Travis County Commissioners Court considered a $942.3 million preliminary budget for the 2015-16 fiscal year during its Aug. 4 meeting. The proposed budget, which is scheduled for adoption Sept. 29, outlines the county’s major expenditures, such as government, the justice system, and corrections and rehabilitation costs. The county faces multiple financial challenges including housing affordability and concerns raised by citizens and elected officials about the region’s transportation system, according to budget documents. Most of the county’s funding comes from taxes, staff said during the meeting. The proposed tax rate of 42.61 cents per $100 of taxable value comprises a maintenance and operations rate of 35.62 cents per $100 of taxable valuation and a debt service tax rate of 6.98 cents. Overall, that is a decrease from the existing tax rate of 45.63 cents per $100 valuation. Home values might increase, but interim County Executive Jessica Rio said staff's tax rate recommendation is anticipated to result in a tax impact of approximately $22 on the average taxable homestead. Homestead owners who are disabled or age 65 and older will see an average annual tax increase of approximately $1, she said. A budget hearing will take place at 1:30 p.m. Aug. 6 in the Travis County courtroom, 700 Lavaca St. The preliminary budget is posted on the Travis County website.
