SUBJECT:PROFESSIONAL SERVICES AGREEMENT WITH FOTH INFRASTRUCTURE
& DESIGN, LLC FOR LINCOLN WAY CORRIDOR STUDY
COUNCIL ACTION FORM
BACKGROUND:
The Lincoln Way corridor between Grand Avenue and Duff Avenue is an extremely important
east-west route in Ames. This approximately half-mile segment serves downtown Ames,
nearby residential and commercial areas, Iowa State University-related travel, CyRide transit
stops, bicycle and pedestrian activity, and regional traffic passing through the community.
The Ames Area Metropolitan Planning Organization's (AAMPO's) long-range transportation
plan, Ames Connect 2050, identified the need to study this corridor because of its current and
projected traffic volumes, safety concerns, anticipated future development (including the LINC
development), and its importance as a multi-modal corridor.
The study is focused on developing future improvements in the corridor that will help
manage expected traffic flows, improve intersection levels of service, reduce crash
potential, incorporate multimodal facilities, and provide multiple options for managing
turning traffic along the corridor.
The study will include specific outreach to adjacent businesses to facilitate and
understand turning movements to help manage traffic queueing within the commercial
corridor. The study will also identify opportunities to prepare for the future
infrastructure improvements through reconstruction activities or redevelopment
activities such as the Linc project. As alternatives are developed and evaluated,
consideration will be given to maintaining business access and minimizing adverse
impacts to adjacent businesses and properties.
Funding for the study is available as follows:
Source Amount
AAMPO Federal Planning Funds $100,000
City of Ames 2026/27 Traffic System Capacity Improvements Program
(Road Use Tax Fund)$25,000
Total:$125,000
CONSULTANT SELECTION:
In accordance with federal and state procurement regulations governing the use of federal
MPO planning funds, the City issued a Request for Proposals (RFP) on January 8, 2026. Per
federal requirements, firms were not asked to submit fee information, ensuring a
1
qualifications-based selection process.
A selection team of City and AAMPO staff evaluated proposals using the following weighted
criteria:
RFP Scoring Criteria Points

2 HDR 94.3
3 Strand Associates 94.0
4 Olsson 88.3
5 Felsburg Holt & Ullevig 86.3
6 ISG 80.7
Based on these results, staff negotiated a professional services agreement with the
top-ranked firm, Foth Infrastructure & Design, LLC, for completion of the study.
PROJECT SCOPE:
Under the proposed agreement, Foth will provide transportation planning, traffic engineering,
and conceptual design services for the Lincoln Way corridor. The study area encompasses
Lincoln Way from Grand Avenue to Duff Avenue, with a focus on five intersections: Lincoln
Way at Grand Avenue, Clark Avenue, Kellogg Avenue, Duff Avenue, and a potential new or
modified intersection associated with the LINC development (see attached study area map).
Services will include:
Evaluation of existing traffic operations, safety conditions, vehicle speeds, access needs,
transit service, and bicycle and pedestrian facilities within the corridor.
Forecasting of future traffic volumes and assessment of the impacts of anticipated
development, including the LINC Development, for interim year 2035 and horizon year
2050.
Development of traffic models and operational analysis for existing, interim, and future
corridor conditions.
Evaluation of potential corridor and intersection configurations.
2
Assessment of multimodal needs based on existing conditions and recommendations
from Walk Bike Roll Ames.
Development of up to three detailed conceptual design alternatives, addressing roadway
geometry, pavement markings, traffic signal modifications, multimodal improvements,
utilities, drainage, and potential right-of-way needs.
Public engagement, including two digital surveys, outreach to local businesses,
developers, and property owners, and presentations to Ames City Council.
Preparation of a final report, design criteria memorandum, conceptual design exhibits,
intersection geometry sheets, and planning-level cost estimates for each concept.
The completed study will identify a preferred long-term improvement concept for the
corridor and provide the planning-level cost and implementation information needed to
guide future project development, capital planning, and funding decisions. The study is
scheduled for completion by June 2027.
