The remaining area woul'd remain zoned UR-3.5 and 5uburban Residential-1 (SR-1). APlanned Unit Develvpment (Pl1Q) overlay with bvnus derrsity is proposed far the entire site, allowing develapment af 459 residential tiwelling units. A diverstty of housing types wnuld be provided includimg 195 multi-family units, 68 manufactured hvmes on piatted lats, 158 conventAonal hames vn small Ivas, and 3$ large lat single-family hornes. The PUD praposed would create a fairly priva#e residentiaE commuraity encarnpassing a varfety of parceti sizes and h❑using densities thraugh the provisivn vf clustered lots. The PU❑ ❑verlay will also prvvide substantia6 areas designated as apen space. The project site contains sensitiae areas such as Shealey Lake and its assoclated wexlands, sloped areas, and vuildlife hahitat. By utili$6ng a PU❑ cancept these areas can be pratected, enhanced, and managed to cvntrol and 1imdt further degradation and actually imprvve existing condstivns. The proposal's abjectiVes are summarized in the following statements: • Develvp a planned residential community that is compatible with #he surrounding neighbvrhand. • Provide substantial open space areas to protect and enhance the site's sensitiae features. • En'hance the wildiefe habitat areas assvciated with Shelley Lake and Saltese Cre+ek to prompte their vngoing heaath and viabi[ity. • Minimize aff-site impacts caused by projsct deVelopment and increased papufatian on-site. • Provide a density transitian betvveen the mult+-famiiy units and smaller manufactured hvrne ivts ta the nvrth and the larger nearly vne acre lvts to the south. + PrpVide a variety ❑f housing ❑ppvrtunities to meet a growing market demand. • Provide paved raads and tnrough carrnections and minimize off-site road impacts. • ProVide an aesthetically pleasing enVironment which will enhance the Shelley Lake FinalFfS 1 April 1994 adjacent neighbvrhoods. • PraVide restr;ctive covenants and c❑ntrals that assure qua6ity contrvl of architectura'l consideratians, Iandscaping and maintenance, place restrictians vn domestic pets and IiVestock keeping, and assrare u6timate protectian of the envirvnment. * Provide a residentia1 cammunity where residents can live irr close prvximity to the natural enviranment, yet restrict their activities to respect the needs of wildlife shar;rtg the site. ~ Minimiae cvnflicts with wiEdlife habitat while providing profect residerats with Dn-site recreatiQnaf opportunities. ~ Prvmvte awareness regarding the site's sensetive features by prcaviding educationaB materials tn residents vutlining efforts cancerning ,protectivn and enhancement af these features. PROPUSEa AC3ION Yhe proposed site is 102.8 acres vfi undevelaped land and 27 acres af surface water (Shelley Lake) tntalling 123.8 acres. The site is lacated in the 5pokane Valieyt apprvximately 1,300 feet east of SuIlivan Road and approximately 600 feet south of Sprague Avenue, A PUD plat vf 459 residential dwe8ling un6ts os proposed witla a rezone of 14 acres to UR-'i 2. The majarity of the site would rernain zoned UR-3.5 and 5R-1. Bonus density is applied tv the UR-12 and 5R-1 zanes. T'he site is in the Ucban and Suburban(+ ) categvries Qf tFae County's Carnprehensiue Land Use Pcan. Yhe Urban category cal9s far cesidentiaE densities between vne and 17 units per acre. The 5uburban( categvey calls fnr residential densities a# betwee m mne a nd fir►e acres pe r dvveiling vnit. The vVera1i site density proposed is 3.7 units per acre, with praposed densities per zoning class6ficativn as foElvws: U'R-3,5 at 2.90 Cvts per acre; SR-1 at 2.09 Ivts per acre; and lJR-7 2 at 13.93 units per acre. The prvpasal incfudes a density transition betvveen the multi-family units and sma[ler manufactured home lats on th@ north and the larger one-half to nearly one acre lats on the south. Open space is designated for 37.9 acres to provide buf#er areas and prvtectian fvr the lake and SaItese Creek shvreline areas, slnpes, drainage areas, and wildlife habitat aeeas vn-site. The praposa6 includes plans to enhance tlae exis#ing habitat areas, while prvvading a soft pedestr@an traif system, educationaf materials for residents, and designating areas tar passibfe future beach, dack, picnGC, and comrnunity center facilities. A fu#ure community center, Wf propased by the homeowner's assaciativn, wQU[d be located within the retrofited former meat pac k i n g facility.

REASONABLE ►4LTERNATIVES Two afternataaes to the 'E]fUpQ58d aG"[10n '[Q fEZOf7e aCld de►J~~op 5hellej1 LaI~e h8Ve al5q been analyzed. They include 1) DeveEopment Under Existing Zaning, and 2) a Nv- Activn alternative. DeVeiopmeni Under Existing Zpning AlternatiVe This alternative would aIlaw the site ta be segregated irata 10,000 square fcaat parcefs for areas zoned L'IR-3, 5and ane acre parcels fvr the 20 acres zoned 5R-1. The proposed rezone to UR-12 and PU❑ ❑VerEay far the entireFsite would not occur. Yh6s would allvw the deVelapment vf 225 buildable parcels, slight6y less than half the 459 units prvpvsed. Under this alternative roadway cvnnections could vccur at Shamrack 'and Gaiway Streets, Rotchfvrd Drtve, and 4th Averaue, increasing traffic counts on all vf tFaese rvads. AII raadways would be developed to public standards. 3'here would be 1ess demand far public serVices than far the prapased ac#ivn alternative due to fewer residents being 6ntroduced into the area. Fevver peaple would result in Eess traf#ic, schavl chifdren, and lawer amounts af irnpervivus surfaces. Withaut tFae ALJD overlay there wflukd be less area designated as o,pen space, affard'rng less protection ta sensitive features and hahitat areas. Nv enhancement of wifdlife habitat areas would vccur arrd there would be nQ additianal restrictions on their use. A homeavvner's assaciation would not like9y be formed, eliminating the restrictiVe covenants pro,pflsed cvntrviling aesthetic and wil'diife impacts. No educatianal vr recreationaC oppartunities would be provided. No-Action Aiternatiae This alternatiVe would totaEly preclude any deaelopment of the project site. EX95tiCig candEtivns would remain on-go6ng. The posrtive impacts on wildlife habitat areas discussed as part vf the Propnsed Action would nat vccur.

The current water quality has been degraded by up-stream and possibly an-site agricultural practices. Fertilizers and pesticides have artificial9y increased nitrvgen and phosphorus IeveGs. Peat mining aperations in the Saltese Flats have added substantially ta organic ~articulate matter inflow, which when decomposed depletes dissolved axygen supplies.

A future cmmmunity dock and deveivpment of abeach' area wvuld afsv require tnis permit if propased by the hflmeowner's assacia#ion. The prajec# wili comply with all the palicies and requirements ❑f the Sharefine Master Prngram. The majarity of the site is zvned UR-3.5, ►ruith appraximately 20 acres aoneci SR-'[. A xnroe change tv UR-1 2 for 14 acres currently zoned UR-3.5 is prapased, with a PUQ vveriay far the entire prflject site. Bvnus density wou@d apply to the l1R-1 2 and SR-1 zones.

With the proposed zorroing and PUa vverlay with bonus density, the aiiowable num,ber of lots could conceivably be 672, aEthQUgh vnly 459 are praposed. Ef prvpvsed under exist6ng zvning with no PUD ouerTay vr banus density, only 385 lots would be • allovued. The existing and propvsed zanes are consistent weth the Urban and 5uburban(+) categories of the Ccaunty's CaimprehensiVe Land Use Plan. Restrictive c4uenants will control the aesthetic appearance of homes and wil9 ensure a safe enjvyahle living environment. A phasing schedule anticipates an eight-to ten- year buiId rrut, with approximately 50 Fats develvped per year. - A professional archaevlagica[ surVey was completgd for the project site and included a recards search and field survey. No significant cultural resaurces were faund and therefare nv impacts are expected tca flccur.

The only cmnnec#iort to the southern street tecmini will be via Rotchford Drive, which wiCl be extended into the plat ta tie directly into Conk1in Raad.

Rotchford C3rave will be the anly publ9c rvad within the plat. The rttajority of the roads wiCl be cvnstructed ta prdvate PLID road standards. The plat wi[I be deuelaped in phases, with 58 units cornpleted hy 1995 qPhase 1) and the remaining 401 unuts completed by 2040 (Phase 2), A traffic anaiysis was Shelfey take Frnaf EIS 6 .4pri1 1994 L prepared to address traffic generatiora, levels of service, and the need fvr improWements to mitigate impacts. ►4t #ull buiEd vut t'here wvuld he a projected 3,750 upd, with approximatefy 2$3 AM peak haur trips and 375 PM peak hour traps. The largest peak hour generated tra##ic occurs in the PM v►►hen 246 vpd w6ll be entering the si#e. The follvwing cvnclusions are dvcumented within the Traffic Anafysis ancluded in Appendix E of the araft EIS. • By 1395 with present background uolumes a[l study area iratersectivras wall operate within acceptable IeVe1s of service; Sullivan and Sprague tLOS Df , Sullivan and 4th (LOS E), Sprague and Conkiin (LC}S C), and Su1liuan and 16th (LOS E). Althvugh these intersections are currently an the margins, there is capacity for additionaE westbvund and narthbound mvvements. • Shvuld the vverall develapment and growth of the area be maintained at neariy 3.0 percent, twv of these 6ntersections- are expected to fail prior to deVelopmen# of this prvject; Sullivan and 4th (LOS F) and Su~~ivan and 16th {L❑S F).

This does nvt mean that this dedelopment will nat add additionar vehicles to the transpvrtatinn system, vnly thaC the intersections for 1335 haVe the L4)5 capacity far the increase in background trafifiic and the develapmen# of Phase 1. - • Wiih the compEetion ❑f full build vut ❑f Phase 2 by 2004, several intersections will need imprvvements to allvw the volume of anticipated traffic tv pass at reasvnabfe levels of service. Su1liVan and 5prague, due to the design of the plat directing trips ta Sprague via Conklin during th€ PM peak haur (by adding 84 - 90 left turns from this project, added ta ihe 1995 expected 420 exist'rng PIVI peak hvur ieft turns), will he pushed beynnd its capacity to serVe left turns. Additionally, the 5prague and Canklin intersect9on durang t'he PM peak hour wi66 drop to an L[]S of EIF, vvith LDS E being the minimum standard for an unsignalized intersection. Aithough t h e ad dition ❑f 58 s ing9e-family homes in Phase 'i and associated traffic will contribute tv the existing traffic currently using the 5ullidan Road and Sprague Avenue CUi'fidOfS, the vnly 1mpac# wvill be that tvwards the cumGlative ayerage daily traffic valumes. Tne pro posed deve9o pment will nvt have any signif icarat am pac# tv 1eVe1s of service through the deVelopment of Phase 1. Spakane Gaunty has identified 1eve9 of service as the indicatar for prvblerns assaciated with developmen# and, therefare, based solely an LOS th€s prnject will haVe nQ impact. However, subsequent develnpment of thrs ,plat in canjunction with deVelopment in and around this area will require the improuement of severaf streets and roads within this general area of Spokane Cnunty. At #he request of the Spakane Transit AuthQrity, a future transit Shelley Lake Final EIS 7 ApriJ 1994 stop and sheiter ar+ea has aIsv been re~erved. This area as lacated orr the south sode of 4th ►4Venue, a djacentto the propased multi-family area, j USt WeSt 0f C3f1f1e Fy R[)ad. AL $he Cof1'lpletlOf1 of Pha5e 2 a tCa$fCC 5agnal may be wacranted at the intersection of . Sprague AVenue and Conklin Road. ThFS signal would be necessitated by a cvmbinatiQn of factors including the contonued area develvpmerat and growth exclusive of tFee Shelley Lake project and the addition of the Shelfey Lake valumes. However, this sigrral shauld be ir►sta99ed when this antersectaan meets at 9east four warrants for signalization, a5 outlined in the Manual ❑f Uniforrn Traffic Corrtrol Devices (ML1TCa). sn addition Cvnklin Road frvrrti 4th Avenue narth xv Sprague Avenue wifl be construc#ed to Spakane Cvunty collector arteriaF standards rnrhich include a4D-foot raadway sectian with curkas, gutters, and siderrvaAks. Due fio the raumber of praposed developments a9ong tFoe Su1aivan Road corridor, it rs unclear whether deVefoprnent of the prvpQSed activn wvuld require the improvements recomrnended due to develvpcnent of this prvject alone. 1Nith the other prvpvsed develnpments aaong the SuE@ivan Raad carridvr, these imprvVements are recamrraended and required ira 5❑me anstarrces to allow through traffic progressoon. However eVen with the deVelvpment of the 5ullirrara Rvad carridor, the development of Phase 1 can be imp feme nted wet hvu# ha°vin g a significant ampact on the ❑vera @6 a rea transportation system. 3.0 Pub[ic Services An additional 459 residertces wifl be added to the respvnsibility of aistrict Na. 5 of the County Sheriff's Department. The added popupation will increase #he number of people reqviring service and the rtumber of crimes cammitted. Project design makes Rotchford Drive a callector arterial, which pfaces homes aIong Ratchfvrd in the 19% pfltentia[ crime rate categary wit h an increa se f rom the currently existing rate ❑f 15%. The rate at these homes wouCd be equal to the averafl average. Howeuer the private cammun9ty type ❑f design propvsed, which inc1udes only two access paints into the devel❑pment and perimeter feracwng, typicafly generates less calls fflr service than the grid type of street design. The develapment will nnt be gated. Many of the upper- income taomes wi9l have resvurces tv instalF individual security systems. Yhe fvrmatiarr ❑f Block V'Vatches will be encouraged. Apprvximately 274 schoo1 children are prvfected at fu1l build vu't of 459 residences. The increase will be graduaC based on an eight-to ten-year develvpment wi#h approximately 30 new students per year. Adams Elementary and Greenacres Juraior High are nearEng capacity and will 'be impacted by the addition of new studerrts frarr+ this and cather residential deueEopments. There is adequate capacity at CentraE Valfey High, Hvwever SchvoC DiStrict IiCo. 356 needs tv complete their existing expansian plans and requests that the deVe lape r negafiiate a volunta ry agreement tv he Ip m bt rgate the proposal's impact on public schools. The new residences will increase the demand for park space and facolitges, with mast 5helley Lake Fr`nad EI5 8 Apr►1 1994 vf the impact vccurrirag an arganized sports facifities. aeVelvpment vf the site wipl preclude 5helley Lake's acquisition by the County Parks Department-as recammended in their 1989 Plan. RecreationaE oppvrtunities will be praVided by the prvject, including a soft pedestrian trail surrounding the lake. Areas are designated for the future development vfi picnic, beach, dack, and cammunity center facilities if prapased . by the hameowner's association. On-site ac#irrities may inc[ude walking, lagginy, cross-cvuntry skiing, birdlwildiife observatinn, fishing, sv►rimming, ice skating, and , rvwing and canoeing. The develvper wili be required tfl sign a document agreeing tv future mitigation measures impnsed by the Saard of CQu nty Cvmmissioners that help aileviate impacts to the Gounty Park system. An add'utiorral 459 res+dences wiff be graduaIfy added to the respnnsibility of Spokane ' Gounty Fire Prfltectivn ❑istrict IVo. 1 oVer an eight-to ten-year build aut period. This may resuit in an increased need for additionaF inanpower and equipment in the area. Fire hydrants wiff be Iocated tktraughout the prQject site and supplied by adequate fire fIavvs. Restrictions will be placed on the use of non-fire retardant building materials and v+,rood shake roafs.

Nfitigating Measures - Page 31. rn this sectior, adiscussion ofutilizing an existing on-site tivel1 to keep She11y Lake at a stable water leVei raises some cvncem. First, our records indicate that the eiectric rneter for this gump 1 was remowed in August of 1988. Th~is leads us to believe that it has been at least 51/2or 6 years since this gump vvas utilized and that Iength of inactivity would have caused the water right to revert to the 5tate. Secvnd, is ow concern atrout the use mf water frvrn the aqui#'er for basically recreational purposes during this particular time vf year. Tt is mvst probable that the lowest levels in the lake would resuFt toward the end of the summer, and be at their wvrst during long hQt summers or drought 2 years. This timing coincides with the aquifer reaching its lowest levels Previvusly, during these cvnditions and during the draught vf 1985-1988, three of Vera's wells had the aquifer level drap to a paint below tfie hattom of t'he welt. Th9s 1awefing of the aquifer left these three welis unable to groduce water vvhen it was needed mnst for vur darnestic and £re protection system A weil pumping 20$ t❑ 700 gaIlvns per minute from the aquifer is nat a significant impact an the aquifer during most vf the year, but taward the end of a long hat surrrummer, or during a drought as 3, experienced in 1986-1988, having this amount vf water removed from the aquifer is signsficant, xhe best use for this water is for damestic and fire protection, service to the residents of the area.

Yes, it is a wanderful neigfibarihvod far many reasons. Many of the people in this neighbarhvod wish to prelserve ths salitude of the area. And G can appreciate this attitude but I canno# suppvrt it cvmpietely. 1 ha►re lived and worked in the Spokane area all of my fife, I have watched it grvw and fiourish. i haue warked Fn constructiora and have benetited by its development, now ! am part of the educational system of the Valley. E have seen many changes in Rt as virell. The increase in s#udent enrollment and the tremendous ancrease in student behavior probiems is evident. But even wrth alf the nega#ive press that brings these paints hvrne, I can stiEl say, the Spakane area is the best place I know of fa raise my famify. I bei'reue that I am part of a greater srrciety. What is gaod for the society is raat always gaod far the individual. This i have a9sv found to be true for persanaf life as well. That €s, what 1 necessarily want, is not what may nvt be best for me in the long run. I have faund that traVeling arQUnd in the vaifey has gatten rnore and more difficult. ! have taken residentiai streets to wark for years, tv avoid congesdion on 5prague avenue. Which o# you haven`t? Now, and preViously the cvunty has required that develvpers put access roads through in thesr develvpmerats. This is nvthing new. As a saciety we need access and we ail use them at times as a quicker route tv samewhere. ~f The underlying attitude thaf I feel cvrroGng from the locai area cvmrnittee as orre that I am nat entirefy camfortabPe with. The uIIV'e're here, fets cfase the gafes" attitude, is what 1sense. ! live in direct connection with the propnsed RiceIShelley Lake deuelopment. E afso have parents that feue on the nart ' h side of the Rice property. I am pretfy sure that had [ not knawn anyane vn the other (north) side of the Rice prvperty, that I too would suppart this petition. But because 1 do, I haWe heard and appreciate another side tv ihe stary+. Our neighbors ta the narth are very concerned taa. Everyone ouer there Fs askirrg the questian, How will our inadequate road suppart 459 new hvmes7 7 The people ta the east an Steen road say, `dvn't send them this way', and it seems that the ,people of #he Rotchfard area are saying the same. I have orae questEan, Where da yvu think all these people are goFng to go7 Caunty government has to decide what is best for aur area. I bePieVe in their judgment. As agrowsng cammunity, we need to ma'ke cancessions that are best for the entire commun#ty. The developer, Mr. Heitman, does he befieve that single access of# 4th and Cvnkfin is what fs best for a cqmrnunity aF 459 nevti+ homes? Do,es that reafly sflund carrect to yvu? i, No one doubts there w'r11 be an increase in traffic in vur area if access raads gv thraugh. But there will alsv be increase access to a lake, the CV piayEng fields and rvads that might make our ne9ghbarhoad richer.

At thistme, neither Steen or Canklin Road is pfannsd tv have an intersection with the future South Valley Rrterial. 5teen Road falls at the three-quarter #v severr-eights ot a mile spacing between Suklivan Road and Flvra Road, creating specific design abstacles in connecting with ei#her Flara Road ❑r the future Svuth Valley Arterial. Whiie Conklin Road, laying at the vne-half male between SuIlivan arad Flvra Roads, woufd proVide a much safer intersectian option than would 5teen Road and be consistent with the gvals vf the SQUth Valpey Arterial. Additivnaliy, please note that the Transpvrtation sectivn ❑f the Drait EIS indica#es that aConklin Road (via 5prague Aaenue) and a 4th Avenue (via SuBCivan Rvad) cvmbened access is much more adwarafiageous than a lirnited 4th Arrertue to Sullivan only access paint. If access were to be prvvided only via 4th Avenue, traffic frQm the Shel1ey LaKe devefopment, your rnanufactured housing community {mvbile hmme park}, and the traffic frvm aver 1000 apartments wvuld all need to gain both ingress and egress from Sulfivan Road along 4th Avenue. The resulting delays and threats to safety on 5ulidVan that a single access paint vvould have is greatly reduced by utilizing the CQnklin Road and Sprague Avenue Antersectavn as the primary ingress and egress paint, rnot ❑nly for tnis praject, but also fvr future prvperties alnng Conklin and narth vf 4th Avenue. 2.

