The project site is located at 300 Rainier Avenue North, Renton, WA. A Site Location Map is shown in Figure 1 and a Site & Exploration Plan is shown in Figure 2, both are included at the end this report. We understand that the current project scope involves demolition of the existing building and construction of a new building at the same location. The new building will be similar to the existing one, that is, a single -story, wood -framed structure with a daylight basement. The existing basement opens to the east and carves into the upper portion of the onsite, east -facing slope. We anticipate relatively light building loads, and very minimal cut and fill to establish building grade. 2.0 SCOPE OF SERVICES The purpose of our investigation is to develop geotechnical recommendations regarding the design and construction of the new building. Specifically, our services included: 1. Performance of subsurface investigations by the drilling of three exploratory borings. 2. Recommendations regarding type of foundation support. 3. Evaluation of the stability of the onsite slope; impact by the proposed building and mitigation, if necessary. 4. Evaluation of the onsite grades and comment on the likelihood of onsite slope created by previous cut. 5. Recommendation regarding seismic design; evaluation of liquefaction potential and mitigation recommendations. 6. Recommendations regarding temporary slopes. 1234rpt S&EE 7. Recommendations regarding passive, active and at -rest earth pressures and coefficient of friction for the resistance of lateral loads. 8. Recommendations regarding site preparation, angles of temporary slopes, suitability of onsite soils for use as fill, types of suitable imported fill, fill placement techniques, and compaction criteria. 9. Preparation of this geotechnical report which contains a site plan, boring logs, a description of subsurface conditions, and our findings and recommendations. 3.0 SITE CONDITIONS 3.1 SURFACE CONDITIONS The project site is located at the southwest corner of Renton Municipal Airport. The site is long and narrow in the north -south direction, and is bordered to the west by Rainer Avenue North and to the east by West Perimeter Road. The site is currently occupied by a building that used to be Renton Chamber of Commerce Building. There is surface parking to the south of the existing building, and grass lawn to the north of the building. The site is located on a level bench that overlooks Renton Airport. The east side of this bench is a slope that drops about 26 feet to West Perimeter Road. The slope is relatively steep, about 75% inclination in average. At the time of this report, the slope is covered with thick vines. The slope face is relatively even, and there is no obvious sign of slope movements such as slumps or hummocky terrains. The current building is a single -story, wood -framed building with a daylight basement opening to the east. The topographic information suggests that the daylight basement is constructed with an 8-foot deep excavation in the upper half of the east slope. 3.2 GEOLOGIC INFORMATION Published geologic information (The Geologic Map of The Renton Quadrangle, King County, Washington, by D. R. Mullineaux.,1965) indicates that the site area is underlain by artificial fill which is in turn underlain by sedimentary rock with fragments of volcanic rock. The rocks are mainly sandstone, siltstone, and may locally weathered to clay. 1234rpt 2 S&EE 3.3 COAL MINE, LANDSLIDE, EROSION, AND SEISMIC HAZARDS Sensitive Areas Map published by King County indicates no landslide and erosion hazards at the project site. The map also shows that the nearest coal mine hazard area is about 1.5 miles from the site. Figure 3, which is included at the end of this report, shows that Seattle Fault is the prominent active fault closest to the site. The fault is a collective term for a series of four or more east -west -trending, south - dipping fault strands underlying the Seattle area. This thrust fault zone is approximately 2 to 4 miles wide (north -south) and extends from the Kitsap Peninsula near Bremerton on the west to the Sammamish Plateau east of Lake Sammamish on the east. The four fault strands have been interpolated from over - water geophysical surveys (Johnson, et al., 1999) and, consequently, the exact locations on land have yet to be determined or verified. Recent geologic evidence suggests that movement on this fault zone occurred about 1,100 years ago, and the earthquake it produced was on the order of a magnitude 7.5. 