dewatering methods prior to beginning dewatering."

the proposed discharge will not cause erosion issues. Reinforced erosion control matting
may be required.
A stable emergency overflow (EOF) for the stormwater pond shall be provided. The
EOF could consist of riprap and geotextile fabric or a turf reinforcement mat (a
permanent erosion control blanket). A typical detail shall be included in the plan. The
overland route from the EOF to Lake Minnewashta shall be shown on the plans and shall
be encumbered by a drainage and utility easement.
m. Erosion control blanket shall be installed on all slopes greater than or equal to 3:1. All
exposed soil areas shall have temporary erosion protection or permanent cover year
round, according to the following table of slopes and time frames:
Type of Slone
Time
Steeper than 3:1

14 days
Flatter than 10:1
21 days
(Maximum time an area can
remain open when the area
is not actively being worked.)
n. These areas include constructed storm water management pond side slopes, and any
exposed soil areas with a positive slope to a storm water conveyance system, such as a

(e.g., Minnesota Pollution Control Agency, Minnesota Department of Natural Resources
(for dewatering)) and comply with their conditions of approval.

full disclosure about the Minnesota Landscape Arboretum location, use of electric fence,
research operations, and agricultural operations including the spraying of trees.
