Summary
Completed in 2008, this earth dam stands at a height of 18 feet and has a length of 165 feet, providing a storage capacity of 416 acre-feet. Its primary purpose is to mitigate potential flooding events in the region, with a satisfactory condition assessment as of April 2018.
Managed by the local government and regulated by the Arizona Department of Water Resources, this detention basin complex serves as a vital resource in preserving the safety and well-being of the surrounding community. With a high hazard potential and a moderate risk assessment rating, the complex is regularly inspected to ensure its continued effectiveness in managing floodwaters. The structure's location in Cochise County, Arizona, highlights its strategic importance in safeguarding the area from the impacts of extreme weather events.
Despite its uncontrolled spillway type, the Park Avenue Detention Basin Complex remains a stalwart defense against potential flood threats in the region. Its stone core and soil foundation, coupled with a surface area of 15.27 acres and a drainage area of 8.8 square miles, demonstrate its capacity to handle significant volumes of water during storm events. As climate change continues to impact water resources and weather patterns, this complex stands as a testament to proactive flood risk management and community resilience in the face of environmental challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
