Fads: Karts and Tumbling Centers

Proud is the city — she finds a place for many a fad today,
But she's more than blind if she fails to find a place for the boys to play.

—Denis Aloysius McCarthy
Give Them a Place to Play

In good times and in bad, Americans have an affinity for fads. The list of twentieth century attractions and distractions includes mah-jongg, bridge, and canasta, hula hoops, hot rods, and rock and roll, "Knock Knock," miniature golf, Scrabble, bowling, and many, many others. To a varying degree, each interested people, stimulated them, and provided a means of self-expression or a way to pass the hours.

This report looks at two activities which concern planning agencies: karting and rebound tumbling. These two are selected first of all because they are current fads. Secondly, inquiries from planning agencies to ASPO Planning Advisory Service indicate that municipal officials are asking planners for facts and advice about them.

This report begins with two premises: 1) that current fads, in particular those involving land use, are valuable to analyze in order to be better prepared for others that inevitably will follow; and 2) that we have had enough experience with fads to be able to deal with new ones when they present questions requiring public policy decisions.

These premises are not advanced without restraint. It must be recognized that each fad is inherently unique. A fad must be new if it is to make the grade with the American public. The qualities that attract us to it also tend to separate it from other fads which have gone before it. There has been a notable lack of success among imitators of the really popular fads.

They follow no particular pattern. Some appear, blossom, expand rapidly, and die just as quickly. A recent case in point is the hula hoop. Few households were not affected. However, it flourished for only two summers.

It is extremely difficult to tell whether a fad will fade or will linger on to become a part of the American scene. Among the more durable activities that started out as fads are miniature golf courses and driving ranges, now nowhere near their popularity peak, but still doing well commercially. Thus, one writes of fads with some trepidation; you cannot tell exactly where you are in the cycle — whether the zenith is in the past or lies in the future, whether the craze will disappear or linger on.

Another element leading to restraint is the irregular distribution of popularity. Inhabitants of some places pick up the new with ease — California, particularly, seems to be open country. But people in other places seem unable to embrace anything that time has not tested. Several cities, for example, have outlawed karts, while at least one (Hope, Arkansas) has permitted a track to be built in a public park. Between these extremes are many possible responses.

Finally, the birth, growth, and span of any fad is likely to be influenced by many other factors: state laws, authority of local officials to act, economic conditions that favor or oppose the growth of the fad, and the applicability of laws in existence at the time the new and unique situations are introduced.

Recognizing these limitations, we nevertheless can set forth some general aspects of fads in relation to planning. While there are risks in trying to predict what will happen in any given community as a fad spreads, failure to meet the situation soon enough can be costly — oftentimes a decision to do nothing (in the hope the fad will soon evaporate) proves dangerous.

Of course, the majority of fads will never affect planners. Medical men may be alarmed by the physical damage they may cause, psychologists may interpret them as outlets for individual and group drives, economists may see in them new evidence of affluence, and oratorical clergymen may cite a particular fad as evidence of spiritual decay. But, the planning official is concerned with fads principally as they affect the character of land use. He is concerned also with safety, insofar as it is a matter of public concern. And, he is involved when the fad has a propensity to attract large numbers of participants and spectators — and their automobiles.

It is impossible to cover all eventualities or the infinite variety of circumstances in which fads will operate. Yet, even though the approach may be a general one, it can provide meaningful orientation for the planner suddenly asked for counsel. This is the hopeful goal of this report.

Karts and Karting

A kart1 is a low-slung vehicle made up of four small wheels, a metal frame, a gasoline engine, a seat, a steering mechanism, and control pedals. The engine is about equal in power to that used in a large lawn mower. Professionals in the sport of karting have been clocked at speeds of more than 50 miles per hour.

Karting, like so many of our leisure activities, is California born and bred. The first kart, historians of the sport say, was built in the summer of 1957. Since then, the fad has grown rapidly considering the fact that a kart is not a 98-cent item. It is popular in most parts of the country, although the majority of karting clubs appear to be concentrated at present in the warm weather areas of the west coast and Gulf states.

One indication of this growth can be found in mail order catalogues. All of the large houses featured karts in their spring editions ranging from as little as $75 in kit form to $200-plus, fully assembled. The amount of this catalogue space is three times what it was just a year ago.

The following description which appeared in the spring, 1960, issue of the Montgomery Ward general catalogue presents a succinct summary of what planners may face:

Every member of the family will get a kick out of riding this junior-size auto. It's the ideal way of teaching youngsters correct driving principles. Karting tracks are springing up throughout the country — if your community does not have one, organize your own club. Karts are not intended for street use — but any hard surface 25- x 100-ft. area can be set aside for a track for driving, races, time trials, etc.

