Any use established hereafter in any zoning district shall be so operated as to comply with the hazard abatement performance standards set forth in this Division unless otherwise specified. However, within Planned Development Districts Nos. 23 and 24, provisions stated within those districts shall apply when in conflict with the hazard abatement standards of this district.
Fire and explosive hazards shall be controlled as set forth in this Section.
A. Storage or Manufacture of Materials or Products Which Decompose by Detonation Not Permitted. Activities involving the storage or manufacture of materials or products which decompose by detonation are not permitted unless licensed by the City of Franklin. If such activities are permitted by City of Franklin license, such activities shall take place exclusively in the M-2 District.
B. Storage, Utilization, or Manufacture of Materials Ranging from Free to Active Burning May be Permitted With Conditions. The storage, utilization, or manufacture of materials determined to be highly volatile by the Fire Chief is permitted in the M-2 District under the following conditions:
1. Location. All storage, utilization, or manufacture of such materials or products shall be within completely enclosed buildings or structures having noncombustible exterior walls.
2. Setbacks and Sprinkler Protection. All such buildings or structures shall be set back at least 40 feet from property boundaries unless greater standards are required by the specific zoning district in which said materials are located, or, in lieu thereof, shall be protected throughout by an automatic sprinkler system complying with standards for installation prescribed by the National Fire Protection Association.
3. Noncombustible to Moderate Burning Materials. The storage, utilization, or manufacture of materials ranging from noncombustible to moderate burning (as determined by the Zoning Administrator) is permitted.
4. Materials or Products Which Produce Flammable or Explosive Vapors. Materials or products which produce flammable or explosive vapors or gases under ordinary weather temperatures shall not be permitted in this district, with the exception of the following, which are permitted:
a. Materials required for emergency or standby equipment.
b. Materials used in secondary processes which are auxiliary to a principal operation — such as paint-spraying of finished products.
c. Flammable liquids and oils stored, sold, and used in conjunction with the operation of an automobile service station and customarily required or used in such operation.
5. Manufacture, Possession, Storage, Transportation, and Use of Hazardous Materials. All manufacture, possession, storage, transportation, and use of hazardous materials which include explosives and blasting agents, flammable and combustible liquids, liquefied petroleum gas, and hazardous chemicals shall be required to comply with all applicable State and local fire codes or as set forth in the National Fire Protection Association's Fire Protection Handbook — 1986 Edition as amended, whichever is stricter.
6. No Storage Allowed Within One-Hundred-Year Recurrence Interval Floodplain. Any permitted structural storage facilities for chemicals, explosives, buoyant materials, flammable liquids and gases, or other toxic materials which could be hazardous to public health or safety, shall be located at elevations a minimum of four feet above the one-hundred-year recurrence interval flood elevation.
The following standards shall apply to heat and humidity.
A. Location. Any activity producing intense heat shall be conducted within an enclosed building in such a manner as not to raise the temperature of the air beyond the site boundary line.
B. Increases in Humidity in the Form of Steam or Moist Air from Cooling Towers or Equipment. Increases in humidity in the form of steam or moist air from cooling towers or equipment shall be controlled so that they do not create an ice hazard. Cooling towers shall be controlled by either reheating the plume or using a closed system.
C. Declaration of Public Nuisance. Any operation producing intense heat or humidity shall be performed within a completely enclosed building and effectively screened in such a manner as not to create a public nuisance or hazard along property boundaries.
All uses shall conform to the following specified standards pertaining to radioactivity.
A. Maximum Concentrations of Radioactivity Permitted. The maximum permissible concentrations of radioactivity that can be released shall be subject to the regulations of the State of Wisconsin, and any federal agency having jurisdiction. In the case of conflict, the most restrictive requirements shall govern.
B. Storage of Radioactive Materials. Radioactive materials shall be stored in fireproof containers made of steel and concrete, but shall not be stored in containers made of lead or other low melting metals or alloys unless completely encased in steel.
C. Medical Sources of Radiation Residues. Medical sources of radiation residues, such as X-ray machines, gamma and neutron sources, and pharmaceutical isotopes which are used for diagnostic and therapeutic purposes, shall be permitted when located within a hospital, clinic, medical or dental office, or medical research facility. Other uses of radioactive materials shall be limited to measuring in X-ray and similar apparatus, and in connection with the processing and preservation of food.
Where floodproofing by means of elevating on fill is deemed inappropriate or impractical, and where floodproofing by means other than filling is permitted, floodproofing measures shall be in accordance with the following:
A. Floodproofing Measures. Floodproofing measures shall be designed to:
1. Withstand the flood pressures, depths, velocities, uplift and impact forces, and other factors associated with the one-hundred-year recurrence interval flood.
2. Assure protection to an elevation at least two feet above the elevation of the one-hundred-year recurrence interval flood.
3. Provide anchorage of structures to foundations to resist flotation and lateral movement.
4. Ensure that the structural walls and floors are watertight and completely dry without human intervention during flooding to a point at least two feet above the elevation of the one-hundred-year recurrence interval flood, and the interior remains completely dry during flooding without human intervention.
B. Permit or Variance. No permit or variance shall be issued until the applicant submits a plan or document certified by a registered professional engineer or architect certifying that the floodproofing measures are adequately designed to protect the structure or development to a point at least two feet above the elevation of the one-hundred-year recurrence interval flood.
C. Additional Floodproofing Measures. Floodproofing measures may include, but are not limited to, any one or combination of the following measures:
1. Reinforcement of walls and floors to resist rupture or collapse caused by water pressure or floating debris.
2. Addition of mass or weight to structures to prevent flotation.
3. Placement of essential utilities above the flood protection elevation.
4. Installation of surface/subsurface drainage systems, including pumping facilities, to relieve external foundation wall and basement floor pressures.
5. Construction of water supply wells and waste treatment and collection systems to prevent the infiltration of floodwaters into such systems.
6. Cutoff valves on sewer lines and the elimination of gravity flow basement drains.
7. The additional floodproofing measures identified in the definition of "floodproofing" in § 15-11.0103.
