L575 Levee Restoration Information - UPDATED 6/8/19

Background: The L-575 Benton-Washington-McKissock-Buchanan-Atchison-Hamburg Levee System experienced significant damage during the 2019 Flood Event. This led to seven (7) breaches, along with substantial other damages, occurring throughout the Levee System.
Current Action: Two priority breaches that are impacting the I-29 corridor have been identified for initial repairs. These two construction contracts were awarded on 14 and 19 Apr 2019. The OSRT is also working an overall plan for rehabilitating the levee system. 
Next Steps:
  1. Provide an interim level of flood risk reduction at both initial breach repair locations.
  2. Conduct physical damage assessment when water levels recede and the levees are accessible
  3. Design and construct levee rehabilitation to authorized level of flood risk management.

When Lives Depend on You
Irwin Army Community Hospital
Feb. 6, 2024 | 7:20
Fog clings to the battlefield as CPL Ivan Gaona, an Army Animal Care Specialist, steps onto the training ground. This isn't any ordinary day - it's the Tri-Command Best Leader Competition, and the pressure is on. But CPL Gaona isn't fazed.
Thrown into the chaos of a simulated combat zone, Gaona isn't alone. He commands a team of Soldiers, each depending on his leadership skill and composure. With adrenaline pumping, they clear a smoke-filled room, every movement precise. His heart rate barely spikes when he encounters a fallen Soldier, leg mangled and moaning. Tourniquet applied, he drags him to safety under simulated enemy fire.
But the real test awaits. The "Mystery Lane" will throw a curveball at every competitor, a challenge none of them could possibly prepare for. Yet, when CPL Gaona sees the scenario unfold, a smile breaks through the sweat and grime.
Every instinct honed through years of caring for creatures big and small kicks in. This isn't just about winning a competition; it's about the unwavering spirit of a leader, the Soldier who steps up when it matters most, no matter the challenge.