3.4 SUBSURFACE CONDITIONS The subsurface conditions at the site were explored by the drilling of 3 exploratory borings B-1, B-2, and B-3. B-1 and B-2 were advanced using a truck -mounted drill rig. As the grass lawn at B-3 was softened by rain at the time of drilling and could not support the drill rig, B-3 was drilled with a hand auger. The approximated exploration locations are shown on Figure 2. Details of the exploration and logs are included in Appendix A of this report. A Soil Classification Chart and Key to Logs is shown at the end of the appendix. Boring B-1 was drilled near the top edge of the east slope and found 13.5 feet of fill soil. The fill consists of loose to medium dense silty sand and gravel, and is underlain by a medium stiff silt. This silt contains trace organics and has the appearance of alluvial deposits. We believe that a swale or creek was once occupied the area. A hard silt is found below the alluvial soil. This silt becomes very hard below the depth of 24 feet and the auger was refused at 25 feet. Based on our experience with the subsurface condition in the region, we believe this hard silt represents the upper, weathered portion of a siltstone. Boring B-2 was drilled near the western site boundary. The boring encountered 7 feet thick of very dense sand at the ground surface. The sand is underlain by a medium dense to dense silty sand that has the appearance of an alluvial soil. Similar to the condition at B-1, the alluvial soil is underlain by a hard silt that is likely a siltstone. B-2 also encountered very hard silt at a depth of 24 feet and the silt became so hard that the auger could not be advance beyond the depth of 25 feet. 1234rpt 3 S&EE Boring B-3 encountered about 10 feet thick of medium dense.to dense sand. Like B-1 and B-2, boring B-3 found alluvial -like silt below the upper sand. This silt is very stiff and prevented drilling below a depth of 10.5 feet. Borings B-1 and B-3 did not encounter any groundwater, but B-2 encountered groundwater at a depth of 8.5 feet. The subsoils at B-1 were moist and not wet, and the alluvial soil at B-3 was moist to wet. This information indicates that a perched groundwater table is present over the relatively impervious alluvial silt. We further believe that the depth of this perched groundwater table will vary with season and precipitation. All soil samples were screened by a PID (photoionization detector) which did not detect any organic vapor. Based on our experience with the subsoils, it is our opinion that the alluvial soils at depths of 7 to 13.5 feet are slightly corrosive. 4.0 ENGINEERING EVALUATION OF SLOPE STABILTY Based on our understanding of the soil and groundwater conditions underlying the site, and our estimate of the soil parameters, we have conducted slope stability analyses using the computer program STABL5M. Both steady state and dynamic/seismic loading conditions were considered. The standard engineering practice considers the stability of a slope to be acceptable if it demonstrates a factor of safety of at least 1.5 and 1.1 for static and seismic conditions, respectively. A factor of safety is defined as the summation of resisting forces divided by the summation of driving forces. Our evaluations show a factor of safety of 1.43 and 0.78 for static and seismic conditions, respectively. The graphic presentations of these evaluations are shown in Appendix B at the end of this report. I234rpt 4 S&EE 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 GENERAL 1. Based on the boring data, we believe that the steep slope at the east side of the site is a filled slope and the fill was probably placed at the time of road (Rainier Ave N) construction. 2. We believe that the daylight basement of the existing building is founded on the competent alluvial soils that include medium to very stiff silt and medium dense to dense silty sand. On the other hand, the western, single -story portion of the building is founded on competent medium dense to very dense sand or silty sand. We further believe that the new building can be supported on conventional spread footings founded on the same soils at similar depths as the existing building. 3. Our slope stability evaluations show that the onsite, east -facing steep slope is relatively stable at steady state (factor of safety = 1.43), but has a high risk of sliding during strong earthquake (factor of safety = 0.78). Also, the slope stability is not affected by the building loads as they are supported on competent soils and the building loads are away and outside the potential slide plane. Details of our recommendations are presented below. 