PROPERTY OWNER: 28th St Yard, LLC SUBJECT PROPERTY: Map 18-02-06, Tax Lot 1004 DESCRIPTION OF THE SUBJECT PROPERTY: The property subject to this application (the "Subject Property") has no physical address but is located at South 28th Street, south of F Street and abutting the Booth Kelly Haul Road (Tax Lot 1100) on the south and east boundaries of the Subject Property. It is more specifically identified as Map 18-02-06, Tax Lot 1004. The Subject Property is a 7.38-acre rectangular parcel formerly owned by Rosboro LLC. It is currently zoned Heavy Industrial, HI. Adjacent properties are also zoned HI, with the exception of the adjoining properties to the south and east which are zoned Low Density Residential. DESCRIPTION OF THE CURRENT USE: The Subject Property had been used by Rosboro LLC as a log storage yard with scales and a trailer loader for many years. There are currently no additional improvements to the site. DESCRIPTION OF PROPOSAL: 28th St Yard, LLC (the "Applicant") wishes to use the Subject Property, for storage of materials used in bridge construction, including large steel members, concrete members, wood lumber/timbers. The Applicant proposes to prepare the Subject Property for the storage of bridge construction materials by laying down a gravel base over a water permeable filter fabric. In addition, three 4 ft. wide infiltration trenches and an 11 ft. wide vegetated swale are proposed for the site. Accessory to the storage of bridge construction material, the Applicant wishes to use the Subject Property for light steel fabrication work, including use of welders, cutting torches and related fabrication equipment, for the assembly and disassembly of steel beams/components that will be stored on the Subject Property. The Applicant wishes to use and store a fork lift for moving materials on and off trucks. No other vehicles or motorized equipment are proposed to be stored on the Subject Property. The Applicant stipulates to the condition that no fluids, oil, or hazardous material will be stored on the Subject Property. Date Received: MAR 2 8 2011 Original submittal . . No structures are being proposed at this time. Access to the site will be via two entrances off of South 28'h Street. No curb cuts or closings are proposed. Proposed off-site improvements include the replacement of two existing 200 W LPS street lamps with new 400 W HPS lamps. Except for a north-flowing drainage ditch adjacent to South 28'h Street, there are no existing special site features related to site drainage. However, low berm constructed of compacted site and trench spoils is proposed on the east side of the property. This berm is to be not more than 1 1/2 ft. high, with side slopes of 10:1 or shallower. In general, site storm water will infiltrate at the site via infiltration trenches. However, for any surface runoff, the site drainage patterns will flow toward the west side of the Subject Property where the vegetated filter strip is proposed. Any surface water which is not intercepted at one of the infiltration trenches can flow to the vegetated filter strip which, in turn will connect to an existing culvert near the northwest property corner. The site soils will consist mainly of compacted gravel overlying undisturbed native soils. According to the USDA Web Soil Survey, the native soils consist of Salem gravelly silt loam (Soil Number 118, Hydrologic Group B), generally in the upper 2 to 5 ft overlying "bar run" gravels. Quantities of both excavated and imported fill material are estimated to be approximately 21,000 cubic yards each. The proposed imported fill consists of 3"- (0) and 1 y," - (0) quarry run gravels. The excavated material will be existing organic / deleterious materials down to suitablesubgrade. Any trees to be removed for the proposed work at the Subject Property would be only on the order of small shrubs and brush. No land is proposed to be dedicated to the City in the work at the Subject Property. There are no additional modifications, planning applications, MDS exceptions, or time extensions proposed or requested. Date Received: MAR 2 8 2011 Original Submittal ..

Storm Drainage Eva~uation Hamilton Construction Storage Yard Introduction This storm drainage evaluation was prepared to summarize the drainage system for the proposed storage yard for Hamilton Construction. This evaluation will review the proposed grading improvements and assess how stormwater will be managed. The proposed storage yard is located northeast of the intersection of South 28th Street and South Booth Kelly Road in Springfield, Oregon. The proposed project site is comprised of tax lot, TMI80206 TLI004. Existing Conditions According to USDA Web Soil Survey, this site consists of Salem gravelly silt loam (Soil Number: 118, Hydrologic Group: B). Salem gravelly silt loam falls into the well drained class. Typical water movement in the most restrictive layer is described as moderately high to high (0.57 to 1.98 in/hr) and increases to as much as 20 incheslhour as the underlying Gravel soils (Bar-Run) are encountered, generally within the upper 2- to 5- feet. South 28th Street borders the site to the west and South Booth Kelly Road to the south. The site was previously used to sort and store logs and has two gates onto S. 28th Street with a horseshoe-like roadway on site connecting them. Two built-up gravel access roads connect to the horseshoe-like roadway and run east to west. The area between the horseshoe-like roadway will be used to store construction materials including wood, steel, and concrete cast materials. We understand there is currently no public storm system serving this property. Stormwater runoff from the existing site either ponds up between the built-up gravel roads onsite or sheet flows toward the northwest and is collected in the ditch that parallels S 28th Street and outlets to the north. Onsite ponded water is likely due to many years of bark and wood debris storage. Proposed Site Conditions Due to the presence of fairly shallow well draining Bar-Run, stormwater will be infiltrated onsite. Three 4- foot wide infiltration trenches will be excavated onsite through any surficial soils down to the rapidly draining Bar-Run interface and backfilled with a free-draining material. A 2- foot thick well- draining gravel pad will be constructed over these trenches and used for stormwater retention. The site will be graded such to direct surface water to drain through the gravel pad and into these trenches. While we do not expect much in the form of runoff, any storm water runoff will sheet flow and shallow channel flow into a vegetated swale to be constructed along South 28th Street and ultimately connect to the existing culvert at the northwest property entrance. The vegetated swale will have 3H:1 V side slopes, check dams and be landscaped with appropriate vegetation and topsoil to allow for sedimentation and infiltration. Storm Water Conveyance System The following outlines the assumptions used in these calculations: Date Received: . MAR 2 S 2011 Original Submittal Storm Drainage Evaluation Hamilton Construction .
