Project Description Boeing plans to improve N.6"Street between Logan Avenue N.and the Cedar River,as needed for the Boeing Logistics Project.Improvements along N.6th Street and within the Shoreline jurisdiction include installing a sidewalk,extending the storm drainage system and adding a catch basin,installing two new street lights,removing an existing telecom utility pole,adding curb and gutter improvements,repainting on the road,and adding a vegetated planting strip between the new sidewalk and N.6th Street (in an existing impervious area)(See Figure 2). New street lights will be added along the south side of N.6h Street spaced approximately 70 feet apart,starting at the southeast corner of N.6t"Street and N.Riverside Drive.The street light poles will be in the 3-foot wide landscape strip,the ]uminaire will be about 35 feet above the ground,and each LED fixture will provide about 9,000 to 10,000 lumens. Also proposed is a five-foot wide,paved path connecting the N.6th Street sidewalk with the Cedar River Trail (See Figure 3).There is currently no crosswalk here,leaving pedestrians to cross Nishawaki Lane (Riverside Drive)in a high traffic area with challenging sight lines.The proposed trail connector will require the removal of some of the ornamental shrubs and the installation of an asphalt pathway in an area currently composed of maintained shrubs and mulch. 750 Sixth Street South Kirkland,WA 98033 /,425.822.5242 j'425.827.8136 watershedco.com Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac August 25,2014 Page 2 Concurrent with Boeing's plans,PSE is proposing to convert a single-phase,12.5 kV overhead powerline on N.6th Street into a three-phase line that will provide greater capacity and reliability for the Boeing manufacturing operations at Renton Municipal Airport (See Figure 1). The new lines will be larger in diameter (from 0.25 inches to 0.934 inches)due to a larger conductor and plastic insulation,which reduces the risk of bird electrocution.Project components within the shoreline environment include expanding the number of overhead lines from two to four,replacing two existing wood utility poles with like-kind poles but six inches larger in diameter,replacing the existing utility pole cross-beams to support the new lines,and installing a new underground vault and above ground meter cabinet for the expanded powerlines that will be placed underground on the west side of the Cedar River.Ground disturbance will be limited to the construction of the underground vault,which will measure 7 feet wide x 7 feet wide x 3.5 feet deep and may include an additional one foot of excavation to allow for gravel bedding and an additional one foot of excavation and backfill on all sides for a total impervious addition of approximately 64 square feet.The meter cabinet,which will be mounted on top of the vault,will measure 56"wide x 72"wide x 48"tall for a total volume of 4.3.cubic yards.The cabinet will provide weather protection for the meter itself and hardware for securing terminations for the underground cables.All other ground work will be conducted in areas that are entirely impervious,including the N.6th Street right-of-way and adjacent sidewalks.No removal of any trees or shrubs will occur as part of the proposed powerline replacement project. Total new impervious surfaces are anticipated to be 387 square feet,including PSE's utility vault west of the river and the trail connector/pedestrian walkway east of the river.To offset these unavoidable impacts,455 square feet of sparsely-planted,ornamental landscaping adjacent to the east side of Riverside Drive (approximately 140 feet north of the trail connector) will be enhanced with a dense,native shrub community.Additional areas of impervious surface within the shoreline environment (approximately 300 square feet)along N.6h Street will be removed and replaced with a three-foot-wide planting strip. To minimize potential avian hazards,non-conductive tree wire and non-spinning bird flappers will be placed on the new powerlines.The bird flappers reduce the chance of birds colliding with the lines,while the tree wire provides insulation from electrical conductivity,reducing the risk of bird electrocution. Existing Conditions The project area extends along the south side of N.6'"Street from Logan Avenue N.to the terminus of N.6'"Street,over the Cedar River to an existing utility pole just west of the East Perimeter Road on the airport property (See Figure 1).Only the western approximately 400 •linear feet of the project area is located in the shoreline environment.Vegetated areas are limited to relatively narrow areas adjacent to the river.West of the Cedar River,vegetation includes mowed grass separated from the armored riverbank by the East Perimeter Road.The thorelineFawirmnent]:unctitmal Effects Analysis Puget Sound linergy ',Andy Padvorac August 25,2014 Page 3 western riverbank is dominated by invasive 5cot's broom and lield grasses,lhe eastern, armored riverbank is dominated by a mix t invasive Itimalavan blackberr;,,Japanese knotweed,and reed t anarwrass and abuts a concrete wall approximately Iour leer tall.

Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padwrac August 25,2t)14 Page 4 Figure 2:Approximate Road Improvement and Trail Connector Project Area *Figure depicts project area within Shoreline Environment only The functions and values of the shoreline environment are extremely limited due to the existing conditions and the extent of the surrounding development.The project area lacks native vegetation,structural diversity,and special habitat features that would provide substantial habitat lor resident and migratory animals.The ornamental shrubs present east of the river provide some cover opportunities for songbirds,but as non-native,non-fruit-bearing shrubs, they provide little forage opportunities.The high traffic setting creates noise and substantial habitat fragmentation,eliminating the use of all areas,except the Cedar Rivet"itself,as a significant migration corridor.The ornamental shrubs east of the river also provide minor reductions in stormwater flows entering the river,although due to a lack of herbaceous vegetation,the area does not possess significant potential to improve water quality by trapping and removing sediments and pollutants.West of the riwr,on the airport property, functionality is extremely licnited,as the vegetation is mostly mowed lawn grasses that provide essentially no wildlife habitat value.Habitat function is further reduced as airport operations typicalh'require removal of wildlife as an aviation safety precaution.The ability of mowed lawn to provide some level of groundwater recharge,surface flow reduction,and water quality treatment cannot be summarily dismissed;however,mm,ved grass does not have the vertical structure necessary to trap and filter sediments or to significantly slow surface water velocities. Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvnrac :\ugust 25,2014 Page 5 Thureid.m.',the nveralJ ILlnt tiol'*1 the terrestrial shoreline environment west of the river can be effectively described as minimal. Areas Irom Riverside Drive eastward along N.6 Street are almost exclusively composed of asphalt and are subject to high traffic \:lumes.These areas provide no ecological fundions related to the Cedar River Shoreline F,nvironment. Figure 3:Approximate Trail Connector Alignment Functional Impact Analysis Replacing pervious areas with impervious (lawn,mulch,and sparse shrubs with asphalt and steel)always represents a functional loss.However,the areas impacted by the current proposals only provide minimal lunction,mostly related to groundwater recharge and a minor redtlction ill stormwater velocities.As described abow',mowed lawn (and empty mulch)does not have the vertical structure necessary to trap pollutants and sediments or to signiticantb/ Iedtlte sl,nrmwater veJocilJe.]lluretore,ctmverting Stlch areas {o ,sphall,while representing a loss in lunction,does mt represent a substantial loss.The planter strip being installed adiacent Io the N.