Floodplain Management
New Updates Proposed to the Floodplain Ordinance

Changes to the City's floodplain management requirements and procedures are proposed to comply with Federal and State regulations. The City worked with Maryland Department of Environment (MDE) and FEMA for the past year to draft updates to the City's Floodplain Ordinance to maintain participation in the National Flood Insurance Program (NFIP).Two significant changes to the City's current regulations are required: 

  • Establish a new Floodplain Permit process, with more rigorous tracking and record-keeping requirements for permitted floodplain disturbance. 
  • Eliminate previously allowed exemptions from floodplain regulation for public facilities and projects, utilities, fences and play/seating equipment.
