Effect of the implementation of the fluvial performance standard on maintenance of bridges and culverts

The objective of this project was to determine what factors influence maintenance cost of Oregon Department of Transportation (ODOT) stream-crossing structures. Data acquired for the project included structure characteristics, stream characteristics, peak flows, and 1996-2010 maintenance costs for five maintenance activities. Nine factors were selected to investigate: active channel width, ratio of valley width to active channel width, number of hardwoods, number of conifers, ratio of bridge length to active channel width, ratio of longest bridge span to active channel width, and the ratio of peak flow to average flow both the year of maintenance and the year prior to maintenance. Possible relationships were investigated through the use of scatter-plots and bar-charts., Introduction -- Methods -- Results and discussion -- Conclusions -- References -- Appendix A: Repair and replacement rip rap (activity 343) costs -- Appendix B: Drift removal (activity 347) costs -- Appendix C: Total maintenance costs -- Appendix D: Bridge characteristics -- Appendix E: Stream characteristics -- Appendix F: Peak flow/average flow ratios., This archived document is maintained by the Oregon State Library as part of the Oregon Documents Depository Program.
