Summary

Designed by Christopher Consultants, this earth dam stands at a height of 18 feet and serves the primary purpose of flood risk reduction for the Plumtree Branch-TR. Completed in 2015, this structure has a storage capacity of 0.24 acre-feet and covers a surface area of 0.13 acres.

With a significant hazard potential and a high risk assessment rating, the Lutheran Village At Millers Grant Pond 1 dam is inspected regularly to ensure its structural integrity and safety. The condition assessment conducted in July 2018 deemed the dam to be satisfactory, providing some assurance to the surrounding community. While it does not have a spillway, this dam plays a crucial role in managing flood risks in the area and is regulated by the Maryland Dam Safety agency.

Overall, the Lutheran Village At Millers Grant Pond 1 dam stands as a vital asset in flood risk reduction efforts in Howard County, Maryland. With its strategic location and effective design, this private earth dam contributes to the safety and protection of nearby residents and properties, highlighting the importance of responsible water resource management in the face of climate variability and changing precipitation patterns.

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.
