix C. Table 6 Post-Developed Conditions Area Condition 8.22 AC Pavement (PGIS) 3.60 AC Landscape/Wetland 046 AC Roof Table 7 Developed Peak Runoff Rate Event Rate (cfs) 2-vear 2.43 10-year 2.91 100-year 4.84 Flow Control Analysis The post developed 100-year peak runoff rate for the overall site decreases by 0.17 cfs from the existing condition. Because the project is located in the Peak Rate Flow Control Standard area and does not increase its developed 100-year peak runoff rate, any additional flow control facility requirement is waived for this project. The existing flow control facilities consist of the following structures inside of a 54-inch diameter catch basin manhole; a 1-inch diameter orifice with an outlet elevation of 10.87, a 3.5-inch diameter orifice with an outlet elevation of 15.00, a 6-inch diameter elbow with an outlet elevation of 15.50, and a 15-inch diameter restrictor with an overflow elevation of 16.50. The control structure discharges to a 15-inch storm drain pipe before connecting into the Renton PACLAND Project #10439013 Page 20 Firestone Complete Auto Care Technical Information Report Renton, Washington Municipal storm system. See Appendix B for the Act III Theater Drainage Report, which includes illustrations and calculations for the existing flow control system. Water Quality System The proposed redevelopment includes demolition of the existing theater; construction of the sales, service, car wash, and presentation buildings, reconfigurations of landscape islands and repaving of the existing parking area. The roofs of the proposed buildings will be considered non pollution-generating impervious surfaces (NPGIS). While the overall impervious area of the site will be reduced as part of this project, the amount of pollution-generating impervious surfaces (PGIS) will be increasing since the existing building footprint will be replaced with new PGIS. There are two existing grass-lined biofiltration swales which discharge to three water quality ponds in series. The swales and water quality ponds were sized for the existing impervious area, as detailed by the drainage report by Horton Davis and Associates. The project will add 0.28 AC of new PGIS. This is more than 5,000 SF of new PGIS; therefore additional water quality treatment will be provided. Two Modular Wetland Stormwater Biofiltration Systems are proposed to meet the Enhanced Basic Water requirement in King County Surface Water Design Manual. The Enhanced basic treatment will be provided for the increased PGIS. New PG/5 Areas The new PGIS is a result of the revisions to the site layout and the reduced building size. It isn't possible to collect the exact area of new PGIS however the majority of the new PGIS, located within the existing building footprint, will be treated. There are two Water Quality Basins within the proposed vehicle storage area and will be greater in size than the increase in the new PGIS. The total area in the proposed Water Quality Basins is 1.14 AC. Exhibit 3 -Water Quality Basin in Appendix A depicts the area to be treated. Tables 8 and 9, below, contain the developed conditions of each treatment basins as well as the water quality design flow rate (60% of the developed 2-year peak flow rate). This water quality design flow rate was provided to Modular Wetlands in order for them to size the proposed treatment facilities. Sizing criteria and design of the Modular Wetlands structures is provided in Appendix C.

Peak run-off associated with and up to a 25-year storm event has been determined to be adequate. Uniform flow analysis utilizing Manning's equation, shown below, was employed with a Manning's Roughness Coefficient (n) of 0.012. Manning's equation -Q= IA?( xAxR 2i3xS 112 With: Q = Flow (CFS) n = Manning's Roughness Coefficient (0.012) A = Flow Area (SF) R = Hydraulic Radius= Area /Wetted Perimeter (LF) S = Slope of the pipe (ft/ft) Based on the revised basin areas and existing pipe sizes, the existing conveyance system is adequate for the 25-year storm event. All new conveyance pipes will also be designed to convey the 25-year storm event. Additionally, the overflow from a 100-year storm event will not create or aggravate a severe flooding problem or severe erosion problem. See Appendix C for conveyance design calculations. 100-Year Flood/Overflow Condition Review of the current FEMA FIRM maps (Panels 0978F, 0979 F) indicates that the project site lies within the Zone X, which is determined to be outside of the 100-year flood plain. If the existing storm system were to experience a major storm event, the stormwater detention area would overflow in to the rear access drive, and along the road westerly towards Lind Ave SW. The stormwater system for this project has been designed to address the storm events in accordance with design criteria described previously. In the event of a larger storm, it is unlikely that the system would fail. Based on a review of the site and immediate surroundings, the overflow of the stormwater conveyance system would allow surface water to sheet flow to the public storm system in Lind Avenue.

Coverage under the NPDES Permit. A copy of the Permit Coverage Letter is provided in Appendix F. These permits will require approval by the City of Renton Planning Division or the Department of Ecology. PACLAND Project #10439013 Page 25 Firestone Complete Auto Care Technical Information Report Renton, Washington Section 8-CSWPPP Analysis and Design All erosion and sediment control measures shall be governed by the requirements of the City of Renton and the Washington State Department of Ecology. A temporary erosion and sedimentation control plan will be prepared to assist the contractor in complying with these requirements. The Erosion and Sediment Control (ESC) plan will be included with the construction plans. 1. Erosion Risk Assessment The degree of erosion risk on the proposed project site is minimal. The following factors contribute to a low degree of erosion risk: • Slope across the site is minimal. Runoff will not travel at high velocities across the site and, therefore, will not cause noticeable erosion impacts. • The site consists primarily of impervious surfaces. 2. Construction Sequence and Procedure The proposed development will include an erosion/sedimentation control plan designed to prevent sediment-laden run-off from leaving the site during construction. The erosion potential of the site is influenced by four major factors: soil characteristics, vegetative cover, topography, and climate. Erosion/sedimentation control is achieved by a combination of structural measures, cover measures, and construction practices that are tailored to fit the specific site. Prior to the start of any grading activity upon the site, all erosion control measures, including stabilized construction entrances, shall be installed in accordance with the construction documents. The best construction practice will be employed to properly clear and grade the site and to schedule construction activities. The planned construction sequence for the construction of the site is as follows: 1. Attend a pre-construction meeting with the City of Renton. 2. Install temporary erosion control features. 3. Demolish existing structure(s). 4. Clear and grub expansion area. 5. Grade site. 6. Construct buildings. 7. Pave site and install landscaping. 8. Remove temporary erosion control features once site is fully stabilized. 3. Trapping Sediment PACLAND Project #10439013 Page 26 Firestone Complete Auto Care Technical Information Report Renton, Washington Structural control measures will be used to reduce erosion and retain sediment on the construction site. The control measures will be selected to fit specific site and seasonal conditions. The following structural items will be used to control erosion and sedimentation processes: • Stabilized construction entrances • Filter fabric fences • Catch Basin Inlet Sediment Protection • Proper Cover measures Weekly inspection of the erosion control measures will be required during construction. Any sediment buildup shall be removed and disposed of off-site. A stabilized construction entrance will be installed at the site entrance to avoid vehicle tracking off mud off-site. The entrances are a minimum requirement and may be supplemented if tracking of mud onto public streets becomes excessive. In the event that mud is tracked off site, it shall be swept up and disposed of off site on a daily basis. Depending on the amount of tracked mud, a vehicle road sweeper may be required. Because vegetative cover is the most important form of erosion control, construction practices must adhere to stringent cover requirements. More specifically, the contractor will not be allowed to leave soils open for more than 14 days and, in some cases, immediate seeding will be required. 4. Wet Season TESC Operating Plan Work between October 1'' and April 30'h must adhere to the Wet Season Special Provisions noted in the 2009 KCSWDM.

