Summary

Completed in 1960, this private earth dam stands at 14 feet high and spans 190 feet in length, providing flood risk reduction for the surrounding area. With a hazard potential rated as high and a moderate risk assessment, the dam is regulated and inspected by the Illinois Department of Natural Resources.

The dam, with a normal storage capacity of 6 acre-feet, plays a crucial role in managing water flow and reducing potential flooding in Cook County. Despite its age, the Brentwood Townehome Dam continues to stand as a key infrastructure for water resource management in the region. Although the condition assessment is not available, regular inspections and emergency action plans are in place to ensure the safety and functionality of the dam in case of unforeseen events.

With its strategic location and purposeful design, the Brentwood Townehome Dam stands as a testament to effective flood risk reduction efforts in Illinois. As climate change continues to impact water resources, structures like this play a crucial role in safeguarding communities and mitigating potential disasters. The dedication to maintaining and improving the dam showcases a commitment to sustainable water management practices in the face of evolving environmental challenges.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
