L Lafayette, California, has announced plans to move major infrastructure projects forward in the 2026-2027 fiscal year and a five-year roadmap stretching through 2031, outlining how the city will spend transportation, utility, and development funds to maintain and modernize core infrastructure. The city completed major upgrades in 2025, including repaving key stretches of St. Mary’s Road and Mt. Diablo Boulevard, adding curb ramps, bus stops, drainage improvements, guardrails, and high-friction safety surfacing. The City Council is set to vote on the plan as part of its June budget adoption.
