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.
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
Stone Creek Drive for the 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.
39335Veport 6

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 in/right out traffic. No median crossing
will be provided when Highway 5 is upgraded in the future.
i
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
be the
'
the existing sidewalk near the school. The proposed sidewalk will along 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 Bouleva rd
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 / Drainage 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.
39335\report 7 '
I
n

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 mitigation will be 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
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 the 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.

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 b dividing the
Y g
total assessable cost by the assessable front footage for each road. Calculations are presented in
Appendix A.

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. For 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.
