Official description
Description
The City has released its Comprehensive Speed Management Plan, a citywide, data-informed strategy to lower speed limits where allowed under state law and advance the City’s Vision Zero goal of eliminating traffic fatalities and serious injuries. Funded in part by a $680,000 federal Safe Streets and Roads for All grant, the plan used new state authorities, including Assembly Bill 43, to identify 679.1 centerline miles (over 20 percent of the City’s roadway network) eligible for potential speed limit reductions on safety corridors, high pedestrian and bicyclist activity corridors, business districts, and school zones. The City will now focus on implementation, subject to available funding and budget approval. Speed reductions will be paired with traffic calming, street design improvements, public outreach, and enforcement, and the City will monitor outcomes to ensure measurable safety improvements.
Tasks
What has been done?
- 2/2026
Create a Comprehensive Speed Management Plan
The Comprehensive Speed Management Plan identifies opportunities to reduce speed limits on over 20% of San Diego’s streets (679.1 centerline miles), made possible by recent changes in California law (e.g., Assembly Bills 43, 1938, and 382).
- 2/2023
The City obtained a U.S. Department of Transportation Safe Streets and Roads for All Grant
The City was selected by the United States Department of Transportation (USDOT) for a grant to create safe streets for all Americans. The Safe Streets and Roads for All Grant Program(SS4All) supports regional, local, and Tribal initiatives through competitive grants to prevent roadway deaths and serious injuries.
The $680,000 investment will help the City add a Comprehensive Speed Management Plan, Historically Disadvantaged Community Quick Build Program, and Slow Streets Program to the City's existing Vision Zero Strategy.
