To whom it concerns:
This letter serves as acceptance of conditions to design review approval set forth by the City of Tigard
Community Director's Desginee on June 16th, 2012. Conditions of acceptance have been described as
submitting or deferring permit for signage, and demonstrating 60%or higher visual transmittance (VT)of all
new glazing on the ground floor level facing Main St.
We have chosen to defer the signage permit to a later date,and I have attached with this document a
manufacturer's chart that demonstrates coherence to the condition described above. The area highlighted
in yellow shows conformance to a 60%or higher VT for the products we intend to utilize in glazing on this
project.
Please contact me directly if there are any further questions,comments,or decisions to report.
Sincerely,
opipp

Dan,this looks good to me for meeting the condition of approval. Can we incorporate this into the building specs for the
windows?
Thanks,Albert.

Hi Greg,
I checked on this, and the condition of approval requires the new ground floor windows meet the.6 visual transmittance
standard.
Hopefully,there is a lower E product out there that meets the standard (at a price that makes sense). Windows are
eligible for the facade improvement grant.
Thanks,
Sean

Sean, we are not altering the windows that front the street, does this also apply to the
new windows that are setback from the street 50 ft? Thanks! Greg.

Hi Greg,
Just to clarify,the .6 visual transmittance only applies to ground floor street facing windows. Rear and upper floor
windows don't need to meet the standard. _
Albert will be working with you to get the final sign off.
Let me know if you have any other questions.
Thanks,

Sean and Albert, I am trying to hunt down some information on the planning design
review for this project. Apparently John Floyd is out of town currently. We have passed
building permit review, but need the final sign off on the design review. I received a
conditional approval on this some time ago, but did not realize that this would keep up
2
the release of building permit. I am happy to comply with the design review conditions,
though i do have questions about one: .6 or higher visual transmittance on
glazing. This would require clear glazing that excludes low-E possibilities, and therefore
- makes the building far less efficient. I want to make sure that this is desirable to the
city before committing. Please give me a call whenever you have a chance, I've
attached a copy of the conditional approval letter. Thanks. Greg.
