Summary

2, located in Beverly Hills, California, is a vital water supply structure managed by the local government. This earth dam, completed in 1982, stands at a height of 49 feet and has a storage capacity of 206 acre-feet. Situated on the Franklin Canyon stream, this dam serves the primary purpose of water supply for the region, showcasing its importance in sustaining the local water resources.

Maintained and regulated by the California Department of Water Resources (DWR) under the Safety of Dams program, Lower Franklin No. 2 has been deemed to have a low hazard potential and is in satisfactory condition as of the last assessment in 2017. With state-permitting, inspection, and enforcement protocols in place, this dam plays a crucial role in ensuring the resilience of the water infrastructure in Los Angeles County. The structure's compliance with safety standards and regular inspections further underscore its significance in water resource management.

Despite its modest surface area of 10 acres and a drainage area of 1.12 square miles, Lower Franklin No. 2 stands as a reliable asset in the region's water supply network. With its strategic location and functional design, this dam continues to contribute to the sustainable management of water resources in the area, highlighting the collaboration between local government agencies and state regulators in safeguarding vital infrastructure for the benefit of the community and the environment.

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.
