FINDINGS OF FACT 1, The subject applicatian seeks approval of a prelimznary plat to subdivide approximately 4.27 acres intv 141vts for single-familv dweltings, in ktze existing Urban Residential-3.5 (U"R-3.5) zane. 2. The site as generally lacated north of and adjacent to Eighth Avenue, apprvximately 250 feet east of Bowdish Rvad, in tYte NE 'Ia of Sectivn 21, Tawnship 25 Ncarth, Range 44 EVVM, Spokane Caunty, VVashingtan. 3. The site is curcently referenced as Cou.nty Assessor's tax parcel nos. 45211.2{]21 anti 45211.2024. The site is 1egally described on the preliMinary plat rriap of record. 4. The applicants for the prvposal au-e Ken Tupper and Srian Belshy, 1220 N'orth Howard, Spokane, WA 9920 1. The owner of the site is Jacomena Aleffi, 11513 East 80' Avenue, Spokane, WA 992(lb. 5. The Hearing Examiner heard the prvpvsa.l pursuant tra the Cnunty Hearing Exarniner Drdiraance (Cvunty Resolution No. 46-0171) and the County Hearing Exarniner Rules o£ Pracedure {Cvunty Resvlution Na. 96-0294}- 6. The Hearing Exaniner conducted a site visit on January 29, 2002. 7. A public hearing was held on the proposal vn January 30, 2002. 8. T'he requirements for public notice of heating were met. 9. The Caunty Divisian of Flarming issued a L]etenninativn afNonsignificance (3NS) far the praposal on .Tanuary 11, 2002. HE Findings, Conclusions and Decision PE-189g-01 Page 1 • ' 17. The site and surraunding land are designated in the T7zban category of the Cavnty Generalized Comprehensive Plan. The subaect property and nearhy larad are alstr lacated in the Aquifer Sensitive Area, the Privrity Sewer Service Area and the TJrban Immpact Area designated by the PIan. i$. The site and sturoundirtg Iand are lacated inside the interirn urban growth area (TU~'rA) boundaries designated by tlze Caunty puz`ssuant to the State Growth 1Vlanagement Act. 13. The land surrounding the site primarily cvnsists of single-famiYy homes and scattered pockets of vacant land on parcels of°ane (1) acre in size ar less. The lats direcctly abutting the site range in size fram approximately 9,600 sguare feet tv 26,700 squa,re feet, with rnost abutting Ivts ranging from 13,500 square feet to 18,000 squa.re feet an size. The land abutting the saufi.h side of Eighth Avenue directly south of the site consists of a twa (2) acre parcel and 1.4-acre parcel, vvhich are undevelaped. Smaller lvt sizes mare sirnilar to the project are found west of Bovvdish and naz`th of Sixth Avenue in the vicinity. 20. The County Arterial Raad Flan designates both Eighth Avenue and Bawdish Road in the area as Minvr Arterials. The intersection of sueh rtaads is contralled-by stvp signs on Eighth Avenue. T'he Cvunty plains ta widen Bowdish Road, befween Eighth Avenue and 32d Avenue to ttie sauth, to a three (3)-Iane arterial raad section in 2004. 21. The vnly opposatian to the greliminary pYat was submitted by the Qwners of three (3) single- family residential lots located near ar adjacent to the site to the eastlnortheast, alang the south sid.e of Sixth Auetaue; aind by the vwners of a single-family residentiallot of approximately .75 acres lacated directly svutheast vfthe site, across Eighth Avenue. See parcel informaticrn in public natice documents, and zaning map attached tv staff report. 22. The abaVe-referenced apponents contend'ed that the density and 1ot sizes far the proposal were incansistent vuith the semi-niral character of the neighborhood, the proposal wouYd negatively impact vvildlife frequenting the site, the proposal cvuld negatively iEnpact schvol capacity at pubYic schovls serving tha prapasal, that a traffic signal at khe intersectian of Bowdish Road anti Eighth Avenue needed to be installed ta reduce congestian and improve haffic safeiy, that Bowdish Road should be widened betvveen Eigttth Avenue and Sprague AVenue, that Eighth AVenue shvuld he widened east of Brawdish Rvad before apprvvai of t.he praject, that the lack of sidewalks along Eighth Avenue created a safety hazard to pedestrians, fhat appraval of the praject would establish a precedent for sirnilar diVisians of land in the vicinity, aad vther cancems. 23. The local public schaol district was contacted regarding the project, but did not subrnit any camments. Pr4ject apponents did not submit anny cQmpetent informatian indicating that tF~ie prvject would significantly imgact school capacity En the district. _ , HE Findings, Canclusivns and Decisian PE-1$99-01 Page 3 ' 33. The prvpvsal easily corraplies with the recomraiended residential net densiky range in the d..lgban category of 1-17 dwelling unyts per acre. Ilecision Guideline 1. 1. 2 indicates that base net density for single-famiTy dwelling au'eas rnay be increased thxough bonus densiYies when meeting the "fill-in" ctiteria. While the applieant has nQt requested bernus density for the praject, the praposa1 nevertheless meets the definition o#' "fill-in development" contained in the glossary of the Comprehensive Plan, since it is located between and Qn reasanahly clcrse proximity to at least twv (2) existing develaped geagraphic areas, tv the svutheast and northwest, having densities and la.nd uses which canform to thhe iJrban categorry, and would aid in the economic suppart of public service systems Ysy increasing the cost-effectiVetaess of utilataes and public servzces and facilities. 34. The LTrban categ+ary does nat recomrnend the need for public transit, ar location alang 2ua arterial, to serve single-family developments with the residential density of the eurrent praposal. See Decision 'uuideline 1.1.3. 35. Considering such factvrs as the UR-3.5 zoning of the site arid adjacent properties, the high level of urban services available ta the praject, the lvcation of the site a2ang a Minar Arterial, the access to lots provided by the interna1 publ'rc roads in fhe prvposal, and the minamal nurnher 4f lats (1-2) in the propasal abuttang any Yots on adjoining praperkies, the design, shape, size and ❑rientation of the lvts in the preliminary plat are apprapriate for the residential uses prapased ira the subdivision, and tie character of the area. 36. The State Grvwth Management Act encvurages higher residential densities inside urhan grawth borandaries. With the extensivn of public sevver to the area, and designatxon of the area inside the County's TC7GA baundaries, land use trends in the area have been taward higher residential densitaes. 37. The Exavniner concurs in, and adupts by reference as findings of fact hereira, the analysis contained in the Staff Repvrt regarding the consistency of the proposal with the Comprehensive Plan and the deVelapment st.andards of the UL-3.5 zone. 3$. No deficiencnes with regard tv the pr-ogvsal's compliance with develapment regulations have }aeen estahlished in the record. 39. No public agencies objected to the praposal, as conditioned, ar its enviranmental impact. Tlae project wi11 not have more than a mvderate effect an the q,uality of the environment. 44. As cvnditivned, the project ►avill be rea.sonably cornpatible vvith neighhoring land uses, and will not adverseTy irnpact the puhlic health, safety and general welfare. 41. `I"he proposal has been canditrone+d fnr compliance with the UR-3.5 zone, the CQunty Zoning Code, the Caunty Subdivision Ordanance and other applicable development regulations. 42. []n January 15, 2002, the Cvuaity atiopted a new camprehensive plan and phase r development regulafiens, to implement the State Growth Management Act. See Couniy Resolutian No. 2-0037.

