The purpose of this project is to develop a management plan to address the City of Alta’s stormwater runoff. Currently, there is no management plan and the city is growing, so there are increased runoff problems from both residential and industrial sources. A large assortment of pollutants flow from these areas, examples include various forms of sediment, paper, plastic, gravel and metal as well as less visible potentially toxic pollution from lawns, streets, gas stations and other commercial and industrial areas. The goal for this project is to construct two infiltration/detention basins to protect water quality and reduce the peak volume of the City of Alta’s urban runoff. Each basin is designed with two functions: Control gully erosion and surface erosion with detention, while incorporating water quality through infiltration. The downstream erosion control provided by detaining runoff will reduce sediment delivery to Powell Creek and protect downstream agricultural land from urban runoff. The infiltration features designed into the basins will capture pollutants commonly associated with urban stormwater runoff such as: sediment, sand, gravel hydrocarbons, particulate matter, heavy metals, and nutrients.
