This overflow path is located in a vegetated field and there is no physical channel along this reach. Accordingly, mobilization and transportation of significant amounts of sediment is unlikely. Further, average ‘channel’ velocities within the reach are very low for the 1% annual chance flood (1.2 ft/s; max of 3.8). Most XSs have channel velocities of under 1 ft/s. Finally, a collection pond is being constructed at the entrance to the culverts. The culvert inverts will be elevated above the pond bottom further discouraging transportation of sediment.

The site consists of 91 acres currently developed as a golf course. Stormwater runoff will be treated using drywells and/or gravel galleries for subsurface infiltration. These type of facilities will also be used to manage potential floodwaters, if needed. Because the existing Dishman-Mica roadway embankment is not considered a FEMA certified levee, a new levee will be constructed along the east side of the roadway. 1.2 Purpose The purpose of our services is to provide design recommendations for the proposed levee for conformance to 44 CFR 65.10 of the Code of Federal Regulations for certification by the Federal Emergency Management Agency (FEMA). 1.3 Scope Our services were requested by Mr. Bryan Walker of NAI Black. Mr. Walker authorized us to proceed on April 28, 2015. The scope of work agreed upon consisted of the following:  review of existing geotechnical data and reports for the development, if available  drill 6 penetration test borings at the site to a depth of 15 feet,  performing laboratory tests on samples obtained from the test pits,  classifying the soils and preparing boring logs, and  submitting a geotechnical report containing logs of the borings, results of our field investigation and laboratory testing, and our analyses, opinions, and recommendations relative to levee design and construction for conformance to FEMA standards. 1.4 Available Information We were provided a topographic survey for the project site by WCE. This topographic survey showed the existing roadways, existing structures, property lines, and existing ground surface elevation contours. This plan was prepared by WCE and was dated November 7, 2013. We performed a preliminary geotechnical evaluation for the property in December 2013. The results of that evaluation, along with our opinions and recommendations, are summarized in our Preliminary Geotechnical Evaluation dated December 31, 2013. In addition, we performed a geotechnical evaluation for the existing levee on the property to evaluate conformance to the FEMA standard. The results of that evaluation are summarized in our Geotechnical Evaluation report dated February 12, 2015. In conjunction with this evaluation, West Consultants, Inc. (WEST) has been contracted by NAI Black to provide a FEMA Conditional Letter of Map Revision submittal (CLOMR). They have provided Inland Pacific Engineering Company (IPEC) water surface elevations and velocity output from their revised RAS model to assist us in our evaluation. Geotechnical Evaluation Project No. 14-037A Proposed Levee 4403 South Dishman-Mica Road Spokane County, WA July 17, 2015 Inland Pacific Engineering Company Page 2 1.5 Locations and Elevations The borings were drilled at or near locations selected by us. The boring locations are shown on the Boring Location Map in Appendix A. The borings were staked by Whipple Consulting Engineers, Inc. (WCE). Ground surface elevations at the borings were provided by WCE. 2.0 RESULTS 2.1 Logs Log of Boring sheets indicating the vertical sequence of soils and materials encountered and groundwater observations are included in Appendix B. The strata changes were inferred from the changes in the penetration test samples and auger cuttings brought to the surface. Please note that the depths shown as changes between the strata are only approximate. The changes are likely transitions and the depths of changes vary between the borings. Geologic origins for each stratum are based on the soil type, available geologic maps, previous geotechnical reports for this and adjacent sites, and available common knowledge of the depositional history of the site. 2.2 Site Conditions The site was used as a golf course prior to our evaluation. The site is relatively level with some elevated golf greens and excavated areas for water hazards. The site is primarily grass-covered with scattered trees along the fairways and pine trees in the undeveloped area to the northwest. The clubhouse building is present at the southwest corner. The existing levee is on the east side of Chester Creek between Thorpe Road and Dishman-Mica Road. The new levee will extend from the north end of the existing levee north and west along Dishman-Mica Road. 2.3 Soils Geologic maps indicate the soils in this area consist primarily of alluvial and/or glacially deposited silts, clays, sands, and gravels. According to the Soil Survey of Spokane County, the site soils are classified by the Natural Resource Conservation Service (NRCS) as Narcisse silt loam and Endoaquolls and Fluvaquents. The native soils encountered in the borings were consistent with the NRCS data. Boring B-2 encountered existing fill in the upper 6 feet. The fill consisted of silty clay over silty sand. The remaining borings encountered 6 inches to 4 feet of topsoil at the surface. Below the topsoil or existing fill, the borings generally encountered water-deposited silty to clayey sands and/or poorly graded sands to their termination depths. Boring B-5 encountered alluvial lean clay between the 9 and 12-foot depth. Boring B-6 encountered lean below the 7-foot depth. 