Aleffi Subdivisican This computation is for the stormwater conditian as designed. 1t shaws that the design velocity far the pipe furthest up in the reach (12" diarrieter N12 pipe, 115 feet in length) is 1.61 feet par second. The flaw rate rs restricted because of the superentical candition with the calculated flows for a i 0-ycar evcnt. This scenaria was selected because it aptimizes flow capacity with Iaw Anstallalion eost compared to ofiher piping alternatives. A piping alfemative was selected despite being higher cost because it protects the existing home frontages as much as is practical. A draanage Ghannel would intraduce a"canyon effect" alang the frantages, which is unsafe and aesthetically undesireable.

The problem that we found was that the builder had relocated the designed driveway to the west of the low point and had not constructed it per plan. It was 0.15' too high which caused additional ponding in the swale in question. The second problem that we found was that the sod was installed and has grown up about 1-2" over the top of tYie concrete which is causing some additional "damming" effect. We responded to Colleen's email and asked her to contact us if she had any additional questions. Since she didn't contact us, we assumed that our response had satisfied her questions. We don't have anything from her after we sent our email. The other question that we have discussed with John is if the swale is actually not functioning. I have been out on site at least twice after fairly significant storms and no water was in the swale. If it is draining in a 72 hour period, then I would say it is functioning as designed. Some homeowners may not realize that this is the case. I don't know for this swale but it was just an observation. We are meeting with the builder tomorrow to review possible options. One would be to remove the driveway and replace it at the design grades. The other option that we had discussed was installing a small "drywell" in the low point swale. This would be similar to drywells that are installed during County sewer projects in areas that don't have much room. We envision this to be a 12" perforated pipe installed vertically with a round grated lid on top. The rim would be 6" above the bottom of the swale so there would still be a pond, but it would not be as deep as it currently has to be to get past the driveway. Let me know your thoughts on this. We are meeting at 1:00 pm tomonow. -----Original Message----- From: Gloria Mantr [mailto:gmantz@spokanevalley.org] Sent: Wednesday, July 19, 2006 4:00 PM To: Jeffrey N.

It appeazs by looking at the cul-de-sac plan view (Sheet 3/5) that the swale in question is at a low point and does not have an overflow facility (i.e. a drywell). I noticed that a drywell was proposed and constructed across the street at STA 10+37.67, but not where we have the problem. 7/20/2006 ~ _ - - ~ Page 2 of 4 A1sQ, Z see an e-mail from Colleen askixig Lisa Frcy some questians.

ICen asked that I forward yau Enfarmation regartiing A1effi as it relates to Alysa's message, Items #2, 3, &4 seem straight forward but of special interest is item #1. We addressed this during the cvnstruction phase with Randy and CQlleen T.,ittle. Basically, the contractar relocated several driveways and anade them wider thar► we had designed. We checked the basin calculations to accaunt For the actual sizc arzd Pocation built arad prowided azpdated spreadsheets to Colleen. Z've attached this correspondence and the associated spreadsheet for yaur review. Regarding tlhe law partion of fhe swale. The taw paint on the inlet is 2006.56'. The driueway to the west has a TOC elevativn iloted an the design of 2007.36. The drivevvay detail (#714) an Sheet 4 af 5sh4ws the design af the feiture driveway constructian. In this detail, the driveway was to be cQnsfnacted wAth a"uaIley" which allows drainage ropass acsoss. This "valley" was designed to be 0_9' below the top af curla elevation. The "valley" flow design elevatiQn wauld therefore be 2006.46' Dr 0.9' lower. Tus means that the water eleuation as it went aver the drivevvay wvuld be 0.1 ° belaw tlle curb inlet. This wauld allaw vvater with an elevation higher than 2006.46' to cantinue to the drywell located in front of lot 4 further to the west. The phota (7th & VVilbur Ct Add l jpg) that Aflysa attached and I've included via cc, shows that this apgeawrs to be what is happening. The water ponds in the swale but is n4t on the road. The nature af these continuaus swales is that there wi11 be ponding between driveways up to 6" deep 7124120Qfi ~ • - - Page 3 of 4 so wauld not be a surprise after a storm eVent (especially some of the storrb-As we haVe had this yeart). The questivn vvould be how quickly after the starm the ponds went away. Zf #hey vNere gone after 72 hours, then I think they would be cansidered t4 be operatim~ as designed. When Ken and [ took a lovk at the project site la.st week, it loaked like the swales may not haE=e been landscaped respectirng the swa1e design. They 1QOked a 1itt1e shallower than design and the grass was ug arrd over the cortcrete at the driveways. This grass could cause a "damming" effect as water tries tQ flaw acrvss the driveways whieh cvuld cause scrme localized pvnding nn the driveways. in addition, we couldn't tell with our naked eye if the driveway's were eanstnacted in accordance with the detail. Dn this prraject, these were installed aftec the raadway canst,riaction and dpprvval sv were cQmgleted by the huilder. Ken and I are going to check these eleuatians an WednesdaY- Ifewerything checks ouf (ponds are d~ep enough; driveways are build correctly, ponds dtain in 72 howrs) then we could ga and rneet rA+ith the homeovwner to try and revieGw the stormwater design strategy.

