BACKGROUND:
On June 16, 2015, the Rosemount City Council received the Feasibility Report for the Danbury Way
Improvements Project, City Project 453. Staff will present a brief overview of the project and respond to
questions that Council members or the public may have regarding the proposed improvements or
assessments.
A summary of the proposed improvements and estimated project cost and funding is provided below.
Proposed Improvements
The Danbury Way Improvement Project is proposed to include the reconstruction of approximately 6300
feet of roadway. The project is proposed to include the following:
• Removal and replacement of the existing subgrade and pavement.
• Installation of surmountable concrete curb and gutter
• Installation of storm sewer at low points in roadway
• Establish an outlet to a pond along the south side of McAndrews Road.
Options Evaluated
Pavement Type:
At the request of Council, concrete pavement and bituminous pavement were evaluated with the
feasibility report. Bituminous pavement is recommended for the following reasons.
• Easier access during construction
• Lower upfront construction costs, $500,000 cheaper than concrete pavement
• Easier to patch and repair compared to concrete pavement
Roadway Improvements:
At the request of property owners, the installation of ditches was reviewed. Ditches are not proposed
due to the large amount of tree removals required.
Stormwater Quality Improvements:
Additional stormwater quality improvements can be completed to improve water quality in the existing
wetlands. If water quality improvements are desired, the recommended option is the installation of
sedimentation structures at the two main low points on the roadway. One sedimentation structure
could be installed at each low point for an additional cost of $100,000.
Fiber Installation:
At the request of several residents, the City obtained an estimate from Frontier Communications to
install fiber optic cable along the length of Danbury Way. The estimated cost is $257,250. Due to the
high cost of installation, fiber is not included with the proposed improvements.
3
Schedule
It is proposed that construction begin in June, 2016 and is anticipated to be completed, including all
restoration items, by fall, 2016.
Public Informational Meeting
Prior to the public improvement hearing, staff hosted three public informational meetings on the dates
listed below. The meetings provided a background on the project costs and scope gave property owners
the opportunity to address questions and comments regarding the project and proposed assessments.
Public comments from the two recent meets are recorded and are included in the feasibility report.
• December 20, 2006
• September 26, 2013
• March 12, 2015
