The Sacramento California Basin contains a dense population, two major highways, and the Sacramento International Airport. The levee system protecting the Natomas basin, just north of Sacramento, was identified as at-risk and needed fast-track evaluation to regain United States Army Corps of Engineers (USACE) certification and protect the region.
The Sacramento Area Flood Control Agency (SAFCA) started the Natomas Levee Improvement Program (NLIP) to address and remediate the levee system in accordance with USACE regulations. As SAFCA’s geotechnical consultant, Kleinfelder faced an aggressive schedule in efforts to provide engineering assessments and environmental support. Multi-year design and construction phases meant a tight schedule with constant compression as each deadline approached, so the team would need to execute with extreme accuracy and speed.
Kleinfelder developed an enterprise Geographic Information Systems (GIS) database to provide real-time access for multiple engineering teams and other contractors—allowing constant and consistent sharing of data, ensuring accuracy and on-schedule project performance. The team used automated mobile GIS GPS units to perform assessment on hundreds of levee parcels, assessing thousands of historic and recent subsurface investigations. Using GIS to manage environmental assessment reports, the team was able to attain rapid clearance of acquired properties.
Kleinfelder’s seamless integration of GIS into Phase II and remediation efforts enabled the team to reduce delays in construction, ensuring NLIP’s progress towards recertification of the levee system and the continuing safety of the Sacramento region’s valuable resources.
