Re: Ackerman Estates
Concept Plan Review
BRA File No. 55-04-000
Dear Eric:
We have reviewed the concept plans for the proposed Ackerman Estates development as
submitted, on December 151, 20041 b Folz, Freeman, Erickson, Inc. Followin are our
comments and/or recommendations.
Plat
1. A 60 foot Ri is recommended at the entrance of the development.
MNDOT Issues
1. In MNDOT's 1995 concept for Hi 36 the ali of Oak
Avenue passes throu Lot I and Lot 2 in Block 1. In addition it is possible
that the northern portion of Lot 3 and Lot 4, Block 1, will be affected b this
ali
.Grading and Drainage Plan
1. The house on Lot 3, Block I has a low openin elevation (LOE) of 938.5 and
a basement floor elevation (BFE) of 935.0. The existin 934 contour is shown
at the back of the structure. Is this the correct location for the 934 contour,
particularl with the pond's HWL at 933.6?
2. The second cell of the pond (the wetland area) appears to have a NWL of
932.1. This would place the NWL of the pond 13' from the house on Lot 3,
Block 1. Do y ou want the pond this close to the house? A wetland
delineation is needed. If it is a wetland, the buffer zones must be maintained
accordin to the Cit Wetland Ordinance. Is this a protected wetland? Are
there an restrictions for raisin the elevation of this wetland?
St. Paul, St. Cloud, Rochester, Willmar, MN ■ Milwaukee, Wl ■ Chica IL
Affirmative Action/E Opportunit Emplo and Emplo Owned
3. Verify the connection of the proposed 942 contour with the existing contour
on Lot 1, Block 1.
4. The pond discharges into a ditch along oakgreen Avenue. Does this water
eventually discharge into the MNDOT drainage system? If so, are there any
permits that must be obtained from MNDOT for the storm. water?
S. This development is in the jurisdiction of the Middle St. Croix Water
Management organization. The WMO should review the plans.
1. It is recommended that the water main be installed on the east side of
oakgreen Avenue and connect to the existing 12" stub located approximately
300 feet south of Highway 36.
2. A fire hydrant will be required to service the development.
3. Further review is required on the sanitary sewer and water main. To be
consistent with the comprehensive plans the City may require that the utilities
are located in oakgreen Avenue.
Bituminous Trail
1. It is recommended that bituminous radii be placed at the connection to the
existing east /west bituminous trail.
The plans submitted were concept plans for Ackerman Estates. When preliminary
grading and utilities plans are submitted a more detail review will be completed for the
development. If you have any questions or require additional information, please contact
me at (651) 604 -4788 or Dennis Postler at (651) 604 -4815.
