Summary

Owned by the local government, this earth dam was completed in 1989 and stands at a height of 28 feet, with a length of 410 feet. The pond has a storage capacity of 108 acre-feet and covers a surface area of 7.2 acres, providing critical protection for the surrounding area.

With a significant hazard potential, Northridge Swm Pond has been assessed as being in satisfactory condition as of April 2021. The dam features an uncontrolled spillway with a width of 84 feet, capable of handling a maximum discharge of 494 cubic feet per second. The structure is regularly inspected, with the last inspection taking place in April 2021, and has an inspection frequency of every 3 years. Additionally, the dam is regulated by the Maryland Dam Safety agency, ensuring its continued safety and functionality for the community.

Overall, Northridge Swm Pond plays a crucial role in mitigating flood risks in the region, offering moderate risk management measures and providing essential protection against potential inundation. With its strategic location and effective design, this pond stands as a testament to proactive water resource management and climate resilience efforts in Prince George's County, Maryland.

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.
