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, StreetSaver pavement management system recommendations, and available funding to implement projects throughout the unincorporated County.  DPW’s pavement management program allows staff 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 the pavement on 1,944.25 miles of the County’s publicly maintained roads.  


On April 28, 2017 the Governor approved the new transportation funding plan entitled, “Road Repair and Accountability Act of 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.  At the start of our Program, our PCI was 60. 


A significant component of DPW’s Annual Roadway Resurfacing Program is community outreach.  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 the annual roadway resurfacing program. The input received from the communities is used by staff to assist in the development of 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 are anticipated projects DPW plans to accomplish in the next few years.

Unfortunately, COVID-19 is negatively impacting many County functions including road maintenance and resurfacing projects, and County’s allocated State gas tax revenues have decreased by up to 30%.  During these challenging times, we remain committed to providing the public with essential services.  To be proactive and to ensure continued essential operations match the funding we receive, DPW has reduced resurfacing funding over the next few years from $56M to $40M.  As the full impact of this public health emergency becomes clear and once State gas tax revenues increase, DPW intends to restore its Resurfacing Program funding to pre-COVID levels.  

Currently, funding for 2020-21 (Year Four) resurfacing projects has been reduced as a result of COVID-19.  However, road resurfacing deferred from Year Four will be added to Year Five resurfacing projects.    


DPW's goal is to identify the most effective means to properly maintain the County roads and keep them safe and passable for residents and roadway users.  DPW’s engineers continuously survey roads for the 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 the field work is complete, more specifics will be provided on this website to identify the type of surface treatments DPW will use for each individual road segment.

DPW’s annual resurfacing program is routinely updated as the plan evolves.  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 the project lists that include specific street names with limits of proposed work with utility companies and adjacent cities to ensure proactive coordination of construction projects between the agencies. This effort will reduce premature damage to the public roads through avoidable utility pavement cuts and will improve the service life of the pavement.


As a result of the State’s SB-1 funding and Board direction, DPW is pursuing a plan to achieve a PCI of 70.  DPW initiated an action plan to achieve a steady increase in PCI over seven fiscal years by completing multiple resurfacing projects.  DPW’s current PCI is 63. 

For 2017-18 (Year One), DPW awarded five separate resurfacing projects that started construction in late 2018.  The 2017-18 project includes approximately 154 miles of resurfacing work with additional projects that included replacement of culverts, and other accessibility improvements.  The project list that includes the specific roads to be treated is updated and available on this webpage.  The 2017-18 projects are complete.

The 2018-19 resurfacing projects (Year Two) began construction in summer 2019.  These projects are estimated to include approximately 131 miles of road resurfacing, replacement of culverts, and other accessibility improvements. The 2018-19 projects are anticipated to be complete in summer/fall 2020.

The 2019-20 resurfacing projects (Year Three) received Board approval in late 2019 to bid and award the project.  All resurfacing projects are currently being prepared for competitive bid.  DPW has awarded some of the individual projects and anticipates awarding two more projects in the near term.  The projects are estimated to include approximately 135 miles of road resurfacing, replacement of culverts, and other accessibility improvements. The 2019-20 projects are anticipated to be complete by Spring 2021

The 2020-21 resurfacing projects (Year Four) are in the planning process.  DPW plans to go to the Board in December 2020 to receive approval to bid and award the projects.  The projects are estimated to include approximately 98 miles of road resurfacing, replacement of culverts, and other accessibility improvements.   

The anticipated total road resurfacing program for the first four years of DPW’s resurfacing program will result in the completion of approximately 518 miles of resurfaced roads, or about 27% of the total number of DPW’s publicly maintained roads.  DPW will continue to work on future year projects for the County’s road resurfacing program and will share updates on this website, when available.
