Large marijuana grow operation recommended for sprawling old factory in Muskegon Updated Dec 16, 2020; MUSKEGON, MI – A large-scale marijuana growing and processing operation could go into the vacant portion of the old Shaw-Walker factory in Muskegon, a section of which currently houses condos. The Muskegon Planning Commission has endorsed a request by the building’s owners to be zoned for all types of marijuana licensing. The building, which houses the Watermark Lofts condominiums, Coffee Factory restaurant and the Watermark 920 Conference Center, was already placed in a district that allows for marijuana retail sales. “That building has been vacant and falling apart slowly for a long time,” Muskegon Planning Director Mike Franzak told the planning commission earlier this month. “We’ve already seen part of it come down. I don’t know how much longer it has to go.”