Therefore, the first year requires inspection monthly during the wet season and every other month during the dry season in order to observe and record the amount of pollutant loading the system is receiving.

Stormwater regulations require that all BMPs be inspected and maintained to ensure they are operating as designed to allow for effective pollutant removal and provide protection to receiving water bodies. It is recommended that inspections be performed multiple times during the first year to assess the site specific loading conditions. This is recommended because pollutant loading and pollutant characteristics can vary greatly from site to site. Variables such as nearby soil erosion or construction sites, winter sanding on roads, amount of daily traffic and land use can increase pollutant loading on the system. The first year of inspections can be used to set inspection and maintenance intervals for subsequent years to ensure appropriate maintenance is provided. Without appropriate maintenance a BMP will exceed its storage capacity which can negatively affect its continued performance in removing and retaining captured pollutants. Inspection Equipment Following is a list of equipment to allow for simple and effective inspection of the MWS Linear: • Modular Wetland Inspection Form • Flashlight • Manhole hook or appropriate tools to remove access hatches and covers • Appropriate traffic control signage and procedures • Measuring pole and/or tape measure. • Protective clothing and eye protection. • 7/16" open or closed ended wrench. • Large permanent black marker (initial inspections only-first year) • Note: entering a confined space requires appropriate safety and certification. It is generally not required for routine inspections of the system. ~I/ www.modularwetlands.com "T" _ . L • __ I T _ { _ ", -I.. MODULAR WETLANDS Inspection Steps The core to any successful stormwater BMP maintenance program is routine inspections. The inspection steps required on the MWS Linear are quick and easy. As mentioned above the first year should be seen as the maintenance interval establishment phase. During the first year more frequent inspections should occur in order to gather loading data and maintenance requirements for that specific site. This information can be used to establish a base for long term inspection and maintenance interval requirements. The MWS Linear can be inspected though visual observation without entry into the system. All necessary pre-inspection steps must be carried out before inspection occurs, especially traffic control and other safety measures to protect the inspector and near-by pedestrians from any dangers associated with an open access hatch or manhole. Once these access covers have been safely opened the inspection process can proceed: • Prepare the inspection form by writing in the necessary information including project name, location, date & time, unit number and other info (see inspection form). • Observe the inside of the system through the access hatches. If minimal light is available and vision into the unit is impaired utilize a flashlight to see inside the system and all of its chambers. • Look for any out of the ordinary obstructions in the inflow pipe, pre-treatment chamber, biofiltration chamber, discharge chamber or outflow pipe. Write down any observations on the inspection form. • Through observation and/or digital photographs estimate the amount of trash, debris and sediment accumulated in the pre-treatment chamber. Utilizing a tape measure or measuring stick estimate the amount of trash, debris and sediment in this chamber. Record this depth on the inspection form. -.modularwetlands.com 1_ MODULAR WETLANDS Inspection Steps The core to any successful storm water BMP maintenance program is routine inspections.

The diagram below illustrates where a li ne should be drawn . This line is a referen ce point for future inspections of the system: , Us ing a permanent marker draw a 6 inch long horizontal line, as s hown, at the ,..~ higher water level in the MWS Linear discharge chamber. • Water level in the discharge chamber is a function of flow rate and pipe size. Observation of water level during the first few months of operation can be used as a benchmark level for future inspections. The initial mark and all future observations shall be made when system is at 100% capacity (water level at maximum level in pre-treatment chamber). If future water levels are below this mark when system is at 100% capacity this is an indicator that maintenance to the pre-filter cartridges may be needed . • Finalize inspection report for analysis by the maintenance manager to determine if maintenance is required. www.modularwetlands.com lL ..

WETLANDS Inspection Notes 1. Following maintenance and/or inspection, it is recommended the maintenance operator prepare a maintenance/inspection record. The record should include any maintenance activities performed, amount and description of debris collected, and condition of the system and its various filter mechanisms. 2. The owner should keep maintenance/inspection record(s) for a minimum of five years from the date of maintenance. These records should be made available to the governing municipality for inspection upon request at any time. 3. Transport all debris, trash, organics and sediments to approved facility for disposal in accordance with local and state requirements. 4. Entry into chambers may require confined space training based on state and local regulations. 5. No fertilizer shall be used in the Biofiltration Chamber. 6. Irrigation should be provided as recommended by manufacturer and/or landscape architect. Amount of irrigation required is dependent on plant species. Some plants may not require irrigation after initial establishment. -.modularwetlands.com MODULAR WETLANDS Inspection Notes 1.

