The subject property is considered to be part of Phase IV of the Longacres Office Park (“LOP”)and is subject to the 2003 Development Agreement (Exhibit 19)and a 2006 Strander Agreement (Exhibit 20).The parcels are located within Phase IV of LOP and the development agreement is in effect until February 21,2023.According to the development agreement,development regulations include (a)zoning,land division,and development standards;(b) environmental rules and policies,including (but not limited to)SEPA;(c)Comprehensive Plan policies;(d)policies, regulations,standards,and methods applicable to the development of land that are incorporated by reference in the Renton Municipal Code;(e)surface water management regulations;and (f)other City ordinances governing the development of land up to and including adopted Ordinance No.4877.Environmental analysis of development of 2.5 million square feet under the LOP Site Plan was conducted by the City of Renton pursuant to the Washington State Environmental Policy Act (“SEPA”).A Draft Environmental Impact Statement (“DEIS”)for the LOP Site was issued in August,1994:the Final Environmental Impact Statement (“FEIS”)was issued in March,1995.Phase IV was proposed to consist of development of office or light industrial space as permitted under the Employment Area (EA) land use designation and Commercial Office (CO)zoning,with support and utility facilities.Phase IV will be developed with multiple buildings and associated parking,roadways,and pedestrian walkways. The adjacent Renton parcels are zoned CO to the north and south with Heavy Industrial (IH)to the east (across Oakesdale Ave SW).The property is bordered on the west by Burlington Northern Railroad,located within Tukwila City Limits.To the south are Longacres Business Center Phase I and the Federal Reserve Bank and to the north is BOW Lake Pipeline right-of-way,within a 30-foot wide tract,followed by undeveloped commercial properties. The site is currently undeveloped and covered with a moderate growth of brush,weeds and grass.The parcels were previously developed with a horse racing track and associated buildings and infrastructure.The aboveground structures have since been demolished but remnant paved roadways and foundations are still visible across the property.There are no existing buildings on the site.There are 53 significant trees that intermittently appear on parcels 088670-0150,-0190,while parcels -0090 and -0100 have very few existing trees.The applicant is proposing to retain seven (7)significant trees.Native tree preservation would occur along project perimeter buffers.The new landscaping improvements would be integrated with the existing and would include drought tolerant plant materials.In addition,onsite there is also a paved/gravel road that runs parallel to SW 27th St across the parcels from Oakesdale Ave SW,and north along parcel no.088670-0190,which will be removed during site development. The topography of the property varies from parcel to parcel but is relatively flat with gentle slopes to the northeast with establishing grade changes of less than six feet.Based on the topographic map,the elevation of the property is approximately 20 to 22 feet in elevation (Exhibits 5,6,8 &10). A Confirmation of Environmental Setting Report,prepared by Terracon Consultants,Inc.on August 14,2015,did not identify a wetland area,streams,lakes,or critical habitats on or adjacent to the property based on a review of third party work and online resources (Exhibit 16).In addition,a flood insurance rate map (FIRM)for the Property (see attached)identifies a 100-year floodplain,Zone AE,in close proximity to the northwestern Property boundary,which may extend onto the Property.The base flood elevation shown on the FIRM for Zone AE is 16 feet above mean sea level.Southern portions of the site are located within Zone X,outside the 100-year or 500-year flood zones.The ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report -LONGACRES BUSINESS CENTER PHASE II LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 3 of 10 nearest habitats are mapped on the Green River approximately 1,100 feet to the west and a small creek approximately 800 feet to the east and south.These habitats are associated with bull trout and salmon.A wildlife corridor was identified through the Environmental Impact Statement (EIS)which extended through the central portion of the Property (Tract C).The report noted that the corridor was originally designated to provide for stormwater treatment,wetland mitigation and wildlife habitat;however no easements or deed restrictions were present within the corridor.The site also contains High Seismic Hazards. The proposal includes 1,063 surface parking stalls.Along the west and east borders of the site,a 30-foot setback to the property line is observed.This setback accommodates a 20’wide Green River Valley Wildlife Habitat Corridor as well as a 10-foot wide perimeter landscaping buffer.Along the north property line,a minimum 20-foot wide perimeter landscaping buffer is observed.Along SW 27th St,a 15 to 115-foot street frontage buffer is provided.An additional 45-foot wildlife open space within several utility easements is also provided.Beyond the easements,a final 10-to 15-foot wide landscaping strip screens the large surface parking lot (Exhibit 5). This project proposes to construct a drainage system with a new network of underground pipes,catch basins,curbs and gutter,to collect surface water runoff throughout the site and direct it to a detention wetpond within Tract B for water quality treatment and detention.Runoff from the site will be discharged to the north,into the previously developed Longacres Office Park drainage system within the Boeing property.From the Longacres Office Park drainage system,the drainage flows into Springbrook Creek and ultimately the Duwamish River.Construction is anticipated to be completed and occupied by June 2017. The applicant has submitted a Drainage Report,Traffic Impact Analysis,Confirmation of Environmental Setting Report,Geotechnical Engineering Report,and a Supplemental Site Exploration with the subject application.Staff received no comments from the public,Muckleshoot Indian Tribe Fisheries Division,or any other agency.

