Baltimore
Other water pollution control

In August 2010, the National Aquarium assembled, planted, and launched a floating wetland island designed by Biohabitats in Baltimore's Inner Harbor. Hundreds of years ago, Baltimore's harbor shoreline would have been lined with tidal wetlands. Floating wetlands provide many environmental benefits to water quality and habitat enhancement, which is why the Waterfront Partnership of Baltimore has included them in their Healthy Harbor Initiative pilot projects. Biohabitats also developed a concept to transform a dilapidated wharf into a living pier that cleans Harbor water, provides habitat and is an aesthetic attraction. Currently under design, the top of the pier will become a constructed tidal wetland.

Other projects to improve water quality include the Blue Alleys project, expanded street sweeping, and stream restoration.
