2015 ARBOR HEIGHTS MICROSURFACING PROJECTLast updated: May 7, 2015
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.
Please note that SDOT’s microsurfacing is for non-arterial streets that used to be chip-sealed; it does not include streets that:
How it will work
First, the roadway will be cleared of landscaping less than 14 feet high, including shrubs and bushes along the side of the street and tree limbs that are hanging 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 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:
This schedule will be updated with more details after we select a contractor.
Work in front of any one property is expected to last one day. Residents will receive letters with specific work schedules prior to construction. Microsurfacing will be scheduled (and accommodations made) to avoid conflicts with garbage collection and recycling pick-up as much as possible. Emergency vehicles will be allowed through the work area at all times without any delay.