Maintenance Overview WETLANDS The time has come to maintain your Modular Wetland System Linear (MWS Linear). To ensure successful and efficient maintenance on the system we recommend the following. The MWS Linear can be maintained by removing the access hatches over the systems various chambers. All necessary pre-maintenance steps must be carried out before maintenance occurs, especially traffic control and other safety measures to protect the in spector and near-by pedestrians from any dangers associated with an open access hatch or manhole. Once traffic control has been set up per local and state regulations and access covers have been safely opened the maintenance process can begin. It should be noted that some maintenance activities require confined space entry. All confined space requirements must be strictly followed before entry into the system. In addition the following is recommended: • Prepare the maintenance form by writing in the necessary infonnation including project name, location, date & time , unit number and other info (see maintenance form). • Set up all appropriate safety and cleaning equipment. • Ensure traffic control is set up and properly positioned. • Prepare a pre-checks (OSHA, safety, confined space entry) are performed. Maintenance Equipment Following is a li st of equipment required for maintena nce of the MWS Linear: • Modular Wetland Maintenance Form • Manhole hook or appropriate tools to access hatches and covers • Protective clothing, flashlight and eye protection. • 7/16" open or c losed ended wrench. • Vacuum assisted tru ck with pressure washer. • Replacement BioMediaGREEN for Pre-Filter Cartridges if required (order from manufacturer). r::1 -/. di ~ www.modularwetlands.com M ODU L A R W ETLANDS Maintenance Steps 1.

Date: September 23, 2016 Introduction The project proponent is planning to build a new Firestone auto care center on 0.88 acres at 17808 108'h Ave. SE in Renton, WA. The proponent has retained WFCI to: • Evaluate and inventory all trees on the site pursuant to the requirements of the City of Renton Tree Protection Ordinance. • Make recommendations for retention of significant trees, along with required protection and cultural measures. Observations Methodology In accordance with Renton Municipal Code 4-4-130, WFCI has evaluated all significant trees on site. This includes cottonwood and red alder trees 8 inches diameter at breast height (DBH) and larger, and all other trees 6 inches DBH and larger, and assessed their potential to be incorporated into the new project. Trees were numbered on a map, but not marked in the field. The tree evaluation phase used methodology developed by Nelda Matheny and Dr. James Clark in their 1998 publication Trees and Development: A Technical Guide to Preservation of Trees during Land Development. URBAN/RURAL FORESTRY • TREE APPRAISAL • HAZARD TREE ANALYSIS RIGHT-OF-WAYS• VEGETATION MANAGEMENT• ENVIRONMENTAL STUDIES• CONTRACT FORESTERS Member of International Society of Arboriculturs and Society of American Foresters Page 2 -Renton Firestone --Tree Protection Plan Site Description The site has an existing restaurant, with associated parking lot surrounding the building. The eastern portion of the lot includes a grass lawn and trees. There are 26 native and planted trees on site. Overall, tree quality is very poor to fair. The trees on site range between approximately 15 and 40 years old. The site is generally flat, except a short treed slope along the southern boundary exist. Soil Description According to the USDA Web Soil Survey there is one soil type on this parcel (see soils map below). Alderwood gravelly sandy loam, a moderately deep, moderately well drained soil found on glacial till plains. It is formed in ablation till overlying basal till. A weakly cemented hardpan is at a depth of 20 to 40 inches. Permeability is moderately rapid above the hardpan and very slow in the pan. Available water capacity is low. The effective rooting depth for trees is 20-40 inches. A perched seasonal high water table is at a depth of 18-36 inches from November to March. The potential for windthrow of trees is moderate under normal conditions. New trees require irrigation for establishment. In areas where grading brings the hardpan nearer to the surface, the hardpan must be fractured under new trees to provide soil volume for root development and to improve drainage around the tree. Washington Forestry Consultants, Inc. 2 Page 3 -Renton Firestone --Tree Protection Plan Tree Conditions The project area consists of one conifer forest cover type with scattered deciduous trees. An inventory of the trees was conducted to determine the composition and health of the forest. Type I. --The majority of the trees in this type are Scotch pine (Pinus sylvestris). Other species include Sitka spruce (Picea sitchensis), grand fir (Abies grandis), and red alder (A/nus rubra). There is also one Douglas-fir (Pseudotsuga menziesii), one Alaska yellow cedar (Chamaecyparis nootkatensis), and one flowering plum (Prunus spp.). There are a total of 26 significant trees in this type, ranging in diameter from 6 to 26 inches DBH. Seventeen (17) of the trees were classified as sound, healthy, long-term trees in the dominant and co-dominant crown class. The other nine trees are not long-term trees due to structural defects and/or poor health.

