I wonder if the reason is simply that departure in that direction
doesn't meet 200 ft/NM at some distance out, maybe 10 or 20 miles, but
the FAA has not got around to doing the required survey to arrive at a
specified departure gradient requirement so they just declare it NA
until someday they get around to it. I believe that you have to be
able to have obstacle clearance with 200 ft/NM out to 22 NM from the
runway before you have to have a specified gradient other than default,
which gets you to 4400 HAA.


The 200 ft/nm applies to departure procedures that do not otherwise
specify a minimum climb gradient. Absent a departure procedure the
pilot is free to make up any procedure he sees fit. The FAA has not
come close to visiting every airport and creating DPs for every runway
out there.

That is misleading. For a runway at an IFR airport that has NA, they
have looked at it. Shame on you for not knowing that.
