I was able to pull the ODP data but not the SID data, but I can give a fairly good guess as to whats going on. On the ODP, the controlling obstacle is a 2729-foot tower a few miles to the east of the runway. The initial climb is extended a bit more than usual in order to allow for a standard climb gradient when turning right (note that for turns other than to the right, a normal 400-foot turn is allowed). The WENDY and TRUPR are examples of Open SIDs, which have a route off the runway followed by radar vectors to a route. In these cases, the route off the runway is evaluated, but then the radar vector area gets no additional evaluation (other than MVA, etc.). SID evaluation begins again at the defined route. Because theres no SID evaluation required after the initial climb, the controlling obstacle for the ODP isnt considered. The minimum turning altitude for an RNAV SID is 500 feet above the runway, which would give you a turn at 1800 vs. the turn at 1900 on the ODP to keep a standard climb gradient and clear the tower. -LS
