Pittsburgh City Council is considering a packet of legislation that would force business owners to pay a prevailing wage and make their buildings and vehicles environmentally friendly if they receive public subsidies to build them.

Unions have lobbied city council to pass such rules.

Council president Doug Shield introduced a bill requiring janitors, kitchen workers and grocery employees to be paid a prevailing wage of $11 an hour, instead of the $7.25, in any business built with public funds. The bill could affect a Target store and a grocery store planned for two of the city's poorer neighborhoods.

Councilman Bill Peduto said he will introduce a similar bill requiring businesses that get public money to use "green" technologies later this week.

The mayor said he has moved out of that house.Erin Ravenstahl released a statement to the station saying, "I will always be Luke's friend and continue to share with him our love of our son Cooper."
