Discuss 2006 Street Improvement Project - Project No. 06-01
DISCUSSION
Staff would like to beginning working on the 2006 Street Improvement Project.
The Capital Improvement Program had planned for reconstructing the south half
of Audubon Road and the Koehnen Circle/63fd Street area and milling and
overlaying the Chanhassen Hills Drive area. However, with the updated TH 212
schedule, staff is recommending delaying the Audubon Road improvements until
2008.
The 2006 street improvement areas were selected based on the City's Pavement
Management Program and because of utility problems in the Koehnen Circle/63fd
Street area. The streets in the Koehnen Circle/63fd Street area are 34 years old
and cannot be maintained properly with minor maintenance. The streets are
typically a rural section with some bituminous curb. The watermain in this area is
cast iron pipe and continuously breaks. Over the last ten years, staff has
documented 23 breaks in this neighborhood. Also, the sanitary sewer in most of
this area has become deflected and can no longer be cleaned and inspected by the
utility crews. The storm sewer system in this area is poor and staff routinely
receives complaints from the residents about standing water on the road and in
yards. Included in the Stormwater Management Plan contract was preliminary
stormwater routing and water quality review for this area. Staff has begun to
discuss storm sewer improvements with some of the residents and installation of
small ponds. Drainage and utility easements would need to be acquired if these
improvements were made.
The scope of the Koehnen Circle/63fd Street area project would be to reconstruct
the street to current City standards for a residential area with concrete curb and
gutter. The roadway width is anticipated to match existing conditions. All the
cast iron watermain would be replaced and it appears most of the sanitary sewer
system will need to be replaced. A final determination on the scope of the
sanitary sewer improvement would be included in the feasibility study. A storm
sewer system and water quality improvements would also be included in the
project.

The streets in the Chanhassen Hills Drive area are 19 years old and have poor
surface drainage. The streets can no longer be maintained properly with minor
maintenance. The Pavement Management Program recommends these streets for
resurfacing.
Budgets for the proposed work have been updated from the 2005 CIP. The total
estimated project cost is $2,540,000.
The estimated funding project cost is as follows:
Funding
Assessments
$600,000.00
$900,000.00
$310,000.00
$380,000.00
$350,000.00
$2,540,000.00
Revolving Assessment Fund
Sewer Fund
Water Fund
Storm Sewer Fund
Assessment will be based off the City's assessment practice of assessing 40% of
the street improvements to the benefiting properties on a per lot basis. The
assessments would be proposed for 8 years with 6% interest. A consultation
report for the Koehnen Circle/63fd Street area would be drafted to help determine
the final assessment amount. One Hundred Percent (100%) of the utility and
stormwater improvements would be funded out the respective utility funds.
With all improvement projects the Engineering department plans, several
neighborhood meetings would be held to answer any residential questions about
the proposed improvements and assessment. These meetings also give staff an
opportunity to gather additional information about the area to help make the
project successful.
Staff is currently working on a request for proposals for engineering services and
hopes to have proposals back shortly for Council approval. The engineering
services would include feasibility report preparation, final design and construction
services. With all engineering consultant contracts, payment would be made on
an as performed basis.
