Business Park; and
WHEREAS, the Client and ATS now desire to enter into Supplemental Agreement No. 1 for the South
Business Park Platting and Final Design Services of roadway improvements along Ansborough
Avenue.
NOW THEREFORE, it is mutually agreed to amend the original Professional Service Agreement as
follows:
I. PROJECT DESCRIPTION
This project consists of the development of approximately 210 acres located in the southeast quadrant
of the Highway 20 interchange with Ansborough Avenue for the proposed South Business Park in
Waterloo, Iowa. The project will include grading, drainage, utilities, roadway and other construction
typical of a large -sale development. The development area includes approximately 182 acres zoned
Business Park (B-P) and 25 acres zoned Agriculture District (A-1).
The project includes recommended improvements to the Highway 20 westbound off -ramp and
Ansborough Avenue as proposed in the Traffic Impact Study, as well as the regional detention basin
improvements and a sanitary sewer extension from north of Highway 20 to the Business Park.
II. SCOPE OF SERVICES
The Scope of Services will encompass and include work, services, materials, personnel and supplies
necessary to provide platting and final design of improvements for the South Business Park Phase 1.
The Design Services will include topographic survey, concept design and grading plan development,
preparation of preliminary and final plats, final paving plans, to include improvements to Ansborough
Avenue and the Highway 20 westbound off -ramp extension, and off -site utility plans for sanitary sewer
and utility coordination to prepare easements for a natural gas main extension. Services will also
include assisting the City with a RISE grant application and coordination with stakeholders.
Phase 1 Final Design Services
The Scope of Services for the Phase 1 Final Design Services is further defined as follows:
Geotechnical Engineering and Environmental Review (Tasks 1 — 5)
Geotechnical Engineering (Tasks 1 — 2). The soil borings and geotechnical engineering activities will
be completed by Terracon Consultants. The scope of geotechnical engineering activities is intended to
provide the necessary design recommendations for the grading and paving of the project. The following
tasks are included in this scope:
Task 1 — Soil Borings. Soil borings will be obtained to determine the subsurface conditions in the
development. The number and depth of borings, as well as the number and type of samples obtained,
will be sufficient to complete the geotechnical engineering and recommendations for the project. It is
anticipated that 10 soil borings will be obtained along the proposed roadway and sanitary sewer
alignments at depths of 15 to 30 feet.

Task 2 — Geotechnical Engineering, Report, and Recommendations. The geotechnical engineering will
include the necessary laboratory testing, classifications, and geotechnical engineering analysis
required to develop the final geotechnical recommendations for the project, including subgrade
treatment recommendations, estimated shrinkage, and pavement thickness. Boring Location plan and
profiles will be developed.
Environmental Review (Tasks 3 — 5). These tasks will include environmental investigations required
to evaluate the presence of wetlands per US Army Corps of Engineers' requirements and to determine
if mitigation is required. If required, stream mitigation credits will be calculated. Additionally, an
assessment of potential habitat of federally and state protected species will be conducted. Stantec will
perform these tasks.
Task 3 — Wetland Boundary Delineation
Task 4 — Habitat Assessment
Task 5 — Stream Mitigation Determination