Ken asked that I forward you information regarding Aleffi as it relates to Alysa's message. Items #2, 3, & 4 seem straight forward but of special interest is item # 1. We addressed this during the construction phase with Randy and Colleen Little. Basically, the contractor relocated several driveways and made them wider than we had designed. We checked the basin calculations to account for the actual size and location built and provided updated spreadsheets to Colleen. I've attached this correspondence and the associated spreadsheet for your review. Regarding the low portion of the swale. The low point on the inlet is 2006.56'. The driveway to the west has a TOC elevation noted on the design of 2007.36. The driveway detail (#7/4) on Sheet 4 of 5 shows the design of the future driveway construction. In this detail, the driveway was to be constructed with a"valley" which allows drainage to pass across. This "valley" was designed to be 0.9' below the top of curb elevation. The "valley" flow design elevation would therefore be 2006.46' or 0.9' lower. This means that the water elevation as it went over the driveway would be 0.1' below the curb inlet. This would allow water with an elevation higher than 2006.46' to continue to the drywell located in front of lot 4 further to the west. The photo (7th & Wilbur Ct Add l.jpg) that Alysa attached and I've included via cc, shows that this appears to be what is happening. The water ponds in the swale but is not on the road. The nature of these continuous swales is that there will be ponding between driveways up to 6" deep so would not be a surprise after a storm event (especially some of the storms we have had this year!). The yuestion would be how quicl:ly after the storm the ponds went away. If they were gone after 72 hours, then I think they would be considered to be operating as designed. When Ken and I took a look at the project site last week, it looked like the swales may not have been landscaped respecting the swale design. They looked a little shallower than design and the grass was up and over the concrete at the driveways. This grass could cause a"damming" effect as water tries to flow across the driveways which could cause some localized ponding in the driveways. In addition, we couldn't tell with our naked eye if the driveway's were constructed in accordance with the detail. On this 7/20/2006 Page 2 of 3 , • praject, these were instailed after the roadway construction and apprQUal sa were campleted by the huilder. Ken and I are gaing to check tnese elevativns on Wednesday. If everything cfiecks out (ponds are deep enough; driveways ar'e build cortectly, ponds drain in 72 hours) then we could go and meet with the homeowner to try and review the storrnwater design strategy. 1f there are elevational pcoblems with the swrales andlar driveways, then T diink that Ken was gQing to meet with the builder to discuss remedies. If the pvnd doesn't d.rain vvithin 72 hours, the gass cauld be ralled back and the soil cauld tae amended ar the soil could be aerated to see if the situaticrn improves.

