Mayor outlines Seattle’s winter storm preparedness efforts

FOR IMMEDIATE RELEASE: 11/1/2012

Mayor outlines Seattle’s winter storm preparedness efforts
Describes online tools available to help public prepare for winter weather

SEATTLE – Mayor Mike McGinn today encouraged residents to begin making annual preparations for the possibility of winter weather-related emergencies and updated the public on how the City is preparing for winter storms. McGinn described online tools available to the public to help them track storms and their impact on City services. He also described efforts the City is taking to help support storm recovery on the East Coast.

“Whether it’s heavy rain, snow and ice, or strong winds, winter weather can cause significant disruption to our lives and our economy. Now is the time to start to prepare for storms, and the City is here to help support the public as they get ready for winter,” McGinn said.

McGinn also described online tools available to the public to help them prepare and cope with winter weather. Seattle Public Utilities’ Rainwatch program – developed in partnership with UW meteorologists Cliff Mass and Phil Regulski – tracks storms and forecasts rain at the neighborhood level, providing the region’s most accurate and precise weather tracking and forecasting system. Our program Snowwatch uses data from Rainwatch, combined with temperature trends, to estimate and predict snowfall. Seattle City Light’s Windwatch provides the same function for forecasting of high winds, and their Outage Map tracks power outages across Seattle. McGinn also highlighted the Seattle Department of Transportation’s Winter Weather Response Map, which helps residents plan trips based on traffic cameras and real-time information about where our snow ploys are deployed.

“The single biggest thing that Seattleites can do to help prevent urban flooding is to clean leaves out of street drains,” said Seattle Public Utilities director Ray Hoffman.

There are several ways that residents can help their families and the City respond to disruptions, including loss of power, during winter storms:

• Residents should always have a three-day supply of water and food that does not need to be cooked;
• Have extra blankets on hand and close the doors to rooms you aren’t using to help keep warm;
• Don’t bring your barbecue or any fossil fuel burning stove inside your house to cook when the power goes out – this could cause carbon monoxide poisoning;
• A hand-crank radio and a hand-crank flashlight should be available – please don’t use open flames such as candles;
• The City of Seattle is a partner in the regional Take Winter By Storm effort – residents are encouraged to visit www.takewinterbystorm.org for more tips on being prepared for winter;
• Call 206-684-7400 to report a power outage, to find out about reported outages and to asked to have call-back when your power is restored. Seattle City Light needs your current phone number – both home and cell – in order to respond to your call.

Complete checklists are available at www.takewinterbystorm.org. Tips for what to do when the power goes out are available at https://seattle.gov/light/neighborhoods/nh4_pout.htm.

In the event of snow and ice, the Seattle Department of Transportation has 30 snowplows of various sizes and configurations, 10 plow only trucks for use during heavy accumulation, and 4 anti-icing vehicles available. They have trained an operator pool within the City utilities and parks departments to cover all shifts. SDOT currently have 3,800 tons of granular salt & 47,000 gallons anti-icing storage capacity, roughly three times more granular salt storage than last season. 11 new roadway surface temperature sensors have been purchased and are being installed to help SDOT improve their ability to deploy resources as needed.

In addition to helping Seattle City Light customers prepare themselves for power outages, in the six years since the December 2006 windstorm that knocked out half of their distribution system, City Light has reorganized its storm response procedures. They have installed a computerized outage management system to coordinate restoration work and customer communications; and increased tree trimming to avoid outages from branches coming into contact with power lines. In 2012, City Light cleared more than 600 line miles of trees from power lines. Since 2007 the utility has cleared 2375 line miles. Since 2007, City Light has added 100 line workers and re-instated their apprenticeship programs.

“Our crews are ready to respond and restore service as quickly and as safely as possible, but it is always important for each of us to be prepared for a power outage,” Seattle City Light Superintendent Jorge Carrasco said.

Seattle Public Utilities crews work year round to get ready for storm season. By the end of this summer, the crews had pumped out over 4,300 catch basins and inspected over 25,000. They had inspected 85 miles of pipes and cleaned more than 164 miles of pipes.

SPU is also preparing its Urban Flood Response Plan. When activated, the utility puts field crews on alert, and stages flood control equipment at various locations around the city. SPU deploys volunteer storm observers to monitor various flood-prone areas, freeing up crews to do the work they need to do such as clearing drains. Regular City crews can be called in if needed for assistance.

Are You Prepared for Landslides?

FOR IMMEDIATE RELEASE: 10/30/2012

Are You Prepared for Landslides?
Rainfall gauge exceeds landslide threshold

SEATTLE — Did you know that most landslides occur between the months of October and April? And that 86 percent of landslides are caused to some extent by human activity? Landslide season is upon us. Today the USGS rain gauge used to anticipate the likelihood of landslides in the area moved about the threshold, meaning some level of landslide activity is likely in the coming days. The City of Seattle urges residents to take preventive measures to protect themselves and their property from possible landslides.

Landslide experts agree there is not one single factor that contributes to landslides in the area, but in most cases there are steps that property owners can take to mitigate risk.

With 20,000 Seattle properties (mostly residential) in landslide-prone areas, the
City of Seattle and the Take Winter By Storm campaign encourage property owners to take preventive measures to protect themselves from landslides, and learn more about how to manage hillside property by attending a free landslide awareness meeting.