This description of karting and its potential course of development should send planning officials scurrying to determine whether their zoning and other laws could deal with kart tracks. Note particularly that there is an emphasis on the small amount of ground needed, a characteristic that makes karting similar to the miniature golf craze of 1930's.

The assertion that "karting tracks are springing up throughout the country," is generally true. New Jersey is an exception; the stringent requirements of its automobile race track law have been held applicable to karting tracks, and even the karters have placed the state out-of-bounds.

Among the other indicators of karting's expansion are:

At least two magazines are devoted exclusively to karting. The most recent publisher's statements to the Post Office department, claimed paid circulation in excess of 60,000 each. Many automotive and hobby magazines also have featured articles on the sport in recent months.

A survey reported at least two dozen permanent tracks were operating by local kart clubs last fall and summer. The survey did not claim to be comprehensive.

There are three associations active in the field. These represent various combinations of manufacturers, operators of commercial karting tracks, and kart owners and clubs.

Reasons for Popularity

Why is karting popular? What are its features that attract a following?

While the individual's investment in a kart may range beyond $200, a relatively low outlay is needed for the track itself. Airports, sections of automobile racing tracks, and similar places now are sites for karting tracks. Industrial and supermarket parking lots have been used. While it is unlikely that the 25 x 100-foot minimum listed in the advertisement above would be satisfactory to the true karting club for very long, there is a low level of demand for overall space. Problems such as those involved in finding a site to which karts can be carried conveniently, where the noise is not likely to bring down the wrath of the community, and where there is sufficient space for spectators are the barriers to the growth of karting.

A "togetherness" aura permeates the literature on karting. It assertedly is an activity in which father and son — indeed, the whole family — can engage in together. The family is encouraged to take an outing to the track on a Sunday afternoon. Some tracks sponsor "family days" on which higher powered karts are banned. Not the least controversial aspect of this argument is the assertion that karting presents the father with an opportunity to inculcate good driving habits in his offspring. This argument has been decried by one jurist who has been quoted as saying, "To put a five year old baby in a racing car does violence to the child's nature. I'll see these kids in court before they are old enough to get a driver's license." Nevertheless, it is apparent that the fledgling kart industry, plus magazine promotion, has done much to advance the image of karting as an activity for all but the smallest of children.

The opportunity for tinkering with a machine is present. There is something in karting that captures the zest of do-it-yourself that is present to some degree in hot-rodding and dragging with little of the disapproval sometimes associated with them. The practitioner can utilize his energies and mechanical talent adjusting and testing carburetors, attempting to coax a little more speed or mileage. Whether you start with a kit or a preassembled kart, the prestige in the karting fraternity is likely to come to those who have done the most successful tinkering.

There is an opportunity for competition among the kart c1ubbers. The sport also attracts those who seek an opportunity to test their driving and mechanical skills in competition. The associations sanction meets among young people only when the speeds are governed. But undoubtedly, one of the thrills that sustains karting is the opportunity to try to get somewhere faster than some­one else.

Pattern of Growth

Because karting appears to be still in the early stages of development, an attempt to predict the future lines of growth or the intensity of its vigor is not without risk. At present, there are two general trends.

In some places, kart tracks have been set up on a commercial basis. Persons walk in, pay a charge, and drive around for a stated number of laps. This activity does not differ from tumbling center operations. It is a business, pure and simple. In fact, it appears that some trampoline centers are opening kart tracks as a sideline, perhaps in the hope that karting will pick up any slack caused by a drop in public interest in "bouncing." In any case, the expansion is a logical one from a business standpoint. Although it must be noted that the character of the karting business is substantially different from that of the trampoline business, both can be characterized as "amusements." Tumbling centers and commercial karting tracks of this type are similar, too, in that they require little land, and a relatively low investment that can be recovered quickly, thus reducing the economic risk on what well may turn out to be a temporary fad. These circumstances have combined to place commercial karting and similar businesses in places such as shopping centers and fringe commercial areas along highways where they can attract the motoring trade.

The other development trend is the kart club track. Participants sponsor and arrange races and other competitive activities for their members and visiting karters. They attempt to find a track site. They function in such important areas as policing the sport and obtaining insurance.

The requirements for a track are not substantial. A solid dirt track, a few bales of hay at strategic points, a pit area — this is the minimum. Some of the highly organized clubs have been able to secure sites that lend themselves to full development as tracks, places such as old airports. Some tracks have been paved; the cost of paving is small because the loads are light. Tracks range from as little as a quarter-mile to as much as a half-mile, but even these distances can be squeezed into small acreage; putting a large number of turns into the layout is encouraged.

