When SB 375 (Steinberg) passed in 2008, it got a lot of press as a fundamental change in transportation and land use in California. The law would now require regional transportation investments that promote smart growth, with the state setting a metric target for each region to reduce greenhouse gas emissions through less driving.
The law had some immediate problems though, which I outlined after the first regional transportation plan under the law was unveiled in San Diego in 2011. Namely, SB 375 failed to compel any changes in local land use policies, which is where the ultimate authority for permitting new housing lies (the state’s local government lobby added a provision to the original bill that the sustainable transportation plans would not affect local government land use plans).
Now a new National Center for Sustainable Transportation study [PDF] that surveys local land use responses to SB 375 confirms this weak impact on local decision-making. The authors surveyed planning departments in all cities and counties in California regions subject to SB 375 and received 180 responses out of 474 contacted. The found:
A majority of both county and city planning managers report that SB 375 had little to no impact on actions by their city to adopt or strengthen the eight smart growth strategies asked about in the survey. Responses to this effect were especially pronounced for the use of urban growth boundaries and of ag-land and open space preservation, suggesting that cities may have been motivated to support such strategies for other reasons, perhaps even before SB 375.
To be sure, the study highlighted some positives from SB 375 for local governments, primarily related to increased information sharing among them:
At the same time, a majority of cities and counties report that SB 375 has led to increased communication among local governments and other actors about land use issues and has led them to participate more in the regional planning process.
But ultimately the law fails fundamentally to change local government behavior:
When asked about the eight smart growth land use strategies, relatively few local governments anticipate that SB 375 will have a substantial impact on their cities in terms of specific costs or benefits.
In the end, SB 375 will not be a game-changer by itself but a policy foundation upon which more meaningful legislation can build. Examples of more impactful legislation include SB 743 (Steinberg, 2013) and this year’s SB 35 (Wiener, 2017). SB 375 provides some conceptual underpinnings and data to support these newer laws. But without any direct tie to local decision-making, SB 375 as it currently stands will not by itself solve California’s land use and transportation challenges.
