JAN 111995 BEFORE THE BOARD OF COUNTY COMMISSIO~JANE COUNTY OF SPOKANE COUNTY, WASHINGTON NG DEPARTMENT IN = MATTER OF ZE-31-94, ZONE ) FINDINGS, OF RECLASSIFICATION FROM UR.BAN RESIDENTIAL-3.5 FACT, (UR-3.5) TO URBAN RESIDENTIAL-22 (UR-22) ) DECYSION AND - ) CONDITIONS SPONSOR: DON HENRICHS e THIS MATTER, being the consideration by the Board of County Commissioners of Spokane County, hereinafter referred to as the "Board", of an appeal of the Spokane County Hearing Examiner Committee decision of August 22, 1994 approving Zone Reclassification File No. ZE-31-94, for the purpose of developing a fifty-two (52) unit multi-family complex on approximately 2.4 acres of land, hereinafter referred to as the "Proposal"; and the Board of County Commissioners having held a de novo public hearing on October 11, 1994, and having fully considered all testimony presented, the documents submitted and the public record files; and the Board further having individually visited or being familiar with the site and vicinity in question and having rendered an oral decision on tlle 8th day of November approving said proposal with mod.ifications, hereby enters the following: FINDINGS OF FACT 1. The proposal is generally located east of and adjacent to McDonald Road, approximately 700 feet south of Mission Avenue, in the NE 1/4 of Section 15, Township 25 North, Range 44 E.W.M., Spokane County, Washington.. 2. The original proposal consists of a zone reclassification request from Urban Residential-3.5 (UR-3.5) to Urban Residential-22 (UR-22) for a 52 unit multi- family complex on approximately 2.4 acres. 3. At the public hearing held by the Board, the applicant agreed to modify the proposal in conformance with conditions of approval recommended by the Planning Department, including changes to the proposed building height, setbacks, landscaping and density. This mod.ificarion reduceti the total number of units in the proposal to 44 units; fo: an approximate density of 18.33. 4. The Hearing Examiner Committee (HEC) held a public hearing on August 18, 1994, subsequent to which by the Findings of Fact, Conclusion and Decision dated August 22, 1994, it approved the proposal. 5. The owners of adjacent property timely filed an appeal of the Hearing Examiner Committee decision with the Board on August 26, 1994. 6. The legal requirements for public notice for the public hearing held by the Board have been fulfilled. , 7. The Board takes notice of the provisions of the Spokane County Generalized Comprehensive Land Use Plan, the Spokane County Zoning Code, the Spokane ~ County Code, the expired Spokane Counry Zoning Qrdinance, and the Program to ~ Implement the Spokane County Zoning Code. ~ 8. The Board adopts the Planning Department's and the Board of County Commissioners files in ZE-30A-89 and ZE-31-94 as part of the record. 9. The oral testimony presented at the public hearing before the Hearing Examiner Comrnittee did not comprise part of the record before the Board and was not considered by the Board in its decision. 10. At the public hearing held by the board, owners of adjacent property objected to the proposal based on the impacts to roadways, schools and neighborhood , , .'y ♦ 1 r1: • V BOCC FINDINGS ZE-31-94 Page 2 compatibility. The appellants also contended that conditions had not substantially changed to support the requested rezone, that there was insufficient sewer capaciry to serve the proposal, and that the applicant should be required to reimburse appellants for a portion of their costs incurred in financing the installation of public sewer facilities in McDonald Road. 11. The Comprehensive Plan designates the area encompassed by the proposal as , Urban. ~ 12. The original zoning of the property described in the application was Agricultural Suburban (AS) adopted in 1955 under the now expired Spokane County Zoning Ord.inance. The site was redesignated by Spokane County on January 1, 1991 to Urban Residential-3.5 (L1R-3.5) under the Spokane County Zoning Code, pursuant to the Program to Implement the Spokane County Zoning Code. , 13. In 1990, the site was given preliminary plat approval for six (6) lots, and Planned Unic Development (PUD) Overlay, under Pla.nning Department Fi1e No. PE-1581-89/ PUDE-4-89, and a zone reclassification from Agricultural Suburban (AS) to Urban Residential-22 (LJR-22) pursuant to Planning Department File No. ZE-5489 granted subject to final plat approval. The preliminary plat, if finalized, would create six (6) lots and common open space for development of inedical offices. This condirional zoning was not nullified by the 1991 redesignation of the site to Urban Residential-3.5 (UR-3.5). 