There has been some tendency for young organizations to secure places such as parking lots at shopping centers and vacant land in semi-built up areas for part time use. However, objections from neighbors eventually lead to permanent sites in outlying areas.

The future of the sport, in long range terms appears to rest on its ability to build interest through clubs sufficiently large and well-directed to: 1) obtain tracks and 2) police participants so that problems, especially safety problems, can be kept within bounds. The fact that the individual karter must make an outlay of money and time would seem to encourage this condition; if he buys a kart he wants to be able to use it. Commercial karting tracks are not likely to sustain the manufacturing end of the industry forever. Club activity, on the other hand, with its relatively high personal commitment, can possibly carry the fad for some years to come.


The question of whether to attempt prohibition of karting within the municipal or county boundaries, as with all new land uses, depends in part upon community acceptance of the new activity. Karts may be objectionable in a built up area near residential zones. In a city with plenty of open space and with sufficient buffers between kart tracks and homes, there may be few frictions. The point is that the initial response need not necessarily be prohibition, which so often proved unsuccessful in the treatment of hot rods. (See ASPO Planning Advisory Service Report No. 74, Hot Rods, Car Clubs and Drag Strips, May 1955.)

Yet, it must be observed that many municipalities would have the authority, were their officials so inclined, to completely exclude kart tracks. Where it has power to do so, a local government could probably kill off a fledgling kart group by requiring extremely rigorous track specifications such as those in New Jersey.

At least one municipal zoning ordinance in California bans all tracks other than those used exclusively for racing. This ban has been upheld in an appellate court test. Commercial tracks prohibit racing, in many cases, in order to qualify for insurance coverage at reasonable rates.

From the overall view, direct prohibition in built up areas may result in pushing kart clubs and commercial tracks into the urban fringe areas, thus delaying the time to meet the problem. Worse still, a karting track in an area ripe for development may help substantially to set the character of growth. Should karting become established as an accepted activity, planning agencies will be faced with a case in which no area wants an activity for which there is a pronounced public demand. This locational problem is similar to the case of automobile graveyards and garbage dumps — both "undesirable" uses — but for which some provisions must be made.

Regulatory problems involved in karting have arisen in three forms: safety, noise control, and land use control.

Safety. This aspect of karting has caused considerable public controversy. It appears to be the battleground on which karters and anti-karters will come to grips. The National Safety Council has come out strongly against both racing and the driving of karts by underage persons. In a policy statement adopted by its Traffic Conference in March 1960, the NSC says:

The National Safety Council opposes the use of miniature motor vehicles, commonly called carts, go-carts, by drivers below driver licensing age.

While the laws of all states exclude these miniature vehicles, designed primarily for use by children, from the public streets and highways, there is little control over their use on private property. As a result, children have been killed or injured operating these vehicles, sometimes in speed events sponsored by adults. Motor vehicle speed events of any type are opposed by the National Safety Council.

The Council therefore urges parents, dealers in these vehicles, and organizations to refrain from sponsoring or conducting competitive events using miniature motorized vehicles, and to do all possible to see to it that they are at no time operated by persons under legal driver age.

A representative of the American Kart Manufacturer's Association has responded:

Three karting fatalities during 1959 have been highlighted yet neither the athletic goods or bicycle industries are scored as being responsible for hundreds and hundreds of injuries and fatalities despite decades of experience. Juvenile accident data fills many dreadful pages; the source of the problem can only be Delinquent Adults. . . . In attempting to determine the breadth and depth of NSC aid to automotive safety, we are reminded of the admirable hot rod movement with club standards of discipline and technical knowledge that may well exceed those of the homes and schools of attendees. We believe the NSC can claim no credit here, in fact opposing forces are believed to exist. The question then arises if the complexities of automotive safety can be solved by comprehensive research or by poster-pasting, finger-pointing, and Monday-morning-quarterbacking.2

It should be emphasized that there is universal agreement on one aspect of karting. That is, karts do not belong on the streets. These vehicles are so close to the ground that they are difficult to see when approaching head on, impossible to see when they pull up behind or beside a car or truck going in the same direction. Karts cannot be registered as motor vehicles in any state, and several state attorney-generals have made specific rulings to the effect that police may order their removal from the streets.

Undoubtedly, karting safety is controversial because of the fact that children of tender age can be and have been involved. This introduces some different regulatory considerations. The principle is accepted that laws for juveniles can be different in character and objective than for adults. Special municipal legislation imposing juvenile curfews is an example.

Then, too, local government's exercise of the police power can be aimed at promoting the safety of the public at large. Local laws have applied tests of safety in the cases of businesses catering to the general public.

