Jamaica Avenue (Indian Boulevard to Military Road) Street Improvements 1
CITY OF COTTAGE GROVE
PROJECT SUMMARY
INTRODUCTION
This report addresses the proposed improvements for Jamaica Avenue between Indian Boulevard
and Military Road (C.S.A.H. 20), and 70 Street South (C.S.A.H. 22) between 1600 feet west and 700
th
feet east of Jamaica Avenue. Jamaica Avenue, north of 70 Street is showing significant signs of
th
surface deterioration. City Public Works staff continue to patch and repair this road segment on a
regular basis.
The proposed improvements include constructing a roundabout at the intersection of Jamaica and
70 Street; including storm sewer, concrete pavement, trail extensions, lighting, irrigation, and
th
landscaping. Jamaica Avenue, both north and south of 70 Street, are proposed to be reclaimed
th
and a new bituminous section constructed. 70 Street is proposed to be reconstructed to include
th
turn lanes into the Dodge Nature Center. The general project location is shown below in Figure 1
below. It is anticipated that this project would be constructed during the 2016 construction season.
PROJECT SCOPE
This project consists of street improvements in the general location shown in Figure 1 below.
Figure 1 Ï General Project Location
Jamaica Avenue (Indian Boulevard to Military Road) - Street Improvements 2
RI
EQUIRED MPROVEMENTS
The project includes improvements to Jamaica Avenue between Indian Boulevard and Military
Road; and 70 Street South between 1600 feet west and 700 feet east of Jamaica Avenue (see
th
figure 2 in the appendix of this report). A roundabout at the intersection of Jamaica Avenue and
70 Street, public trail extensions, street lighting and landscaping are all included in the proposed
th
improvements to be constructed in 2016.
S
TREET IMPROVEMENTS
The intersection of Jamaica Avenue and 70 Street currently exists as a four way stop controlled
th
intersection. This intersection is proposed to be reconstructed with a roundabout (see figure 3 in the
appendix of this report). The proposed roundabout will be constructed with concrete curb and
gutter, concrete pavement and landscaped medians.
Jamaica Avenue, north of the roundabout, is proposed to be fully reconstructed to the north
property line of the Rose of Sharon Church. Jamaica Avenue, north of the Rose of Sharon Church
north property line and south of the roundabout, is proposed to be reclaimed and a new section of
bituminous placed. To minimize costs related to future adjoining development construction north of
the Rose of Sharon Church an interim pavement section (16 foot bituminous with 8 foot gravel
shoulder) will be constructed. A full access to Jamaica Avenue is proposed for the Rose of Sharon
Church.
70 Street is proposed to be reconstructed to provide turn lanes into the Dodge Nature Center. The
th
Dodge Nature Center is proposing to start school programs on site in 2016. A bypass will be
constructed on the north side of 70 Street to allow east/west traffic to be opened during this
th
project (see figure 6 in the appendix of this report). Short closures on 70 Street may be required
th
during roundabout construction.
A cost estimate has been included in the appendix of this report. All street improvements will be
designed to meet Municipal State Aid, City of Cottage Grove and Washington County Standards.
TSI
RAIL AND IDEWALK MPROVEMENTS
Eight-foot wide bituminous trails are proposed to be extended on both sides of Jamaica Avenue
Street. The trail on the west side of Jamaica Avenue is proposed to be extended to 67
north of 70
thth
Street Court South. The trail on the east side of Jamaica Avenue is proposed to be extended to the
northern access of the Rose of Sharon Church. Portions of the existing sidewalks on Jamaica Avenue
south of 70 Street are proposed to be realigned to connect into the proposed roundabout.
th
SLI
TREET IGHTING MPROVEMENTS
Street lighting is proposed to be installed within the four legs of the roundabout. The lighting,
including the roundabout landscaping lighting, will be very similar to the lighting installed in the
roundabout at the intersection of 70 Street South and Keats Avenue. Ravine style lighting is
th
proposed to be installed on both sides of Jamaica Avenue; north of the roundabout to the north
property line of the Rose of Sharon Church.
LI
ANDSCAPING MPROVEMENTS
The intent of this project is to provide landscaping and irrigation to the roundabout and median
areas (see figures 7 through 10 in the appendix of this report). The landscaping will include
hardwood trees, shrubs, perennials, ornamental grasses, limestone blocks within the Jamaica
Jamaica Avenue (Indian Boulevard to Military Road) - Street Improvements 3
Avenue median area and proposed monumentation. Breakoff or crash worthy monumentation
options proposed for the center of the roundabout are currently being reviewed by the County.
UI
TILITY MPROVEMENTS
An 8 inch water service is proposed to be extended from the south side of 70 Street to the Dodge
th
Nature Center property (see figure 4 in the appendix of this report). This service will provide water for
the Dodge Nature CenterÔs current and proposed expansion facilities.
REQUIRED EASEMENTS
At the intersection of 70 Street and Jamaica Avenue, where the roundabout is proposed,
th
additional right-of-way will be required at the four corners. The additional right-of-way will be
needed to construct the proposed trails. Temporary construction easements will also be required for
the proposed bypass lane and grading slope transitions.
RP
EQUIRED ERMITS
This project requires the following permits:
MPCA General Storm water permit (NPDES Permit)
Washington County Right of Way and Access Permit
MPCA Sanitary Sewer extension Permit
MN Department of Heath Water Main Permit
PROJECT COSTS
ECC
STIMATED ONSTRUCTION OSTS
A detailed cost estimate for improving Jamaica Avenue between Indian Boulevard and Military
Street South between 1600 feet west and 700 feet east of Jamaica Avenue, have
Road; and 70
th
been prepared and is included in the Appendix. All costs are based on anticipated unit prices for
the 2016 construction season, and they include an additional 30 percent for indirect costs
associated with the project. Costs for required right-of-way and temporary easements near the
intersection of Jamaica Avenue and 70 Street are not included. An overall summary of the
th
estimated cost is shown below:
Jamaica & 70 Roundabout $ 1,556,755

FINANCING
The improvement costs for this project would be financed through the use of a number of
dedicated funds and special assessments. Washington County would provide funding for a portion
of the improvements proposed within the 70 Street (C.S.A.H 22) right-of-way. Following is a
th
breakdown on the proposed project financing:
$ 1,615,177
Washington County
$ 2,097,511
City of Cottage Grove
$ 41,671
Dodge Nature Center
$ 57,400
Assessments*
$ 3,811,759
TOTAL PROJECT COSTS
*Assessment amounts were based on the City Policy
and benefit appraisals (see figure 5 in the appendix of
this report for assessable parcels). Based on the City
policy approximately $365,000 would be collected
through assessments ($245,800 for 6875 Jamaica
Avenue South, $119,200 for 7000 Jamaica Avenue
South). The benefit appraisal amounts received for
assessable parcels are less than the amounts
calculated through the CityÔs special assessment policy
($41,500 for 6875 Jamaica Avenue South, $15,900 for
7000 Jamaica Avenue South).
