Mr . Hempel of your Engineering staff estimates the cost for City Project No. 89-11 at $1,515 .00. The Managers have authorized a 50% cost sharing in an I amount not to exceed $757 .50, as a contribution toward the completion of the Project, upon condition that the City of Chanhassen agrees that it will assume the obligation for ' maintenance on a regular basis, so as to prevent future reoccurrence of the problem which necessitates removal of excess material and a restoration of the shoreline of Lake Riley. Assuming the City of Chanhassen is in agreement, the District I will reimburse the City upon receipt of a certification from the City Engineer that restoration of the upstream sedimentation basin I has been completed, which certification should accompany an invoice for the District 's share of 50% of the Cooperative Project cost, but in no event to exceed $757 .50.

Haik, Attorney c/o Popham, Haik, Schnobrich & Kaufman, Ltd. 3300 Piper Jaffrey Tower Minneapolis, MN 55402 Re: Lake Riley Maintenance Project File No. 89-11 1 Dear Mr. Haik: This letter is in response to your letter dated July 17, 1989 regarding the Watershed District's request for additional information pertaining to the City's maintenance project at Lake Riley. The overall project consists of restoring an upstream sediment basin along with restoring the Lake Riley shoreline where the storm sewer outlets into Lake Riley. The sediment basin is located within the City's drainage easement on Lot 8, Block 1, Sunny Slope Addition. Over the years, sediments have filled in the sediment basin and wasned through the storm sewer system and created a delta in front of the storm sewer outlet. The project involves excavating, grading, culvert adjustment, baffle weir installation and turf restoration. Since the sediment basin is located within the City's drainage easement, the City's Public Works Department will perform future maintenance on the sediment basin. The City is looking forward to participating in a cooperative agreement for assistance in funding of this project. I have attached a cost estimate for the work involved in reconstructing the sediment basin. Should you have any questions in this matter, feel free to contact me.