ALTERNATIVES:
1. Approve the Professional Services Agreement with Foth Infrastructure & Design, LLC of
Cedar Rapids, Iowa for the Lincoln Way Corridor Study in an amount not to exceed
$125,000.
2. Direct staff to negotiate an agreement with the next highest ranked firm.
CITY MANAGER'S RECOMMENDED ACTION:
Lincoln Way is a critical corridor serving local and regional travel, downtown access, transit
stops, businesses, residents, and residents walking and biking. The segment between Grand
and Duff Avenue is particularly complex due to its traffic volumes, closely spaced
intersections, limited right-of-way, multimodal demands, and nearby development activity.
The proposed study will evaluate existing and future transportation needs and identify a
preferred concept for improving safety, mobility, and long-term corridor function. It will also
produce planning-level cost and implementation information to support future capital planning
and funding decisions.
Foth submitted the top-ranked proposal through the qualifications-based selection process,
and staff successfully negotiated an agreement within the available budget. Therefore, it is the
recommendation of the City Manager that the City Council adopt Alternative No. 1.

recommended improvements.
1. Traffic Data Collection
Most traffic data is available through the City, MPO, and Iowa DOT. The Consultant will
collect and organize the data for utilization in the analysis. The Consultant will identify and
collect any remaining data needed to complete the traffic analysis of the corridor. The
following Client data is available or can be collected by the Client:
• Continuous turning movement count data at the four traffic signals in the corridor
• Pedestrian push button actuations at the four traffic signals in the corridor
• StreetLight and Strava Metro data
• ADT counts and truck percentage
• Speed data
Additional data available through other sources includes:
• Iowa DOT ADT data
• CyRide bus stop and ridership data
• MPO travel demand model data
The consultant will collect video traffic data for the Lincoln Way at Clark Avenue and Lincoln
Way at Kellogg Avenue intersections to be used for near miss crash data analysis. In
addition, video traffic data will be collected by the consultant for the intersection of Lincoln
Way at Washington Avenue and processed for turning movement traffic volumes.
2. Traffic Review Meetings
The traffic review meetings with the Client will serve to establish schedules, promote a
dialog with the Client and other designated parties, improve the decision-making process,
11
Page 9 of 15
and expedite recommendation development. Prepare minutes of meetings and keep
documentation of other communications. For budget purposes, it is assumed three (3)
meetings will be held remotely by one (1) staff member of the Consultant.
3. Traffic Safety Analysis
The safety analysis shall review crash data in the corridor over the last five years from the
Iowa DOT ICAT program, identifying crash patterns and causes. We will utilize
methodologies from the Highway Safety Manual and the Iowa DOT’s Potential for Crash
Reduction (PCR) to identify potential causal factors and possible countermeasures. Our
team will review the 28 countermeasures and strategies of FHWA’s Proven Safety
Countermeasures Initiative (PSCI) that have proven effective at reducing roadway fatalities
and serious injuries. Lastly, traffic signage, pavement markings, and vehicle and pedestrian
traffic control will be reviewed.
4. Speed Study
The appropriate speed limit for the corridor will be determined using the methodologies in
NCHRP 17-76, FHWA USLIMITS2, and ITE Journal article A Model for Setting Credible Speed
Limits in Urban Areas. Eighty-fifth percentile speeds will be determined from data collected
by Client portable radar units. If needed, speed control measures will be explored.
5. Traffic Model Development & Analysis
The traffic model development and analysis shall incorporate, at a minimum, traffic
engineering principles and standards as presented in SUDAS, Client standards, and national
practices. While preparing the traffic model and analysis, the development of traffic
forecasts will follow the forecasting parameters agreed to by the Client.
a. Model Development
The Consultant will utilize the Synchro network template provided by the Client to
develop a base model of the existing corridor for the two highest peak hours using
2026 traffic data. Client provided information will be used to populate the model.
