Key takeaways

  • Parking chair belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Parking chair to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Parking chair from memory before moving on to harder problems.

Reference excerpt

A parking chair is a chair that is used by a motorist to informally mark a public parking space as reserved. Other objects are also used for this purpose, including trash cans, ladders, ironing boards, traffic cones, and similar-sized objects. In Boston, these are known as parking space savers or just space savers. For curbside parking spaces, two or more items are normally used; for angle spaces, only one is needed. The practice of using parking chairs is common in snowy weather within urban residential areas of the United States, where vehicle owners do not wish to risk losing their vehicle's previously occupied space in its absence. Other spaces may be hard to find due to accumulation of uncleared and plowed snow, and the owner of a vehicle may have invested considerable work in clearing a parking space to free the car. This is common in areas where side streets are fully lined with parallel parked cars allowing only the center of the street to be cleared of snow, which then has the effect of pushing the snow onto the parked cars. The practice is widely criticized because it reduces the amount of parking, and is considered unneighborly and selfish. This practice is especially common in the Northeastern United States (for example, in Boston and Pittsburgh), as well as Philadelphia, and the Upper Midwest and Great Lakes regions (for example, in Chicago, where it is referred to as "dibs"). In Pittsburgh and Chicago, the use of parking chairs is considered to be an "iconic" regional practice.

Use in inclement weather In snowstorms, vehicle owners with such a need mark the space as their own that their vehicle previously occupied after digging out the heavy snow that covered the vehicle and blocked them in. A such way to indicate that the parking spot is reserved is to place a lawn chair often referred as a "Parking Chair" to indicate others of the reserved spot for the owner that will soon return. The legality and level of enforcement of existing laws pertaining to this practice varies by location. Generally, curbside parking spaces are public property and are available to vehicles on a first-come, first-served basis. Still, respecting these makeshift markers has been accepted by citizens as a common courtesy during snowstorms.

While use is year-round, it is a particularly time-honored tradition in heavy snowfall accumulation, when a resident who "digs out" their spot on the street essentially declares ownership, which often goes unchallenged by neighbors for fear of retribution. The idea of the practice is that the person reserves the space from which they have freed their vehicle for future parking during the remainder of the storm and as long as snow remains on the ground. It is generally a Lockean recognition that the effort of the physical exertion of digging provides an entitlement to the space where the vehicle was previously located. But in some instances, spaces get reserved in this fashion even before a snowstorm starts.

Origin The practice is common throughout areas of the United States susceptible to large amounts of snow and where curbside parking on residential streets is the norm, especially in the Northeast. The items used have sometimes been referred to as the Pittsburgh Parking Chair, due to their common use in Pittsburgh and its nearby suburbs. Pittsburgh is a very hilly area, with houses very close together, and many older neighborhoods predate cars, having narrow streets with no driveways to park in and parking on only one side of the street. While such ad hoc parking restrictions have no legal standing in the city of Pittsburgh, common and long standing community tradition supports their use. As the "parking chair" is part of the culture of the city, local police generally turn a blind eye to these impromptu markers, which under legal jurisdiction, technically qualify as "abandoned furniture". Photographic evidence of the tradition has been found dating back at least to the 1950s. It is believed that the practice existed earlier, as the number of vehicles on residential streets has exceeded the number of available spaces. The origin of this practice may be outside the United States, as it is also a common practice in southern Italy, and with other objects in the United Kingdom.

Legality The practice has been outlawed in some places, including the city of Washington, D.C., where enforcement is strict and violators are ticketed. Some places specifically prohibit the practice, with levels of enforcement that vary. Sanctions against violators may include fines and confiscation of the markers. Other places either do not enforce or make legal allowances for this activity. In Baltimore, after the 2010 blizzards on February 5–6 and February 9–10, Mayor Stephanie Rawlings-Blake announced that the city would not enforce an existing ban on the practice. She said that it could not be stopped, saying that it was a local tradition and that it would be "like telling people they can't say 'Hon'". Some places, including Pittsburgh, do not place legal sanctions against those engaging in the practice, but make clear that anyone has the right to claim an informal space that was reserved by someone else for their own vehicle, regardless of courtesy. However, it is a general practice around the city to respect the markers of others. In 1994, Police in Dormont, a suburb of Pittsburgh, confiscated the markers from 200 spaces due to excessive complaints. Pittsburgh retailers sell novelty "Official Parking Chairs". In Boston, the law prohibits residents from saving the spaces they clear for longer than 48 hours from the moment a snow emergency is declared to be over. However, they are outright banned in certain neighborhoods of the city, such as the South End. In Aldan, Pennsylvania, the police chief confiscated all markers that were placed following the blizzards of 2010. He stated that he was enforcing a local ordinance in doing so. In Chicago, the "dibs" practice is illegal under §10-28-070. Though dibs incidents are traditionally unenforced in Chicago, there are notable police report rates for vandalism incidents involving saved parking spaces. On March 2, 2021, the Chicago Department of Streets and Sanitation (DSS) began removing "Dibs" objects along with household trash. WBEZ, Chicago's local NPR station, created a sign for residents to post that cites the Chicago statute prohibiting dibs.

Worked examples

Example 1 — a first encounter with Parking chair

Start with the simplest possible case. Write down what Parking chair claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Parking chair before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Parking chair ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Parking chair

In research
Parking chair appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Parking chair in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Parking chair is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chairs, Culture of Pittsburgh, Inclement weather management, so understanding it makes those chapters shorter.
In everyday life
Look for Parking chair outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