14. In 1989, a five acre site located d.irectly north of the proposal, at the southeast corner of McDonald Road and Mission Avenue, was rezoned (ZE-30-89) under the Spokane County Zoning Code to Urban Residential-22 (UR-22), for the purpose of developing medical offices. Following the 1989 rezone, the five acre site was short platted into a southerly portion of 1.23 acres and a northerly portion on which medical offices were later constructed. 15. A request to change conditions (ZE-30A-89) for the southerly 1.23 acres of the property rezoned in ZE-30-89 to allow the installarion of 26 multi-family units at a density of 21 units per acre, in place of the medical offices proposal, was heard and approved by the Board at the same time as the current proposal. 16. A 10.7 acre parcel of land (owned by the appellants) located directly east of the proposal was rezoned to the Urban Residential-22 (UR-22) and Urban Residential-12 (UR-12) zones in 1990 for development of 214 multi-family units at a density of 21.6 units per acre. Further east, a rezone to the Urban Residential-12 (UR-12) and Urban Residential-22 (UR-22) zones was approved in 1992 for development of 154 multi- family units, at a density of 19.35 units per acre, and for medical offices. 17. Single family residences are located west of the site across McDonald Road and south of the site. Single family residences, multi-family dwellings, a retirement center and professional offices characterize the area surrounding the proposal, with Valley General Hospital located approximately 1/4 mile west of the site. 18. The proposal is located adjacent to McDonald Road, a designated arterial. Public sewer was installed in McDonald Road between 1991-1992, and the roadway was recently widened and improved to four lanes with curb and sidewallc through a County road project. - 19. The Spokane County Arterial Road Plan designates McDonald Road as a Minor Arterial with a recommended right of way width of 80 feet. In order to unplement the Arterial Road Plan, a strip of property 8 and 1/2 feet in width along McDonald Road should be set aside as future acquisition area (FAA) as recommended by the County Engineer. The proposal has been conditioned to set aside adequate right of way for future acquisition by the County. 20. The transportation element of the Comprehensive Plan recommends a 35 foot setback from designated arcerials. The proposal should be conditioned to provide a 35 foot structure setback from McDonald Road, in order to minimize the proposal's impact on the single family area located to the west across McDonald Road. 21. The proposal will generate less traffic than would use of the site for medical offices, as approved in the 1990 rezone and preliminary plat of the site, including projected traffic impacts to the intersection of Pines Road and Mission and to the Pines Road and I-90 Interchange. - -_...~..Y...._._ _ . . - • , .o- ~ . ~r . BOCC FINDINGS ZE-31-94 Page 3 22. Inclusion of the condition of approval requested by the Washington State Department of Transportation (WSDOT) in its letter to the Hearing Exa.miner Committee of August 17, 1994, limiting traffic from the proposal to that which would have been generated under the medical offices proposed for the site, is necessary to mitigate the impact of the proposal on the area's transportation system. 23. As indicated by the Centra.l Valley School I?istrict, there is inadequate student housing to serve the area of the proposal. The proposal will increase such deficiency when developed and the proposal should be conditioned to require the applicant to enter into a voluntary agreement with the school district to mitigate the impact of the proposal on the school district. The applicant's agent tesafied at the public hearing before the Board that the applicant agreed to enter into such voluntary agreement. 24. There is a deficiency of public park land in the East Valley area and the proposal T will increase the need for park facilides when developed. Approval of the change of conditions should be conditioned to require the applicant to negotiate and enter into a voluntary agreement with the Spokane County Department of Parks, Recreation and Fair to dedicate land or pay impact fees in lieu of dedication, prior to the issuance of building permits, in order to mitigate such impacts. The applicant's agent testified at the public hearing before the Board that the applicant would agree to enter into such voluntary agreement. 25. Permanent design capacity in the McDonald Road public sewer line was previously allocated by County Utilities for the equivalent of 45 of the 70 multi-family units being approved by the Board in ZE-30A-89 and ZE-31-94. 