RE: Albertsons #574
City Job # 02-00099-01
Dear Mr. Puent,
The City of Springfield is reqUiring, as part of the conditions of approval for
development, that the existing trash compactor be enclosed and plumbed to sanitary
sewer. Since a yard is described as being an "unoccupied space from ground to sky" the
enclosure of the compactor reduces our overall yard measurement and as such impacts
our overall available floor area according to the current edition of the UBC.
We would request that the city accept that the Albertsons building meets the intent of
the code without including this structure as limiting the yard for the following reasons;
1. The enclosure of the compactor does not affect the overall fire resistive nature of
the building. .
a. The enclosure will be non-combustible and sprinklered. The three trash
compactor enclosure walls are all CMU. The roof will be metal and the
framing will be steel.
b. The trash compactor is self contained.
c. The enclosure is located in the center of the Albertsons building and does
not impact adjacent structures.
2. The enclosure does not affect public safety.
a. There is no exit way or pedestrian route in the proximity of the enclosure.
b. No exit path would require movement behind the enclosure.
3. The enclosure does not affect emergency access
a. Fire and rescue have access to both ends of the store and as such would
not have to move behind the enclosure.
b. The yard depth everywhere except directly behind the enclosure is
approximately 68'-0" giving more than adequate access for fire and
rescue equipment.
Although this construction situation is unique to the current building code. bothlhe new
IBC and Fire Code allow for calculations based on yards of differing depths. The
proposed method in the new codes takes into account that appendages may impact the
yard without affecting the overall firellife safety issues of the building.

The following calculations are fram Section 506 of the 2000 International Building Code.
506.2 Frantaoe Increase:
If= 100 [FIP - 0.25] W/30
where:
It = Area increase due to frontage (percent)
F = Building perimeter which fronts on a public way or open space having 20
feet open minimum width. .
P = Perimeter of entire building
W = Minimum width of public way or open space. (Occupancy Mallows W 10
exceed 30 according to 507.2, bul W/30 cannot exceed 2.0)
Ij=100 [931'11062'-0.25] 68/30=170%
*(68/30 '" 2.0 max, so 2.0 was used)
506" 1 General:
Aa =AI + [AI If/100] + [AIls /100]
where:
Aa = Allowable area per floor (square feet)
AI = Tabular area per floor in accordance with Table 503 (square feet)
It = Area increase due to frontage (percent) as calculated in accordance with
Section 506.2
Is = Area increase due to sprinkler protection (percent as calculated in
accordance with Section 506.3)
Aa = 12,500 + [(12,500 x 170)/100] + [(12,500 x 300)11 00]
= 71,250 s.f. allowable
This exceeds the 59,687 square feet proposed for the Albertsons remodel (including the
compactor enclosure at the rear of the store).
