II r ~i 5helley Lake Qraft EJ5 Vrif I February 1994 PROJECT SUI Y►►YLAR7 PROJECT SUMMARY OBJECTIVES The proponent proposes to rezone 14 acres of the 123.8 acre project site from Urban Residentiai-3.5 (UR-3.5) to Urban Residential-12 (UR-12). The remaining area would remain zoned UR-3.5 and Suburban Residential-1 (SR-1). A Planned Unit Development (PUD) overlay with bonus density is proposed for the entire site, allowing development of 459 residential dwelling units. A diversity of housing types would be provided including 195 multi-family units, 68 manufactured homes on platted lots, 158 conventional homes on small lots, and 38 large lot single-family homes. The PUD proposed would create a fairly private residential community encompassing a variety of parcel sizes and housing densities through the provision of clustered lots. The PUD overlay will also provide substantial areas designated as open space. The project site contains sensitive areas such as Shelley Lake and its associated wetlands, sloped areas, and wildlife habitat. By utilizing a PUD concept these areas can be protected, enhanced, and managed to control and limit further degradation and actually improve existing conditions. The proposal's objectives are summarized in the following statements: • Develop a planned residential community that is compatible with the surrounding neighborhood. . • Provide substantial open space areas to protect and enhance the site's sensitive features. • Enhance the wildlife habitat areas associated with Shelley Lake and Saltese Creek to promote their ongoing health and viability. • Minimize off-site impacts caused by project development and increased population on-site. • Provide a density transition between the multi-family units and smaller manufactured home lots to the north and the larger nearly one acre lots to the south. • Provide a variety of housing opportunities to meet a growing market demand. ~ Provide paved roads and through connections and minimize off-site road impacts. • Provide an aesthetically pleasing environment which will enhance the Shel%y Leke Oraft ~ Februery 1994 adjacent neighborhoods. • Provide restrictive covenants and controls that assure quality control of architectural considerations, landscaping and maintenance, place restrictions on domestic pets and livestock keeping, and assure ultimate protection of the environment. • Provide a residential community where residents can live in close proximity to the natural environment, yet restrict their activities to - respect the needs of wildlife sharing the site. • Minimize conflicts with wildlife habitat while providing project residents with on-site recreational opportunities. • Promote awareness regarding the site's sensitive features by providing educational materials to residents outlining efforts concerning protection and enhancement of these features'. PROPOSED ACTION The proposed site is 102.8 acres of undeveloped land and 21 acres of surface water (Shelley Lake) totalling 123.8 acres. The site is located in the Spokane Valley, approximately 1,300 feet east of Sullivan Road and approximately 600 feet south of Sprague Avenue. A PUD plat of 459 residentia,l dwelling units is proposed with a rezone of 14 acres to UR-12. The majority of the site would_ remain zoned UR-3.5 and SR-1. Bonus density is applied to the UR-12 and SR-1 zones. The site is in the Urban and Suburban(+) categories of the County's Comprehensive Land Use Plan. The Urban category calls for residential densities between one and 17 units per acre. The Suburban(+) category calls for residential densities of between one and five acres per dwelling unit. The overall site density proposed is 3.7 units per acre, with proposed densities per zoning classification as follows: UR-3.5 at 2.90 lots per acre; SR-1 at 2.09 lots per acre; and UR-12 at 13.93 units per acre. The proposal includes a density transition between the multi-family units and smaller manufactured home lots on the north and the larger one-half to nearly one acre lots on the south. Open space is designated for 37.9 acres to provide buffer areas and protection for the lake and Saltese Creek shoreline areas, slopes, drainage areas, and wildlife habitat areas on-site. The proposal includes plans to enhance the existing habitat areas, while providing a soft pedestrian trail system, educational materials for residents, and designating areas for possible future beach, dock, picnic, and community center facilities. A future community center, if proposed by the homeowner's association, would be located within the retrofited former meat packing facility. Future beach, dock, and picnic facilities would be located at the northeast corner of the lake. She/%y Lake Dieft 2 February 1994 The interraal road system will cansist pf a cambina#ion of paved puhfic and priuate PUfl roads vvFth primary access ipoints at Cvnklin Road ❑n the north and Rptchfnrd priWe on the south.

TFae prvpvsed rezane to llR-7 2 and PUD overray for the entire site would nat accur. This would allaw the development of 225 buildable parcels, slightly Iess than half the 459 - unu#s prvpvsed. Under this alternative rfladway cnnnections cauld occur at Sfnamrock and Galway Streets, RQtchford Orive, and 4th Avenue, increasing traf#ic cnunts vn a!I of these roads. All rvadways would be developed to public standards. There would be less demsnd fQr publie services than fvr the propvsed action afternative due tv fewer resir#enCs being Entroduced into the area. Fewer pea,ple would result in less traffic, school children, and lawer amflunts of imperviaus surfaces. Withou4 the PU D ouerlay there would be iess area designated as opera space, affarding less pratection to sensitive features and habitat areas. Na enhancement af wzfdlife habitat areas would accur and #here would be nv additianal restric#ions Qn their aase. A hvmenwner`s assvciatian would not likely b~ formed, eliminating the cestrictiVe cavenants praposed cvntrolling aesthetic and wildlife impacts. No educational or recreatianal Qpportunities would be providsd. I No-Activn Alternative I This alternatiVe would totally preclude any development at the project site. Existing cflnditians would remain an-gaing. 7he positiae impacts an wildlife habitat areas discussed as part vf the Propased Action would not accur.

NATURAI ENVIRDNM'ENT 9.0 Water Shelley Lake's fairly steep sides, gradelly sail types, limbted visibifity, and high degree vf water lever fluctuatians have aII contributed ta, its lack of aquatic Vegetativn. The current water quality has been degraded by u,p-stream arrd pvssi6ly un-site agricultural , prac#ices. Fertilizers and pesticides have artificially increased nitrvgen and phosphvrus le►vels. Peat mining vperatians in the Saltese FlatsG have added substantially to organic particulate matter inflaw, which when decvmposed depletes dissalved vxygen supplies. Anaerobic Gandrtivns have !ed to frsh kills, reduced visibifity, and Qdars. - The addition vf imperiaus surfaces will change ~tFae directiQn arrd speed vf an-site surface water. If na# managed prv,perly the remaval of undesirable Vegetatien and disruptivn o# svil could add to the amount of cvntaminants and sedimenx reaching the lake.

Plants and Anima'Is Site deyslvpment will likely encroach upan existing natural ha6itax areas used by • waldli#e. The PLJD design allaws for pro►rision of open space tv protect sens+tive habitat areas. Restricting domestic pets, livestvck keeping, and herbicidel pesticidef fertilizer u5e will reduce their impact vn wildlife habitat areas. Most of the undesirabIe knapweed will be eliminated. 59hareline areas vn either side of the saft pedestrian trail wili 4e enhanced by plar~ting of vegetativn v►rith high Value to wiIdlife. New trees, shrubs, ansi grasses will be irwtroduGed to the site #ar fovd, cawer, and nesting. Minimum landscaping standards will be established in ihe restrictive covenants. These will stipulate the ty,pe of Iandscaping permitted in the transitinn zvne between native and culti►rated plantirags fvr lots af'ang the lake`s shoreline. Educatianal materials cvncerning habitat enhancement efforts will be prvvided tv site residents. BUILT ENV'IRDNMEN7 1.0 Land and Shvreline Use The existing agricultural arad rural fand use character of the site wau€d bs altered due ter the introduction of urban densiti$s and public services. The prapased actian prgvides a density transitipn hetween the higher density manufactured harries and multi-farrtiily units to the north and the Iawer density large acreage Ivts to the south of the site. Project design inciudes a 50 foot setback of Ivts frQm the lake's o rd4nary hig h watee ekeVatian, prorriding approxirryately 100 feet of separation between the lake and hausing structures. 7herefore sorne of the horones wilf be within the designated 200 foat shvreline area, requiring a Shvreline Substantial DeyelQpment PerrrEit. Canstruction of a wavden bridge for crossing the soft pedestrian trail oVer Saltese ,ShePley tske Draft 5 Fe,bruary 1994 i ~ ~ Creek and the trail itself will alsv require this permit. A future community dack and development of a beach area would aisn require this permit ut propvsed by the hvmeowner's association. The project will campEy with aII the policies and requirements flf the 5harePrne Master Pragram. I' The majarity of the site is zaned UR-3.5, with alppraximately 20 acres.zoned SFt-1. A zvne change to UR-7 2 far 14 acres currently zo'ned UR-3.5 is prnposed, with a PL1D Qveriayr far the entire project site. Bvnus density wnuld apply to the UR-1 2 and 5Ft-7 zanes. The zone change to UR-a 2 wauld al1aw d"euelo,pment of muIti-family canits nn the nvrthwest corneR of the site. 9onus Density Points haVe been earned by designing the PUO to rriake special provisivns for common operr space, envirvncnental cvncsrns, public ser►rice and facc#ity availahifrty, using a design team, and praViding a araix of housing types. With the prvpased zoning and PL1❑ overlay with hvnus density, the allawable mumber vf Iots could cvnceiyably be 672, although vnfy 459 are proposed.

T'he plat vuill be develaped in pha5e5, vvith 58 units cornpleted by 1935 (Phase 1) and the remaining 409 units completed by 2000 (Rhase 2). A traff ic analysis was shelley Lake ❑raft 6 ~ Februasy 1994 I prepared to address traffic gensration, levels Qf serVice, and the need for imprvvements to mitigate impacts. At futC build out there wgutd be a projected 3,750 Vpd, with appraximately 283 AM peak hvur trips and 375 PM peak haur trips. 7he largest peak haur generated traffic accurs in the PM when 246 vpd vvilF be entering th8 51t8.

Althaugh these intersectivns are currently on tfie margins, there is capacity fnr additional westbourid and narthbaund mvvemerrts. •Shauld the oVerall deuefopment and grcaw►th af the area ~be maintained at nearfy 3.0 percent, two af these intersections are expected to fail priar to deuelvpment nf this prvject; 5ulyiuan and 4th (LOS F) and 5utlivan and 'I Sth (LO5 F), This is due to westbvund to ravrthbound lefts and higher through VnlumeS, • After the cvmpletion of Phase 1, a11 study intersectians are expect+ed to remain at the same background Ievet of service ss prvjected. This does not mean that this deVelopment will not add addit'ronal vehi+cles to the transportatinn system, only that the intersectivns far 1995 have the LtlS capacity for t'he +ncrease in backgrnund tra'Ffic and the devefvpment of Phase 1, • . • With the completian of ful1 build vut of Phase 2 by 2004, sevsral iretersectivns will need rmpravements to allow the vvlume af anticipated traffic to pass at reasvnable IeVels af service. SuCEivan and Sprague, due to the design of the plat directing trips to Sprague via Conklin during the PM peak hour (by adding 89 - 90 left turns frvrn this project, added to the 1995 expected 424 existing PM peak hvur left turns), will be pushed beyand its capacity to serve left turns. AdditionaG4y, the Sprague and Canklin intersection during the PM peak hvur ►i+rill drap to an LOS of EIF, with LOS E heing the minimum standard for an vnsignalized antersec#ion. Althvugh the additAan af 58 single-family homes in Phase 1 and assaciated traffic will cantribute to the existing tra€f ic cu rrently using the Sullivan Road and 5prague Avenue corridvrs, the Qniy impact will be that towards the cumufative average daily traffic valurraes. The prapased develapmeni wiil not have any significant impact to leaels caf service thraugh the de►►elvpment uf Phase 1. Spokane Cvunty has identified leVel vf service as the iradicator far prvhlems assaciated with deVelnpment and, therefvre, based 5o3e1y on LOS thiS project wili have nn impact. Hawever, su'bsequent deveIppment vf this plat in canjunetivn wit'h development in and around this area will require the imprvvement of several strests and rvads within this gerrersl area pf Spakane Cnunty. At the request vf the Spvkane Transit ►Authority, a future transit Shelley Cake 0rafr 7 FBbruery 1994 i stap and shelter area has also bQen resen►ed. Tihis area is lacated an the south side of 4th A►►enue, adjaeent ta the proposed multi-farriily area, just west of Can nery Raad. At the completsvn of Phase 2 a traffic signal may be warranted at the intersectian of 5prague Avenue and Cankl'rn Raad. 7his signal wauld be necessitated by a combination of factvrs including the cantinued area develvpment and grovvvth excl~a5iae of ihe 5'~elley Lake prr~jsct and tlne addition of tM~e Shelley Lake vo'Jumes. Hawever, this signal should be instalfed when this intersec~tiQn meets at least four warrants for signa'lizativni as nutCrned in the Manual ~f Uni#Qrm Zraffic Contrvl Dedices {MUTCD).