2.4 Penetration Resistances Penetration resistances (N-values) in the existing fill were 12 and 13 blows per foot (BPF). Penetration resistances in the silts and sands ranged from 7 to 37 BPF and averaged 19 BPF, indicating that these soils were loose to dense, but were typically medium dense. Penetration Geotechnical Evaluation Project No. 14-037A Proposed Levee 4403 South Dishman-Mica Road Spokane County, WA July 17, 2015 Inland Pacific Engineering Company Page 3 resistances in the clays ranged from 10 to 40 BPF indicating that these soils were rather stiff to hard in consistency. 2.5 Groundwater Groundwater was not encountered in any boring during or immediately after drilling. Groundwater is believed to currently exist at some depth below the termination depths of the borings. Based on our experience in the vicinity of the site, along with numerous test pits excavated previously on the site along with borings performed on the existing levee, it is our opinion that the portion of the creek along the existing levee is the beginning of the recharge section as evidenced by the typical lack of water in the creek further downstream. Also, the test pits previously excavated at the site east of the levee did not encounter groundwater. Well log data in the vicinity of the site indicate that groundwater is typically 50 to 80 feet below the surface. 2.6 Laboratory Testing We obtained soil samples from the borings during our site investigation. The tests performed included the following: 1. ASTM D 6913, Sieve Analysis 2. ASTM D 4318, Atterberg Limits’ These tests were used to aid in classifying the soils and in the engineering analyses and formulation of engineering opinions and recommendations. Attached are data sheets summarizing the tests performed. 3.0 ANALYSIS AND RECOMMENDATIONS 3.1 Discussion Based on the data obtained from the recent and previous borings and/or test pits, it is our opinion that a new levee can be constructed adjacent to the Dishman-Mica Road that conforms to the FEMA standard. The following sections provide recommendations for construction of a levee that meets the standard based on EM 1110-2-1913, “Design and Construction of Levees, by the US Corps of Engineers dated April 30, 2000. Certification of the levee can be completed after construction has been completed. 3.2 Site Preparation We recommend that any existing topsoil, root zone, and existing fill be excavated and removed from the levee footprint area. After these soils have been removed, we recommend surface compacting the exposed soils prior to placing structural fill for the embankment. Structural fill should be placed in 6- to 8-inch-thick loose lifts at or near optimum moisture content and compacted to a minimum of 92 percent of the maximum dry density determined in accordance with ASTM D 1557 (modified Proctor). Geotechnical Evaluation Project No. 14-037A Proposed Levee 4403 South Dishman-Mica Road Spokane County, WA July 17, 2015 Inland Pacific Engineering Company Page 4 In areas where structural fill is placed on the existing Dishman-Mica Road embankment, we recommend that the fill be benched into the slope. We recommend a maximum bench height of 4 feet and a minimum bench width equal to twice the bench height. At this time, we recommend a maximum slope angle of 3:1 (H:V) for permanent slopes excavated in the native soils or embankment fills using the native soils as structural fill. The site soils which will be reused as backfill or fill are likely to be dry of optimum moisture content. These soils may require wetting to achieve adequate compaction. Backfills and fills should be placed in thin lifts not exceeding 6 to 8 inches. Most of the on-site native soils and much of the existing fill can be used as structural fill provided particles larger than six inches and all debris are removed. We recommend in-place density tests be performed on all embankment fill placed. We recommend at least one test for every 100 cubic yards of fill placed in the levee embankment with at least one test for every 2 feet of fill placed. If site grading and construction are anticipated during cold weather, we recommend that good winter construction practices be observed. All snow and ice should be removed from excavated and fill areas prior to additional earthwork or construction. No fill should be placed on soils which have frozen or contain frozen material. Frozen soils should not be used as backfill or fill. 3.3 Freeboard We were provided 100-year flood elevations by WEST. They provided us a plan view of the levee with flood elevations at 6 locations starting at the existing levee at the bridge on Dishman- Mica Road and ending at the northwest corner of the property near Wilbur Road. The elevations ranged from 2010.4 at the existing levee to 2008.1 at the north end. Please refer to the WEST report for a complete summary of the floodplain analysis. According to 44 CFR Section 65.10(b)(1), an additional 1 foot of freeboard is required within 100 feet of bridge structures. The freeboard requirement for the Dishman-Mica Road bridge is adequate. 3.4 Closures There are no penetrations of the levee proposed so closure devices are not required. 