Development of a storm water utility for the City of Orem provided a funding mechanism to address storm water drainage, conveyance, and storage issues. Carollo assisted in the implementation of the storm sewer utility for the City of Orem. The project included coordinating the work efforts of the Citizen’s Advisory Committee and the City Council in formulation of the utility. This project also included developing the single-family residential equivalent service unit and providing the impervious surface area measurement for nonresidential properties.