The Hearing Examiner takes natice of t.lie County Corriprehensive Plan, County Arterial Road Plan maps, Cvunty afficial zoning tnaps, Caunty Zoning Code, County Cade, aher applieable development regulativns, and prior latzd use decisians in the vicinity. 12. 'I'he recard includes the dacunents in the praject file at the time of the public h"g, the docurnents and testirnony suhmit#ed at the public hearing, aaid the itezns #aken notiee of by the Hearing Examiner. 13. The site is 4.27 acres rn size, substantially square in shape, relatively flat in topo graphy and slapes graduaTly dawn frvr~ n~orth to south. The site is made up of two par+~eps, each ~o (2) acres in size. Three (3) single,family humes are faund in the soutneast crarner of the site, frbnting along Lighth Avenue. Such hamesites vvere apparently constructeti withaut a legal divisivn of land. A nvn-sight obscuring fence surrvunds t.he sub~ect propemy. The undeveloped pvrtion af the site conkains same waod debris a.ndjunk bxems. 14. "I'he prelirninary plat rnap of recvrd was submitted on NvVember 28, 2001. The rnap illustrates divisian of 4.27 acres of land ~into 14 single-family residentiallats, vvhich 16 wvuld range froxn 10,409 syuare feet to 13,843 square feet in size. The existing residences ruld remain on proposed I,vts 12-14 af the preliminary plat. Such 1ots, tagether wi#ta Lat 1 af the preliminary plat, would directly access Eighth Avenue. The remaining lats wauld directly access ~the internal public roads in the preliminary plat, which r+aads respectively cuY-de-sac at the noxtkt and east boundaries af the site. The {net} density af the prelimuaary pTat is ~'vur (4) dwelling units per acre. 15. The site and suri'ounding, land are zarred Urbata Residential-3.5 (UR-3.5). The 1UR-3.5 zane permits a(net) density of 4.35 dwelling ~wiits per acre. 16. and the Public Transit. ene ea esigna e y e vunty Zvning Code. HE Findings, Conclusions and Decision - PE-1899-01 pa~e 2 , ` - ~ - 17. The site and surrvunding land are designated in the Urban ca#egory of the County Cieneralizeci Cvrnprehensive P1an. The subject property and nearhy Yand are also lacateti in the Aquifer Sensitive Area, the PrivriEy Sewer Set`vice Area and the Urban Inpact Aaea designated by the Plan. 18. The site and sturounding 1and are lacated inside the interim urban gmwth area (ITJGA) baundaries designated by the County pwrsuant to the State ~'rraruth Managernent Act. 19. The laiad surrounding the site primarily cansis#s of single-family hames and scattered pockets of vacant land an pa.rcets of one (1) acre in size or less. "The lots directly abutting the site range in size from approximately 9,600 square feet to 26,700 square feet, vvith most abutting lots ranging frarn 13,500 square feet to 18,000 squaxe feet an size. The rand abutEing the saukh side of Eighth Avenue directly south of the site cansists of a twn (2) acre parcel and 1.4-acre parcel, which are undeveloped. 5ma11er 1at si2es more sirnilar to the project are found west of Bowdish and north of Sixth Avenue in the vicinity. 20, TYae County Arterial Rvad Plan designates both Eighth AVenue and Snwdish Roasi rn the area as Minvr Arterials. The interseGtion of such raads is contralled=by stvp signs on Eighth Adenue. The Count}+ plans to widen Eovvdish Ttvad, befween Eighth Avenue and 32ad Avenue tv the south, to a three (3)-lane arterial mad section in 2004. 21. The only opposition to the preliminary plat vvas submitted by the owners of three (3) single- family residentiallvts located near ar adjacent ta the site to the eastlnortheast, aPong the south side of Sixth Avenue; atad hy the owners of asingle-family residenfiallot of appxaxirnately .75 acres located directly svutheast of the site, across Eighth Avenue. 5ee pap.rcel in.farrnatiQn in puhYic notice dncunents, and zoning map attached t❑ staff report. 22. The abave-referenced appvnents cantended that the density and lat sizes £ar the propc+sal vvere incvnsistent with the semi-rural Gharacter of the neighborhood, the prapasal would negatively impact wildlife frrequenting the site, the proposal cauld negatiuely irripact schoal capacity at public schools serving the proposal, that a traffic signai at the intersection of Bawdish k4ati and Eighth Avenue needed tv be installed tca reduce cvngestion and improve traffac safety, that Bvwdish Road should be vvidened befween Eighth Avenue arad Sprague Avenue, that Eighth Avenue should be vvidenei east of Bowdish Road befgre approvai of the project, that the lack of srdewalks aiang Eighth Avenue created a safety hazard ta pedestriaris, that approval of the prvject would establish a precedent fnr sirnilar divisians of larsd in the vicinity, and other concerns. 23. The lacal publre school district was ccantacted regarding the project, but dxd not submit any camments_ Project opponents did nat subm$t any competent information indicating that the project would significantYy ianpact schvvl capacity in the district. 24.p~ , HE Fintlings, Conclusians and Decisian PE-I899-01 Page 3 f 25. Project vpponents did not submit any evidence that EigTith Avenue is used'by students whv walk only ta schQOl, nvr was evidence of a traffic engineering nature submitted indicating that any such students would be endangered by traffic from the project ifEighth Avenue was widened onTy alang the frantage of the sire. Additional improvements to Eighth Avenue may acceir as t,he parger lats along such road behaveen Bowdish Road and Pines Road are divided consistent with the underlying UR-3.5 zorung. 26. No evidence of atraffic engineering nature was presented ta rebut the conditions of approval recommended by County Engineering for ths project; or establishing that further traff'ic mitigatian is needed alang Eighth Avenue, Bowdish Road narth of Eighth Avenue, vr at the intersectian of Eighth Avenue and Bowdish Road. The improvement of Bowdish Road svu#h of Eighth Avenue tv a 3-lane arterial road section will lvgically enhance traffic circulativn alang $vwdish Rvad svuth of Eighth Avenue, atzd also enhan~e turning mcavements at the intersection of Bvwdash Road and Eighth Avenue. The Examiner has na rativnal basis ta require traf'fic mitigativn in addition to that recarnmended by Cvunty Engineering. 27. Caunty Engineerirrg indicated that a full 16 Feet of right of way may not need to be reserved as a future right of vvay acquisikion area alvng Eighth Avenue, in vrder to i'rnplement the Cvurnty Artet-ial kvai P1an, depeMding on location of the centerline far Eighth Avenue. The Cnunty Enginsering and County Plaraning conditians of appraval that address the future acquisitian area have been revised by the Exarniner to allvw far a reducfiion in the £uture acquisitian area, if vvarrrranted. 28. T'here is no eWidence that the propasal will have a significant aduerse irrepact on park and recreation facilities in the azea. 29. County Gritical Areas maps da not designated priority vviTdlife habitat, or ather critical areas an the site. No campetent evidence was su6mitted that endangered species either frequent the site or vvauld be significantly impacted by the project. Under such circumstances, the Examiner has nfl basis to require mitagation for wiTdlife. 30. Cvunty Planning previousIy approved an administrative exception to a1Pow the rninirnurn tvt frontage for Lats 13 and 14 in the propasal ta be reduced from the 84=foot wide frontage reqnirement of the T1R-3.5 zone ta 75 feet. Zvning Cvde 14.506.420 speeif Gally authorizes a 1 D°/u deviatian in lot frantage requirenents, which the exception grantsd hy County Flanning conforms tv. 31. The existing detached garage serving the existing residence can Lvt 14 of the pr+apasal is located a few feet within the side yard setback required by tYie L7R-3.5 zone. This is an existing canditaon that is nof aff'ected by appraval of the preliminary plat. The adjvining property awrter to the east did nat object ta such pnssibYe encroacfiment, which may have been alegal encraachraaent at the time the garage was installed. 32. 'i'he Staff Repvrt sets farth applicable palicies of the Urban category, and the purpose and intent statement of the UR-3.5 zvne. As recommended by Decisivn Guidelaaae 1.1.2 of the CJrbara category, the propvsal will be served with adequate power supplies, water, sanitary sewer, drainaga facilities, roads, school and fire services. As recamanended by the UR-3.5 zone, the praposal wi11 be served with a high leve1 of public services. HE Findings, Conclusians and Decisian PE-1899-41 Fage 4 ' 33. The proposal easaly complies with the recommended residential net density range in the Llrban categv_ry of 1-17 dvvelling units per acre. Decision [suideline 1.1.2 indicates that base net density for single-family dwelling areas may be increased through bonus densities vr+hen rneeting the "fi11-in" criteria. While the applicant ha,s not requested bonus density for the groject, the proposal nevertheless meets the dcfinition vf "filY-in development" contained in t.he g1ossary of the Comprehensive P1an, since it is located between and in reasvnably clerse praximiiy to at least two (2) existing develvped gevgraphic areas, ta the svuthea.st and nmrthwest, having densities arid land uses which canform tv the Uarban category, and wauld aid in the eGOnornic suppart af public senaice systems by increasing the cost-effectiveness of utilities and public services and facilities. 34. The LJrban category dQes not recammend the need fvr public transit, or locativn along an arterial, ta serve single-faanily developments with the residential density of the current pt`aposal. See Decisign Guideline 1. 1.3. 35. Gansidering such factors as the [IR-3.5 zoning of the site and adjacent properties, the high level nf rzrban services available tfl the prnject, the tocatian vf the site alvng a Minar Arterial, the access to lvts grovided by the intemal public roads in the praposal, and the minimal nwnber of Iats (1-2) in tkie proposal ahutting any lats on adjvining proper[ies, the design, shape, size and arientaCion of the lots in the preliminary plat arre apprQpriate for the residentaarl uses prapased in the su'bdiVisi4n, and the character Qf t.he area. 36, The State Growth Management Act encourages higher residential densities inside urban growth baundaries. With the extensiQn af publiG sewer to the area, and designation af the area inside the Caunt}+'s ILJGA bawndaries, land use trends in the area hawe been toward higher residential densities. 37. The Examiner concurs in, and adapts lay reference as findings of fact herein, the analysis cvrctained in the Staff Repart regarding t.he consistency of the proposal with the Comprehensive Flan and the deuelapment standards of the UR-3.5 zone. 3$. Nv deficienCies with regard to the propasal's compliance with develvpment regulations have been established ira the recard. 39. No pubiic agencies objected to the prnposai, as conditioned, or its environmentak impact. The project vviIl nvt have more than a znoderate effect an the qua,lity af the environment. 40. As c4ndptioned, the project will be reasanably compatible with neigYaboring land uses, and will nat adversely impact the public health, safety and general welfare. 41. The proposal has been canditiaraed for compliance with the L]R-3.5 zone, the County Zoning Code, the Gvunty SubdivisiQn Ordinance and ather applicable develapment regulativns. 42. 4n lanuary 15, 2402, the County adopted a new comprehensive p1an and phase T development regulaticrns, tv implement the State +Growth IVlanagement Act. See County Resolution No. 2-0037. HE Findings, Conclusions and Decisivn PE-1899-01 Page 5 43.

