Wetlands and Waterways Program

The Maryland Department of the Environment’s Wetlands and Waterways Program protects Maryland wetlands and waterways from loss and degradation. This protection is achieved through the regulation of the draining, dredging and filling of tidal and nontidal wetlands, the nontidal wetland buffer and waterways, including the nontidal​ 100-year floodplain through a permitting or authorization process implemented in close coordination with the federal government (specifically, the Army Corps of Engineers). While there are some exemptions from permitting requirements for certain activities, permits or letters of authorization from the State are generally required if a property owner plans to undertake an activity that results in the draining of a wetland or the addition of fill materials to a State regulated wetland or waterway. Examples of activities which require permits from the Wetlands and Waterways Program include building a new pier, adding a platform or boat lift to an existing pier, dredging a boat slip, putting in a bulkhead, filling in a nontidal wetland or buffer for the construction of a structure such as a shed or the expansion or creation of a patio or driveway, and, creating a stream crossing or putting a utility pipeline under a stream. The Wetlands and Waterways Program also provides Maryland-regulated floodplain and FEMA Floodplain information to the public.


The Wetlands and Waterways Program continues to accept and process new incoming Joint Permit Applications (JPAs) during the COVID 19 pandemic and resulting public health emergency. We are operating largely through telework with a select number of staff on-site at Montgomery Park to in-process, screen, and distribute the paper applications, as well as to prepare final documents. Our goal is to provide continuity of our operations during this time. However, out of an abundance of caution, to protect the public as well as our Program staff from potential exposure, we have adjusted our on-site pre-application meetings and post-application site visits protocols involving multiple parties. Under the current conditions, email is the best mechanism to reach us at this time, however our phone lines remain open. If you have questions please contact: Amanda Sigillito/Nontidal Wetlands (amanda.sigillito@maryland.gov); William Seiger/Waterway Construction (William.Seiger@maryland.gov); or Tammy Roberson/Tidal Wetlands (Tammy.Roberson@maryland.gov).
