Floodwaters caused about $1 million worth of damage and left behind piles of debris and muck when Issaquah and Tibbetts creeks overflowed in January, but the disaster also readied emergency planners for the next flood.
The next time flood waters rise, volunteers will fan out across flood-prone neighborhoods and city officials will unleash a deluge of information about water levels, road closures and recovery efforts. Many of the procedures were tested during what officials characterized as a successful response to the major flood in mid-January.
But the next flood could occur as early as the next several weeks, and officials said work remains to be done to prepare Issaquah for another natural disaster. On Oct. 27, City Council members received a briefing about the response to the January flood and preparation efforts for the upcoming flood season.
City Emergency Management Coordinator Steve Campbell said readings from a pair of flood gauges did not correlate with the damage caused by floodwaters. A U.S. Geological Survey gauge downstream on Issaquah Creek appeared inaccurate, Campbell said. The gauge indicated about 2,500 cubic feet per second, Campbell said, but flood damage was similar to the 3,500 cubic feet per second estimate from the last major flood to hit Issaquah, in 1996.

If the Green River swells from fall and winter rains, flooding could snarl traffic for Issaquah commuters, disrupt deliveries of food and fuel, and — a more remote possibility — cause local sewers to back up as floodwaters overwhelm the regional system.
Though the river winds through Auburn, Kent and Tukwila, the human and economic toll from flooding could reach Issaquah, emergency planners told City Council members Tuesday night. A Tukwila emergency planner offered a frank assessment of the potential impact of Green River floods.
Authorities expect the Green will flood because the U.S. Army Corps of Engineers will allow water to flow through the Howard Hanson Dam. The earthen abutment adjacent to the dam was weakened by severe weather last winter, and engineers worry the structure could fail if rain swelled the reservoir behind the dam. Read more

Amid talks about its 2009 budget, Eastside Fire & Rescue staff members recommended filling a new emergency coordinator position. But EFR’s commissioners chose to defer filling it, saying it isn’t necessary right now. Read more
