Covered employee: Any employee who works at a site with 50 or more employees in Maricopa County, Arizona. This includes full-time and part-time employees.

Covered employer: Any organization (private, public, or non-profit) with 50 or more employees at a single worksite in Maricopa County, including Phoenix, Tempe, Scottsdale, Mesa, Glendale, Chandler, and other county municipalities.

To comply with the Maricopa County Travel Reduction Program:

1. Submit a baseline travel reduction plan within 90 days of reaching 50+ employees
2. Designate a transportation coordinator responsible for program implementation
3. Conduct annual employee commuting pattern surveys during designated periods
4. Develop and implement strategies to reduce single-occupancy vehicle commuting
5. Achieve progressive SOV reduction targets: 10% annually for 5 years, then 5% for 3 years, until reaching maximum 60% SOV rate
6. Maintain documentation of program implementation and employee participation
7. Submit updated plans and survey results annually to demonstrate progress

The Maricopa County Travel Reduction Program requires employers to develop comprehensive plans to reduce single-occupancy vehicle commuting. Organizations must designate a transportation coordinator, conduct annual employee surveys, and implement strategies to achieve progressive reduction targets toward a maximum 60% SOV rate. Plans are submitted to the Maricopa County Travel Reduction Program Regional Task Force for review and approval. Employers must demonstrate measurable behavioral changes in commuting patterns, not just offer benefits. The program includes enforcement mechanisms for non-compliance.

The mandate covers all employee commuting activities and requires implementation of strategies to reduce single-occupancy vehicle trips. This includes:

Covered:

• Employee commuting pattern surveys
• Comprehensive travel reduction plans
• Alternative transportation promotion
• Designated transportation coordinator responsibilities
• Documentation of program implementation and results
• Progressive reduction targets toward 60% SOV maximum

Not covered:

• Business-related travel during work hours
• Visitor transportation
• Delivery services and logistics
• Fleet vehicle operations unrelated to commuting

Non-compliance with the Maricopa County Travel Reduction Program can result in civil penalties, including fines for failure to submit required plans, conduct annual surveys, or demonstrate good faith implementation efforts. The program's enforcement focuses on implementation of approved strategies rather than achieving specific reduction targets, though persistent failure to make progress toward SOV reduction goals may trigger enforcement actions.

While the program itself is mandatory, employers can realize significant financial benefits through compliance strategies:

• Federal pre-tax commuter benefits allowing savings up to $325/month per employee (2025 limit)
• Employer FICA tax savings of 7.65% on pre-tax benefit amounts
• Reduced parking facility costs and demands
• Potential eligibility for additional environmental or transportation grants
• Enhanced employee recruitment and retention through valuable commute benefits
• Improved corporate sustainability profile

The mandate applies only to Maricopa County, Arizona. This includes the cities of Phoenix, Tempe, Scottsdale, Mesa, Glendale, Chandler, and all other municipalities within county boundaries.

The program is in effect throughout Maricopa County, Arizona, covering all municipalities within the county borders.