The site can be characterized as relatively flat with gentle slopes to the north with established grade changes of less than six feet. The soils onsite generally consist of three to seven inches of topsoil overlying 1 to 6 feet of medium dense to dense inorganic fill material overlying alluvial silts and sands in 6 of the 13 test pits.The fill soils varied and consisted of sand,sand with silt,silty sand with gravel,gravel,and crushed rock.In general,the fill was relatively thin,ranging from one to two feet thick.Deeper fills were discovered where abandoned utilities were found.Where no fills were present,loose to medium dense alluvial silt,silty sand with silt,and relatively clean sand were present.Cone penetration tests (CPTs)data indicated highly variable interbedded alluvial soils composed of silts,clays,and silty sand layers are present to a depth of 15 to 22 feet followed by medium dense to dense silty sand and sand to the termination depths of the CPTs,70 feet.Additional site explorations,via six soil test borings drilled to depths of 60 feet,using mud rotary drilling methods,indicate very loose and soft silty sand and silt alluvium to a depth of about 23 feet followed by medium dense to occasionally dense dark gray to black sand alluvium.Evidence of groundwater was observed at depths of 5 to 11 feet below current surface grades. The Geological Map of the Renton Quadrangle,Washington,by DR.Mullineaux (1965),maps the site as Alluvium (Qaw).The soils observed onsite are classified as Newberg Silt Loam,Woodinville Silt Loam,and Urban Land by the United States Department of Agriculture Natural Resources Conservation Service (NRCS), formerly the Soil Conservation Service. The applicant submitted a Geotechnical Report prepared by Terra Associates,Inc.,dated August 18,2015 (Exhibit 11).The report states that the subsurface conditions were explored by excavating nine (9)soil test pits to depths of 10.5 to 13 feet below current site grades.In-Situ Engineering,under subcontract with Terra Associates,Inc.,performed 8 cone penetration tests (CPTs)to depths of 70 feet.More data was achieved by excavating four (4)test pits to depths of 14.5 to 17 feet below current site grades in the proposed stormwater tract (Tract B).A Supplemental Site Exploration by Terra Associates,Inc.,dated August 31,2015 ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report LONGACRES BUSINESS CENTER PHASEII LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 5 of 10 included six (6)soil test borings drilled to depths of 60 feet below current site grades (located within the footprints of the proposed buildings).The soils observed at the site contain a significant amount of fines which would be difficult to compact as structural fill when too wet.Over most of the site with the existing slope gradients,these soils would have a slight potential for erosion when exposed.Therefore the site is considered a low erosion hazard area.Erosion protection measures would include perimeter silt fencing to contain erosion onsite and cover measures to prevent or reduce soil erosion during and following construction. Based on the soil and groundwater conditions onsite,the site would be mapped as a High Seismic Hazard1 (SH).The impact to the site should liquefaction occur would be in the form of surface subsidence or settlement.Estimated total potential settlement by the geotechnical engineer was in the range of two to four inches.In the geotechnical engineer’s opinion,this amount of settlement would not structurally impact the building but could result in damage of a cosmetic nature. The existing site consists of 2.14 acres of impervious area and 13.82 acres of pervious area.The developed site hydrology will increase the amount of impervious area by approximately 8.93 acres to 11.07 acres (69%) and the pervious and landscaping would be 4.89 acres following construction. The geotechnical report concludes that development of the site as proposed is feasible from a geotechnical engineering standpoint.The primary geotechnical concern at the site is the presence of compressible soil strata susceptible to consolidation under the planned building loads.The heavier three-story and four-story buildings could be mitigated from potential settlement-related impacts by supporting the structure on augercast piles or on spread footings,bearing on ground conditions improved by installation of rammed aggregate piers/stone columns.Augercast piles,if used,should be advanced to obtain support in the medium dense sand alluvium indicated to be present at depths of 30 to 35 feet.If grading activities take place during the winter months,clean granular material for use as structural fill and backfill should be imported.Alternatively,stabilizing the moisture in the native and existing fill soils with cement or lime can be considered. Overall the submitted geotechnical report provides recommendations for geologic hazards,site preparation and grading,preload/surcharge,excavation,foundations,slab-on-grade construction,lateral earth pressures for wall design,drainage,utilities,and pavements (Exhibit 9).Staff recommends as a SEPA mitigation measure that project construction is required to comply with the recommendations found in the Geotechnical Engineering Study and Supplemental Site Exploration prepared by Terra Associates,Inc.