Valencia was one of the first master planned communities,
They came up with this system of connecting cul de sac’s with biking/walking trails, something I have never seen repeated as well in any other community (even in later Valencia tracts).
It was done in the 70’s I guess it was not a practical way to lay out a housing tract as it used too much land so it did not get repeated is my guess
Anyway, give a home buyer the choice of a cul de sac or a networked street grid, in socal I bet they choose the cul de sac home 90% of the time all else being equal.
