Corpus Christi District
U.S. 181 (Harbor Bridge) Environmental Documentation and Schematic Development
Citizens’ Advisory Committee
March 7-8, 2006
Welcome
Tonight’s Agenda
• Introductions
• Project status and schedule
• New approaches to transportation project funding
• Public input process for design guidelines for new bridge
• Alternative alignments for new bridge
• Preparation for public meeting
Project Status
• Environmental Impact Statement (EIS)
• Schematic Development
• Public Involvement
EIS
• Conducted field survey of historic resources in January 2006
• Began draft park land impact evaluation (T.C. Ayers Park)
• The red and orange corridor will be studied in detail
• Ready to begin impact evaluation of proposed alignments
Schematic Development
• Continued to develop alternative alignments
• TxDOT prepared review comments on four alternatives.
• Met Jan 23 with the City of Corpus Christi, MPO, and the Port of Corpus Christi
Public Involvement
• Developed project website: www.harborbridgereplacement.com
• Planned CAC meetings
• Held stakeholder meetings
Need for New Approach to Transportation Project
Funding
Transportation Funding Issues
• Who pays?
• How much do we pay?
• Why do we have a problem with transportation funding?
• What does the future hold?
Who Pays?
• Federal government
• TxDOT
• Both
• None of the above
Who Pays?
You pay
How Much Do We Pay?
State gas tax - $0.20/gal of gas consumed
Federal gas tax - $0.184/gal of gas consumed
Is the State Gas Tax Spent Just on Highway Construction?
Federal gas tax – 90% returned to Texas
State gas tax – 60% spent on highways
Public Schools24¢ ($695.1 million)
TxDOT59¢($1.702 billion)
Other4¢($120.9 million)
DPS13¢($376 million)
How the state fuel tax is spent?
Why Do We Have a Problem with Transportation Funding?
Recent studies indicate that:
• Passenger cars used 209 gallons less in 2002 than 1970.
• Trucks used 220 gallons less in 2002 than 1970.
• However, we drive twice as many miles today than 25 years ago.
Why Do We Have a Problem with Transportation Funding?
1980 2003 % Increase• Population 14 million 22 million 57%
• Vehicles 11.7 million 18.9 million 61%
• Lanes – miles 175,000 189,000 8%

What Does the Future Hold?
• More fuel efficient vehicles
• By 2010, fuel consumption reduced another 30 to 40%
What Does the Future Hold? (cont.)
• Great for the environment
• Great for conservation
• Great for reducing our reliance on foreign oil
What Does the Future Hold? (cont.)
But not so great for transportation funding…. particularly if we continue to rely on the gas tax
What Does the Future Hold? (cont.)
SO WHAT IS THE ANSWER?
What Does the Future Hold? (cont.)
• Short term – now until about 2020
• Long term – After 2020
Long Term
Direct User Fees:
• Pilot Program currently underway by Oregon DOT
• Participants do not pay a gas tax
• Instead, participants pay a user fee based on distance traveled
• Vehicles and pumps equipped with GPS technology
Short Term
• Expansion of toll roads
• Tax on highly fuel efficient vehicles
• Increased investment from the private sector in the funding of highways
• Indexing the gas tax to inflation

Regional Context
Historic and Local Context
• What structures and buildings do you consider emblematic of the Corpus Christi Harbor Bridge Region?
• What features of the existing Corpus Christi Harbor Bridge do you think are valuable/attractive?
• Should the new Corpus Christi Harbor Bridge stand out or blend in with the surroundings?
• Which views of the new bridge are important:
Driver’s view from bridge when crossing
The view from the shoreline
Other views
• What visual elements of the new bridge would be important to you?
