(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 entered into Supplemental Agreement No. 1 on January 19, 2021 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; and WHEREAS, the Client and ATS now desire to enter into Supplemental Agreement No. 2 for construction- related services (CRS)for the 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 providing CRS 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 6600 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 is using State Revolving Fund (SRF)funding for this project. AECOM Technical Services (ATS) is providing engineering assistance to the City for the SRF process along with CRS. II. Scope of Services The Scope of Services will encompass and include detailed work, services, materials, equipment, personnel and supplies necessary to provide construction-related services for the Phase I project and associated engineering assistance to the City for the SRF process required for the project.
