Sustainability - is the endurance of systems and processes.

In 1954 U.S. Congress Document 389 created Marina del Rey from 950 acres of Ballona Wetlands. To compensate for the loss of marshlands (bird habitat) they promised:

Elected and agency officials, developers and counsel should take notice that they may be liable under these enforcement provisions of the Clean Water Act: Direct Discharge.

Ballona Lower Wetlands in 1952. Notice Lincoln Blvd is a levee road surrounded on both sites by water.

When a developer uses the word "restoration" do you think they mean the wetlands state before Marina Del Rey Harbor was built in 1954?  Or does the developer mean bulldoze current animal homes, and replant a careful, artful designed and manicured modern native plant selection, and hope the animals come back?  Suitable as a tourist attraction and for hotel guests to gaze upon from their hi-rise rental rooms?
