The airport is located in Renton's industrial-medium zone, and the project site is 7.84 acres. The overall airport site is 167.3 acres. No changes to existing structures will be made. The project is broken into two phases. The first phase is exempt from the special grade-and-fill pennit per 24 Renton Municipal Code (RMC) 4-9-080©(6). However, phase 2 does require a special grade-and- fill pennit. Additionally, a shoreline exemption is required because an area ofthe project is located in the Shoreline High Intensity Designation along the Cedar River (reach A). The closest point of work 25 for the project is approximately 64ft from the flood wall of the river. The flood wall is estimated to 26 be the ordinary high water mark for the area.

Overall, phase 2 requires 6,700 cubic yards of gravel, import borrow material, top soil, and new asphalt. The project increases the impervious surface area by 8/10 of one percent over the existing 234,700 sq ft of impervious surface. Phase 2 includes new storm drainage, pavement, taxiway edge lighting, striping, directional safety signage, and a water main replacement. According to Ms. Dolbee, on November 19, 2012, an environmental review produced a determination of non-significance with two mitigation measures. A 14-day appeal period commenced on November 19 th , and no appeals were filed. No members of the public or agencies commented on the project. According to Renton Code, the hearing examiner needs to consider the traffic volumes and patterns that will be affected by the project. Construction will occur Monday through Friday from 7am-6pm. Hauling routes will occur from Airport Way S to Rainier Avenue. The applicant indicated that the number and frequency of vehicle trips would not significantly affect public streets. There are no screening or fencing requirements in the city's development standards for this site, but the airport does already have a fence. The project will comply with all FAA regulations. Dust control will be provided during construction through the use of water or other methods as approved by the King County Water Surface Manual. Noise levels due to construction will not rise above noises heard at the airport on a regular basis, and the completed project will not raise noise levels from their current state. The applicant submitted a surface water report for both phases of the project which were prepared by Reid Middleton. An upgraded surface water management facility is included as part of the project. Stormwater discharge will continue to flow towards the Cedar River. The permit is a one-time, project-specific permit for a limited period. Staff recommends approval of the permit. All best management recommendations will be made during the building permit process. Jonathan Wilson, Assistant Airport Manager, testified that he is project manager for the construction. He thanked city staff for preparing the detailed report on the project. In response to questions from the Examiner, Kurt Addicott, Reid Middleton Engineer Inc., stated that a significant amount of asphalt and rock will be hauled for this project. One truck brings in roughly 30-40 cubic yards of material. The total amount of material for the project is 6,700 cubic yards (approximately 200 truck loads). The haul route goes up Rainier A venue to reach the north entrance of the airport. Rainier Avenue hosts primarily businesses, but there are some residences along the northern part of the road. The project managers anticipate construction lasting 63 days. Truck hauling will occur throughout this entire period. The Cedar River water quality will not be decreased due to runoff associated with the project. Ms. Dolbee noted that the construction hours in the application were proposed by the applicant, but these hours comply with Renton Code. The zoning along Rainier Avenue and Airport Way is commercial arterial zoning, typically. There are a few multi-family residences in the vicinity, however. Kayren Kittrick, Development Services Supervisor, added that the haul routes and any traffic control plans will be approved prior to the issue of construction permits. The proposed construction hours are within Renton's construction hour limits. During the permit process, the Community and Economic Development Department has the ability to limit construction hours.

The following exhibit was admitted during the hearing: Exhibit 16: Staff power point. FINDINGS OF FACT I. Applicant. Renton Municipal Airport. 10 2. Hearing. A hearing was held on December 18, 2012 at I :00 pm at the Renton City Hall City Council Meeting Chambers. II 12 13 14 15 16 17 18 19 Substantive: 3. Description of Proposal. The Applicant is requesting a special grade and fill permit for a rehabilitation of 341,065 square feet of Taxiway B, located at the Renton Municipal Airport, 616 West Perimeter Road; zoned Industrial Medium (1M) and located in the High Intensity Shoreline Overlay. The rehabilitation project is divided into two phases; Phase I consists of rehabilitation of the north portion of Taxiway B which is exempt from a special grade and fill permit. Pursuant to RMC 4-9-080(C)(6). Phase 2 would rehabilitate the south end of Taxiway B and is required to obtain a special grade and fill permit, which is included in the application. Both Phase I and 2 would include new storm drainage, pavement, striping, directional safety signage and taxiway edge lighting. Phase 2 would also include a replacement of a water main. Both a Geotechnical Report and a Stormwater Report were submitted with the application. The Renton Municipal Airport is 167.38 acres, however the specific project area is approximately 20 7.84 acres for both Phase I and 2 of the taxiway rehabilitation. 21 22 23 24 25 26 The overall project consists of four parts, taxiway rehabilitation/reconstruction, storm drain lines and hydrant water lines rehabilitation, taxiway designation system modifications, and taxiway edge lighting modifications. a. Taxiway RehabilitationlReconstruction: Rehabilitation of the existing east side taxiway system pavements, including the taxiway connections to the runway from Taxiway 'N' at the north and to the south connection at Runway 34. It is anticipated that the pavement rehabilitation/reconstruction could employ various partial depth or full depth reconstruction methods including hot mix asphalt SPECIAL GRADEIFILL PERMIT - 3 1 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 b. c. d. section reconstruction, reconstruction utilizing Portland Cement Concrete, and milling of the existing asphalt pavement surface followed by re-paving of new asphalt surface. Storm Drain Lines and Hydrant Water Line Rehabilitation: This would include replacing several failing concrete storm drain lines with ductile iron that cross Taxiway B and K. A portion of an existing water line in the vicinity of the south end of the project site would be evaluated for likely replacement as part of Phase 2. Surface grades and associated drainage efficiency within turf infield areas between Taxiway B and Runway 34 will be evaluated. These areas may require re-grading to alleviate existing stormwater ponding issues. New drainage structures would be constructed to facilitate capture of stormwater from re- contoured pavement and turf areas. Taxiway Designation System Modifications: A new taxiway designation system would be developed and the existing airfield signage system would be modified as necessary to reflect the new designations. The existing designations that include designators such as G, H, N, etc., are proposed to be changed to AI, A2, BI, B2 etc. This change would result in a need for new signage, including sign hardware and concrete foundations. Taxiway Edge Lighting Modifications: Taxiway edge lighting is proposed to be adjusted or replaced as necessary to be compatible with new pavement surfaces that result from the taxiway rehabilitation /reconstruction. 4. Surrounding Area. The subject site is bordered: on the north by Lake Washington, on the east by the Cedar River, and to the south and west primarily by commercial development. 5. Adverse Impacts. There are no significant adverse impacts associated with the proposal. Pertinent impacts are addressed in more detail below: Noise. The greatest issue of concern is noise. As testified by the project engineer, the proposal will involve over 200 trucks carrying fill over a 63 day period. Part of the truck haul route will involve areas with multi-family housing along Rainier Avenue and Airport Way. Haul hours are limited by the MDNS between 8:30 am and 3:30 pm Monday through Friday unless otherwise approved by the Development Services Division. Construction hours overall are limited by the MDNS to 7:00 am to 8:00 pm, Monday through Friday and 9:00 am and 8:00 pm on Saturdays. City staff testified that the haul route and noise impacts will be evaluated and addressed during administrative permit review of the proposal. The conditions of approval will impose a noise monitoring program to ensure that noise mitigation measures adequately protect City residents from construction noise impacts. Drainage. Stormwater impacts will be negligible and are fully addressed by the City's stormwater 26 regulations and the Applicant's drainage control plan and TIR., Ex. 7 and II. Phase 2 would SPECIAL GRADE/FILL PERMIT - 4 I 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 result in an increase in impervious surface coverage by eight-tenths of one percent over the existing 234,700 square feet of existing impervious surface area. The Applicant has proposed to upgrade the existing surface water drainage facilities with a combination of wet biofiltration swales, filter strips, catch basins, DIP, and high-density polyethylene (HOPE) pipe. The provided TIR has indicated that along the eastern side of the taxiway crown, surface water would typically be collected and conveyed through catch basins and sent to the western side of the taxiway, within the grass infield area. These concentrated flows would be discharged into a flow splitter device for water quality measures. Water quality for the concentrated flows would be conveyed through a wet biofiltration swale. The TIR identifies that the swale would be designed to meet the King County Service Water Design Manual (KCSWDM) basic treatment criterion of removing 80 percent of the total suspended solids. After leaving the biofiltration swale the stormwater is proposed to be collected in a catch basin and diverted toward the east through a series of surface wllter facilities and finally discharge to the Cedar River. The TIR describes the stormwater proposal for the western side of the taxiway crown as all nonconcentrated flows which would be treated by filter strips, which would then be conveyed to catch basins where the water would combine with the treated flow from the wet biofiltattion swale. Overall the project would not change the stormwater discharge locations as it currently exists today. Section 2 of the TIR identifies that the project would use Best Management Practices (BMPs) for flow control and would install such measure in accordance with the requirements of the KCSWDM. Furthermore a Stormwater Pollution Prevention Plan (SWPPP) for the construction activities would be developed as a part of the overall project. Dust. In the Technical Information Report (TIR) it is identified that the contractor shall control dust to prevent sediment transport from exposed, dry surfaces to the adjacent waterways. It is anticipated that the Contractor would use water for dust control; however the KCSWDM permits the use of other methods to control dust. Critical Areas. There are no critical areas on site. The project is within 200 feet of the Cedar River but is exempt from requiring a shoreline substantial development permit. Screening and Landscaping. No screening or fencing is required by the City of Renton Development Standards for the Airport Use. However, the Airport currently maintains a perimeter fence and ground cover landscaping in any area not covered by impervious surfaces. Airport operations and regulations are determined by the Federal Aviation Administration (FAA), which includes recommendation on Building Restriction Lines (BRL) i.e. Setbacks. Pursuant to the FAA Advisory Circular/150_5300_13a BRL should be set beyond the Runway Protection zones, the Object Free Zones, the Object Free Areas, the runway visibility zone, etc... The project would comply with all FAA regulations. The closest point of work to the Ordinary High Water Mark (OHWM) of the Cedar River is 64 feet from the flood wall (which is estimated to be the approximate location of the OHWM). Approximately 430 feet of the north end of Taxiway B lies within the 200 foot Shoreline SPECIAL GRADE/FILL PERMIT - 5 J 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Jurisdiction. Under current conditions the taxiway functions effectively with the existing fencing, landscaping and setbacks. The rehabilitation project would not result in any changes to the existing screening, landscaping, fencing and setback conditions at the subject site. Conclusions of Law Procedural: 1. Authoritv of Hearing Examiner. RMC 4-9-080(F)(J)(a) provides that the hearing examiner is responsible for granting special permits for fill and grade for grading and/or excavation involving more than 500 cubic yards of minerals or materials. Phase 2 of the proposal involves more than 500 cubic yards of grading and excavation. Substantive: 2. Applicable Standards. RMC 4-9-080(F)( 4) governs the criteria for special fill/grade permits. Applicable criteria are quoted below in italics and applied through corresponding conclusions of law. RMC 4-9-080(F)(4): To grant a special permit, the Hearing Examiner shall make a determination that.. the proposed activity would not be unreasonably detrimental to the surrounding area. The Hearing Examiner shall consider, but is not limited to, the following: 3. i. Size and location of the activity. ii. Traffic volume and patterns. iii. Screening, landscaping, fencing and setbacks. iv. Unsightliness, noise and dust. v. Surface drainage. vi. The length of time the application of an existing operation has to comply with nonsafety provisions of this Title. As determined in Finding of Fact No.5, there are no significant adverse impacts associated with the proposal, which would include unreasonably detrimental impacts to the surrounding area. The proposal involves rehabilitation of an existing airport facility with no permanent operational impacts to adjoining parcels. The proposal does not create any need for additional SPECIAL GRADE/FILL PERMIT - 6 2 3 4 5 6 7 screening or landscaping nor is any screening or landscaping required by Renton regulations. A negligible amount of impervious surface will be added by the proposal and as discussed in FOF No.5 the City's stormwater regulations and proposed drainage improvements are more than adequate to mitigate any drainage issues created by the proposal. The most significant adverse impacts are arise from construction, in particular noise and dust caused by the hauling of materials and the on-site excavation and grading activities. These issues are addressed by limited hours of construction and the conditions of approval. DECISION 8 The special grade/fill permit is approved subject to the following conditions: 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 1. The Applicant shall report any complaints regarding noise to a person designated by City Staff and how the complaint was resolved within 24 hours of receipt. City staff shall monitor all complaints it receives from the Applicant and the public and shall restrict construction activities as reasonably necessary to mitigate anyon-going unreasonable noise impacts. 2.

