NOW THEREFORE, it is mutually agreed to amend the original Professional Services Agreement
as follows:
Project Description
The project consists of the following three elements:
1. Construction review services for the construction of the FY 2010 Lower Plaza,
extending from near the Waterloo Center for the Arts to Park Avenue. The Lower
Plaza project consists of enhanced pavement for the plaza and performance areas,
earthen levee relocation and retaining wall construction, amphitheatre and
associated limestone seating, infrastructure for Mark's Park, control buildings and
electrical service for the performance area, irrigation, landscaping and amenities for
the plaza, including lighting, benches and planters.
2. Additional construction review services for the Waterloo Dam and River Wall
Construction including work associated with the revised rock anchor system and
additional work elements associated with the 2007 and 2008 flood events.
3. Additional design elements for the Cedar Valley Riverfront Renaissance Waterloo
Vision Iowa Projects that have been completed since the final design scope was
written in January of 2005. The following items were completed as part of the
overall design for the project and were not anticipated at the time of the original
project development.
• Environmental Documentation. Documentation required for HUD Section 108
funding, including an Intensive Level Historic Survey and an Archaeological
Phase I Investigation.
• Federal and State Funding. Design and coordination efforts required for four
(4) of the Riverwalk Loop Projects upon receiving federal and state funding.
Iowa Department of Transportation requirements for design and specifications
were used on these projects, including appropriate submittals and coordination
with the funding agencies. The projects were required to follow the standard
federal and state aid process.
• Downtown Signage Review. Review conducted in conjunction with the Iowa
Department of Transportation completing new signage for the Highway 218 and
63 corridors. AECOM worked with City staff, design team members and the
Iowa DOT to determine location for signage, in addition to language for the
downtown destination signage.

• Upper Plaza Alternatives. Additional alternatives were reviewed for the
orientation of the Upper Plaza due to the pending adjacent private
development. Several alternatives were reviewed before arriving at the final
orientation.
• Right -of -Way Requirements. Due to the complexity of the R -O -W agreement
with US Bank, several additional design drawings were required during the
negotiation process, in addition to coordination and meeting time.
• Assistance with Drawings for Grant Applications. Additional drawings were
created during the project to assist in funding applications.
• Dam Re -Design. Due to the Karstic rock condition below the existing dam, the
rock anchors needed to be re -designed during construction.
• Additional River Wall Design. During final design of the projects, it was
determined rehabilitation of the existing north river wall downstream of the dam
was required. The design for this reconstruction was included in the river wall
construction project.
• Additional Enhancement Opportunities. Several additional enhancements were
included in the projects not known during the original scope of the project.
These included additional retaining walls that were required for several of the
projects, Rath letters to be incorporated in the trail system and Prairie
Pathways signage. In addition, overlooks in Paramount Park and 6th Street
were significantly expanded upon receiving additional funding for these
projects.
• Parking Configurations. Several parking configurations were reviewed in the
area of the Upper Plaza for City staff and design team reviews. These included
additional parking ramps, if needed, for the area in the future in addition to
potential parking arrangements with and without the future private
development.
• Additional Riverwalk Loop Design on 6`h Street from Washington Street to the
Levee. During the course of the final design for the project and the associated
economic stimulus funding received, the original project limits expanded to
include adding this section of recreational trail to the riverwalk loop to tie into
the US 218 trail system.
• Agency Coordination. Due to the sensitivity of the projects within the US Army
Corps of Engineers Local Flood Protection System and the flooding events in
recent years, additional scrutiny was placed on permitting for the projects.
Additional time was required for obtaining required permits.
• Additional Project Administration. Due to the required staging of the project,
delays caused by flooding, additional funding source requirements and
inclusion of the two related projects, the Cedar River Portages and Mark's
Park, the project has extended further than anticipated. Additional design team
and City staff meetings have been required. The original Vision Iowa Grant has
been extended two years to completion in 2011.

The above items summarize the major items not included in the original design scope. As
the project is an hourly not to exceed project, it was decided to see if the additional work
could be completed within the original contract budget. Based on the current project
standing, it is clear the additional work will not fit within the original budget.
An analysis was completed on the three projects for which design remains to allow letting
for construction bids — Riverwalk Loop from Mullan Avenue to Park, the Cattle Congress
Pump Station and the Upper Plaza. These three projects are currently in the design
process but require additional work for final construction document preparation. In addition
to these three projects, tasks have been included to update the web site with current
photos, project administration for project completion, and a task to complete design
elements required for the additional design elements in Mark's Park and the Performance
Structure as a part of the recent RECAT Grant.
The elements of Item 3 represent additional final design needs since the original
authorization on January 24, 2005. Review of the overall project budget for design and
construction -phase services supports that the additional design can be funded by a
reduction in the estimated construction -phase service fees so that the budget in total
remains as originally estimated.
The Scope of Services for these three project elements are further defined as follows:

weathered than borings had shown. The anchor system was redesigned to account for the
Karstic Limestone and additional time was required due to the revised installation
