The Department of Public Works (DPW) solicits community input to improve services and maintain County infrastructure, and these efforts include identifying immediate and long-range road resurfacing needs. Development of DPW’s annual roadway resurfacing and construction program includes public input, operational needs, our computerized pavement management system recommendations, and available funding to implement projects throughout the unincorporated County. Our pavement management program allows us to focus maintenance resources on the best preventative maintenance measures and helps us to choose the most appropriate and cost-effective surface treatment, or resurfacing, ”to extend the service life of our pavement on 1,942.98 miles of County maintained roads.  


On April 28, 2017 the Governor approved the new transportation funding plan entitled, “Road and Repair Accountability Act 2017” also known as the Senate Bill (SB-1), which increased funding to local agencies for road maintenance projects.  As a result, DPW will be receiving approximately $538 Million in new funding over the next ten years for road maintenance purposes.  The State’s funding increases will be phased in over time.  This funding provides new opportunities to address DPW’s significant road resurfacing needs.  On May 2, 2017, the County Board of Supervisors (Board) directed staff to use the new funding to pursue additional resurfacing projects and achieve a Pavement Condition Index (PCI), a commonly used pavement rating system, of 70 out of 100 within five years.  DPW’s current PCI is 60. 


To better understand community priorities, DPW solicited input from community planning and sponsor groups to assist in identifying road resurfacing needs specific to each community.  DPW’s annual roadway resurfacing program included input from all 26 community/sponsor groups to develop our annual roadway resurfacing program. The input received from the communities will be routinely updated and used by DPW to develop subsequent years of the program.    


DPW must respond to unforeseen occurrences such as natural disasters, public safety emergencies, and other changes that could affect future project funding availability. Unexpected changes in DPW’s annual program may be necessary to accommodate changing needs throughout the County, but the resurfacing program presented here is our estimate of the projects DPW plans to accomplish. 


DPW's goal is to identify the most effective means to properly maintain our County roads and keep them safe and passable for our residents and visitors. Maintenance engineers continuously survey roads in our annual program to determine the most cost effective and appropriate surface treatments to apply. These surface treatments can range from a simple slurry seal to a more significant removal and replacement of the entire asphalt surface. Once our field work is complete, more specifics will be provided here on this website to identify the type of surface treatments DPW will use for each individual road segment.

DPW’s annual resurfacing program will be routinely updated as the plan further evolves. Currently, DPW has prepared project lists of road segments for future year(s) and they are included on this site. Typically, construction for each year of road maintenance projects occurs in the warmer summer months. 

DPW is sharing these project lists with utility companies and adjacent cities to ensure proactive coordination of construction projects between our agencies. This effort will reduce premature damage to our roads through avoidable utility pavement cuts and will improve the service life of the pavement.


Current Status

DPW’s first year (2015-16) of its revised resurfacing program was completed in June 2017 and is updated in the interactive GIS map and list of roads.  These resurfacing projects included over 53 miles of asphalt concrete overlays and surface seals.  These projects also included replacement of culverts and concrete drainage and accessibility improvements.  Resurfacing projects for the second year of our program (2016-17) were completed in January 2018 and included over 50 miles of asphalt concrete overlays and surface seals with additional projects to replace culverts and concrete drainage facilities and other accessibility improvements.   As a result of the State’s SB1 funding and Board direction, DPW updated our next phase of projects for 2017-18 and the upcoming 2018-19.    For 2017-18, DPW’s program is currently in the process of obtaining bids with construction beginning in summer 2018.  The 2017-18 resurfacing projects includes over 195 miles of asphalt concrete overlays and surface seals with additional projects for replacement of culverts and concrete drainage facilities, and other accessibility improvements.  For 2018-19, DPW’s resurfacing program is tentatively scheduled to go out to bid in early 2019 with construction beginning in summer 2019. These projects are estimated to include over 184 miles of road resurfacing, replacement of culverts and concrete drainage facilities, and other accessibility improvements.  The total resurfacing for the first three years of our revised program resulted in completion of approximately 320 miles of resurfaced roads.  With the new SB1 funding over the next two years, we are planning to complete 379 miles of resurfacing, or about 20% of the total number of our maintained roads.  DPW will continue to work on future years of the road resurfacing program and will share updates on this site when available.  View the interactive GIS maps to see lists of projects and roads for completed, current, and future projects.  Please follow this website to obtain the most current information and updates.

Resurfacing Completed and Planned 14/15 to 18/19
