Last year, medical equipment maker Fresenius Kabi applied for and received a permit to expand its plant on Commonwealth Drive by 6,000 square feet. A few months later, the company realized that it actually needed more space, so it applied for and was granted conditional use approval to make it a 12,000 square foot expansion. That still wasn’t big enough. At its April 25 meeting, Cranberry’s Board of Supervisors heard testimony on the company’s proposal to make the addition even bigger – this time 18,500 square feet. After accepting public comment on the application, the Board agreed to consider final action at its May 2 meeting.