New drainage structures would be constructed to facilitate capture of stormwater from re- contoured pavement and turf areas. Taxiway Designation System Modifications: A new taxiway designation system would be developed and the existing airfield signage system would be modified as necessary to reflect the new designations. The existing designations that include designators such as G, H, N, etc., are proposed to be changed to AI, A2, 81, 82 etc. This change would result in a need for new signage, including sign hardware ·and concrete foundations. Taxiway Edge Lighting Modifications: Taxiway edge lighting is proposed to be adjusted or replaced as necessary to be compatible with new pavement surfaces that result from the taxiway rehabilitation /reconstruction. 4. Surrounding Area. The subject site is bordered: on the north by Lake Washington, on the east by the Cedar River, and to the south and west primarily by commercial development. 5. Adverse Impacts. There are no significant adverse impacts associated with the proposal. Pertinent impacts are addressed in more detail below: Noise. The greatest issue of concern is noise. As testified by the project engineer, the proposal . will involve over 200 trucks carrying fill over a 63 day period. Part of the truck haul route will involve areas with multi-family housing along Rainier Avenue and Airport Way. Haul hours are limited by the MDNS between 8:30 am and 3:30 pm Monday through Friday unless otherwise approved by the Development Services Division. Construction hours overall are limited by the MDNS to 7:00 am to 8:00 pm, Monday through Friday and 9:00 am and 8:00 pm on Saturdays. City staff testified that the haul route and noise impacts will be evaluated and addressed during administrative permit review of the proposal. The conditions of approval will impose a noise monitoring program to ensure that noise mitigation measures adequately protect City residents from construction noise impacts. Drainage. Stormwater impacts will be negligible and are fully addressed by the City's stormwater 26 regulations and the Applicant's drainage control plan and TIR., Ex. 7 and II. Phase 2 would SPECIAL GRADE/FILL PERMIT -4 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 result in an increase in impervious surface coverage by eight-tenths of one percent over the existing 234,700 square feet of existing impervious surface area. The Applicant has proposed to upgrade the existing surface water drainage facilities with a combination of wet biofiltration swales, filter strips, catch basins, DIP, and high-density polyethylene (HDPE) pipe. The provided TIR has indicated that along the eastern side of the taxiway crown, surface water would typically be collected and conveyed through catch basins and sent to the western side of the taxiway, within the grass infield area. These concentrated flows would be discharged into a flow splitter device for water quality measures. Water quality for the concentrated flows would be conveyed through a wet biofiltration swale. The TIR identifies that the swale would be designed to meet the King County Service Water Design Manual (KCSWDM) basic treatment criterion of removing 80 percent of the total suspended solids. After leaving the biofiltration swale the stormwater is proposed to be collected in a catch basin and diverted toward the east through a series of surface water facilities and finally discharge to the Cedar River. The TIR describes the stormwater proposal for the western side of the taxiway crown as all non concentrated flows which would be treated by filter strips, which would then be conveyed to catch basins where the water would combine with the treated flow from the wet biofiltattion swale. Overall the project would not change the stormwater discharge locations as it currently exists today. Section 2 of the TIR identifies that the project would use Best Management Practices (BMPs) for flow control and would install such measure in accordance with the .requirements of the KCSWDM. Furthermore a Stormwater Pollution Prevention Plan (SWPPP) for the construction activities would be developed as a part ofthe overall project. Dust. In the Technical Information Report (TIR) it is identified that the contractor shall control dust to prevent sediment transport from exposed, dry surfaces to the adjacent waterways. It is anticipated that the Contractor would use water for dust control; however the KCSWDM permits the use of other methods to control dust. Critical Areas. There are no critical areas on site. The project is within 200 feet of the Cedar River but is exempt from requiring a shoreline substantial development permit. Screening and Landscaoinl?. No screening or fencing is required by the City of Renton Development Standards for the Airport Use. However, the Airport currently maintains a perimeter fence and ground cover landscaping in any area not covered by impervious surfaces. Airport operations and regulations are determined by the Federal Aviation Administration (FAA), which includes recommendation on Building Restriction Lines (BRL) i.e. Setbacks. Pursuant to the FAA Advisory Circular/ISO _5300 _13a BRL should be set beyond the Runway Protection zones, the Object Free Zones, the Object Free Areas, the runway visibility zone, etc... The project would comply with all FAA regulations. The closest point of work to the Ordinary High Water Mark (OHWM) of the Cedar River is 64 feet from the flood wall (which is estimated to be the approximate location of the OHWM). Approximately 430 feet of the north end of Taxiway B lies within the 200 foot Shoreline SPECIAL GRADEIFILL PERMIT - 5 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20· 21 22 23 24 25 26 Jurisdiction. Under current conditions the taxiway functions effectively with the existing fencing, landscaping and setbacks. The rehabilitation project would not result in any changes to the existing screening, landscaping, fencing and setback conditions at the subject site. Conclusions of Law Procedural: I. Authority of Hearing Examiner. RMC 4-9-080(F)(J)(a) provides that the hearing examiner is responsible for granting special pennits for fill and grade for grading and/or excavation involving more than 500 cubic yards of minerals or materials. Phase 2 of the proposal involves more than 500 cubic yards of grading and excavation. Substantive: 2. Applicable Standards. RMC 4-9-080(F)(4) governs the criteria for special fi11lgrade pennits. Applicable criteria are quoted below in italics and applied through corresponding conclusions of law. RMC 4-9-080(F)(4): To grant a special permit, the Hearing Examiner shall make a determination that .. the proposed activity would not be unreasonably detrimental to the surrounding area. The Hearing Examiner shall consider, but is not limited to, the following: 3. i. Size and location ofthe activity. ii. Traffic volume and patterns. iii. Screening, landscaping, fencing and setbacks. iv. Unsightliness, noise and dust. v. Surface drainage. vi. The length of time the application of an existing operation has to comply with nonsafety provisions of this Title. As detennined in Finding of Fact No.5, there are no significant adverse impacts associated with the proposal, wmch would include unreasonably detrimental impacts to the surrounding area. The proposal involves rehabilitation of an existing airport facility with no pennanent operational impacts to adjoining parcels. The proposal does not create any need for additional SPECIAL GRADE/FILL PERMIT - 6 2 3 4 5 6 7 8 9 10 II 12 13 14 screening or landscaping nor is any screening or landscaping required by Renton regulations. A negligible amount of impervious surface will be added by the proposal and as discussed in FOF No.5 the City's stormwater regulations and proposed drainage improvements are more than adequate to mitigate any drainage issues created by the proposal. The most significant adverse impacts are arise from construction, in particular noise and dust caused by the hauling of materials and the on-site excavation and grading activities. These issues are addressed by limited hours of construction and the conditions of approval. DECISION The special grade/fill permit is approved subject to the following conditions: I. The Applicant shall report any complaints regarding noise to a person designated by City Staff and how the complaint was resolved within 24 hours of receipt. City staff shall monitor all complaints it receives from the Applicant and the public and shall restrict construction activities as reasonably necessary to mitigate anyon-going unreasonable noise impacts. 2. The Applicant shall comply with all measures recommended and/or proposed m the Technical Information Report, Ex.