26. It is reasonable for the County, through negotiated connection agreemencs, to allow permanent connection of no more than 45 units in ZE-30A-89/"LE-31-94 to the McDonald Road public sewer facilities, and to allow temporary connecdon of the remaining units approved in ZE-30A-89I'ZE-31-94 to such facilities until the installation of public sewer facilities west of McDonald Road. 27. The County's 1991 developer connecdon agreement with Cedar Chateau Estates granted such owner the right to reimbursement for $105,000 of its costs incurred for the McDonald Road sewer facilities, solely from any bond proceeds issued within ten years from the date of such agreement, pursuant to formation of a Utility Local Improvement District (ULID) utilizing such facilities and subject to ' assessment of Cedar Chateau Estate's property in such ULID. 28. Under the 1991 developer connecdon agreement with Cedar Chateau Estates and the County's 1992 developer connecaon agreement with Cedar Chateau Estates B, the County has exclusive authority to deten-nine who and under what circumstances other owners of property can connect to the County's public sewerage system through the McDonald Road Facilities. 29. The County is not obligated to require the owners of property in ZE-30A-89i ZE-31-94 to reimburse Cedar Chateau Estates or Cedar Chateau Estates "B" for Cedar Chateau's costs to finance the McDonald Road sewer facilities. Such owners will be required to pay an equitable share of the costs of the County's public sewer system through connecdon agreements with the County. 30. The proposal is generally consistent with the Goals, Objectives and Decision Guidelines of the Comprehensive Plan (references in the findings herein and below to the "proposal' mean the proposal as modified by the applicant and as condirioned by the Board). 31. The proposal is consistent with the intent of the Urban category, which is intended primarily for residential development, including multi-family. The Urban category contemplates a mixture of single family, two family and multi-family along with neighborhood commercial and light industrial uses. 32. The proposal is consistent with the recommendations of the Urban category for multi-family development, with direct access to McDonald Road and near access to Mission Avenue, both arterial streets, as well as access to public transportation service. 33. The proposal, along with the proposal in ZE-30A-89, provides transition between the medical offices to the north and the single family area to the south. The height limitation for buildings, the 35 foot setback required along McDonald Road and the . , B OCC FTNDINC S ZE-31-94 Page 4 FAA setback provide transition between the single family area located west of McDonald Road and the taller 2-3 story buildings located east of the proposal. 34. The structure height limitation, 60 foot setback and the 20 foot Type I landscaping buffer required for the proposal along its south property boundary, as well as the reduced density of the proposal in the south 200 feet of the site renders the proposal consistent with the single family area located to the south. 35. The proposal will maintain the consistency of adjacent single family a.rnenities, and will not negarively impact the architectiral character of the neighborhoai. The ' proposal is compatible with surrounding land uses. 36. Circumstances have substantially changed in the area since the original zoning of the property was approved in 1955 to warrant approval of the proposal. Further, substantial changes have occurred in the area even since the conditional rezoning and preliminary plat of the property in 1990 and the crossover zoning of the property in 1991 to Urban Residential-3.5 (UR-3.5) to warrant approval of the proposal, including the installation of public sewer in McDonald Road, road improvements to McDonald Road, the increased and continuing demand for residential housing, and land use and zoning trends in the area. 37. The proposal will not have a significant probable adverse impact upon, and bears a substantial relation to, the public health, safety, and general welfare. 38. The provisions of RCW 43.21 C(The State Environmental Policy Act) have been complied with and a Deternunation of Nonsignificance was issued. The Board concurs with the Detennination of Nonsignificance. 39. The proposal is consistent with the requirements of the Zoning Code and other applicable land use controls. ~ DECISION The Board does hereby approve the zone reclassification request from Urban Residential-3.5 (UR-3.5) to Urban Residenrial-22 (UR-22), (as modified by cond.itions of approval) subject to the following additional conditians.

