Summary
With a height of 6 feet and a storage capacity of 32,900 acre-feet, this earth dam serves the primary purpose of tailings retention. Despite its relatively small size, P-4 poses a significant hazard potential and is classified as having a moderate risk level.
Constructed in an unnamed pond with a surface area of 5,483 square feet, P-4 is regulated by the state of Florida and undergoes regular inspections, permitting, and enforcement. It is situated in close proximity to the Jacksonville District of the US Army Corps of Engineers and falls under the jurisdiction of state agencies. The dam is not federally owned or funded, but its operations and maintenance are overseen by private owners.
Even though P-4's condition assessment is currently "Not Rated," the dam's risk management measures and emergency preparedness plans are yet to be fully evaluated. With a spillway type of "Uncontrolled" and no designated outlet gates, there is a need for further assessment and potential improvements to mitigate risks and ensure the safety of the surrounding community and environment. As water resource and climate enthusiasts, it is crucial to monitor P-4's condition and management practices to prevent any potential disasters and safeguard the local water resources.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