The Planning Division of the City of Renton accepted the above master application for review on July 3, 2012 and determined complete on July 24, 2012. The project was placed on hold August 6, 2012 and taken off hold October 29, 2012. The project complies with the 120-day review period. 4. The subject site is bordered: on the north by Lake Washington, on the east by the Cedar River, and to the south and west primarily by commercial development. 5. The property is located within the Employment Area Industrial (EAI) Comprehensive Plan land use designation, the Industrial Medium (1M) zoning classification. 6. The site is currently an operating Municipal Airport and contains many structures related to airport functions. Overall eXisting structures on the Airport site total 341,989 square feet in area. 7. The overall project consists of four parts, taxiway rehabilitation/reconstruction, storm drain lines and hydrant water lines rehabilitation, taxiway designation system modifications, and taxiway edge lighting modifications. a. Taxiway Rehabilitation/Reconstruction: Rehabilitation of the existing east side taxiway system pavements, including the taxiway connections to the runway from Taxiway 'N' at the north and to the south connection at Runway 34. It is anticipated that the pavement rehabilitation/reconstruction could employ various partial depth or full depth reconstruction methods including hot mix asphalt section reconstruction, reconstruction utilizing Portland Cement Concrete, and milling of the existing asphalt pavement surface followed by re-paving of new asphalt surface. b. Storm Drain Lines and Hydrant Water Line Rehabilitation: This would include replacing several failing concrete storm drain lines with ductile iron that cross Taxiway Band K. A portion of an existing water line in the vicinity of the south end of the project site would be evaluated for likely replacement as part of Phase 2. Surface grades and associated drainage efficiency within turf infield areas between Taxiway B and Runway 34 will be evaluated. These areas may require re-grading to alleviate existing storm water ponding issues. New drainage structures would be constructed to facilitate capture of stormwater from re-contoured pavement and turf areas. c. Taxiway Designation System Modifications: A new taxiway designation system would be developed and the existing airfield signage system would be modified as necessary to reflect the new deSignations. The existing designations that include designators such as G, H, N, etc., are proposed to be changed to AI, A2, 61, 62 etc. This change would result in a need for new signage, including sign hardware and concrete foundations. d. Taxiway Edge Lighting Modifications: Taxiway edge lighting is proposed to be adjusted or replaced as necessary to be compatible with new pavement surfaces that result from the taxiway rehabilitation /reconstruction. 8. The subject site is located within 200 feet of the Ordinary High Water Mark (OHWM) of the Cedar River Reach A. Located in the Shoreline High Intensity Overlay. 9. There are no critical areas on site. 10. Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on November 19, 2012, the City's Environmental Review Committee issued a Determination of Non- Significance -Mitigated (DNS-M) for the Taxiway B Rehabilitation Project. The DNS-M included two mitigation measures. A 14-day appeal period commenced on November 30, 2012 and will end on December 14, 2012. No appeals of the threshold determination have been filed to date. 11. No public or agency comments were received.

Hearing Date December 18, 2012 Page 5 of 7 12. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. 13. The following table contains project elements to be considered by the Hearing Examiner when making a determination on a Special Grade and Fill Permit, as outlined in RMC 4-9-080.F.4: SPECIAL GRADE AND FILL PERMIT CRITERIA: a. SIZE AND LOCATION OF THE ACTIVITY: The applicant is seeking approval of a Special Fill and Grade Permit to allow the rehabilitation of the south end of Taxiway B including drainage, pavement, striping, sign age, and water main replacement. The entire Taxiway is proposed to be rehabilitated however only Phase 2 triggers the requirement for a Special Grade and Fill Permit. Phase 2 would require approximately 6,700 cubic yards of gravel, import borrow material, topsoil and new asphalt to renovate the taxiway. The Renton Municipal Airport is located at 616 West Perimeter Road and is 167.38 acres, however the specific project area is approximately 7.84 acres for both Phase 1 and 2 of the taxiway rehabilitation. Phase 2 would result in an increase in impervious surface coverage by eight-tenths of one percent over the existing 234,700 square feet of existing impervious surface area. b. TRAFFIC VOLUMES AND PATIERNS: The applicant has indicated the construction would occur Monday through Friday from 7 a.m. to 6 p.m. The specific hauling routes would be determined by the successful bidder of the project; however the route is likely to include Airport Way South west to Rainier Avenue South then south to Interstate 405. All construction would occur along the taxiway and would not involve public streets. The applicant has indicated that the number and frequency of additional vehicular trips attributable to the construction is not anticipated to significantly impact public streets providing access to the site. Furthermore, airplane traffic that would normally use the subject portions of the taxiway being renovated would be directed to a safe alternate route at the Airport. c. SCREENING, LANDSCAPING, FENCING AND SETBACKS: No screening or fencing is required by the City of Renton Development Standards for the Airport Use. However, the Airport currently maintains a perimeter fence and ground cover landscaping in any area not covered by impervious surfaces. Airport operations and regulations are determined by the Federal Aviation Administration (FAA), which includes recommendation on Building Restriction lines (BRL) i.e. Setbacks. Pursuant to the FAA Advisory Circular/150_5300_13a BRL should be set beyond the Runway Protection zones, the Object Free Zones, the Object Free Areas, the runway visibility zone, etc... The project would comply with all FAA regulations. The closest point of work to the Ordinary High Water Mark (OHWM) of the Cedar River is 64 feet from the flood wall (which is estimated to be the approximate location of the OHWM). Approximately 430 feet of the north end of Taxiway B lies within the 200 foot Shoreline Jurisdiction. Under current conditions the taxiway functions effectively with the existing fencing, landscaping and setbacks. The rehabilitation project would not result in any changes to the existing screening, landscaping, fencing and setback conditions at the subject site d. UNSIGHTLINESS, NOISE, DUST: During project construction there will be areas of disturbance. However, this is a temporary project and areas of disturbance will be restored and enhanced. In the Technical Information Report (TIR) it is identified that the contractor shall control dust to prevent sediment transport from exposed, dry surfaces to the adjacent waterways. It is anticipated that the Contractor would use water for dust control; however the KCSWDM permits the use of other methods to HEX report 12-052.doc City of Renton Department of Co",~unity & Economic Development Hearing Examiner Recommendation TAXIWAY B REHABILITATION PR ..;:.:.T ___________________ ...:L::11::::A~1;:2:::-0~5::2~, E::,;C:;F.:., :::SP:..:,---=S;::M;::E:.- Hearing Date December 18, 2012 Page 6 of 7 control dust. During construction, equipment operation would temporarily increase noise levels in the vicinity. Construction equipment may produce temporary noise levels. However, construction noise levels are not anticipated to be higher than typical airport operations. The completed project, however, would not change existing noise levels. The proposed project may generate some dust during the transport and deposit of fill. e. SURFACE WATER: The applicant submitted a Technical Information Report (TIR) for both Phase 1 and Phase 2 prepared by Reid Middleton, dated October 2012 with the application. The applicant has proposed to upgrade the existing surface water drainage facilities with a combination of wet biofiltration swales, filter strips, catch basins, DIP, and high-density polyethylene (HDPE) pipe. The provided TIR has indicated that along the eastern side of the taxiway crown, surface water would typically be collected and conveyed through catch basins and sent to the western side of the taxiway, within the grass infield area. These concentrated flows would be discharged into a flow splitter device for water quality measures. Water quality for the concentrated flows would be conveyed through a wet biofiltration swale. The TIR identifies that the swale would be designed to meet the King County Service Water Design Manual (KCSWDM) basic treatment criterion of removing 80 percent of the total suspended solids. After leaving the biofiltration swale the stormwater is proposed to be collected in a catch basin and diverted toward the east through a series of surface water facilities and finally discharge to the Cedar River. The TIR describes the stormwater proposal for the western side of the taxiway crown as all nonconcentrated flows which would be treated by filter strips, which would then be conveyed to catch basins where the water would combine with the treated flow from the wet biofiltattion swale. Overall the project would not change the stormwater discharge locations as it currently exists today. Section 2 of the TIR identifies that the project would use Best Management Practices (BMPs) for flow control and would install such measure in accordance with the requirements of the KCSWDM. Furthermore a Stormwater Pollution Prevention Plan (SWPPP) for the construction activities would be developed as a part of the overall project. f. REUSE OF SITE: The rehabilitation project is designed to improve the existing taxiway so the site can be used for aviation use now and in the future. No further reuse analysis is needed. g. TRANSFERABILITY OF SPECIAL PERMIT: This permit is for a one-time project. h. Permit Expiration: This is a one-time project of relatively short duration. The anticipated construction period for Phase 2 is the summer and early fall of 2013. i. Revocation of Permit: The Community and Economic Development Department is authorized to revoke any annual license issued pursuant to the terms of the Grading, Excavation and Mining Regulations if after due investigation it is determined that the permittee has violated any of the provisions of this Ordinance. Notice of revocation shall have reasonable time not to exceed forty-five (45) days in which to remedy the defects or omission specified. In the event that the licenses fails or neglects to do so within the time period, the order of revocation shall be final. A total or partial stop work order may be issued for good reason. I,. CONCLUSIONS: 1. The proposal complies with the Special Grade and Fill Permit review criteria. 2. The proposal would not be unreasonably detrimental to the surrounding area. 3. The proposal is compliant and consistent with City of Renton plans, policies, regulations and approvals.

