heavy rainfall events. This intersection drains a sizable light industrial area west of <br /> Bertelsen Rd. from both 13th Ave. And Interior St. The area is low -lying and <br /> adjacent to wetlands associated with the Willow Creek basin. The only stormwater <br /> structures draining this area are two curb inlets ( #54457 and 54523) near the cul -de- <br /> sac at the north end of Interior. These inlets drain into a 36" pipe, which runs west to <br /> the 48" pipe that runs north to Amazon Creek. In heavy rainfall events, the piped <br /> system surcharges and the high ground water causes sheet flow off of the properties <br /> and onto the street. The combined effects create considerable flooding at times. <br /> Engineering records dating back to the time of construction of these streets indicate <br /> that the street surface level may lie below the HGL. <br /> Recommended Solution: Have Engineering analyze this system as a whole and design <br /> and construct corrective measures to increase capacity. <br /> Status: Maintenance is planning to install catch basins in the intersection and connect <br /> to the existing system primarily as a measure to facilitate drainage following a major <br /> storm event, though this won't help during surcharge conditions. WRT is including <br /> this area in the Basin Study. <br /> 14. Location: Lane County Solid Waste Central Receiving Station (CRS), Glenwood <br /> Nature of Project: Stormwater Waste Disposal Facility <br /> The design and construction of a pilot facility would be based on data and specifi- <br /> cations provided by Maintenance Planning. Such a facility would consist of an <br /> adequate, low -tech dumping station which incorporates a sloped dumping/drainage <br /> bed and liquids detention structure with an adjoining space for stockpiling of the solid <br /> waste material. On such a facility the vactor waste would be dumped, drained and <br /> pushed or loaded into the stockpile where it would then be in a sufficiently dewatered <br /> state for transport to and acceptance at the Short Mtn. or other solid waste landfill site. <br /> The vactor liquids would be pre- treated by means of a sedimentation sump and then <br /> piped to the wastewater system. <br /> Status `96: Feasibility study for a regional facility at either the MWMC drying beds <br /> on Awbrey Lane or near the Lane Co. solid waste CRS in Glenwood was completed. <br /> Lane County staff decided to build and operate the facility at Glenwood. The vactor <br /> waste characterization study has been completed. A facility optimization and cost <br /> analysis has been submitted by Eugene Public Works staff to the County Engineer for <br /> review by the County Commissioners. Lane County intends to take the lead in the <br /> facility design and construction. The facility is scheduled to be completed and <br /> operational by Fall of 1996. <br /> Status `97: The plans are completed by Lane Co. PW Engineering and currently <br /> under review at the PIC. The minor modification to the conditional use permit for <br /> the Glenwood CRS has been approved and DEQ has submitted a letter of <br /> concurrence. Intergovernmental agreement currently being drafted. Completion <br /> date is slated for July- August, 1997. <br /> / <br /> 97rehab.etn 3/97 bne <br />
