John Amos of Sandy is due in court Nov. 29 in connection with the incident April 18.
Police say they found 52-year-old Thayne Hansen slumped over with his face submerged in water inside the drain at the Draper Spectrum shopping center.
He was pronounced dead at a hospital.
Police say Amos used a handicap ramp that's not meant for cars as a shortcut into the parking lot and apparently didn't see Hansen when he drove over the drain.
Negligent homicide is a misdemeanor charge punishable by up to a year in jail.
Amos didn't immediately return a call seeking comment on Tuesday.
