News Why Deferred Maintenance Costs More Than Communities Think

Deferred Maintenance Is More Than a Backlog

Deferred maintenance is often described as a backlog problem. The road needs repair. A pipe replacement is pushed to the future. A facility improvement is delayed due to limited funding. Over time, those delayed projects accumulate into a growing list of needs that can become increasingly difficult for communities to manage.

But deferred maintenance is more than a backlog. It is also a timing problem. When communities delay infrastructure investment, they are not simply moving a project to a future year. They may be allowing an asset to move further along its lifecycle, where lower-cost treatment options become less effective or disappear entirely.

WithersRavenel’s Keith Pugh, PE, and Craig Roach help public works leaders communicate these realities to elected officials and decision-makers. Their work focuses on translating engineering and financial data into conversations that help communities understand service levels, funding needs, risk, and long-term value.

The Seen and Unseen Work of Public Works

National Public Works Week’s theme, “Rooted in Service, Powered by Community,” is a reminder that some of the most important public works contributions are not always visible. A new road, bridge, sidewalk, or public facility may be easy to recognize as an investment in the community. Maintenance work can be harder to see, especially when it involves underground utilities, stormwater systems, pavement preservation, or routine asset renewal.

That does not make it less important. In many cases, the unseen work is what keeps the visible parts of a community functioning. Deferred maintenance becomes costly because it delays the service-oriented work that protects infrastructure before failure occurs.

Why Waiting Has Consequences

“Deferred maintenance is usually described as a backlog problem,” Roach said. “But we’ve found it’s more useful to describe it as a decision-timing problem. Because what’s really happening is that decisions are being made later than the asset lifecycle allows.”

When funding is limited, delaying a project can feel like a practical decision. Communities are often managing multiple urgent priorities, and not every need can be funded immediately. A project that is not creating an obvious service disruption may be easier to push into a future budget cycle, especially when other needs feel more visible or more immediate.

The challenge is that infrastructure continues to age, whether funding is available or not. A pavement segment, utility line, stormwater asset, or public facility may still function today, but its condition may be declining in ways that are not yet visible to the public. By the time the problem becomes obvious, the lowest-cost treatment options may already be gone.

Costs Do Not Rise Gradually

One of the central lessons of lifecycle planning is that waiting has consequences. A small preventive maintenance project can become a larger rehabilitation effort. A rehabilitation project can eventually become a full reconstruction. As conditions decline, the community loses flexibility and may have fewer opportunities to choose a lower-cost, lower-disruption solution.

One of the most important ideas in lifecycle modeling is that infrastructure costs do not always rise gradually. They can accelerate. Early in an asset’s life, preventive maintenance may extend service life at a relatively low cost. As the assets continue to deteriorate, more intensive rehabilitation may be needed. If action is delayed too long, reconstruction may become the only viable option.

Roach summarized the pattern clearly: “First, costs don’t rise gradually. They accelerate. A small preventive treatment becomes a rehab. A rehab becomes reconstruction.”

The Maintenance Work People Do Not Always See

Keith often frames this in terms of what communities choose to preserve. New infrastructure naturally gets attention, but maintenance is what protects the investment over time.

“Nobody cuts a ribbon for a sewer manhole rehabilitation. But it’s exactly those maintenance activities that improve our overall infrastructure score,” Keith said.

This is why infrastructure asset management can be so valuable during budget conversations. It helps leadership see that lower-cost maintenance today may reduce the need for higher-cost reconstruction later. Instead of treating preservation funding as optional, lifecycle planning helps show how early investment can protect long-term value and reduce future pressure on capital budgets.

For communities across the Southeast, where growth, aging infrastructure and funding competition often intersect, this kind of planning can be especially important. Public works leaders are not only maintaining existing systems. They are also preparing those systems to support future residents, businesses, and public services.

Deferral Eliminates Options

Cost is only one part of the issue. Deferred maintenance also limits choice. When an asset is still in fair or manageable condition, communities may have several options available. Preventive treatments, targeted repairs, or phased improvements may be enough to preserve performance and manage risk. As the condition declines, those options begin to disappear.

At a certain point, preventive maintenance is no longer effective. The community may have to choose between major rehabilitation and replacement. If deterioration continues, even rehabilitation may no longer be practical.

“Second, deferral eliminates options,” Roach said. “Early in the lifecycle, you have multiple treatment choices. But as the condition declines, those preventive options disappear.”

Failure Forces the Most Expensive Decision

For public works teams, this can make future decisions harder to explain. Leadership may ask why a project is suddenly so expensive when the real issue is that earlier, lower-cost opportunities were missed. Residents may see only the final reconstruction project, not the years of deferred decisions that narrowed the community’s options.

The most difficult infrastructure decisions often come when failure is imminent or already occurring. At that point, there may be little room for strategy. The community must respond to the emergency, service disruption, or public safety concern in front of it. That is when infrastructure management becomes reactive, and when the most expensive decision is often the only decision left.

“By the time deterioration is obvious enough to demand action,” Roach noted, “often the only thing left is reconstruction.”

Moving From Reactive Repair to Proactive Planning

Lifecycle planning helps communities avoid reaching the point where failure dictates the decision. It allows public works leaders to show what happens when action is taken early compared to what happens when investment is deferred. That visibility can help change the conversation from, “Why is this so expensive?” to, “Here is what happens if we wait.”

Deferred maintenance will always be part of public works planning. No community has unlimited funding, and difficult choices are unavoidable. But lifecycle planning can help communities make those choices with better information. It can show the likely consequences of delaying a project, compare the cost of preservation against the cost of reconstruction, and help leadership understand which investments protect long-term value.

Most importantly, lifecycle planning can make the tradeoffs visible before the decision is made. Public works leaders should not have to explain the cost of failure only after failure occurs. Lifecycle planning gives them a way to communicate the impact of funding decisions earlier, when there are still options available.