Off-Site Impacts There is one 16-inch DBH red alder tree just north of the parcel boundary that is m poor condition. Tree removal on this parcel will not impact this tree. Discussion Potential for Tree Retention There are 9 trees that were evaluated as unhealthy. Therefore 17 significant trees in Type I are available for retention. From the site plan provided, it appears that I tree can be saved. The remaining 25 trees will need to be removed due to construction, and retaining wall installation. The proposed 'save' trees are illustrated on the aerial photo in Attachment #1. A detailed list of all trees ( over 6 inches DBH) by species, DBH, condition, root protection zone (RPZ), save/remove potential, and retention availability is provided in Attachment #3. Washington Forestry Consultants, inc. 3 Page 4 -Renton Firestone --Tree Protection Plan Tree Density Calculations Title 4-4-130 of the Renton Municipal Code requires that a minimum of I 0% of all healthy significant trees in buildable areas be retained on the project in a 'commercial' zone. The following is a summary of the required and planned tree retention: Total Project Area Critical Areas and Buffers Buildablc Area Total Number of Trees on Site Trees Excluded from Retention Calculation: Trees that are Dead, Diseased, or Dangerous Number of Healthy, Significant Trees in Buildable Area: Required Tree Retention ('Protected Trees'): I 0% of healthy significant trees in buildable area: Planned Tree Retention Shortfall of Required Tree Retention 0.88 acres 0 acres 0.88 acres 26 trees 9 trees 17 trees 2 trees I tree 1 tree There are 17 healthy significant trees in the buildable area of the site. At least 2 of these trees need to be retained to meet the I 0% requirement of the City of Renton Code. These trees are considered 'Protected Trees'. The proposed plan retains I tree which is below the minimum retention requirement. Therefore replacement trees will be required for the one 'protected' tree to be removed. The Renton Municipal Code requires that "replacement trees, with at least a two-inch (2") caliper or an evergreen at least six feet (6') tall, shall be planted at a rate of twelve (12) caliper inches of new trees to replace each protected tree removed. See the Tree Retention Worksheet in Attachment #4. Replacement Trees Required Number of Landscaping Trees to Count Toward Replacement Requirement (50% of total requirement) Total Tree Replacement Necessary 6 3 3 Up to fifty percent (50%) of trees required pursuant to RMC 4-4-070, Landscaping, may contribute to replacement trees." Therefore, at least three 2-inch caliper deciduous trees or three 6 ft. tall conifers will need to be planted in addition to the Landscaping requirements.The landscape plan (prepared by others) should incorporate native conifer trees along with deciduous accent and shade trees to provide a mix of color, texture, and size. Washington Forestry Consultants, Inc. 4 Page 5 -Renton Firestone --Tree Protection Plan Recommendations Tree Protection Measures Trees to be saved must be protected during construction by six foot high chain link fencing (Attachment #7), located at the edge of the critical root zone (CRZ). Placards shall be placed on the fencing every 50 feet indicating the words, "NO TRESPASSING -Protected Trees". The individual CRZ are a radius of one foot for each one inch of DBH (6 feet minimum), unless otherwise delineated by WFCI (see Attachment #3). Tree protection fences should be placed around the edge of the critical root zone (CRZ). The fence should be erected after logging but prior to the start of clearing. The fences should be maintained until the start of the landscape installation. There should be no equipment activity (including rototilling) within the critical root zone. No irrigation lines, trenches, or other utilities should be installed within the CRZ. Cuts or fills should impact no more than 20% ofa tree's root system. If topsoil is added to the root zone ofa protected tree, the depth should not exceed 2 inches of a sandy loam or loamy fine sand topsoil and should not cover more than 20% of the root system. If roots are encountered outside the CRZ during construction, they should be cut cleanly with a saw and covered immediately with moist soil. Noxious vegetation within the critical root zone should be removed by hand. If a proposed save-tree must be impacted by grading or fills, then the tree should be re-evaluated by WFCI to determine if the tree can be saved with mitigating measures, or if the tree should be removed. Pruning and Thinning All individual trees to be saved near or within developed areas should have their crowns raised to provide a minimum of 8 feet of ground clearance over sidewalks and landscape areas, 15 feet over parking lots or streets, and at least 10 feet of building clearance. All pruning should be done according to the ANSI A300 standards for Eroper pruning, and be completed by an International Society of Arboriculture Certified Arborist , or be supervised by a Certified Arborist®. Conclusions and Timeline for Activity I. One tree is proposed to be retained on the site in the buildable area. 2. The final, approved tree protection plan map should be included in the construction drawings for bid and construction of the project and should be labeled as such. 3. Contact WFCI to attend pre-job conference and discuss tree protection issues with contractors. WFCI can verify all trees to be saved and/or removed are adequately marked for retention. 4. Complete necessary hazard tree removals and invasive plant removals from the tree protection areas. No equipment should enter the tree protection areas during logging. Washington Forestry Consultants, Inc. 5 Page 6 -Renton Firestone --Tree Protection Plan 5. Install tree protection fences along the 'limits of construction'. The fences should be located at the limits of construction or 5 feet outside of the dripline of the save tree or as otherwise specified by WFCI. Maintain fences throughout construction. 6. Complete clearing of the project. 7. Do not excavate stumps within 10' of trees to be saved. These should be individually evaluated by WFCI to determine the method ofremoval. 8. Complete all necessary pruning on save trees or stand edges to provide at least 8' of ground clearance near sidewalks and trails, and 15' above all driveways or access roads. 9. Complete grading and construction of the project. Summary The City of Renton Municipal Code requires 2 of the 17 significant trees be retained on the buildable area of the site. This plan retains I tree, which is I short of the minimum tree retention requirement. Therefore, at least 6 two inch caliper deciduous trees or 6 six foot tall conifers need to be planted as replacement trees to meet the minimum density requirements. Credit for 3 of these trees can be taken from trees planted as a requirement of the landscaping code. Please give me a call if you have further questions. Respectfully submitted, J!/~>n.L~ Galen M.

Washington Forestry Consultants, Inc. 12 Page 13 -Renton Firestone --Tree Protection Plan Attachment #6: Description of Tree Evaluation Methodology The evaluation of the tree condition on this site included the visual assessment of: l. Live-crown ratio, 2. Lateral and terminal branch grmvth rates, 3. Presence of dieback in minor and major scaffold branches and twigs, 4. Foliage color, 5. Stem soundness and other structural defects, 6. Visual root collar examination, 7. Presence of insect or disease problems. 8. Windfirmness if tree removal will expose this tree to failure. In cases where signs of internal defect or disease were suspected, a core sample was taken to look for stain, decay, and diameter grmvth rates. Also, root collars were exposed to look for the presence of root disease. In all cases, the overall appearance of the tree was considered relative to its ability to add value to either an individual lot or the entire subdivision. Also, the scale of the tree and its proximity to both proposed and existing houses was considered. Lastly, the potential for incorporation into the project design is evaluated, as well as potential site plan modifications that may allow otherwise removed tree(s) to be both saved and protected in the development. Trees that are preserved in a development must be carefully selected to make sure that they can survive construction impacts, adapt to a new environment, and perform well in the landscape. Healthy, vigorous trees arc better able to tolerate impacts such as root injury, changes in soils moisture regimes, and soil compaction than are low vigor trees. Structural characteristics are also important in assessing suitability. Trees with significant decay and other structural defects that cannot be treated are likely to fail. Such trees should not be preserved in areas where damage to people or property could occur. Trees that have developed in a forest stand are adapted to the close, dense conditions found in such stands. When surrounding trees are removed during clearing and grading, the remaining trees are exposed to extremes in wind, temperature, solar radiation, which causes sunscald, and other influences. Young, vigorous trees with well-developed crowns are best able to adapt to these changing site conditions. Washington Forestry Consultants, Inc.