Due tQ the number of prflposed developments a'long the 5ulfiVan Raad corridor, id is - unclear wnether develapment of the praposed aciEivn, would require the impraVements recammenaled due tv develvpment of this project alone. Vllith the vther propvsed ' developnnents along the Sullivan raad carridor, these impcovernents are cecammer~ded and required in some instances to aflo►rv through traffic progressian. However even with the development of the SuNiVan Raad corridor, the devefvpment of Phase 7can be umplemented wi#hau# having a significant impact on the overall area transpvrtation Sy►5'[eEfl. 3.0 PubEic Services An additianal 459 residences will be added to the responsibility of aistrict No. a of the Gcaunty 5herlff's Department. The added population will increase the rrumber of peaple requiring service and the number of crimes cammitted. Prv}ect design makes Ratchfvrd Drive a collector arterial, which places homes alvng Ratchfard in the 19% pvtentia1 crirne rats categvey with an increase fraim the currently existing rate of 15 The rate at these hames would he equal to the o~rerall a►rerage. However the private commvnity type of design propased, which includes only two access paints inta the development and perimeter fencing, typically gerierates less calls for ser►rice than the grid type o# street design. The development will nat be gated. Many of the upper- inc4me hflmes will have resvurces to instaff 'indiVidual security systems. The fvrmativn of Black Watches will be encQUraged. Approximately 274 schoal children are projected at fuff build aut of 459 residences. The increase will be gradual based on an ei'ght-to ten-year development with apprvximately 34 new students per year. Adarns Elernentary and Gr~eenacres Junivr High are nearirrg capacity and vvill be ir~pacted by the sddition of nevv students from this and ather residential de►►eIvpments. TherQ isj adequate capacity at Central VaIley Fiigh. However School District No. 356 needs tm compEete their existing expansian plans and requests that the devetoper negatiate a woluntary agreemenx to hQlp rnitigate #he prQposal's impact on pubfic schools. The new residences will increass the demand for park space and facilities, with mast Shelley Lake !?raft 8 Fe6ruar}• 1994 of the impact occurring on arganiied spvrts facilities. DeveQapment of the site will preclude 5helley Lake's acquisition by the Caunty Parks Departrraent as recomnnended in their 1989 Pfan. Recreativnal oppvrtunities will be pravrded by the prolect, including a soft pedestrian trail surraunding the lake. Areas are designated fvr #he future development of picnic, heach, dock, and cvmmunity center faci1i#ies if prraposed by the homeowner's assaciativn. On-site act'svities may include wa3king, jagging, CrUS$i-COL1ntry SICi3S1g, bir+dfwifdlife observa#ian, fishing, swamming, ice skating, and rvwing and canoeing. The developer will be requzred to sign a dactiment agreeing ta future mitigativn measures impvsed by the 13oard af Cvunty Gvmmissianers that help " alleviate impacts ta the Caunty Park systern. An additional 459 residences will be gradua3ky added to the respvnsibitity of Spakane Cvunty Fire Protection District No. 1 vuer an eight-tca ten-year huild aut periad. This may result in an increased need far additional manpawer and equFpment in the area. Fire hydrants will be located throughaut the ,prvject site and supplied by adequate fire flvws. Restrictions will be placed on the use gf nvn-fire retardant building materials and wvvd shake rogfs.

(see Figure 2). - A reaone to Urban Residential-I 2(11R-1 2) with bonus density is propased tor 14.0 acres vn the west side of the site trr alivw far the deaeioprnent of 195 rnulti-family vnits (see Figures 3A and 3B). 5+ngle-family residential lats will include a mixture ❑f hausing types including 68 manufactured homes on plat#ed Ivts in #he narthern area of the site, 158 conventivnal homes an small IQts around Shelley Lake, and 38 large Ivts on xhe site's seuthern partian. The prQponent's abjective as to create afairly pri►►ate residential cammunity vn a site #hat is currently undevelvped, with avariety of parcel sizes ranging frvm approximately 6,000 square feet to 41,000 square feet, and approximate6y 37.9 acres of vpen space. The owerall site density propased is 3.7 units per acre. Propvsed densities per zaning classification are as follows: L1R-3.5 at 2,90 lats per acre; SR-1 at 2.09 Iots per acre; ar~~ UR-1 2 at 13.93 units per acre. The minimum tot size fnr the UR-3.5 zone with aPlJD overlay is 6,000 square feet, vvith an vverall maximum derasity of 3.5 dwelling units per acre. 1N~thin the SR-7 zone the mirrimum lot size is 15,000 square feet with a PUD overlay, pr+ovided the aWerall density dves not exceed ❑ne dwefling unit per acre. The zninimum lot size far the UR- 12 zane with a PL1D aaerlay is 800 square feet, with an +vverall rinaximum density of 12 dwelling units per acre. These maximum densities can be exceeded thrvugh applAcativn of honus density ,pravisions. A total of 1.95 units per acre of banus density can be earned ►rvifih the proposed PUQ design and applies to each zvne - classificatiorr. This results in a tataf a# 672 units allowed fvr develapcnerat, although anly 459 are kteing propQSed far full develapment of the praject site. Full build-vut of the prvposed develapment is expected tv take place v►►er an eight tv ten-year period, depending vn hvusing market cnnditions. The prnject site wiAl be develaped in phases, starting with improvements and constructivn in the northern area and praceeding sovth. Appraximately 50 hDmes are expected to be constructed per -year based dn current market cvnditivns. The proposed preliminary PU[3 plat has heen designed Rn an ef#ort ta keep i gnvirvnmental impacts to a minirnum.

The o,psn space areas wa11 be prvtected and restricted frvrrti future de►►elapment. MethQds ta enhance the existing wildlife ha'bitat areas will include planting vegetativn of high value tv wildlife alang the shnreline, remnving a substantial a mount of intraducsd weed species, and prvviding educational materials to residents cancerning wildtife enhancernent pragrams. - Develapment of the projeet site wEtl impact the existirrg external transpartation system within the Vicinity of the site by adding population tv a previausly unimhabited sFte which wi31 generate traffic. This propvsal createsi new roads within the site to access the lots and provide ingress and egress fram the site. The majarity of the roads will be priVate, except fvr #he ext+ensian of Rvtch#Ord ari►►e narth tfl 4th Avenue and Canklin Road. All the roads will be paued and built accvrding ta +County Engineers standards for public and private PU❑ roads. Access to the develvped site is prvUlded by Conklin Road tv the narth, 4tri and 'I fith Avenues ta the west, and Ratchfard Drive ta the sovth. The Caunty Arterial Rvad Pian designates the app;roximate limits of the vld Milwaukee Railroad right-vf-way as the future extensian of the Sauth VaIley Arterial. At this time the ►4rferia!

Fire fighting services will aIso be enhanced due to the inclusian of fire hydrants and an adeqaaate water supply and pressure sys#em orr the site. All private roads with iess than 30 feet o# paved width will be designed with a 30 fvot inside curb radius on corners instead flf ihe standard 20 #aat radius. fihis will pravide adequate turning radiuses for the D+strict's ex7sting and propvsed larger f ire en gines far ease of mvvement within the site, Access to the site is praVided on the north and south to minimize response times far emergency vehicles. Pvlice pratection within the area is provided by the 5pvkarae Gnunty 5heriff's department. Since the site is largely undeveluped, there tras nnt been a great need for police services in the past. The intrvduction af 459 hausing units wiii increase the demand fior palice pratectivn. The praject site is lacated within Gentral Valley 5chool Qistrict No. 356. The schaals serving the site are Adams Elementary, Creenacres Jre High, and Central Valley High 5chavl. The elementary and junivr high schvols are at maxir~um capacity. The added populativn to the area would result in new students generated fram the site. The increase would uccu r gradua lly ovea an e9ght to ten-year perivd d u e tv prfljecx phasing.

SHELLEY LA'KE PFtEU1VIIfYARY PU'D PL.AT r ENVIFtONMENTAL IMPACT STATEMENT , , 11 REASONA13LE AL TfRNATIVES Two aIternatiaes to the prvpased actiQn to rezone and develap 5hefley Lake are also given considerativn. They include: 1) Qe►►elapment Under Existing Zoning, and 2} a Na-►4ctian alternati►re. The fvllawing is a general discussiora of impacts regarding these twv alternatides. 1.0 DEVELOPMENT UNDER E}CISTING ZONING If the prvject site was allavved to dedelvp under the existing zaning, the proposed rezvne to LJR-12 (Urban Residentia}-1 2) and PUD vverlay fvr tFee site would nvt occur. The site would remain zvned L1R-3.5 (Urhan Residentiai-3,5) and SR-1 (Suburban Residential-7 This would allow the site to be segregated intv 10,000 square fuot minimum parce€s for areas anned UR-3.5 and one aere minimum parcels far the 20 acres zaned SR-1. Maximum densities #or these areas are three and Qne-half dwelling units per acre tUR-3,51 and ane dweliing unit per acre (SR-1 A cflnceptual layvut plan fflr deveiapment under existing zoning using tFrese densities is presented as Figure 4. This alternatiye wvukd aIlow the d'evelvpment vf 225 buildahle parcels an the site, slightly less #hsn half of the 459 units praposed. This lawer density wuuld most likely result in ivwer quantities af impervivus surtaces than that prapased, due to the develvpment of fewer housing structures. HnweVer this alternative wvuld be develaped with aII public raads, vvhich are vvider than the mastiy private rvads inctuded in the PropvSed Activn aiternative. If there are Ivvver quantities of imperuivus surfaces, then less storm water run-off wauld be generated by this alternatiVe. MoweVer a master covrdinated sto►m vvater management plan for the entire developabls area may not be prepared vr irrmplemented. This type of plan w'ri'a ensure that storcn water run-aff and cQntaminants dv nvt t3ischarge to tYre lake from surrounding urhan areas. li the praperty were to he suhdiVided, the applicable staradard from the Cvunty's Shvieline Pragram is a 200-fovt structural setb~ck unless a 5ubstantial Develvpment Permit is a'htained. If the land were to be segregated via exemptiam trom the su'bdiuisivrt regulativns RCW 58.17, then oney a 50-fvvt setback fram #he ordinary -high water mark would be applicable. peVelDpment under existing zaning cvuld include raadway connections at the existing termini at Shamrvck and Galway Streexs, RQtchfiord arive, and 4th ►4venue. This wauld increase traffic counts an these rvads and impact a greater number vf residents in the adjacent Rvtchford Acre Tracts to the sauth. Hvwever these roadway cannections would tend to disperse traffic thrvughout the residential area rather than concentrating ttaffic vn RQtchfvrd Drive. Also less tQtal trips per day would be ' generated frvm the site with only 225 residenGes instead af #he proposed 459. A11 raads wnuld be developed to public rather tFaan mostly private roadway standards. Shelley Lake Dref,t E15 18 February 1994 i There would be less demand far public serWices hn this area due tn the decreased numher vf dwelling units and associated population. With sparser deuelopment, the schoa1s sen►ing the site would haVe Iess demand placed on them far educational - serVices. HoweVer the school district would still' nsed tv prvvide bus serVice ta this area tv accammodate the relatively few childrenEraeeding transportatian to and from schovl. There would alsv be less dsmand fQr police and fire fighting services due to the lower papulativn levels. The increased number nf transpvrtation access p8ints would decrease eesponse times to the site. ~ Lower population Vevels than thQSe proposed with the zone change and PUQ overlay would at first appear ta Fesult in less di5turbal,nce to wildlife and hahitat areas. Hawever without 'the provi5ion5 pf a PUQ over Iey ione, there would be Iess area designated as vpen space, affvrding less pratectiQn to sensitive habitat areas. In additian there rnay be few provisians regardirrg future devekopment of these areas and no site specific restrict+r►e covenants to gvVern tkeir use. A well coordFnated plan far weed cnntrol a1ang the lake's shoreline may na4 be irrtplemented. A wildlife habitat enhancement pragram would nat be developed and there would nat he any coDrdinated effflrt ta improve the vaater qua#'ity 11ar stabilire water quantities rrvithin Shelley Lake. ~ The devefapment under existing zoning alternadive may not include the fvrmatinn vf a homenwner's associativn ar restricti►►e cover~an'ts. This would aesthetically impact the area by nat gaverning paint and fence colors, types, and Ivcatians. TihEre would he no perimeter fencing or berms with landscaping creating a priva#e cornmuraity - fee'ling and rncreasing security. There may be nv covenants guiding landscaping _ practices with wildEife habitat needs in mind vrlipreVenting disruption 6y domestic animals. Large animal-kee,ping could alsa he allvw,ed because it is permitted within the - SR-1 zone. There would be na coordinated educativnal prvgram targgting area _ residents concerning the site's sensrtive enWironments. Recreativnal opportunities would be limited with this alternative. No trail system, cpronmunity center, swimmfng beach, or picnic area would be provided. The diversity in housing nppartunities would be iast with implementation vf this alternatiVe. 2.0 ND-ACTION ALTERNATIVE The No-Action Alt~rnative would tofially preclude bny development of the project site. Existing canditivns would essentially rerriain an-gaing, including current agricultural prnduction. I ~ There would nat be any innpact to puhlic services if the praperty did, nnt develop. Additional schvo1 capacity, busing, and fire and police protecfion serUices would nat be required. Utility and rvadway extensions onta and throughout the site would nQt Qccur. There would be no increase irr aft-site traffic generated by development Qf the site. The lack of fire hydrants would result in les I 's tivater available at the site for fire fighting purpQSes. II ~ , SheIley [ake araft EIS 19 February 1994 There would be na add'itianal im;pervimus surfaces added ta the site. 5torm water run- vff generation would remain unchangedr however existing trnpacts to 5helley Lake that may be caused by agriculturai prvduct run-oft di.e. pesticides, herbicidesl would CC1fltI11lJe. The pasitiVe impacts nn witdlife and wildlife habitats vutlined as part af the Prapcrsed ►4ction would rrnt vccur. The lake would cantinue its vvide water Reael fluctuatinns and would prabably continue to be seVer$ly impacted by suspected upstrearn land use actf►►ities. Nv caordinated effvrt would take place to enanage the existing water quality and quantity af Shelley Lake, which would substantially improve its fishery resourees, aegetatide and wi[dlife species di►►ersity, recreatian patential and aesthetic appeal, as well as improve the waters far aquifer recharge. Hower►er, the lacfc of peQple would rsmove any poten#ial for encrnachment an exrsting wildlife and vegetatiVe cammunities. The recreational oppartunities included in the Prvposed Action alternative would not be provided. Access to the site Fs curreratly restricted by the prvperty owners and na permitted recreational opportunitiQS take place an-site. The Iack 4f residential deuelop ment wQUld cvntinue the possibility af f uture purchase hy the Spvkane County Parks Department, as outlined in their future acquisition plans. Howe^ver there is a severe lack of funding for park property acquisition and additionaf funds would be required fvr prQperty maintenance and water quality impravements. If park acquisition vvere tv occur, Courity improVements may weli be Eimited corripared ta thvse praposed by this project. F9oweVer, recreativnal apportunities at the sfte would be auailable fvr vse by aFl County residents. 7here is nv public benefit pravided by delaying or precluding residerrtial development of the praject site, lrlrban services are availahle ❑ra adjacent prapertaes and the propased project would prvVide road cvnnections and urban ser►►ices tn the area. Atlditianal public benefit would be provided by improving the qua'lity of dhe lake and prvVidirag ivng-term protection ta the wetiands areas. The site's 5ensitirre habitat areas would be enhanced and maintaFned thrvugh ihe homeowners assocFativn. Shelley Lake l7rBft E15 20 Febrcrery 1994 M. AC TEA'NATIVES GONS1DERED During the sevping pracess and prsparation of this enVironment impact statement, several alternatives regarding sits road design and access were identified. The project sponsnr rejected these altematiVes because ihey are incansistent with project vbjectives, as welf as with cmrryments received frgm neighbarhaad residents and the general public during the scvping period. 7hese alternatives were determined to have seve raI flaws i n+clud ing econvmic feasib ility, p robkerns assvciated with acquirin g right- af-way oUt51de xhe pfat baundary, difficulties in developing roads in areas wvith geologic andl hydrol'vgic constraints, inconsistency with the spvnsar's gnaf of praviding a private residential community, and incansistency with the defsires of adjacent residents to prevent additional traffic thrvugh thsir neighbarhoad. 7hs altematives eliminateti from #urther analysis are described in genseal form belvvv, including identification af the fIaw or fiaws, 13oad "N" Eirtensian - Rvad "N" as presented during scoping w►auld be a through extensivn a# a public rvad to the east property line. This rQad +vvould 1ine up with the parcel lines of the certificate af exemptians which haVe been pre►►iously a ppraved on property adjacent to the east vf the prvpased plat. This afternative was rejec#ed and the site rvad design was reWised due to the lack of any future roadway Connection5 to the east of the project site. The only pvtential raadway connection to the east would be a cvnnection to Steen Rvad, which is a northlsvuth IQcaI access raad that terminates south of 5prague aVenue. f]ue to the existing tnpvgraphic relief of the area, extensivn nf Road "N" fram tha eastern plat bvundary to Steen would prove to be difficult and expensiVe. The Arterial Road Plan identifies intersections at one-mi6e intervals in association with the future construction af the South Valley Arterial. Steen Raad is on #he dhree quarter-mile and, in arder to be consistent with the Rrterial Road Plan, traffic would likely use 4th AVenua to cannect from 5teen to Flvra Road where the inte rsectian with the 5o uth Va11ey Ar°terial is planned. 4th Avenue Extensian - This alterrrative wvuld require extending 4th Avenue as a cvllector arterial straight thrvugh the plat to tihe east praperty line, for futtare cannectivn to Steen and FIora Raads. As with t'he Road "NA Extension, th9s altecnative is determined to have several prvblems. Any extension of 4th ►4venue east vf the site wvuld be expensiae due to high engineering and constructivn cvsts. A grauer pit exists north of Shelley Lake and east Df the site in the path vf the 4th Avenue alignment. Extens7an of 4th Aaenue to the east to eonnect to 5teen and Flors Roads would likely necessitate constvuctivn vf 4th Averaue around the narth side of the gravel pit. The gravel pit is connected to Sattese Creek by a drainage channel and acts as an emergency flverflaw far Saltese ' Creek and 5hefley Lake. The drainage channel and gravel pit need to be preserved as averflaw nutlets for the future as required by 5pakane County Engineering staff. The gravel pit nriusC be considered in any extensivn of 4th Avenue to tFae east vf the plat. Shefley Lake !]raft EIS 21 February 1994 I 6th Avsnue Extensfon - This altematiVe vrrould require extending a raew rvad, outside plat boundaries, fronra avtchford arive w$st to Sullivan Raad.

N Althou gh thEs alternatiye caufd prvvide an additiohal eastlwest access ,point to 5ulliuan Road, there are seVerai prvblecns assQCiated with it. The frrst probfern is that access to this pvtential right-af-way would have to be obtained #ram the Centra! Valley School Qistrict, as the property is owned hy the f]istrict and lies vutside af the prelirninary plat bvundary. 5ecandly, although a new access to SuF7iVan cvuld reduce the numher af Vehicles utilizing 4th Avenue, additionat rignt tums fram Sth Avenue vnto SulliVan would~.~duce gaps in traffic at the 4#h AVenua iratersectivn, further degrading the o,poratinn of the 4th AvenuelSullivan Rvad intersectian. Adding additional traffic an Suflivan Rvad wvutd also further degrade operation af the Sullivan Raatfif5prague AVenue inter5ecfion. Conklin Road Temparary CanneGti'on - This alternatiVe cvnsists af aternpvrary thraugh cannection to Sprague ►4aenue via Cankfnn Rpad, with nv direct access to the 5auth Valley Arterial. This alternative is cansisterat wath the Arterial Road Plarr since CQnklin Rvad does not Ise at the vne-mile interval as identefied in the Plan. Quring the scaping process se►veral pvssible 8It@FR1atiVeS were evaluated fvr improvements to 5ullivan Raad. One of these optivns inVQlved utilizing Conklin Raad as a temporary relief for project trips having to access 5ulliuan flnad. This cannection to Sprague wvuld be remvved by installatiQn of a'Cul-de-sac fQilvwing constructivn of the f uture Svuth Valley Arterial, as ihe existing Cvmprehensive P[an d aes nat identify an intersection at the vne-half mile at Conklin Road. - Based on several recent studies af the Sullivan Road and S,prague Avenue cvrridvrs, far traf#ic within this general area to adequate3y access 5prague AVenuee an additivnal Eink east of 5ullivan Road will need t4 be prvvided,'. Studies that were pro►►ided #v the County indicated that any nevv residentiaf traffic, as well as any sxisting res'rdent+ar traffic, that could be removed grom the SulliVan Road carridor and rvuted directly to Sprague Avenue will help Sulli►►an, nat nnEy in the short term but also in the lang tecm. Therefore, considering the high costs far reconstructing the 4th Avenue arad Sulli►►an RQad intersecdion, ths sponsar's preferred alter natiVe far this prvject is to directly aGCess Sprague Avenue and the future Sauth Valley Arterial. Any tempvrary through connection to Sprague ►4,uenue r►vas rejected by the spansor since a tempvrary +connection wauld not prQ►►iste long term refief for Sulffvan Road. The alterna#ive af praViding an easterly connectian to Steen and FImra Rvads would be expensiVe and beyond the spQnsor's cantrol and the scope vf aihis project. Shamrock Str"t Eartensian - This alternatiVe would reqvire extending Shamrack 5treet north frvm the existing temporary cul-de-sac within the Rotchfard Acres plat directly irata the 5helley Lake pla# and cannecting to Road "N." 5helley Cake ❑raft EIS 22 ' . Februery 1994 The pref'iminary plat exhihPts presented at the scoping hearing shawed this cmnnection ta Road "N." Ducing the scaping hearing, Caunty presentativn artd testimvny indicated t'hat the primary through cannection between the iwo plats would be the - Rotchfard ❑rive and Conklin Road cannectian, vvith patential access at Shamrock 5treet prvuiding a secvndary connection point. Substantial public testimony ravalved araund this issue, with cammends indicating that na cannectian w+auld be desirable tv _ the residents in tFae Rvtchfard Acres plat. Therefare, the cannection of Shamrock 5treet to Raad W was remvved. However ta improve northPsauth circulatipn east of SuElivan Raad, the Conklin Road and Ratchford DriVe cannectian was maintained. The extension +of Shamrac'k Street thrvugh the project to cannect to Road "N" would Chave the effect af daspersing traffic in the area, therehy reducing traffic an Rvtchford Drive and impraving neighborhaod cantinwity in the area. The spensar's gval of creating a private cvrnmunity as ►yell as area residends' desires to prevent additional traffic on residential streets would he negative impacted by this alternative. Gaiwsy Stree# Extension - This alternative vvvuld require extending Galway Street north fro m the exrsting temporary cul-de-sac w%#hin the Ratch#o rd Acres plat d irectly into the Shelley Lake plat and connecting to Road "N," This aptian vrras not presented in the preliminary plat exhibits at the Scoping hearing. As stated abvve, during the scoping hearing Cvunty presentativn and testimany indicated that the primary through cvrrnectivn between the twv plats wvu1d be the Ro#chford DriVe and Cvnkiin Road connectian. Substantial pubfic testirnony revolved around this issue, wath cnmments indicat7ng that no cannection wvuld be desirable to the residents in the Rvtch€ord Acres plat. The effect of this optian is similar tfl the extensio n af'Shamrvck Street discussed ahvve. This additio nal rvad cannection would allow for greater dispersal vf traffic in the neighbvrFaood and less traffic cancentration on Rntchford ❑rive, and may result irr a nnare cuhesive neighbarhovd. Additianal raad connectivns will detract from the concept af creating a private community and w+ll not be consistent with the desires expressed by RotchfDrd Acre Tract residents to preaent additional traffic in their neighbnrhvod. 14e-classifyfng Road "N, °Sharrircrck Street. Galway Street end Gourt "F" es Public RQads - This alternative assumes that the pre►riously discussed through connections are made ta exist+ng ar future public roads to the east via Rnad "N" and ta the south Via SFaamroGk and Galway Streets. This aption aIsa rennaves the f'€JD averlay zone frvm tlne Suburban Residential (SR-1 ) zaraed partion of the project adjacent to the Ftvtchfvrd Acre Tracts.

