In addition to engineering feasibility data furnished under §363.13 of this title (relating to Engineering Feasibility Data), political subdivisions with flood control projects must provide engineering data that will clearly demonstrate the following:

1. (1) the capacity of the watershed to accommodate storm water runoff;
2. (2) the impact of the project on watershed capacity along the entire watershed and the degree to which that capacity was considered in planning the project;
3. (3) whether the project will increase or decrease the volume or rate of storm water runoff in any channel in the watershed;
4. (4) if the project would increase the volume or rate of storm water runoff, that adequate consideration was given to alternative approaches that would decrease or hold constant the volume or rate of storm water runoff;
5. (5) the project will not significantly increase the peak water surface elevation of any portion of any stream within the watershed or within any downstream watershed. Potential loss of life and property will be considered in evaluating significance of peak water surface elevation impacts for flood control projects;
6. (6) the relationship of the project to any floodplain management plan for the watershed; and
7. (7) adequate consideration was given to the effects of the project with regard to erosion and sediment control.
