Where's Rattlesnake Lake?
It's up a long hill outside of North Bend, WA. The center is run by Seattle Public Utilities. On the edge of a big watershed for Seattle's drinking water.
Why are the drums at the center?
Drums under downspouts to demonstrate water dripping off the roof over a long period of time. Less apt to flood. It was still gradually dripping on the sunny day I was there. Sounded like a "hippie drumming circle." That's what I thought it was.
Good idea, but how much will it add to the cost of construction?
How much land do all these catch basins take? Land is getting expensive.
Seems like a lot of trouble to slow the runoff from buildings. Why not just eliminate the parking lot? Impervious surfaces of pavement are terrible for runoff. Make people use alternative transit. Sure it's a change, but putting in all these roof gardens can be costly as well.
I hear that around 40% of the space in Los Angeles is devoted to pavement for parking and driving.
There is pavement that lets water soak into the ground below, rather than rush off.
There happens to be some of that pavement in my neighborhood. At the Whatcom Educational Credit Union.
Just ran out to take some images. Nice having a digital camera.
They've got the money.
I doubt this would work for heavily used thoroughfares and freeways. It would get beat up under traffic.
For parking lots? OK.
No problem for bicycle parking, of course. That's what I ride.
Autumn rainstorm after my trip. View of truck out my window.
