22 Widespread inundation flooding occurs in the residential yards and woodlands along the creek upstream and downstream from Rainbow Drive. The flood waters will be 2 to 3 feet over the bridge and road. County officials will have the road closed. The water will be up to 14 feet deep in portions of backyards of several homes off Kings Park Circle...Rainover Drive...Rainshower Drive and Calumet Road. Several of the homes will be flooded with 1 to 3 feet of water. The water level will enter the USGS gage house.
20 Major flooding begins with widespread inundation of the residential yards and woodlands along the creek upstream and downstream from Rainbow Drive. The flood waters will top the bridge and be around one foot deep over the road. County officials will close the bridge. The water will be up to 12 feet deep in portions of backyards of several homes off Kings Park Circle...Rainover Drive...Rainshower Drive and Calumet Road. Some of the homes will begin to flood.
19 Significant flooding continues to expand into the residential yards and woodlands along the creek upstream and downstream from Rainbow Drive.
