--• \Tarrative fc�r Ramsey Co��nty Interim Use Permit �15 Larpenteur A�enue West Attachment C Interim Use Permit Request Nurpose and Background Ramsey County cuT-rently has bet�veen ?0�0 and 2_500 tons of construction debris stockpifed on County land at Kent Street and Larpenteur. Ramsey County discovered construction rubble debris whe.n excavating the Snelling Avenue pond as part of the Countv Road C reconstruction project. The pond site is located in the SE corner of Snelling Avenue and County Road C. The puipose of the pond is to treat storm water t-unoff prior to dischar�e into the adjacent wetland. Since construetion of the pond was a critical part of completing the project, and property for the pond limited, upon discovei-ing the consh�uclion debris, the County had no choice but to excavate the material. The County believes that reusing the material by crtishing and nlixinQ it int�o useful material is the most economical and earth friendly solution. � The debris contains concrete, bituminous, rock, and some metal pieces. The size of the material varies. The County desires to separate the metal from the debris and crush and mix the remaininQ mate�ial to make a blended and graded aaQregate that could be reused for road building�The other option would be t� haul it to a construction debris landfill which is expensive due to the haulinQ and dumpin� fees. Site Acti��ity Proposal The Cotmty proposes to complete the crushing and mixin� as soon �s app►-ovals are �ranted. The aoal will be to complete the work in late March, early ApiiL The �vork 4vi11 take a total of one week of which 2 to 3 days will be the actual crushina. The remaining time will be used to move in the portable material processing equipment, separate materials and then to demobilize. Once processed, the mateiial will be hauled off site for reuse and the metal sci-ap material ��ill be hauled to an appt-opriate disposal site. The site �vill be restored to the prior condition. The County will take measure to limit the dust and noise created by this activity. Since it is proposed to do this March/Aptil, most residential homes will still have their windows closed. The �uork would only take place during the normal �vork week �vith hours of opei-ation limited be.h�-een 7am and 7pm, within the City's requircd times. Water will be used to control dust durin� the operation.
