About the program
Emergency roadway repairs and potholes could be minimized if sufficient funding were available for roadway paving. However, funding is not sufficient, and therefore to most effectively plan and coordinate roadway pavement rehabilitation, the city uses a pavement management program (PMP). The PMP provides an accurate inventory of pavement conditions and prioritizes cost-effective roadway repairs based on available funding such that the City maximizes the return on investment and provides the best overall pavement infrastructure.
The City of Santa Ana Public Works Agency maintains over 400 centerline miles of roadway. Some of our arterial (primary) roadways contain three and short sections of four lanes in one direction, while other streets such as our typical residential streets have one lane in each direction. Therefore, another measure of how much roadway we are responsible for is 1,130 lane miles comprising about 91 million square feet of pavement. This means, one would need to drive 1,130 miles in order to drive every lane in the City. The standard used by cities nationwide, Pavement Condition Index (PCI) is a numerical index based on field verified conditions and helps establish cost effective roadway repairs based on available funding. PCI is between 0 and 100 (0 meaning very poor street pavement condition and 100 meaning excellent street pavement condition) and it indicates the condition of street pavement.
The following maps are a graphical representation of the PMP, and the maps show street PCI in Santa Ana. The data used to generate these maps is collected every two years. The most current maps were created using 2017 field data and provide a snapshot of the pavement conditions. Since the maps were created in 2018, they are referred to as Streets PCI – 2018.
Note: a lower PCI does not necessarily mean that a street will be paved before one with a higher PCI. Other factors such as restricted grant funds, traffic volumes, and proximity to certain uses such as schools, play a key role in the decision process for when streets will be rehabilitated.
Reports and Map
Below is a list of maps that show the pavement condition index for every street in the City of Santa Ana:
- Current PCI (86-100) – excellent condition
- Current PCI (75-85) – good condition
- Current PCI (60-74) – fair condition
- Current PCI (41-59) – poor condition
- Current PCI (0-40) – Very Poor Condition
- Current PCI (0-100) – Combined
A fully-integrated PMP has had a positive effect on improving the City’s entire pavement network by developing efficient M&R strategies and analyzing the effect of various funding alternatives on the pavement conditions. The strategies include forecasting optimal time for Maintenance and Repair needs, providing cost-effective alternatives for halting the deterioration of existing pavement, improving the overall condition of the entire pavement network, and reducing the backlog of M&R work over the next seven years.
To carry forward one of the City’s main objectives in providing a safe, reliable, efficient, and comfortable driving environment, this PMP report analyzes various M&R strategies, the effect of the City’s existing Capital Improvement Program (CIP) funding on the street pavement system, and projected funding to both maintain and improve existing PCI. This citywide Alley report and the PMP report, which is updated biennially, are shown in the links below.
