SB 523 Maryland Senate · 2026 Regular Session

Department of Natural Resources - Water Resources - Identification of Vernal Pools (Jack Cover Vernal Pools Act of 2026)

SB 523 requires Maryland's Department of the Environment to create regulations protecting "qualified vernal pools" - seasonal wetlands that don't meet federal wetland criteria but support species like wood frogs and salamanders. It mandates the department to maintain a list of these pools, establish protective buffers, and require developers to avoid harming them during activities like construction. If harm is unavoidable, developers must minimize damage and provide compensation through the department. This directly affects landowners, developers, and construction projects near these pools, adding regulatory requirements similar to those for existing wetlands. The bill does not change current protections for federally recognized wetlands.

MODERATE
The bill was finalized as an enrolled act, changing its title to the 'Jack Cover Vernal Pools Act of 2026' and removing the original explanatory preamble. The core regulatory requirements for identifying and protecting vernal pools remain unchanged, but the bill now includes a new definition for 'Obligate Species' to clarify which animals depend on these habitats.
Scope change
The bill's scope remains focused on requiring the Department of the Environment to identify and protect vernal pools that do not meet federal wetland standards, but the removal of the preamble simplifies the legislative text.
