Plymouth Prowler in a time capsule buried in Centennial Park (formerly known as Central Park) at 6th Street and Peoria Avenue. The city plans to open it in 2048. This time, the car was encased in a specially-constructed plastic box, which was then entombed in an above-ground concrete vault. The Rotary Club added various other memorabilia to the contents of the time capsule. 21st-century developments The early 21st century saw Tulsa's economy, along with the national economy, facing another economic down-turn and a loss of jobs. However, recovery was reported beginning as early as 2004 and by 2006 the total number of jobs in Tulsa had increased to levels exceeding those prior to the downturn. Helped by relatively low housing prices, Tulsa continued to be an attractive market for business expansion. The efforts by city leaders led to the passage of the "Vision 2025" program in 2003 with the purpose of enhancing and revitalizing Tulsa's infrastructure. The keystone project of Vision 2025 was the construction of the BOK Center in downtown Tulsa. The multi-purpose arena, designed by famed architect Cesar Pelli, serves as the home for the city's minor league hockey team, as well as a venue for major concerts and conventions. Groundbreaking on the structure occurred in 2005 and the building was completed in 2009. In June 2007, the City of Tulsa formally agreed to support a plan prepared by the Indian Nations Council of Government (INCOG), an agency of Tulsa County, for River development. The plan is based on the Arkansas River Corridor Master Plan produced by city, county and local officials, and the U.S. Army Corps of Engineers in 2005. The plan calls for additional low-water dams to keep water in the river, enhancements to recreational facilities and river crossings for pedestrians, improved access to the river bank and to nearby retail/entertainment areas, aesthetic improvements to existing structures, the inclusion of additional retail and food vendors within the River Parks, additional multi-use development on the west bank of the river, and an overhaul of trails, lighting and signage. In 2014, construction began on "A Gathering Place for Tulsa," a major expansion and renovation of the Tulsa River Parks area near 31st Street and Riverside Parkway designed by landscape architect Michael Van Valkenburgh Associates. Phase I consists of 66.5 acres and is scheduled for completion in 2017. The Gathering Place is a project of the George Kaiser Family
