By the Numbers
The Green Line
By Katherine Gregor, Fri., Sept. 12, 2008
Scope
162; Entire mileage of existing Cap Metro-owned rail line, Giddings-Llano
28; Miles of proposed Green Line system, Austin-Elgin
8; Passenger stations proposed (Downtown Austin, Plaza Saltillo, two Park & Rides in East Austin, SH 130, Manor, midway Park & Ride, Downtown Elgin)
30-35 minutes; Travel time: Elgin to Austin Convention Center
20 minutes; Initial time between trains, peak periods
5; Initial number of diesel-fueled passenger cars running
Riders
7,000 to 12,000; Base forecast: 2,030 daily weekday riders (1.8 million to 3.1 million annually)
20% to 40%; Potential ridership increase if transit-oriented development along route is fully implemented (and as gas prices rise); additional ridership is anticipated from reverse commutes, weekend use, and special events
450; Passengers per hour in each direction, initial capacity
2,400; Passengers per hour in each direction, long-term capacity
Costs
$161 million to $192 million; Start-up system capital costs
$10 million to $15 million; Annual operating and maintenance costs
64 cents to $1.20; Annualized cost per passenger mile
$8.82 to $16.48; Annualized capital cost per passenger trip
$6.50; 2030 rider fare projected, one-way (21% to 35% of annual operating and maintenance cost)
Financing
10; Partners with strong potential to co-fund the project (Cap Metro; cities of Austin, Manor, Elgin; counties of Travis, Bastrop; Central Texas Regional Mobility Authority; Texas Department of Transportation; Federal Transit Administration; private sector)
21; Potential revenue sources: fare-box revenue, sales tax, property tax, assessments, user fees, parking revenues, federal funds, state funds, general obligation bonds, hotel/motel tax, electrical sales, development revenue and franchises, capital improvement projects budgets (water/wastewater, roadways, airport), other fees, private-sector contributions
Value-Capture
$398 million; Increase in property values (tax base) projected along rail line by 2030 (16% higher than without rail), Austin to Manor portion only
50%; Increase in values of development projects near DART Rail stations in Dallas, from 2005 to 2007
70%; Percentage of system construction costs that potentially could be funded with tax increment financing (Austin to Manor only)
80 acres; Size of Elgin tract purchased for transit-oriented development
$664 million; Increase in tax base for 80-acre site, for TOD vs. conventional development
$2.9 million; Increase in regional income, for each 1% of travel shifted from auto to transit
Environmental/Quality of Life/Safety
113 million to 194 million; Decrease in annual vehicle miles traveled, by 2030, attributable to Green Line
95%; Decrease in carbon-monoxide air pollution, per passenger mile, transit vs. auto
45%; Decrease in CO2 emissions, per passenger mile, transit vs. auto
46%; Percent of U.S. vehicles that leak hazardous fluids, causing water pollution
40%; Increased rate of traffic fatalities in cities with bus-only transit vs. large rail transit cities (four additional deaths/100,000 people)
Timeline
3 to 4 years; Time needed to design and build the system, from project authorization
2014; Year the first commuter trains could run, assuming: 2009 project approval, one to two years to work out partnerships and funding/financing, four years to build system (waiting on federal funding could add another two to four years)

All numbers will be refined by further research, analysis, cost/ridership modeling, and engineering studies. The full 38-page report with appendices should be posted online soon at www.capmetro.org.
