SUBJECT: Order Preparation of and Accept Feasibility Report and Call the
Public Hearing for the Koehnen/Yosemite Road Improvement
Project - Project No. 07-01
REQUESTED ACTION
Council is requested to order preparation of and accept the Feasibility Report and
call the Public Hearing for the Koehnen/Yosemite Road Improvement Project -
Project No. 07-01.
BACKGROUND
On September 26, 2005, Council authorized the preparation of the 2006 Street
Improvement Feasibility Report.
On January 9, 2006 Council accepted the feasibility report and called for the
public 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 project.
On September 25,2006 Council approved the Professional Services Agreement
Addendum.
DISCUSSION
The City's consultant for this project, Bolton & Menk, Inc. will provide a
feasibility report to help determine the final assessment amount to be assessed to
the benefiting property owners. The feasibility report will include all aspects of
the project proposed.
The City 01 Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

The area proposed for street reconstruction is northwest of Yosemite A venue and Lake Lucy
Road. Approximately 1.05 miles of roads are proposed for reconstruction, including Yosemite
Avenue from 6481 Yosemite Avenue to the City limits, West 63rd Street from Yosemite Avenue
to Cardinal Avenue, Audubon Circle, Blue Jay Circle, Cardinal Avenue from West 63rd Street to
the City limits, Koehnen Circle West and Koehnen Circle East. Included in the project will be
storm sewer, watermain and sanitary sewer improvements.
These proposed improvements were identified using the City's Pavement Management Program
and because of the utility problems in these areas.
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
A venue (from 6440 Yosemite A venue 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 lO-year period at 6% interest. Final
assessment amounts will be based on the construction costs.
Approximately 25 residents attended the Koehnen area open house on December 8, 2005. The
following generalizes the questions and comments received at the open house:
. Why are the anticipated assessment costs so high?
. Who decided that these roads need to be reconstructed?
. Why is the City's standard cul-de-sac 90 feet in diameter? It seems large.
. Upgrading Yosemite will increase the traffic volume on the road.
. Will trees be removed?
. What is the proposed timeline for this project?
