Objective

We wanted to determine whether the Department of Transportation & Infrastructure’s Fleet Management Division is adequately managing and overseeing the city’s fleet. This includes evaluating the fleet’s funding structure, assessing performance against established goals, and assessing controls over assets.

Background

The Department of Transportation & Infrastructure’s Fleet Management Division oversees and maintains a fleet of over 2,500 vehicles and pieces of equipment belonging to 43 city agencies — not including Denver Police and Fire departments and Denver International Airport. Agencies rely on Fleet Management to service vehicles and ensure they are available for operations.

Why this matters

The city’s vehicles are valuable assets and an essential component of delivering core services to Denver residents and businesses. City agencies rely on the availability and reliability of its fleet to deliver services, and without the proper structure and oversight, the city risks inefficient use of tax dollars and disruptions to critical services such as waste management, street repairs, and parks maintenance.

Findings

FINDING 1 – The fleet funding structure results in Transportation & Infrastructure paying for other agencies’ fuel and maintenance costs

The city changed its fleet funding structure in 2015, but this change does not align with leading practices or with how other cities and counties we looked at manage their fleets.

FINDING 2 – The city is not meeting its targets for vehicle use, availability, and fleet replacement

Vehicle use, availability, and fleet replacement are critical components of the overall goal of ensuring vehicles are available when agencies need them. We found:

  • The city’s vehicle fleet is underused.

  • The city is not meeting its goal of replacing vehicles as they reach the end of their useful lives, increasing maintenance and repair costs.

  • The city missed vehicle availability goals, impacting the rate at which vehicles are available to agencies and affecting the delivery of public services.

FINDING 3 – Inadequate controls create risks of waste and abuse

Current processes and procedures at city facilities may not adequately safeguard fleet assets.

  • Fuel access and activity is not properly managed or monitored, risking inappropriate fuel transactions.

  • Parts storage may be accessed by unauthorized parties and parts are not always tracked to jobs.

Recommendations

1.1 Re-evaluate fleet funding structure – The Department of Transportation & Infrastructure should work with the Department of Finance to evaluate and document whether adopting the internal service fund model for fleet funding is in the best financial and operational interest of the city. After the evaluation, Transportation & Infrastructure and Finance should update the city ordinance and formalize procedures to match the funding structure selected. 

Agency Response: Agree, Implementation Date – Dec. 31, 2025

2.1 Seek authority regarding the city's vehicle fleet – The Department of Transportation & Infrastructure should work with the Mayor’s Office to get operational authority to help manage the city’s fleet more effectively. This could take the form of establishing agreements and a formal process to objectively evaluate the use of the city’s fleet.

Agency Response: Agree, Implementation Date – Dec. 31, 2025

2.2 Optimize vehicle use – Depending on the implementation and results of Recommendation 2.1, the Department of Transportation & Infrastructure should develop and document a formal process for evaluating vehicle usage. It should use the results to work with city agencies to improve vehicle use so that it is in line with available inventory and to achieve the desired vehicle use rate.

Agency Response: Agree, Implementation Date – Dec. 31, 2025

2.3 Identify and document a plan for vehicle replacements – The Department of Transportation & Infrastructure should work with city agencies to identify and document a plan for vehicles that are approaching the end of their useful lives and determine the best course of action for each. If funding is not available to replace a vehicle, the department should document an alternative plan. Implementing this recommendation may be assisted by additional authority obtained from implementing Recommendation 2.1.

Agency Response: Agree, Implementation Date – July 1, 2025

2.4 Develop and document a plan to meet vehicle availability goals – The Fleet Management Division should develop and document a plan to meet vehicle availability goals. The plan should consider rightsizing the fleet as described in Recommendation 2.3, to ensure agencies have access to vehicles at least 95% of the time.

Agency Response: Agree, Implementation Date – March 31, 2025

2.5 Develop and document a plan to address staffing needs – The Fleet Management Division should develop and document a plan to address its staffing needs annually. The plan should include alternative staffing solutions to meet availability goals given the challenges around filling vacancies.

Agency Response: Agree, Implementation Date – July 1, 2025

3.1 Design and document a comprehensive fuel activity review – The Fleet Management Division should create a comprehensive fueling policy that addresses user access, criteria for identifying abnormal transactions, procedures for following up on abnormal transactions, criteria for appropriate use of override codes, preserving override transaction history, periodic monitoring procedures, and training to ensure that users understand and follow the policy.

Agency Response: Agree, Implementation Date – July 1, 2025

3.2 Remove unauthorized users from the driver database – The Fleet Management Division should remove all former city employees from its authorized driver list and develop, implement, and document procedures to keep the list promptly and consistently accurate.

Agency Response: Agree, Implementation Date – July 1, 2025

3.3 Perform a physical security assessment – The Department of Transportation & Infrastructure should perform a full physical security assessment of its buildings and locations where parts are being stored and identify risk-based approaches for securing vulnerable parts.

Agency Response: Agree, Implementation Date – March 31, 2025

3.4 Comply with the parts service-level agreement – The Fleet Management Division should comply with the existing and approved service-level agreement related to linking supervisor’s performance goals to inventory management of stockrooms.

Agency Response: Agree, Implementation Date – March 31, 2025

3.5 Create policies and procedures – The Fleet Management Division should create and document policies and procedures for determining when work should be outsourced. At a minimum, these policies and procedures should include criteria for outsourcing work, a requirement to perform a cost-benefit analysis, roles and responsibilities, and documenting the decision.

Agency Response: Agree, Implementation Date – Dec. 31, 2025

3.6 Review, identify, and correct inaccurate data – The Fleet Management Division should systematically review and identify any instances of inaccurate data in AssetWorks to ensure the data reliable and can be used for informed decision-making.

Agency Response: Agree, Implementation Date – March 31, 2025

3.7 Improve software functionality – The Department of Transportation & Infrastructure should work with AssetWorks and the city’s Technology Services agency to develop and document improvements to AssetWorks’ fleet management functionality as laid out in the original vendor contract.

Agency Response: Agree, Implementation Date – Sept 20, 2025

Auditor's Letter

October 17, 2024

We audited the Department of Transportation & Infrastructure’s Fleet Management Division to determine whether the city’s fleet is adequately managed and overseen. I now present the results of this audit.

The audit found the city’s fleet funding structure results in Transportation & Infrastructure paying for other agencies’ fuel and maintenance costs. Additionally, the city is not meeting its targets for vehicle use, availability, and fleet replacement. The audit also found controls over fleet-related assets are inadequate, creating risks of waste and abuse.

By implementing recommendations for Transportation & Infrastructure to re-evaluate its funding structure, gain authority over the city’s fleet, develop and document plans, and strengthen controls, Transportation & Infrastructure will be better able to optimize the city’s fleet.

This performance audit is authorized pursuant to the City and County of Denver Charter, Article V, Part 2, Section 1, “General Powers and Duties of Auditor.” We conducted this performance audit in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives.

We appreciate the leaders and team members at Transportation & Infrastructure who shared their time and knowledge with us during the audit. Please contact me at 720-913-5000 with any questions.
