The Hearing Examiner may consider additional environmental related tesrimony at the public hearing. I V. PLANNYNG DEPARTMENT SUMMARY AND RECOMMENDATION The Urban category of the Comprehensive Plan supports multifamily residential developments when located near heavily traveled streets. Multifamily residential uses are consistent and compatible with existing and proposed multifamily units located west and southwest of the site. Landscaping requirements for the Urban Residenrial-22 (UR-22) zone will assist in buffering surrounding single family homes from multifamily development on the site. The Planning Department has recommended modificarions to the site glan for height limitations, additional landscaping, buffering,and setbacks. Additional conditions are attached which have been recommended by other county agencies and departments. Based on the above and ocher departmental reviews, the Planning Department recommends approval of the zone change to Urban Residential-22 (UR-22) for the , development of 187 apartment units and a sewer density bonus of 4.5 units per acre as conditioned. V . CONDITI4NS OF APPROVAL i. All conditions imposed by the Hearing Examiner Committee shall be binding on the "Applicant", which terms shall include the owner or owners of the property, heirs, assigns and successors. i i.

Parcel Nos. 45242.0636, 45242.0637, & 45242.0642 Dear Carol, Under the requirements of Zone Change ZE 42-92, you have been required to dedicate a strip of land on the north sides of the above-referenced parcels. The strip is irregularly shaped, approximately 660' long east-west, and tapering from 18.75' to 6.25' wide north-south. During the zone change process the wide end of the strip was located on the easternmost property line and the narrow end on the westernmost property line. During the course of further review by the Spokane County Engineers Departrnent, it has become evident that the more suitable layout for the dedication would be to locate the 18.75' end on the west property line and the 6.25' end on the east property line. Therefore, the County is requesting that this revised layout be the land that is dedicated. The square footage of land to be dedicated would remain the same, and the location of the buildings as proposed would not be affected in any way. Please let us know if you are agreeable to this arrangement as soon as possible, so as not to delay the building permit. Please feel free to call if you have any ftzrther questions or concerns regarding this matter. Sincerely, William A. Johns, P.E. County Engineer 1026 W.

Whipple, P.E. , Aspen Village Apartments _ Drainage Narrative GENERAL ' The Aspen Village Apartments are a development of a 165-unit apartment complex and 68 garages on a 7.3 acre site along 4th Avenue in the Spokane Valley, adjacent and south of the - old Milwaukee Road Right of Way, within Spokane County, Washington. The site is currently - vacant with weeds and dirt stackpiles. The current zoning is UR-22 which is consistent with the ; development proposed. A 1" to 400' scale vicinity and soils map is provided. PURPOSE The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of stormwater runoff created by the development of the Aspen Village Apartments project. The storm drainage facilities on this project will be designed to dispose of runoff from the ten year design storm. This development is within the Aquifer Sensitive Area of Spokane County and is subject to '208' requirements. For this project the 10-year curve from : the Spokane, Medical Lake, Reardon, Cheney and Rockford intensity, duration and frequency (IDF) curves were used. ANALYSIS METHODOLOGY The Rational Method, which is recommended for basins less than ten acres in size, will be used to determine the peak discharges and runoff volumes for all onsite basins. PROJECT DESCRIPTION The Aspen Village Apartments project will develop 165 apartment units and 68 garages on an approx. 7.3 acre parcel. The Aspen Village Apartments project is located in the NW 1/4 of Section 24, T. 25 N., R. 44 E., W.M. in Spokane County, Washington. TOPOGRAPHY At the present time the Aspen Village Apartments site is a fairly flat vacant.lot with weeds, old building materials and dirt stockpiles. For development purposes, the natural sloping was used for design and is maintained as possible throughout the project. Inland Pacific Engineering Company D 1 Aspen Village Drainage Report SOILS As can be seen from the accompanying soils map from the Spokane County Soils Survey as performed by the SCS, the site consists of the Garrison Series of soils, primarily Garrison Gravelly Loam (GgA) on 0 to 5-percent slopes. These soils as defined, are excessively drained and have moderately rapid permeability. Within this area, due to soil types and slopes, this tyge of soil can be expected to drain slowly with a minimum potential for erosion. As defined within the Spokane County Drainage Guideline, this type of soil has been pre-approved for the installation of drywells. DRAINAGE NARRATIVE Offsite Based upon the topography of this site there are no offsite basins considered for this project. ' Onsite All onsite drainage will be collected and treated using the "208" runoff inethod as described in the Spokane County Guidelines for Stormwater Management. To facilitate this analysis the Aspen Village project was divided into 5 permanent basins A through E. These basins are shown on the attached Basin Map "208" Calculations Within each basin the parking lots and/or streets are either left as an entire unit or divided into sub-basins by curb drops or inlets which capture upstream stormwater runoff from the impervious street surface and direct the runoff into grassy '208' ponds either by overland or piped flows. As shown on the '208' calculation worksheet included, the '208' storage volume provided is adequate to perform '208' treatment for the runoff created by the first half inch of rainfall. Curb Drop Calculations It is usually necessary to check the adequacy of the curb drops provided to divert the runoff from the gutter into the '208' ponds. Please note that no curb drop calculations are provided for this project as the curb drops are in the sump condition where the assumption is that the 4.0' curb drop can handle 4.0 cfs. ; Inland Paciftc Engineering Company D2 Aspen Village Drainage Report DRAINAGE CALCULATI0IVS SUMMARY Calculations have been included for Drainage Basin considerations such as QTR 55 and pond routing calculations, Peak Flow, Time of Concentration, "208" sizing, drywell requirements, inlet sizing, curb drops as well as culverts and pipe flow some of which are summarized below with the remaining calculations in the appendix. , Within the calculation section several sketches, as well as pond detai.ls from the plans have been , incorporated to demonstrate assumptions and conclusions. . Basin A- Basin A is the largest Basin within the Project, it runs north from 4th Avenue to the Spokane County ROW approximately 640 feet north and south. Within this basin there are four buildings, parking, garages and a drive aisle. Basin B- Basin B is the second largest basin by area however, it has the second lowest runoff coefficient at 0.4996. This is due to the fact that there are two building, parking area and open space within this ba.sin. , Basin C- Basin C is located within the southwest corner of the site contai.ns one building, some parking, a drive aisle and ogen space. Basin D- Basin D is the central western basin laying between Basin C and Basin E. This basin contains two buildings parking area, a few garages, drive ai.sle and an open space to the rear between the buildings. Basin E- Basin E is located within the northwest corner of the site containing one building, surface pazking, garages and part of the open space at the rear of the building adjacent to the Spokane Co. ROW. Basin F- Basin F contains that portion of 4th Avenue directly in front of the project. Due to the size of the frontage and the proposal there is no room to provide 208 for this portion of the road. Therefore, a type B drywell is included for direct discharge.

' HEC Order for ZE-42-92 Page 5 Prior To Issuance Of ABuildine Permit C?r Use C1f The Propertv As -Proposed: 3. Access permits for approaches to the county road system shall be obtained from the Spokane County Engineer. 4. The applicant shall submit for approval by the Spokane County Engineer road, drainage and access plans. 5. The applicant shall submit for approval by the Spokane County Engineer and the Spokane County Health Distirict a detailed combined on-site sewage system plan and surface water disposal plan for the entire project, or portion thereof, if the development is to be phased. 6. A parlang plan and traffic circulation plan shall be submitted and approved by the Spokane County Engineer. The design, location and arrangement of parkina stalls shall be in accordance with standard traffic en-aineerina practices. Paving or surfacing as approved by the County Engineer, will be required for any portion of the project wrich is to be occupied or traveled by vehicles. 7. T'he consti-uction of the road improvements staced herein shall be accomplished as approved by the Spokane County Engineer. 8. The County Engineer has designated Typical Roadway Secrion Number One, Local Access standard for the improvement of Fourrh Avenue, which is adjacent to the proposed development. This will require the addition of approximately 10-12 feet of asphalt along the frontage of the development. The consa-uction of curbing and sidewalk is also requixed. 9. A11 required improvements shall conform to the current State of Washington Standard Specifications for Road and Bndge Construction and other applicable County standards and/or adopted xesolutions pertaining to Road Standards and Stormwater Management in effect at the date of construction, unless otherwise approved by the County Engineer. 10. Applicant shall conswct a paved and delineated approach(es) to meet the existing pavement on Fourth Avenue. 11. Roadway standards, typical roadway sections and drainage plan requirements are found in Spokane Board of County Commissioners Resolution No. 80-1592 as - amended and are applicable to this proposal. 12. No consmaction work shall be performed within the existing or proposed public right-of-way until a permit has been issued by the County Engineer.

