RE: EARL HOHLEN PROPERTY DRAINAGE ISSUES
Dear Mr. Klaers:
As requested by the City Council, please consider this correspondence to be a follow-up on
the drainage issues on the Earl Hohlen property. As you are aware, we are proceeding with
the installation of a 72-inch diameter pipe under the highway intersections of TH 10/1011
169. We are also proceeding with the installation of a 42-inch diameter pipe north of County
Road 12 which will collect water from the area of County Road 13 and 5th Street and the
Schultz/Deschene property and convey it to County Ditch 10. The missing piece in this
segment of storm sewer obviously is between County Road 12 and the railroad crossing at
the south end of the Earl Hohlen property.
At this time, we are working with the Eric Pederson Group relative to the development of
a commercial shopping area on F..(l~i's property. We have communicated to them the City's
plans for overall storm drainage facilities and, specifically, the improvements we are
currently undertaking. We expect that their submittal for the development concept of Earl's
property will not only incorporate their specific storm drainage needs, but also the larger
trunk needs of the City. As this development proceeds, we will need to begin constructing
a pond just upstream of the railroad crossing. The Comprehensive Storm Drainage Plan
ultimately calls for a 11O-acre pond in this area. We will also need to increase the size of
the culvert under the railroad to 72 inches. Attached is a copy of an exhibit from the
Comprehensive Storm Drainage Plan for this particular area which shows these installations.
If for some reason the development of Earl's property does not proceed, at that time the City
will need to deal with the issue of a larger culvert (72 inch) under the railroad crossing. We
believe that at this time we should allow the proposed development of Elk River Crossing
to proceed and hopefully incorporate the storm drainage improvements with the development
of this site.

Hopefully, this information will answer the City Council's questions relative to the storm
drainage improvement in this area. If you have further questions or would like additional
information, please call.
Sincerely,
MSA, CONSULTING ENGINEERS
