We are returning this submittal with only a very cursory review. We note that the Pre-Submittal Checklist was not included with this submittal. Under this plan review process, the Sponsor's Design Engineer certifies that eacb submittal contains at least all the basic information necessary to determine whether or not the plans meet the applicable standards. This is intended to reduce the number of reviews conducted on a project, by ensuring a complete set of plans and calculations are submitted. Our comments are enclosed on that attached sheet. Please ensure that your next submittal is accompanied by the required checklist, and that all applicable items are included in the submittal. A copy of the checklist is enclosed for your use. Please contact Ed Parry at 456-3600 to schedule a Pre-Design Conference, so that the application and review process may continue, or to discuss any questions you may have about the process.

N.B.: Since this project is governed by the edition of the Spokane County Standards for Road and Sewer Construction (the "Standards", adopted 2 May 95, with an effective date of 15 May 95), these comments are general in nature, and do not represent a listing of all items which may not be in compliance with the Standards. The responsibility for ensuring compliance with the Standards lies solely with the Sponsor's Design Engineer. ALL DLSCItEPANCIES MUST BE ADDRESSED AND RESOLVED PRIOR TO PLAN ACCEPTANCE PROJECT DESIGN 2. Geotechnical Testing a. Soil Samples for Pavement design are typically taken from within the existing or proposed R/W for the road in question. The nearest point on McMillan Lane is located over 900 feet to the east of Barker Road; the sampling location appears to be at the intersection of McMillan Lane/Rio Grande Lane in Riverwalk 7th Addition - this point is over 1500 feet to the east of the Barker Road centerline. 3. Pavement Calcs: a. The Conditions of Approval for this plat indicate that Barker Road is a Major Arterial. The "Residential Arterial Matrix - Interim" is intended for roads classified no higher than a Collector Arterial. b. The Pavement calculations do not bear a P.E. stamp. 8. The plans indicate that various utilities will be relocated by others. The County will not be acquiring right of way for this to occur; if utilities are to be relocated, the Developer will need to demonstrate that he has obtained a commitment and a completion schedule from the utility companies to (a) obtain the necessary ea.sements and (b) to relocate the utilities prior to plan acceptance; these will need to include either the utility purveyor's agreement to relocate these utilities at no cost to the County when future road widening occurs, or a sketch indicating that the relocation will not interfere with the future R/W width indicated in the "Barker Road Special Section". As an alternative, the County Engineer will accept 6 feet of pavement widening on each side of the road, with a Type A curb. Driveway drops will be needed, as well as periodic drops to allow for drainage. The curb is needed in order to provide adequate traffic safety measures. Please call to discuss these alternatives prior to the next submittal 12. No prints of the plan mylars were submitted. Submittals are required to include 2 sets of prints.

