Summary

Completed in 2008, this earth dam stands at a structural height of 35 feet and has a storage capacity of 4900 acre-feet. The dam is under state regulation by the North Carolina Department of Environmental Quality and the Dam Safety Program, ensuring its compliance with safety standards.

With a high hazard potential and fair condition assessment, the Pcs Phosphates R-5 Dike is regularly inspected to maintain its integrity. The last inspection was conducted in February 2020, with a frequency of every two years. The dam serves a primary purpose of "Other" and falls under the dam type of "Earth," highlighting its importance in water resource management and climate resilience efforts in the region.

Managed by a combination of state and federal agencies, including the Wilmington District of the US Army Corps of Engineers, the Pcs Phosphates R-5 Dike plays a critical role in flood control and water storage. With its strategic location and capacity, this dam serves as a vital infrastructure asset in Beaufort, North Carolina, contributing to the overall environmental and water resource management efforts in the area.

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.
