Environmental Protection Maryland 3 Minutes Read ยท published February 08, 2026 Flag of Maryland

Introduction

In Baltimore, Maryland, developers, contractors, and property owners must secure the correct stormwater permits before building, grading, or altering impervious surfaces that affect runoff. The City of Baltimore enforces local stormwater controls alongside Maryland state stormwater and construction NPDES requirements. This guide explains which office issues permits, the basic application path, enforcement and appeals, and practical steps to apply, pay, report violations, and request inspections.

What permits apply

Permits commonly required in the Baltimore area include local stormwater management approvals, erosion and sediment control permits for land disturbance, and state construction stormwater (NPDES) permits where applicable. The primary municipal contact for local stormwater review and permits is the Baltimore Department of Public Works (Baltimore Department of Public Works)[1].

Where to submit applications

  • Submit local stormwater and erosion control plans to the Baltimore Department of Public Works plan review division.
  • State-level Construction Stormwater (NPDES) permit applications are submitted to the Maryland Department of the Environment when projects meet state thresholds.
  • Contact municipal permitting staff to confirm required forms and submittal format (electronic or paper).
Confirm whether both city and state permits are required before starting construction.

Penalties & Enforcement

The City of Baltimore enforces stormwater and erosion control requirements through inspections, notices of violation, stop-work orders, and potential legal actions. For state-covered activities, Maryland Department of the Environment can also issue enforcement actions. Specific penalty amounts and fee tables for civil fines or daily penalties are not specified on the cited municipal page[1].

Typical enforcement elements to expect include:

  • Inspections by municipal enforcement officers or by MDE for state permits.
  • Stop-work orders and orders to correct noncompliant erosion or stormwater controls.
  • Civil penalties, liens, or referral to the courts where corrections are not made.
  • Complaint and reporting channels through the Department of Public Works.

Escalation, appeals, and time limits

The municipal page does not list dollar amounts, escalation ranges, or exact appeal deadlines; those details are not specified on the cited page[1]. Generally, the process includes notices with cure periods, administrative hearings or appeals to an environmental board or similar municipal reviewer, and judicial review options. Permit holders should request appeal procedures and deadlines in writing when notified of enforcement.

Defences and discretion

Common defences include showing an approved permit or variance, demonstrating prompt correction, or proving that conditions were outside the permit scope. Municipal officials often have discretion to issue compliance orders before assessing fines; specific statutory defences and discretion language is not specified on the cited page[1].

Common violations

  • Failure to install or maintain erosion and sediment controls.
  • Unpermitted land disturbance or alteration of stormwater features.
  • Failure to submit required stormwater plans or inspection reports.

Applications & Forms

Municipal application names, form numbers, fees, and exact submission addresses or portals vary by project type. The cited municipal page lists contact and program responsibility but does not publish a single consolidated fee schedule or form set on that page; fees and form numbers are not specified on the cited page[1]. Applicants should request the current application packet and fee schedule from the Department of Public Works plan review unit.

How to apply

  1. Determine if your project triggers local stormwater or erosion controls and whether state NPDES coverage is required.
  2. Prepare stormwater management plans, grading and erosion control drawings, and required reports stamped by a licensed engineer if applicable.
  3. Obtain and submit the correct application forms and pay applicable fees to the Baltimore Department of Public Works.
  4. Schedule required inspections during construction and submit final as-built documentation to close out permits.
