River Park Under Construction at 4700 East Riverside Drive

Construction began September 24, 2025, when AEG Presents broke ground on the music venue that anchors the first phase of River Park, a mixed-use development at 4700 East Riverside Drive. The first phase includes 370 apartments, more than 400,000 square feet of office, 12,000 square feet of retail, and a 2-acre park on a 15-acre block.

The 109-acre site is bounded by Roy G. Guerrero Colorado River Metro Park, East Riverside Drive, Pleasant Valley Road, and Country Club Creek. Total cost is estimated at $4 billion, phased over 10 to 20 years. The project was known as 4700 Riverside before it was rebranded River Park. Hines is teaming with Presidium and Partners Group on the office portion.

The first phase centers on United Heritage Hall, a 4,000-capacity, roughly 65,000-square-foot indoor music venue developed with AEG Presents, Westfield, and Partners Group. It broke ground with the project and is slated to open in early 2027. The broader plan calls for more than 30 acres of public parkland and open space, trails connecting to Roy G. Guerrero park, a greenway along Country Club Creek, and retail and restaurants. Presidium has said the project will include long-term affordable housing but has not specified how many first-phase units will be income-restricted, who would qualify, or when those homes would become available.

The site sits near Oracle's headquarters and the planned Project Connect Blue Line station. The design is transit-oriented, with bike lanes and pedestrian walkways throughout.