JUL -3 2011 TAXIWAY B -NORTH (GENERAL AVIATION) SECTION IMPROVEMENTS Renton Municipal Airport Taxiway B Rehabilitation Renton, Washingtoll 2011-039-21 April 27, 2012 The purpose of this technical memorandum is to provide a concise summary of the pavement and sub surface conditions we observed within the North (General Aviation-North of the wind rose) section of Taxiway B and provide generalized recommendations for treatment of sub soils that can be incorporated into remedial design. This memorandum draws from information previously published in our Draft Geotechnical Engineering Report, Renton Municipal Airport, Taxiway B Rehabilitation, published on July 28, 2011. EXISTING PAVEMENT STRUCTURE As part of our subsurface investigation, we completed 5 core!hand holes, distributed evenly along the taxiway alignment and on the existing tie-doWn apron area: Based on these relatively limited explorations (Core-O 1 Core-02, and Core-05), the pavement structure along the north portion of Taxiway B consists of an HMA surface of about 2 to 4.5 inches thick and a base course layer of about 5 to 6 inches thick. The existing pavement surface is in fair to good condition. Within the apron area adjacent to the private hangers (Core-03and Core-04), the pavement section consists of an HMA surface layer of about 1.5 to 2.25 inches thick. At the location of Core-04, a 1.5-inch thick layer of crushed aggregate was found sandwiched between the surface course ofHMA and an older 1.75 inch thick layer ofHMA. A thin gravel base layer about 1.5 -inches thick was encountered under the pavement at Core-03. No gravel base was ericountere~ below the. lower HMA layer in Core-04. The existing pavement surface within the apron area is in poor to fair condition. In general, the type of distress exhibited by the pavement . surface in these areas indicates that drainage is inadequate and the pavement section composed . of2 to 4.5-inches ofHMA over 0 to 6 inches of base course is too thin to'" 2131230th Drive SE I · dl d Suite 110 supporLc.urrenLapp Ie. • Olli S'u Bothell, WA 98021.7010 Te~ 425.174.0106 Fax. 425.774.2714 www.hwageoocom Technical infmrmation Report (TIR) for Rentonn Municipa!

No work would occur outside the Airport site. Under current conditions the Airport is developed with a number of existing buildings, hangars, an air traffic control tower, office and fixed based operations and other airport related uses. The proposed project would not result in changes to any of the existing structures. The site is bordered by Lake Washington to the North, the Cedar River to the east, Commercial Arterial (CA) zoned property to the south and primarily CA zoned property to the west across Rainer Avenue N. The overall project consists of four parts, taxiway rehabilitation/reconstruction, storm drain lines and hydrant water lines rehabilitation, taxiway designation system modifications, and taxiway edge lighting modification, Each part of the project is described in more detail in the table below. Taxiway Rehabilitation of the existing east side taxiway system pavements, Rehabilitation/Reconstruction including the taxiway connections to the runway from taxiway 'N' at the north and to the south connection at Runway 34. It is anticipated that the pavement rehabilitation/reconstruction could employ various partial depth or full depth reconstruction methods including hot mix asphalt section reconstruction, reconstruction utilizing Portland Cement Concrete, and milling of the existing asphalt pavement surface followed by re-paving of new asphalt surface. Storm Drain Lines and This would include replacing several failing concrete storm drain lines with Hydrant Water Line ductile iron that cross Taxiway Band K. A portion of an existing water line Rehabilitation in the vicinity of the south end of the project sit would be evaluated for likely replacement as part of Phase 2. Surface grades and associated drainage efficiency within turf infield areas between Taxiway Band Runway 34 will be evaluated. These areas may require regarding to alleviate existing stormwater ponding issues. New drainage structures would be constructed to facilitate capture of stormwater from re- contoured pavement and turf areas. Taxiway Designation System A new taxiway designation system would be developed and the existing Modficaitons airfield signage system would be modified as necessary to reflect the new designations. The existing designations that include designators such as G, H, N, etc., are proposed to be changed to Ai, A2, Bl, B2 etc. This change would result in a need for new signage, including sign hardware and concrete foundations. Taxiway Edge Ligthing Taxiway edge lighting is proposed to be adjusted or replaced as necessary Modfiications to be compatible with new pavement surfaces that result form the taxiway rehabilitation /reconstruction. ERe ReporC12-052.doc City of Renton Department of Community & r:"onomic Development TAXIWAY B REHABILITATION PROJECT Environmental Review Committee Report WAI2·0S2, ECF, SP Report of November 19, 2012 Page 3 of 8 The rehabilitation project is divided into two phases; Phase 1 consists of rehabilitation of the north portion of Taxiway B which is exempt from a Special Grade and Fill Permit, Pursuant to RMC 4·9·080C.6. Phase 2 would rehabilitate the south end of Taxiway B and is required to obtain a Special Grade and Fill Permit, which is included in the application. Both Phase 1 and 2 would include new storm drainage, pavement, striping, directional safety signage and taxiway edge lighting. Phase 2 would also include a replacement of a water main. Both Phase 1 and 2 would require a Shoreline Exemption as both are located within 200 feet of the Ordinary High Water Mark (OHWM) of the Cedar River. The closest point of work is 64 feet from the flood wall which is estimated to be the approximate location of the OHWM. Phase 1 is anticipated to begin construction during the spring and early summer of 2013 and Phase 2 is scheduled to be started in late summer and early fall of 2012 pending Federal Aviation Administration (FAA) funding constraints. Approximately 2,250 cubic yards of gravel, import borrow material, topsoil and new asphalt would be required to bring the renovated taxiway to design grade for Phase 1 and 6,700 cubic yards would be required to be imported for Phase 2. Both phase 1 and 2 are anticipated to increase existing impervious surface. Phase 1 would increase impervious surface by one half percent over the existing 104,110 square feet and phase 2 would increase impervious surface by eight·tenths of one percent over the existing 234,700 square feet of existing impervious surface area. I PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations.