The primary imprflvement is the T-type 6ntersection ereated at 4th AVenue and Conklin RQad, making 4th Avenue the mfnor street and Conkain the major 9ntersecting stree#. This type of intersectian modifieation will make it more inconVenient for the opportunistic shart-cuttdng uehicle ta access Sprague Avenue fram Sulli►ran Road via 4th Avenue, by having to come to a comple#e stop at the Canklin and 4th interseetion. 4. Based upvn your in,put as we6E as others during the prvject scaping process, the best prelcminary design which could be accvmrnvdated by the +exssting Canlclin Road right-of-way, project layout, and roadway safety was praposed.

As was nvted in the Transportation sectEOn vf the Qraft EtS, a madel of the area east a# Progress Road and south alvng SuIIiVan Rvad was conriucted far this project. 7he resuits ❑f this anafysis indicate that the prirnary (90 peccent) destination for vehicles exiting this area is the Sprague Avenue and Sullivan Road intersectian. Based upon time arrd the availability of lanes in tfae area, the quickest way to access this intersectivn is to access Sulli►ran Rvad as sovn as pvssible. Based on this information and the location of existing and prapvsed developrnents south to 40th Avenue, np increase in traffic would be expected to u#ifize the proposed ConklinlR❑tchfvrd rvad alignment. There#tare, no significant increase in vut-o#-area trips are expected through the Rvtchford ►4eres area. HaweVer, due to increased traffic vvlurraes an Sulfirran Road, the an a lysis did Andicate that traffic betweera the existin g Rotchfvrd Acres area and the propased SheEley L,ake area would be best served by this eonnectiorr, rather than having to access Su61ivan Raad Via either 4th, 11 th, 14th, nr 16#'h Avenues.

Aftamant SpoTane., WA 99242 - - (509 )535-1410 I ~~ject AeScriptifln The proposed plat of ShelYey Lake P.U.D. is a 123.8 acre planned unit develapment c❑mprised of 264 single-family residential lots and 196 multi-family residentiall units located east of 5ullivan Rvad and 5outh of Sprague AVenue in Section 24, `I'.25 N., R. 43 E.W.M. Ttae tapograpby of the site varies fratn gently rvlling at the southermmost narthernmo5t portivns to steep slopes alvng the lake frantage and alvng the east boundary. 1he project's most pPvmineat feature is Shelley Lake which is bordered tay the prvposed plat an all but the ea.st 5icie. Shelley Talce acts as a natural 5unnp area far seasonal flvws from Saltese Creek which drains a fairly significant drainage basirn tv the €ast and south. Since 5helle}+ Take has nv natural outlet, all stat mwater which enters ihe lake is disposed of through percolatian and evapvrataan , ' 100-Year F1oad Piain The 100-year fload ~lain elevatian is defined as the waeer surface elevativn that would have a statistical grobability of 1 percent of vccurring in a.ny given year. A 100-year flvod plain elevatian of 2427 (USGS Datum) has been established by the Federal Emergency Management Agen~ (FEMA) for Saltese Creek at the Steen Rvad bridge which is located upstream of amd ta the east of 5helley lake as shown vn the attached FEIMA map. Elevation ronfivur 2027, as iadicated on A6ttachrrzent #1, is prQposed as asa.fe eTevation an order to establish minimum finished flova elevations for lvts adjaGent to 5helley Lake (i,e, all finished floar elevativns will be at eleVativn 2028 vr higher). Located nartheast of tne site is a natural channel Ieadirig ta ihe Spokane Caunty/Shelley T ake GraveZ Pit which acts as an emergency vverflow far 5aitese Creek and She11ey Lake. Because of the nature a£ the site and the fact fhat the tngsail has heen removed, the gravel pit is capable of trerraendvus percalacion rates estimated at 500 inches per hour. Far this reasmn, the ehanne1 and the gravel pit shvuld be preserved to provide a margin of safery far cantrolling flovdrvaters. As indicat~ed e~n Attuchrnent #1, the only buildir~g lats w~iich lie within the Z~127 eleV~,tivn contour au'e Lats 33 through 36 in Block 1. ~ Svi1s ne attacbed Sails Map, obtained from page 76 of 5oi1 5urvev for S~aakane Cauntv. Wa...ShinLrton, shows that the site primarily consists of Garrison series sviis which are gravefly, svmewhat excessiaely drained svils typical of the Spokane Varlley. Alsv Fresent on the site is a Mery small area of Sgokane series soils which are well-drained, moderately cvarse-textured soils averIaping bedrvck. Stormwater llisposal Other than the Saltese Creek watershed, the proFased project site +does nat contain any majnr drainage cvurses. The ten-year design starm runvff fram localized an-site basirs will be dispased of using '268' grass percoiation area,s and drywells in accordance with ihe Spv'kane Gounty Cmide3ines f r~tormwat,pr Management. The svils on the prvject site as andicated oa the Svi1s Map are cnanpatible with the use of drywells an►+d grassy swales. The variahle topography of the site will likely result in avariety of methdds to capture and dispvse of mnvff fxom the road impervious surfaces in order to pravide '2[]$' swale areas which are acceptable from the standpvints of constructability, Maintenance, and aesthetics. In arder tta mitigate many enviraamenfial impacts conoerning the lake, all direct runOff fram the develnpment will be isolated fram the 1ake. This wi,ll be accampiished with the use of gra.ssy swales constructed upstream of the trail access as showal onAttachmenx #L A typical sectiam depictiag the access trail and grassy svvale cvnf'iguratiaa is shorvn on Artachment #Z "The lalce rvill be protected during construction thraugh the use of temparary ervsion control rneasures including siYt fences and after canstruction hy freseeding excaVated aQd otber disturbed surfaces. Conclusions 1. , Through the uss of respnnsible starmwater management practices, the _ envirQnunental integrity of the Shefley Lake site may 1ae maintained in the propmsed developed candition. - 2. The 2027 elevatian cvntorar as eurrently estabIished by FEMA for Saltese Creek at Steen Road can be safely used as 100-year flood e1evation around - the lalke. , a 3. The site contains nv other major drainage basins. - 4.

The survey was undertaken as partial fulfillment of a cont_raGt betweern the Center far Northwest Anthropalogy of Washington 5tate iJniVersity and Ramm Assaciates of Spakane for N & HInvestments of Spvkane. The survey was conducted by members of a six person team from the Center for Northwest AnthropolQgy Qn July 23, 1933. The gaals of the archaeological survey, as stated within the 5cope of Wark, .included a surface survey for cultural d[[3tEr1al5. - The surface survey was ta be augmented by subsurface testing where law surface visibility might impede the discovery of Gul- tural material. Site lacations and hasizantal baundaries were ta be determined for all cultural resouraes 1ocated, and recorded an replica []SGS maps, Additivnal aspects of the 5cope of Work included praductian of a progress report within 14 days of contract executivn and submittal of a final repart within 35 days of cantract executian. - The pxogress repart was SLibmlttEd ta Patti Idlvf of Ramm Assvci- ~ ates an Aug,zst 2. 1993 .This f inal report represents the comple- tion of obligatians stipuiated in the 5cvpe ❑f Work. MAHAGEMENT SIIMMARY An extensive surface survey of the project area surrvunding 5helley Lake was conducted Qn July 23, 1993, by a crew of six _ peaple fram the Center far NvrtYtwest Anthrvpvlogy of the Depart- ment of Anthrapolagy at Washingtan State University. Surface survey coverage, consisting ❑f regular transects with 5 m tv 15 m interVal spacing (contingent on speci£ic situatiQnal needs), was augrmented by the excavatiean of 116 shoveI prabes, warying between 15 cm ta 57 cm in deQth. Most of the area has heen disturbed by cvnstruGtxon and operation ❑f the Rice Country Meats facilities and the associated plowed fields surroundirsg it. pda evidence for significant cultural, resources was identi- fied during the susvey. A single end battered cabble, located southeast of 5helley Lake, represents the anly possible prehis- taric cultuxal artifact. As such, the propvsed project should not adWersely effect cultural resources. In the event that archaeo- logical materials are encountered during the project, a qualified archaeolagist should he nQtified tQ assess the significance ❑f the discovery.

Shelley Lake is asmall (aFFroximately 25 acre) pond lacated sauth rsf the Spokane River (river raile 88) and Interstate Highway 90, approximately 9 miles east of Spokane and 20 xniles west of Caeur 0'Alene. The proj ect area fa1ls within what is typically referred to as Spokane Val- ley, ❑r in histQric times as the Spokane Frairie. Access to the , praject area is scauth via the Sullivan exit fram Interstate - Highway 90, and east on Fourth Avenue, ENVIRmI+1MENT The project area ❑ccurs within an ecotonal setting between the Northern Rocky Mvuntain PrvVxnce to the north and east, and the Columbia Sasin subprovince of the Crslumbia lntermontane Province to the sauth and sauthwest (AlYisrsn 1968). The transi- tion from caniferous forest tn grassy steppe results in alargely p' apen cQniferaus parkland environment. Ecvtonal areas are typical- ly cflnsiaered t❑ pvssess a wider selectian of resources, cvntain- irsg e lements af bath ecosystems (Odum 1971). Thoms (1991) states that the Middle Spokane River Valley as a whale would support anly moderate populati❑ns af game animals and fish species, but would still have had greater productivity than surrounding area5. M❑st of the area is classified to the Pinus-Festuca (pande- rvsa pine-bunchgrass) veqetatianal zone (Daubenmire and Dauben- mire 1968), The farest community is characterized by varying , mixtures and densities ❑f ponderasa pi,ne (Pinus ponr3erasa) and aQUglas Fir (Pseudatsuaa menziessi), and sparse undergrowths of - kaunchgrass (Festuca idahoensis) and wocady shrubs. The present fflrest ecasystem appears ta have expanded inta the area smmetime between 5,000 and 2,500 years aga {Mack, et a1. 1978; Mehringelr 1985}. 'The occurrence of the Spokane River and other water 3aodies nearby provides some riparian affects to the Vegetatran of the area, such as the increased ❑ccurrence of woody shrubs anc3 grass- es, but this effect diminishes as one moves away from the river. The increase in vegetatfon prQVides greater amaunts of feed fvr animals, typiaally resulting in relatively higher animal popula- tians or cvncentrations, as well as iriCYBaS~.'S in berry and other vegetable craps. Weather patterns in the middle part ❑f the Spokane River Waliey generally consists af dry and mild sumners and cold humid winters. Precipitation occurs mainly as snowfal1 during winter, and aVerages 17.5 inches per year. Precipitatian for the area mirrors the vegetational pattern as ]oeing transitianal from the 3 drier areas to the sauth and southwest and the mare maist envi- ronments to the north and east. CUI,TiTRE HISTORY Numeraus cultural historical set}uences have been postulated - far the Columbia Plateau. Most are built vn interpretation vf excaVations conducted in localized areas. Sequences have been prvpvssd fvr Middle Co1umbia (Galm, et al. 1981), the Yakima area (Swansan 1962; Nelson 1969), and the Iower Sna3ce River area (Leanhardy and Riae 1970, 1980), as well mare general regianal seqruences (Daugherty 1959, 1952; Warren 1968; Hrowman and Munce7.1 1969). Each begins with a locai vara.ant o€ the Faleaindian perivd and continues through several phases whieh, despite aften having different names, are remarkably similar in their periadizatian. The following summary as from Andrefsky and IDePew [5992:10-11) as adapted frvm praper (1992: 2. 10-2 ,11) . The Windust Pbase dates from agpraximately 10,000 t0 8,000 years ago. The diagncastia characteristic af this phase is a shart aladed, shoul.dered lanceolate point with astraight to cantractin$ stem and a straight ar slightly cvncave base. Tools assemblages tend to kae daminated by edge-mvdified flakes of siliceous materials. other taals found in Windust assem}alages include knives, cvbble tQals, and hone implements. Bone and antler spurs suggest the use of the atlatl, and eyed bone needles indicate clathing = manufacture. Lithic tool manufactu=e involved the extensive use of siTiceous materials rather than basalt. No dwellings have been found at 51te5 af ttais age; the campsites hawe generally been found on upland terraces, alluvi.al fans at mauths flf canyans, and to a lesser extent in caVes and roakshelters. Present evidence surggests Windust people were mobile hunter-gatherers ar faragers whose subsistence was deriVed largely from hunting deer, elk, pranghorn, ra►bbits, beaver, and waterfowl; river mussels were also used. There is n❑ present evidence af plant processing equipment. The eascade Phase spans the pericad from 8,000 to 5,000 years ago. This time period is rlivided inta Early - (8,000-6,700 B.p.) ana Late (6,700-5,000 B.P.) phases. Although bath subghases are characterized by leaf-shaped 3anceQlate paints (~Cascade), the I,ate phase is distinguished by the ac3dition of large side-notched d,art pvints (Cold Springs). 5tone atiatl weights and tabular and keeled scrapers ocaur in assemblages for the first time. The presence ❑f fish banes and plant processing implements thought to have been used for grfnding seeds rather than roats suggests more sedentary settlement pat terns. EVen with t3ais apparent braader subsisternce base, however, hunting appear~ to haWe continued as the most impv_rtant saurce of sustenance. Bense (1972) suggests that 4 ~d Gascade assemblages give the impressiQn of groups becaming . more adapted to their settbng, particularly in the use of laCally available tavlstones such as basalt. HQwever, more recent evidence suggests that nonlvcal lithic materials were used as much ❑r in greater frequency during this phase than were lacal xaw materials far making artifacts ~ (Andrefsky 1992; Sappingtan and Carley 1984). Open settings as well as rockshelters and caVes were used as site locations during this phase. - The Tucannaa Pbase is dated from 5,200 to 2.500 B.P. During this phase there is evidence for increased sedentism ~ in the form of large viilage sites and settlements. The artifact assemblage, hawever, appears crude and unsaphisticated compared to the earlier and later phases in the sequence. ProjectiYe point forms consist of types witn shart blades, shoulders af varying prominence, and contracting stems; the secvnd mast comman type is notched on the side near the base or at the corner. Scraping taols, net sinkers, hopper martar bases, and pestles are also commvn to the assemblages. Bone shuttles indicate nets were manufactured. Tn additian to deer, elk, and pronghorn, bison are added to the menus of some groups, and river mussels are mare intensively exploited. The Hasder PBase dates fram 2,500 years ago to A.D. 1300. Like the Cascade phase, this phase is divided _ intv Early and Late subphases. It is characterized hy - housepit Willages and the semi=permanent winter village pattern. Projectile points of this phase tend to be smaller and well-made. So called Snake RiVer carner-notched points, lancealate and pentagonal knives, mortar and pestles, bane awls, ornamental beads, and gaming pieces are cvmmvn to many assemblages. The Late subphase is distingaished hy increas ingly smaller point forms than thflse in the Early subphase. Hafted end scrapers are comman to assemblages frem bath subphases. The ethnagraQhic periad can be thought af as a time that post-dates the acquisitian of the harse, which in creased mobility, and the addition of Euroamerican trade goods to the indigenous artifact assemblage. Hause pits of this phase tend to be circular in plan-view. Artifact assem blages typically cantain smaTl corner-nvtched and stemmed paints, end scrapers, lanceolate and pentaganal knives, edge-modified flakes and spalls, pestles and hopper mvrtars, net weights, bane awls and matting needies, composite har pvons, and twined basketry. 5 Iw , Vf HISTARIC OVER'oIEW Spokane county possesses a rich histary bvth in terms of local and regianal develapments. A detail descriptian af the area"s hastnry can be found in Larsvn (1991), in which she di-- wides the history of the area inta three periods, including 1) fur trade to settlement, 2) early settlement, and 37 ci.ty of Spokane and Spokane Valley deVelapment. A brief summary wi,21 be gresented here, with particular emphasis on events near the project area. The Spokane House, located near the confluence ❑f the 5pa- kane and Little Spokane Rivers, is reported as the first Euroa- merican settlement in trie Eastern washington. It was lauilt by the Nmrth West Campany as a fur trada,ng po$t in 1810 under the direc- F_ tion of Finan McDonald and Jacques Finlay (Meinig 1968). It was lvcated an atrail network which had heen used by the Native Americans in the area and continued to be utilized by explorers, missionaries, the military and ❑thers. A rival fur campany , (PaGific Fur Company) established a pest called Fart Spokane nearhy in 1812. The Spokane House and Fort Spokane serWed as a foca1 paint for travelers in thQ Nvrthwest far nearly adecade. by which time hoth cvmganies relacated their interests t❑ ❑ther parts of the Northwest. PriWate individuais continued to vccupy the sites in the years fallawing. Ant❑ine Plante built a ferry crossing the Spokane River irainediately Narthwest a€ the praject area. Grertiited as bezng the first non-Indi.an cammercial ferry in the area (Berglund 1987; - Fahey 1988). In additian, Plante grew erops and raised harses and cattle, includang saVeral milk cows (Peltier 1983), the surplus ❑f which hs traded to travelers. He also hired himself out as a guide fram some of earliest exploratian in the area (Larson 1991), inciuding Governar Isaac I. Steven, during his search fnr a rai]Lraad route from the upper Missouri River ta the Pacific C3cean. The 1850s marked a perivd ❑f tensiort between Native Ameri- ' cans and Euroamericans in Eastern wastsington (Peltier 1983). Hostilities beqan ta a"rise due to widespread dissatisfaction among the Nati.ve Americans with terms of the treaties being impased upan them, as well as with increased encroachment by miners and vther settlers. 5ma11 scale hastilities af the mid- t❑ , late-1850s escalated inta a fuT1 scale canflict during 1858 (Larsvn 1991). At that time the combined forces of the Coeur d' Alene , Palnuse, and Spokane Indians defeated a pooriy equipped military contingent under Colonel Edward J. Steptae near Rosalia, WaShington. The U.S. Army respanse was ta send Calonel Gevrge Wright and 704 trovps to the area. They arrived in the Spokane Valley in August of 1958. A massive force vf Native American groups gathered at Spokane Falls, including members of the Spv- kars, Caeur d'Alenes, Falvuse, Yakima, Kalispel, Pend oreilles, , Cvlville. Columbia, akanagan, and several Nez Perce, The Iong range rif le f ire of the Army proVed to be tvv great flf an advan- 6 ~ tage, and the indians were severely defeated on September 1, 1858, near the Four Lakes area. aWer the next fvur days Colonel wright and his troaps waged battle against the native farce alvng the Spokane Valley, thvrvughly defeating them and crushing the indian uprising. - The defeat of the Indian forces set the stage for subsequent deVelopment of the Spokane Valley. The first bridge cxossing the - Spokane River was built in 1864 by A.C. Kendall, wha operated the toll bridge at Spokane aridga near the current Washxngtvn/Idaha 'border until spring floods washed the bridge out the next year. - It was rebuilt by Timothy Lee and Joe Herrin. A secQnd "free hridge" was built by Isaac Kellogq in 1865 upstream from Plante's ferry. Even sa, by 1872, the Spokane Valley area had only a few ~ permanent settlers (Doyle 1932), Mast of these lived in the new cammunities at Spokane Falls and at Spokane Bridge. ' The town af Trent, lacated just north af the projeat area, was the next center of settlement in the area. It sprang to 1ife during the mid tv late 1870s, with its greatest development accurring during the period when the Narthern Pacific built their ~ railroad bridqe across the Spokane River there in the late 1870s. The canstruction of the railroad, which extended fram Du- ' luth, Minnesota, to Kalama, Washington Territary, prvvided a double blessing far the Spokane Valley area. The initial benefit arvse for the commerce associated with the constructian crews. Boarding houses, general stores, and saloons reaped prafits fvr the men working on canstruction. Secand, and perhaps more impor- _ tantly, the railraad proVided an access to distant markets far both distribution af their grQducts as welY as access ta less expensive praducts. Numerous other industries fueled the growth of the area, althaugh mast of these industries experienced a moom and bust cycle. A gold rush in nozthern Idaho and a3ang the north fork vf the Coeur d'Aiene River in the winter of 1883-1884 lead to the development of Spokane Falls as a major outfitting and staging areas into that area (Larson 1992:6.21). Ranching and farming played central roles in the ear1y days ' ❑f the develoQment of the Spokane Valley. Farming was Timited in the late 1800s due ta the limited rainfalT in the area. Grain crvps were the major products with mast vegetable craps limited to personal needs. At the turn of the century, lrrigataan projects were undertaken by the Spokane Valley Land and Water Company, 3ater called the Spokane Canal Company (Larsan 1992). The irrigatian prajects used the waters of Newman, Twin, and Liberty Lakes as ameans af suppasedly turning the shallaw, graveily sQils af Spokane Ualiey int❑ prime farm and orchard 1ands. The early part vf the 1900s witnessed an explosion in archard ana farm develvpment. For a short time, same of tha farms experienced increased production, but this was to be short lived. 7 I ~ Hy 1920, lake levels had drQpped tv a point which made tMe irri- gation systems useless. [7nderground water saurces were exploited using wells until a diversion system from t'he Spokane River was constructed an bath the north and svuth 3aanks gf the raVer by prvperty owners in the area. The Spokane canai, as the diversion system was called, was cvmpleted in 1924. Despite the success that some individual vrchards and farms were eacperience, 3ay 1922 it became vbvious to the farmers in the area that the snils af the Spokane Valley were inadequate to support the heavy use practiced in the early 1900s. The soils required heavy fertilization which raised the cQSt of prvductian to alevel which made the v+enture barely profitable. Peaple began cutti,ng back an their ❑rchard size, often pulling ont entire orchards. A, heavy freeze in 1923 further complicated efforts ]oy the farmers. The fina1 blow to farming efforts in Spokane Valley was the depacession af the 1930s. Thase who ttad managed ta oVeXCOme the earlier problenas of changing markets anri exhausted soils cauld _ not withstand the econcamic crash vf the Great Depressian. Spokane Valley shifted fresm agricultural to residential deve3apment. By the mid 1950s, residential devslapment had all hut tatally re- placed the orchards ❑f Spokane valley. PREVIOIIS A1tCHAEQLOGICAL RESEARCH = Very little systematac archaeological research has been done along the Spokane River, Research that has been dane has focused on the area ❑f the Spokane House-Fvrt Spokane camplex near the junctivn vf the Little Spokane and Spokane Rivers. Much af the work canducted along the Spokane River upstream from Spokane Fails has cansisted af small field surveys, seldam incorparating extensive areas and rarely resulting in the recoVery af cultural resources (Bensvn 1979; Lindesaan 1979; Lindeman and Rice 1981; Rice 1978,1984, Salo 1986; Wessen 1988). Recovery af cultural - resources has largely been limited t❑ sites irnrnediately borcYering the Spokane River (Draper, et al. 1991; Qraper and Olsan 1991). - The earlxest excawatian reported i.n the literature fvr the Spokane River were associated with the Spokane Hfluse-F'ort Spokane site (455P5) , which was excavated frvm I950-1953 (Caywvad 1954). Evidence af the structures of the historic trading past were dacumented by these efforts. The area received further attentivn im 1962-1563 [Combes 1964], during which time the lvcati,on of Fort Spokane was confirmed as well as dacumenting the gresence af aprehistaric presence in the locality, although the histvric eampvrnent was the f ocus of ef forts . Anather prehistaric site (45SP92) was lacated approximately one mi le upstream f rom the Spokane House JFort Spokane complex. anly lzmited surface collectian and minQr testing has been con- ducted at the site (Larsan 1985; Andrefsky and DePew 1992). 8 Recovered artifacts suggest a late prehistQric/protohistaric campanent. An addition prvject wnrth nate inVVlved limited docu- mentatian of a pithouse laGality (455P37) an a terrace near oeep Creek (Hryan and Swanson 1952). Same minar testing was performed at a site (45SP6) near Spokane Falls Cvmmunity College in 1973 (Q'Neal 1973). The test- ing was done by students under the di_rectiQn of Jerry O'Neal of Spokane FalIs Cvmsrunity Callege. The site's assemblage suggests perivdic use over the last 1000 years, Numerous sites have been recorded in Riverside State Park (Larsan 1987). One 51ter 45SP91, in the Bawl and Pitcher area, is of special interest in that the site's assemblage and setting - suggest mid-Halocene ar greater antiquity (Larson 1985), The only large scale archaeolagical project on the Spokane River accurred in conjunction with the Centennial Trail Prvject (Shalk and Wyss 1989; Wyss 1989; Draper and Andrefsky 1991; Andrefsky and DePew 1992). The primary purpase of the praject was locating sites along the right of way of trail construction, as weli as identification of significant sites which might be ad- yersely impacted by trsil construction andtor use. A total of 72 sites were located as reexamined dusing this project, which was conducted frmm 1989l1992. 9 CHlPTER 3 AACH"DLOGICAL BtTRVEY TN'MODUCTICIH This chapter of the report provides information cvncernirtg the archaeolagical survey conducted at 5helley Lake. The section includes a description of the matihods employed during the survey, as wsll as a discussion of the results far each of the areas surveyed. . METHDD8 AN]7 1tESdLTS Initial review of the praject area based an prvject maps and field observativn suggested that survey raould be mast efficiently canducted by dividing the l.arger prcaject area intv faur subareas (areas A-D, Fig. 2) surrounding Shelley Lake (wMich made up aPproximately 16% of the tvtal prajeat area). Decisians cancern- ing area boundaries were based on a cvmbination of geomorphologi- ca3 features and Euraamerican features such as raads and fances. Area A consisted of the northern part of prvject arear extending approximately 40 m s❑uth past the access road tv the Rice' s Cauntry M+eats buildings (see photos, Figs. 3-5 The east and west baundaries of area A carXelated with the project bound- aries. Area Aincluded all of the buildings assr~ciated with Rice's Cauntry Meats, and made up approximately 17% ❑f the - praject area. Area Ainciuded an open field, a dilapidated - slaughter hause, three autbuildings, a parking lat, and an access raad system. The apen fxeld was heavily glowed with little ta no veqetaticanal cDver, and as such very hxgh surface visibilkty. The area around the building was heawiiy disturbed araal showed eVi- dence of haVing been filled in griar to cvnstructian of the buildings. Coverage of Area A was conducted by the entire surVey team (six peaple). A total of 24 north-svuth transects (fcaur sweeps of s1X people) were walked acrrsss area A at apprvxirnately 10 m intervals. A slightly zig-zag path was walked by eaGh individual to maximize coverage. Fertyeiqht shovel probes were aug during the survey to insure that subsurface cultural materials were not being missed. Shovel probes varied between 20 cm t❑ 57 cm below surface. Fill from the shav+e1 prvhes were carefully trowelecl through and placed back in the shvvel prvbe hole. ❑epasits in the area were made up of adark. organic rieh, upper gravelly sandy matrix averaginy 25 cm to 30 cm in depth, fvllawed by a lighter brvwn gravelly matrix. Differences in the twa horizons appears to be primaary in ❑rganic content, making the upper level much dark- er. This upper ievel undaubtably correlates with a plowing zvne. No eVidence of cultural resaurces was laGated, Qther than a very disccantinuous scattering of recent garbage. 10 - . _ ~ c ~ ~ ~ ■ ` AREA A ~ ~ ~ . • ~ ■ ` ~ AREA C ~ ~ ~ • ~ , AREA B .a PROJEGT ; - .

