The City of Kenmore participates in the countywide asphalt overlay program on an annual basis. The city collectively participates with other King County cities and unincorporated areas in one large hot mix asphalt contract to help reduce costs. The asphalt overlayprogram is part of a maintenance plan designed to prolong the life of city streets.
Streets are selected for resurfacing using a pavement management program that rates the conditions of city streets, which allows the city to prioritize streets for maintenance. Streets are then grouped together by location to minimize cost associated with mobilization of paving crews. This year’s overlay program is scheduled to start the week of September 3.
What to expect:
Phase 1: Prep work
Prior to paving, Kenmore Public Works crews will repair deteriorating sections of pavement, grade the shoulders to expose the edge of asphalt, trim any low overhanging trees or shrubs that will be in the way for the dump trucks, and perform any other work necessary to prepare the roadway surface for paving.
Phase 2: Grinding and paving
Up to seven days before the overlay paving begins, crews will grind the transition joints, side streets and curbs. Paving work requires numerous pieces of heavy equipment to haul, place and roll the asphalt. Due to the nature of paving and the amount of equipment needed, the work zone can be quite lengthy and will cause significant traffic delays during construction hours.
Phase 3: Traffic markings and other work
In the days following the paving, crews will be on site to perform work such as installing traffic markings, placing crushed rock along gravel shoulders and driveways and adjusting utility valves and manhole covers. Drivers can expect delays during these activities but these delays are generally much shorter than those experienced during the grinding and paving phase.
Activities will normally take place Monday through Friday, between the hours of 7 a.m. and 5 p.m. However, there may be instances when work activities will need to take place outside the normal periods. The project is expected to take approximately four weeks to complete. However, weather or unforeseen conditions may affect the overall schedule.
