Pilots should know that ATC may request a climb gradient greater than the standard 200 FPNM in a DVA.
All DPs provide obstacle clearance if the aircraft crosses the end of the runway at least 35 feet AGL, climbs to 400 feet above airport elevation before turning, and climbs at least 200 FPNM unless a higher climb gradient is specified.
Operationally, lacking a DP and no note stating that a diverse departure is not authorized, you can safely depart by maintaining runway heading (mind the drift), climbing with a 200 FPNM gradient or better to 400 feet above runway elevation.