The northern bQUndary of area B was marked by Faurth Avenue, and cvi,ncided with the prQject houndary. The eastern boundary ran directly south frvm the junctaan of Fourth Avenue with Cvnklin Road to the share of 5helley Lake, follcswing the shareline scauthwest ta the mast westerly ex~ension of the lake. The bflursdary of Area B then runs immediately west and fallows the project boundary alang its western edge north to Fourth Avenue. Area a incorgorated apgrvximately 15% of the project area. Tt cQnsisted of a heaVily plowed open field on a terYace approximately 10 n above Shelley Lake and the sloping terrain running doran tv the lake. ApQrvximately midway between the upper plawed terrace and Shelley Lake a dirt access road vn a remnant or created terrace accurs.

A total of 25 shovel prDbes were excavat- ed, ranging in depth between 21 cn t4 33 cm beTow surface. Depas- its virtually identical ta thase in Area A were encountered in Area B. vne gossible basalt flake was recavered from a shQVel pro}ae in Area B, but the lack of ather cultural materiai suggests that this €lake might have been created by plawin,g activities. W Area C included the lands bordering 5he1ley Lake to the north, east, and sautheast (Fig. ' 7). Yt included an inte _rmittent stream and pand, bounded ta the east by the project bvundaries, ineorporating approximately 10% of the praject area. The vegeta- tian ccrwer varied, but mostly ❑ffered high surface visih~lity. The area consisted largely of a fairly steeg slQpe running dQwn to tYte shares of Shelley Lake. This area was also surveyed by a three person crew. The team surveyed the area wa,th one sraeep, running west t❑ east in the nvrthern sectian of the area, and north to south in the eastern sectian of the area. Transect intervals varied fram 5 m tQ 15 m depending on the width of the survey area. F"rsurteen shaVel Frvbes were excavated in Area C, ranging in depth from 15 cm t❑ 25 em.

Five categories are designated in the listing. Included are Unit, Level (abbrevs- - ated LU), depth of eXGavatlon of the shavel prabe below surface (BS), Matrix, and the presence ar absence of Cultural Material (t:ult, Material) . The []nit designation is a field xdentification nnmber used by the Center far Nortnwest Anthropolagy during archaeolvgical sur`reys. The twa letters which start the unit designation are the initials of the indiWidual who dug the probe, and tne nutnber whiah fallaws is assigned in aequential arder. The purpase ❑f this designation is to cross-reference Field nntes taken on each shove1 probe by the individuaY to a field map ora which Yacation of the sha*ael probes are platted. The Level designation is typica11y used in areas where multiple natural and/or cultural strata are dug thraugh during excavatian of the shovel probe. A numher, starting with S at the surface, is assigaaed tv each recvgnized different strata. This allaws for increased control when cultural materials are encaun- tered. The B5 designation prDvides the depth belvw surface in centimeters of the bottom of the Level of the Unit being cansid- ered. The Matrix designation is a field description of the depas- - its contained within each level. Far the 5helley Lake Prajecti ~ anly two strata were reeogniz ec1. The upper most depos its were dar9c, organic rich, gravelly materials. Tn some shavel probes, a 3ower, lighter graveJ.ly material was encourstered. This lvwer level differed from the upper leVel primarily in that the upper layer contained more argania material, making it darker in ap- pearance. The Cultural Material categflry signifies the presence or absence af cultural artifacts. During the ShelYey Lak+e 5urvey na significant cultural resaurces were iQCated. A-2 U.+1IT LV ES MATRIX C❑LT.

This plat wourd be constructed witliin that,area knovvn as "Phe Spvkane Valley within 5gakane Cvunty, approximateiy 14 miles east of the City of Spolcane Central Business District (CBi7). The sire is appraximately vne-half rnile south and east of Sprague Avenue and Sullir+an Rvaci, respectiWely. At this time the site is nnt bvunded by any roads fvr any apprecxable distartce. Tv the svuth there are three street terinini at the plat baundary, Rotchford Arive, Galway 5treet and~ Sharrirack Street. It is anticipa~~ that tfie anly cQnnectivn to either of these streets will be via ltatchford I?rive, which will be ektended through the plat w tie direcWiy into Conklin Rvad. Ta the east there is nv adjacent rvad; vvith Steen Roaci providing the closest access at the yery southeast portian of the plat. At this time there is not expected to be any through connectavn iv Steen Road. To the TiR7It7We5L' the site is btrunded by Cvnclin Road tv it's terminus and ~ intersectivn with 4th .Ayenue, which qcontinues ad}acent to the plat west far ane-quarter of one mile. It is expected, and shawn in Figure 2, tkat Cvnklin Rvad will be extended through the plat tv tie directly intv Rotchfvrd DriVe, while at the same time the intersection of 4th AVenue and Conklin will be recanstruct,ecl sv ihat 4th Avenue will make a currre tv the svutheast and tie inw Conlclin at a 9()-degree a.ragle. P;rirnary ingrcss and egress fram this alternative wiU be via - Conklin Road nvrthlsvuth directly to Sprague Aver►ue. It is expected that 4th Avenue will proVide service directly tv a small po ~rt.ivn of the pmpvsed multi-family, whach will be consistent wwith the vther 700-plus apartments currently existing ar propvsed alvng 4th Avenue. The entire praject will be canstructed in phases as andicated in Tab1e 1.

Hawever, the existing Sullivan Road and 4tbh AVenue intersectivn, currently operates at ar near an LC35 of E, ~uring the PM pealc hvur. ~ Althoug'h not below acceptable levels, both the Sullivanl4th and fihe Sullavaia/15th have ievels of service values of LOS I3, during the A.M and PM peaks, respectively. A closer analysis of these intersection 1eVels of service reVeals the fvllowing infvrmation. Sullivan Road artd 4[h Aven+ue - As seen in Table dV"a. 4, this intersectian, during the AM peak hour operat.es with an Li]S of I], and amwrve capacity of 175 passenger rars per haur (pc.ph). As described earlier, fnr unsignalized intersections, the LOS fvr the intersectivn is the lvwest IAS experienced by any Qne leg of ihe intersection. The AM peak hvur LOS of I7 at 175 pcph, ~ is for the eastbaund leg of the intersectivn. For this pro}ect it should be noted that the westbound leg, vr the leg which has #he patendal fvr traf'fic frmm this propxasal, has an AM peaTc _ haur LvS of B with a reserve capacity of 312 pcph. For the PM peac hvur, as shawn in Table Na. 4, this intersecavn aperates with an L[)S of E, with a reserve capacity of 76 pcph. Urfilike the AM peak hvur, hvwever, both the eastbaund and westbound lcgs of t.his intersacmian €unctian at vr near the same 1evels, glease review the appendix for LAS ralculations. The primauy reason far 4he poar IeveT of servitce is the cvnfiiicting left tums as well as the moderately high to high thrnugh traff c valumes both directivns on Sullivan Rvad and the fact that there is raa turning lane or refuge fvr left turns at this intersection. Sprague Avenue and ConkTin Road - As shvwn in Tabte Nv. 4, during the AM peak hvur this intersection functians with an LQS of A, and areserve capacity of 424 pcph. However, during . Inland Pac,,;fic Ereginnreri,ng Campany 20 Sherley r4ke nA ~ r the PM peaak hvur the L[35 for this fintersectivn falls to and LOS of D, with a reserve capacity of ldl pcph. ?his le►+e1 of service isl, far the svuthbound Ieg of the intersectivn. T'he nQrthbvund leg, or the leg which wil1 be dir€.ctlyl affected by this pmpc3sal, currently operates during the PM peak hour with an LQS of C, with a mserve capacity of 274 pcph. This lewe.l of service ~ designation is adeqware far an urban unsignalized intersectian. It should be nQt,ed that the snuthbaund L95 of D, was for an m~tersection leg wluch had orly 91eft turns and S right turns. Secdlivcn Road cud 16rh Averrue - As shown in Tahle Nv. 4, during the AM peak hvur this inmrsection ❑perates with an acceptable LOS of C, with a reseenre capacity of 273 pcph. As with the vther intersectiuns, during the PM peak haur the 1cve1 of service far this intersectivn falls ta an I.C}5 of I7, with a reserve ~acity of 121 pcph. Again, the identified Lv5 is for the far Ieg, vr eastbound Yeg of the intersection. 'I'he near leg, ar the leg with the potential to be af#'ected by this prapvsaT curtenily aperates during the PM geak haur with an LAS of B, with ; areserve capacity of 385 pcph. It shvuld be neted, that SulliVan Rvad funcaans as a high commuter route between Interstate 90 and thvse nesidential areas sauth of iSprague Avenue. Therefare, the dissirnilarity in thmugh valumes as shawn in Figures 4 and 5, wifl directly affect aU left tuming volunaes whether they be near side +ar far side. GeneraEtty, during the ANI peak hour, the eastbvund left tum will apeerdte gvarly, due to conflicting gaP piacement frvm the nvrthhnund Graffic, and conVersely in the evening the eastbound leflt wiU have to ovmpete with pps fram the soudibaund thrvugh (wvrk to home base) commuters. 'Ihis situation, will almvst always cause the eastbvund leg far both 4th and 15th tv result in paar l~vels of service. Nvt due to excessive vvlumes on tte leg of the intersectian, rathe.r due to t~e high cvmmute r+olumes either nvrth vr soutti and the absence of adequa►te gaps fvr entrance anto Sullivan. As has teen nv#ed, these int.erssctians were caunted in 7une and July, 1993 by :fPE staff, hvwever, ih additiQn tv perfvraning a physical count of these intersections, additivnal operational characteristics were observed and n!pted. Primariiy along it's length, Sullivan Road fram 5prague Awenue sauth operates with art average running speed of 32 ta 37 mffles an hvur, b~ ~ ugon the highway capacit}+ manual, far an arterial street with a posted speed limit of 35 mph, this arterial strmt wauld have an LaUS of A1B. Additional aperativnal characteristics were tibserved algng Sullivan Road, dunng the 7une and July eounting aperations. The single largest contrihuting fac#Qr tv the paor leVe1 vf servire both caiculat~ and measur~ alar~g this arterial is the lack of forced gaps ar:d platrons alvng Sulfivan Rvad south of 5prague Avenue. The term fvm.ed gaps refers ti a traffic cnntcol device such as astvg sign ar tra~ffic signal which farces gags in the tlimugh traff c stream 'and increases headvvay between vehicles. T,he vther, significant abservatiun was the lack of plataons, along Sullivan Road, vahich alsv results in staggered vehicles beatween platvans and few gaps for left tuming side strest traffic tv rnake ths intended rrtavement. ' Ohservations, clearly urdiGated that the number ~f turning Wehicles frvm the side streets were not significant as t~i their imm~iate v~lumes, but after severa1 minutes of no-gaps alvng Sullivan Mand Paexfir Engincerettg Copan3' 21 Sihrllry Lab TL! Road, they would begiri to queue ug along their respective legs. I]uring bath the AM and PM peak hvur, it was nvt unusual to Qbserve, three to seven vehicles queued up waiting to either cross vr make turns at the intersecting cross streets on Sullirraaon Road. The presence of these . vehicles, in a quewe, is primarily due ta the randarn nature of Vehicle gaps and speeds alang Sullivan Raad. Amore in depth analysis, ~vealed that during the AM r.ommute, the northbvund upsuvam vehicles, svuth of 16th Awenue, routd enter antv 5u].Livan relatively easily and at will. However, as these vehucles began their r,ommute, they wfluldbejvined with additivnal Vehicles, at apgroximate 50 to 150 foot headways. This type of headway, is usually associat.ed with a relatively gaod arterial L(3S, wtuch was vbserved to be betuveen LOS A and IAS B. However, tzis type of free flvw, daes nvt aDow the additianal side strset trafFc north of 16th Aaenue the opporturuty ta enter tne traffic stream. Conversely, during the P1VI peak taour the svuthbvund traffic which is a11owe3 ta enter 5ullivan thmugh the Sullirran and Sprague signali.red intersectian, do so in a rather dense platovn. However, given that there are nv traf~ic cantrol devices alvng this mute (stop signs ar signals) the araf~ic is allawed ta rreach a free flaw speed with increased headway. I]uring the PM geak hvur, dhe only gaps created in the traffic stream are when a sau#hbaund Vehicie tums left, eastbound, thereby slvwing dvwn fallvwiiag Sullivan Road traffic unti1 the mvwement can 6e made. However, due to the width of SuUivan betrWeen 16th and 40th Avenues, this situation can reafly vnly occur at those intersectians svuth of 16th Avenue. In the event that_ gaps were available, the queue of two to seven vehicles could be released by a gap as small as 10 ta 12 sscavnds. There, aze several excellent resourees far gap pmgressivn, ' but for this analysis we har+e used +ureeri,rhield's, Queue Discharge Dara wI1ich states that a gap ~ of 8 to 12 seconds will accommodate between 4 and 5 cars in ttde que►ae, which is the upper limit of the aVerage number of cars experiencetl in any ane left turn queue. ThereFare, based upon ac1ual gap timing and field mbservatians, ihe operation of the unsignalized intersections a1ong Sullir~an Rvad, with an Lt)5 of E, with the additian of gaps cauTd maintain better levels of service than indicated iri the LOS calculations as vutlined in the HCPVi. A,s the highway rapacity manual dves nvt deal well with gap relationships in trawel pattems and dcres not have the abiility _ tv analyze adec;,uately this juxtaposition in pattems. Warnznt Analy+ssi.sr Althvugh no actual wazrant analysis was perFormed, the Sullivan Raad and 4th Avenue intersection by inspection NIAY warrant a traffic signal due ta meeting the criteria for Warrant Nv. 11, Feak Hvur Warrant, as outlined by the Manual on Z7ni, form Ttgffic eontror peWces (MUrrcD). lnleznd Paqfic Engineerin8 Gwwny 22 Shelley Lake 71,5 ~c Sqfety pa Aceidenc summaries available fflr the nravst recent three years (12101J89 ta 12131192) fram WSDOT and the Spokane Caunty iles for the identified intersectivns within the She11ey Lalce Vicinity were asserniblec.

