North Crossing Regional Planning and Design
Waterloo, Iowa
Addendum No. 1
WHEREAS, City of Waterloo and Robinson Engineering Company entered into a contract dated April 5,
2021 for the design of the North Crossing Regional Planning and Design project in Waterloo, Iowa.
WHEREAS, City of Waterloo and Robinson Engineering Company desire to amend the previous
agreement to make the following revisions to the contract.
NOW THEREFORE, it is mutually agreed to amend the original Consultant Agreement as follows:
I. Scope of Services
The scope of services is amended to add the following scope items to the project:
Frontage Road Termination: Buckhart Street and the associated frontage road needed to be
removed to have enough room for an intersection design at Heath Street and Logan Avenue (US
Highway 63). This work will require several Iowa DOT permits, including a work in right-of-
way permit, entrance permits and a utility permit.
McDonalds site redesign: The McDonalds site was redesigned to function properly given the
proposed termination of the frontage road. This work includes the need for additional survey
information. Robinson Engineering staff met with the Franchisee and coordinated with the
Franchise Engineer to redesign the access to site after the frontage road is removed. Robinson
staff will provide the Franchise Engineer with a design concept for their review. The storm sewer
design will need to be reconfigured to move the site detention pond to a new location while
continuing to meet storm water requirements for this site. A new intersection between Buckhart
Street and Logan Avenue will need to be designed and coordinated with Franchisee Engineers
and city staff.
Extend Phillip Caldwell Drive: This task includes additional topographic survey of the area,
additional roadway design with the production of plan and profile sheets, and the design of all
utilities in this area with plan sheets. The regional grading model was extended to include this
additional area of coverage. An existing detention basin was designed to drain to the regional
detention basin.
Restructure Stormwater Conveyances: This task included design drainage swales through the
back yards of the commercial properties in the development to manage a portion of the 100-year
storm water flows. Design the streets and the underground storm sewer system to allow only the
front 50 to 100 feet of land to flow towards the streets. Design a number of different pipe outlets
to channel the swales and storm sewer system to the regional detention pond to meet the
stormwater management ordinance. Revised the detention pond calculations to match the new
system and evaluate any impacts these changes would have on the pond design. Make changes to
the pond as needed to accommodate the 100-year flows.

Lakeside Street Sanitary: The existing Lakeside Street sanitary sewer flows into the sewer
main along East 4th Street. This task will look at the system and make any changes to the flows to
ensure that it still drains into the 4th Street system.
Intersection at Heath Street and Logan Avenue: Although a subcontractor was tasked with the
design of signals for this intersection, some modifications had to be made. This task includes
making changes in the sidewalk and the intersection layout to provide room for the proposed
signals.
Final Platting and Right -of -Way Displays: This task will include the platting of North
Crossing 5th Addition in the area around Phillip Caldwell Drive. Platting work will be completed
by a subconsultant with a Licensed Surveyor on staff Right-of-way displays will be produced to
show impacts to property lines and proposed easements.
Construction Administration: This task will include the review of shop drawings during
construction by the design engineer only. Any additional construction needs will be outside of
this contract and need to be provided for elsewhere.
