Snow Removal

Shoreline crews have been working 12-hour shifts plowing primary routes as snow has continued to fall. As snow transitions to rain, they will finish clearing primary and secondary routes and begin to move into neighborhoods. Plowing heavy, wet snow takes time. We appreciate everyone's patience as crews continue to clear roads.

Please continue to stay off the roads, if you can, to give crews a chance to clear them.
For more information: Snow and Ice Control Plan.

Storm drains and localized flooding

As temperatures increase and we transition from snow to rain, street drains and culverts can plug as chunks of snow and slush move towards the drainage inlets. 

If this occurs there may be localized flooding as the water ponds or bypasses plugged drains. City maintenance crews will be clearing drainage inlets and culverts but may not be able to catch them all in advance of a problem. 

You can help prevent problems in your area - if you see snow plugging a drain or culvert consider clearing it and putting the snow uphill of the drain where it can melt without causing problems.

Locate storm drains near your house

A similar situation can arise on roofs with snow that may plug roof drains or scuppers as it melts. If possible, monitor your roof and maintain the roof drains. Some structures, such as out buildings and carports, are at a higher risk of collapse under wet snow, so please use caution.

Heavy snow on tree branches

Heavy, wet snow can increase the potential for downed limbs and power outages. DO NOT try to clear branches from lines or go near any downed power lines. Call Seattle City Light at 206-684-3000 or 206- 684-7400 to report downed lines or call 911 to address any situation where a downed line might cause a dangerous situation.

Sink hole on 3700 block NE 178th Street

Wednesday, November 28, 2012

On Friday, November 23rd due to high water flows in McAleer Creek, the roadway subsurface in the 3700 block of NE 178th Street washed away around a culvert pipe creating a sink hole. LFP City Engineer Neil Jensen is assessing the damage and is arranging for a repair.

In the meantime, Public Works crews have installed a steel traffic plate over the affected area. Asphalt cold patch was used to secure the plates in place and make for a smoother transition for traffic. Traffic signage has been installed to warn motorists of the bump in the road surface.

Avoid flooding problems by taking precautions

Tuesday, November 20, 2012


Drainage and flooding is a major concern for many Shoreline residents. The City manages drainage problems through maintenance and upgrades of the stormwater drainage system. Watershed maps with storm pipe and stream network are available here.

Examples of drainage problems include clogged storm drains and ditches and localized ponding of water in City streets.

Identifying a Drainage Problem

Drainage problems can cause significant damage to your home, property and the City of Shoreline storm drain system. It is important to identify and correct drainage problems when they occur. Before starting any drainage improvements on your property, fully identify all parts of your current drainage system. Create a detailed map of your property, showing all impervious surfaces and drainage features. Shoreline’s Public Works Department can provide information on the City’s storm drainage system in your area, which you could use to determine how your current system is connected to the City’s system and for the installation of additional components.

Shoreline residents in need of assistance contact the City at 206-801-2700.

Tips to Prevent Drainage Problems

To reduce the amount of impervious surface area on your property (and decrease the amount of stormwater runoff), consider alternatives when planning new patios, paths or driveways. Paving blocks, porous asphalt or other permeable materials can infiltrate water (see page 11 of the Managing Rainwater Guide). Green Home Remodel Guide Managing Rainwater

Tips to avoid future drainage problems:
  • Sweep your driveway instead of using a hose. This saves water and keeps dirt out of your drainage system.
  • Avoid the use of wood chip mulch around drain inlets or swales. The wood chips float and can be easily moved by runoff water.
  • Use caution when planting trees or shrubs. The roots may grow into underground drainage pipes disrupting your drainage system.
  • Install a removable connection between your downspouts and roof drains. Disconnecting downspouts during cleaning will help keep debris out of your drainage system.
  • Add screens on gutters to help keep debris out of your drainage system.
  • Help to keep catch basin inlets clear by keeping leaves off of the grates.

Drainage on your property

You as a property owner are responsible for the installation and maintenance of necessary drainage structures on your property. If your drainage problems seem too big for you to correct, there is professional help available.

There are many contractors and engineering firms that specialize in drainage problems. They can be found in the yellow pages under Drainage Contractors, and Engineers – Drainage.
The City of Shoreline requires homeowners to obtain building or grading permits before certain drainage projects begin. To find out more information about permit requirements, contact the City’s Planning and Community Development Department at 206-801-2500.