The resulting estimated trip distribution is shown in Figure 6. The resulting trip assignment W the existing transportation system is as shown for Alternative No. 1 in Figures 7 and 8 for Alternative No. 2 in Figures 9 and 10. As shown in Figure 6, 62-percent of the site generated trips have been determined to be from/to the north. This corresponds with those trip distribution rates as provided by the Spokane ~ Regional Council, employment data model. This data from the SRC provides employment and non-employment areas. These areas then determine the destination of the morning home-based to work and evening work to home-based trips. The actual trip distribution when run on the SRC model incorporates, land use, street type (classification), size (number of lanes), speed (posted) and several other social and economic aspects of the overall area. From this model, then an existing or proposed trip can be modeled to determine the actual, or nearly actual path that the vehicle and it's occupants would chose to access the appropriate land uses. The critical factor for this analysis is speed and progression, the computer opdmized these two factors to determine what will be the least time dependent route and then adds the commuting vehicle to that route. BAC%GROUND TRAFFIC Due to the growth which has taken place within the Greater Spokane area, growth rates for the area south of this project vicinity were obtained from both Spokane County and SRC. The input from the County indicated that the general northbound and southbound through volumes along Sullivan Road should be increased by 3.0 percent per year, for the twenty year period analyzed 'i Inland Pad,fic Engineering Compa►y 29 Shdlry I.ake TIA ~ . . ~ (1993 through 2015). This increase'in through traffic volumes would approximate the existing growth rate which is expected to continue throughout the duration of this project. For those arterials, oollectors and local roads adjacent to or intersecting with, including Sprague Avenue, a 3.0 percent per year growth rate was used. As with the growth rate associated with Sullivan Road, this rate will be applied to alil area streets over the twenty year period analyzed (1993 through 2415). This increase in ttaffic volumes along these streets, as with Sullivan Road, is expected to continue throughout the duration of this project.

This intersection reduces from and LOS of I3, with an average delay aF 36.0 secQnds to an LOS of DIE with an aVerage delay of 41„6 seconds. Atthvugh the LOS D leve1 as exceeded, an increase of 5.6 seconds of total delay, is sQmewhat arbitrary due ta the somewhat subjeective nature of signalized intersectivn level of service calculativns. Usually, the nde of Lhumh would state, that vvith mvre aggressir+e signal timing, by incorparating shvrter cycle lengths, incvrpQrating more right tuan an red vr leR tum permittedlFrotected phasing a 10 tv 25 perc;ent reductivn in delay can 1e achieveri, In vrder tn maintain cantinuity between level of serwice calculations for review, these timing aevisivns were not inrorrpsvrated. T'herefvre, an average delay change fronn 36 W 41.6 seconds cuuld be oansidered to te very little change, if any at all. Addiiianafly, the primary reason far the incr-ease in LOS is due to the overall increase an tra,fFic vvlumes at chis intersection and the reductiva in green time for the eastbound and westbound directions given the larger thraugh volu:nes along Suilivan Avenue. 'Iberefare, if there were more tk►r+ough lanes available for through traffic progression vr avrthbound left tums the overall ~ intersection level of service could be maintained within the acceptable limits of na less than an I..gS of D.

As with the earlier discuss'rons, 'the levels of service reductions on Sgrague Avenue are not reiuctions fln Sprague Aaenue, rather they are the resulc of additional ihrough vvlumes on - 5prague Avenue and this fihrough traffics irnpact vn the intersecding side streets, 'ne impact to the intersecting side sMeets is usually in either the northbvund ar southbound unsignalized left turn. As indicated for Phase 1completion, the incre.ase in bvth through traffic um Spra,gue and an increase of 15 left tums reduced the resen+e c:apacity hy 150 Vehicles. 'Y'he same is true far ~ the Phase 2 completian, vfrhere the iricrease in northbound left turns from a pre-develnped altemative valume of 4 is ta a developed buildout volursie of 68 Ieft turns. Tt shvuld be nated that this valume is approximately half that of the left turns in tlae AM peakk hvur. However, the higher eastbound rommuting volumesvn Sprague and the +canflict that they present, fvrces this intersection ta an LOS of F. At the 5ullivan Road and Sprague Averrue intersactivn, the reducgan iri ler+el of service created by this intersection is twa f4Pd. First, the incream in thraugh vvlu,mes due ta considerable backgrvund gmwth, combined with an increase in left turn ►►alurnes for access ta the propased Fred Meyer facility, have pushed thas intersectian beyond it's capacity to serve the expeccted grvwth.

ALTERrvA77VE Na r Phase 2 - aoao AM Petrk Haur -Based upon the analysis as perfarmed far this altemative of the prvpcr5ed ShelTey T.ake development for the future year buildout of 2000, several intersectivns drvp belaw the backgrQUna levels of service, while vne of these irstersections drog below the ninimum threshald as outlined by Spokane Gounry, Uuring the AM peak hvur, the two interswtions which drap belvw the baclc,gmund leVels of service are the Sullivan and 5prague and the 5prague and C:vnklin intersectians. The Sullir+an and Sprague irttersecdon, hower+er, falls be1Qw the minimum acceptable level of service f4r this intersectian. As described earlier, the change in LAS is from an IAS of m(36.d seconds) ta and TA5 of E(41.6 seconds). Althvugh, the change cazries the intersection thraugh the Ld5 of D1E threshold, several tirning revisions evuld be incvrptarated to mirumize or negate the ~ impacts. 'I't4e real measure of this signalazed intersections capatailities tv handle the added traffic vglumes frorn this alternatiwe is that the Vlc ratio maves fram a t3ackground Vfc rativ of 0.78 to a with the alternatiae Wc Tativn of 0.89. Therefare, this intersectifln maintains adequabe capaciEy to handie the vvlumes generat,ed by thiis prvpvsed project as weU as the background growth, but the signal timing and existing lane configuratians do nvt atlaw the intersectian to operate at it's maximum potential. PM Perrk Haur -Based upun the analysis as performed for this alternative of the prapnsed SheUey Iake deve.lopment, for the future year buildnut of 2000, only vne intersectinn draps belaw the background levels of ser►►ice. This intersectian is the 5prague and Canklin intersection, arid in addition tv drapping belvva the background level of servir,e, it alsv drops below Spvkane Caunty's minimum acceptah1e level of serrrioe. For an unsignalized i.ntersection the minimum acceptable level of service is an LOS of E. At this locatican tfie resulting 1eve10f service far this altemative is an L.QS of F, with a wwrve capacity of -35. A5 I1C1ted ea1118ti this is dwe to the increase of 64 additional northbound to wes#baund 1eft tums frvm Conkiin onto Sprague. It shauld be nvted #hat a reductian in intersectian reserve capacity is being reduced by four times the number of added left turns. This type vF capacity redruction is indicative of increased through traf'fic vvlumes on the irstersecting street, in this case Sprague Avenue. 1nland Parsr,r'fi~c Engineering ConvA+y 59 Shetlry Lake M ALTERNATIVE N4. 2 Phose I -1995 Based vpon the analysis performed for xhis alternative fvr the proposed Shelley Lake development, no direct specific impact, which would degrade the Phase i, 1995, background leael of service of the surrounding street system can be detezmined. The only significant change is nat in leueT of service, rather concems ihe degree of irnpact. As shown in Table 10, the AM peak hvur reserve capacity of the Sullivan and 4th intersection, decreases frvm-an LL}S of F 2 1) to a.t3 LOS of F(-fl43). What this signifies is that, due w increases of through traffiic volumes alang Sullivan Itoad any inczease in traffic to t.he adjaoeat side stwts will noticeably reduce the a►ailarble gaps tv greater de,gree than the spedfic number of cars added. Ax+ example of this was discussed fvr Alternative No. 1, where 64 left turns were introduced and the reserve eapacixy was reduced by a 4: 1 rativ. During the PM peak hour this sa.me int,ersectivn decrease.s frorn a bacIcgrvund LC3S of E (-146) W an LC]S of E (-188), the reasoning for this is the s,arne as desccribed far the A►M peak hvur.

'Me 1985 Highway Capacity Manual includes a method for calculating the LQS at vneltwv way stap-contrvlled intersections. For these unsignaized intersectians, ZAS is defLned differently than for sign,alized intersections in that it is based upon the concept of "Ttesen►e Capacity" (i.e., that portion of available hvurly capacity that is nvt used.) LC)5 in the context fvr an unsignalized intersection is based upnn the idea of "Reserve C.apacitY," which represents that hvurly portavn of the intersactinn's aVailable capacity which is ttnused. Fvr unsignalizeti intersections, this is based upan pcftentially available gaps in the conflicting traffic stream that are avaRable to make a specific turning ancrvement. An ex,ample is that an eastbvund left turning vehicle must yield ta both nvrthbvund and svuthbound through and left turning vehicles. If #here are not very many nvrth and southbvund vehicles, then the eastbaund left mming vehicle wi11 haae more appariunities (gaps in the traffic stream) with which tv make the tur,ning mvr+ement. Howeverr, as trWtc Volume.s nvrth arid southbuund increase, there are fewer and fewer opportunities in vvhich the westbound left can be made.

REASON►46LE ALTERN►4TIVES Twv afternatives to the prvposed activn tv rezvne and develop 5helley Lake have also been analyzed. They inelude 1) De►relvpment 1Jndee Existing Zoning, and 2) a IVo- Actian alternative. aevelopnnent llnder €xisting Zaning Alternative This alternative would sfivw the site #o be segregated into 10,000 square fvot parcels far areas zoned L1R-3.5 and vne acre parcels for the 20 acres zaned SR-1 . The prapased rezone to UR-1 2 and PL10 over'ray for the entire site would nat occur. This would allaw the deVelopment of 225 buildable parcels, slightly less than half the 459 units propQSed. Under this acternative raad'vvay cannectinns courd caCCUr at Shamrvck and Galway Streets, Retch#mrd Drive, and 4th Avenue, increasing traffic cvunts on all of these raads. AII raadways would be developed tv public standards. There would he fess demand for puhlic serVices than for the prppased action alternative due to fewer residents being intrvduCed inta i'he area. Fewer peo,ple would result in less traffic, schavl childsen, and lawer amoun#s of imperviaus surfaces. Without the PU D averlay there would be less area designated as apen space. affording less pratection to sensyti►►e features and habitat areas. No enhancemeunt of wildlafe habitat areas would occur and there would be no additianal restrictiQns an their use. A homeawner's assvciatic,n would nat likely be formed, efimina#ing the restrictive covenants prQposed cvntrolling aesthetic and wildiife impacts. N❑ educatianal ar - recreatianal apportunitues would be provided. Nv-Activn Alternatiue This alternatiae would totally preclude any develvpment af the project site. Existing cvnditivns would remain an-gving. The positive ienpacts an wildlife habitat areas discussed as part vf the Prvposed Actian would not accur.

NaruRAL ENViRvNMENT 1.4 rntater , - Sheiley Lake's fairiy steep sides, gravelly soil types, limited visibifity, and high degree af vr►ater level fluctuatians have all contributed to its lack of aquatic ve9etativn. The current water quai+ty has been degraded by up-s#rearn and possibly an-site agricuitural ~ practices. Fertilizers and pesticides haVe artificially increased nitragen and phosphorus IeVels. Peat mining operativns fn the SaItese Flats have added substantially to vrganic particulate matter inflow, which when decamposed depleres dissolved oxygen supplies. ►4naerobic conditions have !ed to fish kills, zeduced visibility, and odvrs. The addition a# irr►perivus surfaces wiia change the directivn and speed of an-s'rt€ surface water. ff not managed properly the rernoval of undesirable vegetatian and disruptivn of sail could add to the amvunt ot contaminants and sedinaent rsaching the lake. Vegetative buffers and reten#ivn ponds wi!l slow vr cvntain excessive run-off, preventing it frvm reaching the lake. Design param+aters establisla setbacks that p'lace developed portians af the site at least 50 feet or more upsiape fram the lake's shvrefine area. Large animal-keeping will nvt be allowed. Prvfessivnal water quality sampling will be completed privr to initiating future pptential lake mana$ement techniques, if prapassd by the hameowner's associativn, which may include: SheJley Leke Draft 4 February 1994 ~ •red LECIng ClpStrBa1'T1S[7u6C@5 aIidIoF BCCUR1lllatIQn of ~orgafIIC partIGUIB~e mStter. • increasing dissalved oxygen content thrvugh aeratian or artificial circulation. • maintaining a stahle water level through increased surface fIow or pumping from an existing well. An erasion cantrol plan and a stvrm water managerr~en# plan will be cqmpleted privr to final platting. The 1 a0-year flvod plain elevativn of 2027 established far 5aitese Creek at the Steen Raad bridge has been prQpased and accepted by the Spvkane Caunty Engirreers. The existing oVerflow to the gravel pit nor#heast of the site will - continue to provide a margin of safety fvr cvntralling flaodwaters. The drainage channel and graVel pit will be secured far future oVerflnw control as required by the County Engineers. 7'he four Iats that have land bskvw elevativn 2028 will he required to obtain flood pfain develnprraent petmits. 2. Plants and Animals 5ite deveiopment will likely encroach upnn existing natural habita# areas used hy • waldlife. The PUD design alfaws for prmvision of apen space to protect sen5itive habitat areas. Restric#ing domes#ic pets, IiVestack keeping, and herbicidel pesticid+el fer#ilizer use will eeduce their iTnpact on wildlrfe habitat areas. Most af the undesirable knapweed will he efiminated. 5horeline areas on either side ❑t the soft pedestrian trail will be enhanced by plantirrg vf vegetation with high value to wildlite. New trees, shrubs, and grasses will 4e introduced to the siCe fflr food, cover, and nesting. Minimum landscaping standards will be established an the restrictive cvvenants. These will stipulate the type af Iandscaping permitted in the transifinn zone between native and culti►►ated plantings fvr lats along the lake's shoreline. Educatianal materials cancerning habitat enhancement efforts will de prvvided to site residents. 13UILT EN111RDNMENT 1.0 Land arrd ShareEine Use The existing agricul#ural and' rural land use charaCter af the site would be altered due to the introduction vf urban densities and public services. The prvposed actian prvvides a density transitivn between tFre hsgher density manufactured homes and raiulti-family units to the narth and the lower density large acreage lvts to the 5cauth vf the site. Project design includes a 50 fovt set'hacic of lots from the lake's ocdinary high water ele►vatinn, pravid'ing approximately 100 feet af separatian between the lake and housing structures. Therefore some of the hvmes will be within the designated 200 fv❑t shoreline area, requiring a Shoreline Substantial Qerrelmpment Permid. Construction af a vrrvoden bridge for crassing the soft pedestrian trail over Saltese Shelley Leke araft 5 Fe6ruery 1994 Creek arnd the trail itself vvill alsor require this permit. ►4 futurs Gommvnity dock and develvpment vf a aeach area would alsv require this permit if prvpased by the hvrrieawner's association. The project vvifl comply with all the palicie5 and requirements of the 5horeline Mastes Program. Tlne majarity af the site is zvned UR-3,5, vvi#h appraximately 20 acres_TVned SR-'I. A zone change tv 1JR-1Z for 14 acres currently zoned UR-3.5 is prvpvsed, with a PU D overlay fvr the entire project site. 6onus densityr would appiy ta the UR-9 2 and SR-7 zones. The zone change tv UR-1 2 wauld afl'aw develapment af multi-family units on the narthwest corrrer of the site. Banus Rensity Paints haVe been earned by designing the PUD to make special provisians fvr common vpen space, enviro nmQntal cancerns, pvblic sen►ice a nd fac ility auailability, using a design team, arrd providing a rr3ix of hausing types. With the praposed zvning and PUD averlay with banus density, the allowable number vf lats cAuld cvnGeivably be 672, al#hough only 459 are proposed. f'f propvsed under existing zoning with n❑ PUD averlay or hvnus density, only 385 Ivts would be aIlQwed. The existing and proposed iones are cansistent with the Urban and Suburban(+) categvries of the County's Gamprehensive Land Use Pian. R'estrictive cnvenan#s will cvntrol the aesthetic appearance vf home5 and v+uill ensure a safe enjvyable living environment. A phasing schedule anticipates arr eight-tv terr- year build vut, with approximately 50 ivts devetaped per year. A protessivnal archaeolagical survey was campleted fior the praject site and included a recards search and field survey. N❑ sFgnificant cultural resources were four+d and therefvre nQ impacts are expected to occur. Should a patential cultural resource be discvaered, on-site canstructivn will halt until a prafessional evaluatian of the resource ~ can be campleted. 2.0 Transportetion Several new County roads are propased ta be develaped within the project site. The vnly connection tv the svuthern street termini will be via Rotchford Drive, which will be extended intv the plat ta tie directly intv Canklin Raad. The intersection of 4th . Avenue and Conklin Road wilf be recons#ructed so that 4th Avenue will make a curve tp the svutheast and tie into Conklin Raad at a 90-degree angle. Primary ingress and egress wilf be via Caraklin RQad narth]south tv 5prague avenue. Amendment af the Cvunty Rrterial RQad Plan ta allow an intersection at Cvnklin Road with the Svuth Vafley Arterial will be pursued. Na through connection wilf be proWided by this prvjsct to Steen RQad. AlI rvads will be paved and developed tv Caunty Engineers standards. Rotchford Orive vuPill be the araly pub:ec roaa witnin rne piat. 7he majvrity af the roads will be constructed ta priVate PUD road standards. The plat will be develvped in phases, with 58 units completed by 1995 (Phase 1) and the remaining 407 units campleted by 2000 (Phase 2). A traffic analysis was She►'Iey Leke Urefr 6 Februery 1994 . prepared to addre5s traffic generatian, levels of service, arad the need fvr imprQUements to mitigate impacts. At #ull build nut there would be a projected 3,750 vpd, with appraximatety 283 ►4M peak hour trips and 375 PM peak haur trips. The ; largest peak hour generated traffic occurs in the PM when 246 Vpd will be entering ihe s+te. Fhe fvllowing canclusions are documented w+thira the Traffic Analysis included in Appendix E. + 6y 1995 with present background ►►v1umes all study area intersectians will operate within acceptable levels of serwice; 5ullivan and Sprague (Lt'3S SulFiaarr and 4tIn (LOS E), Sprague and Conklin (LOS C), and Sullivan and 1 fith (L[}5 E). Althvugh these intersectians are currently vn the margins, there is capacity far additianal westbvund and northbaund movemenis. • 5hauld the averall deVelapment and grvwth of the area be maintained at nearly 3.0 percent, two of these intersectians are expected ta fail prior t❑ deVelopment of tFris project; Su'liidsn and 4th (L05 F) and Sullivan and 16th (LO5 F). Zh+s is due tn westhaund to nvrthbaund lefts and higher thrvugh VolUm@5. • After the cvmpletivn of Phase 1, ahl study intersectinns are expected tm remain at the same background IeVel of service as prajected. This does nvt nnean that this deVelopment will nvt add additivnal aehicles tv t'he transpvrtat&an system, oniy that the intersectians for 1995 Faaue the LDS capacity fnr the increase in backgraund traffic and the development of Phase 1. ■ With the campletivn of full tauild out of Fhase 2 by 2004, several intersections will need imprvvements tfl allow ihe vvlume of anticipatsd traffEC ta pass at reasonahle levels of sen►ice. Sullivan and $prague, due to the design of the pfat directing trips to Sprague via Conklin during the PM peak hour (by adding Sd - 90 left tums from #his project, added to the 1995 expected 420 existing PM peak haur left turns), wifl be pushed beyvnd its eapacity tv serVe left turns. Additivnally, the 5prague and Conklin in#ersectivn during the RM peak hour will drQp to an LOS of EIF, ►rvith LOS E being the minimum standard for an unsignaiized intersection. AIthvugh the addition of 58 single-family homes in Phase 1 and associated traffic will cantrihute to the existing trafific currently using the Sullivan R❑ad and Sprag ue AVenue cocridors, the vnly impact will be that ta►nrards the cumulatiVe average daily traffi+c valumes. The prvposed development will not Faave any significant impact to leuels of service thrvugh the develapment of Phase 1: Spokane County has identified Is►►el ❑f service a5 the indicator far prablems associated wi#h deVelapment and, th+erefiare, based salely on LOS this prgject will have rra ampact. Ha►nrever, su'bsequent develvpment of this plat ira conjunction with develnpment in arrd araund this area w+ill require the improvement of several streets and roads within this general area of Spvkane County. At the request ❑f the Spakane Transrt Authority, a future transit Shelley Lake Dreft 7 February 1994 ! stap and shel'ter area has also be6ro reserved, 7his area is facated on the sauth s'rde of 4th Avenue, adjacent to the pr6posed rraulti-famiCy area, jvst west of Carrnery Raad. At the campletian of Rhase 2 a traffic signal vnay he warranded at the intersection of 5prague ►4Venue and Canklin :Rvad. This signal wvuld be raecessitsted ay a co mbinatian of iactors including t;he continued a rea deve[opcnent and growth exclusive of the Shelley Lake prvject and the additivn of the Shelley Lake VQlumes. Hawever, this signal shaufd he installed ►tvl~en this intsrsection meets at least faur warrants for signalizativn, as outlined in the Ma nuaf o# LJnifiorm Traffic GontroE Devices (M UTGD), In addition Cankfin Road from1 4th AVenue rrorth tv Sprague ►qVenue wiLl be constructed to Spokane County bvllectvr arterlal standards which include a4[3-fnvt rvadway sectivn with cur4s, gut~+ers, arad sidevwialk5. Due to the nunnber of pro,pvsed developments along the Sullivan Road cvrridor, it is uncleac r►dhether develapmerat of the prvpased action would require the impravements recvmmended due to developmdnt of this praject aEvne. WitFm tFae other propo5ed deVeIoprarYents a1Qng the Sullivan rpad carridor, these improvements are recvmmended and required in svnne instances ta aIlvw thrrvugh traffic prpgression. Hawever eVen with the develvpment of the Su€tfuan Road cvrridor, the develppment of Qhase 1 can he rmplemented withvut having adsignificant 'rmpact vn the overall area transportation sysCern. 3.0 Public Services An additianaB 459 residences will be added to the respansibility of District No. 5 of the Cvunty 5heriff's Departrnerrt. The added papulatian vvill increase the number of pevple requiring servace and the number of crimes committed. Prvject design makes Rotchfard Driae a cD1iector arteria1, which places homes alcang Rotchford in the 19% patential erime rate catsgary with ian cncrease frvm the currently existing rate of 15 The rate at these hvmes wvuld be equaE tv the averall average. Hvweyer the ,private cammunity type of design propos!ed, which includes only twn access pairats into the develaprnerrt and perimeter fencing, typicafly generates Iess ca11s for sen►ice than the grid type of street design. The develvpment wilf nat be gated. Many of the upper- incame hvmes wiil have resauriftes do instafl individual security systems. The fvrmatian of BIvck Watches will be encvuraged. Approximately 274 schvnl chil'dren are projected at full build vut of 459 residences. The increase will be gradual based an an eight-to ten-year develvprraent with approximately 30 new studsnts per year. Adams Elementary and Greenacres Juniar High are nearing capacity and willlbe irnpacted by the addition of new students frarn this and vther residentia3 deVelvp { ents. There is adequate capacity at Central Valley High. HvweVer Schovl District No. 356 needs tv cornplete their existing exparasion plans and requests that #he developer negntFate a vo Iuntary agrsement tv help mitigate the praposal's impact on public schvals, The new res+dences will increase the demarrd for park space and facilities, with most 5helley Lake 1]reft 8 February 1994 of the impact occurring vn vrganized Sports faCilities. Deve8vpment af the 5ite wi[l preclude 5helley L_ake's acquisition by the County Parks Departmsnt as recammended - in their 1989 Plan. Recreatiarral opportunities will be provided by the praject, including a soft pedestrian taail surraunding the lake. Areas are designated for the future developmen# vf picnic, beach, dock, and community center facilities if pr4pnsed by the hvmevwner's assnciatiorr. On-site activities may include walking, jogging, cross-country skiing, birdlwirdlife obserVatiion, fishing, swirnm+ng, ice skating, and rv►rving and' canaeing. The develuper will be required to sign a document agreeing tv future mitigation measure5 imposed by the Board af Caunty Gvmmissivners that help alleviate impacds to the CQunty Park system. ►An additional 459 residences will be gradually added'tv the resppnsibility of Spokane County Fire Prvtectton District Na. 1 vver an eig'rit-to ten-year build vut period. This may result in an increased need for additivnal manpawer and equipment in the area. ~ Fire hydrants wie2 be lacated thrqughout the prvject site and supplied by adequate f`rce flows.

