All design deviations have been approved by the Spokane County Engineer. I approve these plans (calculations) for construction. This report has been prepared by Susan K. Murphy of Inland Pacific Engineering Company under the direction of the undersigned professional engineer whose al and signature appear hereon. . , 9t GNAL~ EXPIRE 9 Todd R. Wh p e, i Riverwalk 9th Addition PUD Drainage Narrative GENERAL Riverwalk 9th Addition PUD Plat is a 10.89 acre development of 38 single family residential lots and 5 tract areas located north and east of the intersection of Indiana Avenue and Barker Road, within Spokane County, Washington. The site is currently vacant with field grass, alfalfa and fallow fields as the predominant land cover and vegetation. Single family residential ~ development lies directly to the south and east. A vicinity and location map have been included within the technical section of this document. PURPOSE The purpose of this report is to determine the extent of storm drainage facilities which will be required to dispose of the increase in stormwater runoff created by the development of the Riverwalk 9th Addition plat. The storm drainage facilities on this project will be designed to dispose of runoff from a ten year design storm, as required by the Spokane County Guidelines for Stormwater Management, though calculations are also included to verify that the facilities also generally contain the 50-year 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 curves was used, as well as the SCS iso-pluvial rainfall curves. ANALYSIS METHODOLOGY Per the Spokane County Guidelines for Stormwater Management, 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 This phase of the Riverwalk 9th Addition plat comprises 38 lots of the approved 393 lots in the approved preliminary plat and SEPA documents. The Riverwalk 9th Addition subdivision is located in the NE 1/4 of the SW 1/4 of Section 8, T. 25 N., R. 45 E., W.M. within Spokane County, Washington. TOPOGRAPHY The existing site naturally drains to the north and west, sloping gently towards the Spokane River from Indiana Avenue. Within the plat the natural topography was used as much as possible to Inland Pacific Engineering Company D1 Rivenvalk 9th Addition Drainage Report , route storm drainage. However, due to the flat slopes and the County's minimum requirements for slope, the roadway profiles have been forced down to facilitate drainage by localizing low spots for pond placement. Due to the flat slopes encountered, no concentrated pre-existing flows were observed nor were there any signs that anything other than sheet flow and ground absorption have occurred on this site. The general slopes within this plat vary from flat to nearly flat with the maximum existing slope at 0.01 ft./ft. Generally, the area within this platted portion of the overall preliminary plat would be characterized as flat. For development purposes as stated 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 one type of soils within the Class B type. This soil type is described as follows. GgA - Garrison gravelly loam, 0 to 5 percent slopes: Soils within this soil type are some what excessively drained soils formed in gravelly glacial outwash material from a variety of igneous rock. Surface runoff is slow, and the hazard of erosion is slight. Spokane County Guidelines for Starmwater Mana em indicate this to be a Soil Group Type B and pre-approved for drywell installation. Hydrologic Soil Classification - B DRAINAGE NARRA TIVE Offsite Based upon the general geographic tendencies of this site, no appreciable amounts of offsite flows are expected for this phase. Onsite As this plat is within the aquifer sensitive area of Spokane County 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 Riverwalk 9th Addition plat was divided into 11 permanent sub-basins ( A through K). Although there are 11 basins, these basins have been combined where practical to utilize the same pond. Table 1 lists the basins and pond combinations for easy reference.

These facilities capture upstream stormwater runoff from the impervious street surface and direct the runoff into grassy '208' ponds. As shown on the '208' calculation worksheets included, the '208' storage volume provided is adequate to perform '208' treatment for the runoff created by the first half inch of rainfall. Curb Inlets and Catch Basin Calculations _ It is necessary to check the adequacy of the curb inlets, inlets or catch basins provided to divert the runoff from the gutter into the '208' ponds. Should these be required, the curb inlet calculation sheets included show the required lengths of curb openings, as well as the adequacy of the inlet grates or catch basin grates. For curb inlets greater than 4.0', either multiple curb inlets are added or the curb inlets aze lengthened as required. DRAINAGE CALCULATIONS SUMMARY Calculations have been included for Drainage Basin considerations such as Peak Flow, Time of Concentration, "208" sizing, drywell requirements, inlet sizing and curb inlets, as well as culverts and pipe flows, some of which are summarized below with the remaining calculations included in the appendix. Inlarul Pacifte Engineering Company D3 Riverwalk 9th Addition Druinage Report , and pipe flows, some of which are summarized below with the remaining calculations included in the appendix. Within the calculation section and where it has been determined necessary for clarity, several sketches, as well as details from the plans have been incorporated to demonstrate assumptions and conclusions. BASIN DESCRIPTIONS Basins A through K ' Within this plat, and due to the general geographic features, several basic assumptions were followed and can be used to describe each basin. First, due to the relative flatness of the plat and project vicinity, minimum road grade is lunited to 0.005 ft./ft; second, large tract ponds if practical will be used in the open space azea; third, all other ponds will be of the lot pond configuration; fourth, that where practical, drywells will be minimized by combining basins and providing piping between ponds. All of these steps have been used in various basins throughout the drainage design ofthis.project. There are four basins, L, M, N, and O which have been analyzed in the predeveloped and developed condition to verify that the developed flow is less than the predeveloped flow. The four basins are backyard areas whose natural slope directs flow away from the front yazds, and is therefore not included in any of the other basins. They have been isolated and labeled on the basin map, and due to landscaping presumed to be installed in the developed condition, the runoff will be lower than the predeveloped state. No treatment is required in this condition.

SPO~E RE: Results of Soil Classification Testing Riverwalk 9' Addition Please find enclosed the results of sqils classification testing performed by Inla.nd Pacific Engineering Company, Inc. (IPEC) bn three soil samples obtained from the above referenced residential development. Soil Sample # S-1 was obtained froic Harmony Lane, approximate Sta. 28+78, approximately 16 feet left of proposed centerline, at 1 5 to 2 feet below existing adjacent grades. Soil Sample # S-2 was obtained from Harmony Lane, Ipproximate Sta. 32+28, approximately 16 feet left of proposed centerline, at 1.2 to 2 feet below existing grades. Soil Sample # S-3 was obtained from Riverway Lane, approximate Sta. 1+34, approkiinately 18 feet left of proposed centerline, at 1.5 to 2 feet below existing adjacent gr des at time of sampling. The sa.mple locations were obta.ined by use of a hip cha.in and hand-held ompass, with the northern curb line of Indiana at the intersection of Harmony Lane and I diana Avenue used as horizontal control, and should be considered accurate to the degree i plied by the methods used. We certify herein that the samples tested were obtained by members o our staff from the approximate locations stated above, and that based on the data enclosed, the USCS soil classification of GM is correct for a11 three of the samples tested.
