Overview
- This week crews began installing nearly 3,000 new speed signs with the first reductions active in San Ysidro and Otay Mesa school zones.
- The city identified 679.1 centerline miles as candidates for slower limits, including 371.1 miles for 15–20 mph school zones and 189.6 miles on crash‑heavy corridors.
- New state laws let cities set lower posted speeds without the old engineering survey limits, allowing 15/20 mph near schools and up to 5 mph cuts on high‑risk corridors.
- The rollout is funded by a $2.4 million City Council allocation plus prior federal Safe Streets grant money and will move neighborhood by neighborhood as signs are replaced.
- City data show about 180 crashes a year cause death or serious injury and officials say reduced limits must be paired with traffic calming, enforcement and outreach to protect walkers, bike riders and older residents.
