RECEIV April 17, 2002 SEP 2,6 2003 CITY OF TIGARD WFI BUILDING DIVISION 575 Andover Park Street, Suite 201 Tukwila, WA 98188 Attention: Mr. Jim Pribbenow Fax: 206 -574 -6333 Reference: 60 Ft. Model SSV Tower, Site: POR Pecan, Washington County, Oregon Dear Mr. Pribbenow: The referenced tower will be designed to meet the specified loading requirements provided to ROHN in accordance with the ANSI/TIA/EIA -222 -F Standards for an 80 mph basic wind speed and a''V2 inch radial ice load. In the event an extreme wind speed were to occur, a failure would not be expected to occur the instant the design wind speed was exceeded. All tower members would be designed to support a minimum of 1.25 times their design load without permanent deformation. It is our understanding that the design of the referenced tower requires consideration of a contained fall radius in the event a catastrophic wind speed were to result in a failure. Although the tower would not be designed to fail, stronger leg and brace members than required by analysis could be provided in the lower portion of the tower. This would result in an increased safety factor in the lower sections. This design would enable the tower to fail through a combination of bending and buckling in the upper portion of the tower should a catastrophic wind loading occur. Failure in this manner would result in a fall zone radius of 5'. Please contact us at your convenience should you have further questions concerning the safety of tower structures or . • - • s ects of tower design.

In the event an extreme wind speed were to occur, a failure would not be expected to occur the instant the design wind speed was exceeded. All tower members would be designed to support a minimum of 1.25 times their design load without permanent deformation. It is our understanding that the referenced pole requires consideration of a contained fall radius in the event a catastrophic wind speed were to result in a failure. Although this pole will not be designed to fail, stronger sections than required by analysis could be provided in the lower portion of the pole. This would result in an increased safety factor in the lower sections. In the event of a catastrophic wind, this would enable the pole to fail through a combination of bending and buckling in the upper portion of the pole folding over the lower portion, resulting in a fall zone radius of 5'.