5.2 FOUNDATION SUPPORT We recommend that the new building be supported on conventional spread footings. The followings parameters are recommended for spread footing design and construction. Allowable Bearing Loads: Footings can be designed with an allowable bearing pressure of 3,000 pounds per square foot (pso. This value includes a factor of safety of at least 3, and can be increased by one-third for wind and seismic loads. Footing Construction: Prior to re -bar and concrete placement, all footing bearing surfaces must be cleaned of loose soil cuttings. Any softened and loosened soil encountered at footing subgrade should be over -excavated, and the over -excavation should be backfilled with concrete or compacted crushed rock. The latter should be approved by an engineer from our office prior to use. 1234rpt 5 S&EE All footing bearing surfaces should be inspected by a geotechnical engineer from our office prior to concrete placement. Our engineer will confirm the bearing capacity of the subgrade soils, and provide recommendations regarding over -excavation, if necessary. Settlement: Interior column footings designed in accordance with the above recommendations are expected to experience approximately 1/2 inch of settlement. Continuous wall footings should experience settlement of about 1/4 to 1/2 inch. Differential settlement between adjacent footings is expected to be about 1/4 inch. The settlement will occur rapidly, essentially as the loads are applied. Lateral Resistance: Lateral resistance can be obtained from the passive earth pressure against the footing sides and the friction at the contact of the footing bottom and bearing soil. The former can be obtained using an equivalent fluid density of 250 pounds per cubic foot (pcf), and the latter using a coefficient of friction of 0.5. These values include a safety factor of 1.5. Frost Protection and Minimum Width: All exterior footings should be founded at least 12 inches below the adjacent finished grade to provide protection against frost action, and should be at least 18 inches in width to facilitate construction. 5.3 LATERAL EARTH PRESSURES ON PERMANENT RETAINING WALLS Lateral earth pressures on permanent retaining walls, underground vaults or utility trenches/pits, and resistance to lateral loads may be estimated using the recommended soil parameters presented in the following table. .� � .. .... a •Y .. . � .. ;. . >;. Equivalent FluidUnit Weighf.(PCF)° of M a�. Friction' at -Base F d , Active'.At-rest. ` Passive Structural fill and 40 50 250 0.5 native soils Note: Hydrostatic pressures are not included in the above lateral earth pressures. 1234rpt 6 S&EE The at -rest case applies to unyielding walls, and would be appropriate for walls that are structurally restrained from lateral deflection such as basement walls, utility trenches or pits. The passive earth pressure and coefficient of friction include a safety factor of 1.5. The active case applies to walls that are permitted to rotate or translate away from the retained soil by approximately 0.002H to 0.004H, where H is the height of the wall. SURCHARGE INDUCED LATERAL LOADS Additional lateral earth pressures will result from surcharge loads from floor slabs or pavements for parking that are located immediately adjacent to the walls. The surcharge -induced lateral earth pressures are uniform over the depth of the wall. Surcharge -induced lateral pressures for the "active" case may be calculated by multiplying the applied vertical pressure (in psf) by the active earth pressure coefficient (Ka). The value of Ka may be taken as 0.3. The surcharge -induced lateral pressures for the "at -rest" case are similarly calculated using an at -rest earth pressure coefficient (Ko) of 0.5. For surcharge loads that are not adjacent to the wall, the induced lateral earth pressure will depend on the magnitude of the surcharge and the distance from the wall. Such induced lateral load can be estimated using the equations shown on Figure 4 The slope -induced lateral earth pressure can be accounted for by increasing the effective height of the wall by one-half the slope height. The traffic -induced lateral earth pressure can be accounted for by increasing the effective wall height by 2 feet. SEISMIC INDUCED LATERAL LOADS For imbalanced, seismic induced lateral loads, the dynamic force can be calculated using the following equation. Pe = 1 OH , where Pe = uniform pressure in psf H = wall height in feet BACKFILL IN FRONT OF RETAINING WALLS Backfill in front of the wall should be structural fill. The material and compaction requirements are presented in Section 5.4 of this report. The density of the structural fill can be assumed to be 130 pounds per cubic feet. 1234rpt 7 S&EE BACKFILL BEHIND RETAINING WALLS Backfill behind the wall should be free -draining