(:a Street sidewalk will represent an approximately 300 squareqoot replacement *t impervious asphalt with native shrubs.While the functional value is somewhat limited title to Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac August 25,2014 Page 6 the separation from the Cedar River by Riverside Drive,it does provide a minor functional lift for water infiltration within the Shoreline Environment as compared to the existing condition. The habitat function provided by the impact areas is also minimal,with mowed lawn providing very low levels of function.The ornamental shrubs provide some cover for songbirds,but the relative lack of density and the lack of fruit-and nut-producing,native species severely limits the forage opportunities for wildlife.None of the shrubs proposed for removal do,or ever will, provide shade,detritus material,or large woody debris recruitment for the Cedar River.The proposed new planting areas within the shoreline habitat total approximately 755 square feet, including approximately 455 square feet in the 100-foot stream buffer for the Cedar River.By mitigating the impact area at a ratio of approximately 2:1 (including 1.2:1 in the buffer),while improving the density,diversity,and species composition of the shrub species present,the post- project area will represent a significant increase in wildlife cover and forage opportunities beyond the existing conditions.These functions are particularly valuable in dense,urban settings,as refuge areas are not typically available and are highly valued by wildlife. The visual and aesthetic impacts of two new electrical conductors is insignificant,as they will be in a similar location as the existing lines and will be on a parallel,horizontal plane.The non- spinning bird flappers and tree wire will further reduce the risk of birds colliding with or being electrocuted by the transmission lines.Similarly,the addition of two new street lights will not represent a significant impact,as the area is already heavily developed and the existing terrestrial habitat is severely limited. The replacement of the impervious areas adjacent to the N.6"Street sidewalk with native vegetation and pervious soil will help minimize the impacts associated with the new impervious surface from the utility vault and the trail connector.This,combined with the substantial increase in relative wildlife habitat functions associated with the installation of a dense native shrub community as a replacement for sparsely-planted ornamental shrubs, mulch,and mowed lawn,leads to the conclusion that the totality of the proposed plan represents no-net-loss of ecological functions in the Shoreline Environment.

Functional Effect analysis,prepared by The Watershed Company,dated April 29,2014 City Comments,Airport,Community Services,and Plan Review PSE profile of horizontal directional drilling FINDINGS OF FACT: .The applicant is requesting a Shoreline Substantial Development Permits to upgrade the 12.5 kV electrical distribution system serving the Renton Airport Aprons A and B from a two-wire to a four-wire system and street frontage improvements including a 6 foot sidewalk and 5 foot landscape strip along N 6th St. 2 The site currently is primarily asphalt and/or concrete impervious surfaces along N 6th St.and in the airport parcel.The portion of the extended sidewalk in the Cedar River Park is landscaped. 3.The PSE electrical distribution system is currently comprised of overhead lines that cross the cedar river. 4.The closest work to the OHWM would be approximately 30 feet along the east bank and 65 feet along the west bank of the Cedar River. 5.The proposed PSE upgrades would consist of the following: East bank of the Cedar River:Replacing one pole (P02)with a new pole of the same height and up to 6 inches in diameter larger.The wood cross-arms and hardware that currently are atop pole P02 would be replaced with new like-kind material which would support the proposed 3-phase electrical distribution system.Pole 3 (P03)is proposed to be removed and replacement about 50 feet to the east outside the Shoreline Jurisdiction.(Exhibit 6) West bank of the Cedar River:a new 7 foot x 7 foot by 3.5 foot vault would be installed just west of the existing pole (P01)in an existing grass field at the Airport property.The vault would be located underground (Exhibit 6). Over the Cedar River:The overhead electrical lines would remain overhead at the river crossing.To deter birds from striking the wires "Fixed Bird Flapper"devices would be attached to the conductors above the river. .The applicant has proposed street improvements along N 6th Street to include a 6 foot sidewalk and a 3 foot landscape strip.These improvements are proposed to be located on the east side of the Cedar River only and would extend along the south side of N 6th St.In addition;these improvements would include the extension of the storm drainage system and catch basins,two new street lights,and the removal of an existing telecom City ofRenton Department o.f Comh._.,ity&Economic Development Shoreline Management Permit N 6th St,Improvments by Boeing and PSE LUA14-O00581,SM DATE OF PERMIT:June 26,2014 Page4of 17 utility pole.However,comments were received from the City's Plan Review division (Exhibit 10),which states the streets should include a 6 foot sidewalk,5 foot planting strip,0.5 foot vertical curb and asks the applicant to consider the installation of a 5 foot bike lane. ,Due to the proposed new sidewalk along N 6th Street an ADA connection is required to the Cedar River Trail located on the City's park property just north of N 6th Street and along Nishiwaki Ln.,which provides access to the Cedar River Park.Comments were received from the Community Services Department (Exhibit 10)identifying that the proposed design and layout of this connection is not approvd as designed.As such, this design would need to be reviewed and approved by both the City's Transportation Department and Community Services;staff recommends this review as a condition of approval. 8.The applicant submitted a Functional Effects Analysis prepared by The Watershed Company,dated April 29,2014. ,The site is located in a flood hazard area and a flood way,a seismic hazard area,and an area that contains sensitive slopes (along the river bank),powerlines would extend over the Cedar River which is a shoreline of the State,no other critical areas exist on site. 10.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 have been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. 11.Roads and Local Service Utilities are permitted outright in Table 4-3-090E1 Shoreline Use Table. 12.The following table contains project elements intended to comply with the SMP bulk and dimensional standards and policies,as outlined in RMC 4-3-090: A:,,COMPREHENSlVEPN COMPLIANCE AND CONS STENCY,SHOREL NE ELEMENT ,, te.s te s ocated n the-Shore ne H gh-ntens ty Overlay D str ct..Tile objective of,the Higl; ....ntens ty:Overlay is.to..,provideo.pportumbes for.....large,sca e off ce,and commerc al emp oyment, centers,as :we!l,as.multl;famdy residential use and pubhc services..This;district prowdes. toppotunites for water-dependent and waterTonented usesLwhlleprotectLngexsting eFo!ogcal .funct ons and.,>,restormg .ecological fun cbons m areas that haye been'prev ously degraded. ,Deve opment may a so prov oe.roE pun c use.ane/orcommun ty use,espe¢a y.access,to:ana.

