California's Infrastructure Earns a C-Minus — Roads and Drinking Water Are Failing

Read Full Article

The American Society of Civil Engineers (ASCE) released its 2025 Report Card for California's Infrastructure in December 2025. The overall grade: C-minus — unchanged from 2019. The state's most critical systems are deteriorating faster than they are being repaired.

Category Grades

CategoryGradeKey Finding
RoadsDNearly 30% in poor condition (national avg 22%)
Drinking WaterD+Downgraded from C in 2019; 85% of utilities rely on components past design life
BridgesC-65% of 25,392 bridges older than 50-year design life; 1,500+ in poor condition
StormwaterDChronically underfunded, undersized for extreme weather
PortsBHighest grade — recent investment paying off
RailBStrong performance from recent electrification projects

Drinking Water: The Quiet Crisis

The drinking water downgrade from C to D+ is the most alarming shift. ASCE found:

  • 85% of California water utilities rely on infrastructure components that have exceeded their design life
  • 105 billion gallons of treated water lost annually to leaking pipes
  • $11.5 billion needed in drinking water system upgrades over five years
  • Only $3.5 billion is currently planned — a $8 billion shortfall

This is not a drought problem. It is a pipes-and-pumps problem. Water systems built in the 1950s and 1960s are reaching end of life simultaneously. The cost of replacing them falls on local water agencies and their ratepayers, many of whom are already facing rate increases for other mandates (PFAS treatment, seismic upgrades, flood management).


Roads: D Grade, 30% in Poor Condition

California's road grade of D reflects a backlog of deferred maintenance that SB 1 (the 2017 gas tax increase) has only partially addressed. The state generates approximately $5.4 billion annually from SB 1 revenues, but the total maintenance and rehabilitation need is estimated at $60+ billion. At current funding levels, the backlog continues to grow.

Nearly 30% of California roads are in poor condition — significantly worse than the national average of 22%. Poor roads cost the average California driver an estimated $800-$1,000 per year in vehicle damage, increased fuel consumption, and lost time.


San Francisco: Aging Infrastructure Meets Wetter Future

A KQED investigation found that San Francisco's sewer and flood infrastructure lacks capacity for the extreme rainfall events that climate models project for the Bay Area. The city's combined sewer system — which handles both wastewater and stormwater in a single pipe network — was designed for 20th-century precipitation patterns.

As atmospheric rivers become more intense and frequent, the system is increasingly overwhelmed during peak storm events, resulting in untreated discharges to the Bay and localized flooding in low-lying neighborhoods.

The Investment Gap

ASCE's report card is not an opinion. It is an engineering assessment based on condition data, capacity analysis, and lifecycle cost modeling. The findings are consistent across cycles: California is spending less on infrastructure maintenance than the rate at which its infrastructure is deteriorating. The gap compounds annually.

For water systems specifically, the math is simple: $11.5 billion needed, $3.5 billion planned, $8 billion short. Someone pays — either through proactive investment now or through emergency repairs, service failures, and public health consequences later.