Shelley Leke Draft 9 February 1994 PROPOSED ACl I OI y AND ~L TERN.a TrVES I! PROPOS~D ACTfC)►N The prnposed action includes a prefiminary plat with a planned unit deve9opment tPUDy overlay zane nn apprQximately 123.8 acres. This praposed action would allow the develvpme nt of 459 new resid erutial dwell6ng u nits and prvvide substa ntial o p e n space areas thrvugh the praVision of clustered lots. The project site Gontains sensitive aceas such as Shelley Lake and its associated wetlands, slaped areas, and witdlife habitat. Qeveiapment of the project site by utilizing a pUD concept can prvtect, manage, and . enhance these sensitive areas. _ The prvject site is Iocated in the 5pvkane Valley, approximately 1,300 feet east of Sullivan Road and appraximately 600 feet svuth of Sprague ►a►venue (see Figure 1). The site lies nvrth of the Fiotchfvrd ACre Tracts Subdivisian and coimpleteEy surrounds Shelley Lake in Section 24, Tvwnship 25 North, Range 44 East, W.M. (see Figure 2). A rezane to Urban Residential-9 2 (UR-12) with bonus density is proposed for 14,0 acres on the west side of ths site t4 allow for the develapment of 195 multi-family units (see Figures 3A and 38). Single-family residential lots will include a mixture of housing typss including 68 manufactured homes on platted Io#s in the nvrtherrr area of the site, 158 canVentiQnal homes an sma#I Ivts arvund Shelley Lake, and 38 large kots an the sate's southern portion. 7`he pTOpvnent's objeCtive is to create a fairly private residential cvmmunity an asite that is currently undeVelvped, with a variety of paTcel sizes ranging from approximateRy 6,000 square feet to 41 ,000 square feet, and approximate9y 37.9 acres of vpen space. The vverall site density prvpvsed is 3.7 units per acre. Praposed densities per zoning classi#icatian are as follaws: UR-3.5 at 2.30 lots per acre, 5'R-1 at 2.09 lots per acre; and WR-12 at 13.93 units per acre. 7he minimum lot size for the vR-3.5 zvne v+tith aPt10 overlay is 6,000 square feet, with an overa!l maxirnum density of 3.5 dwelling uni#s per acre. 11Vithin the SR-1 zone the minimum lot size is 15,000 square feet with a PLID overlay, pravided the aVeratE density does nvt exceed ane dwelsing unit per acre. The minimum IQt size fvr the UR- 12 zane with a PUD averlay is 800 square feet, with an oVeral1 maximum density of 12 dwelling units per acre. These maximum densitiss can be exceeded thrvugh application of bvraus density provisions. A total at 1.95 unit5 per acre of bvnus density can be earned with the prvpased PUD design and applies tv each zone classification. This results in a totaf of 672 units alkavved for develnpment, alth❑ugh anly 459 are being prvposed far full deVelapment of the pTaject site. Fuil build-out of #he proppsed develapment is expected tv take place aver an eight to ten-year periad, depending vn housing market conditions.

The prvposed preliminary PUD plat has been designed in an effvrt tv keep environmental impacts to a minimum. Environmentally sensitive site design and 5helley Lake l7reft EIS 10 Fe6ruary 1994 enginearing includes prvviding #o r a minimum 50 foot vpe n spacelb uffer area be#ween the lots and the lake's ardinary high water ieuel, and retsining 37.9 acres of the natural vegeta#ian, wildlife habitat areas, and slopes in apen space. pn erosinn control and grad4ng plan will be prepared and implsmented priar to site constructinn, and may inciude techniques sucFa as straw bales and netting fa protect slvpes and associated sur#ace water dueang construction. ►4 master stvrm water rnanagerr+ent plan out[irring ~ediment basins and retentinn ponds will include identi#icativn of methads and maintenance fvr stvrm water drainage cmntral. The site has been designed sa that the lowest flavr af homes wail be Iracated at least twv feet abnve the lake's 1 04-year flood elevation of 2,027 feet, in accordance with the County's Flood ' Plain Ordinance. Deuelnpment of the project site vuill encraach upvn established wildlife habitats and migratory rvutes. The 37.3 acres, of opera space is designed ta preserve mvst of the site's natural vsgetation, provide substantial buffer zarres around wetEand areas, and ranainta`n existing wi1dl'sfe habitats. Ths open space areas will be pcotected and restricted from #u'kure developmen't. Methads to en'hance the existing wildlife ha'bitat areas wi43 include planting vegetation of high value to wildlife along the shvreline, - remavirag a substantial amount of intraduced weed species, and proWiding educational Gnaterials t❑ residents cvncerning wildlife enhancement prvgrams. Deaelvpment of ihe praject site wil Y impact the existing external transportatian system within dhe Vicinity of the site by adding papulatian to a preVivusly uninhabited site whrch will generate traffic. This prapvsal creates new roads within the site to access the lots and pro►►ide ingress and 4,gress from the site.

ENVIRQNMENTAL INIRACT STATEMENT 11. REAS'ON.4BLE AL TEA'N.4 TlVES Twa alternatives ta the prapased activn to reaone and dEVelop Shelley Lake a~re als❑ given considera#ian. They include: 1}❑evelopment Llnder Existing Zoning, and 2) a Nv-Action alternatiVe. The faklvwirrg is a general discussivn vf im,pacts regarding - these twa alternatives. 1.0 DEI►►ELOF'MENT UNDER E]K15TiNG Z[}IVING !f the project site was aIlowed to develop under the existing zaning, the propvsed rezone ta L3R-12 (U rban Residential-12) and PUa ayerlay for the site would nat occ ur. The sste vvou9d remain zoned UR-3.5 (Urban Reside ntial-3,5} and SR-1 (Suburban Residential-1 This would allaw the site tfl be Segregated +ntv 10,000 square fovt minimum parcels fvr areas avned UR-3.5 and vne acre minimum parcels far the 20 acres zvned 5R-1. Maximum densities fvr #hese areas are three arad ane-half dwelling units per acre (UR-3.5) and one dwelling unit per acre (SR-1). A conceptual fayaut plan fvr develvpment under existing zoning using these densities is presented as Figure 4. This alternative would allaw the develvpment of 225 buildable parcels an the site, slightiy less than half af the 459 units proposed. This Eawer density wauld most likely result in kower quantities vf impervious surfaces than that pro,posed, due to the devel❑pment of fewer housing structures. Hvweuer this alternatiue wauld be develvped wi#h all pubiic raads, which are wider than the mnstly priVate roads included in the Propased Actinn alternative. If there are Ivrruer quantities of imperVinus surfaces, then less stvrm vaater run-off vvould be generated by this alternative. IHvwever a master cavrdinated starm water management plan for the entire develvpable area may nat be prepared ar implemented. This type vf plan wiEi ensure ihat storm water run4nff and cvrataminants do nat discharge to the lake from surraunding urban areas. If the property were ta be subdivided, the applicable standard fram the Gaunty's Shvreline Program is a200-foot structural setbsck unCess a Substantiaf Development F'ermit is obtained. If the land were tv t e segregated via exemption from the su4divisian regulativns RCW 58.17, then only a50-foot setback from the vrdinary high wat+er mark would 4e applicable. Development under exist+ng zaning cauMd include roadway cannectians at the existing terrnirai at Sharnrock and Galway Streets, Rotchford Drive, and 4th AVenue. This would increase traffic counts on these rvads and impact a greater number af residents in the adjacent Rotchfvrd Acee Tracts to the south. Fiowever these roadway cvnnections wvuld tend to disperse traffic throughaut the residential area rat'her than cvncentrating trafific an Rotchford arive. Also less tvtai trips per day wvuld be genera#ed from the si#e with onEy 225 residences instead of the prvpased 459. A11 roads w+rould be developed to public rathec than mastly priVate rvadway standards. Shelley Lake ❑reft EIS 18 Fehruary 1994 There would be less demand far public serVices in this area due to the decreased number af dweiiing units and associated pQpulation. With sparser deVelflpment, the schvnls serVing the site would have less demand pfaced Qn them for educatyanaf serVices. Hvwever the schvol district would still need ta provide bus service tfl this area to ac+cvmmadate the relatively few children needing trarrsportation tn and #rom schoal. There would alsa be less demand for police and fire fighting services due to the lower populatian levels. The increased number af transportativn access paints would decrease respvnse times tv the site. Lvwer populativn fe►vels than those prQpvsed with the zane change and PUD overlay would at first appear to resuft in Iess disturbanCe tv wildlife and hahitat areas. FiaweWer withaut the provisians af a PUD vVerlay avne, there would be less area designated as apen space, affording less qratectian ta sensitive habitat areas. Ira add'ition th+ere rnay be few provisions regarding future develapment of these areas and nv site specific restrictive cvvenants to ~overn their use. A well coardinated plan for weed cantrfll a4ong the lake's sFaorelins may not be implemented. A wildlife habitat enhancement prograrn would not be develpped and there would nat be any cvvrdiraated ef#art ta improVe the water quatity or stabilize wa#er quantities within Shelley Lake. The develapment under existing zoning alternative may crat include the farmatian of a harneawner's assoeiation or rtestrictiVe cavenants. Thrs would aesthetically impact the area hy nat gaverning paint and fence calors, types, and lacativns. There would be nv perimeter fencing or herms with landscaping creatin$ a priVate comtnunity feeiing and increasing security. There may be nv covenants guiding larrdscaping practices with wildlife habitat needs in mirad vr preVenting disruptivn by domesdic aninnals. Large anrmaf-keeping could also be a1lowed because it is permitted within the - SR-1 zvne. There would be no coordinated educational pragram targeting area residents concerning the site's serasitive environments. Recreational vpp4rtunities would be limited with this alternative. Na trail sysiem, community center, swimming beach, or picnic area would be proVided. The d7versity in !hausing vppQrtunities would he lost with imp3emen#atian vf this aIternatiVe, 2.0 fVO-►A,CTIOMN ALTERIII~1471VE The No-Actian Alternative would totalfy prec€ude any develn,pment af tihe project scte. Existing cnnditians would essentially remain vn-gving, including current agricultural productivn. There would nat be any impact to public services if the praperty did not deVelap. Addstianal schanl capacity, busing, and fire and pvlice protection services would not be required. Utility and rosdway extensivns onta and throughaut the site vuvu1d nat occur. There woufd be nn increase in vff-site traffic generat+ed by deVelopment of the site. The rack of fire hydrants would result in less vvater available at the si#e fvr fire fighting ,purpvses. 5helley Lake Draft €15 19 February 19$4 I~ 7here would be no additional imper►►ivus surfaces added ta the site, 5torm water run- o#f generativn would remain unchanged, hvwever existing impacts to Shelley Lake that may be caused by agricultural product run-aff (i,e. pesticides, herbicides) would continue. Yhe pasitive impacts on wildlife and wildlife habitats autlined as part af the Prvpnsed Activn would nnt occ ur. 7he lake woutd cantinue its wide water IeVes fluctuatians arad would prabably corrtinue to be severely impacted by suspected upstream land use activities. No caordinated effort wvuld take place tv rananage the existing water qua1ity and quantity af 5helley Lake, which wauld substantially rmprvus its fishery resourGes, vegetative and wildlife species divarsity, recreation pntential and aesthetic appeal, as vvell as imprave the waters for aquifer recharge. However, the lack vf peo,ple wauld remave any pvtentia6 for encroachment an existing wildli#e and vegetatiVe cvmmunities. The recceatianal oppvrtunities included in the Prnposed Actian alternative would nvt be provideti. Access tv the site is currently restricted by the prvperty qwners and nv permitted recreatianal opportunities take place on-site. The lack af residential develaprnent wvuld cantinue the passibifity of future purcha5e by the Spvkane Cvunty Parks Qepartment, as outlined in their future acquisition plans. Howe►rer there is a severe lack +vf funding fiar park prmperty scquisitian and additimnal funds wauld be required far prvperty maintenance arad water quality improvemen#s. If park acquisition were to occur, County improvements may well be limited campared to thase prQposed by this prvject. Hvwever, recreational vpportunities at the site wvuld be aUailable fvr use by a!1 Caunty residents. There is n❑ public benefit provided by delaying ❑r precluding residential develvpmerat af the praject site. Urban services are auailable an adjacent prvperties and the proposed prvject wvuld provide road connectians and urban seruices to the area. Additional public benefit would be provided by improving the quality vf the lake and 'providing IQng-terrn protection tv the wetlands areas. The site's sensitive habiiat areas wvuld be erahanced and maintained through the homeowners association. Shefley Leke Draft E15 20 Febre►ary 1994 X. ALTERNA TlVES CONSIl3ERED - Quring the sco,ping process and preparativn of thss environment impact statement, several alternatives regarding site road design and aecess were identified. The project sponsor rejected these alternatives because they aee nnconsistent with projeGt abjectives, as we1l as with comments recQived from neighharhvod residents and the general public during the scoping period. These alternatirres were deterrnined ta have seVeral flaws including econvmic feasihility, prablems associated with acquiring right- of-way outside the plat bounciary, difficulties in developing roads in areas with geologic and hydrolQgic canstraints, inconsis#ency with the sponsor's goal of - praViding a private residential cnmmunity, and inconsistency vvith the desires of ' adjacent residents tra prevent adddtional traffic thrvugh their neighbnrhood. The alternatives efiminated iram further analysis are descrihed in general farm belaw, irrcluding identification of the flaw or flaws. Roed "N" ExtensIon - Rvad "N" as presented during scvping would be a thrvugh extensivn of a public road ta the east property line. This road would line up with the ,parce l lines of the certif icate of exem ptivns whic'h haVe been preaivusly approwed o n property adjacent tn the east of the propose+d plai. This alternative was rejected and the sate rvad design was revised due tv the fack of any future roadvvay cennectidns t❑ the east of the prnject site. The only potential rvadway connection tv the east wvuld be a cvnnection ta 5teen Road, which is a northlsauth local access road that terminates sputh of Sprague AVenue. Que to the existing tvpvgraphic eelief of the area, extensivn of Ftoad "N" fram the eastern plat boundary to Steen wauld prvve to be difficult and expensive. Yhe Artefi3al Rvad Plan identifies intersectians at one-mile pnterwals in association with the future cvnstruGtion of the South Valley Arterial. Steen Raad is vn the dhree quarter-mcle and, in +order to be cvnsistent ►;►uith the Arterial Road Plan, iraffic wauld likely use 4th Avenue io co nnect from Steen to Flora Raad where the intersection with the Svuth Va IIey Arterial is planned. 4th Avenue Extensian - Th;s a1#emative vr►ould require extending 4th Avenue as a cvllectar arteriai straight thrvugh the plat ta the east property line, for tuture canraectivn to 5teen and Flnra Rvads. As t►vith 1ne Road "N " Extension, this a'lternative is determrned tv have several prvblems. Any sxtensivn of 4th Avenue east of the site would be expensive due tv high engineering and cvnstruction ccasts. A gravel pit exists narth of Shelley Lake and esst of the site in the path of the 4t'h Avenue afignment. Extension of 4th Avenue to the east tv connect tn Steen arid Flvra Roads wvuld likely necessitate cvnstructian of 4th Avenue arvund the nvrth side of the gravel pit. 7he grauel pit is +cQnnected ta Sa6tese Creeic by a drainage channek and acts as an emergency v►►erflvw far 5altese Creek and She9ley La&e. The drainage channel and gravel pit need to be preserved as aVerflow outlets for the #uture as required by Spokane Countj► Engineering staff. The grauef pit must be cansidered in any extension of 4th Aaenue tn the east of the plat. sherley take araft ErS 21 Febtuary 1994 i ij ~I ~ 6tfi AVBnue fxtension - T'his alternative wauld require extending a new rvad, autside plat baundasses, from Rotchford Drive west ta SuIliaan Road. 7his road rrvQUtd be alvng aproposed aiignment within praperty curren#!y +p►nmed by the Central Vailey School Qistrict. AlthaWg h xFais alternati►►e caufd praVAde a n additivnal eastlvvest access point tv Sullivari Rnad, there are se►reral promlems ~assvciated with it. The first problem is that access to this pvtential right-of-way wauld have tv be obtained from the Centra! Valley Schvvl District, as the property is awned by the District and lies vutside of the preliminary plat baundary. 5econdly, ahthaugh a new accass ta Sull4van cvuld reduce the numper of vehicles utilizing 4;th AVeraue, additional right turns frvm 6th Avenue nnt+a SuIIi►ran would reduce gaps in traffic at the 4th Avenue in#ersectivrr, further degrading the operativn vf the '4tFr Avenusl5ultivan Road intersection. Fldding additional traffic an SulliWan Road would alsa further degrade aperat'ran nf the Sullivan RoadlSprague Avenue intarsecdivn. Conklin Road Temporary Connection - This alternatiue cvnsrsts af a temporary thro uSh cannectio n to Sprague Au~er~ue via Conklin Rvad, with no direct access to the 5auth Valley Arteriaf. This aiternative is consistent with the Arterial Road Plan since Canklin Road does raat lie at #he vne-mile interaal as identdfied Fn the Rlan. During the scaping process sevecal passible alternatives were evaiuated for improvements to 'Sullivan Raad. One of these options involved utiiizing Conklin Road as a temporary refief far project #rips having to access Sullivan Road, This connectiQra to 5prague would be remvaed by i0stallatianof a cul-ae-sac fol[owing construction a# the future 5outh Va lley Arteriaf, as the existing Cvmprehensive Plan daes not identify an irrtersection at the vne-faalf mil~ at Cvnklin Road. Based an several recent studies vf the Sullivan Road and Sprague ►4venue corridars, for traffic v►rithin this generaf area to adequately access 5prague Avenue, an additiana! - - link east vf SuIlivan Road will need~ to be provided. 5tudies that were prouided tn the Cvunty indicated that any nevv residential traffic, as well as any existing residentiaf traffic, that cauld be remaVed fram tFae ,ullir►an Road corridor and rduted directly to Sprague Avenue will help SuIlivan, inot oraly in the shvrt term but alsa ira the Mvng term. Theretore, cvnsidering the high costs fvr recvnstructing the 4th Avenue and SuffiVan Road intersection, the sponsor's pre#erred alternative for this project is #v directiy access Sprague ►Avenue and the future South Vafley Arterial. Any tempvrary thTaugh conraectivn to Sprague Avenue rivas rejected by thae spvnsor since a temporary cannection would not pravid'e lang term relref for Sulli►►an Raad. The al#ernatiue of prvviding an easterly connection tb Steen and Flara Rvads wauld be expensive and beyond the sporasor's cvntrol and I Ithe scope of this project. Sha►nrock Street EartensiDn - This alternative wavld require extending 5hamrock 5treet narth from the exrsting temparary cul-de-sac withirr the Ratchford Acres plat directly into the Shelley Lake plat and connecting ta Road "N." Shelley Lake Draft E1S 22 . Februe.y 1994 The preiiminary plat exhibits presented at the scopinghearing shvwed this connec#ion tv Raad "N." During the scoping hearing, County presentation and testimony indicated that the primary through connection bstween the twa plats would be the Ratchfvrd [?riVe and Cankl+n Road connectivn, with poteniial aGCess at Shamrock Street prvViding a secondary connection point. 5ubstantial public testimQny rsvolved around this issue, with cvmments indicating that nQ connectivn wauld be desirable to the res7dents in the Ratc'hfard Acres psat, Therefore, the connectivn af Sharnrock - Stree# ta Raad "N" was remuved. Hvwever ta innprove northfsauth circulation east of Sullivan Rvad, the Conklin Raad and Ratchfard Drive cvnnection was maintained. The extensinn af Shamrack Street ihraugh the prvject tn connect ta Raad "N" would have the effect af dispersing traffic in #he area, thereby reducing tra##ic on Ratchfard Orive and improving neighbarhnad cantinuity in the area. The spvnsar's goa9 of creating a priyate comrnunity as well as area residents' desires ta preVent addit3vnal traffic vn residerrtial streets would be negatiue impacted by this alternative. GaIway 5treet Extensian - This aIternative would require extending Galway 5treet north from the existing temporary cul-de-sac within the Ratchford AcreS plat darectly inin the Shesley Lake plat and connectsng #o Road "N." This vptipn was nnt presented in the preliminary plat exhibits at the scaping hearing. As stated abaVe, during the scoping h+earing Gounty presentation and testimony iradicated that the primary #hrough connectiQn between the twv plats would be the Rvtchfard Driue and Canklin Raad cannection. Substantial public testimrany revvlved arvund this issue, with comments indicating that na cvnnectipn would be de5irable tv the residents in #he Rotchfvrd Aeres plat. The effect a# this vption is similar to the extensian of SFaa mrack Street d iscussed above. This additianal road cannection would allnw for greater dispersaf of traffic in the neighbarhood and less traffic concentration on Rotchford DriVe, and may result in a more cvhesive neighbarhaod. Additivnal road cvnnectinns will detract from the concept of creating a private comEnunity and will not be consistent with the desires expressed by Rotchfvrd Acre Tract residents to prevent additionat traffic in their neighhnrhoad. Re-classify►ing Road "N," Shamrock Street, Galway Streei and Court °F" as Public Roads - This alternatiUe assumes that #he previously discussed through cvnraectivns are made to existing or future public roads to the east via Rvad "IV" and to the sauth aia Shamrock and Galway 5treets. This vptian alsa rerroaves ihe PUD overlay zvne frflm #he 5uburhan Residential (5R-1) zaned portian af the praject adjacent to the Rotchford Acre Tracts. The Suaurban Residential-1 iSR-1 y zoned lots wold canfarm ta the minimum one-acre Ivt size, instead vf applying banus density as propQSed. This wauld Kesult in development that is cvnsistent with the one-acre lot sizes in the adjacent Rvtchford Acres Tracks, and reduce the avera11 density of the praject. The size ❑f the PU❑ area wvuld decrease and a private, srrialler PUD wauld be deVelaped.