3.5 Embankment Protection The levee will tie in to the Dishman-Mica Road embankment along its entire length which will provide creekside erosion protection to the top of the roadway embankment. For those portions of the levee above this elevation (if needed), it is our opinion that vegetative cover (grasses) would be suitable based on the flow velocities provided by WEST. Geotechnical Evaluation Project No. 14-037A Proposed Levee 4403 South Dishman-Mica Road Spokane County, WA July 17, 2015 Inland Pacific Engineering Company Page 5 3.6 Embankment and Foundation Stability We recommend that the new levee be constructed with maximum 3:1 (H:V) slopes for stability. We recommend a minimum crown width of 8 feet. We recommend that the levee embankment materials consist of a granular soil having 10 to 30 percent by weight passing a 200 sieve to reduce the permeability and limit seepage. We have assumed that on-site soils will be used as borrow to construct the embankment. We evaluated the embankment and foundation stability for conditions described in EM 1110-2- 1913, “Design and Construction of Levees, by the US Corps of Engineers dated April 30, 2000, Chapter 6. We analyzed the levee embankment for the following cases: 1. CASE I, End of construction. 2. CASE II: Sudden drawdown. 3. CASE III: Steady state seepage from full flood stage. We performed slope stability analyses for each case. We analyzed the levee embankment with 3:1 slopes. For our analyses, we used XSTABL software which is based on a software program developed at Purdue University. For these cases, we calculated the minimum factors of safety as shown in the following table. CASE Minimum Factor of Safety I 2.45 II 1.86 III 2.15 For stability, a minimum factor of safety of 1.5 is generally considered acceptable. Based on this analysis, it is our opinion that the levee will be stable with respect to global slope stability provided the recommendations of this report are followed. 3.7 Settlement The average depth of fill will be approximately 5 to 6 feet. This would result in a loading increase of approximately 750 pounds per square foot (psf) on the bearing soils. Based on the data obtained from the borings, the levee will be constructed above loose to medium dense sands or sandy silts. Settlement in these soils will generally occur shortly after construction. Given the stiff condition of the clays at depth, we do not anticipate any significant settlement in these layers. We did analyze the lean clay layer encountered in Boring B-5 with a 6-foot raise in grade to maintain minimum freeboard. For our analysis, we used a unit weight of 125 pounds per cubic foot (pcf) for the embankment fill soils and a compression index of 0.06 for the lean clay and assumed total saturation of the clay layer. Based on these parameters, we estimated the settlement to be less than 0.5 inches. Geotechnical Evaluation Project No. 14-037A Proposed Levee 4403 South Dishman-Mica Road Spokane County, WA July 17, 2015 Inland Pacific Engineering Company Page 6 3.8 Interior Drainage Interior drainage systems have been designed by WCE. We understand that these systems will include detention ponds with multiple drywells to control flood waters and infiltrate them into the ground. Please refer to the WCE report for a comprehensive description of the interior drainage system. 3.9 Operation Plans The Operation Plan will be prepared as part of the final levee certification. 3.10 Maintenance Plan The Maintenance Plan will be prepared as part of the final levee certification. 4.0 PROCEDURES 4.1 Drilling and Sampling The borings were completed on May 21, 2015 using a truck-mounted drill rig operated by an independent firm working under subcontract to IPEC. A geotechnical engineer from our firm continuously observed the borings and logged the surface and subsurface conditions. After we logged the borings, they were abandoned in accordance with state requirements. 4.2 Soil Classification The soils encountered in the borings were visually and manually classified in the field by our field personnel in accordance with ASTM D 2488, “Description and Identification of Soils (Visual- Manual Procedures)”. 5.0 GENERAL RECOMMENDATIONS 5.1 Basis of Recommendations The analyses and recommendations submitted in this report are based on the data obtained from the borings performed at the locations indicated on the Boring Location Map in Appendix A. It should be recognized that the explorations performed for this evaluation reveal subsurface conditions only at discreet locations across the project site and that actual conditions in other areas could vary. Furthermore, the nature and extent of any such variations would not become evident until additional explorations are performed or until construction activities have begun. If significant variations are observed at that time, we may need to modify our conclusions and recommendations contained in this report to reflect the actual site conditions. 5.2 Groundwater Fluctuations We made water level observations in the borings at the times and conditions stated on the boring logs. These data were interpreted in the text of this report. The period of observation was relatively short and fluctuation in the groundwater level may occur due to rainfall, flooding, irrigation, spring APPENDIX A SITE LOCATION MAP, NRCS MAP, BORING LOCATION MAP FIGURE 1 Site Location Map Project No. 14-037A July 17, 2015 Proposed Levee 4403 South Dishman-Mica Road Spokane Valley, WA FIGURE 2 NRCS Map Project No. 14-037A July 17, 2015 Proposed Levee 4403 South Dishman-Mica Road Spokane Valley, WA FIGURE 3 Boring Location Map Project No. 14-037A July 17, 2015 Proposed Levee 4403 South Dishman-Mica Road Spokane Valley, WA APPENDIX B LOGS OF BORINGS, DECRIPTIVE TERMINOLOGY SS SS SS SS SS 8-10(18) 3-10(13) 10-15(25) 17-18(35) 14-8(22)11 7 (SC) CLAYEY SAND, fine grained, with roots, dark gray, moist to wet.
