An approved hydraulic report may need to be revised because of design changes during the design phase or construction phase of the project. There are two ways to submit a change:
1. Revision: A revision is a correction to the existing report because of either an error or omitted design documentation. The PEO shall submit the revision along with a new title page that is stamped and signed by the PE with the same date as the revision or later.
2. Supplement: A supplement is a change that was not part of the original scope of work. The same approval process is required as with the original report; however, the supplement shall be a standalone document that references the original report. The supplement shall indicate what the existing design was and how the existing design has changed as well as describe why the change was necessary.
Either type of change shall be included in a submittal package with the changes clearly documented as well as supporting analysis and data including any revised plans, calculations, and other updates, as warranted, to support the change. The package shall be submitted to the concurring authority following the guidance in Section 1-3.3 and as shown on .