These are essentially legal matters. Hence, the advice of the municipal attorney should be sought as to the permitted extent of authority to impose safety standards to this kind of activity. The specific measures which might be drawn are subject to state laws.

Thus, among the responses that a local government might make on a question of karting safety include: 1) prohibition, 2) special legislation covering juveniles, and 3) legislation covering matters such as safe separation of spectators from the track, handling and storage of fuels, minimum insurance coverage, mandatory safety equipment for the track, the karts and drivers, and so on. Racing may be banned at commercial tracks. (See Appendices A, B, and C.)

Noise Control. The editors of one karting magazine observe:

Throughout the country the biggest single public complaint against karting is that it makes so much noise. This factor, more than anything else, has driven karters out of built up areas, forcing them to relocate in remote, often inaccessible locations, frequently making it impossible to run at all. The pity of the thing is that all this is our own fault.

The argument against mufflers — that they lower the engine's power output — is a valid one, but it is certainly better to run with slightly less power than not to run at all. At the present time we know of no adequate muffler for kart engines. The company which introduces such an accessory should be sure of a wide market.3

The karters' difficulties with noise control have evidently brought municipal anti-nuisance ordinances into play. Clearly, excessive noise can be a basis for complaint by distressed neighbors. It should be noted that there is usually some reluctance on the part of people to bring complaints; many police departments prefer not to act on their own initiative in this kind of situation. However, it appears that most kart clubs have given way when faced with substantial hostility from nearby residents or property owners when the latter have the law on their side.

The responses that a municipality may have here, then, are not necessarily based upon a choice between prohibition and sanction. Rather, the matter of noise control (apart from its relation to zoning which will be discussed later) is one of accommodation. For example, one city has limited commercial operations from 8 A.M. to 10 P.M. on weekdays, and from noon to 10 P.M. on Sundays. (See Appendix A for the conditions imposed by one planning agency on commercial tracks .)

Zoning. As "close neighbors," kart tracks are considered undesirable; as "distant friends" to visit, however, they are more and more in demand. Even the ardent karting enthusiast would frown on living across the street from a kart track — noise, traffic, and the negative effect on property values are the chief deterrents.

Determining the proper location of the go-cart site is a growing concern of the planner and zoning official. As the fad increases in popularity, some communities are faced with not one, but several karting establishments. In the absence of specific locational provisions in the zoning ordinance, karting tracks have been built in a variety of places, among them parking lots, amusement and public parks, rural highway intersections, residential areas, and industrial zones. With proper site treatment, the kart track can function well in some of these areas; however, they are clearly inappropriate, for others.

Some clues to the proper treatment of karting sites can be determined from the way analogous uses are zoned. Race tracks and drag strips share common features with karting tracks. All make noise, create safety problems, require parking facilities, and generate traffic. Usually race tracks and drag strips are zoned into least restricted commercial and industrial districts; in some instances specific conditions must be sent before a permit is granted.

Another parallel use is the drive-in-theatre, an amusement facility generating considerable traffic and creating a potential nuisance from noise and lights. One technique, used in a number of recent ordinances, is to treat the drive-in theatre as a special use subject to special requirements. The Kansas City, Missouri, zoning ordinance (1951) has provisions for drive-in-theatres that indirectly relate to kart sites.

1. A minimum land acreage figure is established.

2. Through siting arrangements, traffic congestion is kept to a minimum.

3. Lights used to illuminate the site are so arranged as to reflect light away from adjoining property and streets.

4. Parking space is provided in relation to the vehicular capacity of the theatre.

5. Theatre property is a certain distance from the boundary of a residential district.

Various principles for regulation of kart sites can be established.

Traffic. Providing access to major streets or highways will reduce traffic congestion in surrounding areas. Moreover, proper ingress and egress between the highway and spectator area should be provided.

Parking. The karting race track with spectator bleachers or grandstands requires off-site parking facilities. A standard of one parking space per three seats would be appropriate.

Noise. Noise control can be accomplished in either of two ways. Karts can be muffled, a technical problem the karting manufacturers have not as yet solved; or the karting site can be regulated to reduce noise interference to neighboring properties. In the latter solution the following techniques are applicable: restrict karting tracks to outlying, undeveloped areas; establish minimum distances between the track and nearby properties; fix hours of operation to reduce the nuisance effect; modulate or prohibit public address systems.

Safety. Pavement on the karting track should be smooth and in good condition to offer maximum safety to participants and spectators. Bulk storage of fuels and lubricants should be outside the go-cart roadway area.

