Detention Tanks Safeguard Sammamish River, WLWB Exit Dangerous


In this image, notice the beginning of  the West Lake Sammamish Blvd. exit off of SR-520.  Do you see the beginnings of  light rail construction on the right?  The train will run right over the exit ramp. 

This exit was one of the most dangerous for me in Redmond for a while, especially at night.  The "fake" stop light, further down the sharp ramp was very misleading. Did this exit frighten you too?  Finally, it's fixed.

The video shows two points of interest.  

1)  As you drive east on SR-520, notice how close the rail is to the highway.  

2)  Orange stormwater detention tanks are densely massed together for a good reason; the Sammamish River is immediately below the filthy construction site.  Detention tanks "filter" contaminated sediment from construction runoff. 

Sound transit is a steward of our environment.

Why Detention Tanks:

Hard surfaces like pavement and roofs prevent precipitated runoffs from naturally seeping into the ground in developed areas. Instead, the water runoff makes its way into drains, sewer systems, and drainage ditches, carrying debris, chemicals, bacteria, eroded soil, and other pollutants. When this water pours in too quickly, it can cause underground systems like conduits and sewer lines to choke, leading to flooding, erosion, and turbidity. 

Additionally, your local council regulations ensure that the contaminated water at your property does not reach streams, rivers, lakes, and wetlands. Most new construction, be it commercial or residential, uses a water detention tank in their parking lots, open spaces, and backyards. On-site detention and drainage systems help manage accumulated water efficiently and follow environmental guidelines.
