MEMORANDUM

TO: Paul Oehme, Director of Public Works/City Engineer
FROM: Terry Jeffery, Water Resources Coordinator 7(
DATE: November 10, 2008
SUBJECT: 2008 Surface Water Management Projects
b. Update Council on Progress
This is an informational presentation intended to apprise Council of the status of
Surface Water Management projects finished, implemented or designed in 2008.
BACKGROUND
Over the last year, eight significant water resources projects have either been
finished or constructed. These included the following:
1. The design and installation of environmental manholes along Laredo
Drive.
2. The Kerber Pond Water Quality Improvement Project.
3. Replacement of the stormsewer and outfall at the Sunrise Hills Estates
property.
4. The installation of a drop structure and rip rap at Ravine #2 south of
Mandan Circle as the first step in the stabilization of the ravine.
5. The rebuild of the pond located at Longacres Drive and Moccasin Trail.
6. The completion of the Foxford Road rain gardens.
7. The installation of a rain garden at the Lotus Lake boat landing.
8. The stabilization of the Utica Trail ravine.
In addition, two studies were initiated or completed in the past ten months. The
nondegradation assessment was completed and submitted to the Minnesota
Pollution Control Agency. The City has also begun sponsoring the Bluff Creek
Total Maximum Daily Load study with the Minnesota Pollution Control Agency
and Barr Engineering.
Staff is currently planning for the 2009 construction season. We have met with
the Cimarron Homeowners Association upon their request to evaluate the
feasibility of installing low impact development landscaping features throughout
their neighborhood. These will meet their desire to landscape the neighborhood
while meeting the City's need for additional water treatment and volume
reduction in the West-Central Lotus Lake Watershed.

Staff has been working with WSB & Associates, Inc. on two items. The first was
to prepare a feasibility report for addressing stormwater runoff in the Wesf:;.-
Central Lotus Lake Watershed. This item is also on the agenda for the
November 10, 2008 meeting. The other is to address drainage issues within the
Landings Court neighborhood. Staff hopes to have a solution to present to the
neighborhood in late November.
Finally, staffhas been working with the neighbors on Pleasant View Cove to find
a solution to the stream erosion occurring adjacent to Christmas Lake. Staffhas
met with several of the neighbors as well as with the Minnehaha Creek Watershed
District to procure funding and a plan to address the concerns.
It is also noteworthy that the Minnesota Department of Natural Resources has
completed the acquisition of Seminary Fen and the Seminary Fen SNA is now
open to the public. The City, the Lower Minnesota River Watershed District, the
DNR and Carver County Environmental Services are looking to collaborate with
each other to prepare a maintenance protocol for the Fen.