Permitted uses should be designed and conducted to minimize,in so far as practical,any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline ecological functions that should be protected include,but are not limited to,fish and wildlife habitat,food chain support,and water temperature maintenance•Shoreline processes that shall be protected include,but are not limited to,water flow;littoral drift;erosion and accretion;infiltration;ground water rechai'ge and discharge;sediment delivery,transport,and storage;large woody debris recruitment;organic matter input;nutrient and pathogen removal; and stream channel formation/maintenance. Staff Comment:The Applicant submitted a Functional Effects Analysis prepared by The Watershed Company,dated April 29,2014.The report states that replacing pervious areas with impervious areas always represents a functional loss,however in this case the loss is not considered to be a substantial loss.The applicant has proposed to add a planter strip which would represent approximate 300 square feet of replacement impervious asphalt with native shrubs.In addition,staff has requested this planter strip to be increased-from the proposed 3 feet to 5 eet which would result in an additional reduction in impervious surface area.In addition,the applicant has proposed to provide 727 SF of enhancement native plantings in the City's Cedar River Park.The report concludes that the replacement of the impervious areas adjacent to N 6th St.sidewalk with native vegetation and pervious soil would help to minimize the impacts associated with the new impervious surface -from the utility vault and the trial connection.The replacement of impervious surface in combination with the substantial increase in relative wildlife habitat functions that would be associated with the installation of a dense native shrub community (plantings located on the City's Cedar River Park site)leads to the conclusion that the totality of the proposed p/an represent no-net-loss of ecological -functions in the Shoreline Environment.However,comments were received -from the City's Community Services Department which has indicated that the proposed mitigation plantings would not be permitted on City property as proposed.As such, with the removal of the 727 SF of plantings on the City's property the proposed project may result in a net loss of ecological-functions and values.Therefore,staff recommends as a condition of approval that prior to construction permit issuance -for the N 5th St.improvements an updated Functional Effects Analysis with City o[Renton Department of Comh,-,dty &Economic Development Shoreline Management Permit N 6th St,Improvments by Boeing and PSE LUA14-O00581,SM DATE OF PERMIT:June 26,2014 Page 6 of 17 Compliant if conditions are met associated mitigation be prepared for review and approval by the Current Planning Project Manager identifying an alternative proposal to mitigate the project to result in no net loss of ecologicalfunctions and values.

StaH Comment:The applicant has indicated that there is no bridge at the existing utility crossing.The proposed upgraded PSE lines would be within an existing utility corridor.The applicant has indicated that both the east and west stream banks and the stream bed would not be disturbed as a result of the utility upgrade.The applicant evaluated the option of tunneling under the Cedar River for the utifity lines and has reached the .following conclusions: A geotechnical study could .find rock cobbles that would block the drill or soils that would collapse before a casing could be inserted into the boring. Typically one would set the drilling equipment back .from the center of the river 100 .feet .for every ]-inch of drill size.This is intended to allow .for a gradual arc o.f the drill shaft and casing (Exhibit 11).Based on the proposed casing sizes and the general setback rule it b anticipated the drilling equipment could be 700 to 900.feet.from the river centerline.Based on thb assumption,the drilling equipment would need .to be set up on the airport property close to or within the runway o.f the airport.

Project Description Boeing plans to improve North 6t"Street between Logan Avenue North and the Cedar River,as needed for the Boeing Logistics Project.Improvements along N.6th Street and within the Shoreline jurisdiction include installing a sidewalk,extending the storm drainage system and adding a catch basin,installing two new street lights,removing an existing telecom utility pole, adding curb and gutter improvements,repalnting channelizafion on the road,and adding a vegetated planting strip between the new sidewalk and N.6th Street (in an existing impervious area)(See Figure 2).New street lights will be added along the south side of North 6th Street spaced approximately 70'apart,starting the southeast corner of North 6th Street and North Riverside Drive.The street light poles will be in the 3-foot wide landscape strip,the luminaire will be about 35 feet above the ground,and each LED fixture will provide about 9,000 to 10,000 lumens. Also proposed is a five-foot wide,paved path connecting the N.6th Street sidewalk with the Cedar River Trail (See Figure 3).There is currently no crosswalk present here,leaving pedestrians to cross Nishawaki Lane (Riverside Drive)in a high traffic area with challenging sight lines.The proposed trail connector will require the removal of some of the ornamental 750 Sixth Street South I Klrkland.WA 98033 /,42S.822.S241 I ,f 425.827.8116 I watorlhedco.corn Ot m 'I-XuJ Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac April 29,2014 Page 2 shrubs and the installation of an asphalt pathway in an area currently composed of maintained shrubs and mulch. Concurrent with Boeing's plans,PSE is proposing to convert a single-phase,12.5 kV overhead powerline on North 6th Street into a three-phase line that will provide greater capacity and reliability for the Boeing manufacturing operations at Renton Municipal Airport (See Figure 1). The new lines will be larger in diameter (from 0.25 inches to 0.934 inches)due to a larger conductor and plastic insulation,which reduces the risk of bird electrocution.Project components within the shoreline environment include expanding the number of overhead lines from two to four,replacing two existing wood utility poles with like-kind poles but six inches larger in diameter,replacing the existing utility pole cross-beams to support the new lines,and installing a new underground vault and above ground meter cabinet for the expanded powerlines that will be placed underground on the west side of the Cedar River.Ground disturbance will be limited to the construction of the underground vault,which will measure 7' wide x 7'wide x 3.5'deep and may include and additional one foot of excavation to allow for gravel bedding and an additional one foot of excavation and backfill on all sides for a total impervious addition of approximately 64 square feet.The meter cabinet,which will be mounted on top of the vault,will measure 56"wide x 72"wide x 48"tall for a total volume of 4.1 cubic yards.The cabinet will provide weather protection for the meter itself and hardware for securing terminations for the underground cables.All other ground work will be conducted in areas that are entirely impervious,including the North 6th Street right-of-way