Subject:. Alternate Design Request / Old Milltown / Fire Protection Yard along
South Property Line:
Dear Ms Graf,
We are requesting that the city consider an alternate design request to create a fire
protection yard along the south property line of the subject property for the
purpose of allowing openings along the south wall of the existing building that is
currently proposed for renovation.
We are proposing to establish this yard within the full area of a 15 foot
accessibility easement running east to west across the full depth of the south
adjacent lot, essentially running from, the 5t' ave property line to the west to the
property line adjoining the city alley at the easternmost line of the south property.
The properties are as you know, under the same ownership, that of GPA inc, 51
W Dayton Street, Edmonds, Wa.
We propose that providing the above described yard is equivalent to providing the
fire separation distance to a property Iine required by IBC Table 704.8. A yard is
defined as an "open space unobstructed from the ground to the sky,..." in ICB
Section 202. Fire separation distance is defined as the distance measured from the
building face to the closes interior lot line, measured at right angles from the face
of the wall" in TBC Section 702.1
We are proposing that this yard exist completely within the referenced 15 foot
easement. Per Table 704.8 (copy attached) the 15' yard in a protected building
will allow us up to 45% of the wall running along the northernmost line of the
yard to consist of exterior wall openings. Our current design proposes windows
and doors making up a total of 23% of the total wall area, well under the total
amount allowed.
The Chart below illustrates our inventory of designed openings at this wall, and
tabulates the relative percentage of exterior wall opening area. As you can see,
we have designed a total of 476 s.f. of exterior wall openings in the south wall
that is 2054 s.f. in total area.

Jeannine, I hope that this is adequate to serve as our request for consideration as an
alternate design for the creation of a fire yard at the south property of the OId Milltown
Project. We have forwarded this document to the property owner, for their use in
preparing a binding covenant to run with the land.
Thanks