' .J BOCC FINDINGS ~ ZE-31-94 ~ Page 8 SPOKANE COUNTY AIR POLLUTION CONTROL AUTHORITY • 1. All air pollution regulations must be met. 2. Air pollution regulations require that dust emissions during demolition, construction and excavation projects be controlled. This may require use of water sprays, tarps, sprinklers or suspension of activity during certain weather conditions. Haul roads should be treated, and emissions from the transfer of earthen material must be controlled, as well as emissions from all other construction-related acovities. 3. SCA.PCA strongly recommends that all traveled surfaces (i.e., ingress, egress, parking areas, access roads) be paved and kept clean to minimize dust emissions. 4. Measures must be taken to avoid the deposition of dirt and mud from unpaved surfaces onto paved surfaces. If tracking or spills occur on paved surfaces, , measures must be taken immediately to clean these surfaces. 5. Debris generated as a result of this project must be disposed of by means other than burning (i.e., construction waste, etc.). 6. All solid fuel burning devices (wood stoves, pellet stoves, etc...) must comply with local, state, and federal rules and regulations. WASHINGTON STATE DEPARTMENT OF TRANSPORTATION 1. Due to the operational problems currently being experienced on Pines Road, this proposed project shall not generate tiraffic in excess of the original proposed project for medical offices (in PE-1581-89/PUDE-489/ZE-54-89), based on the most current trip generarion rates. , B Y TBE ORDER OF THE B OARD THIS 10'TH DAY OF JANUARY, 1995.

To the north is Short Plat 778-92, to the east . is Cedar Chateau Estares, an apartment complex, and to the south is Gulhric's Valley View 2nd Addition. The site is generally flat with no trees ar sigliticant vegetatiun at present. Ttie proposed project encompasses construction of tfuee apartnlent buildings, for a total of 44 dwelling units. rChe buildings and garages are to rLavz composition roofing. For retention and disposal of storrnwater collected on the site, "208" grassy ponding areas will be consiructed at the northwest corner, the west frontage, and along the east baundary of the site. Ttvee drainage basins are identified on the site, referred to as the "North 13asin," the "West Basin," and the "East Basul." Surface runoff from the asplialt will reach the ponds via curb inlets. 4utilow will be through a Type "A" drywell located within each pond. The soils ai the siie are Crarrison series gravelly loarn, whicli are recognized by Spokane County as having very rapid permeability and an infiltrarion rate of 0.3 c.f s. for Type "A" drywells. rl'he dra.inage design and outilow calculations are based on the assumption that the natural materia.l at the locations of the drainage facilities wili provide outilow at the rate of 0.3 c.t:s. through the drywell and 0.36"/hr. lhrough pond Door. ~ As per Spokane County requirements for "208" treatment, all on-site asphalt pavement sui-faces and composition roofing are uicluded in the "208" poncling calculations. 1n addition, the gravel area at the northeast corner of the site is included in ttie "208" calcu.lafiions, since it is designated for recreational vehicle parking. The ponding depth for treatment is G". The ponding depih for storage in excess of outflow is 8". Sufficient storage volume for a 10-year storm event, as per the bowstruig calculations, is provided within the first 8" of ponding in each pond.

Refer to the l" = 20' Drainabe Plan for the site layout and basin divides. For the proposed drainage ponds wit1t 3:1 side slopes, the pond volume cau be calculated with two components: ttie volume directly above tlle pond floor plus the volume above the side slopes. 'Co coinpute the volume at a.uy ponding deptJi, oiily two parameters need to be kriowti: pond floor area aiid pond floor perimeter length (both are specified on tlie Drainage Plan map). Volume is calculated at 6" depth for "208" treatment aiid at 8" depth for storabe, as follows: At 6" depth: Pond Volume =(0.5 ft. deptll x pond floor area) +(1 /2 x 0.5 x 1.5 x pond floor perimeter) =0.5 A+0.375P At g" depth: Pond Volume =(0.67 ft. depth x pond floor area) +(112 a 0.67 x 2.0 x pond floor perinieter) = 0.67A + 0.67P 2.0 feet 1.5 feet ~ , - ~ ~ - ~ ~ . . ~ - 0.67 6" = 0.5 ft.

