What act states that the land between mean low tide and the line of vegetation is considered a public beach?

The Texas Open Beaches Act is the legislation that defines the land between the mean low tide and the line of vegetation as public beach. This act was established to ensure that coastal areas remain accessible to the public and to protect public rights over certain coastal lands in Texas. The underlying principle is to promote public use and access to the shoreline, acknowledging that the beach is a vital resource for residents and visitors alike.

In contrast to the Open Beaches Act, the other options refer to different legal contexts. The Eminent Domain Act pertains to the government's power to take private property for public use, generally with compensation, but does not specifically address coastline access. The Public Access Act, while it may seem relevant, does not specifically define the boundaries of public beaches as the Open Beaches Act does. The Coastal Preservation Act focuses on environmental protection of coastal areas rather than public access rights. Thus, the Texas Open Beaches Act is correctly identified as the legislation that asserts public entitlement to the area between mean low tide and the line of vegetation.