The community which faces a go-cart invasion has several zoning alternatives. If it believes that karting is a fad, doomed to extinction in a few years, it may wish to issue temporary permits, renewable every few years and subject to stiff license fees. Considering the possibility that the fad may become permanent however, the community will eventually have to amend the zoning ordinance.

If it assumes that go-carts require special use treatment, appropriate and specific standards should be set up to guide the zoning board of adjustment or the zoning administrator. Considerations of traffic, parking, noise, and safety are essential.

Perhaps the easiest approach is to restrict karting tracks to least restricted commercial or industrial zones, with few conditions attached. In this way, the community decides that go-carts are nuisance uses and treats them accordingly.

Tumbling Centers

Trampolines4 for many years were confined to gymnasiums. Rebound tumbling equipment was considered something for skilled athletes. Now, however, the sport is somewhat "old hat." After making a "public" appearance several years ago, it seemed to reach a high point. Recently, however, a press association reported a substantial drop in the number of tumbling centers operating in the Los Angeles area, where the fad began. This was prior to some medical authorities concern with the number of injuries suffered by Trampoliners.

Whether the Trampoline craze is actually waning, or just taking a breather before a bigger spurt, remains a matter for speculation. It is quite possible that Southern Californians are simply turning their attention elsewhere while the rest of the country catches up.

Reasons for Popularity

A Trampoline, a piece of resilient canvas spread over a shallow pit, or elevated by a supporting frame, requires some degree of skill in proper timing and muscular control. It has become a popular diversion attractive especially to children and teenagers. Many centers are located at shopping centers and thus provide entertainment for youngsters while their mothers shop.

A tumbling center customer buys time. The charge per unit of time is relatively small. Unlike club karting, the practitioner need not make an investment.

Pattern of Growth

The recent growth, unlike that of karting, has been almost entirely commercial. Centers developed at roadside commercial areas, similar to those which attracted miniature golf courses and driving ranges in the past.

The capital investment of the tumbling center operator is relatively small. One published estimate in 1959 indicated that the minimum outlay was about $7,000, about half of which was for insurance. Despite this low investment, selection of a site is crucial. The operator must count on recovering his investment quickly, for the sport's popularity could evaporate quickly in the capricious shift of public interest.

There are many parallels with karting, apart from the fact that both have utilized shopping center parking lots. The most striking is the small amount of land needed for each facility. The problems are the same: safety, noise, and land use control. There is, however, little likelihood that tumbling clubs will emerge.


It is only recently that frowns have wrinkled the brows of medical men looking at bouncing and its effects. Some cities which ignored the activity as a commercial one, not requiring regulation, found that people were being injured, with resulting complaints to city hall.

One planning agency reported:

Due to the overnight acceptance by the general public of this new type of recreational activity, we were flooded with requests to build these centers and had no regulations for the protection of the safety and welfare of the general public.

Several serious accidents occurred by reason of alleged dangerous methods of construction and installation; therefore immediate action was taken.

The municipalities have taken two approaches, both endorsed by the Trampoline Rebound Tumbling Association (the operators' trade association). However, it should be noted that many municipal regulations have been somewhat more stringent, particularly in relation to padding on equipment and the qualifications of supervisors, than the recommended legislation of the association.

Construction. Standards have been established for materials to be used; support and placement of the trampolines; size and relationship to other trampolines at the center; kind and amount of padding to be used, and the like. (Typical provisions as contained in the ordinance of the City of Bakersfield, California, are shown in Appendix D.)

Supervision. The industry, through its association, has agreed that there must be supervision of participants. Several ordinances have specified that there be at least one supervisor on the premises for each unit of 12 Trampolines in operation. In some cities, the head supervisor (or one of the supervisors) must be at least 21 years old. It is sometimes specified that these supervisors be trained or proficient in the use of bouncing equipment. There must be a public address system so that over-energetic bouncers can be warned to restrain themselves. Some specifically require the operator to ground customers who are careless.

Related provisions require that certain resources be on hand: a telephone to call medical assistance if needed, a fence high enough to insure that people would not use the facilities after hours without the owner's permission, and adequate lighting if the center is to be used at night.

Zoning. Since tumbling centers are overwhelmingly commercial activities, their relation to zoning ordinances is clear-cut in most cases. There is, for example, no non-profit club aspect as there is in the case of karting. Yet there is the dilemma of characteristics which do not conform entirely to what was envisioned when the zones were established.

If located too close to residences, tumbling centers might be offensive in a way that stores would not be. They attract large crowds (some centers even provide bleachers for spectators). The use of a public address system at a shopping center introduces an entirely new characteristic. Many centers have a continuous program of canned music blowing through the P.A. system. Operation may terminate later than the stores at the center.

