Abstract: As authorized by Section 1202 of the Water Infrastructure Improvements for the Nation Act (WIIN Act of 2016, Public Law 114-322), the study is an integrated feasibility report and environmental assessment completed by the U.S. Army Corps of Engineers (USACE), Tulsa District (SWT). USACE constructed the Tulsa and West Tulsa (TWT) levee system in the mid1940s as authorized in the 1941 Flood Control Act to protect residential and industrial property from frequent flooding along the Arkansas River and associated tributaries in the City of Tulsa, Oklahoma and the City of Sand Springs (an incorporated area adjacent to the City of Tulsa). In 1945, USACE completed Levees A, B, and C that consist of 20 miles of earthen levees along the left and right bank of the Arkansas River. The levee system extends from Sand Springs downstream along the Arkansas River to Tulsa. Upstream, there are a series of USACE flood control dams. Keystone Dam is about 8 miles above Tulsa, and flood discharges from Keystone have direct and substantial impacts to the levee system. Kaw Dam is 100 miles upstream of Keystone. The problem addressed in this study is flood risk to people and property in communities behind the levee system, which could fail due to overtopping and uncontrolled under-seepage and through seepage.1 As the levees continue to degrade during flood events, their ability to operate as originally designed diminishes. If no action is taken, under and through seepage problems will worsen and threaten the integrity of the levees, and further degrade pump stations and related works resulting in interior flooding that would have major impacts to people residing behind the levees in terms of potential injury and life loss, and to regional commerce and infrastructure. Given the problem, there is ample opportunity to identify a long-term cost effective and environmentally sustainable solution to reduce risks to life safety and property due to levee breach and non-breach flooding.