materials which are typically granular soils containing less than 5 percent fines (silt and clay particles) and no particles greater than 4 inches in diameter. The backfill material should be placed in 6 to 8-inch thick horizontal lifts and compacted to at least 90 percent of the maximum density in accordance with ASTM D-1557 test procedures. In the areas where the fill will support pavement, sidewalk or slabs, the top four (4) feet of the backfill should be compacted to at least 95 percent of the maximum density. Care must be taken when compacting backfill adjacent to retaining walls, to avoid creating excessive pressure on the wall. DRAINAGE BEHIND RETAINING WALLS Rigid, perforated drainpipes should be installed behind retaining walls. Drainpipes should be at least 4 inches in diameter, covered by a layer of uniform size drain gravel of at least 12 inches in thickness, and be connected to a suitable discharge location. An adequate number of cleanouts should be installed along the drain line for future maintenance. 5.4 STRUCTURAL FILL The structural fill materials should meet both the material and compaction requirements presented below. Material Requirements: Structural fill should be free of organic and frozen material and should consist of hard durable particles, such as sand, gravel, or quarry -processed stone. The on -site sandy soils are suitable for structural fill. The material should be moisture -conditioned to +/- 2% from their optimum moisture contents prior to use. Suitable imported structural fill materials include silty sand, sand, mixture of sand and gravel (pitrun), and crushed rock. All structural fill material should be approved by our geotechnical engineer prior to use. Placement and Compaction Requirements: Structural fill should be placed in loose horizontal lifts not exceeding a thickness of 6 to 12 inches, depending on the material type, compaction equipment, and number of passes made by the equipment. Structural fill should be compacted to at least 95% of the maximum dry density as determined using the ASTM D-1557 test procedures. 1234rpt 8 S&EE 5.5 SITE DRAINAGE The site surface should be graded so that surface water is directed away from the structural areas. Standing water should not be allowed. Final site grades should be sloped away from the building unless the area is paved, or yard drains installed to collect surface runoff. Onsite infiltration of storm water is not recommended as the water would incur negative impacts on the stability of the steep slope. 5.6 SLAB -ON -GRADE All slabs can be soil supported. We envision that the soil at the subgrade will be disturbed and loosened by construction activities at the time of slab construction. We therefore recommend that the subgrade be re - compacted prior to pour. Any wet and loose areas should be over -excavated and backfilled with structural fill. Assuming that the slab subgrade is prepared per recommendations presented above, a subgrade reaction modulus of 100 pci (pounds per cubic inches) can be used for slab -on -grade design. We recommend that slab -on -grade be underlain by a 15 mil vapor barrier over at least 4-inch thick free - draining gravel. 5.7 TEMPORARY AND PERMANENT EXCAVATIONS Temporary cuts less than 4 feet in depth can be sloped at 1 H:1 V (Horizontal to Vertical) or flatter; temporary cuts deeper than 4 feet should be sloped at 1.5H:IV. The contractor should note the following recommendations. 1. A perched groundwater table may be present near the bottom of the cut. Therefore, temporary cut should be continuous from the top to bottom with no vertical bank at the toe of the cut. A vertical bank will adversely impact the stability of the slope if groundwater seepage occurs. 2. The slope face should be protected from weather using visqueen. All permanent slopes should be no steeper than 2H:1 V. Water should not be allowed to flow uncontrolled over the top of any slope. Also, all permanent slopes should be seeded with the appropriate species of vegetation to reduce erosion and maintain the slope stability. 1234rpt 9 S&EE 5.8 SEISMIC CONSIDERATIONS We recommend that Site Class C as defined in the 2009 IBC be considered for the seismic design. Due to the presence of firm soils below the perched groundwater table, liquefaction potential is negligible. 5.9 ADDITIONAL SERVICES We recommend the following our additional services during the design and construction of the project. 1. Review design plans to confirm that our recommendations are properly interpreted and utilized in the design. 2. Monitor excavation. We will confirm the stability of the excavations, and provide recommendations regarding dewatering and sidewall stabilization, if needed. 