There is na surface outflow. Accarding to the Recannaissance Data on Lakes in Washinaton - Volume 7, 5helley Lake lies at 2,025 feet in elevativn, has a tu#al surtace area of 37 acres, a maximum depth of 41 feet, and a tatal vvlume of 710 acre-feet (see Figure 5). However conditivns haae changsd since these figures were estimated in 1952 by the I]epsrtment of Game, and the fake has significantlyr decreas+ed in size. The Department of Ecotagy established the ardinary high water elevatian at 2,009, ifeet, 15.9 feet lower than the elevatian preWiQusfy reported by #he Department of Game. At this Ivwer elevatipn, the lake cvnsists of approximately 21 surface area, has a maximum depth of approximate#y 25 feet, and a total vvlurne of apprvximately 231 aCfe-fQ@t. The Iake's vvater level fluctuates seasonaiiy in accordance wi#h precipitation amaunts and the resulting intermittent stream flow. LaPce Fevels were mvni#vred from la#e MarcFr thraugh September during the cvurse of this study. In late March the fake feuel was a few feet helvw tfie ordinary high water elevation. By late May the lake had risen up to this mark, but by rnid June it had fatien bac'k tu below its pre►rious level. Similarly stream flow was high in late May, but by mid June the strearrnbed was tDtally dry. The current property awner reparted that Saltese Creek flows inta Shelley Lake far anly a few wee[rs during the spring of each year. Site visits in late ,June thraugh September indicaied steadily decreasing water IeueEs, estimated up tv approximatety eigFrt feet helow the vrdinary high water elevatian. At tYris decreased level the sur#ace acreage of the lake is apprvxirnatety 15 acres, with a maximum depth of apprnximately 17 feet. Regardless of its surface elevafiarr, the bottom of the lake lies at an apprvximate elevativn ❑f 1,984 feet. The prvject site is underlain by the ,pokane aquifer, which is vne of the mast prgdvctive aquifiers in the United States (uSGS Water-Supply Raper 2265, 7988). As the anly sign ificant source of good-quality water supply in the 5pvkane Valley, it has been designated as a "sole source aquifer" by the US Environmental Protection Agency (EPA). 5helley Lake Oraft E15 25 Fe6ruary 1994 The Spakane aquifer underlies sn area of approximately 135 square miles and varies in saturated thickness from a few feet ta 500 feet or mvre. This uncanfined aquifer consists of sand, graVel, cobbles, and boulders dlepasited during se►►eral catastrophic glacial outbursfi flvvds during the Pleistvicene era knvwn as the Spvkane Flvvds. The aquifer is recharged hy graund water underflvw 'Prom the Rathdrum F'rairi$ aquifer in fdaho, by ground water ftaw and surface water ~seepage fravn small drainage areas alvng the Spokar~e Valley margins, and by percolstion fram precipitatian, the Spvkane and Little Spokane Rivers, septic tank drainfields, and irrigatian waters. The high rate of ground water movement thraugh the highly per Teable aquifer materials has resulted in grvund water quality being little sffected by aVerlying land use activEties. 5everak streams drain areas of uplands adjacent to the ~pokane Val3ey, inckuding the autiet strsams of Liberty. Ne►ivrrian, and Hauser Lakss, ~Ivwever their flvws cease alang the Va[ley margins where the wsters sink into the highly permeable ►ralley flavr raiateria1s. I The majvrity of the project site is underlain by fl[aod depnsits cnnsisting of boulders, cohhles, and graVels, mixed with sand in places, that are mvstly coarse and very poorly sorted. The geology of the bluff area ealst of the lake consists of undivided metarnorphic racks including coarse-grained quariz-feldspar-mica gnei5s and medium- to #ine-grained micaceous and sillimanitic schist (USGS Greenacres Quadrangle Map)., A laysr of Latah Formation cvnsisting of mastly clayey and sandy shale underlies the alludium flavd deposits and metamarphic rocks (USGS Water-5upply Raper 2265). gasalt fIvvvs of the Columbia Rtver Basalt Grvup are possible and an injscted basalt dike is suspected to be located somewhere near, 'Shelley Lake (Lysrla, DOE). Sails v'~ the project site mostly cansist of grav~elly and ve~ gravelly loams, with the bluff area cansist'rng of very rocky and extremely rQCky complexes. - Shelley Lake was prabably farmed during the Sp~lcane Flvads and may be the result o# a plu nge pool (Guliclc, D NR), A plurrge pool cvu ld have fvrmed when water flvv+ued v►►er the metamorphic rocks on the east and igcreasing in velocity scaured ocat a depression on the dQwnstream side. According to Dr, F'sul L. Weis of the L1SGS, the eraded gravel material ►rvas redepvsited in a teardrap-shaped rrtound vr 4ar dvwnstream (south) of Shelley Lake. This giravel bar is an exceptianally weil pre5erved geolvgical feature and is ane of the mI nst remarkahly perfeGt examples of its fvrm known (Weissenborn. USGS). The gravel bar is Ivcated adgacent vn the sauth ta the praject site in Ratchfard Acre Tracts. RotGhfvrd Drive runs dawn the center of the gravel bar. Shelley Lake is mnst likely perched, meaning thalt it prvbably sits on tap v4` the Latah clay fayer (Gulick, []NR), separating Shelley'Lake from direct cvntact wzth the Spukane ' aqu+fer. The lake may be fed by underground springs between this Latah ciay formatian and flnod depvsits. Since Saltese Creek is nat y$ar-rournd, the take would mast likely dry up cvmplstely if it's nat also spr'ing fed (Lyerla, DDE). Water table conto urs #or the S pakane aquifer indicate that beneath the praject site the aquifer is lacated at approximately 1,945 feet iri eleva#ivn, with 400 ta 500 feet of saturated thickness (USGS Water-Supply Paper 2265). In additinn 21 well lags were Shelley Lake Draft fl5 26 ~ FeSruary 1994 reviewed within a two mile area surrounding the prvject site. The aUerage static water level for these wells was 1,947.5 feet in eIeVadion. Wifh the lake batdom elevation appraximated at 1,984 feet, there is apprvximately 39 to 42.5 feet of separatian hetween th+e bottom of She4ley Lake and the top of the Spqkane aquifer. Shelley Lake is #ed by Saltese Creek which serves to drain a watershed area of appraximately 22 square miles lying south and east of the lake. Nlvst of the tributaries of Sa1tese and Quinnamose Creeks fiaw through rvfling agricultural land with scattered residences an large parcels. 7hese tvua creeks c❑nverge at whai vvas _ once the southern extensivn of Salnese Lake. This 1.500 acre lake was drained priar to 1910 and is nnw called Saltese Flats. Accvrding tv Lakes of Washinaton, tWater Supply Bulletin Na. 14; 9964y, abvut 50 acres of intermittent marsh remains at the narth end of the kaks bed. Three drainage canals run narthwest tv southeast thrvugh SaItese Fiats and water #law is cvntrvlled 'hy irrigativn gates. Qrainage canals run thraugh an appraximately 50 acre area that is mined fvr peat moss. Saltese Creek flows from the north end of the drainage canals narthwest to SheIlsy Lake. The water quality of Shelley Lake has nvt been analyzed except for a study done by the Qepartment of Ecology in 7974. Results of that study are docurnented in Reconnaissance Qata an Lakes in Washinaton - Volume 7 and are prawided in Tahle 1, As preuiously discussed, Shelley Lake has significantly decreased in size since 1952 when the physical parameters of t'he lake were estimated and as reflected in Table 7. Howeaer the water quality data prgvided can secue as a baseline #Qr future water quality testing. The data provided from the 1974 study indicates fairly high Ievels of tutal nitrflg en and tvtal phvsphorus, Iow ievels of dissolved vxygen, and limited Vasibility. Little nr nvne of the surface and shareline is cadered by emersed planfs, 7`he Iaw Value fvr shvreiine cflnfiguration suggests a lack of shallvw water and prntected bays which lim9#s the lake's capacity for plant grawth. Feca1 cvliform calonies are Iow. The high levels of tv#aI nitrogen and total phospharus can be attributed ta the #eed Iot that was then Ivcated vn the nardh side of the lake and ir+cvming ireigativn water carataining fertilizers and pesticides. There is no cvrrent information available on the water quality of 5heiley Lake. Havvever visual QaserVations suhstantiate the lack of macrvphytes (roated andf Ioating aquatic plants) and limited water ►risibility. Feed lat use stvpped in the mid 1970's, _ hawever irrigation run-off from agricultural uses in the Saltese Flats area cantinues. During May and June the lake contairaed large amourats of organic particulate matter and was a tea-like brvwn in calar.

