Williamson County has had two successful voter approved bond elections. In 2000, county voters passed a $350 million road bond package and $25 million park bond package. This road bond was the first step toward implementing a multi-corridor transportation plan adopted by the Commissioners Court in 1999. The park bond program secured 1,321 acres of parks and open space in the county, including the creation of the 800-acre Southwest Williamson County Regional Park on C.R. 175 and 300-acre Berry Springs Park and Preserve on C.R. 152.
In 2006, voters passed a $228 million road bond package and a $22 million park bond package. The road bond program in total has completed 111 projects adding 175 new capacity lane miles with a total of nearly 300 lane miles construction. The park bond allowed for the acquisition of two new park properties – River Ranch County Park, 1,000 acres located between Leander and Liberty Hill off C.R. 282 and Blackland Heritage County Park, 348 acres located on SH 29 two miles east of Jonah, Texas.
