Austin officials announced Tuesday that the city is among five across the nation awarded technical assistance to “green” their capitals. The U.S. Environmental Protection Agency has said it will provide technical assistance to develop infrastructure that contributes to greener, more vibrant neighborhoods. City and federal leaders will share how the technical assistance will be applied in Austin at a City Hall news conference today. Attendees will include Mayor Lee Leffingwell, EPA Region 6 Administrator Ron Curry, Waterfront Planning Advisory Board Chairman Brooke Bailey and other representatives from the City of Austin. The conference will begin at 11 a.m. in the City Hall atrium.
