2011 SPRING FLOODS
As of February 18, 2011, the National Weather Service (NWS) has predicted significant flooding
for the upper Mississippi River basin. The next forecast by the NWS is expected in early March
and should provide more accurate information. In the city of Cottage Grove, River Acres and
Grey Cloud Island are two areas of concern should flood stages reach above six to seven feet.
A neighborhood /community meeting has been scheduled for Tuesday, March 8`" at 7:00 p.m. in
the City Council Chambers. Letters have been sent to 25 residents of River Acres and 15
residents of Grey Cloud Island whom could potentially be affected by the flooding. The intent of
the meeting is to inform residents on potential flooding impacts, effect on utilities and public
services.
Emergency services (police, fire and ems) would continue to affected areas though response
times will be impacted. More specifically fire services on Grey Cloud Island could be affected
because there would be limited apparatus available should the roadways be closed. Police
response would involve leaving a squad on the island and personnel responding via boat.
Emergency Medical Services would be arranged through local helicopter service and landing
zones have been identified on the island.
In regards to River Acres, emergency services would continue. Public Works intends on
delivering sand and bags for homeowners in affected areas. If needed, police would provide
security and controlled access to affected areas.
It is imperative that the Council come to consensus on the level of response of city services in
order that equipment, materials and personnel are procured in advance of any potential flooding
because resources will be in high demand all across the state.

Z AII elevations in vertical datum NAVD88
3 Flood Stage and River Elevation in Cottage Grove are interpolated values between the Flood Stages and
River Elevations identified in St. Paul and Hastings. The interpolated values reflect a location on the
Mississippi River at the River Acres development, River Elevations at other locations in Cottage Grove may be
different.
"River Stage categories "Moderate Flood Stage" and "Major Flood Stage" were determined by Cottage Grove
and are based on the following physical landmarks:
- Lowest home opening in River Acres (8327 River Acres Road) = 3.7 feet above Flood Stage
- Grey Cloud Island Drive (Causeway) = 6.2 feet above Flood Stage
- Grey Cloud Island Trail Bridge = 7.0 feet above Flood Stage
- Grey Cloud Island Trail = 10.7 feet above Flood Stage
