NOW THEREFORE, it is mutually agreed to amend the original Professional Services Agreement as
follows:
I. PROJECT DESCRIPTION
This project consists of improvements to the La Porte Road Corridor from just north of Mitchell
Avenue to the Shaulis Road intersection, including modifications to the existing traffic operations,
safety improvements, access management changes, transit accommodations, bike/pedestrian
facilities and corridor aesthetics.
The original design services have been split into three phases.
Phase I — Preliminary Engineering
Phase II — Final Design
Phase III — Construction -Related Services
This agreement is for additional Final Design Services on the La Porte Road Corridor from Shaulis
Road to Bopp Street and concept development of the Highway 20 and La Porte Road interchange
including traffic operations analyses.
II. SCOPE OF SERVICES
ADDITIONAL FINAL DESIGN SERVICES
Division 11— Final Design (Local Funding)
Final Design (Tasks 1-3)
These tasks include additional design modifications of the existing quadruple box culvert, culvert
railing, roadway lighting and additional project reviews and submittals. These tasks will be
completed by HR Green.
Task 1 — Structural and Railing Modifications (HR Green)
AECOM
Task 2 — Additional Lighting Modifications (HR Green)
Task 3 — Additional Project Reviews and Submittals(HR Green)
Division II — Local Funding
Highway 20 and La Porte Road Interchange Concept Development
Data Collection (Tasks 4-5)
Page 2
These tasks consist of collecting and reviewing data from the Iowa DOT and INRCOG for Highway
20, and available information from past studies and reports for the project location. It is anticipated
that AECOM will use the La Porte Road Traffic Analysis for the traffic data including volume data
(traffic forecasts, ADT, turning -movement counts, truck percentages, pedestrian and bicycle
counts, and speed studies), travel demand model and peak hour traffic forecast volumes, traffic
signal timing, as well as the Phase 1 design plans and aerial photography.
Task 4 — Data Collection
Task 5 — Review Data
Operational Analysis and Traffic Forecasting Memorandum (Tasks 6-9)
These tasks are to perform AM and PM peak hour level of service values for roadway links,
merge/diverge points, and intersections for existing, no -build, and proposed -build conditions.
Traffic forecasts will be developed using growth rates from the travel demand model provided by
INRCOG. Analyses will be completed using Highway Capacity Software (HCS) and/or Synchro.
AECOM will provide software outputs for analyses detailing performance factors including level of
service, total delay and 95th percentile queue lengths. AECOM will review queue lengths at ramp
terminal intersections and determine possible impacts to adjacent access points.
Task 6 — Traffic Forecasting and Coordination with INRCOG
Task 7 — Operational Analysis (One Alternative)
Task 8 — Queue Length Review
Task 9 — Operational Analysis and Traffic Forecasting Memorandum
Conceptual Interchange Exhibit (Task 10)
This task include development of conceptual roadway exhibits from aerial images and roadway
alignments. The proposed interchange exhibit will be developed at a concept planning level for one
alternative.
Task 10 — Conceptual Interchange Exhibit
Project Administration (Tasks 11-14)
These tasks include project administration, coordination and two review meetings with Iowa DOT,
City staff and AECOM, two project review meetings with City staff and AECOM, and quality control
review. The following identifies tasks leading to the completion of project administration, meetings
and coordination during this phase of the project.
Task 11 — Iowa DOT Meeting (2)
Task 12 — Project Administration
Task 13 — Project Review Meetings (2)
Task 14 — Quality Control Review
