This project remediated issues affecting operation of the Nubbin Slough Stormwater Treatment Area.
Stormwater Treatment Area Rehabilitation
The scope included correcting deficiencies in two perimeter levees by raising the berms; excavating undesirable material from the ditches and placing geotextile fabric and filter sand; installing culverts; and sodding the side slopes.
Access and Monitoring Improvements
ETS removed old stilling wells and installed new stilling wells. The project also included construction of an access ramp and staging area to provide District parking and access to the levees from the south, along with permanent fencing.
