RE: Bradley Request for Alternate Design, Plan Check #05-135
Green Roof & Bamboo Rain Screen Siding
Dear Mr. Lchn:
The City is in receipt of your supplemental letter to the request for alternate design regarding the
Bradley green roof and bamboo rain screen siding. This letter will only address the Baraboo Rain
Screen Siding alternate design request; a second letter shall be issued on the green roof alternate design
request.
After review of the information submitted, it is my determination as Building Official for the City of
Edmonds that the use of Bamboo Rain Screen Siding as an alternate method and material under the
provisions of International Residential Building Code (2003 edition) is approved with the following
conditions:
• Installation is limited to the specific Bamboo Rain Screen Siding assembly as described in your
letters to the City dated 3117106 and 5110106
• Specific details of the assembly shall be included on your plans submitted to the City
• Structural attachment of the siding shall be pursuant to the approved structural detail prepared
and stamped by Gary M. Swenson, PE #9982 Washington State Licensed Engineer, dated
572/06
• All work shall be performed in accordance with manufacturer's specifications
This letter does not constitute an endorsement of the subject product and shall not to be used in any
manner to promote Bamboo Rain Screen Siding or any portions of the assembly. As with all alternate
design requests the City suggests that property owners consult with legal advisors and their insurance
company -regarding liability associated with alternate designs.

Regarding your paragraph on establishing a collaborative process, as the City's Building Official I
must avoid creating any special relationship with any Architect, Engineer, Contractor, Homeowner,
Business Owner, or Product Representative to avoid the appearance of arbitrary or capricious decisions
in carrying out the duties of my position. The approval of the bamboo rain screen siding was made
because, as the Architect of Record, you provided satisfactory evidence, testing and proof of code
equivalency.
Lastly by adding personal comments within plan review responses you slow down the City's review
process. If you wish to personally comment on your perception of how well or poorly the City
performs pian review, how review fees are established and collected, etc. it is more appropriate to
write separate correspondence to the Department Director, Mr. Duane Bowman,
Sincerely,
61�OT

Building Official, C.B.O.
