shall be filled with non-combustible material the full thickness of
the wall and six (6) feet one (1) inch or more above, between and
below such members.
7.
Reinforced
concrete walls of monolithic construction shall not be less than two-thirds
(2/3) the thickness specified above for brick walls except that no

A.
Parapets
eight (8) inches or more in thickness shall be extended a minimum
of eighteen (18) inches above the roof level on those walls which
are required by this Article to be of masonry construction, except
as specifically exempted below. All parapeted walls shall be suitably
coped. Parapets shall not be required on:
1.

A.
For the
purpose of preventing the spread of fire from building to building
communicating openings in fire walls and certain openings in exterior
walls required by this Article to be of masonry or equivalent construction
shall be protected by approved fire doors, approved fire windows or
other approved means satisfactory to the City Fire Chief.
B.
Protection
shall be required for conditions as follows:
1.
When
communicating openings are located in fire walls separating buildings.
In such cases, communicating openings shall be protected on each side
of the wall by fire doors approved for the protection of openings
in fire walls.
2.
When
openings are located above the first story in an exterior wall facing
on a street less than thirty (30) feet measured from building line
to building line.
3.
When
openings in an exterior wall are less than thirty (30) feet distant
in a direct unobstructed line from an opening in another building.
Protection shall not be required where openings in exterior walls
face in the same direction.
4.
When
openings in an exterior wall are above and are less than thirty (30)
feet distant from any part of a neighboring roof of a building of
other than fire-resistive construction (reinforced concrete frame,
floors and roof or their equivalent).
[CC 1974 §505.090; Ord. No. 845 §209, 1969]
Firestopping in all classes of buildings shall be arranged to
cut off all concealed draft openings, such as at floors, ceilings,
roofs and attic spaces and shall form effectual fire barriers horizontally
and vertically. In buildings of non-fire-resistive construction, wood
inches in thickness, nominal dimension, may be used; in other types
of construction approved non-combustible material shall be used.
[CC 1974 §505.100; Ord. No. 845 §210, 1969]
Where it is desire to install a new ceiling below the level
of an existing ceiling, all existing intervening ceilings below the
floor or roof immediately above must first be removed. For the purpose
of this Section, a ceiling is defined as the overhead inside lining
of a room whereby a concealed space is formed below the floor or roof
to which it is attached. Finish applied directly to the bottom of
a floor or roof without forming a concealed space is not to be interpreted
as a ceiling under this Section.
[CC 1974 §505.110; Ord. No. 845 §211, 1969]
All workmanship and building materials shall be of good quality
and shall conform to specifications which the City Fire Chief prescribes.
The more generally standard specifications for quality of materials
are those of the American Society of Testing Materials. All parts
of every building shall be designed to safely carry loads to be imposed
thereon and shall in all other respects conform to good engineering
practices.
[CC 1974 §505.120; Ord. No. 964 A §§1 — 3, 7-1975]
A.
That
the City Fire Chief shall review all building permit applications
for new construction or substantial improvements to determine whether

a proposed building site is in a location that has a flood hazard,
any proposed new construction or substantial improvement (including
prefabricated and mobile homes) must:
B.
That
the City Fire Chief shall review subdivision proposals and other proposed
new developments to assure that:
1.
All
such proposals are consistent with the need to minimize flood damage,
2.
All
public utilities and facilities, such as sewer, gas, electrical and
water systems are located and constructed to minimize or eliminate
flood damage, and
3.
Adequate
drainage is provided so as to reduce exposure to flood hazards.
C.
That
the City Fire Chief shall require new or replacement water supply
systems and/or sanitary sewage systems to be designed to minimize
or eliminate infiltration of flood waters into the systems and discharges
from the systems into flood waters and require on site waste disposal
systems to be located so as to avoid impairment of them or contamination
from them during flooding.