Whipple, P.E. r 1 BaYker Road Improvements , RiveYwalk 7th Addition PUD Drainage Narrative ~ GENERAL e~ _J The Barker Road Improvements between Mission Avenue and Indiana Avenue on the east side of Barker Road are part of the Riverwalk 7th Addition PUD Plat. A separate drainage report, reviewed and accepted by Spkane County on September 26, 1996, has been prepared for the J residential development area of the Riverwak 7th Addition plat. The overall plat is a 28.0 acre development of 95 single family residential lots located north and east of the intersection of ~ Mission 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 north and west. A 1" to 400' scale 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 Barker ° Road Improvements as part of the Riverwalk 7th Addition plat. The storm drainage facilities on -J this project will be designed to dispose of runoff from a ten year design storm. This development i 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, Medlcal Lake, Reardon, Cheney and Rockford ~ J intensity curves was used, as well as the SCS iso-pluvial rainfall curves. Per direction from ~--Spokane County, the SCS curves have been further refined with the NOAA iso-pluvial 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 Q, ~ _ The Barker Road Improvements of the Riverwalk 7th Addition plat comprise an area from the intersection of Mission Avenue and Barker Road north to the Spokane River. At this time, widening improvements for the eastern one-half are proposed for the section of roadway between Mission Avenue and Indiana Avenue, by mutual agreement of the Spokane County Engineers, ~ the project sponsor, Pacific Properties, and Inland Pacific Engineering. Future improvements to ~ the section north of Indiana and east of the Barker Road centerline to the river will be addressed ~ at such time as Spokane County can acquire the appropriate right of way for full buildout and l Inland Pacific Engineering Company D 1 Barker Road Improvementst Drainage Report ~J . ~ utility relocation.l'herefore, this report addresses drainage design only within the aforementioned section between Mission Avenue and Indiana Avenue. The total width of the improvements is 75', of which 19' is original pavement and 17.5' is . additional paving width, for a total of 36.5' of pavement. There is 15' of additional right-of-way o beyond the existing 30'. The remaining 30' is composed of 5' of future acquisition area and 25' of sidewallc, drainage, utility and drainage easement. The Riverwalk 7th Addition subdivision is ~ located in the NE 1/4 of the S W 1/4 of Section 8, T. 25 N., R. 45 E., W.M. within Spokane County, Washington. . TOPOGRAPHY ~ The existing site sits along the south side of a low ridge sloping gently northbound towards Indiana Avenue from Mission Avenue. Within this section of roadway, the existing topography o was used to route storm drainage. 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 n ground absorption have occurred on this site. 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 J 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 gravellyglacial outwash material from a variety of igneous rock. Surface runoff is slow, and the hazard of erosion is slight. Spokane County Guidelines for BStormwater Manaaement indicate this to be a Soil Group Type B and pre-approved for drywell _ installation. ~ Hydrologic Soil Class f cation - B ~ a DRAINAGE NARRATIVE ~ Offsite Based upon the general geographic tendencies of this site, no offsite flows are expected for this ~ widening. ~ i - ~ _j Onsite ~ Inland Pacific Engineering Comparry D2 Barker Road Improvementst Drainage Report ~ ~ i t t ~ r ~ 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 Bazker Road Improvements were analyzed as one single basin, divided into 4 permanent sub-basins ( Z 1 through Z4), thereby allowing `208' treatment at intermittent locations to maintain a reasonable pond configuration within the confines of the drainage easement previously noted. ~ ~ ~ k~ e ~F B^ - G i • ~ V tl C G ' Inland Pacific Engineering Comparry D3 Barker Road Improvementst Drainage Report 4 . ~ a o~ ~ Table No. 1- Pond and Basin Summar,y E _ . . . ;.r:». . .,...:.r...,. . • . . . - . ~ . . . . ..:;:•::::::v.ti...' • . r:> . ~ ~ . }r :w::: r" r ":::4':•: . . . . : ~ r'a: ".•r::.::'_: • ~ " .r::: ~ :~::iw' ~ .........r.~.. . . }C::v::.".'~. • r . . ......r..r . . . ~ ~ . : - _ :•,y . - . , . ....y,.x,: ' ~ . . . . . . . ~ r • .

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. At times, the ponds are not ~ . ~ designed to be large enough to provide '208' storage for all of the upstream runoff. In such cases ` the excess is carried over to the next downstream pond or ponds, which can provide adequate , capacity for the identified flows. Curb Inlets and Catcb Basin Calculations ; It is necessary to check the adequacy of the curb drops, inlets or catch basins provided to divert ~ the runoff from the gutter into the '208' ponds. Should these be required, the curb inlet and catch basin calculation sheets included show the required lengths of curb openings, or single curb drops with lengths greater than 4.0', as well as the adequacy of the inlet grates or catch basin , ~ grates. For curb drops greater than 4.0', either multiple curb drops are added or the curb drops aze lengthened as required. -l DRAINAGE CALCULATIONS SUMMARY . ~ . Calculations have been included for Drainage Basin considerations such as Peak Flow, Time of Concentration, `208' sizing, drywell requirements, inlet sizing, curb inlets as well as culverts and ~ pipe flow, some of which are summarized below with the remaining calculations included in the appendix. Inland Pacific Engineering Company D4 Barker Road Improvementst Drainage Repon ~ e 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. p BASIN DESCRIPTIONS Basin Z 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 limited to 0.008 ftlft, and second, all ponds will be located beyond the future acquisition area to accomodate future widening.

Excavauon through surficial crushed rock revealed a brown silty gravel at all S test locations, which appeared to be native soiLs comprising the upper, weathered portion of the Valley gravels we have encountered across the Riverwalk development. Deeper excavadon wouid likely encounter cleaner gravels, samples of which would indicate greater pavement supgort characteristics, and thus a less conservative pavement section th.an the one currently proposed.
