Springwood Stormwater Detention Dam

About Springwood Stormwater Detention Dam

The primary purpose of Springwood Stormwater Detention Dam 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 Kent City Public Works Dept (local government). It impounds the Soos Creek, Wetland 87 near Kent.

The dam stands 10 feet tall, creates a reservoir covering 7 acres, has a maximum storage capacity of 50 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1992, the structure is 34 years old.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/12/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
