Floodplain and Wetland Restoration- tries to mimic the interaction of groundwater, stream
base flow, and vegetative root systems- key components of a stream corridor under presettlement
(pre-1600s) conditions. The interaction among these elements provides multiple
benefits, including the filtering of sediments and nutrients through retention of frequent high
flows on the floodplain, removal of nitrates from groundwater, reduction of peak flow rates,
groundwater recharge/infiltration, reduced erosion, control non native invasive species, and an
increase of storage and reduction of flood elevations during higher flows.
How can you apply this in your park? Floodplains should remain natural without constructed
facilities; however low-impact accessible paths may be included to invite park visitors to walk
among native vegetation and view wildlife. Existing wetland should be protected and restored
to enhance their ecological benefits such as increasing water quality, reducing stormwater
impacts, and providing critical habitat for a variety of species. Boardwalks and viewing decks
can provide access to wetland areas for environmental education. Educational signage can be
installed to teach park visitors the critical role floodplains and wetlands play in the environment
