Statewide Impact Estimate

• $1 billion per year • $2 billion per year including local roads • Assumptions: ◦ 5-mile impact radius analysis ◦ Impact to main hwys (e.g., US or IH) not included ◦ Impact to bridges not included ◦ Impact of overweight vehicles not included ◦ Truck hauling of petroleum products in areas not

served by pipelines not included

17


Summary of Research Activities

• Field visits and data collection • Geodatabase of energy developments • Pavement impacts • Roadside impacts • Operational and safety impacts • Stakeholder meetings • Strategy recommendations

18


Driveway Permits

• Documentation issues: ◦ “P”, “SU” design vehicles not defined ◦ No guidance for larger vehicles ◦ No definition, guidance, or requirements for

“stabilized all-weather surface material” ◦ No discussion about traffic flow or TMUTCD

requirements ◦ No discussion about requirements to protect or

mitigate damage to pavement, shoulder, or roadside ◦ Casual reference to farm/ranch driveways ◦ No discussion about milestones or coordination reqs.

19


Strategy Recommendations

• Early notification and coordination • Road maintenance and repair • Roadside management • Funding

20



• Early notification and coordination: ◦ Implement and maintain the geodatabase of

energy developments in Texas. ◦ Implement interagency cooperation agreements

with other agencies. ◦ Improve communication and coordination with

energy developers. ◦ Implement additional proactive mechanisms to

learn about energy developments. ◦ Work with DPS to improve traffic safety and

protect the transportation infrastructure. 21



• Road maintenance and repair: ◦ Strengthen the use of triaxial design checks in

the current flexible pavement design method. ◦ Extend the use of nondestructive testing tools. ◦ Strengthen guidelines for cross sectional

elements on rural two-lane highways. ◦ Examine the feasibility of converting paved

roads to gravel surface roads.

22



• Roadside management: ◦ Strengthen driveway permitting requirements. ◦ Automate the driveway permitting process.

23



• Funding: ◦ Assess damages to pavement structures in

connection with energy developments. ◦ Use donation agreements with energy developers. ◦ Examine the feasibility of establishing driveway

permit fees. ◦ Review maintenance funding allocation formulas. ◦ Determine the feasibility of using energy-related

fees, taxes, and lease revenues for highway repair purposes.