Engineering• Consulting• Testing June 1, 2016 Page 1 o/7 PSI understands the site improvements will consist of a new single story retail facility and expanded parking. Based on preliminary structural information provided and previous experience with similar projects, we anticipate column and wall loads be on the order of 30 kips and 3 kips per foot, respectively. We also anticipate design floor loads of about 125 psi with a maximum concentrated load of 8 kips. 2. SITE DESCRIPTION 2.1. General The proposed site is located at 17808 108th Ave SE in Renton, Washington. Based on readily available aerial images the site presently has a single story building, which we understand will be razed prior to construction. The remainder of the site has sporadic landscaped shrubbery and paved parking. The site is bordered to the west by 108'" Ave SE (State Route 515), to the east by 109'" Ave SE, and to the north and south by existing developments. 2.2. Topography Our review of available topographic information indicates that the proposed site is relatively flat with elevations ranging from approximately EL400 to EL410 from east to west over a distance of approximately 300 feet, based on available aerial imagery on Google Earth. 2.3. Geology Based on a review of the geology of the region utilizing the Washington Department of Natural Recourses Interactive Geologic Map (WDNRIGM), PSI observed that this area is mapped as Quaternary glacial till. Glacial till is typically silts sand and gravels that have been overridden by a glacier and are thereby heavily over-consolidated. 2.4. Seismic Design Values The nearest mapped fault zone to the site is the Seattle Fault Zone approximately 5 miles northwest of the site. The Seattle Fault Zone is mapped as a Holocene age thrust faults that trend east to west with a reported slip rate of 0.2 to 1 mm per year (Reference 2). The contribution of potential earthquake-induced ground motion from known sources is included in the probabilistic ground motion maps published by the USGS. Design data regarding seismic site characterization and design recommendations based on USGS mapping and analysis are implemented in the 2012 International Building Code. Based on the SPT data collected during our drilling, the site conforms to the characteristics of Site Class C. The published design ground motion values, based on the USGS Seismic Design Maps (Reference 3), corresponding to a risk-targeted 2 percent probability of exceedance in 50 years at the project site. Seismic design values for the project site are provided in Table 1 below.

Subsurface conditions Subsurface materials and conditions were investigated with nine hollow-stem auger borings performed on May 16"', 2016. The nine borings were drilled to a depth of approximately 11 to 21 feet below the ground surface. The approximate locations of the soil borings are shown on Figure 2. In general, the soils under the proposed building areas generally consist of loose to medium dense silty sands fill soils over medium dense to very dense glacial till soils. A description of our field investigation, and our boring logs, are available in Appendix A. A description of the laboratory testing program along with sample test results are available in Appendix B. The terms used to describe material encountered in the boring are defined in the General Notes. A description of the soils as they were encountered from the ground surface is provided below. 1. FILL: The fill generally consisted of silty sands. The fill was observed in all borings. N-Values in the silty sand fill soils ranged from 3 to 25 blows per foot to indicate relative densities of loose to medium dense. Moisture contents of the fill soils range from 15 percent to 20 percent. 2. WEATHERED TILL: The weathered till deposits consisted of light brown to dark brown with orange mottling, silty sand and silt with sand soils. Weathered till was observed in all borings. N-Values ranged from 22 to 72 blows per foot in the silty sand soils to indicate relative densities of medium dense to very dense. Moisture contents in the silty sand soils range from 13 percent to 18 percent. 3. TILL: The till deposits consisted of gray silty sand soils and were observed in all borings except B-1 and B-2. N-Values ranged from 50 blows for 2 inches to 50 blows for 6 inches to indicate a relative density of very dense. Moisture contents of the till range from 9 percent to 20 percent. 2.6. Groundwater Static groundwater was not encountered at the boring locations at the time of our field investigation; however, PSI believes that small amounts of perched water was observed in borings B-3 and B-4. This perched water was observed within sand lenses within the till soils and may be present in other portions of the site seasonally or after significant precipitation events. 3. CONCLUSIONS AND RECOMMENDATIONS 3.1. General Subsurface explorations for this investigation indicate the presence of as much as 3Y, to 5Y, feet of fill overlying glacially consolidated soils across the entire site. It is PSl's opinion that the onsite soils are suitable to support conventional spread footings provided the recommendations stated below are followed. Firestone Retail Store 17808 1081h Ave SE, Renton, Washinu . PSI Project l\'o 07121375 3.2. Site Preparation Professional Service Industries, Inc. Engineering • Consulting• Testing .June I, 2016 Page 3 ofl We anticipate that the removal of existing structures, foundations and utilities will likely disturb the upper 3y, to SY, feet of soils in the northern portion of the site. Any large debris encountered below proposed new buildings should be removed. 3.3. Structural Fill All fill placed beneath foundation elements, sidewalk, and pavement areas should be placed as compacted structural fill. We recommend that structural fill extends at least 2 feet beyond building and pavement limits where nearby structures do not restrict fill placement. On-site soils, in lieu of organic matters or other deleterious materials can be reused for backfill purposes, provided the material can obtain moisture contents that will allow it to meet compaction requirements. Imported material, if required, should be approved by the geotechnical engineer. Compacted fill should be placed in 12-inch-thick lifts (loose) by heavy compactors such as large vibratory rollers and hoe-packs and in 6 inch loose lists for smaller compactors such as small plate compactors and jumping jacks. These soil should be moisture-conditioned to wi1hin 2 percent of the optimum moisture content, and compacted to a density of 95% of the maximum dry density as determined by ASTM D 1557. The condition of the subgrade should be evaluated by a PSI representative before fill placement or construction begins. Fill compaction should be evaluated by in-place density tests performed during fill placement so that adequacy of soil compaction efforts may be evaluated as earthwork progresses. When fill material is inconsistent or when more than 30% of the fill material is retained on a 'Y. inch sieve, fill placement should be observed and compaction evaluated by observation of a proof-roll using a loaded tandem axle dump truck. If Imported fill materials area required PSI recommends they consist of granular material such as pit-run or quarry-run rock, crushed rock, crushed gravel, or sand. They should be fairly well-graded between coarse and fine material with a maximum particle size of 2 inches and should have less than 5 percent by weight passing the U.S. Standard No. 200 Sieve. 3.4. Utility Trench Excavations and Backfill Excavations should be made in accordance with applicable Federal and State Occupational Safety and Health Administration regulations. Utility trenches in the near surface sand soils at the site will need to be sloped, or shored from the ground surface due to the potential for caving. Actual inclinations will ultimately depend on the soil conditions encountered during earthwork. While we may provide certain approaches for trench excavations, the contractor should be responsible for selecting the excavation technique, monitoring the trench excavations for safety, and providing shoring, as required, to protect personnel and adjacent improvements. The information provided below is for use by the owner and engineer and should not be interpreted to mean that PSI is assuming responsibility for the contractor's actions or site safety. The fill and soft silty soils PSI encountered onsite should be considered Type C soils. Dense or hard native soils can be classified as Type B soil according to the most recent OSHA regulations. In our opinion, excavations should be safely sloped or shored. The contractor should be aware that excavation and shoring should conform to the requirements specified in the applicable local, state, and federal safety regulations, such as OSHA Health and Safety Standards for Excavations, 29 CFR Part 1926, or successor regulations. We understand that such regulations are being strictly enforced, and if not followed, the contractor may be liable for substantial penalties. FireMone Retail Store J 7808 108'h Ave SE, Renton. Washin,., _ 1 PSI Project No 07121375 Professional Service Industries, Inc. t:ngineering • Consulting • Testing June I, 2016 Page 4 of7 Excavation and construction operations may expose the on-site soils to inclement weather conditions. The stability of exposed soils may deteriorate due to a change in moisture content or the action of heavy or repeated construction traffic. Accordingly, foundation and pavement area excavations should be protected from the elements and from the action of repetitive or heavy construction loadings. Utilities trenches within the building, pavement, and sidewalk areas should be backfilled with structural fill and compacted in accordance with the recommendation in section 3.3 of this report with the exception of fill soils placed immediately around and above the first foot vertically around utility lines which should be compacted to at least 90% of the maximum dry density as determined by ASTM D 1557. Compaction by jetting or flooding should not be permitted. 3.5. Foundations PSI has provided two options for the potential foundation subgrade preparation which are listed below. Option 1: Footing subgrades should be over-excavated a minimum of two feet and have the soil in the base of the trenches compacted to a firm and unyielding state as determined by the geotechnical engineer, then the removed soil should either be recompacted as structural fill back into the over-excavated area or should replaced with imported structural fill, place in accordance with the recommendations in Section 3.3 of this report. The over-excavation and backfill areas should extend at least 2 feet beyond the edge of the footings or a distance equivalent to the dlepth of the over-excavation, whichever is greater. Provided these foundation subgrades are prepared in this way the building may be supported by shallow spread footings with an allowable bearing pressure of up to 3,000 pounds per square foot (psi). This value applies to the total of dead load and/or frequently applied live load and can be increased by one-third for the total of all loads; dead, live and wind or seismic. Option 2: Footing may be excavated extending to dense native glacial till soils that were observed from 3Y:z to 5Y:z feet below existing site grades. Footings extending down to these dense native soils may be designed with an allowable bearing capacity of 5,000 psf. This value applies to the total of dead load and/or frequently applied live load and can be increased by one-third for the total of all loads; dead, live and wind or seismic. Regardless of the option selected All footings should have a minimum 18 inches of embedment below the lowest adjacent final grade for frost protection and all footing subgrades should be prepared in the same manner across the site. Perimeter and spread footing should be at least 18 inches and 24 inches wide respectively. Horizontal forces can be resisted partially or completely by frictional forces developed between the base of the spread footings. The total shearing resistance between the foundation footprint and the soil should be taken as the normal force, i.e., the sum of all vertical forces (dead load plus real live load) times the coefficient of friction between the soil and the base of the footing. We recommend assuming an ultimate coefficient of friction value of 0.30 for design. If additional lateral resistance is required, passive earth pressures against embedded footings or walls can be computed using a pressure based on an equivalent fluid with a unit weight of 250 pounds per cubic foot. This value assumes that backfill around footings will be placed as granular structural fill. Firestone Retail Store 17808 1081h Ave SE, Renton, Washin" PSI Project So 0712 I 375 3.6. Settlement Professional Service Industries, Inc. Engineering • Consulting • Testing June I, 2016 Page 5 of7 The building foundation loads, and floor live loads will all cause settlement due to consolidation, or compression, of the underlying soils. The subsurface information and laboratory test data developed for this study was used to estimate settlement beneath these loads. We have assumed that the maximum wall and column loads will be 3 kips per foot and 30 kips for the purpose of this analyses on both foundation options. We estimate that the settlement of a typically loaded, isolated column footing designed in a=rdance with our previously recommended allowable bearing pressure of 5,000 psf on dense native soil will be less than 1 inch, additionally we estimate that settlement for 3,000 psf footings, founded on 2 feet of structural fill, will be less than 1 inch. These estimates assume that the load on the footings are real dead load and sustained or long- term live load. Lesser actual bearing pressures will produce less settlement. Some differential settlement between footings should be expected due to differences in their size and loading conditions and the variability in subsurface conditions across the building footprint. Differential settlements are difficult to quantify; however, we anticipate they will likely be limited to less than about one half of the total settlement or less than Y, inch for both foundation options along a 40-foot span. Settlement of the footings is also expected to occur rapidly, essentially as the new structural loads are placed and shortly thereafter. Footing settlements will be in addition to areal settlements due to floor live, or storage loads. For this reason. we recommend that floors, walls and columns be designed to move independently of each other. 3.7. Floor Support PSI recommends that soil subgrades below the slab be compacted to a firm and unyielding state. Compaction of in these areas should be confirmed with a proof rolled with a loaded tandem axe! dump truck, or be observed by the geotechnical engineer or their representative to be firm and unyielding. We further recommend the installation of a 6-inch thick granular base course beneath the floor slab to provide uniform support and a capillary break between the slab and the subgrade soil. The base course should consist of crushed rock with particles no larger than 1-inch size and having less than about 2% passing the No. 200 sieve (washed analysis). Crushed rock o/.i to Y. inch gradation is often used for this purpose. The base course material should be installed in a single lift and compacted to at least 95% of the maximum density as determined by ASTM D 1557 or to a firm and unyielding state. In our opinion, it is appropriate to assume a coefficient of subgrade reaction, k, of 250 pound per cubic inch for the design of floor slabs constructed as recommended above. It may also be appropriate to install a vapor-retarding membrane beneath slabs that will receive floor coverings or will be used to store moisture-sensitive materials. The membrane should be installed in accordance with manufacturer's recommendations. 3.8. Drainage We recommend footing drains be placed around the exterior of the building foundation to reduce the potential for lateral migration of moisture into the building envelope. We recommend that all roof drains be connected to a tight-line pipe leading to storm drain facilities. Pavement surfaces and open space areas should be sloped such that surface water runoff is collected and routed to suitable discharge points. We also recommend that ground surfaces adjacent to buildings be sloped to facilitate positive drainage away from the buildings. 3.9. Pavement For automobile parking areas founded on silty sand fill soil, we recommend a pavement section consisting of 2Y, inches of asphaltic concrete (AC) over 4 inches of crushed rock base (CRB) or 4 inches of Portland Cement Concrete (PCC) over 4 inches of crushed rock base. If semi-trucks, or other heavy equipment is Firestone Retail Store 17808 JOS'h Ave SE. Renton. Washin,r.1 PSI Project .\'o 0712 l 3 75 Profe:,;sional Service Industries, Inc. Engineering• Consulting• Testing June 1, 2016 Page 6 of7 expected on paved areas, the pavement section should consist of 4 inches of AC over 6 inches of CRB or 5 inches of PCC over 6 inches of CRB. These preliminary pavement sections are based on a pavement design using the site sand subgrade, a desired pavement life of 20 years, and a terminal serviceability index of 2.0. These estimates should be revised once design traffic information is developed. These recommended pavement sections are also based on the assumption that the subgrade consists of firm, undisturbed soil or structural fill and that the pavement will be constructed during the dry summer months. Proofrolling should be used to evaluate pavement subgrade. Any soft areas disclosed by proofrolling will likely require over-excavation and replacement with structural fill. Some contingency should be provided for the repair of any soft areas. Permanent, properly installed drainage is also an essential aspect of pavement design and construction. All paved areas should have positive drainage to prevent ponding of surface water and saturation of the base course. This is particularly important in cut sections or at low points within the paved areas, such as in sunken loading dock areas or around stormwater catch basins. Effective means to prevent saturation of the base course induding installing subdrain systems below sunken loading docks and weep holes in the sidewalls to catch basins. 3.10. Stormwater Based on previous experience on glacial till sites PSI does not believe that infiltration of site stormwater will be practical. Glacial till soil in this region typically provide infiltration rates of less than one inch per hour and very often less than % inch per hour. 4. DESIGN REVIEW AND CONSTRUCTION MONITORING We welcome the opportunity to review and discuss construction plans and specifications as they are being developed. We are of the opinion that to observe compliance with the design concepts, specifications, and recommendations, construction operations dealing with earthwork and foundations should be observed by a qualified geotechnical engineer. We would be pleased to provide these services to you. 5. REPORT LIMITATIONS The recommendations submitted in this report are based on the subsurface information obtained by PSI and design details furnished by representatives of the client, Bridgestone Retail Operations LLC., for the proposed improvements at 17808 1 OB"' Avenue SE in Renton, Washington. If there are any revisions to the plans for this project, or if deviations from the subsurface conditions noted in this report are encountered during construction, PSI should be notified immediately to determine if changes in the foundation and/or pavement recommendations are required. If PSI is not retained to review these changes, PSI will not be responsible for the impact of those conditions on the project. After the plans and specifications are more complete, PSI should be retained and provided the opportunity to review the final design plans and specifications to verify that our engineering recommendations have been properly incorporated into the design.