It is for these reasons that most cities permit tumbling centers in the least restricted commercial zones. A survey5 undertaken by the Albuquerque City Planning Commission, summarizing the practice and experience of other cities reported that the Los Angeles, California, zoning ordinance (1955) permits tumbling centers in the general commercial zone or other less restricted zones. The more restrictive commercial zones require that uses be conducted entirely within enclosed buildings and do not permit recreation or amusement enterprises.

The Phoenix, Arizona, zoning ordinance (1955) permits tumbling centers in the intermediate commercial zone by special permit after a public hearing has been held by the Board of Adjustment. The off-street parking plan must be approved by the city traffic engineer.

Centers are permitted in the most restrictive commercial districts in St. Louis, Missouri (1950); Reno, Nevada (1959); and Scottsdale, Arizona (date ?). At the time of the Albuquerque survey, Reno reported that no tumbling centers had been constructed. This lack of activity may have been, in part, caused by the requirements that a tumbling center operator must furnish. Commercial zone toilet facilities, fencing, drinking fountains, an office and equipment building, off-street parking, ground lights, and a 10 P.M. limit for operation are required by the city. Public address systems and lighting appeared to be problems in Scottsdale. The noise problem was solved through the installation of several small speakers similar to those at drive-in-theatres. These speakers are scattered throughout the center and controlled through the office. The lighting problem, however, has yet to be solved, according to the respondent. The city has recommended that a conical shield be installed over each light bulb in order to deflect light downward rather than outward.

In spite of such requirements, permitting tumbling centers in a restricted commercial zone seems to be a questionable practice. Their operating characteristics are not compatible to those uses normally considered permissible in neighborhood business zones.

Trampoline sales offices, however, present a different problem than the tumbling centers. Such offices with an outside display area have, in one instance, caused difficulties because of inadequate treatment of outdoor displays in the district regulations of a zoning ordinance. It is quite common for zoning ordinances to require that all uses in certain business zones be conducted entirely within enclosed buildings, or to require that all be conducted within enclosed buildings except certain enumerated uses that can scarcely be conducted indoors. The "conditions to use" for each of the commercial zones in the Fontana, California, zoning ordinance (1957) are unusually well defined.

"C-1" Neighborhood Commercial Zone: "All business, service storage or processing shall be conducted wholly within a completely enclosed building except the following: Automobile parking, off-street loading and gasoline pump islands."

"C-2" Community Commercial Zone: . . . except "Automobile parking, off-street loading, gasoline pump islands, nursery stock, public utility structures and permitted amusement establishments."

"C-3" Central Commercial Zone: same

"C-4" General Commercial Zone: . . . except "Automobile parking, off-street loading, gasoline pump islands, permitted amusement establishments, hoists for servicing of automobiles, nursery stock, public utility structures, used car lots, equipment rental, trailer sales and rentals and other uses specifically approved by the planning commission."


The two activities discussed in this report have several common characteristics:

1. There is a low demand for land area, and land normally given over to other uses can be pressed into service. This is demonstrated by the fact that shopping center parking lots have been utilized by karters and Trampoliners.

2. Safety, noise, and land use control are major considerations.

It seems reasonable to conclude that any fad that presents problems for planners will be similar in nature. An examination of the kinds of marginal land use previously made to accommodate the public's interest in other activities (miniature golf) for example) will bear out this conclusion, we believe.

The planning agency should deal with a new fad on several grounds.

There must be a decision as to what existing zones may be used. For example, karting and Trampolines may create few problems in a large regional shopping center. However, the neighborhood shopping center, by its very nature, is too close to residential areas. Noise, traffic, and related problems must be examined carefully in each case. It therefore follows that zoning ordinances must provide review machinery which will permit consideration of the special uses involved in a new and popular activity. The conditional use permit procedure is a good one to use in such a case.

The planning agency must be aware of all community activities, even the more frivolous ones. This awareness must exist if the agency is to be able to recognize the areas requiring legislation, as in the safety requirements for Trampoline centers. Those communities which face the problems first will be at a disadvantage, of course, because they will have no examples from other cities to use. However, each city must make a critical evaluation early in the game so that supplemental legislation can be framed if any is found to be necessary.

Similarly, there must be an early evaluation of parking needs. There is little to guide the planning agency in setting up off-street parking regulations; it must improvise and attempt to predict a demand and set supply requirements. Some guidance may be obtained by observing peak hour parking demands, and keeping them on record for future use.

