Travis County commissioners voted Nov. 13 to revise budgets while maintaining original schedules for the county’s 2017 bond and critical safety projects in light of rainfall intensity data published by the National Oceanic and Atmospheric Administration on Sept. 27. The decision will add $22,170,229—a 7.9 percent increase—to the total cost of the projects. This is a revised calculation from the $31 million estimate provided in October. “We have gone through those numbers project by project and have whittled that number down to about $22 million," said David Greear, Travis County assistant public works director. Bond projects under Proposition A—road, bridge and drainage projects—account for $12,449,918, or 13 percent, of the increased cost. Critical safety projects—those that do not require voter approval—will increase by a total of $9,720,311, up 10 percent from the original cost estimate. There are no anticipated cost increases to bond projects approved under Proposition B—park and land conservation projects—because they are not drainage-related. The county's planning and budget office will present options for supplying an additional $22 million in December, Travis County Budget Director Travis Gatlin said. “It is a cost increase," Travis County Judge Sarah Eckhardt said. "It’s outside of our control, but it is within our grasp, within our means [to fund].”
