Summary

Completed in 1998, this earth dam stands at a height of 6.5 feet and has a storage capacity of 34 acre-feet, serving as a crucial line of defense against potential flooding in the area. The dam is regulated by the Pennsylvania Department of Environmental Protection, ensuring that it meets state standards for inspection, enforcement, and permitting.

With a high hazard potential but a satisfactory condition assessment, Cedar Crest Boulevard dam plays a crucial role in safeguarding the surrounding community from potential flood events. The structure is continuously monitored through regular inspections, with the last one conducted in January 2021, to ensure its integrity and functionality in times of need. While specific risk management measures and emergency preparedness details are still pending, the dam's design and purpose underscore its importance in mitigating flood risks and protecting the local environment and residents.

As an essential flood risk reduction infrastructure in Lehigh County, Pennsylvania, Cedar Crest Boulevard stands as a testament to the proactive measures taken to safeguard against natural disasters. Managed by local government authorities and regulated by state agencies, the dam's presence underscores the ongoing efforts to protect communities and water resources from the impacts of extreme weather events and climate change. With its strategic location and functional design, Cedar Crest Boulevard remains a critical asset in the region's overall resilience to potential flooding and water resource management challenges.

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.
