Baltimore Storm Drain Cleaning - City Bylaws

Utilities and Infrastructure Maryland 3 Minutes Read ยท published February 08, 2026 Flag of Maryland

Baltimore, Maryland requires coordinated action between city agencies and property owners to keep storm drains clear and functioning. This guide explains who is responsible for public vs private storm inlets, how the City schedules inspections and cleanings, reporting and complaint paths, and what to expect from enforcement. It is designed for residents, property managers, contractors, and community groups in Baltimore seeking clear steps to prevent flooding and comply with municipal requirements.

Who is responsible

Public curb inlets and storm drain pipes located in the public right-of-way are maintained by the Baltimore Department of Public Works (DPW). Private inlets and drainage features on private property are typically the property owner's responsibility. For official program details and operational scope, see the City DPW stormwater program.[1]

If a drain on the street is clogged, report it to the city before attempting street-side work yourself.

Typical cleaning schedule and triggers

Scheduled cleaning frequency varies by basin, flood history, and neighborhood priority; high-risk corridors and drainage basins may receive recurring inspections, while others are cleaned reactively after storms. Triggers for cleaning include public reports, routine inspections, post-storm debris surveys, and capital projects.

  • Routine inspections in high-priority basins (frequency not specified on the cited page).
  • Post-storm or emergency cleanings when accumulated debris causes backups or flooding.
  • Citizen reports submitted via Baltimore 311 or DPW service request channels.

Penalties & Enforcement

Enforcement responsibility for stormwater infrastructure and illicit discharges rests with the Baltimore Department of Public Works and related enforcement units; applicable municipal code provisions may authorize fines, orders, and abatement actions. The city publishes program and enforcement information through DPW and the municipal code repository.[1][2]

Specific fine amounts and escalation schedules are not clearly listed on the cited municipal pages.
