First, "the blind" and "the deaf" is not really the language you want to be going for, here. "d/Deaf people" or "blind people" is a much less potentially offensive or problematic way to say it.
Second, many blind people (myself included) believe that schools for "the blind" are extremely damaging and limit student's independence and ability to learn within the community. Whereas a Deaf child has a specific reason to benefit from attending a Deaf school (everyone speaks their language), a child who is blind but not deafblind receives no particular benefit being taught in a non-inclusive school, and will typically face needless challenges such as lower educational standards, limitation on freedom of movement, lack of opportunity to socialize with sighted peers, etc.
All that aside, even where schools for blind students DO exist, structural modifications should never be made. In the real world a blind student will not encounter structural modifications suited to them, and as such these should not be included in this sheltered "preworld" of disabled-only schools.
Real-world colleges don't have "specially textured walls": you take your cane out and you travel like everyone else. At best, the only important feature to blind users in a building is braille numbering/lettering on signage, but that is not so much structural changes as what you fill that structure up with.
Everything else is frivolous material you are using to gain points with your teachers and is almost certain to be based on ableist assumptions and serving the function of further perpetuating myths about blindness and other disabilities.