To the not-th is Short Plat 778-92, to the east is Cedar Chateau Estates, an apartment complex, a.nd to the south is Guthrie's Valley View 2nd Addition. rl'he site is generally flat with no trees or sigiuiicant vegetation at present. T}le proposed project encompasses construction of ttv-ee apartmeni buildings, for a iotal of 44 dwellin; units. The buildings anci garages are to have composition roofng. - For retention and disposal of stormwafier collectcci on the site, "208" grassy ponding areas wili be construcied at the northwesl corner, the west frontage, and along the east boundary of the site. Three drainabe basins are icientified on the site, reFerred to as the "N'orth Basin," the "West Basin," and the "East Basin." Surface runoff froin the asphalt will reach the ponds via curb inlels. Outllow will be through a Type "A" cilywell located wittun each pond. The soils at the site are Garrison series gravelly loam, which are recognized by Spokane County as having very rapid permeability and an infiltration rate of 0.3 c.f.s. for Type "A" drywells. rrhe dra.inage design and outflow calculaiions are based on tlie assumption that the natural material at the locations of the drainage facilities will -provide oultlow at the rate of 0.3 c.f.s. tlu-ough the drywell a.nd 03 )6"/hr. tfu-ough pond floor. As per Spokane County requiremenis for "208" treatment, all an-site asphzlt pavement surfaces and composition rooting are includeci in the "208" ponding . calculations. ln addition, the gravel area at the noriheast corner ot the site is included in the "208 " calculations, since it is designaleci i'or recrcational vetvcle parking. The ponding depth for treatment is 6". The ponding depth for storage in excess af outtlow is S". Suflicient storage volume for a 10-year storm event, as per the bowstruig calculations, is -provided within the first 8" of ponding in each pond.

Refer to the l" = 20' Draina3e Plan for the site layout and basin divides. For the proposed drainage ponds wit1i 3:1 side slopes, the pond volucnc cau be caiculated with two components: the volunle directly above the pond floor plus die volume above tiie sidc slopes. To coinpute tlie volwne at any ponding depdi, only two parameters need to be l:nown: pond floor area and pond floor perimeter length (both are specified on the Drainage Plan map). Volume is calculated at 6" deptli for "208" treatjnent and at 8" depth for storage, 7s follows: At 6" depth: Pond Volume =(0.5 ft. depth x pond floor area) -4- (1/2 x 0.5 x 1.5 x pond floor perimeter) =O.SA+0.375P At 8" depth: Pond Volume =(0.67 ft. depth x porid floor area) +(1/2 x 0.67 x 2.0 x pond floor perimeter) = 0.67A + 0.67P 2.0 feet d ~---1.5 feet 3 -----------F---------- 8~~ _ 0.o7 n 6" = 0.5 ft. 1( ' Fonci r loor ~*~****~:x*~***x***~*x~**z*****~*~.~*~x**~~~*c:r:x***~*~***~*~ NOTE: A11 impervious surfaces are included in hydrolory and bowstring calculations, except concrete walks.