The Water Quality Standa►ds far 5urface Waters regulativns (C hapter 173-201 A WAC) establish state standards fvr water qua#i#y and implernent the 1Nater Pvllution Contrvl Act. These regulations mandate that activities which cantribute to pvllutivn be _ conducted using best management practices ta prevent viofativn of water quatity criteria, in accvrdanCe with Department of Ecvlvgy ciirectiVes. Lake ecosystems are complex and highfy intercnnnected. In-lake plant productian usually fnccns the arganic matter base of the lake's faod web, and mast lakes require a reliable level of algal and macrgphyte production ta rnaintain praducti►►e food webs (The Lake and ReservoEr Restaration Guidance Manual, 1990). Healthy lakes hade a fvad web that inVVlves the flvw a1` energy among the lake arganisms and the recycting of nutrients. The process of phvtasynthesis hy aquatic ,plants praduces flxygen, - which is the primary saurce of dissolVed vxygen in water. Oxygen is required to sustain fish pvpulativns and is required tv cvmpletely hreak dvwn nrganic matter. During the respiratian process, the bacteria that decvmposes arganic matter cansumes - axygen and releases carban divxide, water, a nd energy. When incvming water is high ~ in nrganic matter, the bacteria can consume the lake's dissolved axygen suRply more - qufckly #han i# can be replenished. This can lead to fish kills, edors, and nvxivus - cvnditiqns, and is most 7ikely a majvr cantributing factor ta the water quality limitatians of Shelley Lake. , The prvicess of photasynthesss requires 3ight, sv plan# praduction is restricted ta the upper partion of the water cQlumn. Submergent plants will graw profusely only where underwater illuminatian is sufficient. 5teep-sidec# Iakes support a much smaller - development of macraphytes because #he bottvm sedrrnents are too dark ar tva deep. In additivn, when aottom sediments are highly inorganie (sand], rriacraphyte growth may be poor because it is diff icult for ravts ta ohtain nutrients in this sediment type. Alsn wide seasonal vvater level fiuctuativns can prevent the estabtishment a# rooted aquatic plants who cannvt toferate the dry conditians created when the water leve! draps. Shellsy Lake's fairly steep sidss, s4il types, limited Wisibility, and high degree - ; Shelley Lake araft E1S 29 February 1994 of water level fluctuations have a11 cQntributed t) its lack n1` aquatic vegetativn. b. 5ignificant Impacts The current water quality of Shelley Lake has been degraded by up-stream and possibly vra-site agricultural practices. Safl additiVes such as fertilizers and pesticides harre artificially increased nitragen and phnsphorus IeVels within the lak+e. Peat mining operations in the Saltese Flats have added suhstantially to organic particulate matter infiaw. Decompasitian of this arganic matter has ~depleted dissolved oxygen supplies. ~ Without axygen the decompvsitivn prvicess is 'only partially cvrnpleted, creating anaerabic canditions which have led ta fish kills, reduced Visibifity, and vdors. fihs additian of imperviaus surfaces ta the curren#iy undevelvped site will change the - directivn and speed of mvVement of an-site suirface watere Alsv if not managed _ prvperly the removal of vegetatian and disruptian 6f soii during canstructian cauld add , tv the amaunt of cont~aminates and sediment reaching the lake. ' C. Mitigating Measures , , The prnQosed project will decrease the movement of surface water across the site and reduce the amvunt of run-aff reaching Shelley L6ke. This will he achieved through design parameters which establish setbacks that maximize the distance of stvrm water travel frvm develaped portivns of the site to Shelley Lake and the SaItese Greek streambed. Also ►►egetative huffers and retention ponds will slaw vr contain excessi►►e run-aff and a storm water management plan wiln be designed to divert stvrrn water away fram ar aroUnd critical features such as steep slopes, unstable svils, vr Vafued habitat areas. See sectsan 1.2 fvr mvre discussion of impacts and mitigatians reiating tv soils and run-aff. The propvsed project will limit a pcatential water quality hazard_ by prohibiting ar restr3cting animal keeping. Large animal-keeping rrvi!{ not be allawed within the prnposed PUD. The prnposed project intends tn pratect sensiti►►e areas from human and residentia! - development encroachmen# by proViding a5Q fovt buffer around the shnreline of Sheiley Lake and Saftese Creek, 5hareline and wetiand areas will be ,pratected and restricted fram any future development. Efforts to mitigate currently existing degradation of Shelley Lake's water quality are alsv possible as part of this project. Rrafessivna'I water quality sarnpling and testing would need #a be completed prior tD initiating pvtentia! lake management techniqves. Future ►rvater qualitylquantity impro►►ement progrems would be at the directivn of the _ Shelley Lake Hvmevwner's Assaciatian. The Departrnent of Ecology was natified in August 1993 regarding the lake's existing _ water quality and will assist in analyzing potential upstream polltatian SDUCCBS. Shelley Lake Draft EIS 30 February 1994 Application oi best management practices to remvve c+ontaminates from #he - streambed at any identified source upstrearn frvm the projeci site ►will be at the direction af Ecalogy staff. If prnpased by the homeorrvner's assaciativn, asedirnent - filtration sys#em couId aIso be established in Saltese Creek where it empties intv Sheiley Lake. This would rema►►e the arganic particulate matter from the water befare _ it reaches the lake. These efforts wauld reduce the depletion af dissvlved oxygen and EmpraVe water visibility and clarity, irnprvving aaluable aquatic plant productivn, - reducing odocs, and improving cvnditians far Viable #isheries prapulativns. Anvther rnanagement technique typically rased to increase the dissolwed vxygen Guntent of lakes is aeration Qr artificial circufativn. This technique elirninates thermal stratification thrvugh the injectian vf compressed air frvm a pipe or diffuser at the lake's bvttvm. Nnxious slgal bivvms are aIso cantralled by incr$asing dissvlved - oxygen levels in the water column. Maintaining a stahle water level thrvughout the year would create an enVironment for ther establisharnent vf emergent and submergent aquatic plants. Increased plant productivity would alsa rracrease fevels of dsssafved oxygen thrflugh the process af phatvsyntFresis. Maintaining adequate and stable water fevels evuld possibly Qccur by increasing +nflovv from Saltese +Creek during #he dry summer mvnths ❑r pumping addi#ivnal water inta the lake. Increasing the inflow to Shelfey Laice fram 5altese Greek would require abtaining a surface water right frorn the Departmen# of Ecalogy. Application could be made fvr recreationa6, wildlife hsbitat, vr aesthetic use and would take appraximately one and ❑ne-half years to cvmpfete. During that time Ecvlagy would deterrnine if: ~ the request is detrimental to existing water rights ~ addit+onal surface water Fs available far use, and ■granting the request wauld be in the public interest. Due to the existing agricultural use and limited supply during the dry summer months when additional wster woufd be needed in Shelley Lake, there prvhably is nat any excess water ava'rlable in the Saitese Creek drainage (Farmer, p[]E). 'W'ater could be imported into the lake by pumping fram the existing ❑n-site well. The well lag indicates that this well was constructed in 1956 and has a yiefd of 700 gallons per minute (gpm). Property owners haVe retained a water right far irrigatian since the time o# wefl deUelapment. Hawever, same welf water needs #a be used this seasvn in ard'er to maintain the current water right. If water is not used within a fi►►e year periad, the water right re►►erts back to the State. An application far a changs in use to recreatian would need to be approved in arder to pump water frvm the well intv the lake. The current water right onty applies throughvut the irrigation season, whie9h wvu#d correspvnd to the seasonal need far additional water in Shelley Lake. R well yielding 700 gprn could sup ply approximatefy 1,1 29 acce-feet v# water per year Shelley Lake Ureft E15 31 February 1994 ;I - if pumped continuously #hrvughout the entire year. As preuiously discussed, at the fake's ardinary high water eleVativn it has a surfaGe area of 21 acres and a volume of approxEmately 231 acre-feet. Assuming an eEgh# foot d rop ira the water ievel from high water irr early June to the Iowest es#imate+d level in late summer, results in the Ivss of approximately 168 acre-feet of water. Theref;ore it can be estimated that the on- srte wel1 wauld need to yield apprnximately 208 gpm pumping vver six manths vf the year to replace vuater Ivst to infiltratian and eaap❑,ration. If additional wa#er is required far anly four rrlvnths, then the welf would need!'tv pump at a rate of appraximately 312 gpm. These pump rates are estimstes only and do not take into accaunt varying evaporaxivn rates due to seasvnal infiuences and hydraufic head pressure changes due ~ to fluctuating water volumes. ;i Vlli#hdeawal of graund water cnuld patentially impact ground water tsveis, nowever the pumping rates that may tae required by this project are substantially less than the 700 gpm rate that was previvusly permitted fvr irrigati;orr use. Therefvre application af this - management technique wvuld have less of an irnpact on ground v+rater supply leuels , than forcmerly permitted. In addition much of the~water supplied, other than that fost to evaparatian, wauld infiltrate and recharge graund water supplies. , 1.2 Run-DfflAhsarption I a. Atfected Enaironment .I ; ;j FRun-offlabsarption rates are influenced by bvth tvpvgraphy and sosl type. The topagraphy Qfi the praject site Varies from gent'ly rolling at the svutherramost and northernmvst portions to steep s1opes along th'e lake frantage and along the east baundary. the project site's mast prvminent featvre is Shelley Lake which is bardered hy the propased plat on all but the east side. 5helley Lake acts as a natural sump area for seasanal flows fro m Saltese Creek, which drains a basin to the eas# and snuth of appraximatefy 22 square cniles. 5ince Shelley Lake has nv natural vuttet, al1 storm , water whieh enters the lake is dispvsed af thrnugh percvlatian and evapnration. _ The 724 acre prnject site is located within the Garrisan-Marble-Springdale soil association according to the Gerreral SQil Map af Spokane Cvunty, Washingtan (U5 [3epartment of Agriculture Sail ConserVatinn 5eniice, i I SurVey of Snmkane County, ►dVashjngtnn, 1968). This association is made up of somewhat excessi►►ely draFned and excessively drair~ed sandy and gra►►elly soiis formed in glacial outw~sh. I The project site cantains five distinct svil mapping uniCs tGgA, GgE3, GmB, StC, and SuEy within the Garrison arad Spokane series an~ an abandoned gravel pit area. As shQwn ❑n Figvre 6, the majarity flf the site, Gvnsists af Garrisvn series soils representsd by Garrison gravelly Ioams (GgA and Ggs) and Garrisan aery graaelly laam (GmB). The Garrison series is nnade up of samev"uhat excessiUely drained, grauelly or siony sails that tvrmed under grass in glacial ouitwash mixed in the upper part wtth Volcanic ash. ~ Shelley Leke Draft E!S 32 February 1994 The 5pvkane series is represented by Spakane very rvcky cvmplex JStG} and Spakane extrernely rocky cvmplex (SuE). The 5pvkane series cansists of well-drained soils that have a sandy substra#um underlain by bedrack at a depth of 20 to 60 inches. These sails formed in weathered granite or thin deposits of glacial till aVerlying granite, urrder conifers and grass. These soils are Ivcated along and ta the east of the eastern shore of Sheiley Lake. A small vutcrop of Spokane Very rQCky camplex is iacated in the , sauthern pflrtivn di the paojecd site. Figure 6 shaws a gravel pit area lacated along the Lake's nvrthern shvreline within the project site. The presence of a gravel pit at this ivcatEVn is nvt evidenced kry ❑n-site - obseruativns. Asecvnd gravel pit is lacated adjacent ta the northeastern site - baundary. Other than the Saltese Greek watershed, the prapvsed praject site does nvt contain any majvr drainage coursss. Run-aff within the site is presently disposed of by natural means. Snvw melt and stvrm riva#er Is genezally absorbed by the permeable soils - found within the area when the ground is nvt feozen. b. Significant Impacts The praposed project consists of the develapment of 459 residentiaN units, iracluding 195 attached residences, GS manu#actured hames, and 196 single-famify residences araund Shelley Lake. Roads will be eorrstructed tv access the multi-family area and individuat fots. The characteristics of the svils in tFre area factvr intv the carrying capacity of the sita ta determine its suitability far the consttuctivn of residences arrd roads. Table 2 outlines the characteristics of the sail types fvund on-site. The add¢tion of a built enrrironment has the pntential ta intensify the amount of run-aff and sediment taading reaching Saltese Creek and Shelley Lake. The additivn of impervivus surfaces to the site thraugh the constructian of hames, drirreways, and roads willresult in the inability ❑f water to be ahsorbed ira the pre►riously undeaelvped areas. The impervivus surfaces wi91 create an enviranment with a large valume of run- aff that wili need to be diverted and managed arr-site in a stvrm water system. Any accumrulated run-otf, if directed vver a steep sloping area, will accelerate and inCreasQ its patential to carry sediments and ather particles. Alnng with the increased risk of erasivn, there cvuld be the passibility of incising ths existing drarnageways by the increasetS volume of discharge they must accammvdate. All of these factars need ta be taken into consideratinn in engineeeing a stvrm water management plan fvr the deVelopmen#. DeVelapmsnt of the prvject site will alter the existing run-off characteristics. Urban pollutants will be picked up and travel with the excs5s run-off. Llsing responsible mitigation measures, the excess run-off shvuld be able ta be rrfanaged in a way that will nvt significantly impact the surrounding errviranment. s►,erley Laxe Dreft Ers 33 February 1994 T►4BLE 2 Svils Characteristics , . : 4 ' F , .

IVIiti9ating Measures The prvposed project site dves not contain any majvr drainage cvurses besides the Saitese Cresk watershed. The ten-year design starm run-vff from lacalized an-site ba5irrs will be dispased of using "208" grass percolation areas and drywefls in accardance with tFie Spakane Cvunty Guidefines fnr Starm Water Manaaerrkent.

