Keep America's Waterfronts Working Act of 2011 - Amends the Coastal Zone Management Act of 1972 to direct the Secretary of Commerce, acting through the National Oceanic and Atmospheric Administration (NOAA), to establish a Working Waterfront Grant Program to award matching grants, through a regionally equitable, competitive funding process, to coastal states with approved working waterfront plans to preserve and expand access to coastal waters for persons engaged in commercial fishing, recreational fishing businesses, aquaculture, boatbuilding, or other water-dependent coastal-related business.
Allows such states to allocate grants to eligible local governments, agencies, or nongovernment organizations.
Authorizes the Secretary to award planning grants to coastal states to develop or revise comprehensive working waterfront plans.
