WA7DUH And WB7CNV Tower Construction

Photo essay of tower project at the station of Linda WB7CNV and Steve WA7DUH. They live just outside of the Richland and West Richland city limits in Benton County. Project is to initially erect a 65 ft guyed tower, but to design it for 75 ft or higher. Benton County has an ordinance controlling "communications facilities" (BCC 11.65) which includes "communication towers and antennas." Many of the requirements are exempted for amateur radio towers and antennas not exceeding 65 ft.

bentonCoHamExemption.jpg

Benton County exemption from Benton County Code (BCC) 11.65 Communications Facilities that is really aimed at commercial installations such as TV/Radio stations or cell towers. However, this exemption did not remove the requirement for a building permit, structural analysis and original drawings with original (not copy) signature/stamp of Wash. State licensed Professional Engineer. Tower manufacturer's analysis and drawings were not acceptable (not original or Wash. licensed).

Also, county building dept. wanted to impose most of the requirements of BCC 11.65 anyway "for your and neighbor's protection". We battled several issues.
