I want to know the answer to the following question:
What is Houston's land use policies credited with producing?
All the background I'm provided with is that "Though some have blamed the city's low density, urban sprawl, and lack of pedestrian-friendliness on these policies, the city's land use has also been credited with having significant affordable housing, sparing Houston the worst effects of the 2008 real estate crisis.". Is that enough to answer the question?
