SUBJECT: Erie Avenue Area Street and Utility Reconstruction: Approve
Plans and Specifications; Authorize Advertisement for Bids
Project No. lO-OI(a)
PROPOSED MOTION
"The City Council is recommended to approve the plans and specifications for
City Project No. 10-01(a), Erie Avenue Area Street and Utility Reconstruction
Project and authorize the advertisement for bids.
City Council approval requires a simple majority vote of the City Council
present. "
BACKGROUND
On July 13, 2009, staff discussed the proposed 2010 street improvement projects
with Council at the work session.
City Council authorized the preparation of the 2010
Street Reconstruction Project at the September 14,
2009 City Council meeting.
The Capital Improvement Program had planned for
reconstructing the Erie Avenue neighborhood
(Chanhassen Estates, south of Lake Drive East) and
the Red Cedar Point neighborhood this year. The
streets proposed for reconstruction were chosen using
the City's Pavement Management Program and were
identified due to utility problems in the area.
Staff held a neighborhood meeting for this project on
November 11, 2009.

SCOPE OF PROJECT - ERIE AVENUE AREA
Streets
It is proposed that 0.73 miles of streets in this area be
reconstructed. The streets in the Erie Avenue
neighborhood are 38 years old and cannot be maintained
properly with minor maintenance or even a bituminous
overlay. The streets are in poor condition with an average
pavement condition index of 28; a road under 45 typically
indicates distress that would require a full depth
reconstruction.

Dakota Lane and Erie Circle were overlaid by City crews
with a thin layer of bituminous pavement in 2001 due to
severe washouts and distressed pavement areas. The
average pavement condition index of these streets is
currently 52, which is higher than most of the other streets,
however, it is anticipated these streets will degrade more
quickly in the coming years. These streets should be
included when the Erie Avenue area is reconstructed so a gap of old street section is not left.
Soil borings were obtained for this project area. All borings showed less than 12 inches of
aggregate base, which is the minimum amount recommended by the soils engineer. A
bituminous overlay would not correct the poor sub grade that exists in the project area.
Sidewalks and street lights are not proposed to be included.
Sanitary Sewer
The sanitary sewer in the project area is 8-inch vitrified clay pipe and was installed in 1971. The
sanitary sewer has been televised and shows many areas of groundwater leaking into the pipe
and settled pipes that do not flow well anymore. Some of the sanitary sewer services show root
intrusion into the pipe. Due to the condition of the pipe, all of the sanitary sewer laterals and
services within the right of way are proposed to be replaced.
Watermain
The watermain in this area is eight inches in diameter cast iron pipe and has nine documented
breaks. Due to the condition and material, all of the watermain and water service pipes in the
right-of-way are proposed to be replaced.
Storm Sewer
Storm sewer is currently at the intersection of Dakota Lane and Cheyenne Avenue and
discharges to a drainage swale to the wetland to the south. The swale is eroding, therefore
additional storm sewer is proposed to be installed to capture the runoff and discharge to a
stormwater pond.

The proposed storm sewer in Erie Circle will capture runoff from the remainder of the streets.
The existing bituminous-lined swale from the cul-de-sac to the park area will be replaced with a
filtration area. The existing two, 18-inch culverts will be replaced with a 21-inch culvert. No
additional storm sewer pipe is proposed to be added between any properties. It was anticipated
to directional drill a new storm sewer pipe in between two parcels to eliminate the drainage
going into the deep ravine. This design however was not able to work from a hydraulic
perspective due to lack of grade by the trial. Staff will be working with the property owners
adjacent to the ravine and see if any improvements could be made to the steep ravine
embankments.
Permits and Approvals
Reconstruction ofthe roadways will disturb over one acre and will require a National Pollution
Discharge Elimination Systems (NPDES) General Storm Water Permit (MNR 100001) that must
be obtained by the City of Chanhassen from the Minnesota Pollution Control Agency (MPCA).
Replacement of the sanitary sewer and watermain will require permits from the Minnesota
Pollution Control Agency (MPCA) and the Minnesota Department of Health (MDH),
respectively.
Private Utilities
Existing private utilities consisting of gas, electric, telephone, and cable are underground within
the right of way. Coordination with the private utility companies will need to be made to
maintain service to the property owners.
FUNDING
Forty percent (40%) of the street reconstruction costs is proposed to be assessed back to the
benefiting property owners; the remaining 60% of the street costs would be a City cost. The
City's share of the street costs will be paid out of the Revolving Street Assessment Fund. The
utility costs are proposed to be paid 100% out of the respective utility fund. The estimated costs
and funding for the project is summarized as follows:

Description I
Annual project to rehabilitate and reconstruct streets in the City. Current 5-year plan shows the following neighborhood areas:
- Residential 2010 - Erie Ave area and Red Cedar Pt (Reconstruction)
2011 - Timbetwood, Saratoga, Santa Vera, Chippewa, Picha and Kerber (S ofW 78th)
2012 - Greenbriar; Fir Tree, Ehn Tree, Dogwood, Shore Drive and Maplewood Circle (Reconstruction)
2013 - Greenwood Shores
2014 - Dartmouth Drive and Cypress Drive
MSA 2011 - West 78th Street (Powers to Marken
Justification I
The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative 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 poor sub grade needs to be replaced or where streets have deteriorated
to a point where rehabilitation will no longer be practical reconstruction of the street is necessary. A feasibility study is written to consider the
merits of the project and scope ofwork.

Description I Total Project Cost: $825,000
I This annual project includes televising, repairs and rehabilitation of existing sanitary sewer. The program also detects and eliminates points of entry
of ground water and surface water into the City sanitary sewer system. Projects have been identified from the 2006 Inflow and Infiltration Report.
The projects were reviewed by Metropolitan Council and approved in lieu of surcharge fees.
I
Justification I
I City staff has identified nmnerous older sewer lines that are in need of repair. The City of Chanbassen pays the Metropolitan Council for sewage
treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its
way into the system either .through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to
I the City for sewage disposal and. increasing the load on the City's lift stations. Also, MCES would place a surcharge on the annual charge if the
City was not actively trying to reduce the inflow and infiltration problem.

I Budget Impact/Other I
The efforts may decrease operational costs, MCES fees and emergency call outs. It is also the City's intent to use connection charges to help fund
I for those costs. It is the City's belief that as new customers come on line those connection fees sbould help fund future infiltration problems.