(dated August 18,2015 and August 31,2015,respectively). The applicant will be required to design a Temporary Erosion and Sedimentation Control Plan (TESCP). Mitigation Measures:Project construction shall be required to comply with the recommendations found in the Geotechnical Engineering Study and Supplemental Site Exploration prepared by Terra Associates,Inc. (dated August 18,2015 and August 31,2015,respectively;Exhibits 11 &12). Nexus:State Environmental Policy Act (SEPA)Environmental Review,RMC 4-3-050 Critical Areas Regulations,and RMC 4-4-060 Grading,Excavation,and Mining Regulations. 2.Water a.Wetland,Streams,Lakes Impacts:A Confirmation of Environmental Setting Report,prepared by Terracon Consultants,Inc.(dated August 14,2015;Exhibit 16)was submitted with the project application materials.Information reviewed by Terracon was limited to available online resources and/or prior reports.The site is within the Black River and 1 High Seismic Hazard (SH):Areas underlain by soft or loose,saturated soils.These soils generally have site classifications E or F, as defined in the International Building Code,2012 (RMC 4-3-050G.5.d.ii). ERC Report LUAS-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report LONGACRES BUSINESS CENTERPHASE II LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 6 of 10 specifically the Springbrook Creek drainage basin.This site is located generally at the high point of the area topography and the National Wetland Inventory fNWl)map did not identify a wetland area on or adjacent to the property.Freshwater Forested/Shrub wetlands and Freshwater Emergent wetlands were identified on the east-,west-and south-adjoining properties respectively,approximately 80 to 300 feet from the Property boundary.A wetland area was identified approximately 250 feet south-southeast of the property.A report entitled “Longacres Office Park,Surface Water Management Project,Conceptual Wetland Mitigation Plan” prepared by Shapiro and Associates,Inc.(dated August 1998)was prepared for a 164-acre parcel which included the subject property.According to the report,the site does not contain a wetland area.In addition, a flood insurance rate map (FIRM)for the Property identifies a 100-year floodplain,Zone AE,in close proximity to the northwestern Property boundary,which may extend onto the Property.The base flood elevation shown on the FIRM for Zone AE is 16 feet above mean sea level.Southern portions of the site are located within Zone X,outside the 100-year or 500-year flood zones.As such,Terracon infers that the information may be subject to change following a current review by a wetlands professional,if required. Terracon did not field verify the Shapiro Report findings and only provided a review of the third party work. Terracon’s review of the topographic map and visual observations of the property did not identify streams or lakes.Several areas of surface water were observed on the central portion of the property which appeared to be the result of seasonal rain events or surface water runoff.No readily apparent low-lying areas and/or wetlands are known to be or have been reported to be present on the property. In summary,the Terracon report indicates that there are no wetlands,streams,or lakes on or immediately adjacent to the property based on a review of third party work and online resources. According to the Flood Plain Hazard Data Map,the 100-year flood plain encroaches roughly 4,400 square feet onto the northwest portion of the site (northwest of Building C)and 44,000 square feet within the stormwater detention pond (Exhibit 8).The applicant is proposing to fill 2,500 cubic feet of fill within the northwest portion of the site and remove approximately 250,000 cubic feet of the 100-year flood plain from the stormwater pond.As such,compensatory volume is being provided in the footprint of the combination wetpond in Tract B,at the elevations above the overflow detention line. Mitigation Measures:No further mitigation required. Nexus:Not Applicable b.Ground Water Impacts:Groundwater was observed at a depth of live to thirteen feet below current site grades in the test pit excavations.Con penetration test (CPT)data indicates groundwater within five to eight feet of the current surface.The groundwater seepage observed by the geotechnical engineer was likely representative of the groundwater table associated with the site. Dissipation testing indicated the static groundwater table was at a depth of between five and eight feet. Based on the current topographic survey,this equates to approximately elevation 16.This is consistent with groundwater seepage identified throughout the site.The static groundwater level indicated likely represents the near seasonal high level that could be expected at the site.Based