California's infrastructure is aging, underfunded, and falling behind. Grand juries across 52 counties have produced 1,629 infrastructure findings and 3,533 recommendations from 954 reports. An additional 2,315 findings address water and sewer systems, and 1,369 findings document road and bridge conditions. Together, they reveal a state where deferred maintenance has become the default.

The Deferred Maintenance Crisis

Infrastructure findings have grown steadily as California's built environment ages. 232 findings specifically cite deferred maintenance or aging infrastructure as a concern.

The post-2008 economic collapse created a structural break: counties deferred maintenance during the recession and have never caught up. The result is a growing backlog that becomes more expensive to address with each passing year.

What Grand Juries Are Finding

The 1,629 infrastructure findings reveal consistent themes across 52 counties:

  • Deferred maintenance compounding: 232 findings document how deferring routine maintenance accelerates deterioration and multiplies eventual repair costs. A $10,000 fix becomes a $100,000 replacement when deferred a decade.
  • Revenue-need mismatch: Flat property tax revenues and declining gas tax receipts cannot keep pace with the cost of maintaining aging systems. Infrastructure designed for the 1960s-1970s population is serving a state that has more than doubled.
  • No capital planning: Many agencies lack long-term capital improvement plans, responding to failures reactively rather than maintaining proactively.
  • Climate adaptation lag: Sea level rise, drought, and extreme heat are creating new infrastructure demands that existing systems were not designed for, and adaptation projects take a decade or more to plan and build.
  • Outdated records: Some agencies lack current maps or inventories of their own infrastructure, making damage assessment and maintenance planning impossible.
The aging infrastructure, design limitations, and deferred maintenance of the facilities contribute to safety concerns for both correctional staff and incarcerated persons (IPs).
Airport hangars and other infrastructure at the smaller airports are in disrepair due to longterm deferred maintenance. Delaying repairs accelerates damage and can significantly increase the final cost of repair, as well as foster dissatisfaction among hangar tenants.
Flat revenue and growing major expenses, including water meter installation and aging infrastructure replacement, threaten FCWD’s financial viability.
The $6.85 million principal balance in Federal Bureau of Reclamation Small Project Act loans remains a burden to the RVCWD, limiting access to available funding sources for infrastructure, maintenance, and upgrades.
There is no county-level agency chartered to plan, propose, or build regional district-spanning drought-resilience infrastructure.
Damage to water lines by the local utility company while undergrounding electrical lines could have been minimized if an upto-date subdivision parcel map of the water infrastructure existed.

Water & Sewer Systems

2,315 findings address water systems, sewer infrastructure, and wastewater treatment. These are among the most consequential infrastructure findings because they directly affect public health:

  • Water quality failures: Small water districts serving rural communities cannot meet state drinking water standards, exposing residents to contamination risk
  • Aging pipes: Water and sewer mains installed in the mid-20th century are reaching or exceeding their design life, leading to breaks, leaks, and infiltration
  • Grant dependency: Smaller systems can only fund upgrades through competitive grants, creating a cycle of deferred maintenance punctuated by occasional windfalls
  • Governance transitions: Deferred maintenance in small districts sometimes forces absorption by larger providers, eliminating local control
The Dos Palos water system does not consistently meet state water quality standards which can cause health issues if consumed over a long period of time.
San Juan Capistrano’s deferred maintenance of the water/wastewater utility resulted in the need to transition the facility to a larger water provider to allow more efficient management and maintenance of the infrastructure.
Should the City not receive the $7,000,000 grant to upgrade the sewer system, the residents will continue to have sewage issues.

Roads & Bridges

1,369 findings document road conditions, bridge safety, and transportation infrastructure maintenance:

  • Pavement condition: Counties with PCI (Pavement Condition Index) scores below 40 face roads so degraded that rehabilitation costs far exceed what routine maintenance would have required
  • Reactive maintenance: Some agencies spend 85% of their road maintenance budget on reactive repairs (potholes, emergency fixes) and only 15% on preventive maintenance, guaranteeing continued deterioration
  • Equity gaps: Road quality varies dramatically between districts within the same county, creating unequal service for taxpayers paying the same rates
The City of Oakland needed to repair over 53,000 potholes or similar pavement failures in the most recent 2023-2024 Fiscal Year.
The County road maintenance strategy differs by Supervisorial District leading to inconsistent road repair expectations among districts. This lack of a coordinated strategy leaves residents frustrated and with a sense of unfair treatment.
The Grand Jury found that 85% of maintenance work is reactive, and 15% proactive. This ratio leads to potholes developing sooner.

What Grand Juries Recommend

The 3,533 infrastructure recommendations focus on planning, funding, and accountability:

  • Capital improvement plans: Develop and maintain long-term infrastructure plans with prioritized projects, cost estimates, and funding sources
  • Deferred maintenance funding: Establish dedicated funds for deferred maintenance, not dependent on general fund surpluses
  • Performance metrics: Track and publicly report infrastructure condition scores, response times, and repair backlogs
  • Asset management: Create and maintain current inventories and maps of all infrastructure assets
  • Right-sizing: When full replacement is unaffordable, consider downsizing project scope to match available funding
The Amador County Board of Supervisors oversee the development of a short-term action plan, to be developed by the Public Works Director, to improve the County's roads that incorporates current road conditions, prioritizes road projects, includes a forecasted schedule of road work, to be updated at least semi-annually. To be completed by November 1, 2025.
Establish goals and performance metrics which measure the efforts of the Department of Transportation and report them to the Board of Supervisors quarterly to track the effectiveness of complaint-driven road repairs by July 31, 2025.
A maintenance and budget plan for the ongoing operation of the soon to be installed GAC filtration system should be developed by the City of Fowler’s Public Works Director by March 31, 2026.

Then and Now: A Familiar Pattern

Infrastructure concerns are among the oldest in the grand jury record. Early findings show the same themes that dominate today:

While construction delays in highway 76 continued, many housing developments using this highway were built without the transportation infrastructure to support them.
The City claims that “growth will pay its way” yet it plans to reimburse a developer for installing infrastructure improvements using 40% of the sales tax revenues from a store in the development. (cid:121) The City entered into a development agreement with Browman Development Company for the Browman Development (Crossroads Community Specific Plan), Agreement No. 02-2003. The Council approved t...

San Diego's 2007 finding about housing developments built without supporting transportation infrastructure remains one of the most consequential patterns in California governance: growth generates revenue but creates infrastructure obligations that outlast the political tenure of those who approved it.

State Oversight Context

California's state-level oversight bodies — catalogued at caoversight.org — have also examined this topic. The 19 reports below, from Local Agency Formation Commission, Legislative Analyst's Office, Little Hoover Commission, and State Controller's Office, provide the broader policy context within which county grand juries operate.

Methodology

This report analyzes 1,629 findings and 3,533 recommendations from 954 reports across 52 counties. Findings were identified by matching on "infrastructure." Water/sewer findings (2,315) matched on water system, water district, wastewater, or sewer. Road findings (1,369) matched on road+maintenance, bridge, or pothole.

All data is sourced from publicly available grand jury final reports. Quotes were editorially curated for specificity and county diversity.
