About Pine Run Flood Retarding
The primary purpose of Pine Run Flood Retarding is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Upper Dublin Township (local government). It impounds the Pine Run.
The dam stands 21 feet tall and stretches 900 feet across, has a maximum storage capacity of 256 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2014, the structure is relatively new.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 12/24/2020.