The County Anerial Road Plan idenrifies Fourth Avenue as a Collector arterial. The existing right-of-way width of 40 feet is not consistent with that specified in the HEC Order for ZE-42-92 Page 6 Plan. In order to implement the Arterial Road Plan, in addirion to the required . right-of-way dedication, a strip of property 5 feet in width along the Fourth Avenue frontage shall be set aside in reserve. This property may be acquired by Spokane County at the time when arterial improvements are made to Fourth Avenue. 15. The County Arterial Road Plan idendfies the proposed South Valley Arterial as a Principal arterial. The existing right-of-way width of 75 feet is not consistent with that specified in the Plan. In order to implement the Arterial Road Plan, in addition to the required right-of-way dedication, a strip of property 22.5 feet in width along the Fourth Avenue frontage shall be set aside in reserve. This property may be acquired by Spokane Counry at the time when arterial improvements are made to South Valley Arterial. 16. There may exist utiliries, either underground or overhead, affecting the subject property, including property to be dedicated or set aside for future acquisition. Spokane County assumes no financial obligaaon for adjustments or relocation regarding these utilities. Applicant(s) should check wich the applicable utility purveyor and the Spokane County Engineer to determine whether applicant(s) or the utility is responsible for adjustment or relocation costs and to make arrangements for any necessary wozk. 17. The Spokane County Engineer, after review of this proposal, is concerned that an additional 1234 trips per day on Fourth Avenue could create a potential traffic circulation problem. Approximately 630 feet of 40 feet of asphalt and sidewalk has been const-ucted from Sullivan Road east on Fourth A.venue providing ample travel lanes and parlang for the existing multi-family structures. The County Engineer would recommend that beginning from the east property line of Person Addition and continuing approximately 520 feet to the proposed frontage of this development that the full pavement section of a typical Roadway Section # One, Local Access be designed and constructed by the applicant. Since Fourth Avenue is currently only 40 feet in width between the proposal and the East property line of Person Addition the paved secaon will utilize the fu1120 feet of right of way from centerline north, but would riot include sidewalk. Along the applicants frontage the full roadway secdon shall be constructed, including asphalt, curb and sidewalk per che Roadway Section # One, Local Access S tandard. 17. The County Engineer recommends that 2 accesses be provided to the site consideri►ia the number of units to be served and lack of access for emergency vehicles. 18. There shall be no vehicular access to the South Valley Arterial. SPOKA.NE COUNTY DZVZSION OF UTILITYES 1. Applicant shall mak-e connection to public sewer system. Sewer connection permit is required.