Iterns #2, 3, Bc 4 seem straight forward but af speGial inYerest is itern # l. We addressed Yhis during the r.orstruction phase with Randy and Colleen Gittle_ Basieally, the contractar relocated seweral driveways and made them wider than we had designed. Vu`e checlced the basin calculations to account far the actual size and locatiun hualt and prouided ugdated spreadsheets to Co1'leen. T've attached this carrespondence and the a.ssociated spreadsheet For yaur review. Regarding the low gortion of the swale. The tow point on the inlet is 2006.56'. The driveway to the west has a T0C elevatian noted on the design vf 2007.35. The driveway detail (97J4) nn Sheet 4 of 5 shows the design nf the future drivetiuay construction. Tn this detaail, the dn'vewjay was to be canstructed with a "va11ey" ,whiGh aEQws drainage tn pass across. T#us "valley" was designed to be 0.9' below the tap of curb elevatian, The "valley„ flaw design elevation wauld therefore be 2006.46' or 0.9' lovver. This r~eans that the water elevation as it went over the drivewvay wvuld be d.l' be1'ow the curb izilet. This would allaw vvater with an elevativn higher thar~ 2006.46" t4 Gvntinue to the drywe111ocated in front of lut 4 further fa the west. The photo (7th & Wilbur Ct Add l jPg) ihat A1ysa attached and I've included via cc, shows that this appears tQ be what is happening_ T°he water ponds in the swale but is not on fihe rvad. The nature of these cantanuous swales is that there will be ponding betweera driveways up to 6" deep so wmuldl not be a saarprise after a starna event (especially snrne 4f the stomns we have had this yeax!)- The questaon would be haw quickly after the stvrrra the ponds went away. Tf they were gane after 72 haurs, khen I tharak they would be considered to be operating as designed. Whhen Keri and I taak a l~ok at the project site last week, it lovked like the swales may nat have been landscaped respectang rhe swale design. They looked a little shallower than desagn and the gra~s was up and ~~er the conccete at the driveways. This grasss could cause a"damming" effecf as water firies to flow acrvss the driveways which cauld cause some loca~ized pnnding in the driVeways. In additiQn, we couldn't tell with our naked eye if the driveway's were canstructed in acr-ordance with the detaiL C)n this 711912OaG Page 2 of 3 praject, these were installed after the roadway constraction and appravai so were completed hy the builder. Ken and I are going to check these elevativns on Wednesday. If everyffiing checks out {ponds are deep enough; driveways are build correctly; ponds drain in 72 hours} then we could go and aneet witFa the homeowner to try and review the starmwater desig-n strategy. If there are e1evationa1 problems with the sufales ancllor draveways, then I think that Ken was going to meet with the builder to discuss remetiies. If fihe pond doesn't drain within 72 hours, the grass could be rolled back and the sQil could be amended vr the sDil cvuld be aerated to see if the situativn impraves.