Environmentallmpacts Environmental Review Committee Report LUAll·OS2, ECF, SP Page 4 of 8 The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The applicant submitted a Draft Geotechnical Engineering Report and a Technical Memorandum for the Section Improvements both prepared by HWA GeoSciences Inc., dated July 28,2011 and October 17, 2012 respectively. Based on the provided Geotechnical Report Taxiway B is approximately 3,300 feet long, and 25 -SO feet wide, and consists of asphaltic concrete pavement in the general aviation area and Portland Cerement concrete panels overlain by asphaltic concrete in the area trafficked by large commercial aircraft. The ground surface in the vicinity of this project is predominantly flat. HWA conducted subsurface investigation by means ofthree test pits and twenty pavement cores ranging in depths from 3.5 to 4 feet, in addition to hand boring. In addition to the test pits and pavement cores HWA conducted Dynamic Cone Penetration (DCP) testing to check relative soil density/strength conditions. The data obtained from the DCP test is then correlated to approximate California Bearing Ratio (CBR) values, in order to evaluate the strength of the subgrade soils. The provided Geotechnical Report identified that the native soils consists predominately of soft to medium stiff organiC or sandy silts within the northern and central portions of the project alignment. These subgrade soils are weak exhibiting in-place CBR values ranging from 1 to 5 percent and averaging about 3 percent. Furthermore, the report identified that within the southernmost portion of the project alignment, in the infield cut-out area (Core-lO) and at the southern end of Taxiway B (Core -11) the pavement is underlain by granular fill and sandy alluvial soils. The subgrades at this location appear to be moderately strong exhibiting estimated in-place CBR values ranging from 19 to 40 percent. Additionally the report addressed soil conditions along the main portion of the southern taxiway connector and identified the pavement is underlain by loose to medium stiff, silty sand to sandy silt alluvial soils and at other locations the pavement is underlain by relatively thick sections of strong granular fill and native materials exhibiting estimated in-place CBR values ranging from SO to 100 percent. The provided Geotechnical Report evaluated the local water table and concludes that seasonally perched ground water would be encountered at depths ranging from 2.2 to 5.4 feet below the existing ground surface. The report concludes that the ground water level in the area is high and would be especially high during the wet weather season. The report further concludes that the presence of a high ground water table further decreases the already low infiltration potential of the subgrade soils. Following this conclusion, the report provides recommendations on drainage below the pavement and along the edge of the taxiways. Due to the potential for premature pavement distress and frost-heaves effects as a result of ground water staff recommends as a mitigation measure that the applicant comply with the recommendation included in the Geotechnical Report. The provided Technical Memorandum was prepared to provide a concise summary of the pavement and sub-surface conditions observed within the North section of Taxiway B and provide generalized recommendations for treatment of sub soils that can be incorporated into remedial ERe ReporC12·052.doc City 0/ Renton Department 0/ Community & __ .,momic Development TAXIWAY B REHABILITATION PROJECT . Report of November 19, 2012 Environmental Review Committee Report WA12-0S2, ECF, SP Page 5 of 8 design. This Memorandum is based off the information included in the Geotechnical Report referenced above. The Technical Memorandum states that the existing pavement surface within the apron area is in poor to fair condition. In general, the type of distress exhibited by the pavement surface in these areas indicate that drainage is inadequate and a pavement section comprised of 2 to 4.5 inches of Hot Mix Asphalt (HMA) over 0 to 6 inches of base course is too thin to support current applied loads. Based on this conclusion the Technical Memorandum provides recommendations on subgrade preparation including granular subgrade and silt subgrade, cement treatment, geogrid reinforcement, and underdrains. As such, staff recommends as a mitigation measure that the applicant comply with the recommendations included in the Technical Memorandum. Mitigation Measures: The applicant shall comply with the recommendations included in the Geotechnical Engineering Report and the Technical Memorandum prepared by HWA GeoSciences Inc., dated October 17, 2012 and April 27, 2012 respectively. Nexus: SEPA Environmental Review, RMC 4-3-050 Critical Areas Regulations, RMC 4-4-060 Grading, Excavation and Mining Regulations. 2. Water a. Wetland, Streams, Lakes Impacts: The subject site is located within 200 feet of the Ordinary High Water Mark (OHWM) of the Cedar River and therefore is located in the Shoreline High Intensity Overlay. The closest point of work is 64 feet from the flood wall which is estimated to be the approximate location of the OHWM. Approximately 430 feet of the north end of Taxiway B lies within the 200 foot Shoreline Jurisdiction. The subject project has been identified as an essential public facility pursuant to the Administrator of the Department of Community and Economic Development. Therefore, the project would be exempt from Buffers and Setbacks pursuant to RMC 3-4-090D.7.d.vi. However the project has designed and constructed the development to meet the specified dimensional standards to the maximum extent feasible. Mitigation Measures: No further mitigation required Nexus: N/A b. Storm Water Impacts: The applicant submitted a Technical Information Report (TIR) for both Phase 1 and Phase 2 prepared by Reid Middleton, dated October 2012 with the application. Based on the provided TIR the site is located in the Lower Cedar River Basin and Cedar Outfall Subbasin. The TIR describes existing stormwater conditions of the project, which identify that the taxiway and runway slope inward toward the grass infield area where surface water is directed, through depressions or swales towards catch basins near the western side of Taxiway B. The.flow is then collected in the catch basins, diverted through a series of pipes and catch baSins, and then discharged through outfalls along the western side of the Cedar River. The applicant has proposed to upgrade the existing surface water drainage facilities with a combination of wet biofiltration swales, filter strips, catch baSins, DIP, and high-density polyethylene (HOPE) pipe. The provided TIR has indicated that along the eastern side o(the taxiway crown, surface water would typically be collected and conveyed through catch basins and sent to the western side of the taxiway, within the grass infield area. These concentrated flows would be discharged into a flow splitter device for water quality measures. Water quality for the ERe ReporC12-052.doc City of Renton Department of Community (. .lOomic Development TAXIWAY B REHABILITATION PROJECT Report of November 19, 2012 Environmental Review Committee Report LUA12·0S2, ECF, SP Page 6 of 8 concentrated flows would be conveyed through a wet biofiltration swale. The TIR identifies that the swale would be designed to meet the King County Service Water Design Manual (KCSWDM) basic treatment criterion of removing 80 percent of the total suspended solids. After leaving the biofiltration swale the stormwater is proposed to be collected in a catch basin and diverted toward the east through a series of surface water facilities and finally discharge to the Cedar River. The TIR describes the stormwater proposal for the western side of the taxiway crown as all nonconcentrated flows which would be treated by filter strips, which would then be conveyed to catch basins where the water would combine with the treated flow from the wet biofiltattion swale. Overall the project would not change the stormwater discharge locations as it currently' exists today. Section 2 of the TIR identifies that the project would use Best Management Practices (BMPs) for flow control and would install such measure in accordance with the requirements of the KCSWDM. Furthermore a Stormwater Pollution Prevention Plan (SWPPP) for the construction activities would be developed as a part of the overall project. Mitigation Measures: No further mitigation required Nexus: N/A 3. Historic and Cultural Preservation Impacts: The subject site is located in an area of known Cultural Resources. The Black River once flowed near the subject site connecting to the White River. Developments within the vicinity of the old Black River channel are more likely to be sites where significant historic and/or cultural resources would be found, and the subject development has indicated that site grading would be conducted. Therefore, staff recommends a mitigation measure that requires the applicant and/or developer to stop work and immediately notify the City of Renton Planning Division, concerned Tribes' cultural committees, and the Washington State Department of Archeological and Historic Preservation if any Native American grave(s) or archaeological/cultural resources (Indian artifacts) are found. Mitigation Measures: If any Native American grave(s) or archaeological/cultural resources (Indian artifacts) are found, all construction activity shall stop and the owner/developer shall immediately notify the City of Renton Planning Division, concerned Tribes' cultural committees, and the Washington State Department of Archeological and Historic Preservation. Nexus: SEPA Environmental Regulations E. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers. Where applicable, their comments have been incorporated into the text of this report and/or "Advisory Notes to Applicant." .,( Copies of all Review Comments are contained in the Official File and may be attached to this report.

The applicant is encouraged to review all applicable sections ofthe 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 at 300 Airport Way, the Renton Municipal Airport. The proposed project would Taxiway B and connecting taxiways rehabilitation/reconstruction, storm drain lines and hydrant water lines rehabilitation, taxiway deSignation system modification, and taxiway edge lighting modification. No other modifications to the existing Airport are proposed. Current Use: Currently the subject site is an operating MunicipalAirport. Zoning: The subject site is located within the Medium Industrial (1M) zoning designation. The site is also located within the Employment Area Industrial Comprehensive Plan deSignation. The proposed use would be an airport, which is a permitted use in the 1M zone. The subject site is located within the Shoreline Hig~ Intensity environment in both lake Washington reach J and Cedar River reach A. Development Standards: The project would be subject to RMC 4-2-130A, "Development Standards for Industrial Zoning Designations" and the City of Renton's Shoreline Master Program (SMP) because the subject project is located near Lake Washington and the Cedar River. Many of the 1M development standards would not be applicable because of the nature ofthe subject project. As such, the following report only addresses the applicable development standards and/or shoreline regulations. Shoreline Regulations: The objective of the. High Intensity Overlay is to provide opportunities for large-scale office and commercial employment centers as well as multi-family residential use and Airport Taxiway B system Rehabilita •. _ .. February 16, 2012 Page 2 of 3 public services. This district provides opportunities for water-dependent and water-oriented uses while protecting existing ecological functions and restoring ecological functions in areas that have been previously degraded. Development may also provide for public use and/or community use, especially access to and along the water's edge. RMC 4-3-090E.10.f addresses Aviation in the SMP, see regulations below: ii. Airports: (a) A new airport shall not be allowed to locate within the shoreline; however, an airport already located within a shoreline shall be permitted.

