MEMORANDUM
Peter Smith, City Attorney
Ken Griffin, P.E., Assistant City Manager/City Engineer ~-~
Drainage Participation, Quill .Property (Freeport North Lot 3C)
Date: July 10, 1996
This memo is written as a follow up to our meeting on July 5, 1996. Generally, the work
involves installing a parallel drainage system associated with the Quill development. The
existing system installed in the mid 80's is inadequate to convey the 100 year runoff for the
developed property. Our requirement is that the storm drainage systems either have to convey
the 100 year runoff or the developer of the property has to provide some sort of detention or
retention or they have to upsize the system. In this case, the developer has indicated that he is
willing to put in a parallel system, but because he has only two-thirds of the drainage area, he
would like to have the developer north of him or the City pick up one-third of the cost. The
system will be approximately 480 feet on the Quill site and approximately 300 or 400 feet
offsite. The system will convey all the storm runoff from the Quill side. This will free up the
existing system to convey the runoff when the land north of Quill develops.
Attached to this memo is an exhibit showing the existing and proposed systems. The proposed
design will be part of the Quill Corporation Plans by Michael Peeples and the existing system
is included in the FreePort North Plans as designed in 1984 by Hawrylak and Associates.
As we discussed, I am interested in determining the legal steps to go through to set up some sort
of a drainage prorata for the City to participate at this time and recoup our cost in the future.
If you should ,have any additional questions, please feel free to contact me at your convenience.
