Summary

Constructed in 1982 by Purdum and Jeschke Consulting Engineers, this earth dam stands at 15 feet high and spans 1200 feet in length. With a drainage area of 4.51 square miles, the levee plays a vital role in protecting the surrounding area from potential water hazards.

Despite its fair condition assessment, the Roland Run Levee is deemed to have a high hazard potential due to its location and the volume of water it manages. The dam is regulated by the Maryland Dam Safety agency, ensuring that it meets all necessary standards for inspection, permitting, and enforcement. With a high risk assessment rating, the Roland Run Levee is closely monitored to mitigate any potential threats and ensure the safety of nearby communities in Essex Farms.

As a local government-owned structure, the Roland Run Levee remains a critical component of water resource management and climate resilience in the region. With its strategic placement and design, this levee continues to safeguard against flooding and protect the environment and residents along the Roland Run stream.

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.
