Plans for a $1.5-billion redevelopment of the Westfield Promenade shopping mall in Warner Center took another significant step forward last week, with the publication of a final environmental impact report for the project.

Unibail-Rodamco-Westfield SE, the French real estate firm which now owns the 35-acre property at 6100 N. Topanga Canyon Boulevard, intends to raze the largely empty mall and its surrounding parking lot to make way for the construction of a multi-phase mixed-use complex consisting of:

1,432 residential units;

approximately 244,000 square feet of shops and restaurants;

approximately 629,000 square feet of office space;

up to 572 hotel rooms, and

a 320,000-square-foot, 15,000-seat sports and entertainment center.

The proposed development would feature an array of low-rise and high-rise buildings, including a 28-story tower which would be the tallest structure in Warner Center. The sprawling project site would be bisected by new streets and pedestrian corridors, accounting for 5.6 acres of publicly accessible open space. This total includes a proposed central green area near the heart of the property.

Construction is anticipated to occur in four phases, starting with the northeast quadrant of the property in 2021, followed by the northwest quadrant in 2024, the southwest quadrant in 2027, and finishing with the southeast quadrant in 2033.

A full buildout of the Promenade 2035 project would add approximately 3,714 residents and 3,048 jobs to Warner Center.

Unibail-Rodamco-Westfield SE, which was formed last year through the merge of Unibail-Rodamco SE and the Westfield Corporation, is not the only developer proposing a multi-phase project for Warner Center. Less than a mile east at the corner of Burbank Boulevard and De Soto Avenue, Adler Realty Investments has announced plans to redevelop a 24-acre office park with a similar $1-billion development.