To the north is Shoi-t Plat 778-92, to the east is Ceda.r Chateau Estales, an apartment complex, and to the south is Guthrie's Valley View 2nd Addition. The site is generally llal with no trees or signiiicant vegetation at present. The proposed project encompasses const.ruction of three apartment buildings, for a total af 44 dwelling units. 7'he buildings and garages are to have composition roofing. For retentian and disposal of storrnwater collected on the site, "208" grassy ponding areas will be constructed at the northwest corner, the west frontage, anci along the east boundary of the site. Three drainage basins are identified on the site, referred to as the "North Basin," the "West Basin," and the "East 13asin." Surfiace runoff from the aspllalt vvill reach the ponds via curb inlets. Outflow will be tllrough a Type "A" drywell located withln each ponci. The soils at the site are Garrison series gravelly loam, wtvch are recognized by Spokane County as having very rapid permeability and an inFiltration rate of 0.3 c.f s. for `I'ype "A" drywells. 'Che drainage design and outflow calculatians are based on the assumption that the natural material at the locations of the drainage facilities will provide outFlow at the rate of 0.3 c.f.s. through the drywell a.nd 0.36"71ir. throubh pond floor. As per Spokane County renuirements for "208" treatmeni, all on-site asphalt pavement surfaces and composition rooling are uicluded in the "208" ponding calculations. In addition, the gravel area at the northeast corner of the sile is included in the "208" calculations, since it is designated for recreational velvcle parking. The ponding depth for treatment is 6". The ponding depth tor storage in excess of outflow is S". Suflicient storage volume for a 10-year storni evenl, as per the bowstring calculations, is . provided within the first 8" of ponding in e3ch pond. . . llcs:;n A!li:incc: M'ac 44 Ap:s. - Siornllval-s Dr:~in::Z;~ Re; or. ? dra i nabe2lca ! cs\ 13 2,15 "208" PO.ND VOLUNIE CALCLILAT7QNS The following pages contain data for the on-site drauiage basiiis and "208" storiiiwater reCention ponds. (Zefer to the 1" = 20' Drainage Plan for the site layout and basin divides. For the proposed draiuage poncls witli 3:1 side slopes, the porid volumc can be caiculated with two coffiponents: the volume directly above the pond floor plus the volume above the side slopes_ To compute the volume at any ponding dept}i, orily ttivo parauneters need to be known: pond floor area and pond floor perimeter length (both are speci.fied on the Urainage 1'lan map). Volume is calculated at 6" depth for "208" treatment and at 8" depth for storage, as follows: At 6" depth: Pond Volume =(0.5 ft_ depth x pond floor area) (1/2 x 0.5 x 1.5 x pond floor perinieter) =0.5 A+0.375 P At 8" depth: Pond Volume =(O.b7 ft. depth x pond floor area) + (1/2 x 0.67 x 2.0 x poiid floor pcrin-jctcr) = 0.67A + 0.67P 2.0 feet : / i - feet 3~ ~ = G.o7 6" = 0.5 ft. ~ - ' Pond FIoor N0TE: All impe"ious surfaces are included in hydrology and bowstring calculations, except concrete walks.

Concrete waUcs are non-polluting, and off=site drainage should not reach the "208" ponding areas.

To the norih is Sliort ]'lat 778-92, to the east is Cedar Ctialeau Estates, an apartment complex, and to t11e south is Guthrie's Valley View 211d Addition. The site is gener~illy ilat witl~ no trees or significant vegetatrun at present. The proposed project enconlpasses construction of three aparlmenl buildings, for a total , of 44 dwelling units. rl'he bu.ildings and garages are to have composition roofing. For retention and disposal of slormwater collected on the site, "208" grassy ponding areas wiU be constructed ar the northwest corner, the west i=rontage, anci along the east boundary of the site. 7'luee drainage basins are identiiied on the site, referred to as the "North Basi.n," the "West l3asin," and the "Easfi Basin." Surtace rulioff from the asphalt will reach the ponds via curb inlets. Outtlow will bc tliroubh aType "A" drywell located wittvn each pond. The soils at the site are Garr-ison series gravelly loam, which are recognized by Spokane County as having very rapid pernieability and 1n infltration rate of 0.3 c.f.s. for Type "A" drywells. The dra.inage design and outflow calculations a.rc based on the assumption that the natural material at the locations of the drainage tacilities wil( provide outtlow at the rate of 0.3 c.f.s. through the drywell and 0.36"/hr_ through pond floar. As per Spokane County requirements for "20$" treatnient, all on-site asphalt pavement surfaces anci composition roofing are included in the "208" ponding calculations. .ln addition, the gravel area at the nol-theast corncr of the site is included in the "208" calculations, since it is designaled lor recreational vehicte parking. The ponding depth for treatment is 6". The ponding depth for storage in excess ot autilow is 8". Sufficient storage volume for a 14-year stornl event, as per the bowstring calculaiions, is provided Urithin the fii-st S" o.f ponding in each pond.

