Many local neighborhood streets are part of the 2015 surface treatment work. The map above shows residential neighborhoods directly affected by paving work this summer - highlighted in orange.
The preventive treatment projects alternate each year between the east and west sides of Vancouver. The focus for 2015 is west of Interstate 205 and includes numerous neighborhood streets. The following associations will see preventive treatment work in or near their neighborhoods this year: Columbia Way, Dubois Park, Evergreen Highlands, Father Blanchet, Fourth Plain Village, Fruit Valley, Hudson's Bay, Lincoln, Northcrest, Northwest, Vancouver Mall and West Minnehaha.

Preventive surface treatment work planned for residential streets within the Northwest, Lincoln and Carter Park neighborhoods has been postponed. The City of Vancouver is still having Operations Crews prep streets for future work which includes sealing cracks, patching potholes and trimming trees and vegetation in the rights of way. The City hopes to schedule these neighborhood streets for future surface work within the next year or two.
The City of Vancouver is currently preparing work for its annual summer paving projects. From May until the end of July, crews will start the first phase of this work by installing new or reconstructing several pedestrian ramps to bring those corners up to current Americans with Disabilities Act (ADA) required standards. This construction will take place along streets slated for various preservation pavement treatments or overlay paving this summer.
The City of Vancouver has contracted with Integrity Excavating. Work hours are from 7a.m. to 5 p.m. Drivers, bicyclists and pedestrians should be alert to potential delays, traffic control devices, lane shifts, rough grades at corners, and other construction-related activities.
Adjacent properties typically receive a door hanger notice about a week in advance and then again 24 hours in advance of the work. The 24-hour notice includes a list of streets in your area that are also receiving treatment. This can help as you plan where you can park and drive when your street is being resurfaced. Please note that schedules and locations shown here may be adjusted when needed due to weather and construction conditions.
There are a variety of preventive surface treatments used to extend the life of streets at a much lower cost than a standard asphalt overlay. These surface treatments include microsurfacing, slurry seal, chip seal and cape seal. The type of treatment depends upon several factors, such as current surface condition, carrying capacity and travel use.
These projects alternate each year between the east and west sides of Vancouver. The 2014 focus was mainly east of Interstate 205, and the 2015 focus will be west of I-205.
The City of Vancouver has more than 1,800 lanes miles of streets. Each year, the City of Vancouver evaluates about half of those paved city streets and identifies areas where surface treatments could go the farthest in extending the life of the street and providing residents with better driving conditions. All paving applications are highly weather dependent. In case of rain, surface treatment work must be rescheduled.
As a precursor to the surface treatment work, crews installed new intersection curb ramps or retrofitted existing curb ramps at various intersection locations to meet compliance requirements of the Americans with Disabilities Act.
In most cases, residences and businesses fronting impacted streets receive door hanger notices in advance of paving. Within construction zones, drivers are asked to be prepared for delays, watch for traffic changes, proceed slowly, and be alert to construction workers, bicyclists, pedestrians and other motorists. Regardless of the type, all paving applications are highly weather dependent.
Construction hours are typically from 7 a.m. to 5 p.m., Monday through Saturday, though work may continue as late as 8 p.m. if needed. All paving applications are highly weather dependent.In case of rain, paving must be postponed and rescheduled.
Microsurfacing begins as a coarse liquid application of dense-grade aggregate, asphalt emulsion, water and mineral fillers. The quick-setting emulsion allows traffic to begin using the new surface in a short time, as little as an hour depending upon conditions. As the product cures, the surface becomes smoother. The finished sealant forms a thin shell over the street's existing asphalt surface, extending the life of the underlying pavement. Micro-surfacing applications are generally applied on arterial and higher volume streets, and the quick-setting emulsion allows traffic to begin using the new surface in a short time, as little as an hour depending upon conditions. Microsurfacing provides more durability than a slurry seal.
The benefits of microsurfacing include:
- Reduced user delays
- Corrections to minor defects and ruts
- Surface improvements
- Greater durability than slurry seal for high traffic areas
- Increased skid resistance
- Cost-effective, long-lasting pavement preservation
Slurry Seal is a mixture of fine rock, asphalt, and water placed on the pavement about ¼-inch thick to protect the surface from sun and rain. Slurry seal applications are generally applied on lower volume local and residential streets.
Chip Seal is a layer of sprayed emulsified asphalt and then a layer of new rock. A chip seal treatment typically extends the life of a road by seven to 10 years and provides a new sealed surface at a fraction of the cost of a standard asphalt overlay.
Cape Seal is a surface treatment that begins with a chip seal and then combines a final slurry seal, or even a microsurface, application. This treatment can greatly extend the life of the roadway.
