Riverside Filter Marsh

Located to the east of Goodlette-Frank Road along the shoreline of the Gordon River, the Riverside Filter Marsh was built to lower amounts of pollutants entering Naples Bay. Prior to construction of this 1.4 acre project, the city drained stormwater from a 226 acre urbanized area directly into the Gordon River without treatment.  This runoff carried phosphates and nitrates from fertilizer, bacteria, and other pollutants into the upper reaches of Naples Bay.  The filter marsh now intercepts the stormwater and naturally treats it prior to discharge into the river.
 
By running stormwater through a constructed wetland marsh, plus changing the flow from a point flow to a sheet flow, amounts of pollutants flowing off the City and into Naples Bay have been reduced.  Further, the marsh provides habitat for wetland plants and animals. Otter, woodstorks, egrets, and herons are already using the site.
