HB 613 Maryland House of Delegates · 2026 Regular Session

Department of the Environment - Waivers for Living Shorelines and Nonstructural Shoreline Stabilization Measures - Regulations and Scoring System

HB 613 requires property owners in Calvert and St. Mary's Counties to use natural erosion control methods (like marsh creation, native plants, and oyster reefs) instead of hard structures (such as seawalls) for shoreline stabilization. It exempts these counties from general state requirements for nonstructural measures and creates a new waiver process where owners must demonstrate to the Department of Natural Resources that natural methods are not feasible due to factors like extreme erosion or narrow shorelines. The bill defines "living shorelines" as projects using natural materials and ecological principles to absorb wave energy and restore habitats, while still allowing structural measures in specific high-energy areas. This directly affects property owners along navigable waters in those two counties, changing how they must address shoreline erosion.

MINOR
The bill was finalized as an Enrolled Bill, moving it from a draft stage to a version ready for the Governor's signature. Substantively, the bill reorganized the legal framework by repealing and reenacting existing shoreline laws to update the definitions of 'Living Shorelines' and 'Nonstructural Stabilization Measures.' The updated definitions now explicitly include specific natural elements like submerged aquatic vegetation and native plants, while also clarifying that nonstructural measures can include low-profile structural elements like oyster domes.
Scope change
The bill's scope was expanded by formally repealing and reenacting the relevant sections of the Annotated Code of Maryland, allowing for the insertion of new definitions and clarifications regarding shoreline stabilization projects.
DEFINITION

Updated the definition of 'Living Shoreline' to explicitly list specific natural elements such as submerged aquatic vegetation and native grasses, and clarified that it may include low-profile structural elements like oyster domes.

Refined the definition of 'Nonstructural Shoreline Stabilization Measure' to ensure it is dominated by tidal wetland vegetation but designed to preserve the natural shoreline and establish aquatic habitat.

REQUIREMENT

Reorganized the statutory text to repeal and reenact existing sections, which allows the Department of the Environment to implement new regulations and scoring systems for evaluating waiver requests for these specific shoreline measures.
