Geotechnical Engineering Evaluation (and sieve data) Klahaya Swim & Tennis Club, August 28, 2007 Geologic Map of the Edmonds East Quadrangle Minard, James P., 1983 2005 DOE Manual REIVED Section 3.3.6 MAR 31 2013 DEVELOPMENT SERVICES CTR. Dear Mr. Echelbarger: CITY OF EDMONDS In accordance with your request, Earth Solutions NW, LLC (ESNW) has prepared this letter and evaluation of infiltration characteristics of the native sand deposits throughout the site. ESNW sampled, logged, and analyzed two test pits, as well as reviewed the referenced geotechnical engineering evaluation performed by PanGEO, Inc. It is our understanding that infiltration methods, such as infiltration trenches, may be utilized for the proposed single family residence at the subject site: The referenced geologic map identifies area soils to be advance outwash (Qva). The soil conditions observed at the test pit locations are consistent with the geologic map designation. Sand deposits encountered at the test excavations throughout the site possess good infiltration characteristics, and are suitable for the proposed infiltration system. The approximate locations of the test pit excavations are provided on the attached site plan. Test pit logs and sieve analysis data are also provided as an attachment to this letter. 1805 - 136th Place N.F.., Suite 201 • Bellevue, WA 98005 • (425) 449-4704 • FAX (425) 449-4711 STmEET FILE Echelbarger Investments, LLC ES-2715 February 25, 2013 Page 2 Test Excavations Test pits TP-1 and TP-2 were excavated at representative locations within the site (see attached site plan). The excavations were advanced to depths of approximately seven feet below existing grade. Soils were observed to consist of poorly graded sand with gravel deposits (USDA Classification — Gravelly Coarse Sand). No groundwater was encountered in the test excavations (February 2013). Sieve data from representative soil samples collected at the test excavation sites are attached to this letter. Based on existing grade and our understanding of the proposed development plans, the test excavations were advanced sufficiently deep to adequately characterize soil and groundwater conditions to a depth of at least three feet below future infiltration facilities. Soil throughout the test pit excavations were uniform with respect to the sand deposits, and no groundwater was observed. Given the absence of groundwater in the test excavations, and given the time of the testing (February 2013), groundwater related influences to the performance of the proposed infiltration system are not expected. Design Infiltration Rate For design, the long term infiltration rate was evaluated based on the criteria specified in the referenced 2005 DOE Manual (Section 3.3.6). Table 3.8 of the referenced DOE Manual provides criteria for estimating the long term infiltration rate based on sieve analysis data and the D 10 particle size. As specified in the manual, Table 3.8 is best suited for sand deposits, and therefore is acceptable for use at the subject property. Based on the sieve analysis data from soil samples collected at test pits TP-1 and TP-2, the D to particle size of the sand deposits is approximately 0.19 to 0.32 millimeters. Based on interpolation of the Table 3.8 values, the D to values of the tested soils would correspond to long term infiltration rates of approximately 3.25 in./hr. to 7.00 in./hr. Based on the sieve analysis testing and observation of soil conditions by the undersigned during the field exploration, the criteria specified in Table 3.8 of the referenced DOE Manual is an acceptable method for deriving a long term infiltration rate. Based on review of the soil data and referenced DOE Manual (and the overall uniformity of the sand and gravel soils), the following long term infiltration rate is recommended for design: e Recommended Long Term Infiltration Rate The above recommended infiltration rate is relatively previous interpolation of the Table 3.8 values. The observe the excavations for the proposed infiltration time of construction. 4.0 in./hr. conservative, in our opinion, given the geotechnical engineer, however, should system to confirm soil conditions at the Earth Solutions NW, LLC 11 Echelbarger Investments, LLC ES-2715 February 25, 2013 Page 3 We trust this letter meets your current needs,.: Should you require additional information, or have questions, please call.

They are not intended to be measures of the facility's required condition at all times between inspections. In other words, exceedence of these conditions at any time between inspections and/or maintenance does not automatically constitute a violation of these standards. However, based upon inspection observations, the inspection and maintenance schedules shall be adjusted to minimize the length of time that a facility is in a condition that requires a maintenance action.

Based on existing grade and our understanding of the proposed development plans, the test excavations were advanced sufficiently deep to adequately characterize soil and groundwater ' conditions to a depth of at least three feet below future infiltration facilities. Soil throughout the test pit excavations were uniform with respect to the sand deposits, and no groundwater was observed. Given the absence of groundwater in the test excavations, and given the time of the ' testing (February 2013), groundwater related influences to the performance of the proposed infiltration system are not expected. Design Infiltration Rate For design, the long term infiltration rate was evaluated based on the criteria specified in the ' referenced 2005 DOE Manual (Section 3.3.6). Table 3.8 of the referenced DOE Manual provides criteria for estimating the long term infiltration rate based on sieve analysis data and the D 10 particle size. As specified in the manual, Table 3.8 is best suited for sand deposits, and therefore is acceptable for use at the subject property. Based on the sieve analysis data from soil samples collected at test pits TP-1 and TP-2, the D 10 particle size of the sand deposits is approximately 0.19 to 0.32 millimeters. Based on interpolation of the Table 3.8 ' values, the D 10 values of the tested soils would correspond to long term infiltration rates of approximately 3.25 in./hr. to 7.00 in./hr. ' Based on the sieve analysis testing and observation of soil conditions by the undersigned during the field exploration, the criteria specified in Table 3.8 of the referenced DOE Manual is an acceptable method for deriving a long term infiltration rate. Based on review of the soil data ' and referenced DOE Manual (and the overall uniformity of the sand and gravel soils), the following long term infiltration rate is recommended for design: Recommended Long Term Infiltration Rate The above recommended infiltration rate is relatively 4.0 in./hr.
