Flooding in Sarasota and Manatee Counties 26-27 August, 2017

The map above and below shows the

The aerial photo and map above illustrates the floodway and floodplain in and near the Carlyle Development in Palm Aire in Manatee County north of Whitfield and east of 45th Street East.  The area drains to the north and east via Rattlesnake Slough located on the west and north edge of the development, draining east across Honore Avenue to Ward Lake.  The violet shows the flood way along Rattlesnake Slough and the lighter colors depict the 100 year flood plain.

On August 26, 2017 Creekside Trail north and east of Whitfield was inundated with over two feet of water, destroying some cars and very nearly flooding many homes. This area is outside the 100 year flood plain, indicating that the flood exceeded the 100 year flood. 

The drainage of the development depends on a clear Rattlesnake Slough providing an unimpeded drain. The Slough has not been cleaned for many years and is blocked by numerous fallen trees, slowing and blocking drainage. This impeded drainage would have increased flooding last week, and will likely lead to flooding in the future, especially if we are hit by a hurricane. The Slough must be cleared, hopefully before the next major rain.

Sarasota-Bradenton International Airport set daily rainfall records BOTH Saturday and Sunday - with over a FOOT of rain in total! A Flood Watch will continue for Manatee and Sarasota counties until Monday evening. Rounds of heavy rainfall will continue across our area this evening and Monday before drier air filters in for the middle of the work week.

The disturbance that brought this very heavy rainfall to the Bay area this weekend will likely develop into Tropical Storm Irma off the coast of Georgia overnight. The storm will bring heavy rainfall and gusty winds to the Carolina coastline over the next couple of days.
