COUNCIL WORK SESSION AGENDA MEMO
To: Mayor, Councilmembers and City Administrator
From: John Powell, Public Works Director
Department: Engineering
Subject: CSAH 31 and CSAH 74 Corridor Study and Preliminary Engineering Update -
25 minutes
Meeting: Council Work Session - Jun 01 2026
INTRODUCTION:
In late 2024, Dakota County entered into an agreement with Alliant Engineering for the
preparation of a Corridor Study and Preliminary Engineering to include:
CSAH 31 (Denmark Avenue) from CSAH 50 to CSAH 74
CSAH 74 (220th Street) from CSAH 31 to Honeysuckle Lane
The county anticipates that this phase of the project will be completed by the end of June.
It is an appropriate time to update the City Council on this project.
It is anticipated that construction will primarily occur during the 2028 construction season.
DISCUSSION:
The original scope for this project included only CSAH 31; but as the county also wanted to
explore options for CSAH 74, and as it was contiguous, the county added an evaluation of
CSAH 74. As stated by Dakota County, the goals of study include the following:
Recommend pedestrian and bicycle crossing locations and improvements.
Evaluate intersection control types.
Develop a preferred design for a new Vermillion River bridge on Denmark Avenue
including a grade separated greenway trail connection.
Review the corridors for access, safety, speed management, and mobility
improvement opportunities.
Develop a layout to modernize the corridors with an urban section and
nonmotorized facilities.
Recommend stormwater management improvements.
The evaluation of the CSAH 74 road section was not pursued to the point of preliminary
design as it would have included extensive access management (driveway closures and
Page 2 of 5
consolidation). Combined with the fact that the CSAH 74 roadway pavement has life
remaining before reconstruction is necessary, the county shifted their focus to providing a
pedestrian trail along the north side of CSAH 74.
There has been extensive coordination with ISD 192 staff regarding the access locations
and the potential impact on traffic routing within the Boeckman Middle School site.
Staff will review the current corridor layout and some of the challenges related to specific
design features.
BUDGET IMPACT:
Dakota County does not yet have a project cost breakdown which identifies the City's cost
share on the project. Also, now that the payout is nearing completion, Staff can fully
evaluate the impact on city utilities resulting from the project.
