5.40.030 Construction standards.
It is unlawful for any person to manage, conduct, carry on or own the business of operating a rebound-tumbling device center unless:
A. Each rebound-tumbling device shall have been installed level on a reasonably level space with the following minimum unobstructed spacing from the inside edges of the frame, except for necessary light poles and support:
1. From the ends to the nearest fence, building or other similar construction, five feet;
2. From the sides of the fence, building or other similar construction, four feet;
3. Between the ends, four feet;
4. Between the sides, three feet, except when arrangements have been made to the satisfaction of the planning commission, which will provide for comparable safety and will provide for supervision and training as may be required.
B. The distances in subsections (A)(1) and (A)(2) of this section may be reduced when such surfaces are padded and the proposed plans are approved by the planning commission.
C. The area surrounding the rebound-tumbling devices shall have been surfaced to prevent a dust nuisance and shall have a reasonably level surface of pea gravel or equivalent type of material from a safety and dust control standpoint.
D. The pits over which the rebound-tumbling devices are strung shall not be over four feet deep nor less than 39 inches deep at the center, and so constructed as to preclude the touching of the bottom thereof while anyone is jumping, bouncing or tumbling upon, or performing tricks, stunts or acrobatics upon or otherwise using the rebound-tumbling devices. The pit bottom shall be covered with not less than four inches of gravel or equivalent material which will aid in seepage or drainage of rainwater without ponding, except in porous, sandy or gravel soils.
E. The rebound-tumbling device center shall be enclosed with a substantial metal or equivalent fence at least five feet high and of a type which is difficult to climb. The entrances shall be equipped with secure locks for use when the facility is not attended.
F. The rebound-tumbling device center shall be equipped with an adequate lighting system to discourage use and entry when not attended and so that for use at night the whole area of the facility shall be well lighted.
G. Each rebound-tumbling device is strung over a pit level with the ground, and the rebound-tumbling device bed shall be at least 12 feet long and six feet wide in size.
H. The exposed framework of each rebound-tumbling device, whether it be of metal, wood, plastic or other rigid structure, shall be completely covered with padding which is of obvious or proven resilience to afford reasonable protection from shock; such padding shall be secured to be effectively kept in place; and it shall be reasonably durable and kept in a clean condition.
I. Springs, cables, supports for webbing or beds and their connections shall be so designed, installed and maintained to avoid any projections or protrusions which would tend to cause a cut of the skin. Adequate measures shall be taken to prevent flying of broken metal springs. The maximum uncovered space from the frame to the bed shall not exceed 20 inches.
J. The beds shall be made of substantial material and be so fabricated as to reasonably resist tearing or rupture which might cause accidents or injuries. The center of each bed shall be plainly marked with a cross or bull’s-eye to aid users in keeping toward the center.
K. No rebound-tumbling device commonly known in the trade as a “hot bed” shall be installed in a rebound-tumbling device center without the written consent of the planning commission. (Ord. 310 § 3, 1960).