The variable tapography of the si#e will likefy resuft in avaristy of inethods to capture and dispose of run-vff fram the raadway Fmpervious svrfaces in vrder to provide "208" swale areas which are acceptable fram the standpvints of constructability, maintenance, and aesthetics. Sail and surface disrupt3on carr be ~minimized by sensitiVe +enVironrrrental site design and planning. This is especially true for develvpments a1vng sharelines vr an stesp slopes. The project site has been designed sv that #he majarity of cvnstructi+vn activities are located fln relat3vely flat slcrpes. Appropriate setbacks and retentivn of ; natural vegetativn will be maintained where pvssible. Ig,n ecasion contrvl plan wili be required by the County Engineers priar ta beginning carrstructian.

Affected Environment The Spokane region typically experiences both ;spring snowmelt and wEnter flovds. Spring flovds are caused by snvwmelt run-aff fr'om higher efevatian watersFaeds and are influenced by the amaunt of snawpack, terr~peratures, and the timing of heaay rains during the critical snowmelting period. Winter flaods are the result vf warm temperatures and heavy cainfall, frozen sQil co~nditions, and snnwmelts praducing short-duration, intens$ v~an-vff. 5helley Lake and the SaItese Creek drainage west af the Steen Road bridge are Incated within the "Un-n umbered ►A Zone" flood zone area accvrd ing to the Federal Emergency Management Agency (FEMA) map attached as Figure 7. This designatimn rneans that a detaiied study has nvt beerr cvmpfeted for the;Jake tfl establish the 7 d0-year flood eleVativn. The 7 am-year flood plain eleVation is defined as the wa#er surface eleaativn that wvuld have a statistical probability of ane ,percent of occurrrng in any given year. A 1 00-year flood plain elevation of 2027 (U5G5 Datum) has been esdablished at the Steen Ftcrad bridge, which is located u,pstream and ta the east ofi She[ley Lake. Praperty ov►►ners adjacent to tFoe project site have reported prablems with flovding in the area in the pasts in addition, Spolcane Caunty Engineers files show that during a 1948 chinaak eVent, Shelley Lake over#IQwed and was observed ffowing across Sullivan and Cvnklin Rvads. Hvwever a drainage channeA leading t+a the Spvkane Countyl5helley Lake Gravel Pit, nvnhsast ❑fi the prflject site, current1y acts as an emecgency oVerflav+u fvr 5altese Greek and 5helley Lake. This channel appears dv be nnostly af natural arigin, however a newspaper article indicates tFaat it may be at least partially man-made. This unreferenced newspaper article is quoted as foflows: "Rerrrembering... Back in Rllay, 1948 a quick thinking Coun#y Commissianer and a bulldazer vperatvr solved a big f#avding prvblem. liVater fram the drained Saftese La'ke bed surged several feet deep across three, Caunty roads and several Spvkane V,alley farms.

A smaller grassland area is located along the western shorelEne of the southern extens'ran of the iake, and extends up a gentle slope ta #he cultivated field area. Granivares (seed eating animals) and grazing herbivores such as radents and +nsects are typically suppurted by this type of habitat. Grassland areas may also ae used far hunting by predatvrs such as hawks and cvyvte. The biuff directly east of the lake su,pparts a punderosa pine Vegetative community that extends narth ta a gravel pit located n+ortheakst of the project site and south tn the Saltese Creek drainags. 5teep slvpes and rac,ky areas alsv suppprt natiVe hunch grasses, perennial farbes, and small shrubs. 7his habitat suppvrts a variety ❑f birds, small mammals, and occasivnally deer by prouiding ca►►er, breeding, and fieeding areas. An area of mastly nativB 5hrub5 is Ivcated sauth and west of the sautheasterly extension of the laice. 7his area consists of nlative shrubs, perennial forhes, and grasses including buckwheat, bla nketflowers, lupines, ya►row, and serviceherry. This habitat provides co►rer, breeding, and feQding areas fvr smali rodents, insects, and b'rrds. Three areas of riparian vegetatian are Ivcated near the lake's eastern and svuthern edges. A smsll wetland area extends frvm t lakeshore r~vrtheasterly into the blu#flponderasa pine uegetative community. Na h~e ~ isible e►►idence of surface water has been noted in this area, hawever several pvpulus species including willow and IQmbardi are lacated here and sautherly along -Che lake's shoreline. This area alsa contains shrubs including hawthvrne and wild rvse. A second area of riparian populus species is Iocated along the eastern lake edge, just north of the stream entrance. The third area of riparian vegetati❑n is Iocated at the tip of the lake's southern extension, west of the stream entrance. The relatively flat slvpe and fine grain soil canditivns faund here suppart a variety of sedges, altho6gh they are fev►► in number. The , ripariarrlwe#land vegetative areas suppvrt nest Ing and feeding opportunities far a _ variety of birds, small mammals, and aquatic insects. Hawever, these areas are fairly iimited in siae and species diversity. The Washington 5tate aepartment of Naturaf Resources was cvntacted regarding infarmativn on significant natural features in the praject ar@a. A ssarch of their data base did nat reveal any records of state endangered, threatenedr Qr sensitive plants ❑r high quality natiae plant communities ar~d w~tlands. 7he follvwing speciss of hirds, animals, and fish vr eVidence of their presence were observed on-site during the course of this study: Ring-neck and cinnamon t+eal ducks, great hlue heran, red tail hawk, pheasant, quail, fryca#Ghers, killdeer, swallvws, robins, flickers, kestrels, wren, chickadess, great harned vwl, fiehd mice, vales, squirreEs, marrnats, turtles, 5kU11k5, large mouth bass, and perch. Because of poar water quality and extrerne water Ieve1 fluctuatinns, 5helley Lake does Shelley Leke Draft EIS 42 j February 1994 nat suppart a significarrt fish popuiateon.

The Washingto n State ❑epartme nt of Wi9dlife was cvntacted regarding in formation on significant natural features, m€gration routes, and fish populations assaciated with She6ley La'ke and the immediate vicinity. A revievv af the State's data base did nvt result in the identificatian of any species of cmncern within aone-mife radius flf the p roject site. Their recards of fisheries re sau rces ❑n ly irrdicated th e presence af yellow perch within Shelley Lake. h. Significant Impaets The areas of the project site prvpvsed fnr the development ❑f hames, streets, and assvciated utiffties are [acated where there are relatiVe1y flat sfopes which cansES# mainly of cultiuated fiefds. A soft pedestrian traii will encircle the lake abaVe the ordinary higlh water mark, and somewhat disrupt the grass and shrub natural habitat areas. Develapment of these areas will require the remoVal of knapweed and some native plant species and wicC likely encraaeh upon some vf the habitat areas used by wiedlife. The Ivss of wildlifie hahitat resulting frvm evnstructian and deWelapment of the site wilf be an unavoidable @rnpact fvr same of the existing wildfife tha# is unable ta successfully relvcate. The corrstructian of residences and rQadways will cample#ely sliminate all agricu6tural practices on-site. This vvill necessitate removal af the associated fringe and stubble areas bordering the fields which provide cQVer, breeding, and feeding for avariety a# birds, insects, and small rodents. C❑nstruc#ion of the soft pedestrian traiE thrQUgh grass and shrub fiabitat areas will also im,pact these same types of wildlife. Site design has allawed #or 37.9 acres of o,pen space (including 21 acres vf surface water) t❑ be Jeft undeveloped ta accvmmodate the existing wefd9ife. As the site develvps over time, wildfife will be fmrced ta mqVe to open space areas vr take afterraate paths in areas where existing paths and habitat will be remoued. Wildlife wifl he exposed to a greater number vf pevpae, their associa#ed activQties, and resul#a nt noises due ta the influx o# residents tv the area. 5vme species may be Ivst 5he!!ey Leke Qraft FIS 43 February 1994 i if they are extremely sensitive and cannat adapt tn the changed environment, even though adequate habitat is prvvided. Hawever, the open space prvvaded by site design will accammadate a farge partion o# the exustirrg wil'dlife. c. 1Vlitigating Illleasures The propased develapment project will designate 37.9 acres as permanent apen space, which oncludes tFae lake (cvnsisting df 21 acres) and svrraunding shoreline and riparian and wetland areas. This will aIlnw far the preserVation and enhancement of these sensitiue areas and the surrounding enVirans by cvrrtrolfing human con#aGt and use. The profect would cantrvl and restrict large aniirral-keeping, herbicidelpestacides, and fertilizer use in areas where run-aff could impact the lake and vvetlands. Mvst nf the undesirable knapweed along the lake's nnrth, Iwest, and east sharefines wili be eliminated. Wetland and shareline areas will be 'enhanced by plantings of natiWe grasses and 5hrubs ❑f high vaiue to wildlife. The proposed development includes a svft pedest'rian traia on the slape around the perimeter of the Iake. The trail will be located on a slape within a 50-favt huffer area establishsd between the Iake's ordinary nigh watellr e1e►ration (as established by the Department af Ecvlogy) and the individual prmperty baundaries near the top af the sevpe. A broadcast spray (Rodea) wifl be vsed tv cantral kraapweed in the areas r►vhere it is mvst preda'Pent. It may take twv to three years with several app[ications per year ta bring the knapweed Gnder cvntroG, This spray wil9 alsa eliminate the small amount o# grasses and forbes mixed in with the heavy areas of knapweed. in areas of mos#ly native shrubs an d forbes with lesser amounts af kna'„pweed, the knapweed wiI l be spot sprayed using Radeo in arder to retain the existFngl faigh Value aegetatian.

The existing SR-1 zone with a PUD overlay is;, carrsistent with the 5uaurban(+) ~ I , Shelley Lake Drafi E15 56 February 1994 categvry of the Cnunty's Camprehensive Plan. A detailed definitian of the Suburbani + 1 categary as faund in the County's Comprehensive Plaro follQws: H3ETAILED aE'FI'N1TION DF SUBURBAN(+ ) A. Density Charscteristics. All residentiati net densities shaII ran$e from ane acre per dwe1ling unit ta 5 acres per dwelling unit. L3ne acre per dwelling is the minimum to ma;ntaira the large-animal-keeping lifestyle in the Suburbani } 1 area through implementatian of zoning. , B. Characteristic Features: The predominant use in the Suburban(+)categvey will be single-family units on _ lots which ha►►e cansiderable space far garden'sng, boardeng a limited number r of far+ge anima1s or perhaps simply natural vpen space. Few cammercial uses will be found in tMe Suburban(+) areas.

The aesthetic setting should be predaminantly single-family residentwal ' Structutes on large lats. Houses shauld be well spaced and separated hy 4arge _Iawns, gardens, planted trees or native Vegetatidn. Most hvrnes will enjvy a IimEted view of open space in either agricultural use or cratural cvnditivns. Few buildings will be multi-stvey beyond twv stvey. Home prnfessians ar hame industries wauld be allovved if the activity maintains trie c'haracter and assthetics of a Suburban(+) residential area. C. Public Facilitiss and Services: Suburban(+) areas shauld have public water systems fon-site sewage dispasal systerns (or public sewers, sanitary and stvrm, when such facilities exist nearby vr when required by public health issues), paved and curbed stceets, police and fire prntectiora, utitities, and pastal service. Additionally, refuse catlectivn and removal, medical facilities, public transit, and Iibraries a11 will he availahle but _ aften at a iawer level of service than irr the Urban areas.

Nancampatible Uses: - The Suburban( + ) category is basically residential, and therefore most industriaC, majvr commercial and rnining acthVities are incompatible within t'his categary. Multi-#amily uses are incvmpatible within the 5uburbara(+) areas. Light ' Irrdustrial uses would not be compatible writhin Suhurban(+ ) residential area5. Qther small or independerat businesses woufd not be fvund in Suburban(+) residential areas.

