MEMORANDUM
TO:
Todd Gerhardt, City Manager
FROM:
Teresa J. Burgess, Public Works Director/City Engineer
DATE:
September 17, 2003
SUB J:
Approve Feasibility Study; Authorize the Preparation of Plans &
Specifications for the 2004 Residential Street & Utility
Improvement Project No. 04-01
REQUESTED ACTION
Hold the public hearing and authorize preparation of Plans and Specifications for
Project No. 04-01.
DISCUSSION
Attached is a final draft of the feasibility study for this project. The following
changes have been made from the draft previously received:
1. Number of parcels to be assessed has been adjusted from 33 to 32 to
match the City's Assessment Practice.
2. Added information on the existing sanitary sewer and watermain to be
more descriptive of existing condition.
3. Added Pavement Condition Index (PCI) ratings to show existing
pavement condition.
4. Minor typographical errors were corrected.
Staff recommends that to reduce confusion, Council call property owners by
streets as grouped below for the public hearing with a brief introduction of the
existing condition and proposed improvements by staff as each group is called.
Streets have been grouped that are similar in condition and are proposed to
receive similar improvements.
Kiowa, Iroquois, and Huron Drives
The existing surface is in reasonable condition. The street will eventually
need full depth reconstruction due to significant utility issues, however,
the consultant, based on televised inspection of the existing sanitary sewer
and review of logs of watermain breaks has recommended spot repairs in
23 locations. The improvements include repairs to cracked pipe,

misaligned pipe, removing tree roots, and replacing service wyes. It is
proposed these 23 locations be excavated for the repairs and then patched.
Normally the City would delay these improvements until the street was
being done, however, the extreme joint displacement is causing problems
with inflow of groundwater, tree roots blocking the pipe, and most critical
is causing poor function in the sanitary sewer including back-ups into
homes in the area. The City does not have adequate funding in 2004 to
include this section in the reconstruction project. The spot repairs will
postpone the need to fully reconstruct this section of roadway by an
estimated 5-7 years.
Santa Fe Trail and Del Rio
· Watermain: The existing cast iron pipe was installed in Santa Fe
Trail was installed in 1967. The pipe in Del Rio was installed in
1969. Expected functional life for watermain is 30-40 years. The
City's clay soils are highly acidic and accelerate the aging of the
pipe. The consultant has recommend replacement of the watermain
with PVC to address this issue.
Sanitary Sewer: The existing clay pipe was installed at the same
time as the water main. The sanitary sewer is in similar condition to
that on Kiowa, Huron, and Iroquois, however, delay of this project
7 years is not recommended with a project similar to that one due to
the condition of the pavement and water main. The consultant is
recommending full replacement of the sanitary sewer.
Storm Sewer: The existing storm sewer does not adequately address
the existing runoff due to intensification of development since its
installation. Nor does the storm sewer system address current
standards for storm water quality. The consultant has recommended
improvements to the system storm sewer pipes and catch basins to
address the quantity of storm water.
Sidewalk: City standards call for a 5' sidewalk on one side of
residential streets. A sidewalk has been proposed, however, Staff
recommends that the issue of whether or not to install the sidewalk
be decided by the property owners as part of the design process.
Pavement: The current PCI is 56 for Santa Fe Trail and 70 for Del
Rio Drive. General streets with a PCI of 40-60 fall into the
reconstruction classification, however, the significant utility work
required on this project preclude the possibility of pavement
rehabilitation instead of reconstruction.

Santa Fe Circle (East and West)
· Watermain: The existing cast iron pipe was installed both circles
Santa Fe Trail was installed in 1967. Expected functional life for
watermain is 30-40 years. The City's clay soils are highly acidic and
accelerate the aging of the pipe. The consultant has recommend
replacement of the watermain with PVC to address this issue.
· Sanitary Sewer: The existing clay pipe was installed at the same
time as the watermain. The sanitary sewer is in similar condition to
that on Kiowa, Huron, and Iroquois, however, delay of this project 5-
7 years is not recommended with a project similar to that one due to
the condition of the pavement and water main. The consultant is
recommending full replacement of the sanitary sewer.
· Storm Sewer: The catch basins do not meet City standards. In
addition, the drainage from Santa Fe Trail runs into the cul-de-sac
and causes further issues. The consultant has recommended
improvements to the system storm sewer pipes and catch basins to
address the quantity of storm water and "rain gardens" to address
water quality. The issue of rain gardens will need to be further
explored as part of the design process to gain property owner input
and define maintenance responsibilities. Also, the rain gardens may
have impacts on the desired use of the cul-de-sac that need to be
discussed by the property owners once a radius has been designed
and can be marked on the street for comment and discussion.
· Sidewalk: The sidewalk proposed on Santa Fe Trail and Del Rio
Drive will also serve this neighborhood although no sidewalk is
proposed in the circles themselves. Staff recommends that the
sidewalk issue be decided by the neighborhood as part of the design
process.
· Pavement: The current PCI is 52 for the eastern circle and 40 for the
western circle. General streets with a PCI of 40-60 fall into the
reconstruction classification. Both of these streets falls into this
classification. Delay of the project is further undesirable due to the
significant utility work necessary.
FUNDING
This project is proposed to be funded with a combination of assessments and
bonding.