Inflow to the Iake is provided by Saltese C reek, an intermi#tent stream which flavrrs into the sauthea5tern end of the lake. There is na surface nutflow. Accvrding to Lhe Recannaissance Data on Lakes in Waqbftton - Volume 7, Shelley Lake lies at 2,025 feet in elevatian, has a tatal surface area of 37 acres, a maximum depth of 41 feet, and a total r►alume of 710 acre-feet (see Eigure 5). HoweVer canditions have changed since thess figures were estimated in 1952 by the pepartment of Garrtie, and the lake has ssgni#icantly decreased in size. The ❑epartment of Ecology establi5heti the ardinary high water eleuatian at 2.009.1 fesi, 15.9 feet Ivwer than the e'leaatian preViausly reported by the Qepartment of Game. At this Ivwer elevation, the lake cvns'ssts of apprvximately 21 surface area, has a maximum depth of appraximatsly 25 feet, and a total valume of approximately 237 acre-feet. The lake`s water IeVel fluctuates seasonaliy in accordance with precipitativn amnunts and the resulting intermittent stream flow. Lake levels were rananitored fram late March through September during the course of this study. In late March the lake level was a few feet below the drdinary high water eIevatian. By 'rate May the lake Inad risen up tv this mark, but by mid June it had falien baek to helow its prevEOUS level. Similarly stream f law was high in late May, but by mid J une the strearrtibed was totally dry. The current prvperty owner reported that SaI#ese Creek flows into Shelfey Lake #ar anly a few weeks dur3ng the spring of each year. aite Visits in late June through Septemher indicated steadily decreasing vuater levels, estimated up ta approximately eight feet belaw the vrdinary high water efevation.

Healthy Iakes have a fovd web that involVes the fivw of energy among the lake nrganisms and the recyciing of nutrients. The process of phatosynthesis by aquatic plarrts prtaduces axygen, which is the primary source of dissvlrred oxygen in water. Oxygen is required tv sustain fish populatinns and is repuired tv completely break down arganic matter. ❑uring the respiration process, the bacteria that decampases arganic rnatter consumes oxygen and releases carban diaxide, water, arad energy. When incarning water is high in organic matter, the bacteria can cnnsume the Ia'ke'S di55alved axygen supply mare quickly than it can be ceplenished. This can lead to fish k6ils, vdars, and noxiaus conditions, and is most likely a majcrr contributing faCtor to the water quality limitat'rons of S'helley Lake.

Significan4lmpacts The current water quality of Shelley Lake has iheen degraded by up-stream and possibly on-site agriculturai practices. Sail additives such as fertilizers and pesticides have ar#ificially incteased nitrvgen and phosphorus le►►els within the Iake. Peai mining aperatiflns in the Saltese Flats have added substantially to arganic particulate matter inflaw. Decampositivn of this organic matter has depfeted dissolved oxygen suppiies. Vllithout oxygen the decvmpos+tivn prvcess is vnly partially compieted, creating anaerohic cvnditions which have 1ed to fiSh kills, reduced visibility, and odvrs.

This wvuld remaVe the organic particufate matter frvm the water aefvre it reaches the Eake. These efforts waufd reduce the deptetivn of dissnlaed Qxyger~ and imprsvs water visibility and clarity, impraving ualuable squatic plant protluctian, reducing adors, arrd improving conditivns fvr viable fisheries papulativns.

Due to the existirag agr'rcuftural use and Iimited supply durrng the dry summer manths when additional water would be needed in Shelfey Lake, there probably is nvt any excess water availabl+e in the Saltese Greek drainage (Farmer, DOE). Water could be i mported 'rnto the lake by pumping fram the existing vn-5ite well. The we11 Ing indicates that fhis well was constructed in 1956 and has a yield of 700 galfans per minute (gpm) . Rroperty vwners have retained a water righ# fvr irrigatian since the time of well development. However, same well vr►ater needs to be used this seasvn in arder tv maintain the current water right.

Assuming an eight fovt drop in the water Ieve1 from high vi►ater 7n eaeiy June tQ the lowesi estimatsd level in late surnmer, results in the Inss of apprvximately 168 acre-feet of water. Therefflre it can be estimated that the on- site welf wauld need to yield apprQximately 208 gpm pumping auer six rnonths of the year to replace water Iosi #o infiltrativn and evapvratian. If additional water is required fvr onBy four mvnths, then the well would need to pump at a rate of apprvximately 37 2gpm. These pump rates are esfimates only $nd do ncat take inta account yarying evapo ratign rates due to sessonal influences arad hydrau lic heaci pressure changes due to ffuctuating water volumes. Withdrawal of ground water cvuld pvtentia1ly impact ground water levefs, hvwever the pumping rates that may be required by this project are substantially less than the 70[] gpm rate that was prevFOUSIy pernnitted for irrigation use. Therefare applicatian of this management technique waufd have Iess of an impact on ground vvater supply kevels than farmerly permitted.

The prvject site's most prominent #eature is Shelley Lake which is bvrdered by the propnsed plat vn all but the east side. Shelley 'Lake acts as anatural sump area far seasanal fiows from 5altese Greek, which drains abssin to the east and sauth of apprvximately 22 squace miles. Since Sheiley Lake has no natural nutlet, all starm water which ,enters the lake is disposed of ihraugh percolatian and eyaparatian. - - The 124 acre project site is Yocated within the Garrisvn-Marble-Springdale soil assvciation accarding to the General 5vil Map of Spokane County, INashingtan (US Department of Agriculture Soil Consenration Service, 5oil Survea of Snokane County, Washinraton, 1968). This assnciation is made up of somewhat excessively drained and excessively draireed sandy and gravelly svils fnrmed ira glac'sal vvtwash. The praject site contains five distinct snil mapping units (GgA, GgB, GmB, StG, and SuE) vaithin the Garrisorr and Spakane series and an abandoned gra►►e1 pit area.

Dther than the SaItese Creek watershed, the prupased praject site does nat cantain any major drainage cflurses. Run-aff within the site is presentfy disposed of by natural means. Snow melt and storm water is generally absarbed by the permeable sails fvund within the area when the ground is not frazen. b. Ssgnificant Impacts The prvpased project consists of the develvpment of 459 residential units, including 195 attached residences. 68 manufactured homes, and 196 single-fannily residences around Shelley Lake. Rvads will be canstructed tv access the muiti-family area and indi►ridual Ivts. The characteristics of the sails in the area factvr inta the carrying capacity of the s2te tn determine its suitabElity far the construction of residences and roads. Table 2 autiines the characterestics of the 5oi1 ty,pe5 fi?uild pfl-51te. The additivn of a built environment has the pvtential to intensify the amount of run-vff and sediment Inading reaching Saltese Cree'k and Shefley Lake. The additivn of imperviaus surfaces to the site tFrraugh the constructivn of hvmeS, driveways, and roads wiEl result in the inability of water to be absorbed in the preViously undeveloped areas. The ixnpervivus surfaces wi9l create an enviranment with a farge volume of run- nff that rrvail need to be diverted and managed vn-site in a stoTM water system. Any accumulated run-off, if directed ❑ver a steep slaping area, will accelerate and increase its potential to carry sediments and vther particFes. AFong with the increased risk of erosivn, there cnuld be the passibility of incising the existing drainageways by the increased Vo9ume of discharge they must aCCVmmodate. All of these factoss need ta bs taken intv cvnsideratian in engineering a starm water managemen# plan for the development.

Affected Enwironment The 5pmkane regivn fypically experiences bvth spring snowrnelt and winter flaods. Spring floods sre caused by snvwmelt rurr-aff frvm higher eleuatinn watersheds and are influsnced by the amvunt afisnowpack, temperatures, and the tineing vf heavy rains during the criticsl snawmelting perivd. Winter #Iovds are the result of warm temperatures and heaVy rainfall, frozero soil cvnditions, and snowmelts praducing shvrt-duration, intense run-of#. Shelley Lake and the Saltese Creek drainage west af the Steen Rvad bridge are located within the "Un-numbered A Zone"' flvod zQne area acco rding to the Federal Emergency Management Agency (FEMA) map attached as Figure 7, This designativn means that a detailed study h as nat been cannple#ed for the lake ta establish ihe 1 aQ-year flaod elevation. The 700-year flood plai,n el'evation is defined as the wate r surface ele►vativn that would have a statistical prohahility vf ane percent vf accurring in any given year. A1 00-year flood pfain elevation af 2(]27 (fJSGS Qatum) has been established at the Steen Road bridge, which is loca'ted upstream and to the east of 5helley Lake. ' Prvperty vwners adjacent tv the prvject site have reported problems witFr fleoding in the area in the past. In addit'son, Spvkane Cotrnty Engineers files show that during a 1948 Chinpnk event, Sheliey Lake vverflowed and was abserved flowing acrvss SuIfivan and Conklira Raads. However a drainage channel leading to the Spokane Courrtyl$he#ley Lake Gravel Pit, northeast of the project site, currently acts as an _ emergency averflvw for Saltese Greek and Shelley Lake. This channel aqpears to be mastly of na'turaf origin, hawe►ver a newspaper article indFcates that it may be at Ieast partially man-made. This unreferenced nevvspaper article is qvoted as follows: "Remerriaerin,g.., Back in May, 154$ a quic;k thinking Cvunty Cammissivner and a bulldozer operatvr salved s big flvodirag prvblem.

A1Ffected Envirtinrnent The prvject site cantains seVer,al types of distinct plant carrrmunities including grassland, ponderosa pine forest, riparJanlwetlands, and shrubs. The majority of the site (approxrmateiy 8[] acres) is cultrvated fields that are currently used for the productinn of hay. 7kre existing plant cvmmunities and field edges provide a variety a# fvod, cover, and breeding habitats fvr wildlife at the site. Fiowever, extensive cattle grazing dawn to the water's edge has significantly disrupted the natural vegetation and eliminated most of the high value native habitat along the Iake's shareline. 7he Spokane County Soil Survey indicates the patential vegetatian of the develvpment site tQ be primarily bunchgrasses, daminatsd by bluehunch wheatgrass and 1dahQ fescue. Other grasses wDUld be 5andberg bIuegrass, '~ottlebrush squiereltail, prairie junegrass, and Columbia needlsgrass. Fvrbes cvmprise a lesser partion o# the site and may include biscuGtroot, buckwhea#, lupine, lomatiurn, arrvwleaf balsamroofi, sticky geranium, astragalus, cinquefaiE, Iarkspur, yarraw, and phlax. Native shrubs arrd trees which could be expected to accur would be distributed in small, scattered clumps and may include srrawberry, Rtf58 WC1od51i and R. nqtkang, chnkecherry, serviCeberry, birchleaf spirea, mackarange, arrd panderosa pine. Wetland areas along the Iake's eastern shareline cvuld be expecfed tv support a wider variety of wvody species including quaking aspen, wiRlaws, cottonwoods, Dauglas harnntharne, elderberry, and red-stem dogwood. Gultivated fieEds are located nvrth, west, and sauth of the lake {see Figure 8y. The northern and western Iake edges and the area surrovnding the abandoned meat packing building cans6st of a mixture of weeds, grasses, and afev►F shrubs. These areas extend #rmr~ the cultiVated fielri edges downslape ta belvw the lake's vrdinary Faigh water IeVel. The majvraty of the vegetativn in this area consasts of knapweed, an extremely undesirabCe r►veed that is difficult ta cvnTrol. Various grasses, perenniae forbes dncludirrg birdack, mullen, mustard, and toad#lax, and a few smafl scattered shrvbs are also fiound in this area. 5evera1 fir trees are Eocated north of #he existing Rice residence that are mare than 65 years nld. Six deciduvus trees are alsn lacated vvesx of the ahandoned rneat packing buii'ding. Varigus sma'Jf radents and insects are supparied by this vegetative area, howeVer these areas are of relatiuely 1vw value due to the high amount of knapweed relative ta existing natural Vegetativn. The extensive presence of knapweed Rn this area of the site can prabably be attributed to its past use for intensive catt9e graring. The grassfand areas of the site are Iocated alang the Saltese Creek drainage and extend snuth of the creek inta a seasonal flvad plain area. These areas cansist mastEy 5helley take Dreft EIS 41 Fe[sruary 1994 i of higher value native grasses and sedges alvng #he stream bed area. A smaller grassland area is located along the western shoreiine of the svuthern extension of the lake, and extends up a gentle s'lape to the cultivated fietd area, Granivvres (seed eating animals) and graaing herbivnres such as rodents and Fnsects are typically supported by this type of habitat. Grassland areas may also be used fvr hunting by predators such as hawks and coyote. Tihe btuff directly east of the lake suppar#s a poroderosa pine vegetative community that extends narth ta a graael pit'Incated northeast of the praject site and south tfl the Saltese Creek drainage. Steep slopes and rocky areas alsv suppvrt native bunch grasses, perennia'I forbes, and sma!# shrubs. This habitat supparts a variety of birds, small mamrnals, and occasianaPly deer by prvviding cover, breeding, and #eeding areas, an area of mastly native shrubs is Iqeated sourth and west of the sautheasterly extensivn of the lake. Yhis area consists of natiae shrubs, perennial f❑rbes, and grasses including huckwheat, blan ket flawers, Fupines, ya rraw, and serviceberry. This habitat prvvides cvver, breeding, and feeding areas for small rodents, 1115eCtS, and birds. Three areas of ri,parian Vegetatian are Iacated near the lake's eastern arad 5outhern edges. A srnalt wetland area extends fram the lakeshore nartheasterly into the blufflpondervsa pine vegetative community. No visible +evidence of surface water has heen nated in this area, howeaer se►►eral pcapulus s,pecies inCluding willvw and lvrnbardi are lacated here and southQrly alang the lake's shvreline. This area alsv contains shrubs including hawrthorne and wild rase. A second area of riparian populus sqecies is Iocated alvng the eastern lake edge, just north of the stream entrance. The third area of riparian vegetation is Ivcated at the tip of the lake's sauthem extension, west of the stream entrance. The relatiVely flat sla,pe and fine grain svil conditians found here suppvrt a variety of sedges, altFaough they are few in number. The riparian]wetfand vegetative areas support nesting and feeding opportunities far a variety of birds, small mammals, and aquatic insects. HvweVer, these areas are fairly limited in size and species diversity. TFre 1Nashingtvn State Department of Natural Resvurces was cvntacted regarding informatiQn an significant natural #satures in the praject area. A search of their data base did nat reveal any records of state endangered, #hreatened, ar sensitive plants or high quality raative pfant communities and wetlands. The fvllowing species of birds, animals, and fish ar evidence of their presence vuere vbserve+d vn-site during the course of this study; Ring-neck and cinnaman teal ducks, great blue heran, red tail hawk, pheasant, quail, flycatchers, krEideer, swaliows, r❑b+ns, filickers, kestrels, wren, chickadees, great harned awl, field mice, Voles, squirrels, marmats, turtlss, skunks, large mauth bass, and perch. Because of poo r water qual ity and ex#reme water fevel f luctuations, Shelley Lake d'oes Shelley Lake Draft EIS 42 Fe6ruary 1994 nat suppvrt a sigrrificant fQSh popufation. There rs alsn an ❑bvivus Eack of emergent marsh vegetation and therefvre na habitat areas are available for nesting waterfowl. The lake does receiVe use by migrant and resident waterfowl mostly during the seasanal breeding period. Other species that caufd be associated vvith the area but were not specificaEfy identified incBude coyote, badger, ermine, weasel, mink, and deer. Neighborhaod sightings on the project sote and within the immectiate Vicinity include hawCc, ov+rl, Qregvn Juncv and Black-capped chickadees, sparraws, rvbins, magpfes, meadawlark, ring-necked pheasant, Califarnia quail, hummingbirds, wmndpeckers, WEE$Q11°$ WBfbIer, everring grvsbeak, rufvus-s'rded tvwhee, Canadian geese, squirrels, coyote, deer, marmot, ermine, suspected waiverine, nuthatch, rabbits, #rogs, and turtaes. The Washington 5tate Department of Vllildlife was cvntacted regarding information on significant natural features, migration routes, and fish populaxivns associated with ShefCey Lake and ths immediate vicinity. A review of the State's data base did not result in the iden#ification of any species of concern wEthin a one-mi1e radaus of the project site. Their records of fisheries resaurces onfy indicated the presence of yellaw perch within 5helley Lake. b. Significant Impacts The areas of the praject site prvposed fivr the development of homes, stTeets, and associated utilities are 9ocated where there are relatiVely flat slopes which cvnsist mainly of cultivated fields. A soft pedestrian trail wall encircle the lake abvVe the ❑rdinary high water rnark, and samewhat disrupt the grass and shrub naturaE habitat areas. Devefopment of these areas will require the rerrrvval of knapvveed and some native pCant species and wil@ likely encrvach upvn some of the habitat areas used by wildlife. The loss of wild6pfe habitat resulting feam construction and deve[opment of the site will be an unavoidabEe impact for some of the existing wildlife that is unable to successfully relocate. The construction of residences and raadways wi1l cvmpletely eliminate all agricultural prac#ices ❑n-site. This vviii necessitate removal of the assvciated fringe and stubble areas bordering the fields which praVide caver, breeding, and feedlng fior a variety of birds, insects, and srnaEl rodents. Construction of the soft pedestrian trail thraugh grass and shrub habitat areas wifl a[so impact these same types of wildlife. Site design has aElowed fvr 37.9 acres of open space (including 21 acres of surface water) to be left unclevelaped t❑ accvmmodate the existing wildlife. As the site deveiaps oVer time, wildaife wi[E be farced ta mQVe to vpen space areas mr take afternate patlas in areas where existing paths and habitat will be removed. INild6ife will be expased ta a greater number of people, their associatied activities, and resuItan# naises due tfl t h e influx of reside nts to the area. Same species may be last Sheffey Lake Draft EIS 43 Februsry 1994 if they are extremely sensitiwe and cannvt adapt to the changed enaironment, even thvugh adequate habitat is prvVided. Hvwever, the open space provided by site design wili accomm❑date a Iarge portian of the existing wildlife. c. Mitigating Measures The praposed develvpment prvject will designate 37.9 acres as permanent open space, which includes the lake (consisting af 21 acres) and suEroundimg shoreline and riparian and ►rvetland areas. Zhis will a8fow for the preserWativn and enhancement of fihese sensitive areas and the surrvunding enVirflns by contralling human contact and use. The project wauld cantroi and restrict farge animaa-keeping, herbicidelpesticides, and fertilizer use in areas where run-aff could impact the lake and wetlands. Most of the undesirable knapweed along the lake`s north, west, and east sharelines wifE be eliminated. Wetland and shoreline areas will be enhanced by plarrtings of native grasses and shrubs of high Value to wiEdlife. The propvsed devefopment includes a svft pedestraan trai! ❑n the slape arvurad the perimeter of the lake. 7he trail will be Ivcated vn a slape within a 50-fovt buffer area established between the fake's ordinary high water eleuativra (as established by the Department ❑f EGOIogy) and tne individual prvperty bvundaries near the tvp of the slope. A brQadcast spray (Rvdeo) v►rill be vsed to control knapweed in the areas where it is most preValent. It may take twm to three years with se►reral applicatians per year to bring the knapwe€:d under cantrol. This spray vvill aIso eliminate the smalf amvunt af grasses and farbes mixed in with the heavy areas af icnapweed. In areas ❑f mastly natiVe shrubs and farbes with lESSer amvun#s of knapweed, the knapweed will he spot sprayed using Rodea in vrder to retain the exis#ing high value vegetation. Landscaping plans within #his area are farmulated to enhance habitat for campatible wildlife species. The areas cleared of knapweed will be reseeded with Sheep fescue ar a m6x vf draught-talerant hardy grasses and fvrbs with high wi8dlife habitat value. Gr,ass mixtures will alsv EncEude nati►►e wildflawer seeds. Appraximately 24-foot irregularly-shaped clumps vt native oR naturalized shrubs will be p]anted in these areas, with emp'hasis primarily away fram the trail and other areas subject to high human uselaccess. This wiil minimize disturhance to nest6ng and foraging svngbirds and quail.