Additional models will be created in Synchro of the design alternatives for the two
highest peak hours using 2035 and 2050 traffic forecasted data. The Highway
Capacity Manual 7th Edition (HCM7) principles will be used to evaluate intersection
capacities.
b. Background Traffic Growth
The Consultant will work with the Ames Area Metropolitan Planning Organization
(AAMPO) to determine future background traffic growth for the project area.
c. Trip Generation and Distribution 2035
The Consultant will estimate the volume of traffic expected to be generated by the
proposed LINC Development with trip generation rate data published in the ITE Trip
Generation Manual, latest edition. The percentage of the LINC Development
assumed to be completed by 2035 will be determined in consultation with city staff.
Traffic will be generated for the weekday AM and PM peak hours. The new traffic
generation will be distributed to the study area intersections based on existing travel
patterns within the study area. The background traffic growth will be added to the
2026 traffic to get 2035 base traffic. The generated and distributed traffic will be
added to the 2035-year base traffic, and the new volumes will be used as the basis
for the 2035-year operational analysis. Forecasted corridor average daily traffic
(ADT) volumes will be determined using the provided traffic count data, forecasted
peak hour traffic volumes, and expansion factors.
d. 2050 Traffic Volume Forecasts
Traffic volumes will be forecasted to 2050 using the same procedure used for the
2035 trip generation and distribution. Background traffic will be added to the 2026
traffic to get 2050 base traffic. The generated and distributed trips will be added to
12
Page 10 of 15
the 2050 base traffic to establish the 2050 forecasted traffic volumes. It is assumed
that the LINC development will be 100 percent built out in this scenario.
e. Traffic Operational Analysis – Intersection Level
The Consultant will perform modeling and operational analysis of the project study
area. The modeling will be conducted to serve as a tool to graphically illustrate
future roadway improvements and impacts to traffic operation. This section shall
include the analysis of four (4) existing intersections and one (1) proposed
intersection within the study area as identified in the proposal and include:
• Lincoln Way at Grand Avenue
• Lincoln Way at Clark Avenue
• Lincoln Way at Proposed LINC Access/Washington Avenue
• Lincoln Way at Kellogg Avenue
• Lincoln Way at Duff Avenue
After receiving acceptance of the 2035 & 2050 forecasted traffic volumes from the
Client, the Consultant will analyze the study area intersections for the highest two
peak hours of a typical weekday for the following scenarios:
• Year 2026 – existing conditions
• Year 2035 – design alternatives
• Year 2050 – design alternatives
Design alternatives to be considered include the following cross sections on Lincoln
Way:
• Existing – No changes to the cross section but with potential changes to signal
timing/phasing.
• 3-lane section – one lane in each direction with a center two-way left-turn lane
o One alternative will look at signalized intersections
o One alternative will look at roundabouts for Lincoln Way at Grand
Avenue, Lincoln Way at Clark Avenue, and Lincoln Way at Kellogg
Avenue.
• 4-lane section with unbalanced lanes – one lane in one direction, two lanes in
the other direction, and a center two-way left-turn lane
• 4-lane section with median/access control – two lanes in each direction with
dedicated left-turn lanes at signalized intersections only.
• 5-lane section – two lane in each direction with a center two-way left-turn lane
Performance measures assessing the operation of the system will include delay,
volume to capacity ratio, operations of adjacent intersections, maximum
queue/storage lengths and control delay.
Recommendations on intersection geometrics, queue storage lengths, signal
phasing/timing and other improvements will be made as required to provide
acceptable service levels for major movements and the overall intersections.
6. Multimodal Review
The Consultant will consider the vision, goals, and content of the Walk Bike Roll Ames Bicycle
and Pedestrian Plan when considering options and developing design alternatives for
multimodal facilities within the corridor. The Consultant will review all pedestrian crossings
for safety and ADA/PROWAG compliance. The Consultant will look for opportunities to
improve the connectivity, consistency, and user friendliness of sidewalks and bicycle
facilities.
