A key point. My subdivision is about 25% black, including both American blacks and immigrants from Africa. Another 25% or more is Latino, from several countries and Puerto Rico. Other immigrants: Russian and Ukrainian, Polish, Lebanese, Pakistani. And American white people, both from around here and Up North.
Everyone lives in reasonable amity ... an occasional parking or noise dispute ... house and lawn maintenance is pretty good to excellent, with no distinction by race or nationality. A few teenage-crime issues, again without a racial correlation.
It is not about race.
Our last neighborhood was not as diverse as yours but “people of color” there were friendly and familiar with the neighborhood values. (disclosier: My SIL is Hispanic which makes my grandchildren the same. I love them as much as the blond, blue eyed kids from my son and his Polish wife.
It comes down to class, and by that I mean degrees of it. Feral people of all races will consume the majority of government resources in local administration.
I grew up in a mixed race neighborhood. It never crossed my mind to treat my “colored” friends any different than anyone else. It is such a destructive and divisive thing for the left to turn race into a lie by which they snooker so many people into hating others.