on the soil and groundwater conditions ofthe site,the property would be mapped as a High Seismic Hazard (SH). Once stripping operations are complete,cut and fill operations would be initiated.The preliminary grading indicates the site would be filled by one to two feet to achieve building and access grades.Prior to placing fill,all exposed bearing surfaces should be observed by the geotechnical engineer to verify soil conditions are suitable for support of new fill or building elements.If excessively yielding areas are observed,and they cannot be stabilized in place by compaction,the affected soils should be excavated and removed to firm bearing and grade restored with new structural fill.If the depth of excavation to remove unstable soils is excessive,the use of geotextile fabrics,such as Mirafi 500X,or an equivalent fabric,could be used in conjunction with clean granular structural fill. ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report LONGACRES BUSINESS CENTER PHASE II LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 7 of 10 The geotechnical report states that if wet soils are encountered they will need to be dried by aeration during dry weather conditions.Otherwise the contractor should import a granular soil that can be used as structural fill.The moisture content of the soil at the time of compaction should be within 2%of its optimum,as determined by the American Society for Testing and Materials (ASTM)Test Designation D-698. Mitigation Measures:No further mitigation required. Nexus:Not Applicable C.Stormwater Impacts:The applicant submitted a Preliminary Drainage Report by Coughlin Porter Lundeen (dated August 21,2015;Exhibit 13).The stormwater design for the project was based on the Development Agreement and supplemental amendments to that document between the City of Renton and The Boeing Company.This agreement has adopted the 1990 King County Surface Water Design Manual (KCSWDM).Based on the City’s flow control map,this site falls within the Peak Rate Flow Control Standard,Existing Conditions.The proposed drainage system would include a new network of underground pipes,catch basins,curbs and gutter,to collect surface water runoff throughout the site and direct it to a detention/wet pond for water quality treatment and flow control.Runoff from the building roofs would be collected into roof drains and routed directly to the proposed detention/wet pond via pipe flow.Runoff from the new pond would be discharged to the north,into the previously developed Longacres Office Park drainage system within the Boeing property.From there the drainage flows into Springbrook Creek and ultimately the Duwamish River. The proposed system would be developed to mitigate peak runoff rates through a single detention/wet pond.The calculated detention facility includes volume capacity for the 2-year and 10-year storm events,in accordance with the 2009 KC-SWDM Section 1.2.3. The stormwater conveyance has been designed such that the 100-year flow is conveyed without overtopping the crown of the roadway (or drive aisle)or flooding any building.The preliminary design shows the following:1)a combination of 12-inch to 24-inch storm drain pipes and sheet flow;2)a 24-inch storm drain pipe would discharge into the detention wetpond (Exhibit 14);and 3)connection from the pond to the existing Longacres 48”storm system to the north.Final conveyance capacity conditions of proposed system would be analyzed and final pipe sizing will be performed with the final drainage system design in accordance with Chapter 4 of the City of Renton Amendments to the KCSWDM. A Construction Stormwater Permit (NPDES)from the Department of Ecology is required for sites over an acre. Mitigation Measures:No further mitigation required. Nexus:Not Applicable 3.Vegetation Impacts:The property was previously cleared for the former sports racing track land use.The site has been vacant for a number of years and the condition is now open field covered with moderate growth of brush, weeds,grass and sporadic trees.The existing trees onsite were either planted with the previous development,or are volunteers that have since grown on the site.The majority of the existing trees are Cottonwood and Lombardy Poplars.Both species have been identified by the landscape architect as short lived,weak wooded tree species that are considered to be unsuitable for the built environment due to the very invasive root systems (Exhibit 17).These species can often result in unnecessary damage to paved surfaces and underground utilities and/or may become hazardous concerns during a heavy storm event. Other onsite tree species include Acacia,Cedar,Spruce,and Alder along with other deciduous trees located immediately off-site. There are 53 significant trees that intermittently appear on parcels 088670-0150,-0190,while parcels -0090 and -0100 have very few existing trees.The applicant is proposing to retain seven (7)priority three trees ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report LONGACRES BUSINESS CENTER PHASE II LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 8 of 10 (RMC 4-4-130H.1.b)as part ofthe site plan review process.Significant tree preservation is proposed within the project perimeters of the site.The retained trees are as follows:two 28”cottonwood trees along the western property line,one 27”alder near the southwest property line,three poplar trees along the west property line (2’clump,15”and 23”),and one 39”poplar near the southwest corner of the detention wetpond.In order to comply with the tree retention requirements to retaining a minimum of 10 percent (10%)of existing significant trees in commercial zones,the applicant would be required to retain up to 5.3 significant trees onsite.The applicant meets the tree retention requirements by retaining a total of 7 existing significant trees throughout the site (Exhibit 5).The balance of the trees would be removed due to unsuitable species or due to site grading constraints (for example:2 feet of fill is proposed in most areas). The applicant is proposing to replant the site with 178 canopy trees (American sweet gum,red oak,gold falls zelcova),68 columnar trees (bowhall red maple,columnar tulip tree),167 small deciduous trees (vine maple, paperbark maple,flowering dogwood,quaking aspen),15 weeping Alaska cedar,51 shore pine,110 Douglas fir,and 55 excelsa cedar trees.All new landscaping would be covered with 2”depth of mulch and would receive a fully automatic irrigation system.The detention wetpond tract (Tract B)would receive a temporary irrigation system.The applicant is also proposing to plant native shrubs,accent shrubs,groundcover plants, perennial/ornamental grasses,sod lawn,native hydroseed with wildflower mix,and hydroseed throughout the site.Around the perimeter of the site,the landscaping plan includes a 4”depth 3/8”minus crushed rock over filter fabric walking trail.As proposed,the landscaping plan’s plant schedule does not distinguish tree count between the listed canopy trees,columnar trees,or small deciduous trees.In addition,the landscaping plan should be designed to include the other onsite amenities,such as signage and lighting.A final detailed landscape plan must be submitted and approved prior to issuance of the street and utility construction permits;this will become a recommended condition of approval during Hearing Examiner site plan review. The preliminary landscaping calculations include the following elements throughout the site plan:1) Frontage buffer along SW 27th St:40,019 SF;2)Green River Valley Wildlife Habitat Corridor:27,203 SF;3) Utility easement open space:47,493 SF;4)Perimeter landscaping:71,538 SF (includes a 10-foot buffer on the west,east and southwest property lines,a 20-foot buffer on the north property line,and a 15-foot buffer on the southeast property line);5)Parking lot landscaping:34,821 SF;and 6)Additional site landscape area:40,019 SF.Additional landscaping analysis will be included in the Hearing Examiner Staff Report. Mitigation Measures:No further mitigation required. Nexus:Not applicable 4.Noise Impacts:Existing noise within the vicinity of the subject site is primarily composed of trains and vehicles from SW 27th St to either the Tukwila Sound Transit Station at 7301 Longacres Way in Tukwila,the Federal Reserve Bank at 2700 Naches Ave SW,or the Bank of America Operations Center at 2985 Naches Ave SW. Temporary construction noise is anticipated as a result of the subject project.Based on the provided construction mitigation description,the applicant has indicated that construction is anticipated to begin in December 2015 with a completion date of June 2017.At this time,the applicant has indicated that construction work would occur from 6:00 a.m.to 10:00 p.m.on Monday through Friday and from 6:00 a.m. to 6:00 p.m.on Saturday (Exhibit 18)which is outside the City of Renton permitted construction hours of 7:00 a.m.to 8:00 p.m.on Monday through Friday,and Saturday by permission only.Final construction hours will be determined by the City at the preconstruction meeting.The site is surrounded by commercial development.No excessive levels of noise are expected to be generated during the operation of the completed project. Mitigation Measures:No further mitigation required. Nexus:Not Applicable ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report LONGACRES BUSINESS CENTER PHASE II LUA5-000630,ECF,MOD,SA-H Report of September 21,2015 Page 9 of 10 5.Transportation Impacts:The subject site fronts onto SW 27th St and Oakesdale Ave SW.The applicant submitted a Traffic Impact Analysis completed by TENW (dated August 21,2015;Exhibit 15).The memorandum included information that the proposed project is estimated to generate a total of 3,178 new weekday daily trips with 485 new trips occurring during the weekday AM peak hour (427 entering,58 exiting),and 437 new trips occurring during the weekday PM peak hour (74 entering,363 exiting).Based on the results of a traffic operations analysis at the offsite study intersections (Naches Ave SW I SW 27th St and Oakesdale Ave SW I SW 27th St),the study intersections