Re: Coulter Boulevard
Plans and Specifications Approval
City Project 93 -26B
Our File 39335
Dear Charles:
a " im DEPT,
Attached for your approval are final plans and specifications for Project 93 -26B. The plans and
specifications were ordered on February 12, 1996. Since that time we have been working with the
adjacent property owners to have the project facilitate their proposed developments. The project will
need to be completed in two phases in order to give the land owners more time to prepare. In
addition, the segment of Stone Creek Drive south of Coulter Boulevard is now proposed to be
completed privately by the developer.
The first phase work proposed to be completed under this contract includes:
' 1. Sanitary sewer from the present end of Stone Creek Drive to the north side of Highway 5.
' 2. Water main from the existing west end of Coulter Boulevard to the existing east end of Coulter
Boulevard.
3. Storm sewer and wetland mitigation for Coulter Boulevard.
' 4. Coulter Boulevard street, sidewalk, lighting, and landscaping from the existing end near the
elementary school to the existing end by Pillsbury.
' A future phase will complete Stone Creek Drive north of Coulter Boulevard or at some other
location.
' The arch underpass funded by the federal ISTEA grant will be constructed under a separate project
expected to be approved in a few weeks.
1 2335 West Highway 36 ■ St. Paul, MN 55 113-3898 ■ 612 - 636 -4600
■
The estimated project cost for the work as originally proposed in the feasibility report has not '
changed. A current breakdown of the estimated project cost is:
93 -26B Phase I (this contract)
93 -26B Phase II (future)
93 -26C (Pedestrian Arch Underpass)
Private Construction (Stone Creek Drive)
$1,733,500.00
452,000.00
440,000.00
249,500.00

1.0 INTRODUCTION
The proposed improvements contained herein have been discussed conceptually by the City and area
land owners for the past few years. The necessary municipal improvements to serve the area south
of Highway 5 between Galpin Boulevard and Audubon Road will be completed with this project.
In addition, this project will extend the Bluff Creek trunk sanitary sewer north of Highway 5.
This report is the result of petitions from the affected property owners. Authorization for the report
was given by the City Council on November 13, 1995. Proposed developments in the project area
are planned by Land Group, Inc., Hi -Way 5 Partnership, and Heritage Development, Inc..
This report examines the feasibility of completing street and utility improvements in the project area.
Sewer and water service will be provided by extending utilities installed under previous projects.
A summary of the proposed improvements with this project includes:
Extension of trunk sanitary sewer from the Creekside Addition, along Bluff
Creek, and to the north side of Highway 5.
2. Looping of water mains and extension of trunk mains along Coulter Boulevard.
3. The construction of Coulter Boulevard between the existing termini of the road
at Pillsbury to the east and Bluff Creek Elementary School to the west.
4. The construction of Stone Creek Drive from the north end of Creekside Addition
to Highway 5.
5. The construction of a pedestrian/bicycle underpass under Coulter Boulevard, as
well as a boulevard trail along Coulter Boulevard.
Assessments proposed herein are consistent with City policy and the comprehensive sewer and water
plans. The project area is shown on Figure No. 1 on the following page. The proposed project
assessment area is shown on Figure No. 6. A preliminary Assessment Roll is presented in Appendix
B at the back of this report. The amounts shown in the preliminary Assessment Roll are based on
preliminary information and will be revised at the time of the final assessment hearing based on final
costs, development agreements, and final development plans.

2.0 SUMMARY AND RECOMMENDATION
This report presents an evaluation of the feasibility of constructing Coulter Boulevard and part of
Stone Creek Drive, as well as an evaluation of the trunk sanitary sewer and water main services
necessary to serve the project area. The report provides estimated costs of the proposed
improvements and presents a preliminary assessment roll for the construction. The total estimated
cost for this project is $2,805,500, including both construction and indirect costs. Further details of
estimated costs are presented later in this report.
Figure No. 2 at the back of this report shows the proposed sanitary sewer and water main
construction. Figure No. 3 shows the street, storm sewer, and trail alignments.
The proposed work is feasible from an engineering standpoint and can best be completed as one
contract. Based on the results of our investigation for this report, the following recommendations
are presented for the Chanhassen City Council:
1) That this report be adopted as the criteria for installation of the street and utility
improvements contained herein.
2) That the City review and adopt the proposed assessment and financing methods
contained herein.
3) That a formal public hearing be held to discuss the proposed improvements and
assessments. All properties that are proposed to be assessed and all properties near
the project area should be notified of the public hearing.

' 3.0 PROPOSED IMPROVEMENTS
' 3.1 Sanitary Sewer
Sanitary sewer improvements for the project area are generally in conformance with the City's
' Comprehensive Sewer Policy Plan and are shown on Figure 2. The project will extend trunk sanitary
sewer installed under previous projects and will provide lateral sewers where necessary. Sanitary
' sewer flow from the project area flows south along Bluff Creek and eventually reaches Lift Station
No. 24 on Lyman Boulevard.
t An 18 -inch diameter trunk sanitary sewer will be extended north along Bluff Creek from the existing
end of Stone Creek Drive to the north side of Highway 5. The alignment of the sewer will follow
t Stone Creek Drive for (lie first 400 feet. The remaining alignment will follow Bluff Creek. The
sewer crossing of Highway 5 will be aligned to facilitate the proposed Highway 5 pedestrian
underpass and the future north frontage road.
' An 8 -inch diameter sanitary sewer will be installed in Coulter Boulevard from Bluff Creek westward
to provide gravity service to the Bluff Creek School. The temporary lift station presently serving the
school will be salvaged for use elsewhere in the City.
' 3.2 Water Main
' Water main improvements proposed herein are consistent with the City's Water Supply and
Distribution Plan and are shown on Figure No. 2. A 12 -inch diameter main will be constructed in
Coulter Boulevard to loop existing dead end mains at Bluff Creek School and Pillsbury. In addition,
' an 8 -inch water main will be constructed in Stone Creek Drive from the north end of Creekside
Addition northward to Coulter Boulevard. A 12 -inch main will be installed in Stone Creek Drive
' north of Coulter Boulevard.
l
.9 „5Wport
3.3 Street. Trail, and Storm Sewer
A. Street The proposed street construction is shown on Figure No. 3. Coulter Boulevard will
be constructed to MnDOT State Aid standards between the existing dead ends near the
Bluff Creek School and the Pillsbury campus. Coulter Boulevard will be 36 feet wide (face
of curb to face of curb) in accordance with the typical section shown on Figure No. 4 and
City standards for streets in commercial /industrial areas. Right turn lanes will be
constructed at Stone Creek Drive to facilitate traffic flow. The alignment for Coulter
Boulevard has been established to meet the needs of the adjacent developments and
minimize environmental effects by reducing wetland impacts.
Stone Creek Drive will be extended from its existing terminus in Creekview Addition
northward to Highway 5. It will be 31 feet wide south of Coulter Boulevard and 36' wide
north of Coulter Boulevard.
Stone Creek Drive will connect to Highway 5 as previously established in the Highway 5
corridor study. The access will be limited to right inhight out traffic. No median crossing
will be provided when Highway 5 is upgraded in the future.
B. Trail Trail /sidewalk construction proposed is in accordance with the City's master trail
plan. A trail underpass is proposed at the east creek, which will allow users of the Bluff
Creek trail to cross Coulter Boulevard. Funding for the majority of the costs for the trail
underpass will come from Federal ISTEA funds.
An 8- foot -wide concrete sidewalk will be constructed along Coulter Boulevard to match
the existing sidewalk near the school. The proposed sidewalk will be along the north
boulevard west of the trail underpass and along the south boulevard east of the underpass.
Trail and sidewalk will be installed along Stone Creek Drive south of Coulter Boulevard
to complete segments constructed as with the Creekview development. No trail or
sidewalk is proposed for Stone Creek Drive north of Coulter Boulevard.
C. Storm Sewer / Drainaee: The City's storm water management plan suggests an area storm
water quantity /quality pond in the project area. However, the preliminary development
plans for the area are not set up for an area pond. This report assumes that each adjacent
development will address their drainage issues separately.
393354epon 7
Drainage from the roadway will be collected and conveyed through storm sewer at low
points in the roads to ponding areas adjacent to the creeks. On Coulter Boulevard, low
points will be located near the east side of the Bluff Creek crossing and near the west side
of the east creek crossing. On Stone Creek Drive, low points will be created in two
locations.
The Bluff Creek crossings will require 6 -foot by 3 -foot box culverts on both Stone Creek
' Drive and Coulter Boulevard. The east creek crossing will be accomplished by the
concrete arch trail /creek underpass shown on Figure No. 5.
'
Wetland be
mitigation will required as a result of the crossing of the wetland near Bluff
Creek. Part of the mitigation will be taken care of with existing banked acreage from
'
previous City water quality improvement projects. The remaining mitigation will be
addressed with wetland creation in the project area.
' 4.0 COST ANALYSIS / FINANCING
4.1 Cost Estimate
The estimated project costs to complete the street and utility improvements are presented below in
' Table 1. These costs include legal, administrative, engineering, bonding, and interest costs estimated
to be 30 %, but do not include any easement acquisition costs. It is assumed that all required
I easements will be granted by the adjacent property owners (including Grand Met and Shamrock
Property Partnership) at no cost to the project. A detailed cost estimate is included in Appendix A.