3. Monitor foundation subgrade preparation. We will confirm the bearing capacity of the subgrade soils, and assist the contractor in evaluating the protection and over -excavation requirements, if any. 4. Monitor the placement and compaction of structural fill. We will confirm the suitability of the fill materials, and assist the contractor in meeting the compaction requirements. 5. Monitor the installation of subsurface drains. We will confirm that these drains are installed in accordance with our recommendations. 6. Monitor site drainage and erosion control. 7. Other geotechnical issues deemed necessary. 1234rpt 10 S&EE 6.0 CLOSURE The recommendations presented in this report are provided for design purposes and are based on soil conditions disclosed by field observations and subsurface explorations. Subsurface information presented herein does not constitute a direct or implied warranty that the soil conditions between exploration locations can be directly interpolated or extrapolated or that subsurface conditions and soil variations different from those disclosed by the explorations will not be revealed. The recommendations outlined in this report are based on the assumption that the development plan is consistent with the description provided in this report. If the development plan is changed or subsurface conditions different from those disclosed by the exploration are observed during construction, we should be advised at once so that we can review these conditions, and if necessary, reconsider our design recommendations. 1234rpt 11 S&EE an fit'• _ t ,� IM N\ Y o Newcastle y' ;o Soal Creek r l < { l_ + `, •, ~• f)enclel�cn St -40 ` .r1 3mh Sl m S Bang oRwefton-Bduleva`d Pa, k. 4, a° �, � � \` .ci-e ,. __ � � �1 �� ti � 'd T •t aSuanRa:,� a '�Asj.�- t, oBry'r,1AaHr•Skyway ��� ► a� r• i r �j�y `rj30D as �t\r Ave N.

B-1 and B-2 were advanced using a truck -mounted drill rig. As the grass lawn at B-3 was softened by rain and could not support the drill rig, Boring B-3 was drilled with a hand auger. A representative from S&EE was present throughout the exploration to observe the drilling operations, log subsurface soil conditions, obtain soil samples, and to prepare descriptive geologic logs of the exploration. Soil samples were taken at 2.5-foot and 5-foot intervals in general accordance with ASTM D-1586, "Standard Method for Penetration Test and Split -Barrel Sampling of Soils" (1.4" I.D. sampler). The penetration test involves driving the samplers.18 inches into the ground at the bottom of the borehole with a 140 pounds hammer dropping 30 inches. The numbers of blows needed for the samplers to penetrate each 6 inches are recorded and are presented on the boring logs. The sum of the number of blows required for the second and third 6 inches of penetration is termed "standard penetration resistance" or the "N-value". In cases where 50 blows are insufficient to advance it through a 6 inches interval the penetration after 50 blows is recorded. The blow count provides an indication of the density of the subsoil, and it is used in many empirical geotechnical engineering formulae. The following table provides a general correlation of blow count with density and consistency. DENSITY (GRANULAR SOILS) N-value < 4 very loose 5-10 loose 11-30 medium dense 31-50 dense >50 very dense CONSISTENCY (FINE-GRAINED SOILS) N-value < 2 very soft 3-4 soft 5-8 medium stiff 9-15 stiff 16-30 very stiff >30 hard All soil samples were screened by a PID (photoionization detector). The readings are presented on the boring logs. After drilling, borings B-1 and B-2 were backfilled with bentonite chips and the asphalt surface at B-2 was patched with quick set concrete. Boring B-3 was backfilled with the onsite soil. The boring logs are included in this appendix. A chart showing the Unified Soil Classification System is included at the end of this appendix. 1234rpt S&EE m —0 a m m a a� 3 O O c me U U E U 1p fn Surface Condition: Bare BORING B-1 3, 1°10 0 3 i i Sm - 3 inches crushed rocK at ground surtace 3 I I ' Brown silty fine sand (moist)(loose to medium dense)(probable fill) I I ' o 8 1 18 9 10 10 6 ' 0 ; 7 ' 18 trace fine gravel at 5 feet 8 ; 8 10 , 0 318 4 i10 3 I I I i I I I 10' 0 3 ' 18 ' 3 3 i 6 GP Dark brown fine to medium gravel, trace tree debris (moist)(medium dense)(probable fill) I I I 0 6 7� I I ML Bluish gray silt, trace organics (moist)(medium stiff) 15 , o 2 : 18 ' 2 10 5 I , I I I I ML Gray silt (relatively dry)(hard)(possible siltstone) o 114 12 sore • 112 I I I ' I I I I ' I .20,------'------ (Boring log continues on Figure A-1b) Client: SRG Partnership, Inc.

