Finding a tenant for the former Oscar Mayer plant site would be enhanced by some upgrades and the Madison Common Council is being asked to apply for a 500-thousand-dollar grant from the Wisconsin Economic Development Corporation (WEDC) to finance the proposed enhancements to the property.   The money would be passed on to the new owners to help rebuild the electrical, water and sewer systems.  Production ceased at the Madison plant in 2017 after 98 years in business.  At its peak, four-thousand people worked at the facility in the 1970s.
