In August 2010, the National Aquarium assembled, planted, and launched a [[floating island|floating wetland island]] designed by Biohabitats in Baltimore's Inner Harbor.<ref>{{cite web |url=http://www.aqua.org/care/conservation-initiatives/floating-wetland-island |title=Floating Wetland Island |publisher=National Aquarium |access-date=February 6, 2016 }}</ref> Hundreds of years ago, Baltimore's harbor shoreline would have been lined with tidal [[wetland]]s. 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.<ref>{{cite web |url=http://www.spinsheet.com/the-floating-wetlands-of-baltimores-inner-harbor/ |title=The Floating Wetlands of Baltimore's Inner Harbor |date=March 13, 2015 |last=Kellett |first=Pamela Tenner |publisher=SpinSheet |access-date=February 6, 2016 }}</ref> 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 wetland|constructed tidal wetland]].<ref>{{cite web |url=http://www.biohabitats.com/projects/baltimore-healthy-harbor/ |title=Baltimore Healthy Harbor Initiative Pilot Projects |publisher=Biohabitats |access-date=February 6, 2016 }}</ref>

Other projects to improve water quality include the Blue Alleys project, expanded street sweeping, and stream restoration.<ref name="ew20151217" />