One of the best protections that a community has against these, or any future fads, is the permissive zoning ordinance. Under this type of ordinance, all uses not specifically permitted in a zone are automatically prohibited. In a city with such an ordinance, there would have been no mention of a "kart track." Hence, it would have been prohibited until such time as the ordinance was amended to permit it, with proper safeguards. In such a case, if the decision of the city is not to permit kart tracks, it need take no further action.

Appendix A

MARCH 1960

A local insurance agency stated that go-cart operations can be insured for bodily injury and property damage, but only under certain circumstances. These conditions center primarily on the construction and type of the go-cart itself and on the safety provisions provided for the spectators. Rudiments of the insurance requirements are incorporated in the conditions set forth later in this memorandum.

It appears that the proposed go-cart use is somewhat different in nature from the bulk of the uses either permitted in "R-1" or allowed as conditional uses. In general, all of these uses are quiet, free from excessive traffic generation, excessive dust, etc.

Considerable controversy has arisen in the city due to the operation of go-carts in the parking lot of a television studio and at an amusement park. The complaints arising from such use in these areas have come primarily from the residential areas nearby. Most of the complaints concerned:

1. Noise from the operation of the go-carts;

2. The traffic problems generated from the spectator interest in the sport.

The applicant has indicated that he intends to use the go-carts for recreational uses only and does not intend to allow racing or competition of any nature. If such use is permitted in a basically residential area, such as the "R-1" District, then it would seem appropriate to consider such conditions as are necessary to provide for the public welfare, privacy, and convenience; and to eliminate, insofar as possible, any nuisance which may be created by the operation of go-carts.

In view of the foregoing, the Planning Department suggests that the following conditions be considered:

1. Construction of a chain link type of fence at least four feet in height, mounted on no less than 5 ½  foot steel posts, such posts to be located at intervals no greater than sixteen feet apart, such fence to surround the go-cart roadway. Any gates in the fence shall be kept closed during the operation of any go-cart.

2. The go-cart roadway shall have at its outer perimeter, an adequate bumper guard (spring mounted bumpers, baled hay, or similar material) to stop or deflect go-carts which may be out of control.

3. All go-carts shall:

A. Have bumpers of a non-metallic material;
B. Provide proper seating for the occupant;
C. Have a governor on the motor or engine which shall limit the speed of such go-cart to a maximum of 10 MPH;
D. Provide a plastic safety helmet for the use of the occupant;
E. Have a clutch drive mechanism. No direct drive go-cart shall be allowed;
F. Have no engine or motor larger than 2 ½ HP;
G. Have a muffler in good condition to prevent undue noise;
H Be prohibited from having sirens or bells or other sound projecting device.

4. All bulk storage of fuels and lubricants shall be outside the go-cart roadway area and shall be stored in such manner as may be directed by the Fire Chief of Sedgwick County.

5. The hours of operation shall be only between 8 A.M. and 10 P.M. during week days and Saturday and between 12 noon and 10 P.M. on Sundays.

6. The go-cart roadway shall be so surfaced or treated as to prevent blowing dirt, sand and/or dust.

7. All lights shall be directed away from adjacent housing.

8. Ingress and egress to and from the spectator area shall be a roadway of at least 24 feet in width; surfaced or treated to prevent blowing dust, sand, and/or dirt.

9. Signs advertising such operation shall be limited to 12 square feet in area, and the vertical dimension shall not be greater than twice the horizontal dimension nor less than half the horizontal dimension; and such sign shall not be illuminated by artificial light of any kind.

10. No public address system shall be permitted.

11. The sale of food and beverages shall be prohibited; except that soft drink and candy dispensing machines shall be permitted.

12. All vehicles operated on the track shall be owned by the holder of the conditional use permit.

13. No racing shall be permitted.

It is suggested that the above provisions are the minimum requirements for this type of activity; if it is to be compatible with the residential area in which it is located.

Appendix B


Tracks operating as an amusement or on a "rental ride" basis shall be subject to the following rules:

PREAMBLE: The intent of the following specifications is to provide safe recreation. Compliance with these specifications does not bind the United States Kart Association, Inc., to accept any or all applications for membership. Obvious and/or unusual combinations of these specifications used to circumvent their intent will be cause for rejection.

These specifications do not apply to tracks constructed prior to June 1, 1960. Tracks constructed prior to June 1, 1960, as well as any others which do not specifically meet these specifications should make application to the Executive Director for special consideration.

TRACK SURFACE: The track should be a well graded surface of durable non-skid material treated to minimize dust. Either dirt or hard surface tracks are acceptable. The track should be free of holes, rough spots, clods and loose particles. Gravel surfaces are not permitted.