and adjacent sidewalks.No removal of any trees or shrubs will occur as part of the proposed powerline replacement project. Total new impervious surfaces are anticipated to be 387 square feet,including PSE's utility vault west of the river and the trail connector/pedestrian walkway east of the river.To offset these unavoidable impacts,727 square feet of sparsely-planted,ornamental landscaping adjacent to the trail connector will be enhanced with a dense,native shrub community. Additional areas of impervious surface (approximately 300 square feet)along N.6th Street will be removed and replaced with a three-foot-wide planting strip. To minimize potential avian hazards,non-conductive tree wire and non-spinning bird flappers will be placed on the new power lines.The bird flappers reduce the chance of birds colliding with the lines,while the tree wire prov!des insulation from electrical conductivity,reducing the risk of bird electrocution. Existing Conditions The project area extends along the south side of North 6'h Street from Logan Avenue North to the terminus of North 6h Street,over the Cedar River to an existing utility pole just west Of the East Perimeter Road on the airport property (See Figure 1).Only the western approximately 400 linear feet of the project area is located in the shoreline environment.Vegetated areas are ,h ,i'lil ,,:I1,,II,iirll]il I Ihi,'.i,lhll IIh,I,,ii il',• ]'likq I ':,1111:1 I!li I),,'tlhl ',1,1 :l,ic l,lll .ii 'till !]l!iil,'cl :,ii'IIIli I'i:I",;<.,qij,l,'lil ,l:llc'll',lq ','i I Cl Ili (,,J,il I:1',,:!',,,q I,Ili,:i ii !Jl,I,ili,',',l !'i I'.,,c'p:ii,lh'<l li:1/1111':,iiil,il j,,'!l:i il,i,,!1'1 !'1]''i ii,hi IL,,,I h' ,]c11111,1l,,111]i :l,lliiili[c ]1,,,Iil',,I I',,,i,L I,l>;,l:i,iJiLIli,ll;,l:,,,]1,',ll I1 :ii/:l ,lii',ll,li!,i ;I,>il ill C,;l l,,,:,ili',:l il',<i I'!hilill,,,lllLIJ I-I,,I ,]il,,ll ,,, I I ,,,,,,1 ,1,1 ,,,il III,II ,,!,,I ,':iii,il ,i]Jill i ,ii :,i,",,,11 i;:l:i,,I i/LLc],h,cl :1 I ill Ii I<,,I III,,ii ,1:',,11 ill I1':':!"I,[i I li',c',,:',,'1 li ,i hli,,I I,,,1 ,G,l,,:l,,l il<'l,ii h,,c ",11,',ili:,:l i:i,I,,i,lul,,;I li ,ll Ii,lll,ii,i]liiiil,iI hicil,,ilhl,,ll,,:liiili:l',l,iI li' I:h,:ili,I ,ll>1:1<'I [I ,,c i11,[li,i:,i,t c lli:I{l',/liiil ,',!',<'LILI,,II i'.li ,,i 1 III Ih, ii'1,I,,I iii,,i c,i I ,I Ih',i I,I I '1 I c' I I!lLIl,!II '\I:pI 'ci;'{illi:ih'I 'l-'d':lll!ll@!11111111181;'.'P:!llll'.P]1:i I;h,:hl(7'E:t [OCl,ll;I,II ,t¸ ]litLU,:!

The habitat function provided by the impact areas is also minimal,with mowed lawn providing very low levels of function.The ornamental shrubs provide some cover for songbirds,but the relative lack of density and the lack of fruit-and nut-producing,native species severely limits the forage opportunities for wildlife.None of the shrubs proposed for removal do,or ever will, provide shade,detritus material,or large woody debris recruitment for the Cedar River.By mitigating the impact area at a ratio of approximately 1.9:1,while improving the density, diversity,and species composition of the shrub species present,the post-project area will represent a significant increase in wildlife cover and forage opportunities beyond the existing conditions.These functions are particularly valuable in dense,urban settings,as refuge areas are not typically available and are highly valued by wildlife. The visual and aesthetic impacts of two new electrical conductors is insignificant,as they will be in a similar location asthe existing lines and will be on a parallel,horizontal plane.The non- spinning bird flappers and tree wire will further reduce the risk of birds colliding with or being electrocuted by the transmission lines.Similarly,the addition of two new street lights will not represent a significant impact,as the area is already heavily developed and the existing terrestrial habitat is severely limited. The replacement of the impervious areas adjacent to the N.6'h Street sidewalk with native vegetation and pervious soil will help minimize the impacts associated with the new impervious surface from the utility vault and the trail connector.This,combined with the substantial increase in relative wildlife habitat functions associated with the installation of a dense native shrub community as a replacement for sparsely-planted ornamental shrubs, mulch,and mowed lawn,leads to the conclusion that the totality of the proposed plan represents no-net-loss of ecological functions in the Shoreline Environment.

Reviewed by Steven True,PE Project Manager Teclnical Information ReportBoeingNorth6thStrln,t Improvements Rentnn,Washington BergerABAM,A 13.0362.06April25,2014PageIof8 SECTION 1:PROJECT OVERVIEW Tile proposed project is located within the North 6th Street public right-of-way at The Boeing Commercial Airplane 737 Airplane Production Renton Plant located on the southern shore of Lake Washington,within the City of Renton,Washington.The project site is bordered by The Boeing Commercial Airplane 737 Airplane Production Renton Plant to the north and the south, Ihe Cedar River to the west,and Logan Avenue North to the easl.Surrounding land use is predominanlly commercial,industrial,and retail.The Cedar River Trail system and associated park are located just west of the project site.A site vicinity map and project site maps are provided in Appendix A. The Boeing North 6th Street Improvements Project encompasses the addition of curb and gutter,a landscape planter,and raised sidewalk along the southern edge of N 6th St.Utility improvements including overhead power and communication modification,hydrant relocation and stormwater collection and conveyance modifications will be required to accommodate the new road section. It is the intent of this Technical Information Report to address the site improvements proposed by the project and the applicable conditions and requirements. Existing Conditions The topography of the entire project site is relatively flat,with slopes generally ranging from less than 1 percent to less than 2 percent from east to west.The project site encompasses the southern half of N 6th St,a small portion of the Cedar River Trail Park,and a portion of the Boeing Renton Production Plant.Runoff from the project site is collected by closed (pipe) conveyance systems which outfall to the Cedar River or to Lake Washington.The existing pedestrian facilities within this portion of the right-of-way are limited to a paved shoulder area. Table 1.1 below summarizes proposed surface coverage for the project site. In tile existing condition,stormwater run-off from the southern portion of N 6th St and the tributary area just south of the right-of-way line is collected and conveyed by both public and private stormwater systems.The existing public system collects a 12,770 sf area of the project site from the N 6th St public right-of-way and the adjacent private property within the eastern portion of the site and outlets directly to the Cedar River.The existing private system collects a 14,538 sf area of the project site from the N 6lh St public right-of-way and the adjacent private property within the western portion of the site and outlets to Lake Washington via the Boeing privately owned and maintained Nishiwaki trunkline as described in the Technical Information Report prepared by BergerABAM for the Boeing Renton Site Logistics Project,dated March 3, 2014.

