Promises Made - Promises Kept
On April 28, 2015, Tumwater voters approved an increase in the sales tax rate from 8.7 percent to 8.9 percent for a period of ten years to fund street and sidewalk improvements. The new sales tax rate was implemented on October 1, 2015. Thank you, voters, for your commitment to maintain our community’s transportation system! The additional funding will only be used for these purposes.
Transportation infrastructure is one of the City’s most valuable investments.
The greatest need for the first year of this program is preparation for future surfacing applications. Thus, three main surface treatments will be used in the first year (2016) of the maintenance program. Arterial, collector, and neighborhood streets will be addressed in the 2016. Find out which neighborhoods will be the focus of street maintenance repairs in the Summer of 2016 on the Street Maintenance Map.
|Crack seal is the filling of moderately-sized cracks with hot liquid rubberized asphalt. It is the lowest cost of all treatments and is used to extend pavement life at the earliest possible time. It seals out moisture and chemicals and can be applied to any street, new or old.|
|Chip seal (or seal coating) is the application of a special protective wearing surface to an existing pavement. In this method, gravel chips and liquid asphalt are spread on the existing pavement and rolled in place to seal the road surface. This is a low-cost preventative maintenance method that extends pavement life, seals, and re-establishes surface traction and can extend the life of the road surface by 3-8 years.|
|Dig out (also called full depth repair) removes sections of failed roadway to the full depth of the pavement section, repairs the underlying structure by removing unsuitable material and replacing with crushed rock, then resurfaces the repaired area with hot mix asphalt. This prepares the damaged area for a future top surface application.|
