CITY OF WATERLOO, IOWA
US HIGHWAY 63 SOUTH INTERCEPTOR SEWER UPGRADE
US HIGHWAY 63 PHASE I AND HOME PARK BOULEVARD
SANITARY SEWER IMPROVEMENTS
SUPPLEMENTAL AGREEMENT NO. 1
WHEREAS, a Professional Services Agreement was entered into between the City of Waterloo (Client),
715 Mulberry Street, Waterloo, Iowa, and AECOM Technical Services, Inc. (ATS), 501 Sycamore Street,
Suite 222, Waterloo, Iowa, dated July 13, 2020, for a Phase I Preliminary Engineering Report for a new
interceptor sewer serving the Highway 63 south corridor; and
WHEREAS, the Client and ATS now desire to enter into Supplemental Agreement No. 1 for final design
and preparing plans, specifications and contract documents for the US Highway 63 Phase I sanitary sewer
and the relief sewer from the Home Park Boulevard neighborhood.
NOW THEREFORE, it is mutually agreed to amend the original Professional Service Agreement as follows:
I. PROJECT DESCRIPTION
In recent years, there has been a large amount of growth along the US Highway 63 corridor in the
south part of Waterloo. The sanitary sewer flows generated by this development have increased
causing the existing sanitary sewer lines undersized to handle flows during large storm events.
Also, the Home Park Boulevard neighborhood has experienced high sanitary flows with basement
backups last summer during large storm events. The intent of this project is to upgrade and
increase the capacity of the sanitary sewer along US Highway 63 and provide a relief sewer from
the Home Park Boulevard neighborhood to help mitigate backups during periods of high flow. The
sanitary sewer upgrades along US Highway 63 are planned to be completed in three phases. This
agreement covers Phase I of the upgrade and the relief sewer from the Home Park Boulevard
neighborhood.
The project consists of preparing plans, specifications and contract documents for the US Highway
63 Phase I sanitary sewer and the relief sewer from the Home Park Boulevard neighborhood. The
Phase I sanitary sewer upgrade is about 6400 LF. Phase I of the US Highway 63 sanitary sewer
upgrade extends from approximately Home Park Boulevard to Jane Street. The proposed relief
sewer from Home Park Boulevard is approximately 1500 LF. This relief sewer will start at the
intersection of Home Park Boulevard and Fletcher Avenue and tie into the US Highway 63 sanitary
sewer. This project provides numerous benefits for economic development along the US Highway
63 corridor and improves flow conditions in a portion of the system which currently experiences
overloading during wet-weather flows.
The City would like to obtain a State Revolving Fund (SRF)loan for the construction of this project.
Obtaining the loan is a multi-step process that requires the input of the City, Iowa Department of
Natural Resources (Iowa DNR) and the design engineer. Each entity has various responsibilities
at various stages of the loan acquisition process. AECOM Technical Services (ATS) will provide
engineering assistance to the City for the SRF process.
II. SCOPE OF SERVICES
The Scope of Services to be performed shall be completed in accordance with generally accepted
standards of practice. ATS will utilize the Statewide Urban Design and Specifications (SUDAS)
and engineer-provided technical specifications for this project, along with any applicable standards
and technical modifications by Waste Management Services Department (WMSD). The Scope of
Services is further defined by the following tasks:
�L=C0m Page 2
Phase I - Design and Bidding Phase Services
Task 1 - Project Management Progress Meetings/Kickoff Meeting. With WMSD and ATS staff, a
kickoff meeting will be conducted to discuss scope of project, objectives and goals. ATS staff will
also attend progress meetings, as needed, where updates on the project design will be presented
to WMSD staff.
Task 2 - Survey and Data Collection. ATS will acquire available data about the locations for the
proposed sanitary sewer along US Highway 63 corridor and for the proposed relief sewer from
Home Park Boulevard and Fletcher Avenue to US Highway 63. This will include gathering aerial
photography, available topographic data and utility location mapping information to develop a base
map of the project location. ATS will establish horizontal and vertical control and perform a
topographic survey for the project area. "One Call"will be contacted to locate utilities. Marked field
locations of utilities will be surveyed.
Task 3 - Obtain Soil Borings. ATS will propose locations for soil borings along the route of the
proposed US Highway 63 sanitary sewer and proposed relief sewer from the Home Park Boulevard
area. ATS will work with a professional geotechnical firm to conduct the soil borings and provide a
geotechnical report of the findings. Terracon Consultants will complete the geotechnical work for
this project.
Task 4 - Right-of-Way Review. ATS will review City, county and state records pertaining to the
survey corridor. Property lines, right-of-way lines and ownership of properties will be incorporated
into the base mapping for the project. It is assumed that the proposed US Highway 63 sanitary
sewer and relief sewer from Home Park Boulevard will be in the existing right-of-way.
There are five temporary construction easements anticipated for this project. ATS will prepare
needed temporary construction easement drawings for this project. Permanent acquisition plats
are not anticipated.
Task 5-Preliminary Design Drawings. Drawings will be developed showing base mapping,existing
site features, known utilities, proposed sanitary sewer locations and existing ground contours. The
following design details are unique to this project and are to be included:
a. This project will need to be coordinated to provide continuous service (bypass pumping) of
the collection system during construction. Temporary diversion of wastewater around the
area under construction will likely be required during some periods of construction.
Information for temporary diversion of wastewater will be included in the design.
b. Sizing of sanitary sewer pipes are to be based on sanitary sewer computer flow modeling
completed in 2020 for this project.
Task 6 - Plan and Profile Sheets. Preliminary plan and profile sheets will be prepared for the
sanitary sewer installations.
Task 7- Preliminary Design Meeting. ATS will meet with WMSD and review a preliminary plan set.
Key design items will be discussed; and based on feedback, a list of alterations will be made for
the final design.
Task 8 - Final Plans and Specifications. Final plans and specifications will be developed
incorporating comments received by WMSD. Plans will include cover sheet,general notes,sanitary
sewer plan and profile sheets and details as necessary. Specifications will include contract
documents incorporating requirements from WMSD. SUDAS specifications will be referenced,
along with engineer-provided technical specifications as needed.
