Johns Hopkins seeks stormwater waivers for Bayview water loop project

The Baltimore City Department of Public Works posted a public notice on January 14 that Johns Hopkins Health System has applied for both qualitative and quantitative control waivers for a domestic water loop replacement at its Bayview Medical Center campus, 5100 Eastern Avenue. The project covers roughly 1.04 acres and, according to the notice, the applicant is seeking a qualitative control waiver under the City Code after demonstrating restoration to predevelopment runoff conditions. Public comments on the application are due by 4:30 PM on January 29, 2026, and the DPW directs interested parties to the Office of Research and Environmental Protection for more details.

At stake for Bayview and surrounding East Baltimore blocks are how stormwater will be managed during and after construction and whether the proposed work maintains protections against increased runoff and pollution. A quantitative waiver typically relates to the volume and rate of runoff, while a qualitative waiver involves measures to protect water quality. The application asserts that the replacement will restore runoff to predevelopment levels, a key point that shapes whether the city will grant reduced stormwater controls for the site.

Residents near Eastern Avenue should expect construction activity tied to a domestic water loop replacement to be the immediate, tangible impact. Short-term effects can include lane closures, truck traffic, noise, and increased sediment risk if controls are inadequate. For a hospital campus, reliable domestic water infrastructure is critical to patient care and emergency operations, so the project also has a public service rationale that affects both hospital operations and the neighborhood.

This notice is part of the municipal permitting process that gives community members a window to weigh in on technical and neighborhood concerns. Submitting comments by the Jan 29 deadline will ensure the city considers local perspectives on stormwater performance, erosion control, traffic disruptions, and construction timing. The Office of Research and Environmental Protection is the DPW office identified for more information and to receive input.

How the city responds will set the immediate regulatory outcome and influence how construction proceeds. For neighbors and community organizations, this is an opportunity to push for strict erosion and sediment controls, clear construction timelines, and monitoring that preserves nearby streets, storm drains, and waterways. The next steps are agency review of public comments and a city decision on whether to grant the requested waivers, which will determine mitigation requirements and oversight during the Bayview water loop project.
