(one of two storm drains near WSB HQ, cleared, and receiving plenty of runoff/rainwater)
Another announcement just in from Seattle Public Utilities, with helpful info on what to do if this type of flooding turns up in your neighborhood – don’t wait for it to get to crisis level:

In anticipation of warming temperatures and continuing precipitation, Seattle Public Utilties (SPU) has activated its Urban Flood Response Plan — staging extra drainage crews and equipment throughout Seattle, and deploying storm observers to various at-risk sections of the city.

This afternoon’s decision to implement the city’s flood plan was purely precautionary, officials noted, and is intended to head-off potential problems before they develop. Calls from SPU customers asking for assistance with drainage issues have been light over the past 24 hours, with a total of only 14 calls recorded.

Under the flood plan, SPU’s 16 drainage truck crews drop their normal maintenance duties and stand by to field emergency calls. If the volume of calls becomes high enough, additional crews can be brought in from the SPU’s drinking water operations section and other areas of the Utilities.

To report flooding or blocked drains, please call (206) 386-1800.

Seattle Public Utilities has been asking for the public’s help in keeping Seattle’s 78,000 street drains — the city’s first line of defense against storms — free of snow and other debris. But only shovel that drain, SPU said, if you’re sure you can do it safely.

If you wondered the same thing one of our Twitter contacts wondered … we asked SPU if there is any online resource for locating the storm drain(s) nearest your house, and we just got the answer back: No. (Anecdotally, we can tell you they seem to be close to corners, so if you have to start somewhere, start there if you’re near one.)