Ken asked that I forward ycau infarmation regarding Ale ffi as it relates to Alysa's message. Items #2, 3, & 4 seern straight forward but of special interest is item #1. We addressedl this during the cnnstructiQn phase "ith Randy and Colieen Lattle. Basica11y, the cantractor relocated several driwevvays and made them wider than we hal designed. We checked d.he basin calculatinns to account for ihe a.ctual size and lacatiun built and prcrvided updated spreadsheets to Co1leen. I've attached this correspondence and the associated spreac3.sheet for your review. Regarding the law porti4n af the swale. T'he Zow paimt on the inlet is 200+6.55'- The driveway to the west has a TQC eleuativn nQted on the design mf 2007.36. The driVeway detail (014) arr 5heet 4 af S shaws ttae design af t.he fuiure driveway canstruction. Tn this detail, the driveway was to be canstructe:d with a"valley„ which allaws drainage to pass acrflss. `Ihis "aalley" vvas designed to be 4.9' belavv the tog of curb eleva#ivn. The "valley„ flow design elevatiran would therefore be 2006.46' or 0.9' lovaer. This means tYrrat the water elevation as it went over the driueway would he 0.1' belaw the curb inlet. This v►rould allaw water wvith an elevataon higher than 2046.46' to Gtantin,ue to the drywell lacated in frant of Iot 4further to the west. The photo (7$h & VVilbur Ct Add 1 jpg) that Aflysa attached and I've included via cc, shaws that this appears to be what is happening. The water prands in the swale but is not Qn the road. The nature of these cantinuaus swales is that there will be ponding between driveways up to 6" deep sa wauld not be a saxrprise after a storm event (especially sorne of the stornns we ttave had this yyearf). The questinn would he haw quickly after the storm the pvnds went away_ If they vveree gane after 72 hours, then I think they would be considered to be operating as d'esigned. When Ken and I took a 1ovk at the project site lasi week, ifi loaked like the swaales may not have been laradscaped respeeting the swa1e design. They looked alittle shallower than design and the grass was up and over the concrete at the driveways. This grass could cause a"daanming" efFeet as water tries to flovv across the drivevvays which cnuld cause same loca.lized panding in the driveways. In addition, we couldn't tell with our naked eye if the driveway's were constructed in acccordance with the defiail. C?n this 7f 1 9!200G , • r,-- ~ Page 2 of 3 project, these were installed after the roadway coaastruction and approval so were completed by the huilder. Ken and T are going ta cheek these eievatians on Wedraesday. If everythin,g checks out (ponds are deep enough; driVevvays are build correctiy; ponds drain in 72 hQUrs) then we cQUId go arid meet wi[h the homeowmer to try and review tfie stvrmwvater design strategy. If there are elevational prnbienis with the swales and]or driveways, then I think that Ken was gving to meet with the buulder to discuss remedies. If the Xsand daesn't drain widvrl 72 haurs, the grass could be rolled back and the soil could be amended or the svil cou1d be aerated fio see if the situation ianproves_ I'an sure there are oxher salutions also.

K.en asked that I farward yau infozmation regardyng AIeffi as it relates to A1yas message. Ttems #2, & 4 seerm straight forward but of sgecial interest is item #1. We addressed fihis durin~ the canstruction phase wit11 Randy and Calleen LittPe. Basically, the contractor relocated severa1 driveways and made them wAd'er than we had designed. We checked the basin calculatia~ to accaunt for the actual size and locatian built and prouided updated spreacisheets to Calleen. I'ue attarched this correspandence and the assocxated spreadsheet for woEU° review. Regarding the low portion of the swale. The lavv point on the inlet is 2406_56'_ The drivevvay to ihe west has a TOC elevatian noied on the design of 2047.36. The driveway detail (47f4) on Sheet 4 af 5 shovvs the design of the future daaveway cvnstructian. In this detail, the drivewFay was to be constructed with a"valley„ which allows dTainage to pass acrcrss. This "valley" was designeci fia be 0.9' be1ow the tvp of curb elevation. 'Yhe "valley„ flaw design e'levatican would therefore be 2006.46' or 0_9° lowes. Tfi.is mearas that the water +elevatirn as it went c►ver the driveway would be O.1' below the curkt inPet. T'his woruld allow water Arita an elevatian higher than 2006.46' to continue to the drywell located in frant of lot 4 furtherr to the west. The phnto (7th & 'VG'albur Ct Add 1 jpg) that Alysa attached and I've included via cc, shows tttat this appears to be what is happening. The water pands in the swale but is not mn the mad. The nafiure af t.hese continuaus swales is tlaat there wiI1 be pcanding between driveways up to 6" deeg so would not be a surprise after a starm event (especially some of the storms we have had this yearr). The questivn would be hova quickly after the starin the ponds went away. If they were gane after 72 hours, then Ithink they woui'd be considered to be operatisig as designed. When Ken and I iook a dcaok at the project site last week, st looked like the srvales may not have heen landscaped respecting the swvale design. Tl-iey looked albttle shallower tha.n design ancl the grass was up arrd over the concrete at ihe driveways. This grass could cause a"damming'° effect as water tries to flow across ihe drave+avays which cauld cause some locaiized panding in the drivew+ays. In ad'dition, we cvuldn'f tell with our naked eye if the driVeway's were constructec4 in accordance with the detail. C3n this "11I91200f . • - Page 2 of 3 projecL these were installed after the roadway constraction and approval so were completeti by the builder. Ken and I are going to check these elevationns on Wednesday. Tf everyffiing checks out (ponds are deep envugh; draueways are build correctly; ponds drain in 72 houas) then we could go and meet with the homeowner to try and review the stormvvaker desigm strategy. If there are elevational problems with the sv►+ates andlQr dri►reways~ then T think that Ken was going to meet wrth the builder to discus~ remedies. If the pond daesn't drain within 72 hvurs, the gass could be rolled back and the soil r„ould be amended or the svil cvuld be aerated to see ~f the situation improVes. 1'rn sure there are ofiher solutivns also. We'l1 let you lcnaw what vve find out.

