2018 Paving Program

Project Description

Email list buttonAs the City of Lynnwood continues to grow, the wear and tear on our roads also increases. Our roads are the City’s single largest asset. Chip sealing (or Bituminous Surface Treatment) is a key part of the City’s preservation program to maximize the life of our roads. It is used in cities and counties across the country as a cost-effective method of pavement preservation. In fact, this process has successfully been done in the past on various roads through-out the City (i.e. 46th Ave W, 212th St. SW, etc.). New technology and better mix designs have improved chip sealing products, minimizing its impacts and maximizing its effectiveness. The treatment extends the life of each road by seven to ten years and provides a new sealed surface, at a fraction of the cost of an asphalt overlay.

Lynnwood thank you for your support of our streets. We are working hard to use your tax dollars in the most efficient and effective way. We realize chip seal construction process might create some inconvenience for residents, pedestrians, motorists and businesses.  When the work is complete, City roads will be safer and better-maintained. The City thanks you for your patience and cooperation during this work.

Chip Seal Information and What you need to know:

Chip Seal Fact:

  • Traditional chip seals often have a rough surface and a tendency to lose chips over time. This project will use smaller diameter chips and additional liquid asphalt on the top layer of the chip seal treatment to help prevent these issues and leave the new surface black and visually similar to regular asphalt.
  • Unlike asphalt streets, chip sealed streets can be driven on almost immediately after the surface is applied. However lower speed limits of 20 mph or less should be maintained to allow the aggregate to set and reduce the chance of loose aggregate damage to vehicles. 
  • Normal speed limits of operation are typically possible after the second sweeping (approximately one week) of excess aggregate.
  • Every phase of chip seal and fog seal require dry weather, and therefore work is dependent on weather.

Advantages to Chip Sealing:

  • Small cracks and distresses lead to bigger problems. A new seal prevents water saturation and extends road life.
  • Vehicles can drive on roads shortly after chip sealing.
  • Chip seals are a proactive and cost- efficient preservation process used nationwide.
  • Roadway life can be extended several years at a very low cost

Construction process:

What you need to know:

  • As construction dates get closer, the City (or its contractor) will coordinate with your neighborhood on more specific dates for your neighborhood’s chip seal application.
  • This surface treatment will require short duration lane closures or road closures, depending on the location. Drivers should expect some delays, but roads can be driven on shortly after application. Flaggers will guide drivers during construction.
  • There will be no parking on streets during chip and fog sealing and these will be temporarily designated as a “No Parking” zone. 
  • After a fog seal is sprayed, the roadway will need time to cure, with the time dependent on temperature, humidity and other weather conditions. Please keep vehicles, pets, children and adults off the treated roadway as it cures since material can be tracked into your home or vehicle.
  • Please refrain from washing your vehicle or watering your lawn and other vegetation immediately before, during and after applications. 
  • Remove basketball hoops, recreational vehicles and other items from the street and sidewalk.
  • For the first week, the treated surface can be damaged by vehicles making sharp turns, so please be sure your vehicle is moving before turning the steering wheel.
