a. The diaphragm assembly design requirements are also dependent upon the aspect ratio. <br /> In the calculations you show your ratio to be less than 4:1.According to Table 4.2.4 of <br /> the NDS SDPWS,the appropriate diaphragm sheathing type options for a diaphragm of <br /> this aspect ratio include: 1. Wood structural panel, blocked, or 2. Double-layer diagonal <br /> lumber sheathing. <br /> SDA: Revised drawings and calculations to be issued to provide a diagonal bracing system for <br /> transferring lateral loads into house structure. <br /> 2. On the second-floor plan on sheet SC5 I am unable to determine how the new and existing <br /> decks converge. Please clarify how the decks are to interface at their shared sides. <br /> SDA: Seismic gap to be specified on the revised S-Sheets. <br /> 3. The reports acknowledged that the decks were constructed in a controlled space with no <br /> exposure to wet conditions. In what manner does the design consider the effect of weather <br /> conditions on this deck? <br /> SDA: Revised S-sheets will use an alterative method for transferring lateral loads. Alternative <br /> method considers wet service use (MC>19%)for member and connection designs. <br /> Thank you again for the information. Please feel free to reply to this email as your response to my <br /> questions and by resubmitting drawings as needed. <br /> Regards, <br /> — Ben Monk, P.E. <br /> Building Plans Examiner I Permit Services <br /> 425.257.8810 1 3200 Cedar Street, 2nd Floor, Everett, WA 98201 <br /> EVERETT Phone Hours: M/W/Th: 8:30 a.m.—12 p.m & 1 p.m.—3 p.m. <br /> everettwa.gov/permits I onlinepermits.everettwa.gov I Facebook Twitter <br /> Category 2: For official use only/disclosure permissible by law. <br /> From:Jasper JB.

The findings in this report are used to justify the deck <br /> diaphragm for this project. <br />
