The river flats below Bay City have always been working ground — barge water, rail beds, wide gravel yards backing onto the Saginaw. Alliance Site Services LLC keeps that kind of property in shape all year: mowing and trimming through the green months, then plowing, shoveling walks and salting once the ground goes hard. Summer here means broad open turf that jumps after a warm rain off the bay. Winter means the same acreage, only white, waiting to be cut into lanes before daylight. Different tools, same ambition — pavement you can cross and grass you can walk on.
