Boston used to have just such a turn, though it was not required for
obstacles. "Left turn heading 140 degrees as soon as practical after
take off" was the wording for R/W 22, IIRC. The departure was still
"Terped" for a turn at 400 feet, however it was also terped for an
immediate turn. The early turn was not for obstacle avoidance, but
for noise or other issues.
St. Maarten departure off R/W 09 (?) is a visual procedure, last time
I saw it.

There used to be takeoff minimums where a turn was required as soon as
possible after takeoff for obstacle avoidance reasons. Anyone know if
any such still exist or if they have all been phased out?

I don't belive that "they" have moved the hill at St. Maarten yet. :-)
