Plan Review Comments for Storage Building
Pro[ect Summary:
Proposed Use:
Building size:
Occupancy classification:
Type of Construction:
Storage:
Storage Building
8,750 square feet
S-2 (as determined by the Building Department)
Type III-N
Equipment & Livestock/Maturuity Area
Public Water Supply Required-
1. The water supply required by Appendix III-A of the 1997 Unifoma Fire Code
given building size of 8,750 and construction type of III-N would be 2,000
GPM for a 2-hour duration at a minimum residual pressure of 20 psi. Two
fire hydrants are required to deliver this flow and are typically spaced on 450'
centers. The closest fire hydrant is usually 250' from the driveway or point
on the street.
Options to reduce this requirement:
1. This frre flow requirement could be reduced by providing a area separation
wall as defined in Appendix III-A Section 4.2 "Portions of buildings which
are separated by one or more four-hour area separation walls constructed in
accordance with the Building Code, without openings and provided with a 30'
inch parapet, are allowed to be considered as separate fire areas. If this
separation could be provided and the fire area reduced to 7,900 square feet,
one fire hydrant would be required and the maximum spacing would be
increased to 500'.
2. Provide an approved "Rural Water Supply" per the National Fire Protection
Association Standard 1142. Calculating Minimum Water Supply required is a
follows: Classification of Occupancy Hazard Type 5 "Farm storage buildings,
such as corn cribs, dairy barns, equipment sheds, and hatcheries".
Classification of Construction Type- Type III Construction shall be that type
in which exterior walls and structural members are ... "limited-combustible
materials" Exterior Bearing Walls are required to be 2-hour construction and
supporting a roof only. The Classification Number is then 1.0
The formula is then the total building volume in cubic feet divided by the
occupancy classification of 5.0. Assumptions average building height of 23'
with a total building volume of 201,250 would require a rural water supply of
40,250 gallons stored in an approved manner.
Other miscellaneous requirements:
Premises Identification -
1. Ensure that the address for this building is prominently posted and visible from, and
face towards, E. Franklin
2. The address numerals shall be at least 6" tall and their color shall contrast distinctly
with their background.
Fire Extinguishers-
1. Portable Fire Extinguishers shall be installed in occupancies and locations as set
forth in this code and as required by the Chief. UFC 1002.1 Fire Extinguishers
shall be of the 2A 10BC size and have the top of the extinguisher hung 3~ to 5' off
the floor. The fire extinguishers locations shall be by each front door, the travel
distance shall not exceed 75' to a fire extinguisher.
General Requirernents-
1. Storage shall not exceed 12' in height. UFC Section 209
Ceiling clearance shall be maintained at no less 2' in unsprin!ded buildings.
UFC 1103.3.2.2
ANY OVER LOOKED HAZARDOUS CONDITION AND/OR VIOLATION OF THE
UNIFORM BUILDING AND FIKE CODE DOES NOT IMPLY APPROVAL OF SUCH
CONDITION OR VIOLATION.

FIRE HYDRANT EOCATIONS AND DISTRIBUTION
(See UFC Section 903.4,2)
SECTION 1 ~ SCOPE
Fire hydrants shall be provided in accordance with Appendix
III-B for the protection of buildings, or portions of buildings, here-
aRer constructed.
SECTION 2 ~ LOCATION
Fire hydrants shall be provided along required fire apparatus ac-
cess roads and adjacent public streets.
SECTION 3 ~ NUMBER OF FIRE HYDRANTS
The minimum number of fire hydrants available to a building shall
not be less than that listed in Table A-III-B-L The number of fire
hydrants available to a complex or subdivision shall not be less
than that determined by spacing requirements listed in Table
A-III-B-1. when applied to fire apparatus access roads and perime-
ter public streets from which fire operations could Im conducted.
SECTION 4 -- CONSIDERATION OF EXISTING FIRE
HYDRANTS
Existing fire hydrants on public streets are allowed to be consid-
ered as available. Existing fire hydrants on adjacent properties
shall not be considered available unless fire apparatus access
roads extend between properties and easements are established to
prevent obstruction of such roads.
SECTION 5 -- DISTRIBUTION OF FIRE HYDRANTS
The average spacing between fire hydrants shall not exceed that
listed in Table A-III-B-1.
EXCF.,PTION: The chief may accept a deficiency of up to 10 per-
cant where existing fire hydrants provide aJ.l or a portion of the required
fire hydrant setwice.
Regardless of the average spacing, fire hydrants shall be located
such that all points on streets and access roads adjacent to a build-
ing are within the distances listed in Table A-III~B-i.

