Information required for Culvert Study Reports
Culvert Study Report form (DOC 27K)
Culvert inspection and sampling is normally performed during winter when stream flows are greater. Lead-time for field inspection, sampling, lab testing and final recommendation must be taken into account when requesting a culvert study report.
Contact (707) 445-6355
Required Information:
- Route, post mile, and E.A. for each culvert
- The type of project this report is requested for, i.e. culvert rehab, CAPM, 3R, new construction, etc.
- The phase that this project is in, as well as the stage; whether it is a Preliminary Study, PSSR or Project Report. Please provide the PS&E date and Circulation date.
- Indicate if this project incorporates any other projects in design, if it supercedes any other project, or if it adjoins other projects. Also indicate future plans for improvements (i.e. widening).
- Please provide a list of culverts that have been Field Reviewed by the Design Branch. Include post mile, description, and indicate if cleaning is required.
