Airspace Structure; Procedure
Aircraft X was a CXO departure climbing inside of I90 airspace on the LCH departure.  I90 switched him to me climbing to 160 with 2 WAPPL arrivals descending on top of him.  My D-Side called over to DAS to point the departure out and they referenced Aircraft Y and Aircraft Z on the [Arrival].   I called over to Approach to tell them I was delaying him at 160 for the arrivals.  The I90 Controller told me to put him on a 120 heading to avoid the arrivals in which I did.  This departure is not procedurally separated from these WAPPL arrivals and we can't climb the CXO/DWH departures with the lack of separation.  The I90 Controller continued to descend the arrivals through the altitudes of Aircraft X.  Once they were cleared inside of approach airspace I climbed the departure.  This to my knowledge happens on a daily basis and is a very unsafe condition.Look into a procedure change on the north satellite departures going out the Trios gate to.
ZHU Controller describes scenario where a departure is taken off its route to allow its climb; while it comes into conflict with two arrivals.  The Controller describes the routes are not able to climb or descend traffic laterally but controllers do this everyday.
