Receive Feasibility Study and Call for Public Hearings for the
2006 Street Improvement Project No. 06-01
BACKGROUND
On September 26, 2005, Council authorized the preparation of the 2006 Street
Improvement Feasibility Report.
On December 8, 2005, staff held an open house meeting with residents in the
Koehnen neighborhood to discuss the proposed street and utility reconstruction
project.
On December 15,2005 staff held an open house meeting with residents in the
Chanhassen Hills neighborhood to discuss the proposed street rehabilitation
project.
DISCUSSION
The street improvements proposed for 2006 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 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
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.

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 $7,100110t and is proposed to be
assessed over a lO-year period at 6% interest.
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?
All property owners' questions were answer at the meeting or with a follow up
letter or phone call.
The project and the feasibility report also include resurfacing or rehabilitation of
the streets in the Chanhassen Hills neighborhood. These streets are 15 years old
and are recommended for milling and overlaying. Improvement consists of
milling the pavement and paving a minimum of 2" bituminous. Damaged
"alligatored" pavement areas will be removed and repaved prior to the overlay.
Severely damaged curb will be replaced. Some draintile will be included in the
project.
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 Chanhassen Hills area is $1,698.15110t and is proposed
to be assessed over an 8-year period at 6% interest.
Four residents attended the Chanhassen Hills area open house on December 15,
2005. The following generalizes the questions and comments received at the
open house:
Paul Oehme
January 9, 2006
Page 3
. Why doesn't the City pay for the entire project cost?
. Who decided these streets need to be worked on?
. What is the project schedule?
. Will Draintile be included in the project?
All property owners' questions were answer at the meeting or with a follow up
letter or phone call.
Final assessment amounts will be based on the consultation report the
Engineering Department is working on with the City Attorney. This report is
expected to be completed by the end of January, 2006.
Also included in this year's street project are proposed improvements to the
parking lots at Lake Ann Park. Most of the drives and parking areas are in very
poor condition and are in need of reconstruction. The improvements include
reconstruction of the roadways, realignment of roadways, reconstruction of
parking areas and overlay of parking areas. Also included will be placement of
concrete curb and gutter in parking areas.
These components of the project and the feasibility report will be presented to
City Council at the next meeting prior to the public hearing. Copies of the
feasibility report are available in the Engineering Department.
Funding for this project is proposed as follows:

The estimated costs for storm sewer improvements are higher than the budgeted
amount since the detailed storm sewer design was not complete when the budget
amount was determined.
The estimated watermain costs are high due to the unforeseen increase in the cost
of watermain pipe.

Description
Annual project to rehabilitate and reconstruct streets in the City. Current 5-year plan shows the following neighborhood areas:

Justification
The City uses a Pavement Management System to monitor the condition of the City streets. While proper maintenance extends the life of the street and is cost
effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. Rehabilitation projects extend the life of the street. In
cases with utility or sub grade issues, reconstruction of the street is necessary. A feasibility study is written to consider the merits of the project and scope of work.

better coordination when we need to replace water and sewer lines with replacing roads. .
