Van Milligen, City Manager SUBJECT: Water System Improvements 2024 North English Road Water Main Extension Project — Receipt and Consideration of Bids DATE: August 28, 2025 Water Department Director Christopher Lester is sharing information on the bids for the Water System Improvements — 2024 North English Road Water Main Extension project. The City of Dubuque's Water Department has identified a phased capital improvement program to extend and make necessary improvements throughout the community. The improvements are primarily associated with the water distribution system. These improvements will address water resiliency, reduce bottlenecks, improve water storage and pumping at key locations throughout the community to support the existing customer base and prepare the city for increased demands associated with existing and new customers. The improvements will also assist the City's need to reduce and better manage dead-end water mains and other areas where the water age and water quality can suffer due to lack of circulation. In 2022, Origin Design was awarded the City -Wide Water Distribution System, Storage, and Pumping Improvements Project and completed the preliminary design identifying five (5) capital projects. One of the five projects is the North English Road Water Main Extension project that will bring water service to a portion of the SW Arterial, starting at Edval Lane and N. Cascade Road, west along the SW Arterial to North English Road. This project will allow continued extensions, looping water main along the SW Arterial between USHWY 151/61 to USHWY 20 while also providing service between pressure zones and increasing water service reliance to the city's southern and western most customers. This project has been awarded funding through the Iowa State Revolving Fund (SRF) program and was originally advertised for bids on June 18, 2025. Following a design modification to upsize the water main along North English Road from 12 inches to 16 inches, an addendum and revised Notice to Bidders were required. As a result, a new public hearing date was scheduled for August 18, 2025. The revised Notice to Bidders was posted on the City of Dubuque website and the Construction Update Plan Room on July 22, 2025. Page 156 of 629 Sealed bids for the Water System Improvements — 2024 North English Road Water Main Extension project were received and publicly opened on August 21, 2025.

BACKGROUND The City of Dubuque's Water Department has identified a phased capital improvement program to extend and make necessary improvements throughout the community. The improvements are primarily associated with the water distribution system. These improvements will address water resiliency, reduce bottlenecks, improve water storage and pumping at key locations throughout the community to support the existing customer base and prepare the city for increased demands associated with existing and new customers. The improvements will also assist the City's need to reduce and better manage dead-end water mains and other areas where the water age and water quality can suffer due to lack of circulation. In 2022, Origin Design was awarded the City -Wide Water Distribution System, Storage, and Pumping Improvements Project and completed the preliminary design identifying five (5) capital projects. One of the five projects is the North English Road Water Main Extension project that will bring water service to a portion of the SW Arterial, starting at Edval Lane and N. Cascade Road, west along the SW Arterial to North English Road. This project will allow continued extensions, looping water main along the SW Arterial between USHWY 151/61 to USHWY 20 while also providing service between pressure zones and increasing water service reliance to the city's southern and western most customers. Origin also prepared and assisted the City in securing an Iowa SRF loan for the proposed improvements, and a Planning and Design Loan. DISCUSSION Origin Design has completed the plans and specifications for the installation of a 12-inch water main extension, beginning at Edval Lane on North Cascade Road and extending south to the Southwest Arterial. At the intersection with the Southwest Arterial, the main increases to Page 158 of 629 16 inches in diameter and continues west to North English Mill Road, where it turns north and extends approximately 1,100 feet along North English Road. The North English Road water main extension creates a path for a future loop and connection of Pressure Zone 3 and 4, when in later phases it can extend to English Mill Road and then south to the English Mill Pump Station. This project has been awarded funding through the Iowa State Revolving Fund (SRF) program and was originally advertised for bids on June 18, 2025. Following a design modification to upsize the water main along North English Road from 12 inches to 16 inches, an addendum and revised Notice to Bidders were required. As a result, a new public hearing date was scheduled for August 18, 2025. The revised Notice to Bidders was posted on the City of Dubuque website and the Construction Update Plan Room on July 22, 2025. Sealed bids for the Water System Improvements — 2024 North English Road Water Main Extension project were received and publicly opened on August 21, 2025. Top Grade Excavating, Inc, of Farley, Iowa submitted the apparent low bid in the amount of $1,478,135.00.
