THE CITY OF <br /> CITY COUNCIL AGENDA REPORT <br /> pi .-EASANTON <br /> January 18, 2022 <br /> Operations Services <br /> TITLE: APPROVE A PROFESSIONAL SERVICES AGREEMENT WITH <br /> WOODARD AND CURRAN FOR THE NOT-TO-EXCEED AMOUNT OF <br /> $509,227 FOR DEVELOPMENT OF THE SEWER COLLECTION SYSTEM <br /> HYDRAULIC MODEL, CAPACITY EVALUATION AND RELATED <br /> STUDIES, CIP NO. 16245 <br /> SUMMARY <br /> The City Sewer Utility collection system includes 252 miles of pipe, 11 lift stations, and <br /> eight siphons. The complex nature of the collection system makes it necessary to use <br /> computer modeling to accurately assess the system capacity and performance. In this <br /> project staff is proposing to develop a hydraulic model of the collection system. The City <br /> last developed a similar hydraulic model in 2007, however, since then modeling <br /> technology has advanced and there have been significant changes in the collection <br /> system configuration necessitating the need for a new model. This project is included in <br /> the City Council Priorities Work Plan. <br /> Once the new model has been developed and calibrated, it will be used to evaluate the <br /> capacity of the City's existing sewer system. If warranted, capital improvement projects <br /> will be recommended to address capacity shortfalls within the system. The model will <br /> also be used to identify infrastructure improvements needed to meet future growth, <br /> evaluate new or improved operational strategies, and assess the impacts of unique <br /> development projects. <br /> Staff recommends award of a contract to Woodard & Curran, Inc. to develop a working <br /> GIS-based hydraulic model, conduct a capacity evaluation of the existing system and <br /> conduct other related studies. <br /> RECOMMENDATION <br /> Approve and authorize the City Manager to execute a professional services agreement <br /> with Woodard & Curran for development of a hydraulic model, capacity evaluation and <br /> related studies, for a not-to-exceed amount of $509,227. <br /> FINANCIAL STATEMENT <br /> The anticipated total expenditure for this project is $509,227, which includes a 10 <br /> percent contingency of $46,293 for unforeseen circumstances and related extra <br /> services as determined to be necessary by the City. Current funding for the project is <br /> available from the Sewer Capacity Evaluation Project, CIP No. 16245. <br />