Washington 98004 Tel. 425.869.9448 800.835.0292 Fax 425.869.1190 Project No: 0015.00021.000 Page 1 of 4 The City hired Roth Hill to complete an alternatives analysis to research and study options associated with the possible elimination of the existing Airport Lift Station located on the west side of the City of Renton Airport along W. Perimeter Road. The scope for the project included evaluating possible gravity sewer options to allow the existing lift station to be eliminated and the existing effluent flow to be routed to the King County trunk main running along the northern part of the airport property. The analysis included evaluating possible construction routes, construction methods, construction costs, and potential impacts to the businesses that regularly use W. Perimeter road and maintain operations along the west side of the airport runway. BACKGROUND The City of Renton currently operates sanitary sewer collection and conveyance systems within the City of Renton Airport in the western portion of the City, bordered by Taylor Place and Lind Avenue to the west, and the airport runway to the east; and from Airport Way to the south and 7th Street to the north, as shown in Figure 1. This portion of the City's system includes a sewer lift station on the Airport property within the security fence. The existing lift station was constructed in its current location in 1987 and the force main discharges into the existing gravity sewer to the southwest of the station in Rainier Avenue. The existing service area served by the Airport Lift Station abuts the service area for Skyway Water & Sewer District (Skyway). A portion of the service area supported by Skyway to the north of the Airport Lift Station service area is located within the City of Renton city limits, although the City has not been able to provide sewer service to this area. The City would like to have the ability to provide gravity service to not only the current area served by the existing airport lift station, but also the area within the City of Renton that is currently served by Skyway. In addition, there is another existing lift station at the intersection of W. Perimeter Road and the western entrance to the airport property from Rainier Avenue. This existing lift station is currently operated by Renton Airport Staff and discharges into the Skyway sewer system. The eastern edge of the service area for the airport lift station consists of sewer mains F:W15t00021.000Wltematives AnalysistDC_091112_ejw_memo_Airport LS Abandonment Analysis.docx Dave Christensen September 27, 2012 Page 2 located in W. Perimeter Road. Any potential gravity sewer option would consist of installing new gravity sewer in W. Perimeter Road flowing north to the existing King County trunk sewer. In addition to the normally expected utilities currently in W. Perimeter Road, -the City of Renton has installed the Black River Culvert under the road. The Black River Culvert consists of an existing 60 inch diameter concrete culvert in some places along the road and a 7 foot by 5 foot or 8 foot by 5 foot box culvert in other places. GRAVITY SEWER ANALYSIS The City of Renton was interested in a potential gravity sewer option to allow for the abandonment of both the existing airport lift station and the lift station currently operated by Airport Staff. The City asked Roth Hill to analyze potential routes for the possible gravity sewer from the existing station on W. Perimeter Road to the King County trunk sewer main that runs across the northern end of the airport runway, approximately 4,000 feet north of the lift station. To facilitate the gravity sewer analysis, a topographic survey was completed from 100 feet south of the existing lift station to the location of the King County trunk sewer crossing. The survey was bounded on the west by the ROW for Rainier Ave and on the east by the airport security fence. The goal of the gravity sewer analysis was to determine if there was adequate room within the limits of W. Perimeter Road for the new gravity sewer between all of the existing utilities, evaluating both horizontal and vertical alignment and clearances. Additionally, the analysis needed to determine if the new gravity sewer could be constructed around the existing Black River culvert. Based on the topographic survey and research of the existing utilities, it was determined that there was sufficient room for a new gravity sewer within W. Perimeter Road and that the main could be constructed around the existing Black River culvert. The preliminary proposed plan and profile for the gravity sewer alternative can be found in the attached drawings labeled C1 through C9. The preliminary route of the proposed gravity sewer would need to be installed on both