Updated April 16 at 12:02 p.m.: The Williamson County Commissioners approved the expansion of River Ranch County Park during its April 16 meeting. "[The county has] been given the opportunity of a lifetime to add 350 acres to what is already a beautiful park," said Precinct 2 Commissioner Cynthia Long. Earlier: River Ranch County Park, a more than 1,000-acre park currently under its first phase of development, will get a boost of 350 acres if the Williamson County commissioners agree to it April 16. The land is being sold to the county by two sellers who own a combined 500 acres of land adjacent to where the park is being built, according to court documents. The sellers will keep 150 acres, while the remaining 350 acres will be sold to the county for $12,500 per acre at a total of $4.375 million, documents say. The additional acreage will make River Ranch almost twice the size of the Southwest Williamson County Regional Park and is equivalent to adding Austin's Zilker Park to what is already being constructed. River Ranch, located on the border of Leander and Liberty Hill, broke ground in December and will include 10-12 miles of trails, camping, playgrounds, horse paths, RV parking and pavilions. The county originally purchased the land in 2008 for approximately $10.63 million using voter-approved park bonds, according to a statement from the county. The entrance road to River Ranch County Park will be located off Bagdad, west of CR 278. The first phase of the park is expected to be completed in spring 2020.