(d) Helipads may be included as an accessory use in any existing airport. (e) Aviation-related manufacturing shall be permitted in an airport. (f) New or upgraded airport facilities shall be designed and operated such that: (1) All facilities that are non-water-dependent shall be located outside ofshoreline jurisdiction, if feasible. When sited within shoreline jurisdiction, uses and/or developments such as parking, hangars, service buildings or areas, access roads, utilities, signs, and storage of materials shall be located as far from the land/water interface as feasible. The minimum setback shall be twenty feet (20') from the OHWM of the shoreline and shall be designed and spaced to allow viewing of airport activities from the area along the water's edge. (2) New or upgraded airport facilities shall minimize impacts on shoreline ecological functions, including control cif pollutant discharge. The standards for water quality and criteria for application shall be those in current stormwater control regulations. (3) New facilities dispensing fuel or facilities associated with use of hazardous materials shall require a Shoreline Conditional Use Permit. Critical Areas: The. City of Renton's Critical Areas Maps indicate that the subject site is within the vicinity of seismic hazards, flood hazards, habitat conservation area and Shorelines of the State (Lake Washington & the Cedar River). Lake Washington and the Cedar River are Class 1 waterways of the state, any development within 200-feet of the ordinary high water mark of a Class 1 waterway, are required to comply with the Shoreline Master Program (as discussed above). The subject site contains a Flood Hazard Area; pursuant to the FIMA Flood Insurance Rate Maps (FIRM) the subject site contains a Special Flood Zone AE (base flood elevation determined) which is classified as a 100-year flood plain.

The average depth of fill to create , the crowned taxiway surface referenced in the Phasing section below is less than one foot as compared to the existing taxiway elevation. ' , Sign Permit from the City of Renton Zoning: Medium Industrial Current Use of Site and any existing improvements: The site is a portion of the Renton Municipal Airport and is one of two parallel taxiways serving the airport main runway. Buildings at the airport include hangars, the airport office and tower, office and operations space for fixed base operators, and other airport-related ,land uses. , Special Site Features: The Renton Municipal Airport borders Lake Washington along the north boundary and the Cedar River along the east boundary. Soil type and drainage conditions: Surficial soil deposits in the vicinity of the airport are identified as urban or industrial land that has been modified by widespread or discontinuous artificial fill. The native ,subgrade beneath the taxiway consists predominately of medium stiff to soft organic silt. Stormwater runoff on the north end of the project site is collected in catch basins and surface swales and eventually , discharged directly to the Cedar River,Stormwater runoff on the south end of the project site is collected in catch, basins and surface swales and discharges to an Oil/water separator vault on that portion of the airport leased to Boeing. The water quality vault in turn discharges to the Cedar River through a pipe, Proposed Use of the property and scope of the proposed development: TAXIWAY '6' AND CONNECTING TAXIWAYS REHABILITATION/RECONSTRUCTION This portion of the project consists of rehabilitating all of.the existing east side taxiway system , pavements, including the parallel Taxiway 'B: plus its taxiway connectionsto the runway from Taxiway 'N' at the north and to the south connection at Runway 34. It is antiCipated that the pavement rehabilitation/reconstruction could employ various partial depth or full depth reconstruction methods including hot mix asphalt section reconstruction, reconstruction utilizing Portland Cement Concrete, and milling of the existing asphalt pavement surface followed by re- paving of a new asphalt surface. The choice of preferred rehabilitation/reconstruction options will be based 'on: o Accommodation of contouring of pavement surfaces. o Adequate pavement strengths to serve anticipated aircraft loadings. ,0 Constructibility considerations. o Cost efficiency. o Long-term performance. ) STORM DRAIN LINES AND HYDRANT WATER LINES REHABILITATION Underground utility upgrading will be another element of the project. This will include replacing several failing concrete storm drain lines with ductile iron that cross Taxiways Band K. A portion of an existing water line in the vicinity of the south end of the project site will be evaluated for likely replacement as part of Phase 2. Surface grades and associated drainage efficiency within turf infield areas between Taxiway Band Runway 34 will be evaluated. These areas may require regrading to alleviate existing stormwater ponding issues. New drainage structures will be constructed to facilitate capture of stormwater from re- contoured pavement and turf areas. TAXIWAY DESIGNATION SYSTEM MODIFICATIONS A new taxiway connector designation system will be developed, and the existing airfield sign age system will be modified as necessary to reflect the new designations. The existing designations that include · designators such as G, H, N, etc., will be changed to designations such as Ai, A2, Bl, B2, etc. Since the new designation system will increase the number of characters, the sign module widths will increase correspondingly. It is anticipated that the existing sign hardware and concrete foundations will not be adequate in the majority of cases to accommodate the. new system and will require new construction to accommodate the new signage .. TAXIWAY EDGE LIGHTING MODIFICATIONS Taxiway edge lighting will be adjusted or replaced as necessary to be compatible with the new · pavement surfaces. PHASING Phase 1 consists of rehabilitating that portion of Taxiway "B" lying north of the "s-curve" jog about midway along the length of Taxiway "B". This portion of the project will include reconstruction of the taxiway to create a crowned taxiway surface to replace the existing "shed slope" surface. The work will include construction of new underdrains along both sides of the taxiway, construction of new storm drain line on the eastside of the south end of the project, as well as construction of a new slot drain system along the frontage of Building 749B (Rivers Hangar). Also included will be new pavement · striping, new directional safety signage, and new taxiway edge lighting. Phase 2 of the project will rehabilitate the south end of Taxiway "B" and will include the same type of drainage, pavement, striping, and signage work as described for Phase 1, but in addition will include replacement of a water main. Access: Access to the airport is off of Airport Way South at the south end of the airport. Proppsed off-site improvements: No off-site improvements are proposed. Estimated construction cost I fair market value of project: $11,726,000 Estimated quantitv of fill or excavation: , J Approximately 2250 cubic yards (as measured from the existing taxiway surface) of gravel, import borrow material, topsoil and new asphalt will be required to bring the renovated taxiway to design grade for Phase 1. Approximately 6700 cubic yards (as measured from the existing taxiway surface) of gravel, import borrow materia I; topsoil and new asphalt will be required to bring the renovated taxiway to design grade for Phase 2; Number. type. and size of trees to be removed: No trees are on the work site, thus none will be removed. land to be dedicated to the Citv: No land is proposed for dedication to the City (the City already owns the property) Proposed job schack:' The selected contractor will be required to provide a job shack for use by the contractor personnel and by the project consultant . . Distance of project work area from Ordinarv High Water Mark: The west bank of the Cedar River supports a. 20: to 30 foot wide strip of native vegetation along the entire project frontage with a flood wall located at the top of the embankment as shown on the project . site plan. The work site at its closest is approximately 64 feet from the flood wall that borders the Cedar River, which is upland from and varies from 5 to 30 feet in distance from the OHWM of the Cedar River . . Tree Cutting {land Clearing /Tree Inventorv) Plan: There are no trees on the project site or near the project site as they are considered a hazard to aviation. No trees will be planted as part of this project. Fill Source Statement: Both phases of the Taxiway "B" Renovation project will be competitively bid. The source of fill is thus subject to whatever fill source is proposed by the successful bidder. However, both the FAA (as partial funder of the project) and Renton Municipal Airport require that all fill materials imported to the site be procured from a site permitted and licensed to provide the types of materials required for the project.

The average depth of fill to create the crowned taxiway surface referenced in the Phasing section below is less than one foot as compared to the existing taxiway elevation. Sign Permit from the City of Renton Current and Proposed use of the site: Municipal Airport taxiway Special Site Features: The site lies along the west bank of the Cedar River and the shoreline of Lake Washington. Soil type and drainage conditions: Surficial soil deposits in the vicinity of the airport are identified as urban or industrial land that has been modified by widespread or discontinuous artificial fill. The native subgrade beneath the taxiway consists predominately of medium stiff to soft organic silt. Stormwater runoff on the north end of the project site is collected in catch basins and surface swales and eventually discharged directly to the Cedar River. Stormwater runoff on the south end of the project site is collected in catch basins and surface swales and discharges to an oil/water separator vault on that portion of the airport leased to Boeing. The water quality vault in turn discharges to the Cedar River through a pipe. Estimated construction cost I fair market value of project: $11,726,000 ,J Estimated quantity of fill or excavation: Approximately 2250 cubic yards (as measured from the existing taxiway surface) of gravel, import borrow material, topsoil and new asphalt will be required to bring the renovated taxiway to design grade for Phase l. Approximately 6700 cubic yards (as measured from the existing taxiway surface) of gravel, import borrow material, topsoil and new asphalt will be required to bring the renovated taxiway to design grade for Phase 2. Number, type. and size of trees to be removed: None Distance of project work area from Ordinary High Water Mark: The west bank of the Cedar River supports a 20-to 30 foot wide strip of native vegetation along the entire project frontage with a flood wall located at the top of the embankment as shown on the project site plan. The work site at its closest is approximately 64 feet from the flood wall that borders the Cedar River, which is upland from and varies from 5 to 30 feet in distance from the OHWM of the Cedar River. Nature of existing shoreline: The west bank of the Cedar River supports a 20-to 30 foot wide strip of native vegetation along the entire project frontage.

