Re: Eagle Hardware
Memo to File:
I have reviewed the Eagle Hardware request for alternates, (Copy Attached), and I
have forwarded the comments as attached.
In reviewing their request, I talked at length with the Commercial Plans Examiner
with the City of Mt. Vernon, WA. I went through the alternates requested by Eagle
for the store here, receiving the following information from him.
The store in Mt. Vernon is the same style and size at the request for Tigard. The City
of Mt. Vernon advises that all requirements from the code, Smoke Vents, Curtains,
sprinkler requirements were installed as required by code.
The sprinkler omission in the shaded area was approved in the shaded area, based on
the retractabilty of the screen and the material used.