currently operate at LOS A and B,and are expected to continue to operate at LOS B in 2017 with the proposed project.More specifically,the Naches Ave SW I SW 27th St intersection is expected to operate at LOS A in 2017 without the project and LOS B with the proposed project.The Oakesdale Ave SW I SW 27th St intersection is expected to operate at LOS B in 2017 without or with the proposed project and no significant adverse transportation impacts are anticipated with the proposed Longacres Business Center Phase II development. The proposed site access on SW 27th Street would form a new north leg (private access road)to the existing all-way stop controlled intersection at Naches Ave SW I SW 27th Street.The applicant is proposing to retain the existing all-way stop intersection under its current status with only minor revisions associated with creating the new north leg of the intersection for site access.It is anticipated that the intersection would be modified to its ultimate configuration in the future when SW 27th is extended to the west to connect with Strander Blvd.Alternatively,the westbound lanes of SW 27th St may be opened up by relocating the existing restrictive c-curbing in order to allow a dedicated right-turn lane into the site at Naches Ave SW. The applicant is proposing a full access driveway on Oakesdale Ave SW in order to allow all turn movements and be configured with separate outbound left and right turn lanes.A center two-way left turn lane exists on Oakesdale Ave SW which would provide a left turn lane for traffic entering the site and a center refuge lane for traffic exiting the site.It is estimated that this location would expect to operate at LOS C or better in 2017 with the proposed project.The results of the traffic analysis show that no major improvements,such as signalization,are needed at either site access locations. The right-of-way (ROW)width on SW 27th St is 90 feet,SW 27th Street requires 91 feet of ROW or 0.5 feet of dedication.A sidewalk was recently constructed on the north side of SW 27th St and it currently serves both pedestrians and bicyclists until a separated multi-use trail is constructed on the north side of SW 27th St.Construction of the multi-use trail would be in coordination with the City of Renton Transportation Division for location,layout,connection to light rail station,and in accordance with the adopted Trails Plan. Street frontage improvements on SW 27th Street would include an ADA accessible sidewalk ramp at the northwest corner of the Naches Ave SW I SW 27th St intersection. The road standards for Oakesdale Ave SW include a 103-foot ROW that includes the following improvements:8 feet of sidewalks,8 feet planter strip,curb and gutter and 8 foot parking lanes with 5 foot bike lanes and street lighting.These standards would trigger 6 Y2 feet of ROW dedication on Oakesdale Ave SW.The applicant has submitted a street modification in order to provide an uninterrupted on-site pedestrian trail and continuous native landscaping.One of the written justifications listed by the applicant for this exemption from the identified standards is to allow for improved landscape screening of the project. For a modification to be granted,the project must also comply with the decision and design criteria stipulated in RMC 4-9-250D.2. It is anticipated that the proposed project would not significantly or adversely impacts the City of Renton’s street system,subject to the payment of code-required impact fees and the construction of code-required (or approved modifications of)frontage improvements (Exhibit 21).The fee,as determined by the Renton Municipal Code at the time of building permit issuance,shall be payable to the City. A concurrency recommendation will be provided in the staff report to the Hearing Examiner based upon the test of the citywide Transportation Plan,consideration of growth levels included in the LOS-tested ERC Report LUA15-000630 City ofRenton Department ofCommunity &Economic Development Environmental Review Committee Report WNGACRES BUSINESS CENTER PHASE II LUA15-000630,ECF,MOD,SA-H Report of September 21,2015 Page 10 of 10 Transportation Plan,payment of a Transportation Mitigation Fee,and an application of site specific mitigation.The development will have to meet the City of Renton concurrency requirements. Mitigation Measures:No further mitigation required. Nexus:Not applicable 6.Fire &Police Impacts:Police and Fire Prevention staff indicated that sufficient resources exist to furnish services to the proposed development with 150 calls for service estimated annually by the Renton Police Department.The development is subject to the construction of code-required improvements and the payment of code- required impact fees (Exhibit 21). Mitigation Measures:No further mitigation required. Nexus:Not applicable 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 ofthis report and/or listed under Exhibit2l “Advisory Notes to Applicant.” V Copies of all Review Comments are contained in the Official File and may be attached to this report.

