Easton Park, a large underdevelopment community in Southeast Austin, will host a grand opening for its newest neighborhoods, Skyline Park and Union Park, on Dec. 1. Plans for the 1,500-acre Easton Park community include approximately 6,500 homes in four neighborhoods. The community plan features an outdoor amphitheater, a community garden, 13.1 miles of hike and bike trails, and over 350 acres of green spaces, said Laura Bowman, a spokesperson for the development. A 14,000-square-foot amenity center is under construction with expected completion in 2019. It will include a club-style fitness facility, a resort pool, event space and a gaming area. About 45 acres of commercial space and 32 acres of retail space will also be included in the community. Construction on Easton Park began in spring 2015. As it stands, no firm completion date has been set, but the projected build-out will likely be 10-plus years, Bowman said.
