Francis Scott Key Bridge Incident Updates

Sediment and Erosion Control oversees active construction sites for proper grading and sediment and erosion control compliance, as well as investigates drainage complaints. Inspectors check earth-moving activities to ensure the disturbed area is stabilized sufficiently to minimize the potential for erosion and sediment transport from the worksite, as specified by an approved sediment and erosion control plan.

Process for Large Projects

  1. Large projects are designed by professional engineers hired by the landowner.
  2. A plan is designed based on standards and specifications for soil erosion and sediment control from the Maryland Department of Environment.
  3. Baltimore County's Soil Conservation District reviews and approves the plan.
  4. Baltimore County inspects the actual work for compliance with the plan.

Third-Party Inspection Program

Developers may utilize a County-approved, third-party inspector to monitor and enforce sediment and erosion controls at active construction sites.

Process for Qualifying as a Third-Party Inspector

Grading Permits and Regulations

A grading permit is required:

  • If the proposed work disturbs over 5,000 square feet of surface area or over 100 cubic yards of earth.
  • For any grading activities in any watercourse, floodplain, wetland area, buffers (stream and within 100 feet of tidal water), habitat protection areas or forest buffer areas, including forest conservation areas.

State and County regulations require property owners and holders of permits to install measures that will filter water run-off.


The grading regulations contain Section 1.04 of the Code of the Baltimore County Regulations (COBAR) which pertains to excavating, grading, sediment control and forest management in Baltimore County.
