Summary

This private earth dam stands at 16 feet in height and spans 250 feet in length, providing a storage capacity of 44.8 acre-feet. While the dam's condition assessment is currently "Not Rated," its hazard potential is deemed significant, highlighting the importance of ongoing monitoring and maintenance to ensure its effectiveness in safeguarding the surrounding area from potential flooding events.

Despite not being regulated or permitted by the state, Kingstowne Bmp Basin #2 plays a vital role in mitigating flood risks in the region. With a primary purpose of flood risk reduction, this structure stands out as a key component in the local water resource management system. As the dam's last inspection date and condition assessment remain unreported, there is a need for continued oversight and evaluation to assess its performance and address any potential concerns that may arise.

Located within the jurisdiction of Fairfax County, this earth dam serves as a critical infrastructure for flood prevention along Dogue Creek. With no designated emergency action plan or risk assessment in place, there is an opportunity for stakeholders to enhance preparedness measures and ensure the resilience of Kingstowne Bmp Basin #2 in the face of evolving climate challenges. As water resource and climate enthusiasts, staying informed and engaged in the maintenance and monitoring of such essential structures is key to promoting sustainable water management practices and safeguarding communities from the impacts of flooding.

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.
