The High Point Redevelopment Stormwater Dam in Seattle, Washington stands as a significant asset for flood risk reduction along Longfellow Creek.
Constructed in 2006 by SvR Design Company, this private dam serves a critical function in protecting the surrounding area from potential flood events. With a hydraulic height of 15.5 feet and a structural height of 15 feet, the dam provides essential storage capacity of 22 acre-feet to manage stormwater runoff effectively.
The dam's purpose is primarily flood risk reduction, with a high hazard potential due to its location and function. Despite this, the condition assessment as of August 2016 reported it as satisfactory, indicating that it is well-maintained and capable of meeting its intended purpose. The state-regulated dam is subject to inspections every five years to ensure its continued safety and functionality, with the last inspection taking place in August 2016. With its critical role in protecting the community from flooding, the High Point Redevelopment Stormwater Dam serves as a vital infrastructure asset in the region's water resource management and climate resilience efforts.
As climate change continues to impact weather patterns and increase the frequency of extreme weather events, the importance of well-designed and maintained stormwater infrastructure like the High Point Redevelopment Stormwater Dam cannot be overstated. With its strategic location along Longfellow Creek and its effective flood risk reduction capabilities, this private dam stands as a valuable resource in Seattle's efforts to mitigate the impacts of climate change on its water resources. As such, ongoing monitoring, maintenance, and regulatory oversight are essential to ensure the continued effectiveness and safety of this critical infrastructure asset.
