WOODBRIDGE, Va. – Nearly six months after the grand opening of Prince William County’s first commuter parking garage, new data shows the facility is being used far below capacity while operating costs continue to climb, renewing questions raised even before construction began.
The Neabsco-Potomac Mills Commuter Garage, a $53.5 million project located near Opitz Boulevard and Interstate 95, officially opened in November 2024. Since then, the county has spent $186,016 on operational expenses, according to recently released county records. The seven-story facility features 1,400 parking spaces, resulting in a construction cost of $38,214 per space.
Cost Breakdown
Records from Prince William County show:
- Electricity (Aug 2024 – May 2025): $21,508
- Water (Sept 2024 – May 2025): $558 (only one month of recorded usage)
- General maintenance work orders: $101,645
- Custodial services (since Dec): $20,459
- Groundskeeping and cleanup: $17,654
- Security guard services: $13,997
- Estimated snow removal: $10,000
- Porta-john rental: $195
Garage Usage Still Low
Despite being fully operational, usage of the garage remains modest.
- November 2024: 187 visits
- April 2025 (peak month): 4,902 visits
- May 2025: 4,488 visits
Assuming one visit equals one space used per day and accounting for 30 days per month, the April utilization rate is only about 11.7% (4,902 of 42,000 possible daily space uses). Average parking durations have increased over time—from 1 hour, 55 minutes in November to 5 hours, 40 minutes in May—indicating the garage is primarily used by long-term parkers such as commuters.
The third floor is the most heavily used, registering over 2,300 visits in May and average parking durations exceeding 9 hours. The usage of the ground, fourth, and fifth floors has also increased, although it is far from being complete.
OmniRide Relocates to Garage
In December 2024, one month after the garage opened, OmniRide officially relocated its eastern transfer hub to the Neabsco facility. The move included rerouting several Express, Metro Express, and Local bus routes to begin and end service at the garage. Previously, these routes served the OmniRide Transit Center at 14700 Potomac Mills Road.
This relocation was part of a significant service overhaul aimed at creating a true multimodal hub with seamless connections to the nearby I-95 Express Lanes, which now feature a dedicated ramp at Opitz Boulevard. The strategy, according to transportation planners, is designed to support long-term growth and reduce single-occupancy vehicle traffic.
Early Warnings Realized?
The data appears to validate concerns raised during the project’s approval phase.
In September 2022, when the Board of County Supervisors approved the final design, Coles District Supervisor Yesli Vega cast the lone dissenting vote. She pointed to a Virginia Department of Transportation study showing nearby commuter lots were only 20% full, questioning the financial wisdom of constructing a massive parking structure.
“Help me understand how this makes good fiscal sense,” Vega said during the meeting, addressing Transportation Director Rick Canizales.
At the time, officials stated that abandoning the federally funded project would result in financial penalties and the forfeiture of funding. Canizales defended the garage as a forward-looking investment, noting the county was already under contract with a construction firm and that future transit usage was expected to grow.
County Officials Offer No New Comments
Potomac Local News contacted all members of the Prince William Board of County Supervisors for comment on the garage’s current usage and cost. None responded, except for Potomac District Supervisor Andrea Bailey, who replied via email with a brief “No comment.”
