With snow in the overcast for the next several days and a potential for 6 to 8 inches of accumulation we want to make sure everyone has the most up-to-date information for cold weather preparedness and snow routes.

The City of Sammamish receives a lot of questions about City procedures before, during, and after snow events. They have compiled many of them below with the answers from our Streets and Stormwater Division experts.  

How does the city prepare for snow and ice events and what happens when the snow hits?

  • City of Sammamish has a snow plowing priority system in place to clear our 400 lane miles of public roads and over 730 cul-de-sacs
  • Once a snow or ice event has been forecasted and the likelihood of snow is high, the crews apply a layer of anti-icer to all roads
  • After the snow starts to fall/accumulate, snowplows are operated 24 hours a day until the end of the event, or several days after depending on the severity of the event
  • The plowing time required depends on several variables such as the snowstorm intensity, duration, and the temperature before, during, and after

How do you decide which streets to prioritize?

  • For any snow event, our number one goal is to keep designated priority routes in good winter driving condition
  • Priority routes are lifelines, major thoroughfares, and arterial roadways and streets

The city does not plow private roads; we have 80.6 miles of private road.

Why doesn’t the city de-ice and plow all the streets – specifically secondary and residential streets?

  • The City has 400 lane miles to cover and limited resources, including snowplows (we have nine), storage capacity for de-icer and salt to treat surfaces, and maintenance personnel
  • Our priorities have to focus on ensuring accessibility for lifelines, main arterials and thoroughfares, main connector streets, and major hills and curves
  • During snow events our crews and snow removal equipment are out on the streets 24 hours a day
  • During previous snow events, we had three of our snowplows working to keep 228th clear full time
  • We do not plow or deice private roads or driveways

What do you do about medical emergencies?

  • If there is an emergency, call 9-1-1
  • The City always works with emergency service providers when emergency response is necessary

What kind of equipment does Sammamish have to deal with snow and ice?

  • Sammamish has twelve snowplows to cover 400 lane miles of roads, and over 730 cul-de-sacs
  • All plow trucks carry either a sander or a liquid deicer tank. Our inventory of sanders and deicers include a total of 12 sanders ranging from 3 to 8-yard capacities and 6 truck mounted deicing tanks ranging from 300 to 500-gallon capacities
  • The Maintenance and Operations Center has capacity for 250 yards of road salt and 35,000 gallons of deicer. Just prior to a snow event, we are already ordering more supplies (deicer & road salt) to replenish our stock. There is at least a three-day lead time for both products as well as a priority system with the State and Counties having first priority

 

What do you use for de-icing?

  • We use a liquid deicer called CCB, it’s made of calcium chloride (salt), molasses, water, and a corrosion inhibiter called boost, which is a proprietary ingredient

Why doesn’t the City use sand?

  • Under our NPDES Phase II Municipal Stormwater Permit, the city is required to start the removal of all sand used within the roadway within 24 hours after the road is clear of snow and ice
  • Due to this restriction, we only use sand in certain instances, locations or if our supply of road salt is interrupted due to delivery or supplier issues

Are there any tips for safe driving during snowstorms?

  • Slow down in winter weather; driving too fast for conditions causes most accidents
  • Take the extra time to clear your car of snow and ice before leaving for your destination
  • When driving at night, keep your headlight beams low – high beams can amplify the appearance of snow and lead to decreased visibility
  • Carry tire chains in your car and know how use them – here’s information on how to install tire chains; there are also many videos available on YouTube https://www.wikihow.com/Install-Snow-Chains-on-Tires
  • Always wear your seatbelt
  • Do not abandon your car in the middle of a road – it’s a hazard for other drivers and may block the path of emergency response vehicles and snow plows

Will the snowplows ever completely clear my residential street down to bare pavement?

  • It is not the goal of the City's Snow and Ice Policy to have all streets clear down to bare pavement

I saw the snow plow in my neighborhood but it did not plow my street/cul-de-sac?

  • Once the priority 1, 2, 3, and 4 roads are in good shape our crews will start working on the neighborhood streets
  • The first goal once neighborhood street plowing begins is to get the main road through a neighborhood passable (not clear) – from there the crews will work on the major hills
  • It is important to remember that our crews still have to maintain the priority roads. They may start your neighborhood and have to leave to do so

How long will it take to finish plowing all the streets?

  • This depends on the severity of the event, but our crews and equipment are out working 24 hours a day during snow events

How do I report that the snowplows missed my street?

  • Please do not use  My Sammamish Fix It/See Click Fix to report that your street has not been plowed
  • Please do not call Public Works to report that your street has not been plowed – if it is an emergency, call 911
  • Our crews and plows must work on priority routes first and then move on to working on the neighborhood hills and arterials
  • When snow continues to fall, plows will not be available to clear local residential and less-travelled roads as they must continue working to ensure major roads and transit routes are clear

What can I do about snowplows that block my driveway with snow?

  • This is an unfortunate side effect of plowing – snow must be plowed to the curb and, as a result, sometimes driveways get blocked
  • It is the property owner's responsibility to clear the snow from the bottom of the driveway –please, do not put the snow back in the street

What can residents do to help during snow and ice events?​

  • First, avoid driving if it’s at all possible
  • Park all vehicles in driveway/off the street
  • If you have room, share driveway space with your neighbor
  • If able, shovel snow away from hydrants and drain inlets
  • When shoveling or using a snow blower, do not deposit snow into the street

Why do the plows cover over the areas I just shoveled? Am I responsible for those areas? 

  • When snow plowing takes place, snow is not removed but rather pushed to the right side of the road
  • Snowplow drivers will make every effort to avoid plowing snow onto sidewalks or driveways; however, there may be times that this cannot be avoided and sidewalks or driveways may become blocked
  • It is the property owner's responsibility to clear the snow from the bottom of the driveway – please, do not put the snow back in the street

I saw a city snowplow driving around during the storm with its blade up. Why wasn’t it plowing? 

  • It is the goal of the city to plow streets systematically based on priorities
  • When snowplows are moving from one location to another, or returning to refuel or have more de-icing material loaded on the truck, they may travel with their plow blades up
  • Also, once the de-icer is applied, we do not plow so the product has time to melt the ice and snow

Who is responsible for shoveling around the group mailboxes and sidewalks?

  • If the group mailbox fronts to a neighborhood sidewalk, the adjacent property owner or Homeowner’s Association (HOA) is responsible for shoveling the sidewalk in front of the group mailboxes, in a similar fashion to sidewalk clearing requirements