the west and east side of W. Perimeter Road as it traveled north from the existing lift station to the King County trunk sewer in order to avoid existing utilities and the Black River culvert. Based on the layout shown in the attached drawings, the new gravity sewer would be installed anywhere from 10 feet to 28 feet deep and would require approximately 23 manholes. The proposed sewer would also require 4 crossings beneath the Black River culvert. It was assumed that these crossings would be accomplished using trenchless technology such as pipe ramming or auger boring. Once the preliminary route for the proposed gravity sewer was determined, an onsite meeting with the City was conducted to review the alternative. Based on the anticipated depth of the proposed sewer and the number of required crossings of the Black River culvert, we looked at the possibility of moving the proposed sewer further east inside of the security fence for the airport property. The sewer alignment on the airport property can be seen on Sheets C5 through C9 on the attached drawings. Moving the sewer further into the airport property provided two main advantages over the preliminary route, 1) the main could be installed at a much shallower depth and 2) the new main would only require one crossing of the Black River culvert. The disadvantage of moving the proposed gravity sewer further into the airport property was that there are several buildings that are very close to where the new main would need to be installed and there is evidence of existing utilities that would need to be relocated during construction.

These.estimates are roughly twice the cost of rehabilitating the existing lift station based on City cost data from the rehabilitation of similar sized stations within the City. Although there would be savings to the City in reduced operations and maintenance costs by eliminating the lift station, the magnitude of these savings would not be significant enough to justify the initial difference in constructions costs. Due to the higher cost of installing a gravity sewer to abandon the existing lift station and the potential construction impacts to the airport property and local businesses, the City has decided to forego the gravity sewer option and to revert to rehabilitating the existing airport lift station. AIRPORT LIFT STATION PRELIMINARY ANALYSIS Once it was determined that the gravity sewer alternative was no longer cost effective, the City made the decision to rehabilitate the existing airport lift station. To initiate this process, a meeting was held with the City of Renton airport staff to summarize the results of the gravity sewer analysis and to discuss possible locations for a new sewer lift station. The goal of the sewer department is to install the new sewer lift station outside of the security fence for the airport. This will facilitate easier access for maintenance and operation of the station. Based on the discussions with the City's airport staff and a walkthrough of the potential lift station relocation site, it was determined that the best location for the new lift station would be on the west side of W. Perimeter Road approximately 200 feet south of the existing lift station location. The grassy area west of the roadway will allow for the installation of the new lift station facility including a 6 foot by 8 foot control building, a 12 foot diameter combined wet well/overflow structure, and a small generator. The site will be designed to include a roll-on curb so that sewer maintenance staff can get any maintenance vehicles off of the roadway enough to keep two travel lanes open when work is occurring at the station site. The site will require a small retaining structure on the hillside to the west of the new lift station towards Rainier Avenue. A preliminary layout for the new lift station can be seen in the attached drawing LS1. In addition to looking at the potential site for the new lift station, Roth Hill prepared Figure 1 showing the approximate service area for the new lift station. This figure was given to the City to have the planning department review for any potential increase in population density within the service area. The City's planning department determined that the area served by the existing, and subsequently the new lift station will not have its zoning changed. As the project moves forward into the lift station design phase, several factors will be further analyzed and incorporated into the lift station design, including the service area, total anticipated peak flow rates from residential and commercial areas (including any modifications to the airport master plan), and how to construct the station to handle initial low flows as compared to final total flows.

