(No paper) This paper describes an approach to the determination of flood frequency as a function of moneys that could be spent to address a road flooding problem caused by runoff from a 2-square-mile residential area near Washington, D.C. Flood mitigation options included both culvert resizing and the provision of detention areas upstream. Challenges faced in completing this project included establishing a practical limit on the number of detention sites to be considered, and right-of-way issues in an area fully developed for single family homes. The overall economic analysis was used by the county government to select a solution that was most desirable in terms of cost and benefit.
