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.
