County Ditch No.9 Crossings Plan Review
Albertville, Minnesota
SEH No. A-ALBEVOI12.00 14
I reviewed the ditch crossing plan and associated drainage calculations. My comments are as
follows:
1. The culverts should be designed for the 100-year frequency flood condition with a
corresponding peak discharge rate of 205 cfs, without overtopping any of the roadways.
Thus, the storm sewer culverts should be upsized from 54" to 60" equivalent round diameter
(or larger) at the Kaiser Avenue, 51st Street, and Kagan Avenue County Ditch No.9
Crossings. See the attached revised nomographs for each street.
