RECOMMENDED ACTION: Motion to Approve the Scope of Service for TH 3 Corridor
Study— CSAH 42 to CSAH 46.
ISSUE
It is requested that Council consider authorizing the attached scope of service to conduct a corridor and
access study for TH 3 between CSAH 42 and CSAH 46 for a proposed fee of S18,250.
BACKGROUND
The attached scope of service is for a corridor and access plan along TH 3 between CSAH 42 and CSAH
46. It was developed in response to the land use planning study currently underway by the SUGAR task
force. Through recent discussions with MnDOT staff about the goals for evaluating future land uses
along this section of TH 3, there is value to completing a corridor and access plan concurrently with the
work of the SUGAR task force. The goal of this study is the identification and approval of future access
locations and configurations by MnDOT along the corridor. Developing a clear plan for the future access
locations will assist property owners and staff with development plans and memorialize decisions as land
uses are changed. The Plan would serve as the template for future development access, similar to the
County Road 42 Study.
The proposed scope has been reviewed by MnDOT staff and the schedule has been established to
coordinate with the SUGAR task force planning schedule.
Approximately S3,000 of remaining grant funding will be applied to the cost of the study with the balance
of the cost proposed to be funded by the Street CIP Fund.
SUMMARY
Staff recommends City Council approval of the attached scope of services.
TH 3 Corridor Study Proposal
CSAH 42 to CSAH 46
City of Rosemount, MN
PROJECT UNDERSTANDING
The City of Rosemount is currently working on a land use plan for the area west TH 3 between
CSAH 42 and CSAH 46. As part of finalizing the land use for the area access to TH 3 will be a
critical component. In order to determine the ideal access locations a planning level corridor study
should be completed.
The purpose of the TH 3 Corridor Study will be to:
1. Update the projected traffic volumes based on current and anticipated land use and traffic
growth.
2. Identify the future roadway cross section including lane configuration and right of way
needs.
3. Identify intersection access locations and control needs.
4. Prepare a capital improvement plan for the corridor including preliminary cost estimates and
anticipated improvement timeline.
The following outlines our anticipated scope of work for completing the study:
SCOPE OF WORK
1. Document Existing Traffic Conditions—WSB will collect the following data:
a. From MnDOT, County and City
• As built roadway plans.
• As built traffic signal plans and traffic signal timing plans for CSAH 42 and
CSAH 46.
• Access spacing guidelines
• UMore AUAR Scenario 2 traffic projections and analysis
• Historical traffic count date for the corridor
• Railroad crossing locations and data
• Anticipated land use plan
b. WSB staff
• 48 hour directional average daily traffic counts on the TH 3 at up to 4
locations
• AM and PM peak hour turning movement counts on TH 3 at:
1. CSAH 42
2. Canada Avenue
3. Canada Circle
4. CSAH 46
• 5 year crash history for the TH 3 corridor
TH 3 Corridor Study Proposal 1
2. Traffic Forecasts— Updated Projected 2030 ADT and turning movement counts will be
developed for the TH 3 corridor and each primary intersection. The projected traffic will
be based on the Met Council and Dakota County Regional Travel Demand Model, the
City's Transportation Plan, the UMore Scenario 2 traffic projections and historical
traffic count data.
3. Access Concept Plans—Based on current access guidelines, railroad crossing locations
and the anticipated land use plan for the area, access alternatives will be developed for
review and analysis. It is anticipated that up to 3 access plans will be prepared. The
layouts will include the intersection/access locations, corridor lane configuration,
intersection control, right of way needs and pedestrian accommodations. It is assumed
that existing aerial base mapping will be used to develop the concept layouts.
This task will also include preparation of a concept level cost estimate of the
improvements and an anticipated improvement timeline.
4. Traffic Operations Analysis—A weekday AM and PM peak hour peak hour traffic
operations and level of service analysis will be conducted for the TH 3 corridor and the
primary intersections using Synchro, a software package that implements Highway
Capacity Manual (HCM) methodologies. Output from Synchro is transferred to
SimTraffic, a micro-simulation computer modeling software that simulates each
individual vehicle's characteristics and driver behavior in response to traffic volumes,
intersection configuration, and signal operations. The model simulates drivers' behaviors
and responses to surrounding traffic flow as well as different vehicle types and speeds. It
outputs estimated vehicle delay and queue lengths at each intersection being analyzed.
The capacity and level of service analysis will be conducted for the existing 2014 and
projected 2030 traffic conditions. The analysis will document the corridor level of
service, intersection level of service, any operational deficiencies and recommendation
for intersection control and lane configuration improvements.
5. Report Preparation - WSB will prepare a summary report documenting the data
collection,traffic projections, traffic capacity analysis methodologies and
recommendations, concept layouts and the estimated improvement cost with an
anticipated timeline. WSB would submit a draft report to the City for their review. WSB
would then prepare a final report to incorporate any comments received from the City
and present the report to the City Council.
6. Meetings - WSB &Associates, Inc. would be available to attend any meetings that are
necessary to discuss or present the TH 3 Corridor Study. Five (5) meetings are assumed
at part of this proposal, one with City staff, one open house, two with the MnDOT and
County staff and one with City Council. If additional meetings are required, WSB would
bill those costs at our standard hourly rates.

ESTIMATED COST
The estimated cost to prepare the Corridor Study for Pinecone Road from 35th Street North to
County Road 120 is based on the above Scope of Work and is as follows:
Task Amount
Task 1 —Document Existing Traffic Conditions $2,200
Task 2—Traffic Forecasts $1,800
Task 3 —Access Concept Plans $7,750
Task 4—Traffic Operations Analysis $3,000
Task 5 —Report Preparation $1,300
Task 6—Meetings $2,200
Total Project Cost $18,250
WSB & Associates, Inc. will bill the City for the actual hours worked at each employee
classification times the current WSB hourly rates for that employee classification up to the
maximum not to exceed of$18,250.
