Project description

As part of its Microsurfacing Program, the Seattle Department of Transportation (SDOT) is performing maintenance in the Arbor Heights neighborhood of southwest West Seattle.  In the summer of 2015, crews will apply a protective seal coat on many neighborhood streets. This protective sealing, referred to as “microsurfacing,” is a cost-effective method to renew the road surface. Microsurfacing creates a protective layer that preserves the underlying structure and prevents the need for more expensive repairs in the future.

Below is a draft map of the blocks which SDOT plans to microsurface in 2015.
Please note that SDOT’s microsurfacing program does not include blocks where:

    1. The street is an arterial.
      • Microsurfacing is a program to maintain non-arterial streets in Seattle.
    2. The pavement is asphalt or concrete.
      • The purpose of SDOT’s microsurfacing program is to extend the life of “chip seal” streets.  Under similar conditions, asphalt and concrete streets last longer than “chip seal” streets before preventive maintenance is needed.
    3. The pavement has degraded beyond the point where the microsurfacing preventive maintenance treatment would be effective.
    4. The block was microsurfaced in the 2014 Arbor Heights Project.

This page will be updated later in 2015 with more details.  In the meantime, the 2014 Arbor Heights project page can provide examples of elements that may be included in future microsurfacing projects.