Todd R. Whipple, P. E. 11, 1 Aspen Village Apartments Drainage Narrative ~ GENERAL , The Aspen Village Apartments are a development of a 165-unit apartment complex and 68 , garages on a 7.3 acre site along 4th Avenue in the Spokane Valley, adjacent and south of the old Milwaukee Road Right of Way, within Spokane County, Washington. The site is currently vacant with weeds and dirt stockpiles. The current zoning is UR-22 which is consistent with the , development proposed. A 1" to 400' scale vicinity and soils map is provided. PURPOSE : The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of stormwater runoff created by the development of the Aspen Village Apartments project. The storm drainage facilities on this project will be designed to dispose of runoff from the ten year design storm. This development is within the Aquifer Sensitive Area , of Spokane County and is subject to '208' requirements. For this project the 10-year curve from the Spokane, Medical Lake, Reardon, Cheney and Rockford intensity, duration and frequency (IDF) curves were used. ANALYSIS METHODOLOGY , The Rational Method, which is recommended for basins less than ten acres in size, will be used to determine the peak discharges and runoff volumes for all onsite basins. PROJECT DESCRIPTION The Aspen Village Apartments project will develop 165 apartment units and 68 garages on an approx. 7.3 acre parcel. The Aspen Village Apartments project is located in the NW 1/4 of Section 24, T. 25 N. , R. 44 E. , W. M. in Spokane County, Washington. TOPOGRAPHY At the present time the Aspen Village Apartments site is a fairly flat vacant.lot with weeds, old building materials and dirt stockpiles. For development purposes, the natural sloping was used for design and is maintained as possible throughout the project. Inland Pacific Engineering Company D 1 Aspen Village Drainage Report ' SOILS , As can be seen from the accompanying soils map from the Spokane County Soils Survey as performed by the SCS, the site consists of the Garrison Series of soils, primarily Garrison Gravelly Loam (GgA) on 0 to 5-percent slopes. These soils as defined, are excessively drained and have moderately rapid permeability. Within this area, due to soil tyges and slopes, this type of soil can be expected to drain slowly with a minimum potential for erosion. As defined within the Spokane County Drainage Guideline, this type of soil has been pre-approved for the ; installation of drywells. DRAINAGE NARRATIVE Offsite , --Based upon the topography of this site there are no offsite basins considered for this project. Onsite ; All onsite drainage will be collected and treated using the "208" runoff inethod as described in the Spokane County Guidelines for Stormwater Management. To facilitate this analysis the Aspen Village project was divided into 5 permanent basins A through E. These basins are , shown on the attached Basin Map ' 11208" Calculaaions Within each basin the parking lots and/or streets are either left as an entire unit or divided into sub-basins by curb drops or inlets which capture upstream stormwater runoff from the impervious street surface and direct the runoff into grassy '208' ponds either by overland or piped flows. As shown on the '208' calculation worksheet included, the '208' storage volume provided is adequate to perform '208' treatment for the runoff created by the first half inch of rainfall. . Curb Drop Calculations ; _ It is usually necessary to check the adequacy of the curb drops provided to divert the runoff from the gutter into the '208' ponds. Please note that no curb drop calculations are provided for this project as the curb drops are in the sump condition where the assumption is that the 4.0' -curb drop can handle 4.0 cfs. Inland Paciftc Engineering Con3Pany D2 Aspen Village Drainage Report ' DRAINAGE CALCULATIONS SUMMARY - Calculations have been included for Drainage Basin considerations such as QTR 55 and pond ; routing calculations, Peak Flow, Time of Concentration, "208" sizing, drywell requirements, inlet sizing, curb drops as well as culverts and pipe flow some of which are summarized below with the remaining calculations in the appendix. Within the calculation section several sketches, as well as pond details from the plans have been , incorporated to demonstrate assumptions and conclusions. _ Basin A- Basin A is the largest Basin within the Project, it runs north from 4th Avenue to ; the Spokane County ROW approximately 640 feet north and south. Within this basin there are four buildings, parking, garages and a drive aisle. ; Basin B- Basin B is the second largest basin by area however, it has the second lowest runoff coefficient at 0.4996. This is due to the fact that there are two building, parking area and open space within this basin. ; Basin C- Basin C is located within the southwest corner of the site contains one building, some parking, a drive aisle and open space. - Basin D- Basin D is the central western basin laying between Basin C and Basin E. This basin contains two buildings parking area, a few garages, drive aisle and an open space to the rear between the buildings. Basin E- Basin E is located within the northwest corner of the site containing one building, surface parking, garages and part of the open space at the rear of the building adjacent to the Spokane Co. ROW. Basin F- Basin F contains that portion of 4th Avenue directly in front of the project. Due to the size of the frontage and the proposal there is no room to provide 208 for this portion of the road. Therefore, a type B drywell is included for direct ; discharge. , Inland Pacific Engineering Company D3 Aspen Village Drainage Repon ~ Table No. 1- Basin Summacy Table - Areas . - - - .