The test borings were advanced using mud rotary drilling methods.Soil samples were obtained at fiveJoot intervals in general accordance with American Society for Testing and Materials (ASTM)Test Designation 1)- 1586.Using this procedure,a 2-inch (outside diameter)split barrel sampler is driven into the ground 18 inches using a i40..pound hammer free falling a height of 30 inches.The number of blows required to drive the sampler 12 inches after an initial 6-inch set is referred to as the Standard Penetration Resistance value or N value,This is an index related to the consistency of cohesive soils and relative densiw of cohesionless materials.N values obtained for each sampling interval are recorded on the boring logs.All soil samples were visually classified in accordance with the Unified Soil Classification System (USCS)described on the attached Figure 2.The boring logs are presented as Figures 3 through 8.Laboratory testing completed on soil samples obtained included determination of the soils in place moisture content.Results of the laboratoiy moisture contents for the soil samples are shown on the boring logs opposite the samples on which they were performed.

TENW SUBJECT:Longacres Business Center Phase 2 Traffic Impact Analysis TENW Project No.5093 This memorandum documents the traffic impact analysis completed for the proposed tongacres Business Center Phase 2 project.The project is located west of Oakesdale Ave SW on the north side of SW 27th Street across from the proposed Longacres Business Center (Phase 1)prolect in Renton,WA (see Figure 1). Executive Summary Project Description.The proposed project would include up to 320,000 square feet of office space on a currently vacant site.Vehicular access to the site would be provided at 2 separate access driveways,one on SW 27th and one on Oakesdale Ave SW.The site access driveway on SW 2lth St will form the north leg of the existing Naches Ave SW/SW 2lth St all-way stop controlled intersection and will provide full access to all turning movements.The new driveway on Oakesdale Ave SW will provide full access to all turning movements.For the analysis in this report,a 201 7 horizon year was used.This project is located within Phase IVof the Boeing tongacres 01/ice Park and is subject to the 2003 Development Agreement and Strander Agreement. Trip Generation.The proposed project is estimated to generate a total of 3,178 new weekday daily trips with 485 new trips occurring during the weekday M’\peak hour (427 entering,58 exiting),and 437 new trips occurring during the weekday PM peak hour (74 entering,363 exiting). Traffic Operations at Study Intersections.Based on the results of a traffic operations analysis at the off- site study intersections,the study intersections currently operate at LOS A and B,and are expected to continue to operate at LOS B in 20 17 with the proposed project. Access Analysis.With the proposed site access via the north leg at Naches Ave SW/SW 27th Street, the intersection is proposed to remain as an all-way stop with only minor revisions associated with creating the new north leg of the intersection for site access.It is assumed that the intersection will be modified to its ultimate configuration in the future when SW 2/th is extended to the west to connect with Strander Blvd.The results of the site access LOS analysis show that the movements at both access locations are expected to operate at LOS C or better in 20 17 with the proposed project.These results show that no major improvements such as signalization are needed at the site access locations. Mitigation.No significant adverse transportation impacts are anticipated with the proposed Longacres Business Center Phase 2 development.Transportation impact fees are anticipated to be requited and will be determined prior to building permit issuance based on discussions with the City of Renton and Boeing. iransr EXHIBIT 15 11400 SE 425)889-6747 August 14,2015 1ffCZ fl Mr.Jon Blaha Entire Document 5OSouthTenthStreet,Suite 300 Available Upon Request Minneapolis,MN 55403-2012 RE:Confirmation of Environmental Setting Approximate 25.88-Acre Area Lots 9-10,15-19,and Tract C,Boeing Longacres Park Renton,King County,Washington Dear Mr.Blaha: Terracon Consultants,Inc.(Terracon)has been retained by Ryan Companies US,Inc.