The word "plan" is fairly common in the English language. If you ask someone about their plans for the weekend, for instance, you can expect an answer in reply—even if the person you asked hadn't planned a response.

A different kind of planning, frequently discussed in the news and government, is a lot harder to describe. You've probably heard some or all of these terms used before: urban planning, community planning, city planning, regional planning There are also climate action plans, capital investment plans, transportation plans, and strategic plans. There are so many kinds of planning, it can be hard to tell them apart. It gets even more confusing when engineers, architects, or politicians, not planners, are making some of these plans!

It's ok if your understanding of planning drops off somewhere between weekend plans and urban plans. Planetizen Courses is here to help.

What is Urban Planning?

There is a specific professional field known as planning. You can get a degree in planning, and then get hired to a job as a planner. Planners can get professionally certified and earn a graduate degree in planning. Professional planners spend their days writing and implementing plans.

So let’s say one of the definitions of planning is that it’s the work done by planners, but that’s obviously a bit too...simplistic. All of these varieties of planning have one thing in common: preparing for the future. Other professions do it too, but preparing for the future is the primary motivation of urban planners.

How will people get around in the future? Where will people live and work in the future? How will all of the systems required to support those people—electrical grids, sewers, and the water supply—fit into the city? These are all questions that planners are working to answer, using tools and policies specific to the field of urban planning.  The numerous considerations raised by those questions again reintroduce the possibility of architects, engineers, and politicians doing some of the planning. So where does urban planning fit into the mix with all this planning?

Why is Urban Planning Important?

The complexity of planning for the future creates a need for an intermediary between different communities and related professional fields, and their fundamental intersectionality is one way urban planners distinguish themselves for other professions. You'll often hear planners say that they are "professional generalists" or they "wear many hats." Planners are like a Swiss Army Knife in the city building process, which is another reason planners are sometimes confused with engineers, architects, or politicians.

The next step in the planning process is synthesizing all that information and communicating a vision of the future for approval by a governing body--like a city council or a county board of supervisors. The approval process can be intensely political, so planning is also fundamentally political.

In many cities, planners will also manage the implementation of that approved vision by enforcing the legal tools of planning, otherwise known as zoning codes. There is a clear distinction between the process of planning for a city's future and the process of implementing the vision, but planners will be involved in both to ensure the city evolves as planned.

Urban Planning History

Another way to understand planning is by studying the way the field has changed throughout history, and how that evolution in reflected in the world of today.

A few men from history had the opportunity to plan cities from scratch, like Pierre Charles L'Enfant in Washington, D.C., Daniel Burnham in Chicago, or Georges-Eugène Haussmann in Paris. Other very powerful men from the 20th century (yes, in the past it was mostly men doing the planning), like Robert Moses and Le Corbusier, transformed entire neighborhoods and cities to fit their preferred model.

After zoning codes gained popularity in the early 20th century, planners began to focus almost entirely on land use, and planning began to mean the process of deciding where to locate residential, office, retail, and industrial uses in new and existing cities. The desire to separate residential uses from noxious industrial uses, enabled by the mass production of the automobile, represents a significant step toward creating the mostly suburban and sprawling country we live in today.

In the 21st century, planning is more grassroots in orientation, inspired by the writings of Jane Jacobs, among others, and enshrined in legal and political tools designed to protect the interests and values of local residents and businesses. The term urban planning, rather than city planning, has become more popular as the public has taken a renewed interest in cities and as the environmental and economic consequences of the 20th century model of planning have become apparent.

Urban Planning Today

To this day, numerous debates contest the future of planning, and planning continues to evolve as a result. Big questions will determine the kinds of values embedded in contemporary plans—like how to address climate change and housing affordability; how to overcome a long history of racist and discriminatory regulatory practices; and how much planners should regulate the form of buildings, not just the use of land.

The answers to those questions will shape the world of the mid- and long-term future.

So what are your plans?
