2019/20 Low Point Drainage (Top O Hollow, 28th, and Kennedy) - City of Ames

This is the annual program for drainage improvements to decrease flooding at low points. Low point drainage improvements are not only focused on residential street locations, but specifically on those locations most in need of the improvements as affected by standing water, flooding, and insufficient pipe capacity. The program identifies core locations for improvements each year. In addition, improvements are made at miscellaneous locations identified throughout the year. During heavy rain, some areas become flooded, and damage to private property occasionally occurs. This program provides for installation of drainage improvements to decrease this flooding at low points. In 1994, the following criteria were established for evaluating and prioritizing drainage situations: 1) Potential damage from storm runoff; 2) Emergency vehicle access limitations created by runoff; 3) Number of people affected; 4) Number of structures affected; 5) Street classification; 6) Land use; and 7) Benefits of a project to adjacent areas. Based on these criteria, target areas for improvements are established. These improvements may include construction of detention areas, new pipe systems, and replacement systems to increase the ability to control the runoff so it can be carried by downstream systems. The 2019/20 scope includes Top O Hollow Road (1100 block), 28th Street (1100 block), and Kennedy Street (1100 block). The project was included in the city's 2019-2024 Capital Improvement Program (CIP). As of May 26, 2021, these 3 locations are still to be analyzed and are in the early process of determining what type of work will be included with the locations. Once that is done they will go for quotes or be incorporated with roadway projects. As of May 25, 2023, no new information available
