PROJECT DESCRIPTION Introduction This evaluation was prepared to summarize the drainage system proposed for the Jackson Foods, Inc. Convenience Store project. This storm drainage evaluation will determine the type and size of water quality treatment devices that are acceptable to the City of Springfield. The project is located at 3375 Gateway Street in Springfield, Oregon which is situated in the northwest quarter of Section 22, Township 17 South, Range 3 West ofthe Willamette meridian. Existing Conditions The existing impervious area for the site consists of a service station/parking lot, and the pervious area for the site consists of a grassy field and landscaping. Runoff from the impervious area flows to the north to the municipal drainage system along Kruse Way (See Appendix A for Site Plan and Existing Drainage Basin Map). According to the Soils Survev of Lane County, Oregon, by the Natural Resource Conservation Service, the soil at the site is Malabon-Urban Land Complex (76) and is hydrologic soil group C/D. An infiltration test was conducted at the site on 4/30/2010 by Branch Engineering. The test consisted of three falling head tests, the measured average infiltration rate was ] 3 inches/hour (See Appendix B for Infiltration Test Report). Proposed Development The proposed development is to demolish the existing convenience store building and restrooms, and to construct a new Jackson Foods convenience store. The development will also add additional parking on the north side of the property. Proposed water quality treatment and stormwater destination for the new impervious area, drainage basin "A", is a rain garden. Dimensions for the proposed rain garden are approximately 75 feet in length, 16 feet wide, 3:1 side slopes, and 1.75 feet deep. Basin "A" is 12,390 square feet, which consists of landscaped areas to the east and south of the new building; however, this analysis will treat the entire development area as impervious surface. City of Springfield regulations state the 25-year storm event (4.8 in/24hr) must be used for destination requirements. Runoff from the basin "A" during the 25-year design storm was calculated to be 0.32 cfs. A safety factor of 2 was applied to the design infiltration rate by reducing the measured infiltration rate of 13 to 6.5 inches/hour. During the 25-year storm event, t.he depth of water in the infiltration basin is 1.05 feet. Appendix D contains storm runoff and infiltration basin calculations. The proposed runoff will receive water quality treatment by percolating through the rain garden topsoil layer. Percolation process will remove-pollutants throu\lh a<l~n, filtration, sedimentation and biodegradation. Date RecelveCf~ ( i@) Branch Engineering, Ine.

Thienes PO Box 25 Walterville, Oregon 97489 RE: INFILTRATION TEST RESULTS 3375 GATEWAY STREET WALTERVILLE, OREGON BRANCH ENGINEERING PROJECT No.10 063 Introduction Branch Engineering, Inc (BEl) has performed on-site testing for the purpose of assessing the rate of storm water infiltration of the near surface soil. The testing location was in the southeast section of the property at 3375 Gateway Street in Springfiled, Oregon. There was no indication of ponding or excessively wet surface conditions in the vacant lot. Site Exploration The scope of the field work consisted of advancing one (3) exploratory hand-auger boring on April 29, 2010 to a depth of 30 to 36-inches below surface grade, and presaturating the boring with one to two gallons of water. A plastic standpipe was inserted in the boring and the infiltration test was conducted on April 30, 2010; boring HA-2 was subsequently deepened an additional 2-feet. Infiltration testing was conducted in accordance with the 2008 City of Eugene Stormwater Management Manual for the falling head test method described in Section 2.4.2. The soil stratigraphy in the test boring was visually classified in accordance with the American Society of Testing and Materials (ASTM) Method 0-2488 and the upper 18 to 24-inches is described as a dark brown, soft silty clay 9ravelly fill/topsoil. The fill material has a low permeability but is underlain by native brown, silty clay/clayey silt to the maximum depth explored. Site Information Resources The following site investigation activities were performed and literature resources were reviewed for pertinent site information: . Review of the United States Department of the Interior Geological Survey (USGS) on- line Quadrangle Map, 7/1/1973. .

Three expioratory hand-auger boring were advanced in the northeast portion of the site. . Review of the Lane County area Web Soil Survey, United States Department of Agricultural (USDA) Natural Resources Conservation Service (NRCS). . Review of the USGS Geologic Map of Oregon, USGS 1991 . Review of Oregon Department of Water Resources Well Logs, see Appendix A. Subsurface Soils and GeoloQV The near surface soils within the project area consist of Pleistocene age unconsolidated to semi-consolidated fluvial sedimentary terrace deposits of clay, silt, sands and gravels. The NRCS Web Soil Survey maps the site within Malabon-Urban land complex, which is described as a well drained, silty and clayey alluvial terrace deposit. Nearby well logs from indicate silts, sand, gravel, and cobbles to a depth of 40 feet below ground surface. Observations after and during heavy rain event indicate that the site is well drained. Groundwater Ground water was not encountered in the site boring at the maximum exploration depth of 6-feet below ground surface. Well logs indicate a high water level of 8 feet below ground surface in November of 2005 and a low of 17 feet in August 2009. The ground water level at the site is expected to be influenced by the McKenzie River level approximately %-mile to the east. Infiltration TestinQ Based on our field-testing, the rate of fall in the water test column is .22 inches/minute (13 inches/hour). The rate of infiltration is expected to increase with depth as sand and gravel is expected to be present about 10-feet below ground surface. The analysis and infiltration test results are presented below. The rate of infiltration for a soil of given permeability is primarily dependent upon two factors, the area over which infiltration occurs and the pressure head. Using the following vadose zone equations, an estimated vertical hydraulic conductivity and rate of infiltration is presented in Table 1. A factor of safety has not been applied to the calculated hydraulic conductivities. Vi= Ki where: Vi is the rate of fall in the water height K is the hydraulic conductivity i = H", + LJ - hg L, i is the head loss L, is the depth of the wetting front Hw is median water height Branch Engineering, Inc.

Summary of Field Infiltration Test Results The final field test result is summarized below.

An infiltration facility shall not be founded in the fill on-site; we recommend that infiltration occur in the native soil strata located at a depth of approximately 24 to 3D-inches below surface grade.
