Officials of the city and Westfield Corp. officially opened the new Horton Plaza Park in downtown San Diego, debuting with a public ceremony following a $17 million redevelopment of the 1.4-acre property next-door to the Westfield Horton Plaza mall.

The 53,000-square-foot urban plaza, at Fourth Avenue and Broadway, will host special events and community activities programmed year-round by Westfield.

The venue now has its own amphitheater, a restored historic fountain, an interactive pop-jet fountain, and eight 23-foot-tall sculptures with color-changing features. An area called Plaza Play will have oversized games, and Park Unplugged will host a series of live entertainment events, including music, dance, comedy and other performances.

Food and beverage pavilions will be operated by vendors including Starbucks and Sloan’s Ice Cream, and there is a trellised patio with seating at each pavilion.

Construction on the project, overseen by the city and Westfield in a partnership arrangement, has been ongoing over the past four years. Westfield will be responsible for activating the park starting with 75 initial events, eventually increasing to more than 200 events annually.

Officials said the park has capacity for 5,000 people and will be available for public and private functions, including recreational, cultural, educational and promotional events. More information is at hortonplazapark.com.