We'll revise the hydraflow report to reflect that the downstream invert for the lowest pipe, the 54, length on the east side of Wilbur Court, is 2011.9. This yields a slope of 0.9% (actually 0.00926) The other slopes shown on the report for pipes 2 and 3 of 0.53% and 0.52% are allowances for rounding on the slopes shown on the plans of 0.50W.

We recently received the $30 design fee for the pipe velocity design deviation, so I have been reviewing the information that was submitted with the design deviation. I have a couple of comments that need to be addressed before the design deviation can be routed through for staff review: l. The pipe network analysis results indicate that all the pipe velocities are less than the 4 fps minimum requirement, so the design deviation needs to discuss all of the pipes, not just the 1.61 fps velocity pipe. 2. It appears that the pipe slopes in the pipe network analysis for the design condition do not correlate with the pipe slopes shown on the plans. Please look into these issues and provide any necessary updated materials. Thank you, Cindy Cindy D. Callan, P.E.

The following items stili need to be addressed or resalVed prfor to aGCeptance of the plans: 1. A pipe network analysis needs to be subanitted. It is our understanding that prelimmaty pipe netwark analysis resu[ts indicate avelociiy of less than the 4 fps rrummum. A design deviation needs to be subrnitted far any pipe segment that does not meet the minamum requixernent. 2. The design deviation that was submitted on July 26, 2402 for the 50-ft crest vertical curve crn Wilbur Court is not necessary. The SO-ft crest Vertical curve meets the requirements of the Steandards; therefore, the design deviation has been voided. Hovvever, the praposed 100-ft sag vertical curve on Wilbur C6urt does not meet the requaremecits of the Stcrndrzrds. As discussed in yaur phone conversatiQn with Jahn Hahman on August 28, 2002, the uertical curve must he updated to meet the Standards because fi.he Caunty dQes not accept desggn deViatYOns for nanconfarnning uertacal curves on nevv roadways. Thank you far your attentlon to these issues. If you have any questions about this review, please contact Cindy Ca11an at 477-3600. Sincerely, .Tohn V. Hohman, P.E.

During our phone conversation today, you requested that I send you a written explanation as to why a taper is required at the entrance of the road widening of 8th Avenue. As I explained on the phone, Spokane County requires tapers at the bcginning and end of roadway widening projects for safety and because it is good engineering practice. Without a taper, the junction where the widened width begins can be compromiscd, which will likely result in a pothole at the junction. The County Traffic Engineer recommends a minimum 100 ft taper at the beginnmg of the road widening; however, a lesser length may be allowed if there is madequate right-of-way available at the site. If you have further questions regarding this issue please contact John Hohman at 477-3600. Thanks, Cindy Cindy D. Callan, P.E.

I made all changes the county had for this project, with exception of the pavement transition, so I don't imagine it should take too long to approve. What is the status of the deviation? The Owner asked if we could have approved plans by August 15? Can you please let me know if there is something I need to follow-up on, so I can take care of it right away? I would appreciate it greatly. I will also be going on vacation on the 14th, so if you could let me know today (Monday), that would be great.

Howard Spokane, WA 99201 Subject: P1899 - Aleffi Addition (8'h & Bowdish) Road and Drainage Submittal #1 Dear Alan, We reviewed your June 19, 2002 submittal of the design documents for this project. The following items need to be addressed or resolved prior to acceptance of the plans: 1. The sewer plans need to be subrmtted to the Uhlities Department in a separate submittal under a separate cover sheet. Please remove the water and sewer sheets from the road and drainage plans. You are welcome to include the water and sewer sheets as reference information in the road and drainage submittal package. 2. A Design Deviation needs to be submitted for the design elements that do not meet the Standards for Road and Sewer Construction for the road widening of 8`b Avenue. 3. The geotechnical report needs to include the test pit reports and a figure showing the test pit locations. 4. Please verify that the correct roadway pavement section was selected from the local access matrix for type GM soils. 5. It appears that one of the vertical curves is inadequate. Please verify that all the vertical curves meet the minimum requirements in the Standards. 6. Right and left curb roadway profiles need to be provided on the plans. 7. A pavement taper needs to be provided along 8`b Avenue at the entrance of the project. Typically, a minimum taper length of 100 feet is required if there is adequate right-of-way. 8. Please provide a detail that shows the transition from the end of the proposed curb to the existing pavement. 9. A remforced concrete sidewalk section needs to be located adjacent to the drywell on 8h Avenue for maintenance access purposes. A detail of the reinforced sidewalk needs to be shown on the plans. 10. Please verify that the curve data for the intersection curb returns is shown on the plans. 11. The benchmark for this project needs to reference an established NAVD 88 benchmark. 12. Please verify that a station equation for the intersection of 7`h and Wilbur has been provided. 1026 W.