Refer to the 1" = 20' Drainage Plan for tl►e site layout and basin divides. For the proposed drainase ponds with 3:1 side slopes, the poitd volume can be calculated with two components: the volume di.rectly above the pond floor plus the volume above tile side slopes_ To cornpute the volume at a.ay ponciing depth, only two parameters need to be knowii: pond floor area and pond floor perimet.er length (both are specified on die Drainage Plari map). Volume is calculated at 6" depth for "208" treatment and at 8" depth for storagc, as follows: At 6" depth: Pond Volume =(O.S ft. deptli x pond floor area) +(1i2 x 0.5 x 1.5 a poad floor perimeter) =0.5A+0.37SP At 8" depth: !'ond Voltime =(0.67 ft. depth x pond floor area) +(l/2 x 0.67 x 2.0 x pond floor perimeter) = 0.67A + 0.67P 2.0 feet ]_5 feet - - ~ ~ _ G. o7 iL 6"=O.Sft.

PRQJ EC`1~ DLSCRIP7'lON The project site is localed on the east side of McDonalcl Road about 700' south ot' IVlission Avcnue in the Spokaiie VaJley. To the north is Shorl Plat 778-92, to the east is Cedar Chateau Estates, an apartment complex, and to the south is Guthrie's Va11ey . View 2nd Addition. The site is genera.lly flat with no trees or signiiicant vegetation at present. , . . The proposed project encompasses constniction of threc apalrtnient builciings, far a totai of 44 dwelling units. The buildings and garages dre to have compositian roof ng. For retention and disposal of stormwater collected on the site, "208" ~,nassy ponding areas will be constructed at the northwest corner, the west frontage, and a.long the east bounda.ry af'the site. Tliree drainage basins are identified on tlie site, referred to as the "NorCh 13asin," the "Wesl Basin," and the "East 13asin." Surface runoiffrom the asphalt will reach the ponds via curb inlets. Outflow will be through a Type "A" drywell located within each pond. rl'he soils at the site are Garrison series gravelly loam, which are recoc gmized by Spokane County as having very rapid permeability and an in-filYration rate of 0.3 c.f.s. for 'Type "A" dryweUs. T}le dra.inage design and outflow calculations are based on the assumption that the natural material at the locations of the dra.inage facilities will provide outflow at the raie of'0.3 c.f.s. lhroueh the drywell and 0.36"/hr. throubh pond floor. As per Spokane County requirements for "208" ireatment, all on-sile a.sphalt pavement surfaces wid composition roofing are included in the "208" ponding calculations. In addition, the gravel area at the nartheast corner of the site is inciuded in the "208" calculations, since it is designated for recreationa.l vetucle parking. The ponding . deptll for treatment i5 f". The ponding depth for storage in excess of outflow is 8". Sufficient storage volume far a 10-year stornl event, as per the bowstring calculations, is provided within the fi_rst 8" of ponding in each pond.

Refer to the 1" = 20' Draiuage Plan for tfie sife layout and basin divides. For the proposed drainage ponds witli 3:1 side slopes, the pond volume can be calculated with two components: the voluine directly above tlle pond floor plus t1ie volume above the side slopes. To , compute the volu,ne at any ponding deptli, only two parameters neecl to be l:iiown= pond Iloor area and pond floor perimeter tength (botli are specified on thc Draina3e Plan map). Volume is calculated at 6" depth for "208" treatment and at 8" deptii for storage, as follows: At 6" depth: 'Pond 1'olume =(0.5 ft. depdi x pond floor area) +(1/2 x 0.5 x 1.5 x pond floor perinieter) =0.5A +0.375P At 8" depth: Pond Volume =(0.67 ft. depth x pond floor area) -r (1/2 x 0.67 x 2.0 x pond floor perimeter) = 0.67A + 0.67A 2.0 feet „ . 1.5 feet : • ~ 1- - - 8 ~'1.07 11 6" = 0.5 ft. Poiid r loor NOTE: All irnpervious surfaces are included in hydrology anci bowstrincl-, calculations, except concrete walks. Thus, only asphall paveinerrl, campositioir rvof rlg alicl the gr«vel R.V ptrrking ut-ea are considered fOr "208" lreatnienl in the f rst b" ponding depth. Concrete wall:s are non-polluting, and off-site drainage shuuld not reach the "208" ponding areas.
