o
Andy,
I may not be back in time for tomorrow's DIM meeting. Myselfand other staff members of the FMO
will be attending a seminar at the Office of State Fire Marshal in Salem. Here are the comments for
the applicable question submitted:
Question #5 asks, "Referencing the attached Schematic Site Plan, are there any other items that
need to be addressed? Are there any public infrastructure items that need to be addressed as a result
of the proposed development?"
Springfield Fire Marshals Office responds with the following:
It will depend on the type of construction and/or whether or not the building will be sprinklered. Taking
the worst case scenario of lightweight wood constructiofl (described in the 2007 Oregon Structural
Specialty Code (OSSC) and 2007 Springfield Fire Code (SFC) as Type V-B),SFC Table B 1 05.1
shows that a building of Type V-B construction at 5,177 sq. ft will require 2,000 gallons per minute
which requires a second fire hydrant.
There are three alternatives to eliminating the second fire hydrant requiremerit:
1. Install an automatic fire sprinkler system meeting the requirements of SFC section 903 and
NFPA 13. SFC section B105.3.1 allows required fire flow to be reduced up to 75 percent, but
not h~ss than 1500 gpm. Per Table C1 05.1, this allows for just one fire hydrant.
2. Use a higher construction standard, such as Type II-B (steel); III-B (m~sonry), or V-A
(lightweight wood with one-hour rated construction such as 5/8ths Type-X gypsum board
throughout).
3. Divide the building into two fire areas with a 2-hour rated fire wall meeting OSSC requirements,
with the largest portion of the building not greater than 3,600 sq. ft. This would in effect, divide
the proposed structure into two buildings and be treated as such for fire flow determination.
A second fire hydrant may still be needed depending upon the distance from the existing hydrant and
the proposed structure. Per SFC section 508.5.1, any portion of a building cannot be more than 400
feet from a fire hydrant on a fire apparatus access road as measured by an approved route around
the exterior of the building. If the distance exceeds 400 feet, an additional fire hydrant is required. Per
Exception 2 of the same secti.on, a sprinklered building's distance is increased to 600 feet.
