The Scott Blvd Dam, located in Johnson County, Iowa City, is a crucial structure designed by Stanley Consultants in 1980 for flood risk reduction along the S. Br. Ralston Creek. This earth dam stands at a height of 20 feet and stretches over 805 feet, providing a storage capacity of 313 acre-feet to help manage the surrounding drainage area of 1.42 square miles. With a spillway width of 4 feet and uncontrolled spillway type, the dam has been deemed to have a high hazard potential but is currently in satisfactory condition as of the last inspection in July 2020.

Despite its high hazard potential, the Scott Blvd Dam is well-maintained and regulated by the Iowa Department of Natural Resources, with regular inspections and enforcement measures in place to ensure its structural integrity and functionality. The dam serves as a vital flood risk reduction asset in the area, protecting the local community from potential water-related disasters. While it presents a moderate risk level, the dam's risk management measures are not explicitly outlined in the available data, indicating a need for further assessment and planning to enhance its resilience in the face of evolving climate challenges. Enthusiasts of water resources and climate resilience will find the Scott Blvd Dam an intriguing case study in infrastructure management and environmental protection efforts.
