Narrative:
We were assigned the midway nine departure from runway 4L at mdw airport. Upon review of the SID (on the ground) we were unable to decipher what its intent was; so I queried ATC. The procedure off 4L/right reads 'northbound departures assigned headings 360 clockwise through 080; climbing right turn to 2;400 ft heading 100 before proceeding on course.' lower on the plate in the routing window the initial altitude is listed as 3;000 ft. The initial climb instructions for 4L/right are absolutely undecipherable and ridiculous. I asked mdw tower (before our departure) what its intent was and they said that even they couldn't figure it out. This SID needs to be updated immediately to read in plain english. When an FAA facility that controls the airspace cannot understand the procedure something is wrong.
