RE: Cooperative Project - City of Chanhassen
City Project #89-11
I
Dear Mayor and Council:
At their last meeting, the Board of Managers of the
I
Riley-Purgatory-Bluff Creek Watershed District authorized a
Cooperative Project with the City of Chanhassen to restore an
upstream sedimentation basin to prevent the continuing discharge
of erodable material to Lake Riley. 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. Please acknowledge this I

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.
Sincerely,
CITY OF CHANHASSEN
