13-96-1170  Ancillary spaces.
   Ancillary spaces shall be contiguous to the shooting range and directly support the operations of the shooting range. These spaces shall be separated from the shooting range with appropriate means to diminish contamination from the by-products of the shooting range and be protected from any projectiles straying from the shooting range.
(Added Coun. J. 7-6-11, p. 3073, § 8)
13-96-1180  Occupancy requirements.
   (a)   A shooting range facility occupancy classification shall be as provided in Chapter 13-56, based on the occupancy of the shooting range facility's ancillary spaces. The most restrictive ancillary space occupancy which is greater than 5% of the total shooting range facility area shall govern the occupancy classification.
   A shooting range facility shall comply with the applicable code requirements for the specific use of the space as determined by Chapter 13-56 and this section. The amount of area per person shall be determined by Sections 13-56-310 and 13-56-320, or as otherwise determined by this Article.
   (b)   A shooting range shall be a Miscellaneous type J occupancy. The occupancy calculation to determine the occupancy count of the shooting range shall be determined by calculating the amount of area behind the firing line between the firing line and the perimeter of the enclosure protecting the remaining shooting range facility from projectiles and dividing that area by 20 square feet. Where the firing line is not stationary, the area shall be based on the average distance between the extreme firing line locations and the perimeter of the shooting range enclosure.
   (c)   The occupancy count shall be used to determine the required number and size of the exits. The area between the firing line and the bullet trap/backstop shall be unoccupied and shall not be counted in the occupancy load calculations or be considered for exiting travel distance.
(Added Coun. J. 7-6-11, p. 3073, § 8)
13-96-1185  Height and area limitations.
   (a)   The height and area limitations of a shooting range facility shall be as provided in Chapter 13-48, and the occupancy classification of the shooting range facility shall be determined in section 13-96-1180. In calculating the maximum allowable height and area of the shooting range facility, the total area in the shooting range, including the area from the firing line to the wall behind the backstop/bullet trap, shall be included in such calculations.
   (b)   The maximum height of every shooting range erected or constructed within a new or existing building shall be one-story or 20 feet, whichever is less, and the maximum area shall match the limitations for H-3 garage classifications in Table 13-48-070.
(Added Coun. J. 7-6-11, p. 3073, § 8)
13-96-1190  Shooting range facility requirements.
   (a)   The shooting range facility must comply with all applicable code sections as determined by the occupancy classification. Where the ancillary spaces are under the direct control and management of the owner of the shooting range, no mixed occupancy separation is required between the shooting range and the ancillary spaces. Where the ancillary spaces are not under the direct control and management of the owner of the shooting range, or where the shooting range is constructed without ancillary spaces, the mixed occupancy separation shall be as set forth in Table 13-56-280. The shooting range occupancy classification to determine required mixed occupancy separations shall be Class E Business. The need for mixed occupancy separations is not determined by the amount of area occupied by the ancillary spaces as a percent of the total area of the shooting range facility.
   (b)   Exiting for the shooting range facility shall not be through the shooting range.
   (c)   (1)   The shooting range facility may include the following uses: office space, mercantile, training, classroom or spectator space, general patron use space, locker rooms including showers, range master booth, storage of ammunition, and storage of firearms.
      (2)   The shooting range facility shall include the following uses:
         a)   a shooting range;
         b)   security entrance;
         c)   toilet facilities in compliance with Chapter 18-29 and Section 13-96-1220; and
   (d)   All occupancies within the shooting range facility must be protected from any projectiles straying from the shooting range.
(Added Coun. J. 7-6-11, p. 3073, § 8; Amend Coun. J. 6-25-14, p. 83727, § 9)
13-96-1200  Shooting range requirements.
   (a)   Every shooting range shall be separated from the rest of the shooting range facility or other occupancies with a separation that prevents projectiles from straying from the shooting range.
