Subject:

Measure X Regional Pavement Management Program Report


RECOMMENDED ACTION:

RECEIVE results from the 2019 pavement management monitoring program from local jurisdictions in Monterey County as required by Measure X funding allocated to roadway repair.

SUMMARY:

Measure X outlines the requirements for the use of local road maintenance, pothole repair and safety funds. It includes a requirement for each jurisdiction to have a pavement management program (PMP). The pavement management program examines the overall condition of the street network and highlights options for improving the network’s pavement condition by conducting "what if" analyses. The main data point used in this analysis is called the pavement condition index (PCI). TAMC hired a consultant team in 2018 to develop a pavement management program for jurisdictions that needed this assistance. This report summarizes the results from the 2018 pavement monitoring program.

FINANCIAL IMPACT:
Measure X allocates 60% of the funds received to local road maintenance, pothole repairs and safety.  The funds are distributed to each local agency in compliance with the approved ordinance.
DISCUSSION:

The approved ordinance for the Transportation Safety & Investment Plan (Measure X) defines the requirements for the use of local road maintenance, pothole repair and safety funds. It includes a requirement for each jurisdiction to have a pavement management program. "Each city and the County of Monterey shall develop, or participate in the development of by TAMC, a pavement management program. They shall submit regular reports on the conditions of their streets, to ensure timely repairs and keep the public informed.  Development of the pavement management program by TAMC is eligible to be funded out of this program prior to distribution of funds to the cities and the County." The Measure X funding agreement includes requirements that jurisdictions must complete the following pavement management program tasks:

  • Review and update the pavement information for all roads every two years.
  • Re-inspect pavement conditions of arterials and collector streets every three years.
  • Re-Inspect pavement conditions of residential streets and local/rural roads every six years, unless otherwise approved by the Transportation Agency.

 

In order to receive Measure X funds, the cities and the County shall utilize a pavement management program and submit regular reports on the conditions of their streets, to ensure timely repairs and keep the public informed. The pavement management program should utilize an approved software-based tool for analyzing pavement conditions and report findings on rehabilitation/maintenance strategies based on funding levels. The pavement management program used by the jurisdiction must contain, at a minimum, the following features:

  • Store the inventory all roadways within a jurisdiction (in a compatible database with other jurisdictions).
  • Assess the condition of the roadways (based on seven distresses and three severity levels).
  • Provide the current PCI for the roadways (as per ASTM D6433). It is important to note that the StreetSaver and Micropaver software programs meet this requirement.
  • Identify all pavement sections needing maintenance, rehabilitation, or replacement.
  • Calculate budget needs for maintenance, rehabilitation or replacement of deficient pavement sections (for the current year and the next three years at various overall condition levels).
  • Develop maintenance strategies for the most cost effective level of maintenance or repair appropriate at the time of the inspection.
  • Generate pavement management program reports (in various formats).

 

Pavement condition is primarily affected by the climate, traffic loads and volumes, construction materials and age. The pavement management program examines the overall condition of the street network and highlights options for improving the network’s pavement condition by conducting "what if" analyses. The main data point used in this analysis is called the pavement condition index (PCI). A PCI is calculated for each roadway segment surveyed, and then these survey results are used to calculate a weighted average PCI score for the entire roadway network for that jurisdiction. The PCI score is categorized by the pavement condition per the following table:

 

 

In February 23, 2018 the Transportation Agency hired the consulting firm NCE to assist local jurisdictions prepare a pavement management program. Attached is the NCE report that records the results of the 2018 pavement management program for the local jurisdictions that participated in this effort. The following table summarizes the pavement management data for the jurisdictions that participated in the NCE project:

 

  

 

The countywide local street/road network evaluated by NCE represents 1,345 centerline miles with an estimated replacement cost approaching $1.4 billion. This can be viewed as the value of the pavement network and is the amount needed to fund reconstruction of the entire pavement network. This value does not include related infrastructure assets such as sidewalks, signals, markings, or signs. The weighted average pavement condition of roads in Monterey County evaluated by NCE is calculated to be 52 which is considered "fair" condition. This compared to the statewide average PCI 65 which is also considered "fair" condition. The remaining service life for the roads evaluated by NCE was reported to be 10 years, and this is an estimate to when the average pavement is expected to reach failed conditions (PCI<25).

 

Some agencies in Monterey County decided to develop their own pavement management program and reported the following data to the Transportation Agency to meet their Measure X requirements:

 

 

Local agencies are also asked to submit pavement conditions as part of a statewide effort that is reported annually as the California Statewide Local Streets and Roads Needs Assessment that was prepared by NCE. The following data illustrates the different pavement conditions reported to the Transportation Agency as well as the data received by NCE to prepare the statewide report. The table also includes the report prepared by the Regional Transportation Planning Agency. There are some discrepancies in the data that make it difficult to conduct a formal trend analysis.

 

 

 

To assist local jurisdictions meet their ongoing pavement management program requirements, the Transportation Agency staff is in the process of procuring a consultant to provide services available for those agencies selecting to participate. Other jurisdictions must submit their own pavement management program in order to meet Measure X requirements.