TRACK DESIGN AND LAYOUT: Both oval and road-type courses are eligible. Each type must be constructed and maintained to allow safe operation of karts and adequate spectator protection. Specific specifications are as follows:



1. Minimum, 1/25 mile.
2. Maximum, 1/4 mile.
3. Measurement will always be made on the inside edge of the track and will continue around the track on the same edge.


1. Minimum, 50 feet.
2. Maximum, 200 feet.


1. Straights:

Minimum acceptable, 16 feet.
Maximum acceptable, 34 feet.
Recommended width, 20 feet.

2. Turns should enlarge to a minimum, half way around, of 5 feet more than the straight width. The maximum acceptable width is 39 feet.

Minimum pitch is 0 degrees. Pitch when used must always be from the inside to the outside of the track surface. Flat tracks with no banked turns are strongly recommended.

TURNS: Radius maximum is unlimited. The minimum inside radius allowed for a road type course is 10 feet. The minimum inside radius allowed for an oval course is 15 feet. A minimum of one turn for every 250 feet of total track length is required on road courses. Sixty degrees change of direction is the minimum degree of change to qualify as a turn.

OPPOSING SECTIONS: A minimum of 25 feet (10 feet where kart speed is limited to a maximum of 12 MPH) must be maintained between sections of the course where karts are traveling in opposite directions except where such sections are no longer than 20 feet AND precede and follow a turn.



Minimum, 10 feet.
Maximum, width of track.

LOCATION: The pit entrance and exit must enter and leave the course at points out of the normal running path and at the slowest portion of the track that is practical. Pit entrance and exits must always be on the outside of the track.

SAFETY APRON: A minimum safety area 20 feet (10 feet where kart speed is governed to 12 MPH) wide must be maintained around the entire track on all sides except in areas where the track is parallel to the perimeter in which case the safety apron may be reduced to ten feet. Tracks with less than these minimum safety areas will require special inspection and although slight variance will be considered the rental kart classes permitted on the track may be restricted.

This area must be free of ditches, holes, trees, and all other obstacles and must be graded flat with the exception of a one degree maximum for drainage. Where natural land areas lend themselves to it, a maximum positive grade of 10 degrees is permitted, however, it must blend at junction of the track with a smooth shallow radius. This surrounding area should also be graded flush with the edges of the track and preferably seeded or paved. Dusty conditions are not acceptable.

Necessary timing, official stands and/or safety equipment should be placed at a distance of 10 feet off the course (minimum of 5 feet) and protected by hay bales placed two feet away from and around the obstacle. Other than this protective measure, no hay bales, railing, walls, tires, pylons, etc., will be permitted in the safety apron except where a fence is within fifty feet of the outside of a turn, hay bales shall be placed two feet from the fence.

Pit Areas

It is permissible, for long distance races, to have a pit area adjacent to a straightaway. The pit activity must take place a minimum distance of 20 feet from the nearest edge of the track.

Entrance. The entrance between the course and pit area must contain some form of speed reducing factor either by relation to the track or the design of the exit itself. A line clearly visible to each driver, must be drawn across the pit entrance and exit. Drivers entering the pit area from the track must stop at this line, turn engine (or engines) off and push their karts to their respective positions in the pit area. Drivers leaving the pit area must push their karts to this line before starting the engine (or engines). There will be no exceptions to this rule. Pit entrance and exits must always be on the outside of the track unless access over or under the track is provided.

Safety Apron. The minimum safety area is 35 feet, except that it may be reduced to a minimum of 20 feet where the track is parallel to the perimeter area. Timing, official stands, and/or safety equipment should be placed at a distance 20 feet off the course (minimum of 10 feet).

Pit Area. In addition to the requirements in Appendix B:

1. One driver and two pit personnel, or a total of three persons per kart is the maximum number of persons per kart in the pit area.

2. As differentiated from the pit area (where karts are kept between events) a working pit area is permitted parallel to the track proper, where karts may be serviced during long distance events. It is mandatory that the entrance to this area be not less than 10 feet wide, with a minimum change of direction of two 45 degree turns, and a maximum inside radius of 15 feet. Each kart in an event using this type pit must have a pit 8 feet by 10 feet.

*Some cities have spelled out their requirements for experience in the use of rebound tumbling equipment. Riverside, California, for example, requires that the supervisor demonstrate his ability to perform the following maneuvers: 1) feet bounce, 2) knees bounce, 3) seat-drop, 4) hands and knees bounce, 5) front-drop, 6) back drop, and 7) such other maneuvers as the Park and Recreation Department in its judgment shall require. He must also demonstrate to the department a knowledge of the safety requirements of the code and such other safety rules it deems pertinent. The code sets up an appeal procedure, a public hearing by the City Council.