I. Introduction/Summary
This report presents information concerning the proposed 2004 Residential Street Improvement
Project (City Project 04-01). The project is part of the City's ongoing annual street improvement
program.
Municipal improvements proposed herein include sanitary sewer replacement, water main
replacement, drainage improvements, and street reconstruction. This report was initiated by the
City Council on April 23, 2003.
The costs of the proposed improvements are detailed in Appendix A. Cost allocation and a cost
summary are presented in the Cost Analysis section. Financing for the project will come from
assessments, the water fund, the sewer fund, the pavement management fund and the surface
water management fund.
Assessments proposed in this report are consistent with past projects and Council direction
concerning assessment methodology. A copy of the current city assessment practice is attached
as Appendix C. The proposed project assessment area consists of 32 lots and is shown on Figure
4. The proposed assessments are based on the preliminary cost estimates and may be revised at
the time of the final assessment hearing.

II. Proposed Improvements
Sanitary Sewer Repairs in Kiowa, Iroquois, and Huron Area.
In April of 2003 the Public Works Department engaged Infrastructure Technologies to complete
a television inspection of the sanitary sewer in the neighborhood that includes West 76th St.,
Chan View, Kiowa, Iroquois, and Huron. Segments of the sewer in this neighborhood were
previously lined in the early 1980's.
The results of the 2003 television inspection indicate that the sewers in the neighborhood are in
poor to fair condition. Specifically, 23 spot locations were identified that need to be repaired
soon. The required improvements include repairing cracked pipe, repairing misaligned pipe,
removing tree roots, and replacing service wyes. It is proposed to repair these 23 spot locations
by excavating them and patching the street. The sewer repairs in this neighborhood are proposed
to be included in the 2004 Residential Street Project because of their close proximity to the Santa
Fe area and because including the sewer repairs with the larger project should result in better
bids.
Sanitary Sewer Replacement in Santa Fe and Del Rio Area.
The existing sanitary sewer in the Santa Fe and Del Rio area consists of 30+ year old clay pipe.
The sanitary sewer has been inspected and has been determined to be in an unacceptable
condition. It is proposed to replace all sanitary sewer in the project area as part of the overall
street project. Sewer replacement will include replacing sewer pipe, service wyes and any
substandard manholes.
Water Main.
Existing water main in the Santa Fe and Del Rio area consists of 30+ year old cast iron pipe.
The acidic, clay soils in Chanhassen have deteriorated the pipe over time, as a result, there have
been eight water main breaks in the past ten years in the area. As part of the street project it is
proposed to replace all existing water main with PVC main. Replacing the existing water main
will include replacing all hydrants and valves.
Sanitary Sewer and Water Services.
Individual sanitary sewer and water services for homes in the project area will be replaced to the
right-of-way line as part of this project. Replacement of the sanitary sewer services will include
new 6-inch pipe. Replacement of the water services will include new service pipe and new curb
boxes.
Drainage.
Drainage improvements are proposed as part of the overall street project. Short storm sewer
laterals will be extended at some intersections to provide better collection of surface drainage. In
addition, subsurface draintile will be installed along each side of the reconstructed streets to
improve the subsurface drainage and to provide outlets for residential sump pump drainage.
Water quality improvements are also proposed as part of the project. Sediment trapping sump
manholes and catch basins will be installed where necessary. In addition, water quality "rain
gardens" are proposed to be constructed in the center or the two cul-de-sacs (Santa Fe Circle
West and Santa Fe Circle East). Rain gardens are temporary ponding and sediment removal
areas that are landscaped with plants that can withstand the conditions. It is proposed to
construct the rain gardens on Santa Fe Circle East and Santa Fe Circle West in the middle of the
cul-de-sacs as "center islands". Drainage from the rain gardens will be conveyed to the existing
storm sewer through subsurface drains and through overflow piping.
Street.
The streets proposed to be included in this project have been identified as requiring
improvements by a previous Pavement Management Study. The Pavement Management Study
included a surface condition evaluation of all streets in the City and assigned each street segment
a Pavement Condition Index (PCI). Generally streets with a PCI in the range of 40-60 require
some surface reconstruction. With the amount of subsurface utility work included with this
project, a full street reconstruction is the only feasible improvement option. A summary of the
PCI information from the Pavement Management Study for the streets in the project area is
attached as Appendix D.
.b'~;osibi/i(; .R~¥~orS/br pr~?jecI 2004 Resicjer,~io/ Street Improvemc;a~s Pc~g~.~ 5
Street improvements proposed include total reconstruction of Del Rio (between Laredo and
Santa Fe), Santa Fe Trail, Santa Fe Circle East and Santa Fe Circle West. The reconstructed
streets will be close to the existing street widths. Street construction will include removing the
existing street surface, excavation for a new street base, and construction of a new street. The
street section will match the city's standard section and includes:
1.5-inch bituminous wear course (pave in 2005)
2-inch bituminous base course (pave in 2004)
· B618 concrete curb and gutter
· 12-inch Class 5 aggregate base
24-inch granular borrow
· draintile
geotextile fabric (where necessary)
Street construction will include driveway repair with in-kind surfaces. In general, driveways will
be removed 5 to 10 feet behind the edge of the street to fit in with the new street grade. Concrete
driveway aprons will be placed for all driveways, and the area beyond the concrete apron will
match the existing driveway surface.
Sidewalk.
In accordance with city practice for new streets, a sidewalk is proposed for one side of Santa Fe
Trail and Del Rio. The sidewalk will consist of a 5-foot wide concrete walk located on one side
of the street.