Standard Note #9 from Appendix B of the Guidelines for Stormwater Management needs to be included in the Standard Notes for this project. 15. Either a standard drawing needs to be referenced or a detail needs to be provided for each structure, such as drywells and inlets, on the plans. 16. Riprap needs to be provided at the outlet of the pipe system. The proposed concrete pad protects the slope, but does not provide energy dissiparion for the runoff. Please include nprap calculahons that correspond with the riprap design. 17. An irrigation system is required for publicly maintained swales and ponds. Please provide information regarding the irrigation system on the plans. At a mmimum, a note needs to be included in the General Construction Notes. 18. The plans need to be signed by the developer for each submittal. 19. The time-of-concentration routes need to be shown on the basm map. 20. A pipe network analysis needs to be submitted. Please verify that the peak velocity in the pipe is at least 4 fps for the design storm flow. Also, there must be at least 0.75 feet of clearance from the grate elevation to the hydraulic grade lme. 21. Non-flooded road width calculations need to be submitted. (Figure 37 in the Guidelines.)

Wyatt Engineering • 1220 N. Howard Spokane, WA 99201 Subject: P1899 - 8h & Bowdish Clarification of Pre-design Meeting Issues Dear Brian, There were several outstanding issues at the conclusion of our pre-design meeting on March 14, 2002. I spoke with the appropriate people about these issues, and the following are the decisions regarding these issues: 1. 8`h Avenue right-of-way (ROW): At the meeting, Brian brought information and figures that showed 8`h Avenue was built north of the ROW centerline. Brian made the case that with respect to the ROW centerline the road improvements already exist, so no road improvements would be needed for this project. According to the County Tra.ffic Engineer, Bob Brueggeman, 8Ih Avenue was not constructed at the centerline of the ROW along the entire stretch of roadway from Bowdish to Pines. In order to provide the roadway section that is required for a 3-lane minor arterial, while trying to protect existing houses, he decided that the 4 feet of addrtional ROW specified in the Conditions of Approval still needs to be granted from this plat and the roadway needs to be centered in the resulting 54 feet of ROW (50 ft existing plus 4 ft new). The roadway section for a 3-lane minor arterial is 50 feet, back of curb to back of curb, so the roadway improvements for this plat would begin with a curb 2 feet inside the new 54 feet of ROW and include the asphalt necessary to improve the roadway from the curb to the existing roadway. Bob also said the taper from the roadway improvements needs to extend from the plat west to the Bowdish intersection. In addition, separated sidewalk is required along 8~' Avenue, which needs to be placed in a border easement. 2. Sidewalks along Wilbur Road and 7"' Court: Based on the proposed roadway alignment of Wilbur Road and 7th Court, Brian showed the roadway section wrtb no sidewalks because each length of road is individually less than 400 feet. According to the Standards, "sidewalk will not be required on cul-de-sac roads less than 400 feet in length." It is the consensus of our group that these roads do not meet the conditions because the alignment shows one continuous roadway with one cul-de-sac. Therefore, separated sidewalk is required on both sides of both roads. 3. Fire district approval: The current roadway configuration is acceptable with the condition that it receives fire district approval. I e-mailed the fire district approval form to Brian today. Please fill in the appropriate project information, give this form to the fire district and request that they specifically state that the roadway alignment is acceptable. 1026 W.

Brian made the case tFiat with respect to the ROW centerline t'he road imprQUements ali'eady exist, so na road unprovements would be ~ needEd for this project. Accarding Co the County Traffic Engineer, Bob $aueggeman, 8" Avenue was not consCructed at the centerf zne af #.he ROW along the entire stretch of roalrvay from a Bowdish to Pines In order to pravide the Paadway section that xs requued for a 3-lane minor i~ ~ artenal, whuIe trying to protect exfsting houses, he decided that the 4 feet of addiCicsnal RdW vk~ specified Ln the Gonditions of Approual still needs ta be granted fi-om this plat and the rvadway ~ nceds ta be centered in ~s re.sulting 54 £eet af RO'L~ (50 ft exisCing plus 4 ft new). The roadway sectinn far a 3-lane minor arterial is 50 feet, back af curb ta back Qf curb, so the roadway ~ smpraversaents for this plat would begm with a curb 2 feet inside the new 54 feet o£ RC]VV and include the asphalt necessary ta irrsprove the roadway fr6rn the curb tQ the existing roadway. Bab so said ihe taper frvm the roadway improwemen[s needs to extend from the plat west to the Bowdish intersect,ian. In additian, separated sidewalk is required alnng 8"' Avenue, wTuch needs to 6e placed in a border easemenC, 2. SidewalTs along Wi1bur Road and 7~'' Court: Based nn the propased roadway alignment of Wil6ur Road and 'l" Caurt, Sn2ata Shotived the raadway seefiion with no SiClewa19s because each ~ length o€ road is individualiy Iess than 404 feet. Acc~arding ta the Standards, "si~tewallc wx1I noC ~ be required on cul-de-sac raads less than 400 feet zn length " It is #.he consensus a£ our group that these raads do raot meet the conditions because the alignment shows one continuaus roadway with one cul-de-sac. Therefare, separated sidewaPk is required on both sides of both roads. ~ 3 Fire district approval: The current roadway configuraiion is acceptable with the cvnditlon that it receives fite distnct appraval. I e-rnailed the ~'ire district approvai fQrm to Bnan today. Please T . f ll m the appropriate prvject gnfvrmation, give this form #o the fire distract and requesC flaaai they sgecificaliy state that the roadway aiigaiment is acceptable. ~ 1026 W.

Please be aware that if the original roadway alignment wif,h the two cul-de-sacs is used for tlus project, Che cul-de-sacs need ta he burlt carnpletely witlun the plat boundary. The ariginal preliminary plat shows a pazfial cul-de-sac at the plat boundary for these rvads. Ariother item that needs Ca he clarified is the 8ffi Avenue taper fram the west edge of this plat to the - intersectxon of Bawdish and e Avenue that is requiced as part af the roadway widening The entjre taper must }ae construc#ed within the right-of-way If you find evidence that the right-of-way rs less than expected, please subraut the inforination sa that we can confu-m thrvugh our own research.