Proposed Conditions Surface cover,topography and hydrology at the project site will be essentially unchanged by the proposed improvements.Table 1.1 below summarizes proposed surface coverage for the project site.The improvements proposed by the project include upgrading the pedestrian facilities with the addition of a raised sidewalk and landscape buffer with a raised curb and gutter. Utility Improvements Utility improvements including overhead power and communication modification,street lighting,hydrant relocation,and stormwater collection and conveyance modifications will be required to accommodate the new road section. Other utilities that are present within the project area are sanitary sewer,water (both domestic and fire-protection),gas mains,and underground communication lines.Existing utilities and building service connections will be protected and preserved throughout construction. Stormwater Improvements In general,stormwater runoff patterns for the project site will mimic existing;however the pollution generating impervious surface cover of the site will be slightly reduced with the addition of a landscape buffer.Stormwater run-off will also be redirected to eliminate sheet flow across the new raised sidewalk while marinating existing tributary basin sizes. Technical Information ReportBoeingNorth6thStreetImprovementsRenton,Washington BergerABAM,A13.0362.06April25,2014Page3of8 In both the existing and proposed condition,stormwater run-off from the southern portion of N 6th St and the tributary area just south of the right-of-way line is collected and conveyed by both public and private stormwater systems. The existing public system currently collects a 12,770 sf area of the project site from the N 6th St public right-of-way and the adjacent private property within the eastern portion of the site and outlets directly to the Cedar River.In the proposed condition,tile public system will collect a 12,551 sf area of the project site from the N 6th St public right-of-way. The existing private system currently collects a 14,538 sf area of the project site from the N 6th St public right-of-way and the adjacent private property within the western portion of the site and outlets to Lake Washington via the Boeing privately owned and maintained Nishiwaki trunkline.In the proposed condition,a 14,757 sf area of the project site from the N 6th St public right-of-way and the adjacent private property will be collected. The existing public storm system within the project site is a closed conveyance system consisting of 24-inch pipe and Type 2 catch basins.The project improvements will add a new Type 2 catch basin,replace an existing Type 2 catch basin,and add two new concrete inlets to the existing conveyance system.A total of 13 linear feet of new,12-inch high-density polyethylene pipe will be installed to connect the concrete inlets to corresponding catch basins. The new private collection and conveyance system just south of the public right-of-way on the Boeing Commercial Airplane Group Renton Production Plant includes 360 linear feet of 12-inch high-density polyethylene pipe,and three Type I catch basins.Roof drainage from an existing building located adjacent to the right-of-way will be collected in a 6-inch conveyance pipe and connected to this system.The private system connects to an existing private structure at the southeast corner of N 6th Avenue and Nishiwaki Lane,which is a part of the privately owned and maintained Boeing conveyance system.

PSE plans to upgrade the 12.5 kV electrical distribution system serving Renton Airport Aprons A and B.The existing single-phase system will be converted to a three-phase system to provide increased capacity and reliability.The utility system will be upgraded from a two-wire to a four- wire system and will remain an overhead utility river crossing. SHORELINE AREA West of the Cedar River 100 foot zone o Boeing -none o PSE -The existing wood pole will be replaced with a new wood pole of the same height and up to 6"larger in diameter,Pole-1 on PSE's work sketch.The wood cross-arms and hardware atop the pole will be replaced with new like-kind material which will support the new 3-phase electrical distribution system.The replaced pole will be very similar to the existing one (see photo and diagram below).A 7'x 7'x 3.5'vault will be installed just south of the pole in an excavation that will be 8'x 8'x 4.5';gravel will be used to backfill around the vault,forming a one-foot-wide gravel shoulder around the vault.The area where the vault will be placed is field grass that the airport maintenance staff mows. The three-phase overhead wiring at the top of the pole will transition to cables,going down the pole in new conduits,and will terminate in the vault at a primary service meter.Under a prior permit process,Boeing permitted the installation of underground cables from the new meter at this vault south to Apron A and B.New,overhead 3-phase electrical lines will be installed to the east across the river to replace the existing single- phase system.The existing electrical lines are #4 ACSR conductors (0.25"diameter).The proposed electrical lines will be tree wire which is covered irl black plastic and 0.934"in diameter.To deter birds from striking the wires,"Fixed Bird Flapper"devices will be attached to the conductors above the river.The existing telecommunications line mounted below the electric lines is owned by CenturyLink and will remain.

April 30,2014 Page 2 of 2 )f Boeing Apron A &B PSE Distribution Line Rebuild Project PSE Responses to Shoreline Utility Regulations 29-April-2014 Project Overview Boeing has requested that PSE construct improved electrical service to Aprons A &B,for improved capacity and reliability to its facilities.The request is for a 600 amp service at 12,500 volts.This requires athree-phase extension of a "feeder"circuit from a substation.Following are PSE responses to the City of Renton Shoreline Management Plan regulations. City of Renton SMP Use Regulations RMC 4-3-090.E.11:Utility Sections "a"and "d" a.Criteria for All Utilities: i.Local utility services needed to serve water-dependent and other permitted uses in the shoreline are subject to standards for ecological protection and visual compatibility.PBE Respoqae: The proposed electrical distribution line rebuild is needed for other permitted Boeing uses. ii.Major utility systems shall be located outside of shoreline jurisdiction,to the extent feasible,except for elements that are water-dependent and crossings of water bodies and other elements of shore-lands by linear facilities. PSE eepopee: Not applicable;the proposed project is not a major utility system. iii.New public or private utilities shall be located inland from the land/water interface,preferably out of shoreline jurisdiction,unless: PSE Response: Not applicable because: •All proposed work will be inland from the land/water interface. •The proposed project is not a "new"utility system.There are existing electrical distribution and telecom lines crossing the river at the project location,see Street View Photo.Exhibit A.The existing poles on each side of the river will be replaced with like-kind poles,the only difference will be removing the single-phase wire and installing three-phase wire.The new wire will be plastic coated tree wire to reduce the chance of bird electrocution.Fixed "bird flappers"will be attached to the wires to reduce the chance of injury to birds resulting from collision with wires. Therefore,criteria (a)and (b)below do not apply,although the proposed project complies with both. (a)Perpendicular water crossings are unavoidable;or pSE Rear,onae: Electrical service to existing uses within the airport site and on the west side of the river is provided from Paccar Substation,which is located on the east side of the river.The electrical lines must cross the river.A diagonal crossing would expand the visual presence with taller poles and a longer span of wires.It is logical for the crossing to remain perpendicular. (b)Utilities are necessary for authorized shoreline uses consistent with the Shoreline Master Program. pSE Response: PSE's proposed rebuild of the existing distribution line crossing is consistent witl4,M ivE D 1%I,v I.