System Overview

One of the greatest challenges a City faces is maintaining, preserving and restoring its paved streets. Even though transportation/street maintenance is one of the few areas where cities receive regional and state monies (TransNet, Proposition 42, Proposition 1B), needs continue to exceed available funding. Most public agencies face financial constraints and must make choices about how to spend their limited transportation/maintenance dollars.  Every few years, the City hires a consultant to update its Pavement Management System (PMS) in order to provide an objective assessment of pavement condition citywide.  The state requires a PMS in order for a jurisdiction to be eligible for state funding.  The PMS develops pavement preservation and rehabilitation strategies to maximize the use of public funds by applying the right treatment at the right time to extend the life of the pavement.

Pavement Condition Index (PCI)

Below are photographs depicting examples of 5 different PCI scores.

The PMS process begins with each of the street segments being rated with a Pavement Condition Index (PCI) between 0 and 100 (with 100 being “like new”). The scores translate into six general condition categories, ranging from "Failed" to "Excellent." Each score range is assumed to warrant a specific type of treatment. Treatments can be thought of in three general categories – seal, overlay, and reconstruct, with reconstruct being a complete rebuilding of the pavement roadway.  The computerized Pavement Management System then begins a complicated process of prioritizing Chula Vista's over 2,800 street segments to determine the most efficient and effective use of anticipated funds over multiple years.

PCI % of Streets Actions Required Cost per Square Foot
70.01 - 100 78% Requires maintenance treatment only (such as thin seals). $0.35 - $0.65
50.01 - 70 13.7% Requires rehabilitation (such as seals with digouts, overlays). $0.35 - $4.25
25.01 - 50 7.3% Requires major rehabilitation (such as rubberized or thick overlays). $4.00 - $5.00
0 - 25 0.5% Requires complete reconstruction (removal and new construction of pavement and base layer underneath). $8.50 - $15.00

The system considers a number of factors to determine priority, including street type and use, (i.e., number of lanes, total traffic volumes, and heavy truck volumes), street pavement condition rating, and the cost effectiveness of various treatment strategies. The end result is a multi-year list (usually a five-year list) of streets and strategies that maximizes citywide pavement life using available and anticipated funding, while preventing streets in good condition from becoming poor and, therefore, more costly to maintain.

The Pavement Management System has determined that about $19 million per year over the next ten years is required to maintain the current overall citywide condition rating.  However, available funds for pavement rehabilitation are extended estimated to average about $5.5 to $6.0 million per year over the next five years.  Due to the shortfall in gap between needed and actual funding, the City is focusing on preserving street pavements that require less costly maintenance and rehabilitation procedures, while looking for alternate funding to re-build and/or reconstruct streets that are beyond repair.

As a result, there will be more newer streets that will receive less costly preservative treatments such as less-costly seal coats than in previous years.  This strategy will extend the life of those streets by several years and delay or prevent, if possible, having to use more expensive pavement treatments in the future, including overlays.  Based on the limited funds available, this is the most cost-effective strategy to maintain the best pavement condition Citywide.