APPENDIX C
City of Chanhassen Assessment Practice
CITY OF CHANHASSEN
ASSESSMENT PRACTICE
This Assessment Practice is intended to provide direction to City Staff in preparation of assessment roles to ensure fair and
consistent treatment of all properties within the City of Chanhassen.
MAINTENANCE:
(Pothole filling, Patching, crack sealing, seal coat)
Maintenance costs are not assessed to abutting property owners. Maintenance costs are financed
through the City's Annual Budget process.
REHABILITATION:
(Repair of problem areas to full depth, Milling of edge or full width of existing pavement, Repair to existing catch basins and/or
curb and gutter, Pavement Overlay)
Rehabilitation costs are assessed using the following formula:
Total Project Cost =
60% Paid by City
(City share may be MSA, General
Fund, TIF, Federal or State Grants,
etc.)
40% Assessed to
abutting Property
Owners
Residential properties that abut collector or commercial streets shall be assessed using the same
formula, however, the assessments shall be reduced to be equivalent to a typical 31' residential
street section.
RECONSTRUCTION:
(Removal of existing street and construction of new street,. May include sanitary sewer or watermain work, May recycle the
existing asphalt as gravel base)
Reconstruction costs are assessed using the same formula as Rehabilitation.
NEW CONSTRUCTION:
(Construction of new street or utilities or a significant upgrade from the previous facilities, i.e. a 4-lane street replaces an
existing 2-lane.)
New Construction will be assessed 100% to the benefiting properties.
NOTE:
If a feature (sanitary sewer, water, curb and gutter, etc.) that did not previously
exist is added during a rehabilitation or reconstruction, the cost of that item is
treated as new construction with the remaining project costs being treated as
rehabilitation or reconstruction.
WORK DONE BY CITY CREWS:
Work done by City Crews may be maintenance, rehabilitation, or new construction. This work is
not typically assessed. Exceptions would include work associated with an assessment agreement
signed by the property owner and approved by the City Council and work specifically authorized
by the City Council to be done by City Crews and assessed to the abutting properties.

Subject: cul-de-sac comments
September 17, 2003
To: Teresa Burgess, City Engineer
From: Mark Littfin Fire Marshal
Subject: Center islands in Cul-de-sac's
It has been brought to my attention that there is discussion regarding proposed center
islands in the cul-de-sacs on Santa Fe. The Fire Dept. has some concerns regarding these
islands I would like to share with you.
1. Fire Department operations can be greatly hindered due to parking area being
eliminated by the island' s. Vehicles may wind up having to park a greater distance
from the fire slowing firefighting operations.
2. With the island installed, no parking of any vehicles would be allowed in the cul-
de-sac. Even 1 vehicle illegally park would prevent fire apparatus from driving
around and thru the turnaround.
3. Setting up our aerial platform truck would be compromised due to the narrowness
of the turnaround. To properly set up the truck, the outriggers need a minimum of
18 feet clearance. The center island and parked cars could prevent us from using
this vehicle.
4. The current dimensions of the Santa Fe cul-de-sac's are already below today's city
standards for new installations. In the event of a fire the parking space would very
quickly get overcrowded resulting again parking at a greater distance from the fire.
5. With the addition of center islands in any size cul-de-sac, we occasionally loose
the option of turning around vehicles quickly. When that happens, we have to
jockey them forward and backwards, 2 to 3 times, which is time-consuming. Even
with today's current design standards, when 1 or 2 vehicles are parked in a cul-de-
sac, the forward and backward method of turning around is sometimes our only
option.
6. If you have any questions or comments that I can elaborate on please feel free to
call me. The center islands may look nice when installed, but on the whole they
can block the view of the fire hydrant, and greatly hinder fire apparatus
accessibility as well as fire ground operations.
