Today is a day of celebration for housing and transportation in California, with the possibility of more to come in the next two days. Yay!

But I want to caution about the alignment of housing with transit. It seems like a no-brainer, right? As I’ve long said, you can’t have affordable housing without effective transit, and you can’t have effective transit without widely available affordable and other housing. The problem I’m concerned about is that most of our transit system is oriented to arterial roadways (the semi-high speed, many-lane roads that are also called stroads because they don’t function well as streets or roads, and also called traffic sewers). Or in the case of rail transit, often uses old railroad corridors or freeway medians that make housing development difficult and probably unwise.

Research indicates that people, particularly kids, who live near freeways and arterials have much higher rates of asthma, and many other health problems, and shorter lifespans. Is that where we want low income families and kids living?

Apart from freeways, most traffic crashes happen on arterial roadways, and particularly at intersections of arterial roadways, and freeway on-ramps an off-ramps. Is this the hazard we want for low income families and kids?

I don’t have an answer for this challenge, but I often think it would be better to upzone everywhere (the next increment of development), so that additional housing can be built in places with better air quality and lower traffic violence. Maybe we should be fixing the arterials first, before we build housing along them. Yes, that delays the benefit of easy transit access to housing, but good transit in a poor living environment is just not what I want to see.