=viv.Linear facilities consisting of pipelines,cables and other facilities on land running roughly parallel to the shoreline shall be located as far from the water's edge as feasible and preferably outsidfhreli814 jurisdiction.PBE Iesoonse:CRY OF RENTON PLANNING DIVLSION Page 1 of g Boeing Apron A &B PSE Distribution Line Rebuild Project PSE Responses to Shoreline Utility Regulations 29-April-2014 Not applicable,the existing distribution line is perpendicular to the shoreline,not parallel -as will be the rebuilt distribution line. v.Linear facilities consisting of pipelines,sewers,cables and other facilities on aquatic lands running roughly parallel to the shoreline that mayrequire periodic maintenance that would disrupt shoreline ecological functions shall be discouraged except where no other feasible alternative exists.When .permitted,provisions shall assure that the facilities do not result in a net loss of shoreline ecological functions or significant impacts to other shoreline resources and values. PSE Response: Not applicable,the existing distribution line is perpendicular to the shoraline,not parallel -as will be the rebuilt distribution line. vi.Utilities shall be located in existing rights-of-way and corridors,whenever reasonably feasible. PSE Response: The proposed project is located in an existing utility corridor. vii.Local service utilities serving new development shall be located underground,wherever reasonably feasible.PSE Response: This project is needed to serve existing facilities.Rebuilding the existing electrical distribution lines underground in the shoreline area is not feasible,see section viii.below. viii.Utility crossings of water bodies shall be attached to bridges or located in other existing facilities,if reasonably feasible.If new installations are required to cross water bodies or wetlands they should avoid disturbing banks and streambeds and shall be designed to avoid the need for shoreline stabilization. Crossings shall be tunneled or bored where reasonably feasible.Installations shall be deep enough to avoid failures or need for protection due to exposure due to streambed mobilization,aggregation or lateral migration.Underwater utilities shall be placed in a sleeve if reasonably feasible to avoid the need for excavation in the event of the need for maintenance or replacement. PSE Response: There is not a bridge at the existing utility crossing.The proposed project will not disturb the river banks or bed and does net require any shoreline stabilization.PSE understands that the bridge that is located about 700 feet south has a movable bridge deck and would probably not be suitable for attaching conduits with electrical cables.The bridge located 2,500 feet south,along Logan Avenue, would require construction of a new electrical distribution line at an additional cost of over $400,000. Drilling under the river is not reasonably feasible. •It might not be technically feasible;the geotechnical study could find rock cobbles that would block the drill or soils that would collapse before a casing could be inserted. •The drilling might fail after starting due to conditions not reported in the geotechnical study •The rule of thumb is to set the drill equipment back from the center of the river 100 feet for every 1-inch of drill size.This is to allow for a gradual arc of the drill shaft and casing,Exhibit B and C.For two 6"conduits,a casing of 14"to 18"would be needed.Based on the rule of thumb,the drill equipment could be 700'to 900'from the river centerline.The drilling equipment would have to set up on airport property.Depending on the geotechnical study and final engineering,the equipment could be close to or within the runway,see Exhibit D. ix.In areas where utility installations would be anticipated to significantly alter natural groundwater flows, a barrier or conduit to impede changes to natural flow characteristics shall be provided. PSE Response: This project will not significantly alter natural groundwater flows,it will remain an overhead system. Page 2 of 9 J Boeing Apron A &B PSE Distribution Line Rebuild Project PSE Responses to Shoreline Utility Regulations 29-April-2014 x.Excavated materials from construction of utilities shall be disposed of outside of the vegetationconservationbufferexceptifutilizedforecologicalrestorationandshallbespecifiedinsubmittal materials.PSE Response: Excavated materials from this project shall be disposed of outside of the shoreline area. xi.Utilities shall be located and designed to avoid natural,historic,archaeological or cultural resources to the maximum extent feasible and mitigate adverse impacts where unavoidable. PSE Response: Rebuilding the existing overhead utility crossing will minimize impacts to natural,historic, archaeological or cultural resources to the maximum extent feasible,and no mitigation measures are planned, Related to natural features,bald eagles are known to prey on fish in the river in this area and land on objects in the area.For that reason,PSE plans to apply its avian protection standard to the proposed project,which will reduce the likelihood of bird injury and mortality from current conditions. xii.Utilities shall be located,designed,constructed,and operated to result in no nat loss of shoreline ecological functions with appropriate on-and off-site mitigation including compensatory mitigation.PSE Reapolaa: This project will not result in a net loss of shoreline ecological functions.See the Functional Effects Analysis report from The Watershed Company dated April 29,2014. xiii.All utility development shall be consistent with and coordinated with all local government and State planning,including comprehensive plans and single purpose plans to meet the needs of future populations in areas planned to accommodate growth. PSE Resnonae: Future energy demands are being taken into consideration in the planning of this project. xiv.Site planning and rights-of-way for utility development should provide for compatible multiple uses such as shore access,trails,and recreation or other appropriate use whenever possible.Utility right-of- way acquisition should be coordinated with transportation and recreation planning.pSl Resoonae: The existing overhead distribution line crossing of the river is compatible with existing recreation uses along the river corridor,including the trail and the park along the east side of the river.The proposal will maintain the same compatibility. xv.Vegetation Conservation: (a)Native vegetation shall be maintained whenever reasonably feasible. PSE Reaoonse: Not applicable,no native vegetation will be removed or disturbed by this project.On the west side of the river,64 square feet of field grass will be removed by placement of a new vault.The loss of grass will be compensated for by landscaping on the east side of the river,sea the Landscape Plan. (b)When utility projects are completed in the water or shore-land,the disturbed area shall be restored as nearly as possible to the original condition.PSE Rasnonaa: Not applicable,no utility work will be done in the water or shore-land, (c)All vegetation and screening shall be hardy enough to withstand the travel