	When an existing structure that is to be replaced has provided adequate performance, a [[131.1 Design Exception Process\|design exception]] to ~~match~~ the hydraulic performance of the existing structure is ~~necessary and~~ encouraged. Thorough documentation of the adequate historical performance is included with the ~~Design Exception~~.		When an existing structure that is to be replaced has provided adequate hydraulic performance, a [[131.1 Design Exception Process\|design exception]] to use the hydraulic performance of the existing structure as the hydraulic performance criteria for the new structure is encouraged. Thorough documentation of the adequate historical performance shall be included with the design exception.

			Meeting [[750.7 Non-Hydraulic Considerations#750.7.3 Environmental Requirements\|environmental requirements]] for new culverts is still required.
