DOWNTOWN LOS ANGELES — Downtown's expansive continues to open in phases this week, with the debut of the third block (dubbed the Community Terrace) slated for Tuesday morning.

At 9 a.m. tomorrow, the L.A. County Board of Supervisors and the L.A. Grand Avenue Authority will host an opening ceremony in the park's Flag Garden. The event will include a September 11 remembrance dedication, a flag raising by military veterans and a Sheriff and Fire Department honor guard processional.

This newest portion of the park will span from Hill to Broadway. The final stretch of the park, bordered by Broadway and Spring, is expected to open on October 6. It will consist mostly of an and appears to be the largest section of grass in the park.

The first two blocks of the 12-acre Grand Park opened at the end of July, with a colorful, costumed celebration of music and choreographed dancing that highlighted the renovated Arthur J. William Memorial Fountain.

The completed blocks between Grand Avenue and Hill Street include bright pink benches, drought-tolerant plants, hundreds of new trees and a small stage. The county park was paid for without taxpayer money, and most of its $56 million construction budget was funded by the private entity, Related Companies.

Walter Lutz of Highland Park was one of the approximately 7,000 Angelenos to attend the park's opening festivities this summer. He said Downtown used to be a "ghost town" after business hours, but in recent years there are more people out walking and bars and restaurants are bustling.

"I don't think this one thing is going to revitalize Downtown, but I think it's an important piece..." Lutz told Blogdowntown in July.