of service trucks and similar traffic in areas where such activity occurs.PSE Response: Page 3 of 9 4 Boeing Apron A &B PSE Distribution Line Rebuild Project PSE Responses to Shoreline Utility Regulations 29-April-2014 Landscaping planned to compensate for loss of field grass will be native shrubs and will be located outside of traffic areas. xvi.A structure or other facility enclosing a telephone exchange,sewage pumping or other facility,an electrical substation,or other above ground public utility built in the shoreline area shall be: PSE Response: Not applicable.No electrical substation is to be constructed. (a)Housed in a building that shall conform architecturally with the surrounding buildings and area or with the type of building that will develop as provided by the zoning district and applicable design standards. PSE Resnonse: Not applicable.No utility building will be modified or installed. (b)An un-housed installation on the ground or a housed installation that does not conform with the standards above shall be sight-screened in accordance with RMC 4-4-095 with evergreen trees,shrubs, and landscaping materials planted in sufficient depth to form an effective and actual sight barrier within five (5)years. PSE Response:..Landscaping is not applicable,since this project conforms with the standards above. (c)An un-housed installation of a potentially hazardous nature,such as an electrical distribution' substation,shall be enclosed with an eight (8)foot high open wire fence,or masonry wall.Such installations shall be sight-screened in accordance with RMC 4-4-095 with evergreen trees,shrubs,and landscaping materials planted in sufficient depth to form an effective and actual sight barrier,except at entrance gate(s),within five (5)years. PSE Response: Not applicable.This circuit rebuild project is not installing a potentially hazardous facility like an electrical distribution substation. d,Local Service Utilities,Specifications: i.Electrical Distribution:New electrical distribution lines within the shoreline shall be placed underground; provided,that distribution lines that cross water or other critical areas may be allowed to be placed above ground if: PSE Response:This is not a new electrical distribution line;it is a rebuild of an existing line. (a)There is no feasible alternative route. PSE Response: Underground construction is not feasible,see PSE's response to section a.viii on page 2. There is no alternative source of energy aside from Paccar Substation to supply the 600 amp service to the Boeing Apron A &B areas.There is only one PSE substation with adequate circuitry in. proximity to the Renton Airport where Boeing's facilities are,Paccar SubstatLon.This substation is located east of the river near 1-405 freeway. There is only one alternate route to get a 600 amp distribution line to the west side of the river onto the airport property,and it is not feasible.A second circuit would be extended south on Logan Avenue (there is already one circuit there).This route would also cross the river,albeit in a more urbanized setting with a roadway bridge,commercial development,and it would be in addition to the existing 3-.......thphaseoverheadelectncaldtstnbubonhne.This new hne would run from Park Avenue North and 5 Street,west to Logan Avenue,south to the river crossing,then from the west side of the river north on Page 4 of 9 Boeing Apron A &B PSE Distribution Line Rebuild Project PSE Responses to Shoreline Utility Regulations 29-April-2014 the East Perimeter Road to a termination.Existing poles would be replaced in nearly the same locations with slightly larger poles and a second three-phase circuit would be added to the new poles. Double-circuit lines can be stacked vertically or laid out horizontally. (b)Underground installation would substantially disrupt ecological functions and processes of water bodies and wetlands;horizontal drilling or similar technology that does not disturb the surface is not feasible.PSE Response: A gaotechnical investigation would be necessary to determine if soil conditions would allow the horizontal directional drilling to occur without disturbing ecological functions end processes, (c)Visual impacts are minimized to the extent feasible. PSE esponse: Visual impacts of the proposal are minimal.Crossing under the river would provide the least visual impact.On the alignment of North 6'h.Street,the two existing poles near the river will be replaced with like-kind poles in the same locations,The existing pole about 180 feet east of the river will be replaced by a similar pole at a similar distance from the river.The existing single-phase wire crossing over the river is #4 ACSR conductor,with a diameter of 0.25 inches,The proposed three-phase wire crossing would be 397 ACSR tree wire conductor,with each wire having a diameter of 0,934 inches (plus a neutral wire of smaller diameter).While that is an increase in diameter,it should be considered that the wires will be about 30 feet overhead.At that distance,the size increase might not be noticeable.Furthermore,most pedestrians do not look up vertically but rather at maybe an angle of 20 or 30 degrees,putting the wires much further from the viewer and so decreasing the perception of an increase in diameter.There is an existing,larger telecommunications line below the electrical wires that will remain as-is.The increased wire diameter is for larger conductor and also a black plastic coating,which protects birds from injury or death if contact is made with the wires,Fixed "bird flappers"will be attached to wires over the river to reduce the chance of birds colliding with the lines. (d)If overhead facilities require that native trees and other vegetation cannot be maintained in a vegetation conservation buffer as provided in subsection F1 of this Section,Vegetation Conservation, compensatory mitigation shall be provided on-site or off-site. PSE Resoonse: Not applicable,since the existing overhead distribution line requires that only low growing vegetation be allowed underneath it.Rebuilding the line to three-phase would not add any further restriction for vegetation under the lines.There is one existing tree under the line on the east side of the river.It will not be affected by this line rebuild project•This tree has been trimmed to maintain safety clearances in the past,as is evidenced by its branch structure.

Project Description Boeing plans to improve North 6Ih Street between Logan Avenue North and the Cedar River,as needed for the Boeing Logistics Project.Improvements along N.6th Street and within the Shoreline jurisdiction include installing a sidewalk,extending the storm drainage system and adding a catch basin,installing two new street lights,removing an existing telecom utility pole, adding curb and gutter improvements,repainting channelization on the road,and adding a vegetated planting strip between the new sidewalk and N.6th Street (in an existing impervious area)(See Figure 2).New street lights will be added along the south side of North 6t"Street spaced approximately 70'apart,starting the southeast corner of North 6'h Street and North Riverside Drive.The street light poles will be in the 3-foot wide landscape strip,the luminaire will be about 35 feet above the ground,and each LED fixture will provide about 9,000 to 10,000 lumens. Also proposed is a five-foot wide,paved path connecting the N.6th Street sidewalk with the Cedar River Trail (See Figure 3).There is currently no crosswalk present here,leaving.A t*,!I I" pedestrians to cross Nishawaki Lane (Riverside Drive)in a high traffic area with c",|V IZ I'1 sight lines.The proposed trail connector wi;[require the removal of some of the ornarenta['.''

Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac April 29,2014 Page 2 shrubs and the installation of an asphalt pathway in an area currently composed of maintained shrubs and mulch. Concurrent with Boeing's plans,PSE is proposing to convert a single-phase,12.5 kV overhead powerline on North 6th Street into a three-phase line that will provide greater capacity and reliability for the Boeing manufacturing operations at Renton Municipal Airport (See Figure 1). The new lines will be larger in diameter (from 0.25 inches to 0.934 inches)due to a larger conductor and plastic insulation,which reduces the risk of bird electrocution.Project components within the shoreline environment include expanding the number of overhead lines from two to four,replacing two existing wood utility poles with like-kind poles but six inches larger in diameter,replacing the existing utility pole cross-beams to support the new lines,and installing a new underground vault and above ground meter cabinet for the expanded powerlines that will be placed underground on the west side of the Cedar River.Ground disturbance will be limited to the construction of the underground vault,which will measure 7' wide x 7'wide x 3.5'deep and may include and additional one foot of excavation to allow for gravel bedding and an additional one foot of excavation and backfill on all sides for a total impervious addition of approximately 64 square feet.The meter cabinet,which will be mounted on top of the vault,will measure 56"wide x 72"wide x 48"tall for a total volume of 4.1 cubic yards.The cabinet will provide weather protection for the meter itself and hardware for securing terminations for the underground cables.All other ground work will be conducted in areas that are entirely impervious,including the North 6th Street right-of-way and adjacent sidewalks.No removal of any trees or shrubs will occur as part of the proposed powerline replacement project. Total new impervious surfaces are anticipated to be 387 square feet,including PSE's utility vault west of the river and the trail connector/pedestrian walkway east of the river.To offset these unavoidable impacts,727 square feet of sparsely-planted,ornamentai landscaping adjacent to the trail connector will be enhanced with a dense,native shrub community. Additional areas of impervious surface (approximately 300 square feet)along N.6"Street will be removed and replaced with a three-foot-wide planting strip. To minimize potential avian hazards,non-conductive tree wire and non-spinning bird flappers will be placed on the new power lines.The bird flappers reduce the chance of birds colliding with the lines,while the tree wire provides insulation from electrical conductivity,reducing the risk of bird electrocution. Existing Conditions The project area extends along the south side of North 6th Street from Logan Avenue North to the terminus of North 6th Street,over the Cedar River to an existing utility pole just west of the East Perimeter Road on the airport property (See Figure 1).Only the western approximately 400 linear feet of the project area is located in the shoreline environment.Vegetated areas are Shoreline Environment Functional Effects Analysis I'uget Sound Energy %Andy l'advorac April 29,2(114 Page 3 limited to relatively narrow areas adjacent to the river.West of the Cedar River,vegetation includes mowed grass separated from the armored riverbank by lhe East Perimeter Road.The western riverbank is dominated by invasive Scot's broom and field grasses.The eastern, armored riverbank is dominated by a mix of invasive Himalayan blackberry,Japanese knotweed,and reed canarygrass and abuts a concrete wall approximately four feet tall. Between the concrete wall and Riverside [)rive,vegetation is limited to an approximately 70- foot-wide strip of sparsely-planted,non-native,ornamental shrubs and one ornamental tree. Fhe landscaped area is bisected by the paved Cedar River Trail.No vegetation is present in the project area east of Riverside Drive. Figure 1:Approximate Powerline Improvements Project Location *Figure depicts project area within shoreline environment only. Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac April 29,2014 Page 4 Figure 2:Approximate Road Improvement and Trait Connector Project Area *Figure depicts project area within shoreline environment only. The functions and values of the shoreline environment are extremely limited due to the existing conditions and the extent of the surrounding development.The project area lacks native vegetation,structural diversity,and special habitat features that would provide substantial habitat for resident and migratory animals.The ornamental shrubs present east of the river provide some cover opportunities for songbirds,but as non-native,non-fruit-bearing shrubs, they provide little forage opportunities.The high traffic setting creates noise and substantial habitat fragmentation,eliminating the use of all areas,except the Cedar River itself,as a significant migration corridor.The ornamental shrubs east of the river also provide minor reductions in stormwater flows entering the river,although due to a lack of herbaceous vegetation,the area does not possess significant potential to improve water quality by trapping and removing sediments and pollutants.West of the river,on the airport property, functionality is extremely limited,as the vegetation is rnostly rnowed lawn grasses that provide essentially no wildlife habitat value.Habitat function is further reduced as airport operations typically require removal of wildlife as an aviation safety precaution.The ability of mowed lawn to provide some level of groundwater recharge,surface flow reduction,and water quality treatment cannot be summarily dismissed;however,mowed grass does not have the vertical structure necessary to trap and filter sediments or to significantly slow surface water velocities. Shoreline F,nvironment Functkmal Effects Analysis Puget Sound Energy V.Andy Padvorac April 29,2014 Page 5 Therefore,the overall function of the terrestrial shoreline environment west of the river can be effectively described as minimal. Areas from Riverside Drive eastward along N.6"'Street are almost exclusively composed of asphalt and are subject to high traffic volumes.These areas provide no ecological functions related to the Cedar River Shoreline Environment. Figure 3:Approximate Trail Connector Alignment Functional Impact Analysis Replacing pervious areas with impervious (lawn,mulch,and sparse shrubs with asphalt and steel)always represents a functkmal loss.However,the areas impacted by the current proposals only provide minimal function,mostly related to groundwater recharge and a minor reduction in stormwater velocities.As described above,mowed lawn (and empty mulch)does not have the vertical structure necessary to trap pollutants and sediments or to significantly reduce stormwater vdocities.Therefore,converting such areas to asphalt,while representing a loss in function,does not reprent a substantial loss.The planter strip being installed adjacent to the N.6th Street sidewalk will represent an approximately 300 square-foot replacement of impervious asphalt with native shrubs.While the functional value is somewhat limited due to Shoreline Environment Functional Effects Analysis Puget Sound Energy %Andy Padvorac April 29,2014 Page 6 the separation from the Cedar River by Riverside Drive,it does provide a minor functional lift for water infiltration within the Shoreline Environment as compared to the existing condition. The habitat function provided by the impact areas is also minimal,with mowed lawn providing very low levels of function.The ornamental shrubs provide some cover for songbirds,but the relative lack of density and the lack of fruit-and nut-producing,native species severely limits the forage opportunities for wildlife.None of the shrubs proposed for removal do,or ever will, provide shade,detritus material,or large woody debris recruitment for the Cedar River.By mitigating the impact area at a ratio of approximately 1.9:1,while improving the density, diversity,and species composition of the shrub species present,the post-project area will represent a significant increase in wildlife cover and forage opportunities beyond the existing conditions.These functions are particularly valuable in dense,urban settings,as refuge areas are not typically available and are highly valued by wildlife. The visual and aesthetic impacts of two new electrical conductors is insignificant,as they will be in a similar location as the existing lines and will be on a parallel,horizontal plane.The non- spinning bird flappers and tree wire will further reduce the risk of birds colliding with or being electrocuted by the transmission lines.Similarly,the addition of two new street lights will not represent a significant impact,as the area is already heavily developed and the existing terrestrial habitat is severely limited. The replacement of the impervious areas adjacent to the N.6th Street sidewalk with native vegetation and pervious soil will help minimize the impacts associated with the new impervious surface from the utility vault and the trail connector.This,combined with the substantial increase in relative wildlife habitat functions associated with the installation of a dense native shrub community as a replacement for sparsely-planted ornamental shrubs, mulch,and mowed lawn,leads to the conclusion that the totality of the proposed plan represents no-net-loss of ecological functions in the Shoreline Environment.