The average depth of fill to create the crowned taxiway surface referenced in the Phasing section below is less than one foot as compared to the existing taxiway elevation. Sign Permit from the City of Renton 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. TAXIWAY 'B' AND CONNECTING TAXIWAYS REHABILITATION/RECONSTRUCTION This portion of the project consists of rehabilitating all of the existing east side taxiway system pavements, including the parallel Taxiway '8: plus its taxiway connections to the runway from Taxiway 'N' at the north and to the south connection at Runway 34. It is anticipated that the pavement rehabilitation/reconstruction could employ various partial depth or full depth reconstruction methods including hot mix asphalt section reconstruction, reconstruction utilizing Portland Cement Concrete, and milling of the existing asphalt pavement surface followed by re-paving of a new asphalt surface. The choice of preferred rehabilitation/reconstruction options will be based on: o Accommodation of contouring of pavement surfaces. o Adequate pavement strengths to serve anticipated aircraft loadings. o Constructibility considerations. o Cost efficiency. o Long-term performance. STORM DRAIN LINES AND HYDRANT WATER LINES REHABILITATION Underground utility upgrading will be another element of the project. This will include replacing several failing concrete storm drain lines with ductile iron that cross Taxiways 8 and K. A portion of an existing water line in the vicinity of the south end of the project Site will be evaluated for likely replacement as part of Phase 2. Surface grades and associated drainage efficiency within turf infield areas between Taxiway 8 and Runway 34 will be evaluated. These areas may require regrading to alleviate existing stormwater ponding issues. New drainage structures will be constructed to facilitate capture of stormwater from re-contoured pavement and turf areas. H:ID0Cl23Ap1101007 Renton TW B & Si9nageIPermiHin91SEPA & Shoreline APP packagel050112 Renton envchlsldoc ·3· TAXIWAY DESIGNATION SYSTEM MODIFICATIONS A new taxiway connector designation system will be developed, and the existing airfield signage system will be modified as necessary to reflect the new designations. The existing designations that Include designators such as G, H, N, etc., will be changed to designations such as A1, AZ, B1, BZ, etc. Since the new designation system will increase the number of characters, the sign module widths will Increase correspondingly. It is anticipated that the existing sign hardware and concrete foundations will not be adequate in the majority of cases to accommodate the new system and will require new construction to accommodate the new signage. TAXIWAY EDGE LIGHTING MODIFICATIONS Taxiway edge lighting will be adjusted or replaced as necessary to be compatible with the new pavement surfaces. PHASING Phase 1 consists of rehabilitating that portion of Taxiway "B" lying north of the "s- curve" jog about midway along the length of Taxiway "B". This portion of the project will include reconstruction of the taxiway to create a crowned taxiway surface to replace the existing "shed slope" surface. The work will Include construction of new underdralns along both sides of the taxiway, construction of new storm drain line on the east side of the south end of the project, as well as construction of a new slot drain system along the frontage of Building 749B (Rivers Hangar). Also included will be new pavement striping, new directional safety signage, and new taxiway edge lighting. . Phase Z of the project will rehabilitate the south end of Taxiway "B" and will include the same type of drainage, pavement, striping, and signage work as described for Phase 1, but in addition will include replacement of a water main . .

This memorandum draws from information previously published in our Draft Geotechnical Engineering Report, Renton MuniCipal Airport, Taxiway B Rehabilitation, published on July 28, 2011. EXISTING PAVEMENT STRUCTURE As part of our subsurface investigation, we completed 5 core/hand holes, distributed evenly along the taxiway alignment and on the existing tie-down apron area. Based on these relatively limited explorations (Core-Ol Core-02, and Core-05), the pavement structure along the north portion of Taxiway B consists of an HMA surface of about 2 to 4.5 inches thick and a base course layer of about 5 to 6 inches thick. The existing pavement surface is in fair to good condition. Within the apron area adjacent to the private hangers (Core-03 and Core-04), the pavement section consists of an HMA surface layer of about 1.5 to 2.25 inches thick. At the location of Core-04, a 1.5-inch thick layer of crushed aggregate was found sandwiched between the surface course ofHMA and an older 1.75 inch thick layer ofHMA. A thin gravel base layer about 1.5 -inches thick was encountered under the pavement at Core-03. No gravel base was encountered below the lower HMA layer in Core-04. The existing pavement surface within the apron area is in poor to fair condition. In general, the type of distress exhibited by the pavement surface in these areas indicates that drainage is inadequate and the pavement section composed of2 to 4.5-inches ofHMA over 0 to 6 inches of base course is too thin to 2131230thDriveSE supporLcurrent applied.loads._ Suite 110 Bothell, WA 98021.7010.