Respectfully, Dave Honeysett Project Manager Potelco, Inc 253-677-7726 Accepted Print Name Date PROPERTY I CLIENT NAME: Former Renton Chamber of Commerce Building FUNDING AGENCY: Community Economic Revitalization Board Project Applicant: City of Renton, Renton Municipal Airport Contact Person: Ben Dahle Address: 616 W Perimeter Rd, Unit A City, State: Renton Zip: 98057 County: King Phone/ FAX: 425.430.7476 E-Mail: BDahIeCa)Rentonwa.gov Funding Agency: Organization: Community Economic Revitalization Boar Address: PO Box 42525 City, State: 01ym0a, WA Zip: 98504-2525 Phone: (360) 725-3161 ® Provide a detailed description of the proposed project: The former Renton Chamber of Commerce Building is proposed for replacement utilizing funds from the Community Economic Revitalization Board, Economic Development, Micro Community Revitalization and Community Revitalization grant program. The structure was originally constructed in 1961, with significant alterations of the building taking place in 1970 (see below). The wood -framed structure is outdated and unsuited for the proposed re -use plan as a aerospace training facility. The present proposal would utilize the current property to build a new structure for educational use by Renton Technical College, operating as Renton Aerospace Training Center. No new property or right-of-way is necessary for the proposal. ® Describe the existing project site conditions: The proposed building project is located on City of Renton Property in King County, Washington. Specifically, it is located in the NE'/4'/ of the NW '/4 of Section 18, Township 23 North, Range 5 East, Willamette Meridian, on the Renton, WA (1989), 7.5-minute U.S. Geological Survey (USGS) quadrangle (Below). The project is located in a highly developed commercial and industrial use area on a 30 foot steeply cut terrace overlooking Renton Airport and a former, in -filled embayment of Lake Washington where the Black River and Cedar River conflux (Figures 1-2). The property consists of the two-story former chamber building, a large paved parking lot (Figures 3-4) and a small pocket park at the southern end of the property which is not proposed for any re -use. A small amphitheatre was removed previously from the park. The building footprint consists of a large excavation for a daylight basement, allowing for only a single story above the present, surrounding, ground surface. The building is located on a formerly undulating terrace landform composed of sandy glacial drift. Logging, farming and industry have dramatically altered the landform as is illustrated in Figures 1-2 and through subsurface excavations at the property. The U.S. Army was largely responsible for this alteration when, for use in the WWII war effort, they filled in the present configuration of the Renton Airport to build B-29 Bombers. The present project location was cleared and leveled, while a large portion of the lower airport property, including the former course of the Black River, was filled with materials from the upper terrace and hillside itself. The building at 289 Perimiter Road/300 Rainier Avenue South was constructed in 1961 as the original Renton Chamber of Commerce building. The building was designed by Johnston -Campanella AIA + Associates of Renton, Washington. The building was constructed as a single story 56-foot by 40-foot structure on the southwestern edge of the Renton Municipal Airport. It was reportedly constructed at a very low cost, using inexpensive materials and construction techniques. However, its design is distinctive, and representative of mid-century building styles. The distinctive roofline above the east and west elevations mimic the sawtooth roofline of the WWII era Boeing manufacturing plant that it faces to the east, across the airport runway. And the north and south entries originally saw parabolic rooflines. Unusual four -light diamond windows, with one aluminum casement opening provide light on the west, street -side, fagade, beneath each gable peak. The Chamber of Commerce building was originally designed with an expansive observation deck that spanned the entire east facade and most of the north and south facades, accessed by two sets of sliding doors on the east facade, which capitalized on the views of the airport. Because of structural deficiencies, the observation deck was removed and the sliding doors were replaced with vinyl sash circa 2002. In the 1970s, a major addition was built at the primary (south) entry, which highly modified the building's design and materialsAlthough the building exhibits some distinctive characteristics of a mid-century municipal building, it is not recommended eligible for listing in the NRHP because it lacks integrity of design, materials, workmanship, and feeling. ® Describe the proposed ground disturbing activities: Ground alterations would likely be contained to the previously disturbed soils associated with the construction phases of the extant structure. ® Check if building(s) will be altered or demolished. If so please complete a DAHP Determination of Eligibility "EZ2 form" using our on-line Historic Property Inventory Database for each building affected by the proposed project. 41 H E N a — Approximate Project Site AL J.; T N Figure 1.
