Just like when you fill an application for a job or a program, they ask for your gender and race. Why? Because it helps schools get funding, and it allows for special accommodations. Maybe there is a need for signage in a different language or an interpreter. The same idea applies to architecture. When designing a building, a park, or a bus line. It would be negligent not to consider the types of people who would come in contact or utilize the structures being built. So, I definitely think that the separation and discrimination is intentional, because there is nothing that we can do in our society today without considering race.
There is an article called, “UT Austin’s School of Architecture Establishes Initiative on Race, Gender and the Built Environment” by Kathleen Stimpert. The article addresses the 21st century concern of design and planning. The article states, their “effort[s] aims to facilitate diversity among design and planning professionals and students, and foster innovation in teaching and research on race, gender and inequality in American cities” The University of Texas at Austin realizes the effect that culture and practices has on a city. So much, that they have opened a new department dedicated to researching those effects. I think that this goes to show how it would be very difficult to build a successful city without considering all the components.
