Baltimore City Council presses for accountability and repairs after 2024 fires exposed conduit system vulnerabilities

Council oversight focuses on city-owned underground network used by BGE and other utilities

Baltimore City Council members are seeking detailed answers about the condition, management, and repair strategy for the city’s underground conduit system following a series of fires in 2024 that disrupted power, displaced residents, and damaged property in the downtown corridor.

The conduit system is a city-owned network of underground ducts and manholes that carries electric and communications infrastructure. Baltimore Gas and Electric operates within the system under an occupancy agreement that includes payments and commitments to perform capital improvements while the city retains ownership.

2024 incidents brought renewed scrutiny to aging infrastructure

In 2024, multiple underground events underscored the risks associated with the dense, aging network beneath central Baltimore streets. On Jan. 25, 2024, an underground fire in the 300 block of North Charles Street produced smoke from multiple manholes and prompted a power shutdown in the area to allow responders to extinguish visible fire. City officials reported the incident affected underground electrical conduits and temporarily disrupted emergency service communications around 1 a.m.

Additional incidents followed in 2024, including a June fire linked to a transformer box beneath the Charles Towers parking garage area and a major September fire near North Charles and West Pleasant streets that displaced residents and heavily affected nearby businesses. The September event also contributed to extended closures and prolonged repair activity.

Independent findings on the September 2024 Charles and Pleasant fire

An engineering review commissioned by the city concluded the September 2024 fire was triggered by the detonation of combustible gases that had accumulated in a manhole and connecting ductwork over time. The findings described conditions that allowed fire to spread through connecting ducts and into nearby buildings, amplifying damage and disruption.

The review also documented infrastructure challenges consistent with a legacy system, including overcrowded underground spaces, components described as roughly a century old in some locations, and conditions that investigators said remained unacceptable months after the incident.

What council members want clarified

In council discussions and hearings on the conduit system, elected leaders have emphasized the need to establish clear responsibility and timelines for reducing risk and preventing repeat incidents in a high-traffic, high-density area. Key lines of inquiry include:

• How inspection and maintenance are scheduled, documented, and verified across the city-owned network
• What immediate mitigation steps have been implemented at high-risk manholes and ducts
• How capital investments are prioritized and coordinated with street and sidewalk work
• What monitoring and detection systems are being deployed to identify hazardous conditions earlier
• How the city and utilities will measure progress and report results to the public

Repairs and upgrades to the underground network are expected to continue in phases as the city and utilities address damaged sections, evaluate conditions block by block, and implement safety recommendations such as expanded monitoring and improved maintenance practices.

City officials have described the conduit system as a critical asset serving a large portion of Baltimore’s core. Council leaders say the next steps must be defined by verifiable benchmarks, documented maintenance standards, and a coordinated plan to reduce the likelihood of future underground fires.
