That's definitely the case in Altadena which is a historically minority neighborhood. The cities south of Altadena like Pasadena and South Pasadena were redlined by real estate agents for decades after desegregation, which forced African Americans and Latinos to settle the foothills of the San Gabriel mountains at that wildland-urban boundary. Lots of people lost homes that have been in their families since the 60s and 70s. Who knows? If not for those policies, Pasadena could have been built denser and Altadena could have been miles of flat natural reserve that acts as a large firebreak where firefighters can easily fight the flames before they threaten thousands of structures, with frequent prescribed burns to keep the fuel load down. That's probably the real kind of conversation we should be having of municipalities easing housing restrictions to build denser and the state buying up large swathes of these wildland adjacent communities to create larger breaks between the hills and the houses.