Ths survey for cultural resources was completed lat the prvject site on July 23, 7993. Surface and su bsurface examinations were accamplished hy a six-mem'be r field crew. The surVey area was divided inta four zanes and field svrveyors were deployed acrass eacha zone walking regular systematic transects 1~0 to 15 meters apart. Widths af the transects ►rarried to accommodate 1andform feat" ures snd grvund caVer. Numervus shavel probes (116) were excauated th raughout the site up to depths of approxhronate ly 57 centimeters helow grflund surface. Most af the site offered high sur#ace visibility due to the large extent of pIawed fields and lack pf heavy ground cover. Findings Qf the field survey included a possible basalt #lake, a possible end hattered cobble, and an unlikely piece vf pvssible fire cracked rock. No significant cultural resvurces were fvund on ths project site. Shelley Lake Oraft EIS 64 i aFebruery 1994 ~ Current prnperty awners stated that preViaus Qccupants indicated the presence of Northwest American '1ndians in clase proximity to Shelley Lake. The Rice`s were told that members af ►aarious local tribes, incl+uding women and children, wauld meet somewhere nearby in order to settle their diiferences.

It is recognized that after fiull build out, this intersectimn wif# be , vperating with levels of ser►rice in the LOS ❑IE range. Par~ ~f the decreased level of service at this antersectinn has been in respanse to the pvor levels of service and fimited capacity available at the Sullivan Road and 4th Avenue intersectivn. Due to the realignment of the 4th and Cvnklin intersectinn, traffic will be encouraged tv use the 5prague and Conklin intersectipn. This will be facilitated by the impravement of Canklin Raad to a 40-favt sectivn with curbs and sidewalks vn bath sides fram the intersect'rvn with 4th Avenue north ta Sprague Aaenue. At this time and with the future IeUe4 of ser►vice at an LOS of EIF, the mitigetian at this intersectian will inuol►►e > the installation of a traffic signal system. Additionaffy, rewisions to the County Arterial Road Plan will be pursued tv include an intersection with GQnklin Road and the prvpased 5auth Valley Arterial, requiring a he'aring befpre the Bnard of Cvunty Cvmmissis~ners. If the 5auth Valley Arterial is cc~~nstructed sast of Sullivan Rvad and revisian of #he Cvunty Arterial Rvad PEan is net obtained ta allaw !his intersec#iion, then potential rnitigation cvuld include forimation of a Road lmprovement District (RIQ) for cvnstructian of a bridge ar underpass ta bypass the Svuth Ualley Arterial and allvw thrnugh acc8ss to Sprague AVenue.

ANthaugh significant in the fact -that the overall reduction is three IeVels of service fram an L05 of A tv an LOS of D, ihis reductaan in LOS is still abave the minimurn acceptable LO5 as ic#entified by Spokane CAUnty. the secvnd intersectivn to experience a reduction in LOS is the Sulliaan Road and Sprague Avenue intersectivn. This intersection reduces frvm an LQS of a with an a►rerage delay of 36.0 secvnds to an LQS of [31E with an average delay of 41.6 sQcands, Althavgh the'LOS D lewef is exceeded, an increase of 5.6 secands of total delay's arbitrary due ta the somewhat subjective nature of signalized intersection level of service calculations. Usually the rule of thumb would state t'hat with mDre aggressive signal tQming, incvepvrating shorter cycle len+gths, and incorporating rnare right turn Qn red ar left turn permittedlpratected phas4ng, a#en tv 25 percent reduCtion in delay can he achieved. In order to maintain cvntinuity between Ievel of service calculativns far review, these timing reVisians °were nvt incorparated. Therefvre, an average defay change from 36 ta 41.6 secands cflu'Id he cflnsidered to be uery little change, if arry at all. Additianally, the primary reascan for the increase in L05 is due ta the overafl increase in xraffic ►►vlumes at this inters$ctimn and the reduction in green #ime fvr the eastbound and westbound directivns given the larger thrvugh vvlunnes alang Sullivan AVenue. Therefore, if there were mare through lanes availahle for thrvugh traffic prvgression or northbound left turns, the OlrBi'a1l IntetSeCtlfln IBVel of 5eiyiCe CQUId b@ maIn3ait1Bd within the acceptable limits of na less than an LOS of D. Althvugh the change 6rom an LQS of D(3 6 .0 seconds) to a r~ LO S of E(41.f secnnds) carries the intersectivn thraugh the L05 of DlE threshvld, several timing reVisions cauld be incarpnrated tv minimize ar negate the Ernpacts. The real rneasure of this signalized iraterssction's capakrilities tv handle the added traff ic Vvlumes is that the vlc rati4 mmVes from a backgraund vlc ratio of 0.78 to a vIc ratia of 0.89 vvith the 5hefley Laka flraft EJ5 78 February 1994 alternative. Therefare, this intersectian maintaiins adequate capacity to handle the ' vvfumes generated by this proposed project as well as ihe backgrauna growChi but the signal timing and existing lane configuration5 da ~nat allaw the intersection tv vperate at it's maximum paterttial. I 'During the PM peak haur this project will reduce the Suf!'rvan and Sprague and the Sprague and Conklin intersect+ons helrrw the leveis 8f servace from the background grawth in traffic. I As witFr the earlier discussions, the leWels of serviee reductions on Sprague AVenue sre nvt reductivns on Sprague Arrenue, rather they are the result of additiQnal tFrrough vvlumes on Sprague Avenue and this through traffic's impacf vn the intersecting side s#reets. 7he impact tfl the intersecting side streets is usually in e!#her the north4vund or svuthbound vnsignalized left turn. As indicated fvr Phase 1cvmpletivn, the irecrease in bath thraugh traffic ❑n Sprague and an irrcrease of 16 left turns reduced the reserve capaci#y by 150 VeY+icf+es. The same is Lrue for Pharse 2 completinn, where the increase in nvrthbaund left turns is tram a pre-deVeloped dvlume of fovr to abuild out volume of 68 left turns at the SpraguelCvnklin intersection. It shauld bs nQted that this volume is approximately half that of the left turns in ihs AM peak hour. However, the higher eastbound commuting volumes on Sprague and the confiict that they present forces this intersectian to an LGS of F, with a reserve capacity of -35. As noted earfier, this is due tv the increase of 64 additEanal nmrthbound ta westhound Ieft turns frvrn Cvnklin anto 5prague. It shauld b+e nnted that the intersection reserve capacity is being reduced by faur times the number of added left turns. This type of capacity reduGtiorr is indicative of increased ihroug h traffic Vvlumes on the intersecting street, in th3s case SpragUe aVenue. ; At tfie SuIlivan Raad and Sprague Avenue intersection, the reductian in level of secvice created is two fvld. First, the increase in through volumes due tQ considerable aackgraund growth, cambined with an increase in left tum valumes #or access to the prvpased Fred Meyer facility, have pushed this intersectivn beyvnd it's capacity tv serve the expected grov►rth. By the year 2004, with a backgrvund Ievel of serv6ce at an LOS of E I90.2 secandsl, the addtitional delay and level of servtce reductivn to an LQS of F(1 17.7 seconds) is the result of the souibbound ta eastbound Ief# turn being beyond capa+city with nv additivnal green time' aVaitable ta imprvVe this lerrel of service. In the event that the Cnunty were to cnnstruct dual lefts at this intersectivn as part of the Sullivan Road imprvvement project, ~ILOS at this intersectivn will increase t+a an LQS of E with an aVerage delay of 55 seconds. b,2 aedelopment Under Existing Znning AfternlatiVe A5 with the Propvsed Acti❑n aIternati►►e, trip generatian estimates were prepared for the rnaximum patential for this alternative. Based upon the existing zaning cade fnr Spvkane CQUnty, appraximately 225 single-family units cvuld be proposed within the Shelley Lake prajeCt side. 5helley leke Draft EIS 79 February 1994 i This alternative will generate varivus volumes of traffrc during construction of the several phases of derrelvpment. At Phase 1 cam,pletion, which includes 5$ single- family residential homes, the project site wifl generate approxEmately 43 AM peak hvur and 57 PM peak haur trips. The anticipated tvtal number of vehicles which will be generated throughvu# the day would be 570 vehicles per day (vpd). Of dhe 43 AM peak hovr trips, 91 tri,ps will be entering the site, while 32 will be exiting. Qf the 57 PM peak hQUr trips, 37 trips will be entering ths site, while 20 will be exiting. At fvll huild vut (2004), this alternatide vval4 generate ap,proximately 7 66 AM Pea k hau r trips and 228 PM peak hvur trips. The anticipatsd total number of dai1y trips which wili access #his site is expected to be appraxima#ely 2,280 vpd. Of the total 166 AM peak hour trips, 44 trips w'slf be entering the site, while 122 will be exiting during the AIVI peak hnur. CDf the 228 PM peak hour trips 148 will be entering the si#e, while 80 will be exiting. At Phase 1 campletion arrd iull auild out {20441, during both the AM and P1VI peak hours this alternative will only af#ect the reserde ~capacity of the 5ulliUan Road arad 4th Avenue intersection. It will nvt degrade the leael of seryice beyond the background L0S for aray of the identified intersectians, including the Suliivan and 4th inte rsectinn. Based upvn the analysis psrfarmed, no d;rect specific impact which would degrade the Phase I - 1995 background level of service o# the surrmundFng street system can be detQrrnined. The anly significant change cvncsrns the degree of irnpact and not the level of service. The RM peak hour reserue capacity of the Sullivan snd 4th intersection decreases #rom an L(]S of F(-21) to an LOS a# F (-143). This signifies that d ue tn increases of thrau g h traffic vvlumes alQng Sullivan Raad, any increase in traffic an the adjacent side streets vvill naticeably reduce the aVaila'ble gaps ta a greater degree ihan the specific number ni cars added. An example ❑f this was discussed fiar the Prflposed Actinn alternatiVe, where 64 left turns were introduced and the reserVe capacity was reduced by a4:1 ratia. The impacts at full build vut (2404) are similar ta thase described abvve fvr Phase 1, only the degree of se►►erity is complicated by develoqmient fiurther south of 4th AVenue, and nvt necessarily by the developmerrts alvng 4th AVenue. Hvwever, the turning vvlumes anto 4th fram Sullivan are significant and wmuld force this intersection tv not anly meet seVeral waTrants for signalization by the year 2004, but would aIso resurt in significant intersectlon impravemen#s such as left turn lanes and intersectiorr signalizativn. 6.3 Nn-Actiorn Altarnative Fvr this project alternati►►e, there will be nv additional tri,ps generated than currently are generated by the existing project site.

It is expected that ali vehicles assaciated wRth the project site will be thrvugh vehicles at this intersectian. Ira the event that Spvkane Cvunty were to revtse this intersection by praviding additionati thraugh fanes, it would be recammended that this project participate tv the percent IeVe1 of respansibility associated with the uolume ai` trips.

Piat cvnfaguratiun tor this alternative incltades extending Ratchford Drive north straight through to 4th•►Avenue. The analysis provided split the traffic feaving the project site, based upon traael time and speed, and indicated that 4th Avenue to Sullivan Rvad wvufd be the quickest way ta reach the Sullivan and Sprague intersectipn. Yhis is primarily due to a right turn at 5ullivan and 4th versus a[eft #urn at Conkiin and Sprague.

