Protection against tampering is required. Section 6.6.4.1 of the 2002 Edition of NFPA Standard No. 13R requires a FDC "for buildings accessible by a fire department that exceed 2000 square feet or are more than a single story. The FDC would need to be within 100 feet of the fire hydrant. Hope this helps. John K.

Albert Castaneda, PE ProJf,cf Mo'agot ' 1 : alpha [11 303.432.8003 ft ] 503.45 2.8043 From: Albert Castaneda Sent: Thursday, December 21, 2006 7:59 AM To: 'eric.mcmullen @tvfr.com' Subject: Coral Commons Eric, Many months ago we talked about this project and we were conditioned to construct a fire hydrant in the middle of the frontage and sprinkler unit 11. Tualatin Valley Water has told us that we can run the fire /domestic lines out of the back of the residential meter and split the lines off in the water heater closet in the building to eliminate having separate meters for each use. There is also a backflow preventer in the building The Building Department at the City of Tigard is looking for your okay on this proposal. They are requesting an FDC for this building but I am not sure we would need it if the system is designed properly. Can you look at the attached pdf and let me know if our proposal will meet your standards. All the improvements are done on the frontage of the project including the fire hydrant. This is once again the last piece of the puzzle before we can pull the building permits for the structures. I hope you have a great holiday. Thanks again. «328- 029 - building permit.pdf» Albert Castaneda, PE " Ma"aaer to [T] 503 452 8003 1/19/2007 • FW: Coral Commons Page 3 of 3 [F] 303.452.8043 1/19/2007 "' `. • TI r LATIN VALLEY FIRE & RESCUE ) SOUTH DIVISION COMMUNITY SERVICES • OPERATIONS • FIRE PREVENTION Tualatin Valley Fire & Rescue / December 20, 2005 Gary Pagenstecher, Associate Planner City of Tigard "P 13125 SW Hall Blvd Tigard, OR 97223 Re: Coral Commons Dear Gary, Thank you for the opportunity to review the proposed site plan surrounding the above named development project.
