MD HB613

Exempts Calvert County and St. Mary's County from Maryland's general statewide requirements for nonstructural shoreline stabilization measures, creating a separate regulatory framework for these two counties

Requires property owners in these counties to use living shorelines or nonstructural stabilization measures for erosion protection, with waivers available for areas with excessive erosion, heavy tides, or insufficient space

Defines "high-energy environment" (fetch >2 miles, slope >5%, erosion >2 feet/year) and "medium-energy environment" (fetch 0.5-2 miles, slope 2-5%, erosion 0.5-2 feet/year) with specific technical criteria

Transfers regulatory authority to the Calvert and St. Mary's Soil Conservation Districts, which must adopt implementing regulations including a waiver process and requirement that projects withstand at least a 10-year storm event

Requires cross-certification between the two soil conservation districts: projects designed by one district must be reviewed and certified by the other before construction can begin