2012 City of Seattle Landslide Awareness Meeting – November 10.

The free landslide awareness meeting will give the public the opportunity to consult with public/private landslide experts and learn simple preventive measures that will help protect them from future landslides, such as the following:

• Clearing nearby storm drains of leaves and other debris
• Checking downspouts; making sure they are functioning/routed to a safe location
• Inspecting sloping areas for indications of slope movement and erosion
• Keeping fill and yard waste off slopes
• Shutting off the irrigation system and checking it out seasonally
• Leaving tree stumps in the ground on slopes
• Knowing when to seek professional help for hillside projects

2012 City of Seattle Landslide Awareness Meeting

The landslide awareness meeting will include a presentation that discusses the causes of landslides, proper drainage for sloping sites, and vegetation maintenance on slopes. The presentation will be followed by a question and answer session and time for one-on-one discussions with professionals in the field, including the City of Seattle, and volunteers from The American Society for Civil Engineers, The Association of Engineering Geologists, The International Society of Arboriculture, and Associated Building Contractors.

Nov. 10, 10:00 a.m. – 12:00 p.m.
Northgate Community Center
Multipurpose Room
10510 5th Ave. NE
(across from Northgate Mall)

Seattle Landslides

The landslide record that was documented in the Seattle Landslide Study of 2000 indicates that 86 percent of landslides that have occurred in the city have some human influence such as excavating and filling on steep slopes, broken pipes and uncontrolled storm water.

Since the devastating landslide season of 1996/1997, which involved over 300 reported landslides, the city has taken steps to prepare and respond to slides by constructing mitigation projects to reduce the potential for future slides. It has also been presenting these public landslide awareness meetings for owners of landslide-prone property.

If a landslide damages your property and you have an immediate concern for your safety, leave the premises and call 9-1-1. Seattle property owners with structures that may be affected by or endangered by a landslide should contact a geotechnical professional for structural evaluation.

Water Service Restored in Aftermath of University Bridge Main Break

FOR IMMEDIATE RELEASE: 5/2/2007

Water Service Restored in Aftermath of University Bridge Main Break

Bridge Remains Closed Until Further Notice; Update Expected Later This Evening

SEATTLE — Water was restored to areas of Seattle’s Eastlake and Capitol Hill neighborhoods at 5 p.m. today, following a morning break in a 24-inch water main which shut down the University Bridge and disrupted water service to some local business and residences.

The bridge remains closed until further notice, and commuters are advised to find alternate routes. An update on the bridge’s status is expected later this evening.

The cause of the water main break, first reported at 7:36 a.m. on Portage Bay Place which runs under the south end of the bridge, is still under investigation. The bridge was closed at 7:45 this morning as a precaution.

At around 11 a.m., Seattle Public Utilities (SPU) crews had completed the complex job of shutting off the water main, which involved closing a number of valves. Water pressure in the pipe had been slowly reduced to avoid damage to the system. Crews were finishing up the process of restoring limited local service.

Two unoccupied, parked cars, which fell into a large sinkhole caused by the break, have been removed.

Seattle Department of Transportation engineers were on the scene to determine whether there has been any structural damage to the bridge.

Some Metro buses are being rerouted. For more information call 206-553-3000, or go to https://transit.metrokc.gov.

Seattle Public Utilities (SPU) received several hundred customer phone calls who have lost water service or pressure due to the broken water main. Water pressure has been restored to neighborhoods outside the affected project area.

The City’s water is safe. If you have discolored water, as a general precaution we recommend that you wait until the water clears before drinking it.

• There is no reason to believe that contamination entered the water system.
• Discolored water results from internal pipe rust getting stirred up with changes in flow and pressure.
• If the water does not clear, let the water sit for an hour. Then run the water for a few minutes and flush the toilet a couple of times. If the water remains discolored, please contact SPU Customer Service at (206) 684-3000.

Only one leak in the cast iron water main has been reported in the last 15 years.

The section of pipe that broke is 90 years old. There are 147 miles of cast iron pipes in Seattle’s system. This pipe is a feeder line which is part of the backbone of the distribution grid for the City.

The last similar break was on Western Avenue in 1998, near Pike Place Market. A major contributing factor in that break was a footing for a pedestrian walkway that was directly over the pipe. Small but repeated loading caused a crack that ultimately leak to the break.

The cause of the current break remains under investigation. The existing pipe had a 12-foot longitudinal split.

The durability of cast iron pipe is influenced by how well it was installed, the surrounding soil, the presence of vibration and other loads over the top of the pipe. Based on these factors and the current leak rates, SPU assessed that the life expectancy of pipes in its system is 150 to 200 years.

In Seattle, pipes are monitored based on their leak history. Pipes that have frequent leaks are typically replaced.

SPU has benchmarked its system nationally and internationally. The results show that Seattle has one of the most robust water systems in the world. Our leak rate is one-third of the national average, and one-tenth of Australia’s.

In addition to providing a reliable water supply to more than 1.3 million customers in the Seattle metropolitan area, SPU provides essential sewer, drainage, solid waste and engineering services that safeguard public health, maintain the city’s infrastructure and protect, conserve and enhance the region’s environmental resources.