2Where streets are provided with median dividers which can be ~rossed by firefightors pulling hose lines, or anefial streets are provided with four or more traf~e
anes and have a traffic corm of more than 30,000 '.mhicles per day, hydrant spacing shall average 500 feet (152.4. m) on each side of the street and be arranged on an
alternating basis up to a Fa'e-flow requirement of 7,000 galloos per m hate (26 495 L/min.) and 400 feet (122 m) for higher fire-flow requirements
3Where new water mains are extended along streets where hydrants are not needed for protection of srractm'es or similar fire problems, fire hydrants shall be pro-
vided at spacing not to exceed 1,000 feet (305 m) to provide for transportation hazards.
4Reduce by 50 feet (15 240 mn) for dead..~nd streets or roads.

or ortions of buildings hereafter constructed shall be in accord- m ...:.. ~ ,~ :_~. t,~.:-, ----~ - et ar "
ance with Appendix III-A. Appendix III-A does not apply to struc- ~ separate fire arias
rares other than bmlflmgs. ~ ' .......
SECTION 2 ~ DEFINITIONS
For the purpose of Appendix III-A, certain terms are defined as
follows:
FIRE AREA is the floor area, in square feet, used to determine
the required fire flow.
FIRE FLOW is the flow rate of a water supply, measured at 20
psi (137.9 kPa) residual pressure, that is available for firefighting.
SECTION 3 -- MODIFICATIONS
3.1 Decreases. Fire-flow requirements may be modified down-
ward by the chief for isolated buildings or a group of buildings in
rural areas or small communities where the development of full
fire-flow requirements is impractical.
3.2 Increases. Fire flow may be modified upward by the chief
where conditions indicate an unusual susceptibility to group fires
or conflagrations. Aa upward modification shall not be more than
twice that required for the building under consideration.
SECTION 4 -- FIRE AREA
4.1 General. The fire area shall be the total floor area of all floor
levels within the exterior walls, and under the horizontal projec-
tions of the mol of a building, except as modified in Section 4.
4.3 Type I and Type II-ER. Construction. The fire area of
buildings constructed of Type I and Type II-F.R. construction shall
be the area of the three largest successive floom.
SECTION 5 -- FIRE-FLOW REQUIREMENTS FOR
BUILDINGS
5.1 One- and Two-Family Dwellings. The minimum fire flow
and flow duration requirements for one- and two-family dwellings
having a fire area which does not exceed 3,600 square feet (344.5
m2) shall be 1,000 gallons per minute (3785.4 L~min.). Fire flow
and flow duration for dwellings having a fire area in excess of
),600 square feet (344.5 m2) shall not be less than that specified in
Table A-III-A-1.
EXCEPTION: A reduction in required fire flow of 50 percent, as
approved, Ls allowed when the budding is provided with an approved
automatic sprinkler system.
5,2 Buildings other than One- and Two-Family Dwell-
ings. The minimum fire flow and flow duration for buildings oth-
er than one- and two-family dwellings shall be as specified in
Table A-III-A-1.
EXCEPTION: A reduction in required fire flow of up to 75 per-
cent. as approved, is allowed when the building is provided with an ap-
proved automatic sprinkler system. The resulting fire flow shall not be
less than 1,500 gallons per minute (5677.5 L/min.).