The sub base soils are comprised of materials ranging from gravel with sand, silt and cobbles to poorly graded sand with silt. At the location of Core-OS, dredge fill consisting of silty medium sand with shell fragments, brick and glass fragments was encountered to the extent of our exploration depth at this location (about 2.5 feet). NATNE SUBGRADE Our subsurface investigations reveal that the native soils in the area consist predominately of soft to medium stiff organic (OLlOH) or sandy silts (ML) within the northern and central portions of the project alignment (TP-l, Core-02, Core-03, and Core-04). Native subgrade soils were encountered at depths ranging from 1.2 to 3.2 feet below the existing pavement surface. The Atterberg Limit tests performed on a subgrade sample from Core-02 revealed that the soil contains low plasticity fines and is categorized by the FAA as susceptible to frost effects, FG-4 (FAA, 2008). One subgrade soil sample obtained in this area was tested for CBR value. The tested sample was taken from Test Pit TP-l, which is representative of the soils encountered along the northern portion of the existing Taxiway location. The moisture-density curve for the sample was determined in general accordance with ASTM D 698, as required by FAA for airfield serving aircraft with total weight less than 60,000 Lbs. The CBR value for the material was determined at maximum effort (100% compaction per ASTM D 698) and at natural moisture content. The measured CBR test result was less than 1 %. Complete test results are presented in Appendix B of the Draft Report. Estimated in-place CBR values for these subgrade soils were determined by dropweight cone penetrometer (DCP) soundings conducted through the core holes. In general, the subgrade is soft to medium stiff exhibiting in-place CBR values ranging from I to 5%, and averaging about 3%. These values are higher than the laboratory CBR test and likely reflect variation in local moisture content and loss of strength due to remolding (sensitivity). The in-place moisture contents of these soils ranged from about 50 to 75 percent over what is optimum for compaction. FROST CONSIDERATIONS The organic silt subgrade soils at the project site are classified by FAA's Airport Pavement Design and Evaluation Advisory Circular (FAA, 2008) as FG-4, for frost susceptibility purposes. For FG-4 type of soils, the FAA recommends control of pavement deformations resulting from frost action by providing sufficient combined thickness of pavement and non-frost-susceptible material to eliminate, or limit to an acceptable amount, frost penetration into the subgrade and its adverse effects. Complete frost protection is accomplished by providing a sufficient thickness of North Taxiway B-Tech Memo 2 HW A GeoSciences Inc. April 27, 2012 HWA Project No. 2011-039-21 pavement and non-frost susceptible material to totally contain frost penetration. This method is intended to prevent underlying frost susceptible materials from freezing. Local design depth for frost penetration in the Renton area is 15 inches (WSDOT, 1995 Pavement Design Guide). The detrimental effects of frost action may be manifested by non- uniform heave, loss of soil strength during frost melting, loss of compaction, restriction of drainage, and cracking and deterioration of the pavement surface. Therefore, the design of pavements in areas subject to seasonal frost action requires special consideration. GROUNDWATER The local water table, or substantial seasonally perched ground water, was observed in explorations Core-04 and TP-l and TP-2, located within the north and central portions of the infield, ranging from 2.7 to 5.4 feet below the existing ground surface. We anticipate that ground water level in the area to be high; especially during the wet weather season and vary locally with the level of the adjacent Cedar River. This high ground water level will further reduce the already low infiltration potential of the subgrade soils. DISCUSSION AND RECOMMENDATIONS GENERAL Our subsurface investigations reveal that the existing pavement subbase soils consist of fills ranging from 0.5 to 2.2 feet thick and composed of sandy gravel (Core-Ol and Core-02), sand to silty sand (Core-03 and Core-04) or dredged fill (Core-OS). Beneath the subbase fill, native soft organic silt subgrade was encountered at depths ranging from 1.2 feet (Core-02) to 3.2 feet (Core-03). The loading expected in this area has been increased from 60, 000 pounds to about 78,000 pounds to support ARRF vehicles. We understand that likely total reconstruction of this portion of the airport taxiway is being considered consisting of a pavement section likely composed of 4-inches ofHMA over 6-inches of gravel base over a sub base layer in excess of 14-inches thick. At many locations in the north portion of the taxiway area, the two foot cut required to accommodate the proposed pavement section, and maintain current grade, will extend as much as 8 to 10 inches into the soft to medium stiff native subgrade. In the following sections, we discuss subgrade preparation and improvement alternatives that may be used to incorporate into design. SUBGRADE PREPARATION Granular Subgrade All existing HMA, base gravel and fill and/or native soil to a prescribed depth to accommodate the design section and sub base layer should be removed from areas to be paved. Where the excavation has exposed granular fill soils consisting of silty sand (SM), sandy gravel (GP) or sand with silt and gravel (SP-SM) , the surface should be thoroughly compacted to provide a dense and unyielding subgrade condition, which shoUld be confirmed by a geotechriicaJ engmeer North Taxiway B-Tech Memo 3 HW A GeoSciences Inc. J April 27, 2012 HWA Project No. 2011-039-21 prior to placement of any sub base material. Any loose or soft areas that exhibit instability should be over-excavated and replaced with structural fill comprised of crushed aggregate base course (P-209), and compacted to a dense and unyielding condition. This work should preferably be completed during dry weather. Structural fill should be placed in loose horizontal lifts, of not more than 8 inches in thickness, and compacted to at least 95% of the maximum dry density, as determined using test method ASTM D 1557 (Modified Proctor). At the time of placement, the moisture content of the structural fill should be, at or near, optimum. Silt Subgrade All existing HMA, base gravel and fill and/or native soil to a prescribed depth to accommodate the design section and sub base layer should be removed from areas to be paved. The native organic silt subgrade is highly moisture sensitive and should not be exposed during periods of wet weather. We recommend that exposure of the subgrade to the elements be limited to the amount of area that can by prepared during one-shift. Where the excavation has exposed soft to medium stiff organic silt soils, we anticipate that the soil surface will not support typical construction loads and will rut easily under tired vehicle traffic. We recommend that lightly loaded track mounted equipment or vehicles with oversized tires be utilized over the exposed silt subgrade to minimize disturbance and loss of stability. We also recommend that the subgrade be stabilized to adequately support construction and future traffic loads after reconstruction. Stabilization may take the form of one of the two alternatives described below: Cement Treatment: We do not anticipate that the native organic silt soils can be efficiently dried and reworked in a reasonable time without the addition of lime or cement. Since the soil is predominately silt, we expect that cement treatment will be more effective than treatment with lime. The FAA does allow cement treatment of fine grained subgrade soil to produce soil cement base (P-301). We recommend that the subject soil be sampled and checked for suitability for cement treatment as defined by FAA Advisory Circular AC 150/5370-1 OC. The cement quantity to be added is determined based on laboratory soil tests which also determine the durability and strength of the stabilized sub grade. We expect that the depth of treatment for this application will be at least 8-inches. Care must be taken to identify any existing below grade structures that that could be damaged by the cement mixing process. Usually, subgrade treated in this manner can support construction traffic after a curing period of 3 days. We understand that due to logistical reasons the reconstruction of the north portion of Taxiway B will be conducted in 2 or more phases. This will likely eliminate the economies of scale enjoyed by the assembly line method utilized in cement treatment by requiring multiple mobilizations by the soil treatment subcontractor. On the other hand because phased construction will limit the amount of subgrade exposed at anyone time to the elements, the risk of widespread subgrade damage by rainfall is reduced. ~~ __ -"TLyp",i",cal",-,s",u"b.grade ~paration using cement treatment would likely consist of the following steps: North Taxiway B-Tech Memo 4 HW A GeoSciences Inc. , April 27, 2012 HWA Project No. 2011-039-21 A. Removal of existing pavement and sub base materials down to desired depth to accommodate design taxiway section. B. Survey the exposed subgrade and collect in-place soil moisture content data utilizing a nuclear gauge. C. Apply the prescribed amount of Type I-II Portland cement on a pound per square area rate as specified in the contract documents to achieve the desired water to cement ratio of the in-place mix for the appropriate depth of mixing required. D. Mix the cement and soil using transverse. axle, single or multiple-shaft, rotary mixers to a depth not to exceed 12-inches per pass. E. Cement is applied only to an area such that the spreading, mixing, compaction, and finishing of the soil and cement can be continuous and also completed within 2 hours or less of the cement application. F. After the cement has been applied it shall be dry-mixed with the soil. Mixing is continued until the cement has been sufficiently blended with the soil to a uniform color. Soil and cement that has not been compacted and finished shall not remain undisturbed for more than 30 minutes. G. Thoroughly compact the soil cement with a vibratory, low-profile, sheepsfoot compactor. Rolling should continue until the compactor "walks out" of the lift. The surface should then be finished by rolling with a heavyweight smooth steel drum or pneumatic tire roller. H. The target density should be determined in the field by compacting representative field mixed samples of the soil-cement mixture in a 4-inch diameter mold using a 5.5-pound hammer with an twelve-inch drop (ASTM Designation: D 558). After final compaction, the soil-cement layer shall have a uniform density of not less than 95 percent of the maximum density as determined by the field test method specified above. I. At the end of each day's construction, a straight transverse construction joint is cut by cutting back into the completed work to form a true vertical face free of loose or shattered material. Soil-cement sections for large wide areas should be built in a series of parallel lanes of convenient length and width meeting the approval of the Engineer. 1. After the soil-cement has been compacted, it needs to be protected against drying by either sprinkling with water, or placement of a protective layer consisting of either 10-mil thick visqueen, concrete curing compound, or asphalt sealer. If the sprinkling method is used moisture should be applied for period of at least 7 days or until 3 days after which subbase course may be placed. Geogrid Reinforcement: Alternatively, a working surface may be constructed over the exposed native silt sub grade consisting of a biaxial or triaxial geogrid overlain by a minimum of 6-inches of compacted structural fill (P-209). The Structural fill should be placed and North Taxiway B-Tech Memo 5 HW A GeoSciences Inc. , April 27, 2012 HWA Project No. 2011-039-21 compacted in accordance with the geogrid manufacturer's requirements. At the time of placement, the moisture content of the structural fill should be, at or near, optimum. Phased construction methods are less likely to effect reconstruction costs associated with geogrid reinforcement which does not require specialized equipment to install. In addition, installation support is typically readily available from the geogrid manufacturer's local representative. Typical subgrade preparation using geogrid reinforcement would likely consist of the following steps: A. Removal of existing pavement and sub base materials down to desired depth to accommodate design taxiway section. B. Survey the subgrade surface, and depending upon soil stiffness, minimize disturbance or possibly lightly proof roll the surface. The manufacturer's representative should be contacted to observe site conditions and ensure the geogrid performance is optimized. C. The geogrid rolls are placed in position and manually rolled out over the prepared surface in the direction of travel with the appropriate amount of overlap at sides and roll ends as designated by the manufacturer (about 2 feet). D. The grid is anchored in place with small piles of aggregate prior placement of aggregate fill. In very soft areas, zip ties may be placed every 5 to 1 0 feet to maintain the overlap as directed by the manufacturer's representative. E. At the direction of the manufacturer's representative, the aggregate fill may be placed by direct dumping or by dumping from the edge of previously placed material. Spreading of material may require the use of low ground pressure (LGP) equipment if subgrade soils are very soft. F. The aggregate fill should consist of well-graded crushed rock aggregate meeting the gradation requirements specified by the geogrid manufacturer. G. The minimum lift thickness of the initial lift of aggregate fill is typically 6-inches or more over the geogrid as specified by the manufacturer. H. Compact the aggregate fill using standard methods except where soils are very soft where static instead of vibratory equipment is preferred. Where soils are very soft compaction requirements are normally reduced for the initial lift to achieve a suitable working surface from which to build the design section. NEED FOR UNDERDRAINS Although regional ground water table, or substantial seasonally perched ground water, were not observed in all of our shallow explorations of the proposed taxiway alignment, we anticipate that ground water level in the area to be high; especially during the local wet weather season. BeQause of the high fines content in the subgrade lay~r, 'Yet:xp~ct that w!lter pene!rll!ing _the surfacing could become trapped in the base course layer. Therefore, we recommend that North Taxiway 8-Tech Memo 6 HW A GeoSciences Inc. -. April 27, 2012 HWA Project No. 2011-039-21 subsurface drainage be provided below the pavement and along the edge of the taxiways and apron pavement to intercept, and prevent, possible incursion of such infiltrated water beneath the pavement areas. Failure to maintain the subgrade in a positively drained condition could lead to localized softening and loss of support for the pavement structure, possibly resulting in pre- mature pavement distress. Moreover, saturation of the subgrade with infiltrated moisture will exacerbate potential frost-heave effects and increase the rate of subgrade deterioration. CONDITIONS & LIMITATIONS We have prepared this preliminary report for the City of Renton and Reid Middleton for use in the planning and design of this project. Experience has shown that soil and ground water conditions can vary significantly over small distances. Inconsistent conditions can occur between exploration locations and may not be detected by this limited geotechnical investigation. Within the limitations of scope, schedule and budget, HW A attempted to execute these services in accordance with generally accepted professional principles and practices in the fields of geotechnical engineering and engineering geology in the area at the time the report was prepared. No warranty, express or implied, is made. The scope of our work for this phase did not include field exploration, environmental assessments or evaluations regarding the presence or absence of wetlands or hazardous substances in the soil, surface water, or ground water at this site. -----------,0-0----------- We appreciate the opportunity to provide geotechnical services on this project.
