WebIn addition, where fish passage is required, the culvert shall be designed to meet the criteria of the Active Channel Design Option, Stream Simulation Design Option or the Hydraulic Design Option for Upstream Fish Passage. The suitability of each design option is shown in Table 2. Culvert Criteria for Fish Passage 4 Revised: May 2002 WebThe PFBC and PennDOT formed a partnership to develop culvert designs for fish passage. Box culvert designs (see figures 1-4) were adopted for statewide implementation by PennDOT, and are referenced as their Design Standard BD-632M. Additional details to the box culvert design standards can be located on PennDOT’s Web
