Residents of Smiley Court, a family housing facility at the University of Colorado at Boulder, are being offered temporary relocation to other on-campus housing while problems with some gas lines are repaired, according to Deb Coffin, director of housing at CU-Boulder. In order to repair inferior gas-line welds, gas service was turned off Thursday, resulting in the loss of hot water and heat for residents. Relocation is not mandatory, but is offered as an option for those inconvenienced by the gas shut-off. The apartments are safe for habitation, Coffin said.
