Golden Meadows (Pine/Avon)Creating flood storage in the open space area of Golden Meadows Park in conjunction with the construction of relief sewers would significantly reduce the risk of flooding for the homes in the Pine Street/Avon Avenue. The goal of this project is to provide a location to safely hold stormwater while maintaining the existing recreational uses of the park.
To maximize playability of the fields, stormwater would not be diverted into the park unless the capacity of the existing storm sewer system is exceeded. Less frequent, non-flood causing events would not impact the park, as stormwater would bypass the area. During significant storm events, pipes would divert water away from the flood-prone areas and convey it into Golden Meadows Park. The park is designed to completely fill for the 100-year design storm event; stormwater would be held temporarily at the site and then drain by gravity to the existing storm sewer system. Period of inundation would be less than 24 hours.

Washington Street Stormwater Improvement Project
In an effort to further reduce the level of flooding on Washington Street, the City has purchased and removed 3 houses at 684, 688 and 692 S. Washington Street for the purpose of providing up to 3 acre-feet of stormwater detention. This detention, when combined with the on-going Madison Early Childhood Stormwater Improvement Project, will provide a total of 9.25 acre-feet of stormwater detention and will provide significant flood reductions benefits for residents on Bryan, Washington, and Euclid. The construction of this project will involve the installation of an underground pre-cast concrete vault by StormTrap, LLC. Work began in late March of 2017 and is scheduled to last 3-4 months.
Estimated Construction Start: March 2017
Estimated Construction Completion: Fall 2017
Estimated Budget: $1,264,330
Creating additional flood storage in the existing detention basin located south of Harrison Street, in conjunction with the construction of a relief sewer, would significantly reduce the risk of flooding for homes in Yorkfield Subdivision. The existing detention basin is a dry-bottomed facility with a capacity of approximately 8 acre-feet. During small storm events, a 1-cfs capacity pump station is utilized to drain the detention basin but during more significant storm events when the level of the basin rises, an overflow grate structure drains the basin by gravity to the pipe network to the south. The goal of this project is to improve the function of the existing drainage system by increasing both the capacity of the existing pipe system and the capacity of the existing detention basin. The proposed project involves the construction of a 36-inch diameter relief sewer from the low spot on Yorkfield Avenue to the Harrison Street detention basin. By replacing portions of the detention basin side slopes with retaining walls and excavating deeper, the storage volume of the facility can be increased by approximately 5 acre-feet. Since the existing detention basin relies on a pump station for dewatering, the deeper excavation will not change the outlet configuration of the facility. These improvements provide a 100-year level of protection for the homes within Yorkfield Subdivision.

Madison Early Childhood Education Center Stormwater Improvement Project
Creating flood storage in the open space area adjacent to the Madison Early Childhood Education Center would significantly reduce the risk of flooding for the Washington Street flood problem area in Southwest Elmhurst. The goal of this project is to provide a location to safely hold stormwater while maintaining the existing recreational uses of the school site.
Conceptual facility improvement plans were developed with the intent of creating flood storage while maintaining the existing soccer field in this location. To maximize playability of the fields, stormwater would not be diverted
Estimated Construction Completion: Spring 2017
