A quiet but very important conversation has begun. Greenville County leaders have proposed exploring a planning concept known as development concurrency —a policy approach intended to ensure that infrastructure keeps pace with growth. At first glance, the idea sounds straightforward and even obvious: roads, water systems, sewer capacity, schools, and public services should be adequate before new development is approved. Few people would disagree with that principle.

But public policy is rarely as simple as its initial premise. The question facing Greenville—and increasingly the entire Upstate—is not whether growth should be managed. The real question is how it should be managed, and whether the tools chosen will protect the public interest without unintentionally creating new problems. Across the United States, regions that adopted growth-management tools with good intentions have sometimes produced outcomes no one expected: sharply rising housing costs, declining housing supply, increased barriers for small builders, and difficulty for families to find affordable homes.

The Upstate stands at an important moment. Population growth is accelerating, economic investment is increasing, and the Greenville–Spartanburg corridor is becoming one of the most dynamic regions in the Southeast. Decisions made now about how to manage growth will shape the region for decades. Greenville’s concurrency discussion is therefore not just a local technical issue. It is the opening chapter of a much larger question: How can the Upstate manage high growth rationally while preserving affordability, opportunity, and quality of life?

Understanding the Principle of Concurrency

In planning terminology, concurrency  means that infrastructure must be available at the same time development occurs. If roads, utilities, schools, or other public services are not sufficient to support a proposed development, the project may be delayed until improvements are built or funded.

In theory, the concept is attractive. It reflects a common-sense idea that growth should not outrun the systems that support it. Many communities have experienced the frustration of subdivisions appearing faster than roads can be widened, or new commercial centers arriving before utilities are expanded. Residents understandably ask why development should proceed when infrastructure is already strained.

Concurrency attempts to answer that question by linking development approvals to measurable infrastructure capacity. In practice, it can involve detailed standards such as road traffic thresholds, water and sewer availability, school capacity, emergency service response times, and other indicators of public readiness.

The goal is to ensure that growth occurs in balance with infrastructure , rather than forcing taxpayers to catch up later.

That objective is reasonable. In fact, most citizens would agree that infrastructure planning should be responsible and forward-looking. But concurrency, like many policy tools, can produce unintended effects depending on how it is designed and implemented.

Why Greenville Is Considering Concurrency

Greenville County’s interest in concurrency did not appear suddenly. It is the result of several long-term trends that are now converging.

First, the Upstate is experiencing sustained population growth . People continue moving to the region because of its strong economy, quality of life, moderate cost of living, and strategic location along the Interstate 85 corridor. Employers ranging from advanced manufacturers to logistics firms and technology companies have expanded operations across the region.

Second, that growth has placed visible pressure on infrastructure. Residents increasingly report traffic congestion on major corridors, concerns about road capacity, and questions about whether public utilities and schools can keep pace with new development.

Third, there is a growing expectation among citizens that local governments should demonstrate that they are planning responsibly for the future. Public officials understandably want to show that growth is being managed thoughtfully rather than simply reacting to events.

Concurrency appears to offer a structured way to address these concerns. By tying development approvals to infrastructure readiness, county leaders hope to prevent situations in which growth overwhelms roads, utilities, or public services.

The motivation behind the proposal is therefore understandable. Communities want growth that strengthens the region rather than diminishing quality of life.

Why the Idea Sounds So Reasonable

Policies like concurrency often gain early support because they align with basic ideas of fairness and responsibility.

Residents who already live in a community frequently ask why new development should be allowed if roads are already crowded or if public services appear stretched. From that perspective, requiring infrastructure to keep pace with development seems logical.

There is also a widely shared belief that growth should pay for growth . Many citizens worry that taxpayers end up subsidizing development through infrastructure expansions that follow new projects. A concurrency framework can appear to shift that burden toward developers or project sponsors rather than existing residents.

Another appealing feature is predictability. If infrastructure standards are clearly defined, developers may know in advance what conditions must be met for approval. In theory, this could create a more orderly process for planning growth.

These ideas are not inherently wrong. Responsible planning does require attention to infrastructure capacity and public investment. But policies designed around these principles must also consider the broader economic system in which development occurs.  The First Warning Signs The most important caution about concurrency is simple: the policy does not create infrastructure by itself.

Concurrency sets conditions under which development may occur, but it does not build roads, expand water plants, or construct schools. If infrastructure improvements take years to plan and finance—as they often do—development approvals may be delayed for long periods even when housing demand remains strong.

Those delays can have significant consequences.

When housing construction slows while population growth continues, the supply of available homes tightens. Builders face uncertainty about whether projects will be approved or postponed. Financing becomes more complicated, smaller developers may withdraw from the market, and projects that do move forward may shift toward higher-end housing in order to absorb rising costs.

The result can be an unintended chain reaction: reduced housing supply leads to higher prices, which make it harder for working families to remain in the community.

In other words, a policy intended to protect residents from the effects of growth can sometimes make the cost of living higher for those same residents if housing availability becomes constrained.

This possibility does not mean concurrency should never be considered. It means the policy must be examined carefully and designed with a full understanding of how housing markets and development economics operate.

Questions That Must Be Asked

Any discussion of concurrency or similar growth-management tools should begin with several fundamental questions.

Who ultimately pays for infrastructure improvements? If developers are required to fund upgrades, those costs may eventually appear in the price of homes or commercial space.

How will delays affect housing supply? Even temporary uncertainty in the approval process can discourage construction, particularly for smaller builders who cannot absorb extended timelines.

How will policies affect landowners? Families who have owned property for generations may depend on development opportunities to realize the value of their land. If approvals become uncertain or delayed indefinitely, those landowners may lose the ability to monetize assets they have maintained for decades.

How will small projects be treated compared to large ones? Complex regulatory systems often favor large developers with substantial financial resources while making it difficult for smaller builders to operate.

How will infrastructure improvements actually be funded and scheduled? Without a realistic plan for financing roads, utilities, and public services, concurrency may simply become a mechanism for postponing development rather than solving infrastructure problems.

These questions are not objections to planning. They are essential components of responsible planning.

The Broader Issue for the Upstate

Although Greenville County initiated the concurrency discussion, the implications extend far beyond one jurisdiction.

The Upstate region functions as a connected economic corridor stretching from Anderson through Greenville and Spartanburg and along Interstate 85 toward Charlotte and Atlanta. Decisions made in one county inevitably affect neighboring communities.

If one county restricts development significantly, housing demand may shift to surrounding counties. Infrastructure pressure can move across county lines. Regional employers depend on workers who can live within reasonable commuting distance of job centers.

For these reasons, the concurrency debate should be viewed as part of a broader regional conversation about how the Upstate intends to manage growth over the coming decades.

The region has many advantages: a strong manufacturing base, growing research institutions, a culture of entrepreneurship, and an attractive quality of life. Maintaining those strengths requires policies that support both infrastructure investment and continued opportunity for families and businesses.

A Moment for Careful

Thinking Growth management is one of the most challenging responsibilities local governments face. Communities want to preserve the qualities that make them desirable while also welcoming new residents, new businesses, and new opportunities.

History shows that well-intentioned policies can produce unexpected results when they are implemented without careful attention to housing supply, economic incentives, and long-term infrastructure planning.

The Greenville concurrency discussion therefore deserves thoughtful examination rather than quick approval or quick dismissal. The principle behind the idea is understandable. But the Upstate must ensure that any approach adopted truly improves the balance between growth and infrastructure without creating new barriers to affordability or opportunity.

The conversation that has begun in Greenville offers a valuable opportunity for the entire region to consider what rational growth management should look like in the decades ahead.

Looking Ahead

The next article in this series will examine a cautionary case from outside the region. California’s housing crisis is often discussed in political debates, but the real lesson is more complex than simple slogans. Over time, a combination of housing supply constraints, regulatory delays, and planning fragmentation contributed to dramatic increases in housing costs and rising homelessness.

Understanding what went wrong in California is essential for regions like the Upstate that are now experiencing rapid growth. By studying those mistakes carefully, communities can recognize early warning signs and design policies that protect both infrastructure and housing affordability.

The goal of this series is not to oppose growth or to advocate unrestricted development. The goal is to explore a rational approach to managing high growth—one that preserves opportunity, respects property rights, supports family affordability, and keeps infrastructure aligned with the future of the Upstate. Greenville’s concurrency debate is simply the place where that larger conversation begins.