Engineering• Consulting• Testing June/, 2016 FIELD EXPLORATION PROGRAM General We explored the site by drilling nine soil borings (B-1 to B-9) to depths that ranged from approximately 11 feet to 21 feet below existing ground surface on May 16, 2016, using a trailer- mounted mobile drill rig. The locations of the borings are shown on Figure 2. A representative of PSl's geotechnical staff was present during the explorations to record soil and groundwater conditions encountered in the exploration and to obtain soil and rock samples for laboratory testing. Sampling Procedures Throughout the drilling operation, soil samples were obtained from the borings using a 2-inch OD Split Spoon in general conformance with guidelines presented in ASTM 01586, Standard Test Method for Penetration Test and Split Barrel Sampling of Soils. The samplers were driven into the soil a distance of 18 inches or to refusal with a 140-pound hammer free falling a distance of 30 inches. The sum of the blows required to drive the sampler in three 6-inch increments is provided in the boring logs. If the sampler met refusal, the number of inches driven and the number of blows is recorded. The borings were drilled to observe the stratigraphy, density, and variability of subsurface soil conditions. Soil samples recovered from the explorations were sealed in airtight plastic bags to retain moisture and carefully transported to PSl's laboratory for additional examination and testing. Field Classification Soil samples were initially classified visually in the field. Consistency, color, relative moisture, degree of plasticity, peculiar odors and other distinguishing characteristics of the soil samples were noted. The terminology used in the soil and rock classifications and other modifiers are defined in the General Notes in this appendix. Exploration Logs Summary boring logs follows in this appendix. The left-hand portion of the boring log gives our interpretation of the soil encountered in the soil boring, sample locations and depths, and groundwater information. The right-hand portion of the log shows the results of the sample water contents, and other laboratory information. The soil profile shown on the boring logs represent the conditions only at actual exploration location. Variations may occur and should be expected. The stratifications represent the approximate boundary between subsurface materials; the actual transition may be gradual. ~., ,~ GENERAL NOTES SAMPLE IDENTIFICATION The Unified Soil Classification System (USCS), AASHTO 1988 and ASTM designations 02487 and D-2488 are used to identify the encountered materials unless otherwise noted. Coarse-grained soils are defined as having more than 50% of their dry weight retained on a #200 sieve (0.075mm); they are described as: boulders, cobbles, gravel or sand. Fine-grained soils have less than 50% of their dry weight retained on a #200 sieve; they are defined as silts or clay depending on their Atterberg Limit attributes.

Engineering • Consulting• Testing June l, 2016 Firestone Retail Store 17808 1081h Ave SE. Renton, Washmglon PSI Project No 07121 375 Professional Service Industries, Inc. Engineering• Consulting • Testing June I, 2016 Laboratory Testing Program and Procedures General Soil samples obtained during the field explorations were examined in our laboratory. The physical characteristics of the samples were noted and the field classifications were modified where necessary in accordance with terminology presented the General Notes included in this appendix. Representative samples were selected during the course of the examination for further testing. The testing procedures and results of the tests are summarized below. The phrase "In general accordance with guidelines presented in .. ." means that certain local and common descriptive practices and methodologies have been followed. Visual-Manual Classification The soil samples were classified in general accordance with guidelines presented in ASTM 02488, Standard Practice for Description and Identification of Soils (Visual-Manual Procedure). Certain terminology incorporating current local engineering practice, as provided in the Soil Classification Chart included with or in lieu of ASTM terminology. The term which best described the major portion of the sample was used in determining the soil type (that is, gravel, sand, silt or clay). Moisture Content Natural moisture content determinations were made on all samples. The natural moisture content is defined as the ratio of the weight of water to dry weight of soil, expressed as a percentage. The results of the moisture content determinations are presented on the boring logs in this appendix. Grain-Size Distribution Select samples from the borings were analyzed for grain size in general conformance with ASTM C 136 and ASTM C117. In general, samples were oven dried, weighed then washed over a #200 sieve to remove silt and clay sized particles and then dried again. The samples were separated through a series of sieves of progressively smaller openings for determination of particle size distribution. The material passing and/or retained on each sieve was recorded as a percent of the total sample weight. The results of the sieve analysis are depicted in this appendix.