The soie may nvt cetain envugh moisture throughout the summer due to its sandy and gravelEy nature. However the diversity of species present may be increased by intraducing drvught tolerant specEes such as srnoQth sunnac, Russian oiive, sand cherry, Tartarin haneysuckle, and 'Rocky Mauntain juniper. 7hese plantings wit} prvvide fvad, caVer, and nesting areas for many speciss of birds, rodents, and insects. Nest boxes placed in the apen space corridvr along the Iake's shorelines will prvvide increased shefter and nesting vppvrtunities for cavity nesting birds. Cattaifs, sedges, rushes, and similar types of matshy emergent Vegetation may be planted in the wetland area at the lake's southern extensinn, west of the stream entrance. This wil# accur Anly if the lake's water level can be controlfed and maintained and wEde water IeVel fluctuations are eliminated. If these types of plantings can be estabifshed, it will ,prvvide nesting and breeding Faabitat far waterfvwl where none currentiy exists. Standing and falEen dead trees (snags) wili be left uradisturbed in the ponderosa pine VegetatiVe evmmunity on the bluff east of the Iake. Tha snags proaide cavities #or cvver and nesting that are used by swallaws, flickers, kestrels, wrens, chickadees, and wavdpeckers. 5tanding dead snags Iocated near the pedestrian traifi may need tv be tvpped aff and some lim'hs remaved far safety reasvns if it is determined that they are a haaard. Minimum landscaping standards will be estahlished in the restrictiue c+o►renants for Shelley Lake to ensure time9y Iandscaping of disturbed areas. The co►venants will alsv stipulate that the lakesid'e 'boundary of the residential lots bordering the apen space cvrridvr surrounding the 'lake be landscaped using native law shrubs and ground cavers ~i.e. kinnikinnicky rather than lawns and culti►►ated shrub beds. This will pravide an apprmximately 10 to 1 2-fvat transitivn zane hetween natiVe and cultivated plantiings and wifl help to siabii6ze the stape.

Ths current prvperty awners (Rice) purchased the homesite and lake property in 1953 and constructed the current structure arvurad what was just a shell. Additions tv tIne home were completed in 1959, 1963, and 1988. TFae Rice family aIready owned the meat packing facility and feed fot and used the lakeshare property to raise cattle far their meat packing business. The vrigina4 meat packing building was canstructed in 1348, with additians in 1958 and 1960. The Rices irrigated the pasture land where the cattle grazed with water supplied by an a n-site weli. Cattle were re moved frvm the prvper#y during the mid 1970's and the pasture Eand was leased to variaus tarmers for agricultural (hay) praduction. The Rice's sold the meat packing facility tca Kurt NeaEy in 1986, wh0 filed fvr bankruptcy within fnur ye8F5. The building fielf intv disrepair and has since been vandalized severat times. The predominant characteristics of the surraunding area are ~urban and suburban with rural use eas# of the project site. The majarity of the prQperty immediately west of the site is owned by Centra!

Based on the advpted policies, an inteesectian with the Sautb Valley Arterial at Cvnklin Road wouid not be consistent with the Arterial Road Plan. Shelley Leke fJraft Ef5 69 February 1994 4th Avenue is a two-way, twv-3ans, 25 MPH, eastlwest local access street east of Sullivan and a two-way, two-lane callsctflr arterial west o# Sullivan Road.

Between Conklin alld SL1IliVanr 4th Avenue has sidewalks, curh, and gutter where adjacent develapmen# has CaflStflJCted #I1e5e Fmprovements. Between the project site and Sullivan it is expected that the nvrth side o# the roadway will have a continuaus curb, gutter, and sidewalk, as aII the available property will be deVeIoped into nnulti-fiamily apartment units. It is expected that by 1994, 4th Avenue bet►ween Sullivan and Cvnklin will have approximately 704 tv 900 apartrr3ent units accessing Sullivan Road via 4th Avenue. GonkAin Road is a twv-way, two-lane, 25 MPH, northlsauth Incal access street which runs between the praject site at 4th Avenue and Sprague A►►enue.

As shnwn in Figure 3, there are #hree existing street termini to the south in the existing Rotchfard Acre Tracts. These streets are Rvtchfvrd Drive, Galway 5treet and 5hamrvck 5treet. It is anticipated that the vnly cannection to these southern street termini will be via Rvtchfvrd Drir►e, which will be extsnded thraugh the pfat to tie directly into Canklin Road, The intersection of 4th Avenue and Conk9ln will 4e ~recanstructed sv that 4th Avenue will make a cucrre to the sautheast and tie intv the propQSed cur►►e on Conklin at a 90-degree angle. This realignment of 4th Auenue wifl require dedicatian of additivna'E right-vf-way to the Caunty, with the aptian of surplus Cnunty prcaperty being vacated to the surrounding property owners. Hvwever due to utility cvnflic#s, the project may canly landscape the existing County right-vf-way rather than have a public hearing fvr vaca#ian and realignment of utilities. Primary ingress and egress fvr the Prapased Actiorr alternative will be via Conklin Road nvrthlsouth directly #o Sprague Avenue. A revisivn to the Cvunty Arterial Rvad Plan to include an intersection at Canklin Road and the aouth Vaffey Arterial will be pursued as part vf the prapvsed project. It 3s expected that 4th o4venue will pruvide service directly to a small pvrtion af the proposed multi-famity area, which wi11 be cansistent with the ather 700-plus apartments currenfily existing or propased alvng 4th Avenue.

Based upon the existing zoning cade far Spokane Caunty, appraximatsly 264 single-famiiy and 195 multi-family units covld he and are proposed. 7he propvsed praject will generate variaus Volumes of traffic during canstructian of the several phases vf devElvpmenit, At Fhase 1 compleaion, which includes 58 single- family residential hames, the prqpased project will generate appcnximate4y 43 AM peak hour and 59 PM peak haur tr;ips. The anticipated tatal number of Vehicles which will be generated thraughQUt the day would be 590 vehictes per day (vpd). Of the 43 AM peak hour trips, 17 trips will be entering the site, while 32 will be exiting. Of tfae 59 FM peak hour trips, 38 trips will be enterirrg the site, while 29 will be exiting. At fulf build erut (2004), the prop,o5ed praject will generate a,pprox'rcnately 283 AM peak hvur trips and 375 PM peak hour trips. The antrCipated total number of daily trips whicYr wilf access this site is, expected tQ be approximately 3,750 vpd, f3f the tatal 2$3 AM peak hvur trips, 66 trips will be entering the site, whi[e 217 v►►ifi be exiting during the AM peak hnur. 10f the 375 PM peak hnur trips 246 wifl be entering the site, while 129 will be exiting4, At Phase 1 Cvmpletinn, during the AM peak hour this project dves nQt degrade the level oi servics beynnd the background LQS far any vf the identified 7niersections. Qu rin g the PM peak hour this projeIct wil l reduce the backgro und leve l of service at the 5prague Avenu+e and Conklin Raadi inter5ectinn. The specific reductivn in LOS is fram an La5 0# C, 236 pcph to an LOS of E, 88 pcph. Although this level v# service Shelley Lake Araft FlS ~ 77 Februery 1994 reduction seems excessive, it is vnly associated with a narthbound left turn vvlume change from four left turrrs without the project to 20 feft turns with Phase 1of the project. 6ased upon the analysis per#vrrned, nv direct specific irnpact which wvuld degrade the Phase 1- 1945 backgrvund leve!' a# sen►ice of the surrQunding stceet system can be determined, wath the exceptxvn of the Sprague Avenue and Conklin, Rvad intersectian during, the PNI peak hour. HoweVer, in conjunction with the expected grvwth levels associated with this lacativn within Spakane County, tiurtng the IPM peak hour this interseetion daes not dro p belnw the miraimum acce,ptable LQ5 of E for an unsignalized intersection within Spakane County. At ful4 huild o ut 42004a, during the AM peak haur th'ts project will reduce the fe►►els of service beyund the backgrvund IeVels of service at twa intersectivns. The first intersection is the unsigraalized Sprague Avenue and Conklin Fioad intersection, where the 2004 background LOS of A(473 pcph) and the LOS with the project is anticipated ta move the intersectian tn an LO5 of Q l ti45 pcphy. Although significant in the fact -that the auerall reductian is three Ievels of serVice frflm an L(3a of A to an L05 of p, this reductivn in LOS is still above the minimurn acceptable LO5 as identified by ,p❑kane Cvunty. The second intersectivn to experience a reductian irr L()5 is the 5uflivan Raad and Sprague AWenue intersection. This intersectivn reduces frvrn ara LO5 of f] ►rvith an aVerage delay of 35.0 secands to an 4OS of DlE with an average delay of 41.8 secunds. Although the LO5 D level is exceeded, an incrsase of 5.6 secvnds of total delay is arbitrary ciue tn the somewhat subjective nature of signalized in#ersection ievel of serVice calcufatiorrs. Usually the rute a# thumb wouid state that with mvre aggressive signal timing, incorpvrating sharter cyCle lengths, and incorparating mare right turn on red or left turn permittedlprotected phasing, a ten ta 25 percent reduction in delayv can be achieved. In vrder ta maintain continuity between level of service calculativns fmr review, these tirning revisions •were nat incvrparated. Therefore, an average defay change frorra 36 tv 41.6 5econds cvuld be consideted to kre very little change, if any a# all. Additionally, the primary reasan for the increase in Lf}S is due to the averall increase in traffic volumes at this intersectivn and the reductian in green time #or tFre eastbaund and westhound directions given the larger through vvlumes along 5ullivan Avenue. Therefore, if there were snare through lanes available far #hraugh traffiC progressivn or nvrthbnund left turns, the overall interse+ctEOn leve1 of service cauld be maintained within the acceptable limi#s of no iess than an LOS of D. AI'thvugh the charage from an LO S of p(36.0 secands) to an LvS of E(41.fi secands) carries the intersectian through the L0S of p1E threshald, se►rerati tirning revisions cnuld be incorpvrated to minimize ar negate the impacts. The rea1 measure of this signa lized inte rsectian's ca pa bilities to ha ndle the added traffic valumes is tha# the v1c ratio moues fram a background v!c ratio of 0.78 tv a Vlc rativ o# 0.89 with the .5helley Lake Oreft E15 78 February 1994 I aIternative. Therefare, this intersection maintains adequate capacity to handle the I volumes geneGated by this prapased project as we1l as the backgraund growth, but the signal timing and existing lane configurations dv not aliaw the intersection to operate at it's maximum patential. auring the PM peak Frour this pr,vject will reduce the SuEEivan and 5prague and tine 5prague and Conklin intersections below the ieVe1s of service frnm the background growth in traffic. As with the ear1ier discussions, the levels of serWice reductions ❑n 5prague pvenue are not reductivns on 5prague Av;enue, rather they are the result of additicanal through ►►nlum+es an Sprague Avenue and;this through traffic's impact on the intersecting side streets. The impact ta the intersdcting side streets is usually in either the narthbaund Qr sauthbaund urasignalized lefitl turn. As indrcated far Phase 't completian, the irrcrease in bath thraugh traffic a'n Sprague and an increase of 16 left turns reduced the reserve capacity by 150 rrehicles, The same is true far PFrase 2 evmpletion, where the increase in northbound Ieft turns is frgm apre-deVelaped ►►alume of four to a build vut valume of 68 left turns at th~ 5praguelCankiin intersection, lt shauid be nated that this volume is apprvximateliy half that of the left turns in the AM peak hvur. hloweVe r, the higher eastbvund c'vmmuting Walumes on Sprague and the cvnflict that they pxesent fvrces this intersect~ian to an L+DS of F, with a reserve capacity of -35. - As noted earlier, this is due to theiincrease of 64 additional nacthbound t❑ westbaund left turns frQrn Garrklin vnto Sprague. It should be noted that tYre intersection reserve , capacity is being reduced by faur' times the number of added Ieft turns, This type of capacity reduction is indicative of i ncreased thraugh traff ic Vvlumes on the intersectirag ' street, in this case Sprague AVeniue. At the Sul€irran Rvad and 5prague Averiue intersection, the red uctian in IeVel of sec►rice 'created is two fald. First, the increase Fn thraugh VQlumes due ta cvnsiderabte background growth, combined with an increase in lefit turn Valumes #vr aecsss tv the prnpased Fred Meyer #acility, have pushed this intersection beyvnd it's capacity #v serve the expected grawth. By tkie year 2004, vvith a taackgrvund level of service at an LOS of E(90.2 secorads), the additional delay and ievel of service reduction ta an LO S of F (1117.7 second'sy is the result of the southbaund to easibvund left tu rn heing beynnd capacity with nn additia;nal green time available ta improve thss level of serUice. In the event that ihe County were to cvnstruct dual !ef#s at this intersection as part of the 5u11iVar~ Road improv^ement praject, LOS at this iratersectian will increase ta an LQS of E with an average Jelay of 55 secvnds. b.2 Develapment Under Existing Zoning Alterneti►►e 1 As with the Prvposed Activn alternative, trip generation estimates were prepared fvr the maximum pvt8ntial for this alt~ernatiVe. Based upon the existing aantng cvde fDr 5pokane Gounty, apprax3mately 2~5 single-family uni#s could de proposed within the Shelley Lake prvject site. 5helley Lake Draft E15 79 rv February 1994 This a4ternative will generate variaus volumes of tcaffic during constructicin of the several phases of tievelvpment. At Rhase i campletiQn, which includes 58 single- farnily residential Yaomes, the project site will generate approximately 43 AM peak hQUr and 57 PM peak hour trips. The anticipated tatal number of Vehicles which will he generated thrvughout the day would be 570 vehicfes per day td,pdf. []f the 43 AM peak hvur trips, 91 trips will be entering the site, while 32 will ae exiting. Of the 57 PM peak hour trR,ps, 37 irips will be entering the site, while 20 will be exiting. At fu11 b uild aut (2004), this alternatiae will generate apprflximately 't GC ANf Peak hqur trcps and 228 PM peak hour trips. Ths ant€cipaked tvtal number of daily trips which will access this site is expected ta be approximately 2,280 vpd. Qf the tatal 166 AM peak hour trips, 44 trips will be entering ihe site, while 122 will be exiting during the AM peak hour. af the 228 PM peak h+vur trips 14$ will be entering the site, whise SQ will be exiting. At Phase 7 cvmpletion and full build out (2004), during both the AN{ and PM peak haurs this altsrnative will onfy affect the reserve capacity of the 5ullivan Road and 4th aVenue intersectinn. It wilf nat degrade the level of service beyvnd the backgrvund Lfl5 fvr any of the identified intersections, sncluding the : ulliVan and 4th intersection. Based upan the analysis per#ormed, na direct specific impact which would degrade thE Phase I- 1935 background le►►el of serVice of the surrvunding street system can be determined. The vnly significant change cancerns the degree of irnpact and nat the level of serviee. The AM peak hour reserue capacity of the Sullivan and 4th intersection decreases frorn an LQS of F (-21) to an LOS of F(-143). This signifies that due to increases of thrvug h traffic Vvlumes aEo ng S ullivan Road, any increase in trafffC Gr1 LhB 8djaCeflt 51de 5tf$et5 WIII noticeably reduee the available gaps tv a greater degree than the specific number of cars added. An example of this was discussed for the Proposed Actaan afternatiUe, where 64 lef4 turns vvere introduced and the reserVe capacity was reduced by a 4:1 ratin. ~he impaets at full build out (2004) are similar to those described abave far Phase 1, vnly the degree of severity is complicated by deVelapment further sQUth of 4th Avenue, anci nat necessarily by the deuefopments along 4th Avenue. Hawever, the turnirrg valumes vntv 4#h from Sullivarr are significsnt and would fvrce thv`s intersectivn tv nvt only meet several warrants for signalization by the year 2004, but wvuld aIsv resu'It in significant intersection impravement5 such as Ie"Ftt turn Ianes and intersectinn signalizatirrn. a.3 Nv-Actian AItarnativa ` For this project alternative, there wilZ be nv addit+vnal trips generatecf than currently are generated by the existing praject site. No impacts tv the future transportativn system other than from Ibackground growth could be attributed ta the project site. Shelley Lake Oraft E15 80 Fe6ruary 1994 c. {IAitigating Measures Potential mitigatian vrras investigated by altematEVe for those +dentified intersectivns affected by the proposed de►►eIopment of the Shelley Lake praject.

At this tirne there is very little mitigation that cauld he recacnmended except that this project could participate in the deVelv,pment of dhe futvre dual left turns which will be required an bo#h of the nvrthbvund and southbound iegs of the intersection. HaweVer, due to the facatian of this prnfeet, partiGiQation wnuld Qnly be lirnited tv the percent tra#fiG participation far the sauthbvund (PM peak haur) dual left turn lane.

However, tihis alternative specificafly re-aligns #he praposed 4th Auenue and Cunklin Raad intersection tv aflvw through traffic, with a home based- work arientation, to acGess 5prague Avenue rather than tn afkow traVel down 4th Avenue tv SulNivan Rvad. Therefore as praposed by this alternative, mitigatfon is to atlovv for the reaiignment and reconfiguratian of the 4th Avenue arrd Conktin Rvad intersection. ►As pre►rivusly discussed, this realignment will require dedication of additional right-vf-way tQ the Cvunty. 5urplus County right-of-way could be vacated to the surrounding property vwners following a pu61ic hearing and appraual by the Baard of Caunty Commissianers, Sprague Avenue and C+vnklin Road - Based upon the existing, #uture hackgcvund, and futc,re Phase 1 as weli as future Phase 2(build +outl levels of service, this intersection wilw continue to aperate within the minimum thresholds of ieael of service as identified by Spokane Cvunty.

