Improvement Feasibility Report.

hearing for the project.
On January 23,2006 Council held the Public Hearing for the Koehnen area
reconstruction project.
In April, 2006 it was determined that the reconstruction project could not be completed
until late fall, 2006 due to the MNDOT State Aid Review process for the Yosemite
A venue portion of the project.
On April 10, 2006 Council approved deleting the Koehnen area reconstruction from the
06-01 proj ect.
On September 25, 2006 Council approved the Professional Services Agreement
Addendum.
On November 8, 2006 Staff hosted a Neighborhood Meeting
On November 13,2006 Council authorized and accepted the Feasibility Study and
called the Public Hearing.
DISCUSSION
These proposed street improvements were identified using the City's Pavement
Management program and because of the utility problems in the area.
Streets are recommended for reconstruction in the Koehnen area. These streets are 35
years old and are in need of replacement and do not have concrete curb and gutter. The
reconstruction area includes approximately 1.05 miles of street, including West 63rd
Street, Koehnen Circle East, Koehnen Circle West, Cardinal Avenue, Blue Jay Circle,
Audubon Circle and Yosemite Avenue (from 6440 Yosemite Avenue to the City limits).
Concrete curb and gutter will be included in the street design. Also, the street
improvement project will include replacement of all watermain, replacement of some
sanitary sewer, installation of storm sewer and construction of storm water treatment
ponds.

The watermain in this area is cast iron which has resulted in 23 documented watermain breaks. It is
recommended to replace the watermain in this area along with the water services in the right-of-way.
Televising of the sanitary sewer indicates that portions of this utility are "egged", sagging and/or cracked.
Bolton & Menk, the consultant engineer the City has contracted for this project, recommends that
portions of the sanitary sewer exhibiting "extreme" sagging or segments that are cracked be replaced.
Storm sewer will be installed and will outlet to one of three ponds that will be constructed in conjunction
with the project. The ponds will treat the runoff before discharging to other water bodies.
Forty percent (40%) of the street rehabilitation costs are proposed to be assessed to the benefiting
property owners within the project area. The preliminary assessment amount for the Koehnen area is
$7,100/lot and is proposed to be assessed over a 10-year period at 6% interest. The total estimate
assessment amount is $468,600.00.
Approximately seven residents (representing five properties) attended the open house on November 8,
2006. The following summarizes the questions, comments and concerns heard at the open house. All
property owners' questions were answered at the meeting or with a follow-up letter or phone call.
. What is the estimated time to complete the project?
. What type of curb will be installed?
. Will Yosemite be wider?
. Can vacant parcels be assessed?
· Can Shorewood assess us in the future for street improvements?
. Will I have access to my property?
. Will mail delivery be interrupted?