   (b)   Every shooting range shall comply with the following:
      (1)   area requirement – the shooting range shall have minimum ceiling height of 8 feet. The area between the firing line and the rear wall shall be at a minimum adequate to accommodate a designated exit path beyond the depth of the area occupied by the shooting range patron and any appurtenances. The exit path shall be in addition to area required for shooting range patrons to easily and directly move from one shooting booth or shooting position to another along the firing line without disturbing another shooting range patron and the area required for the range master to monitor operations;
      (2)   sound control – the noise emanating from the shooting range to areas outside of the shooting range facility is subject to Chapter 8-32, Sections 8-32-010 through and including 8-32-170, Noise and Vibration Control. The maximum noise emanating from the shooting range facility shall not be more than 55 dB when measured from a distance of 100 feet or more from the source, or 70 dB when measured from a distance of 10 feet or more from the source. The shooting range shall conform to the requirements of The Occupational Noise Exposure Standard Section 1910.95 of 29 C.F.R. Part 1910 and shall be designed and constructed to contain noise generated from the discharge of firearms.
      (3)   special ballistic protectives – the shooting range shall have ceiling baffles, deflector plates and floor guards of appropriate materials, such as steel plate covered with wood or other materials, which are designed with sufficient bullet resistive strength, thickness, and configuration to function safely for the type and caliber of firearms and ammunition used within the shooting range. Such protectives shall be permanently located and anchored to protect the building structure, lighting fixtures, HVAC ductwork and appurtenances, plumbing hose bibbs, floor drains and cleaning apparatus, ceilings, target carrier apparatus or other range appurtenances or assemblies to protect against ricochets or back splatter and to re-direct the projectiles to the backstop;
      (4)   bullet trap/backstop – the shooting range shall have a permanent, fixed, proprietary manufactured bullet trap system capable of stopping and containing the bullets or projectiles from any firearms discharged at the shooting range. The bullet trap shall be designed and constructed of appropriate bullet resistive, durable materials, such as steel plate. The bullet trap shall be capable of functioning safely for the type, amount and duration of firearm usage at the shooting range. The bullet trap shall cover the entire space between the two side walls of the shooting range and provide complete coverage for all firing positions from floor to the underside of the structural ceiling assembly. Bullet trap systems which utilize rubber chunks, blocks, sheets, layered rubber, laminated carpeting or other materials potentially subject to combustion, shall be fire-treated to be fire-resistive and meet the flame spread requirements of Class 1, unless the building is equipped with an approved automated sprinkler system, in which case Class 2 requirements shall apply. Mobile or temporary bullet traps/backstops are prohibited;
      (5)   exit pathways – exits and exit pathways serving the shooting range shall not require occupants to pass beyond the firing line and cross through the firing range area. The area from the firing line to the back of the backstop/bullet trap shall not be included in the exiting travel distances. No exits shall be located in this area;
      (6)   no doors or windows downrange – no doors or windows shall be located in the shooting range in the space between the back face of the bullet trap to a point five feet behind the firing line located the farthest distance from the bullet trap/backstop;
      (7)   floors, ceilings, and walls – the floors, ceilings, and walls of every shooting range shall be constructed of smooth non-porous materials to facilitate effective maintenance and cleaning and removal of lead particulate.
      (8)   shooting booths – where shooting booth separations are provided, the shooting booth panels shall be constructed of permanently fixed, cleanable, non-porous materials. The shooting booths shall be constructed to provide an impenetrable protective barrier between people at the shooting booths and to protect against the effects of ejected bullet casings and muzzle blast;
      (9)   range master booth – where a range master booth is provided, the shooting range shall be limited in size to the area that can be directly visible to the range master at all times. The range master booth shall be constructed to provide:
         (i)   protection from any projectiles straying from the shooting range;
         (ii)   clear visibility of all firing positions at the shooting range;
         (iii)   ready access to the shooting range;
         (iv)   acoustical protection and separation for the range master;
