The Tucson City Council has approved a $990,000 settlement to Union Pacific Railroad after a city employee improperly marked a waterline location.
It resolves a lawsuit Union Pacific filed after the 2010 waterline break that dumped nearly 11 million gallons of water into its rail yard in Tucson.
The Arizona Daily Star says a city worker blue-staked a waterline at the Union Pacific yard in May 2010 in preparation for some excavation work the company was planning.
The employee marked the wrong spot, resulting in a Union Pacific contractor hitting a 30-inch water main a few days later.
Union Pacific sued Tucson for about $1.3 million.
City Attorney Mike Rankin says the settlement paperwork should be finalized within two weeks and the money will come from Tucson's self-insurance fund.