During the PM peak hour, far future backgraund as well $s future with the praject, this intersection will aperate belvw the acceptable levels of service. 1t is expected that all vehicles assQciated wit'h ths prvject site will'6e through vehicles at this intersectivn. ln the event that 5pakans Caunty were to revise this intersection by providing additionaf thrvugh lanes, it wou4d be recamrnended that this project participate to the percent level of responsibility assvciated v►rith the aolume of trips. aullivan Raad and 4Fh Auenue - Based upan the existing, future background, and future Phase 1 as well as future Phase 2 (huild aut) levels af seraice, this intersection wilf cantinue ta Qperate helowv the minimum thresholds af levet af ser►►ice as iderttified by Spvkane County.

The analysis prv►►icied spiit tfie traffic leauing the project si#e, based upnn travel twme and speed, and indicated that 4#h Avenue tv Sullavan Rvad wauld be the quickest way to reach #he SulliVan and Sprague intersectifln. This is primarily due ta a right tum at Sullivan and 4th versus a left turn at Gonklin and Sprague. Recommended mitigation far this aIternati►►e wauld include plat reconfiguration, tQ the point o# the lass nf additional 1ots, to realign the Canklin Road!Ratchfurd DriVe and 4th Avenue intersectian.

Districd No. 5 provides serr►ice ta the area extending fram $ullivan Rvad an the west tn the state line ❑n the east a nd from the Spokane River vn the north to the hifl tvps an the south. District No. 5is bordered by Qistrict Nv. 6 north of the river and District Nv. 3 west of Sullivan Rvad. There is ane patcal car assigned to cover esch of these districts an a24-haur per day. 7-day per week basis. 5hifts 7n rnanpvwer demands sometimes leave vne of these districts unpatralled for short perivds of time, ho►Never patrol ❑fficers aften overlap distrECt boundaries. 6ackup to C3istrict No. 5 is pravided by adjacent District Nas. 3 and fi. Response times to the area depend on the type of ca11, the Ivcativn of the responding afficer, his current activity, and the time of day. Gurrently there is nat adequate police ca►►erage #or the County as a who9e. There are plans far expanded serVices including additianal officers if more funding is made available to the Qe,partment. A study was recently cvmpleted by ihe 5her'sff's Department Crime Prevention Unit concerning crirne rate percentages per type of residential neighborhaod in 5pvkane Cou nty.

Sigrniftcant Impacts The additiort of 459 new residences and the related increase in population will add to the Sheriff DQ,partment's responsibility to provide adequate pafice protectivn to this area of the Cnunty. As population in the area increases, so daes the number of crimes ~ camrraitted and the mvre people #hexe is requiring service. Praject desigra includes the Qxtension of Ratchford Dri►►e north ta a connectivrr with Cvnklin Rvad. This cannection wauld make Rvtchford Dri►►e a collectvr arterial, impacting the existing neighbvrhovd orr the cu4-de-sac at the north end ❑f Rotchfard OriVe. Accvrding tv the crime rate study corrxpleted by the Sheriff's Departmeni, the Shelley Lake [)rafz E15 85 Fe4ruary 1994 i homes on xhe existing cul-de-sac have the lowest potential crime rate in the Gounty. A change tv an arterial roadway would put these hames in the 19% pvtential crime rste category, an iraceease of 4°r&►. Instead of being at a lacatdon with tFoe lawest crime rate, the rate at these homes wou[d be equal to the overall Cnunty average. The Rotchfard DrivelCvnklin Raad cannection and resultant creatian of an arterial may impaCt frant yard use En dhe existing cul-de-sac neighhorhoad. The additivn of mnre people ta the area and their increased mobility also vuould limit dhe recagniti+on ❑f strangers. Develupment of the area will result in shvrt-term ar limited site visits by - canstructian workers, real estate agents, pr potential buyers. This will reduce the resident's ability ta eecagnize patential criminai hehavimr. C. Mitigating Measures Many of the pateniial impacts that cauld haUe heen crea#ed thrvugh development of the prflject site have been mitigated thrvugh the proposed 51t8 de51g[3. Hauang a significant number of cul-de-sac streets and onl'y twa access points intv the develapment limits the patential for burglaries and vther crimes because ihe perpetratar -can easily be carnered by responding patrvl nfficers. The private cvmmunity type of design prapased, which includes perimeter berming and fenGing, typically generates les5 calls than ihe grid type of street design with multiple access points.

Affected Envirvnment The project site fies withira Central Valley Schao4 District No. 355. Schoals that serve ~ the area include Adams Elementary, Greenacres .1r.

Greenacres Jr. High is located at Main Avenue and Tschirley Raad, approximately ane-ha1f mile nar#heast. Csntral Valley High is adjacent vn the west of the site. Students would be bused tv Adams Shelley Lake Draft E1S 86 Fe6ruery 1994 Elernentary and possib4y to Creenacres Jr. High, but wauld wafk tv Central Valley High. Currently the DiSfirict`s twelve elementary schavls are nearing maximum capacity.

The seVen junior high schovls rnay reach this point in the fatl af 1393 and require student busing out of E►►ergreen Jr. High. The 0isirict has plans to construct a new elementary sch4al at LRberty Lake and adsi twelve new classraoms ta the elementar►y schavls throughout the system. Attendance boundaries would #hen be adjusted to ease cangestian. In addition four new classravms are planned at the juniar high IeVel.

The District plans to caratinue submission of a bvnd issue in future elections. b. Significan4lmpacts When fully built aut the propased develvpment vvill ad'd apprvximatefy 932 new residents tv #he Central Valley School District (2.35 res3dents per 264 single-family units a nd 1.60 resido nts per 195 multi-family units). Ap praximately 274 n e w students wo uld need t+o be accvmmodated hy the schovl drstrict, cvnsisting of 160 e lemeratary, 90 juninr high, and 24 5enior high students. These prajections were generated using Shelley Lake Araft EIS 87 February 1994 student generativn factors per type of hausi ng unit from The Npw PractMtiane r's Guide to Fisca! AnalyLis supplied by the ❑istriGi. Since full build out of the development wili occur vver an eight to ten year period, the District would nat immediately need ta accomrnodate all 274 nevv students. The influx af students wauld be gradual nve r the entire construction ,periad, Approximately 50 dwelling units vvould be campfeted each year, and `rf the phasing schedule fallaws the develapment plans, there wuuld be sp proximately 30 new students intrvduced intv the District each year. - Adams Eiementary is nearing "rts maxirnum capacity antf Greenacres Jr. High has limited remaining capacity. These sehavls wvuld be impacted by the addition of raew students frnm this and ather residentiat de►relopments propQSed far the area. This may require additivnal husing of students outside tFaeir heme boundaries, especially - vvithin the elementary schovls. Currently there is adequate capacity at Central Valley = High tn accnmmodate the additianal students generated by the propvssd praject. The addition af students to this area may facilitate the need for additipnal schoal bus $BfVIGFrr including the pvssibility a# additipnal bvses and routes andlar rnute revisivns. c. Mitigating Measures To accvmmvdate existing and future student enrallrnent generated by th'rs and other development prapvsafs in the area, the District needs ta carnplete their existing expansion plans. The prvpvsed Ibond issue would allaw fQr construction of a new elementary school serving the Liberty Lake area and additianal classroams at sevsral elementary and junivr high sc'hvv9s. The []istrict has alsv requested that the deVelaper negotiate a-voluntary agreement tv mitigate the praposal's irrapact on public schovls. This agreement may help to fund the a;strict's canstructivn, land acquisitivn, ar capital impravement expenditures, including the purchase vf portable cIassrvams if necessary. 3.3 Parks and Recreativn . 8.

F'ark facilities in bath these areas do not rneet the needs of th+e existing pvpulativn. Tfiere are three basic cfassificatimns o# parks within the SpQkane County park system; neighbvrhvad f commEUnrty, and Tegional parks. ►4 neighbvrhaad park is intenrled tn serrre residents within a one-mife radius v►rhere the majarity of the user5 wa4k• Ideally - tlhey are locaded in th$ center of a neighborhvad. Children between #ive and 12 years fl# age are the ,primary users. []esirable size is between three and ten acres, with two acres per 1,000 in po,pulatian prvvided. A community park serves more than ane neighbarhvod and users frequently driue ar bicycle to them. Amini~um of ten acres is desirable tv senre residents within a xwo and one-half mile radius. The range of facilities provided is greater than for nerghbarhaod parks and may include swimming ,pools, picnic shetters, tennis caurts, - soccer and baseball fields, trails, restrovms, and parking fots. Desirable size is 20 ta 50 acres, with 2.5 acres per 1,000 in papulation pravided. Regianal parks, within one hnur's driving time, serve large geographical areas and are generally at least 100 acres in size. They are typicafly areas with outstanding natural features ar quafities associated wi#h such featWres. pctiuities typically Rnclude picnicking, boatirrg, fishing, swimming, camping, and trail use. The two parks closest to the prvject sifie are SuIIiVan arrd Terrace View. Suflivan Park is located vn the north side of the Spokane RiVer at Sullivan Road, appraximately Qne and one-quarter miles nvrthvuest of the project site. This ten acre community type park has 1,400 feet of shareline an the rirrer and has three shefters with 12 picnic tables. Addtitional facilities inckude darhecues, dranking fountains, restrooms, pIay equipment, and hiking trails. There rs aFso a Western Square Dance Associativn building and a Radiv Gantxalled Car Club track and annauncer's baath. The Centennial Traif fo1lows the river's sauthern shAreline just sauth of Sulliaan Park. There Fs pvtential fvr expansion to the west on vacant, tree-cvVered land. Terrace View Park is lacated at 24th and Blake, appraximately one and ❑ne-hatf miles sauthwest of the prvject site. This nine acre neighbvrhood park has 24 picnic tables, shelters, rlrinking fountains, restraoms, pfay equipment, a saft4all field, and a swimming pvvl with a bat'hhouse. There is pvtential for expansipn of this park an approx+mately eight acres to the north. Li'berty Lake and MeadowWvad golt caurses are both lacated off Ualley Way and Mnlter Road in Liberty Lake, approximately five miles nartheast of the project site. These Gvunty-flwned cvurses are both 18 holes with driving ranges, cart rentals, pro shops, and clubhausss w~th restaurants.

The section lying between Rirrerfront Park and the T. J. Meenach Bridge is nat yet completed. The trail a4so extends 12 miles east fram the stateline tv Post Falls, Idaha. If f unding is made available, the Trait may sorneday extend thraugh Cveur d'A1ene to Wolf Lodge Bay on Lake Coeur d'Aiene. The trail is lvcated approximately ane and one-quarter rniles north of the project site, along the svuth shore af the Spokane Ri►►Qr. The tcail accammodates bicyclists, pedestrians, and the handicapped on right-of-way that is mostly separated fram motor traffic. LibeRy Lake Regionaf Park is approximately 2,975 acres in size and is lacated - approximately six and one-half miles east vf the project sFte. kt extends two full miles from the southeast lake shvre ta Mica Peak`s nvrth slope and includes meadvw and pine forest areas, a sand beach, and a marsh bordering the shnre. Facilities include restrvvms, drinking fountains, shelters, 70 picnic tables, barbecues, campsite areas, trailer hookups, aswimming beach, observation pier, and hiking and harse trails. Recommenda#ions far the West VaIley 5uburban Area include expanding Sulliuan Park to the west, addsng hiieing and riding trails, Terrace View shauld alsa expand thraugh the acquisition of approximately eight acres to the narth. ln the East VaIley Suburbarr Area, stated recommendations include acquiring Shelley Lake and developing it for recreational use including ajuVenile fishing facility.

The Cvunty Parks Departmerrt cuirrently dves nat haue adequate financial resvurces ar►ailabfe far park land acqursitiom In addition, pri►►ate land dvnativns ta the County park system have slowed substantially due tv achange in tax laws making this less financially attractive. h. Signi#icant Iranpacts The prvpased project will add 459 new residences to an area that was previous1y undevelaped. These new residences will impact the County park system by ancreasing the demand for park space and facilities at existing parks in the area. The majarity Shelley Lake Draft EIS 90 Februery 1994 af the impac# would be on organized sports facilities (ball fiefds) in the area, since these facilities are already heavily aVertaxed. QeVelopment vf the project site will preclude Shelley Lake's acquisitivn by the County Parks []epartment as recommended in the 1989 Plan. lt wauld nnt be deVeloper3 for recreatianal use by the generat pubiic, but wauld pravide recreational oppQrtunities fnr residents of the PU[3. c. Ililitigating Measuras The propQSed project includes the develaprnent vf reereational oppvrtuni#ies gvr 5helley Lake residents that will partially miti$ate some of the impacts nn the existing park system. This includes 8 5D~'C'C pBdeStrl8n trail in the open space corcidvr surrQunding the lake. Trail use wilf include walking, jvgging, crvss-cuuntry skiing, and birdJwildlife ohservatinn. The trail will extend dawn to the lake in several places tv all~~ for shoreline fishing andlar swimming access. !ce skating could be passible on some pvrtians of the Eake du ring the winter, Areas are designated within the plat f o r the future develapment of picnic, beac'h, dock, and cammunity eenter facilities if propased by the hameowner's assaciatiora. A future cQmmunity center could be IQcated within the existing meat packing building. All the existing wQVden structures, window glass, ar~d mechanzcallelectrical systerns wiil be remmVed and re,pairs made to the roof as necessary as part of the proposed pro]ect. The center cauld potentianally contain meeting areas and educatianal materials cvncerning wildlife hahitat enhancement and fisheaies management programs. aecisEans concerning recreativnal uses af the ❑pen space areas will be guided and centrolled by the restricti►re cavenants. These covenants, adopted by the Shelley Lake Hmmenwner°s Associativn, wif6 encaurage recreativnal activities that are compatible with open s,pace preservatian and enhancement goals and restrict thase that are disruptkve to ths community. The addition o# hausing units and therefare an increased tax base daes nvt necessarily result in increased puhlic park services far the community. Other serVices considered m❑re vital tn public health and welfare (i.e, law enfQrcement, public sewer, water, and road5, etc.) receive a substantially Iarger proportion ❑f available #wnding. Cf approved by the Baard of County Commissioners, developers may he required to negatiate voluntary agreements to mitigate impacts on parks and recreatian. The praject prapanent is required to sign a doGUment agreeing to future mitigation impvsed by the Board of Co unty Cvmrnissivners in ❑rder to get p relirninary plat approval f rorti the Cvunty Planning Department. Adecisivn by t'he Board a^f Cvunty Cornmissioners cancerning the amount and applicability of using impact fees far rnitigation is expected near the end of the year. These funds could be used to hel,p mitigate impacts of the propased derrelapment on the Cvunty park system. Hvvvever, established impact fees are nnt expected to he significant enough to provide for park Iand aequisition any time in the near future. Shelley Lake Draft EIS 91 February 1994 ~ { 4 Fi I 3. re Rratectian a. AIffBcted EnvlrUn~'1'17ent The project site is Iocated whafly within Spokane County Fire Protection District Nv. 1. District Nv, 1's ser►►ice boun6aries extend fram Har►ana Street nn the west to the Idahv stateline vn the east and fie basically within the foothill areas to the narth and 5auth. Stations seraing the proj~pct ar$a are all manned 24 hours ,per day by two or three people. The project vicinity is currently sen►ed by Statian No. 5lncated at SuffiVan RQad and Broadway AVenue, approxFrnatefy ane mile north of the prvject site's svuthern boundary. The average response' time is estimated to be apprQximatefy three minutes frvm receiving the emergency c6ll #a arrivirrg at the scene. Access routes wvuld be south nn 5ullivan to 4th and #hon east on 4th to the prvject site. This statinn is equipped with a 600-gallon capSCity engine that requires a minimum af two peopie to transpvrt and vperate: The stafiion also has a squad truck corrtaining first aid equipment and suppfies. Same response cvufd alsv come from 5tation Na. 3 Iocaxed at East 19200 Appler►vay in Greenacres. The average re'sponse time frvm this statian is estimated to be approximately fi►►e minutes. Access rautes woufd be r►vest on Appleway to Sprague, west vn Sprague to Canklin, and~svuth on Conklin to the prvject site. This station is also Qquipped with a CQQ-gallan capacity engine, along with a brush truck. The faur- vvhee3-drive brush truck is designed fQr vff-road fire fightirrg and carries a2Om-gallon water tank. Fire District No. 'I has plans to mQ~ve Statian Nv. 5 to near the Spokane Industrial Park at Sullivan Raad and Marietta Avenue in the Fa~l of 1994. ►4 multi-purpose vehicle that includes a Iadder, pump, and water tank is propased fvr additian to this statian following reloeatian. Qurirsg the same time frame, a new station 4N0, 7) with atWo ar three person engine will be a'dded at Evergree~n Raad and 7 Zth Avenue, This statior~ will be focate~i approxima~tel►y one and one-quarter miles west af the prvject site and have an aVerage response tirne pf approximately three minutes. ►4ccess rvutes to serVe the nvrthern p&tiQns af the project site wifZ he east arr 12th to Sullivan, nvrth an Sullivan to 4th, and west on 4th. Access routes to serve the southern pvrtnans vvEll be east ❑n j1 2th to Sullivan, sauth on 5ullivan to 'I 6#h, east on 7 fith to Rvtch#grd, and north an Rotchford to the praject site. The new Statian Na. 7 will definitely have first respvnse to the project site, Faawever both relvcated Station IVo. 5 and the new 5tation No. 7 v+uould serve the der►elaped project. Svme additional respanse woufd also be ohtainedlfrom 5tation No. 3. b. Significant Irnpacts , An additional,459 res'rdential units on 123,$ previausCy unde►reloped acres will be added to the reSpQnsibility of Firle District Na. 1, This resppnsihility will be added Shelley iake Oraft EIS 92 Fe6ruary 1994 gradually oder an eight-ta ten-year huild-vut perivd and will not occur immediateiy ar at arre time. ApproximateEy aa units are expected to be develvped per year, ' depending on market conditians. The cumulative impacts of the propvsed action may result in an increased need for addit'ranal manpvwer and equipment in the area to prvvide adequate fire pratectiarr. c. Mitigating Meaaures 7he deueloped project will have fire hydrant5 lacated according to Caunty standards thraughvut the site to pro►►ide an easy and ampie uvater suppfy far fire fighting purpases. The an-site water system suqplying these hydrants will be sized to prvVide adequate fire flvws and designed according to 5pakane County standards and the County Fire Marshall. Residences arad related structures will be constructed in accordance with Spokane Cuunty 6uilding and Fire Codes and the Unifvrm Fire Code regulations €ar fire vvall construction. Restrictivns vn the allowance vf nvn-fiire retardant building materials and wood shake rvofs wauld help cantrol the spread af a 'Fire i# ane were to vccur. First respanse to the developed site would be frvm the new Statipn Na. 7 at 12th a n d Eyergreen. If a fire were to occur in the southern portivn of the site, #he fastest respanse fram this sta#ian wvuld be accessing the site fram ths south nff of 7 fith Auenue. If no access to the site is prowFded from the south, fire response vehicles from Stativn Ne. 7 wouEd haVe to baektrack to the nQrth and return south frvm 4th pVenue. 7his woufd add several minutes to the respanse time to the site's soGthern portian. Pro►►iding a southern access route wauld #herefare keep respanse tirnes to a minimum. Qther nptivns to a full public right-af-way or private road to #he sauthern portivn af the site were exp3ared with Pauf Chase, aivision Chief of Firs Prevention fvr pistrict Na. 1. An emergency access roadway cauld be cmnstructed and cfosed off with an electric gate. The Fire Departmerrt could then apen the gate using their ❑pticom system, which is a pulsating strabe ligh# that is used to turn traffic signals green during emergency resparases. However, police and amhulances cvuld not use this access route because they dv not haue access to the Opticom system. Crash gates and roll-over berms with iandscaping cauld also be a rneans to prvvide access for emQrgency vehicles aniy. The Fire Department wvuld nat encvurage this type v€ limited access because of the damage it causes to fire engines and other errfergency vehicles. ,5helley Lake Draft E!S 93 Februsry 1994 ~ a'4 , - : ~JYe-~; ~'3~i ' A • ^ i ~ t~s=xn ~ ' x • . 3~ ~ 7 -drs• e.ff.'~i-~~"Y'~~'Li} n1 ~ ~ ~ ro ' ei' ~ n•~ - - • . • _ , y • _ • =S h ~ .
