Introduction&Intentions Ready Mix Concrete Ready mix concrete (RMC)is an essential building material for use in a variety of civil construction projects such as buildings, roads, bridges, and a variety of other structures. As the Wisconsin Department of Transportation (WisDOT)and a variety of other municipalities continue efforts to update and expand the Interstate 39/90 corridors in Dane County and beyond,the demand for a locally available and economical option for the production and distribution of RMC is critically important to on- time and on-budget projects to reduce the costs to tax payers and impacts on commuters for these projects. Based upon the onsite availability of some ingredient aggregate materials as well as the proximity to the proposed construction work,the Koshkonong Rd site offers an ideal location for the staging of a portable,temporary RMC plant to be used on the 139/90 and supporting municipal projects. Trierweiler Construction is requesting this conditional use permit on behalf of Forever Sandfill and Limestone Inc (Pit Operator& Lessee)and Joel Hougan (property owner)to operate a temporary RMC plant from May 1st 2017 to December 31st,2020 for projects awarded on the 139/90 expansion project as well as associated WisDOT and municipal road construction projects. Siting The site,consisting of Parcel 046/0611-094-9000-5 currently operates as a quarry/pit. It is proposed that the temporary RMC plant would be located in the southern 10 acres of the parcel. The conditional use permit area is approximately 0.87 acres in size,for the exact location please see the attached mapping. This would put the plant in the currently active portion of the pit and in close proximity to available material needed for batching RMC. The plant location would also follow proper setback requirements identified in Dane County Zoning Regulations for the site's A-1EX Exclusive Agriculture district zoning,which are discussed further in the following sections of this letter. Please see the attached mapping for exact setbacks. No building or structure beyond the mechanical equipment is proposed as part of the application. The RMC batch plant will be temporary and portable in nature so as to be located adjacent to where the aggregate production is occurring. Operation Description The proposed temporary/portable installation of a RMC plant would be utilized to mix concrete and load trucks to the 139/90 corridor expansion and associated WisDOT and municipal projects. While the exact number of employees varies between 5 and 15 on the RMC operations team. Operational periods will include generally day time operating hours(6:00 AM—8:00 PM)during week days and intermittent operation during weekends only as project demands necessitate. However,WisDOT does sometimes require nighttime work to limit impacts to drivers and to improve worker and driver safety. As such,for some segments of the project this Conditional Use Permit application requests 24-hour operation to accommodate the WisDOT 139/90 construction schedule. It should be worth mentioning that nighttime operation will only be utilized when mandated in the plans and proposals by WisDOT.
