You probably need to split District 4 and 9 on a vertical axis instead of a horizontal one.
Also, maybe make the Houston district more Hispanic?
Dists 3 and 4 both are packed with too many Hispanics to avoid a VRA challenge. Those two plus dist 9 would be better if rearranged to provide similar HVAPs.
The case law on this is quite a bit less clear. The specific rumors regarding the south Texas region, as far as I can tell, originate from a Reagan era justice department memo. But, 90%+ VAP legislative districts have existed and been upheld on a frequent basis, including by Justice Breyer when Boston minorities were racked and packed into such districts.