The western approximately 4/5'h of the property is developed with a 2,200 square foot single-story building, occupied by a Skipper's Seafood, with a surrounding parking lot. The eastern portion of the property is at a slightly higher elevation and consists of a tended grass lot with scattered trees and a fence on its western edge dividing the developed portion of the parcel from the green space. The site is bordered to the north and south by developed commercial properties; to the east by 109th Avenue SE and developed residential properties beyond; and to the west by 108'h Avenue SE and developed commercial properties beyond. Topographically, the ground surface on the site generally slopes gently downward to the west with a total vertical relief from the east property boundary to the west of about 10 feet. 19023 36'" Avenue West, Suite D Lynnwood, Washington 98036 ( 425) 582-9928 Zipper Geo Associates, LLC Summary of Field Infiltration Testing Project No. 1688.01 29 August 2016 PROJECT DESCRIPTION A plan provided for our review indicates that proposed development will include one building with paved parking and vehicle access areas. ZGA was not provided with plans for the infiltration facility. You have indicated that the infiltration facility may be approximately 8 feet below existing grade and located north of the proposed building location below parking areas. A proposed location for infiltration testing was outlined on Geotech RFP Exhibit 1.0, issued on 26 July 2016. The test location was moved to the eastern portion of the parcel when it was determined that the Skipper's facility was still in operation and that the initial test location would impede parking and require resurfacing. The project site is illustrated on Figure 1. SCOPE OF SERVICES The purpose of the limited geotechnical engineering services described in this letter was to determine a field-measured stromwater infiltration rate at the site by completing one field infiltration test. Our scope of services included the following: reviewing the King County 2009 Surface Water Design Manual (Manual) regarding stormwater infiltration testing requirements, arranging for marking of underground utilities, completion of one infiltration test, and preparation of this report. Our scope of services did not include addressing other geotechnical engineering aspects of the proposed site improvements. SUBSURFACE CONDITIONS Soil Conditions Published geologic maps indicate that the property is underlain by glacial till. A geotechnical report was previously completed at the site by PSI (Geotechnical Engineering Report, Firestone Retail Store, 17808 108"' Ave. SE, Renton, WA) dated June 1, 2016. Borings completed at the site as part of the PSI report indicate the site is generally underlain by a thin layer of asphalt concrete pavement underlain by about 3.5 to 5 feet of fill consisting of very loose to medium dense, silty sand. Below the silty sand fill, the boring logs disclosed medium dense grading to very dense silty sand with variable gravel content (weathered glacial till grading to unweathered glacial till). Our infiltration test was completed in a test pit located in the eastern, undeveloped portion of the site at the location shown on the attached Figure 1, Site and Exploration Plan. A descriptive Jog of the subsurface conditions observed at the infiltration test location is presented in Appendix A as test pit TP-1. Please note that per the Manual requirements, the soil descriptions are provided in accordance with US Department of Agriculture nomenclature. Soils observed at the infiltration test location included approximately 4 feet of weathered glacial till material consisting of medium dense, light brown to tan with some oxidation, sandy loam with gravel and some organics in the form of tree roots. The weathered till was underlain by unweathered glacial till consisting of dense, tan to light brown, sandy loam with gravel. The test pit was terminated at a depth of approximately 8 feet in dense, tan, unweathered glacial till. 19023 36th Avenue West, Suite D Lynnwood, Washington 98036 Page 2 (425) 582-9928 Zipper Geo Associates. LLC Summary of Field Infiltration Testing Project No. 1688.01 29 August 2016 Groundwater Conditions No groundwater was observed during our exploration, which extended to a depth of approximately 8 feet below existing site grade at the infiltration test location. We did not observe soil coloration mottling suggesting that seasonal groundwater may be higher than the observed condition. PSI did not report observing groundwater in their explorations, which were advanced to a depth of up to 21 feet below the current grade of the paved portion of the property. However, PSI notes that " ... PSI believes that small amounts of perched water was observed in borings B-3 and B-4. This perched water was observed within sand lenses within the till soils and may be present in other portions of the site seasonally or after significant precipitation events." Groundwater conditions should be expected to fluctuate due to seasonal precipitation variation, irrigation, site utilization, and other factors. INFILTRATION TESTING RESULTS A single small-scale Pilot Infiltration Test (PIT) was completed at a depth of approximately 8 feet below existing site grade in general accordance with the procedures described in the Manual. The approximate test location is illustrated on Figure 1. Based on the results of our testing, the field-measured infiltration rate was determined to be approximately 0.21 inches per hour. For design, corrections (or reductions) to the measured infiltration rate should be made for testing, geometry, and plugging per the Manual to arrive at a design infiltration rate.

Approximate exploration locations are shown on the Site and Exploration Plan, Figure 1. Exploration locations were determined by measuring distances from existing site features with a fiberglass tape relative to an ALTA survey CAD file of the site provided PACLAND. As such, the exploration locations should be considered accurate to the degree implied by the measurement method. The approximate ground surface elevation at each exploration location was determined by interpolating the information provided on the ALTA survey. The following sections describe our procedures associated with the exploration. Descriptive logs of the explorations are enclosed in this appendix. Test Pit Explorations An independent contractor working under subcontract to our firm excavated the test pits through the use of a rubber-tired backhoe. An engineering geologist form our firm continuously observed the test pit excavations and logged the subsurface conditions. After we logged each test pit, the operator backfilled each with excavated soils tamped into place. Some settlement of the backfill should be expected over time. The enclosed test pit logs indicate the vertical sequence of soils and materials encountered in each test pit, based primarily on our field classifications and supported by our subsequent laboratory testing. Where a soil contact was observed to be gradational or undulating, our logs indicate the average contact depth. We estimated the relative density and consistency of in situ soils by means of the excavation characteristics and by the sidewall stability. Our logs also indicate the approximate depths of any sidewall caving or groundwater seepage observed in the test pits, as well as all sample numbers and sampling locations.
