(Design Point)

*Basln parameters not developed due to lact of any polnt-of-~oncentratlon for either local or contributory
storm water runoff.

**Basln parameters other than Sub-basin Area represent composite sub-basins tributary to the design polnt-
of-concentration.

Note: Sub-basins A2a and A2b were combined for the determination of peak flows at Design Point A2b. Basin
Parameters for the combined Sub-basin are shown on page B-2 of Appendix B.