(Ryan)to provide confirmation of the general environmental setting for the approximate 25.88-acre vacant parcel legally described as Lots 9-10,15-19,and Tract C of Boeing Longacres Park,City of Renton (City),King County,Washington (the Property).The Property includes the entirety ofKing County Tax Assessor Parcel Numbers 0886700090,0886700100,0886700150,0886700160, 0886700180,0886700190,0886700380,and 0886700170.The Property is located in part of the south V2 Of Section 24,Township 23 N,Range 4 E and is north of SW 27th Street and west of Oakesthle Avenue SW. Per your request,Terracon has prepared this letter to summarize our findings regarding the potential for wetlands,streams,lakes,and critical habitat to be present at the Property. Information reviewed by Terracon for these findings was limited to available on-line resources and/or from prior reports provided to Terracon from Ryan. Wetlands Terracon reviewed the National Wetlands Inventory (NWI)map,published by the U.S. Department ofthe Interior Fish and Wildlife Service (see attached).The NWI map did not identify a wetland area on the Property.Freshwater Forested/Shrub wetlands and Freshwater Emergent wetlands were identified on the east-,west-and south-adjoining properties respectively, approximately 80 to 300 feet from the Property boundary.A report entitled “Longacres Office Park,Surface Water Management Project,Conceptual Wetland Mitigation Plan”prepared for Boeing Commercial Airplane Group (Boeing)by Shapiro and Associates,Inc.(Shapiro);dated August 1998 (Shapiro Report)was prepared for a 164-acre parcel which included the Property. No wetland areas were identified on the Property.In addition,a flood insurance rate map (FIRM)for the Property (see attached)identifies a 100-year floodplain,Zone AE,in close proximity to the northwestern Property boundary,which may extend onto the Property.The base flood elevation shown on the FIRM for Zone AE is 16 feet above mean sea level.Southern portions ofthe site are located within Zone X,outside the 100-year or 500-year flood zones.

EXHIBIT 20 Contact:Hotly Trader I425-430-751 9 j htrE’Police Plan Review Comments Recommendations:I 50 Police Calls for Service Estimated Annually To protect materials and equipment it is recommended that all materials and tools be locked up when not in use.The site will need security lighting and any construction trailer should be completely fenced in with portable chain link fencing.The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate thatthis area is private property.Construction trailers should be kept locked when not in use,and should also have a heavy duty deadbolt installed with no less then a I 1/2”throw when bolted. Glass windows in the trailer should be shatter resistant. I also recommend the business post the appropriate “No Trespassing”signs on the property while it’s under construction.This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials.Due to the isolated location of this site,the use of private security personnel to patrol the site during the hours of darkness is recommended. All exterior doors should be made of solid metal or metal over wood,with heavy duty deadbolt locks,latch guards or pry resistant cylinders around the locks,and peepholes.If glass doors are used,they should be fitted with the hardware described above and additionally be fitted with a layer of security film.Security film can increase the strength of the glass by up to 300%,greatly reducing the likelihood of breaking glass to gain entry.Access to the back of the buildings should be limited,preferably with security fencing,as these areas could be vulnerable to crime due to the lack of natural surveillance by business customers or employees. It is recommended that the commercial areas be monitored with recorded security alarm systems installed.It’s not uncommon for businesses to experience theft and/or vandalism during the hours of darkness.An auxiliary security service could be used to patrol the property during those times.It is important to direct all foot traffic towards the main entrance of the buildings.Any alternative employee entrances should have controlled access doors to prevent trespassing. All areas of this project need to have adequate lighting.This will assist in the deterrent of theft from motor vehicle (one of the most common crimes in Renton)as well as provide safe pedestrian travel for both employees and customers. Both structures should have building numbers clearly posted with numbers at least 12”in height and of a color contrasting with the building.This will assist emergency personnel in locating the correct location for response.
