Based on inspections, USACE ranked this portion of the levee as "Minimally Acceptable" with a recommendation to address the burrowing animal damage to the levee. Despite implementation of a long-term burrowing animal abatement program, animal burrows continue to persist throughout the levee embankment's landside and riverside slopes along the entire length of the creek. If left unabated, the current condition may induce levee failure by sloughing, slumping, and/or piping through the levee during high storm events. To maintain this certified levee within the "Acceptable" ranking from the USACE inspection, construction of this Project is proposed this year.
This Project will: A) repair damage to the levees due to burrowing animals along the most critical areas where a substantial number of holes have emerged within the levees immediately downstream of SR 237; B) reduce...
