	The plan sheet for stream crossing projects is used to show the alignment of the stream in reference to the alignment of the roadway. The information provided on this drawing is used in the hydraulic analysis for the project vicinity during flood events. The accuracy of the hydraulic analysis, the hydraulic performance of the new bridge structure during a flood event, and the determination of possible flooding effects on properties in the vicinity are all highly dependent upon the detail and accuracy provided in this drawing.

	The three lines of ground profiles plus the proposed profile grade provide critical information used in the layout of structures. The profiles aid in determining the length of structure, allowable substructure location, span lengths, superstructure type, superstructure depth and verification of the proposed profile grade. This information is used in conjunction with the freeboard or minimum vertical clearance requirements.
