NCI performed the planning and engineering studies to develop alternatives for replacing a destroyed outlet structure and a damaged sewage pipeline, refilling and regrading the scoured creed bed, and repairing the eroded slope banks. The outlet structure, sewage pipeline, and creek bed and banks were damaged during the 1997-1998 El Nino season. A subsequent revegetation plan and monitoring program was also proposed to restore the biodiversity of the regraded creek bed and bank located within 300 feet upstream of the outlet structure. NCI assisted the City in applying the permits from various State and Federal regulatory agencies. NCI performed all the engineering, and prepared the plans, specifications, construction documents and cost estimate for this project. Construction support services were also provided.
