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

This strategic result is paramount to the success of the street program. A master plan allows the team to vet the proposed street work in coordination with other work systems and utility projects to avoid conflict and/or damage to newly placed  asphalt or concrete. 

This strategy builds community trust, ensures City departments and outside partners are on the same page when conducting street maintenance, maximizes resource utilization, and helps improve product delivery.  

Significance

Maintaining existing roads and transportation network in tandem with snow and ice control services helps to ensure safe transportation modes for the community.  Satisfaction with Arvada street condition is  measured utilizing the Community Survey.  Results gathered from the 2019 Community Survey underscore the need for the City to focus on street maintenance.

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

This prioritization will assist the Streets Division to plan, organize, and prioritize which areas will receive concrete replacement prior to asphalt work. 

Understanding the annual type of work and scope provides the information and data needed to plan and budget accordingly.

Description

In 2020 the City Pavement Management Team identified that the current pavement management system (PMS) needed to be upgraded. The product selected as the best solution was a software product named RoadMatrix, owned by Stantec Consulting Services.The team contracted with Stantec Consulting Services Inc to perform the following evaluation and analysis of all City paved streets:

  1. Surface Distress and Roughness
  2. Falling Weight Deflectometer
  3. Ground Penetrating Radar
  4. Coring

The data collected will be down loaded into RoadMatrix  pre-installation. The new PMS will integrate with the City's current asset management software, CityWorks. Previous analysis completed by Atkins International involved sampling the street segments at specified intervals. The Stantec analysis is inclusive and reads the entire street surface. The data will be comprehensive with greater accuracy, providing the software the capability to produce sophisticated data driven decisions using the decision tree process and modeling for various treatment types and maintenance requirements.

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 Stantec team performed the following services in 2020:

  1. Surface Distress and Roughness
  2. Falling Weight Deflectometer
  3. Ground Penetrating Radar
  4. Coring
  5. City wide pavement condition assessment with the Stantec Automated Pavement Data Collection vehicle
  6. Data Entry and Update existing pavement
  7. Run pavement management scenarios
  8. Summary report/project documentation
  9. Verification of section widths (for new roadway sections)
  10. Implementation and integration of a upgraded pavement management system. RoadMatrix


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

The analysis will be performed by utilizing the new PMS to model and/or follow decision tree samples. Initially this analysis will be vetted by Stantec providing the Pavement Management Team with random samples to take into the field and ground proof to verify alignment with the software, making any adjustments with the decision tree criteria. Additionally, the new PMS will include the city divided up in thirds as designed within the table.

Data Source

Data is obtained through RoadMatrix database used to track pavement condition, quality and rideability. 

Obtained through the MicroPaver database used to track pavement condition rating.

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

The data provided in the table demonstrates current and historical funding and identify where we have met funding goals. The differential between 2019 and 2020 occurred as a result of carry forward funds and a change in the strategic approach of the program.

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.