Curreratiy there is not adequate pvlice cawerage for the Caunty as a whole. There are plans for expanded services incluciing addi#ionsi officers if mvre funding is matie available ta the ❑epartment. A study was recent{y campleted by the Sheriff's Department Crime Preventian Unit concerning crime rate percentages per type of residential neighbvrhovd in 5pokane County. The data used was frvm 200 Bloclr Wa#ch neighborhnods that were formed from 1979 to 1981 and extended over 13 years to the present. Study findings are as follows: Overati County average - 19% fln or connected to an arterial - 79% Rental hames - 35% Five acre lvts - 30% Cul-de-sac ivts - 75% a. Significant lmpacts - The additApn of 459 new residences anti the related increase in pvpulation will add to the Sherifif Department's responsibility to prvrride adequate police protection to this area of the +Caunty. As pvpulatfon in the area fncreases, sa does the number of crimes committed and the mvre peop4e there is requiring service. Prajec# design includes the extension of Rotchfard Rrive north tv aconnectiarr rrvith Canklin Road. This connectivn wauld make Rotchford Drive a collector arterial, impaCting the existing neighbarhoad vn the cul-de-sac at the nvrth end of Rvtchford Drive. Accvrding to the Grime rate study campleted by the Sheriff°s Department, the Shelley Lake iGraft El5 - 85 Fe6ruary 1994 ~ hames vn the existing cul-de-sac Frave the lowes,t patential crime rate in the Gounty. Achange to an arterial cvadway would put these harnes in the 7 9% potential crime rate category, an increase of 4%. Instead of bein,'~ at a Ivcation with the Ivwest crime rate, the rate at these horraes waufd be equal to'the overa#l Caunty average. The RatchfDrd DrivelCnnklin Raad cvnnection and resultant creation o# an arterial may impact frant yard use in the existing cul-de-sac rieighborhavd. The addition of rnore people tv the area and their increased invbility i`also would limit the recvgnitivn of strangers. Development of the area will result in shart-term ar limited site Visits by constructivn workers, real estate agents, or potential buyers. This will reduce the resident's abEfity to recvgnize pQtential criminal behaViar. c. Mitigatirag Measures ' Many of the potential impacts that could have been created thraugh deVelopment of the prQject site have been mitigated through ttis prapossd sits design. Having a $ignificant numher of cul-de-sac streets and '{anly two access paints into the develapment limits the patent':al tvr burglarid's and vther crimes because the perpetratar can easily be corrrered by respon;cling patrol a~ficers. The private cvmmunity type of design prapased, which inciudes perimeter perming and tencing, typically generates less calls than the grid type of street desigra with multiple access ' poinis. , Residents of the developrxaent cvuld fvrm Block Watches in their neighborhoods.

Widespread participativn in this prvgram can be very effecti►►e in deterring vandalism, burglary, theft, and rvbbery. Many of the residences that will be included irr; the prvpvsed development will be upper-income hames. The owners of these hames wili z~-~ost likely have the resources to install indiVid~ra( seeurity systems inclur~ing al~arrns andlor security lights. The increased property tax revenues generated from the proposed develnpment wili , add tv sheriff, #ire, and sc hvol district funds and rnay heip to upgrade manpvwer and equipment needs. _ 3.2 5criao#s ' a. - -Affected Enr►ironment The prvject site fies within Centra!

Howe►►er frequently there is an uraequal distribution af students per grade IeVel resulting in a schaai reaching capacity in some grades, but nat in others. Therefore even thaugh the aboVe table indicates remaining capacity at Adams Elementary, the schovf is nearing maximum enrollment capacity. Within #he twelVe elementary schoois in the District, 365 students are current9y being bused autside of their home bvundaries to even out the student per grade distribution. The seven junior high schaols may reach this point in the fall of 1993 and require student busing out af Euergreen Jr. High. Yhe District has plans ta eonstruct a new elementary schaQl at Liberty Lake and add twelve new classrovms tv the elementary schools iForvughvut the system. Attendance bvundaries wvuld then be adjusted to ease congestiQn. In addition four new classroQms are planned at the juniar high level. Unlike vther school districts, Central Valley does nat use many portable classranms. Bond issues are the District's primary svurce of fur+ds fvr capiial construction prvjects, including the canstructiorr af buildings and buying partablss. Construction vf the new schnal facilities planned is cantingent upon the passage af a bvrad issue. P'revivus band issves failed in March and NoVember of 1992 and 'rn March o# 1993.

The influx n# students would be gradual Qver the entire~cons#ruction period. Approxirraately 50 dwelling units would be cDmpleted each year,~ and if the phasing schedule fvllows th~e develapment plans, there would be appraximately 30 new students intraduced into the aistrict each year, , { Adams Elementary is nearing its maximum capacity and Greenacres Jr. High has limited rernaining capacity. These schools wouldbe impacted by the additivn of new students from this and other residen#ial develop'ments propvsed fQr the area. fihis may require add4tional busing af students uutsid~ their home boundaries, especialiy within the elementary schaols. Currently there as~adequate capacity at Central Vafley High to accvmmodate #he add~tianal students generated by the prvposed praject.

The majority af the County's Parks are lvcated within the urban portions a# the Spokane Varley, bespite this fact, there are substantial deficits in neigh6orhaad and community parks in the Vailey subareas due - to the high pvpulation [evels. `-Accflrding to iFaB 1989 Sookane Ctauntv Parks anO Recreati~n Plan, the praject site is lacated withain the East Valley SUburban Area. This area extends basically fram Sulii►►an and Fvrker 'Raads mn the west to the Idaho state line an the east and from Foathil4s Ftaad pn the narth to 32nd Avenue on the soudh. There are no necghborhaad She!!ey Lake Drsft E15 88 Fehruary 1994 nr cammunity parks within the East Va3tey Suhurban Area. Since the eastern barder of the 1Nest Valley Suburban ►4rea extends alang Sullivan Road just west of the praject site, future residents of the prapased praject may utilize parks in t'he West Valley Suburhan prea. Park facilities in bvth thess areas da not meet the -needs of the existing pvpulativn. There are three basic classifications of parks within the Spakane Caunty park system; neighh+arlhood, cvmmunity, and regiona1 parks. A neighbarhpad park is intended tv serve residents wrthin a tane-mile radius where the majority of the users vvalk. ldeatty they are lacated in the center of a neig'hborhvad. Children between five and 12 years of age ars the primary users. Desirable size is between three and ten acres, with twv acres per 9,000 in papulativn prvvided. A cammunity park serves more than ane neig'hborhood and users frequently drive ar bicycle ta them. A minimum of ten acres is desieable to secve residents within a twv and one-half miie radius.

Ttre Cvunty Parks Department currently does nat have adequate financial resvurces avaiiable far park land acquisitian. In additivn, private land danaticans to the County park system have slowed substantially due ta achange in tax laws making this less financially attractive. ~ b. 5ignificant Impscts The prapased project will add 459 new residences to an area that was preViQUSIy undeveloped. These new resider~ces will irr~pact tFie Cvunty park systersr by increasing the demand for park space and facilities at exrosting parks in the area. The majority 5helley Lake Dreft EiS 90 Februerr 1994 of the impact wvuld be on flrgsnized spvrts faGilities lball fields3 in the area, stnce these facilities are already heavily vvertaxed. Deuelopment of the praject site will preclude Shelley Lake'S acquisitiDn by the Cvunty Parks Department as recammended in the 1989 Pian. it would not be develvped fvr recreational use by the general public, but wvuld provide recreational Dppvrtunities fvr residents of the RUa. c. Mitigating Measures The ptoposed prQject includes the development of recreativnal UppQrCUf11tIB5 for 5helley Lake residents that vrrill partially mitigate svme of the impacts vn the existing park system. This includes a svft pedestrian trail in the open space cvrridor surrounding the lake. Trail use will include waIking, jagging, cross-cvuntry skiing, and F71rdI1N4ldIlfe Ob5erV8tlof1. Yhe trail will extend dnwn to dhe lake in severaf places ta allow fvr shoreline fishing andlar swinnming access. Ice skatrng cou4d be possibfe an some partions of the lake during the winter. Areas are designated within the plat #or the future develapment of picnic, bsach, dack, and cammuriity center facifities if propvsed by the homevwner's associativn. A future comrnunity center could be lvcated within the existing meat packing building. A!l the existing woaden structures, windo+u►r glass, and mechanicallelectrical systems vvifl be remvved and repairs made ta the ravf as neCessary as part of the proposed project. 7he center could potentionally contain meeting areas and educatianal materials cvncerning wild#ife hahitat enhancemerat and f6sheries management programs. Decisivns cancsrning recreational uses of the apen `spaCe areas wi41 be guided and cnntratled by the restrictiae Cv►►enants. These cnvenants, adopted by the Shelley Lake Hvmeowner's Associativn, will encQUrage recreativnal activities that are compatible with open space preservatian and enhancement gvals and restriet tihose that are disruptive to the cammunity. The additiran of hausing units and therefare an increased tax taase does no# necessarily result in increased pub[ic park serVices fvr the comrriunity. Other services considered mvrs r►ital to public health and vvelfare (i.e. 1aw enfQrcemerrt, public sewer, vvater, and rvads, e#c.) receive a subsfiantially larger prvportian of available funding. If appraved hy the Board of Cvunty Cvmmissioners, deVelQpers may be required ta negotiate Vvluntary agreements to rnitigate impacts on parks and recreation. The praject prapvnent is required to sign s dacument agreeing tu future mit'rgation imposed by ahe Board of Cvunty Commissianers in vrder ta get preliminary plat approval frvm tFee County Planning aepartment. A decisian hy the Bvard of Caunty Cvmmissivners cancerning the amount and applicability of using ampact fees for rnitigation is expected near ths end of the year. 7hese funds cvuld be used to help mstigate impacts of thre prapased deveBopment an the Cvunty park system. Howe►►er, established impact fees are n vt expected to be significan# enough to prvv ide for park land acyuisition any time in the near future.

District Nn. 9's service boundaries extend fram Havana Street on the west to the Idaho stateline on the east and lie basicalfy within the foa#hill areas to the north and south. Statiflns serwing the prvject area are aff manned 24 hours per day by twv or three pevp1e. , n The project vicinity is curreratly senred by Statio f No. 5 Ivcated at Sullivan Rvad and Braadway Avenue, approximately vne mile narth nf the project site's svuthern bnundary. The aVerage respanse time is estimate"d to be apprvximately three minutes fram receiving the emergency cafl to arriving at the scane. Access rouies would be svuth on Suliir►an to 4th and ihen east on 4th,to the project site. This statinn is equipped with a 60[]-galfon capacity engine that requires a minimum of twv pea,ple to _ transpnrt and operate. 7'he statiora alsa has ~~a squad truck containing fir5t aid equrpment and supplies.

Appraximately 50 units are expected to be deaelvped per year, depending an market conditivns. The cumulative impacts of the ,prapvsed acfiivn may result in an increased need for additional manpawer and equipment in the area to provide adequate fire protection. c. Mitigating Measures The develvped prvjeci will haae fire hydrants lacated aecording to County standards thcoughvut the site to prvvide an easy arrd ample water supply far fire frghting ,purposes. The on-site vaater system supplying these hydrants will be sized to praVirfe adsquate fire fIows and designed according to 5pokane County standards and the County Fire Marshall, , Residences and related structures vvill be canstr+ucted in accordance with 5pakane County Building and Fire Codes and the Unifvrm Fire Code regulatians for fire wa#l constructiQn. Restrictions on the aIlvwance af non-#ire retardant building mater'rals - and waod shake raofs wauld help cmntrol the spread of a fire if one were to occur. First respflnse to the devel'oped site wauld be f rom the new Station Na. 7at 12th a nd EVergreen. If a frre were to accur in the southern partion of the site, the fastest res,pvnse frorn this sta#ian wauld be accessing the site fcvm the south vff of 1 Bth AVenue. If nv access to the site is proVided from the sQUth, fire response r►ehiCles from 5tativn No. 7 wauld have to taacktrack to the narth and return svuth fram 4th Avenue. This wrould add several minutes to the ~re5po115$ tIfTIB to tFle SI'Le's sauthern partion. Prouiding a sauthern access route wvuld therefpre keep respanse times to a minzmum. Other options to a full public right-Qf-way ar priVate road to the southern portian of the site were explared with Pauf Ghase, Divisian CFaief af Fire Preaentinn for District Na. 1. An emergency access rnadway cvuld be constructed and closed vtf with an electraG gate. The Fire Department cvuld thera apen the gate using their Qpticam system, which is a pulsating strobe light that is used to turn taaffrc signals green during emergency resporases. Hovr+ever, pvlice and ambulances could not use this access rvute becauss they do not have access to the Opticam systerr-i. Crash gates and roff-oVer berms with landscaping could alsa be a rneans to prvvide access fvr emergency vehicles vnly. The Fire Department wauld not encvurage this type vf limited access because of the damage it causes t❑ f ire engines arad vther emergency vehicles.
