Edward Hayes IWA Spokane County Air Pollution Control Authority Subject: SCAPCA COMMENTS REGARDING : File # 95002732 Following is a list of concerns/issues that, at a minimum, need to be addressed for this project. SCAPCA encourages proponents to contact their offices at 1 101 West College, Spokane, WA 99201 for additional information. ~ All air pollution regulations must be met. , ~ Air pollution regulations require that dust emissions during demolition, construction and excavation projects be controlled. This may require the 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 activities. SCAPCA strongly recommends that all travelled surfaces (i.e., ingress, egress, parking areas, access roads) be paved and kept clean to minimize dust emissions. ~ 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. Debris generated as a result of this project must be disposed of by means other than burning (i.e., construction waste, etc...1. ~ All solid fuel burning devices (wood stoves, pellet stoves, etc...) must comply with local, state, and federal rules and regulations. * Any changes to Spokane's transportation system may require a conformity analysis to determine that the project will conform with the Washington State Implementation Plan. Failure to meet SCAPCA regulations may result in delays, closure and civil and/or criminal sanctions. j Pnnfed on Rec;Kled Pacx r a REC'U-SPOKAidE CO. ' , ~lAY 2 71995 Dff OF BIOGS. 8Y: !

Whipple, P.E. , Farr Road Apartments Drainage Narrative GENERAL The Farr Road Apartments is a development of a 72-unit apartment complex and 39 garages on a 3.6 acre site along Farr Road 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 Farr Road 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' requi.rements. For this project the 10-year curves from the Spokane, Medical Lake, Reardon, Cheney and Rockford intensity curve 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 Farr Road Apartments project will develop 72 apartment units and 39 garages on an approx. 3.6 acre parcel. The Farr Road Apartments project is located in the NW 1/4 of Section 20, T. 25 N. , R. 44 E. , W. M. in Spokane County, Washington. TOPOGRAPHY At the present time the Farr Road 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. 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 Inland Pacific Engineering Company Dj Farr Road Apamnents Drainage Repart 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 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 Morningside project was divided into 2 permanent basins A and B. These basins are shown on the attached Basin Map 11208" Calculations Within each basin the 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 only curd drop is in the sump condition where the assumption is that the 4.0' curb drop can handle 4.0 cfs. 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 Inland Pacific Engineering Company D2 Farr Road Apartments Drainage Repart with the remaining calculations in the appendix. Within the calculation section several sketches, as well as details from the plans have been incorporated to demonstrate assumptions and conclusions. Basin A- Basin A is made up of the north part of the western most parking area in the project including half of the building as shown in the Basin Map. The water is intended to access Pond A-using overland and gutter flow through a curb drop. . Basin B- Basin B is made up of the remainder of the entire site. It is basically divided into two smaller sub basins each flowing from the high point in the center of the main drive/parking area. The water from the western sub-basin flows via overland and gutter flow to the emergency vehicle turn around, into a small "mini" pond or depression and then via a pipe to Pond B. The eastern sub-basin flows to a small "mini" pond or depression in the landscaping strip between the buildings, enters the "mini" pond via curb drops and then is conveyed to Pond B via a pipe.

Whipple, P. E. r Farr Road Apartments Drainage Narrative Please note that all revisions to this document based upon Spokane County comments are noted as italics. GENERAL The Farr Road Apartments is a development of a 72-unit apartment complex and 39 garages on a 3.6 acre site along Farr Road 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 Farr Road Apartments project. The storm drainage facilities on this project will be designed to dispose of rvnoff 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 Farr Road Apartments project will develop 72 apartment units and 39 garages on an approx. 3.6 acre parcel. The Farr Road Apartments project is located in the NW 1/4 of Section 20, T. 25 N. , R. 44 E. , W. M, in Spokane County, Washington. TOPOGRAPHY ' At the present time the Farr Road 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 Farr Road Aparnnents 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 type of soil can be exgected 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 Morningside project was divided into 2 permanent basins A, B and C. These basins are shown on the attached Basin Map 11208" Calculations Within each basin the 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 diarect 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 only curd drop is in the sump condition where the assumption is that the 4.0' 'curb drop can handle 4.0 cfs. Inland Paciftc Engineering Company D2 Farr Road Aparnnents Drainage Report r 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 made up of the north part of the western most parking area in the project including half of the building as shown in the Basin Map. The water is intended to access Pond A using overland and gutter flow through a curb drop. Basin B- Basin B is made up of the remainder of the entire site. It is basically divided into two smaller sub basins each flowing from the high point in the center of the main drive/parking area. The water from the western sub-basin flows via overland and gutter flow to the emergency vehicle turn around, into a small "mini" pond or depression and then via a pipe to Pond B. The eastern sub-basin flows to a small "mini" pond or depression in the landscaping strip between the buildings, enters the "mini" pond via curb drops and then is conveyed to Pond B via a pipe. Basin C- Basin C is made up of that portion of Farr Road fronting the project site. The approximate width of the Basin C frontage is approximately 217 feet. The basin includes 22.5 feet of pavement plus a 6 foot sidewalk. The grassy swale area is also include and contributes to the reduction in the C value from 0.90 to 0.7352. All of the runofffrom this basin will be handle in two small ponds and a single drywell Type A. The drywell will be connected to the southerly small pond via a Spokane County Inlet and pipe.

O ~oF ~ c~► ` l 2 54 62 ~ ~ EXPIRES 9/24/ Todd R. Whipple, P. E. 1 Farr Road Apartments Drainage Narrative GENERAL The Farr Road Apartments is a development of a 72-unit apartment complex and 39 garages on a 3.6 acre site along Farr Road 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 Farr Road 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 curves from the Spokane, Medical Lake, Reardon, Cheney and Rockford intensity curve 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 Farr Road Apartments project will develop 72 apartment units and 39 garages on an approx. 3.6 acre parcel. The Farr Road Apartments project is located in the NW 1/4 of Section 20, T. 25 N. , R. 44 E. , W. M. in Spokane County, Washington. TOPOGRAPHY At the present time the Farr Road 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. 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 Inland Pacific Engineering Company D 1 Farr Road Aparmients Drainage Repoi7 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 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 Morningside project was divided into 2 permanent basins A and B. These basins are shown on the attached Basin Map 11208" Calcula.dons Within each basin the 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 only curd drop is in the sump condition where the assumption is that the 4.0' curb drop can handle 4.0 cfs. 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 Jnland Pacific Engineering Company D2 Farr Road Apartments Drainage Report with the remaining calculations in the appendix. Within the calculation section several sketches, as well as details from the plans have been incorporated to demonstrate assumptions and conclusions. Basin A- Basin A is made up of the north part of the western most parking area in the project including half of the building as shown in the Basin Map. The water is intended to access Pond A using overland and gutter flow through a curb drop. Basin B- Basin B is made up of the remainder of the entire site. It is basically divided into two smaller sub basins each flowing from the high point in the center of the main drive/parking area. The water from the western sub-basin flows via overland and gutter flow to the emergency vehicle turn around, into a small "mini" pond or depression and then via a pipe to Pond B. The eastern sub-basin flows to a small "mini" pond or depression in the landscaping strip between the buildings, enters the "mini" pond via curb drops and then is conveyed to Pond B via a pipe.
