Santamaria Concrete completed emergency roadway and drainage improvements for Caltrans along a major highway corridor in Northern California. The project involved restoring a failed drainage system, including culvert removal and replacement, grading, and site restoration under time-sensitive conditions.

The work included removal of deteriorated infrastructure, installation of a new culvert system, and regrading of the surrounding area to restore proper drainage flow and prevent roadway flooding.

Scope of work:

• Removal and disposal of existing culvert
• Installation of new culvert system
• Regrading of retention pond and drainage flowline
• Culvert cleaning and video inspection
• Placement of rock slope protection (RSP)
• Coordination of traffic control and lane closures
• Environmental compliance and material handling

Project highlights:

• Emergency response project for Caltrans
• Restoration of critical drainage infrastructure
• Work performed along active highway corridor
• Multi-phase operations under time-sensitive conditions
• Coordination with environmental requirements and inspections
• Integration of culvert replacement, grading, and erosion control

Site and engineering:

The project required restoration of a failed drainage system to ensure proper water flow and prevent roadway flooding. Grading and culvert installation were performed to meet design requirements and improve long-term drainage performance across the site.

Logistics and execution:

Due to the emergency nature of the project, work was performed under strict timelines and active traffic conditions. Coordination between crews, subcontractors, and traffic control operations was critical to maintaining safety and completing the work efficiently.

The project involved multiple phases of work, including excavation, culvert installation, and final restoration, all performed while maintaining traffic flow.

Safety:

All work was performed following Caltrans safety requirements, including traffic control measures, equipment operation protocols, and coordination in a high-traffic environment.
