Flood Impacts & Photos

18	Major Flood Stage. Extremely rare and catastrophic flooding of the Reedy River is developing within the city of Greenville with disastrous impacts to property. Extraordinary flooding exceeding 6 ft deep is overwhelming low-lying areas including the Swamp Rabbit Trail and Unity Park. Floodwaters are likely impacting businesses upstream and downstream of Unity Park. Significant roadway flooding may be imminent or ongoing near Hampton Ave, Willard St, W Washington St, Hudson St, and Westfield St.
14	Moderate Flood Stage. Hudson St is likely inundated with 12-18 inches of floodwaters. Expansive flooding of Unity Park is ongoing with more significant inundation of the Swamp Rabbit Trail from Unity Park downstream to Cleveland Park. Significant inundation over 1-3 feet deep is likely beginning for low-lying areas, including the Swamp Rabbit Trail, from Westfield St to River St. Flooding along the Reedy River near the Peace Center and Japanese Dogwood Ln is underway.
12	Minor Flooding continues. Extensive flooding of Unity Park is ongoing, with floodwaters 1-3 feet deep. Increasing inundation of low-lying areas adjacent to and including the Swamp Rabbit Trail is ongoing. Trail inundation of less than 6 inches deep is ongoing between Westfield St and Hudson St. Floodwaters are about 6-12 inches below the Hudson St bridge. Cleveland Park flooding is likely during heavy rain along Richland Creek including along Lakehurst St.
11	Minor Flood Stage. Closure of portions of the Swamp Rabbit Trail is like, especially near the River St underpass. Cleveland Park and Lakehurst St are closed due to backwater flooding along Richland Creek. Floodwaters of 1-2 feet deep are inundating the lowest levels of Unity Park. Backwater effects along Long Branch may be causing flooding of adjacent low-lying areas, including near Lily St and Westside Park.
9	Action/Advisory flooding continues. Flooding of low-lying areas along the Swamp Rabbit Trail is beginning. If Reedy River rises are due to heavy rainfall over Berea and downtown Greenville, flooding along Richland Creek is either ongoing or already occurred, forcing closure of Cleveland Park. Heavy rainfall over Berea will cause flooding of W Blue Ridge Dr near Arch St due to poor drainage. Flooding of a mobile home's yard at Brushy Creek on Ross St is also possible forcing evacuation.
8.5	Action/Advisory Stage. The Reedy River is beginning to exceed bankfull in a few locations along the Swamp Rabbit Trail with flooding of adjacent low-lying areas imminent. The lowest elevations of Unity Park are starting to flood, including along the trail under the pedestrian bridge. The Swamp Rabbit Trail is beginning to flood at the River St underpass.
