Streets Maintenance Plan

Due: December 2025

Principle: Maintains existing roads and transportation network in tandem with snow and ice control services to ensure swift and safe transportation modes for the community.

Description

The new Streets Master Plan will be used to guide the Street Infrastructure Maintenance Program by forecasting and prioritizing the streets to be serviced and the treatment type or action to be performed. 

By understanding which streets are to receive some type of service the Streets Division can plan, organize, and prioritize what areas are to receive concrete replacement ahead of asphalt work to be performed. Understanding the yearly work type and scope provides the needed information to plan and budget accordingly.

Significance

The strategic result of completing and then implementing a master plan is paramount to the success of the program. A master plan allows the team to vet the proposed street work against other work systems and utility projects to avoid conflict and or damage to newly placed  asphalt or concrete. This strategy builds community trust, ensures everyone is on the same page when conducting street maintenance, maximizes resource utilization and helps improve product delivery.  

Analysis

The Street's Division pavement team will use a variety of data sources to develop the streets maintenance program.  This data is then entered into a software program called "PAVER" which helps the team understand current pavement condition, and will assist in predicting the correct course of action to maintain, conduct surface treatments, or rebuild the street.  These data sources include:

  • The PCI Index
  • Core samples to understand current pavement depth and sub-grade condition
  • Visual field inspection by the pavement team

The current database is out of date and incomplete.  To correct this issue, the pavement manager received formal training for PAVER and is in the process of correcting the database issues.  To assist with this work, the next action is to procure the assistance of a consultant whose expertise is in PAVER database design. The consultant will ensure our data is clean, that the data is entered correctly, and that all current and historical information is correct to permit the software to aid in the development of the master plan.

Pavement Condition Score

Description

In 2018, the City again contracted Atkins North America, Colorado to update the pavement management system (PMS) for the City’s (467 centerline mile/1525 lane mile) roadway network. The intent of the PMS is to provide the City with easily accessible inventory and management information for managing their pavement. The PMS also provides a framework for long term financial planning while easily assessing the implications of alternative funding levels. Finally, the PMS facilitates planning and implementation of a specific maintenance and rehabilitation program while monitoring its effectiveness.

Significance

Arvada’s transportation infrastructure is the City’s largest and most valuable asset. Citizens and businesses rely on traveling on safe and satisfactory streets. Arvada, like most communities in the United States has deferred street maintenance. As our population continues to grow, it is important for our community to understand the resources required to maintain this asset.


In order to update the PMS the Atkins team performed the following tasks as outlined in the statement of work:


  • City wide pavement condition assessment with the Cartegraph Automated Pavement Data Collection vehicle
  • Data Entry and Update existing pavement
  • Run pavement management scenarios
  • Summary report/project documentation
  • Verification of section widths (for new roadway sections)


Analysis

Historically we have used Micro Paver software to manage our data base for pavement management. Every three years the City would contract with a consulting firm to perform an inspection of our entire street network. The last analysis was conducted in 2018. Currently the Streets Division is pursuing the procurement of a replacement pavement management software which would include a new inspection of surface distresses and roughness, ride ability, deflectometry,  ground penetrating radar, and core analysis. Best case scenario appears that this integration may take us to the end of 2020 to complete. We are planning on contracting yearly inspections to include 1/3 of the city each year to provide ongoing current data versus waiting every three years.

Street Maintenance Funds

Description

The City allocates funds for street maintenance on a biennial basis. Over the past decade the cost of repairs has significantly outpaced the amount of money the City is able to dedicate to street maintenance projects. 


In November 2016, the City placed a measure on the ballot to increase City sales and use tax by 1/2 cent (5 cents on a ten dollar purchase) to fund only street maintenance and improvements. The ballot measure did not pass. The City remains committed to protecting this asset and is working diligently to increase street maintenance and improvement funding through budget reductions and dedication of one time funds.

Significance

According to the Pavement Condition Index (PCI) report In 2016, funding street maintenance at the current annual budget reduces the City's overall street rating annually an average of 1.8 points on the PCI Index. By 2019, Arvada streets would fall into the poor category. Congestion is also a significant issue in Arvada. Roads in poor condition and congestion impact quality of life and safety.

Analysis

Data Source

Budget data resides within the City's financial database while the funding required to stabilize or enhance Arvada streets is from the 2015 Pavement Condition Assessment update.
