Summary

Owned privately, this stormwater pond is regulated by the MICHIGAN DEGLE and is subject to state permitting, inspection, and enforcement. Completed in 1970, this earth dam stands at a height of 17 feet and has a storage capacity of 660 acre-feet, serving a drainage area of 4.8 square miles.

With a high hazard potential and satisfactory condition assessment, Detroit Metro Airport Stormwater Pond 6 is equipped with a controlled spillway and a maximum discharge capacity of 46 cubic feet per second. Despite its critical flood risk reduction purpose, the pond's normal storage remains at zero, indicating its readiness to handle excess stormwater during extreme weather events. The risk assessment for this structure is rated as very high, further emphasizing the importance of its efficient operation and maintenance to safeguard the surrounding area from potential inundation.

In the event of an emergency, it is essential for the responsible parties to have an Emergency Action Plan (EAP) in place to ensure timely and effective response. Although details regarding the EAP preparation and adherence to guidelines are not specified in the data, the last EAP revision was recorded in June 2018. As the risk management measures and inundation maps for this stormwater pond remain undisclosed, ongoing monitoring, regular inspections, and adherence to safety protocols are vital to mitigate the identified risks and safeguard the Wayne County community from potential flood threats.

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.
