The Roaring Fork Transportation Authority plans to prove its authority by imposing a $10-per-year vehicle registration fee on all car owners who live within RFTA boundaries. Discussion of this new fee is among the items on the agenda for the Glenwood Springs City Council’s regular meeting, set for 6:30 p.m. Thursday. If passed, the fee would apply to residents of Glenwood Springs, Carbondale, Aspen, Pitkin County, Snowmass Village, Basalt and its adjoining part of Eagle County. Residents of unincorporated Garfield County, as well as towns west of Glenwood Springs along the Colorado River corridor, will not be affected by the fee. The fee is being introduced as a way to make up for a predicted $900,000 shortfall in RFTA revenues in 2003.A public hearing on the fee will be held by the RFTA board on Feb. 13 in El Jebel. Also on the City Council agenda:-Council will consider whether to write a letter for RFTA in support of a federal grant funding request. -Council will discuss whether to endorse members of a Transportation and Tourism Task Force.