4.2 Assessments
Assessments are proposed to be levied against the benefited properties as shown on Figure No. 6.
The proposed assessments herein are consistent with City policies and practices. Proposed
assessments include the annually adjusted trunk sewer and water charges established in the
Comprehensive Sewer and Water Plans, lateral utility benefit charges, and street charges.
Street assessments are based on the following criteria:
• Abutting property owners are assessed for a standard 36- foot -wide, 9 -ton design
commercial /industrial roadway. The costs for Coulter Boulevard and Stone Creek
Drive are included in the front foot assessment rate for streets.
• Abutting property owners are assessed for 50 percent of drainage costs for the
roadway, including storm sewer and ponding. Site drainage improvements for
quality and quantity ponding will be addressed by each site independently.
Adjustments to this project plan will be based on the criteria in the City's SWMP
plan.
• Street grading costs are included as assessable costs. If the street grading can be
completed as part of the grading of the adjacent developments, the estimated
costs /assessments will be reduced accordingly.
A summary of the proposed Assessment Rates is presented in Table 2 below:

Assessable equivalent units for sewer and water area charges are determined by multiplying tite net
assessable acreage for each parcel by the number of residential equivalent units (REUs) for the
planned use. The REUs for various land use types are shown below in Table 3. Net assessable
acreage is gross acreage less wetlands and known major road right -of -way. The assessable
' equivalent units shown in the preliminary assessment roll are minimum numbers based on existing
zoning and land use guideline conditions. Calculations for final assessment purposes will be based
on actual development information at the time of the assessment hearing and will be adjusted if
' actual development intensifies.

' Residential Equivalent Units (REUs)
Minimum REUs Per
' Land Use TVDe New Assessable Acre

' Public 2
The above REUs are the minimum number recommended to be charged at the time that trunk utility
service is provided. if a property develops at a greater number of REUs, additional unit charges
' should be charged at the time of development.
' Street assessment rates for Stone Creek Drive and Coulter Boulevard are calculated by dividing the
total assessable cost by the assessable front footage for each road. Calculations are presented in

$2,156,800
$1,612,890
($543,910)
Coulter Boulevard
Table 4 shows a positive total project revenue for sanitary sewer and water main. The additional
revenue generated is to be placed in the sewer and water funds and applied to past and future trunk
water and sewer projects as shown on the most recent comprehensive plans. I'or example, some
revenue will be used to offset past costs such as the Bluff Creek Lift Station, and an additional well
and a future water tower will both be necessary to serve the project area.
The difference between the estimated cost and the assessments for Stone Creek Drive and Coulter
Boulevard represents the City share of storm sewer /drainage costs and the costs of the trail
underpass. The costs for the trail underpass will be reimbursed by federal ISTEA funds.

5.0 PROJECT SCHEDULE
The improvements described in this report should be constructed as one project in conjunction with
the proposed adjacent developments. The schedule shown below meets the needs of the proposed
developments. The City will require that the developers enter into a development contract with a
final plat or that assessment waivers be obtained from the underlying fee holders to the property
before final approval of plans and specifications. The schedule is based on completing constriction
in 1996 for building occupancy in the late fall. The project schedule could also be delayed to
postpone some street construction if adjacent developments request it.
