Northern California River Watch, an environmental group based in Petaluma, is suing the Bayshore Mall and its previous corporate owners, General Growth Properties, for failing to restore five acres of wetlands.

The nonprofit alleges that GGP failed to comply with a requirement in the Coastal Development Permit it was issued way back in 1985. According the the complaint, the permit required restoration of 5.17 acres of wetlands on the mall property, and the mall's owners did no such restoration, thus violating the California Coastal Act.

One possible wrinkle: The Bayshore Mall changed owners back in January as part of General Growth Properties' post-bankruptcy restructuring.

River Watch is seeking $30,000 in civil fines, plus another $15,000 fine for each and every day that the owners have been in violation. Anyone have a calculator?