Broken water main causes flooding in five homes

Wednesday, January 12, 2011

Photo courtesy Shoreline Fire
Shoreline Firefighters responded to a broken, 12-inch underground water main this morning, just before noon. The break occurred at 28th Avenue NE and NE 160th Street, near Lake Forest Park. Shoreline Water District also responded, and shut off water service to several blocks while repairs are made. Firefighters canvassed the area, and found at least five homes with basement flooding, and many with pooling water in their yards and driveways. No was was injured, and no one was required to leave their home. Traffic to the area was re-routed for several hours, and it is unknown at this time when repairs will be complete.
--Shoreline Fire

According to Shoreline Water District Manager Stu Turner, the pipe was dug up and replaced by 3 pm today.  While repairs were being made, several hundred homes and businesses were without water.
All water service should have been restored.

Storm aftermath - not as bad as it could have been

Wednesday, December 15, 2010

by Diane Hettrick

I am sensing a tone of relief from our cities and county in the wake of this last storm. Having over three inches of rain in 48 hours, into ground already full of water, could have caused serious problems, but didn't.

King County Executive Dow Constantine pointed out that the damaged homes shown in the media were not those which had been permitted or built in the last ten years.

“Policies to limit construction on steep slopes and protections for flood hazard areas are doing a better job of making our homes and neighborhoods safer and more resistant to damage from severe weather.”

Shoreline has been working for several years to solve and prevent flooding. Cromwell Park, which was completed this summer, was designed to hold storm water and prevent it from flowing into Ronald Bog. In previous weather events, Ronald Bog overflowed its banks and routinely flooded a section of homes to the south of the Bog. One year it even covered a block of Meridian Avenue.

Ronald Bog overtopped its banks but did not flood Meridian.

This year, while the Bog filled to the brim, it apparently did not flood nearby homes. Incidentally, the City obtained old aerial survey photos of Shoreline and discovered that the homes by Ronald Bog with the flooding problems are built on an area which used to be part of the Bog.

Shoreline Public Works had 22 calls related to flooding.
"While this is not an insignificant number, it is significantly lower than what the City has experienced in the past during a major storm event. A number of areas in the City that historically had severe flooding issues did not have any problems with this storm."
Shoreline did a lot of work ahead of the storm which they feel minimized the damage.
"City crews prepared the week before with street sweeping, catch basin cleaning, and jetting of problem lines. City crews will continue to take preventative steps throughout the winter."

Lake Forest Park has a much more serious problem. The Towne Centre sits at the outflow of two watersheds - McAleer/Ballinger and Lyon Creek. McAleer Creek comes from the joining of streams flowing out of north Shoreline and Lake Ballinger. Lyon Creek comes from the watershed to the north, which includes Lynnwood. The two streams are within feet of each other at the Mall. The Sheridan Beach neighborhood is in the path of these streams as they head for Lake Washington.

Several years back, when flooding was rampant and hillsides were sliding, 40 homes in Sheridan Beach either were flooded, or worse, filled with sewage when the sewer lines filled with storm water and backed up into the houses.

That year, several homeowners told me, it happened so fast they barely had time to react. They went outside to look at the flooding and went back inside to a home full of sewage.

This year, knowing the potential problems, LFP was right on top of it.
"Staff joined the fire department to go house to house in the Sheridan Beach area, informing citizens about the flooding and to check on people. There was one sewer back up and the City responded with a pump to divert flows from one trunk line to another."

Solving the upstream problems is complex and will be very expensive. The Lake Ballinger Watershed Consortium, which has included representatives from five cities, two counties, state and county officials, has been meeting for several years, working on solutions for flooding and pollution problems in that watershed. There is no consortium for the Lyon Creek Watershed.

Lake Forest Park is applying for Federal grants for flood control for an estimated three million dollars.

In the meantime, here is the link for the LFP sandbag depot and emergency information.

A final word of warning from County Executive Constantine,
“As our population grows and the recession eases, pressure will build once again to allow new business, residential and infrastructure investments in the floodplain,” said the Executive. “We need to keep in mind that we've had 11 Presidentially-declared flood disasters since 1990, and we must continue to site development and infrastructure in a way that will be economically viable, environmentally sustainable, and safe."

LFP flooding - some updates

Good news - the diversion which was designed to route the storm stream away from the Northshore fire station in LFP Towne Centre is working and the fire department is dry. Readers may recall that in the significant weather event of a few years back, a stream appeared and ran right through the middle of the new fire station. Firefighters just opened up the doors on each side of the building, stacked sand bags on each side and let the water run through.  Thanks to Sen. Fairley for getting the money for that project.

I understand that traffic is getting through on Bothell Way, so either the flooding receded or it was short-lived.

Some houses on McAleer Creek had water up to the doorstep.

I was in Towne Centre on Friday and the portion of Lyon Creek in the mall was all the way to the top of its banks. I imagine it's a little higher now.

I don't plan to check in person, so if anyone has a view out their windows, tell us what's happening.
