SCR 17 PM 7.61 Drainage System Replacement

Caltrans District 5 is seeking a geotechnical site investigation for the SCR 17 PM 7.61 Drainage System Replacement project located at State Route 17 in Glenwood, Santa Cruz County. The primary objective of the project is to abandon an existing culvert using slurry cement and replace it with a new reinforced concrete pipe culvert. To support this design and construction, the investigation will focus on determining soil and site conditions and assessing potential geotechnical hazards. All drilling activities are required to take place within pavement limits. The scope of work includes drilling vertical soil borings, performing in-situ soil testing via Standard Penetration Tests, collecting soil samples for laboratory classification, and developing a comprehensive subsurface soil profile. This project is classified as a forecast under NAICS code 541380 and has been granted a Class 6 categorical exemption, as it is determined to have no significant environmental impacts provided that biological resource avoidance and minimization measures are implemented. The primary point of contact for the lead agency is Lucas Marsalek.
