2015 ARBOR HEIGHTS MICROSURFACING PROJECT
Last updated: September 1, 2015
Update: Due to the rain over the weekend and the high probability of rain throughout this week, this work has been delayed. The microsurfacing treatment is not effective when applied in wet conditions. Work will be rescheduled within the next 2 weeks. Affected residents and businesses will be re-notified 2-3 days prior to construction as described below.
During construction, residents, business operators, employees and travelers in the Arbor Heights neighborhood will encounter detours as crews make their way through the area performing microsurfacing of city streets. Roads will be closed for up to 8 hours at a time.
What to expect during construction
2-3 days before the work begins, crews will place "no parking" signs on streets and distribute confirmation notices with dates and instructions. Cars must be relocated off the road and planting strip area prior to the start of work.
On the day of microsurfacing, please remove all personal items from the road and park cars on a nearby block not being microsurfaced. Noise, tar-like odors and large equipment associated with microsurfacing can be expected. To ensure best results, the street will be closed to vehicles for up to 8 hours. We encourage everyone to avoid the road surface during this time. When wet, the microsurfacing emulsion is sticky and difficult to remove from clothing and pet fur.
If your regular garbage collection or recycling pick-up is scheduled on the same day as this work, please have your bins to the curb before 6 AM to ensure collection.

As part of its Microsurfacing Program, the Seattle Department of Transportation (SDOT) is performing maintenance in the Arbor Heights neighborhood of southwest West Seattle. Microsurfacing is a cost-effective method to maintain roads by coating them with a protective sealant, extending their life by approximately 7-10 years. Unlike chip-sealing, this application process resurfaces the road without using or dispersing relatively large pieces of gravel.
The map below shows the streets that SDOT plans to microsurface in Arbor Heights in the summer of 2015.
Please note that SDOT’s microsurfacing is for non-arterial streets that used to be chip-sealed; it does not include streets that:
- Are privately owned
- Are concrete
- Were chip-sealed at one time, but have since been fully resurfaced in asphalt
- Have pavement that has degraded beyond the point where preventative maintenance can be effective
- Were microsurfaced in the 2014 Arbor Heights Project
How it works
First, in June and July 2015, the roadway was cleared of landscaping less than 14 feet high, including shrubs and bushes along the side of the street and tree limbs that hang over the roadway. Then, just prior to beginning the microsurfacing, the streets will be swept to remove loose dirt and debris.

On the day of microsurfacing, all personal items, including vehicles, will need to be removed from the roadway. Residents will need to park their cars on a nearby block not being microsurfaced.
During the microsurfacing process, large equipment will apply a thin layer of seal coat onto the pavement. The street will be closed to vehicular traffic for up to 8 hours to allow the seal coat to set. Residents, pedestrians and even pets should be kept off the emulsion until it has dried. Before it has dried, the microsurfacing emulsion will be sticky and difficult to remove from clothing or pet fur.
Microsurfacing must take place during dry weather to work effectively. In the event of rain, the work will be rescheduled.
The goals of the project are to maintain the roads using cost-effective methods and provide a safe driving environment. Benefits of the project include:
- Protecting the road surface
- Preventing the need for larger, more expensive road repairs in the future
- Creating a driving surface with improved skid resistance

Microsurfacing in Arbor Heights neighborhoods
Work in front of any one property is expected to last up to 1 day. If your regular garbage collection or recycling pick-up is scheduled on the same day as this work, please have your bins to the curb before 6 AM to ensure collection. Emergency vehicles will be allowed through the work area at all times without any delay.
