I. PROJECT DESCRIPTION
The Sunnyside Creek Improvement Project involves construction of a wet detention pond located
between Highway 20 and West San Marnan Drive, generally centered on the main channel of
Sunnyside Creek. The project also includes bank channel stabilization of approximately 1,050 feet
of the existing Sunnyside Creek channel located downstream of the proposed basin (between San
Marnan Drive and Westchester Drive).
According to the Black Hawk County Flood Insurance Study (FIS) and the effective Flood Insurance
Rate Maps (FIRMs) for Black Hawk County, the project is located in a Zone A floodplain, which
means the 100-year floodplain was developed based on approximate methods and a detailed
analysis resulting in base flood elevation determinations has not been completed. As part of this
project, a detailed analysis will be completed for the wet detention basin design and required
regulatory permitting.
This supplemental agreement will include development of the full grant application package for the
IDALS Water Quality Initiative for Urban Conservation Projects. AECOM and the City of Waterloo
submitted a pre -application package for the above referenced grant application on November 16,
2023, and was notified on December 15, 2023 that the pre -application package was selected to
move forward with the full application.
II. SCOPE OF SERVICES
The Scope of Services for this supplemental agreement will encompass and include detailed work,
services, materials, equipment, personnel and supplies necessary to complete the full grant
application package to IDALS on or before Friday, February 9, 2024 at 4:30 